Abstract

The chassis has a pair of wheel beams (7) extending parallel to the rails and coupled together via cross beams (20), each fitted with front and rear wheels at its ends. A cross member (4) is supported from the wheel beams via primary springs (5,6), with the rail vehicle carriage supported from the cross member via secondary springs (2,3). Coupling elements with transverse rigidity is provided between each of the wheel beams and the cross member, permitting vertical movement of the latter relative to the wheel beams.

Description

Die Erfindung betrifft ein Drehgestell eines Schienenfahrzeugs gemäß dem Patentanspruch 1.The invention relates to a bogie of a rail vehicle according to claim 1.

Ein Drehgestell dieser Art ist aus der DE-PS 705 934 bekannt, bei dem die Radbalken mittels senkrechter Zapfen und mittels Schwenklagern drehbar an einem Querträger abgestützt sind, wobei zwischen Querträger und den Radbalken Federn angeordnet sind. Die aus einer Tragstruktur zusammengesetzten Radbalken sind durch Querstangen gelenkig miteinander gekoppelt. Die Schwenklager und die Halterungs- und Führungsvorrichtungen, mit denen die Radbalken vertikal verschieblich am Querträger befestigt sind, sind verschleißanfällig und aufwendig in der Bauweise und Wartung, zudem sind verhältnismäßig große Massen als ungefederte Massen gegeben, so daß das bekannte Drehgestell insbesondere für den Einsatz im Hochgeschwindigkeitsbetrieb wenig geeignet ist.A bogie of this type is known from DE-PS 705 934, in which the wheel bars are rotatably supported on a cross member by means of vertical pins and by means of pivot bearings, springs being arranged between the cross member and the wheel bars. The wheel beams composed of a support structure are articulated to one another by cross rods. The pivot bearings and the holding and guiding devices with which the wheel beams are vertically displaceably fastened to the cross member are prone to wear and costly in construction and maintenance, and relatively large masses are given as unsprung masses, so that the known bogie is particularly suitable for use in High-speed operation is not very suitable.

Der Erfindung liegt die Aufgabe zugrunde, ein hochgeschwindigkeitsfähiges Drehgestell mit einfacher Bauweise und geringer Verschleißanfälligkeit bzw. geringem Wartungsbedarf zu schaffen.The invention has for its object to provide a high-speed bogie with a simple design and low susceptibility to wear or low maintenance.

Diese Aufgabe wird durch ein Drehgestell gemäß den Merkmalen des Patentanspruchs 1 gelöst, die abhängigen Ansprüche geben weitere Entwicklungen der Erfindung an.This object is achieved by a bogie according to the features of claim 1, the dependent claims indicate further developments of the invention.

Durch die fliegende Lagerung der Laufräder bei innenliegenden Radbalken ergibt sich eine schmale Bauweise des Drehgestells, wodurch zur Verbesserung der Aerodynamik eines Hochgeschwindigkeits-Reisezugwagens der Anbau tiefreichender Drehgestellschürzen ermöglicht wird.The floating mounting of the wheels on the inner wheel beams results in a narrow bogie construction, which enables the mounting of deep bogie aprons to improve the aerodynamics of a high-speed passenger car.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

Fig. 1
die schematische Seitenansicht eines Drehgestells mit einem Teilbereich des Wagenkastens und
Fig. 2
die Vorderansicht des Drehgestells nach Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. Show it:
Fig. 1
the schematic side view of a bogie with a portion of the car body and
Fig. 2
the front view of the bogie of FIG. 1st

Gemäß Fig. 1 und 2 ist ein Wagenkasten 1 über Sekundärfedern 2 und 3 auf einem Querträger 4 abgestützt, der wiederum über Primärfedern 5 und 6 auf zwei Radbalken 7 und 8 abgestützt ist. An den Radbalken 7 und 8 sind bei innenliegenden Radbalken Laufräder 9 und 10 in Achsen 11 und 12 fliegend gelagert.1 and 2, a car body 1 is supported by secondary springs 2 and 3 on a cross member 4, which in turn is supported by primary springs 5 and 6 on two wheel beams 7 and 8. Impellers 9 and 10 are axially supported in axles 11 and 12 on the wheel beams 7 and 8 in the case of internal wheel beams.

Auf den Radbalken 7 und 8 einerseits und am Querträger 4 andererseits sind in quersteif ausgebildeten Gelenkpunkten 13 und 14 Längsstangen 15 gelagert.On the wheel beams 7 and 8 on the one hand and on the cross member 4 on the other hand, longitudinal rods 15 are mounted in articulated points 13 and 14.

Auf der Unterseite der Radbalken 7 und 8 sind Gelenkpunkte 18 und 19 angeordnet, in denen eine Querstange 20 angelenkt ist.On the underside of the wheel beams 7 and 8, articulation points 18 and 19 are arranged, in which a crossbar 20 is articulated.

Die auf der Schienenlauffläche 21 laufenden Laufräder 9 und 10, die Achsen 11 und 12, die Radbalken 7 und 8 sowie die Querstange 20 bilden die ungefederten Massen des Drehgestells, auf denen sich der Querträger 4 über die Primärfedern 5 und 6 abstützt. Die zwischen dem Wagenkasten 1 und dem Querträger 4 angeordneten Sekundärfedern 2 und 3 dienen zur Erhöhung des Fahrkomforts. Das Drehgestell ist bis auf die Gelenkpunkte der Längsstangen 15 und der Querstange 19 frei von Gelenken und Drehlagern und erfordert somit in der Bauweise und in der Wartung nur geringen Aufwand. Das Drehgestell ist insgesamt, vor allem jedoch in den ungefederten Massen leicht und somit als Hochgeschwindigkeitsdrehgestell für Reisezugwagen besonders geeignet.The running on the rail tread 21 wheels 9 and 10, the axles 11 and 12, the wheel beams 7 and 8 and the crossbar 20 form the unsprung masses of the bogie on which the cross member 4 is supported via the primary springs 5 and 6. The arranged between the car body 1 and the cross member 4 secondary springs 2 and 3 serve to increase driving comfort. Except for the articulation points of the longitudinal rods 15 and the transverse rod 19, the bogie is free of joints and pivot bearings and therefore requires little effort in terms of construction and maintenance. The bogie is light overall, but especially in the unsprung masses and is therefore particularly suitable as a high-speed bogie for passenger coaches.

Die Längsstangen 15 und die Querstange 19 stellen sicher, daß die Radbalken 7 und 8 in allen Betriebszuständen exakt positioniert bleiben.The longitudinal rods 15 and the transverse rod 19 ensure that the wheel beams 7 and 8 remain exactly positioned in all operating states.

Die quersteife Lagerung der Längsstangen 15 auf dem Querträger 4 und auf den Radbalken 7 und 8 kann grundsätzlich auch durch eine technisch gleichwirkende Verbindung von Querträger und Radbalken durch quersteife Blattlenker (nicht dargestellt) ersetzt werden, die eine freie vertikale Bewegung von Querträger und Radbalken zueinander zulassen, in Querrichtung jedoch steif sind. Durch diese Anordnung können weitere verschleißanfällige bzw. wartungsintensive Gelenkpunkte eliminiert werden. Es verbleibt nach dieser Lösung als Gelenkverbindung nur noch die gelenkige Anordnung der Querstange 15, mit der sichergestellt ist, daß die Radbalken 7 und 8 nicht nach innen einknicken.The transversely rigid mounting of the longitudinal rods 15 on the cross member 4 and on the wheel beams 7 and 8 can in principle also be replaced by a technically equivalent connection of the cross member and wheel beam by transversely rigid leaf links (not shown), which permit free vertical movement of the cross member and wheel beam with respect to one another , but are stiff in the transverse direction. With this arrangement, further wear-prone or maintenance-intensive articulation points can be eliminated. All that remains after this solution as an articulated connection is the articulated arrangement of the cross bar 15, which ensures that the wheel beams 7 and 8 do not buckle inwards.
