Series damper dynamic lag system.

摘要

A vibration damper (10) with a built-in self-energizing lag system adapted to reduce the tip-in and tip-out effects of automotive lock-up torque converters for an automatic transmission. The lag system comprises a friction lag plate (58) having a generally wedge shape that is received in a complementary notch (21) formed in the outer surface of each hub arm (16) of the vibration damper and will be urged outwardly by centrifugal force to slide in a channel (57) formed in the housing for the damper to offer a resistance to movement of the hub that is proportional to the centrifugal force resulting from engine rpm.
