Abstract
The hydropneumatic suspension system includes first and second pairs of suspension units; each pair of suspension units is adapted to be hydraulically controlled in the same manner. Each suspension unit includes upper and lower cylinder compartments divided by a main piston. The upper cylinder compartment and the lower cylinder compartment of each of the first pair of suspension units are respectively connected to the lower cylinder compartment and the upper cylinder compartment of each of the second pair of suspension units. Five solenoid valves are hydraulically connected to the suspension units and actuated, when it is required to lift a vehicle wheel, such that hydraulic fluid under pressure is supplied to the upper cylinder compartments of the first and second pairs of suspension units and thereafter hydraulic fluid in the upper cylinder compartments of one of the first and second pairs of suspension units is supplied to the lower cylinder compartments of the other pair.
