ABSTRACT:
A torsional oscillation damper for a combustion-engine crankshaft has a relatively light annular disk and a rigid abutment disk which are both centered on and rotatable about an axis. These two disks are spaced axially from each other but are fixed axially and rotationally together. A relatively heavy annular disk also centered on and rotatable about this axis independently of the light and abutment disks lies between these light and abutment disks. An annular soft elastomeric ring is engaged between the light and heavy disks and a ring of friction material is engaged axially with at least one spring between the heavy and the abutment disks. Thus oscillations are damped not only in the elastomeric ring but also by generation of friction between the ring of friction material and either the heavy or abutment disk that it engages.
