Abstract
The utility model discloses a fifteen fold steel cord used in pneumatic tire, which is twisted by a plurality of steel strands, wherein the steel strand is twisted by a plurality of steel wire which is helically buckled. The steel strand twisted by five steel wires has a pentagon cross section and the steel strand twisted by three steel wires has a triangle cross section. The steel strand and the steel cord have the same direction of twist and the lay length is 20mm and 8.5mm respectively. The steel cord of the utility model has high resistances to corrosion and impact.
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
General steel cord is because the lay pitch is bigger, and the slit between the steel wire is little, and percentage elongation is little, when it during as tire belt, corrosion resistance is poor, shock resistance is not strong, influences the service life of tire.
The tire belt that the utility model provides that a kind of corrosion resistance is strong, shock resistance is strong, puncture, percentage elongation are good is with 15 strands of steel cords.
The utility model adopts following technical scheme: a kind of 15 strands of steel cords, compiling sth. made by twisting by steel strand forms, steel strand is compiled to twist with the fingers by steel wire and is formed, the cross section of steel wire is circular, its key is that described steel wire is crooked in the shape of a spiral, described steel cord is to be compiled by three strands of steel strands that to twist with the fingers into the cross section be triangular shaped steel cord, and per share steel strand is to be compiled by five steel wires that to twist with the fingers the cross section that forms be pentagonal steel strand.
The lay pitch of described steel cord is 8.5mm, and the lay pitch of steel strand is 20mm.
The sth. made by twisting of described steel strand and steel cord is to identical, be S to.
Adopt technique scheme, the steel wire of steel cord is handled through predeformation, steel wire is crooked in the shape of a spiral, even under high lay pitch production status, still have bigger slit between the steel wire, make that the Breaking elongation of steel cord is very high and strike-through is abundant, especially the steel cord still has very high Breaking elongation after covering glue, can absorb impact, improve the anti-corrosion property energy of cord simultaneously.The band bundled layer that the steel cord of this structure is used for radial; protective layer as tire; can improve the capacity of resisting impact load of tire; prevent that carcass is impaired; can prevent again that simultaneously band bundled layer steel cord from causing the infiltration of moisture to cause steel cord corrosion and damage because of puncture and scarfing, greatly improves the security and the service life of tire.
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 15 strands of steel cords of the utility model.
According to Fig. 1, the utility model is compiled to twist with the fingers by 15 steel wires and is formed, gauge of wire is 0.38mm, earlier steel wire is handled through special predeformation, made steel wire in the shape of a spiral after the bending, 5 steel wires are compiled to twist with the fingers into the cross section be pentagonal steel strand, three strands of steel strands being compiled again and being twisted with the fingers into the cross section is leg-of-mutton steel cord, the sth. made by twisting of steel strand and steel cord to be S to, the lay pitch of steel strand is 20mm, the lay pitch of steel cord is 8.5mm.
Claims (3)
1, a kind of 15 strands of steel cords, compiling sth. made by twisting by steel strand forms, steel strand is compiled to twist with the fingers by steel wire and is formed, the cross section of steel wire is circular, it is characterized in that described steel wire is crooked in the shape of a spiral, described steel cord is to be compiled by three strands of steel strands that to twist with the fingers into the cross section be triangular shaped steel cord, and per share steel strand is to be compiled by five steel wires that to twist with the fingers the cross section that forms be pentagonal steel strand.
2, a kind of 15 strands of steel cords according to claim 1, the lay pitch that it is characterized in that described steel cord is 8.5mm, the lay pitch of steel strand is 20mm.
