Kind Code:
B2
Abstract:
In a gear synchronizer, a clutch sleeve (12) has internal splines in continual engagement with external splines of a hub member (11) fixed to a shaft (21) and is axially shiftable to be engaged at its internal splines with external splines of a spline piece (24) integral with a gear member (22) rotatable on the shaft. The gear synchronizer includes a support ring (13) encircling the spline piece and having a radial projection (13a) axially movable in a corresponding radial recess (24b) in the spline piece (24), a first synchronizer ring (14) coupled with the support ring and having an external conical surface (14a) for frictional engagement with an internal conical surface (12c) formed on one side of the clutch sleeve, a second synchronizer ring (15) axially movably coupled with the first synchronizer ring for relative rotation and coupled with the support ring for rotation therewith and having an internal conical surface (15a) for frictional engagement with an external conical surface (12d) formed on the one side of the clutch sleeve, and an annular waved spring (16) disposed between the synchronizer rings. In shifting operation, the second synchronizer ring (15) is brought into frictional engagement with the external conical surface (12d) of the clutch sleeve against the waved spring (16) after frictional engagement of the first synchronizer ring with the internal conical surface (12c) of the clutch sleeve.
