Description

SCHIENENFAHRZEUG  RAIL VEHICLE
Die vorliegende Erfindung betrifft ein Schienenfahrzeug mit einer Mehrzahl von Wagenkästen, wobei ein erster und ein zweiter Wagenkasten auf einer Wiege eines Jakobs-Drehgestelles lagern, wobei die Wagenkästen durch eine sphärische Gelenkeinrichtung miteinander verbunden sind, wobei die sphärische Gelenkeinrichtung auf der Wiege angeordnet ist. The present invention relates to a rail vehicle having a plurality of car bodies, wherein a first and a second car body support on a cradle of a Jacob bogie, wherein the car bodies are interconnected by a spherical hinge means, wherein the spherical hinge means is arranged on the cradle.
Aus dem Stand der Technik sind Schienenfahrzeuge mit Jakobs- Drehgestellen hinreichend bekannt. Am bekanntesten ist hierbei der TGV, wobei zwei Wagenkästen sich im Übergangsbereich auf einem Jakobs- Drehgestell abstützen. Rail vehicles with Jakobs- bogies are well known from the prior art. The best known here is the TGV, with two car bodies supported in the transition area on a Jakobs- bogie.
Ein solches Jakobs-Drehgestell besteht aus einem Rahmen, wobei zu beiden Enden des Rahmens jeweils ein Radsatz durch Primärfedern an dem Rahmen angeordnet ist. Auf dem Rahmen lagert eine sogenannte Wiege, die durch Sekundärfedern auf dem Rahmen abgestützt ist. Auf der Wiege sind die beiden Wagenkästen durch eine sphärische Such a Jakobs bogie consists of a frame, wherein at both ends of the frame in each case a wheel set is arranged by primary springs on the frame. On the frame a so-called cradle supports, which is supported by secondary springs on the frame. On the cradle, the two car bodies are by a spherical
Gelenkeinrichtung abgestützt gelagert. Eine solche sphärische Suspension device supported supported. Such a spherical one
Gelenkeinrichtung für ein Jakobs-Drehgestell ist aus der WO 2005/023619 bekannt. Allerdings sind hierbei sowohl die Nick- als auch die Knick-, Wank- und Versatzbewegungen stark eingeschränkt. Der Grund hierfür ist darin zu finden, dass lediglich der eine Wagenkasten relativ zu dem anderen Wagenkasten beweglich ist. Der andere Wagenkasten ist fest mit der Wiege verbunden, weshalb dieser starr ist. Das bedeutet, dass sowohl Nick- als auch Knick-, Wank- und Versatzbewegungen nur in relativ geringem Umfange zugelassen werden. Die der Erfindung zugrunde liegende Aufgabe besteht demzufolge darin, bei einem Schienenfahrzeug der eingangs genannten Art eine Jointing device for a Jakobs bogie is known from WO 2005/023619. However, in this case both the pitch and the kinking, rolling and offset movements are severely limited. The reason for this is that only one carbody is movable relative to the other carbody. The other car body is firmly connected to the cradle, which is why this is rigid. This means that pitch, roll, and offset movements are tolerated only to a relatively small extent. The object underlying the invention is therefore, in a rail vehicle of the type mentioned a
Gelenkeinrichtung für ein Jakobs-Drehgestell bereitzustellen, wobei die Gelenkeinrichtung in der Lage ist, sämtliche beim Fahren auftretende  To provide a hinge device for a Jakobs bogie, wherein the hinge device is capable of all occurring when driving
5 Bewegungen auch mit größeren Winkeln zu kompensieren bzw. 5 movements even with larger angles to compensate or
aufzunehmen, insbesondere als da sind, Nick-, Wank- und  especially as there are, pitch, roll and
Knickbewegungen sowie Versatzbewegungen, wie sie auftreten, wenn solche Fahrzeuge über Weichen fahren. o Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass die Gelenkeinrichtung mindestens zwei sphärische Gelenklager aufweist. Hierbei ist insbesondere vorgesehen, dass die beiden Gelenklager in einer Ebene zueinander angeordnet sind, was ein platzsparende Bauweise mit sich bringt, sodass der Abstand zwischen den Wagenkästen, also die5 Länge des Übergangs zwischen den beiden Fahrzeugen, kurz gewählt werden kann, aber dennoch z. B. erhebliche Knickbewegungen zugelassen werden.  Kinking movements and offsets, as they occur when such vehicles drive over switches. o To solve the problem, the invention proposes that the joint device has at least two spherical spherical plain bearings. In this case, it is particularly provided that the two pivot bearings are arranged in a plane to each other, which brings a space-saving design with it, so that the distance between the car bodies, so die5 length of the transition between the two vehicles, can be selected short, but still z. B. significant buckling movements are allowed.
Eine erste Variante einer derartigen erfindungsgemäßen sphärischeno Gelenkeinrichtung mit zwei sphärischen Gelenklagern zeichnet sich A first variant of such a spherical joint device according to the invention with two spherical plain bearings is distinguished

Hierzu ist im Einzelnen vorgesehen, dass zur Bildung der beiden Gelenklager mit einem solchen gemeinsamen Drehpunkt zwei ineinander oder aufeinander gelagerte Kugelsegmente5 vorgesehen sind, wobei das äußere Kugelsegment durch eine  common pivot point. For this purpose, it is provided in detail that for the formation of the two joint bearings with such a common pivot point two nested or superimposed Kugelsegmente5 are provided, wherein the outer spherical segment by a

Das äußere Kugelsegment zeigt einen Sattel zur Verbindung mit dem einen ersten Wagenkasten, wobei die Lagerschale mit dem anderen zweiten Wagenkasten in Verbindung steht. Somit steht jedes der beiden Gelenklager mit einem Wagenkasten in Verbindung. Connecting link to the cradle of the Jacob bogie has. Daso link also has a support leg for connection to the cradle. The outer ball segment shows a saddle to Connection with the one first car body, wherein the bearing shell is in communication with the other second car body. Thus, each of the two pivot bearings is connected to a car body.
Wie bereits an anderer Stelle ausgeführt, ist das oben beschriebene doppeltsphärische Lager in der Lage im Wesentlichen sämtliche beim Fahren auftretenden Bewegungen, wie Wank-, Nick-, Dreh- (Knick-) und Versatzbewegungen sowie auch Kombinationen hieraus aufzunehmen, und zwar mit verhältnismäßig großen Winkeln; allerdings hat diese Konstruktion den Nachteil, dass die Wiege nicht unter allen Umständen momentenfrei ist. Solche Momente entstehen insbesondere dann, wenn auf die As already stated elsewhere, the double-spherical bearing described above is able to absorb substantially all movements occurring during driving, such as rolling, pitching, turning (buckling) and offset movements, as well as combinations thereof, and with relatively large movements angles; However, this construction has the disadvantage that the cradle is not torque-free under all circumstances. Such moments arise especially when on the
erfindungsgemäße doppeltsphärische Gelenkeinrichtung, deren Drehpunkt zur Oberfläche der Wiege beabstandet ist, Kräfte in Richtung der Double-spherical joint device according to the invention, whose fulcrum is spaced from the surface of the cradle, forces in the direction of
Fahrzeuglängsachse oder der Fahrzeugquerachse einwirken. Kräfte, die in Richtung der Fahrzeuglängsachse in Höhe des Drehpunktes auf die Vehicle longitudinal axis or the vehicle transverse axis act. Forces acting in the direction of the vehicle longitudinal axis at the level of the pivot point on the
Gelenkeinrichtung einwirken, sind schlussendlich solche, die beim Acting joint device, are ultimately those that
Beschleunigen und Bremsen der Fahrzeuge entstehen. Querkräfte, also Kräfte quer zur Längsachse des Fahrzeugs, entstehen durch Fliehkräfte oder sogenannte Spurführungskräfte. Längs- als auch Querkräfte sind daher Horizontalkräfte. Die Momente hieraus müssen unmittelbar von der Wiege aufgenommen werden. Durch die Federn, mit denen die Wiege auf dem Rahmen des Jakobs-Drehgestells lagert, werden die Reaktionskräfte aufgrund solcher Momente auf den Rahmen des Jakobs-Drehgestells übertragen. Um dies zu vermeiden, können Längs- und Querlenker, z. B. Lemniskaten-Lenker, zwischen der Wiege und dem Rahmen des Jakobs- Drehgestells vorgesehen sein, um ein Einfedern der Wiege auf dem Acceleration and braking of the vehicles arise. Transverse forces, ie forces transverse to the longitudinal axis of the vehicle, arise from centrifugal forces or so-called tracking forces. Longitudinal and lateral forces are therefore horizontal forces. The moments from here must be taken directly from the cradle. The springs supporting the cradle on the frame of the Jakob bogie cause the reaction forces to be transmitted to the frame of the Jakob bogie due to such moments. To avoid this, longitudinal and transverse links, z. B. lemniscate handlebar, between the cradle and the frame of the Jakobs- bogie be provided to a compression of the cradle on the
Rahmen zu vermeiden. Das heißt, dass durch die horizontal angreifenden Kräfte im Wesentlichen keine Reaktionskräfte auf die Federn, mit der die Wiege auf dem Rahmen gelagert ist, übertragen werden sollen. Eine andere Möglichkeit, um die auf den Rahmen des Jakobs-Drehgestells federnd gelagerte Wiege von Momenten aufgrund des Einflusses von Längs- und Querkräften im Wesentlichen freizuhalten, besteht nach einer zweiten Variante der sphärischen Gelenkeinrichtung darin, dass die Frame to avoid. This means that essentially no reaction forces are to be transmitted to the springs with which the cradle is mounted on the frame by the horizontally acting forces. Another possibility for essentially freeing the cradle of moments resiliently mounted on the frame of the Jakob bogie, due to the influence of longitudinal and transverse forces, according to a second variant of the spherical articulation device, is that the
5 sphärische Gelenkeinrichtung mindestens zwei Gelenke in Richtung der Hochachse des Schienenfahrzeugs beabstandet übereinander angeordnet aufweist. Das heißt, es sind zwei sphärische Gelenklager vorgesehen, die insbesondere durch einen Stehbolzen miteinander verbunden sind. Hierbei ist als sphärisches Gelenklager ein oberes Kugelgelenk vorgesehen, dass i o der Verbindung mit den beiden Wagenkästen dient, wobei das untere  Spherical joint means spaced at least two joints in the direction of the vertical axis of the rail vehicle has arranged one above the other. That is, there are provided two spherical spherical plain bearings, which are connected in particular by a stud. Here, as spherical spherical plain bearing an upper ball joint is provided that i o the connection with the two car bodies is used, the lower
Kugelgelenk in Verbindung mit der Wiege des Jakobs-Drehgestells steht. Im Einzelnen weist die Wiege zur Aufnahme des unteren Kugelgelenks einen Topf auf, in dem das untere Kugelgelenk als sphärisches Lager gelagert ist. Die Lagerung erfolgt hierbei derart, dass das untere sphärische Ball joint in conjunction with the cradle of the Jacob bogie is. In detail, the cradle for receiving the lower ball joint on a pot in which the lower ball joint is mounted as a spherical bearing. The storage takes place in such a way that the lower spherical
15 Gelenklager relativ zum Topf schwenk- bzw. drehbeweglich ist. Dadurch, dass das untere sphärische Lager schwenkgelenkig relativ zu dem Topf in dem Topf angeordnet ist, können Längs- und Querkräfte, die in das obere sphärische Lager durch die Wagenkästen eingebracht werden und die aufgrund des durch den Stehbolzen zwischen den beiden sphärischen15 pivot bearing is pivotable relative to the pot or rotatable. Characterized in that the lower spherical bearing is pivotally mounted relative to the pot in the pot, longitudinal and transverse forces, which are introduced into the upper spherical bearing by the car bodies and due to the through the stud between the two spherical
0 Gelenklagern erzeugten Hebelarms und an sich Momente in die Wiege einleiten würden, im Wesentlichen abgefangen werden. Das heißt, dass die Wiege durch eine Gelenkeinrichtung mit beabstandet übereinander angeordneten sphärischen Gelenklagern, bei der das untere Lager schwenkbeweglich auf der Wiege des Jakobs-Drehgestells gelagert ist, im5 Wesentlichen momentenfrei ist.  0 spherical bearings produced lever arm and in itself would initiate moments in the cradle are essentially intercepted. That is, the cradle is substantially torque-free by a hinge having spaced superimposed spherical plain bearings in which the lower bearing is pivotably supported on the cradle of the Jacob bogie.
Vorteilhaft ist in diesem Zusammenhang, wenn die beiden übereinander angeordneten Gelenklager so eingebaut sind, dass sie in Richtung der Aufsattellast und der Stützkraft, die jeweils größte Fläche bereitstellen, also0 die geringsten Flächenpressung aufweisen. Insofern sind die beiden It is advantageous in this context, when the two superimposed joint bearings are installed so that they have in the direction of Aufsattellast and the supporting force, each provide the largest area, so0 have the lowest surface pressure. In that sense, the two are
