Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Verbindungselement zur drehbaren Verbindung eines Wagenkastens mit einem Drehgestell eines Schienenfahrzeugs, wobei das Verbindungselement eine zum Wagenkasten ausrichtbare Begrenzungsfläche aufweist, auf welcher der Wagenkasten im montierten Zustand des Verbindungselements zumindest teilweise aufliegt.The invention relates to a connecting element for the rotatable connection of a car body to a bogie of a rail vehicle, the connecting element having a boundary surface which can be aligned with the car body and on which the car body at least partially rests when the connecting element is in the assembled state.

Ein solches Verbindungselement kann als Tauch- oder Drehzapfen ausgebildet sein zur Montage an einem Wagenkasten zwecks Längs- und Querkraftübertragung zwischen einem Drehgestell und dem Wagenkasten, wobei der Tauch- oder Drehzapfen sich entlang seiner Längsachse von einem breiten Ende zu einem schmalen Ende verjüngt.Such a connecting element can be designed as a plunger or pivot for mounting on a car body for the purpose of transmitting longitudinal and transverse force between a bogie and the car body, the plunger or pivot tapering along its longitudinal axis from a wide end to a narrow end.

Der Tauch- oder Drehzapfen verjüngt sich in Richtung seiner Längsachse, welche im montierten Zustand des Tauch- oder Drehzapfen die Drehachse bildet, sodass das schmale Ende des Tauch- oder Drehzapfens den eigentlichen Zapfen bildet.The plunger or trunnion tapers in the direction of its longitudinal axis, which forms the rotational axis when the plunger or trunnion is assembled, so that the narrow end of the plunger or trunnion forms the actual spigot.

Dabei wird in der Regel das breite Ende des Tauch- oder Drehzapfens am Wagenkasten befestigt und das schmale Ende des Tauch- oder Drehzapfens ragt in eine Öffnung an einem Drehgestell. In dem Sinne, dass die Längsachse die Drehachse ist, ist es auch denkbar, dass die Abmessung des Tauch- oder Drehzapfens in Richtung der Längsachse kleiner ist als normal dazu, dass der Tauch- oder Drehzapfen also weniger lang als breit ist.The wide end of the plunger or pivot is usually attached to the car body and the narrow end of the plunger or pivot protrudes into an opening on a bogie. In the sense that the longitudinal axis is the axis of rotation, it is also conceivable that the dimension of the plunger or pivot in the direction of the longitudinal axis is smaller than normal, so that the plunger or pivot is therefore less long than wide.

Der Tauch- oder Drehzapfen überträgt üblicher Weise Längskräfte, Querkräfte und Vertikalkräfte.The plunger or trunnion usually transmits longitudinal forces, lateral forces and vertical forces.

Tauchzapfen drehen sich selbst, haben aber, im Unterschied zu Drehzapfen, keine runde Buchse oder Ähnliches, wie es bei einer Lemniskatenanlenkung von Drehzapfen der Fall ist.Plungers turn themselves, but, unlike pivots, do not have a round bushing or the like, as is the case with a lemniscate articulation of pivots.

Das Verbindungselement kann - statt eines Tauch-oder Drehzapfens oder zusätzlich zu einem Tauch-oder Drehzapfen - aber auch eine Wiege oder Traverse umfassen, also Bauteile, die in der Regel quer zur Längsachse des Wagenkastens (quer zur Fahrtrichtung) angeordnet sind.Instead of a plunger or pivot or in addition to a plunger or pivot, the connecting element can also comprise a cradle or traverse, that is to say components which are generally arranged transversely to the longitudinal axis of the car body (transversely to the direction of travel).

Eine Wiege dient zur Verbesserung der Laufeigenschaften von Drehgestellen. Dabei nimmt ein an seinen Enden beweglich und durch die Sekundärfedern abgefedert mit dem Drehgestellrahmen verbundener Querträger die Wagenkastenkräfte auf. Typischerweise ruht der Wagenkasten dabei außen auf Gleitplatten, sodass Drehzapfen und -pfanne nur noch die Längskräfte übertragen und kein Gewicht mehr zu tragen haben.A cradle is used to improve the running properties of bogies. In this case, a cross member, which is movable at its ends and connected to the bogie frame by the secondary springs, absorbs the bodywork forces. Typically, the car body rests on the outside on sliding plates, so that the pivot pin and socket only transmit the longitudinal forces and no longer have to carry any weight.

Eine Traverse oder Neigetraverse ist eine tragende Struktur aus geschweißten, geschmiedeten oder gefrästen Bauteilen aus Stahl oder einer Aluminiumlegierung. Bei einer Neigetraverse sind zusätzlich Komponenten für die aktive (mit Aktuatorik) oder passive Neigefunktion integriert. Zur Fahrstabilisierung im oberen Geschwindigkeitsbereich kann zwischen Drehgestellrahmen und Neigetraverse je ein Schlingerdämpfer angebracht werden.A traverse or tilt traverse is a supporting structure made of welded, forged or milled components made of steel or an aluminum alloy. Additional components for the active (with actuator system) or passive tilt function are integrated in a tilt traverse. A roll damper can be attached between the bogie frame and the tilting crossbar to stabilize driving in the upper speed range.

Neuer Stand der TechnikState of the art

Tauchzapfen oder Drehzapfen sind an der Unterseite des Wagenkastens lösbar befestigt, etwa durch Verschrauben mit dem Wagenkasten. Um auch Längsstöße, etwa bei einem Unfall, aufnehmen zu können, werden die Tauch- oder Drehzapfen üblicher Weise aus einem duktilen Werkstoff, wie Stahl, hergestellt.Dip pins or pivot pins are detachably attached to the underside of the car body, for example by screwing them to the car body. In order to be able to absorb longitudinal impacts, for example in the event of an accident, the plungers or pivot pins are Usually made from a ductile material such as steel.

Längs eines Wagenkastens, insbesondere eines Schienenfahrzeugs, müssen auch Kabelstränge untergebracht werden. Die Verlegung von Kabelsträngen entlang eines Wagenkastens verursacht besonders im Bereich der Verbindung des Wagenkastens mit dem Drehgestell konstruktive Probleme, da dort Bauraum nur sehr eingeschränkt zur Verfügung steht.Cable harnesses must also be accommodated along a car body, in particular a rail vehicle. The laying of cable strands along a car body causes structural problems, particularly in the area of the connection of the car body to the bogie, since there is only very limited space available.

Kabelstränge von Schienenfahrzeugen werden üblicher Weise entlang des Unterbaus von Wagenkästen in Kabelkanälen oder - schächten geführt. Im Bereich der Koppel- oder Verbindungselemente (Tauchzapfen, Drehzapfen, Wiegen, Traversen) können die Kabelkanäle oder -schächte bzw. die Kabel oberhalb des Verbindungselements geführt werden, z. B. schwenkt der Kabelkanal in diesem Bereich nach oben in den Unterbau des Wagenkastens hinein. Oder der Kabelkanal wird im Bereich des Verbindungselements seitlich um das Verbindungselement geführt, also seitlich verschwenkt geführt.Cable runs of rail vehicles are usually routed along the substructure of car bodies in cable ducts or shafts. In the area of the coupling or connecting elements (immersion pins, pivot pins, weighing, traverses), the cable channels or shafts or the cables can be routed above the connecting element, e.g. B. the cable duct swings up in this area into the substructure of the car body. Or the cable duct is guided laterally around the connecting element in the region of the connecting element, that is to say it is pivoted laterally.

In der WO 2014/076788 A1 ist ein Schienenfahrzeug mit einem Wagenkasten und einem Fahrwerk, der einen Fahrwerksrahmen aufweist, offenbart. Zwischen dem Wagenkasten und dem Fahrwerksrahmen ist ein Drehzapfen zur Kraftübertragung zwischen dem Wagenkasten und dem Fahrwerk angeordnet. Der Drehzapfen weist eine Ausnehmung auf, deren Längsachse mit einer Drehzapfen-Längsachse fluchtet.In the WO 2014/076788 A1 discloses a rail vehicle with a body and a chassis having a chassis frame. Between the car body and the undercarriage frame there is a pivot for power transmission between the car body and the undercarriage. The pivot has a recess, the longitudinal axis of which is aligned with a longitudinal axis of the pivot.

Die DE 10 2010 011 568 A1 zeigt eine Lösung, wo die Bodenstruktur eines Schienenfahrzeugs Gerippe und flächige Strukturteile aufweist und Kabel zwischen dem Gerippe und den flächigen Strukturteilen angeordnet sind. Vom Gerippe der Bodenstruktur geht ein nach unten gerichteter Drehzapfen aus. Gemäß Fig. 3 der DE 10 2010 011 568 A1 werden die Kabel also - unter anderem - oberhalb des Verbindungselements, hier ein Drehzapfen, durch den Wagenkasten geführt.
Wenn die Kabel aber oberhalb des Verbindungselements geführt werden, müssen dabei oft tragende Strukturen des Wagenkastens durchbrochen werden.The DE 10 2010 011 568 A1 shows a solution where the floor structure of a rail vehicle has skeletons and flat structural parts and cables are arranged between the skeleton and the flat structural parts. A pivot pointing downwards extends from the skeleton of the floor structure. 3 of the DE 10 2010 011 568 A1 so the cables - Among other things - above the connecting element, here a pivot, guided through the car body.
However, if the cables are routed above the connecting element, it is often necessary to break through the supporting structures of the car body.

Darstellung der ErfindungPresentation of the invention

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verbindungselement zur Verfügung zu stellen, welches eine Führung von Kabeln ohne Durchbrechung von tragenden Strukturen des Wagenkastens und gegebenenfalls ohne Verlängerung der Kabelwege durch seitliche Umgehung eines Tauch- oder Drehzapfens ermöglicht.It is therefore an object of the present invention to provide a connecting element which enables cables to be guided without breaking through the supporting structures of the car body and, if appropriate, without lengthening the cable paths by bypassing a plunger or pivot pin at the side.

Diese Aufgabe wird durch ein Verbindungselement mit den Merkmalen des Patentanspruchs 1 gelöst, wobei das Verbindungselement eine zum Wagenkasten ausrichtbare Begrenzungsfläche aufweist, auf welcher der Wagenkasten im montierten Zustand des Verbindungselements zumindest teilweise aufliegt. Diese Begrenzungsfläche kann, muss aber nicht eben sein.This object is achieved by a connecting element having the features of patent claim 1, the connecting element having a delimiting surface that can be aligned with the car body, on which the car body at least partially rests in the assembled state of the connecting element. This boundary surface can, but does not have to be flat.

Dabei ist erfindungsgemäß vorgesehen, dass das Verbindungselement in der - zum Wagenkasten ausrichtbaren - Begrenzungsfläche zumindest eine rinnenförmige Ausnehmung aufweist, welche die gesamte Begrenzungsfläche durchzieht.It is provided according to the invention that the connecting element has at least one trough-shaped recess in the boundary surface which can be aligned with the car body and which extends through the entire boundary surface.

Gemäß der Erfindung bildet die durchgängige rinnenförmige Ausnehmung im montierten Zustand einen Tunnel durch das Verbindungselement hindurch und es können durch die rinnenförmige Ausnehmung im Verbindungselement Kabel oder andere Leitungen geführt werden, sodass in der tragenden Struktur des Wagenkastens keine Durchbrüche vorgesehen werden müssen. Kabel, die längs des Wagenkastens an dessen Unterseite verlaufen, können bei montiertem Verbindungselement längs der Ausnehmung, z.B. in gerader Linie, durch die Ausnehmung geführt werden, also auch dort an der Unterseite des Wagenkastens verlaufen.According to the invention, the continuous trough-shaped recess in the assembled state forms a tunnel through the connecting element, and cables or other lines can be guided through the trough-shaped recess in the connecting element, so that no openings have to be provided in the load-bearing structure of the car body. Cables that run along the underside of the car body can Connecting element along the recess, for example in a straight line, are passed through the recess, that is to say also run there on the underside of the car body.

Dadurch, dass die Ausnehmung durch ihre Rinnenform offen ist, kann das Verbindungselement grundsätzlich auch ohne Demontage der Kabel oder Leitungen am Wagenkasten montiert und demontiert werden.Because the recess is open due to its channel shape, the connecting element can in principle also be assembled and disassembled on the car body without dismantling the cables or lines.

Die Ausnehmung kann gerade sein, was kurze Kabel- oder andere Leitungslängen bedingt. Es wäre aber auch denkbar, dass die Ausnehmung einen gekrümmten Verlauf nimmt, etwa, um eine Leitung innerhalb des Verbindungselements um einen Winkel umzulenken (z.B. aus der Richtung längs des Wagenkastens in eine Richtung quer zur Längsrichtung des Wagenkastens).The recess can be straight, which requires short cable or other line lengths. However, it would also be conceivable for the recess to take a curved course, for example in order to deflect a line within the connecting element by an angle (e.g. from the direction along the car body in a direction transverse to the longitudinal direction of the car body).

Es kann genau eine Ausnehmung vorgesehen sein, insbesondere dann, wenn diese so groß ist, dass alle Kabeln oder Leitungen aufgenommen werden können und diese den gleichen Verlauf haben. Selbstverständlich können auch mehrere Ausnehmungen vorgesehen werden, die entweder parallel zueinander verlaufen oder zueinander unterschiedliche Verläufe aufweisen können.Exactly one recess can be provided, in particular if it is so large that all cables or lines can be received and these have the same course. Of course, several recesses can also be provided, which either run parallel to one another or can have different courses to one another.

Die Ausnehmung kann so ausgebildet werden, dass diese im montierten Zustand des Verbindungselements in Längsrichtung des Wagenkastens ausrichtbar ist. Es ist jedoch auch denkbar, dass die Ausnehmung im montierten Zustand des Verbindungselements z.B. quer zum Wagenkasten verläuft, um quer verlaufende Leitungen durch das Verbindungselement zu führen.The recess can be designed such that it can be aligned in the longitudinal direction of the car body in the assembled state of the connecting element. However, it is also conceivable that the recess in the assembled state of the connecting element e.g. extends transversely to the car body in order to lead transverse cables through the connecting element.

In der Regel wird die rinnenförmige Ausnehmung
über ihre Länge die gleiche Höhe aufweisen, es wäre aber auch denkbar, dass sich die Höhe ändert, die Ausnehmung sich also etwa an einer Seite tiefer in das Verbindungselement "eingräbt" als auf einer anderen Seite des Verbindungselements. In der Regel wird die Ausnehmung bei einem Tauch- oder Drehzapfen normal zu seiner Längsachse verlaufen.As a rule, the trough-shaped recess
have the same height over their length, but it would also be conceivable that the height changes, that is to say the recess "digs" deeper into the connecting element on one side than on another side of the connecting element. Usually the recess is at a plunger or trunnion is normal to its longitudinal axis.

Um dem Verbindungselement, insbesondere dem Tauch- oder Drehzapfen, trotz der Ausnehmung größtmögliche Stabilität zu verleihen, kann vorgesehen sein, dass die Ausnehmung gewölbt ist, beim Tauch- oder Drehzapfen also etwa zum schmalen Ende des Tauch- oder Drehzapfens hin gewölbt ist. Eine Wölbung im Sinne einer stetigen Kurve weist, ähnlich der Begrenzungsfläche eines Tunnels, keine Ecken auf, sodass etwaige Spannungen im Verbindungselement gleichmäßig um die Ausnehmung verteilt werden. Sonst könnte für die Ausnehmung auch ein rechteckiger Querschnitt verwendet werden, wie er für Kabelkanäle oder -schächte sonst üblich ist.In order to give the connecting element, in particular the plunger or trunnion, the greatest possible stability despite the recess, it can be provided that the recess is curved, that is to say when the plunger or pivot is curved toward the narrow end of the plunger or pivot. A curvature in the sense of a continuous curve, similar to the boundary surface of a tunnel, has no corners, so that any stresses in the connecting element are evenly distributed around the recess. Otherwise, a rectangular cross-section could also be used for the recess, as is otherwise customary for cable ducts or shafts.

Insbesondere wenn nur eine Ausnehmung im Verbindungselement vorgesehen ist, können die Teile des Verbindungselements, welche die Ausnehmung umgeben, eine offene Dreieckstruktur bilden, wobei die beiden Schenkel des Dreiecks an ihren Enden am Wagenkasten befestigt werden und dadurch dem Verbindungselement seine Stabilität verleihen. So kann der - im montierten Zustand - nach oben geöffnete Tauch- oder Drehzapfen die Form eines "Y" bilden, wobei der obere Teil des "Y" die beiden Schenkel des Dreiecks und in seinem Inneren die Ausnehmung bildet. Der untere Teil des "Y" bildet den eigentlichen Zapfen, der in das Drehgestell eingreift. Erst wenn die beiden Schenkel des "Y" (bzw. im allgemeinen Fall des Dreiecks) an ihren freien Enden mit dem Wagenkasten verbunden werden, ergibt sich eine stabile geschlossene Dreiecksstruktur.In particular if only one recess is provided in the connecting element, the parts of the connecting element which surround the recess can form an open triangular structure, the two legs of the triangle being fastened at their ends to the car body and thereby giving the connecting element its stability. Thus, in the assembled state, the plunger or trunnion which is open at the top can form the shape of a "Y", the upper part of the "Y" forming the two legs of the triangle and the recess in its interior. The lower part of the "Y" forms the actual pin which engages in the bogie. Only when the two legs of the "Y" (or in the general case of the triangle) are connected to the car body at their free ends, does a stable closed triangular structure result.

Das Verbindungselement kann als Tauch- oder Drehzapfen zwecks Längs- und Querkraftübertragung zwischen dem Drehgestell und dem Wagenkasten ausgebildet sein, wobei der Tauch- oder Drehzapfen sich entlang seiner Längsachse von einem breiten Ende zu einem schmalen Ende verjüngt, wobei die rinnenförmige Ausnehmung zum breiten Ende hin offen ist.The connecting element can be designed as a plunger or trunnion for the purpose of longitudinal and transverse force transmission between the bogie and the car body, the plunger or trunnion tapering along its longitudinal axis from a wide end to a narrow end, the groove-shaped recess toward the broad end is open.

In einer Ausführungsform weist der Tauch- oder Drehzapfen genau eine Ausnehmung auf, die durch die Längsachse des Tauch- oder Drehzapfens verläuft. Dadurch können im montierten Zustand des Tauch- oder Drehzapfens Kabel bzw. Kabelkanäle, die mittig am und längs des Wagenkastens angeordnet sind, gerade durch den Tauch- oder Drehzapfen geführt werden.In one embodiment, the immersion or pivot pin has exactly one recess, which runs through the longitudinal axis of the immersion or pivot pin. As a result, in the assembled state of the plunger or trunnion, cables or cable ducts which are arranged centrally on and along the car body can be guided straight through the plunger or trunnion.

Die Ausnehmung kann am breiten Ende des Tauch- oder Drehzapfens eine Breite von 10-90%, insbesondere von einer Hälfte bis zu einem Drittel, der Breite des breiten Endes, gemessen in der gleichen Richtung wie die Breite der Ausnehmung, aufweisen. Dies stellt eine ausreichende Stabilität des Tauch- oder Drehzapfens sicher.The recess can have a width of 10-90%, in particular from one half to one third, of the width of the wide end, measured in the same direction as the width of the recess, at the wide end of the plunger or pivot. This ensures sufficient stability of the plunger or pivot.

Wenn die Breite der Ausnehmung am breiten Ende des Tauch-oder Drehzapfens die maximale Breite der Ausnehmung ist und sich die Breite der Ausnehmung zum schmalen Ende des Tauch-oder Drehzapfens hin nicht erhöht (sondern nur gleichbleibt und sich nicht verringert), dann ist sichergestellt, dass der Tauch- oder Drehzapfen vom Wagenkasten abgenommen werden kann, ohne die in der Ausnehmung befindlichen Einbauten (Kabel, Kabelkanäle oder -schächte) ebenfalls demontieren zu müssen.If the width of the recess at the wide end of the plunger or pivot is the maximum width of the recess and the width of the recess does not increase towards the narrow end of the plunger or pivot (but only remains the same and does not decrease), then it is ensured that that the immersion or pivot pin can be removed from the car body without having to dismantle the internals located in the recess (cables, cable ducts or shafts).

Die Ausnehmung kann je nach dem Platz, der für Leitungen benötigt wird, und je nach der erforderlichen Stabilität des Verbindungselements eine Höhe von 10-90% der Höhe des Verbindungselements aufweisen. Die Höhe des Verbindungselements kann im Bereich von 0,5 bis 2,5 m liegen. Grundsätzlich wäre es denkbar, auch eine sehr geringe Höhe von einigen mm zuzulassen, die für ein dünnes Kabel ausreichend wäre. In der Regel wird man aber, unabhängig von der absoluten Höhe des Verbindungselements, eine Höhe von zumindest einem Zentimeter vorsehen, wobei auch geringe Höhen von 2-5 cm denkbar wären.Depending on the space required for lines and the required stability of the connecting element, the recess can have a height of 10-90% of the height of the connecting element. The height of the connecting element can range from 0.5 to 2.5 m. In principle, it would be conceivable to allow a very small height of a few mm, which would be sufficient for a thin cable. As a rule, however, regardless of the absolute height of the connecting element, a height of at least one centimeter will be provided, although small heights of 2-5 cm would also be conceivable.

Die Erfindung umfasst auch einen Wagenkasten mit einem daran montierten erfindungsgemäßen Verbindungselement, wobei der Wagenkasten zumindest teilweise auf der Begrenzungsfläche aufliegt, welche die rinnenförmige Ausnehmung aufweist. Durch diese Ausnehmung verlaufen dann zumindest ein Kabelkanal und/oder zumindest ein Kabel oder eine andere Leitung, wie eine Druckluftleitung.The invention also includes a car body with a connecting element according to the invention mounted thereon, the car body resting at least partially on the boundary surface which has the channel-shaped recess. At least one cable duct and / or at least one cable or another line, such as a compressed air line, then runs through this recess.

Durch das erfindungsgemäße Verbindungselement, etwa einen erfindungsgemäßen Tauch- oder Drehzapfen, wird der Bauraum im Unterflurbereich um das Verbindungselement nicht durch Kabelstränge beansprucht. Die Fußbodenhöhe des Wagenkastens wird niedrig gehalten, weil keine Höhe für etwaige Durchbrüche für Kabelstränge vorgesehen werden muss. Schließlich können aufgrund der geraden Verlegung von Kabeln durch das Verbindungselement Kabellängen reduziert werden gegenüber einer Kabelführung seitlich oder oben um das Verbindungselement herum.As a result of the connecting element according to the invention, for example an immersion or pivot pin according to the invention, the installation space in the underfloor area around the connecting element is not occupied by cable harnesses. The floor height of the car body is kept low because no height has to be provided for any openings for cable harnesses. Finally, due to the straight laying of cables through the connecting element, cable lengths can be reduced compared to a cable guide to the side or above around the connecting element.

Kurzbeschreibung der FigurenBrief description of the figures

Zur weiteren Erläuterung der Erfindung wird im nachfolgenden Teil der Beschreibung auf die Figuren Bezug genommen, aus der weitere vorteilhafte Ausgestaltungen, Einzelheiten und Weiterbildungen der Erfindung zu entnehmen sind. Es zeigen:

  • Fig. 1 einen an einem Schienenfahrzeug befestigten erfindungsgemäßen Tauchzapfen in Seitenansicht (in Längsrichtung des Schienenfahrzeugs gesehen),
  • Fig. 2 den Tauchzapfen aus Fig. 1 in einer anderen Seitenansicht (in Querrichtung des Schienenfahrzeugs gesehen).
To further explain the invention, reference is made to the figures in the following part of the description, from which further advantageous refinements, details and developments of the invention can be found. Show it:
  • Fig. 1 a dip pin according to the invention fastened to a rail vehicle in side view (seen in the longitudinal direction of the rail vehicle),
  • Fig. 2 the plunger Fig. 1 in a different side view (seen in the transverse direction of the rail vehicle).

Ausführung der ErfindungImplementation of the invention

Fig. 1 zeigt einen erfindungsgemäßen Tauchzapfen 1 derart, dass oben das breite Ende 2 und unten das schmale Ende 3 des Tauchzapfens zu liegen kommt. Der Tauchzapfen 1 hat in etwa die Form eines vierseitigen Pyramidenstumpfs, der zum schmalen Ende 3 hin in einen Quader übergeht. Die Abmessung (die Höhe) des Tauchzapfens 1 beträgt in der dargestellten Form in Richtung der Längsachse 4, in Abhängigkeit von der Art des Schienenfahrzeugs, 0,5 bis 2,5 Meter. Da die Längsachse 4 des Tauchzapfens 1 im Betriebszustand des Tauchzapfens 1 seine Drehachse ist, ist es auch denkbar, dass die Abmessung des Tauchzapfens 1 in Richtung der Längsachse 4 kleiner ist als normal dazu, dass der Tauchzapfen also weniger lang als breit ist. Dies ist hier nicht der Fall. Fig. 1 shows a plunger 1 according to the invention such that the wide end 2 and the narrow end 3 of the plunger comes to rest at the top. The plunger 1 has approximately the shape of a four-sided truncated pyramid which merges into a cuboid toward the narrow end 3. The dimension (the height) of the plunger 1 is in the form shown in the direction of the longitudinal axis 4, depending on the type of rail vehicle, 0.5 to 2.5 meters. Since the longitudinal axis 4 of the plunger 1 is its axis of rotation when the plunger 1 is in the operating state, it is also conceivable that the dimension of the plunger 1 in the direction of the longitudinal axis 4 is smaller than normal so that the plunger is therefore less long than wide. This is not the case here.

Am breiten Ende 2 des Tauchzapfens 1 ist an zwei gegenüberliegenden Seiten des Grundkörpers jeweils ein Verschraubungsabschnitt 5 vorgesehen, mit welchem der Tauchzapfen 1 mit dem Boden des Wagenkastens 9 verschraubt ist. Das schmale Ende 3 ragt dann nach unten in ein - hier nicht dargestelltes - Drehgestell. So bildet der nach oben geöffnete Tauchzapfen 1 die Form eines "Y", wobei der obere Teil des "Y" die beiden Schenkel eines Dreiecks und in seinem Inneren die Ausnehmung 6 bildet. Der untere Teil des "Y" bildet den eigentlichen Zapfen, der in das Drehgestell eingreift. Erst wenn die beiden Schenkel des "Y" an ihren freien Enden mittels Verschraubungsabschnitten 5 mit dem Wagenkasten 9 verbunden werden, ergibt sich eine stabile geschlossene Dreiecksstruktur.At the wide end 2 of the plunger 1, a screw section 5 is provided on two opposite sides of the base body, with which the plunger 1 is screwed to the bottom of the car body 9. The narrow end 3 then projects downward into a bogie - not shown here. Thus, the upwardly open plunger 1 forms the shape of a "Y", the upper part of the "Y" forming the two legs of a triangle and the recess 6 in its interior. The lower part of the "Y" forms the actual pin which engages in the bogie. Only when the two legs of the "Y" are connected to the car body 9 at their free ends by means of screw sections 5, does a stable, closed triangular structure result.

Am breiten Ende 2 des Tauchzapfens 1 ist eine gerade, in etwa halbkreisförmige Ausnehmung 6 durch den Tauchzapfen 1 vorgesehen, wobei die Längsachse der Ausnehmung 6 normal zur Längsachse (Drehachse) 4 des Tauchzapfens 1 verläuft und diese schneidet. Die Ausnehmung 6 wölbt sich weg von der sonst ebenen Auflagefläche, mit welcher das breite Ende 2 des Tauchzapfens 1 am Wagenkasten 9 aufliegt und welche die hier ebene Begrenzungsfläche 11 des Tauchzapfens 1 bildet. Der Tauchzapfen 1 ist bezüglich des Wagenkastens 9 so ausgerichtet, dass die Längsachse der Ausnehmung 6 (hier normal zur Zeichenebene verlaufend) parallel zur Längsrichtung des Wagenkastens 9 verläuft. Es wäre auch denkbar, dass statt der eingezeichneten Ausnehmung 6 oder zusätzlich zu dieser eine weitere Ausnehmung quer zum Wagenkasten 9 verläuft.At the wide end 2 of the plunger 1, a straight, approximately semicircular recess 6 is provided through the plunger 1, the longitudinal axis of the recess 6 running normal to the longitudinal axis (axis of rotation) 4 of the plunger 1 and cutting it. The recess 6 bulges away from the otherwise flat contact surface with which the wide end 2 of the The immersion pin 1 rests on the car body 9 and which forms the flat boundary surface 11 of the immersion pin 1 here. The plunger pin 1 is aligned with respect to the car body 9 such that the longitudinal axis of the recess 6 (here normal to the plane of the drawing) runs parallel to the longitudinal direction of the car body 9. It would also be conceivable that instead of the drawn-in recess 6 or in addition to this, a further recess runs transversely to the car body 9.

Die Ausnehmung 6 hat (in Fig. 1 von links nach rechts gemessen) eine Breite, die etwas weniger als die Hälfte des breiten Endes 2 (gemessen in der selben Richtung) beträgt und gleichzeitig die größte Breite der Ausnehmung 6 ist, wobei die Breite der Ausnehmung 6 immer normal zur Längsachse 4 gemessen wird. Durch die Wölbung der Ausnehmung 6 verjüngt sich diese stetig längs der Längsachse 4 in Richtung des schmalen Endes 3. Die größte Höhe der Ausnehmung 6 (gemessen in Richtung der Längsachse 4) ist etwas kleiner als deren größte Breite.The recess 6 has (in Fig. 1 measured from left to right) a width that is slightly less than half of the wide end 2 (measured in the same direction) and at the same time is the greatest width of the recess 6, the width of the recess 6 always being measured normal to the longitudinal axis 4 . Due to the curvature of the recess 6, the recess tapers continuously along the longitudinal axis 4 in the direction of the narrow end 3. The greatest height of the recess 6 (measured in the direction of the longitudinal axis 4) is somewhat smaller than its greatest width.

Durch die Ausnehmung 6 ist ein nach oben offener oder geschlossener Kabelkanal 7 mit etwa quadratischem Querschnitt geführt, in welchem mehrere Kabel 8 verlegt sind.An upwardly open or closed cable duct 7 with an approximately square cross section is guided through the recess 6, in which a plurality of cables 8 are laid.

In Fig. 2 ist erkennbar, dass der Kabelkanal 7 gerade längs des Wagenkastens 9 an dessen Unterseite und durch die Ausnehmung 6 verläuft.In Fig. 2 it can be seen that the cable duct 7 runs straight along the car body 9 on its underside and through the recess 6.

Der Tauchzapfen 1 kann auf verschiedene Art hergestellt werden. Er kann als Gussteil aus einer Stahl- oder Aluminiumlegierung hergestellt werden, z.B. auch aus Grauguss. Er kann aber auch aus Stahl oder Aluminium geschweißt, geschmiedet, gefräst (insbesondere aus dem Vollen gefräst) werden. Er kann neben der Ausnehmung oder den Ausnehmungen 6 auch Hohlräume aufweisen, was Gewicht einspart.The plunger 1 can be manufactured in various ways. It can be made as a cast part from a steel or aluminum alloy, for example also from gray cast iron. However, it can also be welded, forged, milled from steel or aluminum (in particular milled from solid). In addition to the recess or recesses 6, it can also have cavities, which saves weight.

Der Tauchzapfen 1 ist an seinem breiten Ende 2 in Querrichtung des Wagenkastens 9 (von links nach rechts in Fig. 1 gemessen) etwa 0,5 - 2 m breit, in Längsrichtung des Wagenkastens 9 gemessen (von links nach rechts in Fig. 2) etwa 0,3 - 0,8 m breit. Das schmale Ende 3 ist in Querrichtung (von links nach rechts in Fig. 1 gemessen) etwa 0,2 - 0,7 m breit, in Längsrichtung gemessen (von links nach rechts in Fig. 2) etwa 0,5 - 1 m breit. Die größte Breite der Ausnehmung 6 beträgt 0,2 - 0,5 m, die größte Höhe der Ausnehmung 6 beträgt 0,1 - 0,3 m.The plunger 1 is at its wide end 2 in the transverse direction of the body 9 (from left to right in Fig. 1 measured) about 0.5 - 2 m wide, measured in the longitudinal direction of the body 9 (from left to right in Fig. 2 ) about 0.3 - 0.8 m wide. The narrow end 3 is in the transverse direction (from left to right in Fig. 1 measured) about 0.2 - 0.7 m wide, measured lengthways (from left to right in Fig. 2 ) about 0.5 - 1 m wide. The greatest width of the recess 6 is 0.2-0.5 m, the greatest height of the recess 6 is 0.1-0.3 m.
