A gear transmission for the final drive of a heavy automotive vehicle, such as a tracked vehicle, comprises two planar gear sets each having at least one gear rotatably supported on a respective housing part. The two housing parts are rotatable relatively about the axis of a coupling shaft to vary the interaxial spacing of input and output shafts connected to the respective sets and offset from the coupling shaft. This allows the interaxial spacing to be adjusted for various vehicle requirements without varying the transmission ratio.

A gear transmission forming a final drive in a power train of a heavy automotive vehicle, said gear transmission comprising: a first set of intermeshing gears lying in a first plane and having an input shaft connected to one gear of said first set and a coupling shaft offset from said input shaft and connected to another gear of said first set; a second set of intermeshing gears lying in a second plane parallel to said first plane and having said coupling shaft connected to one gear of said second set and an output shaft offset from said coupling shaft and connected to another gear of said second set; and a common housing for both sets of gears having a support part and first and second housing parts respectively assigned to said first and second sets and each rotatably supporting at least one gear of the respective set, at least one of said sets being a planetary standing gear set with planet gears journaled on fixed axes on the respective housing part and interposed between the said one gear and the said other gear of said sets, said housing parts being relatively displaceable angularly about the axis of the coupling shaft and duplicable relative to said support to vary an interaxial spacing of said input and output shafts without changing transmission ratio of said transmission, means being provided to affix said first and second housing parts to said support part.
