Abstract
A friction clutch, particularly for a motor vehicle, including a clutch disk which can be coupled in frictional engagement with the crankshaft of an internal combustion engine and which is connected by a hub to a transmission input shaft so as to be fixed with respect to rotation relative to it and can revolve with the latter around a common axis of rotation. The clutch further includes an actuation system for engaging or disengaging the frictional engagement of the clutch disk which is arranged concentric to the transmission input shaft, and a transmission brake for reducing the rotational speed of the transmission input shaft during determined shifting processes of the transmission. The transmission brake can be controlled independent from the actuation system of the friction clutch, and all component parts of the transmission brake are integrated in the actuation system of the friction clutch.
