A torsional vibration damper arrangement such that an excessive radially outward flexing of spring units is effectively prevented while torsional vibrations occurring at low torques are nevertheless sensitively damped and the corresponding spring unit is protected against overloading at the same time.

Torsional vibration damper arrangement

A hydrodynamic clutch includes a housing which can be brought into working connection with a drive; a hydrodynamic circuit formed by a pump wheel and a turbine wheel; a torsional vibration damper having a drive side transmission element, a takeoff side transmission element, and at least one energy storage group between the transmission elements; and a bridging clutch including first friction elements connected to the housing and second friction elements connected to the drive side transmission element. A first flow route extends from a first flow passage to the friction elements, and a second flow route extends from the hydrodynamic circuit to a second flow passage. A sealing arrangement cooperates with the drive side transmission element to separate the first flow route from the second flow route.
