Abstract:By analyzing the structure and operating principles of ZF4WG308 power shift gearbox and its’ theoretical hydraulic changes in the shifting process the AMESim model was set up. Through simulation the results of simulation is carried on, then are studied by comparing with the theoretical curve of oil pressure .Based on the simulation model and take pressure setting valves as research objects, influence of different parameters of pressure setting valves’s spring on the cushioning properties is studied. The research findings not only can be used to provide guidance for pressure regulating valves’ selection and improved design, but also can be used to provide theoretical help for the study of the related hydraulic field.
Key words:pressure regulating valve;AMESim;spring of pressure setting valve;buffer characteristics
