Description

Technical Field

[0001] This application relates to the field of tire technology, and in particular to a tire with sidewall warning. Background Technology

[0002] Traffic accidents are caused by a variety of factors, and tires, as the only part of a vehicle in contact with the ground, are frequently the cause of accidents due to tire damage. Therefore, tire safety is extremely important. Typically, the weakest point of a tire is the sidewall, which is also the most easily damaged part during use. After a tire sidewall is scratched, the user cannot determine whether the tire is at risk. Current technology does not provide a clear visual indication of the location of the tire damage after a sidewall scratch, nor does it warn of the severity of the damage or provide information indicating that replacement is necessary, thus affecting driving safety. Utility Model Content

[0003] This application proposes an optimized multi-composite sidewall design, which enhances the identifiability of the tire failure location after the tire is damaged, thereby alerting consumers and raising their awareness of tire safety.

[0004] This application includes: a tire with sidewall warning, comprising a tire body, a composite sidewall, a triangular rubber core, and a steel wire ring. The composite sidewall is located on the outside of the tire body and includes: an upper sidewall rubber, a lower sidewall rubber, a wear-resistant rubber, and a reinforcing layer. The lower sidewall rubber is laid inside the upper sidewall rubber. The upper and lower sidewall rubbers are different colors. Wear-resistant rubber extends sequentially from the lower end of the upper sidewall rubber. A reinforcing layer is laid inside the lower sidewall rubber. A transition layer is laid inside the reinforcing layer. The reinforcing layer extends downward to the wear-resistant rubber and is a double-layer integrated structure. A triangular rubber core and a steel wire ring are provided on the inner side between the two layers. The triangular rubber core is connected to the upper end of the steel wire ring.

[0005] Furthermore, the upper tire sidewall material comprises rubber, colorant, and anti-wear agent, wherein the colorant is black.

[0006] Furthermore, the lower tire sidewall material comprises rubber, colorant, and anti-wear agent, wherein the colorant is red.

[0007] Furthermore, the thickness 'a' of the upper tire sidewall rubber satisfies: a > 1 mm, and the thickness 'b' of the lower tire sidewall rubber satisfies: 1 mm ≤ b ≤ 7 mm.

[0008] Furthermore, the thickness of the wear-resistant rubber is the sum of the thickness of the upper tire sidewall rubber and the thickness of the lower tire sidewall rubber.

[0009] Furthermore, the reinforcing layer is also sprayed with reflective paint, and the adhesive of the reinforcing layer is yellow or purple.

[0010] Furthermore, the thickness c of the reinforcing layer satisfies: 3mm ≤ c ≤ 8mm.

[0011] Furthermore, the hardness values ​​of the upper sidewall rubber, lower sidewall rubber, and reinforcing layer in the composite tire sidewall are related as follows: the hardness value of the reinforcing layer > the hardness values ​​of the upper sidewall rubber and the lower sidewall rubber.

[0012] Furthermore, the upper end of the triangular core is bonded to the transition layers on both the inner and outer sides.

[0013] Furthermore, the height of the triangular rubber core is 13-22mm.

[0014] The beneficial effects of this application are as follows: This application provides a tire sidewall structure, which is covered with an upper sidewall rubber, a lower sidewall rubber and a reinforcing layer. Each layer of rubber is set with a different color. This structure can serve as a warning. When the tire sidewall is damaged, the driver can judge the extent of the tire damage based on the color of the exposed rubber after the damage, which can reduce the occurrence of traffic accidents.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] like Figures 1-2The tire shown includes a tire body 1, a composite sidewall 8, a triangular rubber core 2, and a steel wire ring 3. The composite sidewall 8 is located on the outside of the tire body 1 and includes: an upper sidewall rubber 6, a lower sidewall rubber 7, a wear-resistant rubber 4, and a reinforcing layer 5. The lower sidewall rubber 7 is laid inside the upper sidewall rubber 6. The upper sidewall rubber 6 and the lower sidewall rubber 7 are different colors. The wear-resistant rubber 4 extends sequentially from the lower end of the upper sidewall rubber 6. The reinforcing layer 5 is laid inside the lower sidewall rubber. A transition layer is laid inside the reinforcing layer 5. The reinforcing layer 5 extends downward to the wear-resistant rubber 4 and is a double-layer integrated structure. The triangular rubber core 2 and the steel wire ring 3 are located on the inner side between the two layers. The triangular rubber core 2 is connected to the upper end of the steel wire ring 3.

[0021] In a specific embodiment of this application, the upper tire sidewall rubber 6 material comprises rubber, pigment, and anti-wear agent, wherein the pigment is black; the lower tire sidewall rubber 7 material comprises rubber, pigment, and anti-wear agent, wherein the pigment is red; the thickness of the wear-resistant rubber 4 is the sum of the thickness of the upper tire sidewall rubber 6 and the lower tire sidewall rubber 7; the reinforcing layer 5 is also sprayed with reflective paint; the rubber material of the reinforcing layer 5 is yellow or purple; the color of the lower tire sidewall rubber 710 and the rubber material of the reinforcing layer 513 are not limited, but should be distinguishable from black; each layer of rubber material is different.

[0022] The upper tire sidewall 6 and lower tire sidewall 7 are made of the same material. This prevents the upper tire sidewall 6 and lower tire sidewall 7 from separating due to material differences after high-speed driving or prolonged use. The different colors of the upper and lower tire sidewall 6 and 7 also allow the exposed tire color to be revealed after wear on the tire's composite sidewall 8, prompting the user to replace the tire and ensuring driving safety. When the tire sidewall is damaged, the driver can determine the extent of the damage based on the color of the exposed rubber, judging whether the tire can continue to be driven. When the exposed rubber is red, the tire is moderately damaged; when the exposed rubber is yellow or purple, the tire is severely damaged. Besides providing a convenient way for consumers to visually inspect tire safety, this system helps the tire industry adopt new safety concepts and standardized tire wear warning structures. Furthermore, it prevents the use of old tires for repair and the production of second-hand tires, thus reducing the second-hand tire market and the number of second-hand tire consumers.

[0023] In a specific embodiment of this application, the thickness a of the upper sidewall rubber 6 satisfies: a > 1 mm; the thickness b of the lower sidewall rubber 7 satisfies: 1 mm ≤ b ≤ 7 mm; the thickness of the wear-resistant rubber 4 is the sum of the thicknesses of the upper sidewall rubber 6 and the lower sidewall rubber 7; the thickness c of the reinforcing layer 5 satisfies: 3 mm ≤ c ≤ 8 mm; and the hardness values ​​of the upper sidewall rubber 6, the lower sidewall rubber 7, and the reinforcing layer 5 in the composite sidewall 8 are related as follows: the hardness value of the reinforcing layer 5 > the hardness values ​​of the upper sidewall rubber 6 and the lower sidewall rubber 7.

[0024] In a specific embodiment of this application, the upper tire sidewall rubber 6 and the lower tire sidewall rubber 7 have similar properties, with tensile strength of 15-19 MPa, elongation at break of 500-700%, 300% constant elongation stress of 5-8 MPa, 100% constant elongation stress of 1.5-3 MPa, and hardness of 54-60.

[0025] When the tire is in good condition and the sidewall is not damaged by external force, the monthly air tightness loss rate of this tire is less than 3%. Through the design optimization of the thickness of the lower sidewall rubber 7, it is ensured that when the tire sidewall is damaged to the position of the lower sidewall rubber 7, the tire loss rate is less than or equal to 3%. At this time, the tire is at risk of pressure loss. The addition of the reinforcing layer 5 can minimize the risk of pressure loss. The design of the multi-composite sidewall 8 does not affect the tire's high-speed, size, strength, and bead separation tests.

[0026] In a specific embodiment of this application, the upper end of the triangular core 2 is bonded to the transition layers on the inner and outer sides, and the height of the triangular core 2 is 13-22mm.

[0027] This application embodiment, through the design of the triangular rubber core 2, increases the tire's warning function while also increasing the rigidity of the tire sidewall, thereby improving tire durability and lifespan. The height of the triangular rubber core 2 designed in this application is smaller than that of the traditional triangular rubber core 2 design, reducing tire weight and thus lowering costs. The hardness gradient changes of the bead, reinforced sidewall, and sidewall rubber ensure the appropriate rigidity of the tire sidewall, preventing the tire from becoming too soft due to the reduced size of the tire sidewall and reducing comfort performance. This sidewall structure design ensures a uniform distribution of rigidity from the rim and bead to the sidewall, thereby ensuring uniform stress distribution and improving tire durability.

[0028] Therefore, this application, through the design of the color and thickness of the sidewall rubber material, enables the tire sidewall to be easily distinguished by color with the naked eye when it is damaged by external force and the damage depth is relatively deep, thereby achieving a warning function and indicating the safety of tire use.
