A clutch comprises at least one friction disk and clutch plates adapted to clamp the friction disk(s). Elastic means act on at least one of the clutch plates and urge the clutch plates together to clamp the friction disk(s) and thereby engage the clutch. Clutch release control means comprising a pedal are adapted to unclamp the friction disk(s) and thereby release the clutch. Assistance means for the pedal cooperate with a combination comprising at least first and second mobile members each of which is adapted to move along a respective path at the same time as the other of the first and second mobile members, proportionately to movement of the movement transmission means interconnecting the first and second mobile members. The assistance means cooperate with the combination of mobile members, are disposed between the first and second mobile members and are operative on the control means according to a predetermined law as function of the simultaneous but non-identical movements of the first and second mobile members.

Assisted clutch

A clutch comprises a casing to which is attached an intermediate member on which is mounted a rotary motor. The outside surface of an axial cartridge on the intermediate member supports and guides an axially mobile actuator. Inside a housing in the cartridge is a screw-and-nut transmission of which either the screw or the nut rotates with the motor while the other is coupled axially to the actuator.
