Abstract

In a guiding mechanism for radially controlling in a curve the wheelsets of rail vehicle bogies, both wheelsets are interconnected by two Z-shaped controlling means arranged each on one outer side of the bogie frame. The controlling means co-operate with the underframe, to which they are connected by joints. The controlling means (11, 11') are mounted each in a first vertical plane on both sides of the bogie frame (3) and at least one joint (21, 21') is arranged parallel to each controlling means in a second vertical plane offset towards the inside of the bogie frame (3). The wheelsets (5, 5') are radially adjusted in a curve exclusively on the basis of the torsion angle created between bogie (1) and underframe (4) when a curve is taken, regardless of the state of wear of the rails. The combination of controlling means (11, 11') mounted in a first vertical plane and of joints (21, 21') mounted in a second vertical plane allows the wheelsets to be controlled independently of the state of wear of the rails and strongly reduces the wear of wheel and rail flanges caused by guiding forces in the case of an automatic control.

Description

Lenkmechanismus zur kurvenradialen Steuerung der Radsätze von Fahrwerken bei Schienenfahrzeugen Steering mechanism for the radial control of the wheel sets of running gear in rail vehicles
Die Erfindung bezieht sich auf ein Fahrwerk mit einem Lenkmechanismus zur kurvenradialen Steuerung der Radsätze unabhängig vom Verschleisszustand der Schienen, wobei der Lenkmechanismus die beiden Radsätze sowohl untereinander, als auch mit dem Wagenkasten so verbindet, dass die Ausdrehwinkel der gummielastischen Lager in den Gelenkpunkten möglichst klein bleiben und dass die Anlenkung am Wagenkasten möglichst raumsparend erfolgt und eine gute Entkoppelung aufweist.The invention relates to a chassis with a steering mechanism for the radial control of the wheel sets regardless of the wear condition of the rails, the steering mechanism connecting the two wheel sets both to one another and to the car body in such a way that the angle of rotation of the rubber-elastic bearings in the articulation points remain as small as possible and that the articulation on the car body is as space-saving as possible and has good decoupling.
Durch die EP - PS 0 389 582 ist ein Drehgestell offenbart, bei dem die Radsätze in einer ersten Ausführungsform zur gegenseitigen Selbststeuerung zwecks radialer Einstellung durch eine vertikal am Drehgestellrahmen angeordnete Selbststeuereinrichtung untereinander verbunden sind.EP-PS 0 389 582 discloses a bogie in which, in a first embodiment, the wheel sets are connected to one another for mutual self-control for the purpose of radial adjustment by a self-control device arranged vertically on the bogie frame.
Bekanntermassen ist für ein verschleissfreies kinematisches Abrollen eines Radsatzes im Gleisbogen in Abhängigkeit des Abstandes seiner Radaufstandspunkte eine bestimmte Differenz der Abroll - Radien erforderlich. Rotationsfreiheit des Radsatzes und Radiendifferenz sind damit neben einem ausreichenden Kraftschlussbeiwert die Voraussetzungen, die für eine radiale Einstellung der Radsätze im Bogen erfüllt sein müssen. Jüngste Untersuchungen haben zudem gezeigt, dass für selbststeuemde Radsätze unter der Annahme eines verschleissangepassten Radprofils ein bestimmtes Schienenprofil vorauszusetzen ist, bei dessen Paarung die in Funktion des Bogenhalbmessers erforderliche Rollradiusdifferenz aufgebaut werden kann. Dieses ideelle Schienenprofil ist aufgrund unterschiedlicher Verschleisszustände auf einem Streckennetz kaum vorhanden bzw. wirtschaftlich nicht instandzuhalten. Darüber hinaus ist in der Praxis mit diskreten und regellosen Gleislageabweichungen auch in Bögen zu rechnen, was wiederum die Berührgeometrie Rad / Schiene im negativen Sinne wesentlich beeinflusst. Hierdurch wird erst der eigentliche Nachteil der kurvenradialen Einstellung von selbststeuernden Radsätzen deutlich, weil die gegenseitige Selbststeuerung systembedingt in hohem Masse vom Gleiszustand und der daraus resultierenden Rad / Schiene - Berührgeometrie abhängig ist.As is known, a certain difference in the rolling radii is required for wear-free kinematic rolling of a wheel set in the track curve, depending on the distance between its wheel contact points. In addition to a sufficient coefficient of adhesion, the freedom of rotation of the wheel set and the wheel difference are the prerequisites that must be met for a radial adjustment of the wheel sets in the curve. Recent research has also shown that self-steering Wheelsets under the assumption of a wear-adapted wheel profile, a certain rail profile must be assumed, when paired the roll radius difference required as a function of the arc radius can be built up. This ideal rail profile is hardly available due to different wear conditions on a route network or cannot be maintained economically. In addition, discrete and irregular track position deviations can also be expected in arches, which in turn has a significant negative impact on the wheel / rail contact geometry. This only makes the actual disadvantage of the self-steering wheel sets, which is dependent on the radial curve, clear, because the mutual self-control depends to a large extent on the track condition and the resulting wheel / rail contact geometry.
Vor diesem Hintergrund zeigt die zuvorgenannte EP - PS 0 389 582 in einer weiteren Ausführungsform ein Drehgestell, bei dem die Radsätze zur kastenseitigen Zwangssteuerung durch eine vertikal angeordnete Zwangssteuereinrichtung untereinander und über einen in Bezug auf den Drehgestellrahmen ausseniiegenden Anlenkpunkt mit dem Wagenkasten verbunden sind.Against this background, the aforementioned EP-PS 0 389 582 shows in a further embodiment a bogie in which the wheelsets for the box-side forced control are connected to one another by a vertically arranged positive control device and via a pivot point which is external to the bogie frame.
Hierdurch wird die Radsatzsteuerung vom Verschleisszustand der Schiene unabhängig und der als Folge der Spurführungskräfte auftretende Verschleiss an Spurkränzen und Schienenflanken ist gegenüber einer Selbststeuerung stark vermindert. Allerdings sind die Ausdrehwinkel der gummielastischen Lager in den Gelenkpunkten in der Regel relativ gross, was langfristig zu Ueberbeanspruchungen führen kann und eine reduzierte Dauerhaltbarkeit der Lager zur Folge hat. Daher schlägt die EP - PS 0 263 283 eine Zwangssteuereinrichtung vor, bei welcher die Radsätze zur kastenseitigen Zwangssteuerung durch eine horizontal angeordnete Zwangssteuereinrichtung untereinander und über einen in Bezug auf den Drehgestell¬ rahmen inneniiegenden Anlenkpunkt mit dem Wagenkasten verbunden sind.As a result, the wheelset control is independent of the wear condition of the rail and the wear on the flanges and rail flanks as a result of the guidance forces is greatly reduced compared to self-control. However, the angle of rotation of the rubber-elastic bearings in the hinge points is usually relatively large, which can lead to excessive stress in the long term and result in reduced durability of the bearings. EP-PS 0 263 283 therefore proposes a positive control device in which the wheel sets for positive control on the box side are connected to the car body by a horizontally arranged positive control device and via an articulation point on the inside with respect to the bogie frame.
Hierdurch werden der Rad / Schiene - Verschleiss und die Ausdrehwinkel in den Gelenkpunkten minimiert. Nachteilig zeigt sich einzig der innenliegende Anlenkpunkt, der in die andere Drehgestellseite hineinragt und zu konstruktiven Restriktionen führt, indem so der Einbauraum für Fahrmotoren und andere Aggregate verbaut wird.This minimizes wheel / rail wear and the turning angle at the articulation points. The only disadvantage is the internal articulation point, which protrudes into the other side of the bogie and leads to design restrictions by installing the installation space for traction motors and other units.
Hier setzt die Erfindung ein, deren Aufgabe darin besteht, ein Fahrwerk mit einem Lenkmechanismus gemäss dem Gattungsbegriff so weiterzubilden,This is where the invention comes in, the object of which is to further develop a chassis with a steering mechanism according to the generic term,
- dass die Radsätze unabhängig vom Verschleisszustand der Schienen kurvenradial gesteuert werden- That the wheel sets are controlled radially regardless of the wear of the rails
- dass die Ausdrehwinkel der gummielastischen Lager in den Gelenkpunkten möglichst klein bleiben- That the turning angle of the rubber-elastic bearings in the articulation points remain as small as possible
- dass die Anlenkung möglichst raumsparend erfolgt und Einschränkungen bezüglich des Einbauraums für Fahrmotoren und andere Aggregate vermeidet- That the articulation takes place as space-saving as possible and avoids restrictions regarding the installation space for traction motors and other units
- dass die Anlenkung eine gute Entkoppelung aufweist und eine Verschlechterung der Vertikaldynamik vermeidet • Diese Aufgabe wird erfindungsgemass durch die kennzeichnenden Merkmale der nebengeordneten Patentansprüche gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.- that the articulation has good decoupling and prevents deterioration of the vertical dynamics • This object is achieved according to the invention by the characterizing features of the independent claims. Advantageous further developments can be found in the subclaims.
Demnach wird für ein Fahrwerk der eingangs erwähnten Art erfindungsgem ss ein Lenkmechanismus vorgeschlagen, bei dem die Anlenkung am Wagenkasten in Bezug auf den Fahrwerkrahmen innenliegend erfolgt. Dabei sind die Radsätze zunächst in bekannter Weise durch je eine, im wesentlichen in einer vertikalen Ebene aussen am Fahrwerkrahmen angeordneten Steuereinrichtung untereinander verbunden, die im Fahrwerkrahmen gelagert ist und in Bezug auf diesen in einer, zur Steuereinnchtung parallel versetzten, zweiten vertikalen Ebene eine innenliegende Anlenkung aufweist, die mit dem Wagenkasten in einer Wirkverbiπdung steht.Accordingly, a steering mechanism according to the invention is proposed for a chassis of the type mentioned at the outset, in which the articulation on the car body takes place on the inside with respect to the chassis frame. The wheel sets are initially connected to each other in a known manner by a control device, which is arranged on the outside of the undercarriage frame, essentially in a vertical plane, which is mounted in the undercarriage frame and, in relation to the latter, in an internal articulation in a second vertical plane which is offset parallel to the control device has, which is in an active connection with the car body.
Der so entstehende Lenkmechanismus überträgt durch die erfindungsgemässe Anlenkung die bei Kurvenfahrt zwischen dem Wagenkasten und einem Fahrwerk in einer horizontalen Ebene stattfindende gleichsinnige Ausdrehbewegung beider Anlenkpunkte und setzt diese über die gemeinsame Lagerung von Anlenkung und Steuereinrichtung in gegenläufige Bewegungen der Steuereinrichtungen beider Fahrwerkseiten um.The steering mechanism created in this way transmits through the articulation according to the invention the turning movement of both articulation points in the same plane when cornering between the car body and a chassis and converts them into opposite movements of the control devices on both chassis sides via the joint mounting of the articulation and control device.
Durch diese konstruktive Ausführung wird erreicht, dass die Radsätze unabhängig vom Verschleiszustand der Schienen kurvenradial gesteuert werden und die Ausdrehwinkel der gummielastischen Lager, insbesondere in den Gelenkpunkten der Anlenkung möglichst klein bleiben, wobei die Anlenkung zudem raumsparend und ohne Einschränkungen für den Einbauraum anderer Aggregate gestaltet ist. Auf die im Betrieb ständig in den Richtungen vertikal und honzontal quer auftretenden Federwege des Wagenkastens reagiert die Steuereinrichtung durch die gezeigte Anlenkung unempfindlich, so dass sie hierdurch nicht ungewollt in Tätigkeit gesetzt wird. Ausserdem vermeidet die konstruktive Anordnung der Anlenkung eine Verschlechterung der Vertikaldynamik sowie Anregungen des Wagenkastens.This constructive design ensures that the wheel sets are controlled in a curve-radial manner regardless of the wear condition of the rails and that the angle of rotation of the rubber-elastic bearings, especially in the articulation points of the linkage, remains as small as possible, the linkage also being space-saving and without restrictions for the installation space of other units . The control device reacts insensitively to the spring travel of the car body, which occurs constantly in the vertical and horizontal directions during operation, by means of the articulation shown, so that it is not inadvertently activated as a result. In addition, the constructive arrangement of the articulation avoids a deterioration in the vertical dynamics and excitations of the car body.
Um den Effekt einer guten Entkoppelung besonders wirksam zu gestalten, ist nach einem weiteren Merkmal der Erfindung vorgesehen, den gezeigten Lenkmechanismus mit einer an sich bekannten mechanischen Entkoppelungsvorrichtung zu kombinieren. Der sich hieraus ergebende Synergismus dient dazu, die Lenkfunktion von der Längsbewegung zu entkoppeln, so dass der Lenkmechanismus hiervon vollkommen unbeeinflusst bleibt.In order to make the effect of a good decoupling particularly effective, it is provided according to a further feature of the invention to combine the steering mechanism shown with a mechanical decoupling device known per se. The resulting synergism serves to decouple the steering function from the longitudinal movement, so that the steering mechanism remains completely unaffected.
Nach einem weiteren Merkmal der Erfindung ist schliessiich vorgesehen, den erfindungsgemässen Lenkmechanismus mit mindestens einer Tilgereinπchtung zu kombinieren, um die Bewegungen aus dem Sinuslauf der Radsatze wirkungsvoll zu dämpfen. Hierdurch bleiben die dynamischen Drehbewegungen, welche die Radsätze insbesondere bei schneller Geradeausfahrt innerhalb des Spurspiels ausüben, auf die Steuereinnchtung des Lenkmechanismus ohne Einfluss.According to a further feature of the invention, provision is finally made for the steering mechanism according to the invention to be combined with at least one damper device in order to effectively dampen the movements from the sinusoidal motion of the wheel sets. As a result, the dynamic rotary movements which the wheel sets exercise, particularly when driving straight ahead within the track play, have no influence on the steering mechanism of the steering mechanism.
Die Kombination von Lenkmechanismus mit Entkoppelungsvorrichtung und / oder Tilgereinrichtung unterstützt damit in vorteilhafter Weise die Schaffung eines Fahrwerks mit kurvenradial gesteuerten Radsätzen. Die Erfindung wird anschhessend anhand einer Zeichnung beispielsweise erläutert, sowie deren Wirkung und Funktionsweise beschnebenThe combination of steering mechanism with decoupling device and / or damper device thus advantageously supports the creation of a chassis with radially controlled wheel sets. The invention is subsequently explained, for example, with reference to a drawing, and its effect and mode of operation are described

Die beschriebenen Möglichkeiten der Anordnung der Anlenkung (21, 21') dienen schliesslich dazu, die Entkoppelung in jedem Fall optimal zu gestalten und eine Verschlechterung der Vertikaldynamik sowie Anregungen des Wagenkastens (4) zu vermeiden.In addition, the articulation (21, 21 ") reacts insensitively to the spring travel of the car body (4) which occurs constantly in the vertical and horizontal directions during operation due to the articulation shown, so that the control device (11, 11 ') thereby does not operate unintentionally The described possibilities for arranging the articulation (21, 21 ') ultimately serve to optimally design the decoupling in each case and to avoid a deterioration in the vertical dynamics and suggestions of the car body (4).
Bei Kurvenfahrt wird die zwischen Wagenkasten (4) und Fahrwerk (1 ) stattfindende Ausdrehbewegung genutzt und die in einer horizontalen Ebene gleichsinnige Drehbewegung der beiden Anlenkpunkte (24, 24') in eine gegensinnige Drehbewegung in vertikaler Ebene auf die Steuerhebel (22, 22') der Anlenkung (21 , 21') übertragen. Durch die verdrehfeste Anordnung von Anlenkung (21, 21') und Steuereinrichtung (11 , 11') auf der gemeinsamen Drehwelle (9, 9') üben dabei die Steuereinrichtungen (11 , 11') gegenläufige Bewegungen aus. Dank ihrer z-förmigen Ausbildung wird so beispielsweise die Steuereinrichtung (11 ) der einen Fahrwerkseite gestreckt und gleichzeitig die Steuereinrichtung (11') der anderen Fahrwerkseite verkürzt. Somit werden die Radsätze (5, 5') einzig durch den erfindungsgemässen Lenkmechanismus (2, 2') und unabhängig vom Gleiszustand kurvenradial gesteuert. Figur 2 zeigt als weiteres bevorzugtes Ausfuhrungsbeispiel die Kombination eines erfindungsgemässen Lenkmechanismus (2, 2') mit einer mechanischen Entkoppelungsvorπchtung (31) und / oder mit einer zwischen der Steuereinrichtung (11 , 11') und dem Fahrwerkrahmen (4) angeordneten Tilgereinπchtung (39)When cornering, the unscrewing movement taking place between the body (4) and the chassis (1) is used and the rotational movement of the two articulation points (24, 24 ') in the same horizontal direction in a counter-rotating movement in the vertical plane on the control levers (22, 22') the linkage (21, 21 ') transmitted. Due to the torsion-proof arrangement of the linkage (21, 21 ') and control device (11, 11') on the common rotary shaft (9, 9 '), the control devices (11, 11') perform opposite movements. Thanks to its z-shaped design, the control device (11) on one chassis side is stretched, for example, and at the same time the control device (11 ') on the other chassis side is shortened. Thus, the wheel sets (5, 5 ') are controlled solely by the steering mechanism (2, 2') according to the invention and independently of the curve, regardless of the track state. FIG. 2 shows, as a further preferred exemplary embodiment, the combination of a steering mechanism (2, 2 ') according to the invention with a mechanical decoupling device (31) and / or with a damper device (39) arranged between the control device (11, 11') and the chassis frame (4).
Hierbei sind die Steuerstangen (23, 23') der Anlenkung (21 , 21') über die Gelenkpunkte (24, 24') mit den äusseren Hebeln (35, 35') einer wagenkastenseitig angebrachten Entkoppelungsvomchtung (31) verbunden. Diese besteht aus einer in zwei Drehlagem (33, 33') am Wagenkasten (4) drehbar gelagerten Verbtndungsweile (34), deren innerer verdrehfester Hebel (36) über die Verbindungsstange (38) in den Gelenkpunkten (37) mit dem Fahrwerkrahmen (3) verbunden istThe control rods (23, 23 ') of the linkage (21, 21') are connected via the articulation points (24, 24 ') to the outer levers (35, 35') of a decoupling device (31) on the car body side. This consists of a connection shaft (34) which is rotatably mounted on the body (4) in two pivot positions (33, 33 '), the inner torsion-proof lever (36) of which, via the connecting rod (38) in the articulation points (37) with the chassis frame (3) connected is
Der sich aus der Kombination von Lenkmechanism us (2 , 2') und Entkoppelungsvorπchtung (31) ergebende Synergismus dient dazu, die Lenkfunktion von der Längsbewegung zu entkoppeln, so dass der Lenkmechanismus (2, 2') hiervon vollkommen unbeeinflusst bleibtThe synergism resulting from the combination of steering mechanism (2, 2 ') and decoupling device (31) serves to decouple the steering function from the longitudinal movement, so that the steering mechanism (2, 2') remains completely unaffected by this
Nach einem weiteren Merkmal ist vorgesehen, einen erfindungsgemässen Lenkmechanismus (2, 2') mit mindestens einer zusätzlichen Tilgereinπchtung (39) auszustatten. Die Tilgereinπchtung (39) kann in Form mindestens eines Dämpfers, der vorzugsweise eine trockene Reibungskennlinie aufweist, zwischen einer Steuereinrichtung (11, 11') und dem Fahrwerkrahmen (3) angeordnet sein.According to a further feature, it is provided that a steering mechanism (2, 2 ') according to the invention is equipped with at least one additional damper device (39). The damper device (39) can be arranged in the form of at least one damper, which preferably has a dry friction characteristic, between a control device (11, 11 ') and the chassis frame (3).
Hierdurch werden die die Bewegungen aus dem Sinuslauf der Radsatze (5, 5'), welche diese insbesondere bei schneller Geradeausfahrt innerhalb des Spurspiels ausüben, wirkungsvoll gedämpft und bleiben auf die Steuereinrichtung (11 , 11') des erfindungsgemässen Lenkmechanismus (2, 2') ohne Einfluss.In this way, the movements resulting from the sinusoidal movement of the wheel sets (5, 5 '), which are particularly evident when driving straight ahead within the track play exercise, effectively damped and remain without influence on the control device (11, 11 ') of the steering mechanism (2, 2') according to the invention.
Die Kombination des erfindungsgemässen Lenkmechanismus (2, 2') mit einer Entkoppelungsvorrichtung (31) und / oder Tilgereinrichtung (39) unterstützt damit in vorteilhafter Weise die Schaffung eines Fahrwerks (1), dessen Radsätze (5, 5') einzig durch den Lenkmechanismus (2, 2") und unabhängig vom Verschleisszustand der Schienen kurvenradial gesteuert werden.The combination of the steering mechanism (2, 2 ') according to the invention with a decoupling device (31) and / or damper device (39) thus advantageously supports the creation of a chassis (1) whose wheelsets (5, 5') are provided solely by the steering mechanism ( 2, 2 ") and independently of the wear condition of the rails.
Im Sinne der Erfindung, je eine Steuereinrichtung (11 , 11') im wesentlichen in einer ersten vertikalen Ebene aussen am Fahrwerkrahmen (3) anzuordnen und diese mit einer, in Bezug auf den Fahrwerkrahmen (3) in einer zweiten vertikalen Ebene innen egenden Anlenkung (21 , 21') zu verbinden, ist es alternativ auch denkbar, die Drehwellen (9, 9') beider Fahrwerkseiten als einstückige Verbindungswelle auszuführen, auf welcher an deren äusseren Enden die Steuereinrichtungen (11 , 11') verdrehfest angeordnet sind.In the sense of the invention, one control device (11, 11 ') each is arranged essentially in a first vertical plane on the outside of the chassis frame (3) and this with an articulation (in relation to the chassis frame (3) in a second vertical plane) 21, 21 '), it is alternatively also conceivable to design the rotary shafts (9, 9') on both sides of the chassis as a one-piece connecting shaft, on the outer ends of which the control devices (11, 11 ') are arranged in a rotationally fixed manner.
In diesem Fall sind die in sich z-förmig aufgebauten Steuereinrichtungen (11 , 11') bezüglich der Anordnung ihrer Lenkerstangen (13, 14 und 13', 14') an den Lenkerhebeln (12, 12') beider Fahrwerkseiten geometrisch gegensinnig angeordnet. Die Anlenkung (21 ) erfolgt hierbei durch einen, ausserhalb der Mitte der einstückigen Verbindungswelle verdrehfest vorgesehenen, in seiner Ruhelage nahezu vertikal nach oben bzw. unten gerichteten zentralen Steuerhebel (22), der über eine fast horizontale Steuerstange (23) in einem Anlenkpunkt (24) mit dem Wagenkasten (4) verbunden ist, wobei in allen Gelenkpunkten gummielastische Lager (8) vorgesehen sind. In this case, the control devices (11, 11 '), which are constructed in a z-shape, are arranged geometrically in opposite directions with respect to the arrangement of their handlebar rods (13, 14 and 13', 14 ') on the handlebar levers (12, 12') on both chassis sides. The articulation (21) takes place by means of a central control lever (22), which is provided non-rotatably outside the center of the one-piece connecting shaft and, in its rest position, is directed almost vertically upwards or downwards ) is connected to the car body (4), rubber-elastic bearings (8) being provided in all articulation points.
