Abstract

The invention concerns driven running gear, in particular a bogie, for railway vehicles with a gauge-adjusting arrangement. Single-wheel running gear (70) accommodates a wheel unit (90) consisting of a wheel (94), axle journals (92, 96), non-rotatably connected thereto, and pivot bearings. The wheel unit (90) is axially displaceable as a unit in the single-wheel running gear (70). The axle journal (96) engages with a wheel gear (100) which is flanged to the single-wheel running gear (70) and absorbs the axial movement of the axle journal (96). The wheel gear (100) is driven via a longitudinally displaceable propeller shaft (72) by means of a prime mover (30) mounted separately from the single-wheel running gear. This design produces running gear which can be driven at high speeds and has an adjustable gauge.

Description

Die Erfindung betrifft ein angetriebenes Laufwerk gemäß dem Oberbegriff der Patentansprüche 1 und 2, das aus der DE-PS-1067466 und aus der EP 0 596 408 A bekannt ist.The invention relates to a powered drive according to the The preamble of claims 1 and 2, which from DE-PS-1067466 and is known from EP 0 596 408 A.

In Europa existieren Schienennetze mit unterschiedlichen Spurweiten, beispielsweise ist die Spurweite in Spanien anders als in Frankreich, und Rußland hat eine andere Spurweite als das übrige Westeuropa. Dementsprechend besteht beim grenzüberschreitenden Verkehr der Bedarf an Schienenfahrzeugen, bei denen die Spurweite geändert werden kann, und es wurden in der Vergangenheit verschiedene Vorrichtungen zur Änderung der Spurweite vorgeschlagen.There are different rail networks in Europe Gauges, for example, the gauge is different in Spain than in France, and Russia has a different gauge than the rest of Western Europe. Accordingly, there is in the case of cross-border traffic, the need for rail vehicles, where the track gauge can be changed and there have been various devices in the past proposed to change the gauge.

So könnte beispielsweise für jede Spurweite ein eigenes Laufwerk vorgesehen sein, wobei das jeweils erforderliche Laufwerk bei Bedarf auf die Schiene abgesenkt wird. Diese Lösung ist jedoch wegen des Zusatzgewichtes, der Baugröße und aus Kostengründen betriebstechnisch und wirtschaftlich nicht akzeptabel.For example, there could be a separate one for each gauge Drive may be provided, the required Drive is lowered onto the rail if necessary. This The solution, however, is because of the additional weight, the size and operationally and economically for cost reasons unacceptable.

Eine Verschiebung der Räder auf der Radsatzwelle bzw.-achse ist wegen der ungünstigen Kombination der Funktionen zur Radarretierung auf der Weile und zur Axialverschiebung des Rades ebenfalls keine geeignete Lösung. Wegen der unterschiedlichen Beanspruchungsarten wird dieser Vorschlag in der Ausführung aufwendig oder ist hinsichtlich der Festigkeit unbefriedigend. Des weiteren müssen Bremsvorrichtungen beim Verschieben nachgeführt werden, wodurch besonders schwere und aufwendige Bremsvorrichtungen notwendig werden, die sich fahrdynamisch ungünstig auswirken.A shift of the wheels on the wheelset shaft or axle is due to the unfavorable combination of functions Radarretierung on the while and for the axial displacement of the Rades is also not a suitable solution. Because of the different This proposal is described in stress types the execution is complex or is in terms of strength unsatisfactory. Furthermore, braking devices be tracked when moving, which makes it special heavy and complex braking devices become necessary, that have a negative impact on driving dynamics.

Auch eine Verschiebung vollständiger Laufwerkshalbrahmen einschließlich darin gelagerter Einzelradeinheiten ist kaum realisierbar, da die Kräfte aus dem Verschiebevorgang in den Lagern der gegeneinander verschiebaren Rahmenhälften Biegemomente und Kantenpressungen mit Behinderungen der Gleitbewegung erzeugen, weil die Verschiebekräfte über die von den Verschiebelagern entfernten Räder und somit über Hebelarme über das Laufwerk eingeleitet werden. Wegen Problemen bezüglich der Spurhaltung unter dem Einfluß fahrdynamischer Kräfte müssen die Verbindungsstellen relativ stark dimensioniert werden, was zu einem Mehrgewicht der Fahrwerke führt.Also a move of full drive half frames including individual wheel units stored in it is hardly realizable, since the forces from the shifting process in the bearings of the frame halves that can be shifted against each other Bending moments and edge pressures with disabilities of the Generate sliding movement because the displacement forces over the wheels removed from the sliding bearings and thus over Lever arms are introduced via the drive. Because of problems with regard to tracking under the influence of driving dynamics Forces must be relative to the joints be dimensioned strongly, which leads to an additional weight of the Running gear leads.

In der Eingangs genannten DE-PS-1067466 wird vorgeschlagen, Radeinheiten aus Rad, Achsstummeln und Achslagern an Kurbelschwingen zu lagern, die als ganzes verschiebbar sind. Der Verschiebeweg beim Spurweitenwechsel wird in den Lagern der Kurbelschwingen am Drehgestellrahmen aufgenommen. Auch hier entstehen aufgrund der Kräfte aus dem Verschiebevorgang Biegemomente und Kantenpressungen mit Behinderungen der Gleitbewegung. Auch hier entsteht das Problem, daß konkurrierende Anforderungen an die Lagerstellen der Kurbelschwingen erfüllt werden müssen; diese dienen nämlich einerseits als Führungselemente der Kurbelschwingen unter dem Einfluß fahrdynamischer Kräfte und müssen andererseits die Gleitbewegung beim Spurwechsel gestatten. Auch diese Lösung hat sich im praktischen Bahnbetrieb nicht durchsetzen können. In the aforementioned DE-PS-1067466 it is proposed Wheel units made up of wheels, stub axles and axle bearings on crank arms to store that are movable as a whole. The displacement path when changing the gauge is in the bearings the crank arms on the bogie frame. Also here arise due to the forces from the displacement process Bending moments and edge pressures with disabilities the sliding movement. Again, the problem arises that competing Requirements for the crank arm bearings must be fulfilled; on the one hand, these serve as guide elements of the crank arms under the Influence of dynamic driving forces and on the other hand, the Allow sliding movement when changing lanes. This solution too has not been able to establish itself in practical rail operations.

Dem gegenüber verbleibt als Möglichkeit der Austausch ganzer Laufwerke an den Grenzstellen von Gleisnetzen verschiedener Spurweiten. Der damit verbundene hohe Sach- und Personalaufwand ist jedoch ebenfalls unbefriedigend.In contrast, there remains the possibility of exchanging whole ones Drives at the border points of different track networks Track gauges. The associated high material and personnel expenses is also unsatisfactory.

Als einziges Spurwechselprinzip, das sich in der Praxis bewährt hat, steht das sogenannte "Talgo-Prinzip" zur Verfügung. Bei diesem Spurwechselprinzip werden ganze Radeinheiten, die aus Radachsstummeln, Rad und Lagerung bestehen, innerhalb von Einzelradfahrwerksrahmen verschoben. Die unterschiedlichen Anforderungen, nämlich die Drehlagerung des Rades einerseits und die Gleitlagerung andererseits werden bei diesem "Talgo-Prinzip" konsequent getrennt, indem die Radeinheiten beibehalten werden und als ganzes verschoben werden. Zwar wird das oben genannte "Talgo-Prinzip" heutzutage erfolgreich bei Waggons und dergleichen eingesetzt; wegen der konstruktiven Besonderheiten mit verschiebbaren Achsstummeln, der Lagerung in Einzellaufwerken und dem daraus resultierenden geringen Bauraum zwischen den Einzelrädern, ist es bislang noch nicht gelungen, die Spurweitenverstellung mit einem leistungsstarken Antrieb zu kombinieren. Die Wagen müssen deshalb durch gesonderte Traktionsmittel (Lokomotiven oder Triebköpfe) durch die Spurwechselanlage geschoben werden, was zusätzliche Rangiervorgänge erfordert und Wartezeiten zum An- bzw. Abkuppeln mit sich bringt.As the only lane change principle that has proven itself in practice the so-called "Talgo principle" is available. With this lane change principle, entire wheel units, consisting of stub axles, wheels and bearings, shifted within single wheel chassis. The different Requirements, namely the pivoting of the Rades on the one hand and the plain bearing on the other consistently separated in this "Talgo principle" by the Wheel units are retained and moved as a whole become. Admittedly, the "Talgo principle" mentioned above is used nowadays successfully used on wagons and the like; because of the special design features with sliding Axle stub, storage in individual drives and the resulting resulting small space between the individual wheels, So far it has not been possible to adjust the track width to combine with a powerful drive. The wagons must therefore use separate traction devices (Locomotives or power cars) through the lane change system be pushed, causing additional maneuvers requires and waiting times for coupling and uncoupling brings.

Zwar ist in der oben genannten DE-PS-1067466 erwähnt, daß die Spurwechselvorrichtung mit einem Antrieb versehen ist, konkrete Vorschläge, wie der Antrieb auszugestalten ist, sind jedoch nicht angegeben.It is mentioned in the above-mentioned DE-PS-1067466 that the lane changing device is provided with a drive, concrete suggestions on how to design the drive, are however not specified.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, ein angetriebenes Laufwerk, insbesondere Drehgestell, mit Spurwechseleinrichtung für ein Schienenfahrzeug zu schaffen, das vorzugsweise voll hochgeschwindigkeitstauglich ist und einen automatischen Spurwechsel eines ganzen Zugverbandes ohne Rangieraufenthalte erlaubt. Accordingly, the invention is based on the object a powered drive, in particular bogie, with To create a lane change device for a rail vehicle, which is preferably fully suitable for high speeds and an automatic lane change of an entire train set allowed without shunting visits.

Diese Aufgabe wird durch ein angetriebenes Laufwerk gemäß den Patentansprüchen 1 und 2 gelöst; die abhängigen Ansprüche geben weitere Entwicklungen der Erfindung an.This task is accomplished by a powered drive solved the claims 1 and 2; the dependent claims give further developments of the invention.

Erfindungsgemäß werden zum Spurwechsel jeweils ganze Radeinheiten axial verschoben, wobei die Räder entweder direkt über geeignete Antriebsmaschinen wie Elektro- oder Hydronabenmotoren getrieben werden, die den Verschiebeweg der Achsstummel aufnehmen, oder über ein Radgetriebe, das entsprechend den Verschiebeweg aufnimmt.According to the invention, entire wheel units are used for changing lanes axially shifted, the wheels either directly via suitable drive machines such as electric or hydraulic hub motors be driven, the the displacement of the Record stub axles, or via a gearbox, the corresponding takes up the displacement path.

Die die Radlaufwerke aufnehmenden Einzelradlaufwerke können separat ausgebildet sein oder jeweils paarweise über eine Achsbrücke miteinander verbunden sein.The single wheel drives accommodating the wheel drives can be formed separately or in pairs in each case Axle bridge must be connected to each other.

Insbesondere ist die Antriebsmaschine räumlich von dem Radgetriebe bzw. der Radeinheit getrennt, und die Drehmomentübertragung erfolgt durch Gelenkwellen. Diese Gelenkwellen sind vorzugsweise längsverschieblich ausgebildet und am Radgetriebe bzw. der Antriebsmaschine angelenkt, so daß die Antriebsmaschine am gefederten Wagenkasten befestigt werden kann und somit die ungefederte Masse am Rad sehr klein ist. Die unterschiedlichen Bewegungen des gefederten Wagenkastens bzw. des ungefederten Rades werden aufgrund der Längsverschieblichkeit der Gelenkwellen kompensiert.In particular, the drive machine is spatially separated from the wheel gear or the wheel unit separately, and the torque transmission is done by cardan shafts. These cardan shafts are preferably designed to be longitudinally displaceable and on Wheel gear or the drive machine articulated so that the Drive machine to be attached to the sprung body can and thus the unsprung mass on the wheel is very small. The different movements of the sprung body or the unsprung wheel are due to the Longitudinal displacement of the cardan shafts is compensated.

Dabei ist es möglich, jedem angetriebenen Rad eine eigene Antriebsmaschine und ein eigenes Radgetriebe zuzuordnen, oder jeweils ein Räderpaar gemeinsam über eine Antriebsmaschine und ein gemeinsames Getriebe zu betreiben. Es ist auch möglich eine einzelne Antriebsmaschine über ein zwischengeschaltetes Verteilergetriebe für mehrere Einzelräder zu verwenden.It is possible to have each driven wheel its own To assign the drive machine and its own wheel gear, or a pair of wheels together via a drive machine and operate a common gear. It is it is also possible to have a single drive machine via an intermediate one Transfer case for several single wheels to use.

Erfindungsgemäß ist es weiter vorteilhaft, die Bremsvorrichtung nicht an den Rädern selbst vorzusehen, sondern mit der Antriebswelle zu koppeln, so daß die Bremsung über die Antriebswelle erfolgen kann.According to the invention, it is further advantageous to use the braking device not to be provided on the wheels themselves, but with to couple the drive shaft so that the braking on the Drive shaft can be done.

Erfindungsgemäß sind die Funktionen einzelner Elemente eines Antriebsdrehgestells und eines Spurwechsellaufwerkes konsequent getrennt, so daß keine für das jeweilige Maschinenelement unzulässige Beanspruchungen entstehen. Die Ausbildungen des Laufwerkes hinsichtlich der Funktionen Tragen, Führen, Spurwechseln und Traktions- und Bremskraftübertragung erlaubt ein hochgeschwindigkeitstaugliches Spurwechsellaufwerk hoher fahrdynamischer Qualität. Durch seine besonderen Merkmale ist dieses Laufwerk auch für bogenschnelles Fahren für Züge in Neigetechnik geeignet, und das Laufwerk ist dahingehend ausgebildet, daß neben der Spurwechselfähigkeit auch die Möglichkeit der Radialeinstellung der Räder bei Bedarf gegeben ist.According to the invention, the functions of individual elements are one Drive bogie and a lane change drive consistently separated so that none for each machine element impermissible stresses arise. The trainings the drive with regard to the functions Guiding, changing lanes and transmission of traction and braking power allows a high-speed suitability Lane changing drive of high dynamic quality. By This drive is also special for bow-fast Driving suitable for trains using tilting technology, and the drive is designed so that in addition to the Lane changing ability also the possibility of radial adjustment the wheels are given if necessary.

    • Gemäß Fig. 1 ist ein Wagenkasten 10 über eine Federung/Dämpfung 40 auf einem Drehgestellrahmen 50 abgestützt. Unterhalb des Drehgestellsrahmens sind Einzelradlaufwerke 70 an einer Anlenkung 56 angelenkt und desweiteren mit dem Drehgestellrahmen 50 über eine Feder 52 und eine Dämpfung 54 verbunden.1 is a car body 10 via a suspension / damping 40 supported on a bogie frame 50. Underneath the bogie frame are single wheel drives 70 hinged to a linkage 56 and further with the bogie frame 50 via a spring 52 and a damping 54 connected.

    Wie am besten aus Figur 2 ersichtlich ist, sind die Einzelradlaufwerke gabelförmig ausgebildet und nehmen zwischen den Gabelschenkeln Radeinheiten 90 auf. Jede Radeinheit 90 besteht aus einem Laufrad 94 und Achsstummeln 92 und 96. Nicht dargestellt sind die Drehlager für die Achsstummel. Diese Drehlager sind unverschieblich mit den Achsstummeln 92, 96 verbunden, sie sind jedoch bezüglich dem Einzelradlaufwerk 70 axial verschieblich. Somit kann die gesamte Radeinheit aus Rad, Achsstummeln und Radlagern innerhalb des Einzelradlaufwerks 70 axial verschoben werden, und die unterschiedlichen Positionen des Rades sind in der Zeichnung dargestellt.As best seen in Figure 2, the single wheel drives forked and take between the fork legs wheel units 90. Each wheel unit 90 consists of an impeller 94 and stub axles 92 and 96. The pivot bearings for the stub axles are not shown. These pivot bearings are immovable with the stub axles 92, 96 connected, but they are related to the single wheel drive 70 axially displaceable. So the whole Wheel unit consisting of wheel, stub axles and wheel bearings within of the single wheel drive 70 are axially displaced, and the different positions of the wheel are in the drawing shown.

    Am Einzelradlaufwerk ist ein Radgetriebe 100 angeflanscht, in das der Achsstummel 96 hineinragt, und zwar derart, daß er in dem Radgetriebe axial verschieblich ist. Das Radgetriebe ist über eine Gelenkwelle 72 mit einem am Wagenkasten 10 befestigten Motor 30 verbunden, so daß das Antriebsdrehmoment des Motors 30 über die Gelenkwelle 72 an das Radgetriebe 100 übertragen wird und von dort aus auf den Achsstummel 96.A wheel gear 100 is flanged to the single wheel drive, into which the stub shaft 96 protrudes, in such a way that it is axially displaceable in the wheel gear. The wheel gear is via a cardan shaft 72 with one on the car body 10 attached motor 30 connected so that the drive torque of the motor 30 via the cardan shaft 72 the wheel transmission 100 is transmitted and from there on the stub axle 96.

    Die Gelenkwellen 72 sind mit geringem (idealerweise ohne) Verschiebungswiderstand längsverschieblich, so daß sie sich unterschiedlichen Relativpositionen zwischen Antriebsmaschine 30 und Radgetriebe 100 anpassen können, die wegen der gefederten Lagerung des Wagenkastens 10 während der Fahrt auftreten.The cardan shafts 72 are of low (ideally without) Displacement resistance longitudinally displaceable, so that it is different relative positions between the engine 30 and gear 100 can adjust that because the sprung mounting of the car body 10 during the Ride occur.

    Alle Antriebe der Einzelradlaufwerke sind in diesem Ausführungsbeispiel identisch in Hohlwellenbauart ausgeführt, wobei der Verschiebeweg der Radeinheit beim Spurwechsel durch eine geeignete Kupplung z.B. eine Bogenzahnkupplung aufgenommen werden kann. Die Einzelradlaufwerke können jeweils einzeln unabhängig voneinander oder paarweise radial einstellbar sein, wobei die Radialeinstellung mittels elastischer Anlenkung der Laufwerke am Drehgestellrahmen 50 oder mittels gegenseitiger Kopplung untereinander (Kreuzankerprinzip) oder mittels kastenseitiger Steuerung erfolgen kann.All drives of the single wheel drives are in this embodiment identical in hollow shaft design, whereby the displacement of the wheel unit when changing lanes a suitable coupling e.g. an arch tooth coupling added can be. The single wheel drives can each individually adjustable independently of one another or in pairs radially be, the radial adjustment by means of elastic Articulation of the drives on the bogie frame 50 or by means of mutual coupling (cross anchor principle) or by means of control on the box side can.

    In den Figuren 1 und 2 ist ferner eine Bremsvorrichtung 60 dargestellt, die durch geeignete Befestigungsvorrichtungen am Wagenkasten 10 oder an der Aufhängung 20 für die Antriebsmaschine 30 befestigt sein kann. Die Bremsvorrichtung 60 umfaßt beispielsweise eine Bremsscheibe 64, die über eine Welle 66 mit der Antriebswelle des Motors 30 gekoppelt ist. Auf diese Weise arbeitet die Bremsscheibe nicht direkt an den Radeinheiten, sondern von diesen getrennt. Somit wird das Laufwerk von den fahrdynamisch nachteiligen Massen der Bremsvorrichtung befreit. Weiterhin kann die Reibgeschwindigkeit der Bremsvorrichtung unabhängig von der Drehzahl der Räder den bremstechnisch erforderlichen Werten optimal angepaßt werden.A braking device 60 is also shown in FIGS. 1 and 2 shown by suitable fasteners on the car body 10 or on the suspension 20 for the drive machine 30 can be attached. The braking device 60 includes, for example, a brake disc 64 which over a shaft 66 coupled to the drive shaft of motor 30 is. In this way, the brake disc does not work directly on the wheel units, but separated from them. Consequently the drive from the driving dynamically disadvantageous masses released the braking device. Furthermore, the speed of friction the braking device regardless of the speed the wheels optimally meet the braking requirements be adjusted.

    Die räumliche Trennung der Reibelemente (Bremsscheibe 64, Bremsbacken 62) erlaubt die Ausbildung der Räder des angetrieben Spurwechsellaufwerkes mit einer Gummifederung, welche die ungefederten Massen erfolgreich reduziert und eine leichte Auslegung der Antriebs- und Lauftechnik gestattet. Demgegenüber können auch konventionelle Radbremsscheiben verwendet werden.The spatial separation of the friction elements (brake disc 64, Brake shoes 62) allows the formation of the wheels of the driven Lane changing mechanism with a rubber suspension, which the unsprung masses successfully reduced and one easy design of the drive and running technology allowed. In contrast, conventional wheel brake discs can be used.

    Das in den Figuren 3 und 4 dargestellte zweite Ausführungsbeispiel der Erfindung unterscheidet sich von dem ersten Ausführungsbeispiel im wesentlichen dadurch, daß jeweils eine Antriebsmaschine 32 für den Antrieb eines Räderpaares vorgesehen ist. Wie am Besten aus Figur 4 zu ersehen ist, erfolgt der Antrieb der Radeinheiten durch Hohlwellen-Radsatzgetriebe 110 paarweise, wobei geeignete Kupplungen 116 die Verschiebewege und die Drehmomentübertragung aufnehmen und die Radsatzgetriebe über Federelemente 114 schwebend auf den Achsstummeln der Radeinheiten gelagert sind. Diese Federelemente können vorteilhaft als erschütterungsdämpfende Elastomerlager ausgebildet sein und in einem als Hohlwelle ausgebildeten Achsstummel oder in dem als Hohlwelle 112 ausgebildeten Ende der Radsatzgetriebeabtriebswelle angeordnet sein.The second embodiment shown in Figures 3 and 4 the invention differs from the first Embodiment essentially in that each a drive machine 32 for driving a pair of wheels is provided. As can best be seen from Figure 4, the wheel units are driven by hollow shaft gearboxes 110 in pairs, with suitable couplings 116 record the displacement and torque transmission and the wheelset gears floating over spring elements 114 are stored on the stub axles of the wheel units. This Spring elements can be advantageous as vibration damping Elastomer bearings can be formed and in a Hollow shaft trained stub shaft or in the as a hollow shaft 112 trained end of the wheelset transmission output shaft be arranged.

    Das Radsatzgetriebe ist über eine Gelenkwelle mit der Antriebsmaschine 32 verbunden.The wheelset gearbox is connected to the drive machine via a cardan shaft 32 connected.

    Figur 5 zeigt in der Aufsicht, teilweise weggebrochen, eine alternative Ausführungsform des Radsatzgetriebes. Dieses Hohlwellen-Radsatzgetriebe 120 ist am primär abgefederten Drehgestellrahmen 50 gelagert. Die Verbindungen zwischen den Achsstummeln und dem Radsatzgetriebe 120 erfolgt über Hülsen 124, die Bogenverzahnungen aufweisen, die mit Bogenverzahnungen im inneren der Achsgetriebehohlwelle und mit Bogenverzahnungen außen auf dem Radachsstummel in Eingriff stehen. Die Hülsen 124 werden mittels Federkraft in Richtung quer zur Fahrtrichtung gegen Anlagekalotten 127 gedrückt und dabei zentriert. Der Antrieb erfolgt über die Antriebsmaschine 32 und eine Gelenkwelle 76, die vorteilhafterweise längsverschieblich ist, da das Radsatzgetriebe 120 am primärgefederten Drehrahmengestell 50, die Antriebsmaschine jedoch am primär- und sekundärgefederten Wagenkasten 10 gelagert ist. Figure 5 shows a top view, partially broken away alternative embodiment of the wheelset transmission. This Hollow shaft gearbox 120 is primarily sprung Bogie frame 50 stored. The connections between the stub axles and the gear set 120 takes place via Sleeves 124, which have splines, with splines inside the axle gear hollow shaft and with Arch gears engage on the outside of the stub axle stand. The sleeves 124 are in the direction of spring force pressed transversely to the direction of travel against system domes 127 and centered. The drive takes place via the Drive machine 32 and a propeller shaft 76, which advantageously is longitudinally displaceable since the wheelset gear 120 on the primary suspension swivel frame 50, the drive machine however, on the primary and secondary sprung body 10 is stored.

    In Figur 6 ist das Radgetriebe als Hohlwellen-Achsgetriebe 130 mit Gelenkwellen 134, 136 ausgebildet, das außerhalb der Längsmitte des Fahrzeugs angeordnet ist und am Drehgestellrahmen befestigt ist. Das Hohlwellen-Achsgetriebe 130 weist eine Hohlwelle 132 mit einem der Längsmitte des Fahrzeug zugewandten Flansch 138 auf. An diesem Flansch sind beidseitig etwa gleichlange längsverschiebliche Gelenkwellen 134, 136 angeordnet, wobei der Verschiebeweg der Radeinheiten bzw. deren Achsstummeln in den Gelenkwellen des Radgetriebes aufgenommen wird. Daneben kompensieren die Gelenkwellen die unterschiedlichen Relativbewegungen des Einzelradlagers und des primärgefederten Achsgetriebes 130.In Figure 6, the wheel gear is a hollow shaft axle gear 130 formed with propeller shafts 134, 136, which is outside the longitudinal center of the vehicle is arranged and is attached to the bogie frame. The Hollow shaft axle drive 130 has a hollow shaft 132 a flange 138 facing the longitudinal center of the vehicle on. This flange is approximately the same length on both sides longitudinally displaceable drive shafts 134, 136 arranged, wherein the displacement of the wheel units or their stub axles is recorded in the propeller shafts of the wheel transmission. In addition to compensate the cardan shafts the different relative movements of the independent wheel bearing and the primary-sprung axle drive 130.

    Bei der in den Figuren 7 und 8 dargestellten Ausführungsform ist das Radgetriebe wie bei der ersten Auführungsform direkt am Einzellaufwerk 70 angeflanscht. Allerdings werden bei dieser Ausführungsform alle Radeinheiten über eine einzelne Antriebsmaschine 34 angetrieben, die über eine Gelenkwelle 38, ein Verteilergetriebe 36 und Gelenkwellen 72 mit den Radgetrieben verbunden ist. Das zentrale Verteilergetriebe 36 ist im primär und sekundär abgefederten Kasten des Hauptrahmens gelagert und kann gegebenenfalls als Differentialgetriebe mit geeigneten kontinuierlich oder gestuft arbeitenden Differentialsperren ausgebildet sein.In the embodiment shown in Figures 7 and 8 is the wheel gear as in the first embodiment flanged directly to the single drive 70. However in this embodiment, all wheel units over a single one Drive machine 34 driven by a propeller shaft 38, a transfer case 36 and drive shafts 72 is connected to the wheel gears. The central transfer case 36 is in the primary and secondary suspension box the main frame and can optionally be used as a differential gear with suitable continuous or graded working differential locks.

    Das Verteilergetriebe kann dabei vorteilhaft dahingehend ausgebildet werden, daß die Radgetriebe über jeweils gegenläufig rotierende Gelenkwellen 72 geringen Längsverschiebewiderstandes angetrieben werden, so daß eine Ausrüstung des Triebfahrzeuges mit aktiver oder passiver Neigetechnik, unbeeinflußt von Antriebsmomenten zwischen Rädern und Kasten möglich ist. Dabei können die Radeinheiten einer Seite oder einer geometrischen Achse wahlweise mechanisch untereinander, und bei mehreren Antriebsmaschinen jeweils mit bestimmten Antriebsmaschinen, gekoppelt werden. The transfer case can be advantageous in this regard be trained that the wheel gears each in opposite directions rotating cardan shafts 72 with low longitudinal displacement resistance be driven so that equipment of the Traction vehicle with active or passive tilting technology, unaffected of drive torque between wheels and box is possible. The wheel units on one side or a geometric axis optionally mechanically with each other, and with several prime movers, each with certain Drive machines to be coupled.

    Positionsunterschiede zwischen dem primär und sekundär gefederten Verteilergetriebe 36 und den jeweiligen Radgetrieben, die direkt an den Einzellaufwerken befestigt sind, werden durch die längsverschieblichen Gelenkwellen 72 ausgeglichen.Differences in position between the primary and secondary suspension Transfer case 36 and the respective wheel gears, which are attached directly to the individual drives, are compensated by the longitudinally displaceable cardan shafts 72.

    Wie aus den Figuren 7 und 8 zu ersehen ist, ist mit dem Verteilergetriebe eine Bremsvorrichtung 60 über eine Gelenkwelle 66 verbunden. Die Bremswirkung erfolgt somit vom Rad getrennt in der Bremsvorrichtung über die Welle 66, das Verteilergetriebe 36, die Gelenkwelle 72, das Radgetriebe 100 auf die Radeinheit.As can be seen from Figures 7 and 8, with the Transfer case a braking device 60 via a propeller shaft 66 connected. The braking effect is therefore from Wheel separated in the braking device via shaft 66, the Transfer case 36, the propeller shaft 72, the wheel gear 100 on the wheel unit.

Wie bei der Ausführungsform gemäß Fig. 5 sind auch die Getriebe 120 am Drehgestellrahmen gelagert. Dadurch werden die ungefederten Massen auf ein Minimum reduziert. Die Drehmomentübertragung vom Getriebe zu den Einzelrädern erfolgt über eine Kombination von an sich im Schienenfahrzeugbau bekannten Kupplungen, z.B. in Kardanhohlwellenbauart, und Schiebstücken, die in der Lage sind, die im Betrieb auftretenden radialen und axialen Versätze und Winkelfehler aufzunehmen. Der Verschiebeweg der Radeinheiten beim Spurwechsel wird durch geeignete Schiebestücke formschlüssig, z.B. durch Bogenzahnkupplung oder ähnliches, oder schaltbar reibschlüssig aufgenommen, z.B. durch schaltbare Klemmverbindungen.Fig. 9 shows a variant of Fig. 5, in which the single wheel drives 70 connected by an additional axle bridge 70 ' are.
