FIELD: machine building.
SUBSTANCE: pneumatic damper consists of case and hollow piston forming closed working volume for working medium and of fasteners of device or system. A free of fastening edge of the case is equipped with a device consisting of brake shoes and a drive pressing them at a proper moment to external surface of the hollow rod with required force. The first and the second additional closed volumes are communicated with working volume by means of valve units and are made as separate tanks of high and low pressure with devices of automatic inlet and outlet of working medium from closed working volume. A processor controls operation of devices for inlet and outlet and also operation of a drive of the brake shoes. By means of sensors the processor continuously tracks specified working parametres of the damper according to one or a rank of programmed damping characteristics. The tanks can be replaceable, while the processor is common for several dampers.
EFFECT: simplified design, upgraded quality of damping and reliable contact of vehicle wheel with road bed.
