Abstract
A transmission mechanism for actuating a friction clutch, which can be disengaged against a spring force and is arranged between an internal combustion engine and a manual transmission, includes two lockable elements that are movable toward one another longitudinally to automatically change the length and compensate for clutch wear. The first element consists of a spindle which is coupled to a non-rotatable component of a disengagement mechanism of the friction clutch in a rotationally fixed and axially displaceable manner and has a steep-pitch external thread. The second element consists of a nut having a steep-pitch internal thread into which the spindle can be screwed, the pitch of the steep-pitch thread being dimensioned in such a way that no self-locking can occur between the two elements.
