Abstract

An adjusting device for operating a friction clutch is brought into active connection with the friction clutch via an output device driven by a drive. The output device includes a compensation device that compensates for a wear-induced position change of the pressure spring of the friction clutch by permitting a length change of the output device. For this purpose, the compensation device includes a fixing device that secures the relative positions of the components of the output device to each other. The fixing device is releasable in a predetermined operating state of the adjusting device by a control element. When released, the fixing device allows the relative movement between the components of the output device required to implement the length change of the output device.
