Description

Die Erfindung betrifft ein Drehgestell mit zwei Längsträgern, mit mindestens einem die Längsträger verbindenden Querträger, und mit mindestens einem Drehstab, wobei der Drehstab parallel zu dem Querträger verläuft.The invention relates to a bogie with two longitudinal members, with at least one cross member connecting the longitudinal members, and with at least one torsion bar, wherein the torsion bar extends parallel to the cross member.

Ein solches Drehgestell ist beispielsweise aus der DE 43 11 521 C1 bekannt.Such a bogie is for example from the DE 43 11 521 C1 known.

Der Drehstab wird auch als Wankstütze bezeichnet und dient dazu, die Wankbewegungen eines auf dem Drehgestell aufgesetzten Wagenkastens zu reduzieren. In Verbindung mit geeigneten Aktuatoren, wie zum Beispiel Hydraulikzylindern, kann der Wagenkasten auch aktiv geneigt werden. Diese sogenannte Neigetechnik erhöht den Komfort der Reisenden bei schneller Kurvenfahrt.The torsion bar is also referred to as a roll support and serves to reduce the rolling movements of a mounted on the bogie car body. In conjunction with suitable actuators, such as hydraulic cylinders, the car body can also be actively tilted. This so-called tilting technique increases the comfort of the travelers with fast cornering.

Bei modernen Drehgestellen muss aufgrund steigender Anforderungen an Antriebsleistung, Bremsleistung, Komfort und anderem mehr eine zunehmend größere Zahl von Komponenten und Baugruppen in dem Drehgestell untergebracht werden. Gleichzeitig sollen die Drehgestelle so kompakt und leicht wie irgend möglich ausgeführt sein. Wesentliche Gründe hierfür sind die aus der reduzierten Masse der Drehgestelle resultierenden Energieeinsparungen und die Normierung der Drehgestelle durch die UIC.In modern bogies an increasing number of components and assemblies must be accommodated in the bogie due to increasing demands on drive power, braking performance, comfort and more. At the same time, the bogies should be as compact and lightweight as possible. The main reasons for this are the energy savings resulting from the reduced mass of the bogies and the standardization of the bogies by the UIC.

Der Erfindung liegt die Aufgabe zu Grunde, ein Drehgestell bereitzustellen, welches diesen teilweise einander widersprechenden Anforderungen bestmöglich entspricht und dass hinsichtlich des verfügbaren Bauraums mehr Freiheitsgrade als herkömmliche Drehgestelle aufweist.The invention is based on the object to provide a bogie that corresponds to these partially conflicting requirements as best as possible and that has more degrees of freedom than conventional bogies in terms of available space.

Diese Aufgabe wird erfindungsgemäß bei einem Drehgestell mit zwei Längsträgern, mit mindestens einem die Längsträger verbindenden Querträger und mit mindestens einem Drehstab, wobei der Drehstab parallel zu dem Querträger verläuft, dadurch gelöst, dass mindestens einer der Querträger an seinen Enden je eine Kröpfung aufweist, und dass der mindestens Drehstab im Bereich der Kröpfungen innerhalb des Querträgers angeordnet ist.This object is achieved with a bogie with two side rails, with at least one longitudinal beam connecting the cross member and at least one torsion bar, wherein the torsion bar extends parallel to the cross member, characterized in that at least one of the cross member has at its ends depending on a crank, and the at least torsion bar is arranged in the region of the cranks within the crossbeam.

Durch die erfindungsgemäßen Kröpfungen ist es beispielsweise möglich, bei Drehgestellen mit Rädern, die einen großen Durchmesser aufweisen, die Verbindungspunkte zwischen Querträgern und Längsträgern ausreichend weit von den Radsätzen anzuordnen. Zusätzliche Bremseinrichtungen können auch problemlos zwischen Rad und Querträgern angebaut werden.By means of the cranks according to the invention, it is possible, for example, for bogies with wheels which have a large diameter, to arrange the connecting points between cross members and longitudinal members sufficiently far from the wheel sets. Additional braking devices can also be easily installed between the wheel and cross members.

Gleichzeitig kann in der Mitte des Drehgestells in dem Bereich zwischen den Querträgern durch die erfindungsgemäße Kröpfung der Querträger ausreichend Bauraum für Kupplungen zwischen zwei auf dem Drehgestell aufliegenden Wagenkästen, eine Längslenkerverbindung zwischen Drehgestell und Wagenkasten und anderes mehr geschaffen werden.At the same time can in the middle of the bogie in the area between the cross beams by the invention Camber of the cross member sufficient space for couplings between two resting on the bogie car bodies, a trailing arm connection between bogie and car body and other more created.

Dadurch ist es möglich, bei gleichen Außenabmessungen des Drehgestells ausreichend Platz zwischen den Querträgern bereitzustellen und gleichzeitig die Verwendung großer Räder in den Radsätzen oder den Anbau von zusätzlichen Bremseinrichtungen zu ermöglichen.This makes it possible to provide sufficient space between the cross members with the same outer dimensions of the bogie and at the same time to allow the use of large wheels in the wheelsets or the cultivation of additional braking devices.

Als besonders vorteilhaft hat sich erwiesen, wenn das Drehgestell zwei gekröpfte Querträger aufweist, weil dadurch der in der Mitte zwischen den Längsträgern und den Querträgern vorhandenen Bauraum weiter zu vergrößert werden kann.It has proven to be particularly advantageous if the bogie has two cranked cross members, because thereby the existing in the middle between the longitudinal members and the cross members space can be further increased.

Da bei herkömmlichen Drehgestellen nur ein Wagenkasten auf dem Drehgestell aufliegt, ist es in aller Regel ausreichend, wenn nur an einem Querträger ein Drehstab angeordnet ist. Selbstverständlich kann bei Bedarf auch in beiden Querträgern ein Drehstab vorgesehen sein. Dies ist besonders vorteilhaft bei Jakobs-Drehgestellen auf denen bekanntermaßen die Enden von zwei Wagenkästen aufliegen.Since in conventional bogies only a car body rests on the bogie, it is usually sufficient if a torsion bar is arranged only on a cross member. Of course, if necessary, a torsion bar can also be provided in both cross members. This is particularly advantageous in Jakobs bogies where known to rest the ends of two car bodies.

Als besonders vorteilhaft hat es sich erwiesen, wenn die Kröpfungen der Querträger in einer Ebene liegen, die im Wesentlichen parallel zu den Schienen verläuft. Dadurch wird durch das Kröpfen der Querträger der Bauraumbedarf der Querträger in vertikaler Richtung nicht vergrößert, was einer flachen Bauweise des Drehgestells und damit der niedrigen Anordnung eines Wagenkastens entgegenkommt.It has proved to be particularly advantageous if the cranks of the cross members lie in a plane which runs essentially parallel to the rails. As a result, the space requirement of the cross member in the vertical direction is not increased by the crimping of the cross member, which accommodates a flat design of the bogie and thus the low arrangement of a car body.

Alternativ ist es möglich, den Drehstab im Bereich der Kröpfung drehbar in dem Querträger zu lagern, den Drehstab drehbar in den Längsträgern zu lagern oder den Drehstab drehbar in separaten Lagerböcken zu lagern, die fest mit den Längsträgern und/oder einem Querträger verbunden sind.Alternatively, it is possible to rotatably support the torsion bar in the region of the crank in the cross member, the torsion bar to store rotatably in the longitudinal members or rotatably support the torsion bar in separate bearing blocks, which are fixedly connected to the longitudinal members and / or a cross member.

Welcher dieser alternativen Ausgestaltungen im Einzelfall der Vorzug gegeben wird, ist von den Umständen des Einzelfalls abhängig.Which of these alternative embodiments is preferred in a particular case depends on the circumstances of the individual case.

Um die Kopplung des Wagenkastens mit dem Drehstab auf einfache Weise zu ermöglichen, sind an den Enden der Drehstäbe jeweils ein Hebel vorgesehen, wobei die Hebel drehfest mit dem Drehstab verbunden sind.In order to enable the coupling of the car body with the torsion bar in a simple manner, a lever are provided at the ends of the torsion bars, wherein the levers are rotatably connected to the torsion bar.

Des Weiteren ist vorgesehen, dass die dem Drehstab abgewandten Enden der Hebel über Verbindungsmittel mit einem Wagenkasten gelenkig verbunden sind. Diese Verbindungsmittel können herkömmliche Pendelstützen sein oder als längenveränderlicher Aktuator, insbesondere als Hydraulikzylinder, ausgebildet sein. Wenn die Verbindungsmittel als längenveränderliche Aktuatoren ausgebildet sind, lässt sich durch geeignete Ansteuerung der Aktuatoren eine Neigung des Wagenkastens gezielt einstellen.Furthermore, it is provided that the ends of the levers facing away from the torsion bar are articulated by connecting means to a car body. These connecting means may be conventional pendulum supports or be designed as a variable-length actuator, in particular as a hydraulic cylinder. If the connecting means are designed as variable-length actuators, an inclination of the car body can be adjusted in a targeted manner by suitable control of the actuators.

Um den Komfort der Reisenden zu erhöhen, kann mindestens zwischen einem Hebel und dem Drehgestell ein Stoßdämpfer angeordnet sein.To increase the comfort of the travelers, a shock absorber may be arranged at least between a lever and the bogie.

Wenn die erfindungsgemäßen gekröpften Querträger in einem Jakobs-Drehgestell eingesetzt werden, empfiehlt es sich zwei gekröpfte Querträger und zwei Drehstäbe vorzusehen, wobei die Drehstäbe für die beiden auf dem Jakobs-Drehgestell aufliegenden Wagenkästen durch die Kröpfungen der beiden Querträger hindurchgeführt sind.If the cranked cross member according to the invention are used in a Jakobs bogie, it is recommended to provide two cranked cross member and two torsion bars, the torsion bars are passed for the two resting on the Jakobs bogie car bodies through the cranks of the two cross member.

Beschreibung der AusführungsbeispieleDescription of the embodiments

In Figur 1 ist ein H-förmiger Drehgestellrahmen 1 in einer Isometrie dargestellt. Aus Gründen der Übersichtlichkeit sind nur die wesentlichsten Bauteile, die zur Erläuterung der Erfindung erforderlich sind, dargestellt. Radsätze, Primärfedern und Sekundärfedern sowie Antriebsmotoren sind in Figur 1 nicht dargestellt.In FIG. 1 an H-shaped bogie frame 1 is shown in an isometric view. For clarity, only the most essential components that are necessary to explain the invention are shown. wheelsets, Primary springs and secondary springs as well as drive motors are in FIG. 1 not shown.

Der Rahmen besteht aus zwei parallel zueinander angeordneten Längsträgern 3, die wiederum durch zwei Querträger 5 miteinander verbunden sind.The frame consists of two mutually parallel longitudinal members 3, which in turn are interconnected by two cross members 5.

Die Bereiche, in denen die Längsträger 3 auf den Primärfedern (nicht dargestellt) aufliegen, sind in Figur 1 mit dem Bezugszeichen 7 versehen.The areas in which the longitudinal members 3 rest on the primary springs (not shown) are in FIG. 1 provided with the reference numeral 7.

In den mit dem Bezugszeichen 9 versehenen Bereichen liegen die ebenfalls nicht dargestellten Sekundärfedern auf den Längsträgern 3 auf. Die Sekundärfedern sind, wie allgemein bekannt, zwischen dem Drehgestell und dem Wagenkasten (nicht dargestellt) angeordnet.In the areas provided with the reference numeral 9, the secondary springs, also not shown, rest on the longitudinal members 3. The secondary springs are, as is well known, arranged between the bogie and the car body (not shown).

Wie aus Figur 1 ersichtlich, weisen die Querträger 5 an ihren Enden jeweils eine Kröpfung 11 auf.How out FIG. 1 can be seen, the cross member 5 at their ends in each case a crank 11.

Die Querträger 5 sind so gekröpft, dass die Kröpfung 11 in einer Ebene liegt, die parallel zu den Längsachsen der Längsträger 3 und parallel zu den nicht dargestellten Schienen verläuft.The cross member 5 are cranked so that the crank 11 lies in a plane which is parallel to the longitudinal axes of the longitudinal members 3 and parallel to the rails, not shown.

Durch die Kröpfungen 11 wird der Abstand zwischen den Befestigungspunkten 7 der Primärfedern (nicht dargestellt) und dem Ort, an dem die Querträger 5 mit den Längsträgern 3 verbunden sind, vergrößert. Dies erlaubt die Verwendung größerer Räder (nicht dargestellt) oder zusätzlicher Bremseinrichtungen. Gleichzeitig ist der in einem Bereich 13, der von den Längsträgern 3 und den Querträgern 5 begrenzt wird, verfügbare Bauraum vergrößert.By the cranks 11, the distance between the attachment points 7 of the primary springs (not shown) and the location at which the cross member 5 are connected to the side rails 3, increased. This allows the use of larger wheels (not shown) or additional braking devices. At the same time the space available in a region 13 which is bounded by the longitudinal members 3 and the cross members 5, increased.

Dies bedeutet, dass durch die erfindungsgemäß gekröpften Querträger 5 einerseits große Räder an den Radsätzen (nicht dargestellt) oder zusätzlicher Bremseinrichtungen verwendet werden können und andererseits der verfügbare Bauraum im Bereich 13 zwischen den Querträgern 5 vergrößert werden kann.This means that, on the one hand, large wheels on the wheelsets (not shown) or additional brake devices can be used by the invention according to the cranked cross member 5 and on the other hand, the available space in the region 13 between the cross members 5 can be increased.

Durch die Kröpfungen 11 der Querträger 5 sind Drehstäbe 15 geführt. Die Drehstäbe 15 ragen seitlich über die Längsträger 3 hinaus und sind außerhalb des Drehgestellrahmens 1 an beiden Enden mit jeweils einem Hebel 17 drehfest verbunden.By the cranks 11 of the cross member 5 torsion bars 15 are guided. The torsion bars 15 protrude laterally beyond the longitudinal members 3 and are rotatably connected outside the bogie frame 1 at both ends, each with a lever 17.

An den Enden der Hebel 17 sind Verbindungsmittel 19 (Pendelstützen) und Stoßdämpfer 21 drehfest befestigt. Die Verbindungsmittel 19 (Pendelstützen) der Drehstäbe 15 sind an einem Wagenkasten (nicht dargestellt) gelenkig befestigt. Dadurch werden Wankbewegungen dieses Wagenkastens unterdrückt.At the ends of the lever 17 connecting means 19 (pendulum supports) and shock absorbers 21 are rotatably attached. The connecting means 19 (pendulum supports) of the torsion bars 15 are articulated to a car body (not shown). As a result, rolling movements of this car body are suppressed.

Da es sich bei dem in Figur 1 dargestellten Drehgestellrahmen um den Rahmen eines Jakobs-Drehgestells handelt, auf dem die Enden zweier Wagenkästen aufliegen, sind auch zwei Drehstäbe 15 mit insgesamt vier Hebeln und vier Verbindungsmitteln 19 vorgesehen, wobei jeweils ein Paar von Verbindungsmitteln 19 mit einem Wagenkasten (nicht dargestellt) verbunden ist.Since it is the in FIG. 1 shown bogie frame is about the frame of a Jakobs bogie, on which rest the ends of two car bodies, two torsion bars 15 are provided with a total of four levers and four connecting means 19, wherein in each case a pair of connecting means 19 with a car body (not shown) is connected ,

Falls die erfindungsgemäß gekröpften Querträger 5 bei einem herkömmlichen Drehgestell eingesetzt werden, ist es in der Regel ausreichend, einen Drehstab 15, zwei Hebel 17 und zwei Verbindungsmittel 19 vorzusehen, um den auf dem Drehgestell aufliegenden Wagenkasten zu stabilisieren.If the invention according to the cranked cross member 5 are used in a conventional bogie, it is usually sufficient to provide a torsion bar 15, two levers 17 and two connecting means 19 to stabilize the resting on the bogie car body.

In dem in Figur 1 dargestellten Ausführungsbeispiel sind die Verbindungsmittel 19 in ihrer Länge nicht verstellbar, so dass die Drehstäbe 15 als reine Wankhilfe ausgebildet sind.In the in FIG. 1 illustrated embodiment, the connecting means 19 are not adjustable in their length, so that the torsion bars 15 are designed as pure roll support.

Wenn einer oder mehrere der Verbindungsmittel 19 durch einen längenverstellbaren Aktuator, wie beispielsweise einen doppelt wirkenden Hydraulikzylinder, ersetzt werden, kann durch geeignete Ansteuerung dieses längenverstellbaren Aktuators gezielt eine Neigung des Wagenkastens eingestellt werden. Diese Neigung des Wagenkastens kann beispielsweise beim schnellen Durchfahren von Kurven eingesetzt werden, um die auf die Passagiere wirkenden Fliehkräfte mindestens teilweise zu kompensieren.If one or more of the connecting means 19 are replaced by an adjustable-length actuator, such as a double-acting hydraulic cylinder, a tilt of the car body can be adjusted specifically by suitable control of this length-adjustable actuator. This inclination of the car body can be used, for example, when driving fast curves, at least partially compensate for the forces acting on the passengers centrifugal forces.

In der Mitte der Querträger sind Aufnahmen 23, die der Befestigung von Antriebsmotoren (nicht dargestellt) dienen, vorgesehen. In der Mitte des in Figur 1 rechts angeordneten Querträgers 5 ist des Weiteren eine Längslenkeraufnahme 25 vorgesehen. Diese Längslenkeraufnahme 25 dient dazu, einen Längslenker (nicht dargestellt) an dem Drehgestell zu befestigen, der an seinem anderen Ende mit einem der Wagenkästen verbunden ist. Über diesen Längslenker werden Zug- und Druckkräfte zwischen dem Drehgestell und den Wagenkästen übertragen, so dass die Sekundärfedern 9 von diesen Kräften entlastet werden.In the middle of the cross member receptacles 23, which serve for the attachment of drive motors (not shown) provided. In the middle of in FIG. 1 on the right-hand side crossmember 5, a trailing arm receiver 25 is furthermore provided. This trailing arm receiver 25 is used to attach a trailing arm (not shown) to the bogie, which is connected at its other end to one of the car bodies. About this trailing arm tensile and compressive forces are transmitted between the bogie and the car bodies, so that the secondary springs 9 are relieved of these forces.

In Figur 2 ist eine isometrische Darstellung eines erfindungsgemäßen Querträgers 5 mit einem durch die Kröpfungen 11 hindurchgeführten Drehstab 15 dargestellt. An den Kröpfungen 11 ist jeweils ein Flansch 27 ausgebildet. Dieser Flansch 27 liegt in zusammengebautem Zustand (siehe Figur 1) des Drehgestellrahmens 1 an der Innenseite der Längsträger 3 an.In FIG. 2 an isometric view of a cross member 5 according to the invention with a guided through the cranks 11 torsion bar 15 is shown. At the cranks 11 each have a flange 27 is formed. This flange 27 is in the assembled state (see FIG. 1 ) of the bogie frame 1 on the inside of the side members 3.

Wie aus den Figuren 1 und 2 ersichtlich, wird der Drehstab 15 durch die Längslenkeraufnahme 25 hindurchgeführt.Like from the FIGS. 1 and 2 can be seen, the torsion bar 15 is passed through the trailing arm receiver 25.

Figur 3 zeigt einen Längsschnitt durch einen erfindungsgemäßen Querträger 5 mit eingelegtem Drehstab 15. An den Enden des Drehstabs 15 ist eine Verzahnung 29 ausgebildet. Die Verzahnung 29 dient dazu, die Hebel 17 (siehe Figur 1) drehfest mit dem Drehstab 15 zu verbinden. FIG. 3 shows a longitudinal section through a cross member 5 according to the invention with inserted torsion bar 15. At the ends of the torsion bar 15, a toothing 29 is formed. The toothing 29 serves the lever 17 (see FIG. 1 ) rotatably connected to the torsion bar 15.

Die Lagerung des Drehstabs 15 ist in Figur 3 nicht explizit dargestellt. Es ist jedoch bei diesem Ausführungsbeispiel vorgesehen, die Lagerung in den Endbereichen 31 des Querträgers 5 vorzunehmen. Alternativ wäre es auch möglich, den Drehstab 15 direkt in den Längsträgern 3 oder in einem separaten Lagerbock (nicht dargestellt) zu lagern. Diese Lagerböcke können entweder an den Querträgern 5 oder an den Längsträgern 3 befestigt werden.The storage of the torsion bar 15 is in FIG. 3 not explicitly shown. However, it is provided in this embodiment, make the storage in the end portions 31 of the cross member 5. Alternatively, it would also be possible to mount the torsion bar 15 directly in the longitudinal members 3 or in a separate bearing block (not shown). These brackets can be attached either to the cross members 5 or to the longitudinal members 3.

In Figur 4 ist eine isometrische Darstellung eines erfindungsgemäßen Drehgestells dargestellt, wobei im Gegensatz zu der Darstellung gemäß Figur 1 die Radsätze 33, die Antriebsmotoren 35 und die Sekundärfedern 37 dargestellt sind.In FIG. 4 an isometric view of a bogie according to the invention is shown, wherein in contrast to the illustration according to FIG. 1 the wheelsets 33, the drive motors 35 and the secondary springs 37 are shown.
