Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to an air suspension muffler. Background Art

[0002] With the rapid development of the automotive industry, consumers' demands for vehicle quality are increasing, with cabin noise levels becoming a key indicator of vehicle quality. Air suspension systems, a key technology for improving ride comfort and handling stability, are facing an increasing noise problem during operation. This noise primarily stems from the rapid flow of high-pressure air in pipes, frictional vibration between components, and turbulence caused by airflow through narrow passages.

[0003] Traditional noise reduction measures for air suspension systems, such as adding sound insulation and optimizing piping layouts, can reduce noise to a certain extent, but they often suffer from limited effectiveness, high costs, or increased system complexity. Therefore, developing a muffler that effectively reduces noise while maintaining the original performance of the air suspension system at a reasonable cost has become a pressing technical challenge. Utility Model Content

[0004] The main purpose of the utility model is to provide an air suspension muffler, which is installed on the air suspension and is used to reduce the noise generated by high-pressure air when the air suspension is in use.

[0005] To achieve the above objectives, the utility model provides an air suspension muffler, which includes a muffler shell, the muffler shell including a muffler cavity and a muffler inlet section connected to the muffler cavity, and the muffler cavity is filled with sponge.

[0006] This air suspension muffler, installed on an air suspension system, directs air flow through the muffler's inlet section, allowing air to flow into the muffler cavity. The sponge within the cavity offers excellent sound absorption and air permeability, effectively absorbing and dissipating noise energy without affecting air flow. The sponge's size and density are precisely matched to the muffler's structure and noise characteristics to achieve optimal noise reduction.

[0007] In one possible implementation, the muffler cavity is provided with a bottom positioning plate and a top positioning plate. Both the bottom positioning plate and the top positioning plate define a sponge fixing groove, into which the sponge is installed. The bottom positioning plate and the top positioning plate define a sponge fixing groove within the muffler cavity, ensuring the sponge's stable position and improving the sound-absorbing effect.

[0008] In one possible implementation, the top of the top positioning plate is bent and passes through the muffler cavity to connect to the muffler inlet section. The top of the top positioning plate is bent and passes through the muffler cavity to connect to the muffler inlet section to form a closed structure to reduce noise leakage.

[0009] In one possible implementation, the outer side wall of the muffler inlet section is provided with a plurality of downwardly inclined annular protrusions. The outer side wall of the muffler inlet section is provided with a plurality of downwardly inclined annular protrusions, which help guide the airflow and reduce turbulence and vibration.

[0010] In a possible implementation manner, the annular protrusion is integrally formed with the muffler inlet.

[0011] In a possible implementation, a muffler outlet section is provided at the bottom of the muffler cavity to ensure smooth discharge of airflow. BRIEF DESCRIPTION OF THE DRAWINGS
