Abstract
The utility model discloses a four strand steel wire which is used in a pneumatic tire. The utility model is made of steel wires through weaving and twisting, and the cross section of the steel wire is circular. The utility model is made through the process that four steel wires make one time weaving and twisting in the same direction to form a chain-shaped cross section, wherein the contact surface between the steel wires is a line contact. The utility model has better strength and corrosion resisting properties, and meanwhile, the diameter of the steel wire is smaller, so the utility model can satisfy the requirement of light weight of a 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 and decay resistance, anti-fatigue performance, cord diameter is less simultaneously, satisfies the tire lightweight requirements, and the tire that can reduce production costs is with four strands of steel cords.
The utility model adopts following technical scheme: a kind of four 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 once to compile to twist with the fingers in the same way to form by 4 steel wires, formation chain cross section, the contact-making surface between the steel wire is the line contact.
The lay pitch of described a kind of four strands of steel cords is 18mm, twist with the fingers to be S to.
A kind of four strands of steel cords of the utility model, because the contact-making surface between the steel wire of steel cord is that line contact, contact area are big, cord diameter can reduce, under the identical humidification of maintenance, can alleviate the weight of steel cord in the tire, reduce the tire production cost, meet the tire lightweight requirements.The cross section of steel cord is a chain structure simultaneously, there is certain slit between the steel wire, be convenient to rubber osmosis, prevent that band bundled layer steel cord from causing moisture infiltration to cause the cord corrosion and damage because of puncture and scarfing, has decay resistance, anti-fatigue performance and wear resistance preferably.It is an one-step shaping, and therefore the production cost of this steel cord can reduce greatly.
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 four strands of steel cords of the utility model.
The specific embodiment
According to shown in Figure 1, a kind of four strands of steel cords of the utility model, compiling sth. made by twisting by steel wire forms, the cross section of steel wire is circular, and it is to be done to compile in the same way to twist with the fingers to form by 4 steel wires, and steel wire diameter is 0.35mm, form the chain tee section, the sth. made by twisting of steel cord to be S to, the lay pitch is 18mm, steel wire and contact-making surface between the steel wire are that the line of standard contacts.
Claims (3)
1, a kind of four strands of steel cords compile to be twisted with the fingers by steel wire and to be formed, and the cross section of steel wire be circular, it is characterized in that it is done once to compile to twist with the fingers in the same way to form by 4 steel wires, form the chain tee section, and the contact-making surface between the steel wire is that line contacts.
2, a kind of four strands of steel cords according to claim 1, the lay pitch that it is characterized in that it is 18mm.
3, a kind of four strands of steel cords according to claim 1 is characterized in that: its sth. made by twisting to for S to.
