[0003] At present, when riding on special terrain, especially on sand or soft ground, it is very difficult to push the tires, let alone ride. And when climbing or riding on irregular roads, ordinary tires cannot grip the uneven ground and cannot provide enough traction, which restricts the movement. It greatly reduces the driver's experience and the feeling of outdoor sports.
[0004] Therefore, a puncture-resistant steel wire fat tire is still needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0019] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.
[0020] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.
[0021] Reference Figure 1-3The utility model provides a puncture-resistant steel wire fat tire, which includes, from the inside to the outside, a reinforcement layer, a tread buffer layer 2 and a tread layer 3. The reinforcement layer includes a first reinforcement layer 11 and a second reinforcement layer 12. The first reinforcement layer 11 and the second reinforcement layer 12 are stacked on both sides of the first reinforcement layer 11, and the thickness gradually decreases from both sides to the middle of the tire. The buffer layer is attached to the first reinforcement layer 11 and covers at least part of the edge of the second reinforcement layer 12. The tread layer 3 covers the outside of the buffer layer. The reinforcement layer includes two layers. The edges of the second reinforcement layer 12 overlap on both sides of the first reinforcement layer 11. The outer surface of the first reinforcement layer 11 is the airbag cavity of the tire. The thin-walled edge of the second reinforcement layer 12 with a gradually decreasing thickness trend is connected to the first reinforcement layer 11 by bonding. Then the tread buffer layer 2 covers the first reinforcement layer 11 and covers the connecting edge of the first reinforcement layer and the second reinforcement layer 12. When a vehicle with the tire travels on sandy or soft ground, the connection between the first reinforcement layer 11 and the second reinforcement layer 12 makes the interior of the tire airbag coordinated as a whole and not easily deformed. It can stably cooperate with the top buffer layer and the tread layer 3, so that the buffer layer helps maintain the shape of the tire and provides good grip. Even when traveling on uneven roads, it can provide good traction through its stable shape.
[0022] In one embodiment, the reinforcing layer is a bias ply of cotton fibers, which increases the stability and load-bearing capacity of the tire by arranging the fibers crosswise at a certain angle, usually not completely vertical or horizontal.
[0023] In one embodiment, the tread buffer layer 2 is a steel wire ring belt, which provides the tire with puncture resistance.
[0024] In one embodiment, a wire ring 4 is provided between the first reinforcement layer 11 and the second reinforcement layer 12 near the joint with the wheel hub to prevent air leakage due to poor fit between the surface contacting the wheel hub.
[0025] In one embodiment, a wear-resistant layer 5 is provided at the outer side of the second reinforcement layer 12 corresponding to the connection with the wheel hub. The material of the wear-resistant layer 5 can be a highly wear-resistant rubber material to ensure good durability of the tire.
[0026] In one embodiment, the outer side of the tread layer 3 is formed with a first pattern block 6 and a second pattern block 7 on the tread center axis on the surface corresponding to the ground, and a third pattern block 8 and a fourth pattern block 9 are arranged on both sides of the first pattern block 6 or the second pattern block 7, the first pattern block 6 and the second pattern block 7 are arranged alternately on the center axis, the third pattern block 8 is distributed in a V shape on both sides of the first pattern block 6, and the fourth pattern block 9 is distributed in a V shape on both sides of the second pattern block 7. Each pattern block is provided with a trapezoidal reinforcement, and the lateral spacing and longitudinal spacing of each adjacent pattern block are equal. The nearly uniform distribution of each pattern block makes the bicycle tire of the present invention highly maneuverable and has water and mud discharge performance. The overall passability of the tire is improved.
[0027] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
