摘要： A hydropneumatic system (51) for suspensions of vehicle wheel assemblies is provided, for each suspension, with a respective hydropneumatic cylinder (1) having a first and a second body (10,11), which can move axially relative to each other and define respective chambers (14,15), axially separated from each other via a piston element (30); the latter is coupled in a fluid-tight manner to the second body (11) and floats between two stroke end positions in response to the pressures in the two chambers (14,15); the two chambers (14,15) of each hydropneumatic cylinder (1) communicate respectively with a hydraulic supply line (52) and with a pneumatic supply line (57); the system (51) further has a pressurization device which sets the pressure in the pneumatic supply line (57) to a value at least equal to the pressure in the hydraulic supply line (52).

摘要： A system 201, 202, 300, 400, 500 for use in a vehicle to control movement of a vehicle body relative to each wheel of the vehicle. The system comprising at least two hydraulic damper assemblies 210, 211, 310, 311, 410, 411, 510, 511 or shock absorbers, each configured to connect the vehicle body to a respective wheel of the vehicle. The system further comprises at least one hydraulic actuator 100, 225, 325, 425, 525 configured to be in fluid communication with at least two of the hydraulic damper assemblies. The at least one hydraulic actuator comprises at least two fluid chambers 150, 154, each comprising an aperture 157, 158 at a first end thereof, and at least two actuator pistons 140, 144, each slidable within respective fluid chambers in a first direction, D1, thereof for moving hydraulic fluid into the fluid chamber via the aperture and in a second direction, D2, for moving hydraulic fluid out of the fluid chamber via the aperture. Further, each of the at least one actuator pistons is operatively connected to a drive unit 110, 228, the drive unit being configured to generate a translation of the at least one actuator pistons in the first and second direction. Still further, the at least one hydraulic actuator is configured to adjust a preload of the at least two hydraulic damper assemblies to control at least one of a pitching movement of the vehicle body relative to the wheels of the vehicle; and a rolling movement of the vehicle body relative to the wheels of the vehicle.
