Preliminary design of double rubber belt continuosly variable transmission (CVT)

A vehicle that is powered by an internal combustion engine (ICE) needs a transmission system to change the transmission ratio between the engine and the drive wheel for smooth and comfortable drive. Rubber belt continuous variable transmission (CVT) is commonly used in scooter with small engine. The...

The ball roller regulated the axial movement of two movable pulley sheave to shift the two rubber belt place between the sheaves, and change the belt-pulley contact radius. Changing this contact radius means changing the CVT ratio. To support the design requirement some calculation was made and CAE software was used to analyze force distribution on input shaft.
