A synchronizer ring assembly including an internally toothed, cylindrical sleeve of high strength metal with a shifting collar of plastic material mounted on the outer surface of the metallic sleeve. The shifting collar is formed with a shifter fork slot and is interlocked with the sleeve to prevent axial displacement of the shifting collar with respect to the sleeve. In one embodiment, the shifting collar is freely rotatable with respect to the sleeve. In other embodiments, the shifting collar is secured against rotative motion with respect to the sleeve. |
