How many years can the CVT transmission of Emgrand generally last?

Emgrand's CVT transmission can generally last for about 15 years. Structure of CVT transmission: Compared to the complex traditional planetary gear set AT transmission, the structure of CVT is relatively simpler. Taking the most common steel belt-type CVT as an example, its core components that achieve variable transmission ratios are two cone pulleys and a steel belt. The low gear of CVT is when the small-diameter driving pulley drives the large-diameter driven pulley. As the gear increases, the diameter of the driving pulley becomes larger, and the driven pulley becomes smaller. In actual working conditions, according to changes in torque and output power, the cone pulley set changes relatively under the control of the computer and its hydraulic cylinder according to a predetermined pattern: when the vehicle needs greater torque, a large reduction ratio is required, the driving cone pulley set separates to both sides to form a smaller working circle, and the driven pulley is squeezed towards the middle to form a larger working circle; when the vehicle needs less torque, the opposite occurs. Advantages of CVT transmission: In addition to the comfort advantages brought by the absence of gear shocks, since the driver can keep the engine speed within a relatively economical range by controlling the accelerator pedal during driving, and only rely on the change of the internal transmission ratio of the CVT to increase the vehicle speed to achieve economical driving, this is also the best operating mode of CVT.
