Abstract

A torsional vibration damper includes a common axis of rotation extending along an axial direction, an input part, an output part, rotatable relative to the input part in a limited manner with torque transmission, and a ramp system. The ramp system includes an axially displaceable component, a plurality of rolling elements for converting rotation of the input part relative to the output part into an axial shifting of the axially displaceable component, and a plurality of energy storage elements. The plurality of energy storage elements are arranged distributed along a circumferential direction, extend along the axial direction, and are elastically deformable in the axial direction.
