The present invention proposes a kind of superhigh intensity steel cord of (3+6) structure, including the heart yearn that internal layer is constituted in three heart yearn steel wires of equilateral triangle arrangement, outer layer six roots of sensation steel wire is compiled around three heart yearn steel wires of internal layer and is twisted type, Formation cross-section is circular steel cord, the sth. made by twisting of the internal layer heart yearn is twisted with the fingers to for S, and the sth. made by twisting of cover wire is twisted with the fingers to for Z；Internal layer heart yearn is directly less than cover wire diameter, and internal layer heart yearn compiles the lay pitch twisted with the fingers and the lay pitch twisted with the fingers is compiled less than cover wire.Steel cord of the invention uses extra-high strength wire, and steel wire diameter is small, and the bend loading of cord, pliability and fatigue performance are also accordingly improved；This structure in the case where carcass intensity is ensured, can reduce the thickness of cord, and the tire weight being made is light, and heat is low, and oil consumption is few, saves the resources of production and production cost, adapts to green, the growth requirement of high-performance tire.
Description
Technical field
The present invention relates to steel cord for tire technical field, more particularly to intensity is high, lightweight one kind (3+6) structure
Superhigh intensity steel cord.
Background technology
In modern society's life, people are increasing to the demand of automobile industry, and this has just driven the rapid of tire industry
Development, also proposes higher and higher requirement to tire enterprise, and it is general trend of events institute to continually develop high-performance, the tire product of low cost
Become.As steel cord for tire, not only tire can be made to possess the performances such as excellent impact resistance, puncture-resistant, also examined in addition
Consider the cost of steel cord production cost in itself and tire；The weight of tire is also reduced as far as possible, reduce the fuel consumption of vehicle,
To meet requirement of the current social to green product.Therefore, steel cord is carried out using the steel wire of the thinner superhigh intensity of diameter
Production is just into the trend of steel cord development.
The content of the invention
In view of the demand in existing use, it is an object of the invention to provide a kind of superhigh intensity steel cord of (3+6) structure,
The lightweight of tire can be conducive to, and with superior intensity and endurance, impact resistance.
To achieve the object of the present invention, a kind of superhigh intensity steel cord of (3+6) structure of the invention, including internal layer is in
The heart yearn that three heart yearn steel wires 10 of equilateral triangle arrangement are constituted, outer layer six roots of sensation steel wire 20 is compiled around three heart yearn steel wires of internal layer
Type is twisted, Formation cross-section is circular steel cord, and the sth. made by twisting of the internal layer heart yearn is twisted with the fingers to for S, and the sth. made by twisting of cover wire is twisted with the fingers to for Z；It is interior
Layer heart yearn is directly less than cover wire diameter, and internal layer heart yearn compiles the lay pitch twisted with the fingers and the lay pitch twisted with the fingers is compiled less than cover wire；Described core
Line steel wire and cover wire are extra-high strength wire.
Preferably, described internal layer core line diameter is 0.175mm, a diameter of 0.32mm of cover wire.
Further preferably, it is 9.5mm that described internal layer heart yearn compiles the lay pitch twisted with the fingers, and it is 15.5mm that cover wire compiles the lay pitch twisted with the fingers.
Steel cord of the invention uses extra-high strength wire, and steel wire diameter is small, the bend loading of cord, pliability and resistance to tired
Labor performance is also accordingly improved；This structure in the case where carcass intensity is ensured, can reduce the thickness of cord, the wheel being made
Tire is lightweight, and heat is low, and oil consumption is few, saves the resources of production and production cost, adapts to green, the growth requirement of high-performance tire.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the present invention is foregoing will to be become with other objects, features and advantages
Obviously.Wherein：
Fig. 1 show the structural representation of the superhigh intensity steel cord of one kind (3+6) structure of the invention；
Fig. 2 show the lay pitch schematic diagram of the steel cord of Fig. 1.
Specific embodiment
Shown in reference picture 1 and Fig. 2, the superhigh intensity steel cord of one kind (3+6) structure of the invention, including internal layer is in positive three
The heart yearn that three heart yearn steel wires 10 of triangular arrangement are constituted, outer layer six roots of sensation steel wire 20 is compiled around three heart yearn steel wires of internal layer and is twisted
Type, Formation cross-section is circular steel cord, and the sth. made by twisting of the internal layer heart yearn is twisted with the fingers to for S, and the sth. made by twisting of cover wire is twisted with the fingers to for Z；Internal layer core
Line is directly less than cover wire diameter, and internal layer heart yearn compiles the lay pitch twisted with the fingers and the lay pitch twisted with the fingers is compiled less than cover wire；Described heart yearn steel
Silk and cover wire are extra-high strength wire.One preferred embodiment in, the internal layer core line diameter be 0.175mm,
The a diameter of 0.32mm of cover wire.
When steel cord carries out twisting, due to having used the unimach silk cord of small diameter, therefore, during twisting
The lay pitch, the sth. made by twisting of different layers steel cord to etc. be required for being redesigned accordingly.The lay pitch is big, and productivity ratio is high, but fatigue durability
Can decline, this is because when the lay pitch is bigger, the torsional deflection degree of cord monofilament in twisting is with regard to smaller, its elastic restoring force
It is larger, if this elastic restoring force cannot be eliminated, can decline the fatigue performance of cord, service life shortens；The lay pitch
Small, the fatigue performance of steel cord improves, and elongation is high, but the spinning loss of intensity is big, and productivity ratio is also reduced.So according to not
It is the importance in steel cord R＆D process to carry out rational lay pitch design with the all-steel cord and different steel wire diameters of intensity
Can parameter.In addition, arrangement of the steel cord in twisting is the cross sectional shape of internal layer cord and outer layer cord for its strike-through
Performance has important influence, is also important Consideration.The application one preferred embodiment in, described is interior
It is 9.5mm that layer heart yearn compiles the lay pitch twisted with the fingers, and it is 15.5mm that cover wire compiles the lay pitch twisted with the fingers.
Steel cord of the invention is used according to newest《Radial steel cord》National standard (GB/T_
11181-2016) the extra-high strength wire of regulation, the intensity of steel wire than the regular tenacity of same diameter improves 20% or so；Steel wire
Diameter is small, and the bend loading of cord, pliability and fatigue performance are also accordingly improved.It is linear contact lay, contact area between steel wire
Greatly, contact is small, is effectively reduced the abrasion between steel wire.This structure can ensure carcass intensity in the case of,
The thickness of cord is reduced, the tire weight being made is light, and heat is low, and oil consumption is few, saves the resources of production and production cost, adapts to green
The growth requirement of color, high-performance tire.
The invention is not limited in described embodiment, those skilled in the art is not departing from spirit of the invention i.e. public affairs
In the range of opening, can still make some amendments or change, thus the scope that is limited with claims of the scope of the present invention as
It is accurate.
