ABSTRACT:
A pin-type, double-acting synchronizer mechanism (10) with friction members (34, 46 and 36, 48), jaw members (30, 38 and 32, 40) axially secured together by retainers (44), three circumferentially spaced pins (50) including blocker shoulders for preventing asynchronous engagement of the jaw clutches, and pre-energizer assemblies (52) to ensure initial engagement of the friction rings and blocker shoulders in response to initial engaging movement of a shift flange (42), and self-energizing ramps (24c, 24d, 24e, 24f) defined by posts (24b) projecting from a hub (20) and self-energizing ramps (42g, 42h, 42,k, 43m) defined by the flange. The synchronizer includes improved jaw members and improved self energizing ramps.
