ABSTRACT:
A torsional damping mechanism (22) adapted to be disposed between an engine (10) and a transmission (12) operative to drive ground wheels (16) of a vehicle. The mechanism includes a viscous damping device (30), an idle rattle assembly (32), a torque transmitting torsion spring bar (28) disposed in series with the idle rattle assembly and in parallel with the viscous damping device, and a mechanical friction assembly for connecting the mechanism to the engine. Mechanism (22) is structurally configured to have a low inertia. The viscous damping device includes lost motion means (48k, 50c) which allows attenuation of low amplitude torsionals without damping.
