본 고안은, 숄더부위를 보강하여서 된 자동차용 타이어에 관한 것이다.The present invention relates to an automobile tire made by reinforcing a shoulder portion.

숄더부위가 장애물과의 충돌로 손상되는 것을 방지하기 위하여, 첨부된 도면 도 2 에 도시된 바와 같이, 숄더부 부위 내측에 직 보강층을 설치하여서 된 타이어가 제공된 바 있다. 그러나, 이와 같은 종래의 타이어는 타이어의 굴신 작용시 보강층이 숄더부에 심한 스트레스를 가하여 숄더부에 균열을 야기할 염려가 클 뿐 아니라, 이러한 보강층은, 차량의 운행 중, 트레드부 내부에 발생한 열이 밖으로 나오는 것을 차단하여 숄더부가 고열에 의해 물성이 약화되고 그리하여 숄더부가 쉽게 손상되는 결점이 있다. In order to prevent the shoulder portion from being damaged by a collision with an obstacle, as shown in the accompanying drawings, Figure 2 has been provided with a tire by installing a straight reinforcement layer inside the shoulder portion. However, such a conventional tire not only has a high risk that the reinforcement layer exerts severe stress on the shoulder portion and causes cracks in the shoulder portion when the tire is stretched, and such a reinforcement layer is heat generated inside the tread portion during the driving of the vehicle. There is a drawback of preventing this from coming out so that the shoulder portion is weakened by high heat and thus the shoulder portion is easily damaged.

이에, 본 고안은, 종래에 있어서와 같이, 타이어의 숄더부 내측에 보강층을 설치하되, 보강층을 다단으로 분할 형성시키고, 분할된 각 단이 갑옷이나 비늘처럼 겹쳐지게 그러나 각 단이 간격을 두고 설치되게 함으로서 굴신작용에 의해 보강층이 숄더에 가하는 스트레스를 감소시키고, 나아가, 분할된 각 보강층의 간극으로 트레드 내부의 열이 외부로 발산될 수 있게 한 것인 바, 이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.Thus, the present invention, as in the prior art, to install a reinforcing layer inside the shoulder portion of the tire, the reinforcing layer is formed in multiple stages, each divided stage is overlapped like armor or scales but each stage is spaced apart By reducing the stress applied to the shoulder by the reinforcement layer by the stretching action, and further allows the heat inside the tread to be dissipated to the outside by the gap of each divided reinforcement layer, this invention is attached to the accompanying drawings By explaining it is as follows.

트레드(1)와 사이드월 및 비드부로 구성되고, 트레드와 사이드월이 만나는 부위인 숄더부(2) 내부에 보강층을 형성시켜서 된 것에 있어서, 보강층을 다수개의 분할보강층(31, 32, 33, 34)으로 분할 형성시키되, 각각의 분할보강층(31, 32, 33, 34)을 다단으로 분할 형성시키며, 분할되어 서로 이웃하는 각 단을 갑옷이나 비늘처럼 서로 겹쳐지게 설치하고, 그러나, 그 겹침부위가 분할보강층(31, 32, 33, 34)의 직각 방향으로 겹쳐지게 설치하며, 겹쳐지더라도 그 겹침 사이에 간격을 형성시켜 각 분할보강층(31, 32, 33, 34) 사이에 이격부(4)가 형성되게 한다. 이격부(4)의 간극은 분할보강층(31, 32, 33, 34) 중 한개 층 두께의 1∼3배가 되게 형성시키는 것이 바람직하다.The reinforcement layer is formed of the tread 1, the sidewall and the bead portion, and the reinforcement layer is formed inside the shoulder portion 2, which is a portion where the tread and the sidewall meet each other, and the reinforcement layer is divided into a plurality of reinforcement layers 31, 32, 33, 34. The split reinforcement layer (31, 32, 33, 34) is divided into multiple stages, and each stage is divided and installed adjacent to each other like armor or scales, but the overlapped portion is The split reinforcing layers 31, 32, 33, 34 are installed so as to overlap each other in a direction perpendicular to each other, and even if overlapping, forming a gap between the overlapping reinforcing portions (31) between each of the divided reinforcing layers (31, 32, 33, 34) To be formed. It is preferable that the gap between the separation portions 4 is formed to be one to three times the thickness of one of the divided reinforcement layers 31, 32, 33, and 34.

각 분할보강층(31, 32, 33, 34)은 이들이 서로 평행한 방향으로 설치시키되, 지면에서 외부의 충격에 의해 사고가 발생하기 쉬운 각도라고 알려 진 각도인 수직방향으로부터 15∼50도의 경사를 갖도록 설치하는 것이 바람직하다.Each divided reinforcement layer 31, 32, 33, 34 is installed in a direction parallel to each other, so as to have an inclination of 15 to 50 degrees from the vertical direction, which is an angle known to be easy to cause accidents by external impacts on the ground. It is desirable to install.

그리고, 숄더부(2) 외표면에는 굴곡부(5)를 형성시키어, 외표면적을 확대시킴으로서 트레드(1)부의 열을 더욱 용이하게 발산시키게 하는 것이 바람직하다.In addition, it is preferable that the bent portion 5 is formed on the outer surface of the shoulder portion 2 to enlarge the outer surface area so that the heat of the tread 1 portion is more easily dissipated.

이와 같이 구성된 본 고안은, 타이어의 숄더부 내측에 보강층을 설치하되, 보강층을 다단으로 분할 형성시키고, 분할된 각 단이 갑옷이나 비늘처럼 겹쳐지게 그러나 각 단이 간격을 두고 설치되게 함으로서 굴신작용에 의해 보강층이 숄더에 가하는 스트레스를 감소시키고, 나아가, 분할된 각 보강층의 간극으로 트레드 내부의 열이 비교적 용이하게 외부로 발산될 수 있는 효과가 있으며, 나아가, 숄더부 표면에 형성시킨 굴곡부(5)가 트레드의 열 발산 효과를 증진시키는 효과가 있다.The present invention configured as described above, the reinforcement layer is installed inside the shoulder portion of the tire, the reinforcement layer is divided into multiple stages, and the divided stages are overlapped like armor or scales, but the stages are spaced apart so that they can be stretched. As a result, the stress applied to the shoulder by the reinforcing layer is reduced, and furthermore, the heat inside the tread can be dissipated to the outside relatively easily by the gap between the divided reinforcing layers, and further, the bent part 5 formed on the shoulder surface Has the effect of enhancing the heat dissipation effect of the tread.
