The development background of Volkswagen powershift Although Volkswagen has strong strength and enjoys a worldwide reputation, it ranks among the top five cars in the world, but it is very pitiful. Twenty years ago, Volkswagen did not have its own automatic transmission. The 4AT, 6AT and 8AT transmissions used by Volkswagen are all believed by Toyota, and Volkswagen is Volkswagen. With its superb technology in the automobile industry, Volkswagen matched the Japanese Aisin transmission to its own Passat, Magotan and other models. Volkswagen is deeply loved by consumers for its strong mechanical quality, excellent driving sense, excellent stability and durability. The existence of Volkswagen has threatened Toyota's position in the world. Therefore, Aisin will limit the number of transmissions supplied to Volkswagen. As the core component of the car, Volkswagen can't find a substitute at the moment, which is also the source of Volkswagen's independent research and development of automatic transmission.
Why choose to develop DCT transmission? There are three types of automatic transmissions, AT, DCT and CVT. Among them, AT transmission has been patented by many automobile brands such as Credit Suisse, ZF, GM, Hyundai and so on, and it is unlikely that Volkswagen will want to get involved. DCT and CVT transmissions have also become the target transmissions developed by Volkswagen because of their shallow development. At that time, major automobile companies gradually realized that although AT transmission has stable performance and excellent durability, its transmission efficiency is too low.
At that time, the steel belt technology and hydraulic control technology of CVT transmission were not so mature, and CVT transmission could not bear great torque, otherwise the steel belt would easily break and slip between the steel belt and pulley. This performance of CVT transmission is very unsuitable for Volkswagen turbocharged engine. After all, Volkswagen's turbocharged engine is very explosive and the torque is very high, so Volkswagen will point to DCT transmission.
Among AT, CVT and DCT transmissions, DCT transmission has the simplest structure and the lowest cost. Powershift is different from ordinary automatic transmission. Based on manual transmission, it can realize automatic gear shifting, which has both the driving flexibility of manual transmission and the driving convenience of automatic transmission. At the same time, you can enjoy the extremely fast shift speed, which makes the power interruption time of the vehicle very short. The public also thinks that the development of DCT is relatively easy, but the public thinks it is too simple.
After the introduction of the first generation of Volkswagen DCT transmission, the phenomenon of low gear retreat and transmission jitter appeared. When there is traffic jam, the power shift is overheated, which causes the transmission to enter the overheating protection mode and the vehicle has to wait in place. The owners have no choice but to seek various ways to protect their rights, but they have never been properly solved. The public's technical mastery of powershift is flawed, which is also a common problem of powershift.
Why does Volkswagen insist on developing powershift? Maybe you will think, since Volkswagen powershift is flawed, why does Volkswagen insist on powershift getting deeper and deeper? Why not develop CVT or AT transmission in turn? This is the style of doing things in big companies.
The first point: large enterprises have huge financial support. Once a project is launched, it must be invested heavily. If you want to go back, there is no time, and competitive enterprises will not give the public this time. The second point: Volkswagen's development of DCT transmission is a conclusion after careful analysis in the early stage. If it turns to developing CVT transmission now, doesn't it mean that its previous planning is wrong? The third point: As a big enterprise, if it encounters a little setback, it will deny the previous decision and cannot break through the spirit of innovation. How do such enterprises become the top 500 in the world? Volkswagen will not reach the scale of development at this stage.
Volkswagen insists on developing DCT transmission to overcome difficulties and forge ahead. Fortunately, the China auto market has not abandoned the Volkswagen DCT. Relying on the strong domestic automobile market, Volkswagen DCT transmission has been upgraded for the first, second and third generations, and now it is quite mature. Car owners who bought Volkswagen powershift in the last three years should rarely encounter the phenomenon of overheating of Volkswagen powershift, and the shift of Volkswagen powershift is relatively smooth, and the low-speed fluctuation is almost imperceptible.
To sum up, automatic transmission is the development trend, and the public analyzes the present situation and decides to develop DCT transmission. There is no doubt that DCT transmission is flawed, but through their own efforts, Volkswagen is gradually improving DCT transmission.
