Definitions

  • the present invention relates to an air gap control for a suspension / chassis of a track-bound magnetic railway transport system.
  • the vehicles are driven by a long stator motor installed in the track.
  • the electric traveling field in the windings of the long stator motor interacts with the magnetic forces of the permanent magnets of the suspension / chassis. This interaction takes place without contact. It must be ensured that this freedom of contact (air gap) is guaranteed.
  • the magnetic forces that act via the steel track here the sheet metal packs of the long stator
  • This air gap is to be set depending on the load by the air gap control, i.e.
  • the air gap is to be reduced by the servomotors, which has the consequence that the magnetic attraction forces between the permanent magnets of the suspension / chassis and of the guideway with an integrated long stator.
  • Load-dependent mechanical and hydraulic air gap controls and electronically controlled carrying and guiding systems are known.
  • the mechanical air gap control is complex, expensive and has limited functionality, poor adjustability and wide adjustment ranges.
  • a hydraulic air gap control of a track-bound magnetic rail transport system with a linear motor integrated in the guideway and permanent magnets in the suspension / chassis of the vehicle is known, in which a star frame serves as a carrier for all necessary components, with each on the side members of the star frame Hydraulically driven pistons for adjusting the height of the vertical rollers running below the carriageway are arranged at both ends in cylinders, and the height is adjusted using a complex hydraulic and pneumatic system in accordance with the relative displacement between the magnetic railway cabin and the star frame when the external forces change as a result of the interposition Spring device occurs.
  • An electronically controlled carrying and guiding system is complex and only economical for high-speed applications.
  • the object of the present invention is to provide a simple, inexpensive, easily adjustable air gap control system with a small adjustment range. This object is achieved by the characterizing features of claim 1. Advantageous refinements and / or further developments can be found in the subclaims.
  • Figure 1 shows a section through a levitation / chassis of a magnetic railway vehicle with the air gap control according to the invention in cooperation with the magnetic railway track.
  • FIG. 2 shows the top view of the suspension / chassis from FIG. 1.
  • the magnetic track route consists of the route carrier and the route profile.
  • the guideway beam is constructed from the support profile 11 and the cross connector 12.
  • the guideway profile has the support rail 21, the side guide profile 22 and the long stator 23.
  • the suspension / chassis contains the star frame 31, the spindle drive 32, the servomotor 321, the upper vertical rollers 33, the lower vertical rollers 34, the side guide roller 35 and the magnetic strip 36.
  • the magnetic track cabin (not shown) can be connected to the star frame 31, for example via the air bellows 45 and the turntable 44 connected.
  • the air gap control is carried out according to the invention by load-dependent target specifications by means of the actuators 321.
  • the actuators 321 are attached on both sides to the end of the longitudinal members of a rectangular chassis frame 31.
  • the air gap control also makes it possible to design the star frame 31 in such a way that a free space is created in the central region thereof, as shown in FIG. 1. This means that points and crossings in the middle of the magnetic track can be used be carried out in such a way that they protrude above the upper edge of the track profile and can still be driven on by the magnetic railway vehicles.
  • the spindle drive 32 so that the distance between the long stator 23 and the magnetic strip 36 can be increased such that the flow of force is interrupted by separating the electrical field of the long stator 23 and the magnetic field of the permanent magnets of the magnetic strip 36 and so that a safe drive shutdown can be carried out, for example, in the parking area of the transport system or for other requirements.
  • This is of great importance for the safety of driving and shunting operations. This makes it possible to drive different vehicles in the same converter area of the drive system, with the result that this possibility of switching off the drive of individual vehicles means that they can be parked at a short distance from one another and thus a considerable reduction in the length of the parking track is possible.
  • the support arms of the magnetic strips 36 are equipped with support points, not shown, which are positioned above the upper running surface of the support rail 21 in such a way that they support the vehicle weight at the maximum distance required for safe drive shutdown supported on the upper support rail 21 and so a complete relief of the upper vertical rollers 33 is achieved.
  • This avoids deformation of the elastic tread of these vertical rollers during longer service lives.
  • This support of the vehicle weight also acts as a holding brake to safely park a vehicle.
  • the magnetic strip 36 can also be connected to the star frame 31 and the air gap control can be carried out by adjusting the height of the upper vertical rollers 33.

Abstract

Structure à lévitation pour un véhicule à lévitation magnétique dans laquelle les forces de sustentation et de propulsion sont engendrées par le stator longitudinal présent dans la voie et les aimants permanents disposés sur le véhicule, et dans laquelle la reprise de la charge représentée par le véhicule est réglée non pas par une simple commande magnétique de l'écartement, mais par des servomoteurs électriques ou hydrauliques.

Claims (7)

  1. Système de transport à voie magnétique constitué de voies avec stator linéaire intégré (23) et châssis à sustentation avec des aimants permanents fixés sur des glissières magnétiques (36) pour porter et entraîner les véhicules, dans le cas de chacun desquels un cadre rigide (31) sert de support pour tous les composants nécessaires et dans le cas desquels, sur chacun des longerons du cadre rigide (31), des deux côtés, aux extrémités, les mécanismes d'entrainement pour le réglage en hauteur, soit des glissières magnétiques (36) soit des galets de guidage et d'écartement (33, 34), sont disposés pour la régulation de l'entrefer entre les aimants permanents, fixés sur les glissières magnétiques (36), et les stators linéaires (23) et dans le cas desquels on procède au réglage en hauteur en fonction de la charge, système caractérisé
    - par le fait qu'en ce qui concerne le mécanisme d'entrainement, il s'agit d'un moteur de positionnement (321) à entraînement électrique ou hydraulique
    - et par le fait qu'à l'aide d'un dispositif de mesure de la force on mesure la contrainte des galets de guidage supérieurs (33) pour obtenir une valeur de mesure pour la régulation de l'entrefer en cas de contrainte différente provoquée par le poids.
  2. Système de transport à voie magnétique selon la revendication 1, caractérisé par le fait que la régulation de l'entrefer est commandée électroniquement, en fonction d'une valeur prescrite de la contrainte.
  3. Système de transport à voie magnétique selon la revendication 1 ou 2, caractérisé par le fait que de brèves pointes de contrainte sont éliminées de la régulation au moyen d'une régulation à valeur de seuil fonction du poids et/ou du temps.
  4. Système de transport à voie magnétique selon l'une des revendications précédentes, caractérisé par le fait que le cadre rigide (31) est réalisé de façon qu'apparaisse, dans la zone médiane du châssis, dans l'axe longitudinal, un espace libre qui va jusqu'au-dessus du bord supérieur du profilé de voie, pour pouvoir franchir des tronçons médians d'aiguillage ou de croisement.
  5. Système de transport à voie magnétique selon l'une des revendications précédentes, caractérisé par le fait que grâce aux moteurs de positionnement (321), on peut augmenter la distance entre le stator linéaire (23) et la glissière magnétique (36) de façon à interrompre le flux de force par séparation du champ électrique du stator linéaire (23) d'avec le champ magnétique des aimants permanents de la glissière magnétique (36) et à obtenir ainsi un arrêt sûr du mécanisme d'entrainement.
