Abstract
The invention discloses a special lateral-burst-proof five-layer sidewall TBR tire for a mine, and belongs to the technical field of TBR tires. The technical scheme is as follows: the tire side of the tire comprises an inner liner, a tire body steel wire, an isolation layer, a steel wire wrapping cloth and a tire side rubber from inside to outside in sequence. The invention solves the problem that the safety of the vehicle is influenced by tire burst caused by the problems of severe road conditions, soft use, cut damage of foreign objects on the tire side, puncture of the tire body and the like of the conventional tire, improves the utilization rate of the tire and increases the safety of the tire.
Description
Technical Field
The invention relates to the technical field of TBR tires, in particular to a special lateral-burst-proof five-layer sidewall TBR tire for mines.
Background
The side wall part of the TBR tire used by the existing mine dump truck only comprises a side wall adhesive and a carcass layer, and the tire is instantaneously exploded and fails after being stabbed by a foreign object, so that the running safety of the vehicle is seriously influenced. The tire has the advantages that the tire is damaged due to cutting and piercing of the tire side, and the tire cannot be repaired and used continuously once the tire is damaged, the tire can be discarded, the maximum use value of the tire cannot be exerted, and potential safety hazards and economic losses are caused to users. The higher failure rate leads to the drastic increase of the number of discarded tires and also brings a plurality of adverse effects to environmental protection.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the defects of the prior art are overcome, the five-layer side wall TBR tire special for mine lateral burst prevention is provided, and the problem that the tire burst caused by the problems of side wall cutting, piercing and the like influences the safety of a vehicle due to bad road conditions and soft use of the conventional tire is solved.
The technical scheme of the invention is as follows:
the side-burst-proof five-layer tire side TBR tire special for mines comprises an inner liner, a tire body steel wire, an isolation layer, a steel wire wrapping cloth and a tire side rubber from inside to outside in sequence.
Preferably, the isolation layer comprises cushion rubber and a rubber core, wherein the cushion rubber and the rubber core are overlapped together in the isolation layer to separate the carcass steel wire and the steel wire wrapping cloth.
Preferably, the radius of the upper sidewall arc of the tire is 130-160mm, and the radius of the lower shoulder counter arc is 200-250mm.
Preferably, the steel wire wrapping cloth is reversely wrapped to the anti-friction boss of the tire shoulder.
Preferably, the angle between the steel wire wrapping cloth and the steel wire of the tire body is 20-30 degrees.
Compared with the prior art, the invention has the following beneficial effects:
1. the traditional TBR tire side wall comprises an inner liner, a tire body and a sidewall rubber, the function of resisting impact cutting of foreign objects at the side wall part is almost negligible, the side wall of the TBR tire sequentially comprises the inner liner, a tire body steel wire, an isolation layer, a steel wire wrapping cloth and a sidewall rubber five-layer structure from inside to outside, the problem that the tire burst caused by the problems that the tire side is cut by the foreign objects, the tire body is punctured and the like to influence the safety of a vehicle can be greatly reduced under severe road conditions, the utilization rate of the tire is improved, and the safety of the tire is improved.
2. The tire provided by the invention has the advantages that even if foreign objects damage the steel wire wrapping cloth, the tire body is not damaged, the tire can be continuously used after being repaired by a user, the service life of the tire is prolonged by more than 50%, and the use cost of the tire is greatly reduced for the user.

FIG. 1 is a schematic diagram of the present invention.
Fig. 2 is a partially enlarged view of a portion a in fig. 1.
In the figure, 1-an inner liner, 2-a tire body steel wire, 3-a steel wire wrapping cloth, 4-sidewall rubber, 5-cushion rubber, 6-a rubber core, 7-an upper sidewall arc, 8-a lower shoulder reverse arc and 9-an anti-friction boss.
Detailed Description
Example 1
As shown in fig. 1-2, the present embodiment provides a five-layer sidewall TBR tire for mine dedicated side burst prevention, where a sidewall of the tire sequentially includes five layers of structures, namely, an inner liner 1, a carcass steel wire 2, an isolation layer, a steel wire wrapping cloth 3 and sidewall rubber 4, from inside to outside, and the isolation layer includes a cushion rubber 5 and a rubber core 6; the cushion rubber 5 in the isolating layer is lapped with the rubber core 6 together to isolate the carcass steel wire 2 and the steel wire wrapping cloth 3, so that the problem of delamination caused by the interaction of the carcass steel wire 2 and the steel wire wrapping cloth 3 is reduced; the radius of the upper tire side arc 7 of the tire is 130-160mm, the radius of the upper tire side arc 7 is smaller than that of an upper tire side arc value of a traditional mining TBR tire, the radius of the lower shoulder counter arc 8 is 200-250mm and larger than that of the traditional mining TBR tire, the small upper tire side arc 7 and the large lower shoulder counter arc 8 are adopted, the sinking amount of the tire in an inflated state is guaranteed through the design of the outer contour of the tire, and the probability that the tire side is scratched by road stones is reduced. Wherein, the wedge 5 is positioned at the tire shoulder and is a filling component for separating the belted layer and the tire body, which can reduce the heat generation of the tire shoulder; the rubber core 6 is positioned above the steel wire ring of the ring part and fills the ring part to play a supporting role.
Example 2
On the basis of the embodiment 1, the steel wire wrapping cloth 3 is wrapped to the anti-friction boss 9 of the tire shoulder, the stress strain of the wrapping end point is reduced, the early-stage delaminating and bulging of the tire shoulder caused by overhigh wrapping end point is avoided, the shoulder deformation area can be avoided, the overall strength of the tire side is increased by two layers of steel wires at the whole tire side part, and meanwhile, the outer steel wire wrapping cloth 3 can prevent the inward growth of trauma and protect the tire body.
Example 3
On the basis of the embodiment 2, the angle between the steel wire wrapping cloth 3 and the tire body steel wire 2 is 20-30 degrees, through calculation and analysis, the small-angle steel wire wrapping cloth 3 is adopted, the reinforcing effect of the steel wire wrapping cloth 3 on the ring part can be ensured, the anti-puncturing performance of the tire side part is improved, and the angle is more convenient for reversely wrapping the steel wire wrapping cloth 3 to the anti-friction boss 9 of the tire shoulder during forming.
Although the present invention has been described in detail by referring to the drawings in connection 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 scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the 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.
