ABSTRACT:
The free-wheel has an inner ring (30,138) and an outer ring (32,140). Generally bone-shaped clamping elements (18,116) are located between the rings (30,32; 138,140) which are provided with an outer radial thickening (24), a central waist (22,152) and an inner radial thickening (20,150). A cage ring (10, 142) that guides the clamping elements (18,116) in a synchronous manner is arranged at the height at the inner radial thickening (20,150). The cage ring (10,142) consists of two cage ring segments (34,144) that have an axial distance to each other and axial webs (38,146) that connect the same and between which pockets (14,148) for the clamping elements (18,116) are formed. The cage ring (10,142) consists of a viscoelastic plastic material, in particular an elastomer. Its webs (38,146) have such a radial thickness that generally corresponds with the inner radial thickening (20,150) of the clamping elements (18,116), at least on the side impinged on by a clamping element (18,116) during a rebound of the same ("popping") caused by an overload.
