[0002] With the development of the automobile industry, the requirements for active safety of automobile driving are becoming higher and higher. The different experimental and testing methods of mechanical transmission products have put forward higher requirements. Dynamic test benches are the basic means of studying various failure modes of mechanical transmission and measuring their load-bearing capacity, transmission efficiency and related performance by experimental methods. For a long time, the development of transmission test benches in my country has basically remained at the level of traditional manual methods. The main types are open test benches for mechanical power flow loaded by mechanical force or hydraulic pressure, closed test benches for mechanical power flow, and closed test benches for electric power flow with generators as loads. These test benches have their own characteristics due to energy saving or loading.

[0003] However, they all have a common disadvantage, that is, the low degree of automation, it is difficult to conduct experiments according to the pre-designed test process, and it is impossible to simulate actual working conditions to test various mechanical transmission products. Therefore, the test results are always quite different from the actual situation, which greatly affects the guiding role of test data in the design and production of mechanical transmission products. Transmission test platforms generally use manual operation, and the monitoring of the test process and the collection and processing of test data are cumbersome and low in accuracy. It is not easy to achieve multi-parameter automatic control and failure judgment. Therefore, a parallel gear pair test bench is urgently needed. Utility Model Content
