  • Patent number: 5454329
    Abstract: Anticentrifugal active lateral suspension apparatus for balancing the non-compensated centrifugal acceleration along a curve of a railway vehicle, including fluid pressure jacks, interposed transversely between the body and the opposite sides of each bogie, vales for connecting alternatively the jacks with a source of fluid under pressure, and transducers adapted to detect the non-compensated centrifugal acceleration and to generate corresponding piloting signals for the valves so as to apply, by the jacks, a force contrasting the centrifugal force acting on the body. The transducers comprise two accelerometers placed in proximity of the opposite ends of the vehicle and whose signals are supplied to an electronic processing unit arranged selectively to pilot the vales in different modes. The valves are electronic servo valves or proportional valves.
