摘要： A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.

摘要： The invention relates to a railway vehicle comprising a car (14) and a bogie (16). The bogie (14) comprises a chassis (28) and a secondary suspension system (30). The secondary suspension system (30) comprises: a set (34) of springs; a jack (36) comprising two ends (44, 46); and a supply device (38) of the jack (36). The jack (36) is configured to go from a first so-called retracted configuration in which the jack (36) is only connected to the car (14) by the first end (44) to a second so-called deployed configuration in which the jack (36) is also connected to the chassis (18) by the second end (16).
The power supply device (38) is configured, in the deployed configuration, to supply the jack (36) so as to move the car (14) away from the chassis (28) or to keep the distance between the car (14) and the chassis (28) constant.-

摘要： A carbody support device of a railway vehicle, including support mechanisms installed between a front bogie and a carbody and between a rear bogie and the carbody in a traveling direction, and supporting the carbody against the respective bogies. The support mechanisms regulate both the front bogie and the rear bogie inclining in the same vehicle width direction with respect to the carbody when the railway vehicle travels through a curve, while the support mechanisms permit the front bogie and the rear bogie inclining in different vehicle width directions.

摘要： This track-guided vehicle is provided with a car body, and a bogie that supports the car body from the bottom, and has a frame capable of pivoting around an axis perpendicular to a track. The bogie is provided with: a car body tilting part that tilts the car body to the left and right in the direction of travel; a detection part that detects the amount of pivot of the frame; and a tilt control part that allows the car body to be tilted by the car body tilting part on the basis of the amount of pivot detected by the detection part.

摘要： The railway car comprises a subframe 40 disposed below a floor of the car body with a clearance therebetween, and a bogie 30 disposed below the subframe 40 with a clearance therebetween, wherein car body 10 and subframe 40 are connected via a first center pin 50 protruding downward from car body 10 or via a first center pin 50 protruding upward from subframe 40 toward car body 10, and subframe 40 and bogie 30 are connected via a second center pin 70 protruding downward from the subframe 40. A two-step bumper 61 is disposed between the first center pin 50 and the corresponding adjacent member, and two-step bumper 61 is disposed on both sides of center pin 50 in the width direction of car body 10. Car body 10 swings in the width direction when the bogie passes a point. After passing the point, car body 10 returns to its original position by the force of two-step bumper 61.

摘要： A method and an apparatus for generating a sensor signal related a track-banking angle of a banked section of track traversed by a train car wherein a track-banking angle value basically is determined from measured values of the rolling angular speed and yaw speed of the car chassis. A track-banking angle (.PHI.g) is determined in an observer unit (2), preferably estimated by use of an inverse gyro system simulation (10) of a measured-value generator (6), and compared, as an estimated track-banking angle (.PHI.gb), to a track-banking angle (.PHI.gs) determined from the transverse acceleration (aq), the yaw speed (.omega.G) and the train speed (v), as information about the track-banking angle (.PHI.g). A resulting difference (.DELTA..PHI.g) is filtered via a regulating circuit formed by a feedback from a comparator (11) to the inverse gyro system simulator (10). This signal, in the form of a track-banking angle (.PHI.b), as the signal representing the real track-banking angle (.PHI.g), can be fed subsequently to an angle-of-inclination generator unit (4) for generating an actuation and switching signal (.phi..sub.N) for controlling the car chassis inclination. A further observer unit (3) can be integrated into the system for increasing the dynamics. Track path data and track geometries are stored in this further observer unit (3), so that when a track path is recognized, it is possible to preset a control system (5) or the actual car-body inclination system (1).
