Embodiment 1

[0054] A kind of inflatable run-flat tire of the present embodiment, as figure 1 , figure 2 with Figure 5 As shown, it includes a tire 1, which is characterized in that: the tire 1 is provided with an inner cavity 10, and the surface of the inner cavity 10 is surrounded by spiral ribs.

[0055] There are generally four reasons for tire blowouts. One is tire air leakage, which is caused by the tire itself being damaged or punctured. The other is that the tire pressure is too high. High-speed driving causes the temperature of the tire to rise and cannot dissipate heat in time. The air pressure in the tire will increase, resulting in tire deformation and blowout; the third is that the tire air pressure is insufficient, which may easily cause a large resonance force, and may cause the tire wall to burst when turning; the fourth is the performance of the tire itself, and the balance of tire manufacturing is not enough The main reason for the accident caused by a tire blowout is...

Embodiment 2

[0060] The inflatable run-flat tire of this embodiment is further improved on the basis of Embodiment 1, and the spiral ridges circle around the central axis 13 of the inner cavity in the circular direction on the surface of the inner cavity 10 to cover the inner cavity 10 for a week .

[0061] Such as image 3 As shown, the embossed pattern is spirally arranged on the surface of the inner cavity 10 in the manner shown in the figure. While enhancing the heat dissipation effect and eliminating the structural stress, the embossed pattern surrounds the inner cavity 10 of the tire like a spring, forming a spring skeleton against the inner cavity 10. It plays a certain supporting role. When the tire is punctured by external force, under the action of the spiral ribs arranged in this embodiment, the threads near the puncture hole evenly disperse the force generated during the puncture, preventing the tire from being punctured. When it breaks, it deforms suddenly, and the helical ri...

Embodiment 3

[0063] The inflatable run-flat tire of this embodiment is further improved on the basis of Embodiment 2, and the surface of the inner cavity 10 is provided with at least one spiral rib.

[0064] In the inflatable run-flat tire of this embodiment, the strength of the surface of the inner cavity 10 is further strengthened by providing a plurality of non-intersecting spiral ribs on the surface of the inner cavity 10, so as to enhance the anti-deformation ability of the tire when it is punctured or air leaks ; Multiple inner cavities 10 can also be set, and the surface of each inner cavity 10 is provided with spiral reliefs to achieve the same effect.

[0065] The inflatable explosion-proof tire of this embodiment has higher strength and stronger tire explosion-proof ability, but the manufacturing cost is increased. The inflatable explosion-proof tire of this embodiment can also be installed and used without inflation, and the spiral relief can be used. Support the carcass and pre...

Abstract

The invention discloses an inflatable anti-explosion tire and a processing method thereof, and belongs to the field of tires. The inflatable anti-explosion tire comprises a tire body, an inner cavityis formed in the tire body, and spiral convex grains are arranged around the surface of the inner cavity. The spiral convex grains are wound around the center axis of the inner cavity in the annular direction of the surface of the inner cavity for a circle. Anti-pricking holes are formed between the tire surface of the tire body and the inner cavity in the direction of the center axis of the innercavity. According to the inflatable anti-explosion tire, the spiral convex grains are arranged on the surface of the inner cavity of the tire body, the surface structure of the inner cavity of the tire body is changed, the specific surface area is increased, framework stress is eliminated, the heat exchange effect is enhanced, the anti-explosion performance requirement is met, and the tire weightis not increased; by means of the processing method, the tire can be integrally formed, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of tires, in particular to an inflatable run-flat tire and a processing method thereof. Background technique [0002] In recent years, the rapid development of the rubber industry has provided a broad market space for the tire industry, and various tire products have emerged in an endless stream. With the improvement of people's economic life, cars have also become a standing means of transportation, which brings great convenience to people's lives. At the same time, the accidents caused by wheel blowouts are also increasing. When the car is running at high speed, for tires with or without tubes, there are long-term wear and tear of the tire itself and the weight of the tire bearing the car body is transformed into internal damage. Air pressure, when the tire rotates rapidly and collides with the ground at high speed, the gas movement in the tire generates high pressure locally, and the outward pressure inside the tir...
