Embodiment 1

[0031] Embodiment 1: see figure 1 The anti-failure braking system of the automobile brake comprises an air compressor 8, an air filter 9, an air storage cylinder 10, an air pipe 12 and a four-circuit protection valve 11, a foot brake mechanism 6 and a hand brake mechanism 7, a relay valve 8, and The spring energy storage air chamber 4, the front axle and the rear axle brake 3, and the air circuit of the braking system also include an air pressure monitoring and alarm device 13 and the like. Wherein, on the ejector rod 126 of foot brake mechanism 6, anti-failure brake main valve 1 is installed, and anti-failure brake main valve 1 is provided with air inlet 154, air outlet 155, control air inlet 156 and control air outlet 157; the air inlet 154 communicates with the gas cylinder 10 through the air pipe, and the air outlet 155 communicates with the control port of the relay valve 8 through the air pipe, and the air inlet of the relay valve 8 communicates with the gas cylinder 10...

Embodiment 2

[0052] Embodiment 2: The content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the lower end of the valve seat is directly in contact with a thimble, and only one set of braking system is used.

Embodiment 3

[0053] Embodiment 3: The content is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that only one upper piston is arranged in the upper body cavity, and there is no follower piston, so the upper piston is directly a driving component. The center of the upper piston is provided with a plug, and the peripheral edge of the upper piston is provided with a limiting flange. The upper piston divides the upper body cavity into upper and lower air chambers, and only one control air inlet is arranged on the upper body, and the control air inlet communicates with the upper air chamber.

Abstract

The invention discloses an automobile anti-ineffectiveness brake system which comprises an air compressor, an air filter, an air storage cylinder, an air delivery pipeline, a multiple-loop protective valve, a foot / hand brake mechanism, a relay valve, a spring energy-storage air chamber, a front-axle and / or back-axle brake, an anti-ineffectiveness brake main valve and an anti-ineffectiveness triple-control relay valve. By the automobile anti-ineffectiveness brake system, brake moment can be effectively compensated in time when in situations of system failure and blockage, component jamming, pressure reduction and quick leakage, and ineffectiveness of front wheels or ineffectiveness of back wheels or ineffectiveness of the complete automobile can be remedied. Further, the automobile anti-ineffectiveness brake system is convenient to mount, low in installation cost, flexible in operation, excellent in performance, and capable of effectively overcoming defects of ineffective brake, poor brake and the like in the prior art. In addition, with the automobile anti-ineffectiveness brake system, safety and reliability of the anti-ineffectiveness brake technology can be improved so that popularization and implementing of the anti-ineffectiveness brake technology are facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an anti-failure braking system for automobiles. Background technique [0002] Brake failure and failure can be divided into rear axle, front axle and the whole vehicle - because air brake technology is mainly used in medium and large vehicles, and medium and large vehicles are often prone to various reasons such as poor working conditions and defects in traditional braking technology. Cause brake failure, poor braking. For example, various factors such as: low-temperature system pipelines are blocked by water accumulation, system components are frozen and issued, high and low temperature system pipe fittings and components are damaged and leak air, etc., seriously affect the braking reliability. [0003] According to the basic safety requirements of the traditional air brake technology, the following two auxiliary brakes must be provided in addition to the main brake ...
