FIELD: transport.
SUBSTANCE: proposed damper comprises body, cylinder, rod with piston and extra piston to divide said cylinder to three chambers. Different-stiffness spring is fitted in every said chamber. Said chambers are communicated by pipelines via controlled throttles and solenoid valves. Pipeline is connected with feed main and discharge line. Throttles and valves are controlled by control unit in response to signals fed by the driver.
EFFECT: wider adjustment band, simplified design.
