PREVENTIVE DEVICE OF RATTLING IN TIMING GEAR BOX

摘要

PROBLEM TO BE SOLVED: To provide a device very simply designed to prevent rattling caused by a synchronizing ring for an unengaged gear in a synchronized gear box and an operation mode thereof. SOLUTION: When the gear is not engaged, its synchronizing ring 36 is arranged for limited rotation relative to a synchronizing hub 10 arranged non- rotatably on a shaft and relative to a synchronizing sleeve which is movable axially on that hub 10. 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 10. The plate spring elements 50 cooperate with the synchronizing ring 36 to hold the synchronizing ring 36 in a position of suspension retative to the synchronizing hub 10, and the synchronizing ring 36 is rotated between its end positions to inhibit causing rattling.
