Gear synchronizer assembly for power transmission

摘要

In a gear synchronizer assembly of the well-known type, a clutch sleeve is formed at its inner periphery with an internal radial projection, and a thrust mechanism comprises a radially contractible annular resilient member supported in place by engagement with the inner circumference of an outer cylindrical hub portion of a hub member fixed to a transmission shaft. The resilient member has an axial leg extending therefrom toward the internal radial projection of the clutch sleeve and having a radial projection which is arranged to be engaged with the internal radial projection in shifting operation of the clutch sleeve toward a spline piece integral with a change-speed gear and arranged to abut against and urge a synchronizer ring toward the spline piece upon engagement with the internal radial projection.
