<p>The invention relates to a friction clutch having: a counter-pressure plate and a cover connected thereto; a pressing plate connected for conjoint rotation to the cover by means of leaf springs and movable axially with respect to the counter-pressure plate against the force of the leaf springs; a disc spring that loads the pressing plate with a closing force against the counter-pressure plate at an operating point with the friction clutch engaged and which is supported on the cover and is actuated with a disengagement force during actuation of the friction clutch, overcoming the closing force, on plate spring tongues axially along a disengagement path; a clutch disc with wear-prone friction linings that can be tensioned between counter-pressure plate and pressing plate; and an adjusting device compensating for the wear, with a sensor spring that is arranged between cover and disc spring which yields axially depending on a disengaging force which increases based on wear and releases an adjusting ring, pre-tensioned in the circumferential direction on the opposing side, of a ramp system arranged between disc spring and cover for compensating a stop on the disc spring to be adjusted on the basis of wear. In order to ensure there is no undesired adjustment of the friction clutch for large disengagement paths and to achieve an excess travel relative to a maximum disengagement path of an undesired adjustment, a sensor spring force of the sensor spring acting against the disc spring is provided so as to increase across the disengagement path.</p> |
