Description

Technical Field

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

[0002] The development of all-steel desert tires is primarily driven by the specific performance requirements of harsh terrains such as deserts. In desert environments, tires need to withstand multiple challenges, including high temperatures, sand and gravel impacts, and low coefficients of friction. Therefore, all-steel desert tires are typically designed with deeper treads, more durable materials, and special tire carcass structures to improve stability and traction in desert conditions.

[0003] With the rise of off-road adventures and desert tourism, the market demand for all-steel desert tires is gradually increasing. At the same time, tire manufacturers are constantly exploring the application of new technologies and materials to improve the performance and durability of all-steel desert tires. Currently, several high-performance all-steel desert tire products have appeared on the market, demonstrating excellent stability and grip in desert environments.

[0004] Despite significant performance improvements, all-steel desert tires still have some problems and drawbacks: 1. Limited heat resistance: Although all-steel desert tires prioritize heat resistance in their material selection, the internal temperature and air pressure of the tire may still rise rapidly under extreme high-temperature conditions, increasing the risk of tire blowout. 2. Inconsistent grip performance: The grip of all-steel desert tires is affected by a variety of factors, such as tire tread design and material hardness. In some desert terrains, the grip of all-steel desert tires may not be as good as that of specially designed sand tires or off-road tires. 3. Weight and fuel consumption: All-steel desert tires typically use stronger materials and more complex tire structures, resulting in increased tire weight. This not only increases the vehicle's fuel consumption but may also affect the vehicle's handling performance. 4. Maintenance costs: The maintenance costs of all-steel desert tires are relatively high. Due to the special tire materials and complex structure, once damaged, repairs are difficult and expensive.

[0005] In conclusion, all-steel desert tires have significant advantages in harsh terrain, but continuous improvement and optimization are still needed in terms of heat resistance, grip, weight, fuel consumption, and maintenance costs. Utility Model Content

[0007] This invention proposes a desert tire that solves the technical problem of poor grip of existing desert tires and has the characteristic of good grip.

[0008] This utility model discloses a desert tire, including side tread ribs extending circumferentially along the tire tread and disposed near the tire shoulder, the side tread ribs including: The first side pattern block includes rectangular or square pattern blocks and parallelogram pattern blocks, with one side of the rectangular or square pattern block coinciding with one side of the parallelogram pattern block. The second side tread block is alternately arranged with the first side tread block along the circumferential direction of the tire tread; it is formed by arranging two first side tread blocks along the circumferential direction of the tire tread, and the two first side tread blocks of the same second side tread block overlap along the radial side of the tire tread.

[0009] In some embodiments, the first side patterned block includes a first steel groove, which is provided along the overlapping side of the rectangular or square patterned block and the parallelogram pattern. The second side patterned block includes a second steel blade groove, which is provided along the overlapping edge of the two first side patterned blocks of the same second side patterned block.

[0010] In some embodiments, the desert tire includes a central tread rib extending circumferentially along the centerline of the tire tread.

[0012] In some embodiments, the desert tire also includes an intermediate tread rib located between the side tread ribs and the central tread rib; longitudinal tread grooves extending continuously along the circumference of the tire tread are provided between the side tread ribs and the intermediate tread ribs, and between the intermediate tread ribs and the central tread ribs.

[0013] In some embodiments, the intermediate patterned ribs include: First central pattern block; The second intermediate tread block is alternately arranged with the first intermediate tread block along the circumferential direction of the tire tread; it is formed by arranging two first intermediate tread blocks along the circumferential direction of the tire tread, and the two first intermediate tread blocks of the same second intermediate tread block overlap along the radial side of the tire tread.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0021] This utility model embodiment provides a desert tire. Figure 1 This is a structural schematic diagram of a desert tire according to an embodiment of the present invention.

[0022] refer to Figure 1 As shown, the desert tire includes side tread ribs extending circumferentially along the tire tread and located near the tire shoulder. The side tread ribs include a first side tread block 101 and a second side tread block 102. The second side tread block 102 is alternately arranged with the first side tread block 101 along the tire tread circumferentially. The first side tread block 101 includes rectangular or square tread blocks and parallelogram tread blocks, with one side of the rectangular or square tread block coinciding with one side of the parallelogram tread block. The second side tread block 102 is formed by arranging two first side tread blocks 101 along the tire tread circumferentially, and the two first side tread blocks 101 of the same second side tread block 102 coincide along the radial side of the tire tread.

[0023] The aforementioned desert tire, through its structure defining the side tread ribs, alternates between irregularly shaped first and second side tread blocks 101 and 102, increasing the contact area between the tread blocks and the ground. This provides more engagement points when the tire contacts the ground, allowing these tread blocks to better "fit" with the ground during acceleration, braking, or cornering, enhancing friction and thus improving grip. Simultaneously, by defining the relationship between the second side tread block 102 and the first side tread block 101, it helps ensure the aesthetics and visual uniformity of the tread pattern, while reducing the difficulty and complexity of mold processing, thereby improving production efficiency. Furthermore, the large tread block design of the second side tread block 102 helps ensure heat dissipation of the large tread area and effectively prevents chipping.

[0024] In some embodiments, the desert tire includes a central tread rib extending circumferentially along the centerline of the tire tread. The central tread rib includes a plurality of central tread blocks 2, which are arranged circumferentially along the centerline of the tire tread and spaced apart.

[0025] The repeating tread pattern in the center typically creates continuous and regular drainage and mud / sand grooves. These grooves quickly expel water and sand from between the tire and the ground, preventing the formation of a water film that drastically reduces tire-to-ground friction and thus avoiding hydroplaning, improving vehicle safety and handling. The regular, repeating tread blocks ensure a more even contact area between the tire and the ground. During driving, each tread block makes full contact with the ground, providing stable grip and better vehicle stability during acceleration, braking, and cornering. The repeating tread structure also contributes to more even tire wear. Because the stress on each tread block is relatively uniform, there is no localized excessive wear. Even wear allows the tire to maintain relatively stable performance throughout its lifespan, extending tire life, reducing the frequency of tire replacement, and saving on operating costs.

[0026] In some embodiments, the desert tire also includes an intermediate tread rib located between the side tread ribs and the central tread rib; longitudinal tread grooves 6 extending continuously along the circumference of the tire tread are provided between the side tread ribs and the intermediate tread ribs, and between the intermediate tread ribs and the central tread ribs.

[0027] In some embodiments, the intermediate tread rib includes a first intermediate tread block 301 and a second intermediate tread block 302; the second intermediate tread block 302 is alternately spaced with the first intermediate tread block 301 along the circumferential direction of the tire tread; it is formed by arranging and combining two first intermediate tread blocks 301 along the circumferential direction of the tire tread, and the two first intermediate tread blocks 301 of the same second intermediate tread block 302 overlap along the radial side of the tire tread.

[0028] By defining the relationship between the second intermediate pattern block 302 and the first intermediate pattern block 301, it is beneficial to ensure the aesthetics and overall visual uniformity of the pattern, while also reducing the difficulty and complexity of mold processing and improving production efficiency. Furthermore, the large pattern block design of the second intermediate pattern block 302 helps ensure heat dissipation of the large pattern and effectively avoids the problem of pattern chipping.

[0029] In some embodiments, the intermediate tread ribs further include reinforcing ribs 7 that connect adjacent first intermediate tread blocks 301 and second intermediate tread blocks 302; the reinforcing ribs 7 have a first end and a second end located below the first end in the circumferential direction of the tire tread.

[0030] In some embodiments, the first end of the reinforcing rib 7 of the middle patterned rib located to the left of the central patterned rib is connected to the second middle patterned block 302, and the second end is connected to the first middle patterned block 301; the first end of the reinforcing rib 7 of the middle patterned rib located to the right of the central patterned rib is connected to the first middle patterned block 301, and the second end is connected to the second middle patterned block 302. The arrangement of the reinforcing rib 7 is beneficial to strengthening the connection between the blocks and effectively avoiding the problem of chipping.

[0031] In some embodiments, a first side tread block 101, a first intermediate tread block 301, a central tread block 2, a second intermediate tread block 302, and a second side tread block 102 are arranged sequentially from left to right along the same tire tread radial direction.

[0032] The aforementioned desert tires employ a multi-pattern combination: the tread blocks are not independent but arranged in a combination. These different tread blocks work together to function under stress. For example, when the vehicle turns, tread blocks in different positions deform to varying degrees according to the direction of the force. This deformation allows the tread blocks to better conform to the ground, distributing stress, further improving grip, and ensuring vehicle stability during cornering.

[0033] The aforementioned desert tire's tread grooves include lateral grooves 5 and longitudinal grooves 6. The lateral grooves effectively cut through the water film when the tire rolls. During driving, water and sand form a water film between the tire and the ground, reducing friction and making it easy to slip. The lateral grooves 5 can quickly guide the water to the sides to drain away, reducing the impact of the water film and allowing the tire to make better contact with the ground, thereby improving grip. The longitudinal grooves 6 help guide the water to drain away along the direction of tire rolling, working together with the lateral grooves 5 to form an efficient drainage network. At the same time, the longitudinal grooves 6 also play a role when driving on dry ground. They can increase the elasticity of the tread blocks, allowing them to better adapt to the undulations of the ground when subjected to force, thereby improving grip.

[0034] The aforementioned desert tires employ both staggered and symmetrical tread patterns. Staggered arrangement: The tread blocks are arranged in an alternating pattern. This arrangement prevents the tire from vibrating at a single frequency during rolling, reducing noise and ensuring more even contact between the tire and the ground. Even contact ensures that each tread block functions effectively, improving overall grip. Symmetrical arrangement: The symmetrical arrangement of the tread blocks helps ensure even force distribution during driving, preventing uneven wear. Even wear allows the tire to maintain good grip performance and extends its lifespan.

[0035] In some embodiments, the first side pattern block 101 includes a first steel groove 401, which is provided along the overlapping side of the rectangular or square pattern block and the parallelogram pattern; the second side pattern block 102 includes a second steel groove 402, which is provided along the overlapping side of the two first side pattern blocks 101 of the same second side pattern block 102.

[0036] In some embodiments, the central patterned block 2 further includes a third steel groove 403, which includes a middle portion and ends connected to the two ends of the middle portion and extending in opposite directions.

[0037] In some embodiments, the first intermediate tread block 301 includes a fourth steel sipe 404, which extends circumferentially along the tire tread and is disposed in the middle of the first intermediate tread block 301; the second intermediate tread block 302 includes a fifth steel sipe 405, which extends radially along the tire tread and is disposed in the middle of the second intermediate tread block 302.

[0038] In some embodiments, the depth of the first steel blade groove 401, the second steel blade groove 402, the third steel blade groove 403, the fourth steel blade groove 404, and the fifth steel blade groove 405 is ≤3mm, which is beneficial to the stability of the tire during driving and reduces the lateral deviation accident rate.

[0039] The patterned blocks are cut crosswise by steel sipes to form multiple smaller units, as shown below: Enhanced grip: The multi-segment design allows for flexible changes in the pattern block shape, and the small units can easily embed into minor potholes in the road surface, increasing the actual contact area; at the same time, the cross grooves refine the drainage path, accelerate the discharge of accumulated water and sand, and improve handling stability. Quiet and cushioning: When the small unit tread blocks roll, the impact and friction frequencies are dispersed, reducing tire noise through the "silencing" structure; and the large deformation space can cushion road bumps and optimize driving comfort.

[0040] The steel blade groove is folded back and irregularly shaped (third steel blade groove 403), and its setting direction is adjusted according to the pattern block layout. Technical effect: Multi-directional grip optimization: The folding grooves provide more "engagement points" on the edges of the tread blocks. When subjected to longitudinal (acceleration, braking) and lateral (turning) forces, different groove edges can "hook" with the ground, enhancing grip under various working conditions and improving handling limits (such as high-speed cornering and emergency braking). Stone removal and self-cleaning: The tortuous path of the irregular groove can "enclose" embedded small stones. During driving, the stones are thrown out by the deformation of the tread blocks and centrifugal force, reducing tire noise, preventing the tread from being damaged by stones, and maintaining stable performance.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
