Preferably, a two-position three-way solenoid valve is used, for example a second two-position three-way solenoid valve 5 of the same type as the first two-position three-way solenoid valve 9. Of course, it will be appreciated that the two may be two-position, three-way solenoid valves of different types. The second two-position three-way solenoid valve 5 is connected to a main air pipe 6.
Specifically, the third interface I/O of the second two-position three-way solenoid valve 5 is directly connected to the gas outlet of the gas storage cylinder 4 through a pipeline, the first interface I of the second two-position three-way solenoid valve 5 is communicated with the first interface I of the first two-position three-way solenoid valve 9 through a pipeline, and the second interface O of the second two-position three-way solenoid valve 5 is detachably connected with the auxiliary gas pipeline 7, i.e., the auxiliary gas pipeline 7 can be detached from the second interface O of the second two-position three-way solenoid valve 5, so that the pipeline can be replaced or other pipelines or valves can be added conveniently. When the auxiliary air pipeline 7 is not in use, one end of the auxiliary air pipeline is connected to a second interface O of the second two-position three-way electromagnetic valve 5, and the whole pipeline can be fixed at other idle positions of the chassis or the vehicle bottom in a buckling mode and the like.

The difference between this embodiment and embodiment 1 is that a three-way check valve 12 is used in this embodiment instead of the second two-position three-way solenoid valve 5 in embodiment 1 to connect the air reservoir 4 and the air spring 11.
Specifically, referring to fig. 2, two of the ports of the three-way check valve 12 are in a normally open state, and a check valve is disposed in the third port. One of two interfaces that are always on communicates with first interface I of first two-position three way solenoid valve 9, and another interface that is always on passes through the tube coupling to the gas outlet of air receiver 4, and the third interface that is provided with the check valve is connected with the one end of supplementary gas pipeline 7, and the other end of supplementary gas pipeline 7 can be connected to on the tire 8.
Under the normal driving state of the vehicle, the air outlet of the air cylinder 4 and the first interface I of the first two-position three-way electromagnetic valve 9 are always in a communicated state through the three-way one-way valve 12, when the tire 8 needs to improve the tire pressure, the one-way valve in the third interface of the three-way one-way valve 12 is communicated, and then the air cylinder 4 and the tire 8 are communicated, so that the air cylinder 4 can supply air to the tire 8. Although the main air pipe 6 is also in the on state at this time, the air pressure in the air spring 11 is not affected due to the existence of the first two-position two-way electromagnetic valve 10.
In embodiments 1 and 2, when the internal air pressure of the air spring 11 is adjusted, the compressed air in the air spring 11 is directly discharged to the atmosphere through the valve.
Example 3

In the present embodiment, the connection with the auxiliary air-using component is realized by using the three-way check valve 12, as in embodiment 2.
Referring to fig. 3, in the present embodiment, two ports of the three-way check valve 12 are in a normally open state, and a check valve is disposed in a third port.

The specific process of inflating and deflating the air spring 11 is as follows:

The gas supply method in the embodiment includes:
whether air needs to be supplied to the auxiliary air components is determined, and whether air needs to be supplied may be determined directly by the human eye, for example, or may be determined by a pressure sensor (not shown) connected to the tire. If the flat tire phenomenon appears due to the air leakage of the tire, the tire is judged to need to be inflated.
If the judgment result is yes, the control valve is communicated with the main gas pipeline and the auxiliary gas pipeline to supply gas for the auxiliary gas component.
Specifically, the detected air pressure information in the tire can be continuously transmitted to the control system of the automobile according to the pressure sensor, so that the control system can monitor whether the tire needs air supplement in real time.
When the control system judges that the air needs to be supplied to the tire 8 according to the obtained air pressure information, the control system reminds a user to connect the auxiliary air pipeline to an air valve of an automobile tire, and the automobile is in a static state at the moment. The user connects the second interface O and the third interface I/O through the second two-position three-way electromagnetic valve 5 in the control panel control system, so that the compressed air in the air storage cylinder 4 can be conveyed to the tire to supplement air for the tire.
Further, in the case where the auxiliary air duct is not connected to the second two-position three-way solenoid valve 5, it is necessary to connect the auxiliary air duct 7 to the second port O of the second two-position three-way solenoid valve 5 after it is determined that the tire is required to be inflated.
