More Information
Summary:The invention relates to a friction ring (1) for a synchronizing unit (2) of a variable ratio gear transmission. The friction ring (1) comprises a conical friction body having an inner friction surface and an outer installation surface which each bound the friction ring body in a radial peripheral direction extending perpendicular to an axial friction ring axis (4). The friction ring body comprises a projection (9) for restraining a movement of the friction ring (1) relative to a synchronizer ring (7) substantially along the friction axis in operation in the synchronizing unit (2).
