Abstract
The invention relates to a brake master cylinder assembly, which mainly comprises a brake oil storage cup, a master cylinder body, a first piston assembly and a second piston assembly, wherein the brake oil storage cup is fixed on the upper part of the master cylinder body; an oil outlet of the brake oil storage cup is mutually matched with an oil inlet of the master cylinder body; a sealing rubber cup is arranged at a connector; the first piston assembly and the second piston assembly are arranged in the master cylinder body, and are mutually connected in series. The brake master cylinder assembly has the beneficial effect that the working stroke is increased, meanwhile, the length of the cylinder body can be shortened as soon as possible, the spatial arrangement of a vehicle is favored, after the working stroke of the brake master cylinder is lengthened, the volume of liquid provided when the vehicle is braked can be increased, the braking force is increased, and the safety of the vehicle is enhanced.
Description
Technical field
The present invention relates to the structure in brake system of car, especially a kind of brake master cylinder assembly.
Background technology
Brake master cylinder assembly is the parts that the braking liquid potential source is provided in motor vehicle braking system.(brake master cylinder assembly design drawing) its effect is that the power that chaufeur is acted on pedal converts hydraulic pressure to, promotes wheel cylinder and makes drg work, thereby realize automobile brake.During brake off, pull back spring makes the pedal return.Its cylinder body Design of length of conventional brake master cylinder assembly lengthens with the increasing of forced stroke, the motion of leather package and power piston and together with motion, thereby easily wearing and tearing.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of simple in structure, compact brake master cylinder assembly is provided.
The present invention solves the technical scheme that its technical matters adopts: this brake master cylinder assembly, mainly comprise braking oil storage cup, master cylinder body, first piston assembly and the second piston assembly, the braking oil storage cup is fixed in master cylinder body top, the oil outlet of braking oil storage cup and the oil inlet of master cylinder body cooperatively interact, and be provided with leather package at interface, be provided with first piston assembly and the second piston assembly in master cylinder body, first piston assembly and the second piston assembly are connected in series mutually.
Described first piston assembly overcoat has the leather cup of paying.
Described the second piston assembly overcoat has primary cup.
Between described braking oil storage cup and master cylinder body, by bolt of rear end plate, fix.
Described braking oil storage cup is provided with the clutch interface.
The effect that the present invention is useful is: the present invention is in the increasing of its forced stroke, and cylinder body length shortens as far as possible, is beneficial to motor space and arranges, after the master brake cylinder forced stroke lengthens, during automobile brake, provide liquid volume to increase, braking force increases, and has strengthened the safety of automobile.
The accompanying drawing explanation
Fig. 1 is master's TV structure schematic diagram of the present invention;
Fig. 2 is side-looking structural representation of the present invention.
Description of reference numerals: first piston assembly 1, pay leather cup 2, leather package 3,4, the second piston assemblies 5 of braking oil storage cup, primary cup 6, master cylinder body 7, bolt of rear end plate 8, clutch interface 9.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in the figure, this brake master cylinder assembly, mainly comprise braking oil storage cup 4, master cylinder body 7, first piston assembly 1 and the second piston assembly 5, braking oil storage cup 4 is fixed in master cylinder body 7 tops by bolt of rear end plate 8, the oil outlet of braking oil storage cup 4 and the oil inlet of master cylinder body 7 cooperatively interact, and be provided with leather package 3 at interface, leather package 3 is fixed on master cylinder body 7, not with the motion campaign of piston, be not easy wearing and tearing, extended service life, be provided with first piston assembly 1 and the second piston assembly 5 in master cylinder body 7, first piston assembly 1 and the second piston assembly 5 are connected in series mutually.First piston assembly 1 overcoat has leather cup 1, the second piston assembly 5 overcoats of paying that primary cup 6 is arranged.Braking oil storage cup 4 is provided with clutch interface 9.
In the situation that the bulk shape size constancy, by changing the size of piston, thereby it is long to have increased forced stroke, has indirectly realized the shortening of master cylinder body 7 length.Master brake cylinder forced stroke long enough, motor space arranges that axial distance is enough short.
When stepping brake pedal, promote first piston assembly 1 by bindiny mechanism, master brake cylinder is started working.Further depress brake pedal, build-up pressure in master brake cylinder and pipeline, act on the power produced in first piston assembly 1 and the second piston assembly 5, and the braking liquid in second piston assembly 5 its loops is set up identical brake-pressure equally in two loops.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
