ABSTRACT:
A pin-type, double-acting synchronizer mechanism (22) with friction clutches (24,36 and 26,38), jaw clutch (28,14b and 30,16b) and self-energizing ramps. The ramps act between a shaft (12) and a shift flange (32). The shift flange is rotatable relative to the shaft and jaw clutch members 28,30, and defines three sets of self-energizing ramps (32k,32m,32n,32p) which act against three sets of ramps (35c,35d,35e,35f) defined by elongated members (35). Members (35) are fixed against rotational and axial movement relative to the shaft. Three circumferentially spaced pins (40) include blocker shoulders (40c,40d) for preventing asynchronous engagement of the jaw clutches and pre-energizer surfaces (40e,40f) which each cooperate with a pre-energizer and neutral centering assemblies 42. The angles of the self-energizing ramps may be varied to provide substantially the same synchronizing time for several or all of the ratio gears in a multi-ratio transmission.
