Background technology
The seriousness that has the traffic accident of set of number explanation Chinese automobile, in 2006 there is more than 370,000 road motor traffic accidents in Kuomintang-Communist, dead people more than 90,000, wound people more than 370,000.2007 annual data accounting automobile traffic accidents are 136894, dead 30813 people, and approximately 150,000 people are injured.Decline to some extent compared with the same period of last year, but absolute number is still very large.Particularly the recoverable amount of Chinese automobile is far below some advanced countries, but motor traffic accidents rate and casualty rate are all far away higher than these countries.
Along with the new car sales volume of China in 2006 is first super Japanese, become one of problem of whole society's first concern around the traffic safety problem of personnel, vehicle and road.And automobile is in the time being kept in motion, automotive wheels is automobile and the unique part directly contacting in road surface, is also the position that engine power is finally discharged.And this point is often ignored by the public and user vehicle.
Ride safety of automobile technology is becoming Chinese vivifying emerging market focus, and as four pin---the automotive wheels of running car, it is one of most important parts in the driving safety process of garage.Statistics show, in all motor traffic accidents, because of automotive wheels tire rapidly lose heart and the tragedy causing of blowing out reach 46%; In the motor traffic accidents of highway more up to 70%.Can not rant out, the safety in automotive wheels driving process, concerning driver and crew's final and decisive juncture, is the matter of utmost importance that human pilot and car owners must pay close attention to.
According to test, the automobile accident of blowing out in the time that 100～120 kilometers of speed per hours are travelled, driver and crew's the death rate is 60%.The automobile accident of blowing out in the time that 120～140 kilometers of speed per hours are travelled, driver and crew's the death rate is 80%.The automobile accident of blowing out in the time that 140～160 kilometers of speed per hours are travelled, driver and crew's the death rate is 90%.The automobile accident of blowing out in the time that speed per hour more than 160 kilometers is travelled, driver and crew's the death rate is 100%.Blow out drive with fatigue, drive when intoxicated, driving over the speed limit is listed as one of four large killers that affect trap for automobile traffic safety, is the pernicious motor traffic accidents of maximum that causes casualties and property loss; This problem causes showing great attention to of governments at all levels of China, takes many kinds of measures to solve
The automotive wheels that vehicle uses at present, has two types, and one has inner tube of a tyre automotive wheels, another kind of automobiles without inner tubes wheel, and what in institute's passenger vehicle, substantially all use at present is automobiles without inner tubes wheel, automobiles without inner tubes wheel is progressively promoted the use of in load-carrying vehicle national requirements.Use and the advantage such as grow interval time because automobiles without inner tubes wheel has the good and inflation of good thermal diffusivity, flexibility, sealing, ride comfort, performance, but when automobiles without inner tubes wheel tire is punctured by sharp object, because sharp object residues in automotive wheels carcass, the high pressure gas of automotive wheels is known from experience and is outwards leaked or blow out puncturing position; When sharp object pierces through automobile tire and departs from automobile tire, the gases at high pressure in automobiles without inner tubes wheel leak rapidly, if automobile is blown out or leaked rapidly two kinds of situations in the process of running at high speed, motor-vehicle accident occur dangerous large, and car crash probability is high.Blowing out is that reason is many-sided, blows out reason except above-mentioned, and unstable and automotive wheels tire internal gas pressure less than two factors of automotive wheels tire internal gas pressure, are the main seeds of trouble of blowing out in vehicle traveling process in fact.The inherent deficency of vehicle automotive wheels tire, while running at high speed in air pressure deficiency (pressure of tire is lower than standard tire pressure) situation, along with the decline of tire pressure, the friction on tire and ground is multiplied, and in automobile tire, gas temperature and carcass temperature sharply raise, tire deliquescing, intensity sharply declines, and automobile tire internal gas pressure raises, in this case, the vehicle of running at high speed, just likely causes blowing out.If deficency (pressure of tire is lower than standard tire pressure) in vehicle automotive wheels tire, in the not enough situation of air pressure, run at a low speed for a long time in long process, automotive wheels tire both sides crimping repeatedly, cause automotive wheels tire two sides intensity to decline gradually, bury the hidden danger of blowing out, and incubation period is long, disguised large, harmfulness is strong, when vehicle high-speed driving or automotive wheels tire internal gas pressure suddenly change afterwards, just likely causes blowing out; Automotive wheels tire internal gas pressure is unstable, when vehicle travels under automotive wheels tire air pressure normal temperature standard tire pressure condition.Due to the variation of environment temperature, the variation of road speed, all will cause wheel tyre tire pressure to change--and environment temperature declines, and road speed declines, and automotive wheels pressure of tire declines, lower than standard tire pressure; Environment temperature raises, and road speed increases, and in automotive wheels tire, gas temperature raises, and automotive wheels pressure of tire raises, and tire pressure is above standard; Particularly under summer high temperature environment, automotive wheels is at high temperature, high pressure, automotive wheels tire sealant aging or wearing and tearing the anxious easily explosion of automotive wheels tire, broken tire in the time running at high speed.
In sum: the traffic accident of losing heart rapidly, blow out of automotive wheels tire occurs vehicle is in the process of moving to cause the pernicious motor traffic accidents of the maximum of casualties and property loss, producing reason has three: one, and automotive wheels tire is pierced through tire by sharp object and causes automotive wheels to be lost heart rapidly; The 2nd, the variation of environment temperature, causes air gas media expansion and contraction in automotive wheels tire, causes the tire pressure of automotive wheels tire raise or reduce, and exceeds standard tire pressure scope and causes blowing out; The 3rd, vehicle is run at high speed for a long time, particularly in summer high temperature automotive wheels in season, air gas medium basal temperature is high, vehicle run at high speed for a long time automotive wheels tire and ground friction tire temperature rise (can surpass 120 DEG C), cause air gas media expansion in automotive wheels tire, cause the tire pressure of automotive wheels tire to raise, exceed standard tire pressure scope and cause blowing out.
For addressing the above problem, there is method and the device of some automotive wheels tyre pricking proofs, leakproof recent years, the high molecule sealing materials of automotive wheels tyre pricking proof, leakproof.For example Chinese invention patent CN1935894A and CN101381503A disclose a kind of for the manufacture of macromolecular material anti-tie, leakproof; Chinese invention patent CN101037077A, CN1931910A, CN1803482A, CN1303409A disclose respectively that a kind of different manufacture is anti-tie, the method for puncture-proof tire; The support of safety traffic after Chinese utility model patent CN201346963Y, patent of invention CN101497297A disclose respectively a kind of different automotive wheels and blow out, above-mentioned patent does not all possess automotive wheels tire anti-explosion performance, only has the function of automotive wheels tyre pricking proof, leakproof; Open a kind of solid shellproof (explosion-proof) tire of number of patent application 201110050718.8, it and automotive hub are combined into shellproof (shellproof) automotive wheels, there is not automotive wheels tyre explosion problem, but exist flexibility, ride comfort performance poor, be not suitable with passenger vehicle, car and delivery personnel's vehicle, the vehicle that only adapts to carry cargo uses.
