Abstract

A torsional vibration damper has a drive-side transmission element; a damping device having a plurality of energy accumulators; a driven-side transmission element configured to be rotationally deflected coaxial to the drive-side transmission element and which is connected to the drive-side transmission element via the damping device; and sliding elements arranged in one of the drive-side transmission element and driven-side transmission element so as to be movable in a circumferential direction. The sliding elements have: (i) circumferential projections for the energy accumulators, these circumferential projections being directed toward adjacent sliding elements, and/or (ii) penetration spaces for circumferential projections provided at the adjacent sliding element. The energy accumulators are supported at the sliding elements, the sliding elements having in sequence in an axial direction at least one circumferential projection and/or at least one penetration space at their circumferential side which faces a sliding element adjacent in the circumferential direction.
