Auxiliary transmission shift control system
This patent describes a system for controlling the gear selection on a compound transmission including a range gear having a LOW range and a HIGH range position and a splitter gear having a splitter ON and a splitter OFF position. It includes a range cylinder having a bore with an axially positionable range piston sealingly defining a low range chamber and a high range chamber; a shift bar connected to the range piston and extending from the range cylinder to facilitate range gear positioning; means for selectively pressurizing the low and high range chamber to respectively position the range piston and accomplish rang gear positioning in LOW range or HIGH range position; a splitter cylinder having a bore with an axially positionable splitter piston sealingly defining a splitter ON chamber and a splitter OFF chamber; a rod connected to the splitter piston and extending from the splitter cylinder to facilitate splitter gear positioning in splitter ON or splitter OFF position; and means for pressurizing the splitter ON chamber and the splitter OFF chamber to define an initial position for the splitter piston in which the splitter gear is in OFF position.
