Description

Die Erfindung betrifft einen Achshaltersteg zur Sicherung der Radsätze von Eisenbahnfahrzeugen an den äußeren Wangen der Drehgestellrahmen oder Wagenuntersätze. Die Achslager von Eisenbahn-Radsätzen sind in Aussparungen der äußeren Wangen der Drehgestellrahmen oder Wagenuntergestelle vertikal verschiebbar gelagert, um während des Betriebes ein Einfedern zu ermöglichen. Zur Sicherung der Radsätze nach unten beim Anheben des Wagens oder Drehgestelles sind die Aussparungen durch Achshalterstege verriegelt.The invention relates to an axle holder web for securing the wheel sets of railway vehicles on the outer cheeks of the bogie frame or car bases. The axle bearings of railroad wheel sets are vertically displaceably mounted in recesses in the outer cheeks of the bogie frames or undercarriages in order to allow compression during operation. To secure the wheel sets downwards when lifting the wagon or bogie, the recesses are locked by axle holder bars.

Da die Aussparungen für die Achslager eine erhebliche Schwächung der Drehgestellwangen bedeuten, sind die Achshalterstege und ihre Befestigung derart ausgeführt, daß sie große Zugkräfte aufnehmen können, d. h. auch im Normalbetrieb festigkeitssteigernd wirken.Since the recesses for the axle bearings mean a considerable weakening of the bogie cheeks, the axle holder webs and their attachment are designed such that they can absorb large tensile forces, i. H. also increase strength in normal operation.

Als Mittel zur Kraftübertragung von den Achshalterstegen auf die Wangen der Drehgestellrahmen finden Schraubverbindungen Anwendung (DE-PS 108 441, DE-PS 621 004). Bekannt sind ferner Verbindungen mittels Paßschrauben, Paßbuchsen mit Schrauben, Schulterstücke oder Abkantungen mit Schrauben und Verzahnungen mit Schrauben. Die Befestigung des Achshaltersteges muß hohen Anforderungen genügen. Sie muß eine starre, d. h. verformungsarme Übertragung großer Kräfte ermöglichen, und dabei möglichst verschleißfrei und betriebssicher und außerdem schnell und einfach lösbar sein. Die bekannten Achshalter und deren Befestigung entsprechen weitgehend den an sie gestellten Anforderungen, weisen jedoch den Nachteil auf, daß die Schraubverbindungen infolge Korrosion und Einwirkung von Schmutz schwer lösbar sind.Screw connections are used as a means of transmitting power from the axle holder webs to the cheeks of the bogie frame (DE-PS 108 441, DE-PS 621 004). Connections are also known by means of fitting screws, fitting bushes with screws, shoulder pieces or chamfers with screws and toothing with screws. The attachment of the axle holder web must meet high requirements. You must allow a rigid, ie low-deformation transmission of large forces, and be as wear-free and reliable as possible and also quick and easy to solve. The well-known Achshal ter and their attachment largely correspond to the requirements placed on them, but have the disadvantage that the screw connections are difficult to solve due to corrosion and exposure to dirt.

Es ist daher die Aufgabe der Erfindung, einen Achshalter so auszubilden, daß dieser die durch die Aussparung bedingte Schwächung der Drehgestellwange weitgehend ausgleicht und die Befestigung vereinfacht wird.It is therefore the object of the invention to design an axle holder in such a way that it largely compensates for the weakening of the bogie beam caused by the recess and the attachment is simplified.

Die Lösung der Aufgabe besteht darin, daß der Achshaltersteg parallele Profile und Druckstücke mit zur Senkrechten geneigten Druckflächen, die sich auf Vorsprün- gen der Drehgestellwange abstützen, aufweist und mittels auf der Drehgestellwange drehbar angeordneter Schaken unter Vorspannung von oben her gehalten ist.The object is that the Axle guard tie parallel profiles and plungers with inclined to the vertical pressure surfaces on Vorsprün - having supported gene of the sole-bar and is held forth by means of the sole-bar rotatably arranged Schaken under bias from above.

Infolge der zur Senkrechten geneigten Druckflächen an dem Achshaltersteg und den Vorsprüngen der Drehgestellwangen entsteht durch die Vorspannung der Befestigungsmittel eine keilförmige, kraftschlüssige feste Anlage mit großer Druckfläche und entsprechend kleiner Flächenpressung. Außerdem liegen der Achshaltersteg und die Drehgestellwange in einer Ebene, so daß keine zusätzlichen Biegemomente auftreten. Durch diese Maßnahmen wird die von der Aussparung reduzierte Steifheit der Wange erheblich verbessert. Die Zugkräfte im Achshaltersteg werden an den Druckflächen in zwei Komponenten aufgelöst, von denen nur die erheblich kleinere in vertikaler Richtung wirkt. Nur diese geringe Kraft ist von dem Befestigungsmittel des Achshaltersteges aufzunehmen. Die zur Befestigung des Achshaltersteges auf den Drehgestellwangen drehbar angeordneten Schaken sind robuste und unempfindliche Befestigungselemente, die es ermöglichen, den an seinen beiden Enden zum Aufbringen und Einrasten der Schaken entsprechend profilierten Achshaltersteg mit wenigen Hammerschlägen zu befestigen bzw. zu lösen. Die Sicherheit der schraubenlosen Verbindung des Achshaltersteges mit der Drehgestellwange ist dadurch gewährleistet, daß die Drehpunkte der Schaken der senkrechten Radachse näher liegen als ihre Anlagepunkte am Achshaltersteg. Da die Schaken aufgrund ihres Eigengewichtes die Tendenz haben, ihre funktionsgerechte Stellung beizubehalten, ist die Gefahr eines selbsttätigen Lösens infolge von Schwingungen oder Stößen beim Rangieren der Wagen vermindert. Eine Kontrolle der Achshaltersteg-Befestigung ist außerdem durch Inaugenscheinnahme leicht möglich.As a result of the pressure surfaces on the axle holder web and the projections of the bogie cheeks, which are inclined to the vertical, the pretensioning of the fastening means creates a wedge-shaped, non-positive fixed contact with a large pressure surface and a correspondingly small surface pressure. In addition, the axle holder web and the bogie cheek lie in one plane, so that no additional bending moments occur. These measures significantly improve the stiffness of the cheek, which is reduced by the recess. The tensile forces in the axle holder web are broken down into two components on the pressure surfaces, of which only the considerably smaller one acts in the vertical direction. Only this small force can be absorbed by the fastening means of the axle holder web. The shackles, which are rotatably arranged for fastening the axle holder web on the bogie cheeks, are robust and insensitive fastening elements, which make it possible to attach them at both ends and snap the shackles into place with a few hammer blows to fasten or loosen them accordingly. The security of the screwless connection of the axle holder web to the bogie cheek is ensured by the fact that the pivot points of the legs are closer to the vertical wheel axle than their contact points on the axle holder web. Since the shackles have a tendency to maintain their functional position due to their own weight, the risk of automatic release due to vibrations or shocks when maneuvering the wagons is reduced. It is also easy to inspect the axle holder web attachment by inspecting it.

Als zusätzliche Sicherheit kann vorgesehen werden, daß die Schaken gegen unbeabsichtigtes Lösen durch Sicherungselemente geschützt sind. Dazu sind in den Endabschnitten des Achshaltersteges Bohrungen vorgesehen, in die Splinte, Spannstifte oder dergl. eingebracht werden können. Gemäß einer Ausführungsform ist vorgesehen, daß die Schaken als federnde Elemente ausgebildet sind, die in Einrast-Profile am Achshaltersteg einrasten. Die Endabschnitte des Achshaltersteges sind so ausgebildet, daß die funktionsgerechte Einbaulage der Schaken ohne zusätzliche Sicherungslemente gewährleistet ist. Die aufwärts wirkende Zugkraft ist genau festgelegt und unabhängig vom Montagevorgang.As additional security it can be provided that the flaps are protected against unintentional loosening by securing elements. For this purpose, holes are provided in the end sections of the axle holder web, into which pins, dowel pins or the like can be introduced. According to one embodiment it is provided that the legs are designed as resilient elements which snap into snap-in profiles on the axle holder web. The end sections of the axle holder web are designed in such a way that the functionally correct installation position of the hooks is ensured without additional securing elements. The upward pulling force is precisely defined and independent of the assembly process.

Eine weitere Befestigungsart des Achshaltersteges besteht darin, daß zusätzlich zu als Federelemente ausgebildeten Schaken mit Langlöchern versehene Laschen vorhanden sind. Hierbei bewirken Spannschaken die Anpressung des Achshaltersteges an die Drehgestellwange. Die Laschen verhindern bei einem Bruch des Spannschakens ein Herabfallen des Achshaltersteges und der Spannschakenhälften.Another type of fastening of the axle holder web is that tabs provided with elongated holes are provided in addition to shackles designed as spring elements. In this case, tensioning hooks press the axle holder web against the bogie cheek. The tabs prevent the axle holder web and the clamping jaw halves from falling if the clamping jaw breaks.
