The utility model relates to an automobile part, particularly to an automobile steering power pump, which comprises a pump body, a rotating shaft arranged in the pump body, and an end cover arranged on the pump body, wherein the rotating shaft is connected with a rotor and a stator sequentially; a low-pressure oil inlet tank and a high-pressure oil outlet tank are arranged at the two ends of the rotor and the stator respectively; the low-pressure oil inlet tank is communicated with a low-pressure oil path; and the high-pressure oil outlet tank is communicated with a high-pressure oil outlet path arranged outside the high-pressure oil outlet tank. In the utility mode, the two tanks, namely the oil inlet tank and the oil outlet tank are made of non-metal aluminum oxide and silicon oxide through high-temperature sintering, and both the smooth finish and the wearing resistance of each of the oil inlet tank and the oil outlet tank are superior to metal products, so that the friction coefficient of the rotator to a
