Stock migration, improves the bearing capacity and security performance of tire, reduces steel cord relative usage, reduces the steel curtain of Tire production cost
Line.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of tire belt steel cord is compiled core wire and 8 outsourcing steel wires made of twisting by 2 core wire steel wires and surrounded
The core wire volume is twisted, and Formation cross-section is the steel cord of ellipse, and the core wire steel wire diameter is 0.25~0.38mm, described
A diameter of 0.22~the 0.35mm of outsourcing steel wire, gap are more than 50 μm, the steel cord ellipse short diameter d1 and long diameter d2's
Ratio is 0.83 ± 0.10.
The core wire steel wire diameter is 0.35mm, a diameter of 0.33mm of outsourcing steel wire.
The core wire wire pitch is 6.3~12.5mm, and the outsourcing wire pitch is 12.5~20.0 mm.
The core wire wire pitch is 10mm, and the outsourcing wire pitch is 18mm.
The core wire steel wire and the outsourcing steel wire twist direction are identical.
The core wire steel wire and the outsourcing steel wire twist direction are twisted for S.
The steel cord adopts the steel wire suitable for NT, HT, ST, UT or MT intensity.
The advantageous effect that the utility model is reached：It is the HT steel of 3 × 0.20+6 × 0.35 that the utility model, which is as structure,
The improvement cord of cord, the HT of 2 × 0.35+8 of preferred embodiment × 0.33 steel cords and 3 traditional × 0.20+ in the utility model
6 × 0.35 HT with beam layer steel cord rigidity are suitable, but the impact absorbing energy of the utility model steel cord promotes 72%, and tire can be improved
Shock resistance；
The HT core strands steel wire diameters of 2 × 0.35+8 × 0.33 are thicker by 75% than the HT of 3 × 0.20+6 × 0.35；Cover wire gap
More than 50 μm, increases by 59.7% compared with the HT of 3 × 0.20+6 × 0.35, steel cord glue permeation performance can be improved, prevent core strand from migrating；
The HT of 2 × 0.35+8 × 0.33 steel cords are suitable with the HT filament strengths of 3 traditional × 0.20+6 × 0.35, but this is new
Steel cord Fracture Force/line density ratio promotes 7.5% compared with the HT of 3 × 0.20+6 × 0.35, in the identical item of cord intensity index
Under part, steel cord is less using weight, can mitigate tire weight；
The utility model steel cord ellipsoidal cross section can reduce cord calendering thickness, and then reduce rubber material using quantity, meet tire
Lightweight requirements；
The utility model is simple in structure, and composition steel wire diameter is thick, and the twist direction of two layers of steel wire is identical to be twisted type, it can be achieved that once compiling,
Production efficiency is high, can reduce steel cord production cost and Tire production cost.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is traditional with beams layer steel cord structural schematic diagram.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
As shown in Figure 1, the preferred embodiment structure of the utility model is the HT of 2 × 0.35+8 × 0.33, by 2 core wire steel
Silk 0 is compiled core wire and 8 outsourcing steel wires 1 made of twirl and is twisted around core wire volume, and Formation cross-section is the steel cord of ellipse, core
Line steel wire 0 and 1 twist direction of outsourcing steel wire are identical, are twisted for S, compile the when of twisting and can realize one-pass molding, simple in structure, production efficiency is high,
Wherein 0 a diameter of 0.35mm of core wire steel wire, 1 a diameter of 0.33mm of outsourcing steel wire, gap are more than 50 μm, the short diameter d1 of ellipse with
The ratio of long diameter d2 is 0.83 ± 0.10, and 0 lay pitch of core wire steel wire is 10mm, and 1 lay pitch of outsourcing steel wire is 18mm, the utility model
Each strength grade steel wire of NT, ST, UT, MT is applied also for, by increasing core wire gauge of wire, reduces steel wire quantity, structure is more
To be simple, the more traditional steel cord in gap between outsourcing steel wire increases 59.7%, it is ensured that rubber is in steel curtain when tyre vulcanization is molded
Flowing in core line is unimpeded, and enhancing rubber prevents tire in use because of steel cord core strand the anchorage effect of core wire
