Abstract

A torsional vibration damper for damping a vibration component of a rotational movement around an axial direction has a damper mass to carry out an oscillation to damp the vibration component, a damper mass carrier to movably guide the damper mass, and a supporting body in contact with or can enter into contact with the damper mass in at least one operating situation of the torsional vibration damper. The supporting body is connected to the damper mass carrier to drive the supporting body relative to the damper mass carrier during rotation of the torsional vibration damper, and a support structure formed together with the supporting body to radially support the supporting body under a first operating condition and to radially release the supporting body under a second operating condition which differs from the first operating condition.
