Abstract

A pneumatic tire for a vehicle is provided to employ the secondary inner liner layer between a shoulder part and a side part to reduce the width of the secondary inner liner layer, and form only the first inner liner layer between a thread central portion and a bead lower end to reduce the weight of the tire. The pneumatic tire includes a thread(1), a sidewall(2), and a bead part(3). A belt(4) is installed in the lower portion of the thread. A carcass is installed in the lower portion of the sidewall. A bead filler of the bead part of the kakas is turned to the outer upper portion. The first and second inner liners are installed in the kakas. Two opposite ends of the secondary inner liner are positioned at a point having a distance of 15mm from the end of the belt, and at a point having a distance of 5mm to 10mm from the lower end of the bead filler.

본 발명은 자동차용 공기입 타이어에 관한 것으로, 특히 인너라이너를 2개층으로 형성시켜서 된 타이에의 개량에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pneumatic tires for automobiles, and more particularly, to an improvement in a tie formed by forming an inner liner in two layers.

종래에는 내외측의 인너라이너가 공히 그 양단이 비드부를 감싸도록 형성시켜 왔으나, 본 발명은 내측의 2차 인너라이너의 적용범위를 감소시킴으로서 원가를 절감하며 타이어의 중량을 감소시켜 연비를 향상시킬 수 있는 타이어를 제공하기 위한 것이다.In the past, the inner liner of the inner and outer sides have been formed so as to surround the bead portion, but the present invention can reduce the cost of the inner inner liner by reducing the cost and reduce the weight of the tire to improve the fuel economy. It is to provide a tire.

일반적으로, 타이어의 내부 표면층을 이루는 1차 인너라이너는 내공기투과성이 큰 조성물로 형성시켜 카이어 내부 공기압을 유지시켜 주는 역할을 하고, 그 내측의 2차 인너라이너는 카카스코드층으로 고무가 침투하는 것을 방지하기 위해서 사용되었다. 종래에는 내외측의 인너라이너가 공히 그 양 끝단이 비드부를 감싸도록 형성시켜 왔다. 그러나 완성된 타이어에 있어서, 인너라이너가 차지하는 중량의 비율이 커서 타이어의 중량을 무겁게 하여 연비를 저하시키는 문제가 있었다. In general, the primary inner liner constituting the inner surface layer of the tire is formed of a composition having high air permeability to maintain the internal air pressure of the tire, and the inner inner liner inside the tire is a carcass cord layer. It was used to prevent penetration. Conventionally, inner and inner liners have been formed such that both ends thereof surround the bead portion. However, in the finished tire, there is a problem that the proportion of the weight of the inner liner is so large that the weight of the tire is heavy and the fuel economy is reduced.

이에, 본 발명은 인너라이너를 2개층으로 형성시킨 타이어에 있어서, 내측의 2차 인너라이너 층을 변화량이 많은 숄더부와 사이드부 사이에 부분적으로 적용하여 그 폭을 감소시키고, 트레드 중앙부와 비드 하단부위에는 1차 인너라이너 층만 형성시킴으로써 타이어 중량을 감소시켜 차량 연비를 향상시키고 제조원가를 절감할 수 있는 타이어를 제공하는 것에 그 목적이 있다. Accordingly, the present invention, in the tire formed by the inner liner in two layers, the inner secondary inner liner layer is partially applied between the shoulder portion and the side portion with a large amount of change to reduce the width, the tread center portion and the lower end of the bead The purpose is to provide a tire that can reduce the weight of the tire by forming only the first inner liner layer to improve vehicle fuel efficiency and reduce manufacturing cost.

이하, 첨부된 도면에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 트레드(1)와 사이드월(2) 및 비드부(3)로 구성되며, 트레드(1)의 저부에 벨트(4)가 설치되고, 상기 벨트(4)와 사이드월(2)의 저부에 카카스(5)가 설치되고, 카카스(5)의 말단부가 비드부(3)의 비드필러(31) 외측상부로 턴업되며, 카카스(5)의 내면에 2차인너라이너(6)와 1차인너라이너(7)가 설치된 것에 있어서, 2차 인너라이너(6)의 양측 단부가, 벨트(4)의 단부로부터 내측 15mm 지점(a)과 비드필러(31)의 끝단(310)의 하단 5~10 mm 지점(b)에 위치되게 형성시켜서 된 것을 특징으로 한다. The present invention comprises a tread (1), a sidewall (2) and a bead portion (3), and a belt (4) is provided at the bottom of the tread (1), and the belt (4) and the sidewall (2) of the The carcass 5 is provided at the bottom, the distal end of the carcass 5 is turned up to the outside of the bead filler 31 of the bead part 3, and the secondary inner liner 6 is formed on the inner surface of the carcass 5. ) And the primary inner liner 7, the both ends of the secondary inner liner 6 have an inner 15 mm point a and an end 310 of the bead filler 31 from the end of the belt 4. It is characterized in that it is formed to be located at the bottom 5 ~ 10 mm point (b).

이러한 구성은 주행 중 굴신운동에 의한 변화량이 많은 숄더부와 사이드부 사이에 부분적으로 적용하기 위함이다. This configuration is to partially apply between the shoulder portion and the side portion having a large amount of change due to the stretching movement during driving.

이상에서 설명한 바와 같이 본 발명에 따르면, 본 기술을 적용하면 종래의 타이어에 있어서와 같은 정도의 내구성 및 내공기 투과성을 유지하게 하면서도, 인너라이너용 고무의 양을 감소시켜 타이어의 제조비용을 감소시키며, 타이어 중량을 감소시켜 차량의 연비를 향상시킬 수 있는 효과가 있다.According to the present invention as described above, applying the present technology while maintaining the same durability and air permeability as in the conventional tire, while reducing the amount of rubber for the inner liner to reduce the manufacturing cost of the tire In addition, there is an effect that can improve the fuel economy of the vehicle by reducing the tire weight.
