The invention relates to the technical field of braking, in particular to a braking main pump and a linkage braking system. The brake main pump comprises a pump body, a first piston, a second piston and a piston push rod; the pump body is provided with a piston cavity, a first oil guide hole and a second oil guide hole; the first oil guide hole is communicated with the second cavity, the second oil guide hole is communicated with the third cavity, the first oil guide hole is used for being communicated with a foot brake pump body, and the second oil guide hole is used for being connected with a front brake or a rear brake; the piston push rod is connected with the pump body and is in transmission connection with the first piston, and the piston push rod is used for driving the first piston to move under the driving action of external force; the second piston is used for moving towards the direction of the second oil guide hole under the driving effect of the first piston or the pressure effect of the second cavity, so that the front brake or the rear brake conducts braking. According to the brake main pump, the structure of a linkage brake system can be simplified, and the use cost of the linkage brake system is reduced.
本发明涉及制动技术领域,具体而言,涉及一种制动主泵及联动制动系统。制动主泵包括泵体、第一活塞、第二活塞及活塞推杆;泵体设置有活塞腔、第一导油孔及第二导油孔;第一导油孔与第二腔室连通,第二导油孔与第三腔室连通,第一导油孔用于与脚刹泵体连通,第二导油孔用于与前制动器或后制动器连接;活塞推杆与泵体连接,并与第一活塞传动连接,活塞推杆用于在外力的驱动作用下驱动第一活塞运动;其中,第二活塞用于在第一活塞的驱动作用下或第二腔室的压力作用下朝向第二导油孔的方向运动,以使得前制动器或后制动器制动。该制动主泵能够简化联动制动系统的结构,并降低联动制动系统的使用成本。
