Abstract：Transmission synchronization performance directly affects the vehicle handling, and its quantitative testing is very important. According to the demand of transmission synchronizer and assembly shift performance test, the overall design of the test bench is described, including the mechanical part, the measurement and control system and the software system. Secondly, the design of the gearbox is selected by selecting a certain gearbox. The relationship between the displacement, displacement and time of the gearbox is obtained, and the test results of the test bench are evaluated. The results show that the test system can meet the test performance requirements and provide the experimental basis for the development of transmission technology.
Key words：transmission；synchronizer；shift performance
