Abstract
The utility model provides a low temperature resistant pneumatic tire of high strength, including annular tread and around the side wall in tread inner wall both sides, tread and side wall are enclosed a synthetic inner tube of a tyre and are held the chamber, the inner tube of a tyre holds and is equipped with a ring -type in the chamber and aerifys the inner tube of a tyre, its characterized in that: the inboard of aerifing the inner tube of a tyre still is equipped with a springiness cushioning layer, the inner wall on springiness cushioning layer with the inner edge parallel and level on side wall. The utility model discloses structure and material to the tire are all optimized, and through setting up the springiness cushioning layer and optimizing its composition, the wearability, impact resistance and the cold resistance that make pneumatic tire obtain super present pneumatic tire far away are guaranteed the utility model discloses the tire still keeps higher stability and longer life in extreme environments, effectively improve the driving safety in the adverse circumstances.
Description
Technical field
The utility model relates to a kind of tire, is specifically related to a kind of air-inflation tyre of high-strength low-temperature-resistant.
Background technology
Existing air-inflation tyre is in order to obtain higher mechanical strength, stronger wear resistance; generally can carry out the process such as modification, thickening to tyre surface; the inflatable inner tube bearing high pressure with protection does not damage because of ectocine, the object realize maintaining inflatable inner tube working stability, ensureing traffic safety.But after the intensity of tyre surface and thickness reach certain scope, just cannot again promote, otherwise the comfort level that reduction carrier is taken by really up to the mark and blocked up tyre surface.In fact, even if at tyre surface through strengthening, when the inner tube of a tyre works in long-time, high strength and extreme environment, still very easily there is loss, as the inner tube of a tyre is brittle in extremely cold environment, finally blast because cannot tire pressure be born, have a strong impact on traffic safety.
Utility model content
In view of this, the utility model discloses a kind ofly has high mechanical properties, the air-inflation tyre of the environment that is applicable to extremely to tremble with fear.
The purpose of this utility model is achieved through the following technical solutions: a kind of air-inflation tyre of high-strength low-temperature-resistant, and comprise the tyre surface of annular and be looped around the sidewall of tyre surface inwall both sides, described tyre surface and sidewall enclose an inner tube of a tyre container cavity; Be provided with an annular plenum inner tube of a tyre in described inner tube of a tyre container cavity, the inner side of described inflatable inner tube is also provided with an elastic cord breaker, and the inwall of described elastic cord breaker is concordant with the inner edge on described sidewall.
In the utility model, sidewall and tyre surface all can adopt existing techniques in realizing, as arranged conventional anti-slip veins, adopt polysulphide rubbers to be prepared by raw material.Especially, the inner side of inflatable inner tube of the present utility model is also provided with elastic cord breaker.Existing inflatable inner tube its mostly directly contact with between wheel hub, under carrier cryogenic conditions during high-speed cruising, because tire pressure declines, the cooperate degree outside inflatable inner tube and wheel hub reduces, easily there is relative sliding between the two, finally wearing and tearing are produced to the inner side of inflatable inner tube.Especially prepare inflatable inner tube elastomeric material under cryogenic rigidity to increase and toughness reduces, increase further the intensity of loss.And sleet is easily infiltrated in the gap of wheel hub and inflatable inner tube in the winter time, the final ice quarrel that formed damages inflatable inner tube.Therefore the utility model is provided with elastic cord breaker in the inner side of inflatable inner tube especially, reduces wheel hub to the wearing and tearing of inflatable inner tube, and guarantee inflatable inner tube is thrown away under cryogenic can smooth working.
Further, described inflatable inner tube is 1:0.5-1:1.2 with the ratio of the thickness of described elastic cord breaker.
The thickness of described inflatable inner tube refers to the distance of outermost to its inner side.Thickness as elastic cord breaker is too low, easily causes pressing through squeegee action greatly in suffered by sidewall; And elastic buffer layer thickness is too high, then can reduce the buffering effect of tire, carrier too be jolted under steam and traveling comfort declines.Through the long-term checking of designer, when elastic buffer layer thickness is the 0.5-1.2 times of inflatable inner tube thickness, can effectively improve tire traveling comfort and traveling comfort.
In practical application, described elastic cord breaker can adopt flexible glue on the market or other known elastomeric materials to make.Preferably, its raw material of described elastic cord breaker comprises the buna-S of 70-90 part, 0.1-0.3 part potassium hydroxide, p-nitrophenol 0.01-3 part, polycarbonate 4-12 part, 0.2-0.7 part cupric oxide powder, disodium ethylene diamine tetraacetate 1-8 part, GMA 3-12 part, sodium nitrite 0.05-0.25 part and ferrous hydroxide 0.3-4.5 part by weight.
Described elastic cord breaker also can select commercially available buna-S to realize.Although elastic cord breaker can delay the wearing and tearing of inflatable inner tube, in extremely cold condition (-10--20 DEG C) environment, elastic cord breaker is still easily worn.When elastic cord breaker is worn to after to a certain degree, coordinating between its with wheel hub weakens and relative sliding easily occurs, and causes car skidding, equivalent risk of blowing out.And elastic cord breaker produces hard crackle to inflatable inner tube by wearing and tearing serious for generation by low temperature effect surface, especially under the road conditions of comparatively jolting, impact strength decline elastic cord breaker easily ruptures, and breach will be poked inflatable inner tube and make tire anergy.In view of this, the utility model is optimized the material of elastic cord breaker especially, improves the resistance to abrasion of elastic cord breaker on the one hand, strengthens elastic cord breaker low-temperature properties under cryogenic on the other hand.Particularly preferred, its raw material of described elastic cord breaker comprises the buna-S of 70-90 part, 0.1-0.3 part potassium hydroxide, p-nitrophenol 0.01-3 part, polycarbonate 4-12 part, 0.2-0.7 part cupric oxide powder, disodium ethylene diamine tetraacetate 1-8 part, GMA 3-12 part, sodium nitrite 0.05-0.25 part and ferrous hydroxide 0.3-4.5 part by weight.
Described buna-S can select any one commercially available prod to realize.Described potassium hydroxide, p-nitrophenol, polycarbonate, cupric oxide powder, disodium ethylene diamine tetraacetate, GMA, sodium nitrite and ferric hydroxide all can select existing techniques in realizing.
Potassium hydroxide and polycarbonate, GMA effectively can improve the tear resistance of buna-S when low temperature, prevent it from rupturing.Especially GMA wherein, when it lacks, the impact strength of elastic cord breaker obviously declines and easily bursts apart because impact.Disodium ethylene diamine tetraacetate, ferric hydroxide synergistic effectively can delay the process of moisture in inflatable inner tube surface solidification.Especially after adding sodium nitrite, the surperficial retentiveness of elastic cord breaker obviously raises, and makes moisture be attracted to elastic cord breaker place and cannot enter the lower inflatable inner tube surface of intensity, prevents moisture from forming the ice quarrel damage inner tube of a tyre further.P-nitrophenol and cupric oxide powder then can significantly improve the wear resistance of elastic cord breaker, the long-time change using its thickness that trace only occurs.Above-mentioned technique effect does not all have prior art to report.
The air-inflation tyre of a kind of high-strength low-temperature-resistant provided by the utility model, the structure and material of tire is all optimized, air-inflation tyre is made to obtain super existing airtyred resistance to abrasion far away, impact resistance and resistance to cold, ensure that the utility model tire still keeps higher stability and longer service life in extreme environment, effectively improve the traffic safety in harsh environment.
