Abstract
The railborne bogie vehicle with electrohydraulic brakes and hydropneumatic leveling suspension has in each of its bogies a hydraulic pressure supply unit (9) from which pressure control valves (15, 16) parallel to each other provide pressure to both the hydraulic brakes (19) and the hydropneumatic suspension (20) of that bogie. The back pressure lines (26 and 32) of the electrohydraulic brakes (19) or of the hydropneumatic suspension (20) lead to a hydraulic tank or sump (10) associated with the pressure supply unit (9).
