Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a wear-resistant electric bus tire with strong grip. Background Technology

[0002] In recent years, with the popularization of new energy buses, pure electric buses have gradually replaced traditional fuel buses due to their advantages such as low noise and zero emissions. As a core component of urban public transportation, the performance of bus tires directly affects the vehicle's safety, economy, and environmental friendliness. Because buses have long daily operating mileage, large passenger capacity, and frequent starts and stops, tires need to possess superior load-bearing capacity, excellent wear resistance, and stable grip. Modern bus tires employ three innovative technologies: a high-rigidity carcass structure to ensure load-bearing strength, a silicone-modified tread compound to improve energy efficiency, and an asymmetric tread pattern design to enhance braking performance on wet roads. For new energy buses, anti-torque deformation sidewalls and intelligent tire pressure monitoring systems have been developed, achieving a dual breakthrough in safety and energy efficiency.

[0003] However, existing bus tires primarily employ a three- or four-groove longitudinal tread pattern design, with tread saturation maintained between 68% and 75%. This traditional design has significant drawbacks in practical use: firstly, the center point of the tire crown bears excessive pressure when in contact with the ground, leading to abnormal wear problems such as crown or shoulder wear; secondly, the frequent starting and braking characteristics of electric buses exacerbate stress concentration at the tire bead area, potentially causing bead cracking. These structural defects severely impact tire lifespan and operational economy.

[0004] Therefore, those skilled in the art have provided a wear-resistant electric bus tire with strong grip to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a wear-resistant electric bus tire with strong grip. It adopts a zigzag water wave pattern and arc transition design, combined with an ultra-wide running surface to achieve a tread saturation of over 80%. The inner contour curve is optimized through the balance contour theory, and combined with a low heat generation wear-resistant formula and high-strength skeleton material, it effectively solves the problems of abnormal wear and bead cracking, and significantly improves the tire's load-bearing capacity, wear resistance and service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wear-resistant electric bus tire with strong grip includes a tire body, a central tread groove, a side tread groove, and a connecting groove. The central tread groove and the side tread groove adopt a zigzag water wave pattern design, and the turning points are all transitioned by arcs. The tread saturation reaches more than 80%.

[0008] The side pattern grooves and the middle pattern grooves are connected by a connecting groove to form a continuous groove network, and the saturation of the shoulder pattern reaches more than 43%.

[0009] The above technical solutions employ a zigzag water wave pattern and a rounded transition design, combined with an ultra-wide driving surface to achieve a pattern saturation of over 80%. The inner contour curve is optimized through the balance contour theory, and combined with a low-heat-generating and wear-resistant compound and high-strength skeleton materials, effectively solving the problems of abnormal wear and bead cracks, and significantly improving the tire's load-bearing capacity, wear resistance, and service life.

[0010] Furthermore, all inflection points of the central and side patterned grooves are transitioned by an arc with a radius of 5-15mm;

[0011] The above technical solutions can effectively disperse stress concentration during tire operation, reduce the risk of tearing at the edges of tread blocks, and improve tire wear resistance. At the same time, the rounded transition design can enhance water drainage performance, reduce the risk of slipping on wet roads, and improve the driving safety of buses.

[0012] Furthermore, the tire body adopts an ultra-wide tread design, with the ratio of tread width to tire section width being 0.8-0.85;

[0013] The above technical solutions can increase the contact area between the tire and the ground, improve grip and braking performance, and at the same time, the wide driving surface design can evenly distribute the load, reduce local wear, and extend the tire's service life.

[0014] Furthermore, the width of the connecting groove is 3-8mm and the depth is 5-12mm, extending in a wavy shape to connect the central patterned groove and the side patterned groove;

[0015] The above technical solutions can optimize the tire's drainage path, improve the anti-skid performance on wet roads, reduce hydroplaning, and enhance the tire's heat dissipation capacity, preventing tread aging caused by heat accumulation during high-speed driving, thereby improving the tire's durability and reliability.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes a wear-resistant electric bus tire with strong grip. Through an innovative zigzag water wave pattern design, combined with arc transition treatment, it effectively disperses ground pressure and solves the abnormal wear problems such as crown and shoulder wear of traditional tires. It adopts an ultra-wide driving surface and large contour design, increasing the tread saturation to over 80%, which greatly enhances the tire's load-bearing capacity and wear resistance. Based on the balanced contour theory, the inner contour curve is optimized, making the stress on various parts of the tire more balanced and significantly reducing the risk of bead cracking. Combined with the application of low heat generation wear-resistant compound and ultra-high strength skeleton material, the tire can still maintain excellent durability under frequent start-stop conditions, comprehensively improving the service life and operating economy of electric bus tires.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figure 1-3 This utility model provides a specific implementation method:

[0025] A wear-resistant electric bus tire with strong grip includes a tire body 1, a central tread groove 2, a side tread groove 3 and a connecting groove 4. The central tread groove 2 and the side tread groove 3 adopt a zigzag water wave pattern design, and the turning points are all rounded transitions. The tread saturation reaches more than 80%.

[0026] The side pattern groove 3 and the middle pattern groove 2 form a continuous groove network through the connecting groove 4, and the saturation of the shoulder pattern reaches more than 43%;

[0027] The design features a zigzag water wave pattern with rounded transitions, and an ultra-wide driving surface that achieves a saturation of over 80%. The inner contour curve is optimized through the balance contour theory, and combined with a low-heat-generating and wear-resistant compound and high-strength skeleton materials, it effectively solves the problems of abnormal wear and bead cracks, significantly improving the tire's load-bearing capacity, wear resistance, and service life.

[0028] All inflection points of the center tread groove 2 and sidewall tread groove 3 feature a 5-15mm radius arc transition, effectively dispersing stress concentration during tire operation, reducing the risk of tearing at the tread block edges, and improving tire wear resistance. Simultaneously, the arc transition design enhances drainage performance, reduces the risk of slippage on wet roads, and improves bus driving safety. The tire body 1 features an ultra-wide tread surface design, with a tread surface width to tire section width ratio of 0.8-0.85, increasing the tire's contact area with the ground, improving grip and braking performance. The wide tread surface design also evenly distributes load, reducing localized wear and extending tire life. The connecting groove 4, with a width of 3-8mm and a depth of 5-12mm, extends in a wave shape connecting the center tread groove 2 and sidewall tread groove 3. This optimizes the tire's drainage path, improves anti-skid performance on wet roads, reduces hydroplaning, and enhances heat dissipation, preventing tread aging due to heat buildup during high-speed driving, thereby improving tire durability and reliability.

[0029] Working Principle: Under operating conditions, the tire's zigzag wave-like tread pattern, combined with a 5-15mm radius circular transition, effectively disperses ground pressure, ensuring even stress distribution and avoiding abnormal wear problems common in traditional tires, such as crown and shoulder wear. It also significantly reduces stress concentration at the edges of the tread blocks. The extra-wide tread surface design (width to section width ratio 0.8-0.85) increases the contact area, providing greater friction during frequent starts, stops, and turns of the bus, ensuring driving stability while reducing pressure per unit area. The wave-shaped connecting grooves (3-8mm wide, 5-12mm deep) optimize drainage paths, quickly draining water in wet conditions to prevent hydroplaning and enhancing heat dissipation to prevent tread aging. A tread saturation of over 80% and a shoulder tread saturation of over 43% provide a larger effective contact area while ensuring drainage performance. These design elements work synergistically to maintain excellent grip, wear resistance, and durability under the high-load, frequent start-stop conditions of electric buses, significantly improving operational safety and economy.
