ABSTRACT:
The synchronizer for selectively coupling a pair of gears which are journalled on a shaft includes a coupling sleeve slidably splined on the shaft for selective engagement with the gears. A pair of synchronizer rings are provided for frictional engagement with the gears. The synchronizer rings which are formed from sheet steel stampings are provided with three axially directed combination guide pins and blocker pins which extend into three respective recesses in the guide sleeve. In one embodiment the rings are biased toward each other with the extensions on one ring overlapping the extensions on the other ring and in a second embodiment the extensions on each ring extend into opposite ends of a common member slidably mounted in the recesses in the coupling sleeve.
