[0043] Reference is made to Figures 1-5 shown;

[0044] The utility model provides an air tank for automobile air suspension, which comprises a cylinder body 1 for storing compressed air, end covers 2 installed on both sides of the cylinder body 1, and air valve one 31 and air valve two 32 respectively arranged on the two end covers 2 for controlling the inflow and outflow of compressed air.

[0045] The cylinder body 1 and the end covers 2 are made of magnesium alloy material.

[0046] The cylinder body 1 is provided with a filter assembly 4.

[0047] The compressed air enters the cylinder body 1 through the air valve one 31, is filtered by the filter assembly 4, and is discharged to the air circuit along the air valve two 32.

[0048] Specifically, the air tank for automobile air suspension comprises a cylinder body 1, end covers 2, and air valves, i.e., air valve one 31 and air valve two 32, installed on the end covers 2. When the air valve one 31 is opened, the compressed air enters the cylinder body 1 from the air valve one 31, and the compressed air in the cylinder body 1 is discharged through the air valve two 32 after the air valve two 32 is opened. During the operation of the vehicle, the compressed air stored in the cylinder body 1 may contain impurities when passing through the brake system. When the impurities enter the air circuit of the air suspension system through the air tank, they may adversely affect the safety of the vehicle or the reliability of the air suspension system. The filter assembly 4 is arranged in part of the space of the cylinder body 1. When the compressed air enters the cylinder body 1, the impurities are filtered by the filter assembly 4 and then discharged to the air circuit, thereby avoiding the adverse effects of the impurities.

[0049] Preferably, the existing air tank is generally made of aluminum material. The cylinder body 1 and the end covers 2 of the air tank are made of magnesium alloy material, which can maintain the performance of the air tank and realize lightweight at the same time.

[0050] A sliding groove 11 is formed in the inner wall of the cylinder body 1.

[0051] The filter assembly 4 is partially installed in the sliding groove 11.

[0052] The filter assembly 4 comprises:

[0053] The mounting seat 41 is in a cylindrical structure.

[0054] The outer wall of the mounting seat 41 is provided with sliding strips 411.

[0055] The sliding strips 411 are embedded in the sliding groove 11 to fix the mounting seat 41 on the inner wall of the cylinder body 1.

[0056] Specifically, the filter assembly 4 has a mounting seat 41, which is in a cylindrical structure, the outer periphery of the mounting seat 41 is matched with the inner periphery of the cylinder body 1, a sliding strip 411 is arranged on the outer wall of the mounting seat 41, and a sliding groove 11 is formed in the inner wall of the cylinder body 1, and the sliding strip 411 is embedded in the sliding groove 11 to mount the mounting seat 41 in the cylinder body 1.

[0057] The filter assembly 4 comprises:

[0058] A plurality of filter plates 42 are distributed at intervals inside the mounting seat 41;

[0059] A filter screen 43 is mounted on one side of the filter plate 42;

[0060] The compressed air is filtered to remove impurities in sequence through the filter plate 42 and the filter screen 43.

[0061] Specifically, the mounting seat 41, the filter plate 42 and the filter screen 43 form an integral adsorption structure, and activated carbon sponge or a high-efficiency air filter can be attached to the mounting seat 41, the filter plate 42 and the filter screen 43. When the compressed air enters the cylinder body 1, it is first adsorbed by the plurality of filter plates 42 and then filtered by the filter screen 43.

[0062] One end of the filter plate 42 is fixed to the inner wall of the mounting seat 41;

[0063] The other end of the filter plate 42 extends downwardly and obliquely;

[0064] The filter plate 42 is inclined downwardly by 20°.

[0065] Specifically, the filter plate 42 is in a plate structure, which is obliquely connected to the inner wall of the mounting seat 41 with an inclination angle of 20°. Each group of filter plates 42 has a certain distance, and adjacent two groups of filter plates 42 are fixedly connected to the two sides of the inner wall of the mounting seat 41 and are in a cross shape. The cross-shaped filter plates 42 increase the contact area with air. When the air moves in the gap between the filter plates 42, the cross-distributed filter plates 42 can effectively adsorb impurities in the compressed air.

[0066] The cylinder body 1 is made by an extrusion process;

[0067] The end cover 2 is made by a stamping and spinning process.

[0068] Preferably, the cylinder body 1 is made by an extrusion process, and the end cover 2 is made by a stamping and spinning process, so that the overall welding seam of the gas storage tank is reduced, the welding cost is reduced, and the risk of leakage is reduced.
