Abstract
A frictionally engaged free-wheel clutch with an exterior ring, an interior ring approximately concentric in reference thereto, and several clamping bodies arranged in the circular gap between the interior and the exterior ring, which block a rotation of the interior ring relative to the exterior one in one direction and release it in the opposite direction. Here, it is essential that the clamping body and/or the running paths of the interior and/or the exterior ring are provided with a friction-increasing coating.
