Torsional vibration damper

A torsional vibration damper for a bridging clutch of a hydrodynamic clutch arrangement is provided with a drive-side transmission element and a takeoff-side transmission element, which can be deflected around a certain angle of rotation relative to the drive-side element against the action of energy storage devices, where at least one driver element with an actuating function is assigned to each energy storage device. To realize a multi-stage action of the energy storage device, at least some of these driver elements arrive in working connection with an assigned final turn of the corresponding energy storage device only after using up a predetermined clearance gap in the circumferential direction. For this purpose, at least one transmission element has openings to accommodate energy storage devices, and at least one circumferential boundary of each opening is provided as a driver element for the assigned energy storage device. In the absence of any relative rotational deflection of the transmission elements, at least one of the circumferential boundaries of some of the openings is separated from the adjacent final turn of the assigned energy storage device by a predetermined angular gap. The predetermined angular gap is used up only after the transmission elements have rotated a predetermined relative distance, at which point the corresponding circumferential boundary acts as the driver element on the adjacent final turn of the assigned energy storage device.
