Description

젖은노면에서 견인력을 향상시킨 타이어{Tire with wet traction}Tire with improved traction on wet roads {Tire with wet traction}

본 발명은 트레드 블럭 내부에 높은 강성의 강성재를 채택하여 젖은노면에서 웨트 트랙션(Wet traction)이 향상되어 안전주행에 도움이 되는 견인력을 향상시킨 타이어에 관한 것이다.The present invention relates to a tire that adopts a high rigidity stiffness inside the tread block to improve wet traction on wet roads, thereby improving traction.

수막 위를 주행하는 타이어가 임계속도를 넘게 되면 타이어와 노면 간의 접촉이 분리되어 물 위에 뜨게 되는 현상이 발생하게 되는데 이를 수막현상이라 한다.When the tire running on the water surface exceeds the critical speed, the contact between the tire and the road surface is separated and floats on the water. This is called a water film phenomenon.

이 경우 지면과의 접촉력을 잃어버린 타이어는 차량이 정상적인 주행을 하기 위해 필요한 제어력을 제공할 수 없게 되어 대형사고를 초래할 수 있다.In this case, a tire that has lost contact with the ground may not provide the control necessary for the vehicle to drive normally, which may cause a serious accident.

높은 수막 성능은 타이어가 물 위에 뜨게 되는 임계속도를 높여 줌으로써 달성될 수 있는데, 이는 배수성능에 영향을 주는 패턴 및 프로파일 등의 기하학적 인자들을 조절함으로써 가능하다.High water film performance can be achieved by increasing the critical speed at which tires float on the water, by adjusting geometric factors such as patterns and profiles that affect drainage performance.

따라서 종래에는 수막성능을 향상시키기 위해서 주로 트레드의 패턴형상을 변경시키는 방법을 이용하거나, 그루브의 깊이를 보강벨트의 위치까지 내려오게 하여 더 깊은 그루브를 갖는 타이어를 제조하는 방법, 혹은 그루브 내의 무늬와 홈을 파는 등의 방식을 이용해 성능향상을 도모해 왔다.Therefore, conventionally, in order to improve water film performance, a method of changing a tread pattern shape is mainly used, or a method of manufacturing a tire having a deeper groove by lowering the depth of the groove to the position of the reinforcing belt, or a pattern in the groove. The performance has been improved by digging grooves.

트레드 부의 패턴형상을 변경하게 되면 시간과 금전적인 측면에서 큰 비용을 지불해야 하기 때문에 효율이 떨어지게 된다. 또한, 그루브의 깊이를 보강벨트의 위치까지 내려오게 하는 방식은 현 제조방식의 변경에 따른 문제와 보강벨트층이 그루브를 만나게 되면 서로 떨어져 있는 것으로 인해 타이어 원주방향으로의 강성이 떨어질 우려가 있게 된다. Changing the tread pattern's shape is less efficient because it costs a lot of time and money. In addition, the method of bringing the depth of the grooves down to the position of the reinforcing belt is a problem due to the change of the current manufacturing method and when the reinforcing belt layer meets the groove, the stiffness in the circumferential direction of the tire may decrease due to being separated from each other. .

그리고 그루브 내의 무늬나 홈을 파는 등의 방식에 있어서는 배수능력을 촉진시키는 방법을 사용하게 되나 종래의 방식들은 지면과 접하는 타이어와 접지면에서의 근본적인 접지 문제를 해결하는 방식은 아니고 단순히 배수능력을 향상시키기 위한 방법이었다.And in the way of digging or groove in the groove, the method of promoting drainage capacity is used. However, the conventional methods do not solve the fundamental problem of grounding on the tire and the ground contacting the ground, but simply improve the drainage capacity. It was a way to make it.

이에 본 발명은 젖은노면에서 타이어의 웨트 트랙션을 높이어 젖은노면과의 견인력 효과가 증가됨에 따라 안전주행에 도움을 주는 타이어를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a tire that helps to drive safely as the wet traction on the wet road increases the traction effect with the wet road.

이와 같은 목적을 달성하기 위한 본 발명은 그루브와 블럭이 형성된 트레드를 구비한 타이어에 있어서, 상기 트레드의 블럭 내부에는 높은 강성을 갖는 스티프니스(Stiffness)를 위치시키되, 이 시티프니스는 블럭 내에 형성된 사다리꼴 홈에 밀착 고정되는 사다리꼴 형태의 구조물로 되어 있다.In order to achieve the above object, the present invention provides a tire having a tread formed with a groove and a block, wherein a stiffness having a high rigidity is placed inside the block of the tread, and the cityness is trapezoidal formed in the block. It has a trapezoidal structure that is tightly fixed to the groove.

상기와 같이 본 발명에 따른 젖은노면에서 견인력을 향상시킨 타이어는 젖은노면과 접촉하는 블럭에 스티프니스 구조물을 갖춤에 따라 타이어의 웨트 견인력(Wet traction)이 향상되어 안전주행에 도움을 준다.As described above, the tire having improved traction in the wet road surface has a stiffness structure in the block in contact with the wet road surface, thereby improving the wet traction of the tire, thereby helping to drive safely.

이하, 본 발명의 바람직한 실시예를 도면을 참고로 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

도 1은 본 발명에 따른 타이어의 부분 단면도이다.1 is a partial cross-sectional view of a tire according to the present invention.

본 발명은 젖은노면에서 견인력을 향상시키기 이한 트레드를 갖춘 타이어로서, 도면에 도시된 바와 같이 그루브(1)와 블럭(2)이 형성된 트레드(3)를 구비한 타이어에 있어서, 상기 트레드(3)의 블럭(2) 내부에는 높은강성을 갖는 스티프니 스(4)가 삽입되되, 이 스티프니스(4)는 블럭(2) 내에 형성된 사다리꼴 홈(5)에 밀착 고정되는 구조체로 되어 있다.The present invention relates to a tire having a tread for improving traction on a wet road, and has a tread (3) having a groove (1) and a block (2) as shown in the drawing, wherein the tread (3) A stiffness 4 having a high rigidity is inserted into the block 2 of the stiffness 4, and the stiffness 4 is a structure that is tightly fixed to the trapezoidal groove 5 formed in the block 2.

여기서 상기 스티프니스(4)는 주행 중 트레드(3)의 변형으로 인해 블럭(2)의 사다리꼴 홈(5)에서 약간 돌출될 수 있도록 블럭(2)과 연결되는 양쪽 부위에 간격홈(6)을 유지하면서 블럭(2) 내에 삽입 고정된다.Here, the stiffness 4 maintains the gap grooves 6 at both portions connected to the block 2 so that the stiffness 4 may protrude slightly from the trapezoid groove 5 of the block 2 due to the deformation of the tread 3 while driving. It is inserted into and fixed in the block 2.

이에 따라 노면과 접촉되는 트레드(3)의 블럭(2)은 벤딩(Bending)을 받게 되고, 노면에 접촉된 트레드(3)의 블럭(2)은 압축변형을 받는데, 노면과 비접촉되는 트레드(3)의 블럭(2)은 인장변형이 동시에 된다.Accordingly, the block 2 of the tread 3 in contact with the road surface is subjected to bending, and the block 2 of the tread 3 in contact with the road surface is subjected to compression deformation, and the tread 3 is in contact with the road surface. The block 2 of) becomes tensile strain at the same time.

이로 인해 블럭(2)의 압축변형을 받는 부위가 도 1의 화살표 방향으로 안쪽으로 밀려들어가게 되고, 상대적으로 강한 강성을 갖는 스티프니스(4)는 바깥쪽으로 약간 돌출되는 효과를 갖는다.As a result, the portion subjected to the compression deformation of the block 2 is pushed inward in the direction of the arrow in FIG. 1, and the stiffness 4 having a relatively strong rigidity has an effect of slightly protruding outward.

또한, 도 2 (B)와 같이 노면과 접촉하는 타이어의 블럭(2)은 편평하게 퍼지게 되고, 도 2 (A)와 같이 노면과 닿지 않은 비접촉 트레드(3)의 블럭(2)은 곡률 형상을 지니게 된다.In addition, as shown in FIG. 2B, the block 2 of the tire in contact with the road surface spreads flatly, and the block 2 of the non-contact tread 3 not contacting the road surface as shown in FIG. 2A has a curvature shape. Will be carried.

따라서 본 발명에 따른 타이어는 젖은노면에서 노면과 접촉하는 트레드(3)의 블럭(2) 내에 있는 시티프니스(4)가 사다리꼴 홈(5) 내에서 약간 돌출되어 튀어나온 구조물로 유지되어 젖은노면의 물살을 가르는 기능을 갖춤과 동시에 젖은노면과의 견인력 효과를 증대시키도록 되어 있다.Accordingly, in the tire according to the present invention, the wetness surface is maintained as a structure in which the city fitness 4 in the block 2 of the tread 3 which contacts the road surface on the wet road surface slightly protrudes in the trapezoidal groove 5. It is equipped with the function of dividing the water and increases the traction effect with wet roads.
