Abstract
A vibration damper 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 having a generally wedge shape that is received in a complementary notch formed in the outer surface of each hub arm of the vibration damper and will be urged outwardly by centrifugal force to slide in a channel 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.
