Abstract

PURPOSE: A tread block structure for a heavy duty tire is provided to maximally reduce driving stability loss and abrasion loss which is generated at an end of a block when a vehicle is driven on a dry road and to improve traction efficiency and grip efficiency on tread surfaces. CONSTITUTION: A tread block structure for a heavy duty tire comprises grooves and rectangular shaped block bodies(2) which directly touch a road. The block bodies are connected with the bottom of a leading end portion(4) which is the first to come in contact with the road when a tire moves by being inclined from 10 degrees to 20 degrees based on a connection point of the tread and a predetermined virtual line. The bottom of a trailing portion(7) which is the final contact point with the road is connected with the connection portion of the tread by being inclined and rounded from 20 degrees to 40 degrees based on the predetermined vertical line.

중하중용 타이어 트레드의 블럭구조{Block structure of TBR tire tread}Block structure of TBR tire tread

본 발명은 중하중용 타이어의 트레드 디자인 중 블럭구조에 관한 것으로, 더욱 상세하게는 노면과 접촉하는 블럭의 면적을 최대로 하여 블럭 변형을 최소화하고 구동시 블럭 끝단에서 발생하는 마모량을 저감하여 충분한 블럭 강성을 유지할 수 있는 중하중용 타이어 트레드의 블럭구조에 관한 것이다.The present invention relates to a block structure of the tread design of the heavy-duty tire, and more particularly, to maximize the area of the block in contact with the road surface to minimize block deformation and to reduce the amount of wear generated at the end of the block during driving, sufficient block rigidity It relates to a block structure of a heavy-duty tire tread that can maintain a.

타이어에서 노면과 직접 접촉하는 부분을 트레드(Tread)라 칭하며, 이 트레드에는 블럭들과 그루브(Groove) 등이 일정한 패턴으로 형성되어 트레드 디자인을 갖도록 되어 있다.The part of the tire that is in direct contact with the road surface is called a tread, and blocks and grooves are formed in a predetermined pattern to have a tread design.

이러한 트레드 디자인은 크게 리브(Rib)형 디자인 패턴과 러그(Lug)형 디자인 패턴 및 블럭(Block)형 디자인 패턴으로 구별되는데, 본 발명은 이중 트레드의 블럭구조에 대한 기술이다.Such a tread design is largely divided into a rib type pattern, a lug type design pattern, and a block type design pattern. The present invention is a technique for a double tread block structure.

이에 본 발명은 중하중용 타이어의 트레드에 배열되는 블럭 디자인의 구조로서 오프로드(off road) 주행에서 견인성능과 트레드 폭 방향의 그립(Grip) 성능을 향상시키고 건조노면에서의 조종 안정성 및 구동시 블럭 끝단에서 발생하는 마모량을 최대로 저감할 수 있는 중하중용 타이어 트레드의 블럭구조를 제공함에 그 목적이 있다.Accordingly, the present invention is a block design structure that is arranged on the tread of the heavy-duty tire to improve the traction performance and grip performance in the tread width direction in the off-road driving, the steering stability on the dry road surface and the block when driving An object of the present invention is to provide a block structure of a heavy-duty tire tread capable of maximally reducing the amount of wear occurring at the end.

상기와 같은 목적을 달성하기 위한 본 발명은 노면과 접하는 연속 형성된 블럭 몸체들과 그루브들이 형성된 트레드에서 직접 노면에 접촉하는 중하중용 타이어 트레드의 블럭구조에 있어서, 상기 블럭 몸체는 타이어 구동시 노면과 접하는 시작단인 리딩부의 바닥이 트레드의 연결부분과 가장 수직선을 기준으로 10° ~ 20° 각도로 경사진 경사면으로 연결되고, 노면과 직접 접하는 블럭 몸체의 끝단인 트레일링부의 바닥이 트레드의 연결부분과 가상 수직선을 기준으로 20° ~ 40°각도로 라운드진 경사면으로 연결되어 설계된 구조를 특징으로 한다.In order to achieve the above object, the present invention provides a block structure of a heavy-load tire tread that directly contacts a road surface in a tread formed with continuous block bodies and grooves formed in contact with a road surface, wherein the block body is in contact with a road surface when a tire is driven. The bottom of the leading part, which is the starting end, is connected to the inclined surface at an angle of 10 ° to 20 ° with respect to the connection part of the tread, and the bottom of the trailing part, which is the end of the block body directly contacting the road surface, It features a structure designed to be connected by rounded slopes at an angle of 20 ° to 40 ° with respect to an imaginary vertical line.

이러한 본 발명에 따른 중하중용 타이어 트레드의 블럭구조는 타이어 구동시 리딩구역의 블럭 형상이 노면과 10° ~ 20°을 이루며 타이어가 노면에 접촉되는 순간 최대한 면적을 크게하여 블럭형상을 최소화하고, 트레일링 구역의 블럭형상을 노면과 20° ~ 40°로 각을 이루며 구동시 습립을 최소화하면서 라운드진 경사면에 의해 코너링시 충분한 블럭강도를 유지하도록 되어 있다.The block structure of the heavy-duty tire tread according to the present invention forms a block shape of the leading zone when the tire is driven to 10 ° to 20 ° and minimizes the block shape by increasing the maximum area as soon as the tire is in contact with the road surface. The block shape of the ring zone is angled from 20 ° to 40 ° with the road surface, and it is designed to maintain sufficient block strength when cornering by the rounded slope while minimizing erosion during driving.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도 1과 도 2에 도시된 바와 같이 노면(1)과 직접 접하는 타이어 트레드(5)에 형성된 블럭구조로서, 노면(1)과 직접 접하는 연속 형성된 직육면체 형상의 블럭몸체(2)들과 그루브(3)들이 형성된 중하중용 타이어 트레드의 블럭구조에 있어서, 상기 블럭몸체(2)는 타이어 구동시 노면(1)과 접하는 시작단인 리딩부(4)의 바닥(4a)이 트레드(5)의 연결부분(5a)과 가상 수직선(V)을 기준으로 10° ~ 20°각도로 경사진 경사면(6)으로 연결되고, 노면(1)과 직접 접하는 블럭몸체(2)의 끝단인 트레일링부(7)의 바닥(4a)이 트레드(5)의 연결부분(5b)과 가상 수직선(V)을 기준으로 20° ~ 40°각도로 라운드진 경사면(8)으로 연결되어 설계된 구조로 되어 있다.The present invention is a block structure formed on the tire tread (5) in direct contact with the road surface (1) as shown in Figures 1 and 2, and the block body (2) of continuous rectangular parallelepiped shape directly contacting the road surface (1) and In the block structure of a heavy-duty tire tread having grooves 3 formed therein, the block body 2 has a bottom 4a of the leading portion 4 which is a starting end contacting the road surface 1 when the tire is driven. The trailing portion that is connected to the inclined surface 6 inclined at an angle of 10 ° to 20 ° based on the connecting portion 5a and the virtual vertical line V of the block body 2 directly contacting the road surface 1 ( The bottom 4a of 7) is designed to be connected to the inclined surface 8 rounded at an angle of 20 ° to 40 ° based on the connecting portion 5b of the tread 5 and the virtual vertical line V.

통상적으로 타이어 주행시 트레드(5)의 블럭몸체(2)와 노면(1)의 접촉부위에서 많은 슬립이 발생하게 된다.Typically, a lot of slip occurs at the contact portion of the block body 2 and the road surface 1 of the tread 5 when the tire is running.

특히, 상기 블럭몸체(2)의 리딩부(4)에는 순간적인 변형에 의해 고무압축이 발생하게 되고, 트레일링부(7)의 경우 블럭몸체(2)의 끝단의 타이어 변형에 의한 슬립과 롤링(Rolling)으로 슬립이 더 가해져서 많은 마모가 발생하는데, 이는 타이어 매회전시 블럭패턴의 힐(Heel)과 토우(Toe) 양을 증가시킨다.Particularly, rubber compression is generated in the leading part 4 of the block body 2 by instantaneous deformation, and in the case of the trailing part 7, slip and rolling due to tire deformation of the end of the block body 2 are performed. Slips are added to the rolls, causing a lot of wear, which increases the amount of heel and toe in the block pattern at every tire turn.

그러나 본 발명에 따른 트레드의 블럭구조는 상기 블럭몸체(2)의 리딩부(4)가 도 3과 도 4에 도시된 바와 같이 노면(1)과 10° ~ 20°각을 이루고 있기 때문에 이 리딩부(4)의 바닥(4a)이 노면(1)에 접촉되는 순간, 접촉면적을 최대로 크게하여 블럭몸체(2)의 변형을 최소화할 수 있다.However, the block structure of the tread according to the present invention is because the leading part 4 of the block body 2 forms an angle of 10 ° to 20 ° with the road surface 1 as shown in FIGS. 3 and 4. When the bottom 4a of the portion 4 is in contact with the road surface 1, the contact area can be maximized to minimize the deformation of the block body 2.

또한, 상기 블럭몸체(2)의 트리일링부(7)가 노면(1)과 20° ~ 40°각도를 이루고 있기 때문에 타이어 구동시 상기 트레일링부(7)의 바닥(4a)의 슬립을 최소화할 수 있도록 라운드진 경사면(8)을 갖게 되어 구동시 슬립의 최소화와 코너링시 충분한 블럭 강성을 유지할 수 있도록 되어 있다.In addition, since the trimming part 7 of the block body 2 forms an angle of 20 ° to 40 ° with the road surface 1, the slip of the bottom 4a of the trailing part 7 is minimized when the tire is driven. It has a rounded inclined surface 8 so as to minimize slip during driving and maintain sufficient block stiffness during cornering.
