FIELD: transportation. ^ SUBSTANCE: shock-absorber comprises body, in which mechanical gear is installed, which transforms reciprocal motion into rotary one. Mechanical gear includes vertical screw with ball nut and spiral spring installed in movable jacket. On jacket cover two or more damping devices are installed, which are rigidly connected to head of vertical screw. External end of spiral spring is connected to movable jacket, and internal end is rigidly fixed to external ring connected to ball nut installed in movable jacket. Body is equipped with fixators for control of shock absorption modes. ^ EFFECT: increased reliability and durability of operation, increased efficiency and stability of oscillations suppression, increased smoothness of travel. ^ 3 cl, 2 dwg |
