ABSTRACT:
An improved multi-cone strutless synchronizer has one or more cone rings concentrically disposed intermediate an outer blocker ring and an inner exterior cone surface of a ratio gear journally supported on a speed shaft. The cone ring is formed with a plurality of longitudinally extending drive tangs projecting into an associated window of the ratio gear. Each drive tang is symmetrical about its longitudinal centerline defining a pair of back-angled cam edges diverging outwardly at an acute angle from the centerline. Each window has a side wall disposed in spaced parallel relation with an associated tang cam edge and adapted to be slidably engaged thereby upon the synchronizer sleeve being moved toward the ratio gear whereby the synchronizing torque is increased for a given synchronizer force.
