[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-3 As shown, the radial tire for engineering machinery in this embodiment includes a tire tread 1. A straight tread wall 2 and a U-shaped tread wall 3 are fixedly installed around the tire tread 1. A first reinforcing rib 4 is fixedly installed between the straight tread wall 2 and the U-shaped tread wall 3. Side tread walls 5 are fixedly installed around the tire tread 1 and on both the front and rear sides of the straight tread wall 2. Shoulder tread walls 6 are fixedly installed around the tire tread 1 and on both the front and rear sides of the side tread walls 5. Shoulder grooves 7 are formed on the surface of the shoulder tread wall 6.
[0025] In this embodiment, when the tire is working, by setting up the straight tread wall 2 and the U-shaped tread wall 3 with different shapes, the friction generated in contact with the ground is increased, which can effectively improve the tire's grip, drainage performance and wear resistance. The first reinforcing rib 4 enhances the structural strength between the straight tread wall 2 and the U-shaped tread wall 3 and prevents the tread wall from deforming. The side tread wall 5 and the shoulder tread wall 6 are located at the edge of the tire and assist the main tread wall in enhancing grip. At the same time, the shoulder groove 7 can assist in drainage.
[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the angle between the straight tread wall 2, the U-shaped tread wall 3, the first reinforcing rib 4, the side tread wall 5, the shoulder tread wall 6, and the tread groove wall formed by the tire tread 1 is set to 10° to 20°, and the bottom of the groove adopts a small arc design with a radius of less than 5mm and a central angle greater than 120°. Setting the tread groove wall angle to 10° to 20° ensures that the tire tread groove has sufficient drainage space and can effectively squeeze out water during the tire rolling process, reducing the occurrence of hydroplaning. The small arc design at the bottom of the groove can avoid stress concentration, improve the strength and durability of the bottom of the tread groove, and extend the tire service life.
[0027] In one embodiment, such as Figure 1 and Figure 2As shown, the straight tread wall 2 and the U-shaped tread wall 3 are evenly distributed at the center of the tire tread 1 and alternate with each other. The height of the straight tread wall 2 and the U-shaped tread wall 3 is 15-25mm. The height of the first reinforcing rib 4 is half the height of the straight tread wall 2 and the U-shaped tread wall 3. The even distribution of the straight tread wall 2 and the U-shaped tread wall 3 at the center of the tire tread 1 and their alternation with each other can make the force on the tire more even during rolling, avoiding local wear. The height of the first reinforcing rib 4 is half the height of the straight tread wall 2 and the U-shaped tread wall 3. Without affecting the normal function of the tread, it effectively enhances the connection strength between the tread walls and improves the overall tear resistance of the tire.
[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, a main groove 8 is formed between the straight tread wall 2 and the two connected U-shaped tread walls 3, and an auxiliary groove 9 is formed between the two connected side tread walls 5. A connecting groove 10, which connects to the main groove 8 and the auxiliary groove 9, is provided on the side of the side tread wall 5 closest to the straight tread wall 2. The connecting groove 10 has an inclination angle of 30°-45°, guiding water flow to the auxiliary groove 9. The main groove 8 formed between the straight tread wall 2 and the two connected U-shaped tread walls 3, and the auxiliary groove 9 formed between the two connected side tread walls 5, together constitute the main drainage channels of the tire, greatly improving the tire's drainage capacity. The connecting groove 10 connects the main groove 8 and the auxiliary groove 9, making the drainage path smoother, further enhancing the drainage effect, and reducing the decrease in tire-road friction caused by water accumulation.
[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the side tread wall 5 has a first groove 11 that matches the main groove 8 on the side near the straight tread wall 2. The depth of the first groove 11 is the same as that of the main groove 8, which increases the drainage area of the main groove 8, allowing water to drain out of the main groove 8 more quickly, further optimizing drainage performance and improving tire safety on wet and slippery roads.
[0030] In one embodiment, such as Figure 2 and Figure 3 As shown, a transverse groove 12 is formed between the side tread wall 5 and the shoulder tread wall 6. The transverse groove 12 is connected to the shoulder groove 7 and the auxiliary groove 9, which further enriches the tire's drainage network, enabling the tire to effectively drain water in all directions. At the same time, the transverse groove 12 can also increase the grip of the tire edge and improve the stability of the vehicle when turning or performing other operations.
[0031] In one embodiment, such as Figure 2 and Figure 3As shown, a second reinforcing rib 13 is fixedly installed on the bottom inner side of the transverse groove 12. The front and rear sides of the second reinforcing rib 13 are fixedly connected to the sidewalls of the side tread wall 5 and the shoulder tread wall 6, respectively. The second reinforcing rib 13 fixedly installed on the bottom inner side of the transverse groove 12 enhances the structural strength of the transverse groove 12 and prevents the transverse groove 12 from being damaged when subjected to road impact and tire deformation. The front and rear sides of the second reinforcing rib 13 are fixedly connected to the sidewalls of the side tread wall 5 and the shoulder tread wall 6, respectively, further improving the overall structural stability of the tire edge.
[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, a second groove 14 is provided on the surface of the second reinforcing rib 13 near the center. Anti-slip grooves are provided on the surfaces of the straight patterned wall 2, the U-shaped patterned wall 3, the side patterned wall 5 and the shoulder patterned wall 6, which can further enhance the drainage capacity and allow accumulated water to be discharged better through the transverse groove 12.
[0033] The above embodiment discloses a radial tire for engineering machinery. By setting different shaped straight tread walls 2 and U-shaped tread walls 3, the friction generated in contact with the ground is increased, effectively improving the tire's grip, water drainage performance, and wear resistance. The first reinforcing rib 4 enhances the structural strength between the straight tread walls 2 and U-shaped tread walls 3, preventing tread wall deformation. The side tread walls 5 and shoulder tread walls 6, located at the tire edge, assist the main tread wall in enhancing grip. The straight tread walls 2 and U-shaped tread walls 3 are evenly distributed in the center of the tire tread 1 and alternate with each other, making the force on the tire more even during rolling and avoiding localized wear. The first reinforcing rib 4... The height of rib 4 is half the height of the straight tread wall 2 and the U-shaped tread wall 3. Without affecting the normal function of the tread, it effectively enhances the connection strength between the tread walls and improves the overall tear resistance of the tire. Together with the second reinforcing rib 13, which is fixedly connected to the side tread wall 5 and the shoulder tread wall 6, it further improves the overall structural stability of the tire edge. At the same time, the main groove 8 formed between the straight tread wall 2 and the two connected U-shaped tread walls 3, and the auxiliary groove 9 formed between the two connected side tread walls 5, together with the connecting groove 10, the transverse groove 12 and the shoulder groove 7, constitute the tire's drainage channel, which greatly improves the tire's drainage capacity.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
