본 발명은, 공기압 부족 표지를 가진 자동차용 공기입 타이어를 제공하기 위한 것이다.The present invention is to provide a pneumatic tire for a vehicle having a pneumatic deficiency mark.

공기입 자동차용 타이어에 있어서는 차량의 하중을 지지하기 위하여 타이어 내부 공기압을 적정하게 유지시키는 일이 중요하다. 만일 타이어에 공기압이 부족하게 될 경우, 타이어에 과부하가 걸리게 되고 이로 인한 타이어에 과열이 발생되어 차량 안전사고의 원인이 되기도 한다.In pneumatic vehicle tires, it is important to properly maintain the tire pressure inside the tire to support the load of the vehicle. If the tire lacks air pressure, the tire may be overloaded, resulting in overheating of the tire, which may cause vehicle safety accidents.

그리하여 타이어가 내부의 공기압을 일정하게 유지하지 못하는 경우에 있어서의 사고를 방지하기 위하여 런-플랫(Run-flat)타이어를 제공하는가 하면, 타이어의 공기압이 부족할 경우 사용자에게 경고를 해 주는 장치가 제공되기도 하였다. 그러나, 이와 같은 런플랫타이어나 경고장치는 가격이 고가이며 이미 출시된 차량에서는 사용이 곤란한 결점이 있다.Thus, a run-flat tire is provided to prevent an accident in case the tire cannot keep the air pressure constant inside, or a device that warns the user when the tire pressure is insufficient. It also became. However, such run flat tires and warning devices are expensive and have difficulty in being used in already released vehicles.

이에 본 발명은, 타이어에 공기압이 부족하면 타이어의 접지 면적이 확대된다는 점에 주목하고, 접지 면적의 확대시 추가 접촉되는 부위인 숄더부에 표지를 형성시킴으로서, 타이어의 공기압이 낮아지면 숄더부의 표지가 지면에 접촉되게 하여 타이어의 공기압 부족을 용이하게 인식할 수 있게 한 것인 바, 이와 같은 본 발 명을 첨부된 도면에 의하여 설명하면 다음과 같다.Therefore, the present invention is noted that when the tire lacks air pressure, the ground area of the tire is enlarged, and by forming a mark on the shoulder portion, which is an additional contact area when the ground area is enlarged, the mark of the shoulder portion is reduced when the tire air pressure is lowered. Is to make it easy to recognize the lack of air pressure of the tire by contacting the ground, this invention will be described with reference to the accompanying drawings as follows.

트레드(1) 사이드(2)월 및 비드부(3)로 구성되는 타이어에 있어서, 본 발명은 공기 누출로 인하여 접지부가 확대될 경우, 추가 접촉되는 부위인 숄더부(4)에 표지(5)를 설치하는 것을 특징으로 한다.In the tire composed of the tread (1) side (2) wall and the bead part (3), the present invention is a mark (5) on the shoulder part (4), which is an additional contact area when the ground part is enlarged due to air leakage. Characterized in that the installation.

표지(5)는 다양한 색과 모양을 가지도록 형성시킴으로서 시각에 의한 공기누출 감지를 용이하게 할 수 있으며, 그 설치 수를 증대시켜 설치 효과를 증대시킬 수 있음은 물론이다.The cover 5 may be formed to have a variety of colors and shapes to facilitate the detection of air leakage by sight, and the number of installations thereof may be increased to increase the installation effect.

표지(5)를 구성하는 물질은 숄더부(4)를 구성하는 물질과 상이하게 형성시킨다던지, 표지(5)가 돌출 또는 함몰되게 형성시킴으로서, 공기압 부족의 상태에서 타이어의 주행시 표지(5)가 지면에 접촉되면 추가적인 소음이 발생하게 하는 것이 바람직하다. 표지(5)를 구성하는 물질은 합성수지, 합금, 세라믹 및 강화플라스틱 등 숄더부(4)를 구성하는 물질과 3배 이상의 경도 차이를 가지는 것으로 형성시킬 수 있으며, 이와 같은 경우, 주행시에 있어서의 소음 정도가 커질 수 있다.The material constituting the mark 5 is formed differently from the material constituting the shoulder portion 4, or the mark 5 is formed to protrude or dent so that the mark 5 when the tire is running in a state of insufficient air pressure is formed. It is desirable to cause additional noise when in contact with the ground. The material constituting the cover 5 may be formed to have a hardness difference of three times or more from the material constituting the shoulder portion 4 such as synthetic resin, alloy, ceramic, and reinforced plastic, and in such a case, noise during driving The degree can be greater.

숄더부(4)에 있어서, 표지(5)를 설치하는 위치는 접지면으로부터 휠까지의 높이(H)의 5∼30%의 범위 내인 것이 바람직하다.In the shoulder part 4, it is preferable that the position in which the mark 5 is provided is in the range of 5 to 30% of the height H from the ground plane to the wheel.

또한, 표지(5)는 이를 여러 단으로 구성시키고, 각 단에 위치하는 표지(5)의 크기를 접지면으로부터 멀어질수록 점점 크게 형성시킴으로서 공기압의 저하 정도가 클수록 소음의 정도가 커지게 형성시킬 수 있다.In addition, the cover (5) is composed of several stages, and the size of the cover (5) located in each stage is formed larger and larger as the distance away from the ground plane so that the degree of noise increases as the degree of decrease in air pressure increases. Can be.

이와 같이 구성된 본 발명은, 공기압의 저하시 표지(5)가 지면에 가까워지거나 지면에 접촉되어, 시각적인 감지를 용이하게 하거나 소음의 발생으로 인한 청각적 감지가 가능하게 되어 공기압 부족에도 불구하고 고속 주행을 하는 경우에 있어서의 사고 위험을 감소시킬 수 있는 효과가 있다.According to the present invention configured as described above, when the air pressure decreases, the mark 5 comes close to or comes into contact with the ground, thereby facilitating visual sensing or audible sensing due to the generation of noise, thereby allowing high speed despite the lack of air pressure. There is an effect that can reduce the risk of accidents when driving.
