Abstract
A freewheel, which has an inner ring, an outer ring that can be rotated relative to the inner ring in at least one rotational direction and which is disposed radially around the inner ring, a plurality of rolling bodies, which are disposed between the inner ring and the outer ring, and at least one rolling body suspension for suspending the rolling bodies in the direction of the inner ring. The rolling body suspension has a spring which overall has a circular shape and is adapted such that the rolling bodies are loaded radially inward in the radial direction of the freewheel. In a plane that is formed by the longitudinal direction and the radial direction of the freewheel, the spring has a substantially rectangular profile.
