Abstract
An improved strutless synchronizer has an annular spring interposed between an internally splined sleeve, mounted for axial sliding movement on a main shaft, and an associated blocking ring. Selected ones of the sleeve splines are formed at the extremities with radially inwardly extending teeth. Each of the teeth has a dual chamfered face portion in opposed relation with the annular spring. The blocking ring has three equally spaced lugs each formed with a transverse groove sized to axially capture the annular spring so as to allow the spring freedom to rotate in its grooves relative to the blocking ring. Each time the sleeve is moved toward meshed engagement with an associated main shaft ratio gear its spline teeth chamfered faces compress the spring at random points thereby minimizing spring wear. Also, the grooves, by positively retaining the spring, insure instant unloading of the blocking ring.
