Description

Technical Field

[0001] This utility model relates to the field of studded tire technology, specifically a studded tire with a novel stud hole structure. Background Technology

[0002] Studded snow tires are primarily used in extremely cold regions. Winter roads are typically covered in thick snow, making driving exceptionally difficult and posing safety hazards. Therefore, a studded snow tire is needed to improve a vehicle's grip and traction on icy and snowy roads.

[0003] Unlike non-studded snow tires, studded snow tires offer greater flexibility due to the presence of stud holes in their tread pattern. Studded tires provide stronger grip and can handle more severe snow and icy conditions, making it crucial for studded snow tires to ensure the studs are securely embedded in the holes.

[0004] However, existing studded tires have cylindrical studs, which do not provide good fixation for the studs inside the tire. The studs are prone to falling off, and the stud holes at the tire parting line are often cracked due to uneven stress, which can lead to poor contact between the studs and the tire and cause studs to fall off, affecting tire performance.

[0005] Based on this, a nail insert with a novel nail hole structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a nail-mounted insert with a novel nail hole structure to solve the problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A studded tire with a novel stud hole structure includes a tire body and a tread, wherein the tread is located on the outer side of the tire body, and the tread has tread blocks with anti-slip studs on the tread blocks.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] In one alternative: the anti-skid studs include a first anti-skid stud and a second anti-skid stud, both of which are disposed on the tread block, wherein the second anti-skid stud is disposed at the tire parting seam.

[0011] In one alternative: the first anti-slip stud includes a first inlay portion, a first ground portion, and a first protrusion portion. The first ground portion is located at the upper end of the first inlay portion, and the first protrusion portion is located at the upper end of the first ground portion. The first inlay portion, the first ground portion, and the first protrusion portion are cylindrical structures of different sizes.

The second grounding portion is located at the upper end of the second inlay portion, and the second protrusion portion is located at the upper end of the second grounding portion. The second grounding portion and the second protrusion portion are cylindrical structures of different sizes, and the second inlay portion is an arc-shaped protrusion.

[0013] In one alternative embodiment: the patterned block is provided with nail holes for installing a first anti-slip nail and a second anti-slip nail. The structural dimensions of the nail holes match the first anti-slip nail and the second anti-slip nail. The depth of the nail hole for installing the second anti-slip nail is 9.4 mm, the diameter of the second inlay portion inside the nail hole for installing the second anti-slip nail is 2.5 mm, the diameter of the second grounding portion inside the nail hole for installing the second anti-slip nail is 6 mm, and the thickness is 0.2 mm.

[0014] In one alternative: the tread is provided with a reinforcing steel wire layer, which is located below the nail hole.

[0015] In one alternative: the inner side of the tread is provided with a sound-absorbing material layer, which is formed of porous polyurethane foam with greater than 20% elasticity.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] In one embodiment, such as Figure 1 As shown, a studded tire with a novel stud hole structure includes a tire body 100 and a tread 200. The tread 200 is located on the outside of the tire body 100. The tread 200 is provided with tread blocks 201 and anti-skid studs 300. Through the combined action of the tread blocks 201 and the anti-skid studs 300, the tire's grip is effectively improved.

[0032] In one embodiment, the anti-skid stud 300 includes a first anti-skid stud 400 and a second anti-skid stud 500, both of which are disposed on the tread block 201, wherein the second anti-skid stud 500 is disposed at the tire parting seam.

[0033] In one embodiment, such as Figure 2As shown, the first anti-slip stud 400 includes a first inlay portion 401, a first grounding portion 402, and a first protrusion portion 403. The first grounding portion 402 is located at the upper end of the first inlay portion 401, and the first protrusion portion 403 is located at the upper end of the first grounding portion 402. The first inlay portion 401, the first grounding portion 402, and the first protrusion portion 403 are cylindrical structures of different sizes.

[0034] In one embodiment, such as Figure 4 As shown, the second anti-slip stud 500 includes a second inlay portion 501, a second grounding portion 502, and a second protrusion portion 503. The second grounding portion 502 is located at the upper end of the second inlay portion 501, and the second protrusion portion 503 is located at the upper end of the second grounding portion 502. The second grounding portion 502 and the second protrusion portion 503 are cylindrical structures with different sizes, and the second inlay portion 501 is an arc-shaped protrusion.
