Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a low-noise, high-humidity ski radial tire. Background Art

[0002] In order to ensure safety performance on snow and ice, snow tires use special patterns, more steel plates, and deeper tread grooves, which makes them noisier than ordinary summer tires and all-season tires. However, with the improvement of living standards, car owners have higher and higher requirements for comfort and noise during travel. After replacing winter tires in winter, the noise of the vehicle is louder than that of summer tires, causing complaints from car owners. In addition, many cities will use snow melting agents on the road after snowfall to reduce snow on the road, resulting in water accumulation on urban roads. Most snow tires pay more attention to safety performance on snow and icy roads, but ignore the safety of water accumulation after the snow melts. Therefore, a low-noise, high-humidity snow radial tire is needed to meet the demand. Utility Model Content

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figure 1 , a low-noise high-wet snow skiing radial tire, including a shoulder tread block 1 and a central tread block 2. The shoulder tread block 1 and the central tread block 2 are both radially arranged on the tire tread. The tire tread is symmetrically designed, from the outside to the inside, from the shoulder tread block 1 to the central tread block 2;

[0021] The central tread block 2 is in the shape of a wing. The non-through-type first diagonal groove 10, non-through-type second diagonal groove 11, first diagonal groove 4, second diagonal groove 5, third diagonal groove 6, and fourth diagonal groove 7 are arranged on the central tread block 2;

[0022] The second zigzag 3D cutter groove steel sheet 13, third zigzag 3D cutter groove steel sheet 14, fourth zigzag 3D cutter groove steel sheet 15, fifth zigzag 3D cutter groove steel sheet 16, and longitudinal steel sheet 19 are also arranged on the central tread block 2;

[0024] A longitudinal groove 3 is arranged between the central tread block 2 and the shoulder tread block 1;

[0025] A transverse groove 8 is arranged between two adjacent shoulder tread blocks 1;

[0026] The first zigzag 3D cutter groove steel sheet 12, first diagonal steel sheet 17, and second diagonal steel sheet 18 are arranged on the shoulder tread block 1.

[0027] By optimizing the pattern shape and arrangement, the tire noise is effectively reduced, the noise problem of snow tires is improved, and the problems in the prior art are solved, that is, when the snow on the road surface melts and there is water accumulation, the wet skid performance of the snow meridian tire decreases and there is a risk of tire skidding. At the same time, on the basis of ensuring the snow performance.

[0028] Specifically, in this embodiment, the groove width of the through-type V-shaped groove 9 is 3 mm to 8 mm, and the depth is 6 to 10 mm; the groove widths of the non-through-type inclined groove one 10 and the non-through-type inclined groove two 11 are both 2 to 7 mm, and the depths are both 6 to 10 mm; the angles of the through-type V-shaped groove 9, the non-through-type inclined groove one 10, and the non-through-type inclined groove two 11 are all 100 to 160 degrees; the width of the inclined groove one 4 is 0.6 to 1.2 mm, the width of the inclined groove two 5 is 2 to 5 mm, the width of the inclined groove three 6 is 2.5 to 6 mm, and the width of the inclined groove four 7 is 0.4 to 4 mm.

[0029] The non-through-type inclined groove design improves the pattern rigidity, enhances the tire grip, and at the same time can block the noise and effectively reduce the noise. The large-angle V-shaped groove drains water and snow more smoothly, improving the wet skid performance.

[0030] Specifically, in this embodiment, the numbers of the zigzag 3D stereo knife groove steel sheets two 13 and the zigzag 3D stereo knife groove steel sheets five 16 are 4 to 10 respectively, the number of the zigzag 3D stereo knife groove steel sheets three 14 is 2 to 6, the number of the zigzag 3D stereo knife groove steel sheets four 15 is 6 - 12, and the number of the longitudinal steel sheets 19 is 4 - 11.

[0031] Specifically, in this embodiment, the width of the longitudinal groove 3 is 5 to 15 mm, and the depth is 4 to 8 mm; the width of the transverse groove 8 is 4 to 12 mm, and the depth is 2 to 8 mm. The longitudinal groove 3 ensures excellent grip and braking force of the tire on snow and wet road surfaces. The widened longitudinal groove 3 can have a greater drainage volume and stronger wet skid performance on the basis of ensuring the snow drainage function.

[0032] Specifically, in this embodiment, the zigzag 3D stereo knife groove steel sheet one 12, the inclined steel sheet one 17, and the inclined steel sheet two 18 all adopt zigzag 3D stereo knife groove steel sheets to balance the pattern block rigidity, make the pattern softer, increase the pattern contact area, and ensure the handling performance when the vehicle turns.
