Honda's CVT gearbox and Toyota's CVT gearbox have been recalled in large numbers, even in Japan. Honda's CVT is a typical example. The fault of the recall of 20 1 5165438+10/3 is, "If the accelerator is released during deceleration and the gear is changed from 2nd gear to1gear through paddle shifting, the drive shaft pulley of the gearbox will bear high load. In the worst case, the belt is likely to break and it is impossible to drive. " About 10.5 million sets of "NBOX" series and "none" will be recalled. On June 3, 20 13, 13 also said: "If you suddenly step on the accelerator immediately after moving the gear lever to the forward or backward position, the belt will break in the worst case, and more than 380,000" NBOX "and" NONE "will be recalled. Toyota's Daihatsu recalled about 765,000 cars of the same type, such as Move and Tanto, in February 2065,438+03. However, times have changed. Honda and Toyota are two automobile manufacturers that use CVT gearboxes more, and their technologies are constantly developing. These years are basically in a stable period. The reliability of Honda CVT and Toyota CVT depends on which of the two CVT gearboxes is reliable Personal feeling is a level, because to put it bluntly, these technologies are enjoyed by many manufacturers, especially Japan. Honda's advantage is material research and improvement, because Honda's research on CVT gearbox seems to be going it alone. Toyota's advantage lies in R&; D and design, behind which is the powerful Aisin Group. Honda CVT has stepless speed change, and Toyota adopts analog gear technology. It must be said that Honda's engine is better equipped with CVT gearbox, which makes full use of the technology of precise engine control, making driving smoother and fuel economy better. Toyota CVT gearbox controls the torque output very accurately to a certain extent. For example, Corolla will have a high torque even in a small turn to ensure the smooth running of the vehicle. This is why many people think that this car sometimes has high fuel consumption. Compared with the two, each has its own characteristics. To say whose company has the best quality, it is similar after so many years of market test. The inherent weakness of CVT gearbox CVT gearbox is most afraid of overload because of its structural characteristics. Unlike AT gearbox, it will not shift gears under overload. Even in the "manual mode", even if the user makes unreasonable operation, it will not operate unless the computer determines that it can shift gears. But the CVT gearbox is controlled by software, and there will always be "mistakes". In many cases, software control can't accurately calculate the load weight, which leads to belt slippage, and CVT belt fracture is caused by overload. CVT not only has high quality, but also software control is very important. However, high torque output is a fatal defect. If there is a high demand for automobile performance, it is suggested to avoid CVT gearbox as much as possible, especially SUV models and engines with a displacement of more than 2.0.
