본 고안은 카카스플라이를 가진 자동차용 공기입 타이어에 관한 것으로 특히 비드필러의 구조를 개량하므로서 충격을 완화시켜 승차감을 향상시키고 비드필러의 균열발생을 억제하여 내구성을 향상시킨 자동차용 타이어를 제공하기 위한 것이다.The present invention relates to a pneumatic tire for a car having a carcass splice, in particular, by improving the structure of the bead filler to reduce the impact to improve the ride comfort and to suppress the occurrence of cracks in the bead filler to provide an automobile tire for improved durability It is for.
자동차용 공기입 타이어의 비드부는 일반적으로 첨부된 도면 제1도에 도시된 바와 같이 비드와이어를 카카스플라이로 감싸되 비드와이어의 상측에 단면이 대략 원추형이고 비교적 높은 경도를 갖는 고무조성물로 된 비드필러를 설치하며 하측에는 체퍼를 설치하고 외측에는 림쿠션을 설치하여 형성시킨다. 그런데 높은 경도로 구성된 비드필러는 외력에 의한 사이드월부의 변형시 발생되는 굴신운동으로 인해 단위 표면적당 피로현상이 많이 발생되어 균열이 쉽게 발생되는 결점이 있다. 그리하여 종래에는 이러한 비드필러를 매우 강한 경도의 고무조성물로 형성시키거나 비드필러의 단면적을 크게하여 외력에 의한 굴신운동량을 작게하여 타이어의 내구성을 향상시키게 하였다. 그러나 이와 같이 비드필러의 굴신운동량을 억제시키면 필연적으로 승차감을 악화시키는 결점이 있었던 것이다. 그리하여 본 고안은 공기입타이어에 설치하는 비드필러의 형상을 종래의 있어서와 같이 그 단면이 원추형인 형상으로 형성시키지 아니하고 그 내외벽면을 파형으로 형성시키되 그 오목한 부분에는 비드필러를 구성하는 고무조성물 보다 낮은 경도의 고무조성물로 충전시켜 타이어가 외부로부터 충격을 받을 경우 비드필러가 그 충력을 용이하게 흡수하여 승차감을 향상시킬 수 있고 이러한 외력으로 비드필러가 굴신하는 경우 비드필러의 단위 표면적에 작용하는 굴신운동량을 상대적으로 작게 하여 즉 비드필러가 굴신하는 경우 내외측의 변형량을 작게하여 타이어의 내구성을 향상시킬 수 있게 한 것인바 이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.The bead portion of a pneumatic tire for a vehicle is generally a bead made of a rubber composition having a bead wire wrapped in a carcass splice and having a substantially conical cross section on the upper side of the bead wire and having a relatively high hardness, as shown in FIG. Fillers are installed and the lower side is equipped with a chafer and the outer rim cushion is formed. However, the bead filler composed of high hardness has a drawback that cracks are easily generated due to many fatigue phenomena per unit surface area due to the stretching motion generated during deformation of the sidewall by external force. Thus, in the related art, the bead filler is formed of a rubber composition having a very strong hardness, or the cross-sectional area of the bead filler is increased to reduce the amount of stretching movement caused by external force, thereby improving the durability of the tire. However, suppressing the amount of flexion momentum of the bead filler inevitably deteriorated ride comfort. Therefore, the present invention does not form the shape of the bead filler installed on the pneumatic tire in the shape of a conical section as in the prior art, and forms the inner and outer wall surfaces in a corrugated shape, but in the concave portion than the rubber composition constituting the bead filler. When the tire is impacted from the outside by filling with a rubber composition of low hardness, the bead filler can easily absorb the force and improve the riding comfort. When the bead filler is stretched by such external force, the flexure acts on the unit surface area of the bead filler. When the bead filler is relatively small, i.e., when the bead filler is stretched, it is possible to improve the durability of the tire by reducing the deformation amount of the inner and outer sides.
비드와이어(1)를 카카스플라이(2)로 감싸되 비드와이어(1)의 상측에 단면이 대략 원추형이고 비교적 높은 경도를 갖는 고무조성물로 된 비드필러(3)를 설치하며 하측에는 체퍼(4)를 설치하고 외측에는 림쿠션(5)을 설치하여 비드부를 형성시키는 자동차용 공기입 타이어에 있어서, 비드필러(3)의 내외벽면을 파형(31)으로 형성시키고, 파형(31)으로 형성시킨 벽면의 오목부에 비드필러(3)를 형성하는 고무조성물보다 낮은 경도의 고무조성물로된 충전고무(32)를 채워넣는다.The bead wire (1) is wrapped with a carcass splice (2), and a bead filler (3) made of a rubber composition having a substantially conical section and a relatively high hardness is installed on the upper side of the bead wire (1), and a lower chafer (4). In the pneumatic tire for automobiles in which a bead portion is formed by installing a rim cushion 5 on the outside, the inner and outer wall surfaces of the bead filler 3 are formed into a wave form 31, and the wave 31 is formed into a wave form 31. A filling rubber 32 made of a rubber composition having a hardness lower than that of the rubber composition forming the bead filler 3 is filled in the recess of the wall.
이와 같이 구성된 본 고안의 타이어는 타이머가 지면으로 부터의 외력을 받을때, 비드필러의 외벽이 파형으로 형성되어 있어 넓은 표면적을 갖게 되므로 그 충격을 보다 효과적으로 완충할 수 있어 승차감을 향상시킬 수 있으며, 그 외력에 의한 굴신은 넓은 표면적을 갖는 파형의 비드필러에서는 상대적으로 단위표면적당 굴신량이 작게되며, 따라서 많은 량의 굴신운동으로 인한 비드필러의 균열을 방지할 수 있어 타이어의 내구성을 향상시킬 수 있다.The tire of the present invention configured as described above has a large surface area because the outer wall of the bead filler is formed in a wave form when the timer receives an external force from the ground, so that the shock can be more effectively cushioned and the riding comfort can be improved. In the bead filler having a large surface area, the bending by the external force is relatively small in the amount of stretching per unit surface area, and thus it is possible to prevent cracking of the bead filler due to a large amount of stretching movement, thereby improving the durability of the tire.
