Abstract
The invention belongs to the Automobile air brake equipment, is a kind of full-automatic safety compensation structure for vehicle praking, is used to guarantee running safety.Mainly control elastic braking chamber and be totally independent of former motor vehicle braking system by two-way valve, use with the vehicle braked system support of all kinds of employing compressed air brakes, thereby realize moment when the unexpected et out of order of brake system of driving vehicle, this structure just drops into immediately automatically, still can keep braking function under the situation of the air braking system et out of order of assurance driving vehicle, thereby avoid and reduce the generation of serious accident.The present invention is simple in structure, and is safe and reliable, highly efficient durable, remarkable benefit.
Description
The invention belongs to brake device for car, is a kind of full-automatic safety compensation structure for vehicle praking, is used to guarantee the traffic safety of automobile.
The vehicle of available technology adopting compressed air brake is more, and for example east wind 140, liberates 141 grades and all adopts traditional air braking system.Glancing impact, the air-flow of band certain pressure be through master brake cylinder, pipeline and enter brake repair room, thus because gaseous tension promotes the brake repair room epithelium makes its push rod promote brake shoe expander action to realize braking function.Desire is removed the then exhaust of its braking function, makes the epithelium reinstatement attitude under pull back spring is auxiliary in the brake repair room, the vehicle brake off.Yet in the vehicle ' process, often make the car brakeing disabler because of faults such as pipeline gas leakage in master brake cylinder et out of order, front and back brake repair room epithelium breakage, the brake system, make the vehicle in travelling lose braking and cause the traffic safety accident, cause the loss of lives and properties.
The problem of not having safety control at driving vehicle behind the air braking system et out of order in the prior art, the objective of the invention is to: a kind of full-automatic safety compensation structure for vehicle praking is provided, control elastic braking chamber and be totally independent of former motor vehicle braking system by two-way valve, with the supporting use of the brake system of all kinds of employing air brake vehicle, thereby realize moment when the unexpected et out of order of brake system of driving vehicle, this structure just drops into immediately automatically, still keep braking function under the situation of the air braking system et out of order of assurance driving vehicle, thereby avoid and reduce the generation of serious accident.Simultaneously, the present invention can also be in former brake system fault under the eliminating state, guarantees that vehicle safety is emergent to travel.Also can realize parking function by manual control two-way valve.Intact just often in the former brake system of vehicle, this structure will not drop into, once during the vehicle brake et out of order, this structure moment drops into, to guarantee the realization of emergency brake of vehicle.
The present invention is mainly by two-way valve (6), elastic force chamber (9), hand lever (12), backguy (13) pull bar (8), pressure valve (16), electromagnetism check valve (17), switch (18), electromagnetic valve (19) and indicator lamp (14), buzzer phones (15) etc. are partly formed.By the switching of two-way valve pull bar (8) the instruction two-way valve (6) that is connected with former car brakeing master cylinder arm (3), thereby make, realize the safety arrestment compensation of vehicle through the action of the elastic force chamber (9) of bleed pressure effect.Can use manual draw bar (12), backguy (13) when needing Parking thus the open and close of handling two-way valve is realized the braking during standstill of vehicle.When this structure drops into, then bright, buzzer phone (15) work of display lamp (14) of contact (7) conducting.
Concrete structure of the present invention is: two-way valve (6) is connected with former master brake cylinder arm (3) through pull bar (8), the admission port of two-way valve and former car air tank (2) are connected by the road, and connect through tracheae and elastic force chamber (9), the gas port that often begins to rehearse of two-way valve (6) is done the time spent and is communicated with atmosphere; Elastic force chamber (9) through interface fork (11) be connected with the push rod of former brake repair room (4), in the vehicle ', glancing impact is stepped on brake pedal (5), make master cylinder arm (3) action and realize total pump work, brake repair room (4) before and after pressurized air is led to is by the road then realized braking.Point is stopped (delaying glancing impact), the stroke of brake pedal (5) uses not enough, master cylinder arm (3) stroke does not also reach range, the mobile admission port that is not enough to open the exhausr port of two-way valve (6) and closes two-way valve of the pull bar (8) that links to each other with master cylinder arm (3) is not so structure of the present utility model is worked.When emergency braking occurring, brake pedal (5) is stepped on sufficient range, pull bar this moment (8) is enough to two-way valve (6) inlet close, when brake pedal (5) is stepped on to range, make switch (18) turn-on power, this moment as the brake system et out of order, must cause brake repair room (4) pipeline inner air pressure to be lower than safe pressure or be zero, cause the pressure valve (16) can not closed normal circuit opening contact, unidirectional electrical magnet valve (17) does not have to keep under the power supply situation the normal open state of exhausr port, pressurized air in elastic force chamber this moment (9) is discharged through exhausr port, elastic force chamber (9) work, the pulling force that is the spring of elastic force chamber (9) is pitched the push rod that (11) spur former brake repair room (4) through interface, drives braking regulating arm (26) thereby the realization car brakeing.This moment, pressure valve (16) interior normally closed contact was not opened, conducting electromagnetic valve (19), block air tank (2) compressed air and flow to master brake cylinder (3).
During emergency braking, when brake system is working properly, pressure valve (16) is subjected to normal pressure in brake repair room (4) pipeline, the closed turn-on power of normal circuit opening contact in the pressure valve (16), make check valve (17) power connection, close exhausr port, elastic force chamber (9) compressed air can not be discharged, and does not therefore work.Because the interior normally closed contact of pressure valve (16) makes it to disconnect under brake repair room (4) pipeline normal pressure this moment, electromagnetic valve (19) does not have power supply, does not block in the air tank (4) and continues to master brake cylinder (3) air feed.Keep brake repair room (4) normal operation.In braking procedure, when two-way valve (6) when entering mode of operation, contact switch (7) conducting, buzzer phone (15) and display lamp (14) work.After brake pedal (5) resets, the air inlet open of two-way valve (6), elastic force chamber (9) reset, and vehicle is a brake off.During Parking, can make two-way valve (6) work through backguy (13), close admission port, and make elastic force chamber (9) work, make vehicle reach braking, guarantee the requirement of braking during standstill by pull bar (12).
The present invention is zero or during less than safety air pressure at braking gas source pressure, but full automaticity make vehicle be in braking mode, just automatically terminate braking mode when being equal to or greater than safe pressure when vapour source pressure rises to.Thereby forcibly stop driving against traffic regulations of vehicle.
Compare with prior art, the present invention is simple in structure easy for installation, and easily debugging is convenient to safeguard.It is totally independent of former car brake system, just just puts into operation automatically when emergency braking and former car brake failure.So this structure safe in utilization, reliable, highly efficient durable, economic benefit and obvious social benefit.
