HYDRAULIC SYSTEM FOR VEHICLE SUSPENSION Russian patent published in 2008 - IPC B60G21/73 

FIELD: transport.

SUBSTANCE: hydraulic system for vehicle suspension contains casing and at least two front and two rear wheel units. System also contains suspension with front and rear flexible supports between vehicle casing and wheel units for flexible support of vehicle over wheel units. The said hydraulic system contains at least two power cylinders for front and rear wheels respectively located between vehicle casing and wheel units. Each power cylinder includes at least one compression chamber and one reverse stroke chamber. Compression chamber and reverse stroke chamber of each said power cylinder of the front wheel is connected with possibility of fluid flow and respectively with reverse stroke chamber and compression chamber of the diagonal-opposite power cylinder of the rear wheel forming respectively first and second contour of the liquid. Each contour of the liquid secures therein front and rear pressure volume. Front pressure volume of one of the said liquid contours is connected with possibility of fluid flow in rear pressure volume of the other said liquid contour. Hydraulic system secures roll rigidity without securing inclination rigidity or warping rigidity, at that, damp media are installed to damp fluid flow within each pressure volume and between front and rear pressure volumes.

EFFECT: inclination damp without securing of respective damp value of rise or roll.
