A torsional vibration damping arrangement for a drivetrain of a vehicle comprises a rotational mass arrangement which is rotatable around a rotational axis A and a damping arrangement fixed with respect to rotation relative to the rotational axis A. A displacer unit is operatively connected to the primary inertia element on the one side and to the secondary inertia element on the other side. The damping arrangement includes a slave cylinder with a working chamber having a volume V2, and the working chamber of the slave cylinder is operatively connected to the working chamber of the displacer unit. The damping arrangement includes a stiffness arrangement and a damper mass, and the slave cylinder of the damping arrangement is operatively connected to the damper mass by a stiffness arrangement.

A transmission includes a first shaft connected to a differential transmission by a differential carrier. The differential transmission includes a first and a second differential shaft, wherein the second differential shaft is an output shaft. A shift element that includes a sliding element is used to couple the first differential shaft to the output shaft. The sliding element is connected in a torque-proof manner to the differential carrier and is axially movable relative to the differential carrier by a spring to produce a positive-locking connection between the first differential shaft and the output shaft. The first differential shaft has a movable area that moves axially with the shift element into a positive-locking connection with an area of the output shaft. The movable area of the first differential shaft is rotatable relative to the sliding element.
