Abstract

A torsional vibration damping arrangement includes an input region to be driven in rotation around an axis of rotation and an output region. A first torque transmission path and parallel thereto a second torque transmission path and a coupling arrangement for superposing the torques transmitted via the torque transmission paths are provided between the input region and the output region. A first phase shifter arrangement is provided in the first torque transmission path for generating a phase shift of rotational irregularities transmitted via the first torque transmission path relative to rotational irregularities transmitted via the second torque transmission path.
