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.

Torsional vibration damper and torsional vibration damping method

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.

Rotational vibration damping assembly

A transmission includes a transmission input element, a transmission output element and a gear ratio changing system in a torque path between the transmission input element and the transmission output element. A torsional vibration damping arrangement with an input region and an output region is provided in the torque path. 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. The torsional vibration damping arrangement includes a phase shifter arrangement 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.

Torsional vibration damper assembly, in particular for the drive train of a motor vehicle

A gearwheel for a planetary gear train includes two working toothing regions arranged successively in direction of a gearwheel rotational axis (Z). A first working toothing region is arranged at a first gearwheel part, and a second working toothing region is arranged at a second gearwheel part. The two gearwheel parts are connected to one another by positive engagement and/or bonding engagement and/or frictional engagement so as to rotate together around the gearwheel rotational axis (Z) and/or against relative movement with respect to one another in direction of the gearwheel rotational axis (Z).
