Abstract

PURPOSE: A pneumatic tire for preventing noise is provided to prevent wear by minimizing deformation of a horizontal groove from centrifugal force in cornering or applying high load, and to reduce noise and impact from the horizontal groove by forming an auxiliary block in the horizontal groove. CONSTITUTION: A vertical groove(2) and a horizontal groove(3) are formed in a tread part(1), and an auxiliary block(4) is formed in the horizontal groove. The auxiliary block is spaced from side walls of the horizontal groove to drain water through the horizontal groove. The outer periphery of the auxiliary block is inclined, and the height of the auxiliary block is formed to be as the height of the block. Deformation of the horizontal groove is minimized from the centrifugal force, and abnormal wear is prevented in mounting in a wide rim, applying high load or cornering excessively. Impact noise from the horizontal groove is restricted with forming the auxiliary block in contacting the horizontal groove to the road surface.

Description

노이즈 성능을 향상시킨 공기입 타이어 {Pneumatic tire for reduced noise}Pneumatic tire for reduced noise

본 발명은 노이즈 성능을 향상시킨 공기입 타이어에 관한 것으로서, 더욱 상세하게는 트래드패턴이 종그루브와 횡그루브가 복합적으로 형성되는 타이어에 있어서 숄더부에 형성되는 횡그루브가 노면과 접촉하며 발생시키는 임펙트노이즈를 억제시켜 노이즈 성능을 향상시킨 공기입 타이어를 제공하기 위한 것이다.The present invention relates to a pneumatic tire having improved noise performance, and more particularly, an impact caused by a lateral groove formed on a shoulder part in contact with a road surface in a tire in which a tread pattern is formed by a combination of longitudinal grooves and lateral grooves. It is for providing a pneumatic tire which suppresses noise and improves noise performance.

고속도로를 급히 달려가는 트럭의 뒤쪽에 가끔 있으면 '그아앙--' 이라고 들리는 대단한 소음이 발생된다. 이러한 소음의 대부분은 타이어에서 나오는 음이 차지하고 있다. 타이어가 러그 타입이라면 더한층 심하다.Occasionally in the back of a truck rushing down the highway, you'll hear a loud noise that sounds `` aah --- ''. Most of this noise comes from the tires. If the tire is a lug type, it is even worse.

옛날에는 도로의 포장율이 낮고 더구나 고속도로가 없던 때에는 타이어의 소음이 그다지 문제되지 않아 트럭용에는 경제적인 러그 타입의 트레드 모양이 전성기를 이루었다. 지금에 이르러 도로의 포장율이 나아지고 차량 수도 증가됨에 따라 차량의 소음 공해가 큰 문제가 되고 있다.In the past, the pavement of roads was low, and even when there was no highway, the noise of tires was not so much a problem. As the road pavement improves and the number of vehicles increases, noise pollution of vehicles becomes a big problem.

이와 같은 소음을 억제시키기 위하여 트래드의 폭을 작게 형성시키는 방법이 시도되고는 있으나, 트래드의 폭이 작게 형성되는 타이어의 경우 림의 폭이 크거나 고하중, 또는 코너링시에 접지부가 심하게 변형되어 이상 마모를 발생시키고, 심한 소음을 발생시키는 문제점이 있었다.In order to suppress such noise, a method of reducing the width of the tread has been attempted, but in the case of a tire having a small width of the tread, the rim has a large width, a heavy load, or the ground part is severely deformed during cornering. There was a problem of generating abrasion and severe noise.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 트래드패턴이 종그루브와 횡그루브가 복합적으로 형성되는 타이어에 있어서, 숄더부에 형성되는 횡그루브의 폭을 좁게 하지 않으면서도 횡그루브에서 발생되는 임펙트노이즈를 억제시켜 노이즈 성능을 향상시킨 공기입 타이어를 제공함에 그 목적이 있다.The present invention has been made to solve the above-described problems, the present invention is a tire in which the tread pattern is formed of a combination of longitudinal grooves and horizontal grooves, the horizontal grooves without narrowing the width of the horizontal grooves formed on the shoulder portion It is an object of the present invention to provide a pneumatic tire with improved noise performance by suppressing the impact noise generated in the.

본 발명은 상기와 같은 목적을 달성하기 위해서 다음과 같이 구성된다. 즉, 본 발명은 종그루브와 횡그루브가 복합적으로 형성되는 타이어에 있어서, 상기 숄더부에 형성되는 횡그루브의 내부에 보조블럭을 형성시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, the present invention is characterized in that in the tire in which the longitudinal groove and the horizontal groove are formed in combination, an auxiliary block is formed inside the horizontal groove formed in the shoulder portion.

이하에서는 첨부 도면을 참조하여 본 발명의 바람직한 실시 예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명에 따른 트래드부를 발췌 도시한 평면도이고, 도 2 는 본 발명의 보조블럭이 설치된 횡그루브를 발췌 도시한 단면도이며, 도 3 의 (A)(B)(C)는 본 발명의 요부인 보조블럭을 발췌 도시한 사시도이다.Figure 1 is a plan view showing an extract of the tread portion according to the present invention, Figure 2 is a cross-sectional view showing a lateral groove is installed, the auxiliary block of the present invention, Figure 3 (A) (B) (C) of the present invention It is a perspective view which shows the auxiliary block which is a main part.

도 1 내지 도 3 에 도시된 바와 같이, 본 발명은 트래드부(1)에 종그루브(2)와 횡그루브(3)가 복합적으로 형성되는 타이어에 있어서, 상기 횡그루브(3)의 내부에 보조블럭(4)을 형성시켜 구성되는 것으로, 상기 보조블럭(4)은 횡그루브(3)를통한 배수성을 고려하여 횡그루브(3)의 양측벽면(31, 32)과 이격되도록 형성되는 것이다.As shown in Figures 1 to 3, the present invention, in the tire in which the longitudinal groove (2) and the horizontal groove (3) is formed in combination in the tread portion (1), the auxiliary groove inside the horizontal groove (3) The auxiliary block 4 is formed so as to be spaced apart from both sidewalls 31 and 32 of the horizontal groove 3 in consideration of the drainage through the horizontal groove 3.

또한 상기 보조블럭(4)은 높이는 블록의 높이와 동일하게 형성시키며, 보조블럭(4)의 형상은 도 3 에 도시되는 바와 같이, 원뿔, 삼각뿔, 사각뿔 등의 형상으로 형성시켜 보조블럭(4)의 외주면(40)이 경사지게 형성된다.In addition, the auxiliary block 4 is formed to have the same height as the height of the block, the shape of the auxiliary block 4, as shown in Figure 3, formed in the shape of a cone, a triangular pyramid, a square pyramid, such as the auxiliary block (4) The outer circumferential surface 40 is formed to be inclined.

이와 같이 구성되는 본 발명은 폭이 큰 림에 장착되는 경우 또는 고하중이 전가되거나 심한 코너링 동작시 원심력에 의한 횡그루브(3)의 변형을 최소화시킴은 물론 횡그루브(3)가 노면에 접촉되는 과정에서 보조블럭(4)이 징검다리의 역할을 하여 임펙트노이즈를 억제시키게 되는 것이다.The present invention configured as described above minimizes the deformation of the lateral grooves 3 due to the centrifugal force when mounted on a wide rim or when a heavy load is transferred or a severe cornering operation, and the lateral grooves 3 are in contact with the road surface. In the process, the auxiliary block 4 serves as a stepping stone to suppress the impact noise.

본 발명은 전술한 실시 예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

이상에서와 같이 본 발명에 따르면 폭이 큰 림에 장착되는 경우 또는 고하중이 전가되거나 심한 코너링 동작시 원심력에 의한 횡그루브의 변형을 최소화시켜 이상 마모를 방지하고, 횡그루브에서 발생하는 임펙트노이즈를 억제시킬 수 있는 효과가 있는 것이다.As described above, according to the present invention, when it is mounted on a large rim or when a high load is transferred or severe cornering operation, the deformation of the lateral grooves is minimized by the centrifugal force to prevent abnormal wear, and the impact noise generated in the lateral grooves is prevented. There is an effect that can be suppressed.
