[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] In one embodiment, Figure 1-Figure 4As shown, a high-strength passenger car tire includes a tire body 1 and tread pattern side grooves 5. A carcass 4 is provided inside the tire body 1. The surface edge of the tire body 1 is provided with a tread pattern side groove 5 with an asymmetric pattern design, which is conducive to stone removal and avoids damage to the groove bottom, thereby improving the strength of the tire body 1. The bottom of the carcass 4 is directly wrapped on the steel wire ring 11 through a soft triangular rubber core 8, which can improve the bearing capacity of the ring and improve the tire strength.
[0026] In one embodiment, Figure 1 As shown, the bottom of the tire body 1 is adhered with a belt layer 2 through a cushion rubber 3 to mitigate impact.
[0027] In one embodiment, Figure 1 As shown, the outer surface of the tire body 4 is evenly coated with sidewall soft rubber 6 to reduce the weight of the tire and reduce fuel consumption.
[0028] In one embodiment, Figure 1 As shown, the bottom of the carcass 4 and the turned-up end point of the wire wrap 10 are provided with a sub-mouth reinforcing rubber 7 for protecting the bottom of the carcass 4 and the turned-up end point of the wire wrap 10 so that the durability of the tire is not affected.
[0029] In one embodiment, Figure 1 As shown, one side of the carcass 4 is connected to the wire cloth 10 through a molded rubber 9.
[0030] In one embodiment, Figure 4 As shown, the design range of the first groove bottom slope angle 15 of the tread pattern side groove 5 is 3-6°, so as to avoid the design value being too low, the stone removal effect is not obvious, or the design value being too high, which will cause stress concentration at the groove bottom and cause early damage problems. The first groove bottom slope angle 15 and the second groove bottom slope angle 16 are inconsistent, and an asymmetric design is adopted, which is conducive to stone removal and avoids damage to the groove bottom, thereby improving the strength of the tire body 1.
[0031] In one embodiment, Figure 3 As shown, a tread block 13 is fixedly connected to the surface of the tire body 1, and a plurality of tread block sipes 14 are provided on the surface of the tread block 13. The tread block sipes 14 are evenly arranged at a distance of 40 mm in length on the tread block 13, and steel sheets are arranged inside the tread block sipes 14, thereby improving the longitudinal stiffness of the tread block 13, making its surface grip performance better, and improving the tire's anti-skid ability.
[0032] In one embodiment, Figure 2 As shown, a plurality of groups of water injection holes 12 are evenly arranged on the surface of the tread pattern block 13 , and the water injection holes 12 can improve the anti-slip ability of the tire body 1 .
[0033] Working principle: The above embodiment discloses a high-strength passenger car tire, wherein, when in use, the tread pattern side groove 5 with an asymmetric pattern design is conducive to stone removal and avoids damage to the groove bottom, thereby improving the strength of the tire body 1. The bottom of the tire body 4 is directly wrapped on the steel wire ring 11 through the soft triangular rubber core 8, which can improve the bearing capacity of the ring part and improve the strength of the tire. By arranging steel sheets inside the tread block grooves 14, the longitudinal stiffness of the tread block 13 is increased, the surface grip performance is better, and the tire's anti-skid ability can be improved.
[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
