Description

Puncture-proof and explosion-proof run-flat tire

Technical Field

The utility model relates to a tire field, specific prevent puncture explosion-proof run-flat tire that loses heart that says so.

Background

With the advent of automobiles, pneumatic tires have been widely developed, and pneumatic tires have advantages of good cushioning properties, small rolling resistance, and the like. However, the pneumatic tire inevitably has potential safety hazards such as puncture by foreign objects, tire burst, no air or lack of air in the using process, which causes troubles and serious traffic accidents, so the tire has good puncture and explosion preventing functions, various puncture and explosion preventing tires or puncture preventing tires have been commercialized for many years, the tire only has one function, and the two cannot be effectively combined, and the existing tire has to be improved in this aspect.

Disclosure of Invention

The utility model discloses to the not enough of above existence, provide a prevent puncture explosion-proof tire for disappointing, this application has stronger thorn function of preventing, and the tire can be when not having gas or tire pressure low excessively still guarantee the function that vehicle safety, "steadily" goes simultaneously.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a prevent stinging explosion-proof run-flat tire that loses heart, includes the child hat, and child hat both ends are the tire shoulder, and the side of tire shoulder place is connected with the side wall, and the lower extreme of side wall is connected with the child toe, and the side wall outside is equipped with tire loading line, tire loading line includes the protruding face of outside extension, child hat outside-in includes tread rubber, first casing ply, second casing ply and child in proper order, and characterized by is equipped with in the child hat prevents the thorn layer, prevent that the thorn layer is the one deck at least, prevent that the thorn layer sets up between tread rubber, first casing ply, second casing ply and child in arbitrary adjacent two-layer.

Further, the anti-stab layer is one or more of high-density high-strength steel wire canvas or cord fabric, chemical fiber canvas or cord fabric, and natural wire canvas or cord fabric.

Further, the width of the puncture-proof layer extends to the inner layer of the tire shoulder, the tire side or the raised surface.

Further, the puncture-proof layer is arranged between the tread rubber and the first cord fabric layer.

Further, the stab-resistant layer is disposed between the first ply and the second ply.

Further, the puncture-proof layer is arranged between the second cord fabric layer and the tire liner.

The beneficial effect of this application does:

the utility model relates to a prevent flat tire that loses heart of thorn blast proof increases puncture-proof layer in the tire child hat, and this layer has high anti thorn performance, can play the effect that prevents the tire and be pricked by hard thing in the tire traveles, consequently can realize that the tire prevents thorn performance, and production simple process simultaneously, convenient to use, effectual.

Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

the utility model provides a prevent flat tire that loses heart of thorn blast proof, includes

child hat

1, and 1 both ends of child hat are

tire shoulder

2, and 2 place sides of tire shoulder are connected with side wall 3, and the lower extreme of side wall 3 is connected with child toe 5, and the 3 outsides of side wall are equipped with the tire loading line, the tire loading line includes the bellied face 4 of outside extension, child hat outside-in includes tread rubber 11, first casing ply 13, second casing ply 14 and child in proper order 12, characterized by is equipped with puncture-proof layer 15 in the child hat 1, puncture-proof layer 15 is the one deck at least, puncture-proof layer 15 sets up between tread rubber 11, first casing ply 13,

second casing ply

14 and 12 arbitrary adjacent two-layers in the child.

Further, the stab-resistant layer 15 is one or more of high-density high-strength steel wire canvas or cord fabric, chemical fiber canvas or cord fabric, and natural wire canvas or cord fabric.

Further, the width of the stab-resistant layer 15 extends to the inner layer of the shoulder 2, the sidewall 3 or the raised face 4.

In embodiment 1, the anti-puncturing layer 15 is disposed between the tread rubber 11 and the second ply 14, which has the advantages of reducing deformation of the tread 1, reducing hysteresis loss, reducing rolling resistance, and being more green and environment-friendly.

Embodiment 2, the anti-prick layer 15 is arranged between the first ply layer 13 and the second ply layer 14, and the advantage is that the generation and accumulation of heat caused by relative displacement between the first ply layer 13 and the second ply layer 14 in the running process of the tire can be reduced, and the service life of the tire can be prolonged.

Example 3, the anti-puncturing layer 15 is arranged between the first ply layer 13 and the inner tube 12, and the advantage is that the anti-puncturing layer 15 has a bidirectional bonding effect, and under the constraint of the first ply layer 13 and the second ply layer 14, the bonding degree of the first ply layer 13 and the inner tube 12 is increased, so that the risk of hollowing and delamination generated in the manufacturing and using processes of the tire can be effectively reduced.

In the above embodiment, the width of the puncture-proof layer 15 may extend to the tire shoulder 2, may extend to the tire sidewall 3, may also extend to the inner layer of the raised surface 4, and may be set according to the tire structure and the use condition, so as to play a better role in puncture-proof and explosion-proof.

Finally, it should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
