Description

Die Erfindung betrifft ein Laufwerk für Schienenfahrzeuge nach dem Oberbegriff des Patentanspruches 1The invention relates to a running gear for rail vehicles according to the preamble of claim 1

Ziel der Erfindung ist die Schaffung von Laufwerken, die auch für hohe Geschwindigkeiten, z.B. über 160 km/h, geeignet sind und geringe Rad-­Schienen-Kräfte und geringen Rad-Schiene-Verschleiß aufweisen.The aim of the invention is to create drives which can also be used for high speeds, e.g. over 160 km / h, are suitable and have low wheel-rail forces and low wheel-rail wear.

Unter Laufwerken sind sowohl die entsprechenden Teile eines Starrahmenfahrzeuges als auch die von Drehgestellen eines Drehgestellfahrzeuges zu verstehen. Im folgenden wird die Erfindung nur mehr am Beispiel von Drehgestellen erläutert.Undercarriages are understood to mean both the corresponding parts of a rigid frame vehicle and those of bogies of a bogie vehicle. In the following the invention will only be explained using the example of bogies.

Im allgemeinen sind Drehgestelle, die für hohe Geschwindigkeiten geeignet sind, mit Radsätzen ausgerüstet, die relativ steil mit dem Drehgestellrahmen, hauptsächlich in X-Richtung (Fahrtrichung), verbunden sind, um instabilen Lauf vermeiden zu können.In general, bogies that are suitable for high speeds are equipped with wheelsets that are relatively steeply connected to the bogie frame, mainly in the X direction (direction of travel), in order to avoid unstable running.

Diese Drehgestelle haben durch die relativ starre Anlenkung der Radsätze am Rahmen nicht die Möglichkeit der Radsätze, sich bei Fahrt im Bogen radial einzustellen. Aus diesem Grund sind einerseits die Kräfte zwischen Rad und Schiene und der Verschleiß zwischen Rad und Schiene höher als bei Drehgestellen, deren Radsätze nicht relativ steif, sondern längselastisch mit dem Drehgestellrahmen verbunden sind und die sich bei Bogenfahrt teilweise oder vollständig radial einstellen können.Due to the relatively rigid articulation of the wheel sets on the frame, these bogies do not have the possibility of the wheel sets adjusting themselves radially when traveling in an arc. For this reason, on the one hand, the forces between the wheel and the rail and the wear between the wheel and the rail are higher than with bogies, the wheelsets of which are not relatively stiff but are connected to the bogie frame in a longitudinally elastic manner and which can partially or completely adjust radially when traveling on bends.

Drehgestelle, die vorzugsweise geringe Kräfte und geringen Rad-Schiene-­Verschleiß auch bei Bogenfahrt aufweisen sollen, werden u.a. mit Radsätzen ausgerüstet, die relativ elastisch (weich) mit dem Drehgestellrahmen, vorzugsweise in X-Richtung (Fahrtrichtung), verbunden sind. Dadurch haben die Radsätze die Möglichkeit, sich bei Bogenfahrt radial einzustellen, wodurch die Kräfte zwischen Rad und Schiene sowie der Verschleiß zwischen Rad und Schiene vermindert werden.Bogies, which should preferably have low forces and low wheel-rail wear even when traveling through bends, are equipped, among other things, with wheel sets that are relatively elastically (softly) connected to the bogie frame, preferably in the X direction (direction of travel). This enables the wheel sets to adjust radially when traveling through bends, reducing the forces between the wheel and the rail and the wear between the wheel and the rail.

Derartige Drehgestelle mit längselastischen Radsätzen sind nicht oder nur mit Zusatzeinrichtungen für hohe Geschwindigkeiten von über 160 km/h geeignet.Such bogies with longitudinally elastic wheelsets are not suitable or only suitable with additional devices for high speeds of over 160 km / h.

Um mit derartigen Drehgestellen auch hohe Geschwindigkeiten realisieren zu können, gibt es z.B. hydraulische oder mechanische Koppelungen etc., die gewährleisten, daß sich die Radsätze nur gegensinnig verdrehen können. So sind z.B. aus der DE-AS 23 56 267 Laufwerke bekannt, bei denen die Radsätze durch Radlenker miteinander verbunden sind. Aus der DE 31 23 858 A1 sind Laufwerke bekannt, bei denen die Radsätze über Hydraulikzylinder gekoppelt sind, wodurch in beiden Fällen das Laufverhalten von Schienenfahrzeugen sowohl in der Geraden als auch im Bogen wesentlich verbessert wird.In order to be able to achieve high speeds with such bogies, there are e.g. hydraulic or mechanical couplings etc., which ensure that the wheel sets can only turn in opposite directions. For example, known from DE-AS 23 56 267 drives in which the wheel sets are connected to one another by wheel control arms. DE 31 23 858 A1 drives are known in which the wheel sets are coupled via hydraulic cylinders, whereby the running behavior of rail vehicles in both the straight line and the bend is significantly improved in both cases.

Aufgabe der Erfindung ist die Schaffung von Maßnahmen, mit deren Hilfe die Radsätze hydraulisch gekoppelt werden können, ohne Hydraulikzylinder im engeren Sinne zur Anwendung zu bringen.The object of the invention is to provide measures by means of which the wheel sets can be coupled hydraulically without using hydraulic cylinders in the narrower sense.

Diese Aufgabe wird erfindungsgemäß durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1 gelöst.This object is achieved by the measure according to the characterizing part of patent claim 1.

Durch die Maßnahme nach Anspruch 3 sind unterschiedliche Steifigkeiten zwischen Radsatz und Drehgestellrahmen beliebig einstellbar.By the measure of claim 3, different stiffnesses between the wheelset and bogie frame can be set as desired.

Ein weiterer Vorteil der Erfindung ergibt sich durch die Maßnahme nach Anspruch 4.Another advantage of the invention results from the measure according to claim 4.

Durch die Maßnahme nach dem kennzeichnenden Teil des Anspruches 5 besteht die Möglichkeit, die oben erwähnten Steifigkeiten auch während der Fahrt verändern zu können.The measure according to the characterizing part of claim 5 makes it possible to be able to change the stiffnesses mentioned above even while driving.

Weitere Vorteile ergeben sich durch die Maßnahmen nach dem kennzeichnenden Teil der Ansprüche 6 bis 10.Further advantages result from the measures according to the characterizing part of claims 6 to 10.

Nachfolgend wird die Erfindung anhand der Zeichnungen näher erläutert, in welchen drei Ausführungsbeispiele des erfindungsgemäßen Laufwerkes dargestellt sind.The invention will be described in more detail below with reference to the drawings explains in which three embodiments of the drive according to the invention are shown.

Die Ausführungsform des Laufwerkes nach den Fig. 1 - 4 besitzt ein Drehgestell 1, welches zwei in der Fahrtrichtung liegende Seitenwangen 2 aufweist, die in der Längsmitte durch einen Hauptträger 3 und zu beiden Seiten desselben durch je einen Bremsträger 4 verbunden sind. Mit den strichpunktierten Linien sind in Fig. 2 Radsatzachsen 5 angedeutet, welche an beiden Enden in je einem Radsatzlager gelagert sind, das in einem Radsatzlagergehäuse sitzt, welches zu beiden Seiten der Radsatzachse einen Radsatzführungszapfen 6 (Fig. 3) lagert, der in Fig. 1 durch lotrechte, strichpunktierte Linien angedeutet ist. Das Radsatzlagergehäuse ist in Fig. 3 mit 7 bezeichnet. Es besitzt eine Öffnung 8 zur Aufnahme eines Führgungstopfes 9, der zylindrisch ausgeführt mit einer Gleitbuchse 10 ausgekleidet ist, in die eine ringförmige Buchse 11 eingesetzt ist, die einen Außenring 12 und einen Innenring 13 und dazwischen ein einvulkanisiertes ringförmiges gummielastisches Element 14 besitzt, welches in der Fahrtrichtung gesehen einander diametral gegenüberliegenden Kammern 15, 16 besitzt, die mit einem flüssigen Medium ausgefüllt sind. Selbstverständlich kann anstelle eines flüssigen Mediums auch ein gasförmiges vorgesehen sein.The embodiment of the drive according to FIGS. 1-4 has a bogie 1, which has two side cheeks 2 lying in the direction of travel, which are connected in the longitudinal center by a main support 3 and on both sides thereof by a brake support 4. The dash-dotted lines in FIG. 2 indicate wheelset axles 5, which are mounted at both ends in a wheel set bearing, which is seated in a wheel set bearing housing, which has a wheel set guide pin 6 (FIG. 3) on both sides of the axle, which is supported in FIG. 1 is indicated by vertical, dash-dotted lines. The wheel set bearing housing is designated 7 in FIG. 3. It has an opening 8 for receiving a guide pot 9, which is cylindrical is lined with a sliding bush 10, into which an annular bush 11 is inserted, which has an outer ring 12 and an inner ring 13 and between them a vulcanized annular rubber-elastic element 14, which, viewed in the direction of travel, has diametrically opposite chambers 15, 16 which are filled with a liquid medium. Of course, a gaseous medium can also be provided instead of a liquid medium.

Um das Ausbrechen des gummielastischen Elementes 14 im Bereiche der Kammern 15, 16 nach oben oder unten zu verhindern, ist das genannte Element 14 am oberen Ende durch einen Bund 71 des Radsatzführungs­zapfens 6 und an seinem unteren Ende durch eine Scheibe 72 geschützt, welche durch den Bund 73 einer Stange 74 gegen den Innenring 13 der Buchse 11 gedrückt wird, wobei die Stange 74 mit einem Gewindeende 75 im Radsatzführungszapfen 6 eingeschraubt ist.In order to prevent the rubber-elastic element 14 from breaking out in the areas of the chambers 15, 16 upwards or downwards, said element 14 is protected at the upper end by a collar 71 of the wheel set guide pin 6 and at its lower end by a disk 72 which is protected by the Collar 73 of a rod 74 is pressed against the inner ring 13 of the bushing 11, the rod 74 being screwed into the wheel set guide pin 6 with a threaded end 75.

Zur Abdichtung des Systems ist ein Balg 36 vorgesehen, welcher an seinem unteren Ende durch einen Klemmring 37 an einer Buchse 38 befestigt ist, die in das obere Ende des Führungstopfes 9 eingesetzt ist. Das obere Ende des Balges 36 ist an einem offenen, seitlich abstehenden Boden 39 eines Topfes 40 angeschlossen, der zum Schutz des Balges 36 gegen Steinschlag usw. dient. Der Topf 40 ist mit seinem ausragenden Rand des Bodens 39 zwischen einer Schraubenfeder 41 und einem Gummiring 54 des Drehgestellrahmens bzw. der Seitenwange 2 desselben eingespannt. Die Schraubenfeder 41 dient zur vollen Aufnahme der vertikalen Führungskräfte und sitzt an ihrem unteren Ende auf einem von Führungstopf 9 abstehenden Bund 42 auf, mit welchem sich der Führungstopf 9 über eine Beilage 43 am Radsatzlagergehäuse 7 abstützt. Am oberen Ende stützt sich die Feder 41 am ausragenden Teil des Bodens 39 des Topfes 40 ab.To seal the system, a bellows 36 is provided, which is attached at its lower end by a clamping ring 37 to a bush 38 which is inserted into the upper end of the guide pot 9. The upper end of the bellows 36 is connected to an open, laterally projecting bottom 39 of a pot 40, which serves to protect the bellows 36 against stone chips, etc. The pot 40 is clamped with its protruding edge of the bottom 39 between a helical spring 41 and a rubber ring 54 of the bogie frame or the side cheek 2 of the same. The helical spring 41 serves to fully accommodate the vertical executives and is seated at its lower end on a collar 42 protruding from the guide pot 9, with which the guide pot 9 is supported on the wheel set bearing housing 7 via an insert 43. At the upper end, the spring 41 is supported on the protruding part of the bottom 39 of the pot 40.

In beide Kammern 15, 16 mündet vorzugsweise nahe dem Boden derselben je eine Öffnung 76 bzw. 77, an welche eine Leitung 78 bzw. 79 anschließt. Wie in Fig. 2 dargestellt, sind beispielsweise lediglich die außenliegenden Buchsen 11₁-11₄ mit dem Hydrauliksystem ausgestattet. Hiebei ist jeweils die linke Kammer 15 einer Buchse 11 mit der rechten Kammer 16 der diagonal gegenüberliegenden Buchse durch die Leitung 78 verbunden. Ähnlich ist die rechte Kammer 16 jeder Buchse 11 mit der linken Kammer 15 der diagonal gegenüberliegenden Buchse 11 durch die Leitung 79 verbunden. In diesen Leitungen kann ein Drosselventil, ein Absperrventil oder ein Absperrdrossenventil 80 vor­gesehen sein. Diese Steuerung ermöglicht eine gegenläufige Sinusbewegung der Radsätze. Wird beispielsweise bei der Buchse 11₁ die äußere oder linke Kammer 15 zusammengedrückt, strömt das flüssige Medium über die Leitung 78 in die äußere oder rechte Kammer 16 der diagonal gegenüberliegenden Buchse 11₃ usw., wie aus Fig. 2 ersichtlich ist.In both chambers 15, 16 preferably an opening 76 or 77 opens near the bottom thereof, to which a line 78 or 79 connects. As shown in Fig. 2, for example, are merely the external bushings 11₁-11₄ equipped with the hydraulic system. The left chamber 15 of a socket 11 is connected to the right chamber 16 of the diagonally opposite socket by line 78. Similarly, the right chamber 16 of each socket 11 is connected to the left chamber 15 of the diagonally opposed socket 11 through the conduit 79. A throttle valve, a shut-off valve or a shut-off throttle valve 80 can be provided in these lines. This control enables the wheelsets to rotate in opposite directions. For example, if the outer or left chamber 15 is compressed in the socket 11 1, the liquid medium flows via the line 78 into the outer or right chamber 16 of the diagonally opposite socket 11 3, etc., as can be seen from FIG. 2.

Selbstverständlich können auch die innenliegenden Buchsen mit dem Hydrauliksystem ausgestattet sein, wobei die betreffenden Kammern je nach Bedarf miteinander verbunden sind.Of course, the inner bushings can also be equipped with the hydraulic system, the chambers in question being connected to one another as required.

Im Rahmen der Erfindung können beliebige Kammern beliebiger Buchsen durch beliebige Kammern beliebiger anderer Buchsen hydraulisch oder pneumatisch im Sinne der vorliegenden Erfindung verbunden werden.In the context of the invention, any chambers of any bushes can be hydraulically or pneumatically connected by any chambers of any other bushings in the sense of the present invention.

Die Verbindung der Kammern verschiedener Buchsen dient vorzugsweise dazu, um gegensinnige Drehbewegung der Radsatzachsen um ihre Hochachse zuzulassen. Die Verbindung dieser Kammern kann jedoch je nach Bedarf beliebig, z.B. kreuzweise, parallel od. dgl. erfolgen. So liegt es im Rahmen der Erfindung, die Kammern der außen liegenden Buchsen mit Kammern innen liegender Buchsen der gleichen oder gegenüberliegenden Seitenwange 2 und umgekehrt zu verbinden.The connection of the chambers of different bushings is preferably used to allow the axles to rotate in opposite directions about their vertical axis. However, the connection of these chambers can be made as required, e.g. crosswise, parallel or the like. Thus, it is within the scope of the invention to connect the chambers of the outer bushes with chambers of inner bushes of the same or opposite side cheek 2 and vice versa.

Bei Verwendung von Buchsen nach Fig. 5 entfallen die Leitungen 78, 79 und zwangsläufig auch die Öffnungen 76 und 77. Bei diesen Buchsen sind die Kammern 15, 16 durch einen Kanal 81 verbunden, wobei allenfalls auch an der diametral gegenüberliegenden Seite allenfalls ein der­artiger Kanal vorgesehen sein kann. In diesem Falle strömt durch einge­leitete Kraft das flüssige Medium aus der durch diese Kraft zusammen­ gedrückten Kammer über den genannten Kanal in die Gegenkammer, wodurch eine relativ hohe Dämpfung der Verformung der Buchse erreicht wird.5, the lines 78, 79 and inevitably also the openings 76 and 77 are omitted. In these sockets, the chambers 15, 16 are connected by a channel 81, with such a channel possibly also on the diametrically opposite side can be provided. In this case, the liquid medium flows together from the force introduced by this force pressed chamber via the channel mentioned in the counter chamber, whereby a relatively high damping of the deformation of the socket is achieved.

Bei der Ausführungsform der Buchse nach den Fig. 6 bis 9 sind die Kammern 15,16 bzw. deren Öffnungen 76,77 wobei lediglich die Öffnung 76 der Kammer 15 sichtbar ist, durch einen Überströmkanal 84 miteinander verbunden, welcher im vorliegenden Fall in einer Steuerschaltvorrichtung 80 ausgebildet ist, wobei die Kammern 15,16, der Überströmkanal 84 sowie allenfalls ausgebildete Nebenräume 86 einen nach außen hin abgedichteten, geschlossenen Raum bilden. Zwischen den Kammern 15,16 befinden sich Segmente 82 bzw. 83 mit einvulkanisierten Blechen 65 bzw. 66.In the embodiment of the bushing according to FIGS. 6 to 9, the chambers 15, 16 or their openings 76, 77, with only the opening 76 of the chamber 15 being visible, are connected to one another by an overflow channel 84, which in the present case is in a control switching device 80 is formed, with the chambers 15, 16, the overflow channel 84 and any additional spaces 86 formed forming a closed space which is sealed off from the outside. Between the chambers 15, 16 there are segments 82 and 83 with vulcanized sheets 65 and 66, respectively.

Somit können insbesondere radiale Relativ-Bewegungen von Außenhülse 12 und Innenhülse 13 in Richtung der ausgebildeten, einander gegenüberliegenden Kammern 15 und 16 ohne wesentliche Beeinflussung durch das Fluid oder das gasförmige Medium vonstatten gehen.Thus, in particular radial relative movements of the outer sleeve 12 and inner sleeve 13 in the direction of the formed, opposing chambers 15 and 16 can take place without substantial influence by the fluid or the gaseous medium.

Das verdrängte Volumen der einen Kammer, z.B. 15, strömt über den Überströmkanal 81 relativ ungehindert in die gegenüberliegende Kammer 16. Somit ist die Steifigkeit, die dieser radialen Bewegung entgegenwirkt, hauptsächlich abhängig von der Ausbildung der im gummielastischen Element 14 ausgebildeten Segmente 82 und 83.The displaced volume of one chamber, e.g. 15, flows over the overflow channel 81 into the opposite chamber 16 relatively unhindered. Thus, the rigidity which counteracts this radial movement is primarily dependent on the design of the segments 82 and 83 formed in the rubber-elastic element 14.

In der Schaltvorrichtung 80 ist vorzugsweise eine Zusatzeinrichtung 87 ausgeführt, mit der der Überströmkanal 81 vollständig oder teilweise versperrt werden kann. Als Ausführungsbeispiel ist in den Figuren 4 und 5 ein Regelkolben 87a mit einer Feder 87b und einem Elektromagnet 87c dargestellt.An additional device 87 is preferably implemented in the switching device 80, with which the overflow channel 81 can be completely or partially blocked. As an exemplary embodiment, a control piston 87a with a spring 87b and an electromagnet 87c is shown in FIGS. 4 and 5.

Wird nun der Überströmkanal 84 durch diese Zusatzeinrichtung 87 ganz oder teilweise verschlossen, kann das bei vorzugsweise radialen Relativbewegungen der Außenhülse 12 zu der Innenhülse 13 verdrängte Volumen, nur mehr stark beeinflußt vom nun verengten Querschnitt des Überströmkanals 81, von einer Kammer zur anderen strömen, oder aber der Überströmvorgang wird durch totalen Verschluß des Überströmkanals 81 überhaupt verhindert.If the overflow channel 84 is completely or partially closed by this additional device 87, the volume displaced in the case of preferably radial relative movements of the outer sleeve 12 relative to the inner sleeve 13 can only flow from one chamber to another, strongly influenced by the now narrowed cross section of the overflow channel 81, or but the overflow process is prevented by a total closure of the overflow channel 81.

Somit ist die Steifigkeit, die dieser radialen Bewegung entgegenwirkt, nicht mehr hauptsächlich nur von der Ausbildung der Gummisegmente 82 und 83 abhängig. Vielmehr wird nun über das Fluid oder das gasförmige Medium in den Kammern 15 und 16, das nun nicht mehr relativ störungsfrei in die jeweils andere Kammer strömen kann, Druck auf das restliche ausgeformte gummielastische Element 14 ausgeübt und dadurch die Steifigkeit, die der Relativbewegung der Buchsenaußenhülse zur Buchseninnenhülse 13 entgegenwirkt, maßgeblich beeinflußt.The rigidity which counteracts this radial movement is therefore no longer primarily dependent only on the design of the rubber segments 82 and 83. Rather, the fluid or the gaseous medium in the chambers 15 and 16, which can no longer flow relatively smoothly into the other chamber, is now exerting pressure on the remaining molded rubber-elastic element 14 and thereby the stiffness corresponding to the relative movement of the outer sleeve counteracts the inner sleeve 13, significantly influenced.

Durch geeignete Ausbildung des beschriebenen Elementes 85 ist es nun auch gemäß der Erfindung möglich, unterschliedliche Steifigkeiten zwischen Radsatz und Drehgestellrahmen beliebig einstellbar zu realisieren.By a suitable design of the element 85 described, it is now also possible according to the invention to implement different stiffnesses between the wheel set and the bogie frame which can be set as desired.

Diese Steifigkeiten können auch während der Fahrt, z.B. in Abhängigkeit von der Geschwindigkeit, verändert werden.These stiffnesses can also be found while driving, e.g. depending on the speed.

Weiters ist es möglich, durch Einstellung eines bestimmten Querschnittes des Überströmkanals 84 durch die Schaltvorrichtung 80 die Steifigkeiten und vor allem auch das Dämpfungsverhalten beliebig einzustellen.Furthermore, it is possible to set the stiffnesses and, above all, the damping behavior as desired by setting a specific cross section of the overflow channel 84 through the switching device 80.

Auch ist es möglich, den Regelmechanismus, der durch die Funktionen der Zusatzeinrichtung 87 gewährleistet wird, auch durch eine anders ausgebildete einstellbare Zusatzeinheit, z.B. eine schaltbare Drossel, zu ersetzen.It is also possible to regulate the control mechanism, which is ensured by the functions of the additional device 87, by a differently configured adjustable additional unit, e.g. a switchable choke to replace.

Selbstverständlich können im Rahmen der Erfindung weitere konstruktive Änderungen des Erfindungsgegenstandes vorgenommen werden. So besteht die Möglichkeit, die Buchsen auch ohne ein elastisches Gummielement auszustatten und lediglich eine mit Flüssigkeit oder Gas gefüllte Kammer vorzusehen, deren Volumen z.B. durch Zusammendrücken der Kammerwände veränderbar ist.Of course, further constructive changes to the subject of the invention can be made within the scope of the invention. So it is possible to equip the bushings without an elastic rubber element and to provide only one chamber filled with liquid or gas, the volume of which e.g. can be changed by compressing the chamber walls.
