Abstract
A differential transmission incorporating a range gear box in the housing of which a first output shaft as well as a second output shaft disposed coaxially therewith are driven by an input shaft. To reduce the number of structural components, cost, size and weight, and to obtain optimum and easily variable ratios of gear diameters, the transmission is provided with a single planetary gear train the ring gear of which is drivingly connected to an input shaft. The planet carrier is drivingly connected to a first output shaft and is provided with pairs of meshing planet gears, one gear of each pair meshing with a sun gear which is selectively connectible with the planet carrier and/or a second output shaft, and with a second ring gear which is surrounding all the gears meshing with the sun gear and which is connectible with the housing.
