Is the CVT transmission of the Teana durable?
1 Answers
Under normal driving conditions without aggressive acceleration, the CVT transmission of the Teana generally poses no issues up to 200,000 kilometers. Here are some relevant details: 1. Principle of CVT transmission: It mainly consists of two conical pulleys and a steel belt or chain. The two conical pulleys can be tightened or loosened via electronically controlled hydraulic mechanisms, changing the diameter of the steel belt wrapped around them, thereby altering the transmission ratio. During startup, the driving pulley has the smallest diameter while the driven pulley has the largest. At high speeds, the driving pulley's diameter increases, and the driven pulley's diameter decreases. The entire diameter-changing process is continuously controlled by a computer, enabling seamless and stepless adjustment. 2. Advantages of CVT transmission: Since CVT transmissions lack mechanical gears, the driving experience is exceptionally smooth with almost no noticeable jerking. CVTs have fewer components, typically only a few hundred, which contributes to their higher reliability.
