본 고안은 타이어용 벨트구조에 관한 것으로, 특히 타이어의 내구성이 향상되도록 한 타이어용 벨트구조에 관한 것이다.The present invention relates to a belt structure for a tire, and more particularly to a belt structure for a tire to improve the durability of the tire.
종래 공기 래디얼타이어는 일반적으로 카카스층의 코드재료로 나이론, 폴리에스터등의 유기섬유를 이용하였으며, 벨트보강층으로서는 코드가 서로 교차한 2층의 강철벨트를 지니고 있어 내구성, 고속성, 조종안정성등이 바이어스타이어에 비해 향상되었다.Conventional air radial tires generally use organic fibers such as nylon and polyester as the cord material of the carcass layer, and the belt reinforcement layer has two layers of steel belts in which cords cross each other. This is improved compared to the bias tire.
그러나 종래 타이어용 벨트구조는 와이어 각각의 직경이 동일한 형태의 것을 사용하고 있었는 바, 타이어가 하중을 받아 주행중에 타이어 센터부와 숄더부에 반복적인 굴곡운동을 하게 되는 데, 그중 숄더부에는 많은 양의 스트래스를 받아 벨트의 엣지부분이 분리되는 현상이 발생되는 문제점이 있었다.However, in the conventional belt structure for tires, wires having the same diameter are used, and the tire is subjected to repeated load movements in the tire center portion and the shoulder portion while the tire is loaded. There was a problem that a phenomenon occurs that the edge portion of the belt is separated by the stress of.
스트레스를 받게 되는 이유를 제2도에 의거 좀더 상세히 설명하면, 자동차에 타이어를 취부시 림(11)에 타이어(12)가 하중을 받은 상태로 요철을 주행하게 되면 타이어(12)의 중앙부는 항상 지면에 닿게 되고, 숄더부(13)에 위치한 엣지부분(a~b)은 요철의 크기나 하중의 크기에 따라 지면에 닿았다·떨어졌다 하는 반복적인 운동을 하게 되므로 중앙부보다 스트레스가 많이 작용하게 된다.The reason for the stress is explained in more detail according to FIG. 2. When the tire is mounted on the vehicle, the tire 12 is always driven in the uneven state while the tire 12 is loaded under the rim 11. The edge parts (a to b) which are in contact with the ground and are located on the shoulder part 13 are subjected to repetitive movements of touching and dropping the ground according to the size of the unevenness or the size of the load. do.
이때 스트래스는 동일물질인 경우 보다는 타이어와 같이 강철와이어와 고무라는 서로 다른 이물질로 구성되거나, 이물질의 두께가 클 수록 많이 받게 되는 바, 타이어 사고의 대부분은 중앙부와 엣지부가 분리됨으로써 발생되는 것이다.In this case, the stress is composed of different foreign materials such as steel wire and rubber, such as tires, or the more the thickness of the foreign matter, the more the bar accident, most of the tire accident is caused by the separation of the center and the edge.
이런 문제점을 보완하기 위하여 나일론코드로 엣지커버 혹은 풀커버를 체용하고 있으나, 이 또한 타이어의 유니포 미터 저하 및 이상마모등이 문제점으로 제기되고 있다.In order to compensate for this problem, an edge cover or a full cover is used as a nylon cord, but this is also a problem caused by the reduction of tire uniformer and abnormal wear.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 카카스와 트래드부 사이에 권취된 벨트가 중심부에 갖춰진 와이어직경보다 엣지부에 갖춰진 와이어의 직경이 작게된 구조로, 주행중의 스트래스를 적게 받도록 하여 내구성을 향상시킨 타이어용 벨트구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and the structure of the wire wound at the edge of the belt wound between the carcass and the tread part is smaller than the diameter of the wire at the center, so that the stress of running is reduced. The purpose of the present invention is to provide a belt structure for a tire having improved durability.
상기와 같은 목적을 달성하기 위한 본 고안은, 와이어가 고무층의 내부에 들어 있는 벨트에 있어서, 상기 벨트의 중앙부에 있는 와이어의 직경보다 양쪽 측면부(엣지)에 있는 와이어의 직경이 작은 구조로 되어 있다.The present invention for achieving the above object has a structure in which the diameter of the wire at both side portions (edges) is smaller than the diameter of the wire at the center of the belt in the belt in which the wire is contained in the rubber layer. .
여기서 상기 와이어의 직경은, 상기 와이어의 직경보다 항상 크면서 직경이 0.5~2.0mm이고, 상기부의 폭은, 벨트전체의 폭에 대해 0.2~0.5배가 되도록 되어 있다.Here, the diameter of the wire is always larger than the diameter of the wire, and the diameter is 0.5 to 2.0 mm, and the width of the portion is 0.2 to 0.5 times the width of the entire belt.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 벨트의 단면도이고, 제2도는 본 고안을 설명하기 위한 타이어의 단면도로서, 본 고안은, 와이어가 고무층의 내부에 들어있는 벨트에 있어서, 타이어(12)의 단면상으로 볼때 벨트(1)의 중앙부(A)에 있는 와이어(2a)의 직경(D)보다 양쪽 측면부(엣지부;B)에 있는 와이어(2b)의 작은 구조로 되어 있다.1 is a cross-sectional view of the belt according to the present invention, Figure 2 is a cross-sectional view of the tire for explaining the present invention, the present invention, when viewed in the cross-sectional view of the tire 12 in the belt of the wire is contained inside the rubber layer The structure of the wire 2b in both side parts (edge part; B) is smaller than the diameter D of the wire 2a in the center part A of the belt 1.
여기서 상기 와이어(2a)의 직경(D)은 상기 와이어(2b)의 직경(d)보다 항상 크면서 0.5~2.0mm중 어느 것을 사용해도 좋다.Here, the diameter D of the wire 2a may be any one of 0.5 to 2.0 mm while always being larger than the diameter d of the wire 2b.
그리고 상기 엣지부(B)의 폭은, 벨트(1)전체의 폭(A+B)에 대해 0.2~0.5배가 되도록 한다.The edge portion B has a width of 0.2 to 0.5 times the width A + B of the entire belt 1.
상기와 같은 벨트(1)로 설형시킨 타이어를 2000cc급 전방엔진장착과 전륜구동인 자동차에 채용한 후 실내드럼내구성과 실차내구성을 시험한 결과 아래의 표1꽈 같은 결과를 얻을 수 있었다.The tires installed with the belt (1) as described above were employed in a vehicle equipped with a 2000cc front engine and all-wheel drive, and then tested for interior drum durability and actual vehicle durability. The results shown in Table 1 below were obtained.
[표1]Table 1
따라서 상기 벨트(1)의 양쪽 측면부(B)에 있는 와이어(2b)의 직경(d)이 중앙부(A)에 있는 와이어(2a)의 직경(Φ2)보다 작은 것으로 성형됨으로써, 타이어에 권취되었을 때 응력집중이 가장큰 타이어숄더부의 내구성이 보다 더 향상되도록 한 것이다. 이상 설명한 바와 같이 본 고안에 의하면, 주행중에 타이어의 숄더부가 스트래스를 적게 받도록 됨으로써, 타이어의 내구성을 향상시키는 효과가 있다.Therefore, the diameter d of the wire 2b at both side portions B of the belt 1 is molded to be smaller than the diameter Φ 2 of the wire 2a at the center portion A, whereby it is wound on the tire. When the stress concentration is the greatest, the durability of the tire shoulder portion is to be further improved. As described above, according to the present invention, since the shoulder portion of the tire receives less stress while driving, there is an effect of improving the durability of the tire.
