Abstract

Apparatus for damping torsional vibrations, particularly in the power train of a motor vehicle, has first and second torque transmitting devices rotatable with and relative to each other about a common axis against the opposition of a damper having springs confined in an annular chamber of one of the two devices. The extent to which the two devices can turn relative to each other is determined, at least in part, by plastic inserts which are installed in the one device radially inwardly of the chamber and have anvils which abut each other upon completion of a preselected angular displacement of the two devices relative to each other from a neutral position.
