Abstract
A driving gear for all-wheel-drive vehicles, comprises a transmission provided with a plurality of shafts parallel with an axis of a vehicle. An interaxle differential gear has an axis parallel with the shafts in the transmission and adapted to output the driving force from the transmission in a divided manner. An interwheel differential gear is provided concentrically with the interaxle differential gear and adapted to apply one output therefrom in a divided manner to right and left wheels which are closer to the transmission. A bevel gear train is interposed between a driving shaft and the interaxle differential gear. The driving shaft is provided so as to cross the axes of the two differential gears at right angles thereto and apply the other output from the interaxle differential gear to right and left wheels which are more distant from the transmission. Finally, a housing is provided in which all the parts are held. The housing consists of a combination of a plurality of sections of which all of the boundary surfaces extend in parallel with one another and at right angles to the axes of the shafts in the transmission.
