A self-cleaning air suspension intake and exhaust system muffler

Abstract

The invention relates to a muffler for a self-cleaning air suspension air intake and exhaust system, which comprises a muffler main body support structure, an inner bracket, an outer shell and a sealing ring; the outer shell is fixed above the muffler main body support structure, and the inner bracket is arranged on the outer shell and the muffler In the cavity composed of the main support structure; the ordinary noise-absorbing sponge, high-density sponge and one-way valve are set in the inner bracket, the filter is set above the inner bracket, the inner bracket is provided with a ventilation window, and the main support structure of the muffler is set. There are intake and exhaust ports and lower air ports. The muffler of the present invention is filled with common noise-absorbing sponge and high-density sponge in the inner bracket, and is equipped with a one-way valve structure, which can maximize the density of the sponge body without affecting the rising speed of the air suspension. The muffler can realize 200Hz-10000Hz broadband For the noise reduction function within the range, a filter is added to the muffler to filter the dust in the inhaled gas, and the dust is taken away during the exhaust process, thereby realizing the self-cleaning function.

Description

technical field [0001] The invention relates to a muffler, in particular to a self-cleaning muffler for air suspension intake and exhaust systems. Background technique [0002] The air suspension can realize the automatic adjustment of the height of the vehicle body, thereby improving the passability and stability of the vehicle, and has become a necessary configuration for high-end models. The vehicle lowers the body height by discharging the high-pressure gas in the air spring. However, the rapid discharge of the high-pressure gas in the air spring often produces a "squeaky" sound, which causes customers to complain about the NVH performance of the vehicle. At present, few mufflers are used in the air suspension exhaust system of models on sale, and some use expansion chamber type mufflers, but this type of muffler has no obvious effect on the gas with a faster flow rate. [0003] The prior art discloses a vehicle muffler, which includes a casing, and the axial ends of th...

Problems solved by technology

[0007] The purpose of the present invention is to provide a self-cleaning air suspension intake and exhaust system muffler to overcome the deflation effect of the existing automobile air suspension system intake and exhaust system muffler on the air suspension system with large flow and fast speed It is not obvious, and the internal cavity is easy to generate structural sound, and it cannot realize the self-cleaning of the inhaled air during the lifting process of the air suspension system
