Abstract
A pin-type, double-acting synchronizer and gear assembly (10) with friction rings (26, 46 and 28, 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 (20a-20d and 62a-62d). The assembly (10) includes improved jaw members and self energizing ramps, an improved shift flange, improved pre-energizers, and improved jaw member retainers. A second synchronizer and gear assembly embodiment (110) includes the above improvements plus an over stress reduction of splines 112g, 140 when gear 116 is connected to shaft 112.
