ABSTRACT:
An assembly of free wheels in tandem has an external cylindrical sliding raceway and an internal cylindrical sliding raceway, two rows of jamming cams evenly spaced between the external and internal sliding raceways in the circumferential direction and held in the form of a ring by means of an alveolate cage, and associated lateral bearings. The assembly includes a single central bearing common to both free wheels and interposed axially between the two rows of jamming cams. The central bearing includes a radial central web in the form of a substantially planar washer, and an internal and external rim with at least one part of each rim being folded over axially so as to form a bearing surface intended to come into contact with a corresponding sliding raceways. For one bearing surface of the external rim of the central bearing extending in a given axial direction, there is a bearing surface on the internal rim extending in the opposite axial direction.
