Abstract
Description
Technical Field
[0001] This invention belongs to the field of tire tread pattern design technology, specifically an off-road tire applicable to all road conditions. Background Technology
[0002] As a core component for vehicles to adapt to unpaved roads, off-road tires are widely used in various off-road vehicles. They can provide grip, traction and braking support for vehicles in complex road conditions such as mountains, mud, and gravel. Especially in North America, due to the large differences in climate throughout the four seasons, the snow and ice cover in winter, and the diverse road conditions, there is a higher demand for the all-terrain adaptability of off-road tires.
[0003] However, the aforementioned traditional off-road tires still have the following problems. In terms of grip and anti-skid performance, most of them adopt a rough, wide and deep groove and a single tread block design, lacking a targeted structural combination. In icy, snowy, and slippery road conditions, they cannot effectively break through the water film and cut through the ice and snow layer. The friction between the tire and the ground is greatly reduced, making it easy to slip and deviate, resulting in poor handling stability. In addition, the traditional tread structure does not have a special design to prevent mud and stone from sticking. Mud can easily adhere to the tread blocks and grooves, and gravel can easily get stuck at the bottom of the grooves. This not only affects the effective grip of the tire, but also easily causes tread deformation and damage, increasing the risk of tire failure. At the same time, the traditional tread block arrangement will also lead to uneven stress on the tread, further reducing the durability and safety of all-terrain driving, making it difficult to adapt to the complex and ever-changing driving needs of North America. Summary of the Invention
[0004] The purpose of this invention is to provide an off-road tire applicable to all road conditions, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an off-road tire applicable to all road conditions, comprising a tire body, wherein the outer surface of the tire body is provided with shoulder tread blocks, edge tread blocks and center tread blocks, wherein the shoulder tread blocks include a first tread block and a second tread block, the first tread block and the second tread block are arranged alternately in the circumferential direction of the tire body, the edge tread blocks include a third tread block and a fourth tread block, and the number of shoulder tread blocks and edge tread blocks is multiple, wherein a center tread block is provided at the center of the edge tread blocks.
[0006] As a preferred embodiment of the present invention, the No. 3 and No. 4 tread blocks are arranged alternately in the circumferential direction of the tire body, and each shoulder tread block corresponds to each edge tread block.
[0007] As a preferred embodiment of the present invention, the two sets of shoulder tread blocks are arranged in the lateral direction of the tire body, and the two sets of edge tread blocks are staggered in the circumferential direction of the tire body.
[0008] As a preferred embodiment of the present invention, each set of two groups of edge patterned blocks forms a collection, and the edge patterned blocks of each two collections enclose and form a circular groove.
[0009] In a preferred embodiment of the present invention, the central patterned block is disposed at the center of the circulation groove, and the central patterned block and the corresponding two sets of edge patterned blocks are combined to form a spiral blade-shaped pattern structure.
[0010] As a preferred embodiment of the present invention, the central tread block is set at a preset angle to the lateral direction of the tire, and the number of the central tread blocks is multiple.
[0011] As a preferred embodiment of the present invention, the edge portions of the first pattern block, the second pattern block, the third pattern block, the fourth pattern block and the central pattern block are all provided with stepped pattern block edge structures, forming a height difference between adjacent edge structures.
[0012] As a preferred embodiment of the present invention, the stepped patterned block edge structure includes edge structure No. 1, edge structure No. 2, edge structure No. 3 and edge structure No. 4, which are arranged sequentially to form four layers of cutting edges.
[0013] As a preferred embodiment of the present invention, the bottom of the circulation trench is provided with an ice axe-type stone-discharging platform structure, and the stone-discharging platform structure is arranged in multiple groups in sequence.
[0014] The beneficial effects of this invention are as follows: 1. This invention significantly improves grip and anti-skid performance under all road conditions by setting up a swirl-shaped tread structure, a central tread block, a circulating groove, and edge tread blocks. For icy and slippery road conditions, the four-layer blade structure of the stepped tread block edge structure can efficiently cut through ice and snow and break the water film, allowing the tread block rubber to directly contact the road surface. The central tread block and the corresponding two sets of edge tread blocks continuously grip the ground along the tire circumference. The circulating groove quickly drains water from the road surface. On dry roads, the linkage of each structure ensures uniform force on the tire tread and high grip and fit, comprehensively improving handling stability and driving safety under different road conditions such as ice, snow, wet and slippery, and dry.
[0015] 2. This invention, through the design of a stepped tread block edge structure, an ice axe-style stone-removing platform structure, and tread blocks No. 3 and No. 4, combines excellent self-cleaning and mud-removing properties with highly efficient stone-resistant tire protection. The height difference of the stepped tread block edge structure generates centrifugal force as the tire rolls, which, combined with the spacing of tread blocks No. 3 and No. 4, quickly throws out mud and cuts off adhering mud layers, achieving self-cleaning while ensuring effective tire grip. The circulating groove provides a basic channel for mud and stone removal, and the ice axe-style stone-removing platform structure at the bottom effectively prevents gravel from penetrating deep into the groove, avoiding stones getting stuck and squeezing the edge tread blocks and grooves, while simultaneously throwing the stones out. This significantly reduces the risk of tire deformation and damage due to stones getting stuck, extends tire life, and improves driving durability and reliability in harsh road conditions such as muddy and gravelly conditions.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] like Figures 1 to 4 As shown, this embodiment of the invention provides an off-road tire applicable to all road conditions, including a tire body. The outer surface of the tire body is provided with shoulder tread blocks, edge tread blocks and center tread blocks 5. The shoulder tread blocks include a first tread block 1 and a second tread block 2, which are arranged alternately in the circumferential direction of the tire body. The edge tread blocks include a third tread block 3 and a fourth tread block 4. There are multiple shoulder tread blocks and edge tread blocks. A center tread block 5 is provided at the center of the edge tread blocks.
[0020] Each tread block is integrally protruding onto the tread surface of the tire body, and is a vulcanized structure made of the same rubber material as the tire body. Grooves are reserved between each tread block to accommodate drainage and mud removal in all road conditions. The protrusion height of the tread block is adapted to the overall tread design, taking into account both off-road grip and road surface smoothness. All tread blocks together form a continuous and complete grip tread system, adapting to the driving needs of complex climates and diverse road conditions.
[0021] Among them, the No. 3 tread block 3 and the No. 4 tread block 4 are arranged alternately in the circumferential direction of the tire body, and each shoulder tread block corresponds to each edge tread block.
[0022] The alternating patterns of the two conform to the circumferential contour of the tire body, forming a continuous edge pattern band.
[0023] Two sets of shoulder tread blocks are set in the lateral direction of the tire body, and two sets of edge tread blocks are staggered in the circumferential direction of the tire body.
[0024] Two sets of shoulder tread blocks are symmetrically distributed along the lateral central axis of the tire body, and the staggered edge tread blocks form an interlaced tread pattern in the center of the tread.
[0025] Among them, each set of two edge pattern blocks forms a collection, and the edge pattern blocks of each two collections enclose and form a circular groove 10.
[0026] The circulating groove 10 is a closed groove structure, and its enclosing contour is adapted to the outer edge of the corresponding edge pattern block.
[0027] The central patterned block 5 is located at the center of the circulation groove 10, and the central patterned block 5 and the corresponding two sets of edge patterned blocks combine to form a spiral blade pattern structure.
[0028] The swirl-shaped tread pattern is continuously arranged along the circumference of the tire body, forming the core anti-skid grip tread pattern unit of the tire tread.
[0029] Among them, the center tread block 5 is set at a preset angle with the lateral direction of the tire, and there are multiple center tread blocks 5.
[0030] Multiple center tread blocks 5 are evenly spaced along the circumference of the tire body, and the preset angle of each center tread block 5 is consistent.
[0031] Among them, the edges of patterned block 1, patterned block 2, patterned block 3, patterned block 4 and the central patterned block 5 are all provided with stepped patterned block edge structures, forming a height difference between adjacent edge structures.
[0032] The height difference is continuously set along the edge of the patterned blocks, forming a stepped outline that progresses layer by layer.
[0033] Among them, the stepped pattern block edge structure includes edge structure 6, edge structure 7, edge structure 8, and edge structure 9. Edge structure 6, edge structure 7, edge structure 8, and edge structure 9 are arranged in sequence to form four layers of cutting edge.
[0034] All four cutting edges extend continuously along the edge of the tread blocks, and the direction of the cutting edges matches the rolling direction of the tire body.
[0035] The bottom of the circulation trench 10 is equipped with an ice axe-type stone-discharging platform structure, which is arranged in multiple groups.
[0036] Multiple sets of stone-laying platform structures are evenly distributed along the extension direction of the circulation ditch 10, and protrude from the bottom surface of the ditch to form stone-retaining protrusions.
[0037] Working principle and usage process: When the tire rolls, the raised tread blocks first contact the ground. The shoulder and side tread blocks, which are arranged alternately in the circumference, symmetrically distributed laterally, and staggered in the circumference, ensure that the tread is evenly stressed. The closed-loop grooves 10 formed by multiple sets of side tread blocks, together with the groove gaps between the tread blocks, constitute the basic drainage channel. At the same time, the spiral blade-shaped tread structure formed by the combination of the center tread block 5 and the corresponding two sets of side tread blocks continuously grips the ground along the tire circumference. In conjunction with the multiple center tread blocks 5 arranged at a preset angle and equal intervals to the tire's lateral direction, a centripetal grip force is generated, providing the core grip and anti-skid foundation for various road conditions. On dry roads, contact heat can also be dissipated through the groove gaps to ensure handling stability.
[0038] When driving on icy or slippery surfaces, the four layers of cutting edges formed by the sequentially arranged edge structures 6, 7, 8, and 9 of each tread block cut through the ice and water film layer by layer as the tire rotates. This breaks down the water film barrier between the tire tread and the ground, allowing the rubber to directly contact the road surface to increase friction. Furthermore, the continuous height difference of the tread block edges creates a progressively stepped profile, throwing ice fragments out of the contact area while cutting through the ice and snow. Combined with the gripping force of the rotating blade-shaped tread structure, this effectively prevents tire slippage and deviation. When driving into muddy or gravelly surfaces, the height difference of the stepped edges generates centrifugal force as the tire rolls, quickly throwing out mud adhering to the tread blocks and grooves. The four cutting edges simultaneously cut through the adhering mud layer, achieving self-cleaning and ensuring effective contact between the tire tread and the ground. Upon contact, if gravel enters the circulation groove 10, multiple sets of ice axe-type stone-removing platforms evenly distributed along the extension direction at the bottom of the groove will block the gravel, preventing it from getting stuck at the bottom of the groove. Then, with the help of the tire's rolling circulation motion, the gravel is thrown out of the groove, preventing the gravel from squeezing the groove and causing tread deformation or damage, thus reducing the risk of failure. During the overall driving process, the drainage of the circulation groove 10, the core grip of the swirl-blade pattern structure, the ice and snow cutting or wet slip friction enhancement or mud self-cleaning of the stepped pattern block edge structure, and the efficient stone removal function of the ice axe-type stone-removing platforms work together in unison. Each structure continuously plays its role as the tire rolls, allowing the tire to maintain stable grip, traction, and braking performance when switching between different road conditions such as dry, snowy, wet, muddy, and gravelly conditions, adapting to the complex and ever-changing driving needs of all road conditions.
