Definitions
- the invention relates to an electrodynamic rail brake according to the features of the preamble of claim 1.
- the objective here was to reduce the de-excitation time of the magnetic yoke so that the cycle times between two processes running on the same track brake can be shortened and thus the performance of the system can be increased.
- the constructive basic principle of the electrodynamic rail brake according to which the U-shaped magnetic trough is the supporting element, in which the running rail is inserted, has always been maintained. This still leads to electrodynamic rail brakes bulky and bulky components that can be installed only with great technical complexity in existing track systems. Usually, when installing such brakes in an existing track a complete disassembly of the existing track and a subsequent complete rebuild the affected track section (track to the changed altitude adjust, weld, etc ...) is necessary.
- the invention has for its object to provide an electrodynamic rail brake, which allows a comparison with the prior art simpler installation in existing track systems or easier maintenance of the electrodynamic rail brake.
- parts of the brake system, especially the U-shaped ferromagnetic iron body, without intervention in the superstructure to be interchangeable.
- the inventive concept provides that the attachment of the U-shaped ferromagnetic trough body at the foot of the running rail comprises a plurality of hook-shaped clamping pieces which engage over the rail on its upper side and at the same time are screwed to the base plate of the U-shaped trough body.
- the screw is designed so that the screw from the rail head ago (ie from above) can be introduced.
- the electrodynamic track brake from a plurality of individual U-shaped, each forming a magnetic trough ferromagnetic trough body constructed, each having on both legs bobbin and a pair of opposing and slidable on the pole faces of the magnetic troughs brake beams.
- the inventive basic principle of the suspension of the U-shaped trough body on the rail allows for the first time a division of the bulky, one-piece track brake in several individual brake modules, each working independently and are interconnected only control technology to form a whole.
- the individual modules are each individually controllable, which allows for a variety of possible braking scenarios and thus increases the flexibility of the system and on the other hand also increases the redundancy and thus reliability of the system.
- a particularly useful development of the invention is therefore to be seen in the fact that the dimensions of the U-shaped ferromagnetic trough body in the direction of the rail longitudinal axis are smaller than the free distance between two adjacent sleepers of the track grid.
- the individual modules of the electrodynamic rail brake can be mounted in the threshold compartments of the existing track grid. It is now only necessary to sweep the threshold compartments to a given depth of gravel. However, exposing the threshold compartment to the depth of the sill sole is by no means required. In particular, thus can also be dispensed with the hitherto necessary, cumbersome removal of the track yoke together with subsequent assembly of the U-shaped trough body and the laying and fixing of the rails within this trough body.
- the base plate and side legs of the U-shaped ferromagnetic trough body can be screwed together.
- the U-shaped trough body can be mounted in a particularly simple manner on the running rail or be dismantled from the running rail. This is of great benefit not least in the event of any repairs to the electrodynamic track brake.
- each brake bar is mounted displaceably on a support plate.
- a suitable selection of the material pairing between the brake beam and carrier plate favors the sliding of the brake strips significantly and can significantly improve the energy efficiency of the electrodynamic brake.
- a structurally simpler mounting of the brake beams on the pole faces of the magnetic trough is conceivable; However, this is usually accompanied by a less favorable material pairing and thus higher friction losses.
- the dimension of the support plate and the brake beam in the direction of the rail longitudinal axis is greater than the free distance between two adjacent sleepers of a track grid, but at the same time smaller than the measure of the threshold pitch.
- threshold division is to be understood as meaning the free distance between two adjacent sleepers of the track grate plus a threshold width in the rail longitudinal direction.
- a particularly effective development of the inventive concept provides that at least one support plate is inclined outwards. In this way, it is achieved that a rail vehicle wheel, which enters the currentless and closed state of the electrodynamic brake in the brake groove formed by the opposing brake beams, these brake beams must not be forced apart. In certain applications, this is due to the friction of the brake beams On the pole faces of the magnet trough or on the support plates caused idle work undesirable. Especially when an electrodynamic track brake can be built by a juxtaposition of individual brake modules, then the lossless driving on individual currentless connected brake modules is of particular importance. It will happen again and again in practice that not all brake modules are required for each braking operation.
- FIG. 1 shows the electrodynamic track brake installed in a track grid constructed from rails (2) and sleepers (10).
- the base plate (1) of the U-shaped trough body with the running rail (2) via the clamping pieces (3) is clamped.
- the side edges (4) of the U-shaped trough body are bolted to the base plate (1).
- the upper end of the side edges form the outwardly inclined support plates (5) on which the brake beams (6) can move in a transversely bounded by corresponding stops region transverse to the rail longitudinal direction.
- the braking forces acting on the brake beams along the rail are introduced into the inclined support plates (5) by head bolts (7) screwed into the brake beams (6).
- the head bolts move in corresponding oblong holes (across the rail) in the inclined support plates.
- the inclined support plates (5) project beyond the threshold compartment and underlie the brake beams.
- the magnetic field of the electrodynamic brake is generated by the side legs (4) of the U-shaped trough body enclosing coils (8). When energized coils, a magnetic field is generated such that the brake beams have different magnetic polarity. Due to the magnetic forces of attraction, the brake beams are pulled against the wheel and the magnetic circuit is closed.
- the brake beams slide uphill on the inclined support plates.
- the brake bars slide apart on the inclined plates with gravity assistance; the electrodynamic brake thus assumes its release position. Due to the structural design of the U-shaped trough body, the brake can be installed without intervention in the superstructure in an existing track.

Abstract
Description
Die Erfindung betrifft eine elektrodynamische Gleisbremse nach den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to an electrodynamic rail brake according to the features of the preamble of
In Eisenbahnrangieranlagen müssen die unter Ausnützung der Schwerkraft von einem Ablaufberg in die einzelnen Sortier- bzw. Richtungsgleise einlaufenden Güterwagen auf eine definierte, vom Füllungsgrad des aufnehmenden Richtungsgleises abhängige Geschwindigkeit heruntergebremst werden. Hierzu kommen üblicherweise Gleisbremsen zum Einsatz, welche ortsfest am oder im Gleis montiert sind und deren Bremskraft bei jedem ablaufenden Waggon durch eine zentrale Steuerungsinstanz berechnet und eingestellt wird. Elektrodynamische Gleisbremsen stellen hierfür eine bewährte und weit verbreitete Bauform dar. Das funktionale Prinzip der elektrodynamischen Gleisbremse - welche bisweilen auch als Wirbelstrom-Gleisbremse bezeichnet wird - basiert darauf, dass ein im wesentlicher U-förmiger Trog aus ferromagnetischem Material jede Fahrschiene des Gleises von unten her umgreift. Mit Hilfe elektrisch durchflossener Spulen wird in den U-förmigen Trog ein magnetisches Feld induziert, so dass ein offener Magnetkreis entsteht, wobei dann die freien Enden der beiden Schenkel eines U-förmigen Troges magnetische Polflächen bilden. Auf diesen Polflächen sind translatorisch verschiebbare Bremsbalken gelagert. Die Bremsbalken sind dabei so angeordnet, dass die einander gegenüberliegenden Bremsbalken jeweils eine Rille bilden, durch die jedes auf der zugehörigen Fahrschiene rollende Rad eines Schienenfahrzeuges hindurch muss (sog. "Bremsrille"). Sobald ein metallenes Rad eines Schienenfahrzeuges die Bremsrille zwischen den beiden Bremsbalken durchfährt, werden die Bremsbalken durch Einwirken magnetischer Kräfte an das Rad des Schienenfahrzeuges angelegt bzw. angepresst. Durch Einstellen der Stromzufuhr kann somit die auf das Fahrzeugrad einwirkende Bremskraft reguliert werden.In Eisenbahnrangieranlagen the taking advantage of gravity by a runoff mountain in the individual sorting or directional track incoming freight cars must be braked down to a defined, dependent on the degree of filling of the receiving directional track speed. For this purpose, usually rail brakes are used, which are fixedly mounted on or in the track and whose braking force is calculated and adjusted at each departing wagon by a central control authority. Electrodynamic rail brakes are a proven and widespread design for this purpose. The functional principle of the electrodynamic track brake - which is sometimes referred to as eddy current track brake - based on the fact that a substantially U-shaped trough of ferromagnetic material, each rail of the track from below embraces. With the help of electrically through coils, a magnetic field is induced in the U-shaped trough, so that an open magnetic circuit is formed, in which case the free ends of the two legs of a U-shaped trough form magnetic pole faces. On these pole faces translationally movable brake beams are mounted. The brake beams are arranged in such a way that the opposing brake beams each form a groove through which each wheel of a rail vehicle rolling on the associated travel rail must pass (so-called "brake groove"). As soon as a metal wheel of a rail vehicle passes through the brake groove between the two brake beams, the brake beams are applied or pressed against the wheel of the rail vehicle by the action of magnetic forces. By adjusting the power supply, thus, the braking force acting on the vehicle wheel can be regulated.
In der Praxis bereitet die Dimensionierung derartiger elektrodynamischer Gleisbremsen immer wieder Probleme, da die Nennleistung der Bremsanlage natürlich zur sicheren Seite hin und damit für den bremstechnisch ungünstigsten Betriebsfall hin ausgelegt werden muss. Dieser ungünstigste Betriebsfall ist dann zu erwarten wenn bei durchlaufenden Schienenfahrzeugen mit hoher Eingangsgeschwindigkeit (z.B. in Folge eines extrem leicht laufenden Schienenfahrzeuges) eine geringst mögliche Ausgangsgeschwindigkeit (z.B. wegen eines nahezu vollständig belegten Aufnahmegleises und eines damit drastisch verkürzten Restlaufweges) erzielt werden soll und zugleich ungünstige Witterungsbedingungen vorherrschen, die die Reibwerte zwischen Bremsbalken und Fahrzeugrad vermindern.In practice, the dimensioning of such electrodynamic rail brakes always causes problems, since the rated power of the brake system, of course, must be laid out to the safe side and thus for the worst brake operating case. This most unfavorable case of operation is to be expected when in continuous rail vehicles with high input speed (eg as a result of an extremely smooth-running rail vehicle) a lowest possible initial speed (eg because of a nearly fully occupied receiving track and thus drastically shortened residual travel) to be achieved and at the same time unfavorable weather conditions prevail, which reduce the friction between the brake beam and the vehicle wheel.
Bei entsprechender Auslegung einer elektrodynamischen Gleisbremse entstehen großvolumige Baukörper, die hohe elektrische Anschlussleistungen erfordern. Die Magnettröge solcher Anlagen weisen deshalb eine Längserstreckung von mehreren Metern auf, was teilweise erhebliche Schwierigkeiten sowohl bei der Fertigung und der Montage als auch bei der Anlagensteuerung im Betrieb hervorruft. Aus der
Das konstruktive Grundprinzip der elektrodynamischen Gleisbremse, wonach der U-förmige Magnettrog das tragende Bauelement darstellt, in welches die Fahrschiene eingelegt ist, wurde jedoch stets beibehalten. Dies führt nach wie vor dazu, dass elektrodynamische Gleisbremsen sperrige und großvolumige Bauteile darstellen, die nur mit großem oberbautechnischem Aufwand in vorhandene Gleisanlagen eingebaut werden können. Üblicherweise sind beim Einbau derartiger Bremsen in ein bestehendes Gleis eine komplette Demontage des vorhandenen Gleises sowie ein nachfolgender vollständiger Neuaufbau des betroffenen Gleisabschnittes (Gleis auf die geänderte Höhenlage justieren, verschweißen etc...) notwendig.With appropriate design of an electrodynamic rail brake arise bulky structures that require high electrical connection performance. The magnetic troughs of such systems therefore have a longitudinal extent of several meters, which sometimes causes considerable difficulties both in the production and assembly as well as in the plant control in operation. From the
However, the constructive basic principle of the electrodynamic rail brake, according to which the U-shaped magnetic trough is the supporting element, in which the running rail is inserted, has always been maintained. This still leads to electrodynamic rail brakes bulky and bulky components that can be installed only with great technical complexity in existing track systems. Usually, when installing such brakes in an existing track a complete disassembly of the existing track and a subsequent complete rebuild the affected track section (track to the changed altitude adjust, weld, etc ...) is necessary.
Der Erfindung liegt die Aufgabe zugrunde, eine elektrodynamische Gleisbremse bereitzustellen, welche eine gegenüber dem bekannten Stand der Technik einfachere Montage in vorhandenen Gleisanlagen bzw. eine einfachere Wartung der elektrodynamischen Gleisbremse ermöglicht. Insbesondere sollen Teile der Bremsenanlage, vor allem der U-förmige ferromagnetische Eisenkörper, ohne Eingriff in den Oberbau austauschbar sein.The invention has for its object to provide an electrodynamic rail brake, which allows a comparison with the prior art simpler installation in existing track systems or easier maintenance of the electrodynamic rail brake. In particular, parts of the brake system, especially the U-shaped ferromagnetic iron body, without intervention in the superstructure to be interchangeable.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Patentanspruches 1 erfindungsgemäß dadurch gelöst, dass der U-förmige ferromagnetische Trogkörper am Fuß der Fahrschiene hängend befestigt ist.
Dies stellt eine Abkehr vom bisherigen konstruktiven Grundkonzept dar, wonach die Schiene im U-förmigen Trogkörper gleichsam eingebettet gelagert ist. Durch die erfindungsgemäße punktuelle Befestigung wird der Grundstein dafür gelegt, dass die Schiene für Montage- bzw. Demontagearbeiten am Trogkörper nicht mehr über einen längeren Abschnitt gelöst und angehoben bzw. ausgebaut werden muss, sondern es ist nunmehr ein gezieltes Aufweiten der Schwellenfächer, Aufständern der Schienen oder sogar das Ausnutzen der bei Gleisjochen mit definierter Schwellenteilung ohnehin vorgegebenen Breite eines Schwellenfaches möglich. Dies stellt eine deutliche Vereinfachung und Erleichterung der oberbautechnischen Begleitmaßnahmen dar.This object is achieved in conjunction with the preamble of
This represents a departure from the previous constructive basic concept, according to which the rail is stored as it were embedded in the U-shaped trough body. The punctual attachment according to the invention lays the foundation for the fact that the Rail for assembly or disassembly work on the trough body no longer needs to be solved over a longer section and raised or removed, but it is now a targeted widening of thresholds, Aufständern the rails or even taking advantage of the track yokes with a defined threshold division already predetermined width a threshold compartment possible. This represents a significant simplification and facilitation of the technical support measures.
In Ergänzung hierzu sieht das erfinderische Konzept vor, dass die Befestigung des U-förmigen ferromagnetischen Trogkörpers am Fuß der Fahrschiene eine Mehrzahl hakenförmiger Klemmstücke umfasst, welche den Schienenfuß auf seiner Oberseite übergreifen und zugleich mit der Grundplatte des U-förmigen Trogkörpers verschraubbar sind. Diese stellt eine vorteilhafte konstruktive Umsetzung des erfinderischen Konzeptes vor. Die Schraubverbindung ist so ausgeführt, dass die Verschraubung vom Schienenkopf her (also von oben her) eingebracht werden kann.In addition to this, the inventive concept provides that the attachment of the U-shaped ferromagnetic trough body at the foot of the running rail comprises a plurality of hook-shaped clamping pieces which engage over the rail on its upper side and at the same time are screwed to the base plate of the U-shaped trough body. This represents an advantageous constructive implementation of the inventive concept. The screw is designed so that the screw from the rail head ago (ie from above) can be introduced.
Gemäß einer sinnvollen Ausgestaltung ist die elektrodynamische Gleisbremse aus einer Mehrzahl einzelner U-förmiger, jeweils einen Magnettrog bildender ferromagnetischer Trogkörper aufgebaut, welche jeweils an beiden Schenkeln Spulenkörper sowie ein Paar einander gegenüberliegender und auf den Polflächen der Magnettröge verschiebbarer Bremsbalken aufweisen. Das erfinderische Grundprinzip der Aufhängung des U-förmigen Trogkörpers am Schienenfuß ermöglicht erstmals eine Aufteilung der sperrigen, einstückigen Gleisbremse in mehrere einzelne Bremsmodule, die jeweils für sich autark arbeiten und lediglich steuerungstechnisch zu einer Gesamtheit zusammengeschaltet werden. Die einzelnen Module sind jeweils einzeln steuerbar, was zum einen eine Vielzahl möglicher Brems-Szenarien ermöglicht und damit die Flexibilität der Anlage erhöht und zum anderen aber auch die Redundanz und damit Ausfallsicherheit der Anlage erhöht.According to a useful embodiment, the electrodynamic track brake from a plurality of individual U-shaped, each forming a magnetic trough ferromagnetic trough body constructed, each having on both legs bobbin and a pair of opposing and slidable on the pole faces of the magnetic troughs brake beams. The inventive basic principle of the suspension of the U-shaped trough body on the rail allows for the first time a division of the bulky, one-piece track brake in several individual brake modules, each working independently and are interconnected only control technology to form a whole. The individual modules are each individually controllable, which allows for a variety of possible braking scenarios and thus increases the flexibility of the system and on the other hand also increases the redundancy and thus reliability of the system.
Eine besonders sinnvolle Weiterentwicklung der Erfindung ist deshalb darin zu sehen, dass die Abmessungen des U-förmigen ferromagnetischen Trogkörpers in Richtung der Schienenlängsachse kleiner als der freie Abstand zwischen zwei benachbarten Schwellen des Gleisrostes sind. Auf diese Weise können die einzelnen Module der elektrodynamischen Gleisbremse in den Schwellenfächern des vorhandenen Gleisrostes montiert werden. Es ist nunmehr lediglich erforderlich, die Schwellenfächer bis zu einer vorgegebenen Tiefe von Schotter frei zu kehren. Ein Freilegen des Schwellenfaches bis zur Tiefe der Schwellensohle ist jedoch keinesfalls erforderlich. Insbesondere kann somit auch auf das bislang notwendige, umständliche Ausbauen des Gleisjoches nebst anschließender Montage des U-förmigen Trogkörpers sowie das Verlegen und Fixieren der Schienen innerhalb dieser Trogkörper verzichtet werden.A particularly useful development of the invention is therefore to be seen in the fact that the dimensions of the U-shaped ferromagnetic trough body in the direction of the rail longitudinal axis are smaller than the free distance between two adjacent sleepers of the track grid. In this way, the individual modules of the electrodynamic rail brake can be mounted in the threshold compartments of the existing track grid. It is now only necessary to sweep the threshold compartments to a given depth of gravel. However, exposing the threshold compartment to the depth of the sill sole is by no means required. In particular, thus can also be dispensed with the hitherto necessary, cumbersome removal of the track yoke together with subsequent assembly of the U-shaped trough body and the laying and fixing of the rails within this trough body.
Von besonderem Vorteil ist es, wenn Grundplatte und Seitenschenkel des U-förmigen ferromagnetischen Trogkörpers miteinander verschraubbar sind. Auf diese Weise kann der U-förmige Trogkörper in besonders einfacher Weise an der Fahrschiene montiert bzw. von der Fahrschiene demontiert werden. Dies ist nicht zuletzt im Falle etwaiger Reparaturen an der elektrodynamischen Gleisbremse von großem Vorteil.It is particularly advantageous if the base plate and side legs of the U-shaped ferromagnetic trough body can be screwed together. In this way, the U-shaped trough body can be mounted in a particularly simple manner on the running rail or be dismantled from the running rail. This is of great benefit not least in the event of any repairs to the electrodynamic track brake.
Die Erfindung sieht ferner vor, dass jeder Bremsbalken auf einer Trägerplatte verschiebbar gelagert ist. Eine geeignete Auswahl der Materialpaarung zwischen Bremsbalken und Trägerplatte begünstigt das Gleiten der Bremsleisten erheblich und kann die Energie-Effizienz der elektrodynamischen Bremse deutlich verbessern. Selbstverständlich ist auch eine konstruktiv einfachere Lagerung der Bremsbalken auf den Polflächen des Magnettroges denkbar; jedoch geht dies meist mit einer ungünstigeren Materialpaarung und damit höheren Reibungsverlusten einher.The invention further provides that each brake bar is mounted displaceably on a support plate. A suitable selection of the material pairing between the brake beam and carrier plate favors the sliding of the brake strips significantly and can significantly improve the energy efficiency of the electrodynamic brake. Of course, a structurally simpler mounting of the brake beams on the pole faces of the magnetic trough is conceivable; However, this is usually accompanied by a less favorable material pairing and thus higher friction losses.
Gemäss einer sinnvollen Ausgestaltung der Erfindung ist die Abmessung der Trägerplatte und des Bremsbalkens in Richtung der Schienenlängsachse größer als der freie Abstand zwischen zwei benachbarten Schwellen eines Gleisrostes, jedoch zugleich kleiner als das Maß der Schwellenteilung ist. Unter "Schwellenteilung" ist in diesem Kontext der freie Abstand zweier benachbarter Schwellen des Gleisrostes zuzüglich einer Schwellenbreite in Schienenlängsrichtung zu verstehen. Auf diese Weise wird der Einbau zweier elektrodynamischer Gleisbremsen in nebeneinanderliegenden Schwellenfächern ermöglicht. Dadurch wird eine in Schienenlängsrichtung kompakte Bauform mit hinreichend guten Bremseigenschaften erreicht. In Schienenlängsrichtung nebeneinander angeordnete Bremsbalken berühren einander nicht und bleiben somit unabhängig voneinander beweglich.According to a useful embodiment of the invention, the dimension of the support plate and the brake beam in the direction of the rail longitudinal axis is greater than the free distance between two adjacent sleepers of a track grid, but at the same time smaller than the measure of the threshold pitch. In this context, "threshold division" is to be understood as meaning the free distance between two adjacent sleepers of the track grate plus a threshold width in the rail longitudinal direction. In this way, the installation of two electrodynamic rail brakes in adjacent threshold compartments is made possible. As a result, a compact design in the rail longitudinal direction with sufficiently good braking properties is achieved. Brake bars arranged next to one another in the rail longitudinal direction do not touch one another and thus remain movable independently of one another.
Eine besonders wirksame Weiterentwicklung des erfinderischen Gedankens sieht vor, dass mindestens eine Trägerplatte nach außen geneigt ist. Auf diese Weise wird erreicht, dass ein Schienenfahrzeugrad, welches im stromlosen und geschlossenen Zustand der elektrodynamischen Bremse in die von den einander gegenüberliegenden Bremsbalken gebildete Bremsrille einläuft, diese Bremsbalken nicht auseinanderdrücken muss. In bestimmten Anwendungsfällen ist diese durch die Reibung der Bremsbalken auf den Polflächen des Magnettroges bzw. auf den Trägerplatten verursachte Leerlaufarbeit unerwünscht. Gerade wenn eine elektrodynamische Gleisbremse durch eine Aneinanderreihung einzelner Bremsmodule aufgebaut werden kann, dann ist das verlustfreie Befahren einzelner stromlos geschalteter Bremsmodule von besonderer Bedeutung. Es wird in der Praxis immer wieder vorkommen, dass nicht alle Bremsmodule für jeden Bremsvorgang benötigt werden.A particularly effective development of the inventive concept provides that at least one support plate is inclined outwards. In this way, it is achieved that a rail vehicle wheel, which enters the currentless and closed state of the electrodynamic brake in the brake groove formed by the opposing brake beams, these brake beams must not be forced apart. In certain applications, this is due to the friction of the brake beams On the pole faces of the magnet trough or on the support plates caused idle work undesirable. Especially when an electrodynamic track brake can be built by a juxtaposition of individual brake modules, then the lossless driving on individual currentless connected brake modules is of particular importance. It will happen again and again in practice that not all brake modules are required for each braking operation.

Die Figur 1 zeigt die in einen aus Schienen (2) und Schwellen (10) aufgebauten Gleisrost eingebaute elektrodynamische Gleisbremse. Dabei ist die Grundplatte (1) des U-förmigen Trogkörpers mit der Fahrschiene (2) über die Klemmstücke (3) verspannt. Die Seitenflanken (4) des U-förmigen Trogkörpers sind mit dessen Grundplatte (1) verschraubt. Den oberen Abschluss der Seitenflanken bilden die nach außen geneigten Trägerplatten (5), auf denen sich die Bremsbalken (6) in einem durch entsprechende Anschläge begrenzten Bereich quer zur Schienenlängsrichtung gleitend bewegen können. Die längs zur Schiene auf die Bremsbalken wirkenden Bremskräfte werden durch in die Bremsbalken (6) eingeschraubte Kopfbolzen (7) in die geneigten Trägerplatten (5) eingeleitet. Dabei bewegen sich die Kopfbolzen in entsprechenden Langlöchern (quer zur Schiene) in den geneigten Trägerplatten.
Die geneigten Trägerplatten (5) kragen über das Schwellenfach hinaus und unterbauen die Bremsbalken. Das Magnetfeld der elektrodynamischen Bremse wird durch die die Seitenschenkel (4) des U-förmigen Trogkörpers umschließenden Spulen (8) erzeugt.
Bei erregten Spulen wird ein Magnetfeld derart erzeugt, dass die Bremsbalken unterschiedliche magnetische Polung besitzen. Durch die magnetischen Anziehungskräfte werden die Bremsbalken an das Rad herangezogen und der Magnetkreis geschlossen.FIG. 1 shows the electrodynamic track brake installed in a track grid constructed from rails (2) and sleepers (10). In this case, the base plate (1) of the U-shaped trough body with the running rail (2) via the clamping pieces (3) is clamped. The side edges (4) of the U-shaped trough body are bolted to the base plate (1). The upper end of the side edges form the outwardly inclined support plates (5) on which the brake beams (6) can move in a transversely bounded by corresponding stops region transverse to the rail longitudinal direction. The braking forces acting on the brake beams along the rail are introduced into the inclined support plates (5) by head bolts (7) screwed into the brake beams (6). The head bolts move in corresponding oblong holes (across the rail) in the inclined support plates.
The inclined support plates (5) project beyond the threshold compartment and underlie the brake beams. The magnetic field of the electrodynamic brake is generated by the side legs (4) of the U-shaped trough body enclosing coils (8).
When energized coils, a magnetic field is generated such that the brake beams have different magnetic polarity. Due to the magnetic forces of attraction, the brake beams are pulled against the wheel and the magnetic circuit is closed.
Dabei gleiten die Bremsbalken auf den geneigten Trägerplatten bergauf. Bei abgeschaltetem Erregerstrom gleiten die Bremsbalken auf den geneigten Platten mit Schwerkraftunterstützung auseinander; die elektrodynamische Bremse nimmt somit ihre LöseStellung ein.
Durch den konstruktiven Aufbau des U-förmigen Trogkörpers lässt sich die Bremse ohne Eingriff in den Oberbau in ein bestehendes Gleis einbauen.The brake beams slide uphill on the inclined support plates. When the exciter current is switched off, the brake bars slide apart on the inclined plates with gravity assistance; the electrodynamic brake thus assumes its release position.
Due to the structural design of the U-shaped trough body, the brake can be installed without intervention in the superstructure in an existing track.
