Beijing, July 23 (Yu Wang) On the 22nd, Beijing time, FINA issued a statement, and decided to warn the Australian Swimming Association and mark houghton for Australian Horton’s refusal to take a photo with Sun Yang at the award ceremony.

　　FINA said that it respects the freedom of speech of athletes, but at the same time, it believes that everyone’s freedom of speech needs to be expressed in the right way.

　　Can’t afford to lose? Sun Yang won the championship and Horton refused to take a photo.

　　In the men’s 400-meter freestyle final of the World Championships, Sun Yang won the championship in 3 minutes, 42.44 seconds, achieving four consecutive championships in the World Championships. This is Sun Yang’s tenth gold medal in the World Championships, and it is also the most powerful proof that "everything in the competitive arena depends on the results".

　　However, at the award ceremony after the game, Australian Horton, who won the silver medal, once again made much ado about nothing and refused to take a photo with Sun Yang on the podium, which also caused boos from the audience. And Sun Yang also ignored, just laugh it off.

　　For Horton’s rude behavior, Sun Yang responded at the press conference that night: "The award is very sacred. You have thousands of unwillingness, but when you stand on the podium, you can disrespect me, but you must respect China."

　　This series of "storms" did not disturb Sun Yang, who entered the competition state. In the men’s 200m freestyle semi-final held on the evening of 22nd, he advanced to the final with a time of 1 minute 45.31 seconds. Tonight, Populus alba will attack the second gold medal in this World Championships.

　　Helpless! Horton made trouble at the Rio Olympics.

　　In fact, Horton’s unprovoked attack on Sun Yang can even be traced back to the Rio Olympic Games three years ago. At that time, before the men’s 400-meter freestyle final, Sun Yang took the initiative to greet him, but he was coldly greeted by his opponent.

　　What is even more jaw-dropping is that Horton beat Sun Yang to win the gold medal in the subsequent competition. However, after winning the gold medal, he openly attacked Sun Yang and called him a "doping player". Horton’s unprovoked slander immediately caused an uproar.

　　In response to Horton’s behavior, a spokesman for the International Olympic Committee once responded: "The audience wants to see fair, just and open sports events. We hope that athletes will adhere to the Olympic spirit and ask each athlete to respect each other."

　　As a party, Sun Yang immediately replied: "We are not friends". The Chinese Swimming Association also formally notified the Australian Swimming Association and asked Horton to publicly apologize for what he had done.

　　Comfortable! FINA issued a statement warning Horton

　　But this time, FINA’s attitude is even tougher. In their statement, they said: "FINA officials analyzed the situation of the men’s 400-meter freestyle award ceremony and decided to send a warning letter to Australian Swimming Co., Ltd. and its athlete Horton."

　　"FINA respects freedom of speech, but it must be done in an appropriate context. Like all major sports organizations, our athletes and their entourage should understand that they have the responsibility to respect FINA regulations and not to use FINA events to make personal statements or gestures. "

　　According to the usual practice, only FINA and the World Anti-Doping Agency are responsible for the investigation of doping in swimmers. When FINA decided that there was no violation in Sun Yang and court of arbitration for sports had not held a hearing on doping control in Sun Yang, Horton’s accusation was obviously groundless.

　　Recently, Sun Yang also issued a certificate through his lawyer, demanding that the hearing be made public to prove his innocence. FINA expressed a clear attitude: "Horton’s protest is currently under trial in court of arbitration for sports, and FINA will not comment on it before the hearing."

　　Condemn! Former executive of Australian anti-doping agency: Horton should be severely punished

　　Many people in the industry also criticized Horton’s loss after the game. Richard Inges, the former CEO of the Australian Sports Anti-Doping Administration, is one of them. He said on his personal social media that Horton should be severely punished for this.

　　Richard Inges, former CEO of the Australian Sports Anti-Doping Administration, said Horton should be severely punished.

　　"I’m not a fan of Sun Yang, but a series of things have been clarified before. Therefore, Horton’s failure to stand on the podium should be severely punished. " He wrote.

　　According to the internationally renowned swimming website "Swim Swam", Horton also "suggested" Italian player Deti who won the third place to stand on the podium before the award ceremony, but the Italian said, "I have paid too much for this bronze medal, and I want to stand on the podium."

　　Not only that, Horton also attracted resistance from foreign netizens on social media. Some netizens said: "Sun Yang’s participation in the competition has proved that he is innocent. I don’t understand that Horton wants to make a big fuss about this." "Why can’t Horton face the reality: he just can’t win Sun Yang?"

　　Interesting! Horton participated in the World Championships by "going through the back door"?

　　Interestingly, Horton, who openly accused others of "counterfeiting" in public, was able to come to Gwangju, and the reasons behind it were also somewhat speechless. According to Australian media reports, Horton did not qualify for the previous World Championships in Australia.

　　After the men’s 400-meter race, the British Daily Mail also wrote that Horton’s move was "very rude" and revealed that he relied on "privilege" to participate in this World Championships. The reason is that Horton’s head coach has discretion.

　　Horton refused to take a photo with Sun Yang at the award ceremony. China News Service reporter Han Haidan photo

　　In the end, Horton also repaid the trust of the Australian Swimming Association with a silver medal, but what he did after the game puzzled the coach: "No one knew he would do this, it was his idea."

　　In sharp contrast, at the women’s 100m butterfly award ceremony on the evening of 22nd, Canadian player McNeil, Swedish star Sjostrom and Australian player mckeown put their palms to the camera, and their hands were written with the words "Chijiang Glazed Flower" and "Never Give Up" to cheer for Chijiang Glazed Flower suffering from leukemia, which also moved everyone.

　　The stadium is a stage for athletes to pursue "higher, faster and stronger", which is pure and full of warmth and emotion. Whether you are skeptical or resentful, please let sports return to their original heart when the starting gun goes off. (End)

　 　 Special feature of 1905 film network　A father is the first man a daughter meets in her life, and every daughter has a definition of a father in her heart.

　 　 In the movie Diary of the Sea Street, 15-year-old Ling (Suzu Hirose) meets her half-sisters Xing, Jia Nai and Qian Jia, who have never met before, at her father’s funeral, and accepts their sisters’ invitation to live in Xiangtian’s old house in Kamakura.

　 　 The film follows the name of the original comic book diary of the Sea Street, instead of Story of the Sea Street, and connects the theme of "getting my father back" with trivial stories. The comic aesthetic style shows that director Hirokazu Koreeda doesn’t intend to make a profound analysis of society this time, but only wants to discuss the eternal topic of "father" in this film "Father is not present".

Poster of Hai Jie Diary

　 　 The death of my father is the beginning of this story. Fifteen years ago, my father left the three sisters because he fell in love with another woman (Ling’s mother) and lost contact with them. The cherry blossoms in Binhai Road bloom and fade, the plums in front of the old house are green and yellow, relatives and friends come and go, and the father never appears. In the process of the growth of the three sisters, the father’s "lack of companionship" is an important reason for the daughters’ "incomplete emotional life", which has become the "introduction" of this film.

Dajiexing (Ayase Haruka)

　 　 I have witnessed the quarrel between my parents and my mother’s sadness. After my mother left home, it was my eldest sister Xing (Ayase Haruka) who took care of the family. Fortunately, she was tough in appearance and extremely fragile in heart. She assumed the responsibility of parents prematurely and longed for a man to rely on. She fell in love with a married man, probably because the other person is a mature man, but as a de facto third party, traditionally, she had to bear the blame of her conscience and hid all her desires very appropriately, only when her younger sister Ling arrived, she inadvertently revealed them.

Er Jie Jia Nai (Masami Nagasawa)

　 　 The second sister, Jia Nai (Masami Nagasawa), is simple in nature. In her memory, she often hears her parents quarreling at night and sees her sister comforting her mother. Her dissatisfaction with her father is more influenced by her sister’s luck. It is her childhood memory that makes her want to be free and happy when she grows up, be cheated by her little boyfriend again and again, and drink and go crazy again and again. Her sister’s luck may comfort her but she can’t tell her to avoid repeating the wrong plan.

Sanjie Qianjia (Kaho)

　 　 Among the four sisters, Qianjia (Kaho), the third sister, is the daughter who has the most vague impression of her father. Because of her vagueness, her feelings for her father are just like that of a daughter’s family who worships her father. Because of her worship, she wants to know more about her father, so when Ling holds the childhood photos of the three sisters treasured by her father, she is the most curious chatterbox. She likes to practice fishing alone at home. When she learned that her father also likes fishing, her excitement was beyond words. "It turns out that my father and I are very similar in this respect." Her boyfriend, like a joke, is a store manager with a grotesque appearance. She was attracted to the store manager because this sports man with six toes missing is passionate about conquering Mount Everest and loves sports as much as his father and is full of adventure.

　 　 Although the film did not deliberately explain the age and gap of the three sisters, from the scale of the wooden pillars in the promenade, we can guess that the age gap between them is not great. However, because of my father’s absence, my eldest sister came to middle age early, my second sister played a rebellious youth, and my third sister stayed in her childhood, just like plum wine brewed in different years, with different shades and tastes. The pillars at home are engraved with the height marks of the daughters’ growth. We can guess that it was their father who carved the mark on the wooden pillar, and the last mark stayed at the age of fifteen.

　 　 The death of my father is also an emotional turning point. Lost fifteen emotions, sealed fifteen years of memories, slowly opened with the arrival of half-sister Ling. The sisters invited Ling to live with them, worried about their younger sister’s future life and hypocritical stepmother, and loved her sister’s kind-hearted and tough personality. Moreover, among the four sisters, only Ling had a complete memory of her father, who often made sardine toast for her and took her fishing together, and never missed the key to her growth. At the last moment of her father’s life, Ling accompanied her father through the last life, and Ling’s body was marked by her father. When they accepted Ling, they actually accepted their father in another way. Because of the arrival of Ling, the family began to appear complete. The elder sister was no longer strict, the second sister had more responsibility and the third sister shared more. In their minds, the vague impression of their father began to become concrete. From Ling’s perspective, what unfolds slowly is the scene where my father and daughters lived together many years ago. The accumulated life in the town is strung together, and the diary is not a story. The plum trees planted by my grandmother in the old house, courtyard and faint pickles flow peacefully in the four seasons of Kamakura. Sardines toast is the memory of Ling and her father’s life together. In the dining hall of the sea cat, Ling found that this food was actually the creativity of the sea cat. A piece of food carries the memories of a full family, and the family is the people who eat many meals together.

　 　 Under the promenade, Ling He, who was drinking plum wine, made a funny laugh. Ling, who came to the old house, was the father who returned to his daughters in another way to accompany her to find the lost innocence in her life. "You can always be here, forever … …” This sentence appeared twice in the film. The first time was when Ling just arrived in Kamakura. Fortunately, she expressed her acceptance and welcome.

　 　 The second time was at the end of the film. Ling, who always felt guilty and thought that she had stolen the happiness of her sisters for fifteen years, opened her heart to her at the top of the mountain. Fortunately, she sincerely said, "You can always be here, forever … …” This sentence is not only for Ling, but also for her father’s confession, for her inner reconciliation with her father, and for her inner love for her father.

　 　 Ling told her sisters that her father said at the last moment of her life, "It would be a wonderful thing if she still has the ability to feel beautiful when she leaves this world!" . At the end of the film, standing by the sea, Yuki and Qianjia and Jianai talk about their father. "He may be a failure, but he must be a very gentle person."

　 　 Father never appeared in the film, but he was everywhere. The train passing through the city meets the cherry blossom avenue in the sea at the corner, and four girls wearing kimonos and playing with fireworks. The film seems a little scattered. What is scattered but not chaotic is the feelings of the four sisters for their father, with a touch of warmth in their sadness. Although their feelings for their father are complicated, their love for their father makes them live and move forward bravely.

　 　 The film begins with his father’s funeral, and ends with the funeral of the boss’s second house in the Haimao canteen. In this film, the director fully shows his seriousness to death and kindness to life, understands his father’s abandonment of his wife and children with the greatest tolerance, and does not accuse him too much of throwing his children to his grandmother’s mother, falling in love with his married sister, trying his best to occupy the second house in the Haimao canteen, and even Ling’s mother as a "third party" because Ling.

　 　 The director confessed with the film: "No one’s soul has fragrance, no one is wrong", life is beautiful, sometimes life is not so beautiful, even so, life is still beautiful.

　 　 Life is like a cherry blossom, a bunch of fireworks, short and beautiful. Life needs such loosening.

Depp joined Hollow Man.

　 　 1905 movie network news Universal Picture’s "Monster Universe" plan is moving forward in an orderly way. A few days ago, the remake of Hollow Man attracted a famous actor to join us. It is reported that Johnny Depp will definitely join the film and play the role of invisible man in the film. In the original film, the invisible man became a killer after being invisible, and there were killers in Depp’s previous screen roles, so this role is more suitable for Depp to interpret.

　 　 The original Hollow Man, filmed in 1933, tells the story of a talented scientist who invented an invisibility reagent that can make people invisible after drinking. Although the effect of the reagent is obvious, unfortunately, the side effects make the scientist become eccentric, and gradually, he becomes an invisible killer. The film depicts the alienation of science and technology to human beings. Although it is exaggerated, the scenes of a large number of invisible people killing people in the film are still chilling. The film has been put on the screen five times. The famous David .S. Goyer once filmed a version in 2007.

The 1933 edition of Invisible Man

　 　 As early as last year, Universal decided to build a "monster universe", hoping to copy the successful experience and bring the famous monsters in the film history such as Dracula, Frankenstein, Frankenstein’s bride, werewolf, invisible man, mummy, and Black Lake Fishman to the big screen. Judging from the progress of the current exposure, the list signed by Universal is big: Tom Cruise just confirmed to join us not long ago, and now Hollow Man has invited Depp to join us. Just from the stunt, this "monster universe" can be described as huge.

　 　 Universal Picture’s Hollow Man will be written by ed solomon, a screenwriter, and the director candidate and release time have not been decided.

It’ s too embarrassing … Although I knew in advance that BYD was going to engage in intelligent driving of the whole car, I really didn’ t expect that it was close to the standard of the whole department. (PS: products under 100,000, this is the second time to start carrying)

The growth rate of China market is higher than that of the whole world.

From 2010 to 2020, the market size of China’s pet industry increased from 13.44 billion yuan to 72.73 billion yuan, with a compound annual growth rate of nearly 20%, which is higher than that of the whole world. In 2020, the US pet consumption market accounts for 41.1% of the world, ranking first, and China accounts for 8.1%. The pet raising rate and the annual consumption of a single pet in China are far below the level of developed countries, and there is much room for growth in the future.

Judging from the proportion of pet expenditure in household consumption, in 2014, the difference in the proportion of pet expenditure in household consumption between China and the United States was 3.1 times, and in 2019, the difference dropped to 1.8 times.

1. The average annual compound growth rate of China’s pet industry is nearly 20%, accounting for less than 10% of the global market.

With the development and prosperity of China society, the role of pets is gradually changing — — Cats and dogs are increasingly regarded as indispensable members of the family, rather than simply companion pets. Social media has also promoted pets to become an important part of young people’s lives, and the trend of "raising cats in the cloud" has made owning pets more desirable. Therefore, the pet market has grown rapidly in the past 10 years. In 2020, the pet consumption market in China will be 72.73 billion yuan, up 21.1% year-on-year, and the CAGR will be 18.4% in 10 years.

With the development of economy, the consumption of pets is also increasing. Families in most developed countries regard pets as family members, and the spending on pets is increasing. According to Euromonitor data, in 2020, the global pet market industry scale will be about US$ 138.2 billion, up by 4.4% year-on-year, and the CAGR will be 3.6% in 10 years. Among them, the pet consumption market in China, Japan and the United States accounted for 8.1%, 4.2% and 41.1% of the global market respectively.

2. There is a big gap between China’s pet raising rate and single pet consumption amount and developed countries, and there is huge room for improvement.

In the past decade, the changing population and social structure, as well as the improvement of income and adoption rate, have become the main factors to promote the growth of pet keeping rate in China. Compared with other parts of the world, in 2019, the family pet raising rate in China was only about 17%, far lower than 67% in the United States, 62% in Australia and 44% in the United Kingdom. The pet raising rate in China is far lower than that in developed countries, and there may be several times room for improvement in the future.

Since 2016, the growth rate of China’s single pet consumption has increased year by year, mainly driven by the increase of per capita disposable income and the enhancement of pets’ kinship attributes; In 2020, the annual consumption of a single pet in China will be $59. Compared with other countries, in 2020, the consumption of single pet in Japan and the United States will be $317 and $343, respectively, and the consumption of single pet in China is still lower than that in developed countries.

3. The proportion of pet expenditure in household consumption in China has increased, and the gap with the United States has narrowed.

From 2014 to 2019, the proportion of pet expenditure in household consumption in China increased from 0.16% to 0.29%, and the proportion of pet expenditure in household consumption in the United States in 2019 was 0.52%. In 2014, the difference in the proportion of pet expenditure in household consumption between China and the United States was 3.1 times. In 2019, the difference dropped to 1.8 times.

It can be seen that there is an obvious trend of consumption upgrading in the pet market in China, which accelerates the expansion of the pet market. With the stronger willingness of consumers in China to invest in pets in the future, the pet industry has great development potential.

　　[car home Technology] powershift, in the impression of most people, is just equivalent to a swordsman with high kung fu in martial arts novels (such as seeking defeat alone? )-The evaluation we can give is: fast, fast, very fast. Moreover, this kind of transmission is direct enough and efficient enough, and it is like a master who never drags his feet … but why is it fast? Why is it efficient? What is its control principle? Is it really advanced? Want to know the answer? You don’t have to go to Baidu. car home has already opened powershift’s coat for you here-ladies and gentlemen, look for the answers you want in front of the naked transmission.

> > > Special note: 1. This paper only dissembles the DSG gearbox objectively, and does not comment on the phenomenon.

　　2. Regarding the topic of stability and fault that users are concerned about, we will explain it for you in the following follow-up articles. There is a notice at the end of the article. Please leave a message and participate in the discussion if you have any questions or faults about the dual clutch gearbox!

　　As usual, first of all, briefly introduce the protagonist of this "dedication": Volkswagen DQ200 dual-clutch gearbox-the first Volkswagen DSG gearbox made in China.

● Get familiar with DQ200 gearbox quickly? Manual gearbox? Dual clutch gearbox?

　　Before we begin, we need to form an awareness of the dual-clutch gearbox in our consciousness. If you still don’t know what the gearbox is and how the basic manual gearbox works, we have prepared the following aperitif wine for you, please taste it first.

　　After understanding the structure of the manual gearbox, it is much simpler for us to understand the dual-clutch gearbox. In principle, the dual-clutch gearbox is equivalent to the combination of two manual gearboxes, one controls the odd gear, the other controls the even gear, and the reverse gear is queued according to the situation (in the DQ200 7-speed dual-clutch gearbox, the reverse gear is regarded as a group with the even gear). Then, one set can be added to the combination of these two manual gearboxes. Hong Gong, a well-known Volkswagen engineer in the media circle, used "two manual boxes and one set of automatic dialing" to vividly compare the principle of dual-clutch gearbox. The following video will help you to understand our metaphor more intuitively, and also help you to face the various parts that will be disassembled from DQ200 more calmly.

"『DQ200 gearbox principle demonstration video-in order to save your time, it is suggested thatAfter 1 minute and 12 seconds,Start watching "

　　With regard to the origin and evolution history of the concept of "dual clutch", we also give it to you as an appetizer. Please click the link below to see the ups and downs of the dual clutch so far.

● Actual disassembly of DQ200 transmission: three modules-two "powerful" and one "calculated"

　　Metaphor is metaphor. When we really put DQ200 in front of you, you can’t really see a product that is directly combined with "two manual gearboxes and one controller". The previous section is only for everyone to understand the principle of dual-clutch gearbox.

　　Judging from the actual structure of the gearbox, the main number of members of DQ200 powershift is still "three" (of course not MT+MT+ controller …). These three modules have different division of labor, and two of them are only responsible for "hard work". They are dual clutch modules and gearbox parts, and all they have to do is to transmit power, commonly known as "force". The third part is the "source of wisdom" of the dual-clutch gearbox-the electromechanical control module, but in fact it is both mental and physical-it can be said that it is both a director and an actor. What are the specific tasks and characteristics of these three modules? We interpret it by disassembling it.

● Dual clutch module: I have a foreign ID card!

　　Let’s get to know the dual clutch module with German ID on DQ200. Since powershift took his last name, you can imagine how important this guy is.

"The dual clutch module is provided by the Luk brand of Schaeffler, Germany."

　　The dual clutch module is simply two sets of clutches+one shell. We call the clutch near one end of the engine K1 clutch, and the clutch behind it K2 clutch. The two sets of clutches K1 and K2 have their own independent driven parts (friction plate+driven plate+shock absorber+driven hub), pressing mechanism (diaphragm spring, pressure plate) and operating mechanism (only the operating arm is mentioned here).

　　The double clutch housing, the driving disc in the middle of the housing, and the butterfly diaphragm springs and pressure plates of K1 and K2 are all "best friends" of the engine, and there is no relative rotation between them. The double clutch housing is connected with the engine flywheel and rotates synchronously with the engine, and these components are called "driving parts".

　　The diaphragm spring and pressure plate which rotate together with the clutch housing play an important role. Under the lever action of the control arm, the sleeve is pressed to deform the diaphragm spring, and the resulting deformation pushes (or pulls) the pressure plate to press the friction plate. At this time, the driven plate and the aforementioned driving part become a whole. With the synchronous rotation of the engine, after the power is obtained from the clutch, the driven plate relies on the internal spline to transfer the power to the input shaft, and the power from the engine enters the gearbox.

● What you don’t know about DQ200(1)
-The working principle of the clutch is the same as that of the manual gearbox, but it works in the opposite way!

　　Speaking of butterfly diaphragm spring, I have to say that this DQ200 dry dual clutch is very interesting in control mode and principle. It is consistent with the familiar manual gearbox principle, which also relies on extrusion and friction to realize the continuous transmission of power, and also uses the lever principle to squeeze the sleeve to deform the diaphragm spring. However, the diaphragm spring works in the opposite way to the diaphragm spring in the manual transmission clutch (see the dynamic diagram above). In the single-chip clutch structure of manual transmission, when the diaphragm spring is squeezed, the clutch pressure plate will be released and the power transmission will be interrupted; In DQ200 gearbox, the function of diaphragm spring when it is squeezed is actually to press the clutch to turn on the power! To put it bluntly, the clutch of the manual gearbox is-You give an external force, it separates,The clutch of this DQ200 dual-clutch gearbox is just the opposite.You give an external force, it will engage!The "disengaging bearing" and "disengaging lever" in the traditional clutch should be renamed as "engaging" XX here. …

● Gear box: double MT combined body

　　After the power enters the gearbox from the input shaft, it will begin to travel between gears. The gear camp in the box is very easy to divide-like two sets of manual gearboxes-two input shafts and two output shafts, and then a set of parking locking mechanism and a differential to transmit power to the wheel axle are added. In this way, you will find that the dual-clutch gearbox is actually just a few more shafts than the traditional manual gearbox. As we have previewed before, the shifting principle of DQ200 and manual gearbox is completely consistent, and the shifting fork pushes the engaging gear sleeve to complete the combination or separation of gears (shifting gears).

　　The two input shafts are respectively connected with the K1 clutch and the K2 clutch, and the internal and external coupling mode is adopted. The first input shaft is equipped with a 1357th gear, and the second input shaft is equipped with a 246R gear. When the two clutches work alternately, the power can be connected between the odd gear and the even gear. Take a closer look at the input shaft, and you will find another interesting thing. On the first input shaft, the gears corresponding to the 1357th gear are independent, while the second input shaft corresponding to the 246R gear has only two gears. The 4th gear and the 6th gear share one input shaft gear, and the 2nd gear and the R gear (reverse gear) share one input shaft gear. Perhaps the purpose of this design is to ensure that the hollow second input shaft can have enough strength and ensure the gearbox.

● What you don’t know about DQ200 gearbox (2)
-What’s the difference between the "N" gear (neutral gear) of the dual clutch gearbox and the manual gearbox?

　　Many netizens want to know the difference between the "N" gear of the dual clutch gearbox and the neutral gear of the manual gearbox. Take the DQ200 gearbox we disassembled as an example. Its logic in the "N" gear is indeed different from the "neutral" of our usual manual gearbox. Simply put,The "neutral" of the dual clutch gearbox is equivalent to the state that the manual gearbox is "engaged in 1st gear and engaged"., so that the speed will be faster when the power is engaged. Moreover, in the D-range mode, when the brake is stepped on for a long time, the clutch will also be automatically disconnected, and the gear engaging sleeve is still engaged with the 1st gear.

　　In addition to various shafts and gears, the gearbox body also has a part that we can’t ignore-the parking control module, that is, the "P" gear control mechanism of our vehicle. The parking gear is integrated on the third output shaft, coaxial with the reverse gear, and it is the only gear with internal splines (synchronized with the output shaft).

　　The parking control mechanism is the only one physically connected with the gear lever on the DQ200 gearbox (all other controls are transmitted by electrical signals). When we put the gear lever into the "P" gear, the gear lever is controlled by the cable, and the connecting ball pin is pulled to make the pawl buckle the parking gear, thus locking the output shaft and achieving the purpose of parking locking.

● Electromechanical control module, with developed "six limbs" and not simple mind.

　　The hardest part of the three is naturally the electromechanical control module, which is "both output and calculation". This way of working is simply a typical "IT migrant worker".

　　From the structural point of view, its composition is not complicated. The sensor, arithmetic/control chip, hydraulic unit and actuator are just four pieces of content, which is also a simple number. The electromechanical control module relies on these components to complete the whole process of obtaining information-judgment/decision-making-execution. Among them, the hydraulic pump and pressure storage tank composed of gear pump are the source of all power for the electromechanical control module, and if human organs are used as an analogy, this is the heart.

　　We humans move through four limbs. The electromechanical control module of DQ200 has six limbs, which control the operating arms of K1 and K2 clutches respectively, and the other four limbs are used to control the shift fork. Four independent fork control levers control five forks (six gears and reverse gears are two forks sharing a fork control lever), and it is the existence of independent control levers that makes it possible to engage adjacent gears in advance.

　　The "brain" that gives action instructions to limbs is provided by Continental, Germany. This brain judges the driving state of the vehicle and the driver’s intention through the engine speed sensor, the output shaft speed sensor and the operation made by the driver on the gearbox control lever, and shares a series of information on the CANBUS bus, such as vehicle speed, wheel speed, accelerator pedal position, steering angle sensor, lateral acceleration sensor and so on, and makes a response. Sensors located at the fork and clutch actuator always remind the German brain of the clutch that the gearbox is currently working and the gear that is currently combined. At the same time, according to the oil temperature sensor and oil pressure sensor in the electromechanical control module, whether the working state of the gearbox is normal or not can be monitored in time. We can imagine that this information processing ability is hopeful to challenge the popular dual-core smart phone …

● What you don’t know about DQ200 gearbox (3)
-even without a double clutch, it can be fast!

　　The reason why the dual clutch gearbox is fast enough is not only because it is as simple as a "dual clutch module", but also largely due to its independent shift control lever. Do you know what "independence" means? This means that even if there is no double clutch, since DQ200 adopts the design that the interval gears share a joint sleeve (as mentioned above), the joint sleeves of adjacent gears can operate independently, and theoretically, "the joint sleeves of one gear can be disengaged while the joint sleeves of adjacent gears are engaged!" Do you know what is the core system of Lamborghini’s ISR gearbox (the gearbox with a shift time of 50 milliseconds)? In fact, it is a number of forks that can be controlled independently!

"The reason why Lamborghini’s ISR gearbox dares to challenge the serial gearboxes of the previous supercars.
It is also because it adopts an independently controlled shift fork.

　　(This paragraph is purely for discussion, and fans are welcome to speak enthusiastically.) The effect of this independent control is more flexible than that of the mechanical multi-fork synchronous action mode relying on the "shift drum" of the sequential gearbox, especially in the case of "trip stop" (except for odd-numbered trip stop …), while the shift drum mechanism can quickly switch between adjacent gears by relying on the servo motor with quick response, but when multiple gears are shifted up or down (for example,

● DQ200(4 you don’t know (4)
-the gearbox needs to use two kinds of oil at the same time!

　　Most automatic gearboxes and even dual-clutch gearboxes only use one kind of oil, which not only needs to realize the functions of lubrication, heat dissipation and torque transmission, but also needs to provide the hydraulic pressure required by hydraulic control components. DQ200 dual-clutch gearbox adopts independent dual-oil circuit design, and different oils are applied in the two oil circuits. In the gearbox, the gear oil of model G052171 is used, which is consistent with the gear oil used in the domestic Volkswagen MQ250 manual gearbox, while the hydraulic oil of model G004000 is used in the electromechanical control module. The two oils can better play their own functions in their independent oil circuit circulation, so that the gearbox has better low-temperature working characteristics.

　　Moreover, the total oil consumption of DQ200 is only 2.7L (1.7L of gear oil and 1L of hydraulic oil), which is nearly half of that of traditional automatic gearbox and wet dual-clutch gearbox. Needless to say, DQ200 is a maintenance-free design, even if it needs maintenance later, it has obvious advantages in cost. (It is said that the oil consumption of DQ250 wet dual clutch gearbox is more than 6L, and the total oil consumption of DQ200 is less than half.)

-What’s the difference between DQ200 (7-speed dry dual clutch) and DQ250(6-speed wet dual clutch)?

　　I believe everyone knows the most obvious difference between DQ200 and DQ250, that is, the difference between "wet and dry" clutches. DQ250 uses a wet clutch, and the control method of the clutch is completely different. DQ200 relies on hydraulic pressure to push the control arm and presses the clutch plate by the diaphragm spring, while the clutch engagement of DQ250 is completely controlled by hydraulic pressure. DQ250 designed with a wet clutch uses a single oil, because of its large consumption. Therefore, the oil tank is designed, and it has pressure oil filter, oil cooler and oil pump driven by crankshaft power, which DQ200 does not have.

　　In addition, due to the different number of forward gears, the 7-speed DQ200 has three output shafts, the reverse gear and the parking gear alone occupy one output shaft, while the DQ250 has only two, and the parking gear of DQ250 is integrated on the differential.

Summary:

　　After reading the disassembly article of DQ200, I believe everyone has a deeper understanding and cognition of this 7-speed dry dual-clutch gearbox.Personally, the dual clutch gearbox is not complicated in principle or structure, and the structure based on manual gearbox is the fundamental reason for its high transmission efficiency and low fuel consumption.The design idea of DQ200 dual oil circuit and dual oil is one of its highlights. The two independent oils have more advantages in functional adaptability, and the total oil consumption of 2.7L is also a figure worth showing off.

　　Of course, all advanced and fresh technologies always need to face people’s doubts and challenges, and our users still have various questions about "dual clutch". In the next article, we will answer the hot issues of gearbox reliability, price, maintenance and so on that are concerned by the majority of riders, and present more "DQ200 dual clutch gearbox you don’t know" for you.

Who will you meet on the last day of 2020? What do you miss? How would you sing this song in Crowd? "

Later, Wang Baoqiang forwarded this Weibo and said, "After listening to this song, I remembered the days 16 years ago, and I will always remember the companionship and encouragement my sister and Brother Hua gave me. Thank you for meeting you’. " It is reported that Wang Baoqiang met Rene Liu and Andy Lau in 2004 for filming world without thieves, in which Andy Lau played Wang Bo, Rene Liu played Wang Li and Wang Baoqiang played Silly Root. Fan comments: "Thanks for meeting, Brother Bao keeps going", "Stupid root at that time, come on".

Xinhua News Agency, Beijing, June 17 (Reporter Hou Xiaochen) Foreign Ministry spokeswoman Lu Kang confirmed on June 17 that Xiang Xiang, a giant panda cub born in Japan, will be returned to China on a delayed date by mutual agreement between China and Japan.

Lu Kang said at a regular press conference on the same day that according to the Agreement on Cooperation between china wildlife conservation association and Tokyo, Japan for Joint Research on Giant Panda Protection, Xiangxiang, a giant panda cub born in Ueno Zoo in Tokyo, should have been returned to China when it was two years old. Now, with the agreement reached and signed by China and Japan, Xiangxiang’s return to China will be delayed for one and a half years until the end of December 2020. At present, the relevant agreement has come into effect.

Lu Kang said that the giant panda is a national treasure of China and a "messenger" to promote friendly exchanges between China and foreign countries. China is very happy to see that Xiangxiang has been taken good care of and received friendly hospitality during her stay in Japan. China can feel the Japanese people’s love and reluctance to give up from every detail. Now, at the request of Japan, China agrees that Xiangxiang will stay in Japan for a longer period of time. "We also hope that this decision will enable Xiangxiang to play a better role as an ambassador of Sino-Japanese friendship."
