Description

Die Erfindung betrifft eine Bodengruppe für einen Schienenfahrzeugwagenkasten mit in Wagenkastenlängsrichtung verlaufenden Wandungen, zwischen denen ein Gang gebildet ist und eine sich zwischen den Wandungen erstreckende Bodenplatte, sowie einen Schienenfahrzeugwagenkasten mit einer solchen Bodengruppe und einem Schienenfahrzeug mit einer solchen Bodengruppe.The invention relates to a floor assembly for a rail vehicle car body extending in Wagenboxlängsrichtung walls between which a corridor is formed and extending between the walls floor plate, and a rail vehicle car body with such a floor assembly and a rail vehicle with such a floor assembly.

Bei schienengebundenen Fahrzeugen wird der Ausdrehwinkel von Drehgestellen hauptsächlich von zwei Parametern bestimmt, dem Drehzapfenabstand und dem Radius des kleinsten zu befahrenden Gleisbogens. Bei Niederflur-Straßenbahnen, die sich dadurch auszeichnen, dass die Höhe des Fußbodens niedriger als der Raddurchmesser ist, wird durch die Komponenten des Drehgestells, wie Räder und Rahmen, die nutzbare Gangbreite im Innenraum eingeschränkt, je größer der Ausdrehwinkel ist. Ein Gang wird beispielsweise zwischen Radkästen gebildet.For rail vehicles, the turnout angle of bogies is mainly determined by two parameters, the pivot distance and the radius of the smallest track curve to be traveled. For low-floor trams, which are characterized in that the height of the floor is lower than the wheel diameter, the components of the bogie, such as wheels and frames, the usable aisle width in the interior is limited, the greater the angle of turn. A gear is formed for example between wheel arches.

EP1686033A2 betrifft ein Untergestell eines Fahrwerkmoduls für Niederflur-Schienenfahrzeuge, mit zumindest einer unteren Bodenplatte sowie in Fahrzeuglängsrichtung verlaufenden seitlichen Wandungen, die Radkästen für Räder eines Fahrwerks bilden. EP1686033A2 relates to a base of a chassis module for low-floor rail vehicles, with at least one lower base plate and running in the vehicle longitudinal direction side walls that form wheel arches for wheels of a chassis.

Zur Erhöhung des Passagierkomforts ist es erwünscht, möglichst große oder eine maximale Gangbreite zu erzielen. Andererseits besteht bei Fahrzeugen, die in Strecken mit verschiedenen Gleisbogenradien betrieben werden sollen, die Notwendigkeit, den jeweils kleinsten Radius für die Konstruktion der tragenden Wagenkastenstruktur bzw. der Bodengruppe zugrunde zu legen. Dadurch wird auf den Schienennetzen mit größeren Gleisbogenradien die Gangbreite unnötig eingeschränkt. Dies könnte umgangen werden, indem je nach Kunde und je nach Gegebenheiten des Schienennetzes die Wagenkastenstruktur neu gestaltet wird, was aber erhebliche Aufwendungen verursacht.To increase the passenger comfort, it is desirable to achieve the greatest possible or maximum aisle width. On the other hand, vehicles that are to be operated on routes with different track curve radii, the need to use the smallest radius for the construction of the supporting car body structure or the ground group. As a result, the passage width is unnecessarily limited on the rail networks with larger track radius. This could be circumvented by redesigning the car body structure depending on the customer and the circumstances of the rail network, which, however, causes considerable expenses.

Aufgabe der Erfindung ist es, für dieses Problem eine Lösung anzugeben.The object of the invention is to provide a solution to this problem.

Nach einer grundlegenden Idee der Erfindung wird eine tragende Struktur des Wagenkastens, insbesondere eine Bodengruppe des Wagenkastens so gestaltet, dass eine maximale Gangbreite unabhängig vom Ausdrehwinkel eines Fahrwerks oder Fahrwerksteilen, wie Drehgestell, Achse oder Rädern, erreicht werden kann. Die Bodengruppe weist in einem oder mehreren Bereichen, der/die für das Ausdrehen von diesen Komponenten erforderlich ist, kein Material auf. Somit weist die Bodengruppe Aussparungen auf, die Fahrwerksteile bei einer Lenkbewegung durchdringen können, ohne mit der Bodengruppe des Wagenlastens zu kollidieren. Der Bereich kann somit ohne Kollision mit der Bodengruppe von einem Teil eines Drehgestells, von einer Achse und/oder einem Rad durchdrungen werden, wenn eine Lenkbewegung erfolgt. Die Aussparung kann verkleidet werden. Die Aussparungen werden nur so groß gewählt, wie es für eine kollisionsfreie Ausdrehung eines Fahrwerks oder von Fahrwerksteilen erforderlich ist. In anderen Bereichen kann eine maximale Raumausnutzung für den Innenraum erfolgen, insbesondere eine maximale Gangbreite bereitgestellt werden.According to a basic idea of the invention, a load-bearing structure of the car body, in particular a bottom group of the car body is designed so that a maximum aisle width regardless of the turning angle of a chassis or Chassis parts, such as bogie, axle or wheels, can be achieved. The floor assembly does not include material in one or more areas required for the removal of these components. Thus, the bottom assembly has recesses that can penetrate chassis parts in a steering movement, without colliding with the bottom group of the car load. The area can thus be penetrated by a part of a bogie, by an axle and / or a wheel without colliding with the floor assembly when a steering movement takes place. The recess can be covered. The recesses are chosen only as large as is required for a collision-free rotation of a chassis or suspension parts. In other areas, a maximum space utilization for the interior, in particular a maximum aisle width can be provided.

Durch die Erfindung wird eine Anpassung einer Wagenkastenstruktur vermieden. Je nach Lenkwinkel können Teile des Fahrwerks die Aussparungen durchdringen oder nicht. Die Form der Aussparung ist an die baulichen Gegebenheiten des Fahrwerks leicht anpassbar.By the invention, an adaptation of a car body structure is avoided. Depending on the steering angle parts of the chassis can penetrate the recesses or not. The shape of the recess is easily adaptable to the structural conditions of the chassis.

Eine oder mehrere Aussparungen können von einem Teil des Fahrwerks durchdrungen werden, wenn das Fahrwerk eine Lenkbewegung vollzieht und dieser Teil des Fahrwerks nach innen, d.h. zur längs verlaufenden Wagenmittelachse, bewegt wird.One or more recesses may be penetrated by a portion of the landing gear when the landing gear is steering and that portion of the landing gear is inwardly, i. to the longitudinal center of the car, is moved.

Angegeben wird insbesondere eine Bodengruppe für einen Schienenfahrzeugwagenkasten, aufweisend einen Gang mit in Wagenkastenlängsrichtung verlaufenden seitlichen Wandungen, wobei die seitlichen Wandungen Aussparungen aufweisen, die jeweils von einem Teil eines Fahrwerks, insbesondere eines Drehgestells, einer Achse und/oder eines Rades durchdrungen werden können, wenn das Fahrwerk eine Lenkbewegung vollzieht.Specified is in particular a floor assembly for a railcar box, comprising a corridor extending in Wagenboxlängsrichtung lateral walls, the side walls have recesses, which can be penetrated by a part of a chassis, in particular a bogie, an axle and / or a wheel, if the chassis performs a steering movement.

Die seitlichen Wandungen, auch bezeichnet als Seitenwände der Bodengruppe, können durch ein oder mehrere Verbindungselemente verbunden sein, beispielsweise einen Träger, oder auf eine Unterbodenstruktur, beispielsweise eine Trägerstruktur aufgebracht sein.The lateral walls, also referred to as side walls of the floor assembly, can be connected by one or more connecting elements, for example a carrier, or be applied to an underbody structure, for example a carrier structure.

Die seitlichen Wandungen erstrecken sich in Wagenkastenlängsrichtung (X-Richtung) und in Wagenkasten-Hochrichtung (Z-Richtung). Ausgehend von dem Boden des Gangs erstrecken sich die seitlichen Wandungen nach oben. Der Gang ist zwischen den seitlichen Wandungen gebildet. Der Gang liegt zwischen den seitlichen Wandungen. Der Gang wird durch die seitlichen Wandungen begrenzt.The side walls extend in the carbody longitudinal direction (X-direction) and in the car body vertical direction (Z-direction). Starting from the floor of the corridor, the lateral walls extend upwards. The corridor is between the formed lateral walls. The corridor lies between the lateral walls. The passage is limited by the lateral walls.

An den oberen Rand der seitlichen Wandungen kann sich jeweils eine obere Abdeckplatte anschließen, die im Wesentlichen horizontal verlaufen kann. An den vorderen Rand der seitlichen Wandungen kann sich jeweils eine vordere Abdeckplatte anschließen. An den hinteren Rand der seitlichen Wandungen kann sich jeweils eine hintere Abdeckplatte anschließen. Eine seitliche Wandung und eine obere Abdeckplatte bilden einen Radkasten, der um vordere und hintere Abdeckplatte ergänzt sein kann.At the upper edge of the side walls can each be followed by an upper cover plate, which can extend substantially horizontally. At the front edge of the side walls can each connect a front cover plate. At the rear edge of the side walls can each connect a rear cover plate. A side wall and an upper cover plate form a wheel arch, which can be supplemented by front and rear cover plate.

Ein erwähnter Gang kann zwischen zumindest zwei Radkästen gebildet sein. Die Radkästen liegen in Längsrichtung des Fahrzeugs rechts und links. Die Radkästen grenzen nach außen hin an den Gang an. Vorzugsweise ist sind vier Radkästen vorhanden, von denen in Längsrichtung des Fahrzeugs zwei rechts liegen (rechte Radkästen) und zwei links (linke Radkästen). Zwischen den rechten Radkästen und den linken Radkästen verläuft der Gang.A mentioned gear can be formed between at least two wheel arches. The wheel arches lie in the longitudinal direction of the vehicle right and left. The wheel arches border outside to the corridor. Preferably there are four wheel arches, two of which are to the right in the longitudinal direction of the vehicle (right wheel arches) and two left (left wheel arches). The corridor runs between the right-hand wheel arches and the left-hand wheel arches.

Der Gang ist vorzugsweise ein mittig verlaufender Gang, d.h. ein mittig in der Bodengruppe verlaufender Gang.The passage is preferably a central passage, i. a passage in the middle of the floor group.

Die Bodengruppe kann eine Bodenplatte aufweisen, die zwischen den seitlichen Wandungen angeordnet ist. Die Bodenplatte bildet den Boden des Gangs.The floor assembly may include a floor panel disposed between the side walls. The bottom plate forms the floor of the aisle.

Die Bodenplatte kann als verbindendes Element der seitlichen Wandungen ausgestaltet sein.The bottom plate may be configured as a connecting element of the lateral walls.

Die Aussparungen können eine abgerundete Kontur aufweisen. Die Aussparungen können an die Form oder Kontur eines durchdringenden Fahrwerksteils angepasst sein.The recesses may have a rounded contour. The recesses may be adapted to the shape or contour of a penetrating chassis part.

Aussparungen sind vorzugsweise paarweise einander gegenüberliegend an gegenüberliegenden Wandungen angeordnet. Insbesondere sind zwei Paare an dem Gang gegenüberliegende Aussparungen vorhanden. Die beiden Paare sind in Fahrzeuglängsrichtung voneinander beabstandet. Eine solche Anordnung ist insbesondere anwendbar für ein Fahrwerk, insbesondere ein Drehgestell, das zwei Paare gegenüberliegende Räder aufweist.Recesses are preferably arranged in pairs opposite one another on opposite walls. In particular, there are two pairs of recesses opposite the passage. The two pairs are spaced apart in the vehicle longitudinal direction. Such an arrangement is particularly applicable to a chassis, in particular a bogie having two pairs of opposed wheels.

In einer Ausführungsform werden diagonal gegenüberliegende Aussparungen jeweils von einem Teil eines Fahrwerks durchdrungen, wenn das Fahrwerk eine Lenkbewegung vollzieht. Bei einer Lenkung des Fahrwerks nach links sind dies eine Aussparung vorne rechts (d.h. in Fahrzeuglängsrichtung rechte Aussparung eines in Fahrzeuglängsrichtung vorderen, in Querrichtung gegenüberliegenden Paars Aussparungen) und eine Aussparung hinten links (d.h. in Fahrzeuglängsrichtung linke Aussparung eines in Fahrzeuglängsrichtung hinteren, in Querrichtung gegenüberliegenden Paars Aussparungen). Bei einer Lenkung nach rechts sind dies eine Aussparung vorne links (d.h. in Fahrzeuglängsrichtung linke Aussparung des in Fahrzeuglängsrichtung vorderen Paars Aussparungen) und eine Aussparung hinten rechts (d.h. in Fahrzeuglängsrichtung rechte Aussparung des in Fahrzeuglängsrichtung hinteren Paars Aussparungen).In one embodiment, diagonally opposite recesses are each penetrated by a part of a chassis when the chassis performs a steering movement. In a steering of the chassis to the left, these are a recess in the front right (ie in the vehicle longitudinal direction right recess front in the vehicle longitudinal direction, transversely opposite pair of recesses) and a recess in the left rear (ie in the vehicle longitudinal left recess of a vehicle longitudinally rear, transversely opposite pair recesses). In a steering to the right, these are a front left recess (i.e., left-hand recess in the vehicle longitudinal direction of the pair of recesses) and a rear-right recess (that is, a recess in the vehicle longitudinal direction of the rear pair of recesses in the vehicle longitudinal direction).

In einer Ausführungsform weist die Bodengruppe Abdeckelemente auf, die jeweils an einer der seitlichen Wandungen befestigt sind und die jeweils eine Aussparung abdecken. Die Abdeckelemente können als Abdeckkappen oder Abdeckplatten gestaltet sein. Die Abdeckelemente können insbesondere form- und/oder kraftschlüssig mit den Wandungen verbunden sein.In one embodiment, the bottom group on cover elements, which are each attached to one of the lateral walls and each cover a recess. The cover elements can be designed as cover caps or cover plates. The cover elements may in particular be positively and / or non-positively connected to the walls.

Abdeckelemente allgemein dienen zum Schutz von Fahrgästen und zur Verdeckung von Fahrwerksteilen. Die Abdeckelemente werden auch als Verkleidungselemente oder Verkleidungen bezeichnet.Covering elements generally serve to protect passengers and to cover chassis parts. The cover elements are also referred to as cladding elements or panels.

Die Abdeckelemente sind vorzugsweise nicht mittragende oder mittragende, d.h. die Wagenkastenstruktur nicht verstärkende Elemente. Anders ausgedrückt weisen hierbei die Abdeckelemente keine tragende Funktion für die Struktur des Wagenkastens auf. Die Abdeckelemente können aus Metall, Kunststoff oder einem Verbundstoff sein. Erwähnte seitliche Wandungen bzw. Seitenwände sind vorzugsweise tragende Elemente.The cover members are preferably non-co-bearing or co-bearing, i. the car body structure non-reinforcing elements. In other words, the cover elements have no supporting function for the structure of the car body. The cover elements may be made of metal, plastic or a composite material. Mentioned lateral walls or side walls are preferably load-bearing elements.

In einer speziellen Ausführungsform sind genannte Abdeckelemente so ausgestaltet, dass zwischen jeweils einer Aussparung und einem Abdeckelement ein Hohlraum gebildet ist. Abdeckelemente, bei denen solch ein Hohlraum gebildet wird, sind vorteilhaft, wenn Teile des Fahrwerks in die Aussparung im Fall einer Lenkbewegung eingreifen bzw. diese durchdringen. In dieser Ausführungsform ragt das Abdeckelement in den Gang hinein. In dieser Ausführungsform erstreckt sich das Abdeckelement von einer seitlichen Wandung, an dem es angebracht ist, in Richtung der gegenüber liegenden seitlichen Wandung. Der Hohlraum ist durch die Aussparung zugänglich, also auf Seite der Aussparung offen. In den Hohlraum kann ein Teil eines Fahrwerks, wie einer Drehgestells, einer Achse und/oder eines Rades, eingreifen bzw. hineinbewegt werden.In a specific embodiment, said cover elements are configured such that a cavity is formed between a respective recess and a cover element. Covering elements in which such a cavity is formed, are advantageous if parts of the chassis engage in the recess in the case of a steering movement or penetrate it. In this embodiment, the cover protrudes into the passage. In this embodiment, the cover member extends from a side wall, to which it is attached, in the direction of the opposite lateral wall. The cavity is accessible through the recess, so open on the side of the recess. In The cavity may be a part of a chassis, such as a bogie, an axle and / or a wheel, engage or be moved.

Genannte Abdeckelemente sind vorzugsweise abnehmbar, d.h. demontierbar, und vorzugsweise durch anders gestaltete Abdeckelemente austauschbar. Insbesondere sind Abdeckelemente durch anders gestaltete Abdeckelemente austauschbar, die einen größeren oder kleineren Hohlraum zwischen Aussparung und Abdeckelement bilden. Sollten kundenspezifisch größere Ausdrehwinkel eines Fahrwerks notwendig sein, beispielsweise bei Strecken mit kleineren Kurvenradien, kann das Abdeckelement durch ein solches ersetzt werden, das einen größeren Hohlraum zur Verfügung stellt, da Fahrwerksteile weiter in die Aussparung eingreifen. Durch die Austauschbarkeit von Abdeckelementen entfällt ein aufwendiges Anpassen der Wagenkastenstruktur. Es muss lediglich in Kauf genommen werde, dass die Gangbreite im Bereich der Abdeckelemente je nach Gestaltung mehr oder weniger verringert ist.Said cover elements are preferably removable, i. removable, and preferably interchangeable by differently shaped cover. In particular, cover elements are exchangeable by differently shaped cover elements, which form a larger or smaller cavity between recess and cover. Should customer specific larger turnout of a chassis be necessary, for example, in routes with smaller curve radii, the cover can be replaced by one that provides a larger cavity available because chassis parts continue to engage in the recess. Due to the interchangeability of cover elements eliminates a costly customization of the car body structure. It must be accepted only that the passage width in the area of the cover is more or less reduced depending on the design.

Die in Fig. 1 gezeigte Bodengruppe 1 weist die Radkästen 2, 3 auf. Die Radkästen 2, 3 sind durch eine Querträgerstruktur 4 verbunden. Die Radkästen 2, 3 weisen die Seitenwände 5, 6, die oberen Abdeckplatten 30a, 30b, 30c (Radkasten 3), 30d, 30e, 30f (Radkasten 2), die vordere Abdeckplatte 31 und die hintere Abdeckplatte 32 (nur für Radkasten 2 gezeigt) auf.In the Fig. 1 Floor group 1 shown has the wheel arches 2, 3. The wheel arches 2, 3 are connected by a cross member structure 4. The wheel arches 2, 3 have the side walls 5, 6, the top cover plates 30a, 30b, 30c (wheel arch 3), 30d, 30e, 30f (wheel arch 2), the front cover plate 31 and the rear cover plate 32 (only shown for wheel arch 2) ) on.

Die seitliche Wandung 6 ist perspektivisch verdeckt und daher gestrichelt eingezeichnet.The lateral wall 6 is hidden in perspective and therefore shown in dashed lines.

In der Seitenwand 5 sind die Aussparungen 7, 8 ausgebildet, die in etwa halbkreisförmig ausgebildet sind. In analoger Weise sind in der Seitenwand 6 die Aussparungen 9, 10 ausgebildet.In the side wall 5, the recesses 7, 8 are formed, which are formed approximately semicircular. In an analogous manner, the recesses 9, 10 are formed in the side wall 6.

Am hinteren Ende schließt sich an die Radkästen 2, 3 eine Unterbauträgerstruktur 11 an, gebildet aus Längsträgern 11a und Querträgern 11b.At the rear end adjoins the wheel arches 2, 3 a substructure support structure 11, formed of longitudinal members 11a and cross members 11b.

In Fig. 2 sind auf die in Fig. 1 gezeigte Trägerstruktur Bodenplatten 12, 13 aufgebracht. Zwischen den Seitenwänden 5, 6, von denen in Fig. 2 nur die Seitenwand 5 gezeigt ist, ist ein Gang gebildet.In Fig. 2 are on the in Fig. 1 shown support structure bottom plates 12, 13 applied. Between the side walls 5, 6, of which in Fig. 2 only the side wall 5 is shown, a passage is formed.

Weiterhin unter der Bodengruppe 1 ein Drehgestell 14 angeordnet, das in Fahrtrichtung (Pfeil X) leicht nach rechts eingelenkt ist.Furthermore, a bogie 14 arranged below the floor assembly 1, which is slightly deflected in the direction of travel (arrow X) to the right.

Von dem Drehgestell sind die Räder 15, 16 sichtbar, während den Rädern 15, 16 gegenüberliegende Räder von den Radkästen 2, 3 verdeckt sind.Of the bogie wheels 15, 16 are visible, while the wheels 15, 16 opposite wheels of the wheel arches 2, 3 are hidden.

Durch die Lenkbewegung wird die Radnabe 17 des vom Radkasten 3 verdeckten Rades durch die Aussparung 7 hindurch und damit durch die Seitenwand 5 hindurch bewegt, was in Fig. 4 noch detaillierter dargestellt ist. Somit wird durch die Aussparungen 7, 8, 9, 10 ein Lenkwinkel ermöglicht, der größer ist, als es der Abstand der Seitenwände 5, 6 (ohne Aussparungen) an sich zulässt. In der Bodenplatte 12 sind ebenfalls Aussparungen 18, 19 (und gegenüberliegende nicht gezeigte Aussparungen, die perspektivisch verdeckt sind) gebildet.Due to the steering movement, the wheel hub 17 of the concealed wheel 3 by the wheel through the recess 7 and thus through the side wall 5 is moved through what in Fig. 4 is shown in more detail. Thus, through the recesses 7, 8, 9, 10 allows a steering angle which is greater than the distance between the side walls 5, 6 (without recesses) per se permits. In the bottom plate 12 are also recesses 18, 19 (and opposite recesses not shown, which are hidden in perspective) formed.

Die Aussparungen 7, 8, 9, 10 in den Seitenwänden 5, 6 sowie Aussparungen 18, 19 (und weitere) in der Bodenplatte 12 sind so dimensioniert, dass auch bei maximalem Lenkeinschlag des Drehgestells 14 keine Teile des Drehgestells mit den Seitenwänden 5, 6 oder der Bodenplatte 12 in Berührung kommen.The recesses 7, 8, 9, 10 in the side walls 5, 6 and recesses 18, 19 (and others) in the bottom plate 12 are dimensioned so that even at maximum steering angle of the bogie 14 no parts of the bogie with the side walls 5, 6 or the bottom plate 12 come into contact.

In Fig. 3 ist eine Ansicht der Bodengruppe mit Drehgestell zu sehen, wobei im Vergleich zu Fig. 2 die Bodenplatte 12 entfernt ist. Das Drehgestell 14 ist über den Drehkranz 20 angelenkt, der an der Trägerstruktur 4 angebracht ist.In Fig. 3 is a view of the underbody with bogie to see, compared to Fig. 2 the bottom plate 12 is removed. The bogie 14 is articulated about the turntable 20 which is attached to the support structure 4.

Sichtbar sind von dem Drehgestell wiederum das vordere rechte Rad 15. Dadurch, dass die Bodenplatte 12 nicht abgebildet ist, sind die vordere Achse 22 und die hintere Achse 23 sichtbar.Visible are in turn from the bogie, the front right wheel 15. Due to the fact that the bottom plate 12 is not shown, the front axle 22 and the rear axle 23 are visible.

Im Unterschied zu Fig. 2 ist die Aussparung 7 (und weitere Öffnungen 8, 9, 10) mit dem Abdeckelement 24 verdeckt, das als Abdeckkappe ausgebildet und auf die Seitenwand 5 der Bodengruppe 1 aufgesetzt ist. Durch die Ausstülpung des Abdeckelements 24 in Richtung Gang, weg von der Seitenwand 5, wird zwischen der Aussparung 7 und dem Abdeckelement 24 ein Hohlraum gebildet, in den die in Fig. 2 gezeigte Radnabe 17 eingreifen kann.In contrast to Fig. 2 is the recess 7 (and other openings 8, 9, 10) covered with the cover 24, which is designed as a cap and placed on the side wall 5 of the bottom group 1. By the protuberance of the cover 24 in the direction of gear, away from the side wall 5, is between the recess 7 and the Cover member 24, a cavity formed in the in Fig. 2 shown wheel hub 17 can engage.

Diese Situation ist detailliert in Fig. 4 in einer Ansicht von unten dargestellt. Das in Fig. 2 und Fig. 3 von dem Radkasten 3 verdeckte Rad 25 ist sichtbar. Die Radnabe 17 durchdringt aufgrund der Einlenkbewegung die Seitenwand 5 und greift in die Aussparung 7 ein. Die Öffnung ist wiederum durch die Abdeckkappe 24 verdeckt. Die Abdeckkappe 24 ist auf die Seitenwand 5 aufgeschraubt mittels Schraubverbindungen 26 an dem Flansch 27. Dadurch ist die Abdeckkappe 24 austauschbar, kann beispielsweise durch eine weniger in den Gang zwischen den Seitenwänden 5, 6 hereinragende Abdeckkappe ersetzt werden, wenn der geforderte maximale Einlenkwinkel des Drehgestells 14 geringer ist und dadurch die Radnabe 17 die Aussparung 7 weniger durchdringt. Es versteht sich, dass an den in Fig. 1 gezeigten Aussparungen 8, 9, 10 ebenfalls Abdeckkappen angebracht sein können.This situation is detailed in Fig. 4 shown in a view from below. This in Fig. 2 and Fig. 3 from the wheel arch 3 hidden wheel 25 is visible. The wheel hub 17 penetrates due to the Einlenkbewegung the side wall 5 and engages in the recess 7 a. The opening is in turn covered by the cap 24. The cap 24 is screwed onto the side wall 5 by means of screw 26 on the flange 27. Thus, the cap 24 is replaceable, for example, by a less in the corridor between the side walls 5, 6 protruding cap are replaced when the required maximum Einlenkwinkel the bogie 14 is smaller and thereby the hub 17 penetrates the recess 7 less. It is understood that to the in Fig. 1 shown recesses 8, 9, 10 may also be mounted cover caps.
