Description

Spurgebundenes Verkehrssystem Lane-bound traffic system

Die Erfindung bezieht sich auf ein spurgebundenes Verkehrssystem der im Oberbegriff des Anspruchs 1 näher bezeichneten Art. Ein derartiges Verkehrssystem ist bekannt (DT-Zeitschrift "Die Bundesbahn", eft 8, 969 S. 372 bis S. 373).The invention relates to a track-bound traffic system of Art specified in more detail in the preamble of claim 1. Such a traffic system is known (DT magazine "Die Bundesbahn", eft 8, 969 p. 372 to p. 373).

Zum berührungsfreien magnetischen Tragen und Führen von spurgebundenen Fahrzeugen werden bei einem ersten System, dem sogenannten elektromagnetischen Schwebesystem (EMS), am Fahrzeug befestigte Elektromagnete verwendet, die anziehende Kräfte gegenüber ferromagnetischen Ankerschienen an der Fahrbahn ausüben. Bei einem zweiten System, dem sogenannten elektrogynamischen Schwebesystem (EDS), üben am Pahrzeug befestigte supraleitende Spulen abstoßende Kräfte gegenüber kurzgeschlossenen Beiterschleifen oder Beiterschienen an der Pahrbahn aus (Siemens-Zeitschrift 45 (1971) Beiheft "Bahntechnik", S. 181 bis 184). Sowohl bei EMS- als auch bei EDS-Fahrzeugen werden zum berührungsfreien Antrieb Linearmotoren verwendet, wobei aus Gründen der "Systesreinheit" bei EMS-Fahrzeugen eisenbehaftete Kurz- oder Langstatormotoren und bei EDS-Fahrzeugen eisenlose, supraleitende Langstatormotoren vorgesehen wurden (Versuchsstrecken der Firmen Krauss-Maffei und Messerschmidt-Bölkow-Blohm in München-Allach bzw. Manching für EMS-Fahrzeuge und Versuchsstrecke der Firmen Siemens, AEG-?elefunken und Brown, Boverie & Cie in Erlangen für EDS-Fahrzeuge).For contact-free magnetic carrying and guiding of track-bound Vehicles are in a first system, the so-called electromagnetic levitation system (EMS), uses electromagnets attached to the vehicle that oppose attractive forces exercise ferromagnetic anchor rails on the roadway. With a second system, the so-called electro-dynamic levitation system (EDS), practicing attached to the vehicle superconducting coils repulsive forces compared to short-circuited conductor loops or posts on the Pahrbahn from (Siemens-Zeitschrift 45 (1971) supplement "Railway Technology", Pp. 181 to 184). Both EMS and EDS vehicles become non-contact Drive linear motors used, with EMS vehicles for reasons of "system purity" Iron-core short or long stator motors and, in EDS vehicles, ironless, superconducting ones Long stator motors were provided (test routes of the companies Krauss-Maffei and Messerschmidt-Bölkow-Blohm in Munich-Allach and Manching for EMS vehicles and test track from Siemens, AEG-? Elefunken and Brown, Boverie & Cie in Erlangen for EDS vehicles).

Zur Verringerung des Aufwandes für Trag- und Pührungseinrichtungen einerseits und Linearmotoren andererseits ist auch bereits bekannt (DT-OS 22 57 773) einen Langstator-Linearmotor so auszubilden, daß er zugleich Trag- und Führungskräfte zu erzeugen vermag. Dabei sind auf jeder Fahrbahnlängsseite jeweils zwei Blechpakete mit entweder einer gemeinsamen Wanderfeldwicklung oder mit zwei getrennten Wanderfeldwicklungen erforderlich. Der dafür notwendige Materialaufwand bedingt hohe Investitionskosten für die Langstatorausführung.To reduce the work involved in carrying and guiding devices on the one hand and linear motors on the other hand is already known (DT-OS 22 57 773) to train a long-stator linear motor in such a way that it is both carrying and managerial staff able to generate. There are two sheet metal stacks on each longitudinal side of the carriageway with either a common traveling wave winding or with two separate traveling wave windings necessary. The material expenditure required for this results in high investment costs for the long stator version.

Die Aufgabe der Erfindung besteht darin, die bekannten Verkehrssysteme dahingehend zu verbessern, daß ein möglichst einfacher, sicherer leistungsfähiger Betrieb bei möglichst geringen Investitionskosten ermöglicht ist.The object of the invention is the known traffic systems to the effect that a simpler, safer, more powerful Operation is made possible with the lowest possible investment costs.

Die Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.The object is achieved according to the invention by the features in the characterizing part of the claim 1 specified features solved.

Eine bevorzugte Ausführungsform des Verkehrssystems nach Anspruch 1 ist in dem Anspruch 2 gekennzeichnet.A preferred embodiment of the traffic system according to claim 1 is characterized in claim 2.

Bei dem erfindungsgemäßen Verkehrssystem ist zur Schubkraft erzeugung nur das Zusammenwirken der Magnetfelder speziell ausgebildeter Führungsmagnete mit dem Wanderfeld eines fahrbahnseitigen Blechpaketes mit zwei Wanderfeldwicklungen erforderlich. Das Blechpaket verläuft senkrecht stehend in Pahrbahnlängsrichtung und trägt an seinen beiden Seitenflächen jeweils eine Wanderfeldwicklung, denen die fahrzeugseitigen Führungs- und Antriebsmagneten gegenüberliegen. Die Tragkräfte für das Schwebefahrzeug werden in gleicher Weise wie beim herkömmlichen EMS-System durch zwei fahrbahnseitige Ankerschienen und fahrzeugseitige Elektromagnete erzeugt. Durch diese Maßnahmen werden die Investitionskosten für die Fahrbahnausrüstung wesentlich gesenkt.In the traffic system according to the invention is to generate thrust only the interaction of the magnetic fields of specially designed guide magnets with the traveling field of a lane-side laminated core with two traveling field windings necessary. The laminated core runs vertically in the longitudinal direction of the carriageway and carries a traveling field winding on each of its two side surfaces, which the vehicle-side guide and drive magnets are opposite. The load capacities for the suspension vehicle are in the same way as with the conventional EMS system generated by two anchor rails on the roadway and electromagnets on the vehicle. These measures make the investment costs for the pavement equipment significant lowered.

Die Erfindung wird mit ihren weiteren Einzelheiten und Vorteilen anhand der Zeichnung näher erläutert.The invention will be based on its further details and advantages the drawing explained in more detail.

Das in der Figur im Querschnitt dargestellte erfindungsgemäße Verkehrssystem umfaßt ein Pahrzeug 1, das längs einer Pahrbahn 2 berührungsfrei getragen, geführt und angetrieben wird. Das Pahrzeug 1 weist ein elektromagnetisches Tragsystem 3 mit fahrzeugseitigen Tragmagneten 4, 5 und fahrbahnseitigen ragankerschienen 8, 9 aus. Zur Regelung der Tragmagnete 4, 5 sind Meßfühler 12 und 13 auf der Unterseite des Pahrzeugs 1 vorgesehen, welche den Abstand zwischen Fahrzeug 1 und Pahrbahn 2 messen. Insoweit entspricht das erfindungsgemäße Verkehrssystem dem herkömmlichen EMS-System (vgl. z.B. "Die Bundesbahn", Heft 8, 1969, S. 372, Bild 1).The traffic system according to the invention shown in cross section in the figure comprises a Pahrzeug 1, which is carried along a Pahrbahn 2 without contact, guided and is driven. The vehicle 1 has an electromagnetic support system 3 with support magnets 4, 5 on the vehicle side and rail anchor rails 8, 9 off. To control the support magnets 4, 5, sensors 12 and 13 are on the underside of the Pahrzeugs 1 provided which the distance between vehicle 1 and Pahrbahn 2 measure. To that extent corresponds the traffic system according to the invention the conventional EMS system (see e.g. "Die Bundesbahn", Issue 8, 1969, p. 372, Image 1).

Das EMS-Tragsystem 3 ist mit einem Langstator-Linearmotor 140 kombiniert, der aus einer bei der Fahrbahn 2 angebrachten Drehstromwicklung 150 und mehreren, an der Unterseite des Fahrzeugs 1 befestigten, ferromagnetischen, regelbaren Sangstator-Erregermagneten 160 besteht. Ein derartiger Langstator-linearmotor ist bekannt und braucht daher in seiner Wirkungsweise nicht näher erläutert zu werden. Der Motor 140 ist in bevorzugter Weise in der Fahrbahn- und Fahrzeugmitte angeordnet.The EMS support system 3 is combined with a long stator linear motor 140, which consists of a three-phase winding 150 attached to the roadway 2 and several, on the underside of the vehicle 1 fixed, ferromagnetic, adjustable Sangstator exciter magnets 160 exists. Such a long-stator linear motor is known and therefore needs not to be explained in detail in its mode of action. The motor 140 is more preferred Way arranged in the lane and center of the vehicle.

Erfindungsgemäß ist eine stehende bzw. vertikale Einbaulage der Drehstromwicklung 150 und der Erregermagneten 160 vorgesehen. Die Drehstromwicklung 150 ist an einer vertikalen, ferromagnetischen Schiene 18 montiert, die auf beiden vertikalen Oberflächen mit der Drehstromwicklung 150 belegt ist.According to the invention, the three-phase winding is installed in an upright or vertical position 150 and the excitation magnet 160 are provided. The three-phase winding 150 is on one vertical, ferromagnetic rail 18 mounted on both vertical surfaces with the three-phase winding 150 is occupied.

Dementsprechend besteht jeder Erregermagnet 160 aus zwei Teilen, wobei jeder Magnetteil einer zugeordneten Drehstromwicklung 150 gegenüberliegt.Accordingly, each exciter magnet 160 consists of two parts, wherein each magnetic part of an associated three-phase winding 150 is opposite.
