Abstract

본 발명은 자동차의 흡기다기관용 가변형 소음기에 관한 것으로, 특히 자동차의 엔진에 장착되는 흡기다기관으로부터 발생되는 엔진의 폭발음에 대한 주파수를 가변시키는 1/4 파장관(Quarter Wavelength Tube)을 흡기관로에 연결하며, 엔진으로부터 발생되는 폭발음을 최소화히키기 위한 가변형 소음기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable silencer for an intake manifold of an automobile, and in particular, connects a quarter wave tube (Quarter Wavelength Tube) for varying the frequency of the explosion sound of the engine generated from the intake manifold mounted on the engine of the automobile. And, it relates to a variable silencer for minimizing the explosion sound generated from the engine.

즉, 통상의 고정형 사이드브랜치공명관(10)으로 흡기관로(2)에 형성된 고정공명관(30)과, 상기 고정공명관(30)의 외주에 삽입되게 구성되며 관의 길이(L)를 수직으로 조절할 수 있는 파장조절관(40)과, 상기 파장조절관(40)의 외주에 형성되어 수직운동으로 파장조절관(40)을 조절할 수 있는 랙기어(45)와, 상기 랙기어(45)와 맞물려 회전운동을 하는 피니언기어(50)와, 상기 피니언기어(50)에 정과 역의 회전력을 주는 모터(60)로 구성되고, 도한 상기 고정공명판(30)과 상기 파장 조절관(40)의 수직운동에 대한 마찰을 흡수하는 링(35)으로 구성한 것이 특징이다.That is, a fixed resonance tube 30 formed in the intake pipe passage 2 as a conventional fixed side branch resonance tube 10, and is configured to be inserted into the outer circumference of the fixed resonance tube 30 and to adjust the length (L) of the tube vertically Wavelength control tube 40 and the rack gear 45, which is formed on the outer periphery of the wavelength control tube 40 can adjust the wavelength control tube 40 in the vertical motion, and meshes with the rack gear 45 The pinion gear 50 and the motor 60 to give the pinion gear 50 a positive and reverse rotational force, and also the vertical movement of the fixed resonance plate 30 and the wavelength control tube 40 It is characterized by consisting of a ring 35 for absorbing friction against.
