Abstract
A pin-type, double acting synchronizer (22) with friction clutches (26,50 and 28,52), jaw clutches (30,34 and 32,36), a shift flange (42), self-energizing ramps (13b,13c,13d,13e) affixed to a shaft (12), and self-energizing ramps (45a,45b,45c,45d) affixed to a self-energizer member (44). Engagement of the ramps provides an additive axial force (F.sub.a) for increasing the engagement force of the friction clutches. The member (44) is secured for rotation with and sliding movement relative to the flange (42). Spring washers (46,48) react in opposite directions between member (44) and the jaw members (34,36) for limiting the amount of additive axial force (F.sub.a).
