According to different road conditions and the signal from the distance sensor, the on-board computer will determine the change in the ground clearance of the vehicle, and then control the compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the ground clearance of the chassis vehicle to increase the stability of the vehicle at high speeds or the passability in complex road conditions.

[0003] In the related art, the air suspension compresses the air in the environment into the air suspension through a compressor to control the ground clearance of the vehicle, which consumes a large amount of energy of the vehicle. Utility Model Content

[0004] The embodiments of the present application provide an air suspension and a vehicle, which can reduce the energy consumption of the vehicle.

[0005] In a first aspect, an embodiment of the present application provides an air suspension, which includes a supercharging device and a lifting device, wherein the supercharging device is used to provide high-pressure gas to the lifting device to drive the lifting device to rise or fall, and the lifting device is used to control the ground clearance of the vehicle; the supercharging device includes a turbocharger and a compressor, and the turbocharger includes an exhaust gas inlet, an exhaust gas exhaust port, a first air intake port and a first exhaust port, the exhaust gas inlet port is used to connect to the exhaust end of the engine to receive the exhaust gas of the engine, the exhaust gas exhaust port is connected to the outside atmosphere and is used to discharge the exhaust gas of the engine, the first air intake port is connected to the outside atmosphere to inhale air from the outside atmosphere, the turbocharger is configured to supercharge the air under the drive of the exhaust gas to form supercharged gas, and the first exhaust port is used to discharge the supercharged gas; the compressor has an adapter, a second air intake port and a second exhaust port, the adapter port is connected to the first exhaust port, the second air intake port is used to connect to the outside atmosphere, and the second exhaust port is used to connect to the lifting device.

[0006] Based on the air suspension of the embodiment of the present application, the exhaust gas exhausted by the engine when working enters the turbocharger through the exhaust gas inlet to drive the turbocharger to work and is discharged from the exhaust gas exhaust port. Negative pressure is formed in part of the internal space of the turbocharger and adsorbs air from the outside atmosphere through the first air intake port. After being turbocharged, the air forms supercharged gas and enters the compressor through the first exhaust port and the adapter. The compressor further pressurizes the supercharged gas and supplies it to the lifting device through the second exhaust port. In this way, the kinetic energy of the engine exhaust gas is used to perform preliminary compression on the supercharged gas, thereby reducing the working intensity and energy consumption of the compressor. In addition, the compressor can work alone (that is, the turbocharger is not working). When the compressor works alone, it draws air from the outside atmosphere through the second air intake port and pressurizes it, and then supplies it to the lifting device through the second exhaust port.

[0007] In some embodiments of the present application, the boosting device also includes a one-way valve, which is arranged between the first exhaust port and the transfer interface, and the one-way valve is configured to be turned on when the air pressure value at the first exhaust port is greater than the air pressure value at the transfer interface.

[0008] Based on the above embodiment, when the air pressure in the turbocharger is greater than the air pressure in the compressor, the one-way valve is turned on, and the turbocharger and the compressor compress the boost gas at the same time. When the air pressure in the turbocharger is less than the air pressure in the compressor, the one-way valve is blocked, thus realizing automatic on and off of the turbocharger and the compressor.

[0009] In some embodiments of the present application, the boosting device further includes a cooler, which is connected in series with the one-way valve, the cooler is connected to the first exhaust port, and the one-way valve is connected to the adapter.

[0010] Based on the above embodiment, when the turbocharger inhales outside air through the first air intake port and compresses it, the temperature of the outside air rises after absorbing the heat of the exhaust gas in the turbocharger. After the boosted gas is discharged from the turbocharger, it is cooled in the cooler so that the cooled boosted gas is close to the working temperature of the boosted gas in the lifting assembly, so as to avoid the deviation of the ground clearance adjustment of the vehicle due to the temperature drop of the boosted gas with excessively high temperature after entering the lifting device.

[0011] In some embodiments of the present application, the boosting device also includes an oil-gas separator, which is connected in series with the cooler and the one-way valve; the oil-gas separator is arranged between the cooler and the one-way valve, or the cooler is arranged between the oil-gas separator and the one-way valve.

[0012] Based on the above embodiment, when the turbocharger inhales external air through the first air intake port and compresses it, the external air will mix with the incompletely burned fuel in the exhaust gas into the pressurized gas after contacting the exhaust gas in the turbocharger. After the pressurized gas is discharged from the turbocharger, oil and gas separation is performed in the oil-gas separator.

[0013] In some embodiments of the present application, the lifting device includes a main pipe assembly and a plurality of airbag branch pipe assemblies, the main pipe assembly is connected to the second exhaust port, and can be connected to the second air intake port in an on-off manner, and the main pipe assembly can control the connection and disconnection of the lifting device with the outside atmosphere; the plurality of airbag branch pipe assemblies are all connected to the main pipe assembly, and the airbag branch pipe assembly is used to control the ground clearance of the vehicle.

[0014] Based on the above embodiment, the main pipe assembly is connected to the second exhaust port to receive the pressurized gas compressed by the turbocharger, and the pressurized gas in the main pipe assembly is distributed to multiple airbag branch pipe assemblies to achieve inflation of the multiple airbag branch pipe assemblies, and the main pipe assembly and the second air intake port can be connected and disconnected, and the pressurized gas in the lifting device can be discharged to the outside atmosphere after the main pipe assembly and the second air intake port, thereby achieving exhaust of the multiple airbag branch pipe assemblies.

[0015] In some embodiments of the present application, the main pipe assembly includes a main pipe and a main control valve, the main pipe is connected to the second exhaust port, and the airbag branch pipe assembly is connected to the main pipe; the two ports of the main control valve are respectively connected to the second exhaust port and the second air intake port.

[0016] Based on the above embodiment, the main pipe is connected to multiple airbag branch pipe assemblies to disperse the pressurized gas into the multiple airbag branch pipe assemblies. When the main control valve is turned on, the main pipe is connected to the second air intake port, and the pressurized gas in the multiple airbag branch pipe assemblies can be discharged into the outside atmosphere bypassing the compressor.

[0017] In some embodiments of the present application, the airbag branch pipe assembly includes an airbag and a first branch pipe valve connected in series, and the first branch pipe valve is connected to the main pipe to control the connection and disconnection between the airbag and the main pipe.

[0018] Based on the above embodiment, the first branch valve controls the connection between the airbag and the main pipe. When the first branch valve is turned on, pressurized gas is filled into the airbag or discharged into the airbag to adjust the ground clearance of the vehicle. When the first branch valve is blocked, the air pressure in the airbag is stable.

[0019] In some embodiments of the present application, the air suspension further includes an air tank branch pipe assembly, wherein the air tank branch pipe assembly includes an air tank and a second branch pipe valve connected in series, and the second branch pipe valve is connected to the main pipe.

[0020] Based on the above embodiment, the air tank is used to store pressurized gas. The pressurized gas generated by the turbocharger and the compressor can be first stored in the air tank. When the ground clearance of the vehicle needs to be adjusted, the second branch valve and the corresponding first branch valve conduct the pressurized gas in the air tank to fill the corresponding airbag. There is no need for a compressor to gradually compress the air, so that the air suspension can respond quickly according to the different ground clearances of the vehicle.

[0021] In some embodiments of the present application, the air pressure in the air storage tank is greater than or equal to 10 Bar and less than or equal to 15 Bar.

[0022] Based on the above embodiments, within this range, the pressurized gas in the gas tank has a higher gas pressure value, which can achieve faster adjustment of the ground clearance of the vehicle.

[0025] Based on the air suspension and vehicle of the embodiment of the present application, the exhaust gas exhausted by the engine when working enters the turbocharger through the exhaust gas inlet to drive the turbocharger to work and is discharged from the exhaust gas exhaust port.

In this way, the kinetic energy of the engine exhaust is used to perform preliminary compression on the supercharged gas, thereby reducing the working intensity and energy consumption of the compressor. In addition, the compressor can work alone (that is, the turbocharger is not working). When the compressor works alone, it draws air from the outside atmosphere through the second air intake port and pressurizes it, and then supplies it to the lifting device through the second exhaust port.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Air suspension is a system that adjusts the ground clearance of the vehicle. According to different road conditions and the signal from the distance sensor, the on-board computer will determine the change in the ground clearance of the vehicle, and then control the compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the ground clearance of the chassis vehicle to increase the stability of the vehicle at high speeds or the passability in complex road conditions.

[0031] In the related art, air suspension uses a compressor to compress the air in the environment into the air suspension to control the ground clearance of the vehicle, which requires consuming a large amount of energy of the vehicle.

[0032] To solve the above technical problems, please refer to Figure 1 As shown, in the first aspect, an embodiment of the present application provides an air suspension which can reduce the energy consumption of a vehicle.

[0033] Please refer to Figure 1As shown, the air suspension includes a supercharger 10 and a lifting device 20. The supercharger 10 is used to provide high-pressure gas to the lifting device 20 to drive the lifting device 20 to rise or fall. The lifting device 20 is used to control the ground clearance of the vehicle; the supercharger 10 includes a turbocharger 11 and a compressor 12. The turbocharger 11 includes an exhaust gas inlet V1, an exhaust gas outlet V2, a first air intake port V3 and a first exhaust port V4. The exhaust gas inlet V1 is used to connect to the exhaust end of the engine to receive the exhaust gas of the engine. The exhaust gas outlet V2 is used to connect to the exhaust end of the engine to receive the exhaust gas of the engine. The air port V2 is connected to the outside atmosphere and is used to discharge the exhaust gas of the engine. The first air intake port V3 is connected to the outside atmosphere to inhale air from the outside atmosphere. The turbocharger 11 is configured to pressurize the air under the drive of the exhaust gas to form a pressurized gas. The first exhaust port V4 is used to discharge the pressurized gas; the compressor 12 has an adapter port V5, a second air intake port V6 and a second exhaust port V7. The adapter port V5 is connected to the first exhaust port V4, the second air intake port V6 is used to connect to the outside atmosphere, and the second exhaust port V7 is used to connect to the lifting device 20.

[0034] The ground clearance of a vehicle in this application refers to the distance between the ground and the rigid object at the bottom of the vehicle.

[0035] The turbocharger 11 uses the inertial impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. It can be understood that the turbocharger 11 includes a housing, a rotating shaft, a turbine and an impeller. The housing has an exhaust gas inlet V1, an exhaust gas exhaust port V2, a first air intake port V3, a first exhaust port V4, an exhaust gas chamber and a pressurization chamber. The exhaust gas chamber is connected to the exhaust gas inlet V1 and the exhaust gas exhaust port V2, and the pressurization chamber is connected to the first air intake port V3 and the first exhaust port V4. The turbine is in the exhaust gas chamber, and the impeller is in the pressurization chamber. The turbine and the impeller are coaxially fixed to the rotating shaft. The exhaust gas of the engine drives the turbine to rotate, and the turbine drives the impeller to rotate through the transmission shaft. The impeller forms a negative pressure in the pressurization chamber to extract air from the outside atmosphere. The pressure of the pressurized gas generated in the pressurization chamber in the embodiment of the present application can reach 3Bar.

[0036] The compressor 12 is used to boost low-pressure gas to high-pressure gas. In the embodiment of the present application, the compressor 12 is driven by an electric motor.

[0037] Based on the air suspension of the embodiment of the present application, the exhaust gas discharged when the engine is working enters the turbocharger 11 through the exhaust gas inlet V1 to drive the turbocharger 11 to work and is discharged from the exhaust gas exhaust port V2. Negative pressure is formed in part of the internal space of the turbocharger 11 and absorbs air from the outside atmosphere through the first air intake port V3. After being turbocharged, the air forms supercharged gas and enters the compressor 12 through the first exhaust port V4 and the adapter V5. The compressor 12 further pressurizes the supercharged gas and supplies it to the lifting device 20 through the second exhaust port V7. In this way, the kinetic energy of the engine exhaust gas is used to perform preliminary compression on the supercharged gas, thereby reducing the working intensity and energy consumption of the compressor 12. In addition, the compressor 12 can work alone (that is, the turbocharger 11 is not working). When the compressor 12 works alone, it draws air from the outside atmosphere through the second air intake port V6 and pressurizes it, and then supplies it to the lifting device 20 through the second exhaust port V7.

[0038] Please refer to Figure 1 As shown, in some embodiments of the present application, the boosting device 10 also includes a one-way valve 13, which is arranged between the first exhaust port V4 and the transfer port V5, and the one-way valve 13 is configured to be turned on when the air pressure value at the first exhaust port V4 is greater than the air pressure value at the transfer port V5.

[0039] The one-way valve 13 is also called a non-return valve or a check valve, and is used to prevent the reverse flow of liquid in a hydraulic system or the reverse flow of gas in a pneumatic system. In the embodiment of the present application, when the air pressure in the turbocharger 11 is greater than the air pressure in the compressor 12, the one-way valve 13 is turned on, and the turbocharger 11 and the compressor 12 compress the pressurized gas at the same time; when the air pressure in the turbocharger 11 is less than the air pressure in the compressor 12, the one-way valve 13 is blocked, thereby realizing automatic switching of the turbocharger 11 and the compressor 12.

[0040] Please refer to Figure 1 As shown, in some embodiments of the present application, the boost device 10 further includes a cooler 14, which is connected in series with the one-way valve 13, the cooler 14 is connected to the first exhaust port V4, and the one-way valve 13 is connected to the transfer port V5.

[0041] The cooler 14 is used to reduce the temperature of the pressurized gas. The cooler 14 in the embodiment of the present application can be an air-cooled cooler or a liquid-cooled cooler, wherein the liquid-cooled cooler can be a tube-in-tube cooler or a plate cooler. In the embodiment of the present application, a convection plate cooler is specifically used, and the cooling medium is cooling water.

[0042] When the turbocharger 11 inhales outside air through the first air intake port V3 and compresses it, the temperature of the outside air will rise to 160° to 200°C after absorbing the heat of the exhaust gas in the turbocharger 11. After the boosted gas enters the cooler 14, the temperature can be reduced to 50° to 80°. It can be understood that the lower the temperature of the gas, the easier it is to compress the gas. In this way, it is convenient to compress the boosted gas after the temperature of the boosted gas is reduced. In addition, the boosted gas after cooling is close to the working temperature of the boosted gas in the lifting device 20, so as to avoid the boosted gas with too high a temperature from entering the lifting device 20 and causing the temperature to drop, resulting in a deviation in the ground clearance adjustment of the vehicle.

[0043] Please refer to Figure 1 As shown, in some embodiments of the present application, the boosting device 10 also includes an oil-gas separator 15, which is connected in series with the cooler 14 and the one-way valve 13; the oil-gas separator 15 is arranged between the cooler 14 and the one-way valve 13, or the cooler 14 is arranged between the oil-gas separator 15 and the one-way valve 13. It can be understood that when the oil-gas separator 15 is arranged between the cooler 14 and the one-way valve 13, the cooler 14 is connected to the turbocharger 11, and the one-way valve 13 is connected to the lifting device 20; when the cooler 14 is arranged between the oil-gas separator 15 and the one-way valve 13, the oil-gas separator 15 is connected to the turbocharger 11, and the one-way valve 13 is connected to the lifting device 20.

[0044] The oil-gas separator 15 is a device for separating liquid oil from the pressurized gas. When the turbocharger 11 inhales outside air through the first air inlet V3 and compresses it, the outside air will mix with the fuel in the pressurized gas after contacting the exhaust gas in the turbocharger 11. After the pressurized gas is discharged from the turbocharger 11, the oil and gas are separated in the oil-gas separator 15. The type, size, etc. of the oil-gas separator 15 are not limited in the embodiment of the present application.

[0045] Please refer to Figure 1 As shown, in some embodiments of the present application, the lifting device 20 includes a main pipe assembly 21 and a plurality of airbag branch pipe assemblies 22. The main pipe assembly 21 is connected to the second exhaust port V7 and can be connected to the second air intake port V6. The main pipe assembly 21 can control the connection between the lifting device 20 and the outside atmosphere; the plurality of airbag branch pipe assemblies 22 are all connected to the main pipe assembly 21, and the airbag branch pipe assembly 22 is used to control the ground clearance of the vehicle.

[0046] The main pipe assembly 21 is connected to the second exhaust port V7 to receive the pressurized gas compressed by the turbocharger 11. The pressurized gas in the main pipe assembly 21 is distributed to multiple airbag branch pipe assemblies 22, so that the multiple airbag branch pipe assemblies 22 can be inflated, and the main pipe assembly 21 and the second air intake port V6 can be connected and disconnected. After the main pipe assembly 21 and the second air intake port V6 are connected, the pressurized gas in the lifting device 20 can be discharged to the outside atmosphere, so that the multiple airbag branch pipe assemblies 22 can be exhausted.

[0047] In some embodiments of the present application, the main pipe assembly 21 includes a main pipe 211 and a main control valve 212, the main pipe 211 is connected to the second exhaust port V7, and the airbag branch pipe assembly 22 and the main pipe 211 can be connected and disconnected; the two ports of the main control valve 212 are respectively connected to the second exhaust port V7 and the second air intake port V6.

[0048] The main pipe 211 is used to connect the compressor 12 and the plurality of airbag branch pipe assemblies 22. The main pipe 211 in the embodiment of the present application is configured as a soft pipe to facilitate the arrangement of the main pipe 211 in the vehicle body. The master control valve 212 is used to control the on-off of the main pipe 211 and the second air intake port V6, that is, to control the connection between the main pipe 211 and the outside atmosphere. In some embodiments of the present application, the master control valve 212 is configured as an electronic valve, and the air suspension further includes a control module. The master control valve 212 is electrically connected to the control module, and the on-off of the master control valve 212 is controlled by the control module. The control module in the embodiment of the present application may be an onboard computer.

[0049] The main pipe 211 is connected to multiple airbag branch pipe assemblies 22 to disperse the pressurized gas into the multiple airbag branch pipe assemblies 22. When the main control valve 212 is turned on, the main pipe 211 is connected to the second air intake port V6, and the pressurized gas in the multiple airbag branch pipe assemblies 22 can be discharged into the outside atmosphere bypassing the compressor 12.

[0050] Please refer to Figure 1 As shown, in some embodiments of the present application, the airbag branch pipe assembly 22 includes an airbag 221 and a first branch pipe valve 222 connected in series. The first branch pipe valve 222 is connected to the main pipe 211 to control the connection and disconnection of the airbag 221 and the main pipe 211. The first branch pipe valve 222 controls the connection between the airbag 221 and the main pipe 211. When the first branch pipe valve 222 is turned on, the pressurized gas is filled into the airbag 221 or discharged out of the airbag 221 to adjust the ground clearance of the vehicle. When the first branch pipe valve 222 is blocked, the air pressure in the airbag 221 is stable.

[0051] The first branch pipe valve 222 is used to control the on-off of the airbag 221 and the main pipe 211. In some embodiments of the present application, the first branch pipe valve 222 can be configured as an electrically controlled valve and electrically connected to the above-mentioned control module.

[0052] The airbag 221 is used to control the distance between the vehicle body and the ground. It is understandable that the more pressurized gas in the airbag 221, the farther the vehicle body is from the ground, and the amount of pressurized gas in each airbag 221 is controlled by the corresponding first branch pipe valve 222. In some embodiments of the present application, the number of airbag branch pipe assemblies 22 is four, and the four airbags 221 correspond to the four wheels of the vehicle.

[0053] Please refer to Figure 1 As shown, in some embodiments of the present application, the air suspension further includes an air tank branch pipe assembly 23 , which includes an air tank 231 and a second branch pipe valve 232 connected in series, and the second branch pipe valve 232 is connected to the main pipe 211 .

[0054] The gas tank 231 is used to store pressurized gas. The pressurized gas generated by the turbocharger 11 and the compressor 12 can be first stored in the gas tank 231. When the ground clearance of the vehicle needs to be adjusted, the second branch valve 232 and the corresponding first branch valve 222 conduct the pressurized gas in the gas tank 231 to fill the corresponding airbag 221. There is no need for the compressor 12 to gradually compress the air so that the air suspension can respond quickly according to the different ground clearances of the vehicle. In the embodiment of the present application, the shape, material, and size of the gas tank 231 are not limited, as long as the gas tank 231 can store enough gas. It can be understood that the volume of the gas tank 231 is equal to the maximum volume of gas that can be contained in multiple airbags 221.

[0055] The second branch pipe valve 232 is used to control the on-off of the gas storage tank 231 and the main pipe 211. In some embodiments of the present application, the second branch pipe valve 232 can be configured as an electrically controlled valve and electrically connected to the above-mentioned control module.

[0056] In some embodiments of the present application, the air pressure value in the air tank 231 is greater than or equal to 10Bar and less than or equal to 15Bar, for example, 11Bar, 12Bar, 13Bar, 14Bar, etc. In this way, the air tank 231 has a sufficient air pressure value to achieve a faster response to the ground clearance of the vehicle. It can be understood that the heavier the vehicle body, the higher the air pressure value in the air tank 231 should be. Therefore, the pressure value in the air tank 231 can be set according to the weight of the vehicle. In addition, the pressure value of the compressor 12 should be greater than or equal to the air pressure value of the pressurized gas in the air tank 231, and the pressure value of the compressor 12 can be set according to the air pressure value in the air tank 231.

[0057] In a second aspect, an embodiment of the present application provides a vehicle, the vehicle comprising an engine and the above air suspension. It is understood that the above airbags 221 are located between the vehicle body and the wheels, and the number of airbags 221 is set corresponding to the number of wheels, and each airbag 221 is responsible for controlling the corresponding wheel.

[0058] Based on the vehicle in the embodiment of the present application, the vehicle can be more energy-efficient due to the above-mentioned air suspension.
