  • Process and device for regulating the earth-related inclination of railroad vehicle boxes
    Patent number: 5784969
    Abstract: A process and device for controlling the inclination of rail vehicle boxes in a railway vehicle, the rail vehicle boxes sitting on spring-suspended bogies with at least one pair of wheels which can be pivoted about the longitudinal axis. The centrifugal acceleration in the horizontal plane is determined and a setpoint is calculated for the absolute inclination of the box relative to the earth. An actual value of the absolute inclination of the box relative to the earth is determined and at least one control signal is formed from the difference between the setpoint and the actual value of the absolute inclination of the box. The angle between the bogie and the box is adjusted across the direction of travel as a function of the control signal thus formed. This makes it possible to control the inclination of the box independently of the type of track banking design and any possible interference.
