Description

비드부를 개량한 자동차용 타이어{Vehicle tire improved bead member}[0001] The present invention relates to a vehicle tire improved bead member,

본 발명은 자동차용 타이어에 관한 것으로, 특히 비드부를 개량하여서 된 타이어에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automobile tires, and more particularly to tires obtained by improving bead portions.

타이어는 트레드와 트레드 양측의 사이드월과 사이드월 하단의 비드부로 구성되고, 비드부는, 다수의 비드와이어를 합체하여 단면이 육각형 또는 사각형으로 형성되는 비드코어와, 비드코어 상측의 비드필러와, 비드코어와 비드필러를 감싸는 카카스와, 카카스 외측의 채퍼(Chafer)로 구성되어 있다.The tire consists of a tread, sidewalls on both sides of the tread, and a bead portion at the bottom of the sidewall, and the bead portion comprises a bead core in which a plurality of bead wires are combined to form a hexagon or a quadrangle, a bead filler above the bead core, and a bead. It consists of a carcass surrounding a core and a bead filler, and a chaper outside the carcass.

그런데 이와 같은 타이어의 비드부는 카카스의 장력에 의하여 비틀리면서 비드코어의 형상이 일그러진다던지, 육각형이나 사각형으로 되는 비드코어의 모서리에 의하여 카카스가 손상된다던지 하는 결점이 있다. However, the bead portion of such a tire twists due to the tension of the carcass, and the shape of the bead core is distorted, or the carcass is damaged by the corner of the bead core that is hexagonal or quadrangle.

비드코어의 형상이 온전하게 유지되어야 카카스의 움직임이 적어지고 차량의 휠과 안착이 잘 되어 비드부의 발열량이 적어지게된다. 그러나 비드코어의 형상이 일그러지게되면 카카스의 움직임이 많아지게 되며 그리하여 발열량이 많아져 비드부의 내구성을 감소시키게 된다. 그리하여, 상기 비드코어가 비드코어를 외부에서 감싸는 커버를 포함하여서 되는 타이어가 특허 공개 제1020040048211호로 제공된 바 있다. 그런데, 이와 같은 선행 기술의 타이어에 있어서는 비드코어를 구성하는 비드와이어들이 흐트러지는 일은 방지한다 하더라도, 비드코어에 의하여 카카스가 손상되는 것을 방지할 수는 없었다.
When the shape of the bead core is maintained intact, the movement of the carcass is reduced and the seat of the vehicle is well seated, so that the heat generation amount of the bead portion is reduced. However, when the shape of the bead core is distorted, the movement of the carcass increases, thereby increasing the amount of heat generated, thereby reducing the durability of the bead part. Thus, a tire in which the bead core includes a cover that surrounds the bead core from the outside has been provided in Patent Publication No. 1020040048211. However, in such a prior art tire, even if the bead wires constituting the bead core are prevented from being disturbed, the carcass cannot be prevented from being damaged by the bead core.

이에 본 발명은, 비드와이어들이 소기의 형상으로 적층되어 형성되는 비드코어가, 카카스의 장력에 의하여 비틀어지고 흐트러지는 일이 없게 하여 카카스 운동량을 감소시키면서도, 당겨지는 카카스의 장력으로 비드코어에 의하여 카카스가 손상되는 일을 방지할 수 있는 비드부 구조를 가지는 타이어를 제공하여야 한다는 과제를 해결하고자 한다.
Accordingly, the present invention, the bead core is formed by stacking the bead wires in the desired shape, the bead core is pulled by the tension of the carcass pulled while reducing the carcass momentum so as not to be twisted and distracted by the tension of the carcass It is intended to solve the problem of providing a tire having a bead structure that can prevent the carcass from being damaged.

위와 같은 과제를 해결하기 위하여 본 발명은 비드코어와 카카스 사이에 하나 이상의 격판을 설치하여서 되는 타이어를 제공하며, 상기 격판은 그 단부에서 층을 이루어 격판들이 그 단부에서 카카스에 가하는 응력을 분산하며, 나아가 상기 격판이 내측에 비드코어를 이루는 비드와이어의 직경보다 0.1~05mm 큰 직경을 가지는 홈을 가져서 되는 격판을 포함하는 것을 특징으로 하는 타이어를 제공한다.
In order to solve the above problems, the present invention provides a tire formed by installing at least one diaphragm between the bead core and the carcass, the diaphragm layered at the end to distribute the stress applied to the carcass at the end of the diaphragm Further, there is provided a tire, characterized in that the diaphragm comprises a diaphragm having a groove having a diameter of 0.1 ~ 05mm larger than the diameter of the bead wire forming a bead core inside.

위와 같은 본 발명의 타이어는, 비드와이어들이 적층되어 단면 형상이 육각형이나 사각형을 이루는 비드코어가, 격판들에 의하여 카카스와 이격되게 함으로서, 비드코어가 카카스의 장력에 의하여 비틀어지고 흐트러지는 일이 없게 하며, 그리하여 카카스 운동량을 감소시키는 효과가 있으며, 당겨지는 카카스의 장력이 비드코어에 직접적으로 가해지는 것이 아니라 격판들을 거쳐서 가해지게 되어 비드코어의 모서리들이 카카스를 손상하는 일을 방지하게 되는 효과가 있다.
In the tire of the present invention as described above, the bead wires are stacked to form a hexagonal or square bead core cross-section of the carcass by the carcass, the bead core is twisted and distracted by the tension of the carcass It is effective in reducing the carcass momentum, and the tension of the carcass being pulled is applied through the diaphragms rather than directly on the bead core to prevent the edges of the bead core from damaging the carcass. It is effective.
