Abstract

A free wheel, especially for a crank CVT, which has an inner ring, an outer ring that can rotate in at least one rotary direction in relation to the inner ring and is arranged radially around the inner ring, and a plurality of clamping bodies which have a head region and a foot region. The clamping bodies are arranged between the inner ring and the outer ring and can be subjected to the radially inwardly acting elastic force of a peripheral spring engaging in a spring groove, towards the inner ring. The guidance of the clamping bodies is carried out at the same time in the head region and in the foot region, and the clamping bodies are in the form of a cycloid in the head region and the foot region.
