SUSPENSION OF TRANSPORT FACILITY Russian patent published in 2013 - IPC B60N2/50 F16F15/04 

FIELD: transport.

SUBSTANCE: invention relates to automotive seats, particularly, to driver seat dampers. Suspension comprises moving parts and 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. Hydraulic damper is composed of two aligned cylindrical inner and outer sleeves that make a tight annular chamber. 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 cylinder is fitted inside said chamber to divide it in two parts: top and bottom. Said piston is furnished with orifice holes to allow damping fluid flow from annular chamber bottom to its top and vice versa. Said piston is articulated with annular flange whereon thrusts the spring. 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. Guide rod top part groove accommodates damping ring to kill suspension oscillation in horizontal plane.

EFFECT: higher efficiency of vibration isolation.
