CVT gearbox is fuel-efficient and cheap, why don't domestic cars like to use it? There is a simple reason.

When people buy a car, gearbox is also a point to pay attention to, and gearbox, as one of the three major parts of a car, is also a very important part. There are also many kinds of gearboxes. Different types of gearboxes have different characteristics and bring different feelings to the owners, so gearboxes still need to be carefully selected. It has been found that CVT gearboxes are rarely used in domestic cars.

In fact, domestic cars still have CVT gearboxes for vehicles, such as Geely and Chery. But apart from them, CVT gearbox seems to be really unpopular. Japanese cars occupy a large part of the domestic market. Japanese cars like to use CVT gearbox, which is characterized by fuel economy. So why don't domestic cars like to use it? Insider: The reason is simple.

There are two main reasons why domestic cars don't like CVT gearboxes. The first is because of cost, and the second is because of technology.

At first, German cars used CVT gearbox, but because CVT gearbox could not bear large torque, German cars gave up CVT gearbox. However, many enterprises still haven't given up CVT gearboxes, and they have been constantly optimizing CVT gearboxes. One of the problems that cannot be avoided is patent rights. Their patents are held by Bosch (steel strip) and schaffer (steel chain) respectively. Although car companies want to buy it, they have to scrape a sum of money from their own hands, which makes many car companies reluctant to do it.

In addition to the patent fee, the torque that CVT gearbox can bear is also a problem. In order to withstand large torque, in addition to buying a more optimized CVT gearbox, we can only develop it ourselves. In this way, you need to spend more money, which is not worthwhile. Japanese cars have been deeply cultivated on CVT for a long time, and technical barriers basically do not exist, so Japanese cars can always use CVT gearboxes.

Need more funds, research and development is very difficult. The most important thing is that other gearboxes in China are more popular, and the failure rate of CVT gearboxes is still very high. Therefore, after careful consideration, most domestic cars still choose AT and dual clutch.
