Description

Technical Field

[0001] This invention relates to the field of automotive tire technology, specifically to an off-road tire with a mechanical wrench-shaped tread pattern. Background Technology

[0002] Existing off-road tires are positioned between all-terrain (AT) and manual (MT) tires, with performance leaning more towards AT tires. They are the most complex type of off-road tire; more contact patch rubber indicates better handling, while fewer tread patterns and deeper grooves indicate better off-road performance. When vehicles travel on unpaved surfaces such as deserts and muddy roads, to ensure tire traction, the volume ratio of grooves in the tread structure is often increased, thereby increasing the tire's ability to trap mud and sand and improving traction. Additionally, lowering tire pressure is sometimes used to improve the tire's ability to sink into mud and sand, thus enhancing traction. Off-road tires, through their rugged tread design and increased tread groove area, ensure traction on gravel and muddy surfaces; however, this results in decreased performance on paved roads, increased noise, and higher rolling resistance, leading to increased fuel consumption.

[0003] Based on this, a mechanical wrench-type tread pattern off-road tire is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0004] The purpose of this invention is to provide an off-road tire with a mechanical wrench-shaped tread pattern to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mechanical wrench-type tread pattern off-road tire includes a tire body. The tread structure of the tire body consists of a central part and a side part. The central part consists of two sets of tread blocks. The side part is located on both sides of the central part. The side part is provided with a plurality of first side tread blocks and second side tread blocks, and the first side tread blocks and second side tread blocks are alternately arranged.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In this embodiment, as Figures 1-3 As shown, a mechanical wrench-type tread structure off-road tire includes a tire body. The tread structure of the tire body consists of a central part 1 and a side part 2. The central part 1 consists of two sets of tread blocks. The side part 2 is located on both sides of the central part 1. The side part 2 is provided with a plurality of first side tread blocks 7 and second side tread blocks 8. The first side tread blocks 7 and second side tread blocks 8 are alternately arranged, which facilitates the use of the mechanical wrench-type tread structure off-road tire and improves wear resistance.

[0024] Among them, such as Figure 2 As shown, the central part 1 is composed of a first patterned block 3, a second patterned block 4, a third patterned block 5, and a fourth patterned block 6. The first patterned block 3 and the second patterned block 4 are arranged on the left and right sides of the central part 1, and the third patterned block 5 and the fourth patterned block 6 are arranged on the upper and lower sides of the first patterned block 3. Steel plates are provided on each patterned block, which can divide the rigidity of the patterned block and reduce wear performance.

[0025] Among them, such as Figure 1 and Figure 2 As shown, steps 10 are provided on the edges of the tread blocks in the center 1 and the side 2. The width of the steps 10 is 2mm, which increases the contact area of ​​the off-road tire and improves the handling performance of the off-road tire with the mechanical wrench-type tread structure.

[0026] Among them, such as Figure 1 and Figure 2 As shown, a longitudinal groove 11 is provided at the junction of the central part 1 and the side part 2. A transverse groove 12 is provided on the opposite side of the first side tread block 7 and the second side tread block 8. Long strip-shaped tread ribs 9 are provided at the bottom of the transverse groove 12 and the longitudinal groove 11, which helps to improve the traction performance of the mechanical wrench-type tread structure off-road tire, plays a role in timely drainage and mud removal, and has strong self-cleaning properties.

[0027] Among them, such as Figure 2 and Figure 3 As shown, the first tread block 3 and the second tread block 4 have a mechanical wrench-shaped tread structure. The mechanical wrench-shaped tread structure is set as a double-headed "wrench" shape, which makes the stress in the center part 1 of the tread structure evenly distributed and improves the service life of the off-road tire with the mechanical wrench-shaped tread structure.

[0028] Among them, such as Figure 3 As shown, the first patterned block 3 has L2, L3, L4, L5, and L6 on its side. L2 and L5 are the short sides, and L3 and L4 are the long sides. L2, L3, L4, and L5 are designed with non-equal widths. The long sides L3 and L4 are set to a specific ratio with the short sides L2 and L5. The length of the side of the first patterned block 3 changes with L4 as the change value. The length of L4 is determined with L6 as the center, and is set to L4 > L3 > L5 > L2. The shape of the mechanical wrench-type patterned structure is determined by the change in the length of L4.

[0029] Among them, such as Figure 3 As shown, the included angle between the first tread block 3 and the second tread block 4 is set as α, and the angle range is set between 40° and 90°. By controlling the size of angle α, it is easy to control the size of the wrench shape and ensure the normal use of the tire.

[0030] Among them, such as Figure 3 As shown, the included angle between the center of the first tread block 3 and the second tread block 4 is set to b, and the angle range is set between 100° and 160° to improve the wear resistance of the mechanical wrench-type tread structure off-road tire.

[0031] Among them, such as Figure 3 As shown, the included angle between the sides L2 and L3 of the first tread block 3 is set to c, and the angle range is set between 50° and 110°, which strengthens the adhesion of the mechanical wrench-type tread structure off-road tire on unpaved roads.

[0032] Among them, such as Figure 3 As shown, the short side at the intersection of the first patterned block 3 and the second patterned block 4 is set as L1. The length range of L1 is determined according to a, b, and c, which facilitates control over the size of the wrench shape of the mechanical wrench-type patterned structure.
