The high-pressure steering gear comprises a shell, a valve element and a valve sleeve, the valve sleeve is arranged in the shell, the valve element is arranged on the inner wall of the valve sleeve, the outer wall of the valve element is sleeved with a return torsion spring with a larger steering angle, a metering cycloid rotor stator pair is arranged on one side of the shell, and the metering cycloid rotor stator pair is arranged on the other side of the shell. An oil inlet groove P, a right steering oil groove R, a left steering oil groove L and an oil tank oil return groove T which are communicated with one another are formed in the shell, and double rows of second rotor and stator oil distribution radial holes and first rotor and stator oil distribution radial holes which are independent in left-right steering are formed in the shell. Advanced technologies such as flow amplification, cylinder damping vibration attenuation and wide steering angle are built in. The hydraulic steering gear has the advantages of being higher in power density, small in pressure loss, resistant to pressure impact, stable in steering and the like.

    本发明公开了一种具有超宽转角功能的高压转向器,包括壳体、阀芯和阀套,所述壳体的内部设置有阀套,且阀套的内壁设置有阀芯,所述阀芯外壁套设有转向角度更大的回位扭力弹簧,所述壳体的一侧设置有计量摆线转定子副,所述壳体内部设置有相互连通的P进油槽、R右转向油槽、L左转向油槽和T油箱回油槽,所述壳体内部设置有双排左右转向独立的第二转定子配油径向孔和第一转定子配油径向孔,该装置具有液压转向器具有27.5MPa的公称压力,内置流量放大、缸阻尼减振,宽转向角等前沿技术。使得本发明的液压转向器具有更高的功率密度,较小的压力损失,抗压力冲击和转向平稳等优势性能。
