Freewheel and freewheel arrangement

The present invention relates to a freewheel (4) having an inner ring (38), an outer ring (40) and at least one wedging element (48) between the inner ring (38) and the outer ring (40), which can be moved from a wedging position, in which the wedging element (48) prevents rotation of the outer ring (40) relative to the inner ring (38) in a first circumferential direction (24), into a release position, in which the outer ring (40) can be rotated in an opposite, second circumferential direction (26) relative to the inner ring (38), wherein the wedging element (48) is preloaded into the wedging position by means of a spring element (64). The spring element (64) has an elongate spring body (66), which extends in a radial plane and has a corrugated profile in the radial direction (20, 22). The present invention furthermore relates to a freewheel arrangement (2) having a freewheel (4) of this kind.
