Abstract

A divided flywheel for reducing vibrations transmitted from an engine to a power transmission line has an input and output part connected, respectively, to the engine and the transmission line. The input and output parts are coupled by coupling spring arrangement which allows for a degree of relative rotation of the parts. A plurality of attenuators (e.g., stop springs, friction linings, etc.) are arranged to take effect following selected predetermined angular displacements of the input and output parts. A preferred arrangement includes a connecting part, which is frictionally attached to one of the input and output parts and which engages the other of the parts following relative rotation by a first predetermined angular displacement, and a stop spring arrangement which is engaged following relative displacement of the parts by a second predetermined angular displacement.
