Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a tire. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance, while also requiring high wear resistance, flexural strength, and low rolling resistance and heat generation.

[0003] To facilitate water drainage, most existing tires have longitudinal tread grooves. However, if the angle of the longitudinal tread grooves is too large, it will damage the rigidity of the tire tread and have an adverse effect on rolling resistance. If the angle of the tread grooves is too small, it is easy for stones to get stuck, causing tire damage.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve the problem of tires easily trapping stones while ensuring tire rigidity.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims protection for a tire in which at least two grooves are formed on the circumferential direction of the tire tread, and tread blocks are formed on both sides of the grooves. The grooves are evenly arranged along the width of the tire. Each groove includes a first groove section, a transition section and a second groove section. The first groove section and the second groove section are arranged at intervals along the length of the groove. The grooves of the first groove section and the second groove section are different in size. The first groove section and the second groove section are connected by a transition section to form a wavy groove.

[0008] By using different groove sizes in the first and second groove sections, the rigidity of the tire is ensured, and when stones get stuck in the groove, they can be quickly discharged along the transition section, protecting the bottom of the groove.

[0009] Preferably, the longitudinal section of the first slot section has a V-shaped slot cross-section configuration.

[0010] The gully in the first channel section is relatively gentler in narrowing compared to the gully in the second channel section, so even if stones get stuck, they can be discharged quickly and smoothly.

[0011] Preferably, the longitudinal section of the second groove segment includes a beveled part and a groove part, a trapezoidal groove is formed on the tire tread, the inner sidewall of the trapezoidal groove forms a beveled part, and a U-shaped groove is formed at the bottom of the trapezoidal groove to form a groove part.

[0012] The beveled section narrows more drastically than the V-shaped groove, and the U-shaped groove has a smaller opening. Therefore, even with grooves on the tire tread, tire rigidity can still be well maintained.

[0013] Preferably, the second included angle formed by the trapezoidal groove surface and the vertical line passing through the V-shaped groove opening is β, where 1°≤β≤30°.

[0014] Preferably, the bottom of the V-groove is provided with an arc-shaped chamfer.

[0015] The rounded chamfer can effectively buffer the trapezoidal groove surface, preventing excessive narrowing that could lead to stone trapping.

[0016] Preferably, the first angle formed by the V-shaped groove surface and the vertical line passing through the V-shaped groove opening is α, where 1°≤α≤30°.

[0017] The setting of both the second and first included angles ensures smooth drainage of the grooves while also maintaining the rigidity of the tire itself.

[0018] Preferably, the inner wall of the transition section is an arc-shaped surface, and the inner wall of the first groove section and the inner wall of the second groove section smoothly transition from the arc-shaped surface along the length direction to form a wavy groove.

[0019] As the transition section continuously changes, the groove surface periodically contracts and expands, eventually forming a wave-shaped groove.

[0020] Preferably, steel sheets are arranged circumferentially on the surface of the patterned block, with a steel sheet depth ≥ 1 mm and a steel sheet depth less than the groove depth.

[0021] The steel plates are mainly used to ensure tire rigidity.

[0022] Preferably, the steel sheet at the tread block on both shoulders of the tire is the first steel sheet. The first steel sheet includes a first groove and a second groove. The surface of the tread block is provided with a zigzag first groove along the circumference. The second groove is provided on the inner wall of the first groove facing the groove. The second groove is connected to the groove. The groove depth of the second groove and the first groove is shallower than the groove depth.

[0023] Preferably, the steel sheet on the tread block between the two shoulders of the tire is a second steel sheet. The second steel sheet includes a third groove and a fourth groove. The surface of the tread block is provided with a wavy third groove along the circumferential direction, and the fourth groove is uniformly arranged on both sides of the third groove along the length direction of the third groove. The fourth groove is connected to the groove, and the groove depth of the third groove and the fourth groove is shallower than the groove depth.

[0024] The shape and size of the steel plates are adapted to their location, primarily to ensure the safety performance of the tire. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] See Figure 1 and Figure 2This utility model claims protection for a tire with four grooves circumferentially formed on its tread. These four grooves are evenly arranged along the width of the tire and are designated as a first groove 1a, a second groove 1b, a third groove 1c, and a fourth groove 1d. Each groove includes a first groove opening section 10, a transition section 11, and a second groove opening section 12. The first groove opening sections 10 and 12 are spaced apart along the length of the groove, and are connected by the transition section 11 to form a wavy groove.

[0034] Alternating arrangement refers to the formation of several first groove sections 10 and several second groove sections 12 along the length of the trench. The first groove sections 10 and the second groove sections 12 are arranged evenly and sequentially, and the second groove sections 12 and the first groove sections 10 are connected by transition sections 11, ultimately forming a wavy trench.

[0035] The number of grooves can be adjusted adaptively based on the actual working conditions and tire width of the tire.

[0036] See Figure 1 , Figure 2 and Figure 3 The longitudinal section of the first groove segment 10 has a V-shaped groove cross-section. The bottom of the V-shaped groove is provided with an arc-shaped chamfer. The first angle formed by the V-shaped groove surface and the vertical line passing through the groove opening of the V-shaped groove is α, where 1°≤α≤30°.

[0037] The first included angle refers to the first reference surface formed by passing through the center of the tire and penetrating the first groove segment 10. The first groove segment 10 has a V-shaped groove cross-section on the first reference surface. The bottom of the V-shaped groove is provided with an arc chamfer. On the first reference surface, with the V-shaped groove opening as the origin and the line connecting the V-shaped groove opening and the center of the tire as the Y-axis, the first included angle formed between the V-shaped groove surface and the Y-axis is α.

[0038] See Figure 1 , Figure 2 and Figure 4 The longitudinal section of the second groove segment 12 includes an inclined surface 120 and a groove portion 121. A trapezoidal groove is opened on the tire tread. The inner sidewall of the trapezoidal groove forms an inclined surface 120. A U-shaped groove is opened at the bottom of the trapezoidal groove to form the groove portion 121. The second included angle formed by the surface of the trapezoidal groove and the vertical line passing through the groove opening of the V-shaped groove is β, where 1°≤β≤30°.

[0039] The second included angle refers to the second reference plane formed by passing through the center of the tire and penetrating the second groove segment 12. The second groove segment 12 has a trapezoidal groove cross-section on the second reference plane. A U-shaped groove is opened at the bottom of the trapezoidal groove. On the second reference plane, with the groove opening of the trapezoidal groove as the origin and the line connecting the groove opening of the trapezoidal groove and the center of the tire as the y-axis, the included angle formed between the groove surface of the trapezoidal groove and the y-axis is β.

[0040] See Figure 1 , Figure 2 and Figure 5 The inner wall of the transition section 11 is an arc-shaped surface. When transitioning from the first groove section 10 to the second groove section 12, the groove surface transitions evenly in an arc shape along the length of the groove. The middle of the inner wall of the V-shaped groove surface gradually bulges inward until the upper groove surface is flush with the trapezoidal groove surface, and the lower groove surface is flush with the U-shaped groove surface. The second included angle gradually increases until it is equal to the size of the first included angle.

[0041] The transition from the first groove segment 10 to the second groove segment 12 will not be described in detail. However, during the continuous transition of the transition segment 11, the groove surface periodically shrinks and expands, eventually forming a wave-shaped groove.

[0042] The tire tread on both sides of the groove forms five tread blocks, and grooves are arranged along the circumferential direction on the surface of the tread blocks, with a groove depth of ≥1mm.

[0043] The number of tread blocks is mainly determined by the number of grooves, but it is necessary to ensure that tread blocks are set on both shoulders of the tire to form a closed shoulder and ensure the overall strength of the tire.

[0044] See again Figure 1 and Figure 2 The tread blocks on both shoulders of the tire are a first tread block 2a and a second tread block 2b, respectively. The steel sheet set at the first tread block 2a and the second tread block 2b is a first steel sheet. The first steel sheet includes a first groove 201 and a second groove 202. The surface of the tread block is provided with a zigzag first groove 201 along the circumference. The second groove 202 is provided on the inner wall of the first groove 201 facing the groove. The second groove 202 is connected to the groove. The groove depth of the second groove 202 and the first groove 201 is shallower than the groove depth.

[0045] The first groove 201 in the zigzag shape refers to the V-shaped lobes connected end to end, forming a zigzag structure.

[0046] The tread blocks in the middle of the tire are the third tread block 2c, the fourth tread block 2d, and the fifth tread block 2e. The steel sheets set at the third tread block 2c, the fourth tread block 2d, and the fifth tread block 2e are the second steel sheets. The second steel sheets include the third groove 210 and the fourth groove 211. The surface of the tread block is provided with a wavy third groove 210 along the circumferential direction, and the fourth groove 211 is evenly provided on both sides of the third groove 210 along the length direction of the third groove 210. The fourth groove 211 is connected to the groove. The groove depth of the third groove 210 and the fourth groove 211 is shallower than the groove depth.

[0047] The working principle of this utility model is as follows:

[0048] The second groove section 12 has a small groove angle, meaning the second included angle is small, which provides greater support to the tire tread and results in relatively higher tire rigidity. In contrast, the first groove section 10 has a large groove angle, meaning the first included angle is large, which provides less support to the tire tread. When stones are trapped in the grooves, especially given the small diameter of the second groove section 12, it is even more difficult for them to be expelled. By incorporating a transition section 11, trapped stones tend to move towards the transition section 11 as the tire rotates, eventually being expelled and protecting the groove bottom. This approach ensures both tire rigidity and prevents trapped stones from damaging the groove bottom, achieving two goals at once.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
