Description

Technical Field

[0001] The utility model relates to the technical field of mining tires, in particular to a mining tire with an ultra-deepened pattern. Background Art

[0002] The rapid development of infrastructure projects in mining, water conservancy, and transportation has led to an increase in demand for OTR tires. Coupled with recent increases in export volumes, this has created a significant market opportunity for OTR tires. Compared to traditional tires, ultra-deep tread tires offer higher load capacity, heat resistance, wear resistance, and puncture resistance. Harsh working environments place even greater demands on tire performance, leading to market demand for products with enhanced wear and puncture resistance and a longer service life.

[0003] When tires are overloaded for a long time, due to the deep tread pattern, they are prone to problems such as block loss, uneven wear, partial wear, and delamination due to heat generation, which will affect the service life of the tires.

[0004] Based on this, a super-deep pattern mining tire is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, Figure 1-Figure 3 As shown, an ultra-deep pattern mining tire includes a tread block assembly arranged on the tire tread;

[0026] The tread block assembly includes a crown left tread block 1 and a crown right tread block 3 symmetrically arranged from left to right. The crown left tread block 1 and the crown right tread block 3 are both boot-shaped and irregularly change from narrow to wide from the shoulder to the crown. A plurality of longitudinal grooves 4 are arranged between the crown left tread block 1 and the crown right tread block 3 in the direction of travel. A plurality of stone-repelling bosses 6 are arranged inside each of the longitudinal grooves 4. A plurality of transverse groove groups 2 are arranged between the crown left tread block 1 and the crown right tread block 3 in the direction of the tire cross-section width. The transverse groove groups 2 are all arranged in an L-shape.

[0027] In this embodiment, the crown left pattern block 1 and the crown right pattern block 3 effectively increase the contact area between the tire and the ground while ensuring uniform force between the tread and the ground, thereby improving the driving performance and service life of the tire;

[0028] In one embodiment, Figure 1 As shown, in an optional scheme: the transverse groove group 2 includes a first crown groove 21, a second middle groove 22 and a third shoulder groove 23, and the first crown groove 21, the second middle groove 22 and the third shoulder groove 23 are continuously opened in sequence from the center of the crown along the width direction of the tire running surface, and the width along the tire running surface direction gradually widens from the middle of the tire to the shoulder of the tire, so as to facilitate the cleaning of coal slag in the tire grooves.

[0029] In one embodiment, Figure 1As shown, the ratio of the shoulder pattern block width L4 to the shoulder pattern groove width L5 of the crown left pattern block 1 and the crown right pattern block 3 is 1.4-1.5, which is convenient for increasing the contact area between the tire and the ground.

[0030] In one embodiment, Figure 1 As shown, a reinforcing rib 5 is provided at the shoulder edge of the tire near the crown left pattern block 1 and the crown right pattern block 3. The ratio of the height of the reinforcing rib 5 to the pattern depth H2 of the crown left pattern block 1 and the crown right pattern block 3 is 0.1-0.15, which is more conducive to the release of stress in the shoulder pattern blocks while ensuring the heat dissipation of the tire, and at the same time improves the traction of the pattern blocks.

[0031] In one embodiment, Figure 2 As shown, the pattern saturation of the crown left pattern block 1 and the crown right pattern block 3 is 55%-65%, and the angle a between the crown left pattern block 1 and the tire driving direction is 45°-60° to ensure the friction between the tire and the ground.

[0032] In one embodiment, Figure 1 As shown, the width of the transverse groove group 2 and the longitudinal groove 4 gradually widens from the crown center to the shoulder edge, and the ratio of the width L4 of the crown left pattern block 1 and the crown right pattern block 3 to the width L5 of the third shoulder groove 23 is 1.4-1.5.

[0033] In one embodiment, Figure 3 As shown, the number of stone-repelling bosses 6 arranged on the inner side of each longitudinal groove 4 is 2-4, the height H1 of the stone-repelling boss 6 is 0.14-0.16 of the depth H2 of the longitudinal groove 4, and the width L6 of the stone-repelling boss 6 is 0.7-0.8 of the groove bottom width L7 of the longitudinal groove 4.

[0034] In one embodiment, Figure 1 As shown, the ratio of the first lateral distance L1 of the upper end of the crown right pattern block 3 to the distance L3 of 1 / 2 of the tire running surface is 0.1-0.25, and the ratio of the second lateral distance L2 of the upper end of the crown right pattern block 3 to the distance L3 of 1 / 2 of the tire running surface is 0.45-0.55.

[0035] The above embodiment discloses a mining tire with an ultra-deep tread pattern, wherein the inner side of the longitudinal groove 4 is provided with a plurality of stone-repelling bosses 6. Along the tire's running direction, the grooves formed between adjacent left crown blocks 1 and symmetrically distributed right crown blocks 3 are continuous S-shaped longitudinal grooves 4. Along the tire's cross-sectional width, adjacent left crown blocks 1 form a group of gradually changing L-shaped transverse grooves 2. The transverse groove group 2 extends from the center of the crown along the tire's running surface width, encompassing a first crown groove 21, a second middle groove 22, and a third shoulder groove 23. The transverse groove group 2 gradually widens from the center of the tire toward the shoulder. As an ultra-deep tread pattern, the ratio of the shoulder block width L4 of the right crown block 3 to the width L5 of the third shoulder groove 23 is 1.4-1.5. This, combined with the heat dissipation design, enhances handling and extends the tire's service life.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
