Description
während der Fahrt vornehmen. Vorzugsweise erfolgt die Relativverstellung auch abhängig von sich ändernden Störkräften, die z. B. von Wind, Zentrifugalkräften oder dergleichen herrühren. Dabei kann es sich um die Berücksichtigung niederfrequenter Störkräfte handeln oder auch darum, daß die Elektromagnete mit höherer Frequenz den Unebenheiten des Fahrwegs folgen, ohne daß die Dauermagnete die Massenbeschleunigung der Elektromagnete mitmachen müssen.while driving. The relative adjustment is preferably also carried out as a function of changes Disturbing forces that z. B. from wind, centrifugal forces or the like. This can involve taking into account low-frequency interference forces or the fact that the electromagnets follow the unevenness of the driveway with a higher frequency, without that the permanent magnets have to take part in the mass acceleration of the electromagnets.
Vorzugsweise ist die erfindungsgemäße Relatiwerstellung aufgrund von Informationen aus einem Elektromagnetregelkreis gesteuert, wobei die Regelung auf minimale Stromstärke der Elektromagnete gehen kann.The relative setting according to the invention is preferred controlled on the basis of information from an electromagnetic control circuit, with the regulation at minimum Amperage of the electromagnet can go.
Die bevorzugte Tolerierbarkeit von Gleitkontakt zwischen Fahrzeugteilen und entsprechenden Fahrwegteilen erlaubt eine weitere Reduzierung der Regelungsleistung für die Elektromagnete. An konkreten Ausführungsmöglichkeiten seien kufenartige Verkleidung von Magnetpolen, Kunststoffgleitflächen am Fahrweg, Einsatz von Material-Gleitmittel-Mischungen, Austretenlassen von Gleitmittel, z. B. Wasser, Luft, Fett, Molybdändisulfid, Polytetrafluoräthylen, vorzugsweise gesteuert durch einen Annäherungs- oder Berührungssensor, genannt.The preferred tolerability of sliding contact between vehicle parts and corresponding guideway parts allows a further reduction in the control performance for the electromagnets. In terms of specific implementation options be skid-like cladding of magnetic poles, plastic sliding surfaces on the guideway, use of material-lubricant mixtures, leakage of lubricant, e.g. B. water, air, fat, molybdenum disulfide, Polytetrafluoroethylene, preferably controlled by a proximity or touch sensor, called.
Das bevorzugte Verbleiben der Dauermagnetposition im Bereich des Ausgleichs der statischen Fahrzeuglast beim Ausfall der Elektromagnetregelung kann über Stromlosschalten der Elektromagnete erfolgen.The preferred retention of the permanent magnet position in the area of balancing the static vehicle load in the event of failure of the electromagnetic control, the electromagnet can be de-energized.
Der bevorzugte Einsatz von Magnetmaterial mit μ.ηι kleiner als 2,5 führt zu einem flacheren Verlauf der Kraft-Spaltweite-Kennlinie des Systems, wodurch sich die Elektromagnetregelung weiter vereinfacht. In der gleichen Richtung wirkt das Vorsehen von Platten z. B. aus Aluminium oder glasfaserverstärktem Kunststoff an der Fahrzeugseite oder der Fahrwegseite des Luftspalts.The preferred use of magnetic material with μ. η ι less than 2.5 leads to a flatter course of the force-gap width characteristic curve of the system, which further simplifies the electromagnetic control. The provision of plates acts in the same direction, e.g. B. made of aluminum or glass fiber reinforced plastic on the vehicle side or the driveway side of the air gap.
Die bevorzugten vertikalkraftübertragenden Kopplungseinrichtungen führen dazu, daß bei Ausfall der Elektromagnetregelung eines Fahrzeugs das in einem Fahrzeugzug anschließende Fahrzeug kompensierend wirken kann.The preferred vertical force transmitting coupling devices lead to the failure of the electromagnetic control of a vehicle in one Vehicle train connecting vehicle can have a compensating effect.
Das erfindungsgemäße Fahrzeug eignet sich insbesondere für eine Magnetfahrtechnik, bei der der Fahrweg mit einem Wanderfeldstator ausgerüstet ist und die Dauermagnete sowie die Elektromagnete in einer mit dem Wanderfeldsf.ator übereinstimmenden Polanordnung und Polteilung vorgesehen sind, so daß ein fahrzeugerregter, synchroner Liniearmotor entsteht, der zugleich das Fahrzeug hebt.The vehicle according to the invention is particularly suitable for a magnetic driving technique in which the travel path is equipped with a traveling field stator and the permanent magnets and the electromagnets in one with the pole arrangement corresponding to the traveling field sensor and pole pitch are provided, so that a vehicle-excited, synchronous linear motor is created, which at the same time the vehicle lifts.
Die Zeichnungsfiguren dienen einer weiteren Erläuterung der Erfindung.The drawing figures serve to further explain the invention.
F i g. 1 zeigt die Verhältnisse im Schema. Der Fahrzeugkörper Fz ist gegenüber den Dauermagneten DM und gegenüber den Elektromagneten EMU bzw. EMO separat abgefedert. Die Federung kann passiv oder aktiv sein und kann sich zusätzlich nach Spaltweitesensoren richten. Mit s ist die Spaltweite zwischen dem Stator und den Dauermagneten DM bezeichnet.F i g. 1 shows the relationships in the scheme. The vehicle body Fz is cushioned separately from the permanent magnet DM and from the electromagnet EMU or EMO. The suspension can be passive or active and can also be based on gap sensors. The gap between the stator and the permanent magnets DM is denoted by s.
F i g. 2 zeigt die Verhältnisse, wenn Elektromagnete EMU nur unterhalb des Fahrwegwanderfeldstators vorhanden sind. Das Gewicht des Fahrzeugs Fz wird teils von den Dauermagneten DM und ieiis von den Eiekiromagneten EMU getragen, wobei eine Verringerung der Spaltweite s zu einer Verringerung des Kraftanteils der Elektromagnete EMUführt. F i g. 2 shows the situation when electromagnets EMU are only present below the travel path wandering field stator. The weight of the vehicle Fz is partly borne by the permanent magnets DM and ieiis by the Eiekiromagneten EMU , a reduction in the gap width s leads to a reduction in the force portion of the electromagnets EMU.
F i g. 3 zeigt die Verhältnisse, wenn sowohl Elektromagnete EMU unterhalb des Stators a!s auch Elektromagnete EMO oberhalb des Stators vorhanden sind. Hierbei kann die Spaltweite s und damit die Anziehungskraft der Dauermagnete DM so eingerichtet werden, daß sie im Mittel etwa das Fahrzeuggewicht trägt Die Elektromagnete EMU und EMO stehen zur Spaltweitenstabilisierung und zum Ausgleich positiver oder negativer, zusätzlicher Vertikalkräfte zur Verfügung.F i g. 3 shows the situation when there are both electromagnets EMU below the stator as well as electromagnets EMO above the stator. Here, the gap width s and the attraction of the permanent magnets DM be set up so that they average about vehicle weight contributes Electromagnets EMU and EMO are gap width stabilization and positive to balance or negative, additional vertical forces available.
