The invention discloses a double-acting vane pump type power steering oil pump for a passenger car, which comprises a pump body, a pump core assembly, an oil distribution disc, a pump cover and a pump shaft, the pump core assembly comprises a rotor, a stator and vanes, the vanes are movably arranged on the rotor, and after the rotor rotates, under the double action of centrifugal force and pressure oil, the vanes are driven to rotate by a motor. The blades move to the positions where the blades make contact with the inner curved surface of the stator, the blades, the outer surface of the rotor, the inner curved surface of the stator, the oil distribution disc and the pump cover form four sealed working oil cavities, and the volumes of the working oil cavities change along with rotation of the rotor. The double-acting vane pump type power steering oil pump for the passenger car is simple in design structure, low in machining difficulty, few in parts, low in cost and capable of reducing working noise. The invention further discloses an automobile steering system.

    本发明公开了一种双作用叶片泵式乘用车用动力转向油泵,包括泵体、泵芯组件、配油盘、泵盖和泵轴,泵芯组件包括转子、定子和叶片,所述叶片为可移动的设置于所述转子上,转子转动后,在离心力和压力油的双作用下,所述叶片移动至与所述定子的内曲面相接触的位置,叶片分别与转子的外表面、定子的内曲面以及配油盘、泵盖组成4个密封的工作油腔,工作油腔的容积随着转子转动而发生变化。本发明的双作用叶片泵式乘用车用动力转向油泵,设计结构简单,加工难度低,零部件少,成本低,可以降低工作噪音。本发明还公开了一种汽车转向系统。
