Abstract
The utility model discloses a steel cord used for a tubeless all-steel truck radial tire body. The steel cord is formed by steel wires in a weaving and entwisting mode. The six inner layer steel wires are woven and entwisted around one core wire to be a center strand, and then the twelve outer layer steel wires are evenly arranged around the center strand to form the steel cord in the weaving and entwisting mode. The section of the steel cord is round. The steel cord is high in strength, small in diameter of the steel wires, good in bending loading performance, flexibility, fatigue resistance and corrosion resistance, capable of reducing the weight of a tire, and low in heat build-up, consumes little oil, and saves production resources and production cost.
Description
Technical field
The utility model relates to the all-steel cord that in the tubeless all-steel load-bearing radial tire, carcass is used.
Background technology
In recent years, China's radial development is very fast, particularly the heavy load radial tire development is more swift and violent, China has become the maximum heavy load radial tire producing country in the whole world, but for a long time, the development of China's radial heavy duty tire only is confined to the tubed tyre aspect, and tubeless tyre output accounts for the ratio less than 40% of total output, and most of products export.Domestic except some luxurious bus assembling tubeless tyres, most commercial car still rest on the inner tube tyre stage that is equipped with.Tubeless tyre will be one of important content of China's tire product structural adjustment from now on, and high-capacity tyre is the most at last to the tubeless development, replace market tubeless demand progressively to increase China's tubeless tyre development will be a huge promotion.
Meridian, without internalization, flattening, be the developing direction of all-steel radial tire, developed country's meridian such as American-European, Japanese, without internalization, reached more than 90%, low section all steel tubeless ABRASION RESISTANCE, handling safety and the low-rolling-resistance fuel-economizing excellent with it just becoming its main product.Tubeless high-end market foreign capitals brand has certain quality heterosis, especially driving wheel and top grade block passenger tyre, the foreign brand names such as the BS of Michelin are occupied leading position, and its outstanding feature is that wear hardness is excellent, refresh rate is high, long therefore traction is high the Brand Breeding time in addition for technique accordance height.Therefore, development and Design has low section all steel tubeless independent intellectual property right, the properties excellence, 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, steel wire diameter is little, the bend loading of cord, pliability, endurance and corrosion resistance and good, can alleviate tire weight, heat-dissipating is low, oil consumption is few, saves a kind of tubeless all-steel load-bearing radial tire carcass all-steel cord of the resources of production and production cost.
The utility model is achieved by the following technical solution:
A kind of tubeless all-steel load-bearing radial tire carcass all-steel cord, compiled to twist with the fingers by steel wire and form, after it forms central strand by six roots of sensation steel wire of internal layer around a heart yearn volume sth. made by twisting, then around evenly being arranged in central strand by 12 cover wires, the volume sth. made by twisting forms, and Formation cross-section is circular all-steel cord.
The sth. made by twisting of described cover wire and steel wire of internal layer is to identical, for Z twists with the fingers.
The lay pitch of described cover wire and steel wire of internal layer is respectively 16.0mm and 6.3mm.
The diameter of described cover wire is 0.20mm, and the diameter of steel wire of internal layer is 0.22mm, and the diameter of heart yearn is 0.25mm.
The utility model compared with prior art has following beneficial effect:
The utility model adopts high-tensile steel wires to compile and twists with the fingers, and steel wire diameter is little, and the bend loading of cord, pliability and fatigue durability are high; Heart yearn, steel wire of internal layer, cover wire diameter sequentially successively decrease, and the gap between steel wire increases, and can effectively guarantee the infiltration of sizing material; Between steel wire, twisting with the fingers to identical, is the line contact, and contact area is large, and contact is little, can effectively reduce the abrasion between steel wire.This structure can be in the situation that guarantee carcass intensity, the thickness of minimizing cord.The tire weight of making is light, and heat-dissipating is low, and oil consumption is few, saves the resources of production and production cost.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
Sequence number in figure: 1, cover wire, 2, steel wire of internal layer, 3, heart yearn, 4, central strand.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, a kind of tubeless all-steel load-bearing radial tire of the utility model carcass all-steel cord, after it is twisted central strand 4 by six roots of sensation steel wire of internal layer 2 around a heart yearn 3 volumes, around evenly being arranged in central strand 4 by 12 cover wires 1 again, the volume sth. made by twisting forms, and Formation cross-section is circular all-steel cord; The sth. made by twisting of described cover wire 1 and steel wire of internal layer 2 is to identical, for Z twists with the fingers; The lay pitch of described cover wire 1 and steel wire of internal layer 2 is respectively 16.0mm and 6.3mm; The diameter of described cover wire 1 is 0.20mm, and the diameter of steel wire of internal layer 2 is 0.22mm, and the diameter of heart yearn 3 is 0.25mm.
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.
