ABSTRACT:
A hydropneumatic suspension system having the characteristic of being able to vary at will, and independently of each other, the rigidity of the sustaining and load-adaptation means of each vehicle wheel, consisting of a series of sensors for measuring the dynamic attitude of the vehicle connected to a central electronic control unit, and respective hydraulic dampers of adjustable internal pressure, which support the wheels and are connected to respective hydropneumatic service accumulators the internal pressure of which is controlled by solenoid valves controlled by the central control unit; hydraulic energy can be supplied to the accumulators by, for example, the servo-steering system pump via a common main accumulator. (FIG. 1).
