A cage freewheel for installation into the clamping gap of a shaft/hub connection, in particular in an e-bike drive, includes an annular cage with, following one another in the circumferential direction, bearing rollers for mounting the hub and the shaft together, and clamping bodies arranged pivotably in the cage. The clamping bodies block a relative movement between the shaft and the hub in a frictionally locking manner in one rotational direction, and allow rotation in the other rotational direction, and are spring-loaded in the coupling direction by an annular spring which extends around the row of the clamping bodies in a slot in the radially outer surface of the clamping bodies. The bearing rollers are arranged in each case in pairs in associated pockets of the cage on both sides of the annular spring. Here, the bearing rollers are received in a positively locking manner in the associated pockets.

Cage freewheel with bearing rollers

A return stop limiting torque, particularly for conveyer systems, including an internal ring, a concentric external ring, and several retaining elements arranged in the annual gap between the rings, which allow a relative rotation between the rings in one direction, and block it in the other direction through form-fitting or frictional engagement. The external ring has friction areas at its radially extending faces, which can axially be clamped against the corresponding friction disks, with the friction disks being supported in a torque-proof fashion but at least partially axially displaceable. Here the external ring is divided into several axially adjacent partial rings, each being axially spaced from one another by an annular gap such that another friction disk is arranged respectively in this annular gap, which is supported in a torque-proof fashion but axially displaceable, and all of the partial rings and friction disks are axially clamped to each other.
