Abstract

In the case of an axle bearing which can be adjusted in the direction of travel on a rail vehicle whose wheel sets are radially adjustable in bends, the roller bearing (2) rolls on a downwardly concave support face (7) with generated lines parallel to the axis during the adjustment movement of the axle bearing. In this process, the roller bearing (2) is guided in the axial direction by at least one wheel flange (4). The concave support face is attached to a spring carrier (6) which is guarded in axle holders (11, 12), the bogie frame (10) being mounted on the springs (8, 9) of the said spring carrier (6). This structure permits the adjustability of the wheel sets without a number of additional components subject to wear being required. <IMAGE>

Description

Achslagerung für SchienenfahrzeugeAxle bearings for rail vehicles

Die Erfindung betrifft ein in Fahrtrichtung einstellbares Achslager für Schienenfahrzeuge.The invention relates to an axle bearing that can be adjusted in the direction of travel for rail vehicles.

Bei Schienenfahrzeugen sollten sich die Radsätze in den Kurven radial einstellen können, um die Abnützung von Spurkränzen und Schienen zu vermindern. Dies ist vor allem wichtig bei Fahrzeugen mit grossen Achslasten, d.h. insbesondere bei Triebfahrzeugen und Güterwagen. Es sind mehrere Konstruktionen bekannt, welche die Einstellbarkeit der Radsätze erlauben.In the case of rail vehicles, the wheel sets should be radial in the curves can be adjusted to reduce wear on wheel flanges and rails. This is particularly important for vehicles with large axle loads, i.e. in particular for locomotives and freight wagons. Several constructions are known which allow the adjustability of the wheel sets.

Alle benötigen jedoch gegenüber der starren Achsführung eine Reihe zusätzlicher, der Abnützung unterworfener Bauteile, so dass sie insbesondere für die in grosser Zahl vorkommenden Güterwagen wegen der erhöhten Anschaffungs- und Unterhaltskosten nicht günstig sind.However, all of them require a number compared to the rigid axle guide additional components subject to wear, so that they are especially suitable for the freight wagons occurring in large numbers because of the increased purchase and Maintenance costs are not cheap.

Zweck der vorliegenden Erfindung ist, die Einstellbarkeit der Radsätze insbesondere von Drehgestell-Güterwagen in wirtschaftlicher Weise zu realisieren. Erfindungsgemäss wird dies dadurch erreicht, dass sich das Rollenlager der Achslagerung auf einer nach unter konkaven Auflagefläche mit achsparallelen Mantellinien abwälzt und dass es in Achsrichtung durch mindestens einen Spurkranz geführt wird.The purpose of the present invention is the adjustability of the wheel sets in particular to realize bogie freight wagons in an economical manner. According to the invention, this is achieved in that the roller bearing of the axle bearing on a concave support surface with axially parallel surface lines and that it is guided in the axial direction by at least one flange.

Im folgenden wird anhand der beiliegenden Zeichnung eine Ausführungsform der Erfindung erläutert. Es zeigen Fig. 1 den Querschnitt durch eine erfindungsgemässe Achslagerung in der Stellung auf geradem Geleise, Fig. 2 den Längsschnitt durch die Achslagerung, Fig. 3 ein Achslager in maximaler Kurvenstellung, Fig. 4 eine Variante mit sattelförmig auf dem Rollenlager angebrachter Abwälzfläche.An embodiment is described below with reference to the accompanying drawings the invention explained. 1 shows the cross section through an inventive Axle bearings in the position on a straight track, Fig. 2 shows the longitudinal section through the axle bearing, FIG. 3 an axle bearing in the maximum curve position, FIG. 4 a variant with a saddle-shaped rolling surface attached to the roller bearing.

Auf dem Achsschenkel 1 des Radsatzes ist in bekannter Weise das Rollenlager 2 angeordnet, das vom Achslagergehäuse 3 umschlossen wird. Die Aussenkontur des Achslagergehäuses ist zylindrisch oder schwach ballig und weist zwei Führungsspurkränze 4 und 5 auf. Das Achslagergehäuse stützt sich auf der nach unten konkaven Auflagefläche 7 mit achsparallelen Mantellinien des Federträgers 6 ab. Die Breite der Oeffnung im Federträger ist gleich dem Durchmesser des Achslagergehäuses plus dem doppelten Betrag des Längsspiels s um das sich das Achslager bei Kurvenfahrt verschieben kann und dadurch die radiale Einstellung des Radsatzes bewirkt, siehe Fig. 3. Die Krümmung der Auflagefläche erzeugt die erforderliche Rückstellkraft der Achse in die Mittellage als Horizontalkomponente der Achsschenkellast. Auf dem Federträger 6 ist in bekannter Weise über die Schraubenfedern 8 und 9 der Drehgestellrahmen 10 gelagert. Durch die an sich bekannten Achshalter 11 und 12 ist der Federträger am Drehgestellrahmen geführt.The roller bearing is on the steering knuckle 1 of the wheel set in a known manner 2 arranged, which is enclosed by the axle bearing housing 3. The outer contour of the Axle bearing housing is cylindrical or slightly convex and has two guide wheel flanges 4 and 5 on. The axle bearing housing is supported on the downwardly concave support surface 7 with axially parallel surface lines of the spring carrier 6. The width of the opening in the spring carrier is equal to the diameter of the axle box plus double that Amount of longitudinal play s by which the axle bearing can move when cornering and thereby causes the radial adjustment of the wheelset, see Fig. 3. The curvature the support surface generates the required restoring force of the axis in the central position as the horizontal component of the stub axle load. On the spring support 6 is known in Way via the coil springs 8 and 9 of the bogie frame 10 mounted. By the known axle holder 11 and 12 is the spring carrier on the bogie frame guided.

Fig. 4 stellt eine Variante dar, bei der die Abwälzfläche des Achslagers an einem sattelförmig auf das Rollenlager aufgesetzten Bauteil 13 angeordnet ist, wodurch sich eine Reduktion der Baumasse ergibt. Um ein Verschieben des Sattels im Betrieb zu verhindern, wird am Sattel ein Nocken 14 angebracht, der in eine entsprechende Vertiefung der Auflagefläche am Federträger eingreift.Fig. 4 shows a variant in which the rolling surface of the axle bearing on a saddle-shaped placed on the roller bearing Component 13 is arranged, which results in a reduction in the structural mass. To move To prevent the saddle in operation, a cam 14 is attached to the saddle, the engages in a corresponding recess in the support surface on the spring carrier.

Als weitere - zeichnerisch nicht dargestellte - Variante kann der Aussenring des Rollenlagers selbst mit Abwälzfläche und Spurkranz versehen werden.As a further - not graphically shown - variant can The outer ring of the roller bearing itself can be provided with a rolling surface and flange.
