본 발명은 타이어가 차량의 휠에 취부되어 있을 때 타이어의 내부 공기압 뿐만 아니라 차량자체, 승객 및 화물 등과 같은 외적 환경에 의하여 이 타이어의 비드와 휠 사이에서 비드가 변형되는 것을 측정하여 비드의 내구성이 향상된 타이어의 기초 데이터 제공으로 활용되는 타이어의 비드와 휠의 갭 측정장치에 관한 것이다.According to the present invention, when a tire is mounted on a wheel of a vehicle, the durability of the bead is improved by measuring the deformation of the bead between the tire and the wheel by the external environment such as the vehicle itself, passengers, and cargo as well as the internal air pressure of the tire. The present invention relates to a gap measuring device for a bead of a tire and a wheel used to provide basic data of an improved tire.

차량에 취부된 타이어의 경우, 이 타이어는 내부의 공기압 뿐만 아니라 차량, 승객, 화물 등에 의하여 많은 외적인 하중을 받게 되고, 또한 차량이 주행하는 경우 속도의 영향까지 받게 되는바, 이때 이와 같은 모든 내적 및 외적 하중을 타이어 전체에 전달하거나 또는 타이어를 차량의 휠에 고정시키는 역할을 하는 것은 타이어의 비드이다.In the case of a tire mounted on a vehicle, the tire is subjected to a large external load not only by the internal air pressure but also by the vehicle, passengers, cargo, etc., and also by the speed influence when the vehicle is driven. It is the bead of the tire that transmits the external load to the entire tire or secures the tire to the wheel of the vehicle.

통상 타이어를 설계할 때에는 비드부가 휠에 전체적으로 균일하게 접촉하여 이 비드부와 휠 사이의 접촉부분에 대한 하중의 분포가 균일하게 이루어지도록 설계되어 지나, 전술한 바와 같이 공기압, 하중, 차량의 주행속도에 의한 열변형 등에 의해 이 타이어의 비드부는 변형이 발생하게 되는데, 즉 도 3과 같이 타이어(3)의 비드부(5)는 이 비드부가 장착 고정된 휠(1)과 균일하게 접촉되지 않고 일부분이 도면과 같이 변형이 되어 하중의 분포가 어느 한 부분에 집중되는 현상이 발생하게 되므로, 이 비드부(5)의 수명을 단축시키게 된다.In general, when designing a tire, the bead part is uniformly in contact with the wheel as a whole, so that the load distribution on the contact portion between the bead part and the wheel is made uniform. As described above, the air pressure, the load, and the traveling speed of the vehicle are The bead part of the tire is deformed due to heat deformation due to, for example, the bead part 5 of the tire 3, as shown in FIG. As shown in this figure, the deformation occurs and the phenomenon in which the distribution of the load is concentrated in any one part occurs, which shortens the life of the bead part 5.

이러한 비드부(5)의 변형은 차량의 타이어 수명을 감소시키는 원인을 제공하게 되었다.This deformation of the bead portion 5 has provided a cause for reducing the tire life of the vehicle.
