Abstract
A rotary clutch assembly is provided with a clutch release group. The clutch release group comprises a stator surrounding a torque transmission shaft in driving connection with one of the rotors of the rotary clutch assembly. A first bearing ring surrounds the torque transmission shaft. A toroidal membrane member is fixed with respect to the stator and acts onto the first bearing ring so as to axially displace the first bearing ring in response to pressure variation within the membrane. A second bearing ring is mounted for common axial movement with the first bearing ring and rotatable with respect thereto. The second bearing ring acts onto a clutch disengagement member rotating around the torque transmission shaft.
