Abstract

본 발명의 차량 주행중 노면접지에 의해 발생하는 타이어의 공동공명 소음을 감쇄시키기 위하여 타이어 림 저면에 헬름홀츠 공명기를 부착한 것이다.Helmholtz resonator is attached to the bottom of the tire rim in order to reduce the cavity resonance noise of the tire generated by the road grounding of the vehicle of the present invention.

Description

타이어 소음을 감소시키는 공명기형 타이어 림Resonator Tire Rim Reduces Tire Noise

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 헬름홀츠 공명기(HELMHOLTZ RESONATOR)가 형성된 타이어 림(RIM)의 단면도.1 is a cross-sectional view of a tire rim on which a HELMHOLTZ RESONATOR is formed.

제2도는 헬름홀츠 공명기 내에 스르링과 댐퍼가 부가된 타이어 림의 단면도.2 is a sectional view of a tire rim with a thring and a damper added in a Helmholtz resonator.

제3도는 헬름홀츠 공명기의 내외면에 흡음재가 부착된 타이어 림의 단면도.3 is a cross-sectional view of a tire rim having sound absorbing materials attached to inner and outer surfaces of a Helmholtz resonator.

Claims (3)

C=음속, L=관의 길이, S=관의 횡단면적, 그리고 V=용적이라 할 경우, 공명주파수(f0)가 f0=C/2 로 결정되는 헬름홀츠 공명기를 타이어 림 히부에 형성하되 상기 공명주파수(f0)는 타이어 공동공명(cavity resonance)주파수의 1차 모드범위로 결정되는 것을 특징으로 하는 헬름홀츠 공명기가 부착된 타이어 림.If C = sonic velocity, L = tube length, S = cross-sectional area of the tube, and V = volume, the resonance frequency (f 0 ) is f 0 = C / 2 Helmholtz resonator is determined to be formed on the tire rim, but the resonance frequency (f 0 ) is a tire rim with a Helmholtz resonator, characterized in that determined by the primary mode range of the cavity resonance (cavity resonance) frequency. 제1항에 있어서, 헬름홀츠 공명기 내에 스프링 및 댐퍼가 부가적으로 부착된 것을 특징으로 하는 헬름홀츠 공명기가 부착된 타이어 림.The tire rim with a Helmholtz resonator according to claim 1, wherein a spring and a damper are additionally attached to the Helmholtz resonator. 제1항에 있어서, 헬름홀츠 공명기의 내주면 및 타이어 림의 내주면 상에 흡음재가 부가적으로 부착됨을 특징으로 하는 헬름홀츠 공명기가 부착된 타이어 림.The tire rim with a Helmholtz resonator according to claim 1, wherein a sound absorbing material is additionally attached on the inner circumferential surface of the Helmholtz resonator and the inner circumferential surface of the tire rim. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
