Abstract

A torsional vibration damper, comprising at least two components which can be rotated counter to the resistance of at least one helical spring or bow spring precurved toward the rotational axis for compression of the at least one bow spring during a relative rotation among the components. The at least one bow spring is provided with support in the circumferential direction across the outside diameter thereof on a sliding shell. In order to reduce friction, the outside diameter of the at least one bow spring has a distance from the inside diameter of the sliding shell.
