The invention relates to the technical field of engineering machinery, in particular to a steering hydraulic system and an engineering vehicle. Compared with the prior art, oil flowing out of the priority valve in the steering process is only used for steering, and oil flowing out of the steering gear and the priority valve passes through the main valve, so that it is guaranteed that the oil only participates in steering in the steering process, and then it is guaranteed that the steering speed is high; and the second throttling element is arranged between the third oil inlet and the fourth oil outlet, so that oil entering the hydraulic control reversing valve can be throttled, the reversing temperature of the hydraulic control reversing valve is further realized, and stable steering is further realized.

    本发明涉及工程机械技术领域,尤其涉及一种转向液压系统及工程车辆。相较于现有技术而言,由于在转向过程中优先阀流出的油液只用于转向,且转向器与优先阀流出的油液均通过主阀,这样保证了在转向过程中油液只参与转向,进而保证了转向速度快,而第二进油口与第三进油口之间设置有第一节流件,第三进油口与第四出油口之间设置有第二节流件,则能够对进入液控换向阀的油液进行节流,进而实现液控换向阀换向温度,进而实现转向平稳。
