TORSIONAL VIBRATION DAMPER ARRANGEMENT

摘要

A torsional vibration damper arrangement, especially for the drive train of a vehicle, comprises a primary side (12) and a secondary side (24) coupled to the primary side (12) via a damper fluid arrangement to rotate about a rotational axis (A) and to rotate relative to each other. The damper fluid arrangement comprises a first damper fluid of low compressibility, accommodated in a first damper fluid chamber arrangement (36), which transmits a torque between the primary side (12) and the secondary side (24), and a second damper fluid of higher compressibility, accommodated in a second damper fluid chamber arrangement (76), which is loaded when the pressure of the first damper fluid in the first damper fluid chamber arrangement (36) is increased. The second damper fluid chamber arrangement (76) comprises a plurality of preferably cylindrical chamber units (46) that is arranged radially outside and/or radially inside in relation to the first damper fluid chamber arrangement (36) and one after the other in the circumferential direction, a separating element (48) being associated with every chamber unit (46) and separating the first damper fluid from the second damper fluid and being displaced substantially radially when the pressure in the chamber unit (46) changes.
