Abstract: On a railway vehicle with a car body and a truck with an undercarriage, the car body is supported on the truck by means of connecting devices. To achieve increased operating safety even in the event of a malfunction or failure of the connecting devices, the actuator is fastened rigidly on one end to the truck, and is connected to the car body by means of the mechanical series system consisting of a ball-and-socket joint and a sliding connector.

Abstract: A coupling element unit with spring action is located between a car body and an undercarriage of a railway vehicle. To largely relieve the coupling element unit from forces that act at a right angle to the suspension direction, a sliding adapter is provided that has two sliding elements and that can be displaced with respect to one another parallel to a floor of the car body.

Abstract: A rail vehicle equipped with a support actuator of variable vertical length mounted between a vehicle body and a running gear located underneath. In order to maintain an operational supporting device and adequate ride comfort after a failure or overload of the support actuator, an emergency spring coaxial with the support actuator is provided, which only becomes effective when the stroke of the support actuator falls short of a preset value.

Abstract: The invention relates to a tilt control for the superstructure of a rail vehicle, that includes a transversal acceleration sensor and a tilt control device controlled therefrom for tilting the superstructure along its longitudinal axis in relation to the running gear or the bogie supporting the superstructure. A low-pass filter is connected in the signal path between the transversal acceleration sensor and the tilt control device. In order to at least amply compensate the operation time of the low-pass filter, a steady state member is connected in the signal path between the transversal acceleration sensor and the low-pass filter, whose output signal is selected at least in the middle segment of a predetermined measuring value of the transversal acceleration values to be detected in such a way that the transversal acceleration in the superstructure remains almost constant in said segment.
