ABSTRACT:
A synchronizer assembly for use in manual transmissions for automotive vehicles wherein an internally splined hub is operatively connected to a driven rotary shaft, an internally splined clutch sleeve being rotatably connected to said hub by external splines on the hub and axially slidable thereon, a shift fork engaging and actuating said sleeve, one or more blocker rings located adjacent to the sides of said hub, and one or more transmission gears at the sides of said hub beyond said blocker rings, the gears and blocker rings having peripheral teeth adapted to be engaged by the splines on said clutch sleeve, the blocker rings and gears also having cooperating conical friction surfaces, respectively, the clutch sleeve having an interior annular groove centrally located therein and facing said hub to receive a generally circular wire spring, which spring, after some initial allowable travel of the sleeve, resists movement thereof and abuts projections extending inward from either blocker ring on movement of clutch sleeve in either direction.
