DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, the front disc and rear drum CBS linkage brake pump comprises a pump body 1, an oil cup 2 arranged on the pump body 1 and a brake handle 3 for controlling the braking of the pump body 1. The pump body 1 and the brake handle 3 are connected through a linkage rocker arm 4. The pump body 1 is provided with a CBS distributor 5 under the linkage rocker arm 4 for realizing the braking force of the front and rear wheels through a complex mechanical structure and hydraulic principle. When the rider implements the braking operation, the braking force is transmitted to the CBS distributor 5 by pulling the brake handle 3 or stepping on the brake pedal. The CBS distributor 5 calculates and determines the braking force distribution ratio required for the front and rear wheels according to a preset algorithm and current vehicle status information (such as driving speed, road conditions, etc.), and then transmits the corresponding braking force to the pump body 1 respectively, so as to realize the front and rear wheels. Collaborative braking, and the linkage rocker arm 4 is respectively provided with an extrusion portion 6 and a connection portion 7, a piston 9 cavity 8 is provided on the pump body 1, a piston 9 is slidably provided in the piston cavity 8, and the front wheel braking of the motorcycle is controlled by the piston 9. The front wheel braking mainly bears most of the braking force due to its high braking efficiency and response speed, and the extrusion portion 6 abuts against the piston 9, and a brake 10 is provided on the connection portion 7. The brake 10 is installed at the lower end of the pump body 1, and the brake 10 includes a spring 11 and a protective cover 12 for protecting the spring 11. A connecting nozzle 13 matched with the brake 10 is provided at the bottom of the pump body 1, and the rear wheel braking of the motorcycle is controlled by the brake 10, and the rear wheel braking plays a role of auxiliary braking, ensuring that the vehicle maintains stability and safety during braking.

[0017] To be more specific, the pump body 1, the linkage rocker arm 4 and the brake handle 3 are connected by a bolt 14, and a return spring 15 is provided on the bolt 14 for easy return.

[0018] In further detail, the pump body 1 is provided with a brake hole 16 for connecting the front brake line.
