The multi-mode hydraulic steering system comprises a steering main pump, the steering main pump is connected with a steering gear and an electric control steering valve which are arranged in parallel, the steering main pump communicates with the oil inlet ends of the steering gear and the electric control steering valve, and the oil outlet ends of the steering gear and the electric control steering valve are connected with a steering execution part after being connected in parallel. The steering execution part comprises a front axle steering oil cylinder set and a rear axle steering oil cylinder set, a steering mode switching valve is connected between the front axle steering oil cylinder set and the rear axle steering oil cylinder set, and the oil inlet end of the steering gear and the oil inlet end of the electric control steering valve are communicated with an emergency oil supply part. By arranging the steering priority valve, the steering gear, the electric control steering valve and the steering mode switching valve, diversification of steering control modes is achieved, steering can be conducted by rotating the steering gear, and steering can also be controlled through the electric control steering valve.

    本发明公开了一种多模式液压转向系统,包括转向主泵,所述转向主泵连接有并联布置的转向器、电控转向阀,所述转向主泵与所述转向器、电控转向阀的进油端连通,所述转向器、电控转向阀出油端并联后连接有转向执行部,所述转向执行部包括前桥转向油缸组、后桥转向油缸组,所述前桥转向油缸组与所述后桥转向油缸组之间连接有转向模式切换阀,所述转向器、电控转向阀的进油端连通有应急供油部,本申请通过设置转向优先阀、转向器、电控转向阀、转向模式切换阀实现了转向控制方式的多样化:既可以转动转向器进行转向,也可以通过电控转向阀控制转向。
