ABSTRACT:
In an automotive synchronizing clutch for a multiple speed transmission, a synchronizer sleeve is slidable axially on a system of spline teeth formed on the outer surface of the synchronizer hub. Internal teeth formed on the sleeve are brought into engagement first with locking teeth formed on a synchronizing ring and subsequently with locking teeth formed integrally with the gear wheel that is connected through the synchronizer to a shaft. The ends of the teeth on the sleeve includes recesses into which are seated the clutch teeth of the gear wheel. The synchronizer sleeve is formed with one group of holding teeth formed with recesses on both lateral flanks and another group of guide teeth which have recesses on one lateral flank and a planar surface on the opposite lateral flank. The guide teeth are narrower than the holding teeth and provide on their flanks a surface on which the locking teeth can slide to prevent the locking teeth from becoming seated in the recesses of the holding teeth and to permit the clutch teeth from becoming seated in the recesses of the holding teeth.
