Abstract

A torsional vibration damping arrangement, particularly for the drivetrain of a vehicle, includes an input region (12) to be driven in rotation around an axis of rotation (A) and an output region (20), wherein a first torque transmission path (14) and parallel thereto a second torque transmission path (16) and a coupling arrangement (18) for superposing the torques conducted via the torque transmission paths (14, 16) are provided between the input region (12) and the output region (20), wherein a phase shifter arrangement (26) is provided in the first torque transmission path (14) for generating a phase shift of rotational irregularities conducted via the first torque transmission path (14) relative to rotational irregularities conducted via the second torque transmission path (16), and wherein the coupling arrangement (18) includes a coupling lever arrangement (54; 54a).
