Description

Technical Field

[0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a gas cooling system and method for an air spring of a vehicle. Background Art

[0002] With the rise of domestically produced new energy vehicles, some relatively high-end auto parts have also been transferred to mid- and low-end models. For example, more and more models are equipped with air springs, which can effectively improve the comfort of the vehicle.

[0003] When a vehicle equipped with an air spring is driving, the temperature of the gas in the gas chamber of the air spring will gradually increase due to bumps in the road. When the temperature of the gas in the gas chamber reaches a certain temperature value, it will have a significant impact on the vibration reduction performance of the air spring and reduce the comfort of the vehicle during driving.

[0004] However, since there is no mature technology to cool the gas in the gas chamber of the air spring, the existing air springs generally have a technical problem of being unable to cool the gas in the gas chamber, which will cause unstable vibration reduction performance. Summary of the invention

[0005] In order to solve the above-mentioned defects of the prior art, the present invention provides a vehicle air spring gas cooling system and method to solve the technical problem that the existing air springs generally cannot cool the gas in the gas chamber, resulting in unstable vibration reduction performance.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A vehicle air spring gas cooling system includes a gas pipeline, a gas pipeline cooler, a gas pump, a solenoid valve, a control module arranged on the vehicle, and an air conditioning refrigeration circuit and an air spring of the vehicle;

[0013] The air stored in the air storage box is used to mix with the air in the gas pipeline for cooling.

[0014] By arranging the air storage box, the gas pipeline cooler and the gas pump in sequence on the gas pipeline in the direction from the gas outlet to the air inlet, the gas in the gas chamber can first enter the air storage box for mixing and cooling after entering the gas pipeline, and then enter the gas pipeline cooler for heat exchange with the air-conditioning refrigeration circuit; the cooling efficiency can be improved and the refrigeration load of the air-conditioning refrigeration circuit can be reduced.

[0015] Furthermore, the air spring is also used to send intracavity air pressure information to the control module; the control module is used to control the opening and closing of the gas pump and the two solenoid valves according to the received intracavity air temperature information, and the control module is also used to control the output air pressure of the gas pump according to the received intracavity air pressure information after the gas pump is turned on.

[0016] By making the control module control the output air pressure of the gas pump according to the received air pressure information in the cavity after the gas pump is turned on, the output air pressure of the gas pump can be adjusted according to the air pressure value in the gas chamber to maintain the air pressure in the gas chamber stable, thereby preventing the vibration of the vehicle caused by the unstable air pressure in the gas chamber during the cooling of the gas in the gas chamber, thereby reducing the comfort of the vehicle during driving.

If it is detected that the air temperature value is greater than the first preset temperature value, the control module controls the gas pump and the two solenoid valves to open at the same time.

[0028] Furthermore, the method of using the control module to control the gas pump and the two solenoid valves to open simultaneously according to the received cavity air temperature information includes the following steps:

[0029] Step 1: The control module obtains a first air temperature value in the gas chamber according to the received air temperature information in the chamber;
