摘要：A baulkring-type synchronizer (18) includes cone clutch friction surfaces (24,48and 26,50) and jaw clutch teeth (36b,28 and 36c,30) for frictionally synchronizing andpositive connecting gears (14,16) to a shaft (12). A plurality of rigid members (72) isdrivingly interposed between blocker teeth (44,46) affixed to baulkrings (40,42) and self-energizing ramp surfaces (71a,71b,73a,73b) on self-energizing members (70,72) mountedon an outer circumference of a hub 32 affixed to the shaft (12). A shift sleeve (34) isslidably splined to the hub (32) and is moved by an operator shift force (Fo) and anadditive force (Fa) provided by the self-energizing ramp surfaces. Both forces (Fo and Fa)react against the blocker teeth to engage the friction surfaces. The self-energizingmembers (70,72) are slidable relative to the hub and are axially centered resiliently onthe hub by detent assemblies (76,78).
