Abstract

본 발명은 타이어의 단면형상을 개선하여 타이의 주행에 의하여 발생되는 벨트부 및 비드부에서의 전단변형의 편차를 최소화사켜 세파레이션의 발생을 방지하여 타이어의 내구성을 향상시킬 수 있도록 하는 공기입 레디얼 타이어를 제공하기 위한 것이다.The present invention relates to an air-intake radial type tire which improves a cross-sectional shape of a tire and minimizes a deviation of shear deformation at a belt portion and a bead portion caused by traveling of a tie, Tire.

종래에 있어서의 타이어 단면형상의 경우, 초기(타이어설계시)의 단면형상이 타이어의 내부로 공기압이 작용할때의 단면형상과 거의 유사하여 공기압 작용시의 전단변형량이 작게되어 결과적으로 전단변형량의 편차가 커기게 되므로 카카스에 걸리는 장력의 균일화를통한 벨트에지부에서의 응력완화 및 비드부 카카스 턴업 단말부에서의 응력완화의 효과가 저감되어 세파레이션이 발생되는 결과를 초래하게 되는 단점이 있었던바, 본 발명은 카카스(5)와 트래드(1) 사이에 최소한 2층 이상의 벨트층(2)을 갖는 레디얼 타이어에 있어서, 단면 최대폭을 형성하는 사이드웰(4)부분이 레디얼방향으로 평행한 직선(STRAIGHT LINE)으로 구성되며 그 직선의 길이는 단면높이의 10~20%의 비율로 형성시켜 공기압만이 작용할때와 공기압과 하중이 동시에 작용할 때의 전단변형의 편차를 작게 함으로써, 세파레이션의 발생을 억제하여 내구성을 향상시킬 수 있는 것임.In the case of the conventional cross-sectional shape of the tire, the cross-sectional shape at the initial stage (when designing the tire) is substantially similar to the cross-sectional shape when air pressure acts on the inside of the tire, The effect of the stress relaxation at the belt edge portion and the stress relaxation at the terminal portion of the bead carcass turn-up terminal through the equalization of the tension applied to the carcass is reduced, resulting in a disadvantage that the delamination is generated The present invention relates to a radial tire having at least two belt layers (2) between a carcass (5) and a tread (1), characterized in that a part of the side well (4) STRAIGHT LINE. The length of the straight line is 10 ~ 20% of the height of the cross section. It is formed when ratio of air pressure and load acts simultaneously. By reducing the deviation of the deformation, it is possible to suppress the generation of the separation and improve the durability.
