Abstract
A readjustment device for travel-controlled wear readjustment for a friction clutch includes a spindle with a spindle nut for rotating a pressure plate relative to a counter plate via a ramp system having a ramp ring for axial displacement of the pressure plate relative to the counter plate as a function of a relative rotation. The ramp ring has a first engagement device that is connected in a positively locking manner to the spindle nut. The first engagement device is designed such that, in an assembled state, the first engagement device is detachably connected to the spindle nut. This allows an inspection of the function of the readjustment device, in particular of the ramp system, in an assembled state of the readjustment device to be performed with little expenditure of time and without the risk of damage to a component, for example to the blocking elements on the pinion.
