Abstract
A synchronizer assembly includes a synchronizer sleeve that engages a first gearwheel of the transmission. The synchronizer sleeve and the first gearwheel are rotatable about a shaft, and the synchronizer sleeve is axially moveable along the shaft. The synchronizer assembly further includes a synchronizer ring that contacts a second gearwheel of the transmission to selectively engage the synchronizer sleeve. The synchronizer ring includes a synchronizer spring that selectively abuts the second gearwheel to push the synchronizer ring against the synchronizer sleeve, and a plurality of lugs that engage the second gearwheel. The synchronizer spring is retained on the plurality of lugs.
