To permit use of essentially circular, disk-like engagement elements (8) in a free-wheeling clutch, which can rotate to permit one-way free-wheeling operation while interfering with relative free rotation in the other direction, a coil spring (7) with two projecting spring arms (7a, 7b) is located in a recess of a radial surface (5) formed in an opening (2) in the cage ring, and the ring as well as the engagement elements are formed additionally with first and second cooperating surface pairs (3a, 8d; 4c, 8c) located at different diametrical dimensions with respect to a pivot axis of the engagement element, the spring arms (7a, 7b) engaging against essentially radially--with respect to the pivot axis--extending transition engagement surfaces (8e, 8f) between the respective different diametrical, essentially circular surfaces of the engagement element. The larger one of the matching surfaces (8d, 3a) is undercut with respect to a diametrically extending insertion opening so that, after rotation of the elements and preliminary compression of the spring, the spring will rotate the elements, so that the matching circular surfaces fit against each other, thereby retaining the elements in position without danger of inadvertent removal or loss.

One-way clutch

A retainer ring for a freewheel clutch comprises an annular disc and a plurality of sprag-guiding clips mounted on a radial face of the annular disc in a circumferential distribution about the disc axis. Each clip extends parallel to the disc axis and holds a sprag captive. Each clip has two parallel, circumferentially spaced legs extending from the radial disc face and being parallel to the disc axis. The legs extend along opposite sides of the circumferential surface of the sprag. Each clip further has a web interconnecting the clip legs at ends thereof remote from the radial face of the annular disc. The web extends along one of the end faces of the respective sprag.
