Abstract
The utility model discloses a steel cord for a truck tire. The utility model is composed of a cord body and externally winded steel wires winded outside the cord body. The section of the cord body is a regular hexagon; and is composed of seven twisted steel wire strands with circular sections; each steel wire strand is composed of 27 twisted wires. The steel cord body and the externally- winded steel wires are twisted together. The utility model which is composed of 189 wires is simple in structure, strong in bearing capability and applicable for huge tires of large-scale engineering vehicles.
Description
Technical field
The utility model relates to a kind of high-capacity tyre steel cord.
Background technology
Along with developing rapidly of highway, the performance requirement of tire is also improving constantly, require the carcass of engineering bogie radial to have corresponding bearing capacity and resistance to persistence energy, pneumatic tire has been proposed requirements at the higher level with the steel cord, must improve the load-carrying properties of steel cord.
Summary of the invention
The utility model provides a kind of high-capacity tyre steel cord, its Stability Analysis of Structures, and bearing capacity is strong, and the giant embryo that is suitable for the heavy construction car uses.
The technical solution of the utility model is as follows: a kind of high-capacity tyre steel cord, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, described cord body section is regular hexagon, it is compiled to twist with the fingers by seven rounded steel strands in cross section and forms, every steel strand is compiled to twist with the fingers by 27 monofilament and is formed, and described cord body is an ordinary lay with outer winding steel wire.
Described steel strand is by nexine, intermediate layer and outer the composition, and described nexine is compiled to twist with the fingers by three monofilament and formed; Described intermediate layer is compiled to twist with the fingers by nine monofilament and is formed, and twists with the fingers to identical with nexine; Described skin is compiled to twist with the fingers by 15 monofilament and is formed, and twists with the fingers to identical with the intermediate layer.
The described outer diameter that twines silk is 0.15-0.25mm, twist with the fingers to be Z to, the lay pitch is 5mm; The nexine filament diameter is 0.175-0.245mm, and the lay pitch is 5-6.3mm; Described intermediate layer filament diameter is 0.175-0.245mm, and the lay pitch is 10-12.5mm; Described outer filament diameter is 0.175-0.245mm, and the lay pitch is 16-18mm.
After adopting as above technical scheme, the cord body is compiled to twist with the fingers by seven steel strands and is formed, and every steel strand is made up of 27 monofilament, has 189 monofilament, the intensity height, and bearing capacity is strong, is suitable for the giant tyre use.The steel strand cross section is rounded, and the cord body section is a regular hexagon, and both are regular shape in the cross section, and the cord body structure is stable, and security performance is good.The outer winding between silk, steel strand, the intermediate layer monofilament is ordinary lay, easy each other strike-through, and rubber can fully be penetrated in the steel cord, and corrosion resistance is strong, has prolonged the service life of tire.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model high-capacity tyre with the steel cord
The specific embodiment
According to shown in Figure 1, a kind of high-capacity tyre of the utility model steel cord, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, described cord body section is regular hexagon, it is compiled to twist with the fingers by the rounded steel strands in seven cross sections and forms, sth. made by twisting to be S to, the lay pitch is 38-48mm.The described outer diameter that twines silk is 0.15-0.25mm, twist with the fingers to be Z to, the lay pitch is 5mm.
Every steel strand is compiled to twist with the fingers by 27 monofilament and is formed, and it is by nexine, intermediate layer and outer the composition, and described nexine is compiled sth. made by twisting by three monofilament and formed, and the nexine filament diameter is 0.175-0.245mm, sth. made by twisting to be S to, the lay pitch is 5-6.3mm; Described intermediate layer is compiled to twist with the fingers by nine monofilament and is formed, twist with the fingers to identical with nexine be S to, filament diameter is 0.175-0.245mm, the lay pitch is 10-12.5mm; Described skin is compiled to twist with the fingers by 15 monofilament and is formed, and filament diameter is 0.175-0.245mm, and the lay pitch is 16-18mm, twist with the fingers to the intermediate layer be all mutually S to.
