A boggie frame for railway vehicles preferably comprising four wheels, which are rotatably mounted in an unsprung manner on frame sides (3) which are hinge-connected with one another, characterized in that each of the two frame sides (3) comprises an outrigger arm (4) which on the one hand is rigidly connected to the frame side and on the other hand - in order to form a pivoting axis (6) arranged exactly in the transverse direction of the boggie - is hinge-mounted in the longitudinal centre of the respective second frame side (3).

Description

Die Erfindung betrifft einen Fahrwerksrahmen für Schienenfahrzeuge mit vorzugsweise vier Rädem, die an gelenkig miteinander verbundenen Rahmenwangen drehbar gelagert sind.The invention relates to a chassis frame for rail vehicles with preferably four wheels, which are rotatably mounted on articulated frame cheeks.

Ein Fahrwerk mit vier Rädern ist statisch nicht bestimmt, so daß sich irgendwelche Radlasten an den Rädern einstellen können. Wegen der gleichmäßigen Schienenbeanspruchung und wegen der Sicherheit der Spurführung sind jedoch gleiche Radlasten an alle Rädern auch bei sehr schlechter Geislage erwünscht.A chassis with four wheels is not statically determined, so that any wheel loads can arise on the wheels. Because of the even load on the rails and the safety of the guidance, the same wheel loads on all wheels are desirable, even in very poor geis conditions.

Es ist bekannt, daß zur Erfüllung dieser Aufgabe zwei Wege beschritten werden. In konventionellen Drehgestellen werden die Radsätze an den Radsatzlagem federnd im Drehgestellrahmen gelagert. Die Federn gestatten, daß die Räder gegen die Federkräfte vertikalen Schienenlagefehlern folgen können und so annährend gleiche Radlasten an allen Rädern entstehen.It is known that there are two ways to accomplish this task. In conventional bogies, the wheelsets are spring-mounted to the wheelset bearings in the bogie frame. The springs allow the wheels to follow vertical rail position errors against the spring forces and thus approximately equal wheel loads occur on all wheels.

Der andere Weg sieht Gelenkrahmen vor, bei denen der Fahrwerksrahmen mehrteilig ausgebildet ist. Zwei Varianten sind gebräuchlich:

  • Gemäß US-A 3 313 245 werden zwei Rahmenhälften in diagonal zur Rahmenlängsachse angeordneten Gelenken miteinander verbunden. An vertikalen Schienenlagefehlern kann der Rahmen um die durch die Gelenkpunkte verlaufende Drehachse Bewegungen ausführen und jeweils ein Rad dem Schienenlagefehler folgen. Da die Drehachse diagonal zur Rahmenlängsachse verläuft, ist mit der Vertikalbewegung eines Rades zwangsläufig ein Sturz der Radebene und eine Schrägstellung der Radebene zur Fahrtrichtung verbunden. Beide Bewegungen sind für die Spurführung unerwünscht, da sie für die Spurführung schädliche Kräfte im Radaufstandspunkt hervorrufen.
The other way provides articulated frames in which the chassis frame is made up of several parts. Two variants are used:
  • According to US Pat. No. 3,313,245, two frame halves are connected to one another in joints arranged diagonally to the longitudinal axis of the frame. On vertical rail position errors, the frame can move around the axis of rotation running through the articulation points and one wheel can follow the rail position error. Since the axis of rotation runs diagonally to the longitudinal axis of the frame, the vertical movement of a wheel inevitably involves a camber of the wheel plane and an inclined position of the wheel plane in relation to the direction of travel. Both movements are undesirable for the guidance since they cause harmful forces in the wheel contact point for the guidance.

Die andere, beispielsweise durch die GB-A 991 619 oder die EP-A 0 071 575 bekannte Variante vermeidet dieser Fehler. Eine der beiden Rahmenwangen wird drehbar an dem Querträger des Drehgestells gelagert, der fest mit der anderen Rahmenwange verbunden ist. An vertikalen Schienenlagefehlern können die Räder vertikal ausweichen, ohne daß sich Sturz und Schräglauf ändern. Nachteilig ist, daß die Lagerstelle, die die Rahmenwange mit dem Querträger verbindet, sehr stabil ausgebildet werden muß, da sie die an die Räder angreifenden Kräfte als Momente abstützen muß. Die Konstruktion wird dadurch aufwendig und schwer.The other variant, known for example from GB-A 991 619 or EP-A 0 071 575, avoids this error. One of the two frame cheeks is rotatably mounted on the cross member of the bogie, which is firmly connected to the other frame cheek. In the case of vertical rail position errors, the wheels can dodge vertically without changing camber and skew. The disadvantage is that the bearing point, which connects the frame cheek to the cross member, must be made very stable, since it must support the forces acting on the wheels as moments. This makes the construction complex and heavy.

Der Erfindung liegt die Aufgabe zugrunde, einen Fahrwerksrahmen zu ermöglichen, der einfach und leicht zu bauen ist, gleiche Radlasten an allen Rädem sicherstellt und an Schienenlagefehlern keine Sturz- und Schräglaufänderungen erzeugt.The invention has for its object to enable a chassis frame that is simple and easy to build, ensures equal wheel loads on all wheels and no camber and skew changes in rail position errors.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jede der beiden Rahmenwangen einen einerseits mit ihr fest verbundenen und andererseits - zum Bilden einer exakt in Querrichtung des Fahrwerkes angeordneten Schwenkachse - in Längsmitte der jeweils anderen Rahmenwange gelenkig gelagerten Auslegerarm aufweist.This object is achieved in that each of the two frame cheeks has a cantilever arm which is firmly connected to it on the one hand and on the other hand - to form a swivel axis arranged exactly in the transverse direction of the chassis - in the longitudinal center of the other frame cheek.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere in folgendem:

  • Die im Rad/Schiene-Kontakt entstehenden Seitenkräfte erzeugen ein Moment um die Hochachse eines Gelenklagers. Wegen des großen Abstandes der beiden Gelenklager entsteht eine nur geringe Reaktionskraft, die vom anderen Gelenklager aufgenommen wird. Die Lage der Gelenke in der Mitte der Rahmenwangen gewährleistet gleichzeitig eine sturz- und schräglauffreie Vertikalbewegung jedes einzelnen Fahrwerksrades. Sie gewährleistet au-Berdem eine schubsteife Rahmenkonstruktion, ohne daß die Gelenklager besonders groß und schwer dimensioniert werden müssen.
The advantages that can be achieved with the invention are in particular:
  • The side forces generated in the wheel / rail contact generate a moment about the vertical axis of a spherical plain bearing. Because of the large distance between the two spherical bearings, there is only a small reaction force which is absorbed by the other spherical bearing. The position of the joints in the middle of the frame cheeks ensures that each individual landing gear wheel moves vertically without camber and skewing. It also ensures a shear-resistant frame construction without the spherical bearings having to be particularly large and heavy.

Ausführungsbeispiele der Erfindung sind in der Zeichnung schematisch dargestellt und werden im folgenden näher beschrieben. Es zeigen

  • Figur 1 das Prinzip des Fahrwerksrahmens, in Draufsicht,
  • Figur 2 eine besonders zweckmäßige Ausführungsform für Einzelradfahrwerke, ebenfalls in Draufsicht.
Embodiments of the invention are shown schematically in the drawing and are described in more detail below. Show it
  • 1 shows the principle of the chassis frame, in plan view,
  • Figure 2 shows a particularly useful embodiment for single wheel chassis, also in plan view.

Dargestellt sind in Fig. 1 die Radsätze 1, die mit den Radsatzlagern 2 in den Rahmenwangen 3 des Fahrwerksrahmens drehbar gelagert sind. Fest mit den jeweiligen Rahmenwangen 3 verbunden sind Auslegerarme 4, an deren Enden sich Gelenklager 5 befinden, die in den Rahmenwangen 3 gelagert sind. Dadurch kann jede Rahmenwange 3 für sich und unabhängig von der anderen Drehbewegungen um die gemeinsame Schwenkachse 6 ausführen.Shown in Fig. 1 are the wheelsets 1, which are rotatably mounted with the wheelset bearings 2 in the frame cheeks 3 of the chassis frame. Cantilever arms 4 are fixedly connected to the respective frame cheeks 3, at the ends of which there are articulated bearings 5 which are mounted in the frame cheeks 3. This allows each frame cheek 3 to perform independently of the other rotary movements about the common pivot axis 6.

In einer anderen Ausgestaltung der Erfindung nach Fig. 2, die besonders für radsatzlose Fahrwerke geeignet ist, werden die Räder 1 auf Achsschenkeln 2, die mit den Rahmenwangen 3 verbunden sind, gelagert. Die Auslegerarme 4 sind aufgegliedert. Sie schließen in der Nähe der Achsschenkel 2 an die Rahmenwangen 3 an und geben dem Verband eine hohe Steifigkeit bei geringem Gewicht. An den Enden der Auslegerarme 4 befinden sich Gelenklager 5, die in den Rahmenwangen 3 gelagert sind. Jedes Rahmenteil, bestehend aus Rahmenwangen 3 und Auslegerarmen 4, kann wiederum für sich und unabhängig vom anderen Bewegungen um die gemeinsame Schwenkachse 6 ausführen und so den idealen Radlastausgleich sicherstellen.In another embodiment of the invention according to FIG. 2, which is particularly suitable for gearless chassis, the wheels 1 are mounted on steering knuckles 2, which are connected to the frame cheeks 3. The boom arms 4 are broken down. They connect to the frame cheeks 3 in the vicinity of the steering knuckle 2 and give the dressing high rigidity with low weight. At the ends of the cantilever arms 4 there are spherical bearings 5 which are mounted in the frame cheeks 3. Each frame part, consisting of frame cheeks 3 and cantilever arms 4, can in turn perform independently of the other movements about the common pivot axis 6 and thus ensure the ideal wheel load compensation.
