Abstract

A torque transmitting unit in the power train of a motor vehicle for transmitting torque between an engine crankshaft, and a transmission having at least one input shaft with at least one friction clutch. The transmission input shaft is coupled with the crankshaft by the friction clutch, which includes friction disks on the power input and/or output sides, and that are pressed together axially along an axis of rotation of the transmission input shaft to form a frictional engagement through a plurality of disks arranged in alternating layers in the axial direction. The disks are pressed against a stop by an actuator and with an actuating bearing interposed, wherein the actuator is connected to a fixed part of the transmission housing in a rotationally fixed connection. The friction clutch is a wet clutch.
