ABSTRACT:
A pin-type, double-acting, one-way synchronizer mechanism (22) with friction clutches (24,36 and 26,38), jaw clutches (28,12c and 30,16b) and self-energizing ramps. The ramps act between a shaft (14) and a shift flange (32) which is rotataable relative to the shaft and jaw clutch members 28,30. Flange (32) includes radially inwardly extending teeth (32k) defining self-energizing ramps (32m,32n) which act against ramps (14d,14e) formed in shaft splines (14b). 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. Two of the friction clutches (36,38) each include three circumferentially spaced pins (40,41) rigidly extending therefrom and through openings (32c,32d) in the flange (32). The pins include blocker shoulders (40c,41c) which, when nonconcentrically disposed in their respective flange openings respectively engage flange blocker shoulders (32e,32f) for respectively engaging the two friction clutches (36,38) in response to initial axial engaging movement of the flange (32) and for preventing asynchronous engagement of the jaw clutches. The flange (32) carries three spring assemblies (42) which bias the pins (40,41) to the nonconcentric positions in their respective flange openings (32c,32d).
