[0022] See Figures 1 to 4 This embodiment discloses a housing for an air spring, comprising a housing body 1 and a cover body 2, wherein the cover body 2 is provided on the top of the housing body 1.

[0023] A first annular inner cavity is provided on the shell body 1, and a plurality of first connecting ribs 11 are arranged at intervals on the first annular inner cavity so that the first annular inner cavity forms a plurality of first chambers 101. A first groove 102 is provided on the first connecting rib 11 so that adjacent first chambers 101 are connected to each other. A first breathing hole 103 connected to the first chamber 101 is provided on the shell body 1, and a first chamber 101 is spaced apart between adjacent first breathing holes 103.

[0024] The cover body 2 is provided with a second annular inner cavity, and second connecting ribs 21 corresponding to the position and number of the first connecting ribs 11 are arranged at intervals on the second annular inner cavity, so that a plurality of second chambers 201 are formed on the second annular inner cavity, and the second chambers 201 are correspondingly communicated with the first chamber 101, and a second groove 202 is provided on the second connecting rib 21 so that adjacent second chambers 201 are communicated with each other, and the cover body 2 is provided with a second breathing hole 203 connected with the second chamber 201, so that the second breathing hole 203 is communicated with the first chamber 101, and there is a first chamber 101 between adjacent second breathing holes 203, and the first breathing hole 103 and the second breathing hole 203 are vertically staggered.
