ABSTRACT:
A torque clipping mechanism embodying the concepts of the present invention is adapted to obviate torque spikes from being imparted to the transmission of a vehicle by the crankshaft of an engine during the start-up and shut-down procedures for that engine. The torque clipping mechanism operates in conjunction with a torque transfer device that is operatively connected between the crankshaft, which delivers torque from the engine, and the rotatable input shaft of a vehicular transmission. A spring is employed to effect the application of the torque transfer device, but the spring allows slippage of the torque transfer device upon the application of a pre-determined torsional force to the torque transfer device. Hydraulic fluid acting under centrifugal force is employed to preclude slippage when the rotational speed of the power output shaft exceeds a predetermined rate.
