[0002] As a key component supporting the entire vehicle, a car's driving tires must support the vehicle's weight and evenly distribute the load to the ground, ensuring smooth driving. The friction between the driving tires and the ground is crucial for ensuring stable driving and acceleration. Furthermore, the driving tires are part of the vehicle's powertrain, responsible for transmitting power generated by the engine or electric motor to the ground. Combined with the friction between the tires and the ground, they propel the car forward and backward.

[0003] In recent years, with market development, commercial vehicle owners have increasingly demanded tires with low rolling resistance, high mileage, and low noise performance. However, existing drive tires on the market generally suffer from poor wear resistance, low mileage, and poor fuel efficiency. Tire tread design directly impacts tire performance, and treads can be optimized based on the specific application and driving environment to achieve the desired performance. Current products no longer meet current customer demands for energy-saving and high mileage tires. The market urgently needs a drive tire tread with high wear resistance, high mileage, and low rolling resistance. Utility Model Content

[0004] The purpose of the present utility model is to solve the above-mentioned problems existing in the prior art, and proposes a driving tire pattern and tire. The pattern design provides the vehicle with a faster driving and braking response, while improving grip, ensuring stable starting and braking performance, bringing reliable safety protection to car owners, playing a more positive role in mileage, service life and safety, and meeting the new needs of more car owners.

[0005] The technical solution of the utility model is:

[0006] This utility model focuses on high wear resistance, low heat generation, low rolling resistance and other properties. It uses special FEA tire simulation technology to simulate the stress and ground contact conditions of the tire under different loads. Based on the simulation results, it continuously optimizes and improves to determine the optimal pattern design scheme.

[0007] A driving tire pattern comprises a first longitudinal groove located in the middle of the tread, and second longitudinal grooves and side grooves sequentially arranged on both sides of the first longitudinal groove; an intermediate pattern block is arranged between the first longitudinal groove and the second longitudinal groove, and the two intermediate pattern blocks are staggered and symmetrically distributed; a rib pattern block is arranged between the second longitudinal groove and the side groove, and the two rib pattern blocks are staggered and symmetrically distributed;

[0008] It also includes shoulder pattern blocks arranged on the shoulders of the tire on both sides, and reinforcing ribs are arranged between the shoulder pattern blocks distributed at equal intervals in the longitudinal direction; the width of the shoulder pattern blocks is 1.40 to 1.50 times the width of the middle pattern blocks, and the width of the rib pattern blocks is 0.95 to 1.05 times the width of the middle pattern blocks; S-shaped grooves are arranged transversely on the shoulder pattern blocks, and transverse steel sheets distributed at equal intervals are arranged on the middle pattern blocks and the rib pattern blocks, and the transverse steel sheets are equal-depth broken lines with an angle of 60° to 70°.

[0009] Furthermore, the width of the transverse steel sheet is 0.5-1 mm, the transverse projection length is 29.5-30.5 mm, and the depth is 70%-80% of the depth of the middle groove.

[0010] Furthermore, the first longitudinal groove is a V-shaped groove with a width of 3.5 to 4.5 mm, a groove wall angle β2 of 2.5° to 3.5°, and a groove bottom designed in a full arc shape.

[0011] Furthermore, the angle α1 of the second longitudinal groove is 5° to 7°, the second longitudinal groove is a V-shaped groove with a width of 2 to 3 mm, the groove wall angle β3 is 1° to 2°, and the groove bottom adopts a full arc design.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be noted that the terms "middle", "both sides", "upper", "lower", etc., indicating orientations or positional relationships, are based on the positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0028] like Figure 1 As shown, the utility model relates to a driving tire pattern, including a first longitudinal groove 1 located in the middle of the tread, and a second longitudinal groove 2 and an edge pattern groove 3 sequentially arranged on both sides of the first longitudinal groove 1. A five-groove staggered symmetrical design is adopted, and the optimal pattern block proportion distribution is selected through finite element simulation.

[0029] An intermediate pattern block 4 is provided between the first longitudinal groove 1 and the second longitudinal groove 2, with the two intermediate pattern blocks 4 arranged in a staggered, symmetrical pattern on either side of the tread centerline. A rib pattern block 5 is provided between the second longitudinal groove 2 and the edge groove 3, with the two rib pattern blocks 5 arranged in a staggered, symmetrical pattern on either side of the tread centerline. This staggered, symmetrical pattern design reduces pattern deformation during driving, improves pattern block rigidity, contributes to the tire's fuel efficiency, and reduces noise.

[0030] The tire pattern also includes shoulder blocks 6 located on both shoulders. In this specific embodiment, the width of the shoulder blocks 6 is 1.40 or 1.50 times the width of the center blocks 4, while the width of the rib blocks 5 is 1 times the width of the center blocks 4. This design provides the tire with a more optimized contact patch, ensuring more even distribution of contact pressure, reducing uneven wear in the early stages of tire development, and significantly improving tire wear performance. The rational distribution of blocks optimizes pattern rigidity, reduces the tire's rolling resistance coefficient, and improves fuel efficiency.

[0031] To improve tire fuel efficiency and wear resistance, the tire tread blocks of this embodiment utilize thin steel blades. Specifically, evenly spaced transverse steel blades 8 are provided on the center tread blocks 4, and evenly spaced transverse steel blades 8 are provided on the rib tread blocks 5. The transverse steel blades 8 utilize a 70° angle α3 with constant depth broken lines. This effectively enhances tread block rigidity, reduces deformation during driving, and thus reduces the tire's rolling resistance coefficient, improving fuel efficiency. Furthermore, a tread saturation of 75% or 80% improves tire wear resistance. Furthermore, the transverse steel blades 8 have a projected length of 30 mm, a width of 0.8 mm, and a depth of 70% or 80% of the center tread groove depth. This transverse steel blade design effectively improves tire heat dissipation while also enhancing driving, braking, and wet-slip performance. Finite element simulations have shown that this optimal steel blade design can effectively enhance tread rigidity, reduce rolling resistance, and enhance fuel efficiency while maintaining driving performance.

[0032] like Figure 2 As shown, the side groove 3 of the driving tire pattern adopts a funnel-shaped design, with a width gradually varying from 8.5 to 9.5 mm from top to bottom, and a groove wall angle β1 of 10°. Figure 3 As shown, the first longitudinal groove 1 adopts a V-shaped groove design with a width gradually changing from 3.5 to 4.5 mm, and its groove wall angle β2 is 3.0°. Figure 4As shown, the second longitudinal groove 2 has an angle α1 of 6°. The second longitudinal groove 2 is a V-shaped groove with a width gradually varying from 2 to 3 mm, and its groove wall angle β3 is 2°. The bottoms of all these longitudinal grooves are fully arc-shaped, reducing stress concentration areas at the bottom and effectively preventing cracking caused by deformation of the groove bottom. This groove design effectively improves heat dissipation in the crown area, allowing heat to be dissipated promptly during driving, reducing early damage to the crown caused by tread heat generation. Furthermore, the longitudinal grooves ensure excellent drainage and handling performance.

[0033] from Figure 1 As can be seen above, the shoulder blocks 6 are transversely provided with S-shaped grooves 7, and reinforcing ribs 9 are placed in the transverse grooves between the shoulder blocks 6 at equal intervals. The width of the reinforcing ribs 9 is 60% or 65% of the width of the shoulder blocks 6, and their height is 60% or 65% of the depth of the transverse groove between two shoulder blocks 6. This design of the shoulder reinforcing ribs 9 can reduce deformation between the shoulder blocks 6, effectively reduce shoulder heat generation, and prevent shoulder void problems in the early stages of tire use. Proper design of the reinforcing ribs 9 can also prevent cracking in the shoulder transverse grooves during tire use.

[0034] Furthermore, the shoulder section features an open shoulder design, with the shoulder block 6 angle α2 set at 70° or 80°. This design effectively reduces shoulder heat generation during driving, minimizing shoulder voids caused by heat accumulation in the shoulder section. A 4mm chamfer is applied to the lateral edges of the shoulder blocks 6 to eliminate sharp corners, effectively preventing damage such as block dropout and dents during use.

[0035] In addition, shoulder petals 10 are provided on the shoulders on both sides. The shoulder petals 10 are 9mm wide, 30mm long and 3mm high. The larger shoulder petals 10 combined with the shoulder open design can effectively reduce the heat accumulation in the shoulders, avoid the shoulder void problem in the early use of the tire, and can reduce the weight of the tire and improve the economy of the tire.

[0036] This embodiment also provides a driving tire having the above tire pattern structure.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and modifications made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
