ABSTRACT:
In a gear synchronizer, a clutch sleeve has internal splines in continual engagement with external splines of a hub member fixed to a shaft and is axially shiftable to be engaged at its internal splines with external splines of a spline piece integral with a gear member rotatable on the shaft. The gear synchronizer includes a support ring encircling the spline piece and having a radial projection axially movable in a corresponding radial recess in the spline piece, a first synchronizer ring coupled with the support ring and having an external frustoconical surface for frictional engagement with an internal frustoconical surface formed on one side of the clutch sleeve, a second synchronizer ring axially movably coupled with the first synchronizer ring for relative rotation and coupled with the support ring for rotation therewith and having an internal frustoconical surface for frictional engagement with an external frustoconical surface formed on the one side of the clutch sleeve, and an annular waved spring disposed between the synchronizer rings. When shifting, the second synchronizer ring is brought into frictional engagement with the external frustoconical surface of the clutch sleeve against the waved spring after frictional engagement of the first synchronizer ring with the internal frustoconical surface of the clutch sleeve.
