Description

Technical Field

[0001] The present invention belongs to the technical field of lifting and adjusting devices, and specifically relates to an air suspension lever-type axle lifting and adjusting device. Background Art

[0002] The main function of the air suspension lever-type axle lifting and adjusting device is to adjust the vehicle's suspension system to improve its performance and adaptability. It can automatically adjust the height of the axle according to the vehicle's load and driving conditions, ensure that the vehicle body remains level, optimize driving stability, improve the vehicle's load-bearing capacity, adapt to different load requirements, improve driving performance under heavy loads, and provide a smoother driving experience. At the same time, the lever-type design helps to improve handling stability, enabling the vehicle to maintain good handling in various situations. In an uneven environment, adjusting the axle height can increase the ground clearance, enhance the vehicle's passability, and prevent the chassis from scraping.

[0003] During the driving of existing vehicles, the flexibility of adjusting the axle position is relatively insufficient, which makes it more difficult to optimize the vehicle's performance under different driving conditions. During the driving process of the vehicle, especially when facing different road conditions or load changes, ideally, we hope to be able to adjust the position of the axle in a timely manner to improve handling and comfort. However, traditional suspension systems usually rely on a fixed axle height and cannot be quickly adjusted according to real-time needs. This limitation not only reduces the vehicle's adaptability but also affects driving safety.

[0004] Therefore, the present invention provides an air suspension lever-type axle lifting and adjusting device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem of facilitating the lifting and adjustment of the vehicle axle, the present invention proposes an air suspension lever-type axle lifting and adjusting device.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: An air suspension lever-type axle lifting and adjusting device according to the present invention includes an axle body and a load-bearing plate. Support arms are connected to both ends of the axle body, and wheels are fixedly connected to the support arms. A support plate is arranged on the side of the load-bearing plate, and a frame is fixedly installed on the top of the support plate. A lever assembly is arranged inside the frame. A support frame is fixedly installed on the support plate, and an airbag is fixedly installed inside the support frame. A driving assembly is arranged on the support frame. A compression assembly is arranged inside the support plate. A downward pressure airbag is arranged inside the frame. A limiting assembly is arranged on the axle body, and cleaning assemblies are arranged at both ends of the axle body.

[0007] By adopting the above technical solution, the driving component is moved to compress the airbag through the cooperation of the compression component, and then the air stored inside the airbag will flow into the lower pressing airbag. The expansion of the volume of the lower pressing airbag will drive the movement of the lever component, and the movement of the lever component will drive the movement of the axle body, so that the position of the axle body can be adjusted. By adjusting the change in the height of the axle body, the contact angle between the wheel and the ground and the track width can be directly affected, thereby affecting the traction force, braking effect and handling performance of the vehicle. According to the load change or road conditions, adjusting the axle height can ensure that the vehicle maintains the best handling and stability under different conditions. Especially in the case of heavy load or off-road, the performance of the suspension system can be optimized, road bumps can be absorbed, so as to improve the riding comfort, and enhance its ability to pass obstacles, and avoid uneven wear of suspension components or tires caused by improper axle height, thereby extending the service life of the vehicle.

[0008] Preferably, mounting holes are symmetrically arranged on the load-bearing plate, a connecting frame is fixedly mounted on the side surface of the axle body, the limiting component includes a limiting cylinder, a cylinder, a moving groove and a positioning mechanism.

Furthermore, when the driving plate moves, it will push the driving rod upward. When the driving rod moves, it will drive the compression block to move. Furthermore, the compression block will compress the air inside the compression groove. When the driving plate is no longer in contact with the driving rod, the second spring will reset and push the compression block to reset.

[0020] Preferably, a communication pipe is installed on the compression groove, and the other end of the communication pipe is communicated with the cleaning assembly.

[0021] By adopting the above technical solution, when the air inside the compression groove is compressed by the upward movement of the compression block, the compressed air flows into the communication pipe.

[0026] 1. An air suspension lever - type axle lifting and adjusting device according to the present invention facilitates the adjustment of the height of the axle body through the provided airbag and drive plate.

By adjusting the change in the height of the axle body, it can directly affect the contact angle between the wheel and the ground and the wheelbase, thereby affecting the traction force, braking effect, and handling performance of the vehicle. According to the load change or road conditions, adjusting the axle height can ensure that the vehicle maintains the best handling and stability under different conditions. Especially in the case of heavy loads or off - road, it can optimize the performance of the suspension system, absorb road bumps, thereby enhancing the riding comfort, and also enhancing its ability to pass obstacles, avoiding uneven wear of the suspension components or tires caused by improper axle height, thus extending the service life of the vehicle and enabling the vehicle to better adapt to different driving environments.

[0027] 2. An air suspension lever - type axle lifting and adjusting device according to the present invention facilitates the cleaning treatment of the wheel hub through the provided compression groove and air injection holes. When one end of the drive plate moves downward, through the cooperation of the support shaft, the other end of the drive plate will move upward. Then, when the drive plate moves, it will push the drive rod upward. When the drive rod moves, it will drive the compression block to move. Then, the compression block will compress the air inside the compression groove.

Detailed implementation manners

[0037] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

Support arms 2 are connected to both ends of the axle body 1. The support arms 2 are fixedly connected to wheels 3. A support plate 17 is provided on the side of the load - bearing plate 4. A frame 28 is fixedly installed on the top of the support plate 17. A lever assembly is arranged inside the frame 28. A support frame 18 is fixedly installed on the support plate 17. An airbag 19 is fixedly installed inside the support frame 18. A driving assembly is arranged on the support frame 18. A compression assembly is arranged inside the support plate 17. A downward - pressing airbag 33 is arranged inside the frame 28. A limiting assembly is arranged on the axle body 1. Cleaning assemblies are arranged at both ends of the axle body 1. When using the air suspension lever - type axle lifting and adjusting device, after the load - bearing plate 4 is fixedly connected to the vehicle body through the mounting holes 5, the axle body 1 is limit - connected through the cooperation of the limiting cylinder 7 and the cylinder 8. The axle body 1 installs tires through the wheels 3 and can thus move on the road surface. When adjusting the position of the axle body through the air suspension lever - type axle lifting and adjusting device, the driving assembly moves and compresses the airbag 19 through the cooperation of the compression assembly. Then, the air stored inside the airbag 19 flows into the downward - pressing airbag 33. The volume expansion of the downward - pressing airbag 33 drives the lever assembly to move. The movement of the lever assembly drives the axle body 1 to move, and thus the position of the axle body 1 can be adjusted. By adjusting the height change of the axle body 1, it can directly affect the contact angle between the wheel and the ground and the wheelbase, thereby affecting the traction force, braking effect, and handling performance of the vehicle. According to the load change or road conditions, adjusting the axle height can ensure that the vehicle maintains the best handling and stability under different conditions. Especially in the case of heavy loads or off - road, it can optimize the performance of the suspension system, absorb road bumps, thereby improving the riding comfort and enhancing its ability to pass obstacles. It can also avoid uneven wear of the suspension components or tires caused by improper axle height, thus extending the service life of the vehicle and enabling the vehicle to better adapt to different driving environments. When the lever assembly moves, it compresses air in cooperation with the compression groove 34. The compressed air flows into the cleaning assembly, and the wheels 3 can be cleaned through the cleaning assembly, thereby improving the cleanliness of the wheels 3.

[0039] As Figure 1 , Figure 2 and Figure 7As shown, mounting holes 5 are symmetrically arranged on the load-bearing plate 4. A connecting frame 6 is fixedly installed on the side of the axle body 1. The limiting assembly includes a limiting cylinder 7, a cylinder 8, a moving slot 9 and a positioning mechanism. The limiting cylinder 7 is fixedly installed on the top of the axle body 1.

Two load-bearing frames 43 are fixedly installed on the top of the axle body 1. The load-bearing plate 4 is connected to the vehicle body through the mounting holes 5. When the axle body 1 moves, it will drive the limiting cylinder 7 to move. The limiting cylinder 7 slides on the cylinder 8. The cooperation between the limiting cylinder 7 and the cylinder 8 enables the axle body 1 to move smoothly. The position of the limiting cylinder 7 can be positioned through the cooperation of the positioning mechanism, and then the position of the axle body 1 can be positioned.

[0040] As Figure 7 shown, the positioning mechanism includes a positioning shaft 12, a magnetic attraction block 13, a guiding shaft 14, a return spring 15 and an electromagnet 16. The positioning shaft 12 is inserted into the positioning hole 11, and the other end of the positioning shaft 12 extends into the moving slot 9. The magnetic attraction block 13 is arranged inside the moving slot 9, and one end of the positioning shaft 12 is fixedly connected to the magnetic attraction block 13.

The return spring 15 is arranged around the guiding shaft 14. The electromagnet 16 is fixedly installed inside the moving slot 9, and the electromagnet 16 is located on one side of the magnetic attraction block 13. When adjusting the movement of the axle body 1, the electromagnet 16 works to generate magnetic force. The magnetic force attracts the magnetic attraction block 13 to move. The movement of the magnetic attraction block 13 drives the positioning shaft 12 to move into the moving slot 9. Furthermore, when the cylinder 8 moves, it will drive the limiting block 10 to slide inside the limiting cylinder 7. After the limiting block 10 moves to one side of the predetermined position, the positioning hole 11 will correspond to the positioning shaft 12. Then, the electromagnet 16 stops working. Furthermore, the return spring 15 resets and pushes the magnetic attraction block 13 to move. The movement of the magnetic attraction block 13 pushes the positioning shaft 12 to move. After the positioning shaft 12 moves into the positioning hole 11, the position of the limiting block 10 can be positioned.

[0041] As Figure 5As shown in the figure, the driving assembly includes a sliding groove 20, a driving motor 21, a threaded lead screw 22, a sliding block 24, a threaded ring 25, and a push plate 26. The sliding groove 20 is fixedly installed on the support frame 18. The driving motor 21 is fixedly installed inside the sliding groove 20. The threaded lead screw 22 is rotatably arranged inside the sliding groove 20. The sliding block 24 is arranged inside the sliding groove 20. The threaded ring 25 is fixedly installed inside the sliding block 24, and the threaded lead screw 22 is threadedly connected to the threaded ring 25. The push plate 26 is arranged below the airbag 19 and is fixedly connected to the sliding block 24. A guide rod 23 is fixedly installed inside the sliding groove 20, and the guide rod 23 passes through the sliding block 24. When the driving motor 21 operates, it will drive the threaded lead screw 22 to rotate. When the threaded lead screw 22 rotates, it will cause the threaded ring 25 to move. The movement of the threaded ring 25 will drive the sliding block 24 to move. Furthermore, the movement of the sliding block 24 can drive the push plate 26 to move synchronously. The movement of the push plate 26 will squeeze the airbag 19, and the gas stored inside the airbag 19 will flow.

[0042] As Figure 5 shown, a connecting head 27 is fixedly installed at the bottom of the airbag 19, and the connecting head 27 passes through the push plate 26 and is connected to the pressing airbag 33 through a pipeline. When the airbag 19 is squeezed, the gas under pressure will flow into the pressing airbag 33 through the cooperation of the connecting head 27 and the pipeline. Furthermore, the volume of the pressing airbag 33 will expand, and then the lever assembly will be driven to move. The movement of the lever assembly will lift and adjust the position of the axle body 1 of the vehicle.

[0043] As Figure 4 shown, the lever assembly includes a support shaft 29, a driving plate 30, a connecting ring 31, and a first spring 32. The support shaft 29 is fixedly installed inside the frame 28. The driving plate 30 is arranged inside the frame 28, and the support shaft 29 passes through the driving plate 30. The connecting ring 31 is fixedly installed at one end of the driving plate 30, and the connecting ring 31 is movably connected to the connecting frame 6. One end of the first spring 32 is fixedly connected to the bottom of the driving plate 30, and the other end of the first spring 32 is fixedly connected to the inner wall of the frame 28. When the volume of the pressing airbag 33 expands, it will drive the driving plate 30 to move. The movement of the driving plate 30 will make an arc movement around the support shaft 29. When the driving plate 30 moves, the position of the axle body 1 will be lifted and adjusted through the cooperation of the connecting ring 31 and the connecting frame 6.

[0044] As Figure 6As shown in the figure, the compression component includes a compression groove 34, a second spring 35, a compression block 36, a guide cylinder 37, and a drive rod 38. The compression groove 34 is fixedly installed inside the frame 28. The second spring 35 is fixedly installed inside the compression groove 34. The compression block 36 is arranged inside the compression groove 34. The guide cylinder 37 is fixedly installed at the bottom of the compression groove 34 and is communicated with the compression groove 34. The drive rod 38 is inserted inside the guide cylinder 37. When one end of the drive plate 30 moves downward, the other end of the drive plate 30 will move upward through the cooperation of the support shaft 29. Thus, when the drive plate 30 moves, it will push the drive rod 38 upward. When the drive rod 38 moves, it will drive the compression block 36 to move. Then, the compression block 36 will compress the air inside the compression groove 34. When the drive plate 30 and the drive rod 38 are no longer in contact, the second spring 35 will reset and push the compression block 36 to reset.

[0045] As Figure 6 shown, a connecting pipe 40 is installed on the compression groove 34, and the other end of the connecting pipe 40 is communicated with the cleaning component. A limiting shaft 39 is fixedly installed at the bottom of the compression block 36, and the limiting shaft 39 penetrates through the compression groove 34. When the compression block 36 moves upward to compress the air inside the compression groove 34, the compressed air will flow into the connecting pipe 40. Then, through the connecting pipe 40, the compressed air will flow into the cleaning component.

[0046] As Figure 1 and Figure 2 shown, the cleaning component includes a flow dividing groove 41 and air spraying holes 42. The flow dividing groove 41 is embedded inside the axle body 1. The air spraying holes 42 are arranged in an array on the flow dividing groove 41, and the other end of the connecting pipe 40 is communicated with the flow dividing groove 41. After the compressed air flows through the connecting pipe 40 and enters the flow dividing groove 41, the air will flow to the surface of the wheel hub 3 through the air spraying holes 42, which can facilitate the cleaning of the wheel hub 3. The air flowing to the surface of the wheel hub 3 through the air spraying holes 42 helps to remove dust, mud, and other dirt accumulated on the wheel hub, improves the cleaning efficiency, and can quickly and effectively remove the dirt.

[0047] Working principle: First, when the position of the axle body is adjusted by the air suspension lever-type axle lifting and adjusting device, the driving motor 21 works to drive the threaded lead screw 22 to rotate. When the threaded lead screw 22 rotates, the threaded ring 25 will move. When the threaded ring 25 moves, it will drive the sliding block 24 to move. Furthermore, the movement of the sliding block 24 can drive the push plate 26 to move synchronously. The movement of the push plate 26 will squeeze the airbag 19, and the gas stored inside the airbag 19 will flow. Then, the air stored inside the airbag 19 will flow into the lower pressure airbag 33. The volume of the lower pressure airbag 33 expands, which will drive the driving plate 30 to move. The movement of the driving plate 30 will make an arc movement around the support shaft 29. When the driving plate 30 moves, through the cooperation of the connecting ring 31 and the connecting frame 6, the position of the axle body 1 will be lifted and adjusted. When the axle body 1 moves, it will drive the limiting cylinder 7 to move. The limiting cylinder 7 slides on the cylinder 8. The cooperation between the limiting cylinder 7 and the cylinder 8 will make the axle body 1 move smoothly. Through the cooperation of the positioning mechanism, the position of the limiting cylinder 7 can be positioned, and then the position of the axle body 1 can be positioned. When adjusting the movement of the axle body 1, the electromagnet 16 works to generate magnetic force. The magnetic force attracts the magnetic block 13 to move. The movement of the magnetic block 13 will drive the positioning shaft 12 to move into the movable slot 9. Then, when the cylinder 8 moves, it will drive the limiting block 10 to slide inside the limiting cylinder 7. After the limiting block 10 moves to one side of the predetermined position, the positioning hole 11 will correspond to the positioning shaft 12. Then, make the electromagnet 16 stop working. Furthermore, the reset spring 15 resets to push the magnetic block 13 to move. The movement of the magnetic block 13 will push the positioning shaft 12 to move. After the positioning shaft 12 moves into the positioning hole 11, by adjusting the height change of the axle body 1, it can directly affect the contact angle between the wheel and the ground and the wheelbase, thereby affecting the traction force, braking effect, and handling performance of the vehicle. According to the load change or road conditions, adjusting the axle height can ensure that the vehicle maintains the best handling and stability under different conditions. Especially in the case of heavy loads or off-road, it can optimize the performance of the suspension system, absorb road bumps, thereby improving the riding comfort, and enhancing its ability to pass obstacles. Avoid uneven wear of suspension components or tires caused by improper axle height, thereby extending the service life of the vehicle, enabling the vehicle to better adapt to different driving environments. When one end of the driving plate 30 moves downward, through the cooperation of the support shaft 29, the other end of the driving plate 30 will move upward. Then, when the driving plate 30 moves, it will push the driving rod 38 to move upward. When the driving rod 38 moves, it will drive the compression block 36 to move. Furthermore, the compression block 36 will compress the air inside the compression groove 34. When the compression block 36 moves upward to compress the air inside the compression groove 34, the compressed air will flow into the communication pipe 40. After flowing into the diversion groove 41 through the cooperation of the communication pipe 40, the air will flow to the surface of the wheel hub 3 through the air injection holes 42, which can facilitate the cleaning treatment of the wheel hub 3. The air flowing to the surface of the wheel hub 3 through the air injection holes 42 helps to remove dust, dirt, and other contaminants accumulated on the wheel hub, improving the cleaning efficiency.It can quickly and effectively remove dirt.
