Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
In a first aspect, as shown in FIG. 1, an embodiment of the present application provides an air suspension system 100. The air suspension system 100 includes an air circuit 110, a vent valve 120, and a support device 130. A vent valve 120 is connected to the gas circuit 110. The supporting device 130 is connected to the air path 110, and the supporting device 130 is used for supporting the chassis of the vehicle. Wherein the vent valve 120 includes a receiving chamber 122, and the vent valve 120 opens the air passage 110 when the liquid level in the receiving chamber 122 is less than a height threshold. When the liquid level in the accommodating chamber 122 is greater than or equal to the height threshold, the vent valve 120 is blocked unidirectionally along the air intake direction of the air path 110.
The air suspension system 100 includes an air passage 110, a vent valve 120 and a support device 130 respectively connected to the air passage, the support device 130 for supporting a chassis of the vehicle. Specifically, ambient air can enter the air passage 110 via the vent valve 120 and flow into the support device 130 through the air passage 110. The amount of gas within the support device 130 increases such that the support device 130 can be extended, thereby increasing the distance between the chassis of the vehicle and the ground. Likewise, the gas within the support device 130 is able to flow out of the air suspension system 100 via the gas circuit 110 and the vent valve 120, and the amount of gas within the support device 130 is reduced, such that the support device 130 is able to collapse, thereby reducing the distance between the chassis and the ground. By controlling the amount of the gas in the supporting device 130, the distance between the chassis and the ground can be controlled, so that the vehicle can meet the driving requirements of different road conditions, and the service performance of the vehicle is improved.
In some examples, different gas contents in the supporting device 130 can be controlled according to different road conditions of the vehicle, so that the distance between the chassis of the vehicle and the ground can be matched with the road conditions, and the service performance of the vehicle is further improved.
It can be appreciated that the supporting device 130 may include a control valve, and the control valve controls the on/off between the supporting device 130 and the air path 110, so as to avoid the leakage of air in the supporting device 130, thereby further improving the reliability of the air suspension system 100.
In some examples, the gas flowing into the support 130 may be air, an inert gas mixture, or the like.
In some examples, the support device 130 may be an air spring.
In some examples, the number of vent valves 120 may be one or more. The number of vent valves 120 may be the same as or different from the number of air passages 110.
The vent valve 120 includes a receiving chamber 122, and it is understood that the receiving chamber 122 includes a receiving chamber opening through which gas can enter the gas circuit 110.
It will be appreciated that when the vehicle wades shallowly, the liquid level in the accommodating chamber 122 is less than the height threshold, at this time, water is not easy to flow into the air passage 110 through the air vent valve 120, so that the air vent valve 120 is set to be conductive, so that air can enter the air passage 110 through the air vent valve 120, and air in the air passage 110 can be discharged through the air vent valve 120, thereby ensuring normal operation of the air suspension system 100.
When the vehicle wades deeper, the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold value, the ventilation valve 120 is blocked unidirectionally along the air inlet direction of the air channel 110, so that water cannot flow into the air channel 110 through the ventilation valve 120, the water is prevented from flowing into the air channel 110 and the supporting device 130, the normal operation of the air suspension system 100 is prevented from being influenced, and the use reliability of the air suspension system 100 is further ensured.
It will be appreciated that the direction of the inlet of the air path 110 is the direction of the air flow into the air path 110, i.e. along the direction of the vent valve 120 to the air path 110.
Meanwhile, when the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold, the ventilation valve 120 is set to be blocked unidirectionally along the air inlet direction of the air channel 110, so that air in the air channel 110 can still be discharged through the ventilation valve 120, and when the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold, the distance between the chassis and the ground can still be controlled to be reduced, and the use flexibility of the air suspension system 100 is improved. Meanwhile, the excessive pressure of the air in the air suspension system 100 can be avoided, so that the air in the air suspension system 100 can be discharged in time, and the use safety of the air suspension system 100 is ensured.
In some examples, different height thresholds may be set for different vehicles, improving the applicability of air suspension system 100.
In some examples, as shown in fig. 1, the vent valve 120 further includes a float 124 and a vent hole 126. A float ball 124 is disposed within the receiving chamber 122. The vent hole 126 is connected to the air passage 110, and the float ball 124 can be close to or far from the vent hole 126.
A float ball 124 is provided in the accommodating chamber 122, and it is understood that the float ball 124 can float in the accommodating chamber 122 when water flows into the accommodating chamber 122.
In some examples, the float ball 124 may be plastic or foam. In some examples, the float ball 124 may be a hollow ball, further reducing the mass of the float ball 124, ensuring that the float ball 124 floats within the receiving cavity 122.
The vent hole 126 is connected to the air passage 110, and it is understood that the vent hole 126 has a shape matching that of the float ball 124. Specifically, when the liquid level in the accommodating chamber 122 increases, the float ball 124 increases with the increase of the liquid level under the action of the buoyancy force, thereby approaching the vent hole 126. When the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold, the floating ball 124 seals the vent hole 126, so that the vent valve 120 can be blocked unidirectionally along the air inlet direction of the air channel 110, and water is prevented from entering the air channel 110 and the supporting device 130. When the liquid level in the receiving chamber 122 drops, the float ball 124 can be separated from the vent hole 126 so that the vent valve 120 can be conducted.
In some examples, the vent hole 126 may be surrounded by a rubber material, which further improves the sealing effect of the float ball 124 on the vent hole 126. In some examples, the vent 126 is spherical, ensuring tightness of the float ball 124 to the vent 126.
In some examples, the vent 126 is disposed above the receiving cavity opening, preventing water from flowing directly into the vent 126 via the receiving cavity opening.
Specifically, when the float ball 124 seals the vent hole 126, if the gas in the gas path 110 needs to be exhausted, the gas in the gas path 110 can be controlled to impact the float ball 124, so that the float ball 124 and the vent hole 126 are separated from each other under the impact of the gas, and the gas can be exhausted from the gas path 110 through the vent hole 126. In addition, when the gas in the gas path 110 is exhausted, because the flow rate of the gas is high, even if the floating ball 124 and the vent hole 126 are separated from each other, the water in the accommodating cavity 122 cannot enter the gas path 110 through the vent hole 126 under the impact action of the gas, so that the use reliability of the air suspension system 100 is further ensured.
When the exhaust is completed, the air in the air circuit 110 can be controlled to stop impacting the floating ball 124, the floating ball 124 can block the vent hole 126 again under the action of the floating force, the air is prevented from flowing into the air circuit 110, other operations are not needed, the automation performance of the air suspension system 100 is improved, and the use reliability of the air suspension system 100 is ensured.
Through setting up floater 124 to when the liquid level height in holding chamber 122 is greater than or equal to the high threshold value, floater 124 can automatic shutoff air vent 126, and when the liquid level height in holding chamber 122 falls to be less than the high threshold value, floater 124 is automatic to be kept away from air vent 126, has improved the automation performance of air suspension system 100, has ensured the stability in use of air suspension system 100.
In some examples, as shown in fig. 1, air suspension system 100 further includes a drive device 140. The driving device 140 is disposed on the gas path 110. The driving device 140 is connected with the ventilation valve 120, and the driving device 140 is used for driving gas to enter the gas path 110 through the ventilation valve 120; or the driving device 140 is used for driving the gas in the gas path 110 to be discharged through the vent valve 120.
In some examples, the driving device 140 may be an air pump. It will be appreciated that the number of drive devices 140 may be one or more.
The driving device 140 is disposed on the air path 110 and connected with the air vent valve 120, so that the driving device 140 can drive external air to enter the air path 110 through the air vent valve 120, and can also drive air in the air path 110 to be discharged through the air vent valve 120, thereby promoting the flow of air, shortening the time required for the air to flow into the air path 110 and flow out through the air path 110, enabling the supporting device 130 to be rapidly stretched or contracted, and further improving the service performance of the air suspension system 100.
In some examples, different rotational speeds of the drive device 140 may be controlled to control the flow rate of gas into the gas circuit 110, or the flow rate of gas out of the gas circuit 110, further improving the flexibility of use of the air suspension system 100.
In some examples, when the floating ball 124 seals the vent hole 126 and the gas in the gas circuit 110 needs to be exhausted, the driving device 140 may also drive the gas in the gas circuit 110 to flow, impact the floating ball 124, and thus achieve the exhaust effect.
In some examples, as shown in fig. 1, air suspension system 100 further includes a sensor 150 and a control 160. The sensor 150 is connected to the vent valve 120, and the sensor 150 is used to obtain the conductive state of the vent valve 120. The control device 160 is connected to the sensor 150 and the driving device 140, and the control device 160 is used for controlling the driving device 140 to start or stop according to the conducting state of the ventilation valve 120.
The air suspension system 100 includes a sensor 150, it being understood that the sensor 150 is electrically connected to the vent valve 120. In some examples, the sensor 150 may be electrically connected to the vent valve 120 by a wired means, and the sensor 150 may also be electrically connected to the vent valve 120 by a wireless means.
It will be appreciated that the control device 160 is electrically connected to the sensor 150 and the drive device 140, and in some examples, the control device 160 may be electrically connected to the sensor 150 and the drive device 140 by wires, and the control device 160 may also be electrically connected to the sensor 150 and the drive device 140 by wireless.
Specifically, when the vent valve 120 is turned on, the control device 160 may control the driving device 140 to work, drive the external air into the air path 110, or drive the air in the air path 110 to be exhausted, so as to ensure that the air suspension system 100 can work normally.
When the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold, the control device 160 can control the driving device 140 to stop working when the ventilation valve 120 is cut off unidirectionally along the air inlet direction of the air channel 110, so that the driving device 140 can be prevented from driving air to enter the ventilation valve 120 when the ventilation valve 120 is cut off unidirectionally along the air inlet direction of the air channel 110, and the driving device 140 idles, so that energy is wasted and even the driving device 140 is damaged.
In addition, when the liquid level in the accommodating cavity 122 is greater than or equal to the height threshold, the ventilation valve 120 is blocked unidirectionally along the air inlet direction of the air path 110, the control device 160 can also control the driving device 140 to drive the air in the air path 110 to be discharged, so that the air in the air path 110 can impact the floating ball 124 and be discharged through the ventilation hole 126, thereby improving the use flexibility of the air suspension system 100.
By providing the sensor 150 and the control device 160, the control device 160 can be started or stopped according to the conduction state of the vent valve 120, so that the damage of the driving device 140 is avoided, the service life of the driving device 140 is prolonged, the waste of energy is reduced, and the use reliability of the air suspension system 100 is further improved.
In some examples, the sensor 150 may be a displacement sensor, through which the displacement of the float ball 124 is obtained, thereby determining the conductive state of the vent valve 120, and improving the accuracy of the obtained conductive state of the vent valve 120.
In some examples, as shown in fig. 1, air suspension system 100 further includes an acoustic panel 170. The baffle 170 encloses a baffle cavity 172. The vent valve 120 and/or the drive device 140 are disposed within the sound-deadening chamber 172.

The baffle 170 encloses and defines a sound-deadening chamber 172, and the vent valve 120 and/or the driver 140 are disposed within the sound-deadening chamber 172 such that the baffle 170 absorbs noise generated by the intake or exhaust of the vent valve 120 and/or noise generated by the operation of the driver 140, avoiding transmission of noise to the cab or other location, reducing noise from the air suspension system 100, and further improving the performance of the air suspension system 100.

In some examples, the vehicle may be a work vehicle or a commercial vehicle, or the like.
In one particular embodiment, as shown in FIG. 1, an embodiment of the present application provides an air suspension system 100. The air suspension system 100 includes an air circuit 110, an air vent valve 120, a support device 130, and a drive device 140. Specifically, the vent valve 120 may be a ball float valve, the support device 130 may be an air spring, and the driving device 140 may be an air pump.
Specifically, the driving device 140 drives the external gas into the gas path 110 through the vent valve 120, or drives the gas in the gas path 110 to be discharged through the vent valve 120. The vent valve 120 includes a receiving chamber 122, a float 124, and a vent hole 126. It will be appreciated that the float 124 is a hollow foam material.
When the vehicle wades shallower, the liquid level in the receiving chamber 122 is lower such that the float ball 124 is separated from the vent hole 126, and gas can enter the gas path 110 via the vent valve 120 or be discharged from the gas path 110 via the vent valve 120.
When the vehicle wades deeper, the liquid level in the receiving chamber 122 is higher. When the liquid level in the accommodating cavity 122 is greater than the height threshold, the floating ball 124 can seal the vent hole 126 under the action of the floating force, so that water is prevented from entering the air passage 110 through the vent hole 126, and the use reliability of the air suspension system 100 is ensured.
In some examples, the vent valve 120 may be disposed at an upper portion of the wheel cover inner panel of the vehicle such that the vent valve 120 is further from the ground, further avoiding water from entering the air passage 110 via the vent valve 120.

It will be appreciated that when the float ball 124 seals the vent hole 126, if the gas needs to be exhausted through the vent valve 120, the driving device 140 may be controlled to be started to drive the gas in the gas path 110 to impact the float ball 124, so that the float ball 124 and the vent hole 126 are separated from each other under the impact of the gas, and the gas in the gas path 110 can be exhausted through the vent hole 126.
Air suspension system 100 also includes a sensor 150 and a control 160. Specifically, the sensor 150 is electrically connected to the vent valve 120 via a wire harness, and the control device 160 is electrically connected to the sensor 150 and the driving device 140 via a wire harness.
Specifically, the sensor 150 is a displacement sensor, and can obtain the conduction state of the vent valve 120 according to the displacement of the float ball 124. The control device 160 controls the driving device 140 to start or stop according to the conducting state of the vent valve 120, so as to avoid that when the vent valve 120 is cut off unidirectionally along the air inlet direction of the air path 110, the driving device 140 drives air to enter the vent valve 120, so that the driving device 140 idles, energy is wasted, and even the driving device 140 is damaged.
The air suspension system 100 further includes a baffle 170, the baffle 170 surrounding and defining a baffle cavity 172, the driving device 140 and the vent valve 120 being disposed within the baffle cavity 172 such that the baffle 170 is capable of absorbing noise generated by the driving device 140 and the vent valve 120, thereby reducing noise generated by the air suspension system 100 and improving the performance of the air suspension system 100.
It will be appreciated that the sound dampening chamber 172 includes an opening through which ambient air may enter the sound dampening chamber 172 and that air within the sound dampening chamber 172 may also be vented through the opening to improve the reliability of the air suspension system 100 in use.
