摘要： An extended range splitter type compound transmission (10) comprising a main transmission section (12) connected in series with a splitter type auxiliary transmission section (14) connected in series with an extended range section (15) is provided. The extended range section includes a sleeve shaft (200) fixed for rotation with the auxiliary section output gear (112) and coaxial and independently rotatable relative to the mainshaft (28) and the output shaft (74). A range section output shaft gear (202) is constantly meshed with a range section countershaft gear (204) fixed for rotation with the auxiliary section countershaft (78, 80). A range section clutch (206) has a first selectable position for rotationally coupling the sleeve shaft (200) to the output shaft (74), a second selectable position allowing independent rotation between the sleeve shaft (200), the output shaft (74) and the range section output shaft gear (202), and a third selectable position for rotationally coupling the range section output shaft gear to the output shaft and allowing independent rotation of the sleeve shaft (200).

摘要： A control for an extended range splitter type compound transmission (10) comprising a main transmission section (12) connected in series with a splitter type auxiliary transmission section (14) connected in series with an extended range section (15) is provided. The main section shift lever (72) has a first (1) and a second (1E) position for selection of low ratio (50). Selection of the second position (1E) will automatically cause the extended range section clutch (206) to be shifted to the speed reduction position thereof.
