Description
Technical Field
[0001] The utility model belongs to the technical field of tire design, in particular to a tread pattern structure of an all-steel load-bearing tubeless radial tire and a tire. Background Art
[0002] Tires are donut-shaped elastic rubber products used on various vehicles and machinery for grounded rolling. Typically mounted on metal rims, they support the vehicle's body, cushion external impacts, maintain contact with the road, and ensure vehicle performance. Tires often operate under complex and demanding conditions, enduring deformation, loads, forces, and high and low temperatures. Therefore, they must possess high load-bearing, traction, and cushioning properties. They must also possess high wear and flex resistance, as well as low rolling resistance and heat buildup. Half of the world's rubber consumption is used in tire production, demonstrating the sheer volume of rubber consumed by tires.
[0003] Tire tread designs vary widely, each designed based on suitability for different uses and road conditions. These factors should also be considered when selecting a tire. Tire tread patterns play a crucial role in driving. A well-designed tread not only effectively saves fuel but also reduces noise while driving. It also enhances driving force, braking force, and traction on harsh and slippery roads, thereby improving driving safety.
[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, low rotation resistance, low noise, especially excellent drainage performance, not easy to slip laterally.
[0007] Applicable to: 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 transverse groove pattern has excellent driving force, braking force and traction, and its wear resistance is excellent.
[0011] Applicable to: gravel roads and other harsh road conditions. Vehicle types: mostly used in industrial 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 is a combination of straight groove and horizontal groove pattern design.
[0014] Features: It combines the advantages of both longitudinal and transverse groove patterns.
[0015] Applicable to: 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 driving routes of tubeless tires on the market are roads above paved roads. The main quality defects of tires are shoulder hollow, crown hollow and poor wear resistance. Tires have high requirements for tread patterns and should have good wear resistance and novel appearance.
[0022] For example, CN111703258A discloses a tread structure and a tire, wherein the tread structure comprises outer shoulder ribs, center ribs, and inner shoulder ribs separated by longitudinal main grooves, arranged in sequence from the outer side to the inner side; the outer shoulder ribs are provided with a plurality of first transverse grooves arranged circumferentially and axially with unequal pitches; the inner shoulder ribs are provided with a plurality of second transverse grooves arranged circumferentially and axially with unequal pitches; the first transverse grooves penetrate the longitudinal main grooves; the second transverse grooves axially penetrate the inner shoulder ribs; the pitch of the first transverse grooves is greater than the pitch of the second transverse grooves; the groove width of the first transverse grooves is less than the groove width of the second transverse grooves; the center ribs are provided with a plurality of first sipes of unequal spacing; the first sipes are arranged axially and tilted, and at least one end penetrates the adjacent longitudinal main grooves. However, this application only discloses that the transverse groove pattern has poor design guidance, poor drainage, and poor grip. Utility Model Content

[0074] The above embodiments may be implemented individually or in any combination of two or more.
[0075] The above implementation is described in more detail below with reference to specific examples.
[0076] Example 1
[0077] Tubeless tires have high requirements for road driving. Common tire quality defects include shoulder hollows, crown hollows, and poor wear resistance. Therefore, the tire has high requirements for the tread pattern, which should have good wear resistance and a novel appearance. However, straight groove patterns, transverse groove patterns, longitudinal and transverse groove patterns, and block patterns cannot simultaneously provide good guidance, drainage, grip, puncture resistance, and side slip resistance. In addition, the tire's traction or lateral force is not high. Based on this, this embodiment provides a tread pattern structure for an all-steel load-bearing tubeless radial tire. For its structure, please refer to Figure 1 As shown, it includes a first longitudinal groove 1, a second longitudinal groove 2, a longitudinal and transverse pattern portion 3, and a shoulder block portion 4. The first longitudinal groove 1 is arranged in the center of the crown and distributed along the circumference of the tire tread. The bottom surface of the first longitudinal groove 1 with a circular arc transition extends radially outward to the tread surface to form a groove with gradually increasing width. The second longitudinal groove 2 is evenly arranged on both sides of the first longitudinal groove 1 and distributed along the circumference of the tire tread. The bottom surface of the second longitudinal groove 2 with a circular arc transition extends radially outward to the tread surface to form a groove with gradually increasing width. The longitudinal and transverse pattern portion 3 is between the first longitudinal groove 1 and the second longitudinal groove 2 and is distributed along the tire tread. The circumferential distribution of the tread is used to improve driving performance. The shoulder block 4 is arranged on the outside of the second longitudinal groove 2 and is used to improve drainage performance. The first longitudinal groove 1 is straight, the second longitudinal groove 2 is straight, and a circumferential stone removal groove 201 is arranged in the middle of the second longitudinal groove 2 to improve the stone removal and drainage performance of the tire. A number of exhaust holes 5 are distributed on the first longitudinal groove 1, the second longitudinal groove 2, the longitudinal and transverse pattern parts 3, and the shoulder block 4 to facilitate exhaust during vulcanization, prevent air pockets from causing rounded corners of the pattern and lack of rubber on the sidewall, promote rubber flow, and make the rubber vulcanization more uniform. Indicator arrows 6 are distributed on the side of the tire tread to facilitate confirmation of direction when installing the tire.
[0078] Specifically, the longitudinal and transverse pattern portion 3 includes a third longitudinal groove 301 and a first wavy pattern 302. The third longitudinal groove 301 is arranged in the middle of the first longitudinal groove 1 and the second longitudinal groove 2. The first wavy pattern 302 extends from the outer wall of the second longitudinal groove 2 to the first longitudinal groove 1 and is an S-shaped first wavy pattern 302. The width of the first wavy pattern 302 gradually decreases in the direction from the second longitudinal groove 2 to the first longitudinal groove 1. The third longitudinal groove 301 and the first wavy pattern 302 are staggered to form independent pattern blocks. Such pattern blocks increase the driving performance of the tread. The third longitudinal groove 301 is wavy. The wavy design strengthens the irregularity of the pattern blocks formed by the staggered third longitudinal groove 301 and the first wavy pattern 302, increases friction, and further increases the driving performance of the tread.
[0079] Specifically, the shoulder block portion 4 includes a shoulder block 401 and a second wavy pattern 402. The shoulder blocks 401 are distributed along the circumference of the tire tread at different pitches. The second wavy pattern 402 is arranged on the shoulder block 401 and its extension line intersects with the first longitudinal groove 1. In this embodiment, see Figure 2 As shown, A, B, and C are respectively one pitch, with a total of 3 types, a total of 79 sections, and a running surface width of 234mm. The unequal pitch design reduces the noise generated during high-speed operation of the tire and improves the driving experience. The deep pattern design makes the wear life long and the tire body durability excellent.
[0080] Specifically, the first longitudinal groove 1 has a width of 4 mm and a depth of 20.5 mm, and the groove bottom is a semicircular arc transition with a radius of 1.6 mm. The third longitudinal groove 301 has a depth of 17 mm, the first wavy pattern 302 has a depth of 17 mm, the circumferential stone removal groove 201 has a height of 2.5 mm and a width of 2.5 mm, and the exhaust hole 5 has a diameter of 0.8 mm.
[0081] The working principle of this embodiment is as follows:
[0082] In this embodiment, the third longitudinal groove 301 and the first wavy pattern 302 are staggered to form independent pattern blocks. The third longitudinal groove 301 and the first wavy pattern 302 are staggered to form independent pattern blocks, and an asymmetric pattern is formed along the first longitudinal groove 1, so that the tread rigidity is crossed, and the left and right shapes are like a "self-locking" function, which improves the straight-line driving stability of the vehicle on various road surfaces, has excellent drainage and snow removal performance, enhances the stability of driving on harsh ground, such as snow and water accumulated ground, and takes into account the driving function on normal roads. The third longitudinal groove 301 is wavy, and the wavy design strengthens the irregularity of the pattern blocks formed by the staggered third longitudinal groove 301 and the first wavy pattern 302, increases friction, and further increases the driving performance of the tread. The shoulder block 401 is designed with unequal pitches, which reduces the noise generated during high-speed operation of the tire and improves the driving experience. The deep pattern design makes the wear life long and the tire body durability excellent. A circumferential stone removal groove 201 is arranged in the middle of the second longitudinal groove 2 to improve the tire's stone and water removal performance. Vent holes 5 are distributed on the tread to facilitate exhaust during vulcanization, preventing air pockets that lead to rounded corners and rubber loss on the sidewalls. This promotes rubber flow and ensures more uniform vulcanization. Indicator arrows 6 are distributed on the side of the tire tread to facilitate direction confirmation during tire assembly.

[0085] tire carcass; and
[0086] A tread pattern structure of an all-steel load-bearing tubeless radial tire is provided on the tread of the tire carcass and is as described in Example 1.
[0087] Comparative Example 1
[0088] Compared with Example 1, most of them are the same, except that the first wavy pattern 302 on one side extends from the outer wall of the second longitudinal groove 2 to the first longitudinal groove 1, and the first wavy pattern 302 on the other side extends from the outer wall of the first longitudinal groove 1 to the second longitudinal groove 2, forming a symmetrical arrangement.
[0089] The rolling resistance and grip of Example 1 and Comparative Example 1 were tested using ECE R117, and the test results are shown below:
[0090] performance Example 1 Comparative Example 1 Rolling resistance N / KN 5.898 6.096 Wet road grip performance index G 1.15 1.08
