Abstract
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.
