Clutch assembly having a counter-plate (32, 38) and an axially displaceable pressure plate (36, 42) for pressing a clutch disc (24, 28) between the counter-plate and the pressure plate, a hydraulic actuating system (44), an adjusting device (70, 72) for adjusting a wear-related faulty spacing, wherein the adjusting device has a ramp ring (74, 84) that is supported via a ramp system and pretensioned in the circumferential direction with an adjusting force and a clamping spring (76, 86) for clamping the ramp ring, wherein the actuating element (34, 40) or the pressure plate is supported in the open position on the ramp ring (74, 84) and, given a sufficiently large stroke path from the open position into the closed position, butts against the clamping spring (76, 86) in order to reduce the clamping force on the ramp ring. Since the actuating element is not pivoted about a pivot point but is displaced substantially purely axially, it is possible to configure the adjusting device with only exactly one rotatable ramp ring, such that as a result of the simpler structural design and the low number of components, a cost-effective clutch assembly having wear adjustment is rendered possible. |
