The two-way two-stage pressure boosting brake pump comprises two brake pump units, each brake pump unit comprises a valve body, an oil outlet connector is arranged at the front end of each valve body, an oil outlet is formed in each oil outlet connector, and the front end of each oil outlet is connected with a brake piston; an oil inlet connector and a backpressure one-way valve are installed on the valve body, and a piston sleeve is arranged in the valve body. A Y oil way is formed; the front section of the brake push rod is a small-diameter section, and the rear section is a large-diameter section; a spring containing hole and an X oil way are formed in the small-diameter section, and a liquid filling one-way valve is arranged between the spring containing hole and the X oil way. A sealing face is arranged in the oil inlet connector, a check one-way valve is arranged below the sealing face, and a one-way valve reset spring is arranged on the check one-way valve in a sleeved mode. The two brake pump units are communicated through a synchronous one-way valve. The problem of insufficient pressure of a large-displacement brake pump is solved, the structure is simple, and the price is low; left and right braking forces are equal through the synchronous one-way valve, and vehicle rotation caused by braking force difference is avoided.

    本发明公开了一种双路二级压力增压制动泵,包括两个制动泵单元,所述的制动泵单元包括阀体,阀体前端设有出油接头,出油接头内设有出油口,出油口的前端与制动活塞相连接;阀体的上安装有进油口接头和背压单向阀,阀体内设有活塞套;开设有Y油路;制动推杆前段为细径段,后段为粗径段;细径段的内部开设有弹簧容纳孔和X油路,弹簧容纳孔与X油路之间设有充液单向阀;进油口接头内密封面,密封面的下方设有一个止回单向阀,所述的止回单向阀上套设有单向阀复位弹簧;两个制动泵单元之间通过同步单向阀相连通。本发明解决了大排量制动泵压力不足的问题,结构简单价格低廉;通过同步单向阀使左右制动力相等,避免因制动力差异导致车辆转动。
