Description

Die Erfindung betrifft ein Fahrwerk für ein Schienenfahrzeug, insbesondere ein innengelagertes Fahrwerk, mit zumindest einer ersten Antriebseinheit und zumindest einem Fahrwerksrahmen, an den zumindest ein Radsatz über ein erstes Radsatzlager und ein zweites Radsatzlager gekoppelt ist, wobei die zumindest erste Antriebseinheit über eine erste Federvorrichtung sowie eine zweite Federvorrichtung auf einem ersten Radsatzlagergehäuse oder einem erstem Schwingarm und über eine dritte Federvorrichtung sowie eine vierte Federvorrichtung auf einem zweiten Radsatzlagergehäuse oder einem zweiten Schwingarm gelagert ist.The invention relates to a running gear for a rail vehicle, in particular a running gear with internal bearings, with at least one first drive unit and at least one running gear frame to which at least one wheel set is coupled via a first wheel set bearing and a second wheel set bearing, the at least first drive unit having a first spring device and a second spring device is mounted on a first wheel set bearing housing or a first swing arm and via a third spring device and a fourth spring device on a second wheel set bearing housing or a second swing arm.

Eine mechanisch entkoppelte Lagerung von Antriebseinheiten auf Fahrwerken von Schienenfahrzeugen ist insbesondere bei Hochgeschwindigkeitszügen wichtig, da dynamische Reaktionen, welche beispielsweise aufgrund von Gleislagefehlern von einem Gleis auf Komponenten des Fahrwerks übertragen werden, mit zunehmender Fahrgeschwindigkeit an Intensität zunehmen. Lager von Antriebseinheiten müssen entsprechend der zu erwartenden dynamischen Reaktionen ausgebildet bzw. dimensioniert und auf dem Fahrwerk angeordnet sein. Dabei ist insbesondere ein sorgfältig ausgelegtes Federungs- und Dämpfungsvermögen wichtig.Mechanically decoupled mounting of drive units on rail vehicle bogies is particularly important for high-speed trains, since dynamic reactions, which are transmitted from a track to bogie components, for example due to track geometry errors, increase in intensity with increasing travel speed. Bearings of drive units must be designed or dimensioned according to the dynamic reactions to be expected and arranged on the chassis. A carefully designed suspension and damping capacity is particularly important.

Weiterhin müssen bei einer Anordnung und Dimensionierung von Lagern von Antriebseinheiten insbesondere bei innengelagerten Fahrwerken und insbesondere bei zu Radsatzwellen koaxialen Antrieben häufig stark eingeschränkte Bauraumbudgets berücksichtigt werden.Furthermore, when arranging and dimensioning bearings of drive units, particularly in the case of chassis with internal bearings and in particular in the case of drives that are coaxial to wheelset shafts, very limited installation space budgets must often be taken into account.

Aus dem Stand der Technik ist beschreibt beispielsweise die WO 2017/133954 A1 ein innengelagertes Fahrwerk mit einem Fahrwerksrahmen, einem querliegenden Antriebsmotor und einem Getriebe. Zwischen dem Antriebsmotor und dem Fahrwerksrahmen sind zumindest drei elastische Lager angeordnet, wobei auf zumindest einem von zwei Längsträgern des Fahrwerksrahmens je eines dieser elastischen Lager vorgesehen ist.From the prior art, for example, describes the WO 2017/133954 A1 an internally mounted undercarriage with an undercarriage frame, a transverse drive motor and a gearbox. At least three elastic bearings are arranged between the drive motor and the chassis frame at least one of two longitudinal beams of the running gear frame is provided with one of these elastic bearings.

Zwischen dem Antriebsmotor und dem Fahrwerksrahmen können Befestigungsmodule vorgesehen sein, welche einen raschen Tausch der Antriebsmotoren ermöglichen.Fastening modules can be provided between the drive motor and the chassis frame, which enable the drive motors to be replaced quickly.

Weiterhin ist die EP 2 964 506 B1 bekannt, in der ein Fahrwerk für ein Schienenfahrzeug beschrieben ist, das einen Fahrwerksrahmen, eine Antriebseinheit und insbesondere innengelagerte Radsätze aufweist. Die Antriebseinheit umfasst einen Elektromotor, ein Getriebe sowie eine Kupplung und ist zumindest teilweise elastisch bzw. beweglich auf dem Fahrwerksahmen gelagert. Zwischen der Antriebseinheit und Radsatzlagergehäusen sind Federvorrichtungen vorgesehen. Weiterhin ist zwischen der Antriebseinheit und einem Radsatzlagergehäuse ein Teleskopdämpfer angeordnet, welcher quer bzw. vorwiegend quer zur Fahrtrichtung ausgerichtet ist.Furthermore, the EP 2 964 506 B1 is known, in which a running gear for a rail vehicle is described, which has a running gear frame, a drive unit and, in particular, wheel sets with internal bearings. The drive unit includes an electric motor, a gear and a clutch and is mounted at least partially elastically or movably on the chassis frame. Spring devices are provided between the drive unit and wheel set bearing housings. Furthermore, a telescopic damper is arranged between the drive unit and a wheelset bearing housing, which is aligned transversely or predominantly transversely to the direction of travel.

Die genannten Ansätze weisen in ihren bekannten Formen den Nachteil einer ein vorhandenes Bauraumbudget stark ausnutzenden Antriebslagerung bzw. Antriebsfederung und -Dämpfung mit insbesondere quer zur Fahrtrichtung geringen Federwegen und einer starken Übertragung von Vibrationen auf.In their known forms, the approaches mentioned have the disadvantage of a drive bearing or drive springing and damping that makes great use of an existing installation space budget, with short spring deflections, in particular transversely to the direction of travel, and strong transmission of vibrations.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik weiterentwickeltes Fahrwerk mit einer kompakten aber dennoch stark vibrationssenkenden Antriebslagerung anzugeben.The invention is therefore based on the object of specifying a chassis which is further developed compared to the prior art and has a compact drive bearing which nevertheless greatly reduces vibration.

Erfindungsgemäß wird diese Aufgabe gelöst mit einem Fahrwerk der eingangs genannten Art,
bei dem zumindest zwischen dem ersten Radsatzlagergehäuse oder dem erstem Schwingarm einerseits und der zumindest ersten Antriebseinheit andererseits eine erste Dämpfervorrichtung, welche einen Dämpfer und, zu dem Dämpfer wirkungsmäßig in Serie geschaltet, einen ersten Anschlagpuffer und einen zweiten Anschlagpuffer aufweist, inAccording to the invention this object is achieved with a chassis of the type mentioned,
in which at least between the first wheel set bearing housing or the first swing arm on the one hand and the at least first drive unit on the other hand there is a first damper device which has a damper and, functionally connected in series with the damper, a first stop buffer and a second stop buffer, in

wirkungsmäßiger Parallelschaltung zu der ersten Federvorrichtung, der zweiten Federvorrichtung, der dritten Federvorrichtung und der vierten Federvorrichtung angeordnet ist.effective parallel connection to the first spring device, the second spring device, the third spring device and the fourth spring device is arranged.

Aufgrund des ersten Anschlagpuffers und des zweiten Anschlagpuffers auf der ersten Dämpfervorrichtung kann diese mit einem bestimmten Abstand zu umgebenden Komponenten des Fahrwerks (z.B. zu dem ersten Radsatzlagergehäuse) eingebaut sein. Dadurch werden einerseits freie Dehnungs- und Stauchungsvorgänge der ersten Federvorrichtung, der zweiten Federvorrichtung, der dritten Federvorrichtung sowie der vierten Federvorrichtung ermöglicht und es wird andererseits, ab einem diese freien Dehnungs- und Stauchungsvorgänge begrenzenden Eingriff des ersten Anschlagpuffers oder des zweiten Anschlagpuffers, eine definierte Dämpfung von Bewegungen der ersten Antriebseinheit erreicht.Due to the first bump stop and the second bump stop on the first damper device, this can be installed at a certain distance from surrounding components of the chassis (e.g. from the first wheel set bearing housing). As a result, on the one hand free expansion and compression processes of the first spring device, the second spring device, the third spring device and the fourth spring device are made possible and on the other hand, defined damping is achieved from an intervention of the first stop buffer or the second stop buffer that limits these free expansion and compression processes achieved by movements of the first drive unit.

Durch Ermöglichung der freien Dehnungs- und Stauchungsvorgänge werden zwischen der ersten Antriebseinheit und dem ersten Radsatzlagergehäuse und dem zweiten Radsatzlagergehäuse übertragene Vibrationen reduziert. Aufgrund des begrenzenden Eingriffs des ersten Anschlagpuffers oder des zweiten Anschlagpuffers wird ein übermäßiges Anwachsen von Federkräften vermieden.By enabling the free expansion and compression processes, vibrations transmitted between the first drive unit and the first axle box and the second axle box are reduced. Due to the limiting engagement of the first jounce bumper or the second jounce bumper, excessive build-up of spring forces is avoided.

Es ist günstig, wenn die erste Federvorrichtung, die zweite Federvorrichtung, die dritte Federvorrichtung und die vierte Federvorrichtung in Richtung einer Fahrwerkslängsachse vorgespannt sind.It is favorable if the first spring device, the second spring device, the third spring device and the fourth spring device are prestressed in the direction of a longitudinal axis of the running gear.

Durch diese Maßnahme werden entsprechende Lagerreaktionen erzeugt und Gewichtskräfte sowie Antriebs- und Bremskräfte kompensiert.Appropriate bearing reactions are generated by this measure and weight forces as well as drive and braking forces are compensated.

Eine vorteilhafte Ausgestaltung erhält man, wenn zumindest die erste Federvorrichtung und die zweite Federvorrichtung einander gegenüberliegend angeordnet sind.An advantageous embodiment is obtained when at least the first spring device and the second spring device are arranged opposite one another.

Durch diese Maßnahme wird eine Federungs- und Stützwirkung in zwei einander entgegengesetzten Richtungen erzielt, wodurch Antriebs- und Bremskräfte unterschiedlicher Wirkrichtungen kompensiert werden können.By this measure, a suspension and support effect is achieved in two opposite directions, whereby Driving and braking forces of different directions can be compensated.

Es ist weiterhin günstig, wenn die zumindest erste Dämpfervorrichtung der ersten Federvorrichtung und der zweiten Federvorrichtung zwischengeordnet ist.It is also favorable if the at least first damper device is arranged between the first spring device and the second spring device.

Dadurch wird eine besonders platzsparende Antriebslagerung erzielt, wodurch beispielsweise eine mit einer Oberseite des ersten Radsatzlagergehäuses fluchtende Anordnung der ersten Federvorrichtung, der zweiten Federvorrichtung und der Dämpfervorrichtung ermöglicht wird.This achieves a particularly space-saving drive bearing arrangement, which makes it possible, for example, to arrange the first spring device, the second spring device and the damper device in alignment with an upper side of the first wheel set bearing housing.

Es kann vorteilhaft sein, wenn die erste Federvorrichtung, die zweite Federvorrichtung, die dritte Federvorrichtung und die vierte Federvorrichtung als Schichtfedern ausgebildet sind.It can be advantageous if the first spring device, the second spring device, the third spring device and the fourth spring device are designed as layered springs.

Schichtfedern weisen in drei Raumrichtungen definierte Steifigkeiten auf, wodurch eine hohe Belastbarkeit der ersten Federvorrichtung, der zweiten Federvorrichtung, der dritten Federvorrichtung und der vierten Federvorrichtung in drei Raumrichtungen erzielt und flexible Einbaulagen ermöglicht werden. Weiterhin wird aufgrund der Schichtfedern eine gewisse Eigendämpfung der ersten Federvorrichtung, der zweiten Federvorrichtung, der dritten Federvorrichtung und der vierten Federvorrichtung erreicht.Layered springs have rigidities defined in three spatial directions, whereby a high load capacity of the first spring device, the second spring device, the third spring device and the fourth spring device is achieved in three spatial directions and flexible installation positions are made possible. Furthermore, due to the layered springs, a certain self-damping of the first spring device, the second spring device, the third spring device and the fourth spring device is achieved.

Eine günstige Lösung wird erzielt, wenn die erste Federvorrichtung, die zweite Federvorrichtung, die dritte Federvorrichtung und die vierte Federvorrichtung als Drahtseildämpfer ausgebildet sind.A favorable solution is achieved when the first spring device, the second spring device, the third spring device and the fourth spring device are designed as wire cable dampers.

Durch diese Maßnahme wird effektive Absorption von Stößen zwischen der ersten Antriebseinheit einerseits und dem ersten Radsatzlagergehäuse sowie dem zweiten Radsatzlagergehäuse andererseits erreicht.This measure effectively absorbs impacts between the first drive unit on the one hand and the first wheel set bearing housing and the second wheel set bearing housing on the other hand.

Eine vorteilhafte Lösung wird erreicht, wenn der Dämpfer der zumindest ersten Dämpfervorrichtung als hydraulisches Lager ausgeführt ist.An advantageous solution is achieved when the damper of at least the first damper device is designed as a hydraulic bearing.

Durch diese Maßnahme werden ab dem Eingriff des ersten Anschlagpuffers eine Antriebslagerung mit in allen drei Raumrichtungen effektiver Schwingungsdämpfung einerseits und definierter Versteifung andererseits erreicht.As a result of this measure, a drive bearing with effective vibration damping in all three spatial directions on the one hand and defined stiffening on the other hand is achieved from the engagement of the first stop buffer.

Es ist günstig, wenn zumindest aus dem ersten Radsatzlagergehäuse ein erster Halter, mit welchem die erste Federvorrichtung verbunden ist, sowie ein zweiter Halter, mit welchem die zweite Federvorrichtung verbunden ist, ausgeformt sind.It is advantageous if a first holder, to which the first spring device is connected, and a second holder, to which the second spring device is connected, are formed at least from the first wheel set bearing housing.

Durch diese Maßnahme kann auf separate, beispielsweise mit dem ersten Radsatzlagergehäuse verschraubte Adapter oder Schweißkonsolen zur Befestigung der ersten Federvorrichtung und der zweiten Federvorrichtung verzichtet werden.This measure makes it possible to dispense with separate adapters or welding brackets, for example screwed to the first wheel set bearing housing, for fastening the first spring device and the second spring device.

Eine vorteilhafte Ausgestaltung erhält man, wenn die zumindest erste Dämpfervorrichtung von dem ersten Radsatzlagergehäuse oder dem Schwingarm, dem ersten Halter, dem zweiten Halter und einem mit dem ersten Halter und dem zweiten Halter verbundenen Deckel ummantelt ist.An advantageous embodiment is obtained when the at least first damper device is encased by the first wheel set bearing housing or the swing arm, the first holder, the second holder and a cover connected to the first holder and the second holder.

Durch diese Maßnahme wird ein gewisser Schutz der ersten Dämpfervorrichtung (z.B. gegen Steinschlag) erzielt und darüber hinaus fungieren das erste Radsatzlagergehäuse oder der Schwingarm einerseits sowie der Deckel andererseits als Kontaktkörper für den ersten Anschlagpuffer und den zweiten Anschlagpuffer.This measure provides a certain degree of protection for the first damper device (e.g. against stone chipping) and, in addition, the first wheel set bearing housing or the swing arm on the one hand and the cover on the other act as contact bodies for the first bump stop and the second bump stop.

Es ist ferner günstig, wenn mit der zumindest ersten Antriebseinheit zumindest ein erster Träger gekoppelt ist, mit welchem die erste Federvorrichtung, die zweite Federvorrichtung sowie die zumindest erste Dämpfervorrichtung verbunden sind.It is also favorable if at least one first carrier is coupled to the at least first drive unit, to which the first spring device, the second spring device and the at least first damper device are connected.

Der erste Träger fungiert als Adaptermodul und ist somit austauschbar. Durch diese Maßnahme können die erste Federvorrichtung, die zweite Federvorrichtung sowie die erste Dämpfervorrichtung in mit dem ersten Träger verbundenem Zustand und deshalb rasch getauscht werden.The first carrier acts as an adapter module and is therefore interchangeable. This measure allows the first The spring device, the second spring device and the first damper device are in the state connected to the first carrier and are therefore quickly exchanged.

Weiterhin können dadurch bei einem Ersatz der ersten Antriebseinheit, beispielsweise durch eine Antriebseinheit mit kleineren Abmessungen als jene der ersten Antriebseinheit, die erste Federvorrichtung, die zweite Federvorrichtung sowie die erste Dämpfervorrichtung weiter eingesetzt bleiben. Es muss in einem derartigen Fall, sofern erforderlich, lediglich der erste Träger getauscht werden.Furthermore, when the first drive unit is replaced, for example by a drive unit with smaller dimensions than those of the first drive unit, the first spring device, the second spring device and the first damper device can continue to be used. In such a case, if necessary, only the first carrier has to be exchanged.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below using exemplary embodiments.

Koaxial zu dem ersten Radsatz ist eine erste Antriebseinheit 1 angeordnet, koaxial zu dem zweiten Radsatz eine nicht dargestellte zweite Antriebseinheit.A first drive unit 1 is arranged coaxially to the first wheel set, and a second drive unit (not shown) is arranged coaxially to the second wheel set.

Zwischen der ersten Antriebseinheit 1 und dem Fahrwerksrahmen sowie zwischen der zweiten Antriebseinheit und dem Fahrwerksrahmen sind nicht gezeigte Drehmomentenstützen zur Übertragung von Antriebs- und Bremsmomenten bzw. deren Einleitung von der ersten Antriebseinheit 1 und der zweiten Antriebseinheit in den Fahrwerksrahmen angeordnet.Between the first drive unit 1 and the chassis frame and between the second drive unit and the chassis frame are arranged torque arms (not shown) for transmitting drive and braking torques or introducing them from the first drive unit 1 and the second drive unit into the chassis frame.

Die erste Antriebseinheit 1 ist über eine erste Federvorrichtung 2, eine zweite Federvorrichtung 3 und eine erste Dämpfervorrichtung 5, welche eine erste Lagervorrichtung bilden, mit dem ersten Radsatzlagergehäuse 4 sowie über eine dritte Federvorrichtung, eine vierte Federvorrichtung und eine zweite Dämpfervorrichtung, welche eine nicht dargestellte zweite Lagervorrichtung bilden, mit dem zweiten Radsatzlagergehäuse verbunden.The first drive unit 1 is connected via a first spring device 2, a second spring device 3 and a first damper device 5, which form a first bearing device, to the first wheel set bearing housing 4 and via a third spring device, a fourth spring device and a second damper device, which is a non-illustrated form the second bearing device, connected to the second wheel set bearing housing.

Die zweite Antriebseinheit ist über eine fünfte Federvorrichtung, eine sechste Federvorrichtung und eine dritte Dämpfervorrichtung, welche eine nicht gezeigte dritte Lagervorrichtung bilden, mit dem dritten Radsatzlagergehäuse sowie über eine siebente Federvorrichtung, eine achte Federvorrichtung und eine vierte Dämpfervorrichtung, welche eine nicht dargestellte vierte Lagervorrichtung bilden, mit dem vierten Radsatzlagergehäuse verbunden.The second drive unit is connected via a fifth spring device, a sixth spring device and a third damper device, which form a third bearing device (not shown), to the third wheel set bearing housing and via a seventh spring device, an eighth spring device and a fourth damper device, which form a fourth bearing device (not shown). , connected to the fourth wheel set bearing housing.

Erfindungsgemäß ist es auch vorstellbar, zwischen der ersten Antriebseinheit 1 und dem ersten Radsatzlagergehäuse 4 bzw. dem zweiten Radsatzlagergehäuse beispielsweise nur die erste Dämpfervorrichtung 5 sowie zwischen der zweiten Antriebseinheit und dem dritten Radsatzlagergehäuse bzw. dem vierten Radsatzlagergehäuse nur die dritte Dämpfervorrichtung vorzusehen, d.h. auf die zweite Dämpfervorrichtung und die vierte Dämpfervorrichtung zu verzichten.According to the invention, it is also conceivable to provide, for example, only the first damper device 5 between the first drive unit 1 and the first wheel set bearing housing 4 or the second wheel set bearing housing and only the third damper device between the second drive unit and the third wheel set bearing housing or the fourth wheel set bearing housing, i.e. on the to dispense with the second damper device and the fourth damper device.

Die erste Lagervorrichtung, die zweite Lagervorrichtung, die dritte Lagervorrichtung und die vierte Lagervorrichtung gleichen einander im Hinblick auf konstruktive und funktionale Eigenschaften. Es ist hier daher nur die erste Lagervorrichtung im Detail beschrieben.The first bearing device, the second bearing device, the third bearing device and the fourth bearing device are similar to one another with regard to structural and functional properties. Therefore, only the first bearing device is described in detail here.

Die erste Lagervorrichtung ist im Bereich einer ersten Antriebsstirnseite 15 der ersten Antriebseinheit 1 vorgelagert.The first bearing device is mounted in front of the first drive unit 1 in the area of a first drive end face 15 .

Die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 sind als Schichtfedern ausgeführt und liegend angeordnet, d.h. ihre Längsachsen verlaufen in einem nicht ausgelenkten Zustand der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3, welcher in Fig. 1 gezeigt ist, parallel zu einer Fahrwerkslängsachse 8. Dadurch wird eine günstige Ausnutzung eines vorhandenen Bauraumbudgets in Richtung einer Fahrwerkshochachse 10 und somit eine kompakte Bauweise erzielt.The first spring device 2 and the second spring device 3 are designed as layer springs and arranged horizontally, ie their longitudinal axes run in a non-deflected State of the first spring device 2 and the second spring device 3, which in 1 is shown, parallel to a longitudinal axis 8 of the running gear. As a result, a favorable utilization of an existing construction space budget in the direction of a vertical axis 10 of the running gear and thus a compact construction are achieved.

Das erste Radsatzlagergehäuse 4 weist einen ersten Halter 11 und einen zweiten Halter 12 auf, welche über einen Gießprozess aus dem ersten Radsatzlagergehäuse 4 ausgeformt sind und in Richtung der Fahrwerkshochachse 10 verlaufen.The first wheel set bearing housing 4 has a first holder 11 and a second holder 12 which are formed from the first wheel set bearing housing 4 via a casting process and run in the direction of the running gear vertical axis 10 .

Die erste Federvorrichtung 2 ist über eine erste Grundplatte 21 mit einem ersten Träger 14 verbunden und über eine als Montagewinkel ausgebildete zweite Grundplatte 22 mit dem ersten Halter 11.The first spring device 2 is connected to a first carrier 14 via a first base plate 21 and to the first holder 11 via a second base plate 22 designed as a mounting bracket.

Die erste Grundplatte 21 weist einen ersten Gewindebolzen 17 und einen zweiten Gewindebolzen 18 auf, über welche die erste Federvorrichtung 2 mittels entsprechender Muttern mit dem ersten Träger 14 verschraubt ist.The first base plate 21 has a first threaded bolt 17 and a second threaded bolt 18, via which the first spring device 2 is screwed to the first support 14 by means of corresponding nuts.

Die zweite Federvorrichtung 3 ist über eine dritte Grundplatte 23 mit dem ersten Träger 14 verbunden und über eine als Montagewinkel ausgebildete vierte Grundplatte 24 mit dem zweiten Halter 12.The second spring device 3 is connected to the first carrier 14 via a third base plate 23 and to the second holder 12 via a fourth base plate 24 designed as a mounting bracket.

Die dritte Grundplatte 23 weist einen dritten Gewindebolzen 19 und einen vierten Gewindebolzen 20 auf, über welche die zweite Federvorrichtung 3 mittels entsprechender Muttern mit dem ersten Träger 14 verschraubt ist.The third base plate 23 has a third threaded bolt 19 and a fourth threaded bolt 20, via which the second spring device 3 is screwed to the first carrier 14 by means of corresponding nuts.

Oberhalb des ersten Halters 11 und des zweiten Halters 12 ist ein Deckel 13 angeordnet. Dieser ist mittels einer ersten Schraube 25, einer in Fig. 2 gezeigten zweiten Schraube 26, einer dritten Schraube 27 und einer in Fig. 2 sichtbaren vierten Schraube 28, die als Sechskantschrauben mit Sacklöchern ausgeführt sind, mit Oberseiten des ersten Halters 11 und des zweiten Halters 12 sowie mit Deckseiten der zweiten Grundplatte 22 und der vierten Grundplatte 24, wobei diese Deckseiten in Richtung der Fahrwerkslängsachse 8 ausgerichtet sind, verbunden. Die zweite Grundplatte 22 ist im Bereich ihrer Deckseite zwischen dem Deckel 13 und dem ersten Halter 11 geklemmt, die vierte Grundplatte 24 im Bereich ihrer Deckseite zwischen dem Deckel 13 und dem zweiten Halter 12.A cover 13 is arranged above the first holder 11 and the second holder 12 . This is by means of a first screw 25, an in 2 shown second screw 26, a third screw 27 and in 2 visible fourth screw 28, which are designed as hexagonal screws with blind holes, with tops of the first holder 11 and the second holder 12 and with cover sides of the second base plate 22 and the fourth base plate 24, these cover sides are aligned in the direction of the chassis longitudinal axis 8, connected. The second base plate 22 is clamped in the area of its top side between the cover 13 and the first holder 11, the fourth base plate 24 in the area of its top side between the cover 13 and the second holder 12.

Längsachsen der erste Schraube 25, der zweiten Schraube 26, der dritten Schraube 27 und der vierten Schraube 28 sind in Richtung der Fahrwerkshochachse 10 ausgerichtet.Longitudinal axes of the first screw 25, the second screw 26, the third screw 27 and the fourth screw 28 are aligned in the direction of the vertical axis 10 of the running gear.

Der erste Träger 14 ist mittels einer fünften Schraube 29, einer in Fig. 2 sichtbaren sechsten Schraube 30, einer siebenten Schraube 31, einer in Fig. 2 gezeigten achten Schraube 32 sowie weiteren, nicht gezeigten Schrauben mit der ersten Antriebseinheit 1 verschraubt. Längsachsen der fünften Schraube 29, der sechsten Schraube 30, der siebenten Schraube 31, der achten Schraube 32 sowie der weiteren Schrauben verlaufen in Richtung der Fahrwerkshochachse 10.The first carrier 14 is secured by a fifth screw 29, an in 2 visible sixth screw 30, a seventh screw 31, an in 2 shown eighth screw 32 and other screws, not shown, are screwed to the first drive unit 1 . Longitudinal axes of the fifth screw 29, the sixth screw 30, the seventh screw 31, the eighth screw 32 and the other screws run in the direction of the chassis vertical axis 10.

Der erste Träger 14 ist im Bereich der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 rahmenförmig ausgebildet. Die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 sind, einander gegenüberliegend, in diesem rahmenförmigen Bereich zwischen dem ersten Träger 14 und dem ersten Halter 11 bzw. dem zweiten Halter 12 unter Vorspannung angeordnet, wobei entsprechende Vorspannkräfte der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 einander entgegengesetzt wirken.The first carrier 14 is designed in the shape of a frame in the area of the first spring device 2 and the second spring device 3 . The first spring device 2 and the second spring device 3 are arranged opposite each other in this frame-shaped area between the first support 14 and the first holder 11 or the second holder 12 under pretension, with corresponding pretensioning forces of the first spring device 2 and the second spring device 3 act opposite to each other.

Die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 können in drei Raumrichtungen (z.B. durch Antriebs-, Brems- und Gewichtskräfte der ersten Antriebseinheit 1) belastet werden und weisen entsprechende Steifigkeiten in Richtung der Fahrwerkslängsachse 8, in Richtung einer in Fig. 2 sichtbaren Fahrwerksquerachse 9 sowie in Richtung der Fahrwerkshochachse 10 auf, wobei die Steifigkeit in Richtung der Fahrwerkshochachse 10 am größten und in Richtung der Fahrwerksquerachse 9 am geringsten ist, wobei in Richtung der Fahrwerksquerachse 9 maximale Auslenkungen von 15 mm vorgesehen sind, wodurch eine Verschleißsenkung und somit eine Lebensdauersteigerung der ersten Lagervorrichtung erzielt wird.The first spring device 2 and the second spring device 3 can be loaded in three spatial directions (e.g. by driving, braking and weight forces of the first drive unit 1) and have corresponding rigidities in the direction of the chassis longitudinal axis 8, in the direction of an in 2 visible chassis transverse axis 9 and in the direction of the chassis vertical axis 10, the stiffness in the direction of the chassis vertical axis 10 being greatest and in the direction of the chassis transverse axis 9 being lowest, with maximum deflections of 15 mm in the direction of the chassis transverse axis 9 are provided, whereby a reduction in wear and thus an increase in the service life of the first bearing device is achieved.

Als Alternative zu einer Ausführung der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 als Schichtfedern können diese auch als Drahtseildämpfer oder Fluidfedern (z.B. als Luftfedern oder Öldruckfedern) ausgebildet sein.As an alternative to an embodiment of the first spring device 2 and the second spring device 3 as layer springs, these can also be designed as wire cable dampers or fluid springs (e.g. as air springs or oil pressure springs).

Bei einer Ausführung als Drahtseildämpfer sind entsprechende Befestigungsmodule mit dem ersten Träger 14 und dem ersten Halter 11 bzw. dem zweiten Halter 12 verbunden. Zwischen den Befestigungsmodulen bzw. zwischen dem ersten Träger 14 und dem ersten Halter 11 einerseits und dem ersten Träger 14 und dem zweiten Halter 12 andererseits sind Drahtseile gespannt, welche eine Federungs- und Dämpfungswirkung zwischen der ersten Antriebseinheit 1 und dem ersten Radsatzlagergehäuse 4 erzeugen.In the case of an embodiment as a wire cable damper, corresponding fastening modules are connected to the first carrier 14 and the first holder 11 or the second holder 12 . Between the fastening modules or between the first carrier 14 and the first holder 11 on the one hand and the first carrier 14 and the second holder 12 on the other hand, wire ropes are stretched, which produce a springing and damping effect between the first drive unit 1 and the first wheel set bearing housing 4.

Bei einer Ausführung der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 als Luftfedern sind die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 an ein Druckluftsystem des Schienenfahrzeugs, beispielsweise für eine Bremse und eine Sekundärfeder, pneumatisch, d.h. über Druckluftleitungen angeschlossen. Zwischen dem ersten Träger 14 und dem ersten Halter 11 bzw. dem zweiten Halter 12 sind bei der Ausführung der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 als Luftfedern entsprechende Luftbälge angeordnet, deren Steifigkeiten über eine elektronische Luftfedersteuereinrichtung eingestellt werden können.In an embodiment of the first spring device 2 and the second spring device 3 as air springs, the first spring device 2 and the second spring device 3 are connected to a compressed air system of the rail vehicle, for example for a brake and a secondary spring, pneumatically, i.e. via compressed air lines. In the embodiment of the first spring device 2 and the second spring device 3 as air springs, corresponding air bellows are arranged between the first carrier 14 and the first holder 11 or the second holder 12, the stiffness of which can be adjusted via an electronic air spring control device.

Mit einer Oberseite des ersten Trägers 14 ist weiterhin die erste Dämpfervorrichtung 5 verschraubt, wobei zwischen dem ersten Träger 14 und der ersten Dämpfervorrichtung 5 eine neunte Schraube 33, eine in Fig. 2 sichtbare zehnte Schraube 34, eine elfte Schraube 35 sowie eine in Fig. 2 gezeigte zwölfte Schraube 36, welche als Sechskant-Sacklochschrauben ausgebildet sind, vorgesehen sind.The first damper device 5 is also screwed to an upper side of the first carrier 14, with a ninth screw 33 between the first carrier 14 and the first damper device 5, a screw in 2 visible tenth screw 34, an eleventh screw 35 and an in 2 shown twelfth screw 36, which are designed as hexagonal blind screws, are provided.

Die erste Dämpfervorrichtung 5 ist zwischen der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 angeordnet, mit diesen wirkungsmäßig parallel geschaltet und von dem ersten Radsatzlagergehäuse 4, dem ersten Halter 11, dem zweiten Halter 12 und dem Deckel 13 ummantelt. Damit wird einerseits eine besonders platzsparende Anordnung und andererseits auch ein Schutz der ersten Dämpfervorrichtung 5 (z.B. gegen Steinschlag) erzielt.The first damper device 5 is arranged between the first spring device 2 and the second spring device 3 , is connected in parallel with these in terms of effect and is encased by the first wheel set bearing housing 4 , the first holder 11 , the second holder 12 and the cover 13 . In this way, on the one hand, a particularly space-saving arrangement and, on the other hand, protection of the first damper device 5 (e.g. against stone chipping) is achieved.

Die erste Dämpfervorrichtung 5 weist einen als hydraulisches Lager ausgeführten Dämpfer sowie an ihrer Unterseite einen ersten Anschlagpuffer 6 und an ihrer Oberseite einen zweiten Anschlagpuffer 7 auf. Der Dämpfer umfasst zwei mit Hydraulikflüssigkeit gefüllte Kammern und weist Steifigkeiten und Dämpfungswirkungen in Richtung der Fahrwerkslängsachse 8, der Fahrwerksquerachse 9 und der Fahrwerkshochachse 10 auf. Mittels des hydraulischen Lagers wird sowohl bei geringen als auch bei hohen Erregerfrequenzen eine effektive Dämpfung bewirkt.The first damper device 5 has a damper designed as a hydraulic bearing and a first stop buffer 6 on its underside and a second stop buffer 7 on its upper side. The damper comprises two chambers filled with hydraulic fluid and exhibits stiffness and damping effects in the direction of the longitudinal axis 8 of the chassis, the transverse axis 9 of the chassis and the vertical axis 10 of the chassis. Effective damping is achieved by means of the hydraulic bearing at both low and high excitation frequencies.

Erfindungsgemäß kann statt des hydraulischen Lagers auch ein Gummidämpfer als Dämpfer der ersten Dämpfervorrichtung 5 eingesetzt sein.According to the invention, a rubber damper can also be used as a damper of the first damper device 5 instead of the hydraulic bearing.

Der Dämpfer ist mit dem ersten Anschlagpuffer 6 und dem zweiten Anschlagpuffer 7 wirkungsmäßig in Serie bzw. in Reihe geschaltet. Zwischen dem ersten Anschlagpuffer 6 und dem ersten Radsatzlagergehäuse 4 sowie zwischen dem zweiten Anschlagpuffer 7 und dem Deckel 13, d.h. zwischen dem ersten Anschlagpuffer 6 bzw. dem zweiten Anschlagpuffer 7 und diese umgebenden Komponenten des Fahrwerks, ist in dem in Fig. 1 dargestellten, nicht ausgelenkten Zustand der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 jeweils ein Abstand von 5 mm vorgesehen.The damper is functionally connected in series or in series with the first stop buffer 6 and the second stop buffer 7 . In 1 shown, non-deflected state of the first spring device 2 and the second spring device 3 are each provided a distance of 5 mm.

Lenken die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 beispielswiese in Richtung der Fahrwerkshochachse 10 nach unten aus, so trifft der erste Anschlagpuffer 6 nach einem Weg von 5 mm bezogen auf den gezeigten, nicht ausgelenkten Zustand der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 (d.h. in einem definierten Auslenkungszustand der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3) auf das erste Radsatzlagergehäuse 4 und stützt sich darauf ab bzw. kann darauf gleiten (der erste Anschlagpuffer 6 fungiert also auch als Gleitplatte). Erst mit Eingriff des ersten Anschlagpuffers 6 bzw. dessen Kontakt mit dem ersten Radsatzlagergehäuse 4 setzt die Dämpfungswirkung des Dämpfers ein.If the first spring device 2 and the second spring device 3 deflect downwards, for example in the direction of the chassis vertical axis 10, the first one hits Stop buffer 6 after a travel of 5 mm based on the shown non-deflected state of the first spring device 2 and the second spring device 3 (i.e. in a defined deflection state of the first spring device 2 and the second spring device 3) on the first wheel set bearing housing 4 and is supported on it from or can slide on it (the first stop buffer 6 also functions as a sliding plate). Only when the first stop buffer 6 engages or when it makes contact with the first wheel set bearing housing 4 does the damping effect of the damper begin.

Lenken die erste Federvorrichtung 2 und die zweite Federvorrichtung 3 beispielswiese in Richtung der Fahrwerkshochachse 10 nach oben aus, so trifft der zweite Anschlagpuffer 7 nach einem Weg von 5 mm bezogen auf den gezeigten, nicht ausgelenkten Zustand der ersten Federvorrichtung 2 und der zweiten Federvorrichtung 3 auf den Deckel 13 und stützt sich darauf ab bzw. kann darauf gleiten (auch der zweite Anschlagpuffer 7 kann als Gleitplatte fungieren). Mit Eingriff des zweiten Anschlagpuffers 7 bzw. dessen Kontakt mit dem Deckel 13 setzt die Dämpfungswirkung des Dämpfers ein.If the first spring device 2 and the second spring device 3 deflect upwards, for example in the direction of the vertical axis 10 of the running gear, the second stop buffer 7 hits after a travel of 5 mm in relation to the shown non-deflected state of the first spring device 2 and the second spring device 3 the cover 13 and is supported on it or can slide on it (the second stop buffer 7 can also function as a slide plate). When the second stop buffer 7 engages or makes contact with the cover 13, the damping effect of the damper begins.

Aufgrund des allmählichen Eingriffs der ersten Dämpfervorrichtung 5 und der zweiten Dämpfervorrichtung wird bei verhältnismäßig kleinen Federwegen auch auf Strecken mit schlechtem Gleiszustand eine effektive Dämpfung von Bewegungen bzw. Schwingungen zwischen der ersten Antriebseinheit 1 und dem ersten Radsatzlagergehäuse 4 erzielt.Due to the gradual engagement of the first damper device 5 and the second damper device, effective damping of movements or vibrations between the first drive unit 1 and the first wheel set bearing housing 4 is achieved with relatively small spring deflections even on routes with poor track conditions.

Erfindungsgemäß ist es auch denkbar, dass der erste Anschlagpuffer 6 und/oder der zweite Anschlagpuffer 7 der ersten Dämpfervorrichtung 5 von dem Dämpfer räumlich, jedoch nicht funktional, getrennt sind/ist. Beispielsweise kann der erste Anschlagpuffer 6 auf dem ersten Radsatzlagergehäuse 4 angeordnet sein und/oder der zweite Anschlagpuffer 7 auf einer Unterseite des Deckels 13.According to the invention, it is also conceivable for the first stop buffer 6 and/or the second stop buffer 7 of the first damper device 5 to be spatially, but not functionally, separated from the damper. For example, the first stop buffer 6 can be arranged on the first wheel set bearing housing 4 and/or the second stop buffer 7 on an underside of the cover 13.

Fig. 2 zeigt jene in Fig. 1 dargestellte Variante eines erfindungsgemäßen Fahrwerks als Grundriss. Es werden daher teilweise gleiche Bezugszeichen wie in Fig. 1 verwendet. 2 shows those in 1 illustrated variant of a chassis according to the invention as a floor plan.
