Description

Technical Field

[0001] The utility model relates to the technical field of tire design, in particular to a tread pattern structure of an all-steel load-bearing tubeless radial tire. Background Art

[0002] Tires are donut-shaped elastic rubber products used for ground contact and rolling, which are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures when driving, so they must have high load-bearing performance, traction performance and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used in tire production, which shows the ability of tires to consume rubber.

[0003] There are many different designs of tire treads. Their designs are based on the suitability for different purposes and road conditions. These aspects should also be considered when selecting tires. Tire treads play a very important role in the entire driving process. A well-designed tread can not only effectively save fuel, but also reduce the noise generated by the car during driving. At the same time, it can enhance the driving force, braking force and traction performance of the car on various harsh and slippery roads, thereby improving the safety of car driving.

[0004] There are generally several types of tire patterns:

[0005] (1) Straight groove pattern, also called ordinary pattern, is a pattern design with longitudinal grooves as the main feature.

[0006] Features: excellent operating stability, small rotation resistance, low noise, especially excellent drainage performance, not easy to slip laterally.

[0007] Applicable: vehicles used on flat roads: cars, trucks, and even airplanes.

[0008] Disadvantages: Poor drive and traction.

[0009] (2) Horizontal groove pattern: A pattern design with horizontal grooves as the main feature.

[0010] Features: The driving force, braking force and traction of the transverse groove pattern are particularly excellent, and its wear resistance is excellent.

[0011] Applicable: gravel roads and other harsh road conditions Vehicle type: mostly used in industrial and medium and short-distance vehicles such as bulldozers, excavators, loaders and other medium and heavy-duty trucks.

[0012] Disadvantages: loud noise.

[0013] (3) Vertical and horizontal groove pattern: Vertical and horizontal groove pattern is also called comprehensive pattern, which combines the design of straight groove type and horizontal groove type.

[0014] Features: It combines the advantages of both longitudinal and transverse groove patterns.

[0015] Applicable: bad road conditions.

[0016] Disadvantages: prone to abnormal wear.

[0017] (4) Block pattern: The pattern is arranged regularly in blocks.

[0018] Features: Good driving force and braking force, providing power to drive the car forward.

[0019] Applicable to: snowy, muddy and other roads.

[0020] Disadvantages: poor wear resistance and short mileage life.

[0021] The main light-duty radial tires on the market are driven on roads above paved roads. The main quality defects of tires are shoulder hollow, crown hollow and poor wear resistance. The tires have high requirements for tread patterns, low heat generation, good wear resistance, low noise, low rolling resistance, and novel appearance. Utility Model Content

The tire using the pattern of the utility model reduces the probability of early damage to the tire caused by shoulder hollows, crown hollows and non-wear resistance.
