Abstract: In order to improve transmission efficiency, lightweight and reliability, a lubrication system of dual countershaft transmission with forced lubrication as the core was established. According to the lubrication principle, the overall scheme layout and detailed design of oil pump circuit are carried out to complete the analysis and calculation of forced lubrication virtual oil circuit. Through innovative experimental technology and methods, establish and implement pump output flow and pressure, forced lubrication oil injection hole, transmission lubricating oil used in the determination of the amount of discharge and experiment method, comprehensively and systematically evaluate the performance of forced lubrication system, verify the validity of the design, and analyses the experimental results, through precise lubrication, 2.4 L of lubricating oil is reduced to achieve the goal of reducing cost, weight and increasing efficiency.
