[0033] In this embodiment, the welding installation position of the fixed support 42 of the lifting mechanism is directly in front of the leaf spring support, the rotating support installation position of the lifting mechanism is below the leaf spring support, and the rotating support mounting plate needs to be welded on both sides of the leaf spring support, and the structure is spliced and welded, which has the structural advantage of easy molding and can be manufactured using conventional welding process.

[0034] In this embodiment, the fixed bracket 42 is installed in front of the leaf spring bracket, and the lifting mechanism rotating bracket is installed below the leaf spring bracket. This lifting structure method increases the overall installation height and solves the problem of the lowest point of the lifting mechanism components being too low from the ground.

During this process, the rotating bracket rotates around the pin bolt to a certain angle ( Figure 1 During the rotation, the lifting limit block at the rear end of the rotating bracket directly acts on the leaf spring and lifts the leaf spring. In the process of the leaf spring being lifted, the load-bearing airbag becomes deflated, thereby achieving a height increase of the axle assembly.

[0039] When the axle assembly needs to be lowered, the lifting airbag is deflated and the load-bearing airbag is inflated. During this process, the rotating bracket is rotated around the pin bolt to a certain angle ( Figure 1 During the rotation, the lifting limit block at the rear end of the rotating bracket directly contacts and lifts the leaf spring. During the contact and lifting process, the lifting airbag becomes deflated, thereby realizing the reset of the axle assembly.
