FIELD: transport.

SUBSTANCE: invention relates to automotive industry. Proposed suspension for transport facility equipped with front and rear flexible supports, comprises four wheel power: cylinders and device for isolating operating conditions with four compensation chambers. In compliance with particular version of proposed invention, aforesaid isolating device comprises three cylindrical parts, two of them, of identical diametre, being arranged on both ends of central cylindrical part with larger diametre. Compensation chamber are made by piston rod assy comprising two pistons fitted in lateral cylindrical parts of said isolating device and central piston arranged in its central part. Lateral pistons are coupled by rods with central piston. In compliance with another version, isolating device comprises one cylindrical part, while central web acts as central piston. Compression chamber of each wheel power cylinder is communicated with rebound chamber of adjacent wheel power cylinder and appropriate compensation chamber of isolating device.

EFFECT: higher stiffness of suspension in roll and fore-and-aft tilt.
