Description

Die Erfindung betrifft ein Schienenfahrzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a rail vehicle with the features of the preamble of claim 1.

Mehrteilige Nahverkehrszüge weisen im allgemeinen keinen, oder einen nur in Notfällen begehbaren Übergang zwischen den einzelnen Wagenkästen auf, oder sind mit den bei Vollbahnfahrzeugen üblichen, mit Faltenbalg und Gummiwulst geschützten Übergang mit Klappbrücken im Fußbodenbereich ausgerüstet.Multi-part commuter trains generally have no, or only a transition between the individual car bodies that can be walked in emergencies, or are equipped with the transition with bellows and rubber bulge, which is common in full-track vehicles, with bascule bridges in the floor area.

Bei kurzgekuppelten, vierachsigen Wageneinheiten ist hierbei ein Querversatz der Stirnwände in Kauf zu nehmen, der beim Befahren von Gegenbögen auftritt und die konstruktiv mögliche nutzbare Breite des Übergangs einschränkt.In the case of short-coupled, four-axle carriage units, a transverse offset of the end walls must be taken into account, which occurs when driving through counter arches and limits the constructively possible usable width of the transition.

Bei Gliederzügen der Jakobs-Bauart sind die benachbarten Wagenkästen auf einem gemeinsamen Drehgestell gelagert, wobei im allgemeinen jedem der Wagenkästen ein eigener Drehzapfen oder Koppelpunkt und ein eigenes Sekundärfedersystem zugeordnet ist. Hierdurch werden Relativbewegungen der Wagenkästen zueinander auf die Sekundärebenen-Querspiele reduziert, die jedoch bei gegenläufigen Bewegungen der Wagenkästen noch in einer Größenordnung von 80 - 100 mm liegen können. Die Ausbildung eines durchgehend in gleicher Ebene begehbaren Fußbodens ist damit erschwert.In Jakobs-type articulated trains, the adjacent car bodies are mounted on a common bogie, with each of the car bodies generally being assigned its own pivot or coupling point and its own secondary spring system. As a result, relative movements of the car bodies with respect to one another are reduced to the secondary-plane transverse play, which, however, can still be in the order of 80-100 mm when the car bodies move in opposite directions. This makes it difficult to form a floor that can be walked on at the same level throughout.

Die mechanische Koppelung der Wagenkästen direkt oder indirekt über das Drehgestell hat einen erheblichen Einfluß auf die Dynamik des Zugsystems.The mechanical coupling of the car bodies directly or indirectly via the bogie has a considerable influence on the dynamics of the train system.

Querkräfte aus der Eigendynamik der Wagenkästen beeinflussen über die erforderlichen Querspiele in der Sekundärebene und der außermittigen Lage der Queranschläge die Querdynamik des Laufwerkes.Lateral forces from the inherent dynamics of the car bodies influence the lateral dynamics of the running gear via the required lateral play in the secondary level and the eccentric position of the lateral stops.

Die Nachteile des Prinzips sind auch in umgkehrter Richtung wirksam. Wird das Querspiel der Wagenkästen zum Erreichen einer größtmöglichen Übergangsbreite eingeschränkt, führen schon relativ geringe laterale Störungen der Gleislage zu einer Auslenkung der Wagenkästen und können so ein Schlingern der gesamten Wagenkette anregen.The disadvantages of the principle are also effective in the opposite direction. If the transverse play of the car bodies is restricted in order to achieve the greatest possible transition width, even relatively minor lateral disturbances in the track position lead to a deflection of the car bodies and can thus stimulate the entire car chain to lurch.

Die Übertragung von Längskräften erfolgt im allgemeinen in einer gegenüber dem Untergestell versetzten Ebene. Koppelelemente endlicher Länge, z.B. Zug-Druck-Stangen oder der Drehgestellrahmen selbst, reagieren bei Auftreten von Traktions- und Stoßkräften instabil. Liegt eine ungleiche Verteilung der Traktionskräfte innerhalb des Zugverbandes vor, wie dies z.B. bei einer Achsfolge Bo'+Bo'+2'+Bo'+Bo' der Fall ist, werden stets Anteile, im genannten Beispiel 25%, der auftretenden Traktionskräfte über die jeweils äußeren Koppelelemente übertragen. Im Fall eines Auflaufstoßes wird durch das Koppelelement ein Versatz der Wagenenden sowohl in lateraler, wie in vertikaler Richtung erzwungen. Da für einen möglichst breiten Übergang die Endsäulen der Wagenkästen nahe der Seitenwandebene liegen müssen, kann im Falle eines Unfalls der Gefahr des Teleskopierens nicht wirksam begegnet werden.Longitudinal forces are generally transmitted in a plane offset from the base. Coupling elements of finite length, e.g. Push-pull rods or the bogie frame itself, react unstably when traction and impact forces occur. If there is an uneven distribution of traction forces within the train set, e.g. in the case of an axis sequence Bo '+ Bo' + 2 '+ Bo' + Bo ', portions, in the example mentioned 25%, of the traction forces that occur are always transmitted via the respective outer coupling elements. In the event of an impact, the coupling element forces the ends of the carriage to move in both the lateral and vertical directions. Since the end pillars of the car bodies must be close to the side wall level for the widest possible transition, the risk of telescoping cannot be effectively counteracted in the event of an accident.

Sowohl die Koppelelemente, wie auch die doppelte Anordnung der Sekundärfederung beeinträchtigen den Einbauraum innerhalb des gemeinsamen Drehgestells erheblich und erschweren oder verhindern dessen Ausführung als Triebdrehgestell.Both the coupling elements and the double arrangement of the secondary suspension significantly impair the installation space within the common bogie and make it difficult or impossible to implement it as a powered bogie.

Aufgabe der Erfindung ist es, ein Schienenfahrzeug als Gelenkzug so auszuführen, daß es auf voller Länge in voller Breite ohne wesentliche Einschränkung begehbar, bzw. einsehbar ist, bei dem die Wagenkästen in üblicher Weise weitestgehend vom Laufwerk entkoppelt sind, bei dem Längsdruckkräfte in üblicher Größenordnung übertragen werden können, bei dem ein Ineinanderschieben der offenen Wagenkastenenden bei Unfällen verhindert wird und bei dem eine beliebige Anzahl von Drehgestellen mit Antrieben ausgerüstet werden kann.The object of the invention is to design a rail vehicle as an articulated train in such a way that it can be walked or viewed over its entire length in its full width without significant restriction, in which the car bodies are largely decoupled from the drive in the usual way, with the longitudinal compressive forces of the usual order can be transmitted, in which a pushing together of the open ends of the car body is prevented in the event of an accident and in which any number of bogies can be equipped with drives.

Diese Aufgabe wird mit den im kennzeichnenden Teil des Anspruchs 1 genannten Merkmalen gelöst. Fortbildungen und besondere Ausführungen der Erfindung sind in den weiteren Ansprüchen umfaßt.This object is achieved with the features mentioned in the characterizing part of claim 1. Developments and special embodiments of the invention are included in the further claims.

Erfindungsgemäß ist zwischen den mindestens zwei Wagenkästen eines Schienenfahrzeugs ein Zwischenstück angeordnet, wobei der eine Wagenkasten an dem Zwischenstück um eine Querachse und der andere Wagenkasten an dem Zwischenstück um eine Hochachse drehbar gelagert ist.According to the invention, an intermediate piece is arranged between the at least two car bodies of a rail vehicle, one car body being mounted on the intermediate piece about a transverse axis and the other car body on the intermediate piece being rotatable about a vertical axis.

Die Lagerungen für die Wagenkästen am Zwischenstück sind vorteilhafterweise in Verwindungsrichtung elastisch ausgeführt.The bearings for the car bodies on the intermediate piece are advantageously designed to be elastic in the twisting direction.

Nach einer bevorzugten Ausführung der Erfindung weisen die Untergestelle der Wagenkästen unterhalb des Zwischenstücks mittige, gegeneinander zentrierte Anschläge auf.According to a preferred embodiment of the invention, the underframes of the car bodies have stops which are centered and centered against one another below the intermediate piece.

Nach einer weiteren bevorzugten Ausführung der Erfindung ist der Wagenkasten, der an dem Zwischenstück um eine Hochachse drehbar gelagert ist, in einem oberen Bereich mittels eines Lenkers mit dem Zwischenstück verbunden, wobei der Lenker vorzugsweise beidseitig kardanisch elastisch gelagert ist.According to a further preferred embodiment of the invention, the car body, which is mounted on the intermediate piece so as to be rotatable about a vertical axis, is connected in an upper region to the intermediate piece by means of a link, the link preferably being gimbally elastically mounted on both sides.

Nach einer bevorzugten Ausführungsform ist der eine Wagenkasten mit an seiner unteren Ebene in Richtung auf das Zwischenstück auskragenden Armen und an diesen angeordneten Lagerbuchsen in einer quer zum Wagenkasten liegenden horizontalen Achse mit Lagerböcken an, unter oder auf der unteren Ebene des Zwischenstücks und der andere Wagenkasten mit an seiner unteren Ebene in Richtung auf das Zwischenstück auskragenden Armen mit einem mittig auf oder unter der unteren Ebene des Zwischenstücks angeordneten Drehelement verbunden.According to a preferred embodiment, the one car body with arms projecting at its lower level towards the intermediate piece and bearing bushes arranged thereon in a horizontal axis lying transversely to the car body with bearing blocks on, below or on the lower level of the intermediate piece and the other car body with connected at its lower level in the direction of the intermediate arm projecting with a rotating element arranged centrally on or below the lower level of the intermediate piece.

Das Drehelement ist vorzugsweise ein vorgespanntes Kreuzrollenlager und vorteilhafterweise liegen die Drehpunkte beider Wagenkästen bei Geradeausfahrt in einer Ebene.The rotating element is preferably a preloaded crossed roller bearing and advantageously the pivots of both car bodies lie in one plane when driving straight ahead.

Zur Erzielung einer größtmöglichen, niveaugleich begehbaren Breite des Innenraums im Übergangsbereich, ist die direkte oder indirekte gemeinsame Abstützung zweier benachbarter Wagenkästen auf einem Drehgestell Voraussetzung, um Relativbewegungen beim Befahren von Gegenbögen, Kuppen und Senken auszuschließen. Eine weitere Voraussetzung ist eine gelenkige Verbindung der beiden Wagenkästen in der Form, daß Hoch- und Querachse des Gelenkes einen gemeinsamen Schnittpunkt nahe der Fußbodenoberkante aufweisen.In order to achieve the greatest possible width of the interior that can be walked on at the same level in the transition area, the direct or indirect joint support of two adjacent car bodies on a bogie is a prerequisite in order to exclude relative movements when driving through counter bends, crests and depressions. Another requirement is an articulated connection of the two car bodies in such a way that the vertical and transverse axes of the joint have a common intersection near the top edge of the floor.

Zur Verringerung der zu überbrückenden Winkel zwischen den Wagenkästen ist es zweckmäßig, ein Zwischenstück, z.B. in Form eines Zwischenstückes einzufügen, das durch Einstellmechanismen oder Federelemente winkelhalbierend geführt wird oder so angelenkt ist, daß die aus Bogenfahrt und Kuppen-/Senkenfahrt resultierenden Winkel je einem der beiden Übergangsbereiche zugeordnet werden. Damit wird bei Anordnung von Faltenbälgen eine Minimierung der Anzahl der Falten erreicht, da die Bälge nur für eine einfache, nicht jedoch für eine kombinierte Bewegung zwischen den Wagenkästen ausgelegt werden können.To reduce the angles to be bridged between the car bodies, it is advisable to insert an intermediate piece, e.g. in the form of an intermediate piece, which is guided in half-angle by adjusting mechanisms or spring elements or is articulated in such a way that the angles resulting from curved travel and crest / lower travel each one of the be assigned to both transition areas. In this way, the number of folds is minimized when bellows are arranged, since the bellows are only for a simple one, but not for a combined one Movement between the car bodies can be designed.

Um eine derartige Aufteilung der Winkelbewegungen zu erreichen, wird einer der beiden Wagenkästen über zwei außen liegende Kragarme, in die großvolumige Elastomerbuchsen formschlüssig eingepreßt sind, auf dem Querträger des Zwischenstückes gelagert.In order to achieve such a division of the angular movements, one of the two car bodies is mounted on the crossbeam of the intermediate piece via two cantilevers on the outside, into which large-volume elastomer bushings are pressed in a form-fitting manner.

Der zweite Wagenkasten wird über zwei innen liegende Kragarme mit eingepreßten Elastomerbuchsen auf einem Drehelement, vorzugsweise einem vorgespannten Kreuzrollenlager, gelagert, das seinerseits zentral auf dem Querträger des Zwischenstückes angeordnet ist. Das Zwischenstück wird über einen Lenker, der an beiden Enden elastisch gelagert ist, gegenüber dem Wagenkasten stabilisiert.The second car body is mounted on two internal cantilever arms with pressed-in elastomer bushings on a rotating element, preferably a preloaded cross roller bearing, which in turn is arranged centrally on the cross member of the intermediate piece. The intermediate piece is stabilized against the car body via a handlebar, which is elastically supported at both ends.

Ist es aufgrund extrem kleiner Ausrundungsradien erforderlich, das Zwischenstück um die Querachse winkelhalbierend zu führen, kann der Lenker durch ein Gestänge ersetzt werden, das die Relativbewegungen in x-Richtung zwischen beiden Wagenkästen erfaßt und deren halben Betrag dem Zwischenstück übermittelt.If it is necessary due to extremely small radius of curvature to guide the intermediate piece bisecting the transverse axis, the handlebar can be replaced by a linkage that detects the relative movements in the x-direction between the two car bodies and transmits half of the amount to the intermediate piece.

Die für beide Wagenkästen identischen, bei Stellung im geraden Gleis in einer Achse liegenden Elastomerbuchsen sind so dimensioniert, daß sie Auflast, Querkraft und Verwindung der Wagenkästen gegeneinander übertragen können.The elastomer bushings, which are identical for both car bodies and are positioned in one axis when positioned on a straight track, are dimensioned such that they can transmit the load, transverse force and torsion of the car bodies against one another.

Um für die erforderlichen Federwege eine ausreichende Vorspannung des Gummivolumens in den Elastomerbuchsen zu erreichen, werden diese zweckmäßig so ausgeführt, daß der Gummi am Befestigungsbolzen vulkanisiert ist und beim Einpressen in eine Bohrung der Kragarme die erforderliche Vorspannung erfährt. Die Arretierung der Elastomerbuchse erfolgt zweckmäßigerweise über deren Formgebung und eine dieser angepaßten Kontur der Bohrung.In order to achieve sufficient prestressing of the rubber volume in the elastomer bushings for the required spring travel, these are expediently designed such that the rubber on the fastening bolt is vulcanized and experiences the required prestressing when pressed into a bore in the cantilever arms. The elastomer bushing is expediently locked via its shape and a this adapted contour of the hole.

Die aufgrund der Geometrie der Buchse gegebene Elastizität in Längsrichtung des Zuges ermöglicht die elastische Übertragung von Traktions- und Kupplungskräften. Wird eine bestimmbare Größenordnung, z.B. die für Stoßverzehrglieder annehmbare Endkraft von 150 kN erreicht, wird der elastische Längsweg durch Anschläge begrenzt, die zweckmäßigerweise durch zentrale Verlängerungen der Untergestelle, die zwischen den Kragarmen angeordnet sind, gebildet werden. Damit ist es möglich, Pufferkräfte nach UIC- oder AAR-Normen unter Umgehung der Gelenkkonstruktion zu übertragen.The elasticity in the longitudinal direction of the train due to the geometry of the bush enables the elastic transmission of traction and coupling forces. If a definable order of magnitude, e.g. the end force of 150 kN, which is acceptable for shock absorbing members, the elastic longitudinal path is limited by stops, which are expediently formed by central extensions of the underframes, which are arranged between the cantilever arms. This makes it possible to transfer buffer forces according to UIC or AAR standards, bypassing the joint construction.

Im Falle eines Auflaufstoßes, oder bei Unfällen sorgt die kalottenförmige Ausbildung der ineinandergreifenden Endanschläge für eine Zentrierung der Wagenkästen, die bei Überschreiten der das Gelenk stabilisierenden Querkräfte zwar zum Ausknicken, jedoch nicht zum Teleskopieren führen kann.In the event of an impact, or in the event of an accident, the dome-shaped design of the interlocking end stops ensures that the car bodies are centered, which, if the transverse forces stabilizing the joint are exceeded, can cause them to buckle, but not to telescope.

Die Drehgestelle, die als konventionelle, wiegenlose Luftfederdrehgestelle ausgeführt sein können, können direkt unter dem Querträger des Zwischenstücks angeordnet werden, wobei die Querwegbegrenzung über einen zentral angeordneten Notführungszapfen erfolgen kann und die Übertragung der Traktionskräfte zweckmäßigerweise über eine einseitig angeordnete Lenkerstange auf das Untergestell eines der benachbarten Wagenkästen erfolgt. Damit ist eine gleichmäßige Aufteilung der Traktionskräfte im Zugverband möglich, so daß über die Gelenke nur Differenzkräfte aus unterschiedlichen Adhäsionsverhältnissen übertragen werden müssen.The bogies, which can be designed as conventional, cradle-free air spring bogies, can be arranged directly under the cross member of the intermediate piece, whereby the transverse travel can be limited via a centrally located emergency guide pin and the transmission of the traction forces expediently via a one-sided handlebar to the underframe of one of the neighboring ones Car bodies are made. This makes it possible to distribute the traction forces evenly in the train structure, so that only differential forces from different adhesion conditions have to be transmitted via the joints.

Einbauhöhe und Anlenkung des Drehgestells am Zwischenstück können identisch mit den an den Endwagen direkt am Untergestell angeordneten Einbaudrehgestellen ausgeführt werden. Damit können Baugleichheit und Tauschbarkeit ebenso gewährleistet werden, wie die freizügige Anordnung von Antrieben.The installation height and articulation of the bogie on the intermediate piece can be identical to the built-on bogies on the end car, which are arranged directly on the base frame. This can be identical in construction and Interchangeability is guaranteed, as is the permissive arrangement of drives.

Wird das Zwischenstück als Zwischenstück mit entsprechend gewählter Einbaulänge ausgeführt, können ein Stromabnehmer und dessen Antrieb auf diesem und damit in der Drehgestellmitte angeordnet werden. Hierdurch wird eine Minimierung der aus der Wagenkastendynamik auf das Stromabnehmerschleifstück wirkenden lateralen Versatzbewegungen erreicht und ein größerer Spielraum für die Wahl eines bestimmten Wagenkasten-Neigungswinkels ermöglicht.If the intermediate piece is designed as an intermediate piece with an appropriately selected installation length, a pantograph and its drive can be arranged on it and thus in the center of the bogie. As a result, the lateral displacement movements acting on the pantograph slider from the car body dynamics are minimized and a greater scope for the selection of a specific car body inclination angle is made possible.

Im Folgenden wird die Erfindung anhand von Zeichnungen beispielhaft näher beschrieben. Es zeigen:

Das Schienenfahrzeug gemäß Fig. 1) besteht aus mehreren Wagenkästen 1, 2 auf Drehgestellen 3, 4, 5, wobei jeweils zwei Wagenkästen 1, 2 gemeinsam auf einem Drehgestell 4 gelagert sind. Zwischen den Wagenkästen sind Verbindungsstücke, hier Portale 6, 7 angeordnet. Über einem Wagenkasten 2 ist ein Stromabnehmer 8 angeordnet.The rail vehicle according to FIG. 1) consists of several car bodies 1, 2 on bogies 3, 4, 5, two car bodies 1, 2 each being mounted together on a bogie 4. Connections, here portals 6, 7, are arranged between the car bodies. A pantograph 8 is arranged above a car body 2.

Die Verbindung der Wagenkästen 11, 12 mittels eines Portals 16 ist der Fig. 2) zu entnehmen. Der Wagenkasten 11 ist mit dem Portal um eine Querachse Y schwenkbar verbunden. Hierzu ist er an seiner Unterseite mit zwei Kragarmen 111, 112 versehen, die sich in einem Abstand voneinander in Richtung auf die untere Querstrebe des Portals 16 erstrecken. Im zusammengefügten Zustand greifen die Kragarme 111, 112 in das Portal und sind dort mit elastischen Lagern in Lagerböcken 161, 162 gehalten. Die Querachse Y verläuft dann entlang der Lagerböcke 161, 162. Zwischen den Kragarmen 112, 113 ist in gleicher Richtung weisend und in der gleichen Ebene liegend eine Anschlagstange 113 angeordnet, deren kalottenförmiges Ende 114 im zuammengebauten Zustand über der Mitte der unteren Querstrebe des Portals 16 liegt. Der andere Wagenkasten 12 weist eine ähnliche Verbindung zum Portal 16 auf. Es sind ebenfalls zwei Kragarme 121, 122 vorgesehen, die so angeordnet sind, daß sie zwischen die Kragarme 111, 112 des ersten Wagenkastens 11 fassen können, wobei sie zwischen sich genug Platz für eine Anschlagstange 123 lassen, welche mit ihrem Ende in die kalottenförmige Ausnehmung 114 der Anschlagstange 113 am ersten Wagenkasten paßt. Im zusammengebauten Zustand liegen die beiden Anschlagstangen 113, 123 mit Spiel aneinander und verhindern ein Teleskopieren der beiden Wagenkästen bei Unfällen. Die Kragarme 121, 122 des zweiten Wagenkastens sind mit elastischen Lagerungen in Lagerböcken 166, 167 gehalten, die auf einem mittig auf der unteren Querstrebe des Portals 16 angeordneten Drehelement 165 angeordnet sind. Durch den Mittelpunkt dieses Drehelements 165 verläuft im zusammengebauten Zustand die Hochachse Z, um die der zweite Wagenkasten 12 schwenkbar in dem Protal gelagert ist. Bei Geradeausfahrt liegen die Querachsen der Lageraugen aller Kragarme 111, 112, 121, 122 entlang der unteren Querstrebe des Protals 16 in einer Hoch- und einer horizontalen Ebene. Der zweite Wagenkasten 12 ist über einen Lenker 125, der beidseitig kardanisch elastisch gelagert ist, mit der oberen Querstrebe des Portals 16 verbunden.The connection of the car bodies 11, 12 by means of a portal 16 can be seen in FIG. 2). The car body 11 is pivotally connected to the portal about a transverse axis Y. For this purpose, it is provided on its underside with two cantilever arms 111, 112, which are at a distance extend from each other in the direction of the lower cross strut of the portal 16. In the assembled state, the cantilever arms 111, 112 engage in the portal and are held there in bearing blocks 161, 162 with elastic bearings. The transverse axis Y then runs along the bearing blocks 161, 162. Between the cantilever arms 112, 113, a stop rod 113 is arranged pointing in the same direction and lying in the same plane, the dome-shaped end 114 of which, in the assembled state, lies above the center of the lower cross strut of the portal 16 lies. The other car body 12 has a similar connection to the portal 16. There are also two cantilever arms 121, 122 which are arranged so that they can grip between the cantilever arms 111, 112 of the first car body 11, leaving enough space between them for a stop rod 123, which ends in the dome-shaped recess 114 of the stop rod 113 fits on the first car body. In the assembled state, the two stop rods 113, 123 lie against one another with play and prevent the two car bodies from telescoping in the event of an accident. The cantilever arms 121, 122 of the second car body are held with elastic bearings in bearing blocks 166, 167, which are arranged on a rotating element 165 arranged centrally on the lower cross strut of the portal 16. In the assembled state, the vertical axis Z, through which the second car body 12 is pivotally mounted in the protal, runs through the center of this rotating element 165. When driving straight ahead, the transverse axes of the bearing eyes of all the cantilever arms 111, 112, 121, 122 lie along the lower cross strut of the protal 16 in a vertical and a horizontal plane. The second car body 12 is connected to the upper cross strut of the portal 16 via a link 125, which is gimbally elastically supported on both sides.

Fig. 3) und Fig. 4) zeigen ein elastisches Lagerelement 20 mit einem Elastomer 21, wobei in Fig. 4) das Lagerelement im nicht eingebauten Zustand und in Fig. 3) im eingesetzten Zustand dargestellt ist.3) and FIG. 4) show an elastic bearing element 20 with an elastomer 21, wherein in FIG. 4) the bearing element in the non-installed state and in FIG. 3) is shown in the inserted state.

Statt des in Fig. 2) gezeigten Lenkers ist es auch möglich, den zweiten Wagenkasten 32 über ein Gestänge mit dem Portal 36 zu verbinden, wie dies in Fig. 5) dargestellt ist. Das Gestänge besteht aus zwei, jeweils an beiden Enden elastisch kardanisch gelagerten Stangen 37, 38, von denen die eine mit der einen Seite an dem zweiten Wagenkasten 32 und mit der anderen Seite an einem Übersetzungsstück 39, das drehbar an den ersten Wagenkasten 31 befestigt ist, gelagert ist. Das Verbindungsstück 39 ist eine längliche Scheibe, die an ihrem unteren Ende die Verbindung zu dem ersten Wagenkasten 31 und an ihrem oberen Ende die Verbindung zu der Stange 37 aufweist. Zwischen diesen beiden Verbindungen liegt die Verbindung zu der zweiten Stange 38, die so mit ihrem einen Ende an dem Verbindungsstück 39 und mit ihrem anderen Ende an dem Portal 36 gelagert ist.Instead of the handlebar shown in FIG. 2), it is also possible to connect the second car body 32 to the portal 36 via a linkage, as is shown in FIG. 5). The linkage consists of two, at both ends, gimbal-mounted rods 37, 38, one of which has one side on the second body 32 and the other on a translation piece 39 which is rotatably attached to the first body 31 , is stored. The connecting piece 39 is an elongated disc which has the connection to the first car body 31 at its lower end and the connection to the rod 37 at its upper end. Between these two connections is the connection to the second rod 38, which is supported at one end on the connecting piece 39 and at the other end on the portal 36.
