Description

Technical Field

[0002] In recent years, with the development of the economy and the improvement of safety awareness, more and more light truck owners have begun to consciously replace their tires with light truck snow tires in winter to cope with the snow on the roads in winter and improve winter driving safety. The so-called light truck snow tires refer to light truck tires that are suitable for low temperature environments (usually refers to ambient temperatures below 0°) and can drive normally on ice and snow roads. The biggest difference between light truck snow tires and ordinary light truck tires is that they maintain greater grip on soft snow roads, preventing the vehicle from slipping and losing control, and ensuring vehicle safety.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0018] Reference Figure 1A high-performance light truck snow tire includes a center tread block 1, a shoulder tread block 2, a longitudinal groove 3, a transverse groove 4, a center groove 5, a non-through V-shaped groove 6, a zigzag 3D stereoscopic knife groove steel sheet 7, a zigzag 3D stereoscopic knife groove steel sheet 2 8, a groove bottom trapezoidal silencer 9 and a reinforcing rib 10. The center tread block 1 is designed in a diamond shape, the non-through V-shaped groove 6 is located at the front end of the diamond shape, the longitudinal groove 3 is designed between the shoulder tread block 2 and the center tread block 1, the longitudinal groove 3 adopts a zigzag shape design, the zigzag 3D stereoscopic knife groove steel sheet 7 is designed on the shoulder tread block 2, the transverse groove 4 is designed between two adjacent shoulder tread blocks 2, the zigzag 3D stereoscopic knife groove steel sheet 2 8 is designed on the center tread block 1, the groove bottom trapezoidal silencer 9 is designed between two adjacent shoulder tread blocks 2, and the reinforcing rib 10 is designed between two adjacent center tread blocks 1.

[0019] By optimizing the pattern shape, widening the transverse grooves, optimizing the longitudinal and width groove shapes and depths, and adopting zigzag 3D grooved steel sheets and oblique steel sheet designs, the tire's wet noise performance is improved while ensuring snow performance compared to existing tires of the same type and specifications.

[0020] Specifically, in this embodiment, the non-through V-shaped groove 6 has a groove width of 2 to 7 mm, a depth of 6 to 10 mm, and a groove angle of 100 to 160 degrees, which improves the rigidity of the pattern center and the tire grip. The large-angle V-shaped groove drains water and snow more smoothly, improving wet performance.

[0021] Specifically, in this embodiment, the number of the zigzag 3D three-dimensional sipe steel sheets 7 is 2 to 10. The 3D three-dimensional sipe steel sheets are used to balance the pattern rigidity, destroy the water film on the wet road surface, and improve the wet performance.

[0022] Specifically, in this embodiment, the width of the longitudinal groove 3 is 5 to 15 mm and the depth is 4 to 8 mm, which ensures that the tire has excellent grip and braking force on snowy and slippery roads. The widened longitudinal groove (3) can ensure a larger water discharge capacity and stronger wet performance while ensuring the snow discharge function.

[0023] Specifically, in this embodiment, the width of the transverse groove 4 is 4 to 12 mm, and the depth is 2 to 8 mm.

[0024] Specifically, in this embodiment, the zigzag 3D stereoscopic sipe steel sheet 2 8 uses a zigzag 3D stereoscopic sipe steel sheet to balance the rigidity of the pattern blocks, make the pattern softer, increase the pattern contact area, and ensure the handling performance of the vehicle when turning.

[0025] Specifically, in this embodiment, the number of the trapezoidal silencers 9 at the bottom of the groove is 5, the width is 6-10 mm, and the height is 1-2.5 mm, which can reduce the pattern noise generated by the convergence of airflow.

[0026] Specifically, in this embodiment, the reinforcing rib 10 has a width of 12-16 mm and a height of 2-4 mm, and connects the tread blocks, thereby increasing rigidity and improving snow performance.

[0027] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
