This paper discusses the overall mechanical-hydraulic power to the circulation system (steering) Performance Test System and the principles established test Total program, and hardware and software from the two described in detail the performance of automobile gearbox detection system components. On the automobile transmission systems integration test rig with the main component types, focusing on the mechanical hardware to open analysis of hydraulic-mechanical power transfer to the (steering) Integrated Test Bed The main structure, characteristics and working principle of this paper, the objective significance : the auto industry, Tractor industry is to develop and upgrade period, Tracked vehicles dual power transfer device can be controlled by the steering wheel in the direction of accurate control, good mobility and many other advantages, its design and manufacture, testing and maintenance performance of the urgent request. For the development of self-owned intellectual property rights, the conditions for China to the high-performance devices, the present study.
