Abstract
The invention relates to a tire transition layer structure which comprises a tire transition layer and an airtight layer. A first nylon woven cloth rubber piece and a second nylon woven cloth rubber piece are arranged symmetrically on two sides of the tire transition layer and arranged at a position of 40-70 mm away from a central line of the tire transition layer. The tire transition layer structure is simple in structure and compact in design; by arranging the first nylon woven cloth rubber piece and the second nylon woven cloth rubber piece, steel wire exposure in a tire due to nonuniform local stress at a position, with small curvature radius, on the lower portion of a tire shoulder is effectively reduced, U-shaped bursting of the tire in the process of use is reduced, and quality of the tire is improved.
Description
Technical field
The present invention relates to a kind of Tire transition layer structure, belong to tire design technical field.
Background technology
Takeing on lower portion at all-steel radial tyre, be close to transition zone and inner liner inside carcass, outside is then sidewall or pad glue.Owing to this position radius of curvature is less, in tire building and sulfidation, carcass is susceptible to mobile by the active position of tension force, the symptom of semi-finished product, finished product vaginal bleeding during pregnancy steel wire occurs.The tire of slight bleed-out silk is in use breakneck, it is easy to causes and blows out, and causes serious potential safety hazard；The tire of serious bleed-out silk becomes waste product, reduces the profit of enterprise, causes the waste of resource.
The Mooney of elastomeric compound is on the low side, and part dimension is defective, and molding location is inaccurate, and the air etc. not drained between unreasonable use and capsule and the fetus of curing bag all can cause tyre cavity bleed-out silk.Adopt these measures can reduce tyre cavity bleed-out silk symptom to a certain extent, but still cannot effectively reduce tyre cavity bleed-out silk symptom.In the process of molding or sulfuration, inner liner sizing material, transition zone sizing material, carcass are by transverse shear stress and longitudinally uphold.From microcosmic angle, carcass belongs to one-dimensional linear with transition zone, inner liner and contacts.When tension distribution is uneven, one-dimensional linear contact easily causes stress and concentrates.Thus, carcass cord position is likely to move cause tyre cavity bleed-out silk to transition zone, inner liner.Line opposite is a kind of good stress decentralized model.When local stress skewness, the way of contact of carcass and transition zone is contacted by one-dimensional linear and changes over the contact of two-dimensional line face, stress concentration can be dropped well, keep the relative position of carcass, transition zone, inner liner, reduce tyre cavity bleed-out silk symptom.
Nylon is the polymer that a kind of main chain contains recurring amide radical group.It has the mechanical property of excellence, thermostability and wearability, has good humidification with the adhesive glue of silica-hexa-resorcinol system.One-dimensional nylon through spinning prepare into two dimension spin cloth after by the functional improvement of its excellence to two-dimensional surface, effectively disperseing of local and carcass contact stress can be suitable for.
Summary of the invention
The invention aims to solve wheel tire shoulder lower portion carcass because of radius of curvature little, in molding and sulfidation, carcass position under tension is susceptible to the mobile problem causing bleed-out silk phenomenon, provide a kind of simple in construction, Tire transition layer structure compact to design, the tire shoulder bottom carcass stress to transition zone and inner liner can be disperseed, reduce the symptom of tyre cavity bleed-out silk.
The present invention adopts the following technical scheme that a kind of Tire transition layer structure, including Tire transition layer and inner liner, the lateral symmetry of described Tire transition layer is provided with the first nylon shioze cloth film and the second nylon shioze cloth film, and described first nylon shioze cloth film and the second nylon shioze cloth film are arranged at Tire transition layer centrage 40～70mm place.
Further, described first nylon shioze cloth film and the second nylon shioze cloth film are three-decker, respectively go up film layers and lower film layers, described upper film layers and lower film interlayer and are provided with nylon shioze layer of cloth.
Further, described nylon shioze layer of cloth being provided with some rectangular mesh, the length of side of described rectangular mesh is 0.4～2.5mm.
Further, the thickness of described first nylon shioze cloth film and the second nylon shioze cloth film is 0.5～3mm.
Further, the width of described first nylon shioze cloth film and the second nylon shioze cloth film is 100～160mm.
Present configuration is simple, compact to design, the setting of the first nylon shioze cloth film and the second nylon shioze cloth film effectively reduces the tyre cavity bleed-out silk symptom that tire shoulder bottom radius of curvature smaller part causes due to local stress inequality, reduce tire U-shaped in use quick-fried, improve the quality of tire.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1-Figure 3, a kind of Tire transition layer structure, including Tire transition layer 1 and inner liner 2, the lateral symmetry of Tire transition layer 1 is provided with the first nylon shioze cloth film 3 and the second nylon shioze cloth film 4, first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 are arranged at Tire transition layer 1 centrage 40～70mm place, the thickness of the first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 is 0.5～3mm, the width of the first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 is 100～160mm, first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 are three-decker, respectively go up film layers 5 and lower film layers 6, it is provided with nylon shioze layer of cloth 7 between upper film layers 5 and lower film layers 6.Being provided with some rectangular mesh on nylon shioze layer of cloth 7, the length of side of rectangular mesh is 0.4～2.5mm.
The one-dimensional linear of local carcass with Tire transition layer 1 and inner liner 2 is contacted the contact changing into line opposite with the second nylon shioze cloth film 4 by the first nylon shioze cloth film 3 that Tire transition layer both sides have, and is effectively reduced molding, vulcanizes the symptom of the tyre cavity bleed-out silk that tire shoulder position on the lower side is caused due to stress concentration in type-approval process.
