Drehgestellrahmen Technisches Gebiet Bogie frame Technical area
Die Erfindung betrifft einen Drehgestellrahmen für ein Schienenfahrzeug, umfassend zwei Längsträger und zumindest einen Querträger. The invention relates to a bogie frame for a rail vehicle, comprising two longitudinal members and at least one cross member.
Die Erfindung ist sowohl auf Drehstellrahmen mit The invention is both on Drehstellrahmen with
innengelagertem Drehgestell, wo also im montierten Zustand die Räder des Schienenfahrzeugs außerhalb der Längsträger angeordnet sind, als auch auf außengelagerte Drehgestelle anwendbar. internally mounted bogie, ie where the wheels of the rail vehicle are arranged outside the side members in the mounted state, as well as applicable to externally mounted bogies.
Stand der Technik Die Kräfteübertragung in einem Drehgestell zwischen den verschiedenen Funktionseinheiten, wie Antrieb oder Bremse, übernimmt der Drehgestellrahmen. Speziell bei Drehgestellen für Hochgeschwindigkeitszüge ist eine hohe Längs- und PRIOR ART The transmission of forces in a bogie between the various functional units, such as drive or brake, takes over the bogie frame. Especially for bogies for high speed trains is a high longitudinal and
Diagonalsteifigkeit des Drehgestellrahmens für die Radsätze betriebsnotwendig. Durch die betrieblich bedingte hoheDiagonal stiffness of the bogie frame for the wheelsets operationally necessary. Due to the operational high
Beanspruchung und die nötige Betriebssicherheit wird der Drehgestellrahmen mit hohem Material- und Fertigungsaufwand hergestellt. Daraus ergibt sich neben hohen Kosten in technischer Hinsicht ein hohes Gewicht des Demand and the necessary operational reliability of the bogie frame is manufactured with high material and manufacturing costs. This results in high technical costs as well as high costs
Drehgestellrahmens. Bogie frame.
Um den hohen Beanspruchungen des Drehgestellrahmens gerecht zu werden, wurden bisher zu deren Herstellung Kastenträger verwendet, also geschlossene Hohlträger, die aus miteinander verschweißten Blechen gefertigt sind. Da nach dem In order to meet the high demands of the bogie frame, box girders have hitherto been used to produce them, ie closed hollow girders made of metal sheets welded together. Because after the
Verschließen eines solchen Kastens mit dem Obergurt, ist die Herstellung einer Schweißnahtgegenlage auf der Seite der Schweißnahtwurzel aufgrund fehlender Zugänglichkeit nicht mehr möglich, daher kann die Schweißnaht nicht mit den gleichen Kräften belastet werden wie eine mit Gegenlage hergestellte. In diesem Fall müssen die Blechstärken erhöht werden, um die Schweißnähte in Folge dicker und daher auch kräftiger ausführen zu können. Dadurch erhöhen sich das Gewicht des Drehgestellrahmens und der Fertigungsaufwand weiter . Closing of such a box with the upper flange, the production of a Schweißnahtgegenlage on the side of the weld root is not due to lack of accessibility more possible, therefore, the weld can not be charged with the same forces as a counter-produced. In this case, the sheet thicknesses must be increased in order to make the welds in a row thicker and therefore stronger. This further increases the weight of the bogie frame and the manufacturing effort.
Darstellung der Erfindung Presentation of the invention
Es ist daher eine Aufgabe der vorliegenden Erfindung, einen Drehgestellrahmen zur Verfügung zu stellen, welcher gegenüber geschlossenen Hohlträgern weniger Gewicht hat. It is therefore an object of the present invention to provide a bogie frame, which has less weight compared to closed hollow beams.
Diese Aufgabe wird durch einen Drehgestellrahmen mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte This object is achieved by a bogie frame with the features of claim 1. advantageous
Ausgestaltungen der Erfindung sind in den jeweiligen Embodiments of the invention are in the respective
abhängigen Ansprüchen definiert. dependent claims defined.
Dabei ist erfindungsgemäß vorgesehen, dass die Längsträger und zumindest ein Querträger jeweils ausschließlich aus einem offenen Profil gebildet sind. Mit dem Begriff „ausschließlich" werden aus dem Stand der Technik bekannte Längs- oder Querträger, die neben einem geschlossenen Hohlprofil auch ein offenes Profil aufweisen, ausgeschlossen . Da ein offenes Profil gegenüber einem geschlossenen It is provided according to the invention that the longitudinal members and at least one cross member are each formed exclusively of an open profile. The term "exclusively" excludes longitudinal or transverse supports which are known from the prior art and which, in addition to a closed hollow profile, also have an open profile
Hohlträger bei gleichen oder sehr ähnlichen Außenmaßen in der Regel weniger Gewicht hat, kann hierdurch das Gewicht des Drehgestellrahmens reduziert werden. Dabei ist das offene Profil - bezogen auf den eingebauten Zustand des  Hollow beam with the same or very similar external dimensions usually has less weight, thereby the weight of the bogie frame can be reduced. Here is the open profile - based on the installed state of
Drehgestellrahmens - in der Regel nach oben, nach unten, oder zu den Seiten geöffnet. Insbesondere kann vorgesehen werden, dass die offenen Profile durch Verschweißen aus mehreren, überwiegend ebenen, Bogie frame - usually up, down, or open to the sides. In particular, it can be provided that the open profiles are welded together by a plurality of, predominantly planar,
Trägerteilen gebildet und die Schweißnähte zwischen den Trägerteilen aufgrund der offenen Breite des Profils mit einer Gegenlage ausgeführt sind. Es wird somit für jede Schweißnaht eine Schweißnahtgegenlage hergestellt, was wiederum hilft, die Blechstärken und damit das Gewicht des Drehgestellrahmens, auf Grund der besseren Carrier parts formed and the welds between the support members are made due to the open width of the profile with a counter-layer. It is thus produced for each weld a Schweißnahtgegenlage, which in turn helps, the plate thickness and thus the weight of the bogie frame, due to the better
Festigkeitsausnutzung des Materials, zu verringern. Strength utilization of the material to reduce.
Neben der einfacheren Fertigung ist die bei In addition to the simpler manufacturing is at
Schienenfahrzeugen betrieblich vorgeschriebene Inspektion einfacher und schneller durchzuführen. Weiters kommt dieser Vorteil auch im Zuge der Hauptrevision zum Tragen, da die übliche teure Bauteilprüfung mit Endoskop und Durchstrahlung durch eine weniger aufwändige Oberflächenrissprüfung ersetzt werden kann. Rail vehicles perform operational inspection easier and faster. Furthermore, this advantage also comes into play in the course of the main revision, since the usual expensive component testing with endoscope and radiography can be replaced by a less complex surface crack inspection.
Wenn das offene Profil durch Weglassen eines Gurtes oder Steges, also eines Deckblechs, eines geschlossenen If the open profile by omitting a belt or web, so a cover plate, a closed
Hohlprofils gebildet wird, fallen sowohl dieses Deckblech als auch die beiden zugehörigen Schweißnähte weg, die  Hollow profile is formed, fall off both this cover plate and the two associated welds, the
verbleibenden maßgeblichen Schweißnähte sind beidseitig zugänglich. Diese können somit durchgängig als Schweißnaht mit Schweißnahtgegenlage hergestellt werden. remaining relevant welds are accessible on both sides. These can thus be made consistently as a weld with Schweißnahtgegenlage.
Eine Ausführungsform des Drehgestellrahmens sieht vor, dass die Längsträger keinen Obergurt, sondern nur einen Untergurt aufweisen, der bzw. die äußeren Querträger keinen Untergurt, sondern nur einen Obergurt aufweisen, wobei die Untergurte der Längsträger starr (also etwa ohne Gelenke) in die An embodiment of the bogie frame provides that the side members have no upper flange, but only a lower flange, the or the outer cross member no lower flange, but only have a top flange, the lower straps of the longitudinal support rigid (ie, approximately without joints) in the
Obergurte des bzw. der mittleren (inneren) Querträger übergehen. Dies könnte grundsätzlich etwa durch Verschweißen der Untergurte der Längsträger mit den Obergurten der Go over the upper straps of the middle (inner) cross member. This could basically be done by welding the lower straps of the side members with the upper straps
Querträger im Bereich der Querträger verwirklicht werden. Cross beams are realized in the region of the cross member.
Eine besonders stabile Ausführung, die besonders für A particularly stable design, especially for
Hochgeschwindigkeitszüge geeignet ist, besteht darin, dass die Untergurte der Längsträger und die Obergurte zumindest eines Querträgers aus einem Teil gefertigt sind. Dabei wird also auf die übliche Trennung von Längs- und Querträger verzichtet, bei denen die Verschweißung von Längs- und High-speed trains is that the lower chords of the side members and the upper chords of at least one cross member are made of one piece. Thus, the usual separation of longitudinal and transverse beams is omitted, in which the welding of longitudinal and
Querträger immer auch eine Schwachstelle darstellt. Durch die einteilige Ausführung kann trotz erheblicher Cross member always represents a weak spot. Due to the one-piece design, despite considerable

Die Stabilität wird noch weiter erhöht, wenn der Untergurt des Längsträgers über die gesamte Länge des Längsträgers durchgezogen ist. The stability is further increased when the lower flange of the longitudinal member is pulled through over the entire length of the longitudinal member.
Eine mögliche Ausführungsform des Übergangs zwischen Längsund Querträger ist, dass der Untergurt der Längsträger auf den Obergurt zumindest eines Querträgers eben übergeht. Dies kann etwa für den oder die Querträger im mittleren Bereich der Längsträger vorgesehen sein, wo die Längsträger nach unten gekröpft sind. One possible embodiment of the transition between the longitudinal and transverse beams is that the lower flange of the longitudinal beams transitions to the upper flange of at least one cross member. This can be provided approximately for the cross member or in the middle region of the longitudinal members, where the longitudinal members are bent down.
