Description

Technical Field

[0001] This utility model relates to the field of tire tread pattern structure, and in particular to a tread pattern structure for an all-steel tubeless radial truck tire. Background Technology

[0002] Tire tread patterns can be categorized into different types based on their intended use. Therefore, tread pattern design is developed based on the actual operating environment of the tire. A new tread pattern requires comprehensive consideration of the actual market usage environment. Tire tread pattern design needs to improve the customer experience of using tire products in terms of driving comfort, noise reduction, traction, and braking, increasing customer comfort while ensuring safety. The main driving routes for tubeless tires on the market are paved roads and above. The main quality defects of these tires are shoulder gaps, crown gaps, and poor wear resistance.

[0003] Patent publication number CN206884613U discloses a tread pattern structure for an all-steel tubeless radial truck tire. The tire tread includes a tread with evenly distributed tread patterns. The tread is composed of nine equal sections, with longitudinal straight grooves evenly distributed in the same direction along the center line of the tread circumferentially to both sides. The groove bottoms employ a transition structure with different slopes, and heat dissipation steel fins are distributed on the tire shoulder. The longitudinal grooves are connected by wavy grooves. This wavy design is typically quite curved, which may result in lower drainage efficiency because water needs to flow along a curved path, easily leaving moisture behind and reducing grip on wet surfaces. Furthermore, the small steel fins in the side grooves are prone to tearing during cornering, affecting tire lifespan. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a tread pattern structure for an all-steel tubeless radial truck tire. This structure has better wear resistance, reduces the probability of premature tire damage caused by shoulder gaps, crown gaps, and poor wear resistance, and also helps to improve drainage efficiency, increase wet grip, and reduce noise.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A tread pattern structure for an all-steel tubeless radial truck tire includes a tire tread, a main straight groove pattern is provided at the center line of the tire tread circumferential direction, and longitudinal straight groove patterns with the same direction are evenly distributed along the center line of the tire tread circumferential direction to both sides, including a first longitudinal straight groove pattern located near the center line area and a second longitudinal straight groove pattern located away from the center line area.

[0007] Adjacent longitudinal straight groove patterns are connected by transverse inclined grooves, including a first transverse inclined straight groove connecting adjacent first longitudinal straight groove patterns, a second transverse inclined straight groove connecting adjacent first longitudinal straight groove patterns and second longitudinal straight groove patterns, and a Z-shaped transverse inclined groove.

[0008] Furthermore, the first longitudinal straight groove pattern has two lines, and the second longitudinal straight groove pattern has two lines.

[0009] Furthermore, the first transverse inclined straight groove and the second transverse inclined straight groove are parallel, and two adjacent first transverse inclined straight grooves and second transverse inclined straight grooves are located on the same straight line.

[0010] Furthermore, the Z-shaped transverse inclined groove is located between two adjacent second transverse inclined straight grooves.

[0011] Furthermore, the spacing of the first transversely inclined straight groove is 40-60 mm, the spacing of the second transversely inclined straight groove is 40-60 mm, and the spacing of the Z-shaped transversely inclined groove is 40-60 mm.

[0012] Furthermore, the first transverse inclined straight groove is 1-1.8 mm wide, 4-5 mm deep, and has an inclination angle of 15°-75°, where the inclination angle represents the angle between the first transverse inclined straight groove and the transverse horizontal line.

[0013] The second transverse inclined straight groove is 1-1.8 mm wide, 4-5 mm deep, and has an inclination angle of 15°-75°.

[0014] The Z-shaped transverse inclined groove is 1-1.8 mm wide, 4-5 mm deep, and has an inclination angle of 15°-75°.

[0015] Furthermore, the Z-shaped transverse inclined groove includes a first transverse section, a vertical section, and a second transverse section connected end to end;

[0016] The first transverse segment and the second transverse segment are parallel to the first transverse inclined straight groove;

[0017] The vertical segment is parallel to the longitudinal straight groove pattern.

[0018] Furthermore, the length ratio of the first horizontal segment, the vertical segment, and the second horizontal segment is 2-3:1:2-3.

[0019] Furthermore, several exhaust holes are distributed around the first transverse inclined straight groove, the second transverse inclined straight groove, and the Z-shaped transverse inclined groove.

[0020] Furthermore, the longitudinal straight groove tread wall is inclined inward at 5° to 25°, which means that the angle between the groove wall and the center line perpendicular to the tire tread is 5° to 25°.

[0021] The bottom of the longitudinal straight groove pattern is wavy along the longitudinal direction, and the inclination angle of the groove wall is different at different longitudinal sections, and the inclination angle of the two groove walls at the same longitudinal section is different.

[0022] Furthermore, the longitudinal straight groove pattern transitions from the tire tread to the groove bottom, and the wavy groove bottom has a transition structure with different slopes.

[0023] Furthermore, the longitudinal straight groove pattern has a groove width of 12-16mm, a groove depth of 15-20mm, and a circular arc transition with a radius of 4-6mm at the bottom.

[0024] The main longitudinal straight groove pattern has a width of 1-1.8 mm and a depth of 4-5 mm.

[0025] Furthermore, the tire tread is composed of nine equal movable sections.

[0026] Furthermore, the tread pitch of the tire is 64 pitches.

[0027] Furthermore, wear indicators are provided on the main straight groove pattern. The preset depth of the wear indicator is 2.4mm. When the tread wear depth reaches this critical threshold, it indicates that the tire has exceeded the legal safe wear limit and the tire needs to be replaced in time to ensure driving safety.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] (1) Tires using the pattern structure of this utility model have high wear resistance and reduce the probability of early tire damage caused by uneven wear, uneven wear and stone trapping.

[0030] (2) The bottom of the straight groove pattern of this utility model is wavy. The longitudinal straight groove pattern transitions from the tire tread to the bottom of the groove. The wavy bottom of the groove has a transition structure with different slopes, which can effectively prevent stone fragments from embedding. At the same time, when the tire rolls, the dynamic stress causes the embedded objects to fall off naturally, thus giving it excellent self-cleaning performance. This structural design achieves the dual optimization of anti-stone embedding and self-cleaning functions through the synergistic effect of geometric shape and kinematics.

[0031] (3) The design of the first and second transverse inclined straight grooves of this utility model can guide water flow more directly, improve drainage efficiency, reduce water film effect, and enhance wetland performance. At the same time, the inclined design may provide better lateral support during turning, improving maneuverability. The Z-type transverse inclined groove combines the advantages of longitudinal and transverse directions, and can cut the water film from both longitudinal and oblique directions at the same time, resulting in higher drainage efficiency. It can also lock snow or mud through the serrated structure, enhancing traction on snow or mud. At the same time, it cuts water flow in multiple directions, reducing noise, and is suitable for high-performance or all-terrain tires.

[0032] (4) The pattern structure of this utility model is novel and beautiful, which caters to customer preferences and has high market acceptance. Attached Figure Description
