Inner Workings Of Continuously Variable Transmission 3D Animation


CVT is Continuously Variable Transmission, and it is a type of single-speed automatic gearbox.CVT is used by the latest high performance vehicles due to the smooth driving experience it provides. In this video we will explore the inner workings of Continuously variable transmission including that of a Reverse gear.

The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.CVTs are used in automobiles, tractors, motor scooters, snowmobiles, and earthmoving equipment.The most common type of CVT uses two pulleys connected by a belt or chain, however, several other designs have also been used at times. Watch the video from Lesics for more info:

The most common type of CVT uses a V-belt which runs between two variable diameter pulleys.The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diameter of the pulley is dependent on the distance between the two-halves of the pulley.


The V-shaped cross section of the belt causes it to ride higher on one pulley and lower on the other, therefore the gear ratio is adjusted by moving the two sheaves of one pulley closer together and the two sheaves of the other pulley farther apart.
