Abstract

A long travel damper having variable friction lag comprising a torque input cover plate and a torque output driven plate, a plurality of springs arranged on a circular spring guide for cushioning torque delivery between the cover plate and the driven plate, the springs having a large L/D ratio, and a friction lag clutch adapted to be actuated by cam plates connected respectively to the cover plate and the driven plate whereby the clutch is applied with a variable force that depends upon relative angular displacement of the cam plates.
