ABSTRACT:
A pin-type, double-acting synchronizer mechanism (20) with friction members (30, 40 and 32, 42), jaw members (34, 50 and 36, 52), three circumferentially spaced pins (44) including blocker shoulders for preventing asynchronous engagement of the jaw clutches, and pre-energizer assemblies (48) to ensure initial engagement of the friction rings and blocker shoulders in response to initial engaging movement of a shift flange (46), and self-energizing ramps (24d, 24e, 26d, 26e) defined by posts (24c, 26c) projecting from a hub (22) and self-energizing ramps (54b, 54c, 54d, 54e) defined by a ring integrally formed with the flange and two of the jaw members. The self-energizing ramps remain engaged when the jaw clutches are engaged to assist keeping the jaw clutches engaged. A modified synchronizer 120 includes springs 155 to control/limit the additive force provided by the self-energizing ramps.
