Description

소음 저감용 타이어 트레드의 홈 패턴구조{Groove structure of tire for noise reduction}Groove structure of tire for noise reduction

본 발명은 타이어 주행시 타이어에서 발생하는 소음을 저감시키는 타이어 트레드의 홈 패턴구조에 관한 것으로, 더욱 상세하게는 타이어 길이방향(Longitudinal) 홈에서 발생하는 파이프 공명음(Pipe resonance) 소음을 저감하는 소음 저감용 타이어 트레드의 홈 패턴구조에 관한 것이다.The present invention relates to a groove pattern structure of a tire tread for reducing noise generated from a tire while driving a tire. More particularly, the present invention relates to a noise reduction for reducing pipe resonance noise generated in a tire longitudinal groove. It relates to a groove pattern structure of a tire tread.

타이어의 소음은 타이어 패턴과 도로면의 마찰로 인해 발생하며, 도로면의 상태에 따라 소음레벨이 달라지는데, 타이어의 주 소음원인 중 중요한 인자는 타이어의 길이방향의 홈(Groove)에서 발생하는 소음이며, 이는 파이프 공명음(Pipe resonance)으로 정의하고 있다.The noise of the tire is caused by the tire pattern and the friction of the road surface, and the noise level varies according to the condition of the road surface. An important factor among the main noise sources of the tire is the noise generated from the groove in the longitudinal direction of the tire. This is defined as pipe resonance.

타이어에서 발생하는 파이프 공명음의 주파수는 f = c/2L(L은 타이어가 지면과 접지하였을 때 접지장의 길이, c는 음속으로 일반적으로 340m/second)로 나타나고, 타이어 패턴의 접지길이에 따라 이 주파수는 이동하기 때문에 고성능 타이어처럼 접지장의 길이가 짧은 타이어는 파이프 공명음 주파수가 1kHz 대역 이상으로 나타나고 있다.The frequency of the pipe resonance sound from a tire is expressed as f = c / 2L (L is the length of the ground when the tire is grounded to the ground, c is the sound velocity, typically 340 m / second). Because the frequency shifts, tires with short ground lengths, such as high-performance tires, exhibit a pipe resonance frequency above 1 kHz.

타이어의 통상적인 접지선단은 스퀘어 형태(Square type)와 라운드 형태(Round type)로 구분할 수 있는바, 여기서 전자인 타이어 접지선단이 스퀘어 형태는 타이어 진행방향의 홈 길이가 동일하기 때문에 단일 파이프 공명음이 발생하지만, 후자인 타이어 접지선단이 라운드 형태(도 3 타이어 접지장 참고)의 경우 각 홈들의 접지장 길이가 다르기 때문에 여러 개의 파이프 공명음이 발생하게 된다.Typical grounding ends of tires can be divided into square and round types, where the former tire grounding ends are square pipes with the same groove length in the tire traveling direction. In this case, the latter tire ground end is round (see FIG. 3 tire grounding field), so that the length of the grounding ground of each groove is different, so that several pipe resonance sounds occur.

이에 본 발명은 상기와 같이 타이어 접지현상이 라운드 형태의 타이어 트레드 패턴에서 각 홈들에서 발생하는 여러 개의 파이프 공명음을 저감시킬 수 있는 소음 저감용 타이어 트레드의 홈 패턴구조를 제공함에 그 목적이 있다.Accordingly, an object of the present invention is to provide a groove pattern structure of a tire tread for noise reduction, which can reduce a number of pipe resonance sounds generated in respective grooves in a tire tread pattern having a round tire shape as described above.

상기와 같은 목적을 달성하기 위한 본 발명은 타이어의 진행방향을 따라 여러 개 형성된 주홈들 사이에 일정간격으로 캐비티홈이 연결되어 이루어진 타이어 트레드의 홈 패턴구조에 있어서, 상기 각각의 캐비티홈과 주홈들이 연결되는 부분에는 넥크홈들로 서로 연결되는 구조를 갖는다.The present invention for achieving the above object in the groove pattern structure of the tire tread formed by connecting the cavity grooves at a predetermined interval between the plurality of main grooves formed along the traveling direction of the tire, the respective cavity grooves and the main grooves The part to be connected has a structure in which the neck grooves are connected to each other.

상기와 같은 본 발명에 따른 소음 저감용 타이어 트레드의 홈 패턴구조는 타이어 주행시 넥크홈들에 의하여 길이방향 홈에서 발생하는 타이어의 파이프 공명음을 저감시킬 수 있는 효과를 지닌다.The groove pattern structure of the noise reduction tire tread according to the present invention has the effect of reducing the pipe resonance sound of the tire generated in the longitudinal groove by the neck grooves when the tire running.
