Description

Lining composite part for improving tire bead exposure

Technical Field

The utility model belongs to the technical field of radial tires, and particularly relates to a lining composite part for improving tire bead exposure.

Background

Tires are one of the important components of automobiles, and existing tire shoulder structures mainly include innerliners, transition layers, carcasses, carcass plies, shoulder liners, crown and sidewalls.

In the actual production process of the existing tire shoulder, the problems of exposed tire bead lines, influence on product quality and certain limitations are easily caused due to the fact that the size and quality of a semi-finished product fluctuate, the Mooney viscosity of a transition layer sizing material is too low, the assumed stretching value of a tire body cord is too large, the process parameters are controlled improperly during molding, the vulcanization process fluctuates and the like.

Disclosure of Invention

The utility model aims to provide a lining composite part for improving the tire bead wire, which solves the problems that the tire bead wire is easily exposed, the product quality is influenced and certain limitation exists in the actual production process of the existing tire shoulder in the background technology due to the fluctuation of the size and the quality of a semi-finished product, the too low Mooney viscosity of a transition layer rubber material, the too large assumed stretching value of a tire body cord, improper control of process parameters during molding, fluctuation of a vulcanization process and the like.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an improve inside lining complex piece of tire tread dew, includes the tire shoulder, the tire shoulder includes the inner liner, the filter layer, the matrix body, matrix film, the shoulder pad is glued, the crown, side wall and inner liner film, surface one side fixedly connected with inner liner film of filter layer, the inner liner film is symmetrical arrangement.

Preferably, the outer surface fixedly connected with filter layer of inner liner, surface one side fixedly connected with matrix body of filter layer, the inner liner film is located between filter layer and the matrix body.

Preferably, the outer surface of the carcass body is fixedly connected with a carcass film, and the outer surface of the carcass film is fixedly connected with a shoulder cushion.

Preferably, the outer surface of the upper end of the shoulder pad is fixedly connected with a tire crown, and two sides of the tire crown are fixedly connected with tire sidewalls.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model improves the traditional double composite design of the lining (the inner liner and the transition layer) into the three composite design of the inner liner, the transition layer and the rubber/film, wherein the rubber material adopts the same formula as the transition layer, and the thickness, the width and the bonding position can be adjusted according to the requirement so as to be suitable for the use of tires with different specifications.

2. The utility model can effectively solve the problems that the interval between the tire body cords is increased, the tire cord rubber is insufficient, the inner liner butyl rubber is permeated, and the tire body cords are excessively large in supposition stretching value and the like due to the fluctuation of the size and the quality of half parts and the Mooney viscosity of a transition layer when the prior equipment is not transformed spatially or has insufficient funds in the manufacturing process of the tire.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides an improve inside lining complex of tire tread dew line, includes tire shoulder 9, and tire shoulder 9 includes inner liner 1, filter layer 2, matrix body 3, matrix film 4, shoulder area is by 5, crown 6, side wall 7 and inner liner film 8, and the surface one side fixedly connected with inner liner film 8 of filter layer 2, and inner liner film 8 is symmetrical arrangement.

In this embodiment, the lining composite is changed from double composite to triple composite, as shown in fig. 2, the original lining composite is changed from the inner liner 1+filter layer 2 to the inner liner 1+filter layer 2+liner film 8 of fig. 3, so as to achieve the purpose of supplementing the thickness of the shoulder rubber, the rubber of the liner film 8 adopts the same formulation as the transition layer, and the thickness, width and attaching position can be adjusted as required.

Specifically, the outer surface fixedly connected with filter layer 2 of inner liner 1, the surface one side fixedly connected with matrix body 3 of filter layer 2, inner liner film 8 is located between filter layer 2 and matrix body 3.

In this embodiment, the purpose of supplementing the thickness of the shoulder stock can be achieved by providing the carcass body 3.

Specifically, the outer surface of the carcass body 3 is fixedly connected with a carcass film 4, and the outer surface of the carcass film 4 is fixedly connected with a shoulder cushion 5.

In this embodiment, the strength of the shoulder 9 of the tire can be enhanced by the carcass film 4 and the shoulder pad 5 being provided.
