Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to an active suspension structure of a distributed drive vehicle. Background Art

[0002] The active suspension system is a new type of suspension system controlled by a computer that has been developed in the past decade. The active suspension system has the function of controlling the movement of the vehicle body. When the inertia of the car during braking or turning causes the spring to deform, the active suspension system will generate a force that opposes the inertia and reduce the change in the position of the vehicle body. Active suspension can be divided into electromagnetic suspension, air suspension, spring suspension, etc.

[0003] The air suspension system is an advanced product popular in the automotive industry of developed countries today. In developed countries, 100% of medium-sized and larger buses use air suspension systems, and more than 40% of trucks, trailers and tractors use air suspension systems.

[0034] like Figure 6 The alignment component 5 includes a transfer device 22 and an isolation device 23. The transfer device 22 is fixedly mounted on the top of the isolation device 23 to support the transfer device 22 to work.

[0035] like Figure 7 The transmission device 22 includes a second spring 24, a first piston rod 25, an L-shaped gas cylinder 26, a second piston rod 27, a synchronous displacement rod 28, a guide sliding key 29, a support side plate 30 and a protective cover plate 31.

The synchronous alignment plate 32 is vertically aligned with the extension frame 16, so that when the extension frame 16 moves downward, it will drive the synchronous alignment plate 32 to squeeze the first piston rod 25 to move toward the inside of the L-shaped gas cylinder 26.

[0036] like Figure 8 The isolation device 23 includes a hydraulic pipeline 33, a directional guide rail 34, a supporting side frame 35 and a rack 36. The hydraulic pipeline 33 is fixedly installed on one side of the top of the supporting side frame 35, and the rack 36 is symmetrically fixedly installed on the other side of the top of the supporting side frame 35. The directional guide rail 34 is fixedly installed on the front and rear tops of the supporting side frame 35, and the guide sliding key 29 slides in the card groove inside the directional guide rail 34, so that the protective cover plate 31 can be supported to move in a straight line.

[0037] The extension frame 16 is fixedly mounted on the bottom end of the guide slide rod 10, the first push ring 17 and the second push ring 19 are respectively fitted with the outer ring surface of the vibration sensor 14, the L-shaped air cylinder 26 is fixedly mounted on the front and rear ends of the supporting side frame 35 close to the rack 36, the guide sliding key 29 is slidably inserted into the inside of the directional guide rail 34, and the vibration sensor 14 is fixedly mounted on the top end of the supporting side frame 35 close to the rack 36, which can support the air shock absorber 9 to work.

[0038] The interior of the support sleeve 12 is set in a hollow state, and the guide slide rod 10 passes through the interior of the support sleeve 12, the transmission gear 21 is vertically aligned with the rack 36, the interior of the L-shaped air cylinder 26 is set in a hollow state, and a closed cavity is formed between the first piston rod 25, the L-shaped air cylinder 26 and the second piston rod 27, the synchronous alignment plate 32 is vertically aligned with the bottom end of the extension frame 16, the nylon brush 20 is vertically aligned with the surface of the vibration sensor 14, and a slot is provided inside the directional guide rail 34, which can support the protective cover 31 to move in a straight line.

[0039] The working principle of the embodiment 1 is as follows: when in use, the coupling component 2 and the air shock absorber 9 are first connected to the external frame respectively, and then the wheel hub 3 is connected to the driving device of the frame. At the same time, when the car is driving on a relatively bumpy gravel road, the comfort of the car can be adjusted by setting the air shock absorber 9. At the same time, when the air shock absorber 9 is compressed, it can drive the guide slide bar 10 to move inside the support sleeve 12, thereby driving the extension frame 16 and the first push ring 17 to move downward. The first push ring 17 is fitted with the outer ring surface of the vibration sensor 14, so that when the first push ring 17 moves downward, impurities attached to the outer ring surface of the vibration sensor 14 can be removed. At the same time, the second push ring 19 is fixedly installed at the bottom end of the connecting rod 18. When the first push ring 17 moves, it also drives the second push ring 19 to move downward at the same time, so as to drive the transmission gear 21 to move along the surface of the rack 36, so that when the second push ring 19 moves, it drives the nylon brush 20 to rotate synchronously through the transmission gear 21. At the same time, when the second push ring 19 drives the nylon brush 20 to move on the surface of the vibration sensor 14, the nylon brush 20 fits with the surface of the vibration sensor 14, so that the surface of the vibration sensor 14 will be cleaned again, thereby improving the cleaning efficiency of the surface of the vibration sensor 14. In addition, when the air shock absorber 9 is working, the closed slide plate 8 and the alignment sealing plate 15 are located on the outer ring of the air shock absorber 9, so that gravel or other objects from the outside can directly collide with the air shock absorber 9. In addition, the closing slide 8 can slide inside the alignment sealing plate 15. Therefore, the closing slide 8 and the alignment sealing plate 15 can perform protection work when the air shock absorber 9 is working. When the extension frame 16 moves downward, the synchronous alignment plate 32 can be squeezed to drive the first piston rod 25 to move toward the inside of the L-shaped air cylinder 26, so that the second piston rod 27 can be driven to move toward the end away from the protective cover 31. When the second piston rod 27 moves, the supporting side plate 30 and the protective cover 31 can be driven to move along the top of the supporting side frame 35 through the synchronous displacement rod 28, so that the protective cover 31 can be moved to align with the vibration sensor 14, so that the surface of the vibration sensor 14 can be isolated and protected. When the protective cover 31 moves, the guide slide The key 29 moves in the card slot inside the directional guide rail 34, so that the protective cover plate 31 can be supported to move in a straight line, thereby improving the docking accuracy between the protective cover plate 31 and the vibration sensor 14, so that the protective cover plate 31 temporarily protects the vibration sensor 14. Afterwards, when the air shock absorber 9 swells and resets, the air shock absorber 9 will drive the guide slide bar 10 to move upward from the inside of the support sleeve 12, so that the first push ring 17 and the second push ring 19 can be reset upward along the outer ring surface of the vibration sensor 14. When the synchronous alignment plate 32 loses the extrusion force, the elasticity of the second spring 24 will drive the first piston rod 25 to move upward and reset quickly, so that the second piston rod 27 moves toward the inside of the L-shaped air cylinder 26 again, so that the protective cover plate 31 can be driven to reset.The protective cover plate 31 can protect the hydraulic pipeline 33 and complete the protection work when the hydraulic pipeline 33 is working. When the device is in use, the charging level inside the air shock absorber 9 drives the guide slide bar 10 to move downward, and then drives the first push ring 17 and the second push ring 19 to clean the surface of the vibration sensor 14, thereby improving the sensitivity of the vibration sensor 14. In addition, when the first push ring 17 and the second push ring 19 clean the surface of the vibration sensor 14, the second piston rod 27 can drive the protective cover plate 31 to move to the front of the vibration sensor 14, thereby realizing the temporary protection work of the surface of the vibration sensor 14, preventing the vibration sensor 14 from being damaged by the splashing gravel from the outside, and completing the protection and cleaning work of the vibration sensor 14.

[0040] Example 2

[0041] On the basis of Example 1, Fig. 9 As shown, the support side frame 35 also includes an extension plate 37, a guide groove 38 and a support cross frame 39. The guide groove 38 is symmetrically opened on the top of the support side frame 35 close to the rack 36, the extension plate 37 is symmetrically fixedly installed on the inner top of the guide groove 38, and the support cross frame 39 is fixedly installed on the top of the guide groove 38 away from the extension plate 37.

[0042] When implementing this embodiment, the vibration sensor 14 is fixedly installed on the top of the supporting cross frame 39, and the inner size of the guide groove 38 is larger than the diameter of the vibration sensor 14, so that impurities falling from the vibration sensor 14 will enter the surface of the guide groove 38, and the surface of the guide groove 38 is inclined at 45°, so that the impurities will slide and fall along the surface of the guide groove 38. At the same time, through the setting of the extension plate 37, the rack 36 can be supported for transmission work, and the vibration sensor 14 is vertically aligned with the guide groove 38, so that the impurities can be discharged smoothly, avoiding excessive impurities from remaining on the surface of the supporting side frame 35.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
