How Does a Continuously Variable Transmission Work?
1 Answers
The following is the working principle of a continuously variable transmission: 1. The power output from the engine's output shaft is first transmitted to the driving pulley of the CVT, then to the driven pulley via a V-shaped belt, and finally to the wheels through the reducer and differential to drive the car; 2. During operation, the movable discs of the driving and driven pulleys move axially to change the working radius where the conical surfaces of the driving and driven pulleys engage with the V-shaped belt. The axial movement of the movable discs is controlled by the driver through the system, which adjusts the pressure in the hydraulic pump cylinders of the driving and driven pulleys as needed; 3. Since the working radii of the driving and driven pulleys can be continuously adjusted, this enables continuous variable transmission.
