ABSTRACT:
A twin mass flywheel for a vehicle comprising two co-axially arranged relatively rotatable masses interconnected by a plurality of pivotal linkages. Each linkage comprises a first link pivotally connected to one flywheel mass, a second link pivotally connected to the other flywheel mass and a pivot joining the links to move radially outwardly. A resilient torque member in each common pivot operable after a predetermined rotation between the flywheel masses to resist said relative rotation. A variable hysteresis friction damping assembly, whose resistance to relative rotation changes as the relative angle of rotation is altered, acts between the flywheel masses. The damping assembly can be provided by two friction damping plates which operate at different stages of rotation. The relative rotation may be limited by a stop member on at least one of the flywheel masses which abuts an abutment surface on the other flywheel mass. The abutment surface can be resilient for cushioning abutment by the stop member.
