It provides a smooth driving experience and excellent vehicle handling performance through multiple airbags and related control mechanisms. This suspension system can automatically adjust the airbag pressure according to the vehicle load, driving conditions and road conditions, thereby adjusting the vehicle body height and suspension stiffness to improve the comfort and stability of the vehicle.

[0003] At present, when the multi-airbag air suspension beam assembly on the market is used, the beam and the mounting frame are assembled through cumbersome mounting parts, which makes the overall weight of the multi-airbag air suspension beam assembly heavier, resulting in the multi-airbag air suspension beam assembly being unable to better respond to road changes. Therefore, we propose a weight reduction structure for the multi-airbag air suspension beam assembly. Utility Model Content

[0012] Preferably, one end of the spring is butted against the inner wall of the movable groove, and the other end of the spring is butted against the movable block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the weight reduction structure of the multi-airbag air suspension beam assembly quickly limits the mounting frame through a hollow limit seat that penetrates the beam body, thereby reducing the cumbersome installation structure and facilitating the weight reduction of the multi-airbag air suspension beam assembly; the knob can be shielded by the mutual cooperation between the baffle plate and the protective cover arranged on the outside of the knob, thereby facilitating the protection of the weight reduction structure of the multi-airbag air suspension beam assembly.

[0014] 1. The weight reduction structure of the multi-airbag air suspension crossbeam assembly is as follows: first, the mounting frame is docked above the crossbeam body, and the connecting seat at the bottom of the mounting frame is docked and inserted inside the mounting seat, and then the connected bevel gear set and the connecting rod are driven to rotate synchronously by turning the knob. When the connecting rod rotates, the two outer limit seats can move outward at the same time and penetrate the crossbeam body and are docked and inserted inside the limit groove. The mounting frame is quickly limited by the hollow limit seat penetrating the crossbeam body, thereby reducing the complicated structure of the installation, thereby facilitating the weight reduction of the multi-airbag air suspension crossbeam assembly;

[0015] 2. The weight-reducing structure of the multi-airbag air suspension crossbeam assembly requires that when the knob needs to be turned, the baffle plate is first pulled downward to the extreme position.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a weight reduction structure of a multi-airbag air suspension crossbeam assembly, including a crossbeam body 1, a mounting frame 2 and an airbag body 3.

The inner side of the crossbeam body 1 passes through the limiting seat 7, and a connecting rod 8 is commonly passed through the lower parts of the two limiting seats 7.

[0024] Both ends of the connecting rod 8 are connected to the inner wall of the beam body 1 through bearing seats, and a bevel gear set 9 is sleeved and installed in the middle of the connecting rod 8; a knob 10 connected to the bevel gear set 9 is installed at the bottom of the beam body 1, a guide bar 11 is arranged below the inner wall of the beam body 1, and a guide groove 12 is opened below the limit seat 7; the guide groove 12 is docked at the outside of the guide bar 11, and a shielding cover 13 connected to the beam body 1 is sleeved and installed on the outside of the bevel gear set 9, the cross-sectional size of the guide bar 11 matches the cross-sectional size of the guide groove 12, the limit seat 7 is slidably connected to the guide bar 11 through the guide groove 12, the surface of the connecting rod 8 is provided with a bidirectional thread, and the connecting rod 8 and the limit seat 7 are threadedly connected, and the interior of the limit seat 7 is hollow.

[0025] During specific implementation, the two limit seats 7 in the initial state are both inside the crossbeam body 1. First, the mounting frame 2 is docked on the top of the crossbeam body 1, and the connecting seat 4 at the bottom of the mounting frame 2 is docked and inserted into the inside of the mounting seat 6. Then, the connected bevel gear set 9 is driven to rotate synchronously by turning the knob 10, and the connecting rod 8 rotates synchronously with the rotation of the bevel gear set 9. Since the surface of the connecting rod 8 is provided with a bidirectional thread, and the connecting rod 8 and the limit seat 7 are threadedly connected, the connecting rod 8 can make the two outer limit seats 7 move outward at the same time when it rotates. The moving limit seat 7 moves stably along the surface of the guide strip 11 through the guide groove 12 opened at the bottom until the limit seat 7 passes through the crossbeam body 1 and is docked and inserted into the inside of the limit groove 5. The hollow limit seat 7 passes through the crossbeam body 1 to quickly limit the mounting frame 2, thereby reducing the complicated structure of the installation, thereby facilitating the weight reduction of the multi-airbag air suspension crossbeam assembly.

[0026] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A protective cover 14 connected to the crossbeam body 1 is provided on the outside of the knob 10, and a through slot 15 is provided in the middle of one side of the protective cover 14, and movable slots 16 are provided on both sides of the protective cover 14 close to the through slot 15; a movable block 17 is inserted into the movable slot 16, and a baffle 18 is connected to the outer end of the movable block 17, and the inner wall of the baffle 18 is in contact with the surface of the protective cover 14; a guide rod 19 passes through the middle of the movable block 17, and both ends of the guide rod 19 are connected to the inner wall of the movable slot 16, and a spring 20 is sleeved on the outer side of the guide rod 19; one end of the spring 20 is docked with the inner wall of the movable slot 16, and the other end of the spring 20 is docked with the movable block 17, and the movable block 17 is telescopically extended between the spring 20 and the movable slot 16, and the center line of the movable slot 16 and the through slot 15 are symmetrically distributed.

[0027] During specific implementation, the shielding plate 18 in the initial state completely blocks the outside of the through slot 15. When the knob 10 needs to be turned, the shielding plate 18 is first pulled downward, and the pulled shielding plate 18 drives the connected movable block 17 to move steadily downward along the guide rod 19 inside the movable slot 16, and the spring 20 sleeved on the outside of the guide rod 19 is squeezed by the moving movable block 17 until the shielding plate 18 is pulled downward to the limit position. At this time, the through slot 15 is completely exposed to the outside, and the staff can extend the tool from the through slot 15 to the inside of the protective cover 14 to turn the knob 10. After the turning is completed, the pulled shielding plate 18 can be loosened, and the loosened shielding plate 18 can be automatically reset to the initial position upward by the elastic force of the spring 20. The shielding plate 18 set on the outside of the knob 10 cooperates with the protective cover 14, so as to facilitate the protection of the weight reduction structure of the multi-airbag air suspension beam assembly.

[0028] To sum up, when using the multi-airbag air suspension crossbeam assembly weight reduction structure, first dock the mounting frame 2 on the top of the crossbeam body 1, and drive the bevel gear set 9 and the connecting rod 8 to rotate synchronously by turning the knob 10. When the connecting rod 8 rotates, the two outer limit seats 7 can be moved outward at the same time and inserted into the inner part of the limit groove 5. The hollow limit seat 7 passes through the crossbeam body 1 to quickly limit the mounting frame 2, reducing the cumbersome structure of the installation and achieving the purpose of weight reduction. Finally, the airbag body 3 is installed correspondingly on the top of the mounting frame 2.
