Abstract

PURPOSE: A carcass structure of a bias tire is provided to improve durability and the productivity in the process of molding a tire by making the plural carcass edges not positioned at the rim flange. CONSTITUTION: Plural carcasses(1,2,3,4) are turned up to the bead core(5). The carcasses(2,3) of the same width are arranged on the top of the carcass(1) having the longest width crisscross. The carcass(4) having the shortest width is arranged on the top of the carcass(3) and on the carcass(4) the bead core is installed. Each carcass is turned up to cover the bead core. Durability is improved and productivity of the molding process of a tire is improved because the plural carcass edges are not positioned at the rim flange having severe movement.

Description

바이어스 타이어의 카카스 구조 { Carcass member of bias tire}Carcass member of bias tire

본 발명은 바이어스 타이어의 카카스구조에 관한 것으로서, 더욱 상세하게는 비드에 턴업되는 다수의 카카스 에지부가 림프랜지부위에 위치되지 않게 하여 내구성을 향상시킬 수 있게 하는 동시에 타이어 성형공정의 생산성을 향상시킬 수 있게 하는 바이어스 타이어의 카카스 구조에 관한 것이다.The present invention relates to a carcass structure of a bias tire, and more particularly, a plurality of carcass edge portions turned up in a bead are not located at a lymphangein portion, thereby improving durability and improving productivity of a tire forming process. To a carcass structure of a bias tire.

일반적으로 바이어스 타이어는 첨부된 도면 도 1 에 도시되는 바와 같이, 다수(4개에서 8개 정도 도면에는 4개만 도시됨)의 카카스(1)(2)(3)(4)를 비드코아(5)에 턴업(turn-up)시켜 구성되며 적층되는 각 카카스(1)(2)(3)(4)의 경사진 코드는 서로 엇갈리도록 적층시켜 구성되는 것이다.In general, the bias tire is a plurality of carcass (1) (2) (3) (4) (as shown in FIG. 5) The inclined cords of each carcass (1) (2) (3) (4) which are configured by being turned up and turned up are stacked so as to cross each other.

비드코아(5)에 턴업되는 각 카카스(1)(2)(3)(4)는 그 단부가 있기 마련이고, 이와 같은 카카스의 단부에는 응력이 집중될 수밖에 없어 되도록이면 움직임이 적어야 크랙과 세파레이션을 방지할 수 있다.Each carcass (1) (2) (3) (4) that is turned up in the bead core (5) has an end portion, and the end of such carcass must be concentrated in such a way that stress must be concentrated so that the movement is small. Oversegmentation can be prevented.

첨부된 도면 도 2 는 종래의 카카스 턴업 방식을 도시한 단면도로써, 비드코아(5)의 저면에 같은 폭을 가지는 1,2번 카카스(1)(2)를 배치하고, 비드코아의 상부에 상기 1,2번 카카스(1)(2) 폭과 다른 폭을 가지는 3,4번 카카스(3)(4)를 배치시킨 다음 3,4번 카카스(3)(4)는 턴다운(turn-down)시키고, 1,2번 카카스(1)(2)는 비드코아(5)에 턴업(turn-up)시켜 타이어를 성형시켜 왔다.2 is a cross-sectional view illustrating a conventional carcass turn-up method, and the first and second carcasses 1 and 2 having the same width are disposed on the bottom surface of the bead core 5, and the upper part of the bead core is disposed. 3, 4 carcass (3) (4) having a width different from the 1, 2, 1 carcass (1) (2) in the width is placed, then 3, 4 carcass (3) (4) is turned The car was turned down and the carcass numbers 1 and 2 were turned up on the bead core 5 to form a tire.

그러나 이와 같은 종래의 카카스 턴업방법은 타이어의 성형시 턴다운과 턴업즉, 두 번의 공정을 거쳐야 함으로 생산성이 낮은 문제점이 있는 것이다.However, such a conventional carcass turn-up method has a problem of low productivity because it requires two steps of turn-down and turn-up when forming a tire.

첨부된 도면 도 3 은 종래의 다른 카카스 턴업 방식을 도시한 단면도로써, 1,2,3,4번 카카스(1)(2)(3)(4)의 폭을 모두 다르게 제단시키고 이들 카카스를 비드코아(5)의 하부에 배치시킨 후 각 단부를 턴업시켜 타이어를 성형시키는 것이다.3 is a cross-sectional view showing another conventional carcass turn-up method, and the carcasses 1, 2, 3, and 4 of the carcasses 1, 2, 3, and 4 are differently embossed. After the casing is placed under the bead core 5, each end is turned up to form a tire.

이는 한번의 턴업공정으로 타이어를 성형시킴에 따라 생산성은 증대될 수 있으나 각각의 카카스(1)(2)(3)(4) 폭을 다르게 재단시켜야 되어 전체적인 생산성이 저하되는 문제점이 있는 것이다.This is because the productivity can be increased by molding the tire in one turn-up process, but each carcass (1) (2) (3) (4) width to be cut differently, there is a problem that the overall productivity is lowered.

첨부된 도면 도 4 은 종래의 또 다른 카카스 턴업 방식을 도시한 단면도로써, 동일한 폭을 가지는 각각의 카카스(1)(2)(3)(4)를 순차적으로 어긋나게 배치한후 각 단부를 턴업하여 타이어를 성형시키는 것이다.4 is a cross-sectional view showing another conventional carcass turn-up method, and each carcass (1) (2) (3) and (4) having the same width are sequentially disposed to shift each end. It turns and molds a tire.

이와 같은 턴업방법은 각각의 카카스폭이 동일함에 따라 재단공정이 단순해지고, 한번의 턴업공정만을 시행함에 따라 생산성이 매우 높은 장점은 있으나 완성된 타이어를 림에 장착시킬 때 1번 카카스(1)의 단부가 림플랜지(6)가 위치하는 지역에 위치됨으로써, 단부에 집중적으로 응력이 발생되어 크랙과 세파레이션을 유발시키는 문제점이 있는 것이다.This turn-up method has the advantage that the cutting process is simplified as each carcass width is the same, and the productivity is very high as only one turn-up process is performed, but when the finished tire is mounted on the rim, the number 1 carcass (1 By the end of the) is located in the region where the rim flange 6 is located, there is a problem that the stress is concentrated in the end causing cracks and separation.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 비드에 턴업되는 다수의 카카스 에지부가 림플랜지부위에 위치되지 않게 하여 내구성을 향상시킬 수 있게 하는 동시에 타이어 성형공정의 생산성을 향상시킬 수 있게 하는바이어스 타이어의 카카스 구조를 제공함에 그 목적이 있다.The present invention has been made to solve the above-described problems, the present invention is to improve the productivity of the tire forming process while at the same time to improve the durability by preventing a number of carcass edge portion turned up in the bead rim flange portion It is an object of the present invention to provide a carcass structure of a bias tire.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 즉, 본 발명은 다수의 카카스가 비드에 턴업설치되는 바이어타이어에 있어서, 최장폭을 가지는 1번 카카스의 상면에 같은 폭을 가지는 2,3번 카카스를 어긋나게 배치시키고, 3번 카카스의 상면에 최단폭을 가지는 4번 카카스를 배치시키며, 이의 상부에 비드코아를 설치시키고, 각 카카스의 단부를 턴업시켜 비드코아를 감싸도록 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, according to the present invention, in the tires in which a plurality of carcasses are turned up on the bead, the second and third carcasses having the same width are alternately disposed on the upper surface of the first carcass having the longest width, and the third carcass 4 is placed on the top of the carcass having the shortest width, the bead core is installed on the upper portion, and the end of each carcass is characterized in that it is configured to surround the bead core.
