Abstract
The utility model discloses a vacuum supercharging device for an automobile brake system, which is safe and reliable and comprises a boosting cylinder and a boosting cylinder piston arranged in a cylinder body of the boosting cylinder. A piston push rod and a boosting cylinder spring are disposed in the middle of the boosting cylinder piston, a working cylinder piston is arranged at the end of the piston push rod, a working cylinder is disposed on the periphery of the working cylinder piston, a vacuum inlet is arranged on the cylinder body of the boosting cylinder, and a one-way valve is arranged in the vacuum inlet. The vacuum supercharging device is applicable to automobile brake systems.
Description
Technical field
The utility model relates to a kind of automobile brake system, relates in particular to a kind of vacuum pressurizer that is used on the automobile brake system.
Background technology
In order to improve the braking effect of automobile, on automobile brake system, use vacuum intensifier, the effect of vacuum intensifier is when braking automobile, converts low pressure oil to high oil pressure moment, thereby reaches the effect of firm brake.Owing in the vacuum inlet port on the conventional vacuum blwr servo cylinder cylinder body check valve is not set, inevitable air can blow back in the servo cylinder, thereby causes brake failure, production safety hidden danger.
The utility model content
The technical problems to be solved in the utility model provides a kind of safe and reliable vacuum pressurizer that is used on the automobile brake system.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises servo cylinder, is located at the servo cylinder piston in the servo cylinder cylinder body, be provided with piston push rod and servo cylinder spring in the middle of the described servo cylinder piston, described piston push rod end is provided with the operating cylinder piston, described operating cylinder piston periphery is provided with operating cylinder, described servo cylinder cylinder body is provided with the vacuum inlet port, is provided with check valve in the described vacuum inlet port.
Because the utility model is provided with check valve in the vacuum inlet port, vacuum can only be entered in the servo cylinder by check valve, prevents that effectively airborne air from blowing back into phenomenons such as causing brake failure in the servo cylinder, thereby improve safety performance.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises servo cylinder 1, is located at the servo cylinder piston 2 in servo cylinder 1 cylinder body, be provided with piston push rod 3 and servo cylinder spring 5 in the middle of the servo cylinder piston 2, piston push rod 3 ends are provided with operating cylinder piston 6, operating cylinder piston 6 peripheries are provided with operating cylinder 7, servo cylinder 1 cylinder body is provided with vacuum inlet port 8, is provided with check valve 9 in the vacuum inlet port 8.
Working process of the present utility model is: feed vacuum from check valve 9, when to low oil pressure of fuel inlet fitting 10 inputs, oil pressure can promote valve piston 11 upward movements, drive diaphragm push rod 12 upward movement together, at this moment valve 13 will be closed, valve 15 will be opened, enter from air admission mouth 16 from airborne air, enter into the bottom of servo cylinder 1 by breather pipe 17, at this moment the upper space of servo cylinder piston 2 is a vacuum, and lower space is the air in the atmosphere, because the cause of pressure difference, servo cylinder piston 2 will drive piston upward movement together, piston push rod 3 oil cylinder piston 6 that will push the work forward, brakings liquid in the operating cylinder piston 6 rapid up compression work oil cylinders 7 and produce a very high oil pressure, high oil pressure will be from 20 outputs of oil pressure delivery port, convert high torque to by oil pipe and remove to promote brake facing, thereby reach the purpose of firm brake.Because vacuum can only flow by check valve 9 single directions, thereby can prevent effectively that airborne air from blowing back into phenomenons such as causing brake failure in the servo cylinder 1.
