Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically to a studded snow tire tread structure. Background Technology
[0002] On icy and snowy roads in winter, a film of water forms. When ordinary tires drive on this surface, the reduced friction makes them prone to slipping, leading to dangerous accidents. Studded snow tires, with their numerous studs, can effectively pierce this water film and provide excellent grip. However, the presence of these studs can also damage the road surface when driving on shallow snow or ordinary roads, causing disputes and complaints. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a studded snow tire tread structure that can solve the technical problem that existing studded snow tires cause road damage when driving on shallow snow or ordinary roads, thus causing disputes and complaints.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A studded snow tire tread structure includes a tire tread with a shoulder tread block, a longitudinal groove, a secondary intermediate tread block, an intermediate tread block, a secondary intermediate tread block, a longitudinal groove, and a shoulder tread block arranged sequentially from left to right on the tire tread. The shoulder tread block, the secondary intermediate tread block, and the intermediate tread block are all provided with stud holes. The stud holes are distributed on the entire circumference of the tire tread. Tread blocks are arranged around the outer periphery of the stud holes. The tread blocks include tooth-shaped tread blocks and double-layer tooth-shaped tread blocks, which are spaced apart along the outer periphery of the stud holes.
[0006] Preferably, the inner radius R2 of the patterned block is equal to the radius of the pin hole R1 + (0.5~1mm), and the outer radius R3 is equal to 5~8mm.
[0007] Preferably, the cross-sectional shape of the tooth-shaped pattern block is trapezoidal, with a height H1 of 0.2~0.3mm and an angle α of 10°~15°.
[0008] Preferably, the cross-sectional shape of the double-layer tooth-patterned block is a double-layer trapezoid. The shape of the lower trapezoid is the same as that of the tooth-patterned block. The height H2 of the upper trapezoid is 0.2~0.3mm, the angle β is 5°~8°, and the single-side difference L1 between the upper and lower trapezoids is 0.1~0.2mm.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting patterned blocks around the nail holes, this utility model can reduce the damage to the road surface caused by the nails on the nailed snow tires, and can further improve the grip of the nailed snow tires, thereby reducing disputes and complaints and improving customer satisfaction.

[0017] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments.
[0018] like Figures 1 to 4 As shown, this utility model discloses a studded snow tire tread structure, including a tire tread. From left to right, the tire tread is provided with a shoulder tread block 1, a longitudinal groove 2, a secondary intermediate tread block 3, an intermediate tread block 4, another secondary intermediate tread block 3, a longitudinal groove 2, and a shoulder tread block 1. Each of the shoulder tread block 1, the secondary intermediate tread block 3, and the intermediate tread block 4 is provided with a stud hole 5 for installing studs. The stud holes 5 are distributed on the entire circumference of the tire tread and are randomly distributed along with the tire tread blocks. Tread blocks 6 are provided on the outer periphery of the stud holes 5. The tread blocks 6 include tooth-shaped tread blocks 61 and double-layer tooth-shaped tread blocks 62. The tooth-shaped tread blocks 61 and double-layer tooth-shaped tread blocks 62 are arranged at intervals along the outer periphery of the stud holes 5.
[0019] Furthermore, in this embodiment, the inner radius R2 of the patterned block 6 is equal to the radius of the rivet hole R1 + 1mm, the radius of the rivet hole R1 is 2.5mm, the inner radius R2 of the patterned block 6 is 3.5mm, and the outer radius R3 is 7mm.
[0020] Furthermore, in this embodiment, the cross-sectional shape of the tooth-shaped pattern block 61 is trapezoidal, with a height H1 of 0.2 mm and an angle α of 12°. When the studs on the studded snow tire pierce the water film, the water can be drained by the tooth-shaped pattern block 61, thereby improving the efficiency of piercing the water film and improving the grip of the studded snow tire.
[0021] Furthermore, in this embodiment, the cross-sectional shape of the double-layer tooth-patterned block 62 is a double-layer trapezoid. The shape of the lower trapezoid is the same as that of the tooth-patterned block 61, and the height H2 of the upper trapezoid is 0.2mm, the angle β is 7°, and the single-side difference L1 between the upper and lower trapezoids is 0.15mm. The double-layer tooth-patterned block 62 can achieve sufficient support height and reduce the damage to the road surface caused by the studs on the studded snow tire.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
