Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a second-generation forest trail motorcycle off-road tire. Background Technology

[0002] As the part of a motorcycle that comes into direct contact with the ground, tires play a crucial role in supporting the weight of the vehicle, bearing its load, transmitting traction and braking torque, ensuring the adhesion between the wheels and the road surface, and reducing and absorbing vibrations and impacts during vehicle operation. Therefore, tires have a direct impact on the vehicle's handling stability, driving safety, and comfort.

[0003] Traditional trail tires often face the following problems in hard gravel, mud, and mixed terrain:

[0004] Insufficient grip: A single tread pattern design cannot adequately balance longitudinal driving force and lateral adhesion, easily leading to slippage. Poor wear resistance: Concentrated stress causes rapid wear of the tread blocks, reducing tire life. Poor mud clearance: Inadequate groove design allows mud and gravel to accumulate on the tread, affecting traction efficiency. Utility Model Content

[0005] This utility model provides a second-generation forest trail motorcycle off-road vehicle tire that solves the above-mentioned problems.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The second-generation forest trail motorcycle off-road tire includes a tread layer on which a plurality of first tread groups and second tread groups are formed alternately along the equator of the tire. The first tread group includes at least three rectangular protrusions, and the second tread group includes two rectangular protrusions arranged side by side, with a gap groove formed between two adjacent rectangular protrusions.

[0008] It also includes trapezoidal pattern blocks set on both sides of the first pattern group, and multiple trapezoidal composite pattern blocks located on both sides of the equator between the first and second pattern groups;

[0009] The trapezoidal patterned blocks and the trapezoidal composite patterned blocks are V-shaped.

[0010] In one embodiment, the plurality of trapezoidal composite pattern blocks are divided into a first trapezoidal composite pattern block and a second trapezoidal composite pattern block according to their vertical distance from the equator. The distance of the first trapezoidal composite pattern block from the equator is greater than the distance of the second trapezoidal composite pattern block from the equator.

[0011] In one embodiment, a K-shaped groove is formed on the top surface of the trapezoidal patterned block.

[0012] In one embodiment, the height of the first pattern group and the second pattern group is 13.5 mm, and the two sides of the first pattern group and the second pattern group away from the equator are also formed with chamfers at an angle of 12.5 degrees to the top surface.

[0013] In one embodiment, the top edges of the first trapezoidal composite patterned block and the second trapezoidal composite patterned block on the side away from the equator are formed with a chamfer at a 25-degree angle to the top surface.

[0014] In one embodiment, the bottom of the tread further includes a reinforcing layer and an inner tube layer.

[0015] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0016] The tread layer has alternating first and second tread patterns along the equator. The first and second tread patterns alternate longitudinally with the ground, which can reduce local wear and improve tire wear resistance. In addition, the trapezoidal composite tread blocks on both sides form a V-shape, which can achieve a dynamic balance between longitudinal driving force and lateral adhesion force when rolling, providing more stable grip and balancing the friction distribution of the tire when rolling, providing overall stable grip.

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0021] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0022] Reference Figure 1-2 This utility model provides a second-generation off-road motorcycle tire, including a tread layer 1. The tread layer 1 has multiple alternating first tread pattern groups 2 and second tread pattern groups 3 distributed along the tire's equator. The first tread pattern group 2 includes at least three rectangular protrusions 4, and the second tread pattern group 3 includes two rectangular protrusions 4 arranged side-by-side, with a gap 5 formed between adjacent rectangular protrusions 4. The tread layer 1 is the surface of the tire, with the equator being the center line of tire contact with the ground. The first tread pattern group 2 and the second tread pattern group 3 are distinguished by the different numbers of rectangular protrusions 4. Their alternating distribution along the tire's equator provides layered friction during rolling, dispersing ground pressure, reducing localized wear, and improving tire wear resistance.

[0023] It also includes trapezoidal tread blocks 6 on both sides of the first tread pattern group 2, and multiple trapezoidal composite tread blocks 7 located on both sides of the equator between the first tread pattern group 2 and the second tread pattern group 3. The trapezoidal tread blocks 6 and the trapezoidal composite tread blocks 7 are V-shaped. The surface of the trapezoidal composite tread block 7 is a right-angled trapezoid, or the trapezoidal composite tread blocks 7 and the trapezoidal composite tread blocks 6 on both sides together form a V-shaped or figure-eight shaped tread line, achieving a dynamic balance between longitudinal driving force and lateral adhesion. This avoids concentrated wear on a single area of ​​the tire while providing good traction.

[0024] Preferably, the plurality of trapezoidal composite patterned blocks 7 are divided into a first trapezoidal composite patterned block 71 and a second trapezoidal composite patterned block 72 according to their vertical distance from the equator. The distance of the first trapezoidal composite patterned block 71 from the equator is greater than the distance of the second trapezoidal composite patterned block 72 from the equator. The first trapezoidal composite patterned block 71 and the second trapezoidal composite patterned block 72 have the same shape and size. The distances of the first trapezoidal composite patterned block 71, the second trapezoidal composite patterned block 72, and the trapezoidal patterned block 6 from the equator gradually increase, thereby forming a multi-directional drainage channel during rolling, enhancing mud discharge, and ensuring efficient discharge of mud and gravel.

[0025] Preferably, the top surface of the trapezoidal patterned block 6 has a K-shaped groove 61. The added K-shaped groove 61 on the patterned block can improve grip.

[0026] Preferably, the height of the first tread pattern group 2 and the second tread pattern group 3 is 13.5 mm, and the two sides of the first tread pattern group 2 and the second tread pattern group 3 away from the equator are also formed with chamfers at an angle of 12.5 degrees to the top surface. The chamfers and the top surface form a 12.5-degree angle, and the flexible deformation capability allows the tire to smoothly transition between hard road surfaces and soft mud roads, reducing vibration.

[0027] Preferably, the top edges of the first trapezoidal composite tread block 71 and the second trapezoidal composite tread block 72 on the side away from the equator are chamfered at a 25-degree angle to the top surface. The smooth edges on both sides reduce edge wear and tire vibration.

[0028] Preferably, the bottom of the tread further includes a reinforcing layer 8 and an inner tube layer 9. The reinforcing layer 8 of this patent is made of high-strength nylon cord yarn. The reinforcing layer 8 consists of two layers of high-strength nylon cord yarn placed in a cross-overlay manner, and the reinforcing layer 8 is folded back along the steel wire ring to the tire sidewall to form a circumference, which enhances the tire's impact resistance and support capabilities, enabling the tire to withstand high loads.

[0029] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
