A free-wheel cage ring, having two annular flanged disks that extend radially and are connected to each other to form an axial intermediate space and have clamping bodies therebetween pivotally arranged in the cage ring and are biased for coupling by a spring, the clamping bodies perform, due to centrifugal force, a pivoting motion for decoupling against the spring force, and at least two guide surfaces are allocated to each clamping body in its axial extent, that engage opposite end peripheral regions of the clamping body, guide them at least in the peripheral direction, and have a break through which the clamping bodies extend to a radially inner clamping surface. The axial length of the clamping body radially inner clamping surface is equal to the total length of the clamping body. The guide surfaces are each formed integrally by recesses on opposite end faces of the flanged disks. |

1. A free-wheel cage ring, comprising two annular flanged disks (1, 2; 11, 12) that extend essentially in a radial direction and that are connected to each other and form an axial intermediate space, the flanged disks (1, 2; 11, 12) each having, on a respective facing end, a concentric collar (5) that is broken by recesses to form at least two guide surfaces facing the recesses, a plurality of clamping bodies (4; 14) that are located between the disks and arranged so that they can pivot in the cage ring and that are biased in a coupling sense by at least one leg spring (6; 16; 26; 36), the clamping bodies (4; 14) perform, under the effect of a centrifugal force, a pivoting motion acting in a decoupling sense against a spring force, wherein the guide surfaces (5c, 5d; 15) are spaced apart from inner and outer flanges of the disks, with two of the guide surfaces being allocated to each of the clamping bodies (4, 14) in an axial extent, one of the guide surfaces engages each opposite end peripheral region of each of the clamping bodies (4; 14), to guide them at least in a peripheral direction of the flanged disks (1, 2; 11, 12), and the collar has a break at least on a radially inner side through which the clamping bodies extend, an axial length of a radially inner clamping surface of each of the clamping bodies is equal to a total length of each of the clamping bodies, and the guide surfaces (5c, 5d; 15) are each formed integrally in the flanged disks by the recesses located on opposite end faces of the flanged disks (1, 2; 11, 12). |
