Abstract
The utility model relates to a tire transition layer structure, including tire transition layer and gas seal, the bilateral symmetry of tire transition layer is provided with first nylon and spins cloth film and second nylon and spin the cloth film, and first nylon spins cloth film and second nylon and spins the cloth film and set up in 40~70 mm departments of tire transition layer central line. The utility model discloses simple structure, the design is compact, and first nylon spins the cloth film and spins the effective less department of tire tire shoulder lower part curvature radius that has reduced of setting up of cloth film with second nylon and owing to the tyre cavity bleed -out silk symptom that the local stress inequality causes, reduce the U -shaped of tire in the use and explode, has improved the quality of tire.
Description
Technical field
This utility model relates to a kind of Tire transition layer structure, belongs 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, semi-finished product, the symptom of finished product vaginal bleeding during pregnancy steel wire occurs.The tire of slight bleed-out silk is in use breakneck, easily causes and blows out, 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.Use 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.During molding or sulfuration, inner liner sizing material, transition zone sizing material, carcass by transverse shear stress and are longitudinally upheld.In terms of microcosmic angle, carcass belongs to one-dimensional linear with transition zone, inner liner and contacts.In the case of tension distribution inequality, one-dimensional linear contact easily causes stress and concentrates.Thus, carcass cord position may be moved cause tyre cavity bleed-out silk to transition zone, inner liner.Line opposite is a kind of good stress decentralized model.In the case of 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 carcass, transition zone, the relative position of 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 be prepared as two dimension spin cloth after the functional improvement of its excellence to two-dimensional surface can be suitable for effectively disperseing of local and carcass contact stress.
Summary of the invention
The purpose of this utility model be in order to solve take turns 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, tire shoulder bottom carcass can be disperseed transition zone and the stress of inner liner, reduce the symptom of tyre cavity bleed-out silk.
This utility model 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 40～70 mm.
Further, described first nylon shioze cloth film and the second nylon shioze cloth film are three-decker, be respectively upper film layers and lower film layers, described upper film layers and lower film interlayer 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 0.4～2.5 mm.
Further, the thickness of described first nylon shioze cloth film and the second nylon shioze cloth film is 0.5～3 mm.
Further, the width of described first nylon shioze cloth film and the second nylon shioze cloth film is 100～160 mm.
This utility model simple in construction, 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.

Fig. 2 position top view of the present utility model.
Fig. 3 is the structural representation of the first nylon shioze cloth film of the present utility model.
Reference: Tire transition layer 1, inner liner the 2, first nylon shioze cloth film the 3, second nylon shioze cloth film 4, upper film layers 5, lower film layers 6, nylon shioze layer of cloth 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model 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 40～70 mm, the thickness of the first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 is 0.5～3 mm, the width of the first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 is 100～160 mm, first nylon shioze cloth film 3 and the second nylon shioze cloth film 4 are three-decker, it is respectively upper 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 0.4～2.5 mm.
The one-dimensional linear of local carcass with Tire transition layer 1 and inner liner 2 is contacted the contact changing into line opposite by the first nylon shioze cloth film 3 that Tire transition layer both sides have and the second nylon shioze cloth film 4, is effectively reduced in molding, sulfuration type-approval process tire shoulder position on the lower side due to stress and concentrates the symptom of the tyre cavity bleed-out silk caused.
