Abstract
In a synchronizer for vehicle gearboxes, a synchronizing ring has an external synchronizing cone which cooperates with an internal synchronizing cone on a shifting sleeve. The ring cone is made on an axial flange which extends from a radial web and is directed towards the shifting sleeve. An annular spring presses against the web and loads the synchronizing ring symmetrically.
Claims5
In a synchronizer formotor vehicle gearboxes for synchronizing the rotational speed of a gear provided with engaging teeth and rotatably mounted on a shaft and a shifting sleeve provided with corresponding engaging teeth and nonrotatably but axially displaceably mounted on the shaft, comprising a synchronizing ring arranged between the gear and the shifting sleeve, said ring having a radial web with internal teeth for engaging the engaging teeth of the gear and an axially directed flange extending from the web, the outer limiting surface of said flange forming a conical friction surface for engaging a corresponding internal frictional surface on the shifting sleeve, the synchronizing ring being loaded in the direction towards the shifting sleeve by spring means pressing against the ring;
- the improvement in which the axial flange of the synchronizing ring is directed towards the shifting sleeve, and the ring is symmetrically loaded by annular spring means arranged coaxially with the shaft and supported by the engaging teeth of the gear.
