Field of the Invention [0002] The present invention relates to a tire for use in an automobile having improved eye travel performance, and more particularly to a tire in which a plurality of blocks are provided on a tread and a plurality of transverse cuffs are formed on each block.

본 발명은 눈길 주행 성능을 향상시킨 자동차용 타이어에 관한 것으로, 특히, 트레드에 다수의 블록이 설치되고 각각의 블록에 횡방향의 커프가 다수개 형성된 타이어로서, 각각의 블록에 설치된 커프와 커프 사이의 분할부를 경사면부로 형성시켜서 된 타이어가 일본 공개특허공고 제JP2005-001621호로 개시된 바 있다.        More particularly, the present invention relates to a tire having a plurality of blocks provided on a tread and having a plurality of transverse cuffs formed on each of the blocks, wherein the cuffs provided between the cuffs and the cuffs And a tread formed by forming the divided portion of the tread portion into an inclined surface portion is disclosed in JP2005-001621A.

일본 공개특허공고 제JP2005-001621호의 타이어는 커프와 커프 사이의 분할부 접지면이 전체적으로 경사진 경사면으로 되어 있어 거칠기가 커져서 높은 에지효과를 내는 장점은 있으나, 접지 면적이 크게 감소되어 견인력과 제동력이 부족한 결점이 있으며 이상 마모의 염려가 큰 결점이 있다. Japanese Unexamined Patent Application Publication No. 2005-001621 discloses a tire in which the ground surface of the divided portion between the cuff and the cuff is formed as an inclined surface that is inclined as a whole to increase the roughness and thereby provide a high edge effect. However, the ground area is greatly reduced and the tractive force and braking force There are insufficient defects and worry about abnormal wear is a big drawback.

이에 본 발명은 트레드에 다수의 블록이 설치되고 각각의 블록에 횡방향의 커프가 다수개 형성된 타이어로서, 각각의 블록에 설치된 커프와 커프 사이의 분할부를 경사면부로 형성시켜 거칠기를 증가시킴으로써 높은 에지효과를 내게 하면서도 접지 면적의 감소량을 적게하여 견인력과 제동력이 부족하게되는 결점을 해소한 타이어를 제공하여야 한다는 과제를 해결하고자 한다.  Accordingly, the present invention provides a tire having a plurality of blocks mounted on a tread and having a plurality of transverse cuffs formed on each of the blocks, wherein the divided portion between the cuff and the cuff provided on each block is formed as a slope portion, And a reduction in the ground surface area while reducing the drawback and braking force of the tire. SUMMARY OF THE INVENTION

위와 같은 과제를 해결하기 위하여 본 발명은, 트레드에 다수의 블록이 설치되고 각각의 블록에 횡방향의 커프가 다수개 형성된 것에 있어서, 각각의 블록에 설치된 커프와 커프 사이의 분할부를 평면부와 경사면부로 형성시키고, 경사면부를 트레일링부에 형성시켜서 된 것임을 특징으로 하는 타이어를 제공한다.In order to solve the above problems, the present invention is characterized in that a plurality of blocks are provided on a tread and a plurality of transverse cuffs are formed on each block, wherein the divided portion between the cuff and the cuff, And the inclined surface portion is formed in the trailing portion.

위와 같이 구성된 본 발명은 리딩에지의 날카로운 경사부가 에징효과를 발휘하여 눈길 주행 성능을 향상시키는 효과가 있으면서도, 접지 면적의 감소량을 적게하여 견인력과 제동력이 부족하게되는 결점을 해소한 타이어를 제공하게 되는 효과 가 있다.According to the present invention having the above-described structure, a sharp inclined portion of the leading edge exhibits an effect of edge enhancement, thereby improving the running performance of the snowy road while reducing the amount of reduction of the ground surface area, thereby eliminating the drawbacks of insufficient traction and braking force. It is effective.

트레드(1)와 트레드 양측의 사이드월 및 사이드월 양단의 비드부로 구성되며 트레드(1)에 다수의 블록(2)이 설치되고, 블록(2)에 횡방향으로 다수의 커프(3)가 형성되어 블록(2)이 커프(3)로 인하여 다수개의 분할부(4)로 구성되는 자동차용 타이어에 있어서, 본 발명은 분할부(4)의 일부를 평면부(41)로 형성시키며, 다른 일부를 경사면부(42)로 형성시켜서 되는 눈길 주행 성능을 향상시킨 자동차용 타이어를 제공한다. 본 발명은 이에서 나아가, 경사면부(42)가 지면에 늦게 닿는 부위인 트레일링부에 형성된 것을 특징으로 하는 타이어를 제공한다.A plurality of blocks 2 are provided on the tread 1 and a plurality of cuffs 3 are formed on the block 2 in a transverse direction, which are constituted by the tread 1 and the sidewalls on both sides of the tread and both ends of the sidewall, (2) is constituted by a plurality of divided portions (4) due to the cuff (3), the present invention is characterized in that a part of the divided portion (4) is formed as a flat surface portion (41) And a slant surface portion (42) formed on the slant surface (42). The present invention further provides a tire characterized in that it is formed on a trailing portion which is a portion where the slope portion (42) touches the ground later.

또한, 본 발명은 평면부(41)의 폭(w2)이 분할부(4) 폭(w)의 1/2보다 큰 타이어를 제공한다. Further, the present invention provides a tire in which the width w2 of the flat surface portion 41 is larger than 1/2 of the width w of the divided portion 4.

또한 본 발명은 경사면부(42)의 시작점(421)에 단차(422)를 형성시키며, 단차(422)의 높이를 0.3~0.5mm로 하여서 되는 타이어를 제공한다. The present invention also provides a tire in which a step 422 is formed at the starting point 421 of the inclined face portion 42 and the height of the step 422 is 0.3 to 0.5 mm.

경사면부(42)의 경사단부(423)의 경사높이(H)는 0.5~0.8mm인 것이 바람직하다. The inclined height H of the inclined end portion 423 of the inclined surface portion 42 is preferably 0.5 to 0.8 mm.
