| Abstract: | A simulation model with pressure, flux and power of a hydraulic system of steel pushing V--belt continuously variable transmission was established. The pressure, flux and power of the hydraulic system were simulated under cycle driving conditions. Based on analysis on the results of simulation, the energy saving measures were proposed. The design ,dynamic modeling and simulation and analysis of the CVT hydraulic system with double-pump were processed. From the simulation results, it is clear that the power matching system using double-pump can improve efficiency of the CVT hydraulic system greatly. So the theoretical foundation on energy saving control of the CVT hydraulic system is built by the research work. |
