Clutch assembly

摘要

A clutch assembly comprises a torsional vibration damper 154 connected to a twin clutch unit 171, 172 via a toothed push-fit connection 163 between a clutch counter pressure plate 162 and a disc member 166 secured to the damper output flange 160. Permits a damper module to be pre-fixed to an engine and a clutch module to be fixed to a gearbox and the assembly completed when the gearbox is mounted to the engine. The twin clutch can be used for power shift transmission or for main and auxiliary drive. The actuator 185 may have concentric hydraulic pistons 204, 205 within a common housing and the bearing 187 transmits actuation force from the piston housing to the clutch housing to provide a closed force path within the clutch.
