Fliehkräfte aktiv-ausgleichende Aufhängung für Schienenfahrzeuge

Anticentrifugal active lateral suspension apparatus for balancing the non-compensated centrifugal acceleration along a curve of a railway vehicle (F), including fluid pressure jacks (8, 9), interposed transversally between the body (1) and the opposite sides of each bogie (2, 3), valve means (18, 19) for connecting alternatively the jacks with a source of fluid under pressure (14) and transducers adapted to detect the non-compensated centrifugal acceleration and to generate corresponding piloting signals for the said valve means (18, 19) so as to apply, by means of the said jacks (8, 9), a force contrasting the centrifugal force acting on the body. The transducers comprise two accelerometers (21, 22) placed in proximity of the opposite ends of the vehicle (F) and whose signals are supplied to an electronic processing unit (20) arranged selectively to pilot the said valve means (18, 19) in different modes. The valve means (18, 19) are electronic servo valves or proportional valves.
