SYNCHRONIZER OF A GEARBOX OF A MOTOR VEHICLE AND A MOTOR VEHICLE EQUIPPED WITH SUCH A SYNCHRONIZER

摘要

Transmission synchronizer, comprising a synchronizing hub (7), a stop plate (10), a synchronizing sleeve (14), a lever-operated reverse brake system (3) (4) interposed between the hub of synchronization (7) and the abutment plate (10), being pivotably bearing on the internal face of the plate by actuating the tabs (21) of the levers (4) and resting by the ends against push-fingers ( 24) which bear against a friction ring (12). The pivot control means is formed by the synchronizing sleeve (14), and the actuating tabs (21) project radially beyond the radially inner edge of the front face (32) of the sleeve (14). and are retractable by the sleeve (14). The invention is usable in motor vehicles.
