The service life of a CVT continuously variable transmission is generally 300,000 kilometers:
1. The main components of a CVT continuously variable transmission are two pulleys and a metal belt. The metal belt is sleeved on both sides. In a pulley, the pulley is composed of two wheel disks, and a V-shaped groove is formed between the two wheel disks. One of the wheel disks is controlled by a hydraulic control mechanism;
2. According to different engine speeds, When the separation and approach are performed, the V-shaped groove will also become wider or narrower, and the metal belt will be raised or lowered, thereby changing the diameter of the contact between the metal belt and the pulley, which is equivalent to changing blocks with different diameters when changing speed;
3. The two pulleys are adjusted in opposite directions, that is, when the groove of one pulley gradually becomes wider, the groove of the other pulley gradually becomes narrower, thereby rapidly increasing the change of the transmission ratio.
