Description

Die Erfindung betrifft eine Abstützvorrichtung zur seitlichen elastischen Abstützung des Wagenkastens eines Schienenfahrzeuges gegenüber dessen Laufwerk, insbesondere Drehgestell, umfassend ein festes Gleitstück mit ebener Gleitfläche und ein diesem gegenüberliegendes, als Blattfeder mit konvexer Gleitfläche ausebildetes federndes Gleitstück, das an seinem ersten Längsende um eine Achse parallel zur ebenen Gleitfläche schwenkbar und an seinem zweiten Längsende parallel zur ebenen Gleitfläche verschiebbar gelagert ist.The invention relates to a support device for the lateral elastic support of the body of a rail vehicle relative to its drive, in particular bogie, comprising a fixed slide with a flat slide surface and an opposite, designed as a leaf spring with a convex slide surface resilient slide, parallel at its first longitudinal end about an axis is pivotable to the flat sliding surface and is displaceably mounted parallel to the flat sliding surface at its second longitudinal end.

Es ist bekannt, bei zentrisch mittels einer Drehpfanne, Drehkranz, Führungszapfen oder ähnlich geführten Drehgestellen, elastische Abstützungen zwischen dem Wagenkasten und den Drehgestellrahmen anzuordnen, die ein Ausdrehen der Drehgestelle ermöglichen und die mittels zwischengeschalteten abgefederten Gleitstücken, Relativdrehbewegungen zwischen dem Wagenkasten und den Drehgestellen ermöglichen, so daß eine weitgehend gleichmäßige Belastung durch den Wagenkasten erfolgt und unerwünschte übermäßig große Druckentlastungen einzelner Räder vermieden wird. Die Anpreßkraft der federnden Gleitstücke und damit die Teilentlastung der Führungsmittel des Drehgestells kann durch entsprechende Vorspannung der federnden Gleitstücke verändert werden.It is known to arrange elastic supports between the car body and the bogie frame in the case of centrically by means of a rotating pan, slewing ring, guide pin or similarly guided bogies, which allow the bogies to be unscrewed and which enable relative rotary movements between the car body and the bogies by means of interposed sprung sliders, so that there is a largely uniform load on the car body and undesirable excessive pressure relief of individual wheels is avoided. The contact pressure of the resilient sliders and thus the partial relief of the guide means of the bogie can be changed by appropriate preloading of the resilient sliders.

Bei den bekannten elastischen Abstützungen ist in der Regel eine feste Gleitplatte vorgesehen, die sich auf eine abgefederte Gleitplatte abstützt. Die abgefederte Gleitplatte ist dabei bei den bekannten Ausführungen mit Federelementen versehen, die eine vertikale Einfederung dieser elastischen Gleitplatte in begrenztem Umfang ermöglichen. Durch die Anordnung eines Federelementes zur vertikalen Nachgiebigkeit eines Gleitstücks ist hier die Anordnung von zusätzlichen Führungen erforderlich, damit das Gleitstück bei den Relativbewegungen des Drehgestells zum Wagenkasten exakt geführt wird.In the known elastic supports, a fixed slide plate is generally provided, which is supported on a spring-loaded slide plate. The spring-loaded sliding plate is provided with spring elements in the known designs, which allow vertical deflection of this elastic sliding plate to a limited extent. Due to the arrangement of a spring element for the vertical flexibility of a slider, the arrangement of additional guides is required here so that the slider is guided exactly when the bogie moves relative to the body.

Es ist ferner durch die US - A -1 958 188 eine Vorrichtung bekannt, die einander gegenüberliegende feste und federnde Gleitstücke umfaßt und zur seitlichen elastischen Abstützung des Wagenkastens von Schienenfahrzeugen gegenüber dessen Laufwerk dient. Das federnde Gleitstück ist mit konvexer Gleitfläche ausgebildet und besteht aus einer lediglich an ihren Längsenden abgestützten Blattfeder, die längsspielfrei und an einem ihrer Längsenden gelenkig gelagert ist.Furthermore, a device is known from US Pat. No. 1,958,188 which comprises fixed and resilient sliding pieces lying opposite one another and is used for the lateral elastic support of the car body of rail vehicles with respect to its running gear. The resilient slider is designed with a convex sliding surface and consists of a leaf spring supported only on its longitudinal ends, which is free of longitudinal play and is articulated on one of its longitudinal ends.

Die bekannten Anordnungen von elastischen Abstützungen sind in der Regel aufwendig oder bereiten beim Aufsetzen des Wagenkastens auf die Drehgestelle Schwierigkeiten.The known arrangements of elastic supports are usually complex or cause difficulties when placing the car body on the bogies.

Ein weiterer Nachteil der bekannten Ausführungen besteht darin, daß die federnden Gleitstücke auch in belastetem Zustand mit horizontalem Längsspiel versehen sind. Hierdurch fehlt bei Geradeausfahrt der gewünschte Drehhemmungseffekt der seitlichen Gleitstücke, so daß die Drehgestelle bei höheren Geschwindigkeiten zum Schlingern neigen.Another disadvantage of the known designs is that the resilient sliders are provided with horizontal longitudinal play even when loaded. As a result, the desired anti-rotation effect of the lateral sliding pieces is missing when driving straight ahead, so that the bogies tend to roll at higher speeds.

Die Erfindung hat sich zur Aufgabe gestellt, bei einer seitlichen ealstischen Wagenkastenabstützung der eingangs genannten Art diese Nachteile zu vermeiden, eine gleichmäßige Belastung der Räder zu erwirken, wobei die Abstützung ohne kostenaufwendige Bauteile gebildet werden sollte, und eine direkt wirkende Drehhemmung zwischen Wagenkasten und Drehgestell zu erzielen.The object of the invention is to avoid these disadvantages in the case of a lateral, rigid body support of the type mentioned at the outset, to achieve a uniform load on the wheels, the support being formed without costly components, and to have a direct-acting rotation inhibition between the body and the bogie achieve.

Diese Aufgabe der Erfindung wird dadurch gelöst, daß die gelenkige Lagerung des ersten Länsendes das federnde Gleitstück gegen Verschiebung in beiden Längsrichtungen sichert und daß das zweite Längsende parallel zur ebenen Gleitfläche nur durch Reibkräfte belastet ist. Durch diese Anordnung wird auf vorteilhafte Weise das federnde Gleitstück lediglich aus einer Blattfeder gebildet, die mit ihrer dem festen Gleitstück zugewandten Seite auch die Gleitfläche zur Auflage des festen Gleitstücks. bildet. Kostenaufwendige Bauteile werden somit vermieden. Die längsspielfreie Lagerung des federnden Gleitstücks ist mit einfachen Mitteln möglich.This object of the invention is achieved in that the articulated mounting of the first longitudinal end secures the resilient sliding piece against displacement in both longitudinal directions and that the second longitudinal end is loaded only by frictional forces parallel to the flat sliding surface. With this arrangement, the resilient slider is advantageously formed only from a leaf spring, the side facing the fixed slider also the sliding surface for supporting the fixed slider. forms. Costly components are thus avoided. The longitudinal play-free mounting of the resilient slider is possible with simple means.

Das federnde Gleitstück (Blattfeder) ist mite einer von etwa seiner Längenmitte nach beiden Auflagern hin sich parobolisch verringernden Querschnittshöhe ausgebildet. Durch die parabolische Ausbildung des Blattdickenverlaufs des elastischen Gleitstücks ist bei gegebener Baulänge eine maximale Elastizität des federnden Gleitstücks gegeben. Eine weiterer Vorteil der parabolischen Ausbildung des Federblattes des elastischen Gleitstücks besteht darin, daß die Blattfeder vorgesetzt werden kann und damit eine höhere Beanspruchung bei gleicher Materialqualität erfolgen kann.The resilient slider (leaf spring) is formed with a cross-sectionally parobolically decreasing cross-sectional height from about its length center toward both supports. Due to the parabolic design of the sheet thickness profile of the elastic slide, a maximum elasticity of the elastic slide is given for a given overall length. Another advantage of the parabolic design of the spring leaf of the elastic slider is that the leaf spring can be placed in front and thus a higher load can be made with the same material quality.

Das federnde Gleitstück (Blattfeder) ist an seinem gelenkig gelagerten Ende ein Lagerauge bildend aufgerollt. Durch diese Ausbildung der Blattfeder wird auf vorteilhafte Weise ein einfaches Bauelement erzielt und die Anordnung von zusätzlichen Lagerelementen vermieden.The resilient slider (leaf spring) is rolled up at its articulated end to form a bearing eye. This configuration of the leaf spring advantageously achieves a simple component and avoids the arrangement of additional bearing elements.

Zweckmäßig ist das Lagerauge des federnden Gleitstücks (Blattfeder) durch Abrollen der Blattfeder nach unten gebildet. Durch die Lagerung des federnden Gleitstücks in einem horizontalen Lagerauge mittels eines Bolzens wird selbst bei Spiel im Lagerauge eine absolut längsspielfreie Lagerung des federnden Gleitstücks erzielt. Im Zusammenhang mit der ständig wirksamen Vorspannkraft und der dadurch erzeugten Flächenpressung des federnden auf dem festen Gleitstück wird schon bei kleinsten Drehbewegungen des Drehgestells gegenüber dem Wagenkasten ein definiertes Moment ohne jedlichen Freigang erzeugt.The bearing eye of the resilient slider (leaf spring) is expediently formed by rolling the leaf spring downward. By mounting the resilient slider in a horizontal bearing eye by means of a bolt, an absolutely longitudinal play-free mounting of the resilient slider is achieved even with play in the bearing eye. In connection with the constantly effective pretensioning force and the resulting surface pressure of the resilient on the fixed slider, even with the smallest rotary movements of the bogie relative to the car body, a defined moment is lost generated all clearance.

Durch Wahl der Vorspannkraft und des Reibwertes der Gleitfläche kann eine optimale Drehhemmung erreicht werden, die die Instabilität des Drehgestells (Schlingern) bis zu hohen Geschwindigkeiten unterdrückt und gleichzeitig für den Bogenlauf die Führungskräfte am Spurkranz noch ausreichend klein hält.By selecting the preload force and the coefficient of friction of the sliding surface, an optimal rotation inhibition can be achieved, which suppresses the instability of the bogie (roll) up to high speeds and at the same time keeps the executives on the wheel flange sufficiently small for sheet travel.

Das freie Ende des federnden Gleitstücks liegt längsverschieblich und seitlich mit Spiel geführt auf einem Gleitstück auf. Durch diese in Längsrichtung freie Auflage des federnden Gleitstücks ist beim Einfedern des Gleitstücks eine zwängungsfreie Längsverschiebung dessen freien Endes ermöglicht.The free end of the resilient slider is longitudinally displaceable and laterally guided with play on a slider. This free support in the longitudinal direction of the resilient slider enables a compression-free longitudinal displacement of the free end of the slider when it is deflected.

In Längenmitte des federnden Gleitstücks ist mit Abstand unter diesem ein die Durchfederung begrenzender Endanschlag angeordnet.In the middle of the length of the resilient slider, an end stop limiting the deflection is arranged at a distance below it.

Einzelheiten der Erfindung sind in einem Ausführungsbeispiel in der Zeichnung erläutert.Details of the invention are explained in one embodiment in the drawing.

  • Fig. 1 shows the side view of an elastic support according to the invention z. T. on average,
  • FIG. 2 shows the top view of the elastic support according to FIG. 1.

Die elastische Abstützung gemäß der Erfindung besteht aus je einem festen und einem federnden Gleitstück. In der Zeichnung ist das feste Gleitstück nicht dargestellt. Dieses feste Gleitstück besteht, wie bei bekannten Ausführungen üblich, aus einer horizontal angeordneten auf ihrer Unterseite ebenen Gleitplatte, deren Gleitfläche eventuell mit einem zusätzlichen Belag mit hoher Verschleißfestigkeit oder niedrigem Reibungskoeffizienten ausgerüstet sein kann. Die Ausbildung dieses festen Gleitstücks ist jedoch nicht Gegenstand vorliegender Erfindung. Auf eine nähere Beschreibung wird somit verzichtet. Das federnde Gleitstück 1 ist aus einer Blattfeder gebildet, deren. nach oben gerichtete Gleitfläche im wesentlichen konvex ausgebildet ist. In seinem federnd wirksamen Bereich ist das federnde Gleitstück zu beiden Längsenden hin mit sich verringernder Querschnittshöhe parabolisch ausgebildet. An einem seiner Längsenden ist das federnde Gleitstück zu einem Lagerauge 2 aufgerollt, wobei dieses Lagerauge 2 durch Abrollen des federnden Gleitstücks 1 nach unten gebildet ist. Über dieses Lagerauge 2 ist das federnde Gleitstück 1 mittels eines quer zur Längsachse des Fahrzeugs angeordneten Bolzen 3 in Lagern 4 gelenkig gelagert. An seinem anderen freien Längsende ist das federnde Gleitstück 1 leicht aufgebogen und liegt mit seiner Unterseite längsverschieblich auf einem Gleitstück 5 auf. Das Gleitstück 5 ist mit seitlichen Führungen 5a versehen, die das federnde Gleitstück 1 mit Spiel seitlich führen. In etwa der Längsmitte des federnden Gleitstücks 1 ist mit Abstand unter diesem ein Endanschlag 6 vorgesehen, der die Durchfederung des federnden Gleitstücks 1 begrenzt.The elastic support according to the invention consists of a fixed and a resilient slider. The fixed slider is not shown in the drawing. This fixed slide consists, as is common in known designs, of a horizontally arranged slide plate on its underside, the slide surface of which may be equipped with an additional covering with high wear resistance or low coefficient of friction. However, the formation of this fixed slider is not the subject of the present invention. A detailed description is therefore omitted. The resilient slider 1 is formed from a leaf spring, the. upward sliding surface is substantially convex. In its resiliently effective area, the resilient slider is designed parabolically to both longitudinal ends with a decreasing cross-sectional height. At one of its longitudinal ends, the resilient slider is rolled up to form a bearing eye 2, this bearing eye 2 being formed by rolling the resilient slider 1 downward. About this bearing eye 2, the resilient slider 1 is articulated in bearings 4 by means of a bolt 3 arranged transversely to the longitudinal axis of the vehicle. At its other free longitudinal end, the resilient slider 1 is slightly bent and rests with its underside on a slider 5. The slider 5 is provided with lateral guides 5a which guide the resilient slider 1 laterally with play. Approximately the longitudinal center of the resilient slider 1, an end stop 6 is provided at a distance below it, which limits the deflection of the resilient slider 1.

Das federnde Gleitstück ist zweckmäßigerweise auf dem Drehgestell oder dem Laufwerk des Schienenfahrzeugs angeordnet, während des feste Gleitstück am Wagenkasten befestigt ist.The resilient slider is expediently arranged on the bogie or the running gear of the rail vehicle, while the fixed slider is attached to the car body.

Zur Verminderung der spezifischen Flächenpressung kann die Gleitfläche la des federnden Gleitstücks 1 in ihrer Längenmitte in einem kurzen Bereich eben ausgebildet sein, ohne daß dadurch die Federcharakteristik des federnden Gleitstücks nachteiligt beeinträchtigt wird.In order to reduce the specific surface pressure, the sliding surface 1 a of the resilient slider 1 can be made flat in the middle in a short area without the spring characteristic of the resilient slider being adversely affected thereby.
