Description

A kind of sidewall depressed trouble-proof tire

Technical field

The present invention relates to a kind of trouble-proof tire, and in particular to a kind of sidewall depressed trouble-proof tire.

Background technology

Relative to tubed tyre, tubeless tyre is the advantage of vacuum tyre it is obvious that one is that vacuum tyre compares conventional tires Formula tire is much thick, and appearance tension force increases after inflation, and certain pressure is formed in inner surface, the self-styled energy to cut is improved Power, once puncturing, gas has all been let out in moment unlike common tire, can continue the regular hour, will not bring direction The moment of disk is out of control, complete when having ensured high speed traveling；Since two be without the inner tube of a tyre, before vehicle high-speed inside vacuum tyre Variable quantity is small when entering, and can keep preferable riding stability and less friction, it is evident that be conducive to the absorption of jerk With the raising of speed, comfortableness, stability are all more far better than using common tire；Three be that vacuum tyre has lacked inner tube of a tyre opposed configuration It is simpler, while the life-span that vacuum tyre is used also increases, abrasion and the heat produced when running at high speed can be reduced in traveling Amount is lower, radiating is more preferable.

Nowadays, pneumatic tyre without inner tube has been widely used for small-sized ride-on vehicles, however be punctured in tire, air pressure not Enough or without under barometric information, existing conventional tubeless tyre (as shown in Figure 1), which remains, can not continue to travel or take turns Tire sidewall gross distortion and the problems such as cause the damage of sidewall cord and scrap.

Therefore, those skilled in the art are directed to developing a kind of relatively low, the safe and reliable sidewall depression of simple in construction, cost Formula trouble-proof tire, can realize the certain distance normally travel after tyre explosion, at the same reduce cause the damage of sidewall cord can Can, so as to greatly improve the security of tire, stability and service life.

The content of the invention

Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of sidewall depressed Explosion-proof wheel Tire, with simple in construction, cost it is relatively low, it is safe and reliable the features such as, sidewall is effectively improved by the optimization design of sidewall structure Performance is overally supported, so as to greatly improve the security of tire, stability and service life.

Technical scheme：To achieve the above object, the technical solution adopted by the present invention is：

A kind of sidewall depressed trouble-proof tire, including wheel rim and the cover tire being socketed on wheel rim；

Wherein, the section structure of the cover tire includes crown zone, the sidewall area of cover tire both sides, the crown zone two at the top of cover tire The shoulder area of lateral sidewall area transition and the bead region of sidewall area bottom, and bead region is installed on wheel rim；The sidewall area is adopted Use at the top of overall concave design, and sidewall area with shoulder area connecting portion and sidewall area bottom with wheel rim connecting portion using raised Structure design.

So integrally it is recessed by using sidewall, upper and lower ends thicken raised structure, effectively increases above and below sidewall Support performance, be punctured in tire, air pressure is not enough or without barometric information under, the trouble-proof tire still can carry out 3000-5000 The normally travel of rice, while reduce the possibility for causing the damage of sidewall cord, substantially increase the security of tire, stability and Service life.

It is preferred that, the cover tire includes the inner lining air barrier, casingply, buffering belt set gradually from inside to outside And tread rubber layer, and bead region is provided with the bcad seats of fixed casingply；The casingply is extended by crown zone To bead region and outwards wind bcad seats in bead region and realize fixation, and buffering belt is arranged at the carcass ply of crown zone Between layer and tread rubber layer；The tread rubber layer of the sidewall area thickeies raised structure using overall depression, upper and lower ends, It is simple in construction and economical and practical so as to effectively improve the support performance above and below sidewall.

It is preferred that, the inner lining air barrier is made up of airtight rubber, to realize the sealing of tire.

It is preferred that, in order to ensure the intensity and stability of tire, to bear strong vibrations and impact, the carcass Layer of cloth and buffering belt include at least one cross-ply being made up of gluing cord arranged side by side, and the cord is including organic Fiber cord and wire.

It is preferred that, sidewall steel wire floor is provided between the sidewall area casingply and tread rubber layer, is effectively improved The integrated support performance on sidewall, while realize the protection to sidewall cord.

It is preferred that, the turned up portion of the casingply is extended on the inside of the buffering belt of crown zone, to ensure carcass Effective fixation of casing ply, while improving the support performance on sidewall.

It is preferred that, the bulge-structure of the sidewall area bottom is covered on edge of rim position, prevents cover tire from deviating from wheel rim While realize the protection to the edge of rim, add the service life of tire.

Beneficial effect：A kind of sidewall depressed trouble-proof tire that the present invention is provided, relative to prior art, with following excellent Point：1st, the integrated support performance on sidewall is effectively improved by the optimization design of sidewall structure, is realized certain after tyre explosion Apart from normally travel, while reduce the possibility for causing the damage of sidewall cord, so as to substantially increase the security of tire, stably Property and service life；2nd, simple in construction, cost is relatively low, safe and reliable, while will not dramatically increase the weight of tire to cause pair Oil consumption and stability are impacted, with stronger practicality.
