ABSTRACT:
A torsional vibration damper assembly providing a variable torsional spring rate in conjunction with variable damping friction torque, which includes a hub having a radial flange, a pair of intermediate drive plates carrying the friction facings and encompassing the hub flange, an outer pair of spring retainer plates axially disposed adjacent the drive plates, and damper springs received in axially aligned spring windows formed in the retainer plates, drive plates and hub flange. Rates and travel of the damper assembly to provide a multi-stage operation are accomplished by modifying the locations or sizes of the damper springs, shape of the spring windows in the various plates, stop pins and/or stop pin slots.
