Abstract

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.
