FIELD: transport. ^ SUBSTANCE: invention relates to vibration killers. Suspension comprises moving parts and base. Lower shackle is articulated by means of support on said base. Said support is rigidly jointed with the base. Suspension flexible element is made up of three interconnected flexible elements. Helical coil spring is arranged at the center to rest, by one end, upon chassis moving parts web and, by opposite end, on hydraulic damper circular flange. Said damper is formed by two aligned cylindrical shells. Tight annular chamber is formed between outer and inner shells. Movable annular flange with seals arranged on inner and outer surface covers top section of said chamber while annular washer covers its bottom section. Annular chamber accommodates annular piston with throttling holes. Said piston is articulated with annular flange whereon thrusts the spring. Guide rod is located coaxial with said shells. Lower end of guide rod is rigidly jointed with lower shackle while its upper end is locked on aforesaid web by flexible element made from elastomer. ^ EFFECT: higher efficiency of vibration isolation. ^ 1 dwg |
