Patent ID: 8567582

Claim:
A synchronizer assembly for a transmission in a motor vehicle powertrain, the synchronizer assembly comprising: a synchronizer sleeve that engages a first gearwheel of the transmission, the synchronizer sleeve and the first gearwheel being rotatable about a shaft and the synchronizer sleeve being axially moveable along the shaft; and a synchronizer ring that selectively engages the synchronizer sleeve, the synchronizer ring including a synchronizer spring, a second gearwheel of the transmission, the second gearwheel including a plurality of splines with projections, the synchronizer spring having a first position that abuts against the projections to exert a pre-synchronization force that pushes the synchronizer ring against the synchronizer sleeve to synchronize the synchronizer ring with the synchronizer sleeve and a second position in which the synchronizer spring moves over the projections after synchronization, and a plurality of lugs that engage the second gearwheel to synchronize the rotation of the first gearwheel to the second gearwheel, and wherein the synchronizer spring is retained on the plurality of lugs.
