LOCK-UP CLUTCH AND HYDROKINETIC COUPLING DEVICE COMPRISING SAME

摘要

A lock-up clutch (10) comprising a piston (12) axially movable relative to a fixed drive wall (13), friction means (14) between the piston and the drive wall (13), a driven wall (15) on the opposite side of the piston from the drive wall (13), and resilient damping means (16) acting circumferentially between the piston (12) and said driven wall (15). At least on a level with the resilient damping means (16), said driven wall (15) extends on the side of the resilient damping means (16) axially facing the piston (12) and is adjacent to said piston (12). The clutch is useful in hydrokinetic coupling devices, particularly for motor vehicles.
