ABSTRACT:
Arrangement for preventing rattling caused by a synchronizing ring [(36)] for an unengaged gear in a synchronized gearbox. When the gear is not engaged, its synchronizing ring is arranged for limited rotation relative to a hub arranged non-rotatably on a shaft [(6)] and relative to a synchronizing sleeve which is movable axially on that hub. Radially acting plate spring elements [(50)] are incorporated with prestress in the arcuate space [(45)] between an outer surface [(46)] of the synchronizing ring [(36)] and an inside surface [(48)] of the ridged rim [(34)] of the synchronizing hub. The plate spring elements [(50)] cooperate with the synchronizing ring [(36)] to hold the synchronizing ring in a position of suspension relative to the synchronizing hub [(10)] and thereby prevent it being rotated between its end positions and causing rattling.
