ABSTRACT:
The invention so-called torque transfer case in the housing of which there are provided a torque input shaft and, mounted at a level below, a differential gear with propeller shafts extending from opposite sides thereof in parallel relationship with the torque input shaft, the torque input shaft being drivingly connected to the differential gear assembly by a range transmission box, such as a planetary gear set, and a drive train, the drive train being connected to a sun gear of the planetary gear train, the carrier of which is connected to a differential case. A ring gear meshing with planet gears may be selectively moved into engagement with the housing or the planet carrier to shift the torque transfer case between road and range gear modes.
