A torsional vibration damper arrangement including a torsional vibration damper with a primary side and a secondary side rotatable with respect to the primary side around an axis of rotation against the action of a damper spring arrangement. One side of the primary side and secondary side includes two cover disk elements and a central disk element arranged between the cover disk elements. The cover disk elements are connected to one another by first connection elements radially inside the damper spring arrangement so as to be fixed axially and so as to transmit torque. The cover disk elements are connected to one another by second connection elements in such a way that they are prevented from moving axially away from one another. No torque can be transmitted between the cover disk elements by the second connection elements.

Torsional vibration damping arrangement, particularly for the power train of a vehicle

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.

A hydrodynamic clutch device used to establish and to release a working connection between a drive and a takeoff is disclosed. The device includes a housing capable of rotating around an axis of rotation, the housing containing a torus space, which forms a torus volume (TV) with a pump wheel and a turbine wheel, and a clutch space, which forms the boundaries of the clutch volume (CV) and which encloses a mechanical transmission circuit including a bridging clutch designed with a torsional vibration clamper. During the course of the minimum resting phase of the housing, the fluid which is distributed throughout the housing during the operating state decreases from a total volume comprising at least the torus volume (TV) and the clutch volume (CV) to a resting volume (RV), which is located at least essentially underneath the axis of rotation as a result of the force of gravity. A volume reduction arrangement is provided to the housing to reduce the clutch volume (CV) versus the resting volume (RV).
