Novel automotive silencing equipment

Abstract

The invention belongs to the technical field of silencer manufacturing and particularly relates to novel automotive silencing equipment. The novel automotive silencing equipment comprises a shell, a front end cover, a rear end cover, an air inlet pipe, a buffer pipe, an air outlet pipe, a first partition plate, a second partition plate, a third partition plate, a partition plate support, a first cavity, a second cavity, a third cavity, a fourth cavity, silencing cotton and glass fiber cotton. The front end cover and the rear end cover are arranged at the two ends of the shell respectively. The first partition plate, the second partition plate and the third partition plate are sequentially arranged inside the shell. The second partition plate is connected with the third partition plate through the partition plate support. The shell is divided into the first cavity, the second cavity, the third cavity and the fourth cavity through the first partition plate, the second partition plate and the third partition plate. The novel automotive silencing equipment is good in silencing effect and high in silencing speed.

Description

technical field [0001] The invention belongs to the technical field of muffler manufacture, and in particular relates to a novel vehicle muffler equipment. Background technique [0002] With the advancement of science and technology and the improvement of automobile technology level, the requirements for various indicators of automobiles in the national standard have been improved, and the noise reduction equipment for vehicles is an important equipment in the field of automobile engineering technology, and the requirements for automobile noise emission standards in the national standard are also Higher and higher. The vehicle noise reduction equipment in the prior art includes a housing, an air inlet pipe, an air outlet pipe, a first partition and a second partition, and the first partition and the second partition divide the housing into a first chamber, a second chamber, and a second chamber. chamber and the third chamber, the air inlet pipe passes through the housing, t...

AI Technical Summary

Problems solved by technology

[0003] 1. The resistive sound-absorbing layer on the air inlet pipe and the air outlet pipe eliminates high-frequency noise, but has a poor effect on low-frequency noise, and the scope of application is narrow

[0004] 2. The noise can only enter the third chamber through the resistive sound-absorbing layer on the inlet pipe, and then enter the outlet pipe in the second chamber through the round hole on the second partition, and then use the The resistive sound-absorbing layer is discharged after noise reduction. The whole noise reduction process has a single noise reduction method, and the noise reduction speed is slow.
