Abstract

A torsional vibration damper for a piston-equipped bridging clutch of a hydrodynamic clutch device includes a drive-side transmitting element for at least one damping unit, which is in working connection by way of a transmitting element on the power takeoff-side with a power takeoff component assigned to it, where at least one angle of rotation limiter is assigned to the damping unit. At least one projection is provided on one of the transmitting elements, this projection extending toward the other transmitting element and engaging in an assigned recess in the other transmitting element with predetermined play in the axial direction to form an angle of rotation limiter, where the recess is provided with an appropriate circumferential dimension for the projection to ensure the possibility of a predetermined relative deflection between the two transmitting elements.
