Description

Technical Field

[0001] The utility model relates to the technical field of snow radial tires, in particular to a snow radial tire with high wet slip performance. Background Art

[0002] In northern my country, Europe, and parts of Russia, the winter weather is cold, snowfall is heavy, and snow often accumulates on the road. In order to ensure driving safety, it is necessary to use suitable tires to cope with such road conditions. Summer tires have a significantly reduced grip under low temperature conditions due to their tread formula and pattern design, which poses a great safety hazard on icy and snowy roads in winter. In recent years, with the development of the economy and the improvement of safety awareness, more and more car owners have begun to consciously replace their tires with snow tires in winter to cope with the snow on the road in winter and improve winter driving safety.

[0003] At present, many cities will use snow melting agents on the road after snowfall to reduce the snow on the road, which leads to water accumulation on the road surface of urban roads. Most snow tires pay more attention to the safety performance on snowy and icy roads, but ignore the safety of water accumulation on the road surface after the snow melts. Therefore, improvements are needed. Utility Model Content

[0004] The utility model aims to provide a snow radial tire with high wet-slip performance, thereby solving the problem of poor wet-slip performance of existing snow tires.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snow radial tire with high wet skid performance, comprising a center tread block, a second tread block and a shoulder tread block, non-through V-shaped grooves and through V-shaped grooves are commonly arranged between the longitudinally adjacent center tread blocks and the longitudinally adjacent second tread blocks, and the non-through V-shaped grooves and the through V-shaped grooves are connected, an oblique groove is arranged between the center tread block and the second tread block, a longitudinal groove is arranged between the second tread block and the shoulder tread block, and a transverse groove is arranged between two adjacent shoulder tread blocks.

[0006] Preferably, the central pattern block is arrow-shaped, and the through-type V-shaped groove is located at the end of the arrow, and the non-through-type V-shaped groove is located in the middle of the arrow. The design of the non-through-type V-shaped groove can improve the rigidity of the pattern center and improve the tire grip. In addition, the V-shaped angles of the non-through-type V-shaped groove and the through-type V-shaped groove are both large, which makes water and snow discharge smoother and improves wet performance.

[0007] Preferably, the second pattern block is an irregular trapezoid, and the oblique groove is connected to both the non-through V-shaped groove and the through V-shaped groove. The zigzag oblique groove, the non-through V-shaped groove and the through V-shaped groove are connected, which can ensure that the tire has excellent grip and braking force on snowy and slippery roads.

[0008] Preferably, the longitudinal grooves are zigzag-shaped and communicate with the transverse grooves. The zigzag longitudinal grooves can ensure that the tire has excellent grip and braking force on snowy and slippery roads, and the widened longitudinal grooves can ensure greater water discharge and stronger wet performance while ensuring the snow discharge function.

[0009] Preferably, a zigzag 3D three-dimensional sipe steel sheet 1 is embedded in the interior of the central tread block, and a zigzag 3D three-dimensional sipe steel sheet 2 and an oblique steel sheet 1 are embedded in the interior of the second tread block, and the zigzag 3D three-dimensional sipe steel sheet 1, the zigzag 3D three-dimensional sipe steel sheet 2 and the oblique steel sheet 1 are all multiple and made of steel. The zigzag 3D three-dimensional sipe steel sheet 1, the zigzag 3D three-dimensional sipe steel sheet 2 and the oblique steel sheet 1 can balance the pattern rigidity, destroy the water film on the wet road surface, and improve the wet performance.

[0010] Preferably, the shoulder pattern block is embedded with a zigzag 3D three-dimensional sipe steel sheet three and an oblique steel sheet two, and the number of the zigzag 3D three-dimensional sipe steel sheet three and the oblique steel sheet two are both multiple. The zigzag 3D three-dimensional sipe steel sheet three and the oblique steel sheet two also have the function of balancing the pattern rigidity.

[0011] The beneficial effects of the utility model are as follows:

[0012] Compared with existing tires of the same type and specification, the utility model improves the wet performance of the tire and reduces the risk of tire slipping while ensuring snow performance by widening the transverse grooves, optimizing the shape and depth of the longitudinal grooves, and adopting zigzag 3D stereoscopic knife-grooved steel sheets and oblique steel sheet designs.

[0019] The specific implementation process of the utility model is as follows: the central pattern block 1 is designed in an arrow shape, and a through-type V-shaped groove 8 is designed in the front of the arrow, with a groove width of 3mm to 8mm and a depth of 6 to 10mm.
