Abstract
An improved dual-cone synchronizer apparatus having a middle cone ring concentrically disposed intermediate an outer blocker ring and an inner cone ring on a transmission shaft. The inner cone ring is formed with a plurality of longitudinally extending drive tangs projecting into an associated window formed on a flange portion of the blocker ring. Each drive tang defines a back-angled cam edge diverging outwardly at a first acute angle. Each window has a side wall disposed in spaced relation with its associated drive tang cam edge and adapted to be slidably engaged therewith upon energization of the synchronizer whereby the synchronizing torque is increased for a given input synchronizing force.
