Air suspension system

An air suspension system, comprising a frame for mounting a vehicle body, a bridge housing for mounting wheels, and air springs, shock absorbers, a connecting rod frame and a thrust module connected between the frame and the bridge housing, characterized in that:

• the frame including a frame longitudinal beam and a frame crossbeam transversely connecting the frame longitudinal beam;
• the bridge housing including a drive bridge housing;
• the drive bridge housing including a bridge housing body, half-axle sleeves located on both sides of the bridge housing body, and a first support arm extending from the half-axle sleeves along the periphery of the half-axle sleeves in a first direction and a third support arm extending from the half-axle sleeves along the periphery of the half-axles in a second direction away from the first direction;
• the connecting rod frame including a third connecting rod frame;
• the third connecting rod frame including a first frame arm and a first rotating arm pivotally connected to the first frame arm;
• the other end of the first frame arm away from the first rotating arm being connected to the frame longitudinal beam;
• the other end of the first rotating arm away from the first frame arm being connected to the bridge housing body;
• the shock absorbers including a first shock absorber;
• one end of the first shock absorber being connected to the frame longitudinal beam, and the other end being connected to the third support arm;
• the air springs including a first air spring distributed in the first longitudinal position and a third air spring distributed in the third longitudinal position;
• one side of the first air spring being installed on the first support arm, and the other side being installed on the frame longitudinal beam;
• one side of the third air spring being installed on the third support arm, and the other side being installed on the frame longitudinal beam;
• one side of the first thrust module being connected to the bridge housing body, and the other side being connected to the frame crossbeam;
• the bridge housing is integrally cast and includes a circumferentially extending brake base plate;
• the brake base plate is used to install the brake shoe of a drum brake or to install the brake caliper bracket of a disc brake.
