Description
Technical field
The utility model relates to steel cord technical field, in particular to a kind of tire belt steel cords.
Background technique
Belt is the main stressed member of radial, periodically bears the deformations such as stretching, bending, shearing and answers
Power.Belt plays an important role to the safety of tire, comfort, high speed performance and endurance quality, although these performances with
Belt severing angle, width and steel cord arranging density are related, but the closest with the property relationship of steel cord.Banding
Layer steel cord only has intensity with higher, higher strike-through, fatigue performance, can just help to improve the property of belt
Can, and then improve tire quality.
Under competitive pressure, cost efficiency is also the requisite measure of tire enterprise seeking development in the market, limited resources
Saving use brought into schedule by manufacturing industry.Therefore, as the steel cord of tyre framework material constantly receive performance, cost with
The challenge of energy conservation, therefore a kind of strike-through performance that can improve steel cord is provided, it prevents core strand from migrating, improves the carrying of tire
Ability and security performance reduce steel cord relative usage, reduce the tire belt steel cord of Tire production cost.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, provides a kind of tire belt steel curtain
Line.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of tire belt steel cord,
Including steel cord ontology, the steel cord ontology is twisted by core wire steel wire and outsourcing steel wire volume, and the outsourcing steel wire is equal
The even outside for being distributed in core wire steel wire；
The quantity of the core wire steel wire is two, and the core wire gauge of wire is 0.34~0.36mm；
The quantity of the outsourcing steel wire is 8, and the outsourcing gauge of wire is 0.32~0.34mm, and described is outer
Gap between Baogang's silk is two neighboring is 50 μm~100 μm；
The section of the steel cord ontology is ellipse, the ratio of the short diameter 1 of the cord ontology and long diameter d2
Value is 0.83 ± 0.10.
As an improvement, the core wire gauge of wire is 0.35mm, the outsourcing gauge of wire is 0.33mm.
As an improvement, the lay pitch of the core wire steel wire is 10mm, the lay pitch of the outsourcing steel wire is 18mm.
As an improvement, it is that S is twisted that the core wire steel wire and outsourcing steel wire, which obtains orientation,.
As an improvement, the core wire steel wire is identical with the orientation of outsourcing steel wire.
The utility model compared with prior art the advantages of be: by increase core wire gauge of wire, reduce steel wire number
Amount, structure is more simple, and the more traditional steel cord in the gap between outsourcing steel wire increases 59.7%, it is ensured that when tyre vulcanization forms
Flowing of the rubber in steel cord core wire is unimpeded, enhancing rubber to the anchorage effect of core wire, prevent tire in use because
Tyre failure caused by the migration of steel cord core strand, improves shock resistance, the corrosion resistance of tire, and that improves tire uses the longevity
Life reduces steel cord production cost and Tire production cost.
Detailed description of the invention

It is as shown in the figure: 0, steel cord ontology 1, core wire steel wire；2, outsourcing steel wire.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with Fig. 1, a kind of tire belt steel cord, including steel cord ontology 0, the steel cord ontology 0 is by core
Line steel wire 1 and the volume of outsourcing steel wire 2 are twisted, and the outsourcing steel wire 2 is evenly distributed in the outside of core wire steel wire 1；Described
The quantity of core wire steel wire 1 is two, and the diameter of the core wire steel wire 1 is 0.34~0.36mm；The number of the outsourcing steel wire 2
Amount is 8, and the diameter of the outsourcing steel wire 2 is 0.32~0.34mm, the gap between the outsourcing steel wire 2 is two neighboring
It is 50 μm~100 μm；The section of the steel cord ontology 0 is ellipse, and the short diameter 1 and length of the cord ontology 0 are straight
The ratio of diameter d2 is 0.83 ± 0.10, and the diameter of the core wire steel wire 1 is 0.35mm, and the diameter of the outsourcing steel wire 2 is
0.33mm, the lay pitch of the core wire steel wire 1 are 10mm, and the lay pitch of the outsourcing steel wire 1 is 18mm, the core wire steel wire
