ABSTRACT:
A track laying vehicle has a drive motor, a transmission including a gear box, a transmission differential gear, and a pair of tracks; all of which are drivingly interconnected. The vehicle includes direction control means for controlling the relative speeds of half shafts of the differential gear. The direction control means comprises a control differential gear, half shafts which are drivingly connected to the half shafts of the transmission differential; a hydraulic, axial piston, variable displacement pump having inputs/outputs, a hydraulic, axial piston, variable or fixed displacement motor having inputs/outputs. The inputs/outputs of the pump and motor are respectively communicated. The motor is drivingly connected to an input gear of the control differential gear. One each of the half shafts of the transmission and control differentials are interconnected for opposed rotation at a specific speed ratio. The other half shafts are interconnected for rotation in the same direction at said specific speed ratio. Interconnection of the respective half shafts are upstream of final epicyclic reduction gears.
