배토성을 향상시켜서 된 자동차용 타이어{Vehicle tire improved mud extraction performance}Vehicle tire improved mud extraction performance

본 발명은 비포장 도로(Off-Road)용 공기입 타이어에 있어서, 타이어의 그루브에 진흙이 끼어 주행 성능이 저하되는 것을 방지하기 위하여 배토성을 향상시켜서 된 타이어를 제공하기 위한 것이다.SUMMARY OF THE INVENTION The present invention provides an inflated tire for off-road pavement, in which dirt is improved in order to prevent dirt from getting stuck in grooves of the tire and deteriorating running performance.

SUV(Sports Utility Vehicle)나 사륜구동용 자동차는 비포장 도로를 주행하는 경우가 있으므로 이러한 차량에 장착되는 타이어에는 진흙 배출 성능이 좋은 타이어가 필요하게 된다. Since a sports utility vehicle (SUV) or a four-wheel drive vehicle may drive on a dirt road, tires mounted on such vehicles require tires having good mud discharge performance.

원래, 타이어에는 주행 성능 특히 구제동 성능을 향상시킬 수 있도록 하기 위하여 타이어의 표면에 다양한 형태의 그루브를 설치하고 있는 바, 이러한 그루브는 일반적으로 동일한 폭과 경사벽으로 형성되어 있으므로, 그루브 내에 진흙이 끼이게 되면, 그루브 내에 끼인 진흙이 잘 배출되지 않아 구제동 및 코너링 성능이 현저히 둔화되어 차량의 주행 성능이 떨어지는 경향이 있었다. Originally, tires are provided with various types of grooves on the surface of the tire to improve driving performance, especially braking performance. Since such grooves are generally formed with the same width and inclined walls, mud in the grooves When caught, the mud trapped in the grooves was not discharged well, and the braking and cornering performances were significantly slowed, leading to a deterioration of the driving performance of the vehicle.

이에 본 발명은, 비포장 도로에서의 주행 필요가 큰 차량에 장착되는 타이어에 있어서는 진흙 물림을 용이하게 제거할 수 있는 타이어를 제공하여야 한다는 과제를 해결하고자 한다.Accordingly, the present invention aims to solve the problem of providing a tire that can easily remove mud bites in a tire mounted on a vehicle having a large need for traveling on an unpaved road.

위와 같은 과제를 해결하기 위하여 본 발명은 블록의 피치 단위로 형성되는단위 그루브에 있어서 그루브의 폭과 경사각을 점진적으로 변화되게 형성시켜서 된 타이어를 제공한다.In order to solve the above problems, the present invention provides a tire formed by gradually changing the width and the inclination angle of the groove in the unit groove formed by the pitch unit of the block.

이와 같은 본 발명은, 블록의 피치 단위로 그루브의 폭과 경사가 가변되도록 설정되어 있으므로, 단위 그루브와 이에 이웃하는 그루브 사이의 연속성을 깨트려 피치 단위로 그루브 내에 끼인 진흙의 무게 중심 및 힘의 방향에 변화를 주게 되어 진흙이 전 원주상으로 연속되어 붙어있지 않고 피치 단위로 절단되어 배토 성능이 향상되게 하는 효과가 있다. 특히, 본 발명은, 주행시 그루브 벽의 움직임에 의한 펌핑 작용으로 그루브에 끼인 진흙이 용이하게 배출되는 효과가 있다.     Since the present invention is set such that the width and the inclination of the groove are variable in the pitch unit of the block, the direction of the center of gravity and the force of the mud sandwiched in the groove in the pitch unit by breaking the continuity between the unit groove and the neighboring groove. The mud is not attached to the entire circumference continuously but is cut in pitch units, thereby improving the clay performance. In particular, the present invention, there is an effect that the mud caught in the grooves is easily discharged by the pumping action by the movement of the groove wall when running.
