Technical Field

[0001] The utility model relates to the technical field of snow tires, in particular to a snow tire with a radial step structure pattern. Background Art

[0002] Snow tires are tires specially designed for driving on snow or ice. They usually use special tread patterns and rubber formulas to provide better grip and handling performance. The tread pattern of snow tires usually has deeper grooves and raised shoulders, which helps to provide better traction on snow or ice and reduce the risk of slipping. For example, the utility model patent with announcement number CN211808858U discloses a snow tire, which includes a carcass, and the surface of the carcass is provided with a plurality of anti-skid components, and the anti-skid components include a first anti-slip block, a second anti-slip block and a third anti-slip block, and the first anti-slip block, the second anti-slip block and the third anti-slip block are fixedly connected to the tread of the carcass, and are sequentially along the direction from the tire shoulder to the carcass equatorial plane.

[0003] However, in order to increase the grip, the existing snow tires will adopt the method of adding anti-sliding blocks, but the contact area with the ground is correspondingly reduced, and it is still easy to slip when encountering some icy surfaces. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The utility model aims to provide a snow tire with a radial step structure pattern, which solves the problem that in order to increase the grip of existing snow tires, an anti-sliding block is added, but the contact area with the ground is correspondingly reduced, and the tire is still prone to slipping when encountering some icy surfaces.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a snow tire with a radial step structure pattern, including a tire tread, the surface of the tire tread is provided with a linear radial groove one, a linear radial groove two, a linear radial groove three, a linear radial groove four, a linear radial groove five, and a linear radial groove six, the linear radial groove one, the linear radial groove two and the linear radial groove three are on the same side, the linear radial groove four, the linear radial groove five and the linear radial groove six are on the same side, and the linear radial groove one, the linear radial groove two and the linear radial groove three are staggered and symmetrically distributed with the linear radial groove four, the linear radial groove five and the linear radial groove six. The linear radial groove one, the linear radial groove two and the linear radial groove three constitute the left side of the tire pattern, while the linear radial groove four, the linear radial groove five and the linear radial groove six constitute the other side of the tire pattern. A plurality of inverted figure-eight patterns are formed between the patterns on both sides, and are in a radial stepped combination.

[0006] Preferably, the tire tread is embedded with corrugated steel sheet 1 and corrugated steel sheet 2, and the corrugated steel sheet 1 and the linear radial groove 1, linear radial groove 2 and linear radial groove 3 are all arranged to be transversely interlaced, and the corrugated steel sheet 2 and the linear radial groove 4, linear radial groove 5 and linear radial groove 6 are all arranged to be transversely interlaced.

[0007] Preferably, the corrugated steel sheet 1 is a transverse straight steel sheet and is evenly distributed across the width of the tire tread pattern block. By using the corrugated steel sheet 1 as a transverse straight steel sheet, the side of the straight radial groove 1, the straight radial groove 2 and the straight radial groove 3 can be made higher than the other side of the tire.

The linear radial groove 1, the linear radial groove 2, and the linear radial groove 3 are on the same side, and the linear radial groove 4, the linear radial groove 5, and the linear radial groove 6 are on the same side, and the linear radial groove 1, the linear radial groove 2, and the linear radial groove 3 are symmetrically distributed with the linear radial groove 4, the linear radial groove 5, and the linear radial groove 6. The linear radial groove 1, the linear radial groove 2 and the linear radial groove 3 form the left side of the tire pattern, while the linear radial groove 4, the linear radial groove 5 and the linear radial groove 6 form the other side of the tire pattern. A plurality of inverted figure-eight patterns are formed between the patterns on both sides, and are in a radial stepped combination.

[0020] See also Figure 4-5The tread of the tire is embedded with corrugated steel sheet 1 7 and corrugated steel sheet 2 8, and the corrugated steel sheet 1 7 and the linear radial groove 1 1, the linear radial groove 2 2 and the linear radial groove 3 3 are all arranged to be transversely interlaced, and the corrugated steel sheet 2 8 and the linear radial groove 4 4, the linear radial groove 5 5 and the linear radial groove 6 6 are all arranged to be transversely interlaced. The corrugated steel sheet 1 7 and the corrugated steel sheet 2 8 are arranged to be transversely interlaced, and combined with the existing pattern, the performance frequency generated by the pattern and the air can be reduced, so as to achieve the effect of reducing noise, making the driver and passengers quieter and more comfortable.

[0021] See also Figure 4-5 , the wave steel sheet 1 7 is a transverse straight steel sheet, and is evenly distributed in the width of the tire tread pattern block. By setting the wave steel sheet 1 7 as a transverse straight steel sheet, the side of the linear radial groove 1, the linear radial groove 2 2 and the linear radial groove 3 3 can be higher than the other side of the tire. The wave steel sheet 2 8 is a transverse arc steel sheet, and the transverse arc steel sheet is placed within the range of the shoulder pattern block of the tire tread, and there are at least three arc-shaped wave steel sheets, which are distributed according to the width constant of the tread pattern block. By setting the wave steel sheet 2 8 as a transverse arc steel sheet, the side where the linear radial groove 4 4, the linear radial groove 5 5 and the linear radial groove 6 6 are located can be lower than the other side, which is convenient for drainage. The wave steel sheet 1 7 and the wave steel sheet 2 8 both use fine grooves. The setting of fine grooves, on the one hand, keeps the surface of the tire soft, allowing the tread blocks to better contact with the ice and snow road surface, increasing the grip on dry and wet ground, maintaining excellent traction and friction on ice and snow, and maintaining driving comfort at high speeds during the tire's travel.

[0022] See also Figure 2-3 , Figure 2 and Figure 3 The five steps of A, B, C, D and E are staggered, and the stepped groove design of the tread blocks is used to increase the contact area of ​​the tire and ensure the performance of the tire. The half-step design of the groove bottom at A, B, C and E and the full-step design of the groove bottom at D are interspersed within the range of the left and right tread blocks. At the same time, computer optimization theory is used to optimize the performance of the tread block arrangement, thereby reducing the performance frequency generated by the pattern and air, achieving the effect of reducing noise, making the driver and passengers quieter and more comfortable.

[0023] The specific implementation process of the utility model is as follows: the surface of the tire tread is provided with a linear radial groove 1, a linear radial groove 2, a linear radial groove 3, a linear radial groove 4, a linear radial groove 5, and a linear radial groove 6, which are "radial" groove designs. The whole herringbone pattern block is interrupted by a "radiating" groove, so that the pattern after segmentation presents a "radial" visual effect. The surface of the tire tread is provided with a linear radial groove 1, a linear radial groove 2 and a linear radial groove Three 3 form the left tread block, and straight radial groove four 4, straight radial groove five 5 and straight radial groove six 6 form the right tread block. The left and right tread blocks are designed in an asymmetric "radial" manner, which can be seen as N inverted eight-shaped, right eight-shaped and parallel interlaced "radial" groove designs. When the tire is driving, it moves in the direction of the herringbone tread blocks, which increases the tire's grip on icy and snowy roads, and can make the tire have a shorter braking distance under dry and wet conditions, ensuring the safety of tire driving. The left and right tread blocks are assembled into a whole strip block, and the "radial" grooves of the left and right tread blocks are uneven, which more evenly drains the inner and outer sides of the tire and reduces tire side slip and drift at high speeds;

[0024] Moreover, a wavy steel sheet is arranged in each tread pattern block. The waves of the wavy steel sheet 1 7 are transverse straight steel sheets, and the straight wavy steel sheets at the center position are evenly distributed according to the width of the tread pattern block; the waves of the wavy steel sheet 2 8 are transverse arc-shaped steel sheets, and the arc-shaped steel sheets are placed within the range of the shoulder tread pattern block, and there are at least three arc-shaped wavy steel sheets, which are distributed according to the width constant of the tread pattern block; the wavy steel sheet 1 7 and the wavy steel sheet 2 8 use fine grooves, which on the one hand keep the surface of the tire soft, so that the tread pattern block can better contact with the ice and snow road surface, increase the grip on dry and wet ground, maintain excellent traction on ice and snow and friction on ice and snow, and at the same time maintain driving comfort at high speed during the tire driving process.
