Abstract

PURPOSE: An anti-noise and drain capacity improvement tire is provided to suppress noise and improve drain capacity in running by equally distributing ground contact pressure of tread by proper arrangement of tread blocks and grooves and doubling the number of pitch. CONSTITUTION: In an anti-noise and drain capacity improvement tire, a third groove(G3) formed in the center of tread and first and second grooves(G1,G2) formed to the right and left side of the third groove are the same in the width. First and second tread blocks(B1,B2) formed inside the first and second grooves and the fifth and sixth tread blocks(B5,B6) formed outside are the same in the width. First and second unit blocks(br1,br2) and third and fourth unit blocks(br3,br4) are the same in the area. The area of a fifth unit block(br5) is the same with the area given by adding the first unit block to the second, third, and fourth unit blocks. Some of left lateral grooves(gr1,gr2) and right lateral grooves(gr3,gr4) are crossed with moved in the circumference direction. The angle of the lateral grooves with tread circumference forms gently sloped angle on a side of the fourth unit block and forms steeply sloped angle from the outside of the second tread block to the sides of the tread. Sipes(S1¯S3, S1',S2') are formed by cutting the edges of the grooves(G,G2) side of the tread blocks at the same intervals.

Description

소음발생억제 및 배수능력향상용 타이어Noise generation and drainage capacity improvement tires

본 발명은 소음발생 억제 및 배수능력향상용 타이어에 관한 것으로서 특히 트레드 블럭 및 그루브의 적절한 배치로 트레드의 접지압을 균등하게 분포시키며 피치의 수를 배가시킴으로써 주행시 소음발생의 억제와 배수능력을 향상시킨 타이어에 관한 것이다.The present invention relates to a tire for suppressing noise generation and improving drainage capacity. In particular, a tire that has improved noise suppression and drainage ability by driving the tread blocks and grooves evenly distributes the tread ground pressure and doubles the number of pitches. It is about.

일반적으로 타이어에서의 소음 발생 형태는 크게 세가지 유형으로 나뉘어지는데 첫째, 접지압의 충격, 완화의 반복으로 인한 트레드 충격음이며 이것은 트레드 블럭의 수인 피치수와 속도에 좌우되고 둘째, 타이어가 회전하는 동안, 트레드 동공부위의 닫히고 열리는 반복작용으로 인하여 공기는 압축과 팽창을 반복하게 됨에 따라 고속상태에서 공기의 요동이 일어나게 되고 이 때문에 파이프 공명음을 동반한 소음이 발생하게 되는데 이것이 공기 유동 소음이며 셋째, 지면상에서 트레드 블럭이 미끄러짐에 따라 발생되는 것이 미끌림 소음인데 종래의 타이어는 피치를 구성하는 기본블럭 및 그루부의 부적절한 배치등으로 인해 타이어 회전시 트레드 블록이 불균일한 강성을 갖게 되어 진동이 생기고 그루브 간을 흐르는 공기의 유속이 불규칙으로 변화되며 고속주행시 하이드로 플래이닝(HYDRO PLANING)현상이 발생하여 타이어가 미끄러짐에 따라 심한 소음이 발생되었고 수막의 원활한 배출이 어려운 단점이 있었다.Generally, noise generation in tires is divided into three types: first, tread impact sound due to the impact of ground pressure and repetition of relaxation, which depends on the number of tread blocks, the number of pitches and the speed, and secondly, the tread while the tire rotates. Due to the repeated closing and opening of the pupil part, the air repeatedly compresses and expands, causing fluctuations in the air at high speed, which causes noise accompanied by pipe resonance, which is the air flow noise. Sliding tread block is caused by slipping noise. In conventional tires, the tread block has non-uniform rigidity when the tire rotates due to improper arrangement of the basic blocks and grooves constituting the pitch, causing vibration and air flowing between the grooves. Irregular flow rate Chemistry and had a high speed traveling flag dihydro-inning (HYDRO PLANING) happens to the excessive noise generated in accordance with the tire slip has been difficult to smoothly discharge the water film disadvantages.

The area of the second unit blocks br1 and br2 and the area of the third and fourth unit blocks br3 and br4 are equal, respectively, and the fifth of the fifth and sixth tread blocks B5 and B6. The area of the unit block br5 is equal to the sum of the four first to fourth unit blocks br1 to br4, and is symmetrical with the same distance in the transverse direction from the center of the tread to the side of the tread. One side grooves of the left circumferential grooves gr1 and gr2 and the right circumferential grooves gr3 and gr4 are alternately arranged in a circumferential direction by a half pitch, and the left and right lateral grooves gr1 to gr4 are disposed. ) Forms an angle of inclination with the tread circumferential direction from one side of the fourth unit block br4 to both sides of the tread and bends from the outside of the fifth unit block br5 to form a steep angle to both sides of the tread.

상기 그루브들(G1)(G2)(G3)의 폭들과 트레드블록들 (B1)(B2)(B5)(B6)의 폭들과 상기 제1,제2단위블록들(br1)(br2)의 면적들 및 상기 제3,제4단위블록들(br3)(br4)의 면적들을 각각 동일하게 하고 상기 제1내지 제4단위블록(br1)∼(br4)의 면적들의 합을 제5단위블럭(br5)의 면적과 동일하게 하여 각 트레드블럭(B1)(B2)(B5)(B6)간의 불균일한 강성을 전피치에 고르게 분산되도록 유도함으로써 균등한 접지압 분포가 되게 하여 트레드의 충격음을 저감시키고 상기 좌우측주횡그루브들(gr1)∼(gr4)중 일측주횡그루부들은 원주방향으로 반피치만을 이동시켜 서로 엇갈리게 배치함으로써 피치수를 배가시키는 역할을 하여 제3도(a)에서 참조되는 바와같이 하이드로 플래이닝(HYDRO PLANING) 현상을 줄여 미끌림 소음을 저감시키며 또한 소음 주파수를 쉽게 늘릴 수 있어 가청 주파수 상한인 1000Hz 밖으로 음역을 보낼 수 있게 됨에 따라 제3도(b)에서와 같이 현저한 소음저감을 시킬 수 있다. 여기서 상기 제3도(a)(b)의 그래프 중 X축은 피치수를 나타내고 제3도(a)의 그래프의 Y축은 하이드로 플래이닝 발생율을 나타내며 제3도(b)의 그래프의 Y축은 소음의 세기를 단위 데시벨(dB)을 사용하여 나타낸 것이다.Widths of the grooves G1, G2, and G3, widths of the tread blocks B1, B2, B5, and B6, and areas of the first and second unit blocks br1 and br2. And the areas of the third and fourth unit blocks br3 and br4 are equal to each other, and the sum of the areas of the first to fourth unit blocks br1 to br4 is equal to the fifth unit block br5. ) By equalizing the area of tread block B1 (B2) (B5) (B6) evenly distributed throughout the pitch to induce a uniform ground pressure distribution to reduce the impact sound of the tread and the left and right One side circumferential grooves of the lateral grooves gr1 to gr4 serve to double the pitch by moving only half pitches in the circumferential direction and stagger each other, thereby hydro-planing as referred to in FIG. It can reduce the slip noise by reducing the HYDRO PLANING phenomena and also increase the noise frequency easily. The ability to send sound ranges outside of 1000 Hz can result in significant noise reduction as in FIG. 3 (b). In the graphs of FIGS. 3A and 3B, the X axis represents the pitch number, the Y axis of the graph of FIG. 3A represents the hydroplaning rate, and the Y axis of the graph of FIG.

다음으로 좌우측 주횡그루브(gr1)∼(gr4)가 트레드 원주방향과 이루는 각을 변화시킴으로써 상기 주횡 그루브(grl)∼(gr4)내에 유입된 유체를 트레드 중앙부로부터 숄더쪽으로 신속하게 배출할 수 있으며 상기 트레드블록들(B1)(B2)(B5)(B6)의 주연부에 상기 사이프들(S1)∼(S3), (S1')∼(S2')을 형성하여 노면과 트레드 접지부분사이에서 톱니효과를 발휘하도록 함으로써 하이트로 플래이닝 현상을 감소시켜 미끌림 소음을 줄일 수있고 눈길 주행시 스노우 트랙션(snow traction) 성능을 극대화시키는 효과도 있다.Next, by changing the angle between the left and right main transverse grooves gr1 to gr4 with the tread circumferential direction, the fluid introduced into the main transverse grooves grl to gr4 can be quickly discharged from the center of the tread to the shoulder and the tread The sipes S1 to S3, S1 'to S2' are formed at the periphery of the blocks B1, B2, B5 and B6, so that a saw tooth effect is formed between the road surface and the tread ground portion. By doing so, you can reduce the amount of slipping by hitting the flying phenomenon with height and maximize the snow traction performance when driving on snow roads.
