SYNCHROMESH TRANSMISSION APPARATUS

摘要

A synchromesh transmission comprises a resilient ring interposed between a sleeve mounted for axial slidable movement on a hub on a main shaft and a blocking ring provided on the outside of the sleeve. The resilient ring is arranged so that at the time of displacement of the sleeve, the resilient ring is initially pushed laterally by the sleeve so as to push the blocking ring and then the resilient ring is compressed and deflected radially by the sleeve so as to allow the sleeve to pass thereover and engage a drive gear loosely mounted on the main shaft.
