Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle tires, in particular to a cruiser motorcycle tire. Background Art

[0002] Nowadays, with the rapid development of the domestic economy, the motorcycle industry has become much hotter in recent years, and there are many types of motorcycles, such as sports motorcycles, street motorcycles, retro motorcycles, cruiser motorcycles, etc., with diverse models.

[0003] At present, in order to increase the grip of the tire, the number and area of the patterns on the tire surface are often increased. However, the blind increase in the area of the pattern particles will not only cause material consumption and excessive cost, but also make the tire become relatively heavy, resulting in a decline in the riding and driving experience.

[0004] Therefore, there is still a need for a cruiser motorcycle tire that solves the above problems. Content of the Utility Model

[0005] The utility model provides a cruiser motorcycle tire that solves the above problems.

[0006] The purpose of the utility model is achieved by the following technical solutions:

[0007] A cruiser motorcycle tire includes a tread layer. First and second pattern unit groups are formed on the tread layer and are distributed along the center line and on both sides of the center line respectively. The first and second pattern unit groups both include a first pattern block, a second pattern block, and a third pattern block. The first pattern block, the second pattern block, and the third pattern block are separated by main grooves.

[0008] Friction patterns that are continuously meandering and bent are formed between the main grooves on both sides of the center line.

[0009] In one embodiment, the second pattern block and the third pattern block are alternately distributed along the center line direction near the edge of the tread.

[0010] In one embodiment, the two main grooves on both sides of the center line are symmetric in shape and are offset and staggered along the center line.

[0011] In one embodiment, connecting ribs are formed in some of the main grooves between the first pattern block and the second pattern block, and between the first pattern block and the third pattern block.

[0012] In one embodiment, the height of the connecting rib is 80% of the depth of the main groove.

[0013] In one embodiment, extension grooves extending towards the friction patterns are formed on the main grooves, and the width of the extension grooves gradually decreases in the direction towards the friction patterns.

[0014] In one embodiment, a buffer layer and a reinforcement layer are sequentially connected to the inner side of the tread layer. A bead ring is accommodated near the position for docking with the wheel hub in the reinforcement layer.

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

[0016] The first tread blocks, the second tread blocks, and the third tread blocks are arranged at intervals in the main groove. The first tread blocks, the second tread blocks, and the third tread blocks are respectively located near the edge of the tire. The main grooves between the two tread unit groups enclose friction patterns that are spaced and meandering. When driving, it can provide stable friction while avoiding excessive tread block structures at the top of the tread layer, resulting in excessive materials. While achieving lightweight, the first tread blocks, the second tread blocks, and the third tread blocks arranged at intervals provide stable friction at the edge, and the middle friction patterns are tortuous, which can disperse stress and prevent the tread blocks from cracking.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present utility model will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the figures denote the same or similar structures, and thus their repeated description will be omitted.

[0021] The words expressing positions and directions described in the present utility model are illustrated by taking the drawings as examples, but can be changed according to needs, and all changes are included in the protection scope of the present utility model.

[0022] Refer to Figure 1-2The utility model provides a prince-type motorcycle tire, comprising a tread layer 1, on which a first pattern unit group 2 and a second pattern unit group 3 are formed, which are distributed along a center line and are respectively located on both sides of the center line. The first pattern unit group 2 and the second pattern group both include a first pattern block 4, a second pattern block 5 and a third pattern block 6, and the first pattern block 4, the second pattern block 5 and the third pattern block 6 are separated by a main groove 7.

[0023] The main grooves 7 on both sides of the center line form a continuous tortuous friction pattern 8. The first pattern block 4, the second pattern block 5 and the third pattern block 6 are arranged separately and spaced apart, which can provide stable and dispersed friction on both sides, and have strong flexibility to overcome external extrusion. In addition, the tortuous friction pattern 8 is a plurality of Z-shaped bends as a whole, which provides stable friction when the vehicle is driving. In addition, the main groove 7 covers the tread to form a drainage groove as a whole, which improves the drainage performance and can ensure good grip on rainy days.

[0024] In one embodiment, the second pattern blocks 5 and the third pattern blocks 6 are alternately distributed along the center line direction near the edge of the tread. The second pattern blocks 5 and the third pattern blocks 6 are alternately distributed, and the first pattern blocks 4 and the second pattern blocks 5 have different shapes. When they contact the ground in sequence, they provide different friction forces to improve the passability on the road surface.

[0025] In one embodiment, the two main grooves 7 on both sides of the center line are symmetrical in shape and staggered along the center line. The pattern blocks on both sides are respectively symmetrical in center, and when contacting the ground, the patterns on both sides contact the ground in turn, ensuring a good sense of hierarchy and passability.

[0026] In one embodiment, connecting ribs 9 are formed in part of the main grooves 7 between the first pattern block 4 and the second pattern block 5, and between the first pattern block 4 and the third pattern block 6. The connecting ribs 9 are connected to form an interlocking connection, which improves the rigidity of the tire tread, thereby improving the straight-line traction of the tire on various road surfaces, and enhancing the braking and handling performance.

[0027] In one embodiment, the height of the connecting rib 9 is 80% of the depth of the main groove 7. This can increase the connection stress between the connecting blocks and also increase the rolling friction.

[0028] In one embodiment, an extension groove 10 extending toward the friction pattern 8 is formed on the main groove 7, and the width of the extension groove 10 gradually decreases in the direction close to the friction pattern 8. The inclined groove is non-parallel and gradually widens to ensure its drainage performance.

[0029] In one embodiment, a buffer layer 11 and a reinforcement layer 12 are sequentially connected to the inner side of the tread layer 1, and a bead 13 is accommodated near the position for docking with a wheel hub in the reinforcement layer 12.

[0030] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
