ABSTRACT:
A clutch damper assembly has a friction lag device which is energized in only one direction of torque variance. During the occurrence of torque transients, a torque increase in the forward direction is resisted by the springs in the damper, while a torque decrease is absorbed by a friction lag device. The friction lag device is comprised of a wedge-shaped pads which are disposed in pockets on one portion of the clutch damper. The pads frictionally engage another portion of the clutch damper which is rotatable relative to the portion having the pockets. Relative motion in one direction releases the pads from frictional engagement while relative motion in the opposite direction urges frictional engagement.
