Abstract: A twin mass flywheel assembly in the form of a twin mass flywheel (12), a clutch cover (11) attached to the flywheel, a clutch driven plate (19), a clutch pressure plate (14), and spring means (18) supported from the cover to clamp the driven plate between the flywheel and pressure plate to transmit torque through the assembly. The driven plate (19) includes a central hub portion (24) and an outer friction portion (25) supported from the hub portion via a slipping clutch which may be in the form of a tolerance ring (32) which allows relative rotation between these portions at torque levels above a predetermined torque thus protecting the assembly and associated driveline from damage due to high level but short duration torsional loading.
