Abstract: A friction clutch for a motor vehicle having a clutching friction member and clutching mechanism with a cover and a clutch thrust plate. A resilient clutch member and disengaging gear is disposed between the rear surface of the thrust plate and the cover for moving the clutch thrust plate towards the cover. The clutch is provided with a wear adjustment device, a resilient servo member and a resilient smooth engagement member. The resilient servo member is mounted outside the clutching friction member. The load pressure feature combining the load pressure features of the resilient servo member and smooth engagement member globally follows the load pressure feature of an axially operating resilient clutching member.

Abstract: A clutch mechanism, in particular for motor vehicles, comprising a cover (8) with a base (80), a clutch thrust plate (3) with front friction surface (30) co-operating with a clutch friction (2), and, set between the clutch thrust plate (3) and the cover (8) base (80), resilient clutch means with axial action (4, 6) axially stressing the clutch thrust plate in a direction opposite to the cover (8) base (80) and a declutching device (7) to counter at will the action of the resilient clutch means (4, 6): the resilient clutch means (4, 6) comprise two Belleville washers (4, 6) series-mounted between the clutch thrust plate (3) and the cover (8), the mechanism being equipped with a wear take-up device (90) for at least the clutch friction linings (2) actuated by the resilient clutch means (4, 6); the wear take-up device (90) comprises ramp means (111) arranged at its circumference and support zones (114), one (4) of the Belleville washers (4, 6) being in contact with the support zones (114), while the other (6) re
