The invention provides a double-operation control hydraulic steering system and an engineering vehicle, the double-operation control hydraulic steering system comprises an oil pump, a flow amplification valve group, a steering gear, an electric control steering valve, a steering wheel priority valve and a steering execution mechanism, the oil pump, the flow amplification valve group and the steering execution mechanism are sequentially in hydraulic transmission connection, the pilot control end of the flow amplification valve group is communicated with the steering gear and is communicated with the electric control steering valve through the steering wheel priority valve, and the steering gear is communicated with the control end of the steering wheel priority valve. The steering wheel control loop is responded preferentially when the steering wheel and the electric control handle are operated at the same time, the control contradiction between the steering wheel steering and the electric control handle steering is avoided, and the operation safety is improved.
本申请提供了一种双操纵控制的液压转向系统及工程车辆,其中,双操纵控制的液压转向系统包括油泵、流量放大阀组、转向器、电控转向阀、方向盘优先阀和转向执行机构,所述油泵、所述流量放大阀组和所述转向执行机构依次液压传动连接,所述流量放大阀组的先导控制端与所述转向器连通,且通过所述方向盘优先阀与所述电控转向阀连通,所述转向器与所述方向盘优先阀的控制端连通。满足方向盘转向和电控手柄转向的操纵需求,在同时操纵方向盘和电控手柄时优先响应方向盘控制回路,避免方向盘转向和电控手柄转向发生控制矛盾,提升操作安全性。
