Abstract
A synchronizer of the pin type employing a friction cone on the gear to be engaged. The synchronizing ring employs pins positively drivingly engaging an axially movable dogged shifting clutch splined to the output shaft and axially engageable with the gear to be engaged. In one embodiment, the synchronizer ring has a plurality of sprag members circumferentially spaced about the ring and pivoted thereon with the radially outer surface thereof tapered to frictionally engage the friction cone upon axial force application to the ring by the shifting clutch. In another embodiment the synchronizer ring has a plurality of sprag members circumferentially spaced within the ring and pivoted thereon with the radially inner surface thereon tapered to frictionally engage the friction cone upon axial force application to the ring by the shifting clutch. In both embodiments, the sprag members are pivoted by the camming action to increase the friction forces and effect synchronization without increase in the axial force applied to the ring.
