JF011E automotive pulley kit

The main part of the continuously variable transmission is two pulleys and a metal belt composed of two pulleys. The Transmission Pulley is composed of two wheels. The groove between the two wheels is V-shaped. The wheel on one side is controlled by a hydraulic control device and can expand and contract according to the speed of the engine. The width of the V-shaped groove will also expand and contract accordingly, so that The metal strip moves up and down, which changes the radius of contact between the metal strip and the pulley, just like changing gears with different diameters during a speed change.

The CVT gearbox uses hydraulic control to change the inner diameter of the cone wheel, form pressure on the Chain And Pushbelt, and use friction to transmit power. It should be noted that the CVT gearbox transmits power through static friction. During the transmission process, the cone wheel and the steel No sliding friction is allowed between the straps.
