The invention discloses a bidirectional rotating oil pump of a motor vehicle. A reversing plate is provided with two oil channels and two reversing plate oil holes; an oil pump cover is provided withan oil inlet hole and an oil outlet hole; an oil distribution disc is provided with two oil grooves; a reversing plate O-shaped ring is in sliding friction fit with a pump shaft; the pump shaft drivesa volume changing assembly to rotate, and the volume changing assembly generates volume change in a cavity of an oil pump body; during initial rotation and each time of initial reversing rotation ofa driving shaft, friction force between the driving shaft and the reversing plate O-shaped ring is greater than shear force, and the reversing plate can rotate with the driving shaft; a reversing plate limiting pin controls and limits the rotating angle of the reversing plate; the reversing plate is limited by the limiting pin, and the pump shaft rotates in the reversing plate O-shaped ring; whenthe oil pump rotates clockwise and rotates anticlockwise, the reversing plate automatically switches an oil suction cavity and an oil delivery cavity to be connected with the oil inlet hole and the oil outlet oil; and oil is supplied to a system under the situation of changing the rotating direction. According to the bidirectional rotating oil pump of the motor vehicle, after the driving rotatingdirection of the oil pump is changed, the oil is normally supplied to the system without changing the directions of an oil inlet and an oil outlet of the oil pump.

    本发明公开一种机动车双向转动油泵;在换向板设有两个油道、两个换向板油孔;油泵盖上具有进油孔、出油孔;配油盘上具有两个油槽;换向板O形圈与泵轴滑动磨擦配合;泵轴驱动容积变化组件转动,容积变化组件在油泵体腔室内产生容积变化;驱动轴初始转动和每次初始换向转动时,驱动轴与换向板O形圈间磨擦力大于剪切力,换向板可随驱动轴转动;换向板限位销控制限定换向板转动角度;换向板经限位销限位,泵轴在换向板O形圈间转动;油泵在顺时针旋转与逆时针旋转时,换向板自动切换吸油腔、输油腔与进、出油孔的连接;满足改变旋转方向的情况下向系统供油;本发明实现了油泵在驱动旋向发生改变后,不用改变油泵的进油口、出油口方向的情况下正常为系统供油。
