Anschließend wird der Motor noch über einfache Schraubverbindungen (unter anderem auch im Bereich der Formschlussverbindung) reibschlüssig mit dem Drehgestellrahmen verbunden, um eine vibrationsfeste Verbindung zu erzielen.Such a design is often applied to bogies of rail vehicles their application to attach a traction motor to the bogie frame.

Demontage um einen erheblichen Querweg (quer zu der Höhenrichtung) verschoben werden muss, um den Tragarm des Motors (in der Höhenrichtung von unten) an dem Vorsprung am Drehgestellrahmen vorbeiführen zu können, in den er dann (von oben) eingehängt werden soll. Hierfür steht in modernen Drehgestellen wegen der Vielzahl von dort untergebrachten Komponenten in der Regel nur sehr wenig Platz zur Verfügung, sodass der für die Montage bzw. Demontage des Motors entlang des Montagepfades freizuhaltende Raum (Montagekanal) zum einen das Bauraumproblem noch weiter verschärft. Zudem ist es von Nachteil, dass dieser für die Montage bzw. Demontage des Motors freizuhaltende Raum in großen Teilen nur während der Montage bzw. Demontage des Motors benötigt wird, während er zu anderen Zeiten ungenutzt ist.The mounting of the motor from above into the bogie frame, however, has the disadvantage that the motor during assembly or disassembly by a considerable transverse travel (transverse to the height direction) must be moved to the arm of the engine (in the height direction from below) to be able to lead past the projection on the bogie frame, in which it should then be suspended (from above). For this is in modern bogies due to the large number of components housed there usually only very little space available, so to be kept free for the assembly and disassembly of the motor along the mounting path space (mounting channel) on the one hand further aggravates the space problem. In addition, it is disadvantageous that this space to be kept free for the assembly or disassembly of the engine is required in large parts only during the assembly or disassembly of the engine, while it is unused at other times.

Ein Beispiel vom nächstliegenden Stand der Technik stellt die US 2 330 912 A dar.An example of the closest prior art is the US 2,330,912A represents.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, eine Fahrwerkseinheit bzw. ein Montageverfahren der eingangs genannten Art zur Verfügung zu stellen, welche bzw. welches die oben genannten Nachteile nicht oder zumindest in geringerem Maße aufweist und insbesondere bei einfacher Gestaltung einen einfachen Einbau der Fahrmotoreinheit auf engstem Raum ermöglicht.The present invention is therefore based on the object to provide a suspension unit or a mounting method of the type mentioned which or which does not have the disadvantages mentioned above or at least to a lesser extent and in particular with a simple design a simple installation of the drive motor unit in a confined space.

Die vorliegende Erfindung löst diese Aufgabe ausgehend von einer Fahrwerkseinheit gemäß dem Oberbegriff des Anspruchs 1 durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. Sie löst diese Aufgabe weiterhin ausgehend von einem Verfahren gemäß dem Oberbegriff des Anspruchs 13 durch die im kennzeichnenden Teil des
Anspruchs 13 angegebenen Merkmale.The present invention solves this problem starting from a chassis unit according to the preamble of claim 1 by the features stated in the characterizing part of claim 1. It solves this problem further starting from a method according to the preamble of claim 13 by the in the characterizing part of
Claim 13 specified characteristics.

Der vorliegenden Erfindung liegt die technische Lehre zu Grunde, dass man bei einfacher Gestaltung einen einfachen Einbau der Fahrmotoreinheit auf engstem Raum ermöglicht, wenn für die Fixierung bzw. Abstützung der Fahrmotoreinheit wenigstens ein Befestigungselement verwendet wird, das mit der Motorhalteeinrichtung und der Fahrmotoreinheit jeweils über einen Formschluss zusammenwirkt und in einer quer zur Montagerichtung verlaufenden Verriegelungsrichtung erst dann zwischen die Motorhalteeinrichtung und die Fahrmotoreinheit eingesetzt wird, wenn sich diese bereits im Bereich ihrer Stützposition befindet.The present invention is based on the technical teaching that, with a simple design, a simple installation of the traction motor unit in a confined space allows, if at least one fastening element is used for the fixation or support of the drive motor unit with the motor holding device and the traction motor unit each via a Positive locking cooperates and is used in a direction transverse to the mounting direction locking direction between the motor holding device and the traction motor unit only when it is already in the region of its support position.

Das Befestigungselement kann hierbei im montierten Zustand mit anderen Worten den Vorsprung an der Motorhalteeinrichtung bilden, in den die Fahrmotoreinheit (formschlüssig) eingehängt wird, um wie bei den bekannten Gestaltungen eine verliersichere Fixierung des Motors zu erzielen. Andererseits kann das im montierten Zustand den Vorsprung an der Motorhalteeinrichtung bildende Befestigungselement während der Bewegung der Fahrmotoreinheit in den Bereich ihrer Stützposition (anders als bei den bekannten Gestaltungen) aus dem Bewegungsraum der Fahrmotoreinheit entfernt sein, sodass die Fahrmotoreinheit auf kürzestem Wege und zumindest ohne größere Ausweichbewegungen (z. B. um den Vorsprung an der Motorhalteeinrichtung herum) in ihre Stützposition bewegt werden kann.In this case, the fastening element can in other words form the projection on the motor holding device in the mounted state, in which the traction motor unit is mounted (positively locking), as in the known designs a captive fixation of the To achieve motors. On the other hand, during the movement of the traction motor unit in the region of its supporting position (unlike the known designs), the fastening element forming the projection on the motor holding device can be removed from the travel space of the traction motor unit, so that the traction motor unit can be moved by the shortest route and at least without major evasive movements (For example, around the projection on the motor holding device around) can be moved to its supporting position.

Für die Montage bzw. Demontage der Fahrmotoreinheit ist entlang ihres Montagepfades somit nur ein minimaler (durch die Abmessungen der Fahrmotoreinheit vorgegebener) Montagekanal freizuhalten, wodurch sich das Bauraumproblem in der Fahrwerkseinheit entschärft. Zudem verringert sich wegen der zumindest weitgehenden Vermeidung von Ausweichbewegungen bei der Montage bzw. Demontage der Fahrmotoreinheit die Komplexität der Montagebewegung, sodass sich die Montage bzw. Demontage entsprechend vereinfacht. Im einfachsten Fall kann lediglich eine einzige geradlinige Bewegung ausreichen.For assembly or disassembly of the traction motor unit, only a minimal (predetermined by the dimensions of the traction motor unit) mounting channel is therefore to be kept free along its mounting path, whereby the installation space problem in the suspension unit defused. In addition, due to the at least largely avoiding evasive movements during assembly or disassembly of the drive motor unit, the complexity of the assembly movement is reduced, so that the assembly and disassembly are correspondingly simplified. In the simplest case, only a single linear movement can be sufficient.

Gemäß einem Aspekt der Erfindung, die durch die technischen Merkmale bzw. die Verfahrensschritte des unabhängigen Vorrichtungsanspruchs 1 bzw. des unabhängigen Verfahrensanspruchs 13 definiert ist, betrifft diese daher eine Fahrwerkseinheit für ein Fahrzeug, insbesondere ein Schienenfahrzeug, mit einer Motorhalteeinrichtung, insbesondere einem Fahrwerksrahmen, und einer mit der Motorhalteeinrichtung verbindbaren Befestigungseinrichtung für eine Fahrmotoreinheit, wobei die Motorhalteeinrichtung eine Längsrichtung, eine Querrichtung, eine Höhenrichtung sowie in der Höhenrichtung eine Oberseite und eine Unterseite definiert. Die Motorhalteeinrichtung ist zur Abstützung auf wenigstens einer durch die Fahrmotoreinheit anzutreibenden Radeinheit in der Höhenrichtung ausgebildet. Die Befestigungseinrichtung ist zur im Wesentlichen starren Abstützung der Fahrmotoreinheit an der Motorhalteeinrichtung in der Höhenrichtung über wenigstens einen Formschluss ausgebildet, wobei die Befestigungseinrichtung derart ausgebildet ist, dass die Fahrmotoreinheit zur Montage der Fahrmotoreinheit an der Motorhalteeinrichtung auf einem Montagepfad, insbesondere von der Unterseite der Motorhalteeinrichtung her, in die Motorhalteeinrichtung einsetzbar ist. Die Befestigungseinrichtung weist wenigstens ein mit der Motorhalteeinrichtung und der Fahrmotoreinheit in Eingriff bringbares Befestigungselement auf, wobei das Befestigungselement bei im Bereich der Stützposition befindlicher Fahrmotoreinheit in einer quer zur Montagerichtung verlaufenden Verriegelungsrichtung in eine Verriegelungsposition bewegbar ist. Zudem wirkt das Befestigungselement in der Verriegelungsposition zur Abstützung der Fahrmotoreinheit in der Höhenrichtung über einen in der Höhenrichtung wirkenden ersten Formschluss mit der Motorhalteeinrichtung zusammen und über einen in der Höhenrichtung wirkenden zweiten Formschluss mit der Fahrmotoreinheit zusammen.According to one aspect of the invention, which is defined by the technical features and the method steps of the independent apparatus claim 1 and the independent method claim 13, this therefore relates to a chassis unit for a vehicle, in particular a rail vehicle, with a motor holding device, in particular a chassis frame, and a fastening device for a traction motor unit which can be connected to the motor holding device, wherein the motor holding device defines a longitudinal direction, a transverse direction, a height direction and in the height direction an upper side and a lower side. The motor holding device is designed to be supported on at least one wheel unit to be driven by the traction motor unit in the height direction. The fastening device is designed for substantially rigid support of the traction motor unit to the motor holding device in the height direction via at least one positive connection, wherein the fastening device is designed such that the traction motor unit for mounting the traction motor unit to the motor holding device on a mounting path, in particular from the bottom of the motor holding device forth , is used in the motor holding device. The fastening device has at least one fastening element that can be brought into engagement with the motor holding device and the traction motor unit, wherein the fastening element is movable into a locking position in a traction motor unit located in the region of the supporting position in a locking direction extending transversely to the mounting direction. In addition, the fastener acts in the locking position for supporting the traction motor unit in the height direction via a in the height direction acting first positive connection with the motor holding device together and via a force acting in the height direction second positive engagement with the drive motor unit together.

Es kann vorgesehen sein, dass das Befestigungselement die Fahrmotoreinheit über den ersten und zweiten Formschluss im Wesentlichen ausschließlich in der Höhenrichtung abstützt. Hierfür können an dem Befestigungselement und der Fahrmotoreinheit sowie der Motorhalteeinrichtung zur Ausbildung des ersten bzw. zweiten Formschlusses beispielsweise ebene, zur Höhenrichtung senkrechte Anschlagflächen vorgesehen sein. Die Abstützung der Fahrmotoreinheit in anderen Richtungen kann dann über beliebige geeignete andere Mittel (beispielsweise Schraubverbindungen etc.) gewährleistet sein.It may be provided that the fastening element supports the traction motor unit via the first and second positive locking essentially exclusively in the vertical direction. For this purpose, for example, flat, perpendicular to the vertical direction stop surfaces may be provided on the fastening element and the traction motor unit and the motor holding device for forming the first or second positive locking. The support of the traction motor unit in other directions can then be ensured by any other suitable means (such as screw etc.).

Bei bevorzugten Varianten der Erfindung mit reduzierter Anzahl an zusätzlichen Befestigungs- bzw. Sicherungselementen ist die Höhenrichtung eine erste Stützrichtung und das Befestigungselement in der Verriegelungsposition zur Abstützung der Fahrmotoreinheit in einer quer zur ersten Stützrichtung verlaufenden zweiten Stützrichtung ausgebildet, wobei die zweite Stützrichtung insbesondere quer zu der Verriegelungsrichtung verläuft. Hierbei kann vorgesehen sein, dass das Befestigungselement über einen in der zweiten Stützrichtung wirkenden dritten Formschluss mit der Motorhalteeinrichtung zusammenwirkt. Ebenso kann vorgesehen sein, dass das Befestigungselement über einen in der zweiten Stützrichtung wirkenden vierten Formschluss mit der Fahrmotoreinheit zusammenwirkt.In preferred variants of the invention with a reduced number of additional fastening or securing elements, the height direction is a first supporting direction and the fastening element is formed in the locking position for supporting the traction motor unit in a second supporting direction extending transversely to the first supporting direction, the second supporting direction in particular transversely to the Locking direction runs. In this case, it can be provided that the fastening element interacts with the motor holding device via a third positive connection acting in the second supporting direction. Likewise, it can be provided that the fastening element interacts with the traction motor unit via a fourth positive engagement acting in the second supporting direction.

Der erste Formschluss und der zweite Formschluss werden gemäss Anspruch 1 realisiert. Hiermit ist in vorteilhafter Weise sichergestellt, dass der jeweilige Formschluss in mehreren Richtungen wirkt.The first positive connection and the second positive connection are realized according to claim 1. This ensures in an advantageous manner that the respective form-fitting acts in several directions.

Hierbei ist also vorgesehen, dass eine Ausnehmung an der Motorhalteeinrichtung vorgesehen ist, während der zugeordnete Vorsprung an dem Befestigungselement angeordnet ist (oder umgekehrt). Ebenso ist eine Ausnehmung an der Fahrmotoreinheit vorgesehen, während der zugeordnete Vorsprung an dem Befestigungselement angeordnet ist (oder umgekehrt).In this case, it is thus provided that a recess is provided on the motor holding device, while the associated projection is arranged on the fastening element (or vice versa). Likewise, a recess is provided on the traction motor unit, while the associated projection is arranged on the fastening element (or vice versa).

Die Ausnehmung könnte in beliebiger Weise gestaltet sein, welche ein Montieren des Befestigungselements in der Verriegelungsposition erlaubt. So könnte die Ausnehmung beispielsweise als einfaches Durchgangsloch oder Sackloch des Befestigungselements gestaltet sein, wobei es einen beliebigen geeigneten Querschnitt (kreisförmig, abschnittsweise gekrümmt und/oder abschnittsweise polygonal etc.) aufweist. Erfindungsgemäss ist auf alle Fälle die Ausnehmung nach Art einer Nut ausgebildet, da hiermit eine besonders einfache Fertigung und spätere Montage des Befestigungselements möglich ist.The recess could be designed in any way that allows mounting of the fastener in the locked position. Thus, the recess could for example be designed as a simple through hole or blind hole of the fastener, wherein it has any suitable cross section (circular, partially curved and / or partially polygonal etc.). According to the invention, the recess is formed in the manner of a groove in all cases, since this is a particularly simple production and subsequent assembly of the fastener is possible.

Bei der Erfindung mit besonders einfacher Fertigung und späterer Montage des Befestigungselements weist das Befestigungselement zur Herstellung des ersten Formschlusses eine erste Ausnehmung und zur Herstellung des zweiten Formschlusses eine zweite Ausnehmung auf, wobei das Befestigungselement erfindungsgemäss im Wesentlichen S-förmig mit voneinander abgewandter erster Ausnehmung und zweiter Ausnehmung ausgebildet ist.In the invention with a particularly simple production and subsequent assembly of the fastener, the fastener for producing the first positive connection has a first recess and for producing the second positive connection, a second recess, wherein the fastener according to the invention substantially S-shaped with facing away from the first recess and second Recess is formed.

Der Kontaktbereich zwischen dem Befestigungselement und der Fahrmotoreinheit bzw. der Motorhalteeinrichtung kann so gestaltet sein, dass er über den Formschluss im Wesentlichen nur die Stützkraft in der Höhenrichtung aufbringt. Bevorzugt ist ein Kontaktbereich zwischen dem Befestigungselement und der Fahrmotoreinheit und/oder ein Kontaktbereich zwischen dem Befestigungselement und der Motorhalteeinrichtung derart gestaltet ist, dass er zur Aufnahme eines aus der Gewichtskraft der Fahrmotoreinheit resultierenden Moments ausgebildet ist. Hiermit wird in einfacher Weise eine verbesserte Abstützung bzw. eine Reduktion der hierfür erforderlichen Bauteile erzielt. Vorzugsweise ist bereits der den ersten Formschluss ausbildende Bereich und/oder der den zweite Formschluss ausbildende Bereich zur Aufnahme eines aus der Gewichtskraft der Fahrmotoreinheit resultierenden Moments ausgebildet, sodass diese Bereiche in vorteilhafter Weise sowohl die Funktion der Abstützung in der Höhenrichtung als auch die Abstützung eines derartigen Moments integrieren.The contact region between the fastening element and the traction motor unit or the motor holding device can be designed such that it essentially applies only the supporting force in the vertical direction via the positive locking. Preferably, a contact region between the fastening element and the traction motor unit and / or a contact region between the fastening element and the motor holding device is designed such that it is designed to receive a torque resulting from the weight force of the traction motor unit. Hereby, an improved support or a reduction of the components required for this purpose is achieved in a simple manner. Preferably, the area forming the first form-fitting connection and / or the area forming the second form-fitting are already formed for receiving a moment resulting from the weight force of the traction motor unit, so that these areas advantageously both the function of the support in the height direction and the support of such Integrate moments.

Der Montagepfad der Fahrmotoreinheit kann grundsätzlich einen beliebigen Verlauf aufweisen. Bevorzugt ist der Montagepfad natürlich möglichst geradlinig gestaltet, um die Komplexität der Bewegung der Fahrmotoreinheit bei der Montage bzw. Demontage ist gering zu halten. Vorzugsweise definiert der Montagepfad eine Montagerichtung, die in den beweglichkeitseingeschränkten Montageabschnitten, in denen Komponenten der Fahrmotoreinheit in einer die freie Beweglichkeit der Fahrmotoreinheit einschränkenden Weise an anderen Komponenten der Fahrwerkseinheit angrenzen, zumindest teilweise in der Höhenrichtung verläuft. Bevorzugt verläuft die Montagerichtung um weniger als 30°, vorzugsweise weniger als 15°, weiter vorzugsweise weniger als 5°, zu der Höhenrichtung geneigt, um eine möglichst einfache Hubbewegung bei der Montage/Demontage durchführen zu können.The assembly path of the drive motor unit can basically have any desired course. Of course, the mounting path is of course designed to be as straight as possible in order to minimize the complexity of the movement of the traction motor unit during assembly or disassembly. Preferably, the mounting path defines an assembly direction, which in the mobility limited mounting portions, in which components of the traction motor unit in a free mobility of the traction motor unit limiting manner to other components of the chassis unit, at least partially in the Height direction runs. Preferably, the mounting direction is less than 30 °, preferably less than 15 °, more preferably less than 5 °, inclined to the height direction in order to perform the simplest possible lifting movement during assembly / disassembly can.

Die Fahrmotoreinheit kann bei der Montage/Demontage grundsätzlich eine beliebig komplexe Bewegung entlang ihres Montagepfades ausführen, was den angrenzenden Einbauten geschuldet sein kann. Vorzugsweise ist jedoch ein möglichst geradliniger Montagepfad vorgesehen, um die Komplexität der Bewegung zu reduzieren und damit die Montage zu vereinfachen. Bei besonders günstigen Varianten der vorliegenden Erfindung ist daher vorgesehen, dass eine durch die Montagebewegung der der Fahrmotoreinheit definierte Einhüllende der Fahrmotoreinheit bei der Montage der Fahrmotoreinheit in den beweglichkeitseingeschränkten Montageabschnitten einen mindesterforderlichen Montagekanal mit einer Mittenlinie definiert, wobei die Mittenlinie einen Startpunkt bei Eintritt in die beweglichkeitseingeschränkten Montageabschnitte definiert sowie einen Endpunkt in der Stützposition definiert. Der in einer Abstandsrichtung gemessene Abstand der Mittenlinie von einer Verbindungsgeraden zwischen dem Startpunkt dem Endpunkt beträgt dann weniger als 15%, vorzugsweise weniger als 5%, weiter vorzugsweise weniger als 2%, der Abmessung der Fahrmotoreinheit in der Abstandsrichtung beträgt, um zumindest eine möglichst weit gehende Annäherung an einen geradlinigen Verlauf zu erzielen.The drive motor unit can basically perform any complex movement along its mounting path during assembly / disassembly, which may be due to the adjacent internals. Preferably, however, a possible rectilinear mounting path is provided in order to reduce the complexity of the movement and thus simplify the assembly. In particularly favorable variants of the present invention it is therefore provided that an envelope of the traction motor unit defined by the assembly movement of the traction motor unit defines a minimum required mounting channel with a center line during assembly of the traction motor unit in the limited mobility mounting sections, the center line having a starting point upon entry into the agility limited Assembly sections defined and defines an end point in the support position. The measured distance in a distance direction of the center line of a connecting line between the starting point the end point is then less than 15%, preferably less than 5%, more preferably less than 2%, the dimension of the traction motor unit in the distance direction is at least one as far as possible going approaching to achieve a straight-line course.

Das Befestigungselement kann selbst schon so gestaltet sein, dass es das aus der Gewichtskraft der Fahrmotoreinheit resultierende Drehmoment aufnehmen kann. Vorzugsweise ist jedoch vorgesehen, dass das Befestigungselement in der Stützposition der Fahrmotoreinheit in einem ersten Stützabschnitt angeordnet ist und die Fahrmotoreinheit die Motorhalteeinrichtung zur Aufnahme von aus der Gewichtskraft der Fahrmotoreinheit resultierenden Momenten in wenigstens einem von dem ersten Stützabschnitt beabstandeten zweiten Stützabschnitt direkt oder über wenigstens ein Stützelement kontaktiert. Hiermit wird eine besonders einfache Gestaltung des Befestigungselements möglich.The fastener itself may already be designed so that it can absorb the torque resulting from the weight of the drive motor unit. Preferably, however, it is provided that the fastening element is arranged in the support position of the drive motor unit in a first support portion and the drive motor unit, the motor holding device for receiving resulting from the weight of the drive motor unit moments in at least one of the first support portion spaced second support portion directly or via at least one support element contacted. This makes a particularly simple design of the fastener possible.

Das Befestigungselement kann grundsätzlich so gestaltet und/oder angeordnet sein, dass es im Betrieb der Fahrwerkseinheit durch die aus der Gewichtskraft der Fahrmotoreinheit resultierenden Kräfte in seiner Verriegelungsposition gehalten wird. Vorzugsweise ist jedoch eine Sicherungseinrichtung vorgesehen, welche das Befestigungselement in der Stützposition, insbesondere entlang der Verriegelungsrichtung, gegen eine Verschiebung aus seiner Position sichert. Diese Sicherungseinrichtung kann an beliebiger Stelle an der Fahrwerkseinheit befestigt sein. Vorzugsweise ist die Sicherungseinrichtung lösbar mit der Motorhalteeinrichtung verbunden. Die Sicherungseinrichtung an in beliebiger geeigneter Weise gestaltet sein. So können beispielsweise einfache Schrauben oder dergleichen hierfür vorgesehen sein. Weiterhin kann die Sicherungseinrichtung wenigstens ein Sicherungselement, insbesondere in Form einer Sicherungsplatte, umfassen, weiches die Sicherung des Befestigungselements in seiner Verriegelungsposition sicherstellt.The fastening element can in principle be designed and / or arranged such that it is held in its locking position during operation of the chassis unit by the forces resulting from the weight force of the traction motor unit. Preferably, however, a securing device is provided, which secures the fastening element in the supporting position, in particular along the locking direction, against displacement from its position. This safety device can be attached to any position on the chassis unit. Preferably, the securing device is releasably connected to the motor holding device. The safety device in any suitable Be fashioned. For example, simple screws or the like may be provided for this purpose. Furthermore, the securing device may comprise at least one securing element, in particular in the form of a securing plate, which ensures the securing of the fastening element in its locking position.

Bei bevorzugten Varianten der erfindungsgemäßen Fahrwerkseinheit ist die Verbindung zwischen dem Befestigungselement und der Motorhalteeinrichtung im Bereich des ersten Formschlusses selbstzentrierend ausgebildet. Hierzu kann sie in einer besonders einfach gestalteten Variante eine zumindest abschnittsweise keilförmige Ausnehmung umfassen. Gleiches gilt zusätzlich oder alternativ für die Verbindung zwischen dem Befestigungselement und der Fahrmotoreinheit im Bereich des zweiten Formschlusses.In preferred variants of the chassis unit according to the invention, the connection between the fastening element and the motor holding device in the region of the first positive connection is formed selbstzentrierend. For this purpose, it may comprise an at least partially wedge-shaped recess in a particularly simple variant. The same applies additionally or alternatively for the connection between the fastening element and the drive motor unit in the region of the second positive connection.

Die Bewegung des Befestigungselements in seiner Verriegelungsposition kann auf beliebige geeignete Weise erfolgen. In einer besonders einfach zu realisierenden Variante der Erfindung ist das Befestigungselement als separates, frei in die Verriegelungsposition bewegliches Element ausgebildet. Alternativ kann das Befestigungselement schwenkbar an der Fahrmotoreinheit und/oder der Motorhalteeinrichtung angelenkt sein, wodurch sich die Handhabung des Befestigungselements bei der Bewegung in die Verriegelungsposition vereinfacht. Vergleichbares gilt für Varianten, bei denen das Befestigungselement verschieblich an der Fahrmotoreinheit und/oder der Motorhalteeinrichtung gelagert ist.The movement of the fastener in its locking position can be done in any suitable manner. In a particularly easy-to-implement variant of the invention, the fastening element is designed as a separate, freely movable into the locking position element. Alternatively, the fastener may be pivotally coupled to the traction motor unit and / or the motor retainer, thereby facilitating handling of the fastener upon movement to the lock position. The same applies to variants in which the fastening element is displaceably mounted on the traction motor unit and / or the motor holding device.

Es versteht sich, dass gegebenenfalls ein einziges entsprechend tragfähig gestaltetes Befestigungselement ausreichen kann. Bei bevorzugten Varianten der erfindungsgemäßen Fahrwerkseinheit ist jedoch eine Mehrzahl von Befestigungselementen vorgesehen, wobei die Befestigungselemente in ihrer Verriegelungsposition, insbesondere in der Verriegelungsrichtung, beabstandet sind. Hierdurch verringert sich zum einen der Aufwand für das einzelne Befestigungselement. Zum anderen besteht hierbei angesichts der Bauraumrestriktionen im Fahrwerk größerer Spielraum für die Anordnung des einzelnen Befestigungselements.It is understood that, where appropriate, a single appropriately designed fastener can be sufficient. In preferred variants of the chassis unit according to the invention, however, a plurality of fastening elements is provided, wherein the fastening elements are spaced in their locking position, in particular in the locking direction. As a result, on the one hand reduces the effort for the individual fastener. On the other hand, there is greater scope for the arrangement of the individual fastener given the space restrictions in the chassis.

Die Erfindung lässt sich besonders vorteilhaft im Zusammenhang mit Drehgestellen einsetzen, die einen Drehgestellrahmen als Motorhalteeinrichtung aufweisen. Dabei kommen ihre Vorteile besonders zum Tragen, wenn das Drehgestell zwei Radeinheiten aufweist, die jeweils von einer zugeordneten, am Drehgestellrahmen befestigten Fahrmotoreinheit angetrieben sein können.The invention can be used particularly advantageously in connection with bogies having a bogie frame as a motor holding device. In this case, their advantages come into play especially when the bogie has two wheel units, which can each be driven by an associated, attached to the bogie frame drive motor unit.

Die vorliegende Erfindung betrifft weiterhin ein Fahrzeug, insbesondere ein Schienenfahrzeug, mit einem Wagenkasten und einer den Wagenkasten abstützenden erfindungsgemäßen Fahrwerkseinheit. Hiermit lassen sich die oben beschriebenen Varianten und Vorteile in demselben Maß realisieren, sodass hier lediglich auf die obigen Ausführungen verwiesen wird.The present invention further relates to a vehicle, in particular a rail vehicle, with a car body and the vehicle body supporting the vehicle body according to the invention. This makes it possible to realize the variants and advantages described above to the same extent, so that reference is made here only to the above statements.

Die vorliegende Erfindung betrifft weiterhin das o.g. Verfahren gemäss Anspruch 13 zur Montage einer Fahrmotoreinheit an einer Fahrwerkseinheit eines Fahrzeugs, insbesondere eines Schienenfahrzeugs, bei dem die Fahrmotoreinheit zur Montage an einer Motorhalteeinrichtung der Fahrwerkseinheit auf einem Montagepfad in die Motorhalteeinrichtung eingesetzt und bis in eine Stützposition gebracht wird und die Fahrmotoreinheit mittels einer Befestigungseinrichtung an der Motorhalteeinrichtung derart befestigt wird, dass die Fahrmotoreinheit im Wesentlichen starr an der Motorhalteeinrichtung in einer Höhenrichtung über wenigstens einen Formschluss abgestützt wird. Die Befestigungseinrichtung umfasst wenigstens ein Befestigungselement, das mit der Motorhalteeinrichtung und der Fahrmotoreinheit in der Stützposition in Eingriff gebracht wird. Die Motorhalteeinrichtung ist zur Abstützung auf wenigstens einer durch die Fahrmotoreinheit anzutreibenden Radeinheit in der Höhenrichtung ausgebildet ist und definiert eine Längsrichtung, eine Querrichtung sowie die Höhenrichtung. Das Befestigungselement wird bei im Bereich der Stützposition befindlicher Fahrmotoreinheit in einer quer zur Montagerichtung verlaufenden Verriegelungsrichtung in eine Verriegelungsposition gebracht, wobei das Befestigungselement in der Verriegelungsposition zur Abstützung der Fahrmotoreinheit in der Höhenrichtung über einen in der Höhenrichtung wirkenden ersten Formschluss mit der Motorhalteeinrichtung zusammenwirkt und über einen in der Höhenrichtung wirkenden zweiten Formschluss mit der Fahrmotoreinheit zusammenwirkt. Auch hiermit lassen sich die oben beschriebenen Varianten und Vorteile in demselben Maß realisieren, sodass hier lediglich auf die obigen Ausführungen verwiesen wird.The present invention further relates to the above-mentioned. A method according to claim 13 for mounting a traction motor unit on a chassis unit of a vehicle, in particular a rail vehicle, wherein the traction motor unit is used for mounting on a motor holding device of the chassis unit on a mounting path in the motor holding device and brought to a support position and the traction motor unit by means of a fastening device the motor holding device is fixed such that the traction motor unit is substantially rigidly supported on the motor holding device in a height direction via at least one positive connection.

Erstes Ausführungsbeispiel (Erfindung)First embodiment (invention)

Die Figuren 1 bis 4 zeigen schematische Ansichten von Teilen eines erfindungsgemäßen Fahrzeugs in Form eines Schienenfahrzeugs 101, welches einen Wagenkasten (nicht dargestellt) umfasst, der auf einer Fahrwerkseinheit in Form eines Drehgestells 102 abgestützt ist. Das Drehgestell 102 umfasst einen Drehgestellrahmen 103, an dem eine Fahrmotoreinheit 104 befestigt ist, sodass der Drehgestellrahmen 103 mithin also eine Motorhalteeinrichtung im Sinne der vorliegenden Erfindung bildet.The FIGS. 1 to 4 show schematic views of parts of a vehicle according to the invention in the form of a rail vehicle 101, which comprises a car body (not shown) which is supported on a chassis unit in the form of a bogie 102. The bogie 102 includes a bogie frame 103, to which a traction motor unit 104 is attached, so that the bogie frame 103 thus forms a motor holding device according to the present invention.

Zum einfacheren Verständnis der nachfolgenden Erläuterungen ist in den Figuren ein Fahrwerks-Koordinatensystem x,y,z angegeben (das im geraden ebenen Gleis mit dem Koordinatensystem des Fahrzeugs 102 zusammenfällt). In diesem Koordinatensystem bezeichnet die x-Koordinate die Längsrichtung des Drehgestellrahmens, die y-Koordinate die Querrichtung des Drehgestellrahmens 103 und die z-Koordinate die Höhenrichtung des Drehgestellrahmens 103.For ease of understanding of the following explanations, a chassis coordinate system x, y, z is indicated in the figures (coinciding in the even plane track with the coordinate system of the vehicle 102). In this coordinate system, the x coordinate denotes the longitudinal direction of the bogie frame, the y coordinate the lateral direction of the bogie frame 103, and the z coordinate the height direction of the bogie frame 103.

Der Drehgestellrahmen 103 ist in der Höhenrichtung (z-Richtung) auf zwei Radeinheiten (nicht dargestellt) in Form von Radsätzen abgestützt, die jeweils von einer Fahrmotoreinheit 104 angetrieben werden. Die Fahrmotoreinheit 104 ist in ihrer in den Figuren 1 und 2 zwei dargestellten Stützposition über eine Befestigungseinrichtung 105 im Wesentlichen starr an den Drehgestellrahmen 103 befestigt und in somit der Höhenrichtung (z-Richtung) abgestützt.The bogie frame 103 is supported in the height direction (z-direction) on two wheel units (not shown) in the form of wheelsets, which are each driven by a drive motor unit 104. The drive motor unit 104 is in its in the FIGS. 1 and 2 two support position shown via a fastening device 105 substantially rigidly attached to the bogie frame 103 and thus in the height direction (z-direction) supported.

Zu diesem Zweck umfasst die Befestigungseinrichtung 105 vier Befestigungselemente 106, die sich in den in den Figuren 1 und 2 dargestellten Zuständen in einer Verriegelungsposition befinden, in der sie einerseits jeweils mit einem ersten Befestigungsabschnitt 103.1 des Drehgestellrahmens 103 und andererseits mit einem zweiten Befestigungsabschnitt 104.1 der Fahrmotoreinheit 104 in formschlüssigem Eingriff befinden, wie dies nachfolgend anhand eines der Befestigungselement 106 beschrieben wird.For this purpose, the fastening device 105 comprises four fastening elements 106, which in the in the FIGS. 1 and 2 States in a locking position in which they are on the one hand in each case with a first attachment portion 103.1 of the bogie frame 103 and on the other hand with a second attachment portion 104.1 of the drive motor unit 104 in positive engagement, as will be described below with reference to one of the fastener 106.

So ist zum einen an dem ersten Befestigungsabschnitt 103.1 ein erster Vorsprung 103.2 ausgebildet, der in eine zumindest abschnittsweise komplementäre erste Ausnehmung in Form einer ersten Nut 105.1 in dem Befestigungselement 106 eingreift. Zum anderen ist an der Fahrmotoreinheit 104 ein zweiter Vorsprung 104.2 ausgebildet, der in eine zumindest abschnittsweise komplementäre zweite Ausnehmung in Form einer zweiten Nut 106.2 eingreift.For example, a first projection 103.2 is formed on the first fastening section 103.1, which engages in an at least partially complementary first recess in the form of a first groove 105.1 in the fastening element 106. On the other hand, a second projection 104.2 is formed on the traction motor unit 104, which engages in an at least partially complementary second recess in the form of a second groove 106.2.

Der erste Befestigungsabschnitt 103.1 ist im vorliegenden Beispiel durch ein entsprechendes Formteil realisiert, welches an den Drehgestellrahmen 103 befestigt ist, beispielsweise verschweißt ist. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung auch vorgesehen sein kann, dass der erste Befestigungsabschnitt monolithisch mit dem Drehgestellrahmen ausgebildet ist. Ebenso kann eine beliebige lösbare Verbindung mit dem Drehgestellrahmen vorgesehen sein.The first attachment portion 103.1 is realized in the present example by a corresponding molding, which is attached to the bogie frame 103, for example, is welded. However, it is understood that in other variants of the invention can also be provided that the first mounting portion is monolithically formed with the bogie frame. Likewise, any releasable connection may be provided with the bogie frame.

Der zweite Vorsprung 104.2 ist jeweils durch einen sich in der Querrichtung (y-Richtung) erstreckenden stiftartigen Vorsprung gebildet, der am freien Ende einer sich in der Längsrichtung (x-Richtung) erstreckenden Befestigungslasche 104.3 der Fahrmotoreinheit 104 angeordnet ist.The second projection 104.2 is formed by a pin-like projection extending in the transverse direction (y-direction), which is disposed at the free end of a fastening tab 104.3 of the traveling motor unit 104 extending in the longitudinal direction (x-direction).

Wie der Figur 1 zu entnehmen ist, sind im vorliegenden Beispiel in einem ersten Stützabschnitt 107.1 im Bereich der Oberseite der Fahrmotoreinheit 104 zwei in der Querrichtung beanstandete erste Befestigungslaschen 104.3 vorgesehen, an denen jeweils zwei solche in entgegengesetzte Richtung weisende stiftartige Vorsprünge 104.2 vorgesehen sind, um eine in Querrichtung möglichst gleichmäßige Abstützung der Fahrmotoreinheit 104 zu erzielen. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung auch eine andere Anzahl von ersten Befestigungslaschen und/oder stiftartigen Vorsprüngen vorgesehen sein kann. Insbesondere kann eine einzige Geste Befestigungslasche mit einem einzigen stiftartigen Vorsprung ausreichen.Again FIG. 1 can be seen, in the present example in a first support portion 107.1 in the region of the top of the drive motor unit 104 two spaced transgressed in the transverse direction of the first mounting tabs 104.3 provided, in each case two such pointing in the opposite direction pin-like projections 104.2 are to achieve as uniform as possible transverse support of the traction motor unit 104 in the transverse direction. It is understood, however, that in other variants of the invention, a different number of first fastening tabs and / or pin-like projections may be provided. In particular, a single gesture attachment tab may be sufficient with a single pin-like projection.

Durch die zur Höhenrichtung geneigt verlaufenden Begrenzungsflächen des ersten Vorsprungs 103.2 und der zugeordneten ersten Nut 106.1 ist ein in der Höhenrichtung wirkender erster Formschluss zwischen dem Drehgestellrahmen 103 und dem Befestigungselement 106 realisiert, während über die zur Höhenrichtung geneigt verlaufenden Begrenzungsflächen des zweiten Vorsprungs 104.2 und der zugeordneten zweiten Nut 106.2 ein ebenfalls in der Höhenrichtung wirkender zweiter Formschluss zwischen dem Befestigungselement 106 und der Fahrmotoreinheit 104 realisiert ist, sodass die Fahrmotoreinheit 104 über das Befestigungselement 106 in der Höhenrichtung (als einer ersten Stützrichtung) auf dem Drehgestellrahmen 103 verliersicher abgestützt ist.By the height direction inclined to the boundary surfaces of the first projection 103.2 and the associated first groove 106.1 acting in the height direction first positive connection between the bogie frame 103 and the fastener 106 is realized, while about inclined to the height direction extending boundary surfaces of the second projection 104.2 and the associated second groove 106.2 is also realized in the height direction acting second positive connection between the fastener 106 and the traction motor unit 104 so that the traction motor unit 104 is supported captively on the bogie frame 103 via the fastener 106 in the height direction (as a first support direction).

Dank der jeweiligen Paarung aus Vorsprung und komplementärer Ausnehmung ist durch die zur Längsrichtung geneigt verlaufenden Begrenzungsflächen des ersten Vorsprungs 103.2 und der ersten Nut 106.1 weiterhin ein in der Längsrichtung (x-Richtung) wirkender dritter Formschluss zwischen dem Drehgestellrahmen 103 und dem Befestigungselement 106 realisiert. Mithin ist hierdurch also ein Formschluss in einer zweiten Stützrichtung (x-Richtung) realisiert, die quer zu der ersten Stützrichtung (z-Richtung) verläuft. Ebenso ist über die zur Längsrichtung geneigt verlaufenden Begrenzungsflächen des zweiten Vorsprungs 104.2 und der zweiten Nut 106.2 ein ebenfalls in der Längsrichtung wirkender vierter Formschluss zwischen dem Befestigungselement 106 und der Fahrmotoreinheit 104 realisiert. Demgemäß ist die Fahrmotoreinheit 104 über das Befestigungselement 106 ebenfalls formschlüssig in der Längsrichtung verliersicher an dem Drehgestellrahmen 103 abgestützt.Thanks to the respective pairing of projection and complementary recess, a third form-fit connection between the bogie frame 103 and the fastening element 106, which acts in the longitudinal direction (x-direction), is furthermore realized by the boundary surfaces of the first projection 103.2 and the first groove 106.1 inclined in the longitudinal direction. Consequently, this means that a form fit in a second support direction (x-direction) is realized, which extends transversely to the first support direction (z-direction). Likewise, a fourth interlocking connection, likewise acting in the longitudinal direction, between the fastening element 106 and the traction motor unit 104 is realized via the boundary surfaces of the second projection 104.2 and the second groove 106.2 inclined in the longitudinal direction. Accordingly, the traction motor unit 104 via the fastening element 106 is also positively secured in the longitudinal direction captive on the bogie frame 103.

Durch die komplementäre Gestaltung der Vorsprünge 103.2 bzw. 104.2 und der Nuten 106.1 bzw. 106.2 ist das Befestigungselement 106 grundsätzlich geeignet, aus der Gewichtskraft der Fahrmotoreinheit 104 resultierende Momente in den Drehgestellrahmen 103 einzuleiten. Um jedoch die Einleitung von Biegemomenten in das Befestigungselement 106 zu reduzieren und den Ausgleich von Fertigungstoleranzen zuzulassen, sind die Vorsprünge 104.2 um eine in Querrichtung verlaufende Achse drehbar an der Befestigungslasche 104.3 angeordnet.Due to the complementary design of the projections 103.2 or 104.2 and the grooves 106.1 or 106.2, the fastening element 106 is fundamentally suitable for introducing moments resulting from the weight force of the traction motor unit 104 into the bogie frame 103. However, in order to reduce the introduction of bending moments into the fastener 106 and allow for the compensation of manufacturing tolerances, the projections 104.2 are rotatably mounted about a transversely extending axis on the mounting tab 104.3.

Die erste Nut 106.1 und die zweiten Nut 106.2 sind einander abgewandt, sodass das Befestigungselement 106 eine im Wesentlichen S-förmige Gestalt aufweist. Weiterhin sind die erste Nut 106.1 und die zweite Nut 106.2 abschnittsweise keilförmig gestaltet, sodass es im Zusammenwirken mit den komplementären Abschnitten der Vorsprünge 103.2 bzw. 104.2 in vorteilhafter Weise zu einer Selbstzentrierung des jeweiligen Formschlusses kommt. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung eine Ausrichtung des Befestigungselements bezüglich des Drehgestellrahmens und/oder der Fahrmotoreinheit auf andere Weise bzw. durch separate Justagemittel oder dergleichen erfolgen kann.The first groove 106.1 and the second groove 106.2 are facing away from each other, so that the fastening element 106 has a substantially S-shaped configuration. Furthermore, the first groove 106.1 and the second groove 106.2 are wedge-shaped in sections so that, in cooperation with the complementary sections of the projections 103.2 or 104.2, advantageously, self-centering of the respective positive connection occurs. It is understood, however, that in other variants of the invention, an alignment of the fastener with respect to the bogie frame and / or the traction motor unit can be done in other ways or by separate adjustment means or the like.

Die zweite Nut 106.2 ist weiterhin so gestaltet, dass ihre den Nutgrund abgewandte Öffnung derart verengt ist, dass der zweite Vorsprung 104.2 nicht nach oben aus der zweiten Nut 106.2 herausgeführt werden kann. Hierüber ist somit in einfacher Weise eine weitere Verliersicherung realisiert.The second groove 106.2 is further designed such that its opening facing away from the groove bottom is narrowed such that the second projection 104.2 can not be led out of the second groove 106.2 upwards. This is thus realized in a simple way, a further captive.

Zur Abstützung von aus der Gewichtskraft der Fahrmotoreinheit 104 resultierenden Momenten ist in einem im Bereich der Unterseite der Fahrmotoreinheit 104 angeordneten zweiten Stützabschnitt 107.2 weiterhin eine zweite Befestigungslasche 104.4 angeordnet, an deren freien Ende ein Stützelement 104.5 befestigt ist, welches einen dritten Stützabschnitt 103.3 des Drehgestellrahmens 103 kontaktiert. Die Befestigungslasche 104.4 ist in Querrichtung (y-Richtung) etwa mittig zwischen den beiden Befestigungslaschen 104.3 angeordnet.In order to support moments resulting from the weight force of the traction motor unit 104, a second fastening tab 104.4 is further arranged in a second support section 107.2 arranged in the region of the underside of the traction motor unit 104, at the free end of which a supporting element 104.5 is secured, which has a third support section 103.3 of the bogie frame 103 contacted. The fastening tab 104.4 is arranged approximately centrally between the two fastening straps 104.3 in the transverse direction (y-direction).

Die Kontaktflächen zwischen dem Stützelement 104.5 und dem dritten Stützabschnitt 103.3 sind so gestaltet, dass ein Formschluss in der Längsrichtung (x-Richtung) realisiert ist. Im vorliegenden Beispiel verlaufen die Kontaktflächen hierzu senkrecht zur Längsrichtung.The contact surfaces between the support member 104.5 and the third support portion 103.3 are designed so that a positive connection in the longitudinal direction (x-direction) is realized. In the present example, the contact surfaces extend perpendicular to the longitudinal direction.

Das Stützelement 104.5 ist zum Ausgleich von Fertigungstoleranzen wiederum um eine in der Querrichtung (y-Richtung) verlaufende Achse drehbar an der zweiten Befestigungslasche 104.4 gelagert. Dies hat auch zufolge, dass über das Stützelement 104.5 primär eine Stützkraft in Richtung der Längsachse in die Fahrmotoreinheit 104 eingeleitet wird.In order to compensate for manufacturing tolerances, the support element 104.5 is in turn rotatably mounted on the second fastening lug 104.4 about an axis running in the transverse direction (y-direction). This also has, according to that, a support force in the direction of the longitudinal axis in the drive motor unit 104 is primarily initiated via the support element 104.5.

Wie insbesondere der Figur 3 zu entnehmen ist, wird die Fahrmotoreinheit 104 im vorliegenden Beispiel von einer (in Figur 3 durch die gestrichelte Kontur 110 angedeuteten) Startposition von der Unterseite 103.4 des Drehgestellrahmens 103 her in den Drehgestellrahmen 103 eingesetzt. Hierbei wird die Fahrmotoreinheit 104 in einer Montagebewegung auf einem Montagepfad 108 bis zu ihrer (in Figur 3 durch die gepunktete Kontur 111 angedeutete)n Stützposition geführt.How the particular FIG. 3 can be seen, the traction motor unit 104 in the present example of a (in FIG. 3 indicated by the dashed contour 110) starting position of the bottom 103.4 of the bogie frame 103 ago inserted into the bogie frame 103. Here, the traction motor unit 104 is in a mounting movement on a mounting path 108 to its (in FIG. 3 guided by the dotted contour 111 indicated) n supporting position.

Bei dieser Montagebewegung definiert die Fahrmotoreinheit 104 eine Einhüllende 109, die wiederum eine Mittellinie 109.1 definiert, die entlang der Montagerichtung verläuft. Diese Einhüllende 109 stellt einen mindesterforderlichen Montagekanal dar, der für die Montage der Fahrmotoreinheit 104, mithin also die Bewegung der Fahrmotoreinheit 104 in ihre Stützposition, freizuhalten ist.In this assembly movement, the traction motor unit 104 defines an envelope 109, which in turn defines a centerline 109.1 that extends along the mounting direction. This envelope 109 represents a minimum required mounting channel, which is to be kept free for the assembly of the traction motor unit 104, thus the movement of the traction motor unit 104 in its supporting position.

Wie der Figur 3 weiterhin zu entnehmen ist, sind die Befestigungselemente 106 beim Einsetzen der Fahrmotoreinheit 104 in den Drehgestellrahmen 103 zunächst sowohl von dem Drehgestellrahmen 103 als auch der Fahrmotoreinheit 104 entfernt. Erst wenn die Fahrmotoreinheit 104 eine gegenüber der Stützposition um einen Abstand H leicht erhöhte Zwischenposition erreicht hat, wie sie in Figur 4 angedeutet ist, werden die Befestigungselemente 106 in einer in der Querrichtung (y-Richtung) verlaufenden Verriegelungsrichtung (von beiden Seiten der jeweiligen Befestigungslasche 104.3 her) zwischen den Drehgestellrahmen 103 und die Fahrmotoreinheit 104 eingesetzt. Ist dies geschehen, wird die Fahrmotoreinheit 104 in ihre Stützposition abgesenkt, in der sie über die Befestigungselemente 106 und das Stützelement 104.5 an dem Drehgestellrahmen 103 abgestützt wird.Again FIG. 3 1, the fasteners 106 are initially removed from the bogie frame 103 as well as the traction motor unit 104 upon insertion of the traction motor unit 104 into the bogie frame 103. Only when the traction motor unit 104 has reached a relative to the support position by a distance H slightly increased intermediate position, as in FIG. 4 is indicated, the fastening elements 106 in a transverse direction (y direction) extending locking direction (from both sides of the respective fastening tab 104.3 forth) between the bogie frame 103 and the drive motor unit 104 is inserted. Once this is done, the traction motor unit 104 is lowered to its supporting position in which it is supported on the bogie frame 103 via the fastening elements 106 and the supporting element 104.5.

Dank der bei der Montagebewegung zunächst in der beschriebenen Weise entfernten bzw. nicht vorhandenen Befestigungselemente 106 kann der zweite Vorsprung 104.2 an der Fahrmotoreinheit 104 (in der Längsrichtung) in einem sehr geringen Abstand D an dem Drehgestellrahmen 103, insbesondere an den ersten Vorsprung 103.2, vorbeigeführt werden, ohne dass hierfür eine Ausweichbewegung quer zur Montagerichtung, insbesondere in der Längsrichtung (x-Richtung) und/oder der Querrichtung (y-Richtung), erforderlich ist.Thanks to the first during the assembly movement in the manner described removed or not present fasteners 106, the second projection 104.2 on the drive motor unit 104 (in the longitudinal direction) at a very small distance D to the bogie frame 103, in particular to the first projection 103.2, passed be without this an evasive movement transverse to the mounting direction, in particular in the longitudinal direction (x-direction) and / or the transverse direction (y-direction) is required.

Hiermit ist es im vorliegenden Beispiel insbesondere möglich, den Montagekanal 109 bzw. seine Mittellinie 109.1 in den beweglichkeitseingeschränkten Montageabschnitten, in denen die Fahrmotoreinheit 104 durch angrenzende Bauteile des Drehgestells 102 (insbesondere des Drehgestellrahmens 103) in ihrer freien Beweglichkeit eingeschränkt ist, geradlinig zu gestalten.This makes it possible in the present example, in particular, the mounting channel 109 and its center line 109.1 in the limited mobility mounting sections in which the drive motor unit 104 is limited by adjacent components of the bogie 102 (in particular of the bogie frame 103) in their free mobility to make straight.

Hierdurch wird zum einen erreicht, dass der Montagekanal 109 möglichst wenig Bauraum beansprucht. Zum anderen wird hierdurch eine besonders einfach zu bewerkstelligende Montagebewegung der Fahrmotoreinheit 104 erzielt, nämlich im vorliegenden Beispiel eine einfache geradlinige Hubbewegung in der Höhenrichtung.As a result, on the one hand ensures that the mounting channel 109 takes up as little space. On the other hand, a particularly easy to be accomplished installation movement of the drive motor unit 104 is achieved, namely in the present example, a simple straight-line lifting movement in the height direction.

Die Mittellinie 109.1 verläuft im gezeigten Beispiel (siehe Figur 3) in den beweglichkeitseingeschränkten Montageabschnitten zwischen einem Startpunkt 109.2 und einem Endpunkt 109.3 geradlinig.The center line 109.1 runs in the example shown (see FIG. 3 ) in the mobility limited mounting portions between a starting point 109.2 and an end point 109.3 rectilinear.

Der Startpunkt 109.2 und der Endpunkt 109.3 sind im vorliegenden Beispiel durch den Schnittpunkt der Mittellinie 109.1 mit der zur Höhenrichtung senkrechten Ebene in der Startposition (siehe Kontur 110 in Figur 3, die den Eintritt in die beweglichkeitseingeschränkten Montageabschnitte markiert) bzw. der Stützposition (siehe Kontur 111 in Figur 3) definiert, in welcher die Längsachse der Antriebswelle der Fahrmotoreinheit 104 liegt. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung auch jeder beliebige andere Bezugspunkt der Fahrmotoreinheit 104 gewählt werden kann, um den Startpunkt und den Endpunkt auf der Mittellinie des Montagekanals zu definieren.The starting point 109.2 and the end point 109.3 in the present example are the intersection of the center line 109.1 with the plane perpendicular to the height direction in the start position (see contour 110 in FIG FIG. 3 indicating the entry into the restricted mobility mounting portions) or the support position (see contour 111 in FIG FIG. 3 ), in which the longitudinal axis of the drive shaft of the traction motor unit 104 is located. It is understood, however, that in other variants of the invention, any other reference point of the traction motor unit 104 may be selected to define the starting point and the end point on the center line of the mounting channel.

Wie Figur 3 durch die strichzweipunktierte Kontur 112 angedeutet ist, kann bei anderen Varianten der Erfindung auch ein beliebiger anderweitiger (abschnittsweise geradliniger und/oder abschnittsweise gekrümmter) Verlauf des Montagekanals 109 und damit der Mittellinie 109.1 zwischen den Startpunkt 109.2 und den Endpunkt 109.3 vorgesehen sein. Vorzugsweise liegt der maximale Abstand A zwischen der Mittellinie 112 und der Verbindungsgeraden des Startpunkts 109.2 und den Endpunkts 109.3 bei weniger als 15% der maximalen Abmessung M der Fahrmotoreinheit 104 (in der Richtung des Abstands A). Hierdurch ist ein möglichst nahe an den geradlinigen Verlauf angenäherter Montagekanal mit geringem Platzbedarf und einfache zu realisierender Montagebewegung erzielt.As FIG. 3 is indicated by the dash-dotted contour 112, in other variants of the invention, any other (sectionally rectilinear and / or partially curved) course of the mounting channel 109 and thus the center line 109.1 be provided between the starting point 109.2 and the end point 109.3. Preferably, the maximum distance A between the center line 112 and the connecting straight line of the starting point 109.2 and the end point 109.3 is less than 15% of the maximum dimension M of the traveling motor unit 104 (in the direction of the distance A). As a result, as close as possible to the rectilinear course of the assembly channel is achieved with a small footprint and easy to be realized assembly movement.

Im vorliegenden Beispiel verläuft der Montagekanal 109, dessen Mittellinie 109.1 und damit auch die Montagerichtung parallel zu der Höhenrichtung. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung vorgesehen sein kann, dass die Mittellinie des Montagekanals bzw. die Montagerichtung zu der Höhenrichtung geneigt verlaufen kann. Vorzugsweise beträgt die Neigung weniger als 30°, um eine möglichst einfach zu realisierende Montagebewegung zu erzielen.In the present example, the mounting channel 109, whose center line 109.1 and thus also the mounting direction runs parallel to the height direction. It is understood, however, that in other variants of the invention it can be provided that the center line of the mounting channel or the mounting direction can be inclined to the height direction. Preferably, the inclination is less than 30 ° in order to achieve as simple as possible to realize assembly movement.

Sobald sich die Befestigungselemente 106 in ihrer in den Figuren 1 und 2 dargestellten Verriegelungsposition befinden und sich die Fahrmotoreinheit 104 in ihrer Stützposition befindet, werden die Befestigungselemente 106 über Sicherungselemente 113.1, 113.2 einer Sicherungseinrichtung 113 in ihrer Lage bezüglich des Drehgestellrahmens 103 und der Fahrmotoreinheit 104 gesichert. Insbesondere wird hierdurch verhindert, dass sich die Befestigungselemente im Betrieb des Fahrzeugs 101 (beispielsweise infolge von Vibrationen) aus ihrer Verriegelungsposition lösen.Once the fasteners 106 in their in the FIGS. 1 and 2 are located and the traction motor unit 104 is in its supporting position, the fastening elements 106 are secured via securing elements 113.1, 113.2 a securing device 113 in its position relative to the bogie frame 103 and the traction motor unit 104. In particular, this prevents the fasteners from disengaging from their locking position during operation of the vehicle 101 (due to, for example, vibrations).

Im vorliegenden Beispiel werden hierzu zum einen Sicherungsplatten 113.1 mit dem Drehgestellrahmen 103 verschraubt, um eine Bewegung des Befestigungselements 106 in der Querrichtung zu verhindern. Weiterhin werden die Befestigungselemente 106 über Sicherungsschrauben 113.2 mit den Vorsprüngen 104.2 verschraubt. Es versteht sich jedoch, dass auch beliebige andere Sicherungselemente zum Einsatz kommen können. Schließlich wird das Stützelement 104.5 noch mit dem zweiten Stützabschnitt 103.3 des Drehgestellrahmens 103 verschraubt, um in diesem Bereich eine Abhebesicherung zu realisieren. Auch hier versteht es sich, dass ein beliebiger anderer geeigneter Sicherungsmechanismus zum Einsatz kommen kann.For this purpose, in the present example, securing plates 113.1 are bolted to the bogie frame 103 in order to prevent movement of the fastening element 106 in the transverse direction. Furthermore, the fastening elements 106 are screwed via locking screws 113.2 with the projections 104.2. It is understood, however, that any other security elements can be used. Finally, the support element 104.5 is still bolted to the second support section 103.3 of the bogie frame 103 in order to realize a lift-off protection in this area. Again, it is understood that any other suitable securing mechanism may be used.

Zweites AusführungsbeispielSecond embodiment

Eines weitere, zur Erfindung nicht gehörenden Ausführungsform einer Fahrwerkseinheit 202, die in dem Fahrzeug 101 anstelle der Fahrwerkseinheit 102 zum Einsatz kommen kann ist in Figur 5 dargestellt. Die Fahrwerkseinheit 202 entspricht dabei in ihrer grundsätzlichen Gestaltung und Funktionsweise der Fahrwerkseinheit 102 aus den Figuren 1 bis 4, sodass hier lediglich auf die Unterscheide eingegangen werden soll. Insbesondere sind gleichartige Bauteile mit um den Wert 100 erhöhten Bezugziffern versehen. Insoweit nachfolgend keine abweichenden Angaben gemacht werden, wird bezüglich der Merkmale dieser Bauteile ausdrücklich auf die obigen Ausführungen verwiesen.Another, not belonging to the invention embodiment of a chassis unit 202, which can be used in the vehicle 101 instead of the chassis unit 102 is in FIG. 5 shown. The chassis unit 202 corresponds in its basic design and operation of the chassis unit 102 from the FIGS. 1 to 4 , so that only the differences should be discussed here. In particular, similar components are provided with reference numbers increased by the value 100. Unless otherwise stated below, reference is made expressly to the above statements with regard to the features of these components.

Der einzige Unterschied zur Ausführung aus Figur 1 bis 4 besteht in der Gestaltung der Befestigungselemente 206, insbesondere der ersten Ausnehmung 206.1 und der zweiten Ausnehmungen 206.2, die beide nicht als Nut sondern als einfache Durchgangsöffnung in dem Befestigungselement 206 ausgebildet sind. Dementsprechend ist auch der erste Vorsprung 203.2 abweichend gestaltet, nämlich (ähnlich dem zweiten Vorsprung 104.2) als in Querrichtung ausgerichteter stiftartiger Vorsprung an einer Befestigungslasche 203.1 des Drehgestellrahmens 203.The only difference from the execution Figure 1 to 4 consists in the design of the fastening elements 206, in particular the first recess 206.1 and the second recesses 206.2, both of which are not formed as a groove but as a simple passage opening in the fastening element 206. Accordingly, the first projection 203.2 is designed differently, namely (similar to the second projection 104.2) as a transversely aligned pin-like projection on a mounting tab 203.1 of the bogie frame 203rd

Drittes AusführungsbeispielThird embodiment

Eine weitere, zur Erfindung nicht gehörenden Ausführung einer Fahrwerkseinheit 302, die in dem Fahrzeug 101 anstelle der Fahrwerkseinheit 102 zum Einsatz kommen kann ist in Figur 6 dargestellt. Die Fahrwerkseinheit 302 entspricht dabei in ihrer grundsätzlichen Gestaltung und Funktionsweise der Fahrwerkseinheit 102 aus den Figuren 1 bis 4, sodass hier lediglich auf die Unterscheide eingegangen werden soll. Insbesondere sind gleichartige Bauteile mit um den Wert 200 erhöhten Bezugziffern versehen. Insoweit nachfolgend keine abweichenden Angaben gemacht werden, wird bezüglich der Merkmale dieser Bauteile ausdrücklich auf die obigen Ausführungen verwiesen.Another, not belonging to the invention embodiment of a chassis unit 302, which can be used in the vehicle 101 instead of the chassis unit 102 is in FIG. 6 shown. The chassis unit 302 corresponds in its basic design and operation of the chassis unit 102 from the FIGS. 1 to 4 , so that only the differences should be discussed here. In particular, similar components are provided with reference numerals increased by the value 200. Unless otherwise stated below, reference is made expressly to the above statements with regard to the features of these components.

Der einzige Unterschied zur Ausführung aus Figur 1 bis 4 besteht in der Gestaltung der Befestigungselemente 306, die in diesem Beispiel nicht als separate Elemente sondern als um eine (in Höhenrichtung verlaufende) Schwenkachse 306.3 schwenkbar an dem Drehgestellrahmen 303 angelenkt sind. Für die Montage der Fahrmotoreinheit 104 werden die Befestigungselemente 306 zunächst um die Schwenkachse 306.3 aus dem Montagekanal heraus geschwenkt und erst in die gezeigte Position verschwenkt und mit der Fahrmotoreinheit 104 in Eingriff gebracht, wenn sich diese in der dargestellten Zwischenposition im Bereich der Stützposition befindet. Danach wird die Fahrmotoreinheit 104 in ihre Stützposition abgesenkt.The only difference from the execution Figure 1 to 4 consists in the design of the fasteners 306, which are hinged in this example not as separate elements but as to a (extending in the vertical direction) pivot axis 306.3 pivotally mounted on the bogie frame 303. For the assembly of the drive motor unit 104, the fastening elements 306 are first pivoted about the pivot axis 306.3 out of the mounting channel and pivoted only in the position shown and engaged with the drive motor unit 104 when it is in the illustrated intermediate position in the support position. Thereafter, the traction motor unit 104 is lowered to its supporting position.

Viertes AusführungsbeispielFourth embodiment

Eine weitere, zur Erfindung nicht gehörenden Ausführung einer Fahrwerkseinheit 402, die in dem Fahrzeug 101 anstelle der Fahrwerkseinheit 102 zum Einsatz kommen kann ist in Figur 7 dargestellt. Die Fahrwerkseinheit 402 entspricht dabei in ihrer grundsätzlichen Gestaltung und Funktionsweise der Fahrwerkseinheit 102 aus den Figuren 1 bis 4, sodass hier lediglich auf die Unterscheide eingegangen werden soll. Insbesondere sind gleichartige Bauteile mit um den Wert 300 erhöhten Bezugziffern versehen. Insoweit nachfolgend keine abweichenden Angaben gemacht werden, wird bezüglich der Merkmale dieser Bauteile ausdrücklich auf die obigen Ausführungen verwiesen.A further, not belonging to the invention embodiment of a chassis unit 402, which can be used in the vehicle 101 instead of the chassis unit 102 is in FIG. 7 shown. The chassis unit 402 corresponds in its basic design and operation of the chassis unit 102 from the FIGS. 1 to 4 , so that only the differences should be discussed here. In particular, similar components are provided with reference numbers increased by the value of 300. Unless otherwise stated below, reference is made expressly to the above statements with regard to the features of these components.

Der einzige Unterschied zur Ausführung aus Figur 1 bis 4 besteht in der Gestaltung der Befestigungselemente 406, die in diesem Beispiel als in der Längsrichtung (x-Richtung) verschieblich in dem Drehgestellrahmen 403 gelagerte Elemente gestaltet sind. Für die Montage der Fahrmotoreinheit 104 werden die Befestigungselemente 406 zunächst in der Längsrichtung aus dem Montagekanal heraus gezogen (wie dies in Figur 7 durch die gestrichelte Kontur 414 angedeutet ist) und erst in die gezeigte Position verschoben und mit der Fahrmotoreinheit 104 in Eingriff gebracht, wenn sich diese in der dargestellten Zwischenposition im Bereich der Stützposition befindet. Danach wird die Fahrmotoreinheit 104 in ihre Stützposition abgesenkt, in der dann der zweite Vorsprung 104.2 in der bekannten Weise in die zweite Nut 406.2 des Befestigungselements 406 formschlüssig eingreift.The only difference from the execution Figure 1 to 4 consists in the design of the fasteners 406, which are designed in this example as in the longitudinal direction (x-direction) slidably mounted in the bogie frame 403 elements. For mounting the drive motor unit 104, the fastening elements 406 are first pulled out of the mounting channel in the longitudinal direction (as shown in FIG FIG. 7 through the dashed contour 414 is indicated) and first moved into the position shown and brought into engagement with the drive motor unit 104 when it is in the illustrated intermediate position in the region of the support position. Thereafter, the traction motor unit 104 is lowered into its supporting position, in which then the second projection 104.2 engages in the known manner in the second groove 406.2 of the fastening element 406 form-fitting manner.

Das Befestigungselement 406 kann in dieser Position durch geeignete Mittel verriegelt werden. Ebenso können natürlich wiederum das Befestigungselement 406 und die Fahrmotoreinheit 104 über eine geeignete Abhebesicherung miteinander verbunden werden.The fastener 406 can be locked in this position by suitable means. Likewise, in turn, of course, the fastener 406 and the drive motor unit 104 can be connected to each other via a suitable lift-off.

Fünftes AusführungsbeispielFifth embodiment

Eine weitere, nicht zur Erfindung gehörenden Fahrwerkseinheit 502, die in dem Fahrzeug 101 anstelle der Fahrwerkseinheit 102 zum Einsatz kommen kann ist schließlich in Figur 8 dargestellt. Die Fahrwerkseinheit 502 entspricht dabei in ihrer grundsätzlichen Gestaltung und Funktionsweise der Fahrwerkseinheit 102 aus den Figuren 1 bis 4, sodass hier lediglich auf die Unterscheide eingegangen werden soll. Insbesondere sind gleichartige Bauteile mit um den Wert 300 erhöhten Bezugziffern versehen. Insoweit nachfolgend keine abweichenden Angaben gemacht werden, wird bezüglich der Merkmale dieser Bauteile ausdrücklich auf die obigen Ausführungen verwiesen.Another, not belonging to the invention chassis unit 502, which can be used in the vehicle 101 instead of the chassis unit 102 is finally in FIG. 8 shown. The chassis unit 502 corresponds in its basic design and operation of the chassis unit 102 from the FIGS. 1 to 4 , so that only the differences should be discussed here. In particular, similar components are provided with reference numbers increased by the value of 300. Unless otherwise stated below, reference is made expressly to the above statements with regard to the features of these components.

Der einzige Unterschied zur Ausführung aus Figur 1 bis 4 besteht auch hier in der Gestaltung der Befestigungselemente 506, die in diesem Beispiel wiederum als in der Längsrichtung (x-Richtung) verschieblich in dem Drehgestellrahmen 503 gelagerte Elemente gestaltet sind. Für die Montage der Fahrmotoreinheit 104 werden die Befestigungselemente 506 zunächst in der Längsrichtung aus dem Montagekanal heraus gezogen (wie dies in Figur 7 durch die gestrichelte Kontur 514 angedeutet ist) und erst in die gezeigte Position verschoben und mit der Fahrmotoreinheit 104 in Eingriff gebracht, wenn sich diese in der dargestellten Zwischenposition im Bereich der Stützposition befindet. Das Befestigungselement 506 kann in dieser Position durch geeignete Mittel verriegelt werden. Danach wird die Fahrmotoreinheit 104 in ihre Stützposition abgesenkt, in der dann der zweite Vorsprung 104.2 auf der zu Höhenrichtung senkrechten Oberfläche des Befestigungselements 506 aufliegt.The only difference from the execution Figure 1 to 4 Again, this is the design of the fasteners 506, which in turn are designed in this example as in the longitudinal direction (x-direction) slidably mounted in the bogie frame 503 elements. For the assembly of the traction motor unit 104, the fastening elements 506 are first pulled out of the mounting channel in the longitudinal direction (as shown in FIG FIG. 7 is indicated by the dashed contour 514) and first moved into the position shown and engaged with the drive motor unit 104 when it is in the illustrated intermediate position in the region of the support position. The fastener 506 can be locked in this position by suitable means. Thereafter, the traction motor unit 104 is lowered to its supporting position, in which then the second projection 104.2 rests on the surface perpendicular to the height direction of the fastening element 506.

Hierdurch wird lediglich ein Formschluss in der Höhenrichtung zwischen dem Befestigungselement 506 und dem zweiten Vorsprung 104.2 realisiert. Um eine Lagesicherung zwischen dem Befestigungselement 506 und dem zweiten Vorsprung 104.2 zu erzielen werden das Befestigungselement 506 und die Fahrmotoreinheit 104 über eine geeignete Sicherung miteinander verbunden, sodass quer zu der Höhenrichtung beispielsweise eine reibschlüssige Verbindung vorliegt.As a result, only a positive connection in the height direction between the fastening element 506 and the second projection 104.2 is realized. In order to achieve a position assurance between the fastening element 506 and the second projection 104.2, the fastening element 506 and the traction motor unit 104 are connected via a suitable fuse connected to each other, so that for example there is a frictional connection transverse to the height direction.

Die vorliegende Erfindung wurde vorstehend ausschließlich anhand von Beispielen beschrieben, bei denen die Verriegelungsrichtung der Befestigungselemente parallel zu der Querrichtung (y-Richtung) verläuft. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung auch vorgesehen sein kann, dass die Verriegelungsrichtung eine beliebige andere Ausrichtung quer zur Höhenrichtung aufweist. Insbesondere kann die Verriegelungsrichtung beispielsweise auch parallel zu der Längsrichtung (x-Richtung) verlaufen.The present invention has been described above exclusively by way of examples in which the locking direction of the fastening elements is parallel to the transverse direction (y-direction). It is understood, however, that in other variants of the invention can also be provided that the locking direction has any other orientation transverse to the height direction. In particular, the locking direction can also run, for example, parallel to the longitudinal direction (x-direction).

Die vorliegende Erfindung wurde vorstehend weiterhin ausschließlich anhand von Beispielen für Schienenfahrzeuge beschrieben. Es versteht sich jedoch, dass die Erfindung auch in Verbindung mit beliebigen anderen Fahrzeugen zum Einsatz kommen kann.The present invention has been described above solely by means of examples of rail vehicles. It is understood, however, that the invention may also be used in conjunction with any other vehicles.
