A hydro-pneumatic suspension hydraulic system comprises an energy supply unit, two vehicle posture adjusting units and an energy accumulator unit, and the two vehicle posture adjusting units are used for adjusting the poses of a front axle and a rear axle. Comprising a reversing valve I, a reversing valve II, a bidirectional hydraulic motor I, a bidirectional hydraulic motor II, a throttling valve I, a throttling valve II, a double-hydraulic-control one-way valve I, a double-hydraulic-control one-way valve II, a left front/rear axle suspension oil cylinder and a right front/rear axle suspension oil cylinder. Oil with the same amount is input into a left front/rear axle suspension oil cylinder and a right front/rear axle suspension oil cylinder, and a throttling valve I and a throttling valve II which are respectively connected with a bidirectional hydraulic motor I and a bidirectional hydraulic motor II in parallel are used for correcting synchronous errors so as to realize synchronous lifting of the suspension oil cylinders; by optimizing each component unit in the hydro-pneumatic suspension hydraulic system, the pose of the vehicle under each working condition can be flexibly adjusted, and the driving stability of the vehicle is improved.

    一种油气悬架液压系统,包括能量供给单元、车姿调节单元以及蓄能器单元,所述车姿调节单元设有两组,用于调整前桥和后桥的位姿,包括换向阀Ⅰ、换向阀Ⅱ、双向液压马达Ⅰ、双向液压马达Ⅱ、节流阀Ⅰ、节流阀Ⅱ、双液控单向阀Ⅰ、双液控单向阀Ⅱ、左前/后桥悬架油缸、右前/后桥悬架油缸,通过刚性连接的双向液压马达Ⅰ和双向液压马达Ⅱ在回路中作为流量分配装置,把等量的油液输入左前/后桥悬架油缸和右前/后桥悬架油缸,与双向液压马达Ⅰ和双向液压马达Ⅱ分别并联的节流阀Ⅰ和节流阀Ⅱ用于修正同步误差以实现悬架油缸同步升降;本发明通过优化油气悬架液压系统中的各个组成单元,可实现灵活调整车辆在各个工况下的位姿,提高车辆行驶稳定性。
