Description

Technical Field

[0001] The utility model belongs to the field of tires, and particularly relates to a light truck tire tread pattern and a tire. Background Art

[0002] In the automotive field, tires are the only components that come into contact with the ground, and their performance is directly related to the vehicle's handling and stability. Different types of vehicles have different requirements for tires. Especially for light trucks, since they need to carry weights and adapt to various road conditions, their tire designs must possess characteristics such as wear resistance, high adhesion, and low rolling resistance.

[0003] However, in the existing light truck tire market, there are a wide variety of common tire tread patterns. However, most of these tires are improvements based on existing patterns and are not specifically designed for the special usage scenarios of light trucks. For example, existing tire designs still have deficiencies in aspects such as wear resistance, noise control, and grip. Especially when dealing with complex road conditions or extreme climate conditions, the performance of the tires is not satisfactory. These defects not only affect the vehicle's stability and handling but also may increase the vehicle's operating costs and reduce its safety. Therefore, it is particularly important to develop a tire tread pattern and tire design specifically for the usage characteristics of light trucks. Summary of the Utility Model

The length of the first shoulder transverse groove is greater than the length of the second shoulder transverse groove.

[0008] In some of these embodiments, the light truck tire tread pattern further includes a central longitudinal groove and two shoulder longitudinal grooves. The central longitudinal groove is wavy and is arranged between the two rows of tread blocks; the shoulder longitudinal groove is wavy and is arranged between the adjacent tread block and the shoulder tread block; the width of the central longitudinal groove is greater than the width of the two shoulder longitudinal grooves.

[0009] In some of these embodiments, the first shoulder transverse groove is zigzag. One end of the first shoulder transverse groove away from the tread block is open, and the other end of the first shoulder transverse groove is closed on the shoulder tread block and the other end is arc-shaped; the second shoulder transverse groove is rectangular. One end of the second shoulder transverse groove away from the tread block is open, and the other end of the second shoulder transverse groove is closed on the shoulder tread block.

[0010] In some of these embodiments, the first diagonal groove is arranged along the transverse direction of the tread. The first diagonal groove is semi-open. One end of the first diagonal groove communicates with the central longitudinal groove or the shoulder longitudinal groove, and the other end of the first diagonal groove is closed on the tread block and the other end is arc-shaped.

[0011] In some of these embodiments, on one side of the shoulder tread block close to the shoulder longitudinal groove, there is a second diagonal groove. One end of the second diagonal groove communicates with the shoulder longitudinal groove, and the other end of the second diagonal groove is closed on the shoulder tread block and the other end is arc-shaped. The widths of the second diagonal groove and the first diagonal groove are both 1.9 mm - 2.1 mm, and the depths are both 4.4 mm - 4.6 mm.

[0015] On the other hand, the present utility model also provides a light truck tire, which includes the light truck tire tread pattern described in any of the above embodiments.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model discloses a light truck tire tread pattern. The tread pattern blocks are arranged in two rows at intervals in the form of polygonal pattern blocks and are designed to be centrosymmetric. It is not only beautiful but also can reduce the rigidity of the tread pattern blocks, thereby reducing the noise during vehicle driving and increasing driving comfort. The setting of the shoulder pattern blocks and the design of the Z-shaped grooves thereon can increase the stability and lateral grip of the tire during turning. The setting of a cylinder at the two corners in the Z-shaped groove can reduce the noise penetrating the shoulder pattern blocks and at the same time reduce the force deformation of the pattern blocks, extending the service life of the tire.

[0018] 2. By designing the first shoulder transverse groove and the second shoulder transverse groove on the shoulder pattern blocks, the present utility model can not only effectively reduce the stiffness at the shoulders, but also, since most light trucks have a double-wheel position design for the rear wheels, effectively prevent stones and the like from being caught inside the two tires through the design of the first shoulder transverse groove and the second shoulder transverse groove; it can also effectively prevent the sidewall from being scratched, and the pattern blocks in the recessed part are more likely to deform compared with ordinary tires. When hitting the curb or other sharp objects, such shoulder pattern blocks can greatly reduce the probability of being damaged, thereby extending their service life; the design of multiple second shoulder transverse grooves can not only weaken the rigidity at the shoulders but also ensure the grip performance and handling stability of the vehicle during high-speed turning.

[0019] 3. By designing the central longitudinal groove and the shoulder longitudinal groove and adopting a water flow design, the present utility model can effectively ensure the best straight-line driving stability. The wavy design of the central longitudinal groove and the setting of the two shoulder longitudinal grooves not only enhance the drainage capacity of the tire but also further improve the stability and handling performance of the tire during straight-line driving.

[0020] 4. The utility model designs the first shoulder transverse groove and the second shoulder transverse groove to be open at one end and closed at the other end, which can ensure that the tire has sufficient grounding area while having a strong function of draining water, mud, small particles such as gravel, etc.

[0021] 5. The utility model adopts a semi-open design for the first diagonal groove. The open end can quickly drain water, prevent the formation of a water film, and improve the wet grip of the tire. The arc-shaped design of the closed end helps to reduce the risk of cracks in the tread pattern blocks and extend the service life of the tire.

[0022] 6. In the utility model, the position of the second diagonal groove close to the shoulder longitudinal groove and its same size design as the first diagonal groove enable it to further enhance the drainage performance of the tire and provide consistent grip on dry and wet roads.

[0023] 7. In the utility model, further optimizing the width of the Z-shaped groove and the size of the cylinder can further improve the flexibility and anti-deformation ability of the shoulder, increase the stability of the tire during high-speed driving, reduce the wear of the shoulder part at the same time, and extend the service life of the tire.

[0024] 8. In the utility model, by designing the first shoulder transverse groove and the second shoulder transverse groove with different widths and depths, the drainage performance and wear resistance of the tire are enhanced respectively.

[0025] 9. In the utility model, by designing the width and depth of the central longitudinal groove and the shoulder longitudinal groove, the drainage channel of the tire is optimized, the drainage efficiency is improved, and further the anti-skid performance and driving stability of the tire on wet roads are enhanced.

[0026] 10. The overall design of the pattern in the utility model enables the light truck tire to provide excellent grip, wear resistance, drainage performance and noise control performance under various road conditions, and improves the handling stability, stability and safety of the vehicle.

Detailed implementation manners

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described and explained below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Based on the embodiments provided by the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0031] An embodiment of the present utility model provides a light truck tire tread pattern. Figure 1 It is a structural schematic diagram of a light truck tire tread pattern according to an embodiment of the present utility model. Refer to Figure 1 As shown, the light truck tire tread pattern at least includes a tread pattern block 1 and a shoulder pattern block 2. The tread pattern block 1 is polygonal and arranged in two rows at intervals. The two rows of tread pattern blocks 1 are centrosymmetric and parallel, and the tread pattern blocks 1 are distributed circumferentially along the tread. Each tread pattern block 1 is alternately provided with a first diagonal groove 101; the shoulder pattern block 2 is arranged on both the inner and outer sides of the tread and is distributed circumferentially along the tread. The shoulder pattern block 2 is provided with a Z-shaped groove 201; the Z-shaped groove 201 extends circumferentially along the tread from one side of the shoulder pattern block 2 and passes through the shoulder pattern block 2 until the other side of the shoulder pattern block 2; a cylinder 202 is provided at each of the two corners in the Z-shaped groove 201. The tread pattern block 1 is a polygonal pattern block arranged in two rows at intervals and is centrosymmetrically designed, which is not only beautiful but also can reduce the rigidity of the tread pattern block 1, thereby reducing the noise during vehicle driving and increasing driving comfort. The setting of the shoulder pattern block 2 and the design of the Z-shaped groove 201 thereon can increase the stability and lateral grip of the tire during turning. Setting a cylinder 202 at each of the two corners in the Z-shaped groove 201 can reduce the noise penetrating the shoulder pattern block 2 and at the same time reduce the force deformation of the pattern block, extending the service life of the tire.

[0032] Further, on one side of the shoulder tread block 2 away from the tread block 1, first shoulder transverse grooves 203 are arranged alternately along the circumferential direction of the tread. Between two adjacent first shoulder transverse grooves 203, a plurality of second shoulder transverse grooves 204 are arranged side by side. The length of the first shoulder transverse groove 203 is greater than that of the second shoulder transverse groove 204. By designing the first shoulder transverse groove 203 and the second shoulder transverse groove 204 on the shoulder tread block 2, not only can the stiffness at the shoulder be effectively reduced, but also since the rear wheels of most light trucks are designed with dual wheel positions, stones and the like can be effectively prevented from being caught between the two tires through the design of the first shoulder transverse groove 203 and the second shoulder transverse groove 204; it can also effectively prevent the sidewall from being scratched, and the tread blocks in the concave part are more likely to deform compared with ordinary tires. When hitting a curb or other sharp objects, this kind of shoulder tread block 2 can greatly reduce the probability of being damaged, thereby extending its service life; the design of a plurality of second shoulder transverse grooves 204 can not only weaken the rigidity at the shoulder, but also ensure the grip performance and handling stability of the vehicle when turning at high speed.

[0033] In some embodiments, the number of the second shoulder transverse grooves 204 is three. This design can not only weaken the rigidity at the shoulder, but also ensure the grip performance and handling stability of the vehicle when turning at high speed.

[0034] Further, the light truck tire tread also includes a central longitudinal groove 3 and two shoulder longitudinal grooves 4. The central longitudinal groove 3 is wavy and is arranged between two rows of tread blocks 1. The two shoulder longitudinal grooves 4 are also wavy and are arranged between adjacent tread blocks 1 and shoulder tread blocks 2. The width of the central longitudinal groove 3 is greater than that of the two shoulder longitudinal grooves 4. The wavy design of the central longitudinal groove 3 and the shoulder longitudinal grooves 4 improves the self-cleaning ability of the tire by guiding water flow and mud to drain along the grooves. The larger width of the central longitudinal groove 3 helps to maintain stability during straight driving, while the smaller width of the shoulder longitudinal groove 4 ensures the grip and control during turning.

[0035] Further, the first shoulder transverse groove 203 is zigzag, with one end away from the tread block 1 open and the other end closed on the shoulder tread block 2, and the other end is arc-shaped. The second shoulder transverse groove 204 is rectangular, with one end away from the tread block 1 open and the other end closed on the shoulder tread block 2. Designing the first shoulder transverse groove 203 and the second shoulder transverse groove 204 to be open at one end and closed at the other end has the function of effectively draining water, mud, small particles such as small stones while ensuring that the tire has sufficient contact area with the ground.

[0036] Furthermore, the first diagonal groove 101 is arranged transversely to the tread. The first diagonal groove 101 is semi-open, with one end communicating with the central longitudinal groove 3 or the shoulder longitudinal groove 4, and the other end being closed on the tread block 1, and its closed end is arc-shaped. The semi-open design of the first diagonal groove 101 helps to quickly drain water and mud, reduce the water film between the tire and the ground, and enhance the grip. The arc-shaped design of the closed end reduces stress concentration and improves the durability of the tread block 1.

[0037] Furthermore, a second diagonal groove 205 is provided on one side of the shoulder tread block 2 close to the shoulder longitudinal groove 4. One end of the second diagonal groove 205 communicates with the shoulder longitudinal groove 4, and the other end is closed on the shoulder tread block 2, and the closed end is arc-shaped. The widths of both the first diagonal groove 101 and the second diagonal groove 205 are 1.9 mm to 2.1 mm, and the depths are both 4.4 mm to 4.6 mm. The communication between the second diagonal groove 205 and the shoulder longitudinal groove 4 further improves the drainage capacity of the shoulder. The design with the same width and depth as the first diagonal groove 101 ensures the balanced performance of the tread block 1 and the shoulder tread block 2 and avoids excessive wear.

[0038] Furthermore, the width of the Z-shaped groove 201 is 2.2 mm to 2.5 mm, the depth is 4.2 mm to 4.4 mm, the diameter of the cylinder 202 is 2 mm to 2.2 mm, and the height is 4.2 mm to 4.4 mm. The design of the width and depth of the Z-shaped groove 201 can ensure effective drainage under various road surface conditions, further improve the flexibility and anti-deformation ability of the shoulder, increase the stability of the tire during high-speed driving, reduce the wear of the shoulder part at the same time, and extend the service life of the tire.

[0039] Furthermore, the width of the first shoulder transverse groove 203 is 4 mm to 4.2 mm, the depth is 4.8 mm to 5.0 mm, the width of the second shoulder transverse groove 204 is 1 mm to 2 mm, and the depth is 2 mm to 2.2 mm. The design of the larger width and depth of the first shoulder transverse groove 203 enables it to effectively disperse pressure when the tire is under greater stress, increasing the grip and stability of the tire. The smaller width and depth of the second shoulder transverse groove 204 can improve the overall strength of the shoulder and reduce the deformation of the tire under high pressure.

[0040] Furthermore, the width of the central longitudinal groove 3 is 10.4 mm to 10.6 mm, and the depth is 8.8 mm to 9.0 mm. The width of the shoulder longitudinal groove 4 is 9.6 mm to 9.8 mm, and the depth is 8.5 mm to 8.8 mm. The larger width design of the central longitudinal groove 3 provides good drainage and stability. Especially under wet road surface conditions, it can effectively reduce the formation of water film and maintain the tire's grip. The smaller width of the shoulder longitudinal groove 4 helps to maintain the structural strength and grip ability of the tire shoulder during turning, prevent tire skidding, and improve the anti-slip performance and driving stability of the tire.

[0041] The present utility model also provides a light truck tire, which can perform excellently under various road surface conditions, providing excellent grip, stability and durability. The combination of these tread patterns further enhances the drainage and anti-slip properties of the tire, making it have better handling performance in wet and complex road environments.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
