Abstract
The utility model discloses a steel cord for an engineering tire. The steel cord is composed of a cord body and an outer winding steel wire wound on the outside of the cord body. The cord body and the outer winding steel wire are twisted in different directions. The cord body is formed through twisting of a core line (1) and six steel wire strands (2) wound on the outside of the core line (1). The core line (1) is formed through the twisting of three inner layer steel wires, nine middle steel wires and fifteen outer layer steel wires in the same direction, and each steel wire strand (2) is formed through the twisting of three inner layer steel wires, nine middle steel wires and fifteen outer layer steel wires in the same direction.
Description
Technical field
The utility model relates to a kind of engineering tire steel cord.
Background technology
It is little that present engineering tire exists intensity with the steel cord, and bearing capacity is little.Be the face contact between the steel wire thigh, so transportable space is little and flexible poor between each layer monofilament, fatigue performance is poor, and service life is shorter.
Summary of the invention
The utility model provides a kind of engineering tire steel cord, and not only bearing capacity is strong for it, and endurable thorn, anti-strike-through, decay resistance and security are good.
The utility model has adopted following technical scheme: a kind of engineering tire steel cord, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, be ordinary lay between cord body and the outer winding steel wire, described cord body is compiled to twist with the fingers by the heart yearn six roots of sensation steel strand outer with being wrapped in heart yearn and is formed, described heart yearn is compiled in the same way to twist with the fingers by three steel wire of internal layer, nine process wires and 15 cover wires and is formed, and described every steel strand is compiled in the same way to twist with the fingers by three steel wire of internal layer, nine process wires and 15 cover wires and formed.
Three steel wire of internal layer of described heart yearn, nine process wires and 15 cover wires are compiled the sth. made by twisting twisted with the fingers to identical, the wire pitch 5.0 ~ 16.0mm of heart yearn, and each steel wire diameter is 0.175mm in the heart yearn.The sth. made by twisting of three steel wires of the internal layer of described steel strand, 15 steel wires of middle nine steel wires and skin is the some contact to identical between each steel wire of described steel strand, steel strand wire pitch 5.0 ~ 16.0mm, and each steel wire diameter is 0.175mm in the steel strand.
The lay pitch of described outer winding steel wire is 5.0mm, and outer winding steel wire diameter is 0.15mm.
The utlity model has following beneficial effect: adopt as after the above-mentioned technical scheme, the steel cord adds a winding steel wire volume by the heart yearn six roots of sensation steel strand outer with being wrapped in heart yearn and twists with the fingers moulding, formed by 190 steel wires altogether, and the intensity height, bearing capacity is big.Be the some contact between the steel wire thigh, so transportable space is big and flexible strong between each layer monofilament, fatigue performance is good.Heart yearn and steel strand and cord body are ordinary lay, and strike-through between the steel strand, rubber can fully be penetrated in the steel cord, decay resistance, and security is good, has prolonged the service life of tire.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In Fig. 1, the utility model provides a kind of engineering tire steel cord, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, be ordinary lay between cord body and the outer winding steel wire, described cord body is compiled to twist with the fingers by heart yearn 1 six roots of sensation steel strand 2 outer with being wrapped in heart yearn and is formed, described heart yearn 1 is by three steel wire of internal layer, nine process wires and 15 cover wires are compiled in the same way to twist with the fingers and are formed, three steel wire of internal layer of described heart yearn 1, nine process wires are compiled the sth. made by twisting of sth. made by twisting to identical with 15 cover wires, wire pitch 5.0 ~ the 16.0mm of heart yearn 1, each steel wire diameter is 0.175mm in the heart yearn 1, described every steel strand 2 is by three steel wire of internal layer, nine process wires and 15 cover wires are compiled in the same way to twist with the fingers and are formed, three steel wires of the internal layer of steel strand 2, the sth. made by twisting of 15 steel wires of middle nine steel wires and skin is to identical, be the some contact between each steel wire of described steel strand 2, steel strand 2 wire pitches 5.0 ~ 16.0mm, each steel wire diameter is 0.175m in the steel strand 2, the lay pitch of described outer winding steel wire is 5.0mm, and outer winding steel wire diameter is 0.15mm.
