Abstract

Vehicle (101) comprises a longitudinal axis (101.1) whereby pitch joint is embodied as a rod assembly which extends substantially on one pitch joint level and encompasses two pitch joint arms (104.1, 104.2), two pitch joint rods (104.3, 104.4), and a coupling device (104.5). The pitch joint arms are pivotally hinged to first superstructure in region of first end. One of the pitch joint arms is pivotally hinged to the free second end of one of the pitch joint arms in the region of the first end. The pitch joint rods are pivotally hinged to the second superstructure in the region of the second end, and the coupling device couples the two pitch joint arms to each other such that the two pitch joint arms perform swiveling movements in opposite directions about the hinged points on the first superstructure.

Description

Die vorliegende Erfindung betrifft ein Fahrzeug, insbesondere ein Schienenfahrzeug, mit einer Fahrzeuglängsachse, einem ersten Wagenkasten, einem zweiten Wagenkasten, der dem ersten Wagenkasten in Richtung der Fahrzeuglängsachse benachbart ist, und einem Nickgelenk, welches den ersten Wagenkasten und den zweiten Wagenkasten verbindet. Sie betrifft weiterhin ein entsprechendes Nickgelenk für ein erfindungsgemäßes Fahrzeug.The present invention relates to a vehicle, in particular a rail vehicle, with a vehicle longitudinal axis, a first car body, a second car body, which is adjacent to the first car body in the direction of the vehicle longitudinal axis, and a pitch joint, which connects the first car body and the second car body. It further relates to a corresponding pitch joint for a vehicle according to the invention.

Bei Schienenfahrzeugen - aber auch bei anderen Fahrzeugen - werden Nickgelenke eingesetzt, wenn Wagenteile, beispielsweise Wagenkästen, mittels schwebender Gelenke bei einem mehrgliedrigen Gelenkzug verbunden werden und bei Befahrung von Kuppen oder Wannen an dieser Gelenkverbindung eine Nickmöglichkeit, also eine Schwenkmöglichkeit um eine in der Regel im Wesentlichen horizontal verlaufender Fahrzeugquerachse, erforderlich ist.In rail vehicles - but also in other vehicles - pitch joints are used when car parts, such as car bodies, are connected by floating joints in a multi-link articulated train and when driving on hills or troughs at this joint connection a pitch option, so a swivel possibility to a usually in Essentially horizontal transverse vehicle transverse axis, is required.

Im Fahrwerksbereich sind die Wagenteile in der Regel durch ein unteres Gelenk verbunden. Dieses untere Gelenk gestattet üblicherweise in bestimmten Grenzen folgende Relativbewegungen der Wagenteile: die Rotation um eine Fahrzeughochachse (Z-Achse), das so genannte Schwenken, und die Rotation um eine Fahrzeugquerachse (Y-Achse), das so genannte Nicken. Je nach Art dieses untere Gelenks kann gegebenenfalls auch eine Rotation um die Fahrzeuglängsachse (X-Achse ), das so genannte Wanken zugelassen sein.In the chassis area, the car parts are usually connected by a lower joint. This lower joint usually allows within certain limits the following relative movements of the car parts: the rotation about a vehicle's vertical axis (Z-axis), the so-called pivoting, and the rotation about a vehicle transverse axis (Y-axis), the so-called nodding. Depending on the nature of this lower joint may optionally also be a rotation about the vehicle longitudinal axis (X-axis), the so-called rolling allowed.

Bei Einfahrt in Kurven kommt es zu unterschiedlichen Wankstellungen der einzelnen Wagenteile innerhalb eines mehrgliedrigen Fahrzeuges. Diese bewirken abhängig von der Bauart des unteren Gelenks einen großen Querversatz zwischen den einzelnen Wagenteilen bzw. eine hohe Torsionsbeanspruchung der unteren Lager. Aus diesem Grund werden die Wagenteile im Bereich der Dachkonstruktion durch eine zusätzliche Queranbindung, die unter anderem auch als Wankstütze bezeichnet wird, gegeneinander abgestützt. Hierbei handelt es sich üblicherweise um einen sich unter anderem in Fahrzeugquerrichtung erstreckenden, an beiden Wagenteilen angelenkten Querlenker oder eine Kulissenführung.When entering curves it comes to different roll positions of the individual car parts within a multi-unit vehicle. These cause, depending on the design of the lower joint, a large transverse offset between the individual carriage parts or a high torsional stress on the lower bearings. For this reason, the car parts in the roof construction by an additional cross-connection, which is also known as anti-roll support, supported against each other. This is usually a transverse link, which extends, inter alia, in the vehicle transverse direction and is articulated on both carriage parts, or a link guide.

Diese Lösungen haben jedoch eine Reihe von Nachteilen. So nähert sich bei Kurvenfahrt bei der üblichen jeweils außermittigen Lagerung des Querlenkers das kurveninnere Lager dem benachbartem Wagenteil, sodass es bei engen Kurven zu Durchdringungen, also Kollisionen der Wagenteile, kommen kann. Ebenso verändert sich bei starrem Lenker bei Befahren von Kuppen oder Wannen der Abstand zwischen den außenliegenden Lagern und der Fahrzeughochachse (Z-Achse), sodass es zu Zwangsverwindungen der Wagenkästen kommt. Die üblichen Kulissenführungen haben den Nachteil, dass sich bei Befahren von Kuppen oder Wannen der Kulissenstein dem benachbartem Wagenteil nähert. Es kann somit bei Neigungswechsein zu Durchdringungen, also Kollisionen der Wagenteile, kommen.However, these solutions have a number of disadvantages. Thus, when cornering in the usual off-center mounting of the wishbone approaches the inner curve bearing the adjacent car part, so it is at tight curves to penetrations, ie collisions the car parts, can come. Likewise, the distance between the outer bearings and the vehicle vertical axis (Z-axis) changes with rigid handlebar when driving over hills or troughs, so that it comes to forced convolutions of the car bodies. The usual slotted guides have the disadvantage that when approaching hills or troughs of the sliding block approaches the adjacent car part. It can thus come with inclination change to penetrations, ie collisions of the car parts.

Ein gattungsgemäßes Fahrzeug ist schließlich aus der DE 30 30 015 A1 bekannt, bei der die Wagenkästen jeweils über zwei Nickgelenkarme, die jeweils mit einem Nickgelenkstab verbunden sind, miteinander gekoppelt sind. Die zwischen den jeweiligen Nickgelenkarm und den ersten Wagenkasten ist jeweils ein Dämpfer geschaltet, welcher die Auslenkungen des jeweiligen Nickgelenkarms bedämpft, sodass sich bei Kurvenfahrt gleichlaufende Auslenkungen ergeben.A generic vehicle is finally out of the DE 30 30 015 A1 known, in which the car bodies are each coupled to each other via two pitch joint arms, which are each connected to a pitch rod Nick. The between the respective Nickgelenkarm and the first car body is connected in each case a damper which damps the deflections of the respective Nickgelenkarms, so that result in cornering concurrent deflections.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, ein Fahrzeug der eingangs genannten Art zur Verfügung zu stellen, welches die oben genannten Nachteile nicht oder zumindest in deutlich geringerem Maße aufweist und insbesondere auf einfache und zuverlässige Weise eine Reduktion von Zwangsverwindungen der Wagenkästen beim Befahren von Kuppen oder Wannen ermöglicht.The present invention is therefore based on the object to provide a vehicle of the type mentioned above, which does not have the disadvantages mentioned above, or at least to a much lesser extent and in particular in a simple and reliable way a reduction of Zwangsverwindungen the car bodies when driving Dome or tubs allowed.

Die vorliegende Erfindung löst diese Aufgabe ausgehend von einem Fahrzeug gemäß dem Oberbegriff des Anspruchs 1 durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale.The present invention solves this problem starting from a vehicle according to the preamble of claim 1 by the features stated in the characterizing part of claim 1.

Der vorliegenden Erfindung liegt die technische Lehre zu Grunde, dass man auf einfache und zuverlässige Weise eine Reduktion von Zwangsverwindungen der Wagenkästen beim Befahren von Kuppen oder Wannen ermöglicht, wenn das Nickgelenk als ein sich im wesentlichen in einer Nickgelenkebene erstreckendes Stabwerk ausgebildet ist, das zwei Nickgelenkarme, zwei Nickgelenkstäbe und eine Koppeleinrichtung umfasst, wobei die Nickgelenkarme im Bereich ihres ersten Endes schwenkbar am ersten Wagenkasten angelenkt sind, jeweils einer der Nickgelenkstäbe im Bereich seines ersten Endes schwenkbar an dem freien zweiten Ende eines der Nickgelenkarme angelenkt ist, die Nickgelenkstäbe im Bereich ihres zweiten Endes schwenkbar am zweiten Wagenkasten angelenkt sind und die Koppeleinrichtung die beiden Nickgelenkarme derart miteinander koppelt, dass sie gegenläufige Schwenkbewegungen um ihre Anlenkpunkte am ersten Wagenkasten ausführen.The present invention is based on the technical teaching that allows a simple and reliable way to reduce torsional distortion of the car bodies when driving on hills or troughs, when the pitch joint is formed as a substantially extending in a pitch joint plane framework, the two pitch joint arms , two pitch joint bars and a coupling device, wherein the pitch joint arms are hinged in the region of its first end pivotally mounted on the first car body, one of the pitch joint rods in the region of its first end pivotally articulated to the free second end of the pitch joint arms, the pitch joint bars in the region of its second End pivotally hinged to the second car body and the coupling device, the two pitch joint arms coupled to each other in such a way that they perform opposite pivotal movements about their pivot points on the first car body.

Durch die gegenläufige Kopplung der Nickgelenkarme kann im Fall von Nickbewegungen zwischen den Wagenkästen zum einen eine Parallelführung der beiden Wagenkästen entlang der Fahrzeuglängsachse erzielt werden. Dies hat den Vorteil, dass sich die Anlenkpunkte des Nickgelenks an den Wagenkästen beim Befahren von Kuppen oder Wannen oder im Fall anderweitig induzierter Nickbewegungen zwischen den Wagenkästen parallel zur Fahrzeuglängsachse zueinander verschieben. Demgemäß kommt es hierbei zu keinenDue to the opposing coupling of the pitch joint arms, a parallel guidance of the two bodies along the vehicle longitudinal axis can be achieved in the case of pitching movements between the bodies. This has the advantage that move the pivot points of the pitch joint to the car bodies when driving on hills or troughs or in the case of otherwise induced pitching movements between the car bodies parallel to the vehicle longitudinal axis to each other. Accordingly, there are none

Querverschiebungen zwischen den Anlenkpunkten des Nickgelenks an dem einen Wagenkasten und den Anlenkpunkten des Nickgelenks an dem anderen Wagenkasten. Ein weiterer Vorteil der Zwangskopplung der Nickgelenkarme liegt darin, dass die Wankstützwirkung in vollem Umfang zum Tragen kommen kann.Transverse displacements between the articulation points of the pitch joint on the one car body and the articulation points of the pitch joint on the other car body. Another advantage of the positive coupling of the pitch joint arms is that the roll support effect can be fully effective.

Je nach den gewählten geometrischen Verhältnissen der Nickgelenkarme und Nickgelenkstäbe kann eine beliebige Übersetzung zwischen den Bewegungen der Nickgelenkarme vorgesehen sein. Bevorzugt ist jedoch vorgesehen, dass die Koppeleinrichtung die beiden Nickgelenkarme derart miteinander koppelt, dass sie im Wesentlichen synchrone Schwenkbewegungen um ihre Anlenkpunkte am ersten Wagenkasten ausführen. Hierdurch lassen sich vorteilhafte, weil einfach gestaltete symmetrische Anordnungen realisieren.Depending on the selected geometric relationships of the pitch joint arms and pitch joint rods, any translation between the movements of the pitch joint arms can be provided. Preferably, however, it is provided that the coupling device couples the two pitch joint arms with each other in such a way that they execute essentially synchronous pivoting movements about their articulation points on the first carriage body. This makes it possible to realize advantageous because simply designed symmetrical arrangements.

Die Kopplung der Nickgelenkarme kann über ein beliebig gestaltetes Getriebe erfolgen, welches die gegenläufigen Schwenkbewegungen erzeugt. Hierbei kann es sich um ein reibschlüssiges und/oder formschlüssiges und/oder ein hydraulisches Getriebe etc. handeln. Es kann beispielsweise auch ein Umschlingungsgetriebe oder dergleichen verwendet werden. Bevorzugt umfasst die Koppeleinrichtung jedoch eine schwenkbar an dem jeweiligen Nickgelenkarm angelenkte Koppelstange oder eine die Nickgelenkarme koppelnde Verzahnung, da hiermit besonders einfache und zuverlässige Gestaltungen erzielt werden können.The coupling of the pitch joint arms can take place via an arbitrarily designed gear, which generates the opposite pivoting movements. This may be a friction-locked and / or positive-locking and / or a hydraulic transmission, etc. It can also be used, for example, a belt drive or the like. However, the coupling device preferably comprises a coupling rod which is pivotably articulated to the respective pitch joint arm or a toothing coupling the pitch joint arms, since in this way particularly simple and reliable designs can be achieved.

Das Nickgelenk kann grundsätzlich in beliebiger geeigneter Ausrichtung angeordnet werden. Bevorzugt verläuft die Nickgelenkebene im Wesentlichen parallel zu einer Fahrzeugquerachse des Fahrzeugs, da hiermit besonders gleichmäßige Kräfteverhältnisse bei der Abstützung von Wankbewegungen erzielt werden. Vorzugsweise verläuft die Nickgelenkebene im Wesentlichen senkrecht zu einer Fahrzeughochachse des Fahrzeugs, da die im Betrieb aufzunehmenden Kräfte dann im Wesentlichen in der Ebene des Stabwerks wirken in der hiermit günstige Lastverhältnisse in den Nickgelenkarmen und Nickgelenkstäben sowie den Gelenkpunkten des Nickgelenks erzielt werden können.The pitch joint can basically be arranged in any suitable orientation. Preferably, the pitch plane is substantially parallel to a vehicle transverse axis of the vehicle, as this particularly particularly strong balance of power in the support of rolling movements can be achieved. Preferably, the pitch plane is substantially perpendicular to a vehicle vertical axis of the vehicle, since the forces to be absorbed during operation then substantially in the plane of the framework act in the hereby favorable load conditions in the pitch joint arms and pitch joint bars and the hinge points of the pitch joint can be achieved.

Die Nickgelenkarme und Nickgelenkstäben können grundsätzlich in beliebiger geeigneter Weise angeordnet werden. So können sie beispielsweise im Wesentlichen rautenförmig angeordnet werden. Weiterhin können die Nickgelenkarme voneinander entfernt am ersten Wagenkasten angelenkt sein. Bei vorteilhaften Varianten der Erfindung kreuzen sich die Nickgelenkarme zwischen ihrem ersten Ende und ihrem zweiten Ende, sodass eine besonders kompakte Anordnung entsteht.The pitch joint arms and pitch joint bars can basically be arranged in any suitable manner. For example, they can be arranged substantially diamond-shaped. Furthermore, the pitch joint arms can be articulated remote from each other on the first car body. In advantageous variants of the invention, the pitch joint arms intersect between their first end and their second end, so that a particularly compact arrangement is created.

Die Nickgelenkstäbe können ebenfalls in beliebiger geeigneter Weise am zweiten Wagenkasten angeordnet sein. Bevorzugt ist vorgesehen, dass die Anlenkpunkte der Nickgelenkstäbe am zweiten Wagenkasten zueinander benachbart angeordnet sind, sodass hier aus sich heraus zumindest eine gewisse Schwenkbeweglichkeit des Nickgelenks um die Fahrzeughochachse gegeben ist. Bevorzugt sind die Anlenkpunkte der Nickgelenkstäbe am zweiten Wagenkasten in Richtung einer Fahrzeughochachse des Fahrzeugs miteinander im Wesentlichen fluchtend angeordnet, sodass ohne weitere Zusatzmaßnahmen - wie beispielsweise eine entsprechend gelenkige Lagerung eines die Anlenkpunkte der Nickgelenkstäbe aufnehmenden Trägers am zweiten Wagenkasten - eine Schwenkbeweglichkeit des Nickgelenks um die Fahrzeughochachse gegeben ist.The pitch joint rods may also be arranged in any suitable manner on the second car body. It is preferably provided that the articulation points of the pitch joint rods are arranged adjacent to each other on the second car body, so that at least a certain pivoting mobility of the pitch joint is given to the vehicle vertical axis out of itself. Preferably, the articulation points of the pitch joint bars on the second car body in the direction of a vehicle vertical axis of the vehicle are arranged substantially in alignment with each other, so without further additional measures - such as a correspondingly articulated mounting of the articulation points of the pitch joint bars receiving carrier on the second car body - a pivoting movement of the pitch joint to the vehicle vertical axis given is.

Vorzugsweise sind der erste Wagenkasten und der zweite Wagenkasten über ein weiteres Schwenklager um eine zur Fahrzeughochachse des Fahrzeugs im Wesentlichen parallele erste Schwenkachse schwenkbar verbunden und die Anlenkpunkte der Nickgelenkstäbe am zweiten Wagenkasten im Wesentlichen auf der ersten Schwenkachse liegen. Dann ist kein zusätzliches Schwenkgelenk im Bereich des Nickgelenks erforderlich, um die Schwenkbewegung der Wagenkästen bei Kurvenfahrt zu realisieren.Preferably, the first car body and the second car body via a further pivot bearing about a vehicle vertical axis of the vehicle substantially parallel to the first pivot axis are pivotally connected and the points of articulation of the pitch joint bars on the second car body substantially on the first pivot axis. Then no additional pivot joint in the region of the pitch joint is required to realize the pivoting movement of the car bodies when cornering.

Die Nickgelenkarme können direkt am ersten Wagenkasten befestigt sein. Bevorzugt ist jedoch vorgesehen, dass die Nickgelenkarme an einem Nickgelenkträger angelenkt sind, über den sie am ersten Wagenkasten befestigt sind. Hierdurch kann in einfacher Weise eine gewisse Querelastizität, gegebenenfalls sogar eine Querdämpfung, in das Nickgelenk eingeführt werden. Dies geschieht bei bevorzugten Varianten der Erfindung einfach, indem der Nickgelenkträger über eine Federeinrichtung am ersten Wagenkasten befestigt ist, wobei die Federeinrichtung insbesondere eine Dämpfereinrichtung umfasst.The pitch joint arms can be attached directly to the first car body. Preferably, however, it is provided that the pitch joint arms are articulated on a pitch joint carrier, via which they are attached to the first car body. In this way, a certain transverse elasticity, possibly even a transverse damping, can be introduced into the pitch joint in a simple manner. This is done in preferred variants of the invention simply by the pitch joint carrier is fastened via a spring device on the first car body, wherein the spring device comprises in particular a damper device.

Bevorzugt ermöglicht die Federeinrichtung dann eine Schwenkbewegung des Nickgelenkträgers um die Fahrzeughochachse des Fahrzeugs, sodass die Querelastizität hierdurch einfach zu realisieren ist. Vorzugsweise umfasst die Federeinrichtung hierzu zwei voneinander entlang der Fahrzeugquerachse des Fahrzeugs beabstandete Federelemente, insbesondere Metallgummifederelemente.Preferably, the spring device then allows a pivoting movement of the pitch joint support about the vehicle vertical axis of the vehicle, so that the transverse elasticity is thereby easy to implement. For this purpose, the spring device preferably comprises two spring elements spaced apart from one another along the vehicle transverse axis of the vehicle, in particular metal rubber spring elements.

Um Verspannungen in dem Nickgelenk bei Nickbewegungen zu vermeiden ist bevorzugt vorgesehen, dass zumindest ein Teil der Gelenkverbindungen des Nickgelenks, insbesondere die Gelenkverbindungen der Nickgelenkstäbe, Schwenkbewegungen um in der Nickgelenkebene liegende Schwenkachsen zulässt. Bevorzugt ist hierzu zumindest ein Teil der Gelenkverbindungen des Nickgelenks, insbesondere die Gelenkverbindungen der Nickgelenkstäbe, sphärisch ausgebildet.In order to avoid tension in the pitch joint during pitching movements, it is preferably provided that at least a part of the articulated joints of the pitch joint, in particular the articulated joints of the pitch joint bars, permits pivoting movements about pivot axes lying in the pitch joint plane. At least a part of this is preferred for this purpose Articulated joints of the pitch joint, in particular the joints of the pitch joint rods, spherically formed.

Erstes AusführungsbeispielFirst embodiment

Die Figur 1 zeigt eine schematische Draufsicht auf einen Teil eines erfindungsgemäßeri Fahrzeugs in Form eines Gliederzugs 101 mit einer Fahrzeuglängsachse 101.1 und einer Fahrzeugquerachse 101.2. Das Fahrzeug 101 umfasst einen ersten Wagenkasten 102 und einen zweiten Wagenkasten 103.The FIG. 1 shows a schematic plan view of a part of a vehicle according to the invention in the form of an articulated train 101 with a vehicle longitudinal axis 101.1 and a vehicle transverse axis 101.2. The vehicle 101 includes a first body 102 and a second body 103.

Die Wagenkästen 102 und 103 sind in ihrem Dachbereich über ein Nickgelenk 104 verbunden, während sie in ihrem Bodenbereich, in dem sie auf- nicht dargestellten - Fahrwerken abgestützt sind, über ein - ebenfalls nicht dargestelltes - Schwenkgelenk um eine senkrecht zur Zeichnungsebene verlaufende Fahrzeughochachse schwenkbar verbunden sind.The car bodies 102 and 103 are connected in their roof area via a pitch joint 104, while in their bottom area, in which they are supported - not shown - are pivotally connected via a - also not shown - swivel joint about a perpendicular to the plane extending vehicle vertical axis are.

Das Nickgelenk 104 ist als ein sich im wesentlichen in einer zur Zeichnungsebene parallelen Nickgelenkebene erstreckendes Stabwerk ausgebildet. Es umfasst zwei einander zwischen ihren Enden kreuzende Nickgelenkarme 104.1 und 104.2, zwei Nickgelenkstäbe 104.3 und 104.4 sowie eine Koppeleinrichtung in Form einer Koppelstange 104.5.The pitch joint 104 is formed as a generally extending in a pitch plane parallel to the plane of the pitch joint framework. It comprises two pitch joint arms 104.1 and 104.2 crossing each other between their ends, two pitch joint rods 104.3 and 104.4 and a coupling device in the form of a coupling rod 104.5.

Die Nickgelenkarme 104.1 und 104.2 weisen im Wesentlichen die gleiche Wirklänge - also im Wesentlichen den gleichen Abstand zwischen ihren jeweiligen Gelenkpunkten - auf und sind im Bereich ihres ersten Endes schwenkbar an einem Nickgelenkträger 104.6 angelenkt, der wiederum über Metall-Gummi-Federelemente 105 federnd am ersten Wagenkasten 102 befestigt ist.The pitch joint arms 104.1 and 104.2 have substantially the same effective length - ie substantially the same distance between their respective pivot points - and are pivotally hinged in the region of its first end to a pitch joint support 104.6, which in turn via metal-rubber spring elements 105 resiliently on the first Car body 102 is attached.

Der erste Nickgelenkstab 104.3 ist im Bereich seines ersten Endes schwenkbar an dem freien zweiten Ende des ersten Nickgelenkarms 104.1 angelenkt, während der zweite Nickgelenkstab 104.4 ist im Bereich seines ersten Endes schwenkbar an dem freien zweiten Ende des zweiten Nickgelenkarms 104.2 angelenkt ist. Auch die Nickgelenkstäbe 104.3 und 104.4 weisen im Wesentlichen die gleiche Wirklänge auf.The first pitch rod 104.3 is pivoted in the region of its first end to the free second end of the first pitch joint arm 104.1, while the second pitch rod 104.4 is pivoted in the region of its first end pivotally to the free second end of the second pitch joint 104.2. The nickel joint rods 104.3 and 104.4 also have essentially the same effective length.

Die Nickgelenkstäbe 104:3 und 104.4 sind im Bereich ihres zweiten Endes schwenkbar am zweiten Wagenkasten 103 angelenkt. Dabei sind die Anlenkpunkte der Nickgelenkstäbe 104.3 und 104.4 am zweiten Wagenkasten 103 derart zueinander benachbart angeordnet, dass sie in Richtung einer Fahrzeughochachse des Fahrzeugs 101 miteinander im Wesentlichen fluchten. Hierdurch ist ohne weitere Zusatzmaßnahmen eine Schwenkbeweglichkeit des Nickgelenks 104 um die Fahrzeughochachse gegeben.The pitch joints 104: 3 and 104.4 are pivotally hinged to the second body 103 in the region of its second end. The articulation points of the pitch joints 104.3 and 104.4 on the second body 103 are arranged adjacent to each other in such a way that they are substantially aligned with one another in the direction of a vehicle vertical axis of the vehicle 101. As a result, a pivoting movement of the pitch joint 104 is given to the vehicle vertical axis without further additional measures.

Die Anlenkpunkte der Nickgelenkstäbe 104.3 und 104.4 am zweiten Wagenkasten 103 liegen auf der Schwenkachse, die durch das - nicht dargestellte - untere Schwenkgelenk zwischen dem ersten Wagenkasten 102 und dem zweiten Wagenkasten 103 definiert ist. Demgemäß sind der erste Wagenkasten 102 und der zweite Wagenkasten 103 durch das untere Schwenkgelenk und das Nickgelenk 104 um eine senkrecht zur Zeichnungsebene verlaufende Fahrzeughochachse schwenkbar verbunden.The articulation points of the pitch joints 104.3 and 104.4 on the second body 103 are on the pivot axis, which is defined by the - not shown - lower pivot joint between the first car body 102 and the second car body 103. Accordingly, the first car body 102 and the second car body 103 are pivotally connected by the lower pivot joint and the pitch joint 104 about a vehicle vertical axis perpendicular to the plane of the drawing.

Diese Anordnung der Anlenkpunkte der Nickgelenkstäbe 104.3 und 104.4 am zweiten Wagenkasten 103 hat unter anderem den Vorteil, dass kein zusätzliches Schwenkgelenk im Bereich des Nickgelenks erforderlich, um die Schwenkbewegung der Wagenkästen bei Kurvenfahrt zu realisieren. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung durchaus eine andere, insbesondere voneinander in der Nickgelenkebene beabstandete Anlenkung der Nickgelenkstäbe vorgesehen sein kann, wobei gegebenenfalls dann die Schwenkbeweglichkeit um die Fahrzeughochachse über ein zusätzliches Schwenkgelenk realisiert wird.This arrangement of the articulation points of the pitch joints 104.3 and 104.4 on the second car body 103 has, inter alia, the advantage that no additional pivot joint in the region of the pitch joint required to realize the pivoting movement of the car bodies when cornering. It is understood, however, that in other variants of the invention quite another, in particular spaced from each other in the pitch plane articulation of the pitch joint rods may be provided, where appropriate, then the pivoting movement is realized about the vehicle vertical axis via an additional pivot joint.

Die Koppelstange 104.5 ist schwenkbar an den Nickgelenkarmen 104.1 und 104.2 angelenkt und koppelt die beiden Nickgelenkarme 104.1 und 104.2 derart miteinander, dass sie im Wesentlichen synchrone gegenläufige Schwenkbewegungen um ihre Anlenkpunkte am ersten Wagenkasten 102 ausführen.The coupling rod 104.5 is pivotally articulated to the pitch joint arms 104.1 and 104.2 and couples the two pitch joint arms 104.1 and 104.2 together so that they perform substantially synchronous opposite pivoting movements about their pivot points on the first car body 102.

Durch die gegenläufige Kopplung der Nickgelenkarme 104.1 und 104.2 kann im Fall von Nickbewegungen zwischen den Wagenkästen zum einen eine Parallelführung der beiden Wagenkästen 102 und 103 entlang der Fahrzeuglängsachse 101.1 erzielt werden. Dies hat den Vorteil, dass sich die Anlenkpunkte des Nickgelenks 104 an den Wagenkästen beim Befahren von Kuppe n oder Wannen oder im Fall anderweitig induzierter Nickbewegungen zwischen den Wagenkästen parallel zur Fahrzeuglängsachse 101.1 zueinander verschieben. Demgemäß kommt es hierbei zu keinen entlang der Fahrzeugquerachse 101.2 auftretenden Querverschiebungen zwischen den Anlenkpunkten des Nickgelenks 104 an dem ersten Wagenkasten 102 und den Anlenkpunkten des Nickgelenks 104 an dem zweiten Wagenkasten 103.By the opposite coupling of the pitch joint arms 104.1 and 104.2 can be achieved in the case of pitching movements between the car bodies on the one hand a parallel guidance of the two car bodies 102 and 103 along the vehicle longitudinal axis 101.1. This has the advantage that the articulation points of the pitch joint 104 to the car bodies when driving on dome n or trays or in the case of otherwise induced pitching movements between the car bodies parallel to the vehicle longitudinal axis 101.1 move each other. Accordingly, there is no transverse displacement occurring between the articulation points of the pitch joint 104 on the first vehicle body 102 and the articulation points of the pitch joint 104 on the second vehicle body 103 along the vehicle transverse axis 101.

Hierdurch ist auf einfache und zuverlässige Weise sichergestellt , dass es beim Befahren von Kuppen oder Wannen im Wesentlichen zu keinen Zwangsverwindungen der Wagenkästen 102 und 103 kommt. Ein weiterer Vorteil der Zwangskopplung der Nickgelenkarme 104.1 und 104.2 liegt darin, dass die Wankstützwirkung in vollem Umfang zum Tragen kommen kann.As a result, it is ensured in a simple and reliable manner that there is essentially no forced twisting of the vehicle bodies 102 and 103 when driving over hills or troughs. Another advantage of the positive coupling of the pitch joint arms 104.1 and 104.2 is that the roll support effect can be fully effective.

Die synchrone gegenläufige Kopplung der Nickgelenkarme 104.1 und 104.2 wird dadurch erzielt, dass die Koppelstange 104.5 so an Fortsätzen der Nickgelenkarme 104.1 und 104.2 angelenkt ist, dass die Verbindungsgerade ihrer Anlenkpunkte an den Nickgelenkarmen 104.1 und 104.2 die Verbindungsgerade der Anlenkpunkte der Nickgelenkarme 104.1 und 104.2 am Nickgelenkträger 104.6 im Wesentlichen mittig schneidet.The synchronous counter-rotating coupling of the pitch joint arms 104.1 and 104.2 is achieved in that the coupling rod 104.5 is hinged to extensions of the pitch joint arms 104.1 and 104.2, that the connecting line of their articulation points on the pitch joint arms 104.1 and 104.2 the connecting line of the articulation points of the pitch joint arms 104.1 and 104.2 on the pitch joint carrier 104.6 substantially centrally cuts.

Die Nickgelenkebene des Nickgelenks 104 verläuft im Wesentlichen senkrecht zur Fahrzeughochachse des Fahrzeugs 101, sodass die im Betrieb aufzunehmenden Kräfte im Wesentlichen in der Ebene des durch das Nickgelenk 104 gebildeten Stabwerks wirken. Demgemäß werden günstige Lastverhältnisse in den Nickgelenkarmen 104.1 und 104.2 und Nickgelenkstäben 104.3 und 104.4 sowie den Gelenkpunkten des Nickgelenks 104 erzielt.The pitch plane of the pitch joint 104 extends substantially perpendicular to the vehicle vertical axis of the vehicle 101, so that the forces to be absorbed during operation act substantially in the plane of the framework formed by the pitch joint 104. Accordingly, favorable load conditions in the pitch joint arms 104.1 and 104.2 and pitch joint bars 104.3 and 104.4 and the hinge points of the pitch joint 104 are achieved.

Durch die einander kreuzende Anordnung der Nickgelenkarme 104.1 und 104.2 wird zudem eine besonders kompakte Anordnung erzielt, sodass zum einen der angrenzende Bauraum für andere Komponenten zur Verfügung steht und zudem auch bei engen Kurvenradien keine Durchdringungen zu erwarten sind.By the crossing arrangement of the pitch joint arms 104.1 and 104.2 also a particularly compact arrangement is achieved, so that on the one hand the adjacent space for other components is available and also no penetrations are to be expected even with tight curve radii.

Die Anordnung der Nickgelenkarme 104.1 und 104.2 an dem über die Metall-Gummi-Federelemente 105 elastisch gelagerten Nickgelenkträger 104.6 hat den Vorteil, dass hierdurch in einfacher Weise eine gewisse Querelastizität und eine Querdämpfung in das Nickgelenk 104 eingeführt wird. Die in Richtung der Fahrzeugquerachse 101.2 beabstandeten Metall-Gummi-Federelemente 105 (z. B. jeweils ein Megi® Konus) ermöglichen eine Querbewegung des Nickgelenkträgers 104.6 in Richtung der Fahrzeugquerachse 101.2 sowie eine Drehbewegung des Nickgelenkträgers 104.6 um die der Fahrzeughochachse. Dies ermöglicht leichte, bedämpfte Wankauslenkungen zwischen den Wagenkästen 102 und 103.The arrangement of the pitch joint arms 104.1 and 104.2 on the over the metal-rubber spring elements 105 elastically mounted pitch joint carrier 104.6 has the advantage that in a simple manner, a certain transverse elasticity and transverse damping in the pitch joint 104 is introduced. The metal-rubber spring elements 105 (for example, in each case a Megi® cone), which are spaced in the direction of the vehicle transverse axis 101.2, permit a transverse movement of the pitch joint support 104.6 in the direction of the vehicle transverse axis 101.2 and a rotational movement of the pitch joint support 104.6 about that of the vehicle's vertical axis. This allows for light, damped Wank deflections between the car bodies 102 and 103.

Die Nickgelenkarme 104.1 und 104.2 sind in einfachen Schwenklagern am Nickgelenkträger 104.6 angelenkt. Um Verspannungen in dem Nickgelenk 104 bei Nickbewegungen zu vermeiden, sind die Gelenkverbindungen der Nickgelenkstäbe 104.3 und 104.4 als sphärische Gelenke ausgebildet, die Schwenkbewegungen um in der Nickgelenkebene liegende Schwenkachsen zulassen.The pitch joint arms 104.1 and 104.2 are articulated in simple pivot bearings on the pitch joint carrier 104.6. In order to avoid tension in the pitch joint 104 during pitching movements, the articulations of the pitch joints 104.3 and 104.4 are formed as spherical joints that allow pivotal movements about pivot axes lying in the pitch joint plane.

Da sie jeweils nur Zug- bzw. Druckkräfte übertragen müssen, sind die Nickgelenkstäbe 104.3 und 104.4 sowie die Koppelstange 104.5 als vergleichsweise leichte Stangenelemente ausgebildet. Um eine Justierung des Nickgelenks 104 zu ermöglichen, sind die Nickgelenkstäbe 104.3 und 104.4 sowie die Koppelstange 104.5 längenverstellbar ausgeführt.Since they only have to transmit tensile or compressive forces, the pitch rods 104.3 and 104.4 and the coupling rod 104.5 are designed as comparatively light rod elements. In order to enable an adjustment of the pitch joint 104, the pitch rods 104.3 and 104.4 and the coupling rod 104.5 are designed to be adjustable in length.

Das Fahrzeug 301 entspricht in Aufbau und Funktionsweise grundsätzlich dem Fahrzeug 101 aus Figur 1, sodass hier lediglich auf die Unterscheide eingegangen werden soll. Insbesondere sind in Figur 3 im Vergleich zur Ausführung aus Figur 1 gleiche Bauteile mit um den Betrag 200 erhöhten Bezugszeichen versehen und es wird hinsichtlich deren Funktion und Gestaltung auf die obigen Ausführungen verwiesen.The FIG. 3 shows a schematic plan view of a portion of another vehicle according to the invention 301 with a vehicle longitudinal axis 301.1 and a vehicle transverse axis 301.2. The vehicle 301 basically corresponds in construction and mode of operation to the vehicle 101 FIG. 1 , so that only the differences should be discussed here. In particular, in FIG. 3 in comparison to the execution FIG. 1 The same components provided with increased by the amount 200 reference numerals and reference is made in terms of their function and design to the above statements.

Das Fahrzeug 301 umfasst einen ersten Wagenkasten 302 und einen zweiten Wagenkasten 303. Die Wagenkästen 302 und 303 sind in ihrem Dachbereich über ein Nickgelenk 304 verbunden, während sie in ihrem Bodenbereich, in dem sie auf - nicht dargestellten - Fahrwerken abgestützt sind, über ein - ebenfalls nicht dargestelltes - Schwenkgelenk um eine senkrecht zur Zeichnungsebene verlaufende Fahrzeughochachse schwenkbar verbunden sind.The vehicle 301 comprises a first car body 302 and a second car body 303. The car bodies 302 and 303 are connected in their roof area via a pitch joint 304, while in their bottom area, in which they are supported on - not shown - bogies, via a - also not shown - swivel joint are pivotally connected about a perpendicular to the plane extending vehicle vertical axis.

Das Nickgelenk 304 ist als ein sich im wesentlichen in einer zur Zeichnungsebene parallelen Nickgelenkebene erstreckendes rautenförmiges Stabwerk ausgebildet. Es umfasst zwei Nickgelenkarme 304.1 und 304.2, zwei Nickgelenkstäbe 304.3 und 304.4 sowie eine Kops peleinrichtung in Form einer Zahnradpaarung 304.5 mit dem Übersetzungsverhältnis 1.The pitch joint 304 is formed as a diamond-shaped framework extending substantially in a pitch plane parallel to the plane of the drawing. It comprises two pitch joint arms 304.1 and 304.2, two pitch joint bars 304.3 and 304.4 and a Kops peleinrichtung in the form of a gear pair 304.5 with the gear ratio of the first

Die Nickgelenkarme 304.1 und 304.2 weisen im Wesentlichen die gleiche Wirklänge - also im Wesentlichen den gleichen Abstand zwischen ihren jeweiligen Gelenkpunkten - auf und sind im Bereich ihres ersten Endes schwenkbar am ersten Wagenkasten 302 befestigt.The pitch joint arms 304.1 and 304.2 have substantially the same effective length - that is, substantially the same distance between their respective hinge points - and are pivotally attached to the first car body 302 in the region of its first end.

Der erste Nickgelenkstab 304.3 ist im Bereich seines ersten Endes schwenkbar an dem freien zweiten Ende des ersten Nickgelenkarms 304.1 angelenkt, während der zweite Nickgelenkstab 304.4 ist im Bereich seines ersten Endes schwenkbar an dem freien zweiten Ende des zweiten Nickgelenkarms 304.2 angelenkt ist. Auch die Nickgelenkstäbe 304.3 und 304.4 weisen im Wesentlichen die gleiche Wirklänge auf.The first pitch joint rod 304.3 is pivotally hinged in the region of its first end to the free second end of the first pitch joint arm 304.1, while the second pitch rod 304.4 is pivoted in the region of its first end pivotally to the free second end of the second pitch joint arm 304.2. Also, the pitch joint bars 304.3 and 304.4 have substantially the same effective length.

Die Nickgelenkstäbe 304.3 und 304.4 sind im Bereich ihres zweiten Endes schwenkbar am zweiten Wagenkasten 303 angelenkt. Dabei sind die Anlenkpunkte der Nickgelenkstäbe 304.3 und 304.4 am zweiten Wagenkasten 303 derart zueinander benachbart angeordnet, dass sie in Richtung einer Fahrzeughochachse des Fahrzeugs 301 miteinander im Wesentlichen fluchten. Hierdurch ist ohne weitere Zusatzmaßnahmen eine Schwenkbeweglichkeit des Nickgelenks 304 um die Fahrzeughochachse gegeben.The pitch joints 304.3 and 304.4 are pivotally hinged to the second car body 303 in the region of its second end. In this case, the articulation points of the pitch joint bars 304.3 and 304.4 on the second car body 303 are arranged adjacent to one another in such a way that they essentially coincide with one another in the direction of a vehicle vertical axis of the vehicle 301 aligned. As a result, a pivoting movement of the pitch joint 304 is given about the vehicle vertical axis without further additional measures.

Die Anlenkpunkte der Nickgelenkstäbe 304.3 und 304.4 am zweiten Wagenkasten 303 liegen auf der Schwenkachse, die durch das- nicht dargestellte - untere Schwenkgelenk zwischen dem ersten Wagenkasten 302 und dem zweiten Wagenkasten 303 definiert ist. Demgemäß sind der erste Wagenkasten 302 und der zweite Wagenkasten 303 durch das untere Schwenkgelenk und das Nickgelenk 304 um eine senkrecht zur Zeichnungsebene verlaufende Fahrzeughochachse schwenkbar verbunden.The articulation points of the pitch joint bars 304.3 and 304.4 on the second car body 303 are on the pivot axis, which is defined by the - not shown - lower pivot joint between the first car body 302 and the second car body 303. Accordingly, the first car body 302 and the second car body 303 are pivotally connected by the lower pivot joint and the pitch joint 304 about a vehicle vertical axis perpendicular to the plane of the drawing.

Diese Anordnung der Anlenkpunkte der Nickgelenkstäbe 304.3 und 304.4 am zweiten Wagenkasten 303 hat unter anderem den Vorteil, dass kein zusätzliches Schwenkgelenk im Bereich des Nickgelenks erforderlich, um die Schwenkbewegung der Wagenkästen bei Kurvenfahrt zu realisieren. Es versteht sich jedoch, dass bei anderen Varianten der Erfindung durchaus eine andere, insbesondere voneinander in der Nickgelenkebene beabstandete Anlenkung der Nickgelenkstäbe vorgesehen sein kann, wobei gegebenenfalls dann die Schwenkbeweglichkeit um die Fahrzeughochachse über ein zusätzliches Schwenkgelenk realisiert wird.This arrangement of the articulation points of the pitch joints 304.3 and 304.4 on the second car body 303 has, inter alia, the advantage that no additional pivot joint in the region of the pitch joint required to realize the pivoting movement of the car bodies when cornering. It is understood, however, that in other variants of the invention quite another, in particular spaced from each other in the pitch plane articulation of the pitch joint rods may be provided, where appropriate, then the pivoting movement is realized about the vehicle vertical axis via an additional pivot joint.

Die Zahnradpaarung 304.5 umfasst zwei Zahnräder, die jeweils drehfest mit einem der Nickgelenkarme 304.1 und 304.2 verbunden sind. Die Zahnradpaarung 304.5 koppelt die beiden Nickgelenkarme 304.1 und 304.2 derart miteinander, dass sie synchrone gegenläufige Schwenkbewegungen um ihre Anlenkpunkte am ersten Wagenkasten 302 ausführen.The gear pair 304.5 comprises two gears, which are each rotatably connected to one of the pitch joint arms 304.1 and 304.2. The gear pair 304.5 couples the two pitch joint arms 304.1 and 304.2 with each other so that they perform synchronous counter-rotating pivotal movements about their pivot points on the first car body 302.

Durch die gegenläufige Kopplung der Nickgelenkarme 304.1 und 304.2 kann im Fall von Nickbewegungen zwischen den Wagenkästen zum einen eine Parallelführung der beiden Wagenkästen 302 und 303 entlang der Fahrzeuglängsachse 301.1 erzielt werden. Dies hat den Vorteil, dass sich die Anlenkpunkte des Nickgelenks 304 an den Wagenkästen beim Befahren von Kuppen oder Wannen oder im Fall anderweitig induzierter Nickbewegungen zwischen den Wagenkästen parallel zur Fahrzeuglängsachse 301.1 zueinander verschieben. Demgemäß kommt es hierbei zu keinen entlang der Fahrzeugquerachse 301.2 auftretenden Querverschiebungen zwischen den Anlenkpunkten des Nickgelenks 304 an dem ersten Wagenkasten 302 und den Anlenkpunkten des Nickgelenks 304 an dem zweiten Wagenkasten 303.By the opposite coupling of the pitch joint arms 304.1 and 304.2 can be achieved in the case of pitching movements between the car bodies on the one hand a parallel guidance of the two car bodies 302 and 303 along the vehicle longitudinal axis 301.1. This has the advantage that the articulation points of the pitch joint 304 to the car bodies when driving on hills or troughs or in the case of otherwise induced pitching movements between the car bodies parallel to the vehicle longitudinal axis 301.1 move each other. Accordingly, transverse displacements occurring between the articulation points of the pitch joint 304 on the first carriage body 302 and the articulation points of the pitch joint 304 on the second carriage body 303 do not occur along the vehicle transverse axis 301.2.

Hierdurch ist auf einfache und zuverlässige Weise sichergestellt, dass es beim Befahren von Kuppen oder Wannen im Wesentlichen zu keinen Zwangsverwindungen der Wagenkästen 302 und 303 kommt. Ein weiterer Vorteil der Zwangskopplung der Nickgelenkarme 304.1 und 304.2 liegt darin, dass die Wankstützwirkung in vollem Umfang zum Tragen kommen kann.As a result, it is ensured in a simple and reliable manner that when driving over hills or troughs substantially no forced twisting the car bodies 302 and 303 is coming. Another advantage of the positive coupling of the pitch joint arms 304.1 and 304.2 is that the roll support effect can be fully utilized.

Die Nickgelenkebene des Nickgelenks 304 verläuft im Wesentlichen senkrecht zur Fahrzeughochachse des Fahrzeugs 301, sodass die im Betrieb aufzunehmenden Kräfte im Wesentlichen in der Ebene des durch das Nickgelenk 304 gebildeten Stabwerks wirken. Demgemäß werden günstige Lastverhältnisse in den Nickgelenkarmen 304.1 und 304.2 und Nickgelenkstäben 304.3 und 304.4 sowie den Gelenkpunkten des Nickgelenks 304 erzielt.The pitch plane of the pitch joint 304 extends substantially perpendicular to the vehicle vertical axis of the vehicle 301, so that the forces to be absorbed during operation act substantially in the plane of the framework formed by the pitch joint 304. Accordingly, favorable load conditions in the pitch joint arms 304.1 and 304.2 and pitch joint bars 304.3 and 304.4 and the hinge points of the pitch joint 304 are achieved.

Die Nickgelenkarme 304.1 und 304.2 sind in einfachen Schwenklagern am Nickgelenkträger 304.6 angelenkt. Um Verspannungen in dem Nickgelenk 304 bei Nickbewegungen zu vermeiden, sind die Gelenkverbindungen der Nickgelenkstäbe 304.3 und 304.4 als sphärische Gelenke ausgebildet, die Schwenkbewegungen um in der Nickgelenkebene liegende Schwenkachsen zulassen.The pitch joint arms 304.1 and 304.2 are articulated in simple pivot bearings on the pitch joint support 304.6. In order to avoid tension in the pitch joint 304 during pitching movements, the articulations of the pitch joints 304.3 and 304.4 are formed as spherical joints which allow pivotal movements about pivot axes lying in the pitch joint plane.

Da sie jeweils nur Zug- bzw. Druckkräfte übertragen müssen, sind die Nickgelenkstäbe 304.3 und 304.4 als vergleichsweise leichte Stangenelemente ausgebildet. Um eine Justierung des Nickgelenks 304 zu ermöglichen, sind die Nickgelenkstäbe 304.3 und 304.4 längenverstellbar ausgeführt.Since they only have to transmit tensile or compressive forces, the pitch rods 304.3 and 304.4 are designed as comparatively light rod elements. In order to allow an adjustment of the pitch joint 304, the pitch rods 304.3 and 304.4 are made adjustable in length.

Die vorliegende Erfindung wurde vorstehend ausschließlich anhand von Beispielen für Schienenfahrzeuge beschrieben. Es versteht sich schließlich weiterhin, 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. Finally, it goes without saying that the invention can also be used in conjunction with any other vehicles.
