Referring to fig. 1 and 2, an air suspension system 100 according to an embodiment of the present disclosure includes a frame 10, a driving device 20, an air suspension 30, and an air pressure supply device 40. The driving device 20 is provided on the frame 10. The pneumatic suspension 30 is disposed on the vehicle frame 10, and the pneumatic suspension 30 is connected to the driving device 20. The air pressure supply device 40 is arranged on the frame 10, the air pressure supply device 40 is connected with the air pressure suspension 30, and the air pressure supply device 40 is used for inputting air to the air pressure suspension 30.
Referring to fig. 3, the air suspension system 100 according to the embodiment of the present application may be applied to a vehicle 1000, and specifically, the vehicle 1000 includes a vehicle body 200 and the air suspension system 100, and the air suspension system 100 is disposed on the vehicle body 200.
In the related art, the rubber suspension is always applied to the automobile industry with the cost advantage, but the damping of the rubber suspension is small, so that the rubber suspension cannot meet the requirements of damping performance under low and high frequencies.
In the embodiment of the present application, the air pressure supply device 40 can be controlled to input different amounts of air into the air pressure suspension 30 according to different vibration states of the driving device 20 at high frequency or low frequency, and the air can form internal circulation in the air pressure suspension 30 to generate different damping effects, so as to reduce the vibration of the driving device 20 to improve the comfort of the vehicle 1000.
When the driving device 20 is in a low-frequency vibration state, the air pressure supply device 40 is controlled to input a large amount of air into the air pressure suspension 30, the air forms an air internal circulation mode in the air pressure suspension 30, the low-frequency vibration of the driving device 20 can enable the air pressure suspension 30 to have characteristics of large rigidity and large damping, the air pressure suspension 30 can better resist large-amplitude displacement of the driving device 20, and meanwhile, the energy of vibration of the driving device 20 can be attenuated.
When the driving device 20 is in a high-frequency vibration state, the air pressure supply device 40 is controlled to input a small amount of air into the air pressure suspension 30, the air forms an air internal circulation mode in the air pressure suspension 30, the high-frequency vibration of the driving device 20 can enable the air pressure suspension 30 to have the characteristics of small rigidity and small damping, and the air pressure suspension 30 can realize better vibration isolation. The driving device 20 may include, but is not limited to, an engine, a decelerator, a controller, etc., among others.
In this way, no matter the driving device 20 vibrates at a high frequency or a low frequency, the pneumatic supply device 40 inputs air into the pneumatic suspension 30, the air can form an internal circulation in the pneumatic suspension 30, and the driving device 20 vibrates to enable the air to generate a damping effect in the pneumatic suspension 30, so that the vibration of the driving device 20 can be reduced, and the comfort of the vehicle 1000 can be improved. Compared to the rubber suspension in the related art, the pneumatic suspension 30 of the air suspension system 100 of the embodiment of the present application can satisfy the damping performance requirements at low and high frequencies.
In some embodiments, the pneumatic supply device 40 may be an air reservoir. The air suspension system 100 may also include air springs connected to the wheels of the vehicle 1000. The air pressure supply device 40 may input air into the air spring, and the pressure of the air in the air spring is increased with the increase of the amount of air charged, and the air spring may lift the vehicle body 200 to a certain height. When the air in the air spring is discharged to the atmosphere, the air pressure in the air spring is lowered, and thus the height of the vehicle body 200 is also lowered. Further, the air spring as an elastic member can also alleviate the impact load applied to the wheel from the road surface when the impact load is transmitted to the vehicle body 200 through the axle.
In this way, the air pressure supply device 40 can provide air to the air springs, and the air can circulate in the air springs to change the height of the vehicle body 200 of the vehicle 1000 and control the horizontal posture of the vehicle body 200, so that the stability and the comfort of the vehicle 1000 are ensured. The pneumatic pressure supply device 40 can supply air to the air spring to change the height of the vehicle body 200, and can also input air into the pneumatic suspension 30, and the air forms an internal circulation flow in the pneumatic suspension 30 to generate a damping effect, so that the vibration of the driving device 20 can be reduced. Thus, the utilization rate of the air pressure supply device 40 is greatly improved.
The vehicle body 200 is a base member of the vehicle 1000, and the vehicle body 200 may form a base appearance of the vehicle 1000. The vehicle body 200 may also be formed with a passenger compartment or the like of the vehicle 1000. It is understood that the driving device 20 in the operating state is a vibration source inherent in the vehicle 1000, and the driving device 20 is also disturbed by various vibrations from the outside, for example, the driving device 20 vibrates when the vehicle 1000 passes over a bumpy road. In the embodiment of the present application, the pneumatic suspension 30 is used to reduce the vibration of the driving device 20, so that not only can damage to parts of the vehicle body 200 caused by the vibration be avoided, but also the riding experience of passengers in the passenger compartment can be improved.
It should be noted that the pneumatic mount 30 of the present embodiment may be manufactured, used, sold, etc. as a separate component.
Referring to fig. 2, 4, 5 and 6, in some embodiments, the pneumatic suspension 30 includes a housing 31, a mounting member 32 connected to the housing 31, and an air bag 33 connected to the mounting member 32, wherein the housing 31 is fixed to the frame 10. Thus, the housing 31 can protect the attachment 32 and the airbag 33, and prevent the attachment 32 and the airbag 33 from being damaged.
Specifically, the housing 31 may be made of a metal material, the housing 31 may be a circular ring having a certain height, the housing 31 is disposed around the mounting member 32, the mounting member 32 is formed with a gap, and the air bag 33 is disposed in the gap of the mounting member 32. When the driving device 20 is in the vibration state, the air pressure supply device 40 is controlled to input air to the air bag 33 of the air pressure suspension 30, and the air forms an air internal circulation mode in the air bag 33. The air bag 33 is in an expanded state, so that the air bag 33 can effectively fill the gap of the mounting part 32, and the mounting part 32 and the air bag 33 work together to enable the air pressure to generate a damping effect along with the vibration change, so that the vibration of the driving device 20 can be improved, and the stability of the vehicle 1000 is improved.
Referring to fig. 4-6, in some embodiments, the mounting member 32 includes a first mounting member 321 and a second mounting member 322, the first mounting member 321 is disposed around the second mounting member 322, and the air bag 33 is disposed between the first mounting member 321 and the second mounting member 322.
In this way, when the driving device 20 is in the vibration state, as the air bag 33 is inflated by the air pressure supply device 40, the air bag 33 in the inflated state can effectively fill the gap between the first mounting part 321 and the second mounting part 322, and the first mounting part 321, the air bag 33 and the second mounting part 322 can generate the damping effect to damp the energy of the vibration of the driving device 20, so as to improve the vibration, the noise and the like of the driving device 20.
Specifically, the first mounting member 321 and the second mounting member 322 may be made of rubber. The first and second mounting elements 321, 322 may each be a circular ring having a height, and the diameter of the second mounting element 322 is smaller than the diameter of the first mounting element 321.
When the driving device 20 is in the low-frequency vibration state, the air pressure supply device 40 is controlled to input a large amount of air into the air bag 33 of the air pressure suspension 30, so that the air bag 33 is in a high-pressure inflated state, and thus the gap between the first mounting member 321 and the second mounting member 322 can be effectively filled. When the driving device 20 is in the high-frequency vibration state, the air pressure supply device 40 is controlled to input a small amount of air into the air bag 33 of the air pressure suspension 30, so that the air bag 33 is in the low-pressure inflation state, and a slight gap is formed between the first mounting part 321 and the second mounting part 322. When the driving device 20 is in the variable frequency vibration state, the air pressure supply device 40 is controlled to input air to the air bag 33, and the air bag 33 can fill the gap between the first mounting member 321 and the second mounting member 322 in the pressing state of the air bag 33 on the first mounting member 321 and the second mounting member 322.
Thus, when the driving device 20 is in the vibration state, the air pressure supply device 40 inputs air into the air bag 33, and the first mounting member 321, the air bag 33 and the second mounting member 322 generate damping effect to damp the energy of the vibration of the driving device 20, so as to improve the vibration and noise of the driving device 20.
Referring to fig. 4 and 7, in some embodiments, the air suspension system 100 includes a tube assembly 50 connected to the air pressure supply device 40, and the tube assembly 50 is connected to the air bag 33. In this manner, the gas in the gas pressure supply device 40 can be delivered into the airbag 33 through the tube assembly 50.
Specifically, an air inlet is provided on the airbag 33, the tube assembly 50 can communicate the air pressure supply device 40 with the air inlet, and the air of the air pressure supply device 40 can enter the airbag 33 through the tube assembly 50 and the air inlet. It can be understood that the air bag 33 may further include an air outlet, and the air inside the air bag 33 may be exhausted to the atmosphere through the air outlet, so as to prevent the air bag 33 from exploding due to a large amount of air stored in the air bag 33.
Referring to fig. 4-6, in some embodiments, the pneumatic suspension 30 further includes an annular channel 34 connected to the air bag 33, the annular channel 34 being connected to the second mounting member 322. In this way, the air pressure supply device 40 ensures that the air can flow into the air bag 33 by supplying air into the annular passage 34 to perform flow circulation in the air bag 33.
In some embodiments, the tube assembly 50 of the pneumatic suspension 30 may be used to connect the pneumatic supply device 40 and the annular channel 34, the pneumatic supply device 40 delivering gas to the annular channel 34, the gas being flowable into the bladder 33 for flow circulation within the bladder 33.
In one example, the housing 31, the first mounting element 321 and the second mounting element 322 are all circular rings with a certain height, the diameter of the housing 31 is larger than that of the first mounting element 321, the diameter of the first mounting element 321 is larger than that of the second mounting element 322, the housing 31 is arranged around the first mounting element 321, the first mounting element 321 is arranged around the second mounting element 322, and the air bag 33 is clamped between the first mounting element 321 and the second mounting element 322. The number of the annular channels 34 may be two, two annular channels 34 are respectively disposed at both ends of the second mounting part 322 in a direction perpendicular to the radial direction of the second mounting part 322, and both the two annular channels 34 are communicated with the air bag 33, and the annular channels 34 are located between the air bag 33 and the second mounting part 322. In particular, the annular channel 34 may be made of a metallic material. The annular channel 34 is located between the bladder 33 and the second mounting member 322.
In this case, the gas pressure supply device 40 is controlled to supply gas to the annular passage 34, the gas can flow into the airbag 33, and the gas forms an internal gas circulation pattern in the airbag 33. The air-bag 33 in its inflated condition may effectively fill the gap between the first mounting element 321 and the second mounting element 322. When the driving device 20 is in a vibration state, the annular flow passage, the first mounting part 321, the second mounting part 322 and the air bag 33 work together to enable the air pressure to generate a damping effect along with the vibration change, so that the vibration of the driving device 20 can be reduced to improve the stability and comfort of the vehicle 1000.
Referring again to fig. 4-6, in some embodiments, the number of air bags 33 is multiple, and the multiple air bags 33 are arranged at intervals along the circumference of the annular channel 34. As such, as the air pressure supply device 40 inflates the air cells 33, the plurality of air cells 33 can more effectively fill the gap between the first and second mounting members 321 and 322.
Specifically, the air bag 33 may have a cylindrical shape. The number of the plurality of air cells 33 may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc., which are not listed here. It should be noted that, any two adjacent air cells 33 are communicated, and when the air pressure supply device 40 supplies air to any one of the air cells 33, the air can be circulated in the plurality of air cells 33.
For example, when the number of the air bags 33 is 2, the included angle between the 2 air bags 33 and the 2 connecting lines of the axle center of the second mounting member 322 is 180 °. When the number of the air bags 33 is 3, the included angle between the adjacent 2 air bags 33 and the axial center 2 connecting line of the second mounting part 322 is 120 degrees. When the number of the air bags 33 is 4, the included angle between the adjacent 2 air bags 33 and the axial center 2 connecting line of the second mounting part 322 is 90 degrees.
