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.
Claims7
A clutch system having at least one actively closed friction clutch with an adjusting means, a controller, and a lever actuator including a lever, wherein:
- the lever actuator is automatically controlled by the controller;
- the lever actuator acts axially, by means of a roller driven by an electric motor by means of a spindle between a radially outer and a radially inner roller stop, on the lever to actuate a clamping means of the at least one friction clutch and adjustment for wear compensation of the at least one friction clutch being effected by a clutch stroke enlarged in the opening direction of the at least one friction clutch by an engageable/disengageable stop, the engageable/disengageable stop controlling an end stop position widened relative to a non-adjusting, stop position of the at least one friction clutch and bringing about an enlarged clutch stroke;
- and,
- a distinction between the stop position and the end stop position is detected by means of differing force/travel characteristic lines of the stop and end stop positions.
