Test Bench Of Powershift Tractor Transmission Improve

Tractor is the most important agricultural power machinery, it can work together with tilth machine, sowing machine, harvest machine and other agricultural machine as a unit and complete a variety of agricultural operations. Powershift transmission with electro?hydraulic control technology is used in tractor transmissions, it can be achieved shift without breaking the power, the power will not be cut off in the process of shifting, it can greatly improve the operating efficiency and ease of manipulation. It's widely used in the high horsepower agricultural tractors in developed country like Europe and the USA.In this dissertation, we research the function testing process according the series powershift transmission products of YTO France SAS. We design the test program and methods, complete the tests and trials of the powershift transmission in the factory to achieve the verification functions. The main contents include: The layout of the test bench, test bench location settings and each part of the distribution setting; The hydraulic oil supply system, Oil tanks, hydraulic pipe and filtration device settings; The testing process design, the main function of the test bench and the results analysis; Test electronic control system and test software systems.The main purpose is to verify the functionality and performance reliability problems of the Powershift transmission production,Improve the reliability of the production process...
