Silencer for air suspension intake and exhaust system

Abstract

The invention relates to a silencer for an air suspension intake and exhaust system. The silencer comprises a silencer body, a shell and a silencing structure, wherein the silencing structure is arranged in the silencer body, the shell is fixed to the exterior of the silencer body, a cavity is formed between the shell and the silencer body, a sealing ring is arranged between the shell and the silencer body, an air hole I is formed in the silencer body, a connecting port connected with an air suspension system is formed in the bottom of the silencer body, a clamping device is arranged between the connecting port and the air hole I, and an air hole II is formed in the clamping device. According to the silencer, the silencer body composed of an upper half shell and a lower half shell is filled with high-density sponge, and the pore effect on the sponge is ingeniously utilized for reducing the flow speed of high-speed gas, so that the flowing noise of the high-speed gas is reduced, and thegood noise reduction effect in an air leakage process of the air suspension system is achieved; the cavity formed by the two structural parts is used for achieving the further silencing effect, so that the cavity in the silencer is prevented from generating a structural sound of the cavity; and the structure is simpler.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler suitable for an air intake and exhaust system of an automobile air suspension system. 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,...
