ABSTRACT:
A multi-stage torsional damping device utilized for a clutch driven member comprising a low-rate primary stage to eliminate transmission gear rattle occurring in the neutral transmission position, a medium-rate stage to cushion the torque transference from the low-rate primary stage to a high-rate final stage without impacting the damper parts. The primary stage and second stage are frictionless while the normal high-rate third stage provides friction damping. The device may also have harmonic damping properties to cushion out engine impulses of any differential magnitude that occur during and within its operating range.
