A torsional vibration damping arrangement, in particular mass damper subassembly, having a carrier which can be driven in rotation and a damper mass rotatably deflectable with respect to the carrier against the restoring action of a substantially radially extending damper spring. The damper spring is fixedly clamped in the damper mass and is supported or supportable with respect to the carrier for transmitting circumferential force. The damper spring is clamped between clamping elements arranged at both sides of the damper spring in circumferential direction.

Torsional vibrating damping assembly, in particular mass damper unit

A torsional vibration damper has a damper mass carrier at which is received at least one damper mass movable relative to the damper mass carrier and with at least one stop. The at least one damper mass has a stop side with a geometric shaping. At least one stop is associated with the damper mass, and has an axial overlap with the at least one damper mass in extension direction of a central axis and a stop profile at its side facing the stop side of the damper mass. At least one stop receiver is associated with the least one stop for the at least one damper mass. The geometric shaping which is provided at the at least one damper mass has a first contact region operative at least substantially in radial direction and a second contact region operative at least substantially in tangential direction. The first contact region can be brought into operative connection with the stop, and the second contact region can be brought into operative connection with the stop receiver.

Torsional vibration damper

A torsional vibration damper is provided with a damper mass carrier at which is received at least one damper mass that is movable relative to the damper mass carrier and at least one stop. The at least one stop is associated with each stop side of the at least one damper mass. The at least one damper mass and the stop have an extension in extension direction of a central axis. The at least one damper mass has a plurality of damper mass elements in extension direction of the central axis, while the stop has in extension direction of the central axis a stop profile at its side facing the stop sides of the damper mass elements. The stop profile has different radial distances from the central axis in association with the damper mass elements.

A rotational vibration damper includes a primary side () and a secondary side () which is rotatable with respect to the primary side () around an axis of rotation (A) against the action of a damper element arrangement (). At least one damper element unit () of the first group () and at least one damper element unit () of the second group () are pre-loaded, and the primary side () and the secondary side () are pre-loaded in a basic relative rotation position with respect to one another. Proceeding from the basic relative rotation position of the primary side () with respect to the secondary side (), a pre-loading path (V, V') of at least one pre-loaded damper element unit () is shorter than a maximum relative rotation path of the primary side () with respect to the secondary side ().
