Description

차량용 공기입 타이어{Pneumatic vehicle tire}[0001] Pneumatic vehicle tire [0002]

본 발명은 차량용 공기입 타이어에 관한 것으로, 특히 중하중용 타이어에 있어서, 접지면에서 받는 응력을 효과적으로 분산시킬 수 있는 커프(kerff)의 기술에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic tire for a vehicle, and more particularly to a technique of a kerff capable of effectively dispersing stress received from a ground surface in a heavy duty tire.

자동차용 일반적으로 타이어의 트레드면은 블록 및 그루브로 구성되어 있는 바, 타이어의 블록에는 트랙션(Traction) 및 제동력을 향상시키기 위하여 커프(Kerf)를 형성시키게 된다. 또한, 상기 커프는 블록의 강성을 적절히 조절하여 타이어가 가지는 요구성능을 만족시켜 왔다.Generally, a tread surface of a tire is composed of blocks and grooves, and a tread and a cuff are formed on the tire to improve braking and traction. Further, the cuff satisfactorily satisfies the required performance of the tire by appropriately adjusting the rigidity of the block.

특히, 중하중용 공기압 타이어에서 커프(Kerf)는 높은 하중에 따른 응력 집중을 효과적으로 막기 위해 적용되어 진다. 종래의 커프들은 접지면에 대하여 수직방향으로만 형성되어 주행방향에 대하여 횡방향으로의 응력만을 분산시킬 수 있었다. 그러나, 중하중용 타이어와 같은 하중의 변화에 민감한 타이어 경우에는 횡방향과 종방향의 힘을 동시에 받는 경우 두 방향의 힘의 고른 분산이 필요하다. In particular, in heavy-duty pneumatic tires, the cuff is applied to effectively prevent stress concentration due to high loads. Conventional cuffs were formed only in the vertical direction with respect to the ground plane, so that only the stress in the lateral direction with respect to the running direction could be dispersed. However, in the case of a tire sensitive to changes in load such as heavy duty tires, it is necessary to uniformly distribute the forces in both directions when the lateral and longitudinal forces are simultaneously applied.

종래의 커프들은 그 종단면이 지그재그 형태로 구성되어 위와 같은 응력의 분산효과를 부분적으로 얻을 수 있었으나, 본 발명에서는 보다 향상된 성능의 응력분산 커프기술을 제공하고자 한다.
Conventional cuffs are formed in a zigzag shape in their longitudinal sections to partially achieve the above-described effect of dispersing stress, but the present invention intends to provide a stress-dispersion cuff technique with improved performance.

즉, 하중의 변화에 민감한 중하중용 타이어에 있어서, 주행방향에 대하여 횡방향 뿐만 아니라 주행방향에 대하여 종방향의 응력도 효과적으로 분산시킬 수 있는 커프형성 기술이 필요한 것이다.
That is, in a heavy duty tire sensitive to a change in load, a cuff forming technique capable of effectively dispersing not only the lateral direction but also the longitudinal direction stress with respect to the running direction is required for the running direction.

이에 본 발명은, 타이어의 블록(4)에 커프(6)가 형성되는 것에 있어서, 상기 커프(6)는 트레드면에 대해 수직으로 형성된 수직커프(61)와, 상기 수직커프(61)을 연결하며 트레드면에 대해 평행하게 형성된 수평커프(62)로 구성된 커프를 제시하여 주행방향에 대하여 종방향의 응력도 효과적으로 분산시킬 수 있는 커프형성 기술을 제공하고자 한다.
The present invention is characterized in that a cuff 6 is formed on a block 4 of a tire, and the cuff 6 includes a vertical cuff 61 formed perpendicular to the tread surface, And a horizontal cuff 62 formed parallel to the tread surface, thereby effectively dispersing the longitudinal stress in the running direction.

본 발명에 따르면 주행방향에 대하여 종방향의 응력도 효과적으로 분산시킬 수 있다. 또한, 수직커프의 깊이와 수평커프의 길이를 2중으로 구성하여 큰 응력이 걸리게 되면 대(大)깊이/길이의 커프가 이에 대응되어 응력을 해소시키게 되고, 작은 응력이 걸리게 되면 소(小)깊이/길이의 커프가 이에 대응되어 응력을 해소시키게 된다.According to the present invention, it is possible to effectively disperse the longitudinal stress in the running direction. Further, when the vertical cuff depth and the length of the horizontal cuff are configured to be two and a large stress is applied, the cuff of the large depth / length corresponds to the stress so that the stress is relieved. When a small stress is applied, / Cuff of the length corresponds to this, thereby relieving the stress.

즉 본 발명에 의하면 주행방향에 대하여 종방향의 응력도 효과적으로 분산시킬 뿐 아니라, 응력의 크기에 따른 대응되는 깊이(길이)의 커프를 형성시킴으로써 응력의 크기에 따른 효과적인 분산효과도 기대할 수 있는 것이다.
That is, according to the present invention, not only the longitudinal stress is effectively dispersed in the running direction but also the cuff having the corresponding depth (length) according to the magnitude of the stress is formed, so that an effective dispersion effect according to the magnitude of the stress can be expected.
