ABSTRACT:
A pin-type, double-acting synchronizer (10) with friction rings (22, 36 and 24, 38), jaw members (30, 26, 28), three circumferentially spaced pins (40) including blocker shoulders for preventing asynchronous engagement of the jaw members, pre-energizer assemblies (42) to ensure initial engagement of the friction rings and blocker shoulders in response to initial engaging movement of a shift flange (32), and self-energizing cams (32f, 32g, 20e, 20f) producing an additive axial force (F.sub.a) in response to either of the cams (32f, 32g) moving a link (48) radially inward against either of the cams (20e, 20f). The synchronizer may include springs (50) to limit the additive axial force (F.sub.a) and curved ramps (20e', 20f') to vary the additive axial force (F.sub.a).
