Abstract
The utility model discloses an eleven-strand steel cord for a heavy truck tire. The eleven-strand steel cord comprises an inner-layer core wire group and an outer-layer core layer group, wherein the inner-layer core wire group is formed by weaving and twisting three inner-layer core wires (1) arranged in a regular triangle; the outer-layer core wire group is formed by weaving and twisting eight outer-layer core wires (2) which uniformly encircle the inner-layer core wire group; and the inner-layer core wire group and the outer-layer core wire group are woven and twisted in the same direction to form the steel cord with a round section. The eleven-strand steel cord has high plastic infiltration performance and corrosion resistance, and has puncture resistance and high rigidity.
Description
Technical field
The utility model relates to ten one steel cords that use in a kind of heavy card truck tyre.
Background technology
Heavily use 3+6 shaped steel cord in the truck at present; Be made up of three heart yearns of internal layer and outer six roots of sensation monofilament, the cord ordinary lay is a contact between the steel wire; Six roots of sensation monofilament dense arrangement is around heart yearn; Almost very close to each other between the monofilament, make rubber be difficult to penetrate in the steel cord, cause that the bonding force of steel cord and rubber descends.And, have the space in the monofilament of steel cord because rubber can not fully be penetrated in the steel cord, and water conservancy diversion moisture is played in these spaces or salt penetration advances in the steel cord, and when tire during by deflection repeatedly, the steel cord maybe accelerated corrosion, the service life of reducing tire.
Summary of the invention
The utility model provides ten one steel cords that use in a kind of heavy card truck tyre, and not only the strike-through performance is good for it, and the corrosion resistance ability is strong, and puncture, rigidity are high.
The utility model has adopted following technical scheme: ten one steel cords that use in a kind of heavy card truck tyre; It comprises internal layer heart yearn group and outer heart yearn group; Internal layer heart yearn group is compiled to twist with the fingers by three internal layer heart yearns and is formed, and three internal layer heart yearns are equilateral triangle to be arranged, and outer heart yearn group is compiled to twist with the fingers by eight outer heart yearns and formed; Eight outer heart yearns evenly be centered around internal layer heart yearn group around, internal layer heart yearn group and outer heart yearn group are done to compile in the same way and are twisted with the fingers the back and form the steel cord that the cross section be a circle.
The sth. made by twisting of described internal layer heart yearn is to being the S sth. made by twisting, and the lay pitch of internal layer heart yearn is 18.0mm.The sth. made by twisting of described outer heart yearn is to being the S sth. made by twisting, and the lay pitch of outer heart yearn is 18.0mm.The diameter of described internal layer heart yearn is 0.35 mm.The diameter of described outer heart yearn is 0.35 mm.
The utlity model has following beneficial effect: the outer heart yearn group of the utility model is compiled to twist with the fingers by eight outer heart yearns and is formed; Its diameter is greater than employed filament diameter in the 3+6 shaped steel cord; But also correspondingly two monofilament have been increased; Improved the mechanical property of steel cord like this, guaranteed that heavily blocking truck tyre reaches corresponding bearing capacity.Eight outer heart yearns of the utility model not exclusively wrap up the heart yearn of centre; Can leave more gap like this; Be convenient to the infiltration of rubber; Help improving the bonding force between rubber and the steel cord, thereby avoid causing corrosion because of moisture (moisture) enters into steel cord inside, the infiltration of sizing material simultaneously can limit relatively moving between steel wire effectively and reduce to wear and tear between steel wire.The utility model also has superior function such as impact resistance, puncture preferably in addition.It is an one-step shaping, and therefore the production cost of this steel cord can significantly reduce, and increases economic efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In Fig. 1, the utility model is ten one steel cords that use in a kind of heavy card truck tyre, and it comprises internal layer heart yearn group and outer heart yearn group; Internal layer heart yearn group is compiled to twist with the fingers by three internal layer heart yearns 1 and is formed, and the diameter of internal layer heart yearn 1 is 0.35 mm, and the sth. made by twisting of internal layer heart yearn 1 is to twisting with the fingers for S; The lay pitch of internal layer heart yearn 1 is 18.0mm; Three internal layer heart yearns 1 are equilateral triangle to be arranged, and outer heart yearn group is compiled to twist with the fingers by eight outer heart yearns 2 and formed, and the diameter of outer heart yearn 2 is 0.35 mm; The sth. made by twisting of outer heart yearn 2 is to twisting with the fingers for S; The lay pitch of outer heart yearn 2 is 18.0mm, eight outer heart yearns 2 evenly be centered around internal layer heart yearn group around, internal layer heart yearn group and outer heart yearn group are done to compile in the same way and are twisted with the fingers the back and form the steel cord that the cross section is a circle.
