ABSTRACT:
A torsional vibration damping mechanism (30) is disclosed in a clutch plate assembly (24) for a vehicle driveline. Mechanism (30) includes a set (36) of relative high rate helical compression springs 62, 64 for transmitting torque and alternating torsionals when a transmission input shaft (22) is connected to a load, a set (38) of relatively low rate helical compression springs (66) connected in series with spring set (36) and for attenuating torsionals when the shaft (22) is not connected to a load, and a viscous damper module (48) disposed in parallel with both spring sets (36, 38) and operative to dampen recoil of both spring sets. The viscous damper module is readily fitted to known clutch plate assemblies in lieu of mechanical friction dampers previously employed to dampen recoil of the helical compression springs in such assemblies.
