Description

Technical Field

[0001] This utility model belongs to the field of automotive airbag bracket technology, specifically relating to an air suspension airbag bracket. Background Technology

[0002] With the rapid development of my country's expressways, the increase in transportation volume, and the government's increasing emphasis on expressway maintenance, higher requirements are being placed on the handling stability, ride comfort, and safety of automobiles. This will lead to the further promotion of the application of automotive suspension systems. In new energy 6x4 tractor trucks, mainly used for transporting hazardous chemicals, fresh produce, and precision instruments, the rear axle employs an air suspension damping system. Air suspension uses gas springs as the elastic element of the suspension, and its stiffness changes non-linearly. As the spring load increases, the gas inside the airbag is compressed, the air pressure rises, and the spring stiffness increases; conversely, when the spring load decreases, the gas inside the airbag decreases, and the spring stiffness decreases. Therefore, gas springs have ideal elastic characteristics, and air suspension provides good shock absorption. A support mounting structure is often used to mount the airbag on the leaf spring or axle. However, current airbag supports are independent castings and stamped welded parts, which are heavy, have poor durability, and unstable safety performance, making them difficult to meet the needs of modern automotive development.

A square first weight-reducing U-shaped groove is provided between the first and second bases, with rounded inner corners. The outer end faces of both the first and second bases are beveled, with the same inclination angle. A threaded connection hole is vertically formed on the outer end face of both the first and second bases.

[0008] On the other side of the main support, there are a third base and a fourth base. The third base is positioned above the fourth base. A square second weight-reducing U-shaped groove is provided between the third and fourth bases. The inner corners of the second weight-reducing U-shaped groove are rounded. The outer end faces of both the third and fourth bases are beveled, and the outer end faces of the third and fourth bases have the same inclination angle. A threaded connection hole is vertically opened on the outer end face of both the third and fourth bases.

[0009] Two first bases and two second bases are provided between one side of the main support and the base plate. There is a gap between the two first bases. The two first bases are placed on one side of the first weight reduction groove. There is a gap between the two second bases.
