[0002] The air suspension itself is light in weight and makes almost no noise when operating. It is widely used in trailers that transport dangerous goods and precision instruments.

[0003] Currently, air suspension systems include a guide arm bracket, a guide arm, a shock absorber, and an airbag. One end of the guide arm is hinged to the guide arm bracket, and the other end of the guide arm is extended with a curved airbag mounting portion for mounting the airbag. The guide arm is secured to the vehicle axle via a vertically arranged bridge support upper cover plate, a bridge support, a bridge support lower cover plate, and bolts. The curved airbag mounting portion and the guide arm bracket are located on either side of the axle. This type of air suspension system, with the curved airbag mounting portion extending from one end of the guide arm for mounting the airbag, increases the length and manufacturing cost of the guide arm, as well as its weight, thereby reducing vehicle fuel economy and increasing manufacturing costs.

[0026] Specifically, during installation, the fixing clamp 1 4 is first fixed on the axle 1, and then the fixing seat 3 and the guide arm 6 are superimposed and placed against the fixing clamp 1 4, and then the fixing clamp 2 5 is pressed against the fixing seat 3 and fixed to the axle 1, and the guide arm 6 and the fixing seat 3 are fixed synchronously through the fixing assembly 7, so that the suspension airbag body 2 is installed on the axle 1, so that there is no need to extend a curved airbag mounting portion for mounting the airbag at one end of the guide arm 6, which effectively reduces the length and weight of the guide arm 6, thereby reducing the manufacturing cost of the guide arm 6 and the overall weight of the suspension, thereby improving the fuel economy of the vehicle.

[0027] Reference Figure 3 The fixing assembly 7 includes a plurality of positioning columns 71 and positioning holes 72. The positioning columns 71 are respectively fixedly mounted on the upper side wall of the fixing clamp 1 4 and the fixing clamp 2 5 on the opposite side. The positioning holes 72 are opened on the outer side wall of the guide arm 6. The upper side wall of the fixing clamp 1 4 and the fixing clamp 2 5 on the opposite side is symmetrically opened with positioning grooves 8. The bottom end of the fixing base 3 is inserted into the interior of the positioning groove 8. The fixing assembly 7 also includes a connecting hole 74, which is opened at the lower side wall of the fixing base 3.

[0028] Specifically, by passing the positioning column 71 through the connecting hole 74 and the positioning hole 72, the guide arm 6 and the fixing seat 3 can be quickly fixed, thereby realizing the rapid installation of the guide arm 6, the fixing seat 3 and the axle 1. When disassembly and maintenance are required later, it is only necessary to open the fixing clamp 2 5 to remove the guide arm 6 and the suspension airbag body 2.

[0030] Specifically, when installing the second fixing clamp 5, the connecting column 77 is aligned and inserted into the fixing hole plate 75, so that the first fixing clamp 4 and the second fixing clamp 5 are connected through the fixing hole plate 75, thereby improving the stability of the two.

[0031] Reference Figure 4 - Figure 5The suspension airbag body 2 includes a suspension airbag component 21 and two upper and lower fixed supports 22. The lower fixed support 22 is welded to the fixed seat 3. The fixed support 22 includes a connecting layer 1 221 and a connecting layer 2 222. The connecting layer 1 221 and the connecting layer 2 222 are rotatably connected at the center of the opposite side by an axis.

[0032] Specifically, when the suspension airbag component 21 is connected to the fixed support 22, the locking column 23 is inserted into the interior of the slot 26 through the card slot 25, and then the connecting layer 1 221 is rotated so that the connecting layer 1 221 can be rotated and inserted into the locking slot 24, thereby limiting the locking column 23. Finally, the connecting layer 1 221 and the connecting layer 2 222 are fixed by a single set of bolt components 10, so that the locking column 23 and the fixed support 22 are quickly fixed, thereby reducing the number of bolt components 10 and facilitating the later disassembly and assembly of the suspension airbag body 2.

[0033] Reference Figure 5 The outer side wall of the connecting layer 1 221 is fixedly connected with a positioning member 11, and the top of the connecting layer 2 222 is fixedly connected with a positioning member 2 12;

[0035] Working principle: When the device is needed, during installation, the fixing clamp 1 4 is first fixed to the axle 1, and then the fixing seat 3 and the guide arm 6 are superimposed and placed against the fixing clamp 1 4. Then, the fixing clamp 2 5 is pressed against the fixing seat 3 and fixed to the axle 1. The guide arm 6 and the fixing seat 3 are fixed synchronously by the fixing assembly 7, so that the suspension airbag body 2 is installed on the axle 1. In this way, it is no longer necessary to extend a curved airbag mounting portion at one end of the guide arm 6 to install the airbag, effectively reducing the length and weight of the guide arm 6, thereby reducing the manufacturing cost of the guide arm 6 and the overall weight of the suspension, and improving the fuel economy of the vehicle. By passing the positioning column 71 through the connecting hole 74 and the positioning hole 72, the guide arm 6 and the fixing seat 3 can be quickly fixed, thereby achieving rapid installation of the guide arm 6, the fixing seat 3 and the axle 1. When disassembly and maintenance are required later, only the fixing clamp 2 5 needs to be opened to remove the guide arm 6 and the suspension airbag body 2. When the suspension airbag component 21 is connected to the fixed support 22, the locking column 23 is inserted into the interior of the slot 26 through the card slot 25, and then the connecting layer 1 221 is rotated so that the connecting layer 1 221 can be rotated and inserted into the locking slot 24, thereby limiting the locking column 23. Finally, the connecting layer 1 221 and the connecting layer 2 222 are fixed by a single set of bolts 10, so that the suspension airbag component 21 and the fixed support 22 are quickly fixed, thereby reducing the number of bolts 10 and facilitating the later disassembly and assembly of the suspension airbag body 2.
