Description

Technical Field

[0001] This utility model relates to the field of fuel-saving tire technology, and in particular to a high-durability fuel-saving tire. Background Technology

[0002] In recent years, the rapid construction of my country's expressway network has led to a high-speed increase in the turnover of road freight. In 2020, road transport accounted for 73.8% of the total freight volume of all modes of transport, maintaining its dominant position in the comprehensive transportation system. Road freight is an important industry supporting economic and social development. With countless trucks traveling on the roads every day, tire performance is crucial. Unlike passenger car tires, which prioritize quietness and comfort, truck tires prioritize wear resistance and fuel efficiency to improve economic efficiency.

[0003] In the context of a sluggish economy and increasingly fierce competition in the logistics industry, rising fuel prices are undoubtedly adding insult to injury for logistics companies. As truck drivers increasingly seek tires that are more fuel-efficient, durable, and have lower total cost of ownership (TCO), fuel-efficient tires have become the new favorite in the freight logistics sector. For truck drivers and logistics fleets, choosing fuel-efficient tires during periods of soaring fuel prices means significant savings in fuel consumption, which not only translates to lower costs but also provides a greater competitive advantage in the fierce market.

[0004] Therefore, those skilled in the art have provided a high-durability, fuel-efficient tire 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 high-durability, fuel-efficient tire. By designing a balanced inner profile using finite element software, employing a low rolling resistance compound, improving the rigidity and deformation resistance of the tire crown, reducing tire crown deformation under high loads, enhancing tire durability, and lowering the tire rolling resistance coefficient.

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

[0007] A high-durability, fuel-efficient tire includes a first tire and a second tire, both of which have multiple belt layers inside.

[0008] The first tire includes a first belt layer, and the first tire has a first belt layer, a second belt layer, a third belt layer and a fourth belt layer disposed inside the first tire;

[0009] The second tire includes a fifth belt layer, and the second tire has a fifth belt layer, a sixth belt layer and a seventh belt layer disposed inside it;

[0010] The above technical solution provides a high-durability and fuel-saving tire. By designing a balanced inner contour using finite element software, adopting a low rolling resistance compound, improving the rigidity and deformation resistance of the tire crown, reducing tire crown deformation under high load, improving tire durability, and reducing the rolling resistance coefficient, a high-durability and fuel-saving tire series exclusively for Zhongce is created.

[0011] Furthermore, the first and fifth belt layers are both designated as EA031 B45-33ST, with an angle of 24 degrees and a thickness of 170 mm.

[0012] The above technical solutions improve tire strength.

[0013] Furthermore, the model of the second belt layer and the sixth belt layer are both set to EA031 B45-33ST, the angle is both set to 15 degrees, and the thickness is both set to 210mm;

[0014] The above technical solutions improve tire hardness, stabilize the tread area, suppress deformation at high speeds, and enhance directional stability.

[0015] Furthermore, the third and seventh belt layers are designated as EA032 B40-22HE and EA031 B40-22HE, respectively, and the seventh belt layer has an angle of 15 degrees and a thickness of 110 mm.

[0016] The above technical solution reduces tread creep through rigid constraints, thereby reducing rolling resistance and extending tire life.

[0017] Furthermore, the fourth belt layer is designated as EA031 B40-35HI and its thickness is set to 100mm;

[0018] The above technical solutions maintain tire shape and optimize high-speed performance and handling.

[0019] Furthermore, both the first and second tires are equipped with steel cord fabric inside, the steel cord fabric being model EA031 B45-33ST and consisting of 4 cords wound 31 times.

[0020] The above technical solutions support the internal air pressure, transmit power, and distribute vehicle load. Their rigidity directly affects the tire's impact resistance and shape stability.

[0021] Furthermore, the second tire has three belt layers inside, and the steel cords are arranged in a 0-degree belt layer with completely parallel lines along the tire circumference.

[0022] Through the above technical solution, the steel cords are arranged completely parallel to each other along the tire circumference, directly adhering to the tire body or covering the cross belt layer, forming a rigid clamping effect.

[0023] Furthermore, the first tire and the second tire both have a shoulder width of 216mm, a total width of 316mm and 306mm respectively, a shoulder thickness of 28mm and 27.5mm respectively, and a center thickness of 17mm and 18mm respectively;

[0024] The above technical solutions improve tire strength and durability, thereby extending tire lifespan.

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model proposes a high-durability fuel-saving tire. Without changing the tread pattern, the construction design is adjusted to improve the tire's ground contact rectangle coefficient, making the ground pressure distribution more uniform. Through optimization of construction design such as semi-finished product size, steel component distribution, cord angle, skeleton material strength, and low rolling resistance formula, excellent fuel-saving effect is achieved. Moreover, with the shoulder thickness / crown center thickness in the tire section direction being about 1.3 and the change in groove width before and after inflation being less than 1mm, the ground contact rectangle coefficient is greater than 0.94, thereby achieving the tire's fuel-saving effect.

[0036] A high-durability, fuel-efficient tire includes a first tire 1 and a second tire 2, both of which have multiple belt layers inside.

[0037] The first tire 1 includes a first belt layer 101, and the first tire 1 has a first belt layer 101, a second belt layer 102, a third belt layer 103, and a fourth belt layer 104 disposed inside it.

This provides a high-durability and fuel-saving tire. The balanced inner contour is designed using finite element software, and a low rolling resistance compound is used to improve the rigidity and deformation resistance of the tire crown, reduce tire crown deformation under high load, improve tire durability, and reduce the tire rolling resistance coefficient.

[0038] Reference Figure 3 , Figure 4 and Figure 5The first belt layer 101 and the fifth belt layer 201 are both designated as EA031 B45-33ST, with an angle of 24 degrees and a thickness of 170mm, to improve tire strength. The second belt layer 102 and the sixth belt layer 202 are both designated as EA031 B45-33ST, with an angle of 15 degrees and a thickness of 210mm, to improve tire hardness, stabilize the tread area, suppress deformation at high speeds, and enhance directional stability. The third belt layer 103 and the seventh belt layer 203 are designated as EA032 B40-22HE and EA031 B40-22HE, respectively. The seventh belt layer 203 has an angle of 15 degrees and a thickness of 110mm, which reduces tread creep through rigid constraint and reduces rolling resistance to extend tire life. The fourth belt layer 104 is designated as EA031. The tire is B40-35HI with a thickness of 100mm to maintain tire shape and optimize high-speed performance and handling. Both the first tire 1 and the second tire 2 have steel cords 3 inside. The steel cords 3 are model EA031B45-33ST and consist of 4 cords wound 31 times.

[0039] Working Principle: Finite element analysis (FEM) software is used to analyze the crown deformation of high-end wide-base tires under high load conditions. A relatively balanced crown profile is developed under stress, enhancing crown rigidity and reducing rolling resistance. Excellent fuel-saving effects are achieved through optimization of semi-finished product dimensions, steel component distribution, cord angle, carcass material strength, and low rolling resistance compound. The balanced inner profile designed by FEM software, the use of low rolling resistance compound, and the improvement of crown rigidity and deformation resistance reduce crown deformation under high loads, enhancing tire durability and thus lowering the rolling resistance coefficient. This results in tire outer dimensions conforming to GB / T2977-2016 (mark rectangle coefficient ≥92%), strength conforming to GB / T4501-2016 (strength percentage ≥130%), durability conforming to QZCR A05102-011-2023 (durability time ≥97h), and rolling resistance conforming to ISO 28580-2018 (rolling resistance coefficient <).
