Abstract

A continuously variable transmission system comprises a continuously variable transmission having two pulley sets each with two discs defining a V-shaped groove, drive means-for varying the width of said groove and a belt extending between said-pulley sets in the grooves thereof, as well as a forward-reverse control connected to the shaft of one of the pulley sets and a clutch connected to said forward-reverse control, said pulley sets, forward-reverse control and clutch each being provided with a respective actuator. The actuators of the forward-reverse control and of the clutch are of an electromechanical type.
