Abstract
A vibration damper for a clutch having a built-in rotary sensitive and applied force lag control for an automotive vehicle adapted to reduce the tip-in and tip-out effects on the clutch, such as in an automotive lock-up clutch in a torque converter. The vibration damper includes a hub having radially extending fingers, and the lag control comprises friction lag plates received on each finger for generally outward radial movement relative to the hub to frictionally engage in a channel of a vibration damper housing under centrifugal force due to rotation of the assembly. The outward movement of the lag plates may be enhanced by a camming action or resilient spring between the hub finger and lag plate.
