Description

비드의 내구력을 증가시킨 공기입 타이어Pneumatic tires increase bead durability

본 고안은 비드의 내구력을 증가시킨 공기입 타이어에 관한 것으로서, 특히 동일면적(A)과 동일높이(h)의 조건하에서 단면계수(Z)가 가장 크게 되는 I형의 비임(beam) 형태로 비드코아를 배열하여 비드로 제조하고 상기 비드로 공기입 타이어를 구성함으로써, 공기입 타이어의 내구력 및 제성능이 향상되고 타이어 제조원가 절감 및 중량감소가 이루어지게 되는 비드의 내구력 및 제성능이 향상되고 타이어 제조원가 절감 및 중량감소가 이루어지게 되는, 비드의 내구력을 증가시킨 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire which increases the durability of the bead, in particular bead in the form of a beam (I) in the form of a beam (I) having the largest cross-sectional coefficient (Z) under the conditions of the same area (A) and the same height (h) By arranging cores to make beads and constructing pneumatic tires from the beads, the durability and manufacturing performance of the pneumatic tires are improved, tire manufacturing cost reduction and weight reduction are improved, and tire manufacturing cost is improved and tire manufacturing cost is improved. It relates to a pneumatic tire that increases the durability of the bead, which is to be reduced and reduced weight.

일반적으로 공기입 타이어는 자동차에 취부되는 그 순간부터 작게는 자동차의 무게에서부터 크게는 자동차 무게의 수 배에 해당하는 하중을 견디어야만 하며, 이런 하중들이 타이어에 작용될 때 대부분의 하중을 비드가 받게 된다.In general, pneumatic tires must withstand the load from the moment they are mounted on the car, from the weight of the car to the weight of the car, up to several times the weight of the car. do.

이때, 상기 비드에 작용되는 외부 하중을 분석해 보면 특별한 경우를 제외하고는 대부분의 경우에 상기 타이어 비드에 작용되는 외력은 벤딩 모우먼트이다.At this time, when analyzing the external load applied to the bead in most cases, the external force applied to the tire bead except the special case is the bending moment.

그러나, 종래에는 제2도에서도 참조되는 것처럼 비드(2')의 코아(3) 배열 형상이 사각형 배열인 까닭으로 외부로부터 주어지는 벤딩 모우먼트에 대한 저항성이 좋지 못하여 공기입 타이어의 주행성능 및 내구력을 하락시키는 문제점이 있었으며, 아울러 타이어 제조원가의 상승 및 중량증가의 원인으로 적용되는 단점이 있었다.However, in the related art, since the core 3 arrangement of the beads 2 'is a rectangular arrangement as described with reference to FIG. 2, resistance to bending moments given from the outside is not good, thereby improving driving performance and durability of the pneumatic tire. There was a problem of falling, and also a disadvantage of being applied as a cause of an increase in the tire manufacturing cost and weight increase.

본 고안은 이러한 종래의 문제점을 개선코자 안출된 것으로서, 다수개의 비드코아가 I 비임의 단면 형태이고, I 비임의 단면 형태 중 웹(web)부분이 타이어의 반경방향으로 배열한 구조적 특징이 있으며, 이하 첨부도면을 참조하여 본 고안에 따른 비드의 내구력을 증가시킨 공기입 타이어의 구성을 상세히 설명하면 다음과 같다.The present invention has been made to improve such a conventional problem, a plurality of bead core is a cross-sectional shape of the I beam, the web portion of the cross-sectional shape of the I beam has a structural feature arranged in the radial direction of the tire, Hereinafter, the configuration of the pneumatic tire which increased the durability of the bead according to the present invention with reference to the accompanying drawings in detail as follows.

제1도는 본 고안에 따른 공기입 타이어의 부분 단면도,1 is a partial cross-sectional view of a pneumatic tire according to the present invention,

제2도는 종래 공기입 타이어의 부분 단면도,2 is a partial cross-sectional view of a conventional pneumatic tire,

본 고안에 따른 비드의 내구력을 증가시킨 공기입 타이어는 제1도에서 참조되는 바와 같이, 다수개의 비드코아(3)를 갖는 공기입 타이어에 있어서, 상기 비드코아(3)를 I 자 형태로 배열한 비드(2)를 사용하여 공기입 타이어를 구성한다.The pneumatic tire which increased the durability of the bead according to the present invention is a pneumatic tire having a plurality of bead cores (3), as shown in Figure 1, the bead cores (3) arranged in the I-shape One bead 2 is used to construct a pneumatic tire.

이상과 같이 구성되는 본 고안에 따른 공기입 타이어의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the pneumatic tire according to the present invention configured as described above are as follows.

본 고안에서는 비드코아(3)가 I 자형으로 배열된 비드(2)를 사용하는데, 구조역학적인 측면에서 볼 때 I 형 단면은 사각형 단면에 비해 단면계수(Z)가 2배 이상 크므로 내(耐) 벤딩 모우먼트 성능면에서 우수하고, 동일하중에 대해 적은 수의 비드코아(3)로도 충분한 성능을 얻을 수 있어 중량감소의 효과가 있으며, 이로 인해 타이어의 제조원가를 절감케 되면서도 공기입 타이어의 제조시 발생되는 에어입(air 入) 형상과 내구력의 하락을 방지하게 되는 잇점이 있게 된다.In the present invention, the bead core 3 is a bead (2) arranged in an I-shape, in terms of structural dynamics, the I-shaped cross section is more than twice as large as the cross-sectional coefficient (Z) compared to the rectangular cross section.耐) Excellent in terms of bending moment performance, and sufficient performance can be obtained even with a small number of bead cores (3) for the same load, thereby reducing the weight of the tire and reducing the manufacturing cost of the tire. There is an advantage of preventing a decrease in air inlet shape and durability generated during manufacturing.
