ABSTRACT:
Apparatus for damping vibrations between the crankshaft of the engine and the clutch plate of the friction clutch of a motor vehicle has a first flywheel which is driven by the crankshaft, a second flywheel which is rotatable relative to the first flywheel and can rotate the clutch plate, and a torque transmitting unit between the flywheels. The unit employs one or more dampers in an annular chamber of the first flywheel and a slip clutch on the other flywheel. The output element of the damper or dampers is a flange-like device which constitutes a diaphragm spring and transmits torque to an axially stressed resilent disc which forms part of the slip clutch. The disc is riveted to the second flywheel and is adjacent an axially stressed resilient diaphragm seal which engages the first flywheel to seal the chamber from the atmosphere.
