Description

Anti-merging bead tire structure

Technical Field

The utility model relates to a tire technical field specifically relates to a prevent and rim of a mouth tire structure.

Background

With the development of the tire industry, the tire manufacturing technology is higher and higher, and for car tires, customers not only require the tires to be wear-resistant, durable and low in price, but also require low oil consumption, comfort and beautiful appearance. In the case of high-section tires, particularly tires of 65 series or more, deformation and bead merging phenomena occur during storage and transportation after production, and bead merging means that the tire mounting is difficult due to the fact that the bead spacing is too small, and the tire mounting is difficult and inefficient. To solve this problem, the sidewall stiffness is generally increased, but simply increasing the sidewall stiffness has little effect on improving the bead performance and increases the cost. The reason of the tire seam allowance is as follows:

1. insufficient rigidity of the sidewall

The high-section radial tire has insufficient rigidity of the sidewall, so that the sidewall is seriously deformed when the tire is stored for a long time, thereby causing rim merging. The lack of rigidity of the sidewall is generally determined by the thickness and specification of the sidewall material, and the increase of the thickness and the change of the specification of the sidewall material are bound to improve the seam allowance, but the effect is not obvious, the cost is increased greatly, and the cost and the comfort are not reduced.

2. Unreasonable parameter setting of post-inflation height

Another reason for the merging of the bead of the high-section radial tire is that the bead width is too small after the tire is vulcanized due to unreasonable post-inflation height parameter setting, and the bead deforms after storage and long-distance transportation, thereby causing difficulty in tire installation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevent and bead tire structure increases special design's rubber in tire carcass cord child shoulder position, not only can not reduce the travelling comfort of tire, can effectual increase shoulder carcass rigidity intensity moreover to increase the rigidity of side wall, prevent the emergence of tire and bead phenomenon.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model relates to a tire structure for preventing merging seam, which comprises a left outer tire shoulder, a first layer of tire body cord fabric, an inner liner and a right inner tire shoulder; the left outer rubber is arranged at the left outer tire shoulder position of the tire carcass cord, and the right outer rubber is arranged at the right inner tire shoulder position of the tire carcass cord; the left outer rubber and the right outer rubber are symmetrically arranged; the left outer rubber and the right outer rubber are both positioned between the first carcass ply and the inner liner and are bonded with the carcass cord and the inner liner.

Further, the distance between the inner starting endpoint of the left outer rubber and the left outer shoulder endpoint is 20mm-35 mm.

Furthermore, the width of the left outer rubber and the width of the right outer rubber are both 40mm-70mm, the thickness of the left outer rubber and the right outer rubber are 1.0mm-1.5mm, and the length of the left outer rubber and the right outer rubber is one circle in the circumferential direction of the tire.

Furthermore, the Shore hardness range of the left outer rubber and the right outer rubber is 68-78 degrees, and the rigid support of the tire shoulder can be increased.

The technical effects of the utility model:

compared with the prior art, the utility model relates to a prevent and rim of a mouth tire structure, to high section tire, especially the tire more than 65 series is after piling for a long time and pressing and transportation extrusion, because the utility model discloses there is the special design's of the rigidity that excels in and resilience rubber at tire shoulder, the original outward appearance shape of recovery very fast of tire ability to avoid rim of a mouth and the side wall of tire to warp, and improve dress child efficiency.
