The linkage type brake main pump comprises a pump body, a main piston, an auxiliary piston, an oil inlet, a main spring, an auxiliary spring, a first oil outlet, a second oil outlet, a sealing ring, a push rod, a piston cavity, a front brake hand pump, a front brake pump and a rear brake pump. The first oil outlet of the linkage type brake main pump is connected with the rear brake pump, and the second oil outlet of the linkage type brake main pump is connected with the front brake pump, so that the front brake pump and the rear brake pump of the vehicle can be braked simultaneously by the front brake hand pump and the linkage type brake main pump on the vehicle. Through mutual superposition of the front brake hand pump and the linkage type brake main pump, the situation that the brake force of the vehicle is insufficient due to abrasion of brake pads of the front brake pump and the rear brake pump of the vehicle is avoided. The linkage type brake main pump is simple in structure and convenient and fast to install, and the front brake main pump and the rear brake main pump of the vehicle can achieve simultaneous braking of the front wheels and the rear wheels without changing the structure of an existing vehicle.
联动式刹车主泵包括有泵体、主活塞、副活塞、进油口、主弹簧、副弹簧、第一出油口、第二出油口、密封圈、推杆、活塞腔、前刹手泵、前刹泵、后刹泵。联动式刹车主泵的第一出油口连接后刹泵,第二出油口则连接前刹泵,使车辆上的前刹手泵与联动式刹车主泵,都可以对车辆的前刹泵与后刹泵同时实施制动。通过前刹手泵和联动式刹车主泵的相互叠加,使车辆的前刹泵以及后刹泵不会因刹车片的磨损,而造成车辆制动力的不足。联动式刹车主泵的结构简单,安装便捷,使其不需要更改现有车辆的结构,就可以使车辆的前刹主泵和后刹主泵都能够实现前后轮的同时刹车。
