Abstract
A vehicle transmission couples a planetary type reduction section and a multi range speed section by means of a directional drive section. The planetary reduction section provides two underway speed ranges for each speed and direction combination selected in the multi range speed section and directional drive section. The two speed ranges available in the planetary reduction section are obtained through a rotating clutch selectively operable to engage the planet carrier with the input shaft to drive an output sun gear interconnected with the directional drive section, and a brake to stop rotation of the planet carrier relative the input shaft to allow the output sun gear to be driven by planet gears mounted on the planet carrier. Coaxial arrangement of the directional drive section about the input shaft permits direct drive of a power takeoff coupling mounted on the input shaft and further allows mounting of an accessory drive gear on the input shaft.
