Abstract:
A damper assembly has a torque input member configured to be connected to engine crankshaft through a torque limit clutch. An output member has a hub configured to be mounted to a transmission input shaft. Damping springs operatively interconnects the input member and output member, enabling the input member and output member to rotate relative to each other at some angular displacements before the input torque from engine crankshaft is completely transmitted to transmission input shaft. The damping springs includes a series of long springs and a series of relatively short spring. The long springs compress before the short compress as the input member rotates relative to the output member.
