Abstract

A central release mechanism for a pneumatic clutch actuating device has a cylinder housing, which, about a central axis, delimits a ring-shaped pressure chamber wherein a ring-shaped piston which can be pneumatically pressurized via the pressure chamber and which is operatively connectable to a clutch is guided so as to be displaceable along the central axis. In the pressure chamber, between the ring-shaped piston and a base of the cylinder housing, a preload spring arrangement braces the ring-shaped piston and the cylinder housing apart from one another. A movement of the ring-shaped piston relative to the cylinder housing is detectable with a sensor arrangement which has a position detector and a position encoder. The preload spring arrangement has a multiplicity of distributed preload springs, angularly spaced apart from one another, about the central axis. Between the preload springs as viewed in a circumferential direction about the central axis, at least a part of the sensor arrangement is arranged in the region of the pressure chamber providing a compact construction.
