Detailed Description
Example 1
As shown in fig. 1-3, the present embodiment provides a structure for improving puncture resistance of a sidewall of an underground mine tire, including a reverse-wrapped carcass steel wire layer 1, where the reverse-wrapped carcass steel wire layer 1 is sequentially provided with a first transition rubber sheet 2, a first fiber reinforced layer 3, a second transition rubber sheet 4, a second fiber reinforced layer 5, and a third transition rubber sheet 6 from inside to outside, where the fiber reinforced layers are existing structures known to those skilled in the art, and a layer of fiber is sandwiched between the two layers of rubber sheets. The first fiber reinforced layer 3 and the turn-up carcass steel wire are 30-45 degrees, the second fiber reinforced layer 5 and the turn-up carcass steel wire are 135-plus-150 degrees, so that the first fiber reinforced layer 3 and the second fiber reinforced layer 5 form a crossed net-shaped structure on the turn-up carcass steel wire layer 1, and when the tire is used, if the tire side part meets a foreign matter cutting tire side, the fiber reinforced layer of the net-shaped structure can effectively protect the turn-up carcass steel wire layer 1 of the tire side, so that the scratch resistance of the tire side is improved, and the service life of the tire is prolonged.
Wherein the material of first transition film 2, second transition film 4 and third transition film 6 is the same with matrix rubber, and 2 thickness of first transition film are 3mm, and 6 thickness of second transition film 4 and third transition film are 1.5mm, and the thickness of first fibre enhancement layer 3 and second fibre enhancement layer 5 is 1.2 mm.
The upper end points of the first transition rubber sheet 2, the first fiber reinforced layer 3, the second transition rubber sheet 4, the second fiber reinforced layer 5 and the third transition rubber sheet 6 exceed the upper end point of the turned-up carcass steel wire layer 1, the upper end point of the first transition rubber sheet 2 exceeds the upper end point of the turned-up carcass steel wire layer 1 by not less than 60mm, and the width of the first transition rubber sheet 2 is 50-80% of the width of the turned-up carcass steel wire layer 1. This is to prevent the stress from concentrating at the upper end of the turned-up carcass steel wire, causing the sidewall to form a weak point at that point.
The upper and lower end points of the first transition film 2, the second transition film 4 and the third transition film 6 exceed the upper and lower end points of the first fiber reinforced layer 3 and the second fiber reinforced layer 5, the width of the upper and lower end points of the second transition film 4 exceeding the upper and lower end points of the first fiber reinforced layer 3 is not less than 10% of the width of the first fiber reinforced layer 3, the widths of the first fiber reinforced layer 3 and the second fiber reinforced layer 5 are the same, but the difference (namely, the vertical dislocation) is 20 mm. All transition films are wider than the fiber reinforced layer, and are adhered together through the transition films respectively between the first fiber reinforced layer 3 and the second fiber reinforced layer 5 and between the first fiber reinforced layer 3 and the reverse-wrapped carcass steel wire layer 1 for the sake of ensuring, because the glue layer on the fiber reinforced layer is thinner, the viscosity is small, if the glue layer on the fiber reinforced layer is adhered directly, the adhesion strength between the two layers of fiber reinforced layers and between the first fiber reinforced layer 3 and the reverse-wrapped carcass steel wire layer 1 is not enough. In this embodiment, the upper end point refers to the end closer to the tread 8, and the lower end point refers to the end farther from the tread 8.
In the embodiment, the first fiber reinforced layer 3 and the second fiber reinforced layer 5 are disposed on the upper portion of the turn-up carcass steel wire layer 1, for example, the width of the turn-up carcass steel wire layer 1 is 450-300 mm, and the width of the first fiber reinforced layer 3 and the second fiber reinforced layer 5 is 200-300 mm. This is because the upper portion of the turned-up carcass ply 1 is generally a portion protruding outward, and the lower portion is a portion recessed inward, so that the puncture generally occurs at the portion protruding outward of the turned-up carcass ply 1, and therefore, the portion needs to be protected against puncture.
The processing technology is as follows:
(1) during the molding process, the tire body is subjected to turn-up and pressing operation according to the normal design;
(2) after the reversely wrapped carcass steel wire layer 1 is pressed, a first transition rubber sheet 2 is additionally attached above the reversely wrapped carcass steel wire layer 1;
(3) attaching a first fiber reinforced layer 3 on the first transition film 2, attaching a second transition film 4 on the first fiber reinforced layer 3, and attaching a second fiber reinforced layer 5 on the second transition film 4; after the fitting is finished, a third transition rubber sheet 6 is additionally fitted, then the two fiber reinforced layer combined bags on the side walls are pressed by using downward pressing, and the pressed fiber reinforced layer combined bags on the side walls are subjected to bubble inspection and corresponding dropping and binding operation;
(4) and continuously attaching, pressing and dropping the tire side component, and finally completing the insertion of the tire side fiber reinforced layer combined bag.
Example 2
On the basis of the embodiment 1, the lower tire shoulder of the tire is provided with a plurality of heat dissipation holes 7, the heat dissipation holes 7 are distributed along the circumferential direction of the tire, and the heat dissipation holes 7 can solve the heat dissipation problem in the rolling process of the tire and prevent the tire from being delaminated and failed in the early stage of the shoulder due to overhigh heat generation of the shoulder of the tire in the using process.
Although the present invention has been described in detail by referring to the drawings in conjunction with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and substance of the present invention, and these modifications or substitutions are intended to be within the scope of the present invention/any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
