TORSIONAL VIBRATION DAMPING ARRANGEMENT FOR THE DRIVE TRAIN OF A MOTOR VEHICLE

The invention relates to a torsional vibration damping arrangement (10) for the drive train of a motor vehicle, comprising an input zone (50) to be actuated for rotation about a rotational axis (A), and an output zone (55) and a first torque transmission path (47), and a second torque transmission path (48) parallel thereto, both of which originate in the input zone (50), and a coupling arrangement (41) connected to the output zone (55) for superimposing torques conducted via the two torque transmission paths (47; 48). The coupling arrangement (41) comprises a planetary gear (61) having a planetary wheel carrier (9), a planetary wheel bolt (11), a planetary wheel element (46), an output element (85), and an output flange element (75) that is connected to the output element (85) in a rotationally fixed manner. The invention further comprises a phase-shifter arrangement (43) for the first torque-transmission path (47) for generating a phase shift of rotational irregularities transmitted via the first torque transmission path (47) with respect to the rotational irregularities transmitted via the second torque transmission path (48), and a wet chamber (63) enclosing the coupling arrangement (41) and the phase shifter arrangement (43), and comprising a flange element (70) arranged concentrically to the axis of rotation A and located radially outside of a fastening diameter (19) of a fastening element (16) on a drive unit (60) and is positioned radially inside the planetary gear (61), further comprising a cover element (22), which spatially delimits the torsional vibration damping arrangement (10) in an axial direction to the output zone (55). The wet chamber (63) is sealed with respect to a surrounding area (69) by means of a first sealing element (24) and a second sealing element (25), wherein the first sealing element (24) and the second sealing element (25) are structurally identical.
