Abstract
A hydropneumatic vehicle suspension system has two strut assemblies with hydraulic struts that act upon at least one hydropneumatic piston-type accumulator. The accumulator has a separating piston charged with hydraulic pressure on one side of a storage volume, pneumatic pressure on the other side of a spring chamber and a supplementary spring force via a separating piston rod that extends out of the piston-type accumulator. The supplementary spring force is generated by a pressure medium cylinder that acts upon the separating piston rod by connecting the pressure medium cylinder with at least one pressure accumulator that generates a prestress pressure.
