Abstract

The utility model relates to a safety burst-proof tyre, which is applied in the burst prevention of a tubeless tyre (high speed tyre) particularly. The safety burst-proof tyre avoids steel rings deforming and vehicles turning and maintains temporary running ability. Thus, the inner wall of the tubeless tyre is additionally provided with an annular solid rubber sub tyre, and the section forms a circle shape or an ellipse shape (or other shapes). When the tubeless tyre is deflated, the sub tyre can make the outer edge of the tyre and the ground separated from the steel rings, which avoids the steel rings being pressed and deforming or the vehicles losing balance and turning over because of the contact with the ground. Even if the air in the tyre is leaked out, the temporary running ability can still be maintained.

Description

Safety burst-proof tyre

The utility model relates to the improvement of automobile tyre.

Tire is mainly used in the total weight of support unit, borrows tire to contact with ground, the braking force the when propulsive effort of transmission driving vehicle and brake.In the prior art, tire is by unusual two classes that are divided into of structure, the one, tube tyre, promptly common tire; The 2nd, tubeless tire, i.e. performance tires.In two kinds of tires, tube tyre, as long as the inner tube of a tyre one is punctured, air just leaks immediately and disappears, and wheel is cannot moved; Tubeless tires because of its inwall has the airtight excellent neoprene of one deck, also has airtight high protective cover in the tire lip portion simultaneously; when tire is punctured; though have the function that delays to leak gas, if in time do not find gas leakage, it is excessive to leak gas; still can travel; if travel by force, steel ring directly touches ground, very easily causes Wheel Rim deformation; even in fast running, cause the vehicle lack of equilibrium and the accident of overturning, have a strong impact on traffic safety.

In order to overcome above-mentioned shortcoming, the utility model provides a kind of and can prevent effectively that tubeless tires from blowing out and cause the mother and child safety trouble-proof tire of Wheel Rim deformation even roll-over accident when losing heart.

Above-mentioned purpose of the present utility model reaches like this: promptly the inwall of tubeless tires set up one with one-body molded or adhere to inwall be toroidal and section is the sub-tire of circle, this sub-tire can be filled between steel ring and tire and the ground by pressurized when tyre explosion loses heart, avoid steel ring to be out of shape because of the kiss the earth pressurized, even air has been let out in the tire, still can keep its driveability.

The utility model adopts the following drawings:

Fig. 1 is the section plan of the utility model embodiment.

Fig. 2 is the three-dimensional cutaway view of the utility model embodiment.

Plan sketch when Fig. 3 blows out for the utility model embodiment.

Fig. 4 is the section plan of another embodiment of the utility model.

Below in conjunction with embodiment and accompanying drawing the utility model is further described:

Fig. 1 and Fig. 2 are respectively section plan and the three-dimensional cutaway view of the utility model embodiment, wherein tire 1 and steel ring 2 parts are identical with general tubeless tires, inwall 3 is the airtight excellent neoprene of one deck, and its tire lip portion 4 can keep good airtight with steel ring 2.The utility model is set up a circle cross section and is the solid sub-tire 5 of annular arrangement on the inwall 3 of tire 1, this sub-tire 5 is fixed in the inwall 3 of tire 1, can be when making and tire 1 one-body molded, can also fix by adhesive method.Sub-tire 5 is between outer rim 6, inwall 3 and the steel ring 2 of tire 1, and factor tire 5 is little with the width that tire 1 fixedly amplexiforms a little, is unlikely influenced generation vibrations and seismic wave is reached vehicle body.Factor tire 5 only is arranged at the segment space in the tire 1, and other parts still are filled with high pressure air in the tire 1, therefore can not influence tire flexibility, shock-proof effect and intensity etc.When 1 round sharp object of tire pierces through, when tire 1 inner air leaks to a certain degree, sub-tire 5 promptly contacts with steel ring 2, and be filled between tire 1, ground and the steel ring 2, as Fig. 3, this moment, sub-tire 5 was widened with the contact surface of steel ring 2 because of being subjected to the vehicle weight compressing, provided one simultaneously at interval, tire 1, ground are contacted with steel ring 2, can avoid steel ring 2 kiss the earth deformation in compressions or lack of equilibrium effectively and cause phenomenon such as overturning to take place.This moment, sub-tire 5 also can provide the ability of temporarily travelling, and repaired vehicle is left to suitable place.The section of the sub-tire 5 of the utility model is not limited in circle, and the vehicle of visual use, tyre kind and tyre width etc. suitably are changed to ellipse garden shape or other shapes.

As Fig. 4, when the utility model is applied to the steel ring of broad, can establish the curved bearing 7 of a ring in the outer rim of steel ring 2, the height at these bearing 7 two ends is lower than two ora terminalis 8 of steel ring 2, can be when the leakage of tire internal gas pressure be blown out, make sub-tire 5 just in time push driving fit in bearing 7 formed chases, make the unlikely invar circle of sub-tire width too big, and outwards skid off the disengaging steel ring.Look the actual needs of tire, steel ring, the height of bearing 7, shape also can suitably change.So except that can keeping sub-tire 5 not skid off the steel ring 2, but sub-tire 5 appropriate change size more to increase the spatial content of tire inner high voltage air, more reduces the influence to shock-proof effect.

Claims

1, a kind of mother and child safety trouble-proof tire, it is characterized in that: the inwall of tubeless tires set up one with one-body molded or adhere to inwall be toroidal and section is the sub-tire of circle, this sub-tire can be filled between steel ring and tire and the ground by pressurized when tyre explosion loses heart.

2, mother and child safety trouble-proof tire according to claim 1 is characterized in that the steel ring outer rim is provided with the curved bearing of a ring, and the height at bearing two ends is lower than two ora terminalis of steel ring, and this bearing falls to closing in its chase when being squeezed for sub-tire.
