摘要(Abstract)：

为了提高轮式挖掘机制动系统的可靠性,采用换向阀和控制阀的组合形式设计了一种双回路蓄能器充液阀,并在单回路的基础上增加了一个内置梭阀,能够同时为前、后桥2个蓄能器迅速充液。利用AMESim软件仿真分析了前、后桥蓄能器压力的变化和充液阀至下游流量的变化,结果表明充液过程中前、后桥蓄能器压力上升迅速且平稳,到达上限压力时换向阀迅速换向;针对仿真结果,对充液阀进行了充液试验,试验结果中前、后桥蓄能器压力变化曲线与仿真结果基本吻合。研究结果表明设计的充液阀充液过程迅速且平稳,能够在工程车辆的全液压制动系统及相关领域中得到广泛应用。
In order to improve the reliability of the braking system of the wheeled excavator,a type of dual-circuit accumulator charging valve was designed in the combined form of reversing valve and control valve,and a built-in shuttle valve was added on the basis of the single circuit,in this way,it can charge the liquid simultaneously for two accumulators in the front and rear bridges quickly.The pressure change of the accumulators in front and rear bridges and the flow rate change of the charging valve to downstream flow rate were analyzed using AMESim software. The results show that the pressure of the accumulators in front and rear bridges rises quickly and smoothly in the charging process,the reversing valve reverses quickly when the pressure rises to the upper limit of the pressure;charging test for the charging valve was carried out according to the simulation results,and the pressure change curves of the accumulators in front and rear bridges in test results are basically in agreement with the simulation results. Research results show that the charging process of the designed charging valve is quickly and smoothly,it can be applied widely in the full hydraulic brake system and other related areas of the engineering vehicles.
