Kind Code:
Y2
Abstract:
In a gear synchronizer assembly of the well-known type, a clutch sleeve is formed at its inner periphery with at least one first internal radial projection of large width and a pair of circumferentially spaced second internal radial projections of small width arranged at opposite sides of the first internal radial projection, a synchronizer ring being formed thereon with a pair of raised portions to be engaged with the first internal radial projection and another pair of raised portions to be engaged with the second internal radial projections. A thrust mechanism comprising a radially contractible annular spring is supported in place by engagement with the inner circumference of a cylindrical hub portion of a hub member fixed to a transmission shaft. The annular spring has an axial leg extending therefrom toward the first internal radial projection, and having a radial projection which is arranged to be engaged with the first 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 the synchronizer ring toward the spline piece upon engagement with the first internal radial projection.
