ABSTRACT:
A freewheel having inner and outer machine parts which are rotatable with respect to one another about an axis. One machine part has a smooth cylindrical clamping track, and the other machine part is provided on its circumferential face facing the smooth cylindrical clamping track with clamping ramps arrayed in the circumferential direction. A metallic cage has a series of profiled transverse webs positively locked for preventing rotation with respect to the other machine part. The cage has a central web section that extends parallel to the axis of the freewheel and is connected to two obliquely extending connecting web sections at the ends of the central section. Each oblique web section is connected to an outer web section which also extends parallel to the axis.
