The split type anti-impact full-hydraulic steering gear comprises a steering gear body, an L cavity and an R cavity are formed in the steering gear body, an L cavity overload valve set and an R cavity overload valve set are arranged in cavities of the L cavity and the R cavity respectively, and each overload valve set of the L cavity overload valve set and the R cavity overload valve set comprises a pressure adjusting screw, a spring, a spring seat, a valve seat and a plug. The plugs are respectively fixed on cavity bodies of the L cavity and the R cavity, one end of the spring is nested at a screw head of the pressure adjusting screw and is locked and fixed with the pressure adjusting screw through a screw, the other end of the spring is locked and fixed with the spring seat through a screw, and a steel ball is arranged between the spring seat and the valve seat. According to the hydraulic steering gear, the overload valve groups are arranged in the L cavity and the R cavity, the pressure can be buffered through the overload valve groups, the oil cylinder and the steering gear are effectively protected, and the situation that the oil cylinder and the steering gear are damaged due to the fact that external force is too large is avoided.

    本发明公开了一种分体式防冲击全液压转向器,包括转向器本体,所述转向器本体内部设有L腔和R腔,所述L腔和R腔的腔体内分别设有L腔过载阀组和R腔过载阀组,所述L腔过载阀组和R腔过载阀组的过载阀组包括调压螺钉、弹簧、弹簧座、阀座和螺堵,所述螺堵分别固定于L腔和R腔的腔体上,所述弹簧一端嵌套于调压螺钉的螺头处且通过螺丝与调压螺钉锁紧固定,所述弹簧的另一端通过螺丝与弹簧座锁紧固定,所述弹簧座与阀座之间设有钢珠。本液压转向器的L腔和R腔内设置有过载阀组,通过过载阀组可对压力提供缓冲的作用,有效的对油缸以及转向器提供了保护,避免了因外力过大,造成油缸以及转向器出现损伤的情况。
