Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a radial tire. Background Technology

[0002] With the development of the tire industry, the application of heavy-duty radial tires is becoming increasingly widespread. Radial tires have various tread patterns, including straight groove patterns, lateral groove patterns, block patterns, and mixed patterns.

[0003] Among them, block patterns are often used for short- to medium-distance drive wheel positions, and generally only include lateral pattern blocks, lateral pattern grooves, and longitudinal pattern grooves used to divide the lateral pattern blocks.

[0004] When tires are driven on complex road conditions, blocky tread patterns are prone to problems such as stones getting stuck in the tread grooves, chipping and breaking off, and tire crown bursting. To ensure good tire performance, the tread pattern design requires high standards and must have good resistance to punctures, chipping and breaking off, and cutting.

[0005] In addition, existing radial tires also have problems such as high rolling resistance, poor lateral stability, and easy damage to the tire sidewall. These problems are more prominent under heavy loads, affecting the tire's service life and the vehicle's driving performance. Therefore, a radial tire is proposed. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a radial tire to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a radial tire, comprising:

[0008] The pitch includes a pattern block group, which includes a first pattern block, a second pattern block, a third pattern block, a fourth pattern block, a fifth pattern block, a sixth pattern block, a seventh pattern block, an eighth pattern block, a ninth pattern block, and a tenth pattern block.

[0009] The pattern groove group includes a first pattern groove, a second pattern groove, a third pattern groove, a fourth pattern groove, a fifth pattern groove, and a sixth pattern groove. The pattern groove group is disposed between the intervals of the pattern block group, and the pattern groove groups are interconnected.

[0010] A boss assembly is disposed at the bottom of the groove of the patterned block assembly, and the boss assembly includes a first groove bottom boss, a second groove bottom boss, and a third groove bottom boss.

[0011] A steel sheet assembly, disposed inside the patterned block assembly, includes 3D steel sheet a, 3D steel sheet b, 3D steel sheet c, 3D steel sheet d, and 3D steel sheet e.

[0012] Preferably, the depth of the first, second, third, fourth, fifth, and sixth patterned grooves is 9–17 mm, and the sidewall angle is 0–15°.

[0013] Preferably, the first trench bottom protrusion consists of two layers, with a layer height of 0.5 to 3 mm and a combined height of 1 to 6 mm;

[0014] The second trench bottom protrusion consists of two to three layers, with a layer height of 0.5 to 3 mm and a combined height of 1 to 9 mm;

[0015] The third trench bottom protrusion is composed of a single layer with a height of 0.5 to 3 mm.

[0016] Preferably, the depth of the 3D steel sheets a, b, c, d, and e is 60% to 100% of the pattern depth of the groove group.

[0017] Preferably, the number of steel sheet groups in the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, and tenth patterned blocks is one to four.

[0018] Preferably, the angles between the 3D steel sheet a, 3D steel sheet b, 3D steel sheet c, 3D steel sheet d and 3D steel sheet e and the direction of travel are 0° to 45°.

[0019] Compared with the prior art, the present invention provides a radial tire with the following advantages:

[0020] This utility model achieves effective discharge and dispersion of foreign objects in the tread grooves by setting interconnected tread groove groups at intervals in the tread block groups, in conjunction with the protrusion groups at the bottom of the grooves, reducing the phenomenon of stones being trapped in the tread grooves, enhancing the tire's resistance to punctures, chipping and breaking, and cutting, and solving the problem of damage that is prone to occur in block treads under complex road conditions.

[0021] By incorporating 3D steel sheet groups within the tread block group, the tire's structural strength is enhanced, while the stress distribution is optimized, resulting in reduced rolling resistance and improved lateral stability. This also mitigates the vulnerability of the tire sidewall and ensures tire lifespan and vehicle performance even under heavy loads. Attached Figure Description
