Abstract
The utility model provides an ultrahigh strength steel cord for tire belt layer which characterized in that forms the transversal ellipse form of personally submitting of cord by seven outer layer wire around two inner steel wire twisting, interior outer layer wire intensity is 3300~3800MPa. The utility model is used for tire belt layer, it is good to have the strike -through performance, characteristics such as corrosion -resistant ability reinforce to make the tire have the good nature controlled and drive the travelling comfort.
Description
Technical field
This utility model relates to steel cord, particularly to a kind of unimach cord for tire belt.
Background technology
In the modern life and production, people are increasing to the demand of automobile, bogie industry, this has just driven developing rapidly of tire industry, and tire enterprise also proposes increasingly higher requirement, and the endurance quality of tire, speed ability, security performance and refresh rate improve constantly.Belt is the critical component of all-steel load-bearing radial tire, bears the load of tire about more than 60%, and its framework material performance is one of key factor determining tire combination property.Belt focuses on the performances such as rubber osmosis performance, rigidity, bond properties, tensile strength, decay resistance, anti-compression properties, shock resistance and dimensionally stable with all-steel cord.
Existing steel cord mostly is circular configuration, its strike-through poor-performing, and then reduces its anticorrosive and anti-fatigue performance；It addition, under competitive pressure, cost efficiency is also the requisite measure of tire enterprise seeking development in the market, the saving of limited resources uses and is also brought into schedule by manufacturing industry.Therefore, the challenge of performance, cost and energy conservation is constantly accepted as the all-steel cord of tyre framework material, in addition energy-saving and emission-reduction are increasingly paid attention to all over the world at present, high-performance, low-energy-efficiency tire development can be increasingly faster, the strength demand of steel cord is required by tire also can be more and more higher, therefore reduces steel wire filament diameter, improving filament strength is trend of the times, but, what the reduction of steel wire diameter brought is the reduction of cord rigidity, thus affecting the tire operability to complex road condition.
Summary of the invention
The purpose of this utility model is in that to provide a kind of unimach cord for tire belt, the features such as it is good that it has strike-through, and corrosion resistance is strong, and makes tire have the features such as good handling, driver comfort.
For reaching above-mentioned purpose, the technical solution of the utility model is:
A kind of unimach cord for tire belt, it is characterised in that formed around two steel wire of internal layer twisting by seven cover wires, cord cross section oval in shape；Described ectonexine intensity of steel wire is 3300～3800MPa.
Preferably, described ectonexine steel wire diameter is identical, is 0.20～0.35mm.
Preferably, the described steel wire of internal layer lay pitch is 25～35 times of steel wire diameter, and the cover wire lay pitch is 2 times of the steel wire of internal layer lay pitch.
Preferably, described ectonexine steel wire is twisted with the fingers to identical.
This utility model compared with prior art has the advantage that
1. this utility model internal layer is two steel wires, internal layer is irregular, it is fully wrapped around that seven steel wires of outer layer can not realize internal layer, there is between outer layer and internal layer more gap, this structure not only makes rubber fully can be permeated by this gap, and can internal layer and internal layer monofilament well be embedded, and rubber penetrates into performance and is greatly improved, effectively raising the bonding force between steel cord and rubber, steel cord structural stability in tire and anchoring are also greatly improved.Simultaneously because this structure makes rubber can be fully infiltrated in the hole of steel cord, thus avoid the intrusion of steam.Improve corrosion resistance and the Using Life of Tyre of cord, strengthen steel cord adhesion retention.
2. there is the steel cord of oval cross section, have an advantage in that: rigidity is more than the steel cord that cross section is circle, and there is different rigidity on the different directions of oval steel cord, this feature makes tire have well handling and driver comfort when determining this utility model for tire belt.On the direction vertical with the major axis of oval steel cable, its rigidity reduces and flexible increase such that it is able to be easy to accept different road conditions.On the long axis direction of oval steel cable, its rigidity increases and flexible reduction, thus causing that stability is better when bending.
3. the selection of this utility model lay pitch is based on cord production efficiency and becomes rope quality consideration, and the lay pitch is too little, and production efficiency is low, the lay pitch is too big, cord is easily loose, becomes rope of poor quality, and the outer layer lay pitch is that the cord that the twice of the internal layer lay pitch then makes has good uniformity in length.
4. this utility model is unimach cord, can significantly reduce cord and make consumption and tire overall weight, energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of this utility model steel cord one embodiment.
Detailed description of the invention
Referring to Fig. 1, a kind of unimach cord for tire belt of the present utility model, being formed around two steel wire of internal layer 2 twisting by seven cover wires 1, cord cross section oval in shape, ectonexine steel wire diameter is identical, filament diameter is 0.20～0.35mm, the internal layer lay pitch is 25-35 times of steel wire diameter, and the outer layer lay pitch is 2 times of the internal layer lay pitch, and ectonexine is twisted with the fingers to identical, intensity of steel wire is superhigh intensity, and strength range is 3300-3800MPa.
Embodiment
Monofilament be drawn through overdrying by the wire rod of carbon content to be 0.86wt% diameter be 5.5mm, heat treatment, plating, wet the operation such as draw after be drawn into the steel wire that diameter is 0.30mm, its monofilament tensile strength is 3570MPa.
Seven diameters are the steel wire 1 of 0.30mm is that 0.30mm steel wire of internal layer 2 forms with " S sth. made by twisting " twisting around two diameters, and its outer layer lay pitch 16mm, the internal layer lay pitch is 8mm, and cord cross section be ellipse.
Above-mentioned cord structure is simple, main product 4+6 × 0.30HT for substituting current strike-through performance good is used in tire belt, not only the intensity of cord own increases, and strike-through performance has reached the level of full strike-through equally, additionally it is significantly increased in tire resisting fatigue, and improves cord intensity, significantly reduce cord weight, reduce production cost, increase economic efficiency, it is achieved the lightweight requirements of tire.
