（学生rt of power flows to gearbox, the other part of power flows to variable pumps, motors and other control components of hydraulic steering regulate speed system . Such turning mechanical have the average speed is not reduced and high efficiency when about the speed difference can be no class regulation, by the steering wheel can be manipulated to achieve accurate direction control, good mobility and many other advantages. An improvement of the tracked vehicle to the performance. The system design is the key to achieving double-tracked vehicle power flow in a smooth shift. It is in reference to the DongFangHong-1302 R rubber tracked tractor some of the parameters of the circumstances, focus on the mechanical-hydraulic power transfer to the system of hydraulic systems and steering control system design and the working principle, for hydraulic components of hydraulic system, such as variable pump, quantitative motors for the design, and the selection of a reasonable system of hydraulic components, to make a reasonable match between components, to enable it to achieve the best working conditions. Meanwhile in the design of hydraulic systems and manipulation of the system performance to the preliminary calculation, The results show that such a design parameter matching reasonable and can better meet the tracked vehicle to the requirements.
