In the above technical solution, a more specific solution is: the thrust rod seat is a thick plate with notches at two sides corresponding to the corresponding parts of the axle housing; and a stabilizer bar mounting threaded hole and a thrust rod mounting threaded hole which are respectively used for mounting the transverse stabilizer bar and the lower thrust rod are processed on two opposite sides of the thrust rod seat.

Further: lower saddle upper portion sets up two relative lower installation stoppers that are used for fixing on the axle housing, and the lower part is equipped with installation protruding portion and the breach that corresponds other positions of axle housing.

Further: two opposite upper mounting limit blocks for fixing on the axle housing are arranged at the lower part of the air bag support; and an air bag mounting threaded hole for mounting an air bag is processed in the center of the top surface of the air bag support.

Further: the connecting reinforcing plate is a rectangular plate and is used for connecting the airbag support with the shock absorber support and the altitude valve support to play a role in fixing and reinforcing.

Further: and a damping support mounting hole and a height valve support mounting hole which are respectively used for mounting the damper and the height valve support are processed on the damper support and the height valve support.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:

the invention integrates the thrust rod seat, the lower bracket, the air bag support, the shock absorber support and the altitude valve support into a steel support body, and the concentrated components are respectively provided with the air bag mounting threaded hole, the transverse stabilizer bar mounting hole, the altitude valve support hole and the lower thrust rod connecting threaded hole, so that the space and the number of parts required by the mounting of the suspension are greatly reduced, the structural design is reasonable, the cost is reduced, the overall mass is smaller, and the lightweight design of the whole vehicle is facilitated; meanwhile, the assembly problem possibly caused by excessive parts and the interference and abnormal sound problem in the running process of the vehicle are reduced, so that the installation is simpler and more reliable, and the after-sales maintenance is more convenient to disassemble.
