Description

High-speed car burst tyre direction anti-deflection device

The utility model is a kind of high-speed car burst tyre direction anti-deflection device, belongs to the vehicle traveling direction stability techniques.

When automobile is run at high speed,, cause the particularly unexpected explosion of front-wheel of automobile one side wheel tire because of reasons such as wheel mass difference or improper uses on road, gas is hurried to leak, tire pressure descends rapidly, and resistance to motion is big, makes vehicle traveling direction rapidly to the side direction sideslip of blowing out.Because to blow out is accidental phenomenon, before chaufeur was taken measures, automobile left original travel direction with regard to get out of hand, even bumped against adjacent vehicle, spacer or turn over the phenomenon of bob from eminence, caused personal injury and property damage.It is reported in the traffic accident that on express highway, occurs at present, have 15～20% traffic accidents to blow out and cause owing to single wheel.And the anti-deflection device that has not yet to see a kind of relatively actv. high-speed car burst tyre direction prevents the automobile sideslip can make the automobile of running at high speed occur blowing out suddenly the time effectively, keeps the original travel direction of automobile, guarantees traffic safety.

The purpose of this utility model be exactly for study, design, provide a kind of can be when high-speed car occurs blowing out suddenly, can reliably, effectively prevent the automobile sideslip, keep the original travel direction of automobile, guarantee automotive safety, prevent or reduce the high-speed car burst tyre direction anti-deflection device of the generation of personal injury and property damage accident.

The utility model is realized by following structure technology scheme; The structural representation of high-speed car burst tyre direction anti-deflection device as shown in Figure 1, its control circuit schematic diagram as shown in Figure 2, its air chamber structure scheme drawing front view as shown in Figure 3, its air chamber structure scheme drawing birds-eye view is as shown in Figure 4.The anti-deflection device of front axle and rear axle is separate, high-speed car burst tyre direction anti-deflection device is by wheel 1, valve nozzle 2, air chamber 3, steel pipe 4,9,

nut connector

5,8,10, swivel joint 6, interface 7, wheel valve nozzle 11, electromagnetic valve 12, air-pressure gauge 13, two-way button switch 14, Warning light 15, front axle electromagnetic valve coil 16, rear axle electromagnetic valve coil 17 connects and composes jointly, its mutual alignment and annexation are: valve nozzle 2 is welded on the air chamber 3, air chamber 3 is by its upper body 18, lower body 19 is welded, interface 7 is welded on the air chamber 3 and passes through

nut connector

8,10 and steel pipe 9 be connected with the wheel valve nozzle of removing behind the valve inside 11, air chamber inner chamber 20 can make swivel joint 6, valve nozzle 2 and interface 7 communicate, the shape and the size of front axle air chamber lower body are identical with the front-wheel hub bearing cap shim, by bolt of bearing cap air chamber 3 is fixed on the wheel hub, the shape and the size of rear axle (single entry trailing wheel) air chamber lower body are identical with the semiaxis end, by the semiaxis bolt air chamber are fixed on the semiaxis end face.Two formula trailing wheel air chambers, except that Duoing than single entry trailing wheel air chamber the interface, remainder is all identical; Swivel joint 6 is made of bearing and the seal ring between its endosome, ectosome, interior ectosome, the endosome interface is connected with electromagnetic valve 12 by nut connector 5, steel pipe 4, its endosome maintains static, and its ectosome and air chamber upper body 18 are integrally welded and can be with wheel, air-pressure gauge 13 is installed on the facia board and by pipeline and communicates with electromagnetic valve 12, two-way button switch 14, Warning light 15 are installed on the facia board, and be electrically connected mutually by lead, forward and backward axle

electromagnetic valve coil

16,17 is loaded on respectively in the forward and backward axle electromagnetic valve 12.Its principle of work is as follows: during running car, depress two-way button switch 14, make the armature contact and the fixed contact B closure of switch, electromagnetic valve circuit is connected, valve open, coaxial left-right side wheel nausea road communicate (install pipes interconnect before, valve nozzle 11 will remove tyre valve core), tire pressure is identical.When the unexpected explosion of a coaxial side wheel tire, when tire pressure descends rapidly, the opposite side tire makes both sides tire pressure identical all the time (reducing to bar pressure at last) rapidly to its inflation, and the coaxial wheel resistance to motion is identical, rotating speed is also identical, so just can prevent the high-speed car sideslip of blowing out suddenly.Judge that single wheel slowly loses heart or when changing tire, press the button switch in the operator's compartment that armature contact separate with fixed contact B when needs, the electromagnetic valve circuit cut-out, it is obstructed that the coaxial left-right sidecar is taken turns gas circuit, and anti-deflection device is inoperative.At this moment, armature contact and fixed contact A closure, Warning light is glittering, reminds chaufeur to be sure not to forget before driving and opens electromagnetic valve.Because air-pressure gauge, Warning light all are installed on the facia board, when by valve nozzle 2, observe air-pressure gauge during to inflation of tire and understand the tire pressure size, tire pressure is controlled within the requirement of regulation.Barometric when driving pressure slowly descends, and illustrates that wheel has gas leakage.If it is too high that air-pressure gauge pressure increases, the expression wheel temperature is overheated, reminds chaufeur to take corresponding measure, prevents that wheel from damaging because of unusual the use.

The utility model has following advantage and beneficial effect: (1) the utility model can be when high-speed car occurs blowing out suddenly, can prevent the automobile sideslip reliably, effectively, keep the original travel direction of automobile, still guarantee running safety, prevent or reduce personal casualty and property damage accident; (2) simple in structure, the reliable operation of this anti-deflection device, effect are remarkable, are fit to install with partially anti-on the automobile of all vehicles; (3) this device is manipulated easily, and cost is low.
