ABSTRACT:
An improved single cone servo-action synchronizer apparatus having a hub fixed for rotation to a transmission shaft and an outer blocker ring and a ratio gear concentrically disposed on the transmission shaft. The blocker ring is formed with a plurality of longitudinally extending drive tangs which project into apertures formed in the hub. The drive tangs have an angled cam edge which converges outwardly at a first acute angle. The apertures have a complimentary angled side which is adapted for sliding engagement with the drive tang cam edge upon energization of the synchronizer apparatus. This sliding engagment causes the torque capacity of the synchronizer apparatus to be increased for a given input synchronizing force.
