COMPOUND TRANSMISSION HAVING DOUBLE SPLITTER GEAR AUXILIARY SECTION

摘要

A compound transmission comprising a main section and and auxiliary section is disclosed. The main section provides five forward gears. The auxiliary section includes an auxiliary drive gear rotatably mounted on an input shaft, and two splitter gears rotatably mounted on an output shaft. Each of the auxiliary section gears is engaged with a corresponding auxiliary countershaft gear. A first splitter clutch rotatable with the input shaft couples either the auxiliary drive gear or the first splitter gear to the input shaft. A second splitter clutch rotatable with the output shaft couples either the first splitter gear or the second splitter gear to the output shaft. Other embodiments having an auxiliary drive gear rotationally fixed to the input shaft are also disclosed.
