Calculations and Parameter Optimization of the Hydrostatic Drive Framework Car Power System

Analysis of the working principle of the system frame vehicle hydrostatic drive,and the system pressure,speed and capacity of the hydraulic drive system efficiency.Through the framework of three types of static parameter calculation and matching research,puts forward the frame of vehicle hydraulic driving method selection system components and parameters optimization of the matching principle.Conclusion:not only to achieve the reasonable matching static work point of the hydraulic drive system,but also need to adjust the pump and motor output process,so that the hydraulic device is always working in high efficient area,the engine work under quasi-static conditions,so as to ensure the engine and hydraulic system has more stable conditions and use the power and economy of good the.
