Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically to a puncture-resistant motorcycle tire. Background Technology
[0002] As the only core component of a two-wheeled motor vehicle in contact with the ground, the technological evolution of motorcycle tires is deeply intertwined with the functional positioning of motorcycles and the needs of riding scenarios, requiring a balance between power transmission, handling stability, and safety protection. Early motorcycle tires largely adopted bicycle tire technology, using natural rubber as the primary material, with simple tire structures that could only meet basic low-speed, short-distance riding needs. With the development of motorcycles towards larger displacement and higher performance, the rise of electric motorcycles necessitates the development of high-rigidity tires adapted to instantaneous high torque, as well as low rolling resistance to reduce energy consumption, driving the continuous upgrading of tire technology towards "scenario customization" and "electrification adaptation."
[0003] There is still room for improvement in the grip performance of current mainstream motorcycle tires, especially in unpaved road conditions: when riding on soft dirt roads, waterlogged roads, sandy areas, or steep slopes, mud can easily get stuck in the tire treads or stones can become lodged in the treads, directly affecting passability and handling stability. At the same time, when riding at high speeds, with insufficient tire pressure, or under heavy loads, tires encountering potholes, gravel, or other poor road conditions are prone to damage from strong impacts, such as sidewall bulges and internal cracks. They also generally have weak impact resistance and insufficient puncture resistance, ultimately leading to abnormal tire wear and significantly shortening their service life. Utility Model Content
[0004] This utility model provides a puncture-resistant motorcycle tire, the specific implementation of which is as follows: A puncture-resistant motorcycle tire includes a tire carcass, a tire sidewall, and a tread located at the contact point between the tire carcass and the ground. The tread has various patterns to adapt to different needs during tire operation, enhancing driving comfort and tire control.
[0005] The tire body is provided with an aramid cushioning layer, and a cushioning film is sandwiched between the ply layers of the aramid cushioning layer. The inner circumferential surface of the tire body is provided with an inner surface rubber, and the inner outer edge of the tire body is provided with a steel wire ring along the circumferential direction. The tread includes ribs and shoulders on both sides of the ribs. Three road block groups are arranged longitudinally on the ribs. Multiple road blocks are arranged circumferentially along the tread circumference in each road block group, and arc-shaped grooves are formed between adjacent road blocks. In this structure, the two ends of the arc-shaped groove tend to be flat, while the middle has a larger slope. This design not only increases the tire's handling when turning, but also increases the tire's heat dissipation capacity due to the multiple arc-shaped grooves.
[0006] Based on the above technical solutions, an aramid buffer layer is set in the tire body, and a buffer sheet is sandwiched between the ply layers of the aramid buffer layer. The buffer sheet is about 1 mm thick, which improves the adhesion and elasticity of the aramid fabric and greatly improves the tire's elasticity and puncture resistance. The innermost inner surface of the tire is a high-elasticity rubber sheet of about 1.5 mm thick, which can enhance the shock absorption effect even on poor road conditions and when the tire is running at high speed, effectively preventing damage to the inner tube and providing riders with a more comfortable and stable experience. The aramid buffer layer also has a conventional aramid skeleton to improve tire rigidity and load-bearing capacity.
[0007] The tire shoulders on both sides have a rotationally symmetrical structure. Each inner side of the tire shoulder has a road block group, and the outer side of the tire shoulder has an annular rubber block connected to the tire sidewall along the circumference of the tread. There are vertical grooves that run around the circumference of the tread between the road blocks and the annular rubber blocks at the tire shoulder. There are multiple wide grooves with arc-shaped inner sides on the outer side of the annular rubber blocks. In this structure, the vertical grooves and the arc-shaped grooves are connected to avoid the road blocks at the tire shoulder from acting on the annular rubber blocks when turning. The vertical grooves and the wide grooves are not connected to avoid the lateral exhaust of internal airflow, thereby reducing noise by reducing the multi-directional exchange of gas.
[0008] There are four main grooves running longitudinally between the five road parcels. The arc-shaped grooves at the tire ribs and shoulders generally present multiple inclined lines, and the distance between each inclined line is the same. The four main grooves in this structure are generally wide and straight, which is conducive to the drainage of water along the circumference of the tire tread when driving at high speed. The overall shape of the arc-shaped grooves as multiple inclined lines can improve the uniformity of the function of the road parcels.
[0009] At the intersection of the main trench and the arc-shaped trench, there is a protrusion, which includes an upper triangular block and a lower triangular block. The upper and lower triangular blocks are connected by a connecting rib. An inclined groove is formed between the upper triangular block and the roadbed. A steel sheet is installed in the inclined groove. The connecting rib in the structure strengthens the rigidity on one side of the upper and lower triangular blocks and uses it as a fulcrum to enhance the stress on the other side of the upper and lower triangular blocks. The steel sheet restricts the range of motion of the upper triangular block.
[0010] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are: 1. In this utility model, the tire cord is changed from nylon cord to aramid cord, and a high-elasticity rubber sheet of about 1 mm thickness is pasted between the cord layers. The innermost inner surface of the tire is provided with a high-elasticity rubber sheet of about 1.5 mm thickness, which greatly improves the elasticity and puncture resistance of the tire. 2. In this utility model, the upper and lower triangular blocks can break up stones on poor road surfaces during tire turning; 3. The arc-shaped design of the wide groove in this utility model facilitates the drainage of accumulated water along the tire sidewall. 4. This utility model has a simple structure, with vertical lines and wide grooves not being conductive, thus reducing noise generation by avoiding multi-directional gas exchange.

[0015] Combination Figure 1 This utility model describes a puncture-resistant motorcycle tire: A puncture-resistant motorcycle tire includes a tire body 2, a tire sidewall 1, and a tread 3 disposed at the contact point between the tire body 2 and the ground. The tread 3 has various patterns to adapt to different needs during tire operation, enhancing driving comfort and tire control. In this structure, the tire body 2 is provided with an aramid buffer layer 5, and a buffer sheet 4 is sandwiched between the ply layers of the aramid buffer layer 5. The inner circumferential surface of the tire body 2 is provided with an inner rubber 6, and the inner outer edge of the tire body 2 is provided with a steel wire ring 7 along the circumferential direction.
[0016] Combination Figure 2 This utility model describes a puncture-resistant motorcycle tire: The tread 3 includes a rib 32 and shoulders 31 on both sides of the rib 32. Three road blocks 34 are arranged longitudinally on the rib 32. Multiple road blocks 34 are arranged circumferentially along the circumference of the tread 3 in each road block 34 group, and an arc groove 35 is formed between adjacent road blocks 34. In this structure, the two ends of the arc groove 35 tend to be flat, while the slope in the middle is larger. This design not only increases the handling of the tire when turning, but also increases the heat dissipation capacity of the tire with multiple arc grooves 35.
[0017] The two tire shoulders 31 have a rotationally symmetrical structure. Each tire shoulder 31 has a set of road blocks 34 on its inner side. The outer side of the tire shoulder 31 has an annular rubber block 311 connected to the tire sidewall 1 along the circumference of the tread 3. There are vertical grooves 313 that surround the circumference of the tread 3 between the road blocks 34 and the annular rubber block 311 at the tire shoulder 31. There are multiple wide grooves 312 with arc-shaped inner sides on the outer side of the annular rubber block 311. In this structure, the vertical grooves 313 and the arc-shaped grooves 35 are connected to avoid the road blocks 34 at the tire shoulder 31 from acting on the annular rubber block 311 when turning. The vertical grooves 313 and the wide grooves 312 are not connected to avoid the lateral exhaust of internal airflow, thereby reducing noise by reducing the multi-directional exchange of gas.
[0018] Four main grooves 33 are longitudinally arranged between the five road plots 34. The arc grooves 35 at the tire ribs 32 and tire shoulders 31 generally present multiple inclined lines, and the distance between each inclined line is the same. In this structure, the four main grooves 33 are generally wide and straight, which is conducive to the drainage of water along the circumference of the tire tread when driving at high speed. The arc grooves 35 generally present multiple inclined lines, which can improve the uniformity of the function of the road plots 34.
[0019] Combination Figure 3 This utility model describes a puncture-resistant motorcycle tire: At the intersection of the main trench 33 and the arc-shaped trench 35, a protrusion 36 is provided. The protrusion 36 includes an upper triangular block 362 and a lower triangular block 361. The upper triangular block 362 and the lower triangular block 361 are connected by a connecting rib 363. An inclined groove 365 is formed between the upper triangular block 362 and the road block 34. A steel plate 364 is provided in the inclined groove 365. In the structure, the connecting rib 363 strengthens the rigidity on one side of the upper triangular block 362 and the lower triangular block 361, and uses this as a fulcrum to enhance the stress on the other side of the upper triangular block 362 and the lower triangular block 361. The steel plate 364 restricts the range of motion of the upper triangular block 362.
[0020] In this embodiment, the arc-shaped wide groove 312 in a puncture-resistant motorcycle tire can enhance the tire's grip at high speeds and also drain accumulated water along the tire sidewall 1 using its arc-shaped design. During driving, the inclined sides of the upper triangular block 362 and the lower triangular block 361 disrupt the airflow in the main groove 33 without affecting the drainage effect of the main groove 33. When a stone gets stuck in the arc-shaped groove 35, the moving sides of the upper triangular block 362 and the lower triangular block 361 engage the stone through stress during tire turning to remove the stuck stone.
[0021] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
