How Long Can a CVT Transmission Last?
1 Answers
CVT transmissions can generally last between 300,000 to 400,000 kilometers. Here is an introduction to CVT transmissions: 1. CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, which provides excellent fuel economy, power performance, and smooth driving experience while reducing emissions and costs. 2. The principle of a CVT transmission: It mainly consists of two conical pulleys and a steel belt or chain. The two pulleys can be tightened or loosened via an electronically controlled hydraulic system, changing the diameter of the belt or chain wrapped around them, thereby altering the transmission ratio. At startup, the driving pulley has the smallest diameter, while the driven pulley has the largest diameter. During high-speed driving, the driving pulley's diameter increases, and the driven pulley's diameter decreases. The entire process of diameter adjustment is controlled by a computer, enabling seamless and continuous gear shifting. 3. Advantages of CVT transmissions: Since CVT transmissions lack mechanical gears, the driving experience is extremely smooth with almost no noticeable jerking. CVTs have fewer components, typically only a few hundred, which enhances their reliability.
