Abstract
The utility model discloses a nineteen fold steel cord used in pneumatic tire, which is twisted by a plurality of steel strands. The steel wire has a circular cross section which is concurrently twisted by nineteen steel wires at a time to form a regular hexagon cross section, and the contact surface between the steel wires is line contact. The utility model has compact structure, and the core has high intensity, small diameter and low manufacturing cost, which is fitting for the requirement of light weight of tire.
Description
Technical field
The utility model relates to a kind of steel cord of using as band bundled layer in the pneumatic tire.
Background technology
In the prior art, mainly adopt opening structure with the steel cord, have the slit between the steel wire, be convenient to the infiltration of rubber as band bundled layer in the pneumatic tire.Be the intensity of raising steel cord, the steel cord of opening structure, gauge of wire is thicker, is difficult to satisfy the tire lightweight requirements.
Summary of the invention
The utility model provides a kind of intensity that can keep the steel cord, the diameter of cord is less simultaneously, can reduce the consumption of required steel cord, thereby can reduce the weight of tire, meet the tire lightweight requirements, and the tire that can reduce production costs is with 19 strands of steel cords.
The utility model adopts following technical scheme: a kind of 19 strands of steel cords, and to compile sth. made by twisting by steel wire and form, the cross section of steel wire is circular, it is done to compile in the same way by 19 steel wires and twists with the fingers once one-tenth rope, forms regular hexagonal section, is the line contact between the steel wire.
The lay pitch of described a kind of 19 strands of steel cords is 10mm, twist with the fingers to be Z to.
A kind of 19 strands of steel cords of the utility model are owing to be that line contact, contact area are big between the steel wire of steel cord.It has structure closely, and cord diameter can reduce, and can reduce the density and the glue consumption of cord, reduce tire drag, and can keep identical humidification simultaneously, can alleviate the weight of steel cord in the tire, reduce the tire production cost, meet the tire lightweight requirements.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of 19 strands of steel cords of the utility model.
The specific embodiment
According to shown in Figure 1, a kind of steel cord of the utility model, compile sth. made by twisting by steel wire and form, the cross section of steel wire is circular, and it is to be done once to compile to twist with the fingers in the same way to form by 19 steel wires, the diameter of heart yearn is 0.20mm, all the other steel wire diameter are 0.175mm, form regular hexagonal section, the sth. made by twisting of steel cord to be Z to, the lay pitch is 10mm, and the line that forms standard between steel wire and the steel wire contacts.
Claims (3)
1, a kind of 19 strands of steel cords are formed by steel wire volume sth. made by twisting, and the cross section of steel wire is circular, and the volume sth. made by twisting forms to it is characterized in that it doing in the same way by 19 steel wires, and the formation regular hexagonal section is the line contact between the steel wire.
2, a kind of 19 strands of steel cords according to claim 1, the lay pitch that it is characterized in that it is 10mm.
3, a kind of 19 strands of steel cords according to claim 1, the sth. made by twisting that it is characterized in that it to for Z to.
