The invention provides a hydraulic suspension control system and an engineering vehicle, and relates to the technical field of hydraulics, the hydraulic suspension control system comprises a multi-way valve, a suspension switching valve, a front suspension oil cylinder group, a rear suspension oil cylinder group and a middle suspension oil cylinder, one oil outlet of the multi-way valve is connected with one oil inlet of the front suspension oil cylinder set and one oil inlet of the suspension switching valve, the other oil outlet of the multi-way valve is connected with the other oil inlet of the rear suspension oil cylinder set and the other oil inlet of the suspension switching valve, an oil outlet of the suspension switching valve is connected with the middle suspension oil cylinder, and the suspension switching valve is used for switching oil ways. And the middle suspension oil cylinder is communicated with the front suspension oil cylinder group or the rear suspension oil cylinder group. By changing the communication mode of the suspension oil cylinder, the pressure received by the front wheels and the rear wheels of the vehicle is adjusted when the vehicle is in a full-load uphill and downhill state, so that the engineering vehicle runs more stably when the engineering vehicle is in a full-load uphill and downhill state, and the running safety of the engineering vehicle is improved.

    本发明提供了一种液压悬挂控制系统及工程车辆,涉及液压技术领域,液压悬挂控制系统包括多路阀、悬挂切换阀、前悬挂油缸组、后悬挂油缸组及中间悬挂油缸,多路阀的进油口用于与油箱连接,多路阀的一个出油口与前悬挂油缸组及悬挂切换阀的其中一个进油口连接,多路阀的另一个出油口与后悬挂油缸组及悬挂切换阀的另一个进油口连接,悬挂切换阀的出油口与中间悬挂油缸连接,悬挂切换阀用于切换油路,以使中间悬挂油缸与前悬挂油缸组或后悬挂油缸组连通。本发明通过改变悬挂油缸的联通方式,使车辆在满载上下坡状态时,调整车辆前轮与后轮收到的压力,使工程车辆在满载上下坡时行驶更平稳,提升了工程车辆行驶安全性。
