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 dominated by horizontal grooves.

[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 types: 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

In addition, the constantly changing groove angle improves the traction and lateral force of the tire. The longitudinal pattern and the transverse pattern are designed to match the tire to achieve good guidance, drainage, grip and anti-skid performance at high speed. In addition, the constantly changing groove angle improves the traction and lateral force of the tire. The utility model has the advantages of having good wear resistance, reducing abnormal wear, ensuring uniform wear, and reducing the probability of early damage to the tire caused by shoulder empty, crown empty and non-wear resistance. The pattern is arranged regularly, so it fails to effectively reduce the noise generated by the tire during driving.

[0023] The purpose of the utility model can be achieved through the following technical solutions:

[0024] The utility model aims to provide a tread pattern structure of a full-steel load-bearing tubeless radial tire, comprising a tire tread and transverse patterns and longitudinal patterns arranged on the tire tread; the tire tread is composed of ten equal parts of an active mold, and there are four parallel straight grooves on the tire tread; pattern blocks are arranged between adjacent straight grooves, and three pattern blocks are formed between the four parallel straight grooves; the straight grooves include main groove walls and main groove bottoms connected to the main groove walls; the main groove bottoms are S-shaped variable groove bottoms; each pattern block is provided with a staggered design of transverse streamline shallow grooves and longitudinal streamline shallow grooves, the groove bottom adopts a full arc transition design, and a thermometer-shaped heat dissipation shoulder groove is distributed on the shoulder of the tire, which improves the heat dissipation of the shoulder and has a functional warning effect, thereby avoiding symptoms caused by heat generation problems in the shoulder.

[0025] Furthermore, the tire tread pattern pitch is 67 sections, and is evenly distributed in the direction from the ten equal parts of the active mold to the upper and lower side plates, and the block pattern blocks are arranged in the same direction.

[0040] Furthermore, the longitudinal pattern includes longitudinal curved grooves, specifically first longitudinal curved grooves, second longitudinal curved grooves, and straight grooves.

[0041] Furthermore, a plurality of tread exhaust holes penetrating the mold are distributed around each transverse pattern and longitudinal pattern of the tire tread. The center of the tread exhaust hole is 2 mm away from the edge of the pattern (the pattern refers to the transverse pattern or longitudinal pattern corresponding to the tread exhaust hole), and the hole diameter is 0.8 mm. A plurality of exhaust holes penetrating the mold are distributed around each transverse pattern and longitudinal pattern to facilitate exhaust during vulcanization, prevent air pockets from causing rounded corners of the pattern and lack of rubber on the sidewall, promote the flow of rubber, and make the rubber vulcanization more uniform.
