ABSTRACT:
A support is disclosed for a synchronizing ring for the synchronization of gears, in which the stops for coupling to the clutch are formed from lugs which are bonded integrally to the sprocket ring or ring-shaped core. The support is produced economically by a method of punching a flat ring and drawing it into a conical ring-shaped part with an outer radial edge, forming the part and punching an outer sprocket and lugs in the edge, bending the lugs alongside the part to form stops and stamping the tooth profile for the sprocket. The flat ring may also be punched with inwardly extending lugs which are then bent upwardly along the body to form the stops.
