The diameter of cover wire 3 is 0.20mm.The present invention is made up by the structure of change all-steel cord because steel cord structure designs
Unreasonable bring defect, and then improve the fatigue performance of 3/9/15 × 0.20 structure radial all-steel cord and resist
Impact property reduces the air content inside tire all-steel cord, improves cotton tyre cord strength grade, avoids radial
Because the problem of cord bearing capacity failure occurs in the abrasion of each layer steel wire point contact in use process.
The orientation of core wire steel wire 1, the orientation of wire of intermediate layer 2, the orientation of cover wire 3 are identical, of the invention preferred
In embodiment, it is that Z is twisted that core wire steel wire 1, wire of intermediate layer 2 and cover wire 3, which compile the orientation twisted,；Core wire steel wire 1 compiles the twirl twisted
Away from D1, wire of intermediate layer 2 compile twist lay pitch D2, cover wire 3 compile twist lay pitch D3It is identical, in a preferred embodiment of the invention,
Core wire steel wire 1, wire of intermediate layer 2 and cover wire 3 compile the lay pitch D twisted1、D2、D3It is identical, and be 12.5-20.0mm, more preferably
Ground, it is 16.0mm that core wire steel wire 1, wire of intermediate layer 2 and cover wire 3, which compile the lay pitch twisted,.Core wire steel wire 1, wire of intermediate layer 2
Orientation identical as 3 use of cover wire, and by the lay pitch D of core wire steel wire 11With the lay pitch D of wire of intermediate layer 22Improve to and outer layer
The lay pitch D of steel wire 33It is identical, the contact area between each layer steel wire is increased, is reduced between 100 each layers of steel wire of all-steel cord
Point contact friction, can prevent tire used process because intensity of steel wire is insufficient or steel wire corrosion with abrasion caused by cord hold
The problem of loading capability fails, having improves the anticorrosive of radial, endurance and shock resistance and bonding retentivity, mentions
The beneficial effect of the service life of high tire.
As the preferred embodiment of the present invention, core wire steel wire 1, wire of intermediate layer 2, cover wire 3 strength grade be it is general
Logical intensity NT, high intensity HT, superhigh intensity ST or Extra High Strength UT.The present invention is suitable for regular tenacity NT, high intensity HT, surpasses
High-intensitive ST, Extra High Strength UT different intensity grades steel wire carry out volume twirl, can be improved compile twist formed all-steel cord it is resistance to
Fatigue behaviour and shock resistance.
Fig. 3 and table 1 are referred to, Fig. 3 is that a kind of structure of the all-steel cord of the structure of 3+9+15 × 0.225 of the prior art is shown
It is intended to, table 1 is existing radial common 3+9+15 × 0.225 HT structure all-steel cord and one embodiment of the invention
