Abstract
The utility model discloses an automobile oil pump which comprises a pump body. A pump body inner cavity is formed in the pump body. A pump shaft is arranged in the pump body inner cavity. An oil inlet channel and an oil outlet channel are arranged on the pump body, wherein the oil inlet channel and the oil outlet channel are communicated with the pump body inner cavity. An inner rotary disc is sleeved outside the pump shaft. An outer rotary disc is sleeved outside the inner rotary disc. The outer rotary disc and the inner rotary disc are arranged in the same direction of the radial direction facing outwards of the pump shaft. An oil passing hole is formed in the inner rotary disc. One end, penetrating through the pump body, of the pump shaft extends out of the pump body, so that a rotary shaft extending section is formed. A transmission gear is arranged on the rotary shaft extending section. An installation fixing base is arranged outside the pump body. Two shaft holes are formed in the pump body. The two ends of the pump shaft penetrate out of the pump body through the shaft holes. A non-oil bearing and a lining are arranged on each shaft hole. The non-oil bearing is sleeved outside the pump shaft. According to the automobile oil pump, the non-oil bearing and the lining are arranged on each portion where the pump shaft penetrates out of the pump body so that the rotation of the pump shaft can be more flexible. Meanwhile, the automobile oil pump is simpler in structure and capable of effectively reducing the production cost of the automobile oil pump.
