Description

Technical Field

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

[0002] In high-speed motorcycle racing, tires need to have grip, wear resistance, easy control, and timely heat dissipation. In addition to the above functions, tires also need to be able to quickly drain water and sand, and promptly drain the sand and accumulated water that the tires are in contact with the ground, so that the tires are in direct contact with the ground instead of contacting the sand or water film on the ground. This can increase the tire's grip and reduce the resistance of sand and stones to the tire, making the tire easier to drive and easier to speed up, which is of great significance for high-speed racing.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN211995020U, patent name: A low-profile high-speed racing vacuum tire) is: including a tire body, the outer ring of the tire body is a tread crown, and the side surfaces of the tire body from the outer ring to the inner ring are shoulder, sidewall, and toe in sequence, characterized in that the tire body has an aspect ratio of 0.7; the tread crown is provided with a pattern, and the pattern includes a double center groove arranged in the center of the tread crown and streamlined pattern grooves arranged on both sides of the double center groove; the streamlined pattern grooves are formed by alternating first pattern grooves and second pattern grooves; the length of the first pattern groove is less than 1 / 3-1 / 2 of the length of the second pattern groove.

[0004] It can be seen from the above implementation scheme that the tread grooves of the low-profile high-speed racing vacuum tire are mainly used to increase the friction between the tire and the ground, and do not have the function of quickly draining water and sand, which is not conducive to speeding up and driving the tire during high-speed competition. Utility Model Content

[0005] The utility model overcomes the shortcomings of the prior art. A plurality of drainage channels are arranged on the tire crown. Inlet slopes and outlet slopes are arranged at both ends of the drainage channels, so that water, sand, dust and the like can be quickly discharged from under the wheels when the wheels are rolling, thereby reducing the situation where the wheels and the road are isolated by water and sand, making the wheels have stronger grip. The rapid emptying of sand and dust also makes the wheels roll more lightly and quickly.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] A high-speed racing motorcycle tire comprises a tread crown and sidewalls connected to both sides of the tread crown. The tread crown is provided with a plurality of drainage channels. Both ends of the drainage channels are provided with an inlet slope and an outlet slope. Sand and water slide into the drainage channel from the inlet slope and then slide out of the drainage channel from the outlet slope.

[0008] Furthermore, the drainage channel includes a first drainage channel, a second drainage channel and a third drainage channel. The first drainage channel includes a rolling channel and a turning channel that are connected. The second drainage channel is arranged parallel to the rolling channel. The third drainage channel is arranged parallel to the turning channel. The third drainage channel and the turning channel extend to both sides of the crown.

[0009] Furthermore, the bottom width of the first drainage channel is narrower than the upper opening thereof, a first inlet slope is arranged at one end of the rolling channel away from the turning channel, and a first outlet slope is arranged at one end of the turning channel away from the rolling channel.

[0010] Furthermore, the bottom width of the second drainage channel is narrower than the upper opening thereof, and a second inlet slope and a second outlet slope are respectively provided at both ends of the second drainage channel;

[0011] The bottom width of the third drainage channel is narrower than the upper opening thereof, and a third inlet slope and a third outlet slope are respectively arranged at two ends of the third drainage channel.

[0012] Furthermore, the sidewall is provided with a steel ring clamping surface, and the angle of the steel ring clamping surface is from degrees to degrees.

[0013] Furthermore, a limiting convex ring is provided on the clamping surface of the steel ring.

[0014] Furthermore, the land-to-sea ratio of the crown is 92:8.

[0015] Furthermore, the crown arc angle is 48 degrees to 52 degrees.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figures 1 to 5 As shown, a high-speed racing motorcycle tire comprises a crown 1 and sidewalls 2 connected to both sides of the crown 1. The crown 1 is provided with a plurality of drainage channels, and both ends of the drainage channels are provided with an inlet slope and an outlet slope. Sand and water slide into the drainage channel from the inlet slope and then slide out of the drainage channel from the outlet slope, so that when the wheel rolls, water, sand, dust, etc. can be quickly discharged from under the wheel, reducing the situation where water and sand isolate the wheel from the road surface, making the wheel have stronger grip, and quickly emptying the sand and stones also makes the wheel roll more lightly and quickly. Due to the design of the drainage channel, the land-sea ratio of the crown (1) reaches 92:8, thereby enhancing the grip and wear resistance of the crown, and making the driver more accurate in controlling the tire.

[0027] The crown arc angle a is 48 to 52 degrees. Compared with traditional tires, the crown 1 has a larger coverage area, so when the wheel tilts and turns, the side of the wheel can also be supported by the crown 1, which ensures that the wheel can still maintain good grip when turning, meeting the needs of high-speed racing wheels for fast turning.

[0028] The drainage channel includes a first drainage channel 101, a second drainage channel 102 and a third drainage channel 102. The first drainage channel 101 includes a rolling channel 10A and a turning channel 10B that are connected. The second drainage channel 102 is arranged in parallel with the rolling channel 10A. The third drainage channel 102 is arranged in parallel with the turning channel 10B. The third drainage channel 102 and the turning channel 10B extend to both sides of the crown 1. The bottom width of the first drainage channel 101 is narrower than the upper end opening thereof. The rolling channel 10A is far away from the turning channel 10B. A first inlet slope 1011 is provided at one end, a first outlet slope 1012 is provided at one end of the turning track 10B away from the rolling track 10A, the bottom width of the second drainage channel 102 is narrower than the upper opening, and the second inlet slope 1021 and the second outlet slope 1022 are provided at both ends of the second drainage channel 102; the bottom width of the third drainage channel 103 is narrower than the upper opening, and the third inlet slope 1031 and the third outlet slope 1032 are provided at both ends of the third drainage channel 103. The bottom width of the drainage channel is narrower than the upper opening, which is conducive to the discharge of water and dust at the bottom of the drainage channel from the opening. The second drainage channel 102 and the rolling track 10A are arranged along the rolling direction of the wheel and close to the center of the crown 1, which is conducive to quickly discharging sand and water at the contact point between the tire and the ground. The third drainage channel 102 and the turning track 10B form a certain angle with the rolling direction of the wheel and extend in the opposite direction to the forward movement of the wheel, which is conducive to discharging water and sand and dust at the bottom of the wheel toward both sides of the wheel.

[0029] The sidewall 2 is provided with a steel rim clamping surface 201. The angle of the clamping surface of the traditional tire steel rim 201 is 5 degrees, while the angle of the clamping surface 201 of the utility model is 12 to 14 degrees, which is conducive to the close fit between the tire and the wheel hub. In the case of under-inflation of the tire or sideways movement of the wheel, the tire and the wheel hub will not easily separate, thereby increasing the safety of use.

[0030] The steel ring clamping surface 201 is provided with a limiting convex ring 2011, which is beneficial for clamping the wheel hub when the tire and the wheel hub are matched, thereby further increasing the tightness of the combination of the two.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
