Abstract

The application discloses a freewheeling clutch which com- prises an input ring, at least three clamping elements and an output ring, the clamping elements being supported rotatably around shafts that are provided on the input ring. The clamping elements are rotatable into a freewheeling position in which the clamping elements are essentially detached from a friction surface of the output ring and a friction surface of the input ring. The clamping elements are rotatable into a predetermined first clamping position, wherein the clamping elements wedge against the friction surface of the input ring and against the friction surface of the output ring. Moreover, the clamping elements are rotatable into a predetermined second clamping position, wherein the clamping elements wedge against the friction surface of the input ring and against the friction surface of the output ring. A transmission of torque from the input ring to the output ring in the first clamping position is opposite to a transmission of torque in the second clamping position.
