Abstract
A pneumatic brake emergency device for automobiles is characterized in that a liquid gas pressure boosting device provided with corollary equipments including a three-way pipe, a solenoid valve and a solenoid valve switch button is additionally arranged between an air reservoir and a wet air reservoir of a braking system pipeline of an existing pneumatic brake automobile, so that an emergency device is constituted. By adopting the pneumatic brake emergency device for automobiles, when gas pressure of a braking system pipeline of an automobile is too low, the gas pressure of a pressure system can be increased quickly and promptly, so that the brake gas pressure of the automobile is ensured sufficiency, and accidents caused by brake failure can be avoided, further the lives and the safety of property of people can be guaranteed.
Description
Technical field
The utility model belongs to automobile pressure emergency brake device.
Background technology
Use the automobile of compression air brake, automobile can take place because of braking failure cause accident when low when the gaseous tension of brake line is crossed.This type of traditional automobile does not all have the low excessively emergency facility of braking pressure at present, causes the automotive safety accident to happen occasionally.
The utility model content
The technical matters that the utility model will solve provides a kind of gaseous tension when the brake system of car pipeline and crosses the automobile pressure emergency brake device that can improve air pressure, the generation of prevention automobile brake accident when hanging down.
The utility model solves the problems of the technologies described above with following technical scheme: between the wet air receiver and air receiver of the brake line that has air break automobile now; Set up the liquid gas pressure charging device of band corollary equipment three-way pipe, electromagnetic valve and an electromagnetic valve switch, form an emergency facility.
The automobile pressure emergency brake device of the utility model has been installed; When the gaseous tension of air break automobile brake line is crossed when low; But at high speed in time increases the gaseous tension of pipeline system; The braking pressure pressure that has guaranteed automobile is enough, avoids braking failure and causes the generation of accident, guarantees the people's safety of life and property.
Description of drawings
Fig. 1 is the structural representation of the automobile pressure emergency brake device of the utility model.
The specific embodiment
Between the wet air receiver 3 and air receiver 10 of the brake line that has air break automobile now, set up the liquid gas pressure charging device 4 of band corollary equipment three-way pipe 7, pressure regulating valve 6, electromagnetic valve 8 and an electromagnetic valve switch 5, form an emergency facility.
Wet air receiver 3, air receiver 10 inlet ends all have check valve 1.The liquid gas pressure charging device 4 of emergency facility is connected with wet air receiver 3, air receiver 10, the brake control valve 12 of brake system through pressure regulating valve 6, electromagnetic valve 8, three-way pipe 7, three-way pipe 9 and supply air line.Before the automobile brake, air compressor 13 is being deposited being stored in wet air receiver 3 and the air receiver 10 with certain pressure through supply air line after the air compression.When air pressure abundance and pressure reach specified value; Automobile is if will brake; Brake control valve 12 is opened; Pressurized air is passed through brake piping with certain pressure and is advanced to first compressed air brake cylinder 2 of braking front-wheel and second compressed air brake cylinder 11 of braking rear-wheel, makes compressed air brake cylinder 2 and compressed air brake cylinder 11 ability normal operation, and automobile can obtain braking.But when air compressor 13 breaks down or the pressurized air of brake control valve 12 discharging when flowing to the air supply of supply air line greater than air compressor 13, the air pressure of brake system descends immediately; When the air pressure of brake system was lower than specified value, braking pressure can not promote compressed air brake cylinder 2 and compressed air brake cylinder 11 work, will cause braking failure.Should anxious device be to cross low and automobile needs glancing impact when brake system pressure; The driver can in time open electromagnetic valve switch button 5 opens electromagnetic valve 8; Liquid gas pressure charging device 4 in the emergency facility replenishes air pressure through three-way pipe 7 to brake line; Braking pressure is increased immediately reach normal value, automobile is braked.
Claims (1)
1. automobile pressure emergency brake device; It is characterized in that between the wet air receiver and storage tank of the brake line of air break automobile; Set up the liquid gas pressure charging device of band corollary equipment three-way pipe, electromagnetic valve and an electromagnetic valve switch, form an emergency facility.
