A friction clutch arrangement includes a clutch housing mounted to a flywheel, a pressure plate, a clutch disk mounted on a transmission shaft, and a diaphragm spring which loads the pressure plate toward the flywheel to engage the clutch. A disengagement device includes a sliding sleeve which is axially displaceable on the shaft to introduce a disengagement force to the clutch spring via an force action point, thereby producing a characteristic curve of disengagement force versus disengagement travel of the sleeve. During disengagement, a compensation device introduces a compensation force counter to the pressing force in a predefined section of the characteristic curve, thereby reducing the disengagement force in the predefined section. A switchable force transmission device changes the effective force transmission ratio of the pressing force and the disengagement force during disengagement in a predetermined manner, thereby optimizing the disengagement stroke of the pressure plate.
