CLUTCH MECHANISM FOR FRICTION CLUTCH WITH LOW DECLUTCHING FORCE

摘要

The invention concerns a clutch mechanism, in particular for motor vehicle, 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) rear surface (36) and the cover (8) base (80), resilient clutch means with axial action (4, 6) axially stressing the clutch thrust plate (3) in a direction opposite to the cover (8) base (80) and a declutching device (7) to counter at will the action of said 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), and one (4) of the Belleville washers (4, 6) is in contact at its outer periphery with the clutch thrust plate (3), while the other (6) rests at its outer periphery on the cover (8), said washers (4, 6) sloping inversely, means for transmitting the force (5) carried by the declutching device (7) being incorporated between the inner peripheral zones of the Belleville washers.
