AUTOMOBILE HYDROPNEUMATIC SUSPENSION Russian patent published in 1996 - IPC

FIELD: transport; suspensions of road vehicles. SUBSTANCE: hydraulic suspension has shock absorbing strut with cylinder and piston moved under action of hydraulic medium, for instance oil. Oil flows in straight direction at pressing and in return direction at release through hydraulic coupling member between shock absorbing strut and at least one hydropneumatic spring accumulator containing medium to be compressed. Spring accumulator builds up hydraulic pressure which creates springing effort in shock absorbing strut by loading the piston. At process of release, connection between shock absorbing strut and spring shock absorber is alternately gets closed and opened. EFFECT: enhanced quality of shock damping. 14 cl, 10 dwg
