Abstract:
Clutch mechanism for a friction clutch, having a reaction plate (100), a friction disc (7), carrying friction linings (8) at its external periphery (8), said mechanism comprising a thrust plate (1), a cover (2) intended to be fixed to the thrust plate, axially acting engagement means (3) for bearing on the cover (2) and controlled by a disengagement member, acting between on the one hand the cover (2) and on the other hand the thrust plate (1) by means of an abutment member (14), the thrust plate (1) being fixed with respect to rotation to the cover (2) whilst being able to move axially with respect to it and being subjected to the action of elastic return means (9) returning the thrust plate (1) axially towards the cover (2), said clutch also having a wear take-up device comprising ramp means (11) having circumferentially disposed ramps (15) placed axially between the abutment means (14) and the thrust plate (1), the same ramp (15) being adapted to cooperate with counter-ramp means (4), characterized by the fact that there are provided stop means (20) carried by the cover (2) and adapted to limit the travel of the engagement means (3), in a storage position of the mechanism when the thrust plate does not engage a friction plate, away from the cover (2) and close to their working position.
