Abstract

A torsional vibration damping arrangement has an input-side connection component, an output-side connection component, a first torque transmission path arranged between the input-side connection component and the output-side connection component, a second torque transmission path arranged parallel to the first torque transmission path between the input-side connection component and the output-side connection component ( ), a phase shifter arrangement and a torque adjusting arrangement ( ). The phase shifter arrangement is arranged in the first torque transmission path or second torque transmission path and is configured to generate a phase shift of rotational irregularities guided via the first torque transmission path relative to rotational irregularities guided via the second torque transmission path. The torque adjusting arrangement is configured to change a torque transmission ratio between a first torque component which is transmitted via the first torque transmission path and a second torque component which is transmitted via the second torque transmission path.
