Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically a tire structure with low rolling resistance and high handling. Background Technology
[0002] A tire is a ring-shaped rubber product installed on the wheels of a vehicle. Its main functions are to support the weight of the vehicle, transmit driving force and braking force, and absorb ground impacts to enhance driving stability and safety. Low rolling resistance and high handling tires are a technological upgrade that optimizes the design of traditional tires to reduce rolling resistance and improve handling performance at the same time.
[0003] Existing technologies mainly use flat tread designs. A single compound design can only meet one tire performance requirement. When ensuring rolling resistance performance, handling performance will be somewhat reduced. In traditional flat tread designs, the upper tread usually has better handling, while the lower tread is mainly used to optimize rolling resistance, but its handling is slightly worse than that of the upper tread. Generally, tires with reduced rolling resistance have poorer handling. Utility Model Content
[0004] The purpose of this invention is to provide a tire structure with low rolling resistance and high handling to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A tire structure with low rolling resistance and high handling includes:
[0007] First side tire crown;
[0008] The second side crown is located on one side of the top of the first side crown;
[0009] It also includes a transition zone and a tread, wherein the transition zone is disposed between the first side crown and the second side crown, and the tread is disposed on top of the first side crown and the second side crown.
[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0011] In one alternative: the width variation point of the second side tread rubber compound = E = 30%-50% of the contact surface.
[0012] In one alternative: drainage grooves are provided on the top of both the first and second side tire crowns.
[0013] In one alternative: the tread is made of a high-silica rubber composite material, wherein silica accounts for approximately 30%-40%.
[0014] In one alternative: the first side crown is made of low-density rubber.
[0015] In one alternative: the second side tread is made of high-density rubber.
[0016] In one alternative: the transition zone is made of a gradient-varying composite material.
[0017] In one alternative: the tread on the second side of the tire crown is supplemented with micro-granular rough texture.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention improves handling performance while maintaining rolling resistance by setting a first side crown, a second side crown, and a transition zone, thereby increasing the distribution of the outer control rubber material while maintaining the thickness of the low rolling resistance rubber material in the middle.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In one embodiment, such as Figures 1-3 As shown, a tire structure with low rolling resistance and high handling includes: a first side crown 100, a second side crown 200, a transition zone 300, and a tread 301. The second side crown 200 is disposed on one side of the top of the first side crown 100. The transition zone 300 is disposed between the first side crown 100 and the second side crown 200. The tread 301 is disposed on the top of the first side crown 100 and the second side crown 200. The first side crown 100 optimizes rolling resistance, while the second side crown 200 directly contacts the ground, bearing grip and handling. The combination of the two can maintain the thickness of the low rolling resistance rubber in the middle and increase the distribution of the control rubber on the outer side to ensure rolling resistance while improving handling performance.
[0026] In one embodiment, such as Figure 2As shown, the width variation point of the rubber compound on the second side of the tread 200 is E = 30%-50% of the contact surface; improving the distribution of the rubber compound on the tread ensures that the rubber compound on the second side of the tread 200 improves handling performance, while the rubber compound on the first side of the tread 100 remains unchanged to maintain the rolling resistance performance of the product.
[0027] In one embodiment, such as Figure 2 As shown, drainage grooves 400 are provided on the top of both the first side crown 100 and the second side crown 200; this improves the tire's drainage performance on wet and slippery roads, effectively reduces water film phenomenon, and enhances grip.
[0028] In one embodiment, such as Figure 2 and Figure 3 As shown, the tread 301 is made of a high-silica rubber composite material, in which silica accounts for about 30%-40%; the high-silica material provides better molecular chain slippage performance at the micro level, thereby reducing energy loss and achieving a significant reduction in rolling resistance.
[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the first side crown 100 is made of low-density rubber to ensure reduced energy loss during operation.
[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the second side tread 200 is made of high-density rubber, which improves the tire's grip and handling on dry or wet surfaces.
[0031] In one embodiment, such as Figure 2 and Figure 3 As shown, the transition zone 300 is made of a gradient-changing composite material, achieving a smooth transition between the first side crown 100 and the second side crown 200.
[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the tread 301 on the second side crown 200 is provided with micro-granular rough texture to improve friction with the ground.
[0033] The above embodiments disclose a tire structure with low rolling resistance and high handling. The rolling resistance is optimized by the first side crown 100, and the second side crown 200 directly contacts the ground to bear the grip and handling. The combination of the two can maintain the thickness of the low rolling resistance rubber in the middle and increase the distribution of the control rubber on the outside to ensure rolling resistance while improving handling performance. The transition zone is set to achieve a smooth transition between the first side crown 100 and the second side crown 200.
[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
