Problems solved by technology

Due to the manufacturing and welding errors of the inertia proportional valve fixing bracket and improper operation during installation, the inclination angle after assembly cannot meet the design requirements of 10°~13°, which easily leads to unreasonable hydraulic distribution of the rear axle.

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] Such as figure 1 As shown, the embodiment of the present invention provides a brake master cylinder with an inertia proportional valve, including a brake master cylinder 2 and an inertia proportional valve 1, and the inertia proportional valve 1 includes a first subassembly 11 and a second subassembly into 12.

[0024] Wherein, the second subassembly 12 is integrally formed with the brake master cylinder 1 , and the first subassembly 11 and the second subassembly 12 are connected and fixed by bolts 14 . In the present invention, the included angle between the centerline of the combined inertial proportional valve 1 and the ground horizontal line is 10°-13°, thereby meeting the design requirements of the inertial proportional valve.

[0025] In the brake...

Abstract

The invention provides a brake master pump with an inertia proportional valve. The brake master pump with the inertia proportional valve comprises a brake master pump body and an inertia proportional valve. The inertia proportional valve comprises a first sub assembly and a second sub assembly. The second sub assembly and the brake master pump are integrally formed and connected and fixed through bolts. The included angle between the center line of the inertia proportional valve and the ground horizontal line ranges from 10 degrees and 13 degrees. By means of the scheme, the inertia proportional valve and the brake master pump body are integrally formed. Affection on performances of a brake system as a hydraulic adjustment device and a fixation support are manufactured and welded with errors or not operated in the right way is avoided. In the time of brake, the brake system can give play to the best performance, the brake distance can be shortened and safety is improved. Meanwhile, modularization is achieved with the structure, the number of parts is reduced, the management cost is reduced, man hours and cost in assembly are reduced and labor cost is saved.

Description

technical field [0001] The invention relates to an automobile accessory structure, in particular to a brake master cylinder with an inertia proportional valve. Background technique [0002] At present, auto parts are increasingly modularized, and its advantages lie in the small number of parts and high manufacturing and assembly precision, thus more effectively ensuring the performance of the car. [0003] The brake system has a large number of components, and the manufacturing and assembly are complicated. Due to low manufacturing precision or improper operation during assembly, the rationality of the theoretical hydraulic distribution of the brake system is reduced, and the maximum efficiency of the brake system cannot be exerted during the braking process of the whole vehicle. [0004] In traditional designs, the brake master cylinder is located at the front of the vehicle and the inertia proportional valve is located at the rear of the vehicle. The main function of the ...
