Abstract

PURPOSE: A pneumatic tire for preventing noise and vibration is provided to offset the stiffness in the overlap of parts, and to restrict noise and vibration during traveling by modifying the shape of a bead filler. CONSTITUTION: A pneumatic tire is composed of a tread part, a side wall and a bead part. The bead part consists of a bead core(30) and a bead filler(4) stacked in the upper part of the bead core. Plural grooves(40) are formed radially and irregularly at the side of the bead filler. Various triangular, rectangular, semicircular and trapezoid grooves are formed in the circumference of the tire. The irregular stiffness of the bead filler is formed circumferentially with forming grooves in the bead filler. Abnormal noise is reduced, and noise is restricted with offsetting the stiffness in the overlap part of parts by forming the irregular sectional area of the bead filler circumferentially.

소음과 진동성능을 향상시킨 공기입 타이어 {Pneumatic tire improved noise and vibration}Pneumatic tire improved noise and vibration

본 발명은 소음과 진동성능을 향상시킨 공기입 타이어에 관한 것으로, 더욱 상세하게는 비드필러의 형상을 개선하여 각 부품의 오버랩부위의 강성증대로 발생되는 소음과 진동을 억제시킬 수 있게 하는 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire having improved noise and vibration performance, and more particularly, to improve the shape of the bead filler, and to suppress the noise and vibration caused by the increase in the rigidity of the overlap portion of each component. It's about tires.

일반적으로 공기입 타이어는 사이드월, 카카스, 트래드 벨트 등 다수의 부품이 조합되어 구성되는 것으로, 각각의 부품은 원통형의 성형드럼에 권회되고, 각 부품의 단부는 서로 겹쳐지게 결합된다.In general, the pneumatic tire is composed of a combination of a number of parts, such as sidewalls, carcass, tread belt, each part is wound on a cylindrical forming drum, the end of each part is coupled to overlap each other.

이러한 각 부품의 겹쳐진 부위(이하 오버랩부위라 칭함)는 타 부위에 비하여 강한 강성을 가지기 마련이고, 이는 타이어의 주행시 심한 소음과 진동을 유발시키게 된다.The overlapped portions of each of these parts (hereinafter referred to as overlapped portions) have stronger rigidity than other portions, which causes severe noise and vibration when the tire is running.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명은 비드필러의 단면적을 원주방향으로 불균일하게 형성시켜 각 부품의 오버랩부위의 강성을 상쇄시킬 수 있게 하여 소음과 진동성능을 향상시킬 수 있게 하는 공기입 타이어를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, the present invention is to form a non-uniform cross-sectional area of the bead filler in the circumferential direction to cancel the stiffness of the overlapping portion of each component to improve the noise and vibration performance The object is to provide a pneumatic tire that makes it possible.

본 발명은 상기와 같은 목적을 달성하기 위하여 다음과 같이 구성된다. 즉, 본 발명은 트래드부와 사이드월 및 비드부로 구성되고, 상기 비드부가 비드코아와비드코아의 상부에 적층되는 비드필러로 구성되는 것에 있어서, 상기 비드필러의 일측면에 다수의 홈을 불규칙하게 형성시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, the present invention comprises a tread portion, a side wall and a bead portion, wherein the bead portion is composed of a bead filler stacked on top of the bead core and the bead core, irregularly a plurality of grooves on one side of the bead filler It is characterized by being formed.

도 1 내지 도 3 에 도시되는 바와 같이, 본 발명은 트래드부(1)와 사이드월(2) 및 비드부(3)로 구성되고, 상기 비드부(3)가 비드코아(30)와 비드코아(30)의 상부에 적층되는 비드필러(4)로 구성되는 것에 있어서, 상기 비드필러(4)의 일측면에 다수의 홈(40)을 레디알 방향으로 불규칙하게 형성시켜 구성되는 것으로, 상기 홈의 형상은 삼각형, 사각형 반원형, 사다리꼴 등의 다양한 형상으로 형성시킬 수 있으며, 형성되는 홈(40)의 숫자는 타이어 원주방향으로 4∼12개의 범위 내에서 형성시켜 구성된다.As shown in Figs. 1 to 3, the present invention comprises a tread portion 1, a sidewall 2 and a bead portion 3, wherein the bead portion 3 is a bead core 30 and a bead core. In the bead filler 4 stacked on top of the 30, a plurality of grooves 40 are formed irregularly in the radial direction on one side of the bead filler 4, The shape can be formed into various shapes such as triangular, rectangular semicircular, trapezoidal, and the like, and the number of the grooves 40 to be formed is formed by forming within the range of 4 to 12 in the tire circumferential direction.

이와 같이 구성되는 본 발명은 비드필러(4)에 형성되는 홈(40)에 의해 비드필러(4)의 강성이 원주방향으로 분균일하게 됨으로써, 각 부품의 오버랩부위의 큰 강성을 상쇄시켜 이상소음 발생과 진동을 억제시키게 되는 것이다.The present invention configured as described above makes the stiffness of the bead filler 4 uneven in the circumferential direction by the grooves 40 formed in the bead filler 4, thereby canceling out the large stiffness of the overlapped portions of the respective parts, thereby making abnormal noise. It is to suppress the generation and vibration.

본 발명은 전술한 실시 예에 한정되지 않고 본 발명의 기술사상이 허용하는범위 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 비드필러의 단면적이 원주방향으로 불균일하게 형성됨으로써, 각 부품의 오버랩부위의 강성을 상쇄시켜 소음과 진동성능을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, since the cross-sectional area of the bead filler is not uniformly formed in the circumferential direction, there is an effect that the noise and vibration performance can be improved by canceling the rigidity of the overlapped portion of each component.
