VEHICLE HYDROPNEUMATIC SUSPENSION Russian patent published in 2009 - IPC B60G17/04 

FIELD: transport.

SUBSTANCE: proposed suspension comprises hydraulic cylinder of the L.H. side wheel axle suspension and that of the R.H. side wheel axle suspension. Every hydraulic cylinder incorporates a housing, con rod and piston which divides the cylinder inner chamber into head end and rod end. The L.H. side front axle wheel suspension cylinder piston end communicates via hydraulic line and L.H. side wheel suspension valve with the L.H. side front axle wheel suspension pressure tank and, via the throttle and hydraulic line, with the rod end of the R.H. side front axle wheel suspension hydraulic cylinder. The R.H. side front axle wheel suspension cylinder piston end communicates via hydraulic line and R.H. side wheel suspension valve with the L.H. side front axle wheel suspension pressure tank and, via the throttle and hydraulic line, with the rod end of the L.H. side front axle wheel suspension hydraulic cylinder. The L.H. side rear axle wheel suspension cylinder piston end communicates via hydraulic line and L.H. side wheel suspension valve with the L.H. side rear axle wheel suspension pressure tank and, via the throttle and hydraulic line, with the rod end of the R.H. side rear axle wheel suspension hydraulic cylinder. The R.H. side rear axle wheel suspension cylinder piston end communicates via hydraulic line and R.H. side wheel suspension valve with the R.H. side rear axle wheel suspension pressure tank and, via the throttle and hydraulic line, with the rod end of the L.H. side rear axle wheel suspension hydraulic cylinder.

EFFECT: automatic reduction of center of masses during vehicle turns in motion, higher stability of vehicle and decreased roll.
