Abstract
An actively closed friction clutch actuated by a lever actuator and having an adjusting means, the lever actuator taking the form of a roller displaced radially by a spindle, which roller acts on a unilaterally suspended lever, the latter being displaced axially and acting axially on a clamping means such as a lever, lever spring or diaphragm spring. The adjusting means for compensating friction lining wear is enabled by an end stop position widened axially relative to a stop position of the lever, which end stop position is enabled by means of an engageable/disengageable stop. To distinguish the two stop positions, the force/travel characteristic line of the lever actuator is detected by the controller of the lever actuator.
