Charging characteristics of a hydraulic braking system with accumulator for construction vehicles

A mathematical model of charging characteristics in a full power hydraulic brake system was established based on the structure and performance analysis of a new-type accumulator charging valve. The simulation analysis of dynamic characteristics and power expending of the charging valve were conducted, and the affecting laws of the valve's system parameters and structure parameters on the charging characteristics of the system were learned. Experiments are carried out to verify the simulating model.
