Abstract

A composite flywheel has primary and secondary masses rotatable relative to each other against the resistance of a damper having arcuate coil springs and an abutment between neighboring end portions of such springs. The abutment can move in the circumferential direction of the masses and is preferably form-lockingly connected against loss to at least one of the springs. To this end, a portion of the abutment extends into the adjacent convolutions of the at least one spring and is engaged by such convolutions with a force which suffices to prevent unintentional separation of the at least one spring from the abutment in the axial direction of the at least one spring.
