METHOD FOR CONTROLLING DYNAMIC STATE OF VEHICLE SUSPENSION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC F16F15/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in vehicle suspensions. Device for control of dynamic state of suspension consists of two elastic units – spring and unit of series-connected pneumatic bottles, and control system. Pneumatic springs represent pneumatic resilient elements with support surfaces. Control system includes compressor, valves for transfer of compressed air into pneumatic tanks with capabilities of controlled "release" of excess pressure, sensors for measurement of vibration level of protection object. Method for control of dynamic state of suspension includes possibility to adjust rigidity of elastic elements. State control is performed taking into account values of dynamic reactions in points of contact of elastic elements with support surfaces and between each other in the presence of an intermediate mass inertia element between pneumatic springs. Dynamic stiffness of suspension is formed depending on intensity of external action by adjusting ratio of stiffness of pneumatic elements. Stiffness parameters are controlled due to signals coming from sensors characterizing dynamic state of suspension and external action.

EFFECT: higher efficiency of suspension.
