The invention discloses an automobile energy-saving and noise-reducing air inlet system assembly. The assembly is characterized in that a plurality of silencing pipes are arranged in a first noise-reducing area, a resonant cavity is formed in a second noise-reducing area, silencing cotton is arranged between an air inlet pipe and an inner pipe, a plurality of damping rods are evenly arranged between a first mounting ring and a second mounting ring, each damping rod comprises a sleeve, a damping spring and an inner rod, after airflow is absorbed into a noise reduction box through the air inlet pipe, the airflow passes through the resonant cavity and the silencing pipe in the noise reduction box, so that the air is not prone to resonance, a large amount of noise is thereby reduced, meanwhile, when the airflow absorbed by the air inlet pipe vibrates in the inner pipe, force generated during vibration is buffered through damping springs in the damping rods, the noise generated by airflow vibration is further absorbed through the silencing cotton, and therefore, the noise reduction effect of the automobile energy-saving and noise-reduction air inlet system assembly is improved.
本发明公开了一种汽车节能降噪进气系统总成,所述第一降噪区内设置有多个消音管,所述第二降噪管内设置有所述谐振腔,所述进气管和所述内管之间设置有所述消音棉,所述第一安装环和所述第二安装环之间设置均匀有多根所述减震杆,每根所述多根减震杆均包括套管、减震弹簧和内杆,通过所述进气管将气流吸收在所述降噪箱内后,通过所述降噪箱内的所述谐振腔和所述消音管,使得气体不易共振,从而减少大量噪音,同时通过所述进气管吸收的气流在所述内管中振动时,通过所述减震杆内的所述减震弹簧,缓冲掉振动时产生的力,并且通过所述消音棉进一步吸收气流振动产生的噪音,从而提高所述汽车节能降噪进气系统总成的降噪效果。
