Abstract

The bogie has a frame (8) with an axle at each end. Each axle is supported in bearings (2) mounted on springs (7) so that each bearing has a limited degree of longitudinal movement w.r.t the frame. Each bearing (2) is connected by a pivoted link (5) to one end of a central link (9) which is pivoted to the frame. The linkages are so arranged that the two bearings on the same side of the frame either move simultaneously towards each other or away from each other.

Description

Die Erfindung bezieht sich auf ein Drehgestell mit gelenkten Radsätzen, bei dem die Radsätze durch Lenker untereinander radial einstellbar geführt sind.The invention relates to a bogie with steered wheel sets, in which the wheel sets are guided radially adjustable by the handlebars.

Durch die DE-AS 16 05 826 ist ein Drehgestell bekannt, bei dem die Radsätze durch zwei an diametral gelegenen Radsatzlagern angreifende Lenker radial einstellbar geführt sind. Die an den Radsatzlagern angeschlossenen Lenker sind in Drehgestellmitte über einen Hebel drehfest mit einer Welle verbunden, die in einem Drehgestellrahmen quer zur Fahrtrichtung liegend drehbar gelagert ist. Die beiden Hebel sind um 180° zueinander versetzt, so daß sich beim Durchfahren eines Gleisbogens nach dem Anlaufen des vorderen Radsatzes und dessen radiale Einstellung auf dem Krümmungsmittelpunkt des Gleisbogens über die Lenker auch der nachfolgende Radsatz radial auf den Krümmungsmittel­punkt hin einstellen kann. Eine solche Lenkeinrichtung hat den entscheidenden Nachteil, daß über den Lenkmechanismus keine Übertragung von Zug- und Stoßkräften vom vorderen auf den hinteren Radsatz möglich ist.From DE-AS 16 05 826 a bogie is known in which the wheel sets are guided in a radially adjustable manner by two links acting on diametrically located wheel set bearings. The handlebars connected to the wheelset bearings are rotatably connected in the center of the bogie via a lever to a shaft which is rotatably mounted in a bogie frame lying transversely to the direction of travel. The two levers are offset by 180 ° to each other, so that when driving through a curve after starting the front wheel set and its radial adjustment on the center of curvature of the curve via the handlebars, the following wheel set can also adjust radially towards the center of curvature. Such a steering device has the decisive disadvantage that no transmission of tensile and impact forces from the front to the rear wheelset is possible via the steering mechanism.

Hier setzt die Erfindung ein, deren Aufgabe darin besteht, einen Lenkmechanismus gemäß dem Gattungsbegriff so weiterzu­bilden, daß eine Übertragung der Zug- und Stoßkräfte von einem Radsatz auf den anderen möglich ist, ohne daß die radiale Einstellbarkeit der Radsätze darunter beeinträchtigt wird.This is where the invention comes in, the object of which is to further develop a steering mechanism according to the generic term such that transmission of the tensile and impact forces from one wheel set to the other is possible without the radial adjustability of the wheel sets below being impaired.

Gelöst wird diese Aufgabe zum einen dadurch, daß jedes der vier Radsatzlager elastisch an Lenker angeschlossen ist, daß dabei ein erster und zweiter Lenker einer Drehgestellseite mit den Enden eines ersten Hebels verbunden ist, daß ein dritter und vierter Lenker der anderen Drehgestellseite mit den Enden eines zweiten Hebels verbunden ist, wobei der erste und zweite Hebel welche in Mittellage senkrecht stehen drehfest an eine Welle angeschlossen sind, welche drehbar in Drehgestellmitte quer zur Fahrtrichtung liegend in Langträgern eines Drehgestell­rahmens drehbar gelagert ist, und daß dabei der erste und vierte Lenker am unteren Ende des ersten, bzw. zweiten Hebels ange­schlossen ist, während die zweiten und dritten Lenker am oberen Ende des ersten bzw. zweiten Hebels angeschlossen sind.This object is achieved on the one hand by the fact that each of the four wheelset bearings is elastically connected to the handlebars, that a first and second link on one side of the bogie is connected to the ends of a first lever, that a third and fourth link on the other side of the bogie is connected to the ends of one second lever is connected, wherein the first and second levers which are perpendicular in the middle position are rotatably connected to a shaft which is rotatably mounted in the middle of the bogie transverse to the direction of travel in long girders of a bogie frame, and that the first and fourth links at the lower end of the first and second lever is connected, while the second and third links are connected to the upper end of the first and second lever.

Dadurch, daß sämtliche Radsatzlager durch Lenker und Welle funktionell untereinander verbunden sind, können die Rad­sätze Drehbewegungen um eine senkrechte Achse ausführen und sich somit radial in Richtung eines Krümmungsmittelpunktes eines Gleisbogens einstellen, dagegen sind lineare Ver­schiebungen in Fahrtrichtung ausgeschlossen, da dies durch die Welle verhindert wird.Due to the fact that all wheel set bearings are functionally connected to each other by the handlebar and shaft, the wheel sets can perform rotary movements around a vertical axis and thus adjust radially in the direction of a center of curvature of a curved track, on the other hand linear displacements in the direction of travel are excluded, since this is prevented by the shaft .

Zum anderen wird diese Aufgabe dadurch gelöst, daß jeder Radsatz eines Drehgestelles eine hohle Radsatzwelle aufweist, in der eine Welle koaxial drehbar gelagert ist, daß die Welle an ihren freien Enden drehfest mit einem ersten bzw. zweiten Hebel verbunden ist, wobei die beiden Hebel um 180° versetzt sind, und daß der erste Hebel mit dem ersten Lenker und der zweite Hebel mit dem zweiten Lenker elastisch verbunden ist und beide Lenker in angrenzenden Langträgern eines Drehgestellrahmens in gleicher Entfernung von der Radsatzwelle gelenkig gelagert sind.On the other hand, this object is achieved in that each wheel set of a bogie has a hollow wheel set shaft, in which a shaft is rotatably mounted coaxially, that the shaft is rotatably connected at its free ends to a first or second lever, the two levers around Are offset 180 °, and that the first lever is elastically connected to the first link and the second lever to the second link and both links are articulated in adjacent long beams of a bogie frame at the same distance from the wheelset shaft.

Eine solche Einrichtung ist besonders vorteilhaft beim Einbau eines Monomotors. Dadurch,daß die Welle durch die hohle Radsatz­welle geführt wird, können ungehindert die Getriebemittel zwischen Monomotor und den Radsatzwellen angeordnet werden.Such a device is particularly advantageous when installing a mono motor. Because the shaft is guided through the hollow wheelset shaft, the transmission means can be arranged between the monomotor and the wheelset shafts without hindrance.

Des weiteren kann die Aufgabe dadurch gelöst werden, daß jedes Rad eines Radsatzes in ersten und zweiten Radsatz­lagern geführt ist und die drehmomentschlüssige Verbindung der beiden Räder eines Radsatzes durch eine Gelenkwelle erfolgt, beispielsweise eine Kardanwelle, wobei jedem Rad ein Gelenk zugeordnet ist, daß das erste Radsatzlager an einem ersten Lenker und einem ersten Hebel und das zweite Radsatzlager an einem zweiten Lenker und einem zweiten Hebel angeschlossen ist, wobei die beiden Hebel drehfest und um 180° zueinander versetzt mit einer ersten Welle verbunden sind, welche quer zur Fahrtrichtung liegend in Langträgern des Drehgestellrahmens drehbar gelagert ist, daß ein zweiter Radsatz funktionell über Verbindungslenker mit dem ersten Radsatz verbunden ist, wobei symmetrisch zur Mittelquer­ebene eine zweite Welle vorgesehen ist, welche über Lenker und Hebel den Radsatz in gleicher Weise wie den Radsatz steuert.Furthermore, the object can be achieved in that each wheel of a wheel set is guided in first and second wheel set bearings and the torque-locking connection of the two wheels of a wheel set is carried out by a cardan shaft, for example a cardan shaft, each wheel being assigned a joint that the first Wheelset bearings are connected to a first link and a first lever and the second wheelset bearing is connected to a second link and a second lever, the two levers being connected in a rotationally fixed manner and offset by 180 ° to one another with a first shaft which lies transversely to the direction of travel in long beams of the Bogie frame is rotatably mounted, that a second wheel set is functionally connected to the first wheel set via connecting links, symmetrical to the central transverse plane, a second shaft is provided which controls the wheel set in the same way as the wheel set via handlebars and levers.

Als besonderer Vorteil dieser Bauart ist zu nennen, daß der Anlaufwinkel in der Kurve auf Null gestellt werden kann. Der Antrieb beider Räder des Radsatzes kann in relativ einfacher Weise vom Motor über die Gelenkwelle erfolgen.A particular advantage of this design is that the run-up angle in the curve can be set to zero. Both wheels of the wheel set can be driven in a relatively simple manner by the motor via the cardan shaft.

In anderer Weise kann die Aufgabe dadurch gelöst werden, daß das Drehgestell über vier Losräder verfügt, wobei jedes Losrad mittels einer Drehachse im Radsatzlager gelagert ist, welches elastisch im Langträger des Drehgestellrahmens geführt ist, daß die über jedes Losrad verlängerten Drehachsen an Lenker angeschlossen sind, daß dabei ein erster und zweiter Lenker einer Drehgestellseite mit den Enden eines ersten Hebels verbunden ist, daß ein dritter und vierter Lenker der anderen Drehgestellseite mit den Enden eines zweiten Hebels verbunden ist, wobei der erste und zweite Hebel welche in Mittellage senkrecht stehen drehfest an eine Welle angeschlossen sind, welche drehbar in Drehgestellmitte quer zur Fahrtrichtung liegend in Langträgern eines Drehge­stellrahmens drehbar gelagert ist, und daß dabei der erste und vierte Lenker am unteren Ende des ersten, bzw. zweiten Hebels angeschlossen ist, während die zweiten und dritten Lenker am oberen Ende des ersten bzw. zweiten Hebels ange­schlossen sind.In another way, the object can be achieved in that the bogie has four idler wheels, each idler wheel being mounted in the axle set bearing by means of a pivot axis which is guided elastically in the long beam of the bogie frame, that the pivot axes extended via each idler wheel are connected to handlebars, that a first and second link on one side of the bogie is connected to the ends of a first lever, that a third and fourth link on the other side of the bogie is connected to the ends of a second lever, the first and second levers, which are perpendicular in the central position, rotatably connected to one Shaft are connected, which is rotatably mounted in the long girders of a bogie frame in the middle of the bogie lying transversely to the direction of travel, and that the first and fourth links are connected to the lower end of the first and second lever, while the second and third links are connected to the upper end of the first and second lever are connected.

Ein Drehgestell mit Losrädern besitzt den Vorteil, daß der Wegausgleich zwischen den innen und den außen laufenden Rädern beim Bogenlauf ohne Zwang möglich ist. Da der Raum zwischen den Losrädern frei ist kann er für einen tief liegenden durchgehenden Fußboden genutzt werden. Die in Höhe der Radsatzlager liegende Welle kann zu diesem Zweck durchaus auch tiefer im Drehgestellrahmen gelagert werden.A bogie with idler wheels has the advantage that the path compensation between the inside and outside running wheels is possible without constraint when the sheet is running. Since the space between the idler gears is free, it can be used for a deep, continuous floor. For this purpose, the shaft lying at the level of the wheelset bearings can also be stored deeper in the bogie frame.

Zur Lenkung von Radsätzen 1 eines Drehgestelles wird wie in Figur 1 dargestellt, jedes Radsatzlager 2 elastisch an Lenker 3 bis 6 angeschlossen. Die Radsatzlenker 2 sind über Primärfedern 7 längs- und querelastisch mit Langträgern 8 eines Drehgestellrahmens verbunden, so daß sich die Radsätze 1 beim Bogenlauf ohne größeren Widerstand in Richtung auf einen Krümmungsmittelpunkt eines Gleisbogens ausrichten können. Zur Koppelung der Radsätze 1 untereinander werden die Radsatzlager 2 einer Drehgestellseite über einen ersten und zweiten Lenker 3 und 4 verbunden, wobei die Lenker 3 und 4 in Drehgestellmitte an einen in Ausgangslage senkrecht stehenden ersten Hebel 9 angelenkt sind. Dieser erste Hebel 9 ist drehfest mit einer Welle 10 verbunden, welche in den Langträgern 8 drehbar ge­lagert ist und die auf der anderen Drehgestellseite drehfest an einen zweiten Hebel 11 (Figur 2) angeschlossen ist, welcher in Ausgangslage ebenfalls senkrecht steht.For steering wheel sets 1 of a bogie, as shown in FIG. 1, each wheel set bearing 2 is connected elastically to handlebars 3 to 6. The wheelset link 2 are longitudinally and transversely elastically connected to the long beams 8 of a bogie frame via primary springs 7, so that the wheelsets 1 can align themselves towards a center of curvature of a railroad track without greater resistance. To couple the wheel sets 1 to one another, the wheel set bearings 2 of a bogie side are connected via a first and second link 3 and 4, the links 3 and 4 being articulated in the center of the bogie to a first lever 9 which is perpendicular in the starting position. This first lever 9 is non-rotatably connected to a shaft 10 which is rotatably mounted in the long beams 8 and which is non-rotatably connected on the other side of the bogie to a second lever 11 (FIG. 2), which is also perpendicular in the starting position.

An diesem zweiten Hebel sind nach Figur 2 ein dritter und vierter Lenker 5 und 6 angelenkt, die mit den Radsatzlagern 2 verbunden sind.According to FIG. 2, a third and fourth link 5 and 6, which are connected to the wheelset bearings 2, are articulated on this second lever.

Aus Figur 3 ist in räumlicher Darstellung die Lage der Lenker 3 bis 6 zu ersehen. Die Lenker 3 und 5 und die Lenker 4 und 6 sind jeweils um 180° versetzt. Die Lenker 3 und 4 sind dabei ebenfalls um 180° versetzt an den Enden des ersten Hebels 9 angelenkt, während die Lenker 5 und 6 an den Enden des zweiten Hebels 11 angelenkt sind. Die Hebel 9 und 11 sind durch die Welle 10 drehfest verbunden, die drehbar in den angedeuteten Lang­trägern 8 des Drehgestellrahmens gelagert ist.From Figure 3, the position of the handlebars 3 to 6 can be seen in a spatial representation. The links 3 and 5 and the links 4 and 6 are each offset by 180 °. The links 3 and 4 are also articulated by 180 ° at the ends of the first lever 9, while the links 5 and 6 are articulated at the ends of the second lever 11. The levers 9 and 11 are through the shaft 10 rotatably connected, which is rotatably mounted in the indicated long beams 8 of the bogie frame.

Beim Durchfahren eines Gleisbogens ist leicht einzusehen, daß, wenn sich das Radsatzlager 2 einer Drehgestellseite in Richtung eines ersten Vektors 12 bewegt, sich das Radsatz­lager 2 der gleichen Seite in Richtung eines zweiten Vektors 13 bewegt und sich die beiden Radsatzlager 2 der anderen Seite zwangsläufig um den gleichen Wegbetrag in Richtung der dritten und vierten Vektoren 14 und 15 bewegen, so daß die Radsätze 1 die strichliert eingezeichnete Lage einnehmen und zum Krümmungsmittelpunkt eines Gleisbogens hin ausge­richtet sind.When driving through a track curve it is easy to see that when the wheelset bearing 2 of one bogie side moves in the direction of a first vector 12, the wheelset bearing 2 on the same side moves in the direction of a second vector 13 and the two wheelset bearings 2 on the other side inevitably move around move the same path in the direction of the third and fourth vectors 14 and 15, so that the wheel sets 1 assume the position shown in broken lines and are oriented toward the center of curvature of a curved track.

Im Falle, daß ein Monomotor für den Einbau in ein Triebdreh­gestell vorgesehen ist, ist es nach Figur 4 vorteilhaft die Welle 10 in eine hohle Radsatzwelle 16 des Radsatzes 1 einzubauen. Die Welle 10 ist konzentrisch in der Radsatz­welle 16 gelagert und weist an ihren Enden einen ersten und zweiten Hebel 9 und 11 auf, die beide drehfest mit Welle 10 verbunden sind. Der erste Hebel 9 ist über einen ersten Lenker 3 und der zweite Hebel 11 über einen zweiten Lenker 4 mit den Langträgern 8 des Drehgestellrahmens gelenkig verbunden.In the event that a monomotor is provided for installation in a motor bogie, it is advantageous according to FIG. 4 to install the shaft 10 in a hollow wheel set shaft 16 of the wheel set 1. The shaft 10 is mounted concentrically in the wheelset shaft 16 and has at its ends a first and second lever 9 and 11, both of which are connected to the shaft 10 in a rotationally fixed manner. The first lever 9 is articulated via a first link 3 and the second lever 11 via a second link 4 with the long beams 8 of the bogie frame.

Wie aus Figur 5 zu ersehen ist, sind die Lenker 3 und 4 der Radsatzführung nach Figur 4 gleich lang, die Hebel 9 und 11 sind um 180° versetzt. Jeder Radsatz 1 des Drehgestelles ist in gleicher Weise angelenkt, wie in den Figuren 4 und 5 dar­gestellt.As can be seen from Figure 5, the links 3 and 4 of the wheelset guide according to Figure 4 are of equal length, the levers 9 and 11 are offset by 180 °. Each wheel set 1 of the bogie is articulated in the same way as shown in Figures 4 and 5.

Eine Variante der Erfindung mit schwenkbaren Radpaaren ist in Figur 6 dargestellt. Jedes Rad 16 des Drehgestelles ist mittels zweier Radsatzlager 2a, 2b geführt, welche das Rad 16 längs-und querelastisch im nicht dargestellten Drehgestellrahmen führen. Ein Radsatzlager 2a ist an den ersten Lenker 3 und ein zweites Radsatzlager 2b ist an den zweiten Lenker 4 angeschlossen. Beide Lenker 3 und 4 sind über die ersten und zweiten Hebel 9 und 11 drehfest mit der ersten Welle 10a verbunden, die im Langträger 8 drehbar gelagert ist. Die beiden Hebel 9 und 11 sind um 180° versetzt. Über die quer zur Fahrtrichtung liegende Welle 10 ist der Radsatz der anderen Drehgestellseite in gleicher Weise angeschlossen. Zur Übertragung des Drehmoments eines Motors sind die Räder des Radsatzes 1 durch eine Gelenkwelle 17 verbunden, welche als Kardanwelle ausgeführt sein kann. Das Rad 16 ist durch diese Einrichtung ebenso wie die übrigen Räder des Drehgestelles in der Lage, um einen ideellen Punkt 18 zu schwenken. Der Schwenkwinkel ergibt sich bei Kurvenfahrt durch das freie Spiel der Kräfte und Momente der durch Welle 8 verbundenen Räder des Radsatzes 1.A variant of the invention with pivotable wheel pairs is shown in Figure 6. Each wheel 16 of the bogie is guided by means of two wheelset bearings 2a, 2b which make the wheel 16 longitudinally and transversely elastic in the bogie frame, not shown to lead. A wheelset bearing 2a is connected to the first link 3 and a second wheelset bearing 2b is connected to the second link 4. Both links 3 and 4 are non-rotatably connected via the first and second levers 9 and 11 to the first shaft 10a, which is rotatably supported in the long beam 8. The two levers 9 and 11 are offset by 180 °. The wheel set on the other side of the bogie is connected in the same way via the shaft 10 lying transversely to the direction of travel. To transmit the torque of an engine, the wheels of the wheel set 1 are connected by a cardan shaft 17, which can be designed as a cardan shaft. The wheel 16, like the other wheels of the bogie, is able to pivot about an ideal point 18 through this device. When cornering, the swivel angle results from the free play of the forces and moments of the wheels of the wheel set 1 connected by shaft 8.

Die Verbindung der beiden Radsätze 1 und 1a des Drehgestelles ist in Figur 7 schematisch dargestellt. Die erste Welle 10a ist über einen Verbindungslenker 19 mit einer zweiten Welle 10b verbunden, die ebenso wie Welle 10a über Lenker und Hebel an den Radsatz 1b angeschlossen ist.The connection of the two wheel sets 1 and 1a of the bogie is shown schematically in Figure 7. The first shaft 10a is connected via a connecting link 19 to a second shaft 10b which, like the shaft 10a, is connected to the wheel set 1b via a link and lever.

Die Verbindung ist dabei so zu gestalten, daß dem ersten Lenker 3 ein Lenker 3a und dem zweiten Lenker 4 ein Lenker 4a des zweiten Radsatzes 1a zugeordnet ist.The connection is to be designed so that the first link 3 is a link 3a and the second link 4 is a link 4a of the second wheel set 1a.

Um einen vollen Wegausgleich der Räder bei Kurvenfahrt herbeizu­führen, wird nach Figur 8 vorgeschlagen, sämtliche Räder als Losräder auszuführen. Das Rad 16 ist dabei freifliegend im Radsatzlager 2 gelagert, welches wiederum elastisch im nicht dargestellten Langträger des Drehgestellrahmens gelagert ist. Eine Drehachse 19 ist über das Rad 16 hinaus verlängert und ebenso wie die übrigen Räder an Lenker 3 bis 6 angeschlossen, die über Hebel und die Welle 10 untereinander verbunden sind. Die Verbindung der Lenker 3 bis 6 erfolgt ebenso wie unter Figur 3 bereits ausführlich dargestellt wurde.In order to bring about a complete path compensation of the wheels when cornering, it is proposed according to FIG. 8 to design all the wheels as idler wheels. The wheel 16 is freely suspended in the wheelset bearing 2, which in turn is elastically mounted in the long beam, not shown, of the bogie frame. An axis of rotation 19 is extended beyond the wheel 16 and, like the other wheels, is connected to the handlebars 3 to 6, which are connected to one another via the lever and the shaft 10. The connection of the handlebars 3 to 6 takes place, as has already been shown in detail in FIG. 3.

Figur 9 zeigt das mit Losrädern 16 ausgeführte Drehgestell in Seitenansicht. Bei der Anordnung der Lenker 3 bis 6 darf auf die Figuren 1 und 3 verwiesen werden.FIG. 9 shows the bogie designed with idler gears 16 in a side view. When arranging the handlebars 3 to 6, reference may be made to FIGS. 1 and 3.
