Abstract

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.
