Abstract
The utility model discloses an all-steel cord for a belt layer of a radial tire. The all-steel cord is formed by steel wires in a woven and entwisted mode. The all-steel cord is formed by three steel wire core wires and eight outer-layer steel wires in a once woven and entwisted mode, wherein the eight out-layer steel wires are evenly arranged on the peripheries of the steel wire core wires. The entwisting distances of the steel wire core wires are 10.0mm, the entwisting distances of the outer-layer steel wires are 20.0mm, the all-steel core with the circular cross section is formed, and the cross sections of the three steel wire core wires are arranged in a triangular mode. The all-steel cord is high in strength, simple in structure, good in glue seeping performance, high in corrosion resistance, impalement resistant, light in dead load and low in cost.
Description
Technical field
The utility model relates to the all-steel cord that in all-steel load-bearing radial tire, band bundled layer is used.
Background technology
In radial, band bundled layer has born the stress of tyre load more than 60% as main stressed member.In current domestic tire, the 3+9+15+1 shaped steel wire cords that use as the band bundled layer framework material more, and its rupture strength is high, pliability good, but, due to complex structure, machining process route is long, and production efficiency is low, and use cost is high; Because its line density is larger, the tire deadweight is increased simultaneously.Therefore, development and Design has the all-steel cord that Pneumatic tire carcass independent intellectual property right, the properties excellence is used, and adjusts enterprise product structure or long-term national tire industry development all seems particularly important.
Summary of the invention
The purpose of this utility model is to provide that a kind of intensity is high, simple in structure, the strike-through performance is good, corrosion resistance is strong, puncture-resistant, low deadweight, radial tire undertread all-steel cord cheaply.
The utility model is achieved by the following technical solution:
The radial tire undertread all-steel cord, compiled to twist with the fingers by steel wire and form, it is by three wire cored wires and evenly be arranged in eight cover wires around wire cored wire and once compile to twist with the fingers and form, the lay pitch of wire cored wire is 10.0mm, the lay pitch of cover wire is 20.0mm, Formation cross-section is circular all-steel cord, and the cross section of three wire cored wires is equilateral triangle and arranges.
Described three wire cored wires and the sth. made by twisting that evenly is arranged in eight cover wires around wire cored wire, to identical, are that S twists with the fingers.
The diameter of described wire cored wire and cover wire is identical, is 0.33mm.
The utility model compared with prior art has following beneficial effect:
The utility model evenly is arranged in cover wire around heart yearn by three heart yearn steel wires and eight and makes identical sth. made by twisting and compile and twist with the fingers to, the different lay pitch, adopt eight high-tensile steel wires, can significantly improve the mechanical property of all-steel cord, make tire and can meet or exceed corresponding bearing capacity; Cover wire can not wrap up fully to middle wire cored wire, make between steel wire to leave more gap, be convenient to the infiltration of rubber, be conducive to improve the bonding force between rubber and all-steel cord, thereby avoid causing corrosion because moisture enters into all-steel cord inside, the infiltration of sizing material simultaneously can limit relatively moving between steel wire effectively, reduces to wear and tear between steel wire; It uses the one-step shaping method to produce, and can reduce the production cost of all-steel cord, and the high strength steel filament diameter is little simultaneously, and the glue thickness that covers of cord is minimized, and reduces the consumption of sizing material, increases economic efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
Sequence number in figure: 1, wire cored wire, 2, cover wire.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, the utility model one meridian tyre belted layer all-steel cord, it is by three wire cored wires 1 and evenly be arranged in eight cover wires 2 around wire cored wire 1 and once compile in the same way to twist with the fingers and form, sth. made by twisting is to twisting with the fingers for S, the lay pitch of wire cored wire 1 is 10.0mm, the lay pitch of cover wire 2 is 20.0mm, and Formation cross-section is circular all-steel cord, and the cross section of three wire cored wires is equilateral triangle and arranges; Described wire cored wire 1 is identical with the diameter of cover wire 2, is 0.33mm.
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.
