Description

Die Erfindung betrifft ein Wiegendrehgestell für ein Schienenfahrzeug und ein Schienenfahrzeug.The invention relates to a cradle bogie for a rail vehicle and a rail vehicle.

Wiegendrehgestelle für Schienenfahrzeuge umfassen gemeinhin Paare loser Räder oder Radsätze mit parallelen Radachsen in einer Achsebene. Die Räder oder Radsätze sind über eine senkrecht zur Achsebene elastische Primärfederung mit einem Rahmen verbunden, der seinerseits über eine senkrecht zur Achsebene elastische Sekundärfederung mit einer Wiege verbunden ist. Die Wiege wiederum kann so mit einem Wagenkasten des Schienenfahrzeugs verbunden werden, dass sich das Wiegendrehgestell um eine Drehachse relativ zum Wagenkasten drehen kann. Dabei ist die Drehachse senkrecht zu den Radachsen.Cradle bogies for rail vehicles commonly comprise loose wheel pairs or wheelsets with parallel wheel axles in one axle plane. The wheels or sets of wheels are connected to a frame via a primary suspension which is elastic perpendicular to the axis plane and which in turn is connected to a cradle via a secondary suspension which is elastic perpendicular to the axis plane. The cradle, in turn, can be connected to a car body of the rail vehicle in such a way that the cradle bogie can rotate about an axis of rotation relative to the car body. The axis of rotation is perpendicular to the wheel axles.

Der Wagenkasten umfasst eine Gelenkkonsole zum gelenkigen Verbinden mit einer weiteren Gelenkkonsole eines vorausfahrenden Schienenfahrzeugs. Das Wiegendrehgestell ist so mit dem Wagenkasten an einem Verbindungspunkt verbunden, dass die Drehachse senkrecht zu einer Fahrzeuglängsachse ist.The car body includes an articulated bracket for articulated connection to another articulated bracket of a preceding rail vehicle. The cradle bogie is connected to the car body at a connection point such that the axis of rotation is perpendicular to a vehicle longitudinal axis.

Dabei verläuft die Fahrzeuglängsachse durch einen Ankoppelpunkt der Gelenkkonsole und schneidet die Drehachse in einem Schnittpunkt. Der Verbindungspunkt ist bezüglich des Wagenkastens entlang einer Fahrzeugquerachse, die senkrecht zu Drehachse und Fahrzeuglängsachse ist, mittig angeordnet.The longitudinal axis of the vehicle runs through a coupling point of the articulated console and intersects the axis of rotation at an intersection. The connection point is arranged centrally with respect to the car body along a transverse axis of the vehicle, which is perpendicular to the axis of rotation and the longitudinal axis of the vehicle.

Speziell geringe Konizität von Losrädern bewirkt, dass Auslenkungen aus der Mittellage auch bei völlig freier Führung nur allmählich in die Gleismitte zurückgeführt werden. Auf Grund parasitärer, reibungsbedingter und/oder einer Exzentrizität des Schwerpunkts geschuldeter Effekte wird im realen Gleis eine Rückführung tatsächlich nie oder nur selten realisiert.The special low conicity of idler wheels means that deflections from the central position are only gradually returned to the center of the track, even if the track is completely free. Due to parasitic, frictional and/or effects due to eccentricity of the center of gravity, in real life track actually never or only rarely realized a return.

Zur Verbesserung der radialen Einstellung der Räder bzw. Radsätze können diese oder das Wiegendrehgestell mit dem eigenen oder einem benachbarten Wagenkasten mechanisch gekoppelt sein.To improve the radial adjustment of the wheels or wheel sets, these or the cradle bogie can be mechanically coupled to the vehicle body itself or to an adjacent one.

Beispielsweise beschreibt DE 195 09 429 C1 einem Wagenkasten eines Schienenfahrzeugs, der über Sekundärfedern auf einem Drehgestellrahmen abgestützt ist, wobei auf jeder Längsseite ein Steuerhebel mittels einer Anlenkung so befestigt ist, dass er Relativbewegungen zwischen Wagenkasten und Drehgestellrahmen in der Sekundärfederung nicht behindert, jedoch im Bereich seiner Anlenkung gegenüber dem Wagenkasten keine Verschiebefreiheit hat.For example describes DE 195 09 429 C1 a wagon body of a rail vehicle, which is supported on a bogie frame via secondary springs, with a control lever being attached on each longitudinal side by means of a linkage in such a way that it does not impede relative movements between the wagon body and bogie frame in the secondary suspension, but in the area of its linkage relative to the wagon body there is no freedom of movement has.

Die starre mechanische Kopplung bewirkt, dass die Räder bzw. Radsätze entsprechend einem idealen Gleisverlaufs und -bogens angelenkt werden. Bei Abweichungen des Verlaufs und/oder Bogens des Gleises von der Idealform für dies dazu, dass die Losräder bzw. Radsätze nicht parallel zum Gleis angelenkt werden, was mit höherem Verschleiß einhergeht.The rigid mechanical coupling causes the wheels or wheel sets to be articulated in accordance with an ideal track course and curve. If the course and/or curve of the track deviates from the ideal shape, this means that the loose wheels or wheelsets are not articulated parallel to the track, which is associated with higher wear.

Die Aufgabe besteht darin, ein gattungsgemäßes Wiegendrehgestell anzugeben, welches mit weniger Verschleiß einhergeht.The object is to specify a generic cradle bogie that is associated with less wear.

DE 16 05 129 A1 , DE 25 44 956 A1 und DE 27 10 983 A1 offenbaren jeweils Wiegendrehgestelle für Schienenfahrzeuge, umfassend eine um eine Drehachse drehbar an einen ersten Wagenkasten ankoppelbare Wiege und einen über ein elastisches Element mit der Wiege verbundenen Rahmen. CH 543 416 A und EP 0 613 809 A1 lehren zusätzliche Gleitlager zur Abstützung des Wagenkasten auf der Wiege. DE 16 05 129 A1 , DE 25 44 956 A1 and DE 27 10 983 A1 each disclose weighing bogies for rail vehicles, comprising a cradle that can be coupled to a first car body so that it can rotate about an axis of rotation, and a frame that is connected to the cradle via an elastic element. CH 543 416 A and EP 0 613 809 A1 teach additional plain bearings to support the car body on the cradle.

Erfindungsgemäß werden daher ein Wiegendrehgestell gemäß Anspruch 1 für ein Schienenfahrzeug und ein Schienenfahrzeug gemäß Anspruch 6 zur Verfügung gestellt.According to the invention, a weighing bogie according to claim 1 for a rail vehicle and a rail vehicle according to claim 6 are therefore made available.

Das Wiegendrehgestell umfasst eine um eine Drehachse drehbar an einen ersten Wagenkasten ankoppelbare Wiege und einen über ein selbstzentrierendes elastisches Element mit der Wiege verbundenen Rahmen. Das elastische Element ist elastisch bezüglich Drehung und/oder Kippen des Rahmens relativ zur Wiege.The cradle bogie comprises a cradle that can be coupled to a first car body so that it can rotate about an axis of rotation, and a frame that is connected to the cradle via a self-centering elastic element. The elastic element is elastic with respect to rotation and/or tilting of the frame relative to the cradle.

Das Wiegendrehgestell ist dadurch gekennzeichnet, dass die Wiege mindestens ein Ankoppelelement zum weiteren Ankoppeln einer mechanischen Anlenkvorrichtung an einen zweiten Wagenkasten umfasst, wobei das Ankoppelelement von einer Ebene, in der die Drehachse liegt und die senkrecht zu den Radachsen ist, beabstandet am Drehgestell angeordnet ist.The cradle bogie is characterized in that the cradle comprises at least one coupling element for further coupling a mechanical coupling device to a second car body, the coupling element being arranged on the bogie at a distance from a plane in which the axis of rotation lies and which is perpendicular to the wheel axles.

Dies bewirkt eine gute Anlenkung.This causes good guidance.

Die spezielle Elastizität des elastischen Elements, das hier als Sekundärfeder wirkt, hat den Vorteil, dass Unregelmäßigkeiten in einem Verlauf und/oder in einem Bogen eines Gleises gegenüber der mechanischen Kopplung in Form lateraler und/oder drehender Bewegung ausgeglichen werden. Dies führt zu weniger Verschleiß an Rädern und Gleis.The special elasticity of the elastic element, which acts here as a secondary spring, has the advantage that irregularities in a course and/or in a curve of a track are compensated for in relation to the mechanical coupling in the form of lateral and/or rotating movement. This leads to less wear and tear on the wheels and track.

Das Schienenfahrzeug umfasst einen ersten und einem zweiten Wagenkasten, der an einem Ankoppelpunkt gelenkig mit dem ersten Wagenkasten verbunden ist, und ein erfindungsgemäßes Wiegendrehgestell, welches so mit dem ersten Wagenkasten um die Drehachse drehbar verbunden ist, dass die Drehachse senkrecht zu einer Wagenkastenlängsachse des ersten Wagenkasten ist, die durch den Ankoppelpunkt verläuft und die Drehachse in einem Schnittpunkt schneidet. Dabei umfasst das Schienenfahrzeug eine mit einem ersten Ende an das Ankoppelelement und mit einem zweiten Ende an dem zweiten Wagenkasten angekoppelte Anlenkvorrichtung.The rail vehicle comprises a first and a second car body, which is articulated to the first car body at a coupling point, and a cradle bogie according to the invention, which is rotatably connected to the first car body about the axis of rotation in such a way that the axis of rotation is perpendicular to a longitudinal axis of the first car body which runs through the coupling point and intersects the axis of rotation at an intersection point. In this case, the rail vehicle comprises a coupling device coupled with a first end to the coupling element and with a second end to the second car body.

Das Wiegendrehgestell umfasst weiterhin zwei Paar Räder, wobei die Räder jeden Paars eine selbe Radachse aufweisen und die Radachsen der zwei Paare zueinander parallel in einer zur Drehachse senkrechten Achsebene angeordnet sind.The cradle bogie further comprises two pairs of wheels, the wheels of each pair having the same wheel axle and the wheel axles of the two pairs are arranged parallel to one another in an axial plane perpendicular to the axis of rotation.

Die Räder können Losräder sein oder jedes Paar kann einen Radsatz bilden. Dabei besteht ein Radsatz aus über eine Welle zur Übertragung von Drehmoment starr verbundenen Rädern.The wheels can be loose wheels or each pair can form a wheel set. A wheel set consists of wheels that are rigidly connected via a shaft to transmit torque.

Das Wiegendrehgestell kann weiterhin Achslager umfassen, in denen die Radachsen gelagert sind, wobei die Achslager mit dem Rahmen über weitere, als Primärfederung wirkende elastische Elemente verbunden sein können.The cradle bogie can also include axle bearings in which the wheel axles are mounted, it being possible for the axle bearings to be connected to the frame via other elastic elements acting as primary suspension.

Dies bewirkt eine besonders gute Federung.This causes a particularly good suspension.

Das elastische Element kann eine oder mehrere Federelemente umfassen, wobei jedes der Federelemente jeweils eine Elastomerfeder, eine Schraubenfeder und/oder eine hängend angeordnete Hydraulikfeder mit einer über eine Pendelwirkung erzielten Rückstellung umfassen kann.The elastic element can comprise one or more spring elements, each of the spring elements being able to comprise an elastomer spring, a helical spring and/or a hydraulic spring arranged in a suspended manner with a return achieved via a pendulum effect.

Dies sind einfach herstellbare Federelemente.These are spring elements that are easy to produce.

Alternativ oder zusätzlich kann das elastische Element zwei an äußeren Enden der Wiege angeordnete Federelemente umfassen, die die Selbstzentrierung unterstützen bzw. bewirken.Alternatively or additionally, the elastic element can comprise two spring elements which are arranged at the outer ends of the cradle and which support or bring about the self-centering.

Das zweite Ende kann beabstandet von dem Ankoppelpunkt an dem zweiten Wagenkasten angekoppelt sein.The second end can be coupled to the second car body at a distance from the coupling point.

Insbesondere kann das zweite Ende von dem Ankoppelpunkt in einer Richtung beabstandet an dem zweiten Wagenkasten angekoppelt sein, die senkrecht zur Fahrzeuglängsachse und senkrecht zur Drehachse ist.In particular, the second end can be coupled to the second car body at a distance from the coupling point in a direction which is perpendicular to the longitudinal axis of the vehicle and perpendicular to the axis of rotation.

Der Abstand kann proportional zu einem ersten weiteren Abstand zwischen dem Ankoppelelement und dem Schnittpunkt, einem zweiten weiteren Abstand des Ankoppelpunkts von der Drehachse und einem dritten weiteren Abstand des Ankoppelpunkts von einer zweiten Drehachse eines mit dem zweiten Wagenkasten um die zweite Drehachse drehbar verbundenen, zweiten Wiegendrehgestells sein.The distance can be proportional to a first further distance between the coupling element and the point of intersection, a second further distance of the coupling point from the axis of rotation and a third further distance of the coupling point from a second axis of rotation of a second cradle bogie connected to the second car body so as to be rotatable about the second axis of rotation.

Eine Länge der Anlenkvorrichtung kann einstellbar sein.A length of the articulation device can be adjustable.

Dies ermöglicht eine zwangsfreie Montage bei exakt ausgerichtetem Schienenfahrzeug.This enables assembly without constraint when the rail vehicle is precisely aligned.

The axle bearings 60 are connected to the frame via further elastic elements 70 (primary suspension). The other elastic elements 70 are elastic in the direction of the axis of rotation D. They compensate for unevenness in the track.

Im Ausführungsbeispiel fällt eine Symmetrieachse des elastischen Elements 20 mit der Drehachse zusammen.In the exemplary embodiment, an axis of symmetry of the elastic element 20 coincides with the axis of rotation.

Ist das elastische Element 20 unbelastet, so ist die Drehachse D senkrecht zu einer Achsebene A.If the elastic element 20 is unloaded, the axis of rotation D is perpendicular to an axis plane A.

Das elastische Element 20 ist jedoch elastisch bezüglich Drehung und/oder Kippen des Rahmens 30 relativ zur Wiege 10. Das heißt, das elastische Element 20 erlaubt ein Kippen der Drehachse D aus der Normale der Achsebene A und/oder eine Drehung des Rahmens 30 relativ zur Wiege 10.However, the elastic element 20 is elastic with respect to rotation and/or tilting of the frame 30 relative to the cradle 10 cradle 10

Das Wiegendrehgestell kann daher Unregelmäßigkeiten in einem Verlauf und/oder in einem realen Bogen eines Gleises gegenüber einer durch starre mechanische Anlenkung vorgegebenen Idealbogen ausweichen. Dies führt zu weniger Verschleiß an Rädern und Schiene.The weighing bogie can therefore avoid irregularities in a course and/or in a real curve of a track compared to an ideal curve predetermined by rigid mechanical linkage. This results in less wear and tear on the wheels and track.

Figur 2 zeigt ein erstes Ausführungsbeispiel eines erfindungsgemäßen Schienenfahrzeugs 200 in nicht ausgelenktem Zustand. Figur 3 zeigt das erste Ausführungsbeispiel des Schienenfahrzeugs 200 im ausgelenkten Zustand. figure 2 shows a first exemplary embodiment of a rail vehicle 200 according to the invention in the non-deflected state. figure 3 shows the first exemplary embodiment of the rail vehicle 200 in the deflected state.

Das Schienenfahrzeug 200 umfasst ein Ausführungsbeispiel des erfindungsgemäßen Wiegendrehgestells 100, einen ersten Wagenkasten 110, eine Anlenkvorrichtung 140 und einem Ankoppelpunkt 151 zum gelenkigen Ankoppeln an einen anderen, zweiten Wagenkasten. Im Ausführungsbeispiel ist der Ankoppelpunkt an einer Gelenkkonsole 150 vorgesehen. An dem Ankoppelpunkt 151 kann eine weitere Gelenkkonsole 160 des zweiten Wagenkastens des Schienenfahrzeugs oder eines zwischen dem Schienenfahrzeug und dem zweiten Wagenkasten des Schienenfahrzeugs angeordneten Fahrzeugteils ohne eigenes Drehgestell angekoppelt werden. Dies ist schematisch in Figuren 2 und 3 gezeigt.The rail vehicle 200 comprises an exemplary embodiment of the cradle bogie 100 according to the invention, a first car body 110, a coupling device 140 and a coupling point 151 for articulated coupling to another, second car body. In the exemplary embodiment, the coupling point is provided on an articulated bracket 150 . Another articulated bracket 160 of the second car body of the rail vehicle or of a vehicle part arranged between the rail vehicle and the second car body of the rail vehicle without its own bogie can be coupled to the coupling point 151 . This is schematic in Figures 2 and 3 shown.

Das Wiegendrehgestell 100 ist mit dem ersten Wagenkasten 110, beispielsweise an einem Verbindungspunkt V, verbunden. Die Drehachse D verläuft durch den Verbindungspunkt V und einen nicht in der Figur 2 gezeigten Schnittpunkt mit einer Fahrzeuglängsachse L. Die Fahrzeuglängsachse L verläuft senkrecht zur Drehachse D durch den Ankoppelpunkt 151. Der Verbindungspunkt V ist im Ausführungsbeispiel entlang einer Fahrzeugquerachse Q bezüglich des Wagenkastens 110 mittig angeordnet, die Erfindung ist jedoch nicht hierauf beschränkt. Die Fahrzeugquerachse Q ist senkrecht zur Fahrzeuglängsachse L und senkrecht zur Drehachse D.The weighing bogie 100 is connected to the first car body 110, for example at a connection point V. The axis of rotation D passes through the connection point V and not in the figure 2 shown intersection with a vehicle longitudinal axis L. The vehicle longitudinal axis L runs perpendicular to the axis of rotation D through the coupling point 151. In the exemplary embodiment, the connection point V is arranged centrally along a vehicle transverse axis Q with respect to the car body 110, but the invention is not limited to this. The transverse axis of the vehicle Q is perpendicular to the longitudinal axis of the vehicle L and perpendicular to the axis of rotation D.

Das Ankoppelelement 40 der Wiege des Wiegendrehgestells 100 ist von der Drehachse D beabstandet angeordnet. In den gezeigten Ausführungsbeispielen der Figuren 2 - 5 ist die Beabstandung in Richtung der Radachsen, dies ist jedoch nicht zwingend.The coupling element 40 of the cradle of the cradle bogie 100 is arranged at a distance from the axis of rotation D. In the exemplary embodiments shown Figures 2 - 5 is the spacing in the direction of the wheel axles, but this is not mandatory.

Ein Ende der Anlenkvorrichtung 140 ist mit dem Ankoppelelement 40 der Wiege des Wiegendrehgestells 100 verbunden. Das gegenüberliegende Ende der Anlenkvorrichtung 140 ist mit der weiteren Gelenkkonsole 160 an einem Anlenkpunkt 162 verbunden, der zum Ankoppelpunkt 151 einen Abstand B0 aufweist.One end of the linkage device 140 is connected to the coupling element 40 of the cradle of the cradle bogie 100 . The opposite end of the pivoting device 140 is connected to the further articulated bracket 160 connected to a pivot point 162, which has a distance B0 to the coupling point 151.

In Figur 2 ist eine Stirnfläche der weiteren Gelenkkonsole 160, an der der Anlenkpunkt 161 und der Ankoppelpunkt 151 angeordnet sind, parallel zur Fahrzeugquerachse Q. Die Anlenkvorrichtung 140 überträgt diese Lage auf die Wiege, die die Lage wiederum auf die Radachsen überträgt. Im idealen Gleis sind dann die Radachsen ebenfalls parallel zur Fahrzeugquerachse Q. Die Anlenkvorrichtung 140 ist ausgebildet, dass dann der Anlenkpunkt 161 in einer Richtung senkrecht zur Fahrzeuglängsachse L und senkrecht zur Drehachse D durch den Abstand B0 von dem Ankoppelpunkt 151 beabstandet ist.In figure 2 is an end face of the further joint bracket 160, on which the pivot point 161 and the coupling point 151 are arranged, parallel to the vehicle transverse axis Q. The pivot device 140 transmits this position to the cradle, which in turn transmits the position to the wheel axles. In the ideal track, the wheel axles are then also parallel to the vehicle transverse axis Q. The coupling device 140 is designed so that the coupling point 161 is spaced apart from the coupling point 151 by the distance B0 in a direction perpendicular to the vehicle longitudinal axis L and perpendicular to the axis of rotation D.

In Figur 3 ist die weitere Gelenkkonsole 160 nicht parallel zur Fahrzeugquerachse Q. Die Anlenkvorrichtung 140 überträgt diese Lage auf die Wiege, die die Lage wiederum auf die Radachsen überträgt. Im idealen Gleis sind dann die Radachsen ebenfalls nicht parallel zur Fahrzeugquerachse Q.In figure 3 the other articulated bracket 160 is not parallel to the vehicle transverse axis Q. The articulation device 140 transmits this position to the cradle, which in turn transmits the position to the wheel axles. In the ideal track, the wheel axles are also not parallel to the transverse axis Q of the vehicle.

Die Konizität der Räder bewirkt grundsätzlich die Selbstzentrierung im Gleis. Die Elastizität des elastischen Elements erlaubt dabei den Rädern bzw. Radsätzen, Abweichungen vom idealen Gleis zu kompensieren. Daher können die Abweichungen die Selbstzentrierung nicht stören. Die Räder bzw. Radsätze laufen so verschleißarm im realen Gleis trotz Anlenkung entsprechend einem idealisierten Gleisverlauf und/oder -bogen. Insbesondere im Bereich des Bogenein- und -auslaufs sind solche Abweichungen stets gegeben und können erfindungsgemäß kompensiert werden.The conicity of the wheels basically causes the self-centering in the track. The elasticity of the elastic element allows the wheels or wheel sets to compensate for deviations from the ideal track. Therefore, the deviations cannot disturb the self-centering. In this way, the wheels or wheelsets run with little wear on the real track, despite the linkage corresponding to an idealized track course and/or curve. In particular in the area of the sheet infeed and outfeed, such deviations are always present and can be compensated according to the invention.

In den Figuren 2 und 3 ist die Anlenkung einseitig. Die Anlenkvorrichtung 140 ist an einem Ankoppelelement 40 angekoppelt und dient zur Verbindung mit der weiteren Gelenkkonsole 160 des am ersten Wagenkasten gelenkig angekoppelten zweiten Wagenkasten des Schienenfahrzeugs.In the Figures 2 and 3 the linkage is one-sided. The articulation device 140 is coupled to a coupling element 40 and is used for connection to the further articulated bracket 160 of the second car body of the rail vehicle, which is articulated to the first car body.

In den Figuren 4 und 5 hingegen ist die Anlenkung zweiseitig. Zusätzlich zur Anlenkvorrichtung 140 ist eine weitere Anlenkvorrichtung 141 an einem weiteren Ankoppelelement 41 angekoppelt und dient zur weiteren Verbindung mit der weiteren Gelenkkonsole 160. Ein Abstand B1 des weiteren Ankoppelelements 41 von der Drehachse D gleich dem Abstand des Ankoppelelements 40 von der Drehachse D. Dabei ist im Ausführungsbeispiel das weitere Ankoppelelement 41 bezüglich der Drehachse D gegenüberliegend zum Ankoppelelement 40 angeordnet.In the Figures 4 and 5 however, the linkage is bilateral. In addition to the articulation device 140, a further articulation device 141 is coupled to a further coupling element 41 and is used for further connection to the further joint bracket 160. A distance B1 of the further coupling element 41 from the axis of rotation D is equal to the distance of the coupling element 40 from the axis of rotation D in the exemplary embodiment, the further coupling element 41 is arranged opposite the coupling element 40 with respect to the axis of rotation D.

Die gegenüberliegende Anordnung ist jedoch optional. Beispielsweise ist auch eine Anordnung möglich, die symmetrisch bezüglich einer Längsachse des Drehgestells ist, die senkrecht zur Drehachse und den Radachsen verläuft.However, the opposite arrangement is optional. For example, an arrangement is also possible that is symmetrical with respect to a longitudinal axis of the bogie, which runs perpendicular to the axis of rotation and the wheel axles.

Um einen Ausdrehwinkel α des Wiegendrehgestells zu bewirken, muss ein Ausdrehweg s am Ankoppelelement 40 realisiert werden. Dabei gilt: s = 2*B1*π*α/360°. Dabei entsprechen 2*π und 360° jeweils dem Vollkreis.In order to bring about a rotation angle α of the cradle bogie, a rotation path s must be implemented on the coupling element 40 . The following applies: s = 2*B1*π*α/360°. 2*π and 360° each correspond to a full circle.

Die Erfindung eignet sich beispielsweise für Niederflurstraßenbahnen mit über eine Wiege im mittleren Fahrzeugteil an den Wagenkasten angebundenen Losraddrehgestell. Dabei kann für die Anbindung der Wiege an den Wagenkasten weiterhin ein Wälzkörperdrehlager oder Drehzapfen in Kombination mit Auflager-Gleitplatten zum Einsatz kommen.The invention is suitable, for example, for low-floor trams with a loose-wheel bogie connected to the car body via a cradle in the middle part of the vehicle. To connect the cradle to the car body, a rolling element pivot bearing or pivot in combination with bearing sliding plates can still be used.

Ein geeigneter Abstand B0 des Anlenkpunkts 161 vom Ankoppelpunkt 151 lässt sich über einen Gelenkwinkel β wie folgt bestimmen: B0 = s*360°/(2*β*π). Dabei ist die Relation des Gelenkwinkels β(R) zu einem Radius R des Gleisbogens durch einen Konstrukteur des Schienenfahrzeugs weitgehend frei wählbar.A suitable distance B0 of the pivot point 161 from the coupling point 151 can be determined via a joint angle β as follows: B0=s*360°/(2*β*π). The relation of the joint angle β(R) to a radius R of the curved track can be largely freely selected by a designer of the rail vehicle.

Dies kann speziell bei Einrichtungsfahrzeugen ausgenutzt werden. Bei Einrichtungsfahrzeugen kann es nämlich vorteilhaft sein, den Abstand des Anlenkpunkts eines vorlaufenden Drehgestells größer als den Abstand des Anlenkpunkts eines nachlaufenden Drehgestells zu wählen. So kann speziell bei Radsatzdrehgestellen einem Anlaufen an der Außenschiene entgegengewirkt werden, welches sich aus der Drehfreiheit des elastischen Elements und dem durch die Radsätze entwickelten Wendemoment ergibt. Die Abstände der Anlenkpunkte sind vorteilhaft so gewählt, dass beim vorlaufenden äußeren Rad ein Anlaufen des Radrückens an der Leitkante vermieden wird.This can be used specifically for one-way vehicles. In the case of one-way vehicles, it can be advantageous to make the distance between the pivot point of a leading bogie greater than the distance between the pivot point of a trailing one bogie to choose. In this way, especially in the case of wheelset bogies, contact with the outer rail can be counteracted, which results from the freedom of rotation of the elastic element and the turning moment developed by the wheelsets. The distances between the pivot points are advantageously selected in such a way that the leading outer wheel does not touch the rear of the wheel on the leading edge.

Die in den Ausführungsbeispielen gezeigte Anlenkung des Wiegendrehgestells ist beispielhaft. Andere Anlenkungen der Wiege sind möglich.The articulation of the cradle bogie shown in the exemplary embodiments is exemplary. Other articulations of the cradle are possible.

Die Sekundärfeder der Ausführungsbeispiele ist eine einzelne Elastomerfeder. Je nach Breite und Höhe des Einbauraumes kann auch ein Elastomerfederpaar verwendet werden. Alternativ oder zusätzlich können Schraubenfeder(n) und/oder hängend angeordnete Hydraulikfeder(n) mit einer über eine Pendelwirkung erzielten Rückstellung verwendet werden.The secondary spring of the exemplary embodiments is a single elastomeric spring. Depending on the width and height of the installation space, a pair of elastomer springs can also be used. Alternatively or additionally, helical spring(s) and/or hydraulic spring(s) arranged in a hanging manner can be used with a return achieved via a pendulum effect.

Die Wiege kann gekröpft ausgeführt sein. Ein Drehlager kann eine Anbindung der Wiege an den Wagenkasten zur Verfügung stellen. Dabei kann eine seitliche Abstützung über Gleitplatten erfolgen.The cradle can be cranked. A rotary bearing can provide a connection between the cradle and the car body. Lateral support can be provided by sliding plates.

Ein Ausführungsbeispiel der Erfindung umfasst den Einsatz einer Wiegenpositionierung in Abhängigkeit von einer Wagenkastenstellung im Bogen zur Erzielung einer idealisierten Mittellage und elastische Anpassung der Radpaare an die tatsächlichen Gegebenheiten im Gleis. Rückstellkräfte des elastischen Elements bewirken eine Zentrierung, die den Rahmen immer wieder in eine zur Gleisachse parallele Lage zurückführt und so den Radpaaren fehlerfreien Schienenkontakt ermöglicht. Obwohl die Erfindung im Detail durch bevorzugte Ausführungsbeispiele näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den durch die beiliegenden Ansprüche definierten Schutzumfang der Erfindung zu verlassen.An embodiment of the invention includes the use of a cradle positioning depending on a car body position in the curve to achieve an idealized center position and elastic adjustment of the wheel pairs to the actual conditions on the track. Restoring forces of the elastic element cause centering, which always returns the frame to a position parallel to the axis of the track and thus enables the wheel pairs to make perfect contact with the rails. Although the invention has been illustrated and described in detail by means of preferred embodiments, the invention is not limited by the disclosed examples and other variations can be derived therefrom by those skilled in the art without departing from the protective scope of the invention as defined by the appended claims.
