Abstract
The utility model discloses a steel cord for an engineering tyre. A cord body is formed by a core wire and fifteen steel wires which are wound outside the core wire in a twisting mode, the core wire is formed by an inner layer core wire and nine outer layer steel wires in a twisting mode, the inner layer core wire is formed by three steel wires in a twisting mode, and twisting directions of the cord body, the core wire and the inner layer core wire are same. The steel cord is strong in bearing capability, puncture-resistance and good in strike-through and abrasion-resistance performance and safety.
Description
Technical field
The utility model relates to the steel cord, relates in particular to the steel cord that uses in a kind of engineering machinery radial.
Background technology
The present 7*7+1 shaped steel cord that uses in the engineering machinery radial is compiled in advance by seven steel wires and to be twisted with the fingers into strand, again strand of internal layer and outer six roots of sensation strand is compiled sth. made by twisting alternately, adds the outer silk that twines at last and forms a cord.Owing to be that mutual the volume twisted with the fingers, be a contact between the steel wire, steel wire easily produces wearing and tearing.7*7+1 shaped steel cord can't satisfy the strength demand of big specification engineering tyre by the mode that increases steel cord arranging density in the cord because cord diameter is bigger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the utility model provides strong, the endurable thorn of a kind of bearing capacity, strike-through and decay resistance and security good engineering tire steel cord.
The utility model is achieved by the following technical solution:
A kind of engineering tire steel cord, described cord body is compiled to twist with the fingers by heart yearn 15 steel wires outer with being wrapped in heart yearn and is formed, described heart yearn is compiled to twist with the fingers with outer nine steel wires by the internal layer heart yearn and is formed, and described internal layer heart yearn is compiled to twist with the fingers by three steel wires and formed, and the sth. made by twisting of described cord body, heart yearn, internal layer heart yearn is to identical.
The sth. made by twisting of described cord body, heart yearn, internal layer heart yearn is twisted with the fingers to being Z-direction.
The lay pitch of described internal layer heart yearn steel wire is that the lay pitch of 6.3mm, heart yearn steel wire is that the lay pitch of 12.5mm, cord body is 18.0mm.
Gauge of wire is 0.225mm in described internal layer heart yearn, heart yearn, the cord body.
The utility model compared with prior art has following beneficial effect:
The utility model adopts as after the above-mentioned technical scheme, and the steel cord is compiled by heart yearn 15 steel wires outer with being wrapped in heart yearn and twisted with the fingers moulding, formed by 27 steel wires altogether, and the intensity height, bearing capacity is big.The cord body, heart yearn, internal layer heart yearn are twist-on-twist, adopt the twist-on-twist structure can avoid that point contacts the wearing and tearing that cause between ordinary lay structure middle level and the layer steel wire, the while also has certain rubber osmosis performance, make between steel wire wearing and tearing still less.Do not have outer wrapping wire and can avoid outer wrapping wire to the wearing and tearing of cover wire, and the minimizing procedure of processing reduces cost.Adopt the characteristics that the high strength material guarantees to have higher intensity, cord diameter is little, reduce the steel cord use amount, improve the anti-fatigue performance of steel cord, can reduce the tire manufacturing cost significantly.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Sequence number among the figure: 1, cord body, 2, heart yearn, 3, the internal layer heart yearn.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
According to shown in Figure 1, a kind of engineering tire steel cord of the utility model, described cord body 1 is compiled to twist with the fingers by heart yearn 2 15 steel wires outer with being wrapped in heart yearn and is formed, described heart yearn 2 is compiled to twist with the fingers with outer nine steel wires by internal layer heart yearn 3 and is formed, described internal layer heart yearn 3 is compiled to twist with the fingers by three steel wires and is formed, described cord body 1, heart yearn 2, the sth. made by twisting of internal layer heart yearn 3 is twisted with the fingers to the identical Z-direction that is, the lay pitch of described internal layer heart yearn 3 steel wires is 6.3mm, the lay pitch of heart yearn 2 steel wires is 12.5mm, the lay pitch of cord body 1 is 18.0mm, described internal layer heart yearn 3, heart yearn 2, gauge of wire is 0.225mm in the cord body 1.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not constitute 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 all still belongs within the utility model protection domain.
