GEAR SYNCHRONIZER FOR POWER TRANSMISSION

摘要

In a gear synchronizer assembly of the well-known type, an internal splined portion of a clutch sleeve includes first internal splines engageable with external splines of a synchronizer ring and second internal splines engageable with external splines of a spline piece. The first internal splines of the clutch sleeve are formed smaller in axial length than the second internal splines of the clutch sleeve to reduce the shift stroke of the clutch sleeve as short as possible and to avoid increase of relative rotation between the clutch sleeve and the spline piece.
