Description

Beschreibung description

Fahrwerkrahmen für Schienenfahrzeuge. Die Erfindung betrifft einen Fahrwerkrahmen für Chassis frame for rail vehicles. The invention relates to a chassis frame for

Schienenfahrzeuge, wobei der Fahrwerkrahmen zwei Längsträger und zumindest einen zwischen diesen angeordneten Querträger aufweist, der gelenkig mit den Längsträgern verbundenen ist. Mit der gelenkigen Verbindung von Längs- und Querträger eines Fahrwerkrahmens kann ein gegenüber starren Fahrwerksrahmen verbessertes Entgleisungsrisiko erzielt werden.  Railway vehicles, wherein the chassis frame has two longitudinal members and at least one arranged between them cross member which is pivotally connected to the longitudinal members. With the articulated connection of the longitudinal and transverse beams of a chassis frame, an improved risk of derailment compared to rigid chassis frame can be achieved.

Ein derartiges Fahrwerk mit einem H-förmigen, verwindbaren Rahmen, bestehend aus zwei Längs-und einem Querträger, wird in der DE 43 06 848 Al und in der EP 0 409 128 AI Such a chassis with an H-shaped, twistable frame consisting of two longitudinal and a cross member, in DE 43 06 848 Al and in EP 0 409 128 AI

beschrieben. Die Einleitung von Querkräften in den described. The introduction of shear forces in the

Fahrwerkrahmen erfolgt hierbei über Radsatzlager, die mit den Längsträgern starr verbunden sind. Chassis frame takes place here via wheelset bearings which are rigidly connected to the longitudinal members.

Die WO 90/11216 offenbart ein Fahrwerk mit gelenkigem Rahmen mit zumindest einem zwischen zwei Längsträgern angeordneten Querträger, der gegen die Längsträger abgefedert ist. Auch hier erfolgt die Einleitung auftretender Querkräfte, die durch Lenkvorgänge verursacht werden können, über starr mit den Längsträgern verbundene Radsatzlager. WO 90/11216 discloses a chassis with an articulated frame with at least one arranged between two longitudinal members cross member, which is cushioned against the side members. Again, the initiation occurring lateral forces that can be caused by steering operations, via rigidly connected to the longitudinal members axle box.

Bei den soeben genannten Fahrwerken erfolgt die Einleitung von Querkräften, wie sie beispielsweise bei Kurvenfahrten auftreten können, in den Fahrwerkrahmen über Radsatzlager, die mit den Längsträgern des Fahrwerkrahmens verbunden sind, wobei der Fahrwerkrahmen bezüglich dieser Querkräfte In the just mentioned suspensions, the introduction of lateral forces, as may occur, for example when cornering, takes place in the chassis frame via wheelset bearings which are connected to the longitudinal members of the chassis frame, wherein the chassis frame with respect to these transverse forces

möglichst verwindungssteif sein sollte, um einen stabilen Lauf sicher zu stellen. should be as rigid as possible to ensure a stable run.

Nachteilig an diesen Ausführungsformen ist, dass mit ihnen die erwünschte Querkraftsteifigkeit zwischen den Radsätzen nicht erreicht werden kann. Aus der EP 1276653 Bl ist ein verwindungssteifer Fahrwerkrahmen bekannt, bei dem die Radsatzlager mit dem bzw. jeweils einem der Querträger des Schienenfahrzeuges verbunden sind. A disadvantage of these embodiments is that with them the desired lateral force stiffness between the wheelsets can not be achieved. From EP 1276653 Bl a torsion-resistant chassis frame is known, in which the wheelset bearings are connected to the or each one of the cross member of the rail vehicle.

Damit erfolgt die Einleitung der auftretenden Querkräfte über die Radsatzlager direkt in den jeweiligen Querträger. Da der Querträger gegenüber den auftretenden Querbelastungen eine wesentlich höhere Schubsteifigkeit aufweist als die Thus, the initiation of the occurring shear forces on the wheelset directly into the respective cross member. Since the cross member with respect to the transverse loads occurring has a much higher shear stiffness than the

Längsträger, werden dadurch die Steifigkeitseigenschaften des Fahrwerkes und damit der stabile Lauf wesentlich verbessert. Side members, thereby the rigidity properties of the chassis and thus the stable running are significantly improved.

Der Erfindung liegt die Aufgabe zugrunde, diesen bekannten Fahrwerkrahmen weiterzuentwickeln . The invention has for its object to further develop this known chassis frame.

Erfindungsgemäß geschieht dies mit einem Fahrwerkrahmen der eingangs genannten Art, bei dem die Längsträger gebogen ausgeführt sind und durch eine entsprechende Ausnehmung des Querträgers hindurchragen. According to the invention, this is done with a chassis frame of the type mentioned, in which the longitudinal members are designed bent and protrude through a corresponding recess of the cross member.

Damit können wesentliche bauliche Einschränkungen bei aus dem Stand der Technik bekannten Fahrwerkrahmen überwunden werden. This allows substantial structural limitations to be overcome in known from the prior art chassis frame.

So sind bei dem aus der EP 1276653 Bl bekannten Fahrwerkrahmen die beiden Längsträger über dem Querträger und zusätzlich über den Primärfedern angeordnet, damit die Primärfedern kein Torsionsmoment in den Längsträger einleiten. Damit ist der seitliche Abstand der beiden Längsträger zueinander durch die Spurweite festgelegt. Thus, in the chassis frame known from EP 1276653 Bl, the two longitudinal members are arranged above the cross member and additionally via the primary springs, so that the primary springs do not introduce any torsional moment into the longitudinal member. Thus, the lateral distance of the two longitudinal members to each other is determined by the track.

An der Fahrzeugaußenseite ist bei dem bekannten Fahrwerkrahmen neben dem Längsträger auf dem Querträger die Sekundärfeder angeordnet. Somit ist der maximale Bauraum für die Sekundärfeder in seitlicher Richtung durch den Längsträger nach innen und das gegebene Fahrzeugumgrenzungsprofil nach außen hin begrenzt. Bei der Ausdrehung des Fahrwerks relativ zum Wagenkasten in Bogenradien muss die Sekundärfeder einen entsprechenden Lateralweg vollführen können. Mit zunehmendem Lateralweg steigt der Durchmesser der Sekundärfeder. On the vehicle outside, the secondary spring is arranged in the known chassis frame next to the longitudinal member on the cross member. Thus, the maximum space for the secondary spring in the lateral direction by the longitudinal member inwards and the given Fahrzeugumgrenzungsprofil is limited to the outside. When the landing gear is turned relative to the car body in arc radii, the secondary spring must be able to perform a corresponding lateral travel. As the lateral path increases, the diameter of the secondary spring increases.

Bei engen Lichtraumprofilen (gegebenenfalls in Kombination mit kleinen Bogenradien) ist der oben beschriebene Bauraum nicht mehr ausreichend, eine geeignete Sekundärfeder mit entsprechend großem Durchmesser zu verbauen. For narrow clearance clearances (possibly in combination with small radii of curvature) of the space described above is no longer sufficient to install a suitable secondary spring with a correspondingly large diameter.

Bei der erfindungsgemäßen Lösung ist hingegen die Position der auf dem Querträger sitzenden Sekundärfedern seitlich variabel. Die Sekundärfedern können insbesondere auch teilweise oder ganz über dem Längsträger angeordnet sein. In the solution according to the invention, however, the position of the seated on the cross member secondary springs is laterally variable. The secondary springs may in particular also be arranged partially or completely over the longitudinal member.

Vorteilhaft ist es weiterhin, wenn die Verbindungselemente zwischen Längs- und Querträger als weitere Federstufe It is also advantageous if the connecting elements between the longitudinal and transverse beams as a further spring stage

ausgeführt sind. are executed.

Eine weitere vorteilhafte Ausführungsform erhält man, wenn die Verbindungselemente zwischen Längs- und Querträger so ausgeführt sind, dass sie Antriebs-, oder Bremsmomente aufnehmen und den Nickwinkel der Fahrmotoren und des Querträgers begrenzen können. A further advantageous embodiment is obtained when the connecting elements between the longitudinal and transverse beams are designed so that they receive drive or braking torques and can limit the pitch angle of the traction motors and the cross member.

Der in den Fig. lund 2 schematisch dargestellte Fahrwerkrahmen umfasst zwei Längsträger 1 und einen Querträger 2. Die beiden Längsträger sind gebogen ausgeführt und durchdringen den Querträger in einer dafür vorgesehenen Ausnehmung. Über Verbindungselemente 4 liegt der Querträger 2 auf den The chassis frame shown schematically in FIGS. Lund 2 comprises two longitudinal members 1 and a cross member 2.

beispielsweise bei Kurvenfahrten an die Gleisverwindung ausrichten können, wodurch das Entgleisungsrisiko gegenüber starren Fahrwerkrahmen verringert werden kann. For example, when cornering can align to the track warp, whereby the risk of derailment over rigid chassis frame can be reduced.

Die erfindungsgemäße Ausführung gibt nun in Bezug auf die Anordnung und die Auslegung der Sekundärfeder 3 erheblichen Freiraum. So kann diese Feder beispielsweise auch über den Längsträgern 1 angeordnet sein. Damit kann die Biegebelastung für die Querträger durch die Sekundärfedern reduziert werden. The inventive design is now in relation to the arrangement and the design of the secondary spring 3 considerable freedom. For example, this spring can also be used over the Longitudinal beams 1 may be arranged. Thus, the bending load for the cross member can be reduced by the secondary springs.

In dem in Fig. 1 und Fig. 2 dargestellten Ausführungsbeispiel ist der Querträger 2 als Rahmen mit Verstrebungen ausgeführt. Damit kann das Gewicht dieses Querträgers 2 gering gehalten werden . In the embodiment shown in Fig. 1 and Fig. 2, the cross member 2 is designed as a frame with braces. Thus, the weight of this cross member 2 can be kept low.

In this case, the cross member 2 is constructed from a cross member frame 5, which also has provided for receiving the side members 1 recesses 6. Inside, this frame is reinforced by a plate.

Vorzugsweise können diese Ausnehmungen 6 pilzförmig gestaltet sein, sodass die Längsträger 1 gegen Abheben gesichert sind. Preferably, these recesses 6 may be designed mushroom-shaped, so that the longitudinal members 1 are secured against lifting.

Diese Sicherung gegen Abheben ist bei einer dritten This backup against lifting is at a third

dargestellt, kann die Auflagefläche 7 in dieser Ausnehmung gewölbt ausgeführt sein, sodass einerseits der notwendige Bewegungsspielraum für den Längsträger 1 gegeben ist und andererseits ein Abheben verhindert wird. Aus Festigkeitsgründen wird, wie in Fig. 7 dargestellt, die Ausnehmung dreieckförmig ausgeführt. shown, the support surface 7 can be curved in this recess, so that on the one hand the necessary range of motion for the side member 1 is given and on the other hand, a lifting is prevented.
