Description

Technical Field

[0001] This utility model relates to the field of tires, and in particular to a high load-bearing and wear-resistant all-steel radial tire. Background Technology

[0002] A tire is a ring-shaped rubber product installed on the wheels of a vehicle or piece of machinery. Its main functions include supporting the weight of the vehicle body, transmitting driving and braking forces, absorbing vibrations generated during driving to improve driving comfort, and providing excellent grip to ensure driving safety.

[0003] With the continuous increase in national investment in infrastructure construction, the development of construction machinery has placed more stringent and personalized demands on the operating environment and load-bearing capacity of tires, becoming an important trend in the future development of the construction machinery field. Taking all-steel radial tires as an example, they are mainly used in long-distance transportation, have excellent load-bearing performance, are produced on a large scale, and have a wide range of applications, making them one of the important products in the tire industry. The continuous development of construction machinery has not only brought unprecedented market opportunities to tire manufacturers, but also placed higher demands on product quality, requiring tires to be able to adapt to complex and changing operating environments and meet customers' ever-increasing demands for wear resistance.

[0004] Generally speaking, all-steel radial tires emphasize strong load-bearing capacity during use, and the bead area is usually reinforced. However, this design often neglects the tire's wear resistance, which may lead to accelerated wear during actual use and thus affect the tire's service life.

[0005] Therefore, it is necessary to provide a high-load-bearing, wear-resistant all-steel radial tire to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the aforementioned technical problem of poor wear resistance in all-steel radial tires, this utility model provides a high-load-bearing and wear-resistant all-steel radial tire.

[0007] This utility model provides a high load-bearing and wear-resistant all-steel radial tire, comprising: a tire carcass, a steel cord layer fixedly connected inside the tire carcass, steel wire rings fixedly wrapped around both sides of the steel cord layer, a first belt layer fixedly disposed inside the tire carcass and located on the outer wall of the steel cord layer, a second belt layer fixedly connected to the outer wall of the first belt layer, a third belt layer fixedly connected to the outer wall of the second belt layer, and several reinforcing members evenly disposed on the wrapped sides of the steel cord layer to restrict the installation position of the steel wire rings on the steel cord layer.

[0008] Preferably, the tire carcass includes an inner liner fixedly connected to the inner wall of the steel cord layer, and a tire crown is provided on the outside of the inner liner. The tire crown is located on the side of the third belt layer away from the steel cord layer. Tire sidewalls are fixedly connected to both sides of the tire crown. The tire sidewalls are located on the side of the steel cord layer away from the inner liner. Wear-resistant rubber is fixedly connected between the tire sidewalls and the tire crown. The steel wire ring is located inside the wear-resistant rubber.

[0009] Preferably, the outer walls of the reverse wrapping areas on both sides of the steel wire cord fabric layer are fixedly connected with steel wire wrapping fabric, and the reinforcement parts penetrate through the steel wire wrapping fabric.

[0010] Preferably, the outer wall of the steel cord fabric layer is symmetrically fixed with tire shoulder pad rubber, and the two sides of the first belt layer, the second belt layer and the third belt layer are respectively located inside each tire shoulder pad rubber.

[0011] Preferably, the outer wall of the steel wire-covered fabric is fixedly connected to a nylon-covered fabric, and the reinforcing member penetrates through the nylon-covered fabric.

[0012] Preferably, a lower triangular adhesive is provided above the steel wire ring, and an upper triangular adhesive is provided above the lower triangular adhesive, with the reinforcing member passing through the lower triangular adhesive and the upper triangular adhesive.

[0013] Preferably, the reinforcement includes a reinforcing strip that passes through the lower triangular adhesive, the upper triangular adhesive, the steel wire cord layer, the steel wire covering, and the nylon covering. Both ends of the reinforcing strip are fixedly connected to limit pads, which are located on the outer wall of the nylon covering.

[0014] Compared with related technologies, the high load-bearing and wear-resistant all-steel radial tire provided by this utility model has the following beneficial effects:

[0015] 1. This high-load-bearing and wear-resistant all-steel radial tire improves wear resistance and extends tire life: The tire carcass design restricts the installation position of the steel cord layer. Steel wire rings are fixedly wrapped around both sides of the steel cord layer. The steel cord layer provides load-bearing capacity and impact resistance to the tire carcass, while the steel wire rings enhance its stability. The first, second, and third belt layers are sequentially positioned between the outer wall of the steel cord layer and the inner wall of the tire carcass. The third belt layer uses a zero-degree belt layer instead of the traditional third belt, ensuring greater wear resistance and comfort. The first belt layer is wider than the second belt layer, increasing the number of steel wires at the shoulder and reducing sway, effectively mitigating issues like groove cracking and crown bursts. This further improves tire wear resistance and extends tire life. Reinforced fasteners enhance the connection between the steel cord layer and the steel wire rings, further ensuring tire quality.

[0016] 2. This high-load-bearing and wear-resistant all-steel radial tire, through the combination of the inner liner, tire crown, sidewalls on both sides, and wear-resistant rubber between the inner liner and the sidewalls, can wrap the installed steel cord layer and belt layer. The steel cord wrapping can further enhance the stability of the steel cord layer wrapping the steel wire ring installation point, and the nylon wrapping can wrap and protect the outside of the steel cord wrapping. The shoulder pad rubber can separate the edges of the steel cord layer and the belt layer, maintain the flatness of the belt layer, and prevent wear between the steel cord layer and the belt layer.

[0017] 3. This high-load-bearing and wear-resistant all-steel radial tire features lower and upper triangular rubber bushings located inside the inverted area of ​​the steel cord fabric layer. The upper triangular rubber bushing supports the tire sidewall, ensuring the tire maintains a stable shape and structure during driving. The lower triangular rubber bushing provides support at the bead area and also facilitates a gradual transition. The reinforcing strip, in conjunction with the limiting pads at both ends, restricts the connection stability between the lower and upper triangular rubber bushings, the steel cord fabric layer, the steel cord covering, and the nylon covering.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 4A high-load-bearing and wear-resistant all-steel radial tire includes: a tire carcass 1, a steel cord layer 2 fixedly connected inside the tire carcass 1, steel wire rings 3 fixedly wrapped around both sides of the steel cord layer 2, a first belt layer 4 fixedly disposed inside the tire carcass 1 and located on the outer wall of the steel cord layer 2, a second belt layer 5 fixedly connected to the outer wall of the first belt layer 4, a third belt layer 6 fixedly connected to the outer wall of the second belt layer 5, and several reinforcing members 7 evenly disposed at the wrapped areas on both sides of the steel cord layer 2 to limit the installation position of the steel wire rings 3 on the steel cord layer 2.

[0025] In the specific implementation process, the tire carcass 1 set in the high load-bearing and wear-resistant all-steel radial tire can restrict the installation position of the steel cord layer 2. Steel wire rings 3 are fixedly wrapped inside both sides of the steel cord layer 2. The steel cord layer 2 can be made of high-strength steel wires arranged in a radial direction to provide load-bearing capacity and impact resistance for the tire carcass 1. The steel wire rings 3 can be made of multiple layers of steel wires and wrapped in the steel cord layer 2, which can enhance the stability of the tire carcass 1 during use.

[0026] Furthermore, a first belt layer 4, a second belt layer 5, and a third belt layer 6 are sequentially arranged on the outer wall of the steel cord layer 2. This application addresses the different operating environments of all-steel radial tires. This tire structure design is positioned for overload. The third belt layer 6 uses a zero-degree belt layer instead of the traditional third belt. Although the zero-degree belt layer is not as elastic as the traditional third belt, its stability and strength are greatly increased, thereby improving tire quality and wear resistance. At the same time, it can increase the tire's load-bearing capacity, making the tread more stable during driving. In order to further improve wear resistance, the width of the traditional first and second belts is replaced, making the width of the first belt layer 4 larger than that of the second belt layer 5. This increases the number of steel wires on the shoulder and reduces sway. This design fully considers the unique groove cracking and crown bursting problems of all-steel radial tires, thereby further improving the tire's wear resistance and extending its service life.

[0027] Furthermore, several reinforcing members 7 are evenly arranged at the reverse wrapping point of the steel cord layer 2 and the steel wire ring 3. The reinforcing members 7 can enhance the stability of the connection between the steel cord layer 2 and the steel wire ring 3. When this high load-bearing and wear-resistant all-steel radial tire is used, it can improve the quality of the tire, increase the load-bearing capacity of the tire, and effectively improve the problems of groove cracking and crown bursting. It also increases the wear resistance of the tread and extends the service life of the tire, making this application more conducive to practical use.

[0028] Specifically, it should be noted that: the zero-degree belt layer is a reinforcing layer in which steel cords are tightly arranged in the circumferential direction at an angle close to 0° (usually ≤3°). The core function of the zero-degree belt layer is to improve the rigidity of the tire crown and suppress tread deformation under high speed or overload, thereby reducing the risk of groove cracking. The traditional No. 3 belt is an abbreviation for the third belt layer in traditional all-steel radial tires. Its cord angle is usually 15°-5°. This layer mainly provides lateral support, but the multi-layer structure is prone to interlayer shear stress under heavy load, leading to the risk of crown burst.

[0029] refer to Figure 1 , Figure 2 and Figure 4 As shown, the tire carcass 1 includes an inner liner 101 fixedly connected to the inner wall of the steel cord layer 2. A tire crown 102 is provided on the outside of the inner liner 101. The tire crown 102 is located on the side of the third belt layer 6 away from the steel cord layer 2. Both sides of the tire crown 102 are fixedly connected to the tire sidewall 103. The tire sidewall 103 is located on the side of the steel cord layer 2 away from the inner liner 101. A wear-resistant rubber 104 is fixedly connected between the sidewall 103 away from the tire crown 102 and the inner liner 101. The steel wire ring 3 is located inside the wear-resistant rubber 104.

[0030] In the specific implementation process, the inner liner 101, the tire crown 102, the tire sidewalls on both sides 103 and the wear-resistant rubber 104 between the inner liner 101 and the tire sidewalls 103 can be used to wrap the installed steel cord fabric layer 2 and the belt layer, thereby restricting the installation position of the steel cord fabric layer 2 and the belt layer.

[0031] refer to Figure 2 and Figure 4 As shown, the outer walls of the reverse wrapping areas on both sides of the steel wire curtain layer 2 are fixedly connected with steel wire wrapping fabric 8, and the reinforcing parts 7 penetrate through the steel wire wrapping fabric 8.

[0032] In the specific implementation process, the steel wire wrapping cloth 8 can further enhance the stability of the steel wire cord layer 2 wrapping the steel wire ring 3 at the installation point, and the reinforcement 7 can also play a certain limiting role for the steel wire wrapping cloth 8.

[0033] refer to Figure 2 and Figure 3 As shown, the outer wall of the steel cord fabric layer 2 is symmetrically fixed with tire shoulder pad rubber 10, and the two sides of the first belt layer 4, the second belt layer 5 and the third belt layer 6 are respectively located inside each tire shoulder pad rubber 10.

[0034] In the specific implementation process, the shoulder pad rubber 10 can maintain the flatness of the belt layer and separate the steel cord layer 2 and the edge of the belt layer to prevent wear between the steel cord layer 2 and the belt layer.

[0035] refer to Figure 2 and Figure 4As shown, a nylon cloth 9 is fixedly connected to the outer wall of the steel wire cloth 8, and the reinforcement 7 penetrates the nylon cloth 9.

[0036] In the specific implementation process, the nylon wrapping cloth 9 can wrap the outside of the steel wire wrapping cloth 8, thereby providing a certain degree of protection for the steel wire wrapping cloth 8. Furthermore, the reinforcement 7 can restrict the installation position of the nylon wrapping cloth 9 on the outside of the steel wire wrapping cloth 8.

[0037] refer to Figure 2 and Figure 4 As shown, a lower triangular adhesive 11 is provided above the steel wire ring 3, and an upper triangular adhesive 12 is provided above the lower triangular adhesive 11. The reinforcement 7 passes through the lower triangular adhesive 11 and the upper triangular adhesive 12.

[0038] In the specific implementation process, the lower triangular rubber 11 and the upper triangular rubber 12 are both located inside the reverse wrapping part of the steel cord layer 2. The upper triangular rubber 12 can support the tire sidewall to ensure that the tire maintains a stable shape and structure during driving, and can play a transition role between the flexural area of ​​the tire sidewall 103 and the rigid steel wire ring 3 to prevent breakage caused by direct connection between soft and hard parts. The lower triangular rubber 11 can play a supporting role in the tire bead part, and can also play a role in slow transition. The reinforcement 7 is set through the lower triangular rubber 11 and the upper triangular rubber 12. The reinforcement 7 can restrict the installation position of the lower triangular rubber 11 and the upper triangular rubber 12 inside the steel cord layer 2.

[0039] refer to Figure 2 and Figure 4 As shown, the reinforcement component 7 includes a reinforcing strip 701, which passes through the lower triangular adhesive 11, the upper triangular adhesive 12, the steel wire cord fabric layer 2, the steel wire wrapped fabric 8, and the nylon wrapped fabric 9. Both ends of the reinforcing strip 701 are fixedly connected to limit pads 702, which are located on the outer wall of the nylon wrapped fabric 9.

[0040] In the specific implementation process, the reinforcing strip 701 and the limiting pad 702 can be made of rubber material with a certain elasticity. By the cooperation of the reinforcing strip 701 and the limiting pads 702 at both ends, the connection stability between the lower triangular rubber 11, the upper triangular rubber 12, the steel wire cord layer 2, the steel wire covering 8 and the nylon covering 9 can be restricted.

[0041] The working principle of the high load-bearing and wear-resistant all-steel radial tire provided by this utility model is as follows:

[0042] In use, the steel cord ply 2 is placed inside the tire carcass 1, and reverse-wrapped steel wire rings 3 are fixed on both sides of the steel cord ply 2. The steel cord ply 2 provides the tire carcass 1 with load-bearing capacity and impact resistance, while the steel wire rings 3 enhance the stability of the tire carcass 1. The first belt layer 4, the second belt layer 5, and the third belt layer 6 are sequentially placed between the outer wall of the steel cord ply 2 and the inner wall of the tire carcass 1. The third belt layer 6 uses a zero-degree belt layer instead of the traditional third belt. The zero-degree belt layer improves the tire's quality and makes the tire more wear-resistant, while also increasing the tire's load-bearing capacity. This design makes the tire tread more stable during driving. The width of the first belt layer 4 is larger than that of the second belt layer 5, which increases the number of steel wires in the shoulder and reduces sway. This effectively improves the problems of groove cracking and crown bursting, thereby further improving the tire's wear resistance and extending its service life. Several reinforcement members 7 are evenly arranged at the point where the steel cord layer 2 wraps around the steel wire ring 3. The reinforcement members 7 enhance the stability of the connection between the steel cord layer 2 and the steel wire ring 3, further ensuring tire quality and extending tire service life, making this application more conducive to practical use.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
