The invention discloses a double-plunger supercharging brake pump. A large plunger sleeve and a small plunger are nested in a brake pump shell; when the small plunger is driven to move, the small plunger and the large plunger sleeve move at the same time to quickly pump oil for the brake, so that the brake quickly moves in place, and quick response of braking action is realized; when the brake moves in place, the large plunger sleeve automatically stops moving, the small plunger continues to move, secondary pressurization is conducted on the brake, and therefore the braking force of the brake is improved. When the double-plunger pressurizing brake pump works, a hydraulic pump does not need to be additionally arranged for supplying oil to the double-plunger pressurizing brake pump, oil pumping work of a brake can be independently completed, and therefore the cost of a tractor or other motor vehicles is greatly reduced; in addition, the double-plunger supercharging brake pump performs secondary supercharging on the brake, so that the braking force of the brake is greatly improved, and the braking safety of tractors or other large motor vehicles is ensured.
一种双柱塞增压制动泵,其在制动泵壳体中嵌套设置有大柱塞套、小柱塞;当驱动小柱塞运动时,小柱塞、大柱塞套同时运动,为制动器快速泵油,使制动器快速运动到位,实现制动动作的快速响应;当制动器运动到位后,大柱塞套自动停止运动,小柱塞继续运动,对制动器进行二次增压,从而提高了制动器的制动力;该双柱塞增压制动泵工作时无需另外设置液压泵为其供油,可独立完成为制动器的泵油工作,因此极大降低了拖拉机或其他机动车辆的成本;另外该双柱塞增压制动泵对制动器的二次增压,还极大提高了制动器的制动力,从而确保了拖拉机或其他大型机动车辆的制动安全。
