Description

All-steel load-bearing radial tire protects bead structure

Technical field

The utility model relates to a kind of all-steel load-bearing radial tires to protect bead structure, and in particular to a kind of pair of tyre bead is anti- A kind of improved structure of packet strengthening course, belongs to automobile tire technical field.

Background technique

With the development and progress of country, all-steel load-bearing radial tire using more and more, to the bead part of tire The lifting capacity of position proposes the requirement of more Gao Gengxin, but since all-steel load-bearing radial tire is due to conditions such as loads and speed Lower tyre bead portion stress is concentrated, heat is excessively high, the problems such as splitting outside rim of the mouth usually occurs.Breakdown point is split outside rim of the mouth often appears in carcass Cord anti-package endpoint and steel wire rim of the mouth anti-package endpoint.The structure of all-steel radial tyre continues to develop in recent years, uses steel wire Mouth covering carcass anti-package endpoint is to protect the technology of its carcass anti-package endpoint dispersive stress have been relatively mature, but steel wire rim of the mouth is anti- The stress of packet endpoint disperses or safeguard measure is not solved effectively also.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned shortcomings, provide a kind of all-steel load-bearing radial tire protection tyre bead Structure improves the service life of tire, promotes the security performance of tire, while improving its production efficiency to a certain extent.

The technical solution of the utility model, all-steel load-bearing radial tire protect bead structure, including triangular part, steel wire Circle, carcass, transition zone, inner liner and wear-resisting glue；The triangular part is fitted tightly on wire loop, and wire loop bottom is equipped with tire Body, carcass lower section are successively bonded transition zone, inner liner and wear-resisting glue；

It further include carcass ply, steel wire rim of the mouth and nylon rim of the mouth；Carcass ply is set on the outside of the triangular part, in transition zone Steel wire rim of the mouth is arranged in portion；The nylon rim of the mouth is coated on steel wire rim of the mouth two sides.

The carcass ply and steel wire rim of the mouth are separated by nylon rim of the mouth.

The nylon rim of the mouth far-end film stock thickness is greater than proximal end film stock thickness；The film width of nylon rim of the mouth far-end Greater than the film width of proximal end.

The utility model has the beneficial effects that the utility model solves all-steel load-bearing radial tire body cord anti-package endpoint And steel wire rim of the mouth anti-package endpoint stress is concentrated, the excessive problem of heat reduces the problems such as splitting outside rim of the mouth, and that improves tire uses the longevity Life, promotes the security performance of tire, while improving its production efficiency to a certain extent.

Specific embodiment

As shown in Figure 1, all-steel load-bearing radial tire protects bead structure, including triangular part 1, wire loop 2, carcass 3, mistake Cross layer 4, inner liner 5 and wear-resisting glue 6；The triangular part 1 is fitted tightly on wire loop 2, and 2 bottom of wire loop is equipped with carcass 3, tire 3 lower section of body is successively bonded transition zone 4, inner liner 5 and wear-resisting glue 6；

It further include carcass ply 7, steel wire rim of the mouth 8 and nylon rim of the mouth 9；Carcass ply 7, mistake are set on the outside of the triangular part 1 Cross setting steel wire rim of the mouth 8 inside layer 4；The nylon rim of the mouth 9 is coated on 8 two sides of steel wire rim of the mouth.

The carcass ply 7 and steel wire rim of the mouth 8 are separated by nylon rim of the mouth 9.

The 9 far-end film stock thickness of nylon rim of the mouth is greater than proximal end film stock thickness；The film of 9 far-end of nylon rim of the mouth is wide Degree is greater than the film width of proximal end.

Existing steel wire rim of the mouth anti-package endpoint is simply covered by nylon rim of the mouth substantially or the plain modes such as film anti-package covering It is protected, the utility model is protected using the mode of 9 anti-package of nylon rim of the mouth covering 8 anti-package endpoint of steel wire rim of the mouth.This reality With novel by edge encapsulated of original steel wire rim of the mouth endpoint position cancellation, use the replacement of nylon rim of the mouth 9 instead, and nylon rim of the mouth 9 compared with Remote film stock thickness increased, and width increases, and specifically depends on the circumstances according to different size tire.Carcass ply 7 and steel wire Rim of the mouth is separated between 8 anti-package region by nylon rim of the mouth 9, no longer can need to fill film, improves production efficiency, and production process is simple Change.

The utility model has following advantage:

1, since the intensity in nylon rim of the mouth is higher than common film, the fragile bad point of tyre bead, while nylon are more effectively protected Mouth plays steel wire to the over effect of rubber, and the stress of steel wire rim of the mouth anti-package endpoint location is allowed effectively to discharge and delay Solution.

2, nylon rim of the mouth is filled in the turn-up position of steel wire rim of the mouth and carcass ply in the inner part, makes steel wire rim of the mouth and carcass It is effectively separated between cloth, steel wire rim of the mouth and carcass ply stress is avoided excessively to concentrate heat excessive.

3, the use in nylon rim of the mouth is filled instead of raw steel silk rim of the mouth edge film and steel wire rim of the mouth and carcass ply anti-package Film, production efficiency improve, and production process summary is more suitable for efficiently producing.
