Abstract
The utility model discloses a ten-strand steel cord for a belted layer in a pneumatic tire. The ten-strand steel cord is formed by weaving and twisting steel wires, in detail, the ten-strand steel cord is formed by weaving and twisting six steel wires on the outer layer around an inner layer core wire, the six steel wires on the outer layer does not wrap the inner layer core wire completely, the inner layer core wire is formed by four steel wire bodies distributed in a rhombus mode, the twisting direction of the six steel wires on the outer layer around the inner layer core wire is S-twist, and the lay length is 22.0mm. The steel cored is high in strength, good in glue permeation performance, strong in anti-corrosion performance, stabbing-resistance and capable of reducing the weight of the tire and saving manufacturing cost of the tire.
Description
Technical field
The utility model relates to the steel cord that in pneumatic tire, band bundled layer is used, and relates in particular to the high strength steel cord used in a kind of underloading truck and car.
Background technology
Use the 3+6 steel cord in underloading truck and car at present, by three heart yearns of internal layer and outer six roots of sensation heart yearn, formed, six roots of sensation heart yearn dense arrangement is around the internal layer heart yearn, almost very close to each other between internal layer heart yearn and outer heart yearn, make rubber be difficult to penetrate in the steel cord, cause that the bonding force of steel cord and rubber descends.And, because rubber can not fully be penetrated in the steel cord, in the monofilament of steel cord, space may be arranged, 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 may accelerated corrosion, the service life of reducing tire.Chinese patent CN201120291355.2 discloses seven strands of steel cords that in a kind of pneumatic tire, band bundled layer is used, 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 two internal layer heart yearns and is formed, the arrangement of being rectangle of two internal layer heart yearns, outer heart yearn group is compiled to twist with the fingers by five outer heart yearns and is formed, five outer heart yearns be distributed in two internal layer heart yearns around do to compile in the same way that to twist with the fingers Formation cross-section be oval-shaped steel cord, have equally above-mentioned technological deficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of intensity is high, the strike-through performance is good, the corrosion resistance ability is strong, puncture-resistant, can alleviate tire weight, save ten strands of steel cords for a kind of pneumatic tire band bundled layer of the manufacturing cost of tire.
The utility model is achieved by the following technical solution:
Ten strands of steel cords for band bundled layer in a kind of pneumatic tire, compiled to twist with the fingers by steel wire and form, it compile to be twisted with the fingers and to form around the internal layer heart yearn by outer six roots of sensation steel wire, and described outer six roots of sensation steel wire not exclusively wraps up the internal layer heart yearn, and described internal layer heart yearn is the arrangements that assume diamond in shape of four steel wires; Described outer six roots of sensation steel wire is around the sth. made by twisting of internal layer heart yearn to being that S twists with the fingers, and the lay pitch is 22.0mm.
Non-twist distance between described internal layer heart yearn steel wire.
The steel wire diameter of described outer six roots of sensation steel wire and internal layer heart yearn is all 0.38mm.
The utility model compared with prior art has following beneficial effect:
The outer six roots of sensation steel wire of the utility model and internal layer heart yearn all adopt the same diameter steel wire, filament diameter 0.38mm, the lay pitch is 22.0mm, outer six roots of sensation steel wire not exclusively wraps up the internal layer heart yearn, leave more gap, be convenient to the infiltration of rubber, be conducive to improve the bonding force between rubber and steel cord, thereby avoid causing corrosion because moisture enters into steel cord inside; It also has the superior function such as impact resistance, puncture-resistant preferably; The outer monofilament six roots of sensation that adopts, the internal layer heart yearn is the arrangements that assume diamond in shape of four steel wires, the production cost of this steel cord can significantly reduce, and increases economic efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
Sequence number in figure: 1, outer six roots of sensation steel wire, 2, the internal layer heart yearn.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, ten strands of steel cords for band bundled layer in a kind of pneumatic tire of the utility model, it is compiled to twist with the fingers around internal layer heart yearn 2 by outer six roots of sensation steel wire 1 and forms, 1 pair of internal layer heart yearn 2 of described outer six roots of sensation steel wire not exclusively wraps up, described internal layer heart yearn 2 is the arrangements that assume diamond in shape of four steel wires, and described outer six roots of sensation steel wire 1 is around the sth. made by twisting of internal layer heart yearn 2 to being that S twists with the fingers; Non-twist distance between described internal layer heart yearn 2 steel wires; The steel wire diameter of described outer six roots of sensation steel wire 1 and internal layer heart yearn 2 is all 0.38mm; It is 22.0mm that described outer six roots of sensation steel wire 1 is compiled the lay pitch of twisting with the fingers around internal layer heart yearn 2.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model, above scheme being done that does not break away from technical solutions of the utility model, within all still belonging to the utility model protection domain.
