ROAD VEHICLE PNEUMATIC SUSPENSION SYSTEM AND ITS CONTROL METHOD Russian patent published in 2017 - IPC B60G17/52 

FIELD: machine building.

SUBSTANCE: group of inventions relates to road vehicle pneumatic suspension system. Pneumatic suspension system comprises several pneumatic springs cylinders matched with one axis pneumatic springs, which are intended for connection with main pressure pipeline via appropriate connection pipelines equipped with road clearance control valve and closing relative to it. Main pressure pipeline is intended for alternatively connection with compressed air source and compressed air drain via corresponding valve, as well as closing relative to them. Cylinders of pneumatic springs arranged on vehicle one axis or on one side are intended for connection in parallel to first connecting pipelines via corresponding second connecting pipeline equipped with second road clearance control valve with main pressure pipeline and closing relative to it.

EFFECT: corresponding throttle is included downstream of second valves in air supply direction.
