[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. After searching, the prior art (application number: CN201822024728.4) records "an explosion-proof and wear-resistant tire, including a spoke, a bolt hole is arranged inside the spoke, a hub is installed on the outer wall of the spoke, a tire is installed on the outer wall of the hub, a high heat-resistant synthetic rubber tread is arranged on the outer wall of the tire, an anti-slip pattern is arranged on the outer wall of the high heat-resistant synthetic rubber tread, a thickened sidewall is arranged on the inner wall of the high heat-resistant synthetic rubber tread, an aluminum alloy strip is arranged inside the thickened sidewall, a buffer layer is arranged on the inner wall of the thickened sidewall, a steel wire ring belt is arranged on the inner wall of the buffer layer, a cord layer is arranged on the inner wall of the steel wire ring belt, a tire lip steel wire is arranged inside the cord layer, and an inner surface rubber is arranged on the inner wall of the cord layer. The utility model improves the explosion-proof and wear-resistant performance of the tire by arranging a thickened sidewall inside the tire and adding an aluminum alloy strip inside the thickened sidewall."

[0003] However, although the explosion-proof and wear-resistant tires in the prior art have achieved explosion-proof and wear-resistant effects, they still have some shortcomings: the existing explosion-proof and wear-resistant tires achieve the driving support effect after a tire burst by thickening the sidewalls and aluminum alloy strips, but the reinforced sidewalls are placed on the lower side of the tread, which has a poor supporting effect on the sidewalls, and the sidewalls are relatively weak parts of the tire, so the supporting effect is poor. At the same time, the aluminum alloy strips increase the mass of the tire and weaken the circumferential elasticity of the tire, making it inconvenient to remove the tire for replacement, and may affect the dynamic balance of the tire; secondly, the existing explosion-proof tires do not have good silent performance, resulting in a large tire noise during driving. Utility Model Content

[0004] In order to overcome the defects of the prior art, an explosion-proof and wear-resistant tire is provided to solve the problems of the existing explosion-proof and wear-resistant tires, such as heavy weight, poor supporting effect, and poor quietness.

[0005] To achieve the above-mentioned purpose, a explosion-proof and wear-resistant tire is provided, comprising: a tread, a sidewall auxiliary reinforcement layer and a soundproofing component, wherein a cap band winding layer, a steel belt layer and an edge belt layer are provided on the inner side of the tread, and a cord layer and an inner liner layer are provided on the inner side of the edge belt layer, and a tire bead assembly is connected to the inner edge of the inner liner layer, the sidewall auxiliary reinforcement layer is provided on the outer side of the cord layer, and an outer sidewall is provided on the outer side of the sidewall auxiliary reinforcement layer, and the sidewall auxiliary reinforcement layer comprises an outer polyurethane reinforcement layer and a solid hard rubber layer between the polyurethane reinforcement layers, the soundproofing component is bonded to the inner wall of the inner liner layer, and the soundproofing component comprises a sound-absorbing layer, and a heat-insulating cavity is provided between the sound-absorbing layers.

[0006] Furthermore, the outer edge of the tread is connected to the outer sidewall under vulcanization process conditions to form an integral structure, and the tread surface is provided with a pattern, and the tread is made of a highly heat-resistant synthetic rubber material.

[0007] Furthermore, the edge belt layer and the steel belt layer are made of the same material, and the edge belt layer is placed on the arc-shaped shoulders on both sides of the cord layer.

[0008] Furthermore, a sealing edge is provided on the outer side of the sound absorbing layer, and rubber columns are connected between the sound absorbing layers, and the rubber columns are placed in the heat insulation cavity.

[0009] Furthermore, rubber sealing films are provided at both ends of the rubber column, and the rubber sealing films are bonded to the inner side of the sound absorbing layer.

[0010] Furthermore, the sound absorbing layer is made of polyurethane foam, and an adhesive layer is provided on the inner side of the sound absorbing layer, and the adhesive layer is bonded to the inner side of the lining layer.

[0011] Furthermore, the tire bead assembly includes an apex rubber and a steel ring, and the steel ring is fused inside the apex rubber, and a sidewall reinforcement layer is connected to the inner side of the tire bead assembly.

[0012] The beneficial effects of the utility model are:

[0013] 1. The mechanical support strength of the tire sidewall is enhanced by using the auxiliary sidewall reinforcement layer arranged on the inner side of the outer sidewall, and the polyurethane reinforcement layer and solid hard rubber layer included in the auxiliary sidewall reinforcement layer. With the sidewall reinforcement layer, the driving support effect after a tire burst is achieved without increasing the weight of the tire. In addition, the use of aluminum alloy metal is abandoned, which avoids weakening the circumferential elasticity of the tire, facilitates tire replacement, and avoids the uneven weight distribution of the tire that may be caused by aluminum alloy metal, resulting in dynamic balance problems;

[0014] 2. The double-layer sound-absorbing layer included in the silent part is used to absorb the noise generated inside and outside the tire. At the same time, the heat insulation cavity has a sound insulation effect under the sealing conditions of the sealing edge and the rubber sealing film, so that the tire has the performance of sound insulation and noise reduction. In addition, through two independent edge belt layers and two overlapping steel belt layers, the vibration of the tire when driving on rough roads is effectively suppressed, thereby suppressing the unnecessary movement of the tire and further enhancing the effect of reducing road noise.

[0022] In this embodiment, the tread 1 and the inner structure, the sidewall auxiliary reinforcement layer 7 and the silent member 8 constitute the main structure of the explosion-proof and wear-resistant tire involved in this application.

At the same time, the tread 1 is made of a highly heat-resistant synthetic rubber material, which has heat-resistant and wear-resistant effects.

[0024] The sidewall reinforcement layer 10 adopts the sidewall reinforcement process under the existing technology, and is integrated with the inner liner 6 and the tire bead assembly 11 after the vulcanization process.

[0025] It should be noted that the silent component 8 does not participate in the green tire vulcanization process. After the green tire vulcanization is completed, it is connected to the inner wall of the tire by bonding, and the silent component 8 is an annular structure as a whole.

[0026] Specifically, the edge belt layer 4 and the steel belt layer 3 are made of the same material, and the edge belt layer 4 is placed on the arc-shaped shoulders on both sides of the carcass layer 5 .

It achieves the goal of strengthening the mechanical strength of explosion-proof support on the basis of existing explosion-proof and wear-resistant tire technology, while avoiding the use of metal materials, reducing the weight of the tire, and ensuring the dynamic balance of the tire. At the same time, on the basis of explosion-proof and wear-resistant, it increases the effect of sound absorption and noise reduction, thereby enhancing comfort during use.
