Abstract

The triple axle bogey construction has the three axles and attached drive motors (16,17,18) mounted between the parallel supports (2,3) of the bogey. The outer two wheel units have their axle bearings adjustable longitudinally (x1-x2) to adapt to curves. The central wheel unit has axial movement (y1-y2) on its bearings to enable a servo (22) to move the wheel unit in either direction and obtain good tracking during cornering. The middle wheel unit servo is a double acting ram and is controlled by the centrifugal force on the bogey. This spreads the reaction force of the wheels on the outer rail of the curve. The displacement can also be controlled w.r.t. curvature of the rails. <IMAGE>

Description

Die Erfindung bezieht sich auf ein selbstlenkendes dreiachsiges Laufwerk für ein Schienenfahrzeug gemäß den Oberbegriffen der nebengeordneten Ansprüche 1 und 2.The invention relates to a self-steering three-axle Drive for a rail vehicle according to the generic terms of independent claims 1 and 2.

Aus der DE 41 40 126 A1 ist ein Laufwerk für Schienenfahrzeuge mit drei angetriebenen Radsätzen bekannt, die in einem Drehgestell- oder Fahrzeugrahmen elastisch gelagert sind und bei dem durch ein Lenkgestänge die sich bei Bogenfahrt einstellenden Drehbewegungen des ersten Radsatzes und des dritten Radsatzes um vertikale Achsen mit der durch Längslenker geführten Querbewegung des zweiten Radsatzes gekoppelt sind. An den Radsatzlagergehäusen des ersten Radsatzes und des dritten Radsatzes sind in Richtung auf den zweiten Radsatz weisende, parallel zur Fahrzeuglängsmitte verlaufende Lenkerstangen gelenkig befestigt, deren jeweils vom Radsatzlager abgewandtes Ende an den zur Fahrzeuglängsmitte weisenden Armen von außen am Drehgestell- oder Fahrzeugrahmen gelagerten Winkelhebeln gelenkig befestigt sind, deren in Richtung auf den zweiten Radsatz weisende Arme jeweils durch eine in Querrichtung verlaufende Koppelstange gelenkig miteinander verbunden sind. Die jeweils in Richtung auf den zweiten Radsatz verlängerten Arme der zueinander diagonal versetzt angeordneten Winkelhebel sind über außen am Drehgestell- oder Fahrzeugrahmen gelagerte und in Fahrzeuglängsrichtung verlaufende Doppelhebel mit den Stirnseiten der Radsatzlagergehäuse des zweiten Radsatzes gelenkig miteinander verbunden.DE 41 40 126 A1 is a running gear for rail vehicles known with three driven wheel sets which are elastically mounted in a bogie or vehicle frame and in which through a steering linkage that arises when driving through bends Rotational movements of the first wheel set and the third wheel set around vertical axes with the transverse movement guided by trailing arms of the second wheel set are coupled. On the wheelset bearing housings of the first wheelset and the third wheelset are in Direction pointing to the second wheel set, parallel to the longitudinal center of the vehicle extending handlebars articulated, whose each end facing away from the wheelset bearing to the center of the vehicle pointing arms from the outside on the bogie or Vehicle frame mounted angle levers are articulated, their arms pointing towards the second wheel set articulated by a coupling rod running in the transverse direction are interconnected. Each in the direction of the second wheelset extended arms which are offset diagonally to each other arranged angle levers are on the outside of the bogie or Vehicle frame mounted and running in the vehicle longitudinal direction Double lever with the end faces of the wheelset bearing housings of the second wheel set articulated together.

Aus der DE-A-41 42 255 ist ein Laufwerk für Schienenfahrzeuge mit radialer Steuerung der Radsätze bekannt, bei dem die Querbewegung des mittleren Radsatzes mittels eines Hebels auf die Schräglenker der Endradsätze übertragen wird, so daß die zwischen den Endradsätzen liegenden Radsätze so gesteuert werden, daß sie Fliehkräfte auf die Außenschiene übertragen.From DE-A-41 42 255 is a drive for rail vehicles with radial control of the wheel sets known, in which the transverse movement the middle wheel set with a lever on the semi-trailing arm the end gear sets is transmitted so that between the end gear sets lying wheel sets are controlled so that they are centrifugal forces transferred to the outer rail.

Der Erfindung liegt die Aufgabe zugrunde, ein selbstlenkendes dreiachsiges Laufwerk für ein Schienenfahrzeug der eingangs genannten Art anzugeben, bei dem die eine Querbewegung des Mittelradsatzes behindernden horizontalen Rückstellkräfte der Primärfedern überwunden werden.The invention has for its object a self-steering triaxial running gear for a rail vehicle of the type mentioned Specify the way in which a transverse movement of the center wheel set hindering horizontal restoring forces of the primary springs be overcome.

Diese Aufgabe wird alternativ in Verbindung mit den Merkmalen der Oberbegriffe erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 und 2 angegebenen Merkmale gelöst.This task is alternatively used in conjunction with the features of General terms according to the invention by the in the characterizing part of the claim 1 and 2 specified features solved.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß ein selbstlenkendes, dreiachsiges Laufgestell für ein Schienenfahrzeug geschaffen wird, bei dem auch der Mittelradsatz durch Fliehkraft bedingte Seitenkräfte auf die Schienen überträgt, und bei dem dadurch die durch Fliehkraft bedingten Seitenkräfte auf die Außenradsätze vermindert werden. Bei geeigneter Beaufschlagung des aktiven Stellgliedes wirkt auf jeden Radsatz je ein Drittel Fliehkraftanteil. Gleichzeitig werden die der Steuerbewegung entgegenstehenden, eine Querbewegung des Mittelradsatzes und Drehbewegungen der Endradsätze behindernden horizontalen Rückstellkräfte der Primärfedern überwunden. Allgemein gilt für das selbstlenkende dreiachsige Laufwerk, daß alle drei Radsätze zur Steuerung bei Kurvenfahrt herangezogen werden. Durch die aktive Mitwirkung des Mittelradsatzes am Steuerungssystem wird inbesondere bei kleinen Bogenradien, bei denen für die radiale Stellung größere horizontale Auslenkungen der Radsatzfedern erforderlich werden, die Ausrichtung der Radsätze zur Bogenmitte verbessert. Weitere Vorteile sind aus der Beschreibung ersichtlich. The advantages that can be achieved with the invention are in particular in that a self-steering, three-axle bogie for a Rail vehicle is created, which also includes the center wheel set transfers lateral forces to the rails due to centrifugal force, and thereby the lateral forces caused by centrifugal force be reduced to the outer wheel sets. With suitable application of the active actuator acts on each wheel set Third part of centrifugal force. At the same time, those of the tax movement opposing, a transverse movement of the center gear set and rotational movements of the end wheel sets hindering horizontal restoring forces of the primary springs overcome. Generally applies to that self-steering three-axle drive that all three wheelsets for Control can be used when cornering. Through the active Participation of the center wheel set on the control system is particularly with small arc radii, with those for the radial position Larger horizontal deflections of the wheelset springs required the alignment of the wheel sets to the center of the curve is improved. Further advantages are evident from the description.

Die Erfindung wird nachstehend anhand der in der Zeichnung dargestellten Ausführungsbeispiele erläutert. Es zeigen:

Figur 1
ein erste Ausführungsform mit aktivem Stellglied zwischen Mittelradsatz und Drehgestell,
Figur 2
eine zweite Ausführungsform mit aktivem Stellglied zwischen Mittelradsatz und Fahrzeugkasten.
The invention is explained below with reference to the embodiments shown in the drawing. Show it:
Figure 1
a first embodiment with an active actuator between the center wheel set and the bogie,
Figure 2
a second embodiment with an active actuator between the center wheel set and the vehicle body.

Durch Radialsteuerung werden die im Bogen die durch die Reibung Rad/Schiene verursachten Seitenkräfte vermindert bzw. im Idealfall vermieden. Seitenkräfte durch Fliehkraft oder Abtriebsüberschuß im Bogen müssen in jedem Fall von den Radsätzen (Achsen) auf das Gleis übertragen werden. Bei dreiachsigen Drehgestellen (Laufgestellen) wird die Fliehkraft nur von den Endradsätzen (Außenradsätze) übertragen, da diese die Führung im Bogen ausführen. Während beim zweiachsigen Drehgestell jeder Radsatz den der Radsatzlast entsprechenden Fliehkraftanteil überträgt, muß beim dreiachsigen Drehgestell jeder Endradsatz etwa die Hälfte der durch Fliehkraft verursachten Seitenkräfte übertragen, wenn keine besonderen Vorkehrungen getroffen werden, damit auch der Mittelradsatz den der Radsatzlast entsprechenden Fliehkraftanteil überträgt.By radial control, those in the arc are caused by the friction Wheel / rail side forces are reduced or ideally avoided. Lateral forces due to centrifugal force or excess downforce in the bow must in any case from the wheelsets (axles) be transferred to the track. With three-axle bogies (Undercarriages) the centrifugal force is only from the end wheel sets (Outer wheel sets) as these perform the guidance in the curve. While on the biaxial bogie, each wheelset transfers the corresponding centrifugal force to the axle load for the three-axle bogie, each end wheel set is about half of the lateral forces caused by centrifugal force if no special precautions are taken so that the Center gear set the centrifugal force corresponding to the wheel set load transmits.

In Figur 1 ist ein Drehgestell mit aktivem Stellglied zwischen Mittelradsatz und Drehgestell dargestellt, wobei eine solche Verlagerung des Fliehkraftanteils auf den Mittelradsatz erfolgt, daß alle drei Radsätze je ein Drittel der durch Fliehkraft verursachten Seitenkräfte auf die Schienen übertragen.In Figure 1 is a bogie with an active actuator between Center wheel set and bogie shown, such The centrifugal force component is shifted to the center wheel set, that all three wheel sets each a third of those caused by centrifugal force Transfer lateral forces to the rails.

Es ist die Sicht auf ein selbstlenkendes, dreiachsiges mit dem Fahrzeugkasten eines Schienenfahrzeuges beweglich verbundenes Drehgestell 1 gezeigt. Das Drehgestell 1 weist einen aus parallelen Längsträgern 2, 3 und parallelen Querträgern 4, 5 bestehenden Drehgestellrahmen auf. An den Längsträgern 2, 3 sind Radsatzlager 6 bis 11 der drei Achsen 12 bis 14 über nicht dargestellte Radsatzfedern befestigt, und zwar Radsatzlager 6, 7 für die erste, dem ersten Antriebsmotor 16 zugeordnete Achse 12 (Außenachse, Außenradsatz), Radsatzlager 8, 9 für die zweite (mittlere), dem zweiten (mittleren) Antriebsmotor 17 zugeordnete Achse 13 (Mittelradsatz) und Radsatzlager 10, 11 für die dritte, dem dritten Antriebsmotor 18 zugeordnete Achse 14 (Außenachse, Außenradsatz). Radsatzlager 9 ist in Figur 1 nicht zu erkennen, jedoch in Figur 2 dargestellt.It is the view of a self-steering, three-axis with the Vehicle body of a rail vehicle movably connected Bogie 1 shown. The bogie 1 has one of parallel Side members 2, 3 and parallel cross members 4, 5 existing Bogie frame on. On the side members 2, 3 are Wheelset bearings 6 to 11 of the three axes 12 to 14 via not shown Wheelset springs attached, namely wheelset bearings 6, 7 for the first axis 12 assigned to the first drive motor 16 (Outer axle, outer wheel set), wheelset bearings 8, 9 for the second (middle), assigned to the second (middle) drive motor 17 Axle 13 (center wheel set) and wheel set bearings 10, 11 for the third, axis 14 assigned to the third drive motor 18 (outer axis, Outer wheel set). Wheelset bearing 9 cannot be seen in FIG. 1, however shown in Figure 2.

Die Radsatzlager 6, 7, 10, 11 der beiden Außenachsen 12, 14 sind unter anderem in Richtung parallel zu den Längsträgern 2, 3 des Drehgestellrahmens, d.h. in Fahrtrichtung bzw. entgegen der Fahrtrichtung des Schienenfahrzeuges beweglich, was durch Richtungspfeile x1, x2 jeweils angedeutet ist. Die Radsatzlager 8, 9 der mittleren Achse 13 sind unter anderem in Richtung parallel zu den Querträgern 4, 5 des Drehgestellrahmens, d.h. senkrecht zur Fahrtrichtung des Schienenfahrzeuges beweglich, was durch Richtungspfeile y1, y2 jeweils angedeutet ist.The wheelset bearings 6, 7, 10, 11 of the two outer axles 12, 14 are inter alia in the direction parallel to the longitudinal beams 2, 3 of the Bogie frame, i.e. in the direction of travel or against Direction of travel of the rail vehicle is movable, which is indicated by directional arrows x1, x2 is indicated in each case. The wheelset bearings 8, 9 the central axis 13 are parallel, among other things, in the direction to the cross beams 4, 5 of the bogie frame, i.e. perpendicular movable to the direction of travel of the rail vehicle, what by Direction arrows y1, y2 is indicated in each case.

Die durch Tatzlagermotoren 16 bis 18 angetriebenen Laufräder sind mit 15 bezeichnet.The impellers driven by Tatzlagermotoren 16 to 18 are denoted by 15.

Es ist ein Steuerzylinder 22 (allgemein: aktives Stellglied) vorgesehen, dessen beweglicher Kolben 21 über eine Kolbenstange 20 mit einem Gelenk 19 am Mittelradsatz 13, 8, 9 - z.B. am Antriebsmotor 17 - angreift. Der Steuerzylinder 22 ist andererseits über eine Verbindungsstange 23 mit einem Gelenk 24 am Längsträger 3 des Drehgestellrahmens befestigt.It is a control cylinder 22 (generally: active actuator) provided, the movable piston 21 via a piston rod 20 with a joint 19 on the center wheel set 13, 8, 9 - e.g. on the drive motor 17 - attacks. The control cylinder 22 is on the other hand via a connecting rod 23 with a joint 24 on Side member 3 of the bogie frame attached.

Beim quer zur Fahrtrichtung wirksamen Steuerzylinder 22 handelt es sich z.B. um einen doppeltwirkenden Druckluft- oder Hydraulikzylinder. Über Verbindungsleitungen kann der Steuerzylinder in geeigneter Weise druckbeaufschlagt werden, so daß über den Kolben 21 und die Kolbenstange 20 eine zusätzliche Druckkraft bzw. Zugkraft zwischen Mittelradsatz und Drehgestell ausgeübt wird, die den Mittelradsatz zusätzlich nach bogenaußen drückt bzw. zieht. Die Steuerung des Steuerzylinders 22 erfolgt in Abhängigkeit der auftretenden Fliehkraft und/oder des Bogenradius. Hierdurch belastet das aktive Stellglied (Steuerzylinder) den Mittelradsatz mit einem Fliehkraftanteil und entlastet entsprechend die Endradsätze.When the control cylinder 22 acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder. The control cylinder can be connected via connecting lines be pressurized in a suitable manner so that the Piston 21 and the piston rod 20 an additional pressure force or tractive force exerted between the center wheel set and the bogie that additionally pushes the center wheel set towards the outside of the bend or pulls. The control cylinder 22 is controlled in Dependence of the centrifugal force and / or the radius of the arc. As a result, the active actuator (control cylinder) the center wheel set with a centrifugal force component and relieved the end wheel sets accordingly.

Durch den Steuerzylinder zwischen Mittelradsatz und Drehgestellrahmen ergibt sich folgender vorteilhafter Zusatzeffekt: Die Rückstellwirkung der Primärfedern, die der Bogeneinstellung aller drei Radsätze entgegensteht und die durch die Reibkräfte zwischen Rad und Schiene nur bei größeren Bogenradien überwunden werden kann, wird durch die Stellkraft gleichfalls überwunden. Through the control cylinder between the center wheel set and the bogie frame the following advantageous additional effect results: The return effect of the primary springs, that of the bow adjustment of all three sets of wheels is opposed by the frictional forces overcome between wheel and rail only with larger radii of curvature can also be overcome by the actuating force.

Die Stellkraft muß dann nur entsprechend höher sein als der Fliehkraftanteil des Mittelradsatzes.The actuating force then only has to be correspondingly higher than that Centrifugal force share of the center wheel set.

Bei Bogenfahrt mit hohem Beschleunigungsüberschuß bewirkt die Fliehkraft eine quasi statische Auslenkung der Querfederung zwischen Fahrzeugkasten und Drehgestell. Diese erschöpft unter Umständen das Querspiel, so daß für dynamische Querbewegungen infolge Gleisfehlern das Querschwingspiel eingeschränkt ist oder sogar der Queranschlag erreicht wird, was die Laufgüte horizontal verschlechtert. Eine Vergrößerung des Querspiels schränkt die Fahrzeugbreite ein.When cornering with a high acceleration surplus, this causes Centrifugal force a quasi static deflection of the transverse suspension between Vehicle body and bogie. This may exhaust you the cross game, so that for dynamic transverse movements as a result Track errors, the transverse swing play is restricted or even the cross stop is achieved, making the running quality horizontal worsened. An increase in the cross game limits the vehicle width.

In Figur 2 ist ein Drehgestell mit aktivem Stellglied zwischen Mittelradsatz und Fahrzeugkasten dargestellt, wobei die bei Fliehkraftüberschuß auftretende quasi statische Querauslenkung zwischen Fahrzeugkasten und Drehgestell vermieden oder verringert wird. Gleichzeitig wird der Mittelradsatz zur Übertragung von Fliehkraft auf das Gleis herangezogen, um die beiden Endradsätze zu entlasten.In Figure 2 is a bogie with an active actuator between Center wheel set and vehicle body shown, the at Quasi static transverse deflection occurring at centrifugal force avoided or reduced between the vehicle body and the bogie becomes. At the same time, the center wheel set becomes a transmission by centrifugal force on the track around the two end wheel sets to relieve.

Das Laufgestell 1 weist alle vorstehend unter Figur 1 beschriebenen Baukomponenten 2 bis 18 auf, nicht jedoch die Baukomponenten 19 bis 24 auf. Es ist ein Steuerzylinder 28 vorgesehen, dessen beweglicher Kolben 27 über eine Kolbenstange 26 mit einem Gelenk 25 am Mittelradsatz 13, 8, 9 - z.B. am Antriebsmotor 17 - angreift. Der Steuerzylinder (allgemein: aktives Stellglied) 28 ist andererseits über eine Verbindungsstange 29 mit einem Gelenk 30 am Fahrzeugkasten 31 befestigt.The bogie 1 has all of those described above in FIG. 1 Components 2 to 18, but not the components 19 to 24. A control cylinder 28 is provided, the movable piston 27 via a piston rod 26 with a Joint 25 on the center wheel set 13, 8, 9 - e.g. on the drive motor 17 - attacks. The control cylinder (generally: active actuator) 28 is on the other hand via a connecting rod 29 with a joint 30 attached to the vehicle body 31.

Beim quer zur Fahrtrichtung wirksamen Steuerzylinder 28 handelt es sich z.B. um einen doppeltwirkenden Druckluft- oder Hydraulikzylinder. Über Verbindungsleitungen kann der Steuerzylinder in geeigneter Weise druckbeaufschlagt werden, so daß über den Kolben 27 und die Kolbenstange 26 eine zusätzliche Druckkraft bzw. Zugkraft zwischen Mittelradsatz und Fahrzeugkasten ausgeübt wird, die den Fahrzeugkasten nach bogeninnen drückt bzw. zieht. Die Steuerung des Steuerzylinders 28 erfolgt in Abhängigkeit der auftretenden Fliehkraft und/oder des Bogenradius. Hierdurch belastet das aktive Stellglied (Steuerzylinder) den Mittelradsatz mit einem Fliehkraftanteil und entlastet entsprechend die Endradsätze. Die Reaktionskraft wirkt auf den Fahrzeugkasten und vermindert die Auslenkung der Querfederung.When the control cylinder 28 acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder. The control cylinder can be connected via connecting lines be pressurized in a suitable manner so that the Piston 27 and the piston rod 26 an additional pressure force or tractive force exerted between the center wheel set and the vehicle body that pushes or pulls the vehicle body inwards. The control cylinder 28 is controlled as a function of centrifugal force and / or the radius of the arc. Hereby the active actuator (control cylinder) loads the center wheel set with a centrifugal force component and relieves the End wheel sets. The reaction force acts on the vehicle body and reduces the deflection of the transverse suspension.

Die Steuerkrafthöhe entspricht dem vom Mittelradsatz zu übertragenden Fliehkraftanteil zuzüglich der Federkraft zur Drehauslenkung der Endradsätze und der Federkraft des Mittelradsatzes, die durch die Pfeilhöhe des Gleisbogens zwischen den Endradsätzen entsteht.The amount of steering force corresponds to that to be transmitted from the center wheel set Centrifugal force component plus the spring force for turning the end gear sets and the spring force of the center gear set by the arrow height of the track arch between the end wheel sets arises.

Der Anteil der möglichen Rückstellung der Fliehkraftauslenkung Fahrzeugkasten/Drehgestell ist vom Drehgestellgewicht im Verhältnis zum Fahrzeugkasten, vom Bogenradius und von der horizontalen Rückstellkraft der Radsatzfedern abhängig. Je schwerer das Drehgestell, je enger der Bogen (je größer die Pfeilhöhe), je höher die horizontale Steifigkeit der Radsatzfedern, um so größer ist der Anteil der möglichen Verminderung der quasi statischen Querauslenkung. Dabei wird davon ausgegangen, daß die Fliehkraftbelastung der Radsätze gleich ist.The share of the possible provision of the centrifugal deflection Vehicle body / bogie is in relation to the bogie weight to the vehicle body, from the arc radius and from the horizontal Return force of the wheelset springs dependent. The harder it is Bogie, the narrower the bow (the greater the arrow height), each the higher the horizontal rigidity of the wheelset springs, the greater is the proportion of the possible reduction of the quasi static Transverse deflection. It is assumed that the Centrifugal load on the wheel sets is the same.

Wird die Fliehkraftbelastung des Mittelradsatzes jedoch höher gewählt als die der Endradsätze, was wegen seiner geringeren dynamischen Querbeanspruchung möglich ist, so kann die Rückstellung der Fliehkraftauslenkung weiter gesteigert werden. Damit kann ein Optimum an Rückstellung der Fliehkraftauslenkung, Verteilung der Fliehkraft auf die drei Radsätze und Radialstellung der Radsätze erreicht werden.However, the centrifugal load on the center wheel set becomes higher chosen as that of the final wheelsets, which is because of its lower dynamic Cross loading is possible, so the provision the centrifugal deflection can be further increased. In order to can provide an optimum in resetting the centrifugal deflection, distribution the centrifugal force on the three wheel sets and radial position of the wheel sets can be reached.

Es ist auch möglich, beide Maßnahmen gemäß Figur 1 und Figur 2 beim Drehgestell eines selbstlenkenden, dreiachsigen Schienenfahrzeuges vorzusehen.It is also possible to take both measures according to FIG. 1 and FIG. 2 on the bogie of a self-steering, three-axle rail vehicle to provide.

In den vorstehend erläuterten Ausführungsbeispielen wird stets von einem mit Tatzlagermotoren angetriebenen dreiachsigen Drehgestell für eine Lokomotive ausgegangen. Bei Antrieben, die nicht seitenfest mit dem Mittelradsatz verbunden sind und bei nichtangetriebenem Mittelradsatz oder nichtangetriebenem Drehgestell werden die aktiven Stellglieder gelenkig mit einem Befestigungsteil, das auf dem mittleren Radsatz gelagert ist, verbunden.In the exemplary embodiments explained above, always from a three-axle bogie driven by Tatzlager motors went out for a locomotive. For drives that are not laterally connected to the center wheel set and at non-driven center wheel set or non-driven bogie the active actuators become articulated with a fastening part, which is mounted on the middle wheelset connected.
