Description

Die Erfindung betrifft ein Fahrwerk nach dem Oberbegriff des Patentanspruchs 1 und ein Schienenfahrzeug mit mindestens einem derartigen Fahrwerk.The invention relates to a chassis according to the preamble of patent claim 1 and a rail vehicle with at least one such chassis.

Ein aus EP-A-0 649 782 bekanntes Fahrwerk der genannten Art enthält zwei Radsätze und zwei zwischen deren Rädern je auf einer der Radsatzachsen gelagerte Führungsteile, welche miteinander um eine Hochachse schwenkbar gekoppelt sind, wobei mindestens einer der Führungsteile über eine Führungsanordnung mit dem Fahrzeugkasten in Querrichtung beweglich koppelbar ist. Das bekannte Fahrwerk ist als rahmenlose Traganordnung für den Fahrzeugkasten ausgebildet, der über seitlich auslenkbare Federelemente auf an den Enden der Radsatzachsen angeordneten Achslagern abgestützt ist. Diese Anordnung gestattet bei Kurvenfahrt eine selbsttätige, zumindest annähernd radiale Einstellung der Radsatzachsen bezüglich eines jeweils zu durchfahrenden Gleisbogens. Das bekannte Fahrwerk kann als Triebfahrwerk oder als Lauffahrwerk ausgeführt sein, wobei bei einem Triebfahrwerk die Führungsteile je durch ein Gehäuse einer Antriebseinrichtung gebildet sein können, welches über Tatzlager auf der betreffenden Radsatzachse gelagert ist. Die bekannte Ausführung gestattet eine relativ kompakte Bauweise des Fahrwerks mit einem minimalen Abstand zwischen den Radsätzen und einer grossen Verwindungsweichheit der Radsatzachsen, wodurch im wesentlichen ausgeglichene Radlasten, z.B. beim Befahren von Gleisverwindungen, erzielbar sind.A known from EP-A-0 649 782 suspension of the type mentioned includes two sets of wheels and two between the wheels each mounted on one of the wheelsets guide parts which are pivotally coupled to each other about a vertical axis, wherein at least one of the guide parts via a guide assembly with the vehicle body in the transverse direction is movable coupled. The known suspension is designed as a frameless support arrangement for the vehicle body, which is supported on laterally deflectable spring elements arranged on the ends of the wheelset axle bearings. This arrangement allows for cornering an automatic, at least approximately radial adjustment of the wheelset with respect to a respective track to be traversed. The known suspension can be designed as a power train or as a running gear, wherein in a traction drive, the guide parts can be formed by a housing of a drive device depending on which Tatzlager is mounted on the relevant wheelset axle. The known design allows a relatively compact design of the chassis with a minimum distance between the wheelsets and a large torsional softness of the axles, whereby substantially balanced wheel loads, eg when driving on track distortions, can be achieved.

Aus der EP 0 165 752 A2 ist ein gattungsgemäßes Fahrwerk bekannt, bei dem der Fahrzeugkasten über zwei seitlich am Fahrwerk angeordnete, die Spurweite des Fahrzeugs seitlich überragende Federanordnungen auf dem Fahrwerk abgestützt ist. Die Federanordnungen befinden sich dabei auf einer Traverse, die beweglich auf seitlichen Rahmenteilen des Fahrwerks aufliegt. Die Bewegung zwischen der Traverse und den Rahmenteilen ist durch entsprechende Lenker mit elastischen Anlenkpunkten stark eingeschränkt.From EP 0 165 752 A2 a generic chassis is known in which the vehicle body is supported on the chassis by means of two laterally arranged on the chassis, the track width of the vehicle laterally projecting spring arrangements. The spring assemblies are located on a traverse, which rests movably on lateral frame parts of the chassis. The movement between the traverse and the frame parts is severely limited by corresponding link with elastic articulation points.

Diese Konfiguration weist zum einen den Nachteil auf, dass sie wenig kompakt und vergleichsweise aufwändig gestaltet ist. Zudem ermöglicht sie in der Horizontalebene in Folge hoher Rückstellkräfte, insbesondere durch die beiden Federanordnungen, nur relativ eingeschränkte Bewegungen zwischen dem Fahrwerk und dem Fahrzeugkasten. Dies ist gerade bei extrem engen Kurvenradien, die für eine optimale Einstellung der Radsatzachsen eine starke relative Verdrehung zwischen Fahrwerk und Fahrzeugkasten erfordern, von Nachteil.This configuration has the disadvantage that it is not very compact and comparatively expensive. In addition, it allows in the horizontal plane as a result of high restoring forces, in particular by the two spring arrangements, only relatively limited movements between the chassis and the vehicle body. This is especially at extremely tight curve radii, which require a strong relative rotation between the chassis and vehicle body for optimum adjustment of the axles, disadvantageous.

Der Erfindung liegt die Aufgabe zugrunde, ein weiter entwickeltes Fahrwerk der eingangs genannten Art zu schaffen, welches mit geringerem Aufwand und in einer leichteren, kompakteren Bauweise als bisherige Ausführungen hergestellt werden kann und welches auch auf Gleisanlagen und Schienennetzen mit extrem engen Kurvenradien, wie sie etwa bei Strassenbahnen auftreten, eine annähernd radiale Einstellung der Radsatzachsen bezüglich der zu durchfahrenden Gleiskurven gewährleistet.The invention has for its object to provide a further developed suspension of the type mentioned, which can be made with less effort and in a lighter, more compact design than previous versions and which also on track systems and rail networks with extremely tight curve radii, such as occur in trams, ensuring an approximately radial adjustment of the wheelset with respect to the track curves to be traveled.

Diese Aufgabe wird erfindungsgemäss mit einem Fahrwerk gelöst, welches die Merkmale im kennzeichnenden Teil des unabhängigen Patentanspruchs 1 aufweist. Ein Schienenfahrzeug mit mindestens einem derartigen Fahrwerk ist Gegenstand des unabhängigen Anspruchs 13. Ausgestaltungen des Erfindungsgegenstandes sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with a chassis, which has the features in the characterizing part of independent claim 1. A rail vehicle with at least one such chassis is the subject of independent claim 13. Embodiments of the subject invention are specified in the dependent claims.

Die erfindungsgemässe Ausführung des Fahrwerks ergibt eine gegenüber bisherigen Ausführungen wesentlich kompaktere Bauweise, welche sich insbesondere durch vorteilhaft geringe Abmessungen des Fahrwerks in Fahrzeugquerrichtung auszeichnet und welche die Anordnung aller tragenden und/oder lärmabstrahlenden Bauteile innerhalb eines durch die Spurweite der Radsätze gegebenen Einbauraums gestattet. Das erfindungsgemäss ausgebildete Fahrwerk erfordert somit keine ausserhalb der Radscheiben der Radsätze angeordneten Lagerteile und Bremseinheiten und kann auch im Falle extremer Auslenkungen der Radsätze beim Durchfahren enger Kurven, etwa solchen mit einem Kurvenradius von weniger als 20 m, z.B. 17 m, innerhalb des Grundrisses und damit innerhalb der Umrandung des Fahrzeugkastens gehalten werden. Entsprechend kann die Aussenhaut der Kastenstruktur vorteilhaft tief, z.B. bis auf die Höhe der Radsatzachsen nach unten verlängert und damit ein wesentlich verbessertes Lärmverhalten des Schienenfahrzeugs erzielt werden.The inventive design of the chassis results in a much more compact compared to previous designs construction, which is characterized in particular by advantageously small dimensions of the chassis in the vehicle transverse direction and which allows the arrangement of all supporting and / or Lärmabstrahlenden components within a given by the track of the wheelsets installation space. The invention designed according to the chassis thus requires no outside the wheel discs of the wheelsets arranged bearing parts and brake units and can be maintained even in the case of extreme deflections of the wheelsets when driving through tight curves, such as those with a radius of curvature of less than 20 m, for example 17 m, within the floor plan and thus within the border of the vehicle body. Correspondingly, the outer skin of the box structure can advantageously be extended downwards, for example down to the height of the wheelset axles, and thus a significantly improved noise behavior of the rail vehicle can be achieved.

Die Führungsvorrichtungen 10 sind ferner über Halteeinrichtungen, darstellungsgemäss über je eine Pendelstütze 12, in Fahrzeug-Längs- und Querrichtung beweglich am Fahrzeugkasten 6 aufgehängt bzw. gegen diesen abgestützt. Mindestens eine der Führungsvorrichtungen 10, darstellungsgemäss diejenige des Radsatzes 2, ist mit dem Fahrzeugkasten 6 über eine Vorrichtung 13 zum Uebertragen von Zug- und Bremskräften gekoppelt.The chassis 1 according to FIGS. 1 and 2, according to the illustration a traction chassis, contains a bogie frame 4 supported on two sets of wheels 2 and 3, on which a vehicle body 6 is supported via a central spring arrangement 5. The wheelsets 2 and 3, which each have a wheelset 7 and two rotatably connected wheels 8, are coupled via two each mounted between the wheels 8 on one of the wheelsets 7 guide devices 10 and a coupling device 11 to each other about a vertical axis H pivotally. The guide devices 10 are also suspended on holding means, according to the representation via a respective pendulum support 12 in the vehicle longitudinal and transverse direction on the vehicle body 6 and supported against it. At least one of the guide devices 10, according to the representation of that of the wheel set 2, is coupled to the vehicle body 6 via a device 13 for transmitting tensile and braking forces.

Die Radsätze 2 und 3 sind je mit einem Antriebsmotor 14 versehen, der über ein Stirnradgetriebe 15 mit der betreffenden Radsatzachse 7 getrieblich verbunden ist. Die Führungsvorrichtungen 10 sind je durch die miteinander verbundenen Gehäuse des Antriebsmotors 14 und des Stirnradgetriebes 15 gebildet, welche über Tatzlageranordnungen mit einem auf der betreffenden Radsatzachse 7 gelagerten Tragrohr 16 zu einer starren Baueinheit verbunden sind. Die Pendelstützen 12 sind als Wankstützen für den Fahrzeugkasten 6 ausgebildet und in Fahrzeug-Längs- und Querrichtung gegeneinander versetzt an den Führungsvorrichtungen 10 sowie je an einer am Fahrzeugkasten 6 vorgesehenen Anlenkstelle 9 raumbeweglich, darstellungsgemäss über elastische Zwischenstücke 19 aus einem gummiartigen Material, schwenkbar angelenkt. Entsprechend können Wankbewegungen des Fahrzeugkastens 6 um eine Längsachse eingeschränkt werden.The wheelsets 2 and 3 are each provided with a drive motor 14, which is connected via a spur gear 15 with the respective wheelset axle 7 geared. The guide devices 10 are each formed by the interconnected housing of the drive motor 14 and the spur gear 15, which are connected via Tatzlageranordnungen with a mounted on the wheelset axle 7 supporting tube 16 to a rigid assembly. The pendulum supports 12 are formed as roll supports for the vehicle body 6 and offset in the vehicle longitudinal and transverse directions against each other on the guide devices 10 and one at each on Vehicle box 6 provided articulation point 9 spatially movable, according to the representation via elastic spacers 19 made of a rubber-like material, hinged. Accordingly, rolling movements of the vehicle body 6 about a longitudinal axis can be restricted.

Die Koppelvorrichtung 11 enthält zwei je von einer der Führungsvorrichtungen 10 in Fahrwerklängsrichtung gegen die Quermittelebene E des Fahrwerks 1 abstehende, deichselartige Anschlussteile 17 bzw. 18, welche in der Fahrwerk- bzw. Drehgestellmitte raumbeweglich schwenkbar miteinander gelenkig verbunden sind. Entsprechend sind die Führungsvorrichtungen 10 miteinander gegensinnig auslenkbar gekoppelt, wobei die Radsatzachsen 7 je im wesentlichen radial zu einem jeweils zu durchfahrenden Gleisbogen einstellbar sind. Die Anschlussteile 17 und 18 können darstellungsgemäss über ein Kugelgelenk 20 oder, nach einer anderen Ausführung, in einer einfacheren Gelenkanordnung über elastische Zwischenstücke aus einem gummiartigen Material zusammenwirken.The coupling device 11 includes two each of one of the guide devices 10 in the longitudinal direction of the chassis against the transverse center plane E of the chassis 1 projecting, drawbar-like connection parts 17 and 18, which are pivotally connected to each other in the chassis or bogie center pivotally articulated. Correspondingly, the guide devices 10 are coupled to each other in an oppositely deflectable manner, the wheelset axles 7 each being adjustable substantially radially relative to a track curve to be traveled through in each case. The connecting parts 17 and 18 can act according to the representation of a ball joint 20 or, according to another embodiment, in a simpler joint arrangement via elastic spacers made of a rubber-like material.

Die Vorrichtung 13 zum Uebertragen von Zug- und Bremskräften enthält eine gegenüber dem Radsatz 2 in Fahrzeuglängsrichtung versetzt positionierbare Traverse 21 in Form eines Dreiecklenkers, der mit einem gegen den Radsatz 2 weisenden Verbindungsteil 22 an einem am Tragrohr 16 nach unten abstehend angebrachten Zapfen 23 raumbeweglich angelenkt ist, und zwei an den Enden der Traverse 21 anlenkbare, gegen den Radsatz 2 orientierbare Lenkhebel 24. Die freien Enden der Lenkhebel 24 sind zum Anlenken an zwei dem Radsatz 2 benachbarten Mitnehmerzapfen 25 bestimmt, welche je an einer nach unten vorstehenden Anschlusspartie des Fahrzeugkastens 6 angebracht sind, wobei der Abstand zwischen diesen Mitnehmerzapfen 25 grösser ist als der Abstand zwischen den Anlenkstellen der Lenkhebel 24 an der Traverse 21. Die Anordnung der Mitnehmerzapfen 25 und der Lenkhebel 24 kann dabei so gewählt werden, dass sich für das Fahrwerk 1 in der Fahrwerkmitte, im Bereich der Hochachse H, ein virtueller Drehpunkt ergibt, der gegenüber dem Fahrzeugkasten 6 keine Längsverschiebung ausführt. Ein wesentlicher Vorteil der beschriebenen Vorrichtung 13 besteht darin, dass sie ausserhalb des Fahrwerks 1 in einem gut zugänglichen Bereich des Fahrzeuges angeordnet werden kann, in dem ein ausreichender Einbauraum zur Verfügung steht und eine für die Einleitung der Traktionskräfte günstige Anbringung am Fahrzeugkasten 6 möglich ist.The device 13 for transmitting tensile and braking forces includes a relative to the wheelset 2 in the vehicle longitudinally positionable Traverse 21 in the form of a wishbone articulated with a facing the wheel set 2 connecting part 22 on a support tube 16 projecting downwardly mounted pin 23 spatially movable is, and two at the ends of the crossbar 21 articulated, against the wheelset 2 orientable steering lever 24. The free ends of the steering lever 24 are intended for articulation on two wheelset 2 adjacent driving pin 25, which depending on a downwardly projecting connecting portion of the vehicle body. 6 are attached, wherein the distance between these driving pin 25 is greater than the distance between The arrangement of the driving pin 25 and the steering lever 24 can be chosen so that there is a virtual fulcrum for the chassis 1 in the center of the chassis, in the region of the vertical axis H, compared to the vehicle body 6 performs no longitudinal displacement. A significant advantage of the described device 13 is that it can be arranged outside the chassis 1 in an easily accessible area of the vehicle, in which a sufficient installation space is available and a favorable for the introduction of traction forces attachment to the vehicle body 6 is possible.

Der vom Gewicht der Antriebseinrichtungen entlastete Drehgestellrahmen 4 kann in einer besonders einfachen, leichten Bauweise, darstellungsgemäss als H-förmige Tragkonstruktion, ausgeführt werden, welche zwei innerhalb der Spurweite der Radsätze 2 und 3 angeordnete Längsträger 26 und einen diese verbindenden mittigen Querträger 27 aufweist. Die Längsträger 26 sind mit ihren Enden über je zumindest in Fahrwerk-Längsrichtung nachgiebige Federelemente 28, darstellungsgemäss Gummischichtfedern, auf je zwischen den Rädern 8 des betreffenden Radsatzes 2 bzw. 3 angeordneten inneren Stützteilen des Fahrwerks 1, bei der dargestellten Ausführung auf an den Gehäuseteilen der Führungsvorrichtungen 10 angeordneten Konsolen 30, abgestützt. Entsprechend ist eine besonders einfache, raumsparende Stützanordnung erzielbar, über welche die Tragkonstruktion ohne zusätzliche Achslager auf den Radsatzachsen 7 abgestützt werden kann. Die Federanordnung 5 zum Abstützen des Fahrzeugkastens 6 ist im zentralen Bereich des Fahrwerks 1 auf einer am Querträger 27 ausgebildeten Tragpartie 31 angebracht. Die Längsträger 26 und der Querträger 27 sind darstellungsgemäss je mit einem verwindungssteifen, kastenförmigen Querschnitt ausgeführt. Nach einer anderen, nicht dargestellten Ausführungsform kann auch ein entsprechender Querträger 27 mit einem T-förmigen Querschnitt vorgesehen sein, der eine verwindungsweiche Verbindung zwischen den Längsträgern 26 zulässt. Anstelle der dargestellten H-förmigen Tragkonstruktion kann auch ein geschlossener Rahmen vorgesehen sein.The weight of the drive means relieved bogie frame 4 can be in a particularly simple, lightweight construction, according to the representation as H-shaped support structure, running, which has two arranged within the track of the wheelsets 2 and 3 longitudinal beams 26 and connecting them central cross member 27. The longitudinal beams 26 are with their ends on each at least in the chassis longitudinally resilient spring elements 28, according to the illustration Gummischichtfedern on each between the wheels 8 of the respective wheelset 2 and 3 arranged inner support parts of the chassis 1, in the illustrated embodiment on the housing parts of Guide devices 10 arranged brackets 30, supported. Accordingly, a particularly simple, space-saving support arrangement can be achieved, via which the support structure can be supported without additional axle bearings on the wheelset 7. The spring assembly 5 for supporting the vehicle body 6 is mounted in the central region of the chassis 1 on a support member 31 formed on the cross member 27. The side members 26 and the cross member 27 are according to the representation, each with a torsionally stiff, box-shaped cross-section. According to another, not shown embodiment, a corresponding cross member 27 may be provided with a T-shaped cross section, which allows a torsionally soft connection between the longitudinal members 26. Instead of the illustrated H-shaped support structure may also be provided a closed frame.

Wie insbesondere aus der Fig.3 hervorgeht, enthält die Federanordnung 5 eine Stützplatte 19 und eine Luftfeder 32, die über einen Tragring 33, ein Stützelement 34 in Form einer ringförmigen Gummischichtfeder und ein Axiallager 35 auf der Tragpartie 31 des Querträgers 27 um die Hochachse H drehbar abgestützt ist. Diese zentrale, drehbar gelagerte Federanordnung 5 gestattet relativ grosse, weitgehend unbehinderte Ausdrehbewegungen des Fahrwerks 1 relativ zum Fahrzeugkasten 6 um die Hochachse H, wobei auf das Fahrwerk 1 nur vorteilhaft geringe Rückstellkräfte einwirken. Die Luftfeder 32 wird im wesentlichen nur durch vertikale Stützkräfte und gegebenenfalls Querkräfte belastet, da nachteilige Beanspruchungen der Luftfeder 32 durch Torsionskräfte vermieden werden können.As is apparent in particular from Figure 3, the spring assembly 5 includes a support plate 19 and an air spring 32 via a support ring 33, a support member 34 in the form of an annular rubber layer spring and a thrust bearing 35 on the support portion 31 of the cross member 27 about the vertical axis H. is rotatably supported. This central, rotatably mounted spring assembly 5 allows relatively large, largely unobstructed Ausdrehbewegungen of the chassis 1 relative to the vehicle body 6 about the vertical axis H, acting on the chassis 1 only advantageously low restoring forces. The air spring 32 is essentially loaded only by vertical support forces and possibly transverse forces, since adverse stresses on the air spring 32 can be avoided by torsional forces.

Durch die vollständig innerhalb der Spurweite der Radsätze 2 und 3 angeordnete Tragkonstruktion für den Fahrzeugkasten 6 ist eine besonders kompakte Bauweise des Fahrwerks 1 erzielbar, bei der ausserhalb der Radscheiben weder Trag- und/oder Lagerteile noch Teile der Bremsanlage angeordnet sind. Entsprechend der Darstellung nach den Fig.1 und 2 können zwischen den Radsätzen 2 und 3 zwei je in einem geringen Abstand oberhalb der Schienenoberkanten S angeordnete Magnetschienenbremsen 36 vorgesehen sein, welche je über Haltestangen 37 an zwei Konsolen 38 befestigt sind, die je an der Aussenseite des betreffenden Längsträgers 26 angebracht sind. Die Radsätze 2 und 3 können ferner je mit einer innerhalb der Spurweite angeordneten Getriebebremse in Form eines an der betreffenden Führungsvorrichtung 10 anbringbaren Bremsaggregats 40 versehen sein, welches zum Zusammenwirken mit einer Bremsscheibe 41 bestimmt ist, die darstellungsgemäss auf einer aus dem Gehäuse des Stirnradgetriebes 15 vorstehenden Ritzelwelle 42 des Antriebsmotors 14 angebracht ist. Die beschriebene Anordnung ermöglicht einen einfachen Ein- und Ausbau der Antriebseinrichtung. Die Motor-/Getriebeeinheiten können z.B. zusammen mit der Motorscheibenbreme nach unten ausgebaut werden.Due to the completely arranged within the track of the wheelsets 2 and 3 support structure for the vehicle body 6 is a particularly compact design of the chassis 1 can be achieved in the outside of the wheel discs neither support and / or bearing parts nor parts of the brake system are arranged. As shown in FIGS. 1 and 2, two magnetic rail brakes 36, each located at a small distance above the rail upper edges S, may be provided between the wheel sets 2 and 3, which are each fastened via holding rods 37 to two brackets 38 each on the outside of relevant longitudinal member 26 are mounted. The wheelsets 2 and 3 may also each be provided with an arranged within the track transmission brake in the form of an attachable to the respective guide device 10 brake unit 40, which is intended to cooperate with a brake disk 41, the representation according to a protruding from the housing 15 of the spur gear Pinion shaft 42 of the drive motor 14 is mounted. The arrangement described allows easy installation and removal of the drive device. For example, the engine / transmission units can be removed downwards together with the engine disk brakes.

Die zwischen dem Drehgestellrahmen 4 und den Führungsvorrichtungen 10 angeordneten Federelemente 28 ergeben eine in vertikaler Richtung relativ harte, in Fahrwerk-Längs- und Querrichtung nachgiebige Primärfederung, welche Relativbewegungen der Radsätze 2 und 3 gegenüber dem Drehgestellrahmen 4 im Sinne einer zumindest annähernd radialen Einstellung der Radsatzachsen 7 beim Durchfahren eines Gleisbogens sowie, beim Ausfahren aus dem Gleisbogen, aufgrund der Rückstellkraft der elastisch verformten Federelemente 28, eine Rückführung der Radsatzachsen 7 je in eine zueinander parallele Normalstellung gestattet. Dabei ist eine günstige Beanspruchung der Federelemente 28 erzielbar, welche entsprechende Auslenkungen vorwiegend in Längsrichtung, und nur relativ geringe Auslenkungen in Querrichtung erfahren.The arranged between the bogie frame 4 and the guide devices 10 spring elements 28 result in a relatively hard in the vertical direction, resilient in chassis longitudinal and transverse direction primary suspension, which relative movements of the wheelsets 2 and 3 relative to the bogie frame 4 in terms of at least approximately radial adjustment of the wheelset 7 when passing through a track curve and, when extending from the track curve, due to the restoring force of the elastically deformed spring elements 28, a return of the wheelsets 7 each allowed in a mutually parallel normal position. In this case, a favorable stress on the spring elements 28 can be achieved, which experience corresponding deflections predominantly in the longitudinal direction, and only relatively small deflections in the transverse direction.

Die Radsätze 2 und 3 können ferner über mindestens eine aktive oder passive Verstelleinrichtung im Sinne der vorstehend beschriebenen Einstell- und Rückstellbewegungen der Radsatzachsen 7 verstellbar gekoppelt sein. Entsprechend kann die selbsttätige Radialeinstellung der Radsätze 2 und 3 unterstützt und damit eine Verbesserung des Fahrverhaltens des Fahrwerks 1 bei Kurvenfahrt, insbesondere beim Befahren kurvenreicher Strecken mit engen Kurvenradien, erzielt werden.The wheelsets 2 and 3 may also be adjustably coupled via at least one active or passive adjusting device in the sense of adjusting and restoring movements of the wheelset 7 described above. Accordingly, the automatic Radial adjustment of the wheelsets 2 and 3 supported and thus an improvement in the handling of the chassis 1 when cornering, especially when driving on winding roads with tight curve radii, can be achieved.

Bei der dargestellten Ausführung sind zwei entsprechende, unterhalb der Längsträger 26 angeordnete aktive Stellvorrichtungen 43 vorgesehen, welche je ein Kolben/Zylinderaggregat 44 enthalten, dessen Zylinder am betreffenden Längsträger 26 gehalten, z.B. in Querrichtung beweglich angelenkt, und darstellungsgemäss mit einer Stange 45 verbunden ist, welche an der mit dem Radsatz 2 gekoppelten Konsole 30 raumbeweglich angelenkt ist, und dessen Kolben über eine Kolbenstange 46 an der mit dem Radsatz 3 gekoppelten Konsole 30 raumbeweglich angelenkt ist. Die Zylinderräume der beiden Kolben/Zylinderaggregate 44 können über zwei Steuerleitungen 47 und 48 kreuzweise miteinander verbunden und über eine Steuereinrichtung 50 an eine nicht dargestellte Quelle eines pneumatischen oder hydraulischen Druckmittels angeschlossen sein. Ueber die Steuereinrichtung 50, welche in Abhängigkeit von Steuersignalen eines die Winkelstellung einer der Radsatzachsen 7 oder einen entsprechenden Parameter erfassenden Signalgebers 51 betätigbar ist, sind die Zylinderräume der Kolben/Zylinderaggregate 44 je in entgegengesetztem Sinn entweder über die Steuerleitung 47 oder über die Steuerleitung 48 mit Druckmittel beaufschlagbar, so dass die Radsätze 2 und 3 jeweils zwischen der der Geradeausfahrt entsprechenden Normalstellung und zwei einander entgegengesetzten Auslenkstellungen um eine radsatzmittige Hochachse verstellbar und feststellbar geführt sind.In the illustrated embodiment, two corresponding, located below the side members 26 active adjusting devices 43 are provided, each containing a piston / cylinder unit 44, the cylinder of the respective longitudinal beam 26 held, for example, articulated movable in the transverse direction, and is connected according to the representation with a rod 45, which is hinged to the console 30 coupled to the wheelset 2 spatially movable, and the piston is articulated via a piston rod 46 on the coupled to the wheel 3 console 30 spatially movable. The cylinder chambers of the two piston / cylinder units 44 can be cross-connected to each other via two control lines 47 and 48 and connected via a control device 50 to a source, not shown, of a pneumatic or hydraulic pressure medium. Via the control device 50, which is operable in response to control signals of the angular position of the wheelset 7 or a corresponding parameter detecting signal generator 51, the cylinder chambers of the piston / cylinder units 44 are each in the opposite sense either via the control line 47 or via the control line 48 Pressure medium acted upon, so that the wheelsets 2 and 3 respectively between the straight ahead corresponding normal position and two opposite deflection positions are guided adjustable and lockable about a Radsatzmittige vertical axis.

Anstelle eines Kolben-/Zylinderaggregats kann auch eine Luftfeder oder ein beliebig anderes Stellelement, z.B. ein elektromechanischer Aktuator, vorgesehen sein. Die beschriebene Anordnung ermöglicht eine passive, selbsttätige Einstellung mit überlagerter aktiver Steuerung der Radsatzachsen 7, welche, etwa bei einem Ausfall der Steuereinrichtung 50, durch die Rückstellkräfte der Federelemente 28 jeweils in die neutrale Normallage zurückgeführt werden können. Derartige Verstelleinrichtungen sind insbesondere von Vorteil für Fahrzeuge zum Befahren von Gleisanlagen mit engen Kurvenradien.Instead of a piston / cylinder unit, an air spring or any other adjusting element, e.g. an electromechanical actuator, be provided. The arrangement described enables a passive, automatic adjustment with superimposed active control of the wheelset axles 7, which, for example in the case of a failure of the control device 50, can be returned to the neutral normal position by the restoring forces of the spring elements 28. Such adjusting devices are particularly advantageous for vehicles for driving on track systems with tight curve radii.

In den Zeichnungsfiguren sind einander entsprechende Teile mit den gleichen Bezugszeichen versehen. Das in den Fig.4 und 5 dargestellte Fahrwerk 61 ist als rahmenlose Traganordnung für den Fahrzeugkasten 6 ausgebildet. Die je aus dem Antriebsmotor 14 und dem Zahnradgetriebe 15 gebildeten Antriebseinheiten der Radsätze 2 und 3 sind mit einem zwischen den Gehäusen der beiden Antriebsmotoren 14 angeordneten zentralen Tragteil 62 zu einer starren Tragkonstruktion 63 verbunden, welche über zwei innerhalb der Spurweite der Radsätze 2 und 3 angeordnete Führungsvorrichtungen 65 und 65a auf den Radsatzachsen 7 abgestützt ist. Die Führungsvorrichtungen 65 und 65a enthalten je zwei beidseits der Tragkonstruktion 63 angeordnete, auf den Radsatzachsen 7 gelagerte und von diesen gegen die Quermittelebene E des Fahrwerks 61 weisende Längslenker 66 und 67 bzw. 66a und 67a, welche über eine in der Quermittelebene E angeordnete Koppelvorrichtung 68 miteinander in Fahrwerk-Längsrichtung beweglich gekoppelt sind.In the drawing figures corresponding parts are provided with the same reference numerals. The chassis 61 shown in Figures 4 and 5 is designed as a frameless support arrangement for the vehicle body 6. Each formed from the drive motor 14 and the gear transmission 15 drive units of the wheelsets 2 and 3 are connected to a arranged between the housings of the two drive motors 14 central support member 62 to a rigid support structure 63, which arranged over two within the track of the wheelsets 2 and 3 Guide devices 65 and 65a is supported on the wheelset 7. The guide devices 65 and 65a each contain two arranged on both sides of the support structure 63, mounted on the wheelset 7 and facing away from the transverse center plane E of the chassis 61 trailing arm 66 and 67 and 66a and 67a, which via a arranged in the transverse center plane E coupling device 68th are movably coupled together in the chassis longitudinal direction.

Die Koppelvorrichtung 68 enthält eine am Tragteil 62 drehbar gelagerte, querliegend angeordnete Koppelwelle 70 mit beidenends drehfest angebrachten Anschlussteilen 71 und 72, wobei am einen Anschlussteil 71 die auf der einen Seite des Fahrwerks 61 angeordneten Längslenker 66 und 66a oberhalb bzw. unterhalb der Drehachse der Koppelwelle 70 angelenkt sind und am anderen Anschlussteil 72 die auf der anderen Seite des Fahrwerks 61 gegenüberliegend angeordneten Längslenker 67 und 67a gegensinnig, je unterhalb bzw. oberhalb der Drehachse, angelenkt sind. Entsprechend sind die Radsätze 2 und 3 über die Koppelvorrichtung 68 miteinander gegensinnig auslenkbar gekoppelt, wobei die Radsatzachsen 7 je im wesentlichen radial zu einem jeweils zu durchfahrenden Gleisbogen einstellbar sind.The coupling device 68 includes a pivotally mounted on the support member 62, transversely arranged coupling shaft 70 with both ends rotatably mounted connection parts 71st and 72, wherein at a connecting part 71 arranged on one side of the chassis 61 trailing arm 66 and 66a are hinged above or below the axis of rotation of the coupling shaft 70 and the other connection part 72 on the other side of the chassis 61 oppositely arranged trailing arm 67 and 67a in opposite directions, depending below or above the axis of rotation, are hinged. Correspondingly, the wheelsets 2 and 3 are coupled in opposite directions via the coupling device 68 in opposite directions, wherein the wheelset axles 7 are each substantially radially adjustable to a respective track to be traveled through.

Die Tragkonstruktion 63 ist über an den Gehäusen des Antriebsmotors 14 und des Stirnradgetriebes 15 angebrachte Konsolen 64 auf vier Federelementen 28 abgestützt, welche je auf einem der Längslenker 66 und 67 bzw. 66a und 67a angeordnet sind. Die entsprechend voll abgefederten Antriebseinheiten sind mit den Radsätzen 2 und 3 je über eine Kardanhohlwelle 73 gekoppelt, welche im wesentlichen rückwirkungsfreie, jeweils aus der Einfederung der Tragkonstruktion 63 und aus den Auslenkungen des Radsatzes 2 bzw. 3 resultierende Relativbewegungen der Radsatzachse 7 zulässt. Die beschriebene Anordnung ermöglicht ebenfalls eine besonders einfache, kompakte Bauweise des Fahrwerks 61, welche relativ wenige, günstig beanspruchte tragende Teile aufweist und welche, im Vergleich mit bisherigen Ausführungen, eine beträchtliche Gewichtseinsparung gewährleistet.The support structure 63 is supported on the housings of the drive motor 14 and the spur gear 15 mounted brackets 64 on four spring elements 28, which are each arranged on one of the trailing arms 66 and 67 and 66 a and 67 a. The corresponding fully sprung drive units are coupled to the wheelsets 2 and 3 each via a Kardanhohlwelle 73, which permits substantially non-reactive, respectively from the deflection of the support structure 63 and from the deflections of the wheelset 2 and 3 resulting relative movements of the wheelset 7. The arrangement described also allows a particularly simple, compact design of the chassis 61, which has relatively few, low-stress load-bearing parts and which, in comparison with previous versions, ensures a considerable weight saving.

Die Tragkonstruktion 63 ist über eine Wankstützvorrichtung 74 mit dem Fahrzeugkasten 6 gekoppelt, der über die Federanordnung 5 und das Axiallager 35 auf dem zentralen Tragteil 62 abgestützt ist. Die Wankstützvorrichtung 74 enthält einen im Tragteil 62 gelagerten, querliegend angeordneten Torsionsstab 75 mit an diesem beidenends drehfest angebrachten, in eine Fahrwerklängsrichtung weisenden Lenkhebeln 76 sowie zwei beidseits des Tragteils 62 angeordnete Pendelstützen 12, welche an den Lenkhebeln 76 und am Fahrzeugkasten 6 je raumbeweglich schwenkbar angelenkt sind. Durch entsprechende Bemessung des Torsionsstabes 75, der Lenkhebel 76 und der Pendelstützen 12 sowie durch die Wahl der Abstände zwischen diesen Teilen lässt sich die Wanksteifigkeit zwischen dem Fahrwerk 61 und dem Fahrzeugkasten 6 optimieren. Bei dieser Ausführung kann die Vorrichtung 13 oder eine andere Vorrichtung zur Uebertragung der Zug- und Bremskräfte, z.B. eine Zug-/Druckstange, am Gehäuse des Antriebsmotors 14 angelenkt sein.The support structure 63 is coupled via a roll support device 74 with the vehicle body 6, which is supported on the central support member 62 via the spring assembly 5 and the thrust bearing 35. The roll support device 74 includes a in Support member 62 mounted, transversely mounted torsion bar 75 with rotatably mounted at this two ends, pointing in a chassis longitudinal direction steering levers 76 and two on both sides of the support member 62 arranged pendulum supports 12, which are hinged to the steering levers 76 and the vehicle body 6 each spatially pivotable. By appropriate dimensioning of the torsion bar 75, the steering lever 76 and the pendulum supports 12 and by the choice of distances between these parts, the roll stiffness between the chassis 61 and the vehicle body 6 can be optimized. In this embodiment, the device 13 or another device for transmitting the tensile and braking forces, such as a pull / push rod, be hinged to the housing of the drive motor 14.

So können anstelle eines einzigen Federelements auch zwei oder mehrere, z.B. vier, entsprechende Federelemente innerhalb und/oder ausserhalb des zentralen Bereichs der Tragkonstruktion, z.B. im Bereich der Längsträger 26 des Fahrwerks 1, angeordnet sein. Ebenso kann anstelle einer oder mehrerer Luftfedern auch eine Federanordnung mit einem oder mehreren hydraulischen oder hydropneumatischen Federelementen vorgesehen sein. Anstelle des dargestellten Axiallagers, welches sich durch eine besonders kompakte Bauweise auszeichnet, kann auch eine andere Stützanordnung, z.B. ein Drehkranz, vorgesehen sein. Nach einer weiteren, nicht dargestellten Ausführungsform der Erfindung kann auch nur einer der Radsätze des Fahrwerks mit einer Antriebseinrichtung versehen und über entsprechende Führungsvorrichtungen mit einem Laufradsatz gekoppelt sein. Ebenso können Lauffahrwerke mit antriebslosen Laufradsätzen erfindungsgemäss ausgebildet sein.Numerous modified embodiments of the invention are possible. Thus, instead of a single spring element, two or more, for example four, corresponding spring elements can be arranged inside and / or outside the central region of the supporting structure, for example in the region of the longitudinal members 26 of the chassis 1. Likewise, instead of one or more air springs, a spring arrangement may also be provided with one or more hydraulic or hydropneumatic spring elements. Instead of the illustrated thrust bearing, which is characterized by a particularly compact design, can also be another support assembly, such as a turntable be provided. According to a further, not shown embodiment of the invention, only one of the wheelsets of the chassis can be provided with a drive device and coupled via corresponding guide devices with a wheelset. Likewise, running gears can be designed according to the invention with drive-free wheelsets.

Zusammenfassend lässt sich die Erfindung wie folgt beschreiben:In summary, the invention can be described as follows:

Das Fahrwerk enthält zwei Radsätze, welche über zwei je auf einer der Radsatzachsen gelagerte Führungsvorrichtungen und eine Koppelvorrichtung miteinander gegensinnig auslenkbar gekoppelt sind, und eine innerhalb der Spurweite der Radsätze angeordnete Tragkonstruktion, auf der der Fahrzeugkasten über eine zentrale Federanordnung abgestützt ist. Die Tragkonstruktion, z.B. ein Drehgestellrahmen, ist über je zumindest in Fahrwerk-Längsrichtung nachgiebige Federelemente auf je zwischen den Rädern angeordneten, inneren Stützteilen abgestützt, welche an den Führungsvorrichtungen ausgebildet sind. Die Führungsvorrichtungen sind über eine Halteeinrichtung, z.B. Pendelstützen und/oder eine Vorrichtung zum Uebertragen von Zug- und Bremskräften mit dem Fahrzeugkasten in Querrichtung beweglich gekoppelt.
