Abstract

A torsional vibration damper in a gearbox housing has an input part connected to a drive and acts on a first damping unit and an intermediate part which acts as the output of the first damping unit and as the input of a second damping unit. The torsional vibration damper further has an output part which is in working connection with the second damping unit and which is designed to accept a takeoff. Takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet. A sealing wall separates the torque-transmitting space from a damping space including the first damping unit.
