The piston 2, the connecting rod 4 and the air bag 3 are sequentially connected into a whole through bolts and are installed in the housing 1, and the piston 2 can move along the central axis of the front port of the housing 1.
The rear end of the air bag 3 is fixed on the flange blind plate 8, the flange blind plate 8 is connected with the threaded hole 16 of the shell 1 through a bolt, the threaded hole 16 of the shell 1 is M6, the flange blind plate 8 is provided with an air pipe interface 9, one end of an air pipe 10 penetrates through the air pipe interface 9 and is connected with the rear end of the air bag 3, and the other end of the air pipe 10 is connected with the electromagnetic valve 11 on the air outlet 12 of the suspension air blower.
The rear end of the shell 1 is provided with a vent 5, the vent 5 is formed by die sinking and injection molding, the vent 5 is connected with a protrusion 13 on the inner wall of the shell 1 through a groove 14 of the vent, the vent 5 is divided into four flow channels 6 through separation of four reinforcing ribs 7, namely the four flow channels 6 formed by the shell 1, the flange blind plate 8 and the reinforcing ribs 7, and the vent 5 is communicated with the outside and used for exhausting.
