Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically to an all-steel radial tire that avoids shoulder damage. Background Technology
[0002] Radial tires are a type of tire structure, distinct from bias-ply tires, arched tires, and adjustable-pressure tires. They are commonly known as "steel-belted tires." During the production and use of radial tires, the tire shoulder is prone to exposed threads, rendering the tire unusable. Furthermore, the tires produce excessive noise during use, negatively impacting the user experience.
[0003] In the prior art, the utility model patent with announcement number CN217672006U discloses a low-profile, wide-base all-steel radial tire, which includes an all-steel radial tire with an inclined rubber ring inside and an arc-shaped rubber ring bonded to the inner wall of the all-steel radial tire above the inclined rubber ring.
[0004] Regarding the aforementioned solutions, the use of arc-shaped rubber rings, soft layers, reinforcing layers, base layers, adhesive blocks, and inclined rubber rings addresses the issue of easy damage when tire pressure is low. However, these solutions are relatively limited in function and cannot adequately protect vulnerable areas such as the tire shoulder, nor can they address tire noise. Utility Model Content
[0005] The purpose of this invention is to provide an all-steel radial tire that avoids shoulder damage, thereby solving the technical problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an all-steel radial tire that avoids shoulder damage, comprising a tire body and a carcass layer, wherein the tire body includes a tread pattern fixedly disposed on the outer side of the tire body, and a tread groove is further provided between the tread pattern and the tire body; a shoulder is also fixedly disposed at both ends of the side of the tire body; a carcass layer is also fixedly disposed on the inner side of the tire body; a buffer rubber pad for buffering external pressure is fixedly disposed on the inner side of the carcass layer; a support component for providing support space on the inner side of the tire body is fixedly disposed on the inner side of the tire body; a buffer component is also fixedly disposed on the inner side of the support component, and an absorbent component is also fixedly disposed on the inner side of the buffer component.
[0007] Preferably, the support component includes a carcass layer fixedly disposed inside the tire body, and a tread base rubber is also fixedly disposed inside the carcass layer.
[0008] Preferably, the buffer component includes multiple sets of buffer rubber pads fixedly disposed between the tire body and the tire carcass layer, and multiple sets of hollow buffer rings are also fixedly disposed at both ends of the buffer rubber pads, and the multiple sets of hollow buffer rings are fixedly disposed between the tire carcass layer and the tire shoulder.
[0009] Preferably, the buffer rubber pad is elliptical on the outside and hollow inside, which can buffer the deformation of the pressure on the upper tire crown.
[0010] Preferably, the hollow buffer ring is circular on the outside and hollow on the inside, which buffers external impact pressure and prevents tire shoulder bursting.
[0011] Preferably, the absorbing component includes a gradient absorbing pad fixedly disposed at the rear end of the buffer rubber pad, and a sound-absorbing sponge is also fixedly disposed at the rear end of the gradient absorbing pad.
[0012] Preferably, the gradient absorption pad is hollow inside and has a gradually varying thickness on the outside.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the tire is subjected to external compression and impact during vehicle operation, the buffer rubber pad can buffer the pressure on the tire crown by deforming through the internal elliptical hollow compression, which can effectively improve the buffering effect of the tire crown. In addition, the circular hollow buffer ring can withstand more pressure and can effectively work with the buffer rubber pad to prevent tire shoulder bursting. The gradient absorption pad adopts a gradient thickness setting to reduce stress concentration in the tire shoulder area and avoid delamination due to excessive deformation. At the same time, it can buffer the impact energy between the buffer rubber pad and the gradient absorption pad, improve the tire's impact resistance, reduce the possibility of tire shoulder damage due to impact, and the sound-absorbing sponge can quickly absorb the tire noise generated during driving, reducing noise during driving.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-3 The present invention proposes an all-steel radial tire that avoids tire shoulder damage, comprising a tire body 1 and a tire carcass layer 21.
[0021] The tire body 1 includes a tread pattern 11 fixedly disposed on the outer side of the tire body 1, and a tread groove 12 is also provided between the tread pattern 11 and the tire body 1. Tire shoulders 13 are also fixedly disposed at both ends of the side of the tire body 1. A carcass layer 21 is also fixedly disposed on the inner side of the tire body 1, and a buffer rubber pad 31 for buffering external pressure is fixedly disposed on the inner side of the carcass layer 21.
[0022] Specifically, the tire body 1 and the tire carcass layer 21 provide a closed space for placing and fixing the cushioning rubber pad 31 and the gradient absorption pad 41, which can effectively buffer the impact force on the tread grooves 12 and the tire shoulder 13 on the side of the tire body 1.
[0023] like Figures 1-3 As shown, the support component 2 includes a carcass layer 21 fixedly disposed inside the tire body 1, and a tread base rubber 22 is also fixedly disposed inside the carcass layer 21.
[0024] Specifically, the tire body 1 and the tire carcass layer 21 can form a closed body, while the inner tread base rubber 22 fixes the buffer rubber pad 31 and the gradient absorption pad 41, etc.
[0025] exist Figures 1-2In this design, the buffer component 3 includes multiple sets of buffer rubber pads 31 fixedly disposed between the tire body 1 and the tire carcass layer 21. Multiple sets of hollow buffer rings 32 are also fixedly disposed at both ends of the buffer rubber pads 31, and these hollow buffer rings 32 are fixedly disposed between the tire carcass layer 21 and the tire shoulder 13. Specifically, the buffer rubber pads 31 are elliptical on the outside and hollow on the inside. When subjected to pressure from the ground and external sources, they can buffer the pressure on the tire crown by compressing the hollow elliptical structure internally, effectively improving the buffering effect of the tire crown.
[0026] like Figures 1-2 As shown, the hollow buffer ring 32 is circular on the outside and hollow inside, which buffers external impact pressure and prevents the tire shoulder 13 from bursting. Specifically, the hollow buffer ring 32 is circular and hollow, and it buffers the deformation caused by external impact pressure. The hollow interior of the circular buffer ring 32 can withstand more pressure, and at the same time, it can effectively work with the buffer rubber pad 31 to prevent the tire shoulder 13 from bursting.
[0027] like Figure 1 and Figure 4 As shown, the absorbing component 4 includes a gradient absorbing pad 41 fixedly disposed at the rear end of the buffer rubber pad 31, and a sound-absorbing sponge 42 is also fixedly disposed at the rear end of the gradient absorbing pad 41. The gradient absorbing pad 41 is hollow inside and has a gradually varying thickness on the outside. Specifically, the gradient absorbing pad 41 adopts a gradually varying thickness to reduce stress concentration at the tire shoulder 13, avoid delamination due to excessive deformation, and at the same time, it can buffer the impact energy between the buffer rubber pad 31 and the gradient absorbing pad 41, improve the tire's impact resistance, reduce the possibility of damage to the tire shoulder 13 due to impact, and the sound-absorbing sponge 42 can quickly absorb tire noise generated during driving, reducing noise during driving.
[0028] When the tire is subjected to external pressure and impact during driving, the buffer rubber pad 31, with its outer ellipse and hollow interior, can buffer the pressure on the tire crown by deforming through the internal elliptical hollow structure, effectively improving the buffering effect of the tire crown. The hollow buffer ring 32, with its circular hollow structure, also buffers the external impact pressure by deforming. The circular hollow interior of the buffer ring 32 can withstand more pressure and effectively works with the buffer rubber pad 31 to prevent the tire shoulder 13 from bursting. The gradient absorption pad 41, with its gradient thickness design, reduces stress concentration at the tire shoulder 13, preventing delamination due to excessive deformation. It also allows the impact energy to be buffered between the buffer rubber pad 31 and the gradient absorption pad 41, improving the tire's impact resistance and reducing the possibility of damage to the tire shoulder 13 due to impact. Furthermore, the sound-absorbing sponge 42 can quickly absorb tire noise generated during driving, reducing noise levels during driving.
[0029] Electrical equipment is safely powered by an external power source and controlled through a control box.
