Abstract

A torsional vibration damping arrangement particularly for the drivetrain of a vehicle, having a carrier arrangement which is rotatable around an axis of rotation, a deflection mass which is movable in circumferential direction relative to the carrier arrangement. The carrier arrangement and the deflection mass are coupled so as to be rotatable relative to one another via a plurality of radially extending, flexible restoring elements which are arranged in circumferential direction. A restoring element is deformable in each instance around a force application point which is movable in radial direction under centrifugal force and which is associated with the restoring element. A first restoring element is preloaded in a first direction in inactive position of the torsional vibration damping arrangement, and in that a second restoring element is preloaded in a second direction opposite to the first direction in the inactive position.
