Abstract
A torsional vibration damping arrangement comprises an input region to be driven in rotation around an axis of rotation and an output region and a first torque transmission path and parallel thereto a second torque transmission path, both of which proceed from the input region, and a coupling arrangement for superposing the torques conducted via the torque transmission paths, which coupling arrangement communicates with the output region, a phase shifter arrangement for the first torque transmission path for generating a phase shift of rotational irregularities conducted via the first torque transmission path relative to rotational irregularities conducted via the second torque transmission path, and a pendulum mass in the phase shifter arrangement and/or in the coupling arrangement.
