Abstract:
A clutch mechanism for friction clutches, in particular for motor vehicles, including a cover (8) with a transversely oriented back (80) and fixing means for fixing the clutch mechanism to a rotational drive flywheel, a pressure plate (3) having a front friction face (30) to co-operate with a clutch friction disc, means (9) for rotationally coupling the pressure plate (3) to the cover (8), allowing axial movement, and, disposed between the pressure plate (3) and the back (80) of the cover (8), a diaphragm (2) having an outside peripheral part (21) urging the pressure plate (8) axially away from the back (80) of the cover (8) and extended inwardly by fingers (23) to oppose selectively the action of said peripheral part (21.), an assistance spring washer (7) bearing on the cover (8) and operating on the fingers (23) of the diaphragm (2) in the clutch release direction, the mechanism being equipped with a wear compensator device (90) for compensating wear of at least the friction linings of the clutch friction disc, characterised in that the assistance washer (7) is disposed axially between the pressure plate (3) and the diaphragm (2).
