FIELD: transport.SUBSTANCE: invention relates to machine building. The shock-absorber includes cylinder, rod-piston, piston, three working cavities in each one of which there are internal and external springs with opposite direction of turns. The springs of each cavity are made with different tension. Cylinder has in each cavity one delivery and one drain hole. Delivery holes are connected by pipelines with electrically driven valves connected with delivery main line. The drain holes are connected by pipelines with adjustable throttles the outputs of which are connected into one main line attached to drain line via electrically driven valve. The electrically driven valves and adjustable throttles are assembled into valve and throttle units installed on the cylinder. Throttles and valves are controlled via data bus and signal amplifier unit by electronic control unit. The control unit receives signals from operating mode and various sensors selector.EFFECT: wide range of shock-absorber characteristics adjustment, higher design reliability, manual and manual with automatic correction control of shock-absorber.1 dwg |
