Abstract
The utility model relates to an inflatable vehicle emergency braking auxiliary device comprises an air storage tank 1, a reversing valve 5, two to eight telescopic air bags 7 connected with the reversing valve, wherein, the telescopic air bags 7 are installed on the front axle or the rear axle of a vehicle. A power supply on-off switch 14 and a keyswitch 13 are installed on a vehicle instrument table. When a vehicle is driven, the power supply on-off switch 14 is switched on beforehand. During emergency braking, the keyswitch 13 is closed or a braking device is treaded by a foot. The telescopic air bags 7 are inflated by air in the air storage tank 1. The telescopic air bags 7 are quickly expanded and contacted with the ground to enlarge contact area. Large friction force is generated to reach the goal of auxiliary braking. The utility model has the advantages of convenient operation and small size.
Description
The utility model relates to the auxiliary device of automobile brake, relates in particular to inflatable automobile emergency braking auxiliary device.
At present, the mode of automobile brake all adopts tire and ground friction to realize in the world.Along with the development of highway construction, the speed that automobile travels on highway is also more and more faster.Because the braking effect of the little generation of tire-contact area is very unsatisfactory, automobile usually leads to traffic accident because inertia continues to slide forward when meeting the obstacle emergency braking under steam.Prior art Chinese patent application number: 91233227, the authorization notification number: 2118019, denomination of invention: automobile emergency brake auxiliary device, during emergency brake, iron plate case negative is opened, and tri-prismoid falls and blocks automobile back wheel, and car assisted brake is stopped automobile.Its shortcoming is: braking effect is bad, and tire is had damage.
The purpose of this utility model is to provide a kind of and plays the auxiliary braking effect at the automobile emergency glancing impact, the inflatable automobile emergency braking auxiliary device of good braking effect.
Inflatable automobile emergency braking auxiliary device, its technical characterictic comprises:
Pneumatic part is: a porthole a of the air extractor duct of storage tank 1 connection reducing valve 2 in sequential series, pipeline 3, change-over valve 5, the admission port of the porthole b of change-over valve connection check valve 6 in sequential series and extension airbag 7, the air extractor duct of extension airbag 7 connects second porthole d of change-over valve 5, and second porthole c connects freeing pipe 10; The air bag returning device is arranged in the extension airbag 7.
Control part is: the anodal connection fuse 16 in sequential series of automobile power source, on/off switch 14, the contact of pressure power-on switch 12 and the magnet coil 9 of change-over valve 5, the negative pole of automobile power source connects the other end of magnet coil 9, and button switch 13 is parallel to the contact two ends of pressure power-on switch 12.
Principle of work: use when installing, extension airbag 7 is fixed on automobile front axle or the back axle, and button switch 13, on/off switch 14 are fixed on the instrument desk of automobile.
When the driver drives, elder generation's energized on and off switch 14, indicator lamp 15 is bright, when emergency situation takes place in the enforcement, the switch 13 that pushes button, or pin is stepped on the drg on the automobile, when the brake pipe line pressure raises, the contact of pressure power-on switch 12 is connected, and energized all can make magnet coil 9 energisings immediately, and position shown in the mobile change-over valve 5 to figure, gas in the storage tank 1 is immediately through reducing valve 2, pipeline 3, the mouth a of change-over valve 5, mouth b enters extension airbag 7 through check valve 6, at this moment, the mouth d of change-over valve 5, mouth c closes, gas enters extension airbag 7, extension airbag 7 is expanded rapidly and contact with ground, and producing rubs reaches the purpose of auxiliary braking.Otherwise, power cut-off on and off switch 14, indicator lamp 15 goes out, (or disconnect button switch 13, and when decontroling drg on the automobile with pin, the brake pipe line pressure reduces, and pressure power-on switch 12 is power cut-off immediately,) magnet coil 9 outages, change-over valve 5 automatically resets, and at this moment, mouth a, mouthful b of change-over valve 5 close, mouth d, mouthful c connect, and gas is discharged gases through mouth d, mouthful c to freeing pipe 10 from extension airbag 7 outlets.In the extension airbag 7, because the pulling force of retracing spring 17, extension airbag 7 upwards shrinks.
Advantage of the present utility model: owing to adopt extension airbag 7 auxiliary brakings, during extension airbag 7 inflations, produce friction with ground, increase and ground-surface area of contact, auxiliary braking is effective; Since adopt electronic control and air operated control, easy to operate; Volume is little, and is in light weight; By formula: the contact to earth stopping distance multiple of area ÷ tire-contact area=shortening of extension airbag, the stopping distance of automobile can be shortened several times, prevent traffic accident.
