Description

Die vorliegende Erfindung betrifft einen Fahrweg eines spurgebundenen Fahrzeuges, insbesondere einer Magnetschwebebahn, mit mehreren hintereinander angeordneten Trägern, wobei jeder Träger eine Fahrwegplatte mit daran angeordneten Führungselementen für das Fahrzeug aufweist und die Fahrwegplatte durch wenigstens einen Steg, der in Längsrichtung des Trägers verläuft und in Einbaulage im wesentlichen nach unten von der Fahrwegplatte absteht, von einem Fundament beabstandet gehalten ist.The present invention relates to a track of a track-bound vehicle, in particular a maglev train, with a plurality of carriers arranged one behind the other, each carrier having a track plate with guide elements for the vehicle arranged thereon and the track plate by at least one web extending in the longitudinal direction of the carrier and in installation position protrudes substantially down from the track plate, is kept spaced from a foundation.

Aus der DE 10 2004 015 495 A1 ist eine Fahrbahn für eine Magnetschwebebahn mit einer Weichenanordnung bekannt, bei welcher Träger Führungselemente für das Fahrzeug aufweisen, welche an einer Fahrwegplatte angeordnet sind. Die Fahrwegplatte ist an einem Steg befestigt, welcher auf einer Einrichtung zur Schwingungsdämpfung angeordnet ist. Die Schwingungsdämpfung wird bei dieser Ausführung vorgesehen, um einen ruhigen Fahrbetrieb des Fahrzeuges in der Weiche zu erlauben. Der Träger ist hierfür direkt auf der Schwingungsdämpfungseinrichtung befestigt. Nachteilig ist hierbei, dass der Träger gerade in der Weiche sehr filigran ausgebildet sein muss, um die Biegung für eine Weichenschaltung zu erlauben. Darüber hinaus müssen aufeinanderfolgende Träger miteinander fest verbund en sein, um vertikale Absätze beim Einfedern einzelner Trägem während der Überfahrt des Fahrzeuges und um Stöße zwischen dem bereits eingefederten und dem noch nicht eingefederten nachfolgenden Träger zu vermeiden. Durch die Verbindung der Träger miteinander können Probleme bei der Längenausdehnung der Träger entstehen.From the DE 10 2004 015 495 A1 is a carriageway for a maglev train with a switch assembly known in which carrier guide elements for the vehicle, which are arranged on a track plate. The track plate is attached to a web which is arranged on a device for vibration damping. The vibration damping is provided in this embodiment, to allow a smooth driving operation of the vehicle in the switch. The carrier is for this purpose mounted directly on the vibration damping device. The disadvantage here is that the carrier must be very filigree just in the switch to allow the bend for a switch circuit. In addition, successive carriers must be firmly together with each other in order to avoid vertical heels during compression of individual carriers during the passage of the vehicle and to shocks between the already sprung and the not yet deflected subsequent carrier. By connecting the carriers together, problems can arise in the longitudinal expansion of the carrier.

Aus der WO 2004/022852 A1 ist ebenfalls eine Fahrbahn für Magnetbahnzüge bekannt. Eine Fahrwegplatte mit daran angeordneten Führungselementen für das Fahrzeug ist mittels Federlagern auf einem Betonträger befestigt. Nachteilig ist das unterschiedliche Einfedern benachbarter Fahrwegplatten während der Überfahrt eines Fahrzeuges, wenn die Fahrwegplatten nicht fest miteinander verbunden sind. Darüber hinaus kommt bei dieser Ausführung noch hinzu, dass durch die geringe Masse der Fahrwegplatten ein hierdurch bewirktes ungünstiges Masse-Feder-System erzeugt wird, welches eine Schwingungsdämpfung nur unzureichend bewirken kann.From the WO 2004/022852 A1 is also known as a track for maglev trains. A track plate with guide elements arranged thereon for the vehicle is mounted by spring bearings on a concrete beam. A disadvantage is the different compression of adjacent track plates during the passage of a vehicle when the track plates are not firmly connected. In addition, in this embodiment is added that the resulting low unfavorable mass-spring system is generated by the low mass of the track plates, which can cause insufficient vibration damping.

Aus der DE 103 21 047 A1 ist ein gattungsgemäßen Fahrweg mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt.From the DE 103 21 047 A1 is a generic track with the features of the preamble of claim 1 known.

Aufgabe der vorliegenden Erfindung ist es somit, einen Fahrweg zu schaffen, bei welchem benachbarte Träger gleichmäßig einfedern und somit Stöße zwischen benachbarten Trägern während der Überfahrt eines Fahrzeuges vermieden werden, unabhängig davon, ob die Träger miteinander verbunden sind oder nicht. Darüber hinaus soll ein wirkungsvolles Masse-Feder-System geschaffen werden, bei welchem eine sehr gute Schwingungsdämpfung erzeugt werden kann.Object of the present invention is therefore to provide a track in which adjacent carrier compress evenly and thus shocks between adjacent carriers are avoided during the passage of a vehicle, regardless of whether the carriers are connected together or not. In addition, an effective mass-spring system is to be created, in which a very good vibration damping can be generated.

Die Aufgabe wird gelöst mit einem Fahrweg mit den Merkmalen des Patentanspruches 1.The object is achieved with a track with the features of claim 1.

Erfindungsgemäß ist der Fahrweg, welcher eine Fahrwegplatte und einen Steg aufweist, auf einem Fundament befestigt, welches in vertikaler Richtung federnd auf dem Untergrund gelagert ist. Als Masse für das Masse-Feder-System dient somit nicht nur das Gewicht des Trägers, sondern darüber hinaus auch die Masse des Fundaments. Je nach Bedarf und unabhängig von der Gestaltung des Trägers, kann das Fundament hinsichtlich seiner Masse derart ausgebildet sein, dass es eine zuverlässige Schwingungsdämpfung erzeugt. Es wird hierdurch ein System geschaffen, welches einen ruhigen und komfortablen Betrieb eines Fahrzeuges, insbesondere einer Magnetschwebebahn, auf dem Träger des Fahrweges erlaubt.According to the invention, the guideway, which has a guideway plate and a web, is mounted on a foundation, which is mounted resiliently on the ground in the vertical direction. As mass for the mass-spring system thus not only the weight of the carrier, but also serves the mass of the foundation. Depending on requirements and regardless of the design of the carrier, the foundation can be designed in terms of its mass so that it generates a reliable vibration damping. It is thereby created a system which allows a quiet and comfortable operation of a vehicle, in particular a maglev, on the support of the track.

Zudem befinden sich mindestens zwei Träger auf einem einzigen Fundament, so dass diese zusammen mit dem Fundament bei einer Überfahrt ein federn. Ein Absatz oder ein unzulässiger Knick zwischen zwei aufeinanderfolgenden Trägern wird hierdurch vermieden. Beide Träger bewegen sich gleichermaßen zusammen mit dem Fundament und bilden somit einen kontinuierlichen Fahrweg. Darüber hinaus besteht der Vorteil, dass auch hierdurch die Masse des Masse-Feder-Systems weiter vergrößert wurde, da auch das Gewicht des nachfolgenden Trägers das Schwingsystem beeinflusst. Auf diese Weise wird ein besonders vorteilhaftes und günstiges Masse-Feder-System für die Lagerung der Fahrwegträger erzielt. Dies ist besonders dann von Vorteil, wenn es sich bei dem Fundament um ein diskontinuierlich ausgeführtes Fundament handelt, da hierdurch die Masse des Fundaments nicht so groß ist wie bei dem kontinuierlich ausgeführten Fundament.In addition, there are at least two carriers on a single foundation so that they spring together with the foundation in a crossing. A paragraph or an impermissible kink between two consecutive straps is thereby avoided. Both beams move equally together with the foundation and thus form a continuous track. In addition, there is the advantage that this also the mass of the mass-spring system has been further increased, as well as the weight of the following carrier influences the vibrating system. In this way, a particularly advantageous and favorable mass-spring system for the storage of guideway beams is achieved. This is particularly advantageous when the foundation is a discontinuous foundation, as this does not make the mass of the foundation as large as in the continuously running foundation.

Um eine lagegenaue, individuelle Aufstellung der einzelnen Träger entsprechend dem geforderten Verlauf der Fahrwegtrasse zu ermöglichen, ist es vorteilhaft, wenn zwischen Träger und Fundament ein Lagersockel angeordnet ist und der Träger zusammen mit dem Lagersockel auf dem Fundament angeordnet ist. Der Lagersockel kann hierbei so ausgeführt sein, dass der Träger horizontal ausgerichtet ist. Es kann aber auch insbesondere für Kurvenverläufe ein trapez- oder keilförmiger Lagersockel eingesetzt werden, so dass ein an sich gerade ausgebildeter Träger geneigt eingebaut wird. Der Lagersockel kann dabei einteilig mit dem Fundament ausgebildet sein. Es ist aber auch möglich, dass der Lagersockel als separates Bauteil hergestellt und mit dem Fundament fest verbunden wird. Auf dem Lagersockel wird sodann der Träger befestigt, d. h. insbesondere angeschraubt. Die Masse des Masse-Feder-Systems wird durch den Lagersockel weiter vergrößert. Alternativ kann der Träger auch direkt, ohne Lagersockel, auf dem Fundament mit Auflage und Haltevorrichtungen angeordnet sein.In order to enable a positionally accurate, individual listing of the individual carriers according to the required course of the route, it is advantageous if between the support and the foundation, a bearing base is arranged and the carrier is arranged together with the bearing base on the foundation. The bearing base can in this case be designed so that the carrier is aligned horizontally. But it can also be used in particular for curves a trapezoidal or wedge-shaped bearing base, so that a straight trained himself carrier is installed inclined. The bearing base can be formed integrally with the foundation. But it is also possible that the bearing base is made as a separate component and firmly connected to the foundation. On the bearing base of the carrier is then attached, ie in particular screwed. The mass of the mass-spring system is further increased by the bearing base. Alternatively, the carrier can also be arranged directly, without a bearing base, on the foundation with support and holding devices.

Um ein besonders vorteilhaftes Masse-Feder-System zu schaffen, welches insbesondere auch eine gewisse Dämpfung bei Beschleunigungs- oder Bremsmanövern des Fahrzeuges bewirkt, kann vorgesehen sein, dass das Fundament nicht nur in vertikaler, sondern auch in horizontaler Richtung fedemd auf dem Untergrund gelagert ist. Die horizontale elastische Abstützung kann sowohl in Längsrichtung des Trägers als auch in seiner Querrichtung ausgeführt sein. Damit werden auch seitlich auftretenden Stöße gedämpft.In order to provide a particularly advantageous mass-spring system, which in particular also causes a certain damping during acceleration or braking maneuvers of the vehicle, it can be provided that the foundation is mounted not only in the vertical, but also in the horizontal direction fedemd on the ground , The horizontal elastic support can be designed both in the longitudinal direction of the carrier and in its transverse direction. This also attenuates laterally occurring shocks.

Eine federnde Unterlage zwischen Fundament und Untergrund kann kontinuierlich oder diskontinuierlich ausgebildet sein. Je nach verwendetem Material der Unterlage ist die vorteilhaftere Lösung zu wählen.A resilient base between the foundation and the substrate can be continuous or discontinuous. Depending on the used material of the pad, the more advantageous solution is to be chosen.

Das Fundament kann verschieden ausgeführt sein. So ist entweder ein kontinuierlicher Verlauf des Fundaments oder ein diskontinuierlicher Verlauf des Fundaments möglich. Bei einem kontinuierlichen Verlauf des Fundaments ist unterhalb des Trägers eine durchgehende Platte, insbesondere aus Beton, vorhanden, welche federnd gelagert ist. Hierdurch entsteht eine besonders große gefederte Masse. Allerdings ist der Aufwand der Herstellung eines derartigen Fundaments auch relativ groß, da große Bauteillängen federnd gelagert werden müssen. Bei einer diskontinuierlichen Ausbildung des Fundaments ist es ausreichend, wenn ein örtlich begrenzter Bereich unterhalb der Befestigungsstellen des Trägers auf dem Fundament federnd gelagert ist. Das Fundament ist auch auf diese Bereiche begrenzt, so dass die Herstellung kostengünstiger durchgeführt werden kann.The foundation can be designed differently. Thus, either a continuous course of the foundation or a discontinuous course of the foundation is possible. In a continuous course of the foundation, a continuous plate, in particular of concrete, is present below the carrier, which is spring-mounted. This creates a particularly large spring-loaded mass. However, the hassle of making a Such foundation also relatively large, since large component lengths must be resiliently mounted. In a discontinuous design of the foundation, it is sufficient if a localized area is resiliently mounted below the attachment points of the carrier on the foundation. The foundation is also limited to these areas, so that the production can be carried out more cheaply.

Ist das Fundament in einem Trog des Untergrundes angeordnet, so ist insbesondere die Führung des Fundaments beim Einfedern und ganz besonders die Anordnung für die horizontale Einfederung des Fundaments vorteilhaft auszuführen. Die Trogwände dienen dabei insbesondere zur Abstützung der horizontalen Federungen.If the foundation is arranged in a trough of the ground, in particular the guidance of the foundation during compression and in particular the arrangement for the horizontal deflection of the foundation is to be carried out advantageously. The trough walls serve in particular to support the horizontal suspension.

Das erfindungsgemäße System der Fahrweglagerung eignet sich besonders gut für die Anwendung in einem Tunnel. Der Untergrund ist hierbei die Tunnelsohle. Schwingungen des Systems bei der Überfahrt eines Fahrzeuges übertragen sich hierdurch nicht oder nur unbedeutend auf die Tunnelröhre und die weitere Umgebung.The inventive system of track storage is particularly well suited for use in a tunnel. The underground is here the tunnel sole. Oscillations of the system during the passage of a vehicle are thereby not or only insignificantly transmitted to the tunnel tube and the wider environment.

Vorteilhafterweise ist der Träger ein Standardbauteil und Überhöhungen des Fahrweges in einem Kurvenverlauf erfolgen mittels einer keilförmigen Gestaltung des Lagersockels und/oder des Fundaments. Es ist damit eine wirtschaftliche Herstellung des Fahrweges ermöglicht.Advantageously, the carrier is a standard component and elevations of the track in a curve made by means of a wedge-shaped design of the bearing pedestal and / or the foundation. It is thus an economical production of the track allows.

Insbesondere bei einer Ausführung, bei welcher der Lagersockel unabhängig von dem Fundament hergestellt wurde, ist es vorteilhaft, wenn der Lagersokkel auf dem Fundament justiert ist. Die Verbindung zwischen Träger und Lagersockel erfolgt hierdurch beispielsweise mit einer einfachen Schraubverbindung. Die genaue Ausrichtung des Trägers wird durch Justiereinrichtungen, welche sich im Lagersockel in Bezug auf das Fundament befinden, durchgeführt. Nach dem Justieren des Fundaments wird eine zwischen Lagersockel und Fundament befindliche Vergussfuge mit Vergussmörtel ausgefüllt und die Justierung hierdurch fixiert. Die Verbindung zwischen Lagersockel und Fundament kann auch mittels einer Anschlußbewehrung erfolgen um eine schubfeste Verbindung zu erhalten.In particular, in an embodiment in which the bearing pedestal was made independently of the foundation, it is advantageous if the Lagersokkel is adjusted to the foundation. The connection between the carrier and bearing base takes place hereby, for example, with a simple screw. The exact alignment of the carrier is performed by adjusting means, which are located in the bearing base with respect to the foundation. After adjusting the foundation, a grouting joint between the bearing pedestal and the foundation is filled with grouting mortar and the adjustment is thereby fixed. The connection between the bearing base and foundation can also be done by means of a connection reinforcement to obtain a shear-resistant connection.

Durch die erfindungsgemäße Lagerung der Träger, wenn zwei Träger an ihren benachbarten Enden auf einem einzigen Fundament angeordnet sind, ist es möglich, dass die Träger nicht direkt miteinander verbunden sind. Zwischen den beiden Trägem kann ein Dehnungsspalt erhalten bleiben. Längenausdehnungen der Träger können hierdurch problemlos erfolgen, ohne dass es zu großen Verspannungen innerhalb des Fahrweges kommt. Insbesondere durch die gemeinsame Lagerung zweier benachbarter Träger auf einem Fundament erfolgt auch ein gemeinsames Einfedern der Träger bei einer Überfahrt eines Fahrzeuges, so dass eine direkte Verbindung der beiden Träger miteinander nicht erforderlich ist.Due to the inventive mounting of the carrier, when two carriers are arranged at their adjacent ends on a single foundation, it is possible that the carriers are not directly connected to each other. An expansion gap can be maintained between the two carriers. Length expansions of the carrier can thereby be done easily, without causing great tension within the track. In particular, by the common storage of two adjacent carrier on a foundation also occurs a common compression of the carrier in a crossing of a vehicle, so that a direct connection of the two carriers is not required with each other.

Um einen Winkelversatz bzw. leichten Knick des Fahrweges an zwei benachbarten Trägern in einem geringen zulässigen Maß zu erlauben, ist es vorteilhaft, wenn der Träger auf dem Lagersockel bzw. auf dem Fundament mit einem einen Winkelversatz zulassenden Lager befestigt ist. Hierdurch ist die Längenausdehnung der Träger und das Einfedern zweier Träger in einem geringen Maß möglich. Im Gegensatz zu einem Höhenversatz der beiden benachbarten Träger, ist dieses winkelige Einknicken der beiden Träger zueinander zulässig. Der Fahrbetrieb wird nicht behindert.In order to allow an angular offset or slight bend of the track on two adjacent carriers to a small permissible extent, it is advantageous if the carrier is mounted on the bearing pedestal or on the foundation with an angle offset permitting bearing. This is the length expansion of the carrier and the compression of two carriers in a small degree possible. In contrast to a height offset of the two adjacent carrier, this angular buckling of the two carriers is permissible to each other. The driving is not hindered.

Die Träger, welche in dem erfindungsgemäßen Fahrweg eingesetzt werden, sind vorzugsweise aus Betonfertigteilen hergestellt. Auch das Fundament kann als Betonfertigteil oder als Ortbetonteil ausgeführt sein. Selbstverständlich sind auch andere Träger möglich, bei welchen diese aus Stahl oder kombiniert aus Stahl und Beton gefertigt sind. Der Träger kann einteilig oder mehrteilig beispielsweise mit an der Fahrwegplatte befestigten separaten Stegen ausgeführt sein. Durch den erfindungsgemäßen Aufbau des Fahrweges mit einem federnd gelagerten Fundament auf dem die Träger angeordnet sind, können auch leichte Trägerausführungen optimal hinsichtlich des Masse-Feder-Systems gestaltet werden.The carriers, which are used in the track according to the invention, are preferably made of precast concrete parts. Also, the foundation can be designed as precast concrete or in-situ concrete part. Of course, other carriers are possible in which these are made of steel or combined steel and concrete. The carrier may be made in one or more parts, for example, with attached to the track plate separate webs. The inventive structure of the track with a spring-mounted foundation on which the carrier are arranged, even lightweight carrier versions can be optimally designed with respect to the mass-spring system.

Bei einer besonderen Bauausführung ist der Träger kontinuierlich auf dem Fundament aufgelagert. Es ergibt sich damit eine gleichmäßige Belastungscharakteristik des Trägers.In a special construction, the carrier is continuously supported on the foundation. This results in a uniform load characteristics of the carrier.

Figur 1 zeigt einen Querschnitt durch einen Tunnel 1, in welchem ein Fahrweg 2 mit einem Träger 3 angeordnet ist. Der Fahrweg 2 ist in dem vorliegenden Ausführungsbeispiel für ein Fahrzeug einer Magnetschwebebahn vorgesehen. Er kann aber auch beispielsweise für eine Eisenbahn vorgesehen sein. Der Träger 3 weist eine Fahrwegplatte 4 auf, an deren seitlichen Rändern Führungselemente 5 für das Fahrzeug befestigt sind. Die Führungselemente dienen sowohl der seitlichen Führung des Fahrzeuges als auch für dessen Antrieb. An der Fahrwegplatte 4 sind Stege 6 angeordnet, welche die Fahrwegplatte 4 von einem Lagersockel 7 und einem Fundament 8 beabstandet hält. Der Träger 3 ist auf dem Lagersockel 7 fest angeordnet. Alternativ kann aber bereits hier eine gewisse Elastizität vorhanden sein, um einen Bewegung des Trägers 3 auf dem Lagersockel 7 in geringem Umfang zuzulassen. Der Lagersockel 7 ist mit dem Fundament 8 fest verbunden. Er kann separat von dem Fundament 8 hergestellt sein. In Ausführungsvarianten ist es jedoch auch möglich, dass der Lagersockel 7 einteilig mit dem Fundament 8 oder den Stegen 6 ausgeführt ist. FIG. 1 shows a cross section through a tunnel 1, in which a track 2 with a support 3 is arranged. The guideway 2 is provided in the present embodiment for a vehicle of a magnetic levitation railway. But it can also be provided for example for a railway. The carrier 3 has a track plate 4, on the lateral edges of which guide elements 5 are fastened to the vehicle. The guide elements serve both the lateral guidance of the vehicle and for its drive. At the track plate 4 webs 6 are arranged, which holds the track plate 4 spaced from a bearing pedestal 7 and a foundation 8. The carrier 3 is fixedly arranged on the bearing pedestal 7. Alternatively, however, a certain elasticity may already be present here in order to allow a slight movement of the carrier 3 on the bearing pedestal 7. The bearing base 7 is fixedly connected to the foundation 8. It can be made separately from the foundation 8. In embodiments, however, it is also possible that the bearing pedestal 7 is made in one piece with the foundation 8 or the webs 6.

Eine Sohle 9 des Tunnels 1 weist einen Trog 10 auf, in welchem das Fundament 8 federnd gelagert ist. Hierfür sind Federelemente 11 und 12 vorgesehen, auf welchen sich das Fundament 8 abstützt. Die Federelemente 11 dienen hierfür für das Einfedern in vertikaler Richtung, während die Federelemente 12 ein Einfedern in horizontaler seitlicher Richtung erlauben. Bei einer nicht dargestellten Ausführungsform der Erfindung sind nur Federelemente 11 vorhanden, so dass nur ein Einfedern in vertikaler Richtung erfolgt.A sole 9 of the tunnel 1 has a trough 10, in which the foundation 8 is spring-mounted. For this purpose, spring elements 11 and 12 are provided, on which the foundation 8 is supported. The spring elements 11 serve for this purpose for compression in the vertical direction, while the spring elements 12 allow compression in the horizontal lateral direction. In an embodiment of the invention, not shown, only spring elements 11 are present, so that only a compression takes place in the vertical direction.

Der gesamte Fahrweg 2 ist somit auf dem Fundament 8 gelagert, welches elastisch sowohl in vertikaler als auch in horizontaler seitlicher Richtung abgestützt ist. Hierdurch entsteht ein Masse-Feder-System mit einer außerordentlich großen Masse, welche eine Schwingungsdämpfung bewirkt, die eine äußerst ruhige und für das Fahrzeug, die Insassen und das Bauwerk schonende Überfahrt erlauben. Außerdem werden Erschütterungen gegenüber der Umgebung gedämpft, was insbesondere eine Bauwerksschonung bedeutet.The entire track 2 is thus mounted on the foundation 8, which is elastically supported in both the vertical and in the horizontal lateral direction. This creates a mass-spring system with an extraordinarily large mass, which causes a vibration damping, the one extremely quiet and for the vehicle, the occupants and the building gentle crossing allow. In addition, vibrations are attenuated to the environment, which means in particular a building conservation.

In dem vorliegenden Ausführungsbeispiel der Figur 1 ist der Lagersockel 7 keilförmig ausgebildet. Dies wird der Fall sein, wenn der Fahrweg 2 in einer Kurve verlegt ist. Durch den keilförmigen Lagersockel 7 entsteht eine Überhöhung des Trägers 3, wodurch die Belastung auf das Fahrzeug bei der Kurvenfahrt reduziert wird. Selbstverständlich kann der Lagersockel 7 auch derart ausgeführt sein, dass der Träger 3 gerade, ohne Überhöhung, verläuft.In the present embodiment of the FIG. 1 the bearing base 7 is wedge-shaped. This will be the case when the track 2 is laid in a curve. By the wedge-shaped bearing base 7 creates an elevation of the carrier 3, whereby the load on the vehicle is reduced when cornering. Of course, the bearing base 7 can also be designed such that the carrier 3 straight, without elevation, runs.

Figur 2 zeigt ein ähnliches Ausführungsbeispiel wie in Figur 1. Unterschiedlich ist hierbei lediglich, dass der Träger 3 direkt auf dem Fundament 8 befestigt ist. Auf den Lagersockel 7 wurde verzichtet. Auch eine derartige Ausführung bewirkt ein sehr gut wirkendes Masse-Feder-System. Insbesondere bei geraden Strecken kann dies eine vorteilhafte und kostengünstige Bauausführung der Erfindung sein. Die Befestigung des Trägers 3 auf dem Fundament 8 kann entweder starr oder auch seinerseits elastisch sein. Auch die Befestigung nach Art eines Festlagers und eines Loslagers ist hier ebenso wie bei der Ausführung nach Figur 1 möglich, um Längendehnungen des Trägers 3 zu gestatten. FIG. 2 shows a similar embodiment as in FIG. 1 , The only difference is that the carrier 3 is mounted directly on the foundation 8. On the bearing base 7 has been omitted. Such a design causes a very good acting mass-spring system. Especially with straight lines, this can be an advantageous and cost effective construction of the invention. The attachment of the carrier 3 on the foundation 8 can be either rigid or elastic in turn. The attachment in the manner of a fixed bearing and a floating bearing is here as well as in the execution FIG. 1 possible to allow elongation of the carrier 3.

Figur 3 zeigt eine Seitenansicht eines Ausschnittes aus einem Fahrweg 2 mit zwei Trägern 3. Aus der Darstellung der Figur 3 ist zu entnehmen, dass zwei Träger 3 an den einander benachbarten Enden auf einem Fundament 8 gelagert sind. Das Fundament 8 ist seinerseits wiederum mit Federelementen 11 in vertikaler Richtung gegenüber einem Untergrund 13 gelagert. In horizontaler Richtung befinden sich Federelemente 12', welche eine federnde Abstützung des Fundamentes 8 in horizontaler Richtung, hier im Gegensatz zu den Figuren 1 und 2, jedoch in Längsrichtung des Trägers 3 bewirken. FIG. 3 shows a side view of a section of a track 2 with two carriers 3. From the illustration of FIG. 3 It can be seen that two carriers 3 are mounted at the adjacent ends on a foundation 8. The foundation 8 is in turn mounted with spring elements 11 in the vertical direction relative to a substrate 13. In the horizontal direction are spring elements 12 ', which a resilient support of the foundation 8 in the horizontal direction, here in contrast to the Figures 1 and 2 , but effect in the longitudinal direction of the carrier 3.

Darüber hinaus können die Federelemente 12 aus den Figuren 1 und 2 auch hier für eine seitliche Abstützung sorgen.In addition, the spring elements 12 of the Figures 1 and 2 here too provide lateral support.

Die beiden Träger 3 müssen nicht miteinander fest verbunden sein. Durch die gemeinsame Lagerung auf einem Fundament 8 bewirken sie ein gemeinsames Einfedem, so dass ein unzulässiger Höhenversatz der beiden benachbarten Träger 3 bei einer Überfahrt eines Fahrzeuges nicht erfolgt.The two carriers 3 need not be firmly connected. By the common storage on a foundation 8 they cause a common compression, so that an inadmissible height offset of the two adjacent carrier 3 does not occur when crossing a vehicle.

Wie aus Figur 3 zu entnehmen ist, sind die Träger 3 auf mehreren Fundamenten 8 diskontinuierlich gelagert. Jeder Träger 3 ist an dem Ende, an dem er mit dem nächsten Träger 3 benachbart ist, auf einer einzigen Fundamentplatte 8 gelagert. Das andere Ende des Trägers 3 ist auf einer anderen Fundamentplatte 8 gelagert, welche mit dem anderen benachbarten Träger 3 zusammenwirkt.How out FIG. 3 can be seen, the carrier 3 are stored on several foundations 8 discontinuously. Each carrier 3 is supported on a single base plate 8 at the end adjacent to the next carrier 3. The other end of the carrier 3 is mounted on another base plate 8, which cooperates with the other adjacent carrier 3.

Um die horizontale Einfederung zu ermöglichen, ist das Fundament 8 mit seinen Federelementen 12' gegenüber Höckern 14 abgestützt, welche auf dem Untergrund 13 befestigt sind. Die Höcker 14 erlauben die Aufnahme von Kräften, welche beispielsweise durch das Fahrzeug beim Abbremsen oder Beschleunigen in horizontaler Längsrichtung der Träger auftreten. Bei einer seitlichen Lagerung der Fundamente 8 können auch hierfür entsprechende Höcker vorgesehen sein.In order to enable the horizontal deflection, the foundation 8 is supported with its spring elements 12 'opposite bumps 14 which are mounted on the substrate 13. The bumps 14 allow the absorption of forces, which occur for example by the vehicle when braking or accelerating in the horizontal longitudinal direction of the carrier. In a lateral support of the foundations 8 corresponding humps may also be provided for this purpose.

Figur 4 zeigt ein ähnliches Ausführungsbeispiel der Erfindung wie in Figur 3. Unterschiedlich ist hierbei lediglich, dass die Träger 3 nicht diskontinuierlich gelagert sind, sondern vielmehr kontinuierlich auf einem einzigen Fundament 8'. Das Fundament 8' verläuft unterhalb der Träger 3 und ist gegenüber dem Untergrund 13 mit einer Vielzahl von Federelementen 11 abgestützt. Es entsteht hierdurch eine außerordentlich große Masse für das Masse-Feder-System, welche eine besonders gute Schwingungsdämpfung erzeugt. Nachteile gegenüber der Ausführung gemäß Figur 3 kann allerdings der höhere Bauaufwand sein. FIG. 4 shows a similar embodiment of the invention as in FIG. 3 , The only difference here is that the carriers 3 are not stored discontinuously, but rather continuously on a single foundation 8 '. The foundation 8 'extends below the carrier 3 and is supported relative to the substrate 13 with a plurality of spring elements 11. This results in an extremely large mass for the mass-spring system, which produces a particularly good vibration damping. Disadvantages over the execution according to FIG. 3 However, this can be the higher construction cost.

Die vorliegende Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Änderungen im Rahmen der Patentansprüche sind jederzeit möglich.The present invention is not limited to the illustrated embodiments. Changes within the scope of the claims are possible at any time.
