Abstract
The hydropneumatic axle suspension for vehicles, especially the front axle thereof, cooperates with at least one suspension cylinder (10) connected to a hydraulic accumulator (26; 24) on both its ring side (14) and the piston side (12). The hydraulic accumulator (26; 24) is triggerable by control electronics (18) with the aid of a valve unit (30; 28) that can be allocated to the hydraulic accumulator (26; 24). The ring side (14) of the suspension cylinder (10) is connected to a pressure value sensor (DA-R) which transmits its measured pressure values to the control electronics (18). The pressure value sensor (DA-R) located on the ring side is connected to the discharge end (38) of the valve unit (30), which can be associated with the ring side (14) of the suspension cylinder (10).
