The protective structure of the exhaust branch pipe below the automobile chassis comprises a mounting pipe and a flow dividing box, the flow dividing box is located at the position, close to the top, of the right side of the mounting pipe, a connecting pipe is fixedly connected to the position, close to the center, of the left side of the mounting pipe, and a protective pipe is fixedly connected to the left end of the connecting pipe; the protective pipe and an inner cavity of the connecting pipe are communicated with each other, first bearings are fixedly connected to the positions, close to the top end and the bottom end, of the left side and the right side of the inner cavity of the protective pipe correspondingly, noise reduction is conducted on sound waves through the noise reduction pipe and the noise reduction disc, and the sound waves enter an inner cavity of the noise reduction cover through a plurality of through holes formed in the noise reduction pipe; after the noise reduction cover collides back and forth in the inner cavity of the noise reduction cover, the sound volume is reduced and then output, the noise volume of wheels during high-speed driving is greatly reduced, meanwhile, the best smoothness of an exhaust pipeline can be guaranteed during low-speed driving, the performance power of a vehicle can be better improved, and energy consumption can be better saved.
本发明公开了汽车底盘下方的排气支管的防护结构,包括安装管和分流箱,所述分流箱位于安装管的右侧靠近顶部处,所述安装管的左侧靠近中心处固定连接有连接管,所述连接管的左端固定连接有防护管,且所述防护管与连接管的内腔之间为相互贯通设置,所述防护管的内腔左右两侧靠近顶端与底端处均固定连接有第一轴承,通过减噪管和减噪盘对声浪进行降噪,声浪通过减噪管上设置的若干个通孔进入到减噪罩的内腔,在减噪罩的内腔来回碰撞后减低了声音量再进行输出,大大减低了车轮在高速行驶时的噪音量,同时在低速行驶时能够保障排气管道的最佳通畅度,能够更好的提高车辆的性能动力和节约能耗。
