says that AT gearboxes are the best, so why are they abandoned by many car companies? Is it really because of technical reasons? When they learn that you are going to buy a car, many people who know about cars will tell you not to buy dual-clutch gearboxes. AT gearboxes are more useful than dual-clutch gearboxes, but now such a trend has emerged in the car market. Many vehicles have abandoned AT gearboxes and switched to CVT continuously variable gearboxes. Take Changan Yidong plus as an example. In addition to AT gearboxes, other types of gearboxes are used. Today I will use Let’s analyze the reasons why those car companies don’t use AT gearboxes.
The first one is the reason for competition. The two best-selling cars in our country are Japanese and German cars. At the beginning, the gearbox used by Volkswagen was also an AT gearbox. But the best gearbox at the time was Aisin. Aisin is a Japanese company. Toyota holds a certain percentage of Aisin’s shares. The German Volkswagen is obviously at a disadvantage when purchasing from Aisin. After the gearbox technology, German cars gave up using Aisin's AT gearbox.
The second is the match between At gearbox and vehicle engine. The technical strength and advantages of AT gearbox are unquestionable, but there is a good saying, the most suitable is the best, love It’s not particularly suitable to match the transmission of Aisin with some car series. There is often some frustration, which brings us very poor driving experience. In order to improve the driving experience of customers, some car companies have also given up using Aisin The AT gearbox uses other gearboxes.
The third reason is technical problems. Now the two countries with more mature AT gearbox technology are Japan and Germany. These two countries have two gearbox manufacturers, Aisin and ZF. We If some domestic self-owned brands want to use AT gearboxes, they can only develop their own gearboxes, or they have to pay high patent fees. Now it is too late to develop AT gearboxes independently, but the patent expenditure is also not The cost is small, so many domestic brands can only use some other gearboxes.
The fourth reason is the production cost.Although AT's gearbox is easy to use, the production cost is relatively high, which will also stretch the sales price of the entire model. If the sales price is relatively high, there is no advantage in the current fierce market competition, so In order to reduce prices, those companies will use some CVT continuously variable gearboxes or dual-clutch gearboxes with relatively low manufacturing costs.
The current CVT continuously variable transmission has become the first choice of many car companies. Although it is still inferior to the AT transmission in some aspects, the utilization rate of the CVT continuously variable transmission has become When it gets higher, many hot-selling models say that the gearboxes used are all CVTs. CVT gearboxes have the advantages of relatively low manufacturing costs and good overall performance, and are welcomed by many car companies.
And compared to AT gearboxes, the technical requirements of CVT continuously variable gearboxes are relatively low. Many companies can develop independently, which also speeds up the decline of AT gearboxes. When you buy a car What type of gearbox is generally used?
