Description
Die Erfindung betrifft ein Fahrwerk für ein Schienenfahrzeug mit zumindest zwei in Radsatzlagern gelagerten Radsätzen mit Achsen, Rädern und einem Fahrwerkrahmen, wobei der Fahrwerkrahmen zwei Längsträger und zumindest einen zwischen diesen angeordneten Querträger aufweist, der über zumindest zwei Gelenke mit den Längsträgern verbundenen ist, wobei sich die Längsträger und der Querträger in einer Ebene parallel zur Schienenebene gegeneinander verschieben lassen.The invention relates to a chassis for a rail vehicle with at least two in wheelset bearings mounted wheelsets with axles, wheels and a chassis frame, with the chassis frame two longitudinal members and at least one arranged between these cross member has, which is connected via at least two joints with the side members, wherein the side members and the cross member in a plane parallel to the rail plane against each other let move.
Bei Fahrwerken mit starrem Fahrwerkrahmen sind bauartbedingt oftmals aufwendige Lösungen notwendig, um die erforderliche Entgleisungssicherheit zu erreichen. Dies ist vor allem der Fall, wenn Fahrwerke dieser Art einen Antrieb aufweisen. Da hierbei üblicherweise ein eigenes Bremsgehänge und Motorkonsolen am Fahrwerkrahmen vorgesehen sind, können Probleme verursacht werden, beispielsweise hinsichtlich der Längssteifigkeit des Fahrwerkrahmens, der Primärfedersteifigkeit etc. Weiters müssen die im praktischen Betrieb auftretenden Belastungen bei starren Fahrwerkrahmen mit aufwendigen Konstruktionen umgelenkt werden, um bestehende Sicherheitsvorschriften einhalten zu können, was zu sehr hohen Eigengewichten der Fahrwerke führen kann.For trolleys with rigid chassis frame are often complex design solutions necessary to achieve the required derailment safety. This is especially the Case when landing gears of this type have a drive. Since this usually has its own Brake hanger and engine consoles are provided on the chassis frame, can cause problems caused, for example, in terms of the longitudinal stiffness of the chassis frame, the Primary spring stiffness etc. Furthermore, the loads occurring in practical operation must be redirected at rigid chassis frame with elaborate constructions to existing Safety regulations, resulting in very high dead weights of the Chassis can lead.
Die oben genannten Probleme können dadurch vermieden werden, dass die Längsträger und der Querträger des Fahrwerkrahmens gelenkig miteinander verbunden sind. Damit wird erreicht, dass die Längsträger sich beispielsweise bei Kurvenfahrten in Fahrtrichtung ausrichten können, wodurch das Entgleisungsrisiko gegenüber starren Fahrwerkrahmen verringert werden kann.The above problems can be avoided by using the side members and the cross member of the chassis frame are hinged together. This is achieved that the longitudinal members align themselves, for example when cornering in the direction of travel which reduces the risk of derailment of rigid chassis can.
Ein derartiges Fahrwerk mit einem H-förmigen, verwindbaren Rahmen, bestehend aus zwei Längs- und einem Querträger, wird in der DE 43 06 848 A1 und in der EP 0 409 128 A1 beschrieben. Die Einleitung von Querkräften in den Fahrwerkrahmen erfolgt hierbei über Radsatzlager, die mit den Längsträgern starr verbunden sind.Such a chassis with an H-shaped, twistable frame, consisting of two Longitudinal and a cross member, in DE 43 06 848 A1 and in EP 0 409 128 A1 described. The introduction of shear forces in the chassis frame takes place 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 articulated frame with at least one arranged between two longitudinal members cross member which cushioned against the side members is. Again, the initiation occurring lateral forces caused by steering operations can be, via axleboxes rigidly connected to the side members.
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 möglichst verwindungssteif sein sollte, um das Entgleisungsrisiko weiter zu minimieren.In the just mentioned suspensions, the introduction of shear forces, as for example when cornering, in the chassis frame via wheelset bearings, which are connected to the longitudinal members of the chassis frame, wherein the chassis frame should be as rigid as possible with respect to these lateral forces to the risk of derailment continue to minimize.
Nachteilig an den bekannten Ausführungsformen ist, dass mit ihnen bei einem gelenkig ausgeführten Fahrwerkrahmen bauartbedingt die erwünschte Querkraftsteifigkeit nicht erreicht werden kann.A disadvantage of the known embodiments is that with them in an articulated running Undercarriage frame due to design, the desired shear force rigidity not achieved can be.
Es ist daher eine Aufgabe der Erfindung, einen gelenkigen Fahrwerkrahmen zu schaffen, der bezüglich der auftretenden Querkräfte, wie sie beispielsweise bei Kurvenfahrten vorkommen können, möglichst verwindungssteif ist.It is therefore an object of the invention to provide a hinged chassis frame, the with regard to the transverse forces that occur, for example, when cornering can, if possible, is torsionally stiff.
Diese Aufgabe wird mit einem Fahrwerk der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Radsatzlager mit dem bzw jeweils einem der Querträger des Schienenfahrzeuges verbunden sind.This object is achieved with a chassis of the type mentioned in the present invention solved that the wheelset bearing with the or each one of the cross member of the rail vehicle are connected.
Bei dem erfindungsgemäßen Fahrwerk kann die Einleitung der auftretenden Querkräfte über die Radsatzlager direkt in den betreffenden Querträger stattfinden. Die Querkrafteinleitung erfolgt somit nicht wie bei den bekannten Fahrwerken in die Längsträger des Fahrwerkrahmens. Da der Querträger gegenüber den auftretenden Querbelastungen eine wesentlich höhere Verwindungssteifigkeit aufweist als die Langträger, werden dadurch die Steifigkeitseigenschaften des Fahrwerkes gegenüber den herkömmlicherweise verwendeten Fahrwerken wesentlich verbessert.In the chassis according to the invention, the introduction of the transverse forces occurring over the wheelset bearings take place directly in the relevant cross member. The transverse force introduction thus does not take place as in the known chassis in the side members of the chassis frame. Since the cross member with respect to the transverse loads occurring a much higher Torsional stiffness than the long beam, thereby the stiffness properties of the chassis compared to the conventionally used trolleys essential improved.
Sind zwei Radsätze mit zumindest einem zwischen ihnen angeordneten Querträger vorgesehen, so besteht eine vorteilhafte Variante der Erfindung darin, dass die Radsatzlager als Schwingenlager ausgebildet sind, die um Fortsätze des Querträgers parallel zu den Achsen der Radsätze drehbar sind.If two wheel sets are provided with at least one cross member arranged between them, Thus, an advantageous variant of the invention is that the wheelset bearings as a swingarm are formed, which are parallel to the extensions of the cross member to the axles of the wheelsets are rotatable.
Eine besonders gute Übertragung von Querbelastungen wird dadurch erreicht, dass die Radsatzlager mit dem bzw. jeweils einem der Querträger so verbunden sind, dass ein Verdrehen der Radsatzlager gegen den betreffenden Querträger um eine Achse normal zur Schienenebene ausgeschlossen ist.A particularly good transmission of transverse loads is achieved in that the Wheelset bearings are connected to the or each one of the cross member so that a twisting the wheelset bearing against the respective cross member about an axis normal to the rail plane is excluded.
Bei einer anderen vorteilhaften Ausführungsform sind die Radsatzlager mit dem bzw. jeweils einem der Querträger starr verbunden sind. Eine vorteilhafte Variante dieser Ausführungsform besteht darin, dass vier Radsätze vorgesehen sind, wobei jeweils zwei Radsätze ein Paar bilden, wobei ein Querträger zwischen den zwei Paaren von Radsätzen angeordnet ist. Um bei dieser Ausführungsform eine möglichst gute Krafteinleitung von den Radsatzlagern in den Querträger zu erhalten, sind jeweils zwei in Fahrtrichtung hintereinanderliegende Radsatzlager eines Paares von Radsätzen aus einem Stück gefertigt.In another advantageous embodiment, the wheelset bearings with the or respectively one of the cross member are rigidly connected. An advantageous variant of this embodiment is that four wheelsets are provided, each pair of wheelsets a pair form, with a cross member between the two pairs of wheelsets is arranged. At this embodiment, the best possible application of force from the wheelset bearings in the Cross members are each two in the direction of travel one behind the other wheelset bearing a pair of wheelsets made in one piece.
Bei einer anderen Variante sind zwei Radsätze vorgesehen, zwischen denen ein Querträger angeordnet ist. Bei dieser Variante kann an dem Querträger ein Antrieb für das Fahrwerk angeordnet sein.In another variant, two sets of wheels are provided, between which a cross member is arranged. In this variant, a drive for the chassis can on the cross member be arranged.
In einer weiteren Ausführungsform ist an jedem Radsatz ein Antrieb für das Fahrwerk vorgesehen, der koaxial an den Achsen der Radsätze angeordnet ist.In a further embodiment, a drive for the chassis is provided on each wheelset, which is arranged coaxially to the axles of the wheelsets.
Bei dieser Ausführungsform ist es vorteilhaft, wenn zwei aufeinanderfolgende Antriebe mit zwei Stangen verbunden sind, die übereinander und im wesentlichen parallel zueinander verlaufend angeordnet sind.In this embodiment, it is advantageous if two successive drives with two rods are connected, one above the other and substantially parallel to each other are arranged.
Weiters ist es günstig, um die Radsätze von ihrer Aufgabe der Längsmitnahme des Fahrwerkrahmens zu entlasten, wenn im Bereich der Achsen der Radsätze Bremsen vorgesehen sind. Dadurch kann die Verbindung der Radsätze mit dem bzw. jeweils einem der Querträger ausschließlich auf die erforderliche Wendesteifigkeit des Radsatzes um eine Achse normal zur Schienenebene ausgelegt werden. In einer vorteilhaften Weiterbildung dieser Variante, sind die Bremsen direkt mit dem Antrieb verbunden.Furthermore, it is beneficial to the wheelsets of their task of longitudinal driving of the chassis frame to relieve, if in the area of the axles of the wheelsets brakes are provided. As a result, the connection of the wheelsets with or in each case one of the cross member exclusively on the required turning stiffness of the wheelset about an axis normal to Rail level are designed. In an advantageous development of this variant, the Brakes connected directly to the drive.
Eine günstige Ausführungsform besteht darin, dass die Radsatzlager zwischen den Rädern angeordnet sind.A favorable embodiment is that the wheelset bearings between the wheels are arranged.
In einer anderen Variante sind die Räder zwischen den Radsatzlagern angeordnet.In another variant, the wheels are arranged between the wheelset bearings.
Eine günstige Ausführungsform für die Gelenke zwischen dem Querträger und den Langträgern besteht darin, dass die Gelenke als Pendel ausgeführt sind. Um den Neigungswinkel eines Wagekastens gegen das Fahrwerk einstellen zu können, sind die Gelenke in ihrer Höhe veränderbar.A favorable embodiment for the joints between the cross member and the longitudinal members is that the joints are designed as a pendulum. To the inclination angle of a To adjust the weight box against the chassis, the joints are variable in height.
In einer anderen Ausführungsform sind die Gelenke als Kugelgelenke ausgeführt.In another embodiment, the joints are designed as ball joints.
Die Erfindung samt weiteren Vorteilen wird im folgenden anhand einiger nicht einschränkender Ausführungsbeispiele näher erläutert, die in den beigefügten Zeichnungen veranschaulicht sind.The invention together with further advantages will be described below with reference to some non-limiting Embodiments explained in more detail, which are illustrated in the accompanying drawings.
Es zeigen
Gemäß Fig. 1 weist ein Fahrwerk 1 nach einer ersten Ausführungsform der Erfindung zumindest
zwei in Radsatzlagern 2 gelagerte Radsätze 3, einen Fahrwerkrahmen 6 mit zwei Langträgern
7 sowie einen die Langträger 7 verbindenden Querträger 8 auf Als Verbindungsglied
zwischen dem Querträger 8 und den Langträgern 7 sind Gelenke 9 vorgesehen. Vorzugsweise
sind diese Gelenke 9 als Pendel, welche in Bohrungen der Längsträger 7 drehbar gelagert sind
ausgeführt. Um den Neigungswinkel eines hier nicht dargestellten Schienenfahrzeugoberbaues
gegen das Fahrwerk 1 verstellen zu können, sind die Pendel in ihrer Höhe verstellbar. In einer
anderen Ausführungsform sind die Gelenke 9 als Kugelgelenke ausgeführt. Zur Federung des
Schienenfahrzeugoberbaues, beispielsweise eines Wagenkastens, gegen das Fahrwerk 1 sind
Sekundärfedern 16 vorgesehen.According to FIG. 1, a chassis 1 according to a first embodiment of the invention at least
two mounted in
Die Radsatzlager 2 sind mit dem Querträger 8 des Schienenfahrzeuges so verbunden, dass sie
lediglich um eine zur Achse 4 der Radsätze 3 parallele Achse 19 drehbar sind. Anders gesagt,
die Radsatzlager 2 können nicht um eine Achse a, die normal zur Schienenebene ε verläuft,
verdreht werden. Dadurch können auf Räder 5 wirkende Querkräfte über Radsatzachsen 4 und
die dazugehörigen Radsatzlager 2 in den Querträger 8 eingeleitet werden. Durch diese Art der
Krafteinleitung lässt sich ein auf Querbelastungen besonders verwindungssteifes Fahrwerk 1
verwirklichen. Da der Querträger 8 parallel zur Schienenebene kein Moment auf die Langträger
7 übertragen kann, können auch auf ihn parallel zu dieser Ebene wirkenden Belastungen
nicht auf die Langträger 7 übertragen werden. Somit kann ein Verwinden des Fahrwerkes 1
unter auftretenden Querkräften durch die Erfindung vermieden werden. In der hier dargestellten
Ausführungsform der Erfindung sind Verbindungen zwischen den Radsatzlagern 2 und dem
Querträger 8 als Schwingenlager 10 ausgebildet, die um Fortsätze 11 des Querträgers 8 um
Achsen 19 parallel zur Achse 4 der Radsätzen 2 drehbar sind.The
Zwischen den Radsatzlagern 2 und den Langträgern 7 sind Primärfedern 14 vorgesehen, die bei
herkömmlicherweise verwendeten Fahrwerken 1 einen wesentlichen Einfluss auf die Entgleisungssicherheit
des Fahrwerkes 1 haben und dort daher entsprechend aufwendig hergestellt
sind. Ein weiterer Vorteil der Erfindung besteht darin, dass aufgrund der zueinander beweglichen
Langträger 7 die Steifigkeit der Primärfedern 14 keinen Einfluss auf die Entgleisungssicherheit
des Fahrwerkes 1 hat. Damit sind diese Federn einfach und kostengünstig zu bauen. Between the
Die Variante der Erfindung nach Fig. 2 weist einen im Bereich des Querträgers 8 angeordneten
Antrieb 12 auf, wobei die Übertragung von Zug- und Druckkräften zum Schienenfahrzeugsoberbau
über eine mit dem Antrieb 12 verbundene Zug/Druckstange 15 in Form einer Tiefzuganlenkung
erfolgt. Diese Art der Anlenkung ist bei dieser Ausführungsform erforderlich, um
Zwängungen des Fahrwerkes 1, welche durch Nickbewegungen des Schienenfahrzeugoberbaus
hervorgerufen werden können, zu verhindern.The variant of the invention according to FIG. 2 has a arranged in the region of the
Im Bereich der Radachsen sind Bremsen 13 vorgesehen die mit dem Antrieb 12 direkt verbunden
sind. Durch diese Anordnung wirken bei einer Bremsung auftretenden Momente direkt auf
die Achsen 4 und können über die Zug/Druckstange 15 in den Schienenfahrzeugsoberbau als
Nickmomente abgesetzt werden, wodurch die Radsatzführungen 2 von diesen Momenten
entlastet werden können.
In einer weiteren Ausführungsform der Erfindung nach Fig. 3 weist ein erfindungsgemäßes
Fahrwerk im Bereich jeder Radachse einen Antrieb 12 auf, wobei jeder Antrieb 12 direkt mit
einer Bremse 13 verbunden ist. Zur Übertragung von Zug- und Druckkräften sind zwei
Zug/Druckstangen 15 vorgesehen, die mit einem der Antriebe 12 verbunden sind.In a further embodiment of the invention according to FIG. 3, an inventive
Chassis in the range of each wheel axle to a
Die Antriebe 12 sind untereinander mit zwei Stangen 17 verbunden und vorzugsweise so
angeordnet, dass die Längsachsen der Antriebe 12 mit den Radsatzachsen zusammenfallen um
eine möglichst gute Übertragung der Antriebsmomente zu gewährleisten. Eine der Stangen 17
verbindet die beiden Antriebe 12 über dem Querträger 8 und die andere Stange 17 unter dem
Querträger 8 miteinander. Auf diese Weise wird die Anzahl der Freiheitsgrade der Antriebe 12
um zwei vermindert, nämlich um einen Rotationsfreiheitsgrad um die Radsatzachsen und einen
Translationsfreiheitsgrad parallel zur Längsrichtung der Längsträger 7, wodurch sich die
Belastung der Radsatzführungen weiter vermindern lässt.The
Durch die Absetzung der Antriebs- und Bremsmomente sowie der Zug- und Druckkräfte in
den Bereich der Radsatzachsen, wie schon bei Fig. 2 beschrieben, werden die Radsatzführungen
2 von ihrer üblichen Aufgabe der Längsmitnahme des Fahrwerkes 1 entlastet. Da die
Abstützung der Bremsen 13 über den Antrieb 12 erfolgt, können auftretende Bremsmomente
wie Antriebsmomente in den Schienenfahrzeugsoberbau als Nickmomente abgesetzt werden.
Somit können die Radsatzführungen 2 in erster Linie auf die erforderliche Wendesteifigkeit der
Radsätze 3 um eine Achse normal zur Schienenebene ε ausgelegt werden. Zur weiteren Dämpfung
des Fahrwerkes 1 sind Querdämpfer 18 vorgesehen.By the deposition of the drive and braking torques as well as the tensile and compressive forces in
the area of the wheelset axles, as already described in FIG. 2, the wheelset guides
2 relieved of their usual task of longitudinal driving of the chassis 1. Because the
Supporting the
Bezugnehmend auf Fig. 4 weist ein anderes erfindungsgemäßes Fahrwerk zwei Paare von
Radsätzen 3 auf, wobei der Querträger 8 zwischen den Paaren angeordnet ist. Um eine gute
Krafteinleitung in den Querträger 8 zu erreichen, sind die jeweils zwei hintereinanderliegenden
Radsatzlager 2 eines Paares aus einem Stück gefertigt, das mit dem Querträger 8 verschweißt
ist. Im Achsbereich der Radsätze 3 sind koaxial zu den Radsatzachsen angeordnete Antriebe
12 vorgesehen, wobei im Bereich jeder Achse Bremsen 13 vorgesehen sind, die mit den Antrieben
12 direkt in Verbindung stehen, wie schon in Fig. 3 und Fig. 2 beschrieben. Die Antriebe
12 sind miteinander über Stangen 17 miteinander verbunden, wobei je zwei übereinander
und parallel angeordnete Stange 17 zwei Antriebe 12 miteinander verbinden. Auf diese Weise
lässt sich, wie schon bei Fig. 3 beschrieben, die Anzahl der Freiheitsgrade der Antriebe 12 um
zwei reduzieren.Referring to Fig. 4, another suspension according to the invention has two pairs of
Wheel sets 3, wherein the
Bei den in Fig. 1 bis Fig. 4 dargestellten Varianten der Erfindung weisen die Fahrwerke 1
außerhalb des Fahrwerkrahmens 6 gelagerte Radsätze 2 auf. Eine Lagerung der Radsätze 2
innerhalb des Fahrwerkrahmens 6 ist jedoch genauso möglich. Diese Ausführungsform bietet
darüber hinaus die Möglichkeit, das Fahrwerk 1 aeroakustisch zu verkleiden.In the variants of the invention shown in FIG. 1 to FIG. 4, the running gears 1
