Abstract
The utility model provides a special-shaped tyre bead wire, which comprises a steel core wire and steel wires. A steel traveler is in a cable structure, and steel core wire is arranged in the center of the steel traveler. An outer layer of the steel traveler is formed by twining a plurality of strands of the steel wires in spiral mode, and the section of the whole steel traveler is in a circle shape. The special-shaped tyre bead wire has the advantages that the shape of the steel traveler is more stable so as to improve stability of tyre quality; the core wire and a layer line are not covered by glue, thereby being favorable for sliding of the steel wires when the steel wires are stressed and improving whole elasticity of the steel traveler; the strength of the section is high, thereby being capable of reducing designing width of the tyre bead portion, improving transitional uniformity of the stress on the tyre bead portion, and saving cost of the tyre simultaneously.
Description
Affiliated technical field
The utility model relates to a kind of tire, the bead coil that especially a kind of tire is used.
Background technology
The hexagonal wire circle is the most frequently used structure of present band tire, is covered glue and is entwined by single Φ 1.5-Φ 2.0mm Steel Wire Surface, has simple in structure, advantage of high production efficiency.But band tire for high inflation pressure or high distortion, whole steel wire radial tyre particularly, the hexagonal wire circle then has obvious defects, can cause the damage of the body cord of tire, and the body cord intensity that sustains damage sharply descends and causes tire blow-out.The body cord damage mainly is because the tire twisting resistance that bead coil bore under the situation of high inflation pressure or high distortion increases greatly, the wedge angle position mutual friction mutually of carcass steel cord and hexagonal wire circle, the carcass steel cord is that the steel wire monofilament twisting by Φ 0.15-Φ 0.25mm forms, the monofilament on top layer can at first rupture because of friction, and whole cord then blown out owing to strength degradation finally causes.This defective can cause the infantile failure of tire, causes a large amount of tires to pay compensation for, and brings hidden danger can for vehicle and driver's life security.
The utility model content
The purpose of this utility model is the defective that overcomes the hexagonal wire circle, and a kind of more practical band tire bead coil is provided, thereby guarantees the safety performance of band tire, and improves the tire cable shape bead coil in the life-span of tire
The purpose of this utility model is achieved through the following technical solutions: special-shaped steel bead wire, comprise wire cored wire and steel wire, and bead coil adopts cable shape structure, and the center is a wire cored wire; The outer winding by the steel wire strand helix formed, and whole bead coil cross section is rounded.
The technical solution of the utility model also comprises: steel wire is one or more layers.
In the multiple-structure, every layer of steel wire spiral is wound up as in the same way or oppositely.
The slightly larger in diameter of wire cored wire, steel wire diameter is smaller.
Wire cored wire and Steel Wire Surface are not covered glue.
Advantage of the present utility model has the more stable of bead coil shape, and (more than the 2.7MPa) can not be out of shape under the high pressure of tyre vulcanization, has improved the stability of tire quality; Heart yearn and layer line are not all covered glue, help the slip of steel wire when stressed, have increased the integral, flexible of bead coil, and tire folding dress is more prone to; Cable shape bead coil is arranged closely, and section intensity height can reduce tyre bead portion design width, improves the homogeneity of tyre bead portion transition of stress, also can save the tire cost simultaneously; Heart yearn and layer line steel wire all do not cover glue, have reduced the technological process that bead coil is produced, and have reduced equipment investment.
The tire size of using can be contained motor cycle tire, passenger car tire, picking-up vehicle tire, light truck and heavy duty truck tire, also can be used for field machine and off-the-road tyre, can also be used for aircraft tyre.The light tyre such as the 7.50R15 overall diameter 0.8m that are suitable for, off-the-road tyre 21.00R35 overall diameter then reaches 2m.

The specific embodiment
Special-shaped steel bead wire comprises wire cored wire 6 and steel wire 7, and bead coil 1 adopts cable shape structure, and the center is a wire cored wire 6; The outer winding by steel wire strand 7 helixs formed, and whole bead coil 1 cross section is rounded, has avoided the wedge angle position 3 mutually mutual friction of carcass steel cord with hexagonal wire circle 1.
Wire cored wire 6 is 1.2-Φ 8mm; Steel wire is Φ 0.96-Φ 2.2mm, and steel wire is one or more layers, and every layer of steel wire spiral is wound up as in the same way or oppositely, wire cored wire and Steel Wire Surface are not covered glue, and the overall diameter of bead coil is from about 3mm-41mm.
Claims (7)
