GEAR SYNCHRONIZER MECHANISM IN POWER TRANSMISSION

摘要

A gear synchronizer mechanism includes a gear member rotatable on a shaft, a hub member arranged adjacent the gear member and fixed to the shaft, and a clutch sleeve encircling an outer cylindrical portion of the hub member. The clutch sleeve is formed at its inner periphery with a plurality of circumferentially spaced radial projections axially movable in the corresponding axial grooves formed in the cylindrical portion of the hub member. A radially contractible C-letter shaped spring is supported in place by engagement with circumferentially spaced inner walls of the cylindrical portion of the hub member. The spring has an intermediate ring portion integrally formed with a plurality of circumferentially spaced axial legs extending therefrom toward the respective radial projections of the clutch sleeve, the axial legs each having a radial projection to be engaged with each of the radial projections of the clutch sleeve. The spring has a pair of end portions resiliently engaged with one of the inner walls of the cylindrical portion of the hub member to retain the axial legs in place within the respective axial grooves.
