Technical Field
[0001] The utility model relates to the technical field of tires, in particular to a bus tire. Background Art
[0002] When a bus travels on an urban road, it needs to start and brake continuously. Therefore, it is very important for a bus tire to have sufficient driving force and braking performance. In terms of the driving safety of a bus, it is necessary to have excellent wear resistance and good drainage performance; traditional bus tires generally adopt a design of zigzag grooves and high-saturation patterns. These design features ensure the basic driving performance of the tire and a certain wear life, but at the same time increase the rolling resistance of the tire and the fuel consumption of the vehicle, which does not conform to the trend of energy conservation and environmental protection.
[0003] Based on this, a bus tire is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

[0006] A bus tire includes: a tread crown, a tread shoulder and a tread sidewall. The tread crown, the tread shoulder and the tread sidewall constitute the surface of the tire. The tread crown is the surface perpendicular to the circular cross-section of the tire, the tread sidewall is the surface parallel to the circular cross-section of the tire, and the tread shoulder is the connecting part between the tread crown and the tread sidewall; five longitudinal main grooves are arranged on the surface of the tread crown. The five longitudinal main grooves divide the tread crown into tread shoulder blocks at both sides of the tread shoulder and four tread crown blocks in the middle of the tread crown.
[0007] On the basis of the above technical solutions, the utility model also provides the following optional technical solutions:

For every three of the first tread shoulder grooves, the vertex two of the first one is connected to the vertex one of the third one through a second tread shoulder groove.
[0009] In an optional solution: a plurality of tread crown grooves are arranged on the surface of the tread crown block. The tread crown grooves are arranged in a circumferential array on the tread crown block. The tread crown grooves are Z-shaped.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] In one embodiment, as Figure 1 - Figure 3As shown in the figure, a bus tire includes: a tread crown 100, a tread shoulder 200, and a tread sidewall 300. The tread crown 100, the tread shoulder 200, and the tread sidewall 300 constitute the surface of the tire. The tread crown 100 is a surface perpendicular to the circular cross-section of the tire, the tread sidewall 300 is a surface parallel to the circular cross-section of the tire, and the tread shoulder 200 is the connecting part between the tread crown 100 and the tread sidewall 300. Five longitudinal main grooves 400 are provided on the surface of the tread crown 100. The five longitudinal main grooves 400 divide the tread crown 100 into tread shoulder blocks 500 at both sides of the tread shoulders 200 and tread crown blocks 600 in the middle of the four tread crowns 100. By providing multiple longitudinal main grooves 400, the friction with air during driving is relatively small, which helps to reduce the noise and vibration generated by the friction between the tire and the road surface, thereby providing a lower noise level, reducing the energy loss during driving, reducing fuel consumption, and conforming to the trend of energy conservation and environmental protection.
[0021] In this embodiment, as Figure 3 shown, a plurality of first tread shoulder grooves 501 are provided on the surface of the tread shoulder block 500. The first tread shoulder grooves 501 are arranged in a circumferential array on the tread shoulder block 500. The first tread shoulder grooves 501 are Z-shaped. The two corner vertices of the Z-shaped first tread shoulder grooves 501 are vertex one 502 and vertex two 503 respectively. For every three of the first tread shoulder grooves 501, the vertex two 503 of the first one is connected to the vertex one 502 of the third one through a second tread shoulder groove 504. The thin and shallow first tread shoulder grooves 501 and the second tread shoulder grooves 504 are arranged vertically and horizontally, which is conducive to assisting the longitudinal main grooves 400 in draining water, increasing the driving force and braking force of the tire, increasing the wear resistance of the tire, and having a good heat dissipation effect.
[0022] In one embodiment, as Figure 2 shown, a plurality of tread crown grooves 601 are provided on the surface of the tread crown block 600. The tread crown grooves 601 are arranged in a circumferential array on the tread crown block 600. The tread crown grooves 601 are Z-shaped, which assist the longitudinal main grooves 400 in draining water, increasing the driving force and braking force of the tire, and increasing the wear resistance of the tire.
[0023] In one embodiment, as Figure 2 shown, the tread shoulder block 500 is wider than the tread crown block 600, which increases the shoulder rigidity and prevents uneven wear on the shoulders.
[0024] In one embodiment, as Figure 1 shown, the first tread shoulder grooves 501 and the second tread shoulder grooves 504 have the same depth. The widths and depths of the first tread shoulder grooves 501 and the second tread shoulder grooves 504 are narrower and shallower than those of the tread crown grooves 601. While increasing the wear resistance of the tire, it greatly reduces the resistance during driving, reduces the energy loss during driving, reduces fuel consumption, and conforms to the trend of energy conservation and environmental protection.
[0025] In one embodiment, as Figure 1 shown, the five longitudinal main grooves 400 are in a small wavy shape. The depth and width of the longitudinal main grooves 400 are the same. The five longitudinal main grooves 400 being in a small wavy shape can better conform to the air flow and reduce the driving resistance. The longitudinal grooves with the same depth and width can reduce the noise and vibration during tire driving, thereby improving the driving comfort.
[0026] The above embodiment discloses a bus tire. By providing multiple longitudinal main grooves 400, the friction with air during driving is relatively small, which helps to reduce the noise and vibration generated by the friction between the tire and the road surface, thereby providing a lower noise level, reducing the energy loss during driving, reducing fuel consumption, and conforming to the trend of energy conservation and environmental protection. The longitudinal main grooves 400 are in a small wavy shape to better conform to the air flow and reduce the driving resistance. The surface of the shoulder block 500 is provided with a plurality of first shoulder grooves 501. For every three of the shoulder grooves 501, the apex two 503 of the first one is connected to the apex one 502 of the third one through the second shoulder groove 504. The thin and shallow first shoulder grooves 501 and the second shoulder grooves 504 are arranged in a crisscross pattern, which is beneficial to assisting the longitudinal main grooves 400 in draining water, increasing the driving force and braking force of the tire, increasing the wear resistance of the tire, and having a good heat dissipation effect. The width and depth of the first shoulder grooves 501 and the second shoulder grooves 504 are narrower and shallower than those of the crown grooves 601. While being beneficial to assisting the longitudinal main grooves 400 in draining water, increasing the driving force and braking force of the tire, and increasing the wear resistance of the tire, the resistance during driving is greatly reduced. The surface of the crown block 600 is provided with a plurality of crown grooves 601 to assist the longitudinal main grooves 400 in draining water, increasing the driving force and braking force of the tire, and increasing the wear resistance of the tire.
[0027] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
