Abstract
A compound transmission comprising a main section connected in series with an auxiliary section is disclosed. The auxiliary section includes a splitter clutch rotatable with a main section mainshaft, and an output shaft having a splitter gear and a reduction gear rotatably mounted thereon. An auxiliary drive gear is rotatably mounted on an extension of the splitter gear. A pair of auxiliary section countershafts have first, second and third countershaft gears rotationally fixed thereto and rotatably engaged with the auxiliary drive gear, splitter gear and reduction gear, respectively. A synchronized range clutch rotatable with the output shaft has a first position for coupling the reduction gear to the output shaft to provide low range ratios, and a second position for coupling the splitter gear to the output shaft to provide high range ratios. The splitter clutch has a first position for coupling the mainshaft to the splitter gear and a second position for coupling the mainshaft to the auxiliary drive gear.
