본 발명은 자동창용 타이어에 관한 것으로, 특히 트레드의 양측 에지부에 방열홈을 형서시키므로서 벨트에서 발생하는 열을 신속히 방열시켜 벨트의 분리현상을 감소시키므로서 타이어의 주행 내구성을 향상시킬 수 있도록 한 타이어에 관한 것이다.The present invention relates to a tire for an automatic window, and in particular, to form heat dissipation grooves at both edges of the tread to quickly dissipate heat generated from the belt to reduce the separation of the belt, thereby improving the running durability of the tire. It's about tires.
트레드부의 하측 카카스의 상부에 제1 및 제2벨트를 설치하여서 된 자동차용 래디알 타이어에 있어서는 주행에 의한 충격으로 벨트의 에지부분에 심한 응력이 발생하며 따라서 벨트의 에지부분에서는 심한 발열로 인하여 벨트가 분리되고 파손되는 현상이 발생한다. 그리하여 벨트의 분리를 방지하기 위하여 벨트의 에지부분에 카바를 설치한다던지, 발생하는 열을 신속히 방열시키기 위하여 적절한 방열 수단을 설치하지 않으면 안되는 것이다. 본 발명은 이러한 벤트 분리 방지 수단중 방열효과를 증진시킬 수 있는 수단을 제공할 수 있도록 한 것으로 특히 타이어에 일반적으로 설치되어 있는 횡그루브상에 벨트의 에지부분을 향하여 벨트와의 거리가 약1~4㎜에 이르기 까지 방열홈을 형성시키므로서 방열홈을 통하여 벨트의 에지부분에서 발생한 열이 방출되도록 한 것인 바, 이와 같은 본 발명은 첨부된 도면에 의하여 설명하면 다음과 같다.In the radial tires for automobiles in which the first and second belts are installed on the upper side of the lower carcass of the tread, severe stress is generated at the edge of the belt due to the impact caused by driving, and therefore, excessive heat is generated at the edge of the belt. The belt separates and breaks. Thus, in order to prevent the belt from being separated, a cover is installed at the edge of the belt, or an appropriate heat dissipation means must be installed to quickly dissipate heat generated. The present invention is to provide a means for improving the heat dissipation effect of the vent separation prevention means, in particular, the distance from the belt toward the edge portion of the belt on the horizontal groove generally installed in the tire is about 1 ~ The heat generated from the edge portion of the belt through the heat dissipation groove to form a heat dissipation groove up to 4mm bar as described above, the present invention will be described with reference to the accompanying drawings.
트레드부(1)의 양측에 사이드월(2)이 형성되고 사이드월(2)의 하단에 비드부(4)가 설치되며 트레드(1)의 하측 카카스(4)의 상부에 제1 및 제2의 벨트(5)가 설치되며 트레드(1)와 사이드월(2)이 접하여 지는 숄더(6)부에 세폭그루브(7)가 설치된 통상의 것에 있어서, 세폭그루브(7)에 방열홈(8)을 부가 설치한다. 방열홈(8)은 벨트(5)로부터 1~4㎜에 이르는 위치까지 이를 깊게 형성시키며, 방열홈(8)의 길이는 1~5㎜의 범위로 한다.Sidewalls 2 are formed on both sides of the tread portion 1, bead portions 4 are installed at the lower ends of the sidewalls 2, and the first and the second upper portions of the lower carcass 4 of the tread 1 are formed. In the usual case in which the narrow groove 7 is provided in the shoulder 6 where the belt 5 of 2 is provided and the tread 1 and the sidewall 2 contact each other, the heat groove 8 is provided in the narrow groove 7. Install additionally. The heat dissipation groove 8 is formed deeply from the belt 5 to a position ranging from 1 to 4 mm, the length of the heat dissipation groove 8 is in the range of 1 to 5 mm.
이러한 방열홈의 위치는 상술한 바와 같이 벨트(5)의 에지부분이나, 타이어의 외형상 트레드(1)와 사이드월(2)이 만나는 지점인 P-Point를 기준으로 하여 트레드폭의 10% 범위 내에 위치하게 한다. 타이어의 숄더부위에 세폭그루브(7)를 형성시키려면 가류금형에 제2도에서 보는 바와 같은 블레이트(9)를 설치하는 것이 바람직한데, 본 발명의 방열홈(8)을 형성시키기 위하여는 이러한 블레이드(9)에 소정크기의 돌출부(91)를 형성시키므로서 쉽게 그 목적을 달성할 수 있다.The position of the heat dissipation groove is 10% of the tread width based on the edge portion of the belt 5 or the P-Point where the tire tread 1 and the sidewall 2 meet as described above. To be located inside. In order to form the narrow groove 7 in the shoulder portion of the tire, it is preferable to install the blade 9 as shown in FIG. 2 in the vulcanization mold, in order to form the heat dissipation groove 8 of the present invention. By forming the protrusions 91 of a predetermined size on the blade 9, the purpose can be easily achieved.
타이어의 숄더부위에 세폭그루브(7)를 다수 형성시키게 되면 강성이 저하되어 핸들링성능에 영향을 미치게 된다. 따라서 본 발명에 있어서의 방열홈(8)은 숄더부의 강성과 조정안정성에 영향을 줄 수 있으므로 세폭그루브(7)의 길이 및 갯수등의 설계에 있어서는 그만큼의 고려가 있어야 한다. 그러나 상술한 정도의 규격을 갖는 방열홈(8)을 약 30~70개 형성 시킨 경우에 있어서는 핸들링 성능의 별다른 감소 없이 방열효과를 향상시키어 주행내구성을 향상시킬 수 있음을 알았다.When a large number of narrow grooves 7 are formed in the shoulder portion of the tire, the rigidity is lowered and affects the handling performance. Therefore, since the heat dissipation groove 8 in the present invention may affect the stiffness and adjustment stability of the shoulder portion, such a design should be considered in the design of the length and number of the narrow grooves 7. However, in the case where about 30 to 70 heat dissipation grooves 8 having the above-described specifications are formed, it is found that the driving durability can be improved by improving the heat dissipation effect without any decrease in handling performance.
