Mechanical transmission synchronization device for motor vehicle, has tapered ring interposed between jaw clutching coupling sleeve and transmission gearwheel, and linked in rotation with sleeve by imitation

摘要

The device has a tapered ring (10) interposed between a jaw clutching coupling sleeve (3) and a transmission gearwheel (1,2), and linked in rotation with the sleeve by a imitation (11). The imitation brings the ring in contact on a tapered axle end (13) of a cylindrical wall by friction during displacement of the sleeve. The wall is integrated to a lateral face of the gear wheel around a jaw clutch (5).
