Abstract
The utility model relates to an anti-stab run-flat tire. The anti-stab run-flat tire comprises a tire body, wherein a hot melt adhesive layer which is 0.5-4.5mm thick is uniformly arranged on the inner surface of the tire body; the hot melt adhesive layer covers the whole crown and extends to first kerbing ribs of the tire along the tire shoulder. The anti-stab run-flat tire is resistant to stab, prevents air leakage, not only can effectively reduce the traffic accidents caused by flat tire and the like but also has the functions of improving the driving safety, avoiding changing, repairing tires and improving the driving efficiency; the tire air tightness is improved; the deviation of dynamic balance is reduced; the driving resistance of the tire is reduced, thus reducing consumption and saving fuel; the anti-stab run-flat tire has superstrong temperature adaptability and is not worried about high-speed driving; the tire noise in the driving process is reduced; wear is reduced and the service life of the tire is prolonged.
Description
Technical field
The utility model relates to a kind of tire, especially relates to a kind of anti-puncture safety tyre.
Background technology
Along with developing rapidly of auto-industry, being gradually improved of traffic route network, to improving the performance of motor vehicle tire, develop safe, durable, product has become one of important brainstorm project of current research and production department at a low price at a high speed.According to the incomplete statistics of relevant professional institution, there is potential safety hazard in 95% above motor tire, 60% pressure of tire mal, there is nail at 37% above tyre crown position or stabs, the traffic accident of domestic express highway 70% causes by tire hidden danger, and the death by accident high rate of blowing out when automobile travels more than 120km/h speed reaches 100%.High-speed tire is blown out has become the large arch-criminal of vehicle safety accident four with furious driving, fatigue driving, drunken driving.It is startling that traffic accident is made us, and tire has become automotive safety Dai-ichi Mutual Life Insurance.According to now, to tyre performance analysis, need to further improve every technology, the economy index of tire, emphasis is explosion-proof, the anti-gas-leak problem that solves tire, and the research and development of safety tyre more and more cause the attention of manufacturer with production.
Safety tyre is called again " zero pressure type ", and its English is run-flat tire, has meant the tire that can also walk flat, and the literal translation of industry custom is " Runflat tire ".Conventional tyre suffers after foreign object puncture, and gas leakage very soon, sidewall then occurred and stay before this, and tyre bead departs from wheel rim, gently cannot continue to travel, heavy cause vehicle to topple.By comparison, safety tyre, after suffering puncture, can not leak gas or leak gas and be very slow, can keep the profile that travels, and tyre bead is still fixed on wheel rim, thereby assurance automobile can be stablized and travel for a long time or temporarily.Automobile is loaded onto after this tire, and not only safety performance improves greatly, and no longer needs carrying about standby tire.
Existing safety tyre, although there has been technically certain improvement, with reference to Fig. 1, is provided with coating 2 to carcass 1 inside face of tire,, from technical performance aspect, mainly also there is following defect: (1) coat thickness homogeneity can not guarantee; Existing technique often adopts centrifugal action that coating is distributed at tire inner surface, and this technique is easy to cause the thin phenomenon in coating thick middle both sides; Occur that sometimes interior thickness has reached 10～15mm, and thickness of two sides only has the phenomenon of 1～2mm; (2) the resistance to thermal adaptability of coating is limited, and Applicable temperature interval is less, and application is subject to regional restriction; (3) it is poor that the irregularity of coating has caused the dynamic balance of car body, and noise reduction is poor, and traveling comfort is not good; (4) glue consumption is large, thick coating, poor radiation; (5) tire internal coating tack is poor, and Using Life of Tyre is relatively short, can not adapt to high vehicle speeds demand; (6) narrow application range, product specification limited amount, can not meet all types of user demand.
Utility model content
The deficiency existing in order to overcome prior art, the utility model relates to that a kind of Fabrication procedure is simple, internal coating good uniformity, coating is thin, thermal diffusivity good, anti-stab, anti-gas-leak is effective safety tyre.
A puncture safety tyre, comprises carcass, is evenly provided with one deck hot melt adhesive layer on described carcass inside face, and the thickness of described hot melt adhesive layer is 0.5～4.5mm.
Preferably, the thickness of described hot melt adhesive layer is 2.5～3.5mm.
Preferably, the scope of described hot melt adhesive layer setting be crown all and extend to tire article one kerbing rib to tire shoulder direction.
Preferably, described tire carcass limit portion and interior thickness differ 0.1mm.
The utility model tire is applied widely, can be used for storage battery car, motor bike, car, gently card or truck; Above-mentioned tire construction is inner tube free structure, wherein, truck tire can be selected steel wire and meridian line structure inner tube free, and passenger car tire can be selected semi-steel radial structure inner tube free, motor cycle tire can be selected oblique nylon structure inner tube free, and light truck tire can be selected half steel structure inner tube free.
The beneficial effects of the utility model are:
(1) improve original tyre lunge-proof, leak resistance, can save time in order to avoid tire patching, do not change tire, improve driving efficiency and safety;
(2) good uniformity, coating is thin, and thermal diffusivity is good, lightweight;
(3) effectively dwindle tire dynamic and balance deviation, there is good noise elimination effect, can alleviate vibrations and noise in Vehicle Driving Cycle, improve Vehicle Driving Cycle traveling comfort;
(4) improve tyre air tightness, reduce rolling resistance, thereby reduce oil consumption, realize energy-conservation;
(5) tack is good, and heat stability is good, and internal coating can slow down wear on tyres, extends tire normal service life;
(6) can be applicable to the tire of various brands, specification, model on market, can meet all types of user demand.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of existing safety tyre.
Fig. 2 is section structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
With reference to Fig. 2, a kind of anti-puncture safety tyre, comprises carcass 3, on described carcass 3 inside faces, is evenly provided with one deck hot melt adhesive layer 4, described hot melt adhesive layer 4 scope be crown all and extend to tire article one kerbing rib 5 to tire shoulder direction.The thickness of described hot melt adhesive layer 4 is 2.5mm.
The utility model is at the hot melt adhesive layer 4 of tire inner wall, and coat thickness is even, and tyre beads portion is consistent with interior thickness, positive and negative 0.1mm.
With reference to Fig. 2, a kind of anti-puncture safety tyre, comprises carcass 3, on described carcass 3 inside faces, is evenly provided with one deck hot melt adhesive layer 4, described hot melt adhesive layer 4 scope be crown all and extend to tire article one kerbing rib 5 to tire shoulder direction.The thickness of described hot melt adhesive layer 4 is 3.5mm.
