Abstract
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.
