Description

Technical Field

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

[0002] The performance requirements for tires in track motocross are extremely high. Tires need to have excellent grip, handling, wear resistance, and water and mud drainage performance. Traditional track motocross tire tread designs often focus on a single performance aspect and are difficult to balance other aspects.

[0003] Therefore, it is still necessary to provide track motorcycle tires to improve grip, handling, wear resistance, and water and mud drainage performance. Utility Model Content

[0004] This utility model provides a solution to the above-mentioned problems.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The second-generation track motorcycle tire includes a tread layer, the top of which is formed with an auxiliary pattern group, a grip pattern group and a connecting pattern group distributed along the equator.

[0007] The auxiliary pattern group includes: side pattern blocks, connecting block group and side pattern blocks arranged in sequence along a direction perpendicular to the equator. The side pattern blocks are located on both sides of the connecting block group and are symmetrically arranged about the equator. The connecting block includes at least two pattern blocks arranged side by side.

[0008] The grip pattern group comprises two spaced grip pattern blocks distributed along a direction perpendicular to the equator.

[0009] The connecting pattern group includes: winged pattern blocks, pattern stripes, and winged pattern blocks distributed along a line perpendicular to the equator. The winged pattern blocks are symmetrical about a straight line perpendicular to the equator, and the pattern stripes are strip-shaped along a direction perpendicular to the equator.

[0010] In one embodiment, along the equator, the auxiliary pattern group, the grip pattern group, and the connecting pattern group are arranged in a meandering pattern.

[0011] In one embodiment, the side tread block is located on the tread layer near the edge, and the top surface of the side tread block has an L-shaped groove with a depth of 1 mm.

[0012] In one embodiment, the number of L-shaped grooves is two.

[0013] In one embodiment, a dividing groove is formed on the patterned strip along the straight line where the equator is located. The bottom of the dividing groove is arc-shaped and the draft angle is 5 degrees.

[0014] In one embodiment, the winged patterned block includes two wing portions and a movable groove spaced between the two wing portions. A connecting groove is formed on the connecting block assembly. The draft angle of both the connecting groove and the movable groove is 5 degrees, and the groove depth is 1.5 mm.

[0015] In one embodiment, the width of the patterned stripe tends to taper from both ends to the middle in the length direction.

[0016] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0017] The side tread blocks on the auxiliary tread pattern are distributed on both sides, providing sufficient friction from the tire edge to prevent sideslip due to insufficient tire edge grip. The connecting block group in the middle position can fully contact the ground when rolling, providing stable grip. The dispersed and relatively sparse grip tread blocks can provide concentrated and stable friction on wet and slippery surfaces. The wing-shaped tread blocks are wing-shaped with gaps between the two wings, which can also improve the flexibility of the tread blocks when gripping the side. They can move together to improve the various friction combinations that enhance grip and have good wear resistance. Attached Figure Description

[0022] 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.

[0023] 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.

[0024] Reference Figure 1-2 This utility model provides a second-generation track motorcycle off-road tire, including a tread layer. The top of the tread layer has an auxiliary tread pattern group 1, a grip tread pattern group 2, and a connecting tread pattern group 3 distributed along the equator. The tread layer serves as the top surface of the tire in contact with the ground, and a reinforcing layer and an inner layer can be sequentially bonded to the bottom as needed. The equator is the center line of the rolling profile of the tire when it is in contact with the ground.

[0025] The auxiliary tread pattern group 1 includes, sequentially distributed along a direction perpendicular to the equator: side tread blocks 11, connecting block group 12, and side tread blocks 11. The side tread blocks 11 are located on both sides of the connecting block group 12 and are symmetrically arranged about the equator. The connecting block group includes at least two tread blocks arranged side by side. When the tire rolls, the side tread blocks, connecting block group 12, and side tread blocks 11 sequentially contact and adhere to the ground. This provides multi-layered friction and rolling performance.

[0026] The grip pattern assembly 2 comprises two spaced grip pattern blocks 21 distributed along a direction perpendicular to the equator. The grip pattern block 21 is, for example, an isosceles trapezoid with 5mm chamfered corners at the two lower bases and a draft angle of 10 degrees. During rolling, the grip pattern assembly 2 is positioned midway between the equator and the edge, balancing the gaps at the top and bottom and providing sufficient and relatively concentrated friction.

[0027] The connecting pattern group 3 includes: wing-shaped pattern blocks 31, pattern stripes 32, and wing-shaped pattern blocks 31 distributed along a line perpendicular to the equator. The wing-shaped pattern blocks 31 are symmetrical about a straight line perpendicular to the equator, and the pattern stripes 32 are stripes along a direction perpendicular to the equator. The wing-shaped pattern blocks 31 are wing-shaped, with two symmetrical wing-like structures. During rolling, the two wing-shaped parts can grip the ground in various combinations, and the two top parts can slightly offset from each other without completely separating, providing stable friction in a flexible and diverse manner.

[0028] In one embodiment, along the equator, the auxiliary pattern group 1, the grip pattern group 2, and the connecting pattern group 3 are arranged in a meandering pattern. Specifically, the auxiliary pattern group 1, grip pattern group 2, and connecting pattern group 3 adopt a meandering distribution pattern along the extension direction of the equator. For example, in the extension direction of the equator, after the connecting pattern group 3 rolls, the next group is still the connecting pattern group 3, followed by the grip pattern group 2 and the auxiliary pattern group 1. Through various coordination methods, the climbing performance on continuous, harsh terrain is improved, resulting in a concentrated, dispersed, and concentrated distribution of friction.

[0029] In one embodiment, the side tread block 11 is located on the tread layer near the edge, and the top surface of the side tread block 11 has an L-shaped groove 111 with a depth of 1 mm. The small L-shaped groove 111 is used to significantly improve the drainage and mud removal performance during driving.

[0030] In one embodiment, there are two L-shaped grooves 111. The two L-shaped grooves 111 are complementary on the side patterned blocks 11, which improves the drainage and sludge removal performance during vehicle operation.

[0031] In one embodiment, a dividing groove 321 is formed on the patterned strip 32 along the straight line of the equator. The bottom of the dividing groove 321 is arc-shaped, and the draft angle is 5 degrees. The arc-shaped bottom of the dividing groove 321 facilitates water drainage and improves the grip of the structure.

[0032] In one embodiment, the wing-shaped tread block 31 includes two wing portions 311 and a movable groove 312 spaced between the two wing portions 311. A connecting groove is formed on the connecting block assembly. The draft angle of both the connecting groove and the movable groove 312 is 5 degrees, and the groove depth is 1.5 mm. The two wing portions 311 are in an open state. When in contact with the ground, the wing-shaped groove pattern is a typical result of multi-objective tire design. Through biomimetic structure and fluid dynamics optimization, it balances multiple requirements such as drainage, grip, noise reduction, durability, and energy consumption.

[0033] In one embodiment, the tread pattern 32 has a width that tapers from both ends to the middle along its length. The wider ends disperse ground pressure, preventing localized stress concentration and reducing uneven wear, while also enhancing lateral grip, providing stronger traction, especially during cornering or braking. The narrower middle section reduces the impact area between the tread block and the ground, lowering noise generated by rubber block vibration during driving; simultaneously, the variable cross-section design disrupts airflow paths, suppressing air column resonance noise.

[0034] 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.
