[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. Unless otherwise specified, the methods used in this utility model are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0032] Depend on Figure 1 , Figure 2 As shown, this utility model provides a tire tread pattern, including:
[0033] Central tread block 1 is located at point 8 on the center line of the tread.
[0034] The central patterned block 2 is located on both sides of the central patterned block 1;
[0035] Shoulder tread block 3 is located on the outer side of the middle tread block 2;
[0036] The first longitudinal pattern groove 4 is located between the central pattern block 1 and the middle pattern block 2;
[0037] The second longitudinal tread groove 5 is located between the middle tread block 2 and the shoulder tread block 3;
[0038] Tire tread patterns also include:
[0039] The central transverse tread groove 9 is transversely arranged on the central tread block 2 and is spaced out in several places around the tire circumference. The central transverse tread groove is connected to the first longitudinal tread groove 4 and the second longitudinal tread groove 5 located on the same side. During tire operation, mud or snow water located in the middle of the tread can be discharged through the central transverse tread groove 9 and the second longitudinal tread groove 5, which increases the drainage and soil discharge performance and improves the anti-skid performance.
[0040] In some embodiments, the depth of the first longitudinal tread groove 4 is preferably half the depth of the second longitudinal tread groove 5. Typically, the width of the first longitudinal tread groove 4 is set to 7-15 mm, which can reduce the heat generated during tire driving and improve heat dissipation performance.
[0041] In some embodiments, the width of the first longitudinal patterned groove 4 is preferably 1 / 4 of the width of the second longitudinal patterned groove 5 to increase drainage and soil removal performance.
[0042] In some embodiments, the bottom of the first longitudinal groove 4 and the second longitudinal groove 5 is preferably designed with a rounded bottom to avoid cracks at the bottom of the groove and to make it more resistant to punctures.
[0043] In some embodiments, the present invention further includes lateral shoulder grooves 6, which are laterally arranged through the shoulder tread block 3 and spaced apart in the circumferential direction of the tire; these grooves increase the contact area between the tire tread and the road surface, and help the tire maintain a stable temperature after long-term driving, reduce shoulder heat generation, and improve tire lifespan. The inner end of the lateral shoulder grooves 6 is connected to the second longitudinal groove 5 located on the same side, effectively draining water from the tire and the road surface, reducing the formation of a water film, avoiding the danger of the vehicle "floating on water," and improving driving safety.
[0044] In some embodiments, the present invention also includes a small shoulder groove 11, the inner end of which is connected to a transverse small shoulder groove 6 located on the same side, thereby increasing the heat dissipation area, reducing shoulder heat generation, and improving tire service life.
[0045] In some embodiments, the present invention further includes a large lateral tread groove 7 on the shoulder and a large tread groove 12 on the underside of the shoulder, which are arranged laterally within the tread block 3 and spaced apart in the circumferential direction of the tire; the inner end of the large tread groove 12 on the underside of the shoulder is connected to the large lateral tread groove 7 on the same side of the shoulder, thereby increasing the heat dissipation area, reducing heat generation in the shoulder, and improving the service life of the tire.
[0046] In some embodiments, the width of the large lateral tread groove 7 on the tire shoulder is preferably 1 / 3 of the width of the adjacent tire shoulder tread block 3 on the same side, and the depth is 2-4 mm, which further increases the heat dissipation of the tire shoulder. The shallow depth is intended to avoid the decrease in the support performance of the tire shoulder area caused by the large depth.
[0047] In some embodiments, preferably, the central tread block 1 has a continuously bent strip structure in the circumferential direction of the tire, and its inclination angle α relative to the width direction 10 of the tire tread is 75-85°, which increases the tire's adhesion, that is, grip, and ensures that the vehicle drives stably and does not deviate from the driving direction. Especially on rough and uneven roads, it allows the vehicle to better grip the ground when turning, accelerating, and braking, and can also prevent the tire from slipping between the tire and the road surface in rainy or muddy conditions.
[0048] In some embodiments, preferably, the inclination angle β of the lateral small tread grooves 6 on the tire shoulder relative to the width direction 10 of the tire tread is 5 to 10°, which improves the traction between the tire and the road surface.
[0049] In some embodiments, preferably, the inclination angle γ of the large shoulder groove 12 relative to the width direction 10 of the tire tread is 8 to 15°, which ensures the support performance of the tire shoulder and helps maintain the heat dissipation of the tire during driving.
[0050] Depend on Figure 2 As shown, an agricultural machinery tire has a tire tread pattern as described in any of the above-mentioned items.
[0051] When agricultural machinery tires equipped with the tire tread pattern of this utility model are driven on farmland or mountain roads, the center tread block 1, the middle tread blocks 2 on the left and right sides, and the first longitudinal tread grooves 4 on the left and right sides form a whole, reducing the movement of the tread blocks, ensuring the stability of the vehicle, and increasing the wear resistance of the tread.
