The invention discloses a hydro-pneumatic suspension control system, a hydro-pneumatic suspension control valve set and an engineering vehicle in the field of vehicle engineering, the hydro-pneumatic suspension control system is used for controlling a hydro-pneumatic suspension, the hydro-pneumatic suspension comprises suspension oil cylinder sets symmetrically arranged on the two sides of an axle, the suspension oil cylinder sets are provided with corresponding energy accumulators, and the energy accumulators are connected with the hydro-pneumatic suspension control valve set. The hydro-pneumatic suspension control system is characterized in that the hydro-pneumatic suspension control system comprises a first control valve set and a second control valve set, the first control valve set is connected with an energy accumulator and a rodless cavity of a suspension oil cylinder, and a rod cavity of the suspension oil cylinder is connected with the second control valve set; according to the invention, the axle can be actively lifted in a non-bearing state instead of pressing the suspension oil cylinder to retract by virtue of the dead weight of the vehicle, and the tires are lifted upwards to be away from the ground, so that the requirements of chassis maintenance and loading operation are met.

    本发明公开了车辆工程领域的一种油气悬架控制系统、油气悬架控制阀组及工程车辆,一种油气悬架控制系统,用于对油气悬架进行控制,所述油气悬架包括在车桥两侧对称布置的悬架油缸组,所述悬架油缸组配置有相应的蓄能器,其特征在于,所述油气悬架控制系统包括第一控制阀组和第二控制阀组,所述第一控制阀组与蓄能器、悬架油缸的无杆腔相连,所述悬架油缸的有杆腔与第二控制阀组连接;本发明中可以实现非承重状态下主动提升车桥,而不是依靠车辆自重下压悬挂油缸回缩,通过向上提升车桥实现轮胎离地,以便于底盘维修、上车作业的需求。
