FIELD: transport engineering.
SUBSTANCE: invention relates to vibration protection systems of vehicles, carried loads and crew. Proposed controllable suspension contains hydraulic cylinder, working rod with piston, control system two gangs of compressed gas bottles series-connected by hydraulic main line and consisting of two chambers divided by flexible impermeable partition. Magnetic liquid damper is installed at inlet of each bottle. Said dampers are furnished with electromagnets and are connected with control system. Part gang is connected to piston space of hydraulic cylinder, and second one, to rod space of hydraulic cylinder. Under static conditions, pressures in compressed gas bottles follow the following relatioship 
where 
and magnetic liquid, percent content of magnetic particles 1-10% by volume, is used as liquid, invention provides enlargement of functional capabilities of device by excluding constant influence of pressure in gas space of suspension on rate of reduction of overloads of object to be protected from vibration.
EFFECT: provision of quick action and stability of functioning of controllable suspension, improved reliability.
