Abstract

The invention relates to an arrangement of anti-torsional elements located on running gears of vehicles with a tilting body, which travel on railroad tracks. The inventive anti-torsional element is fixed, by means of one fastening joint thereof, to the side of the running gear facing the center of the body relative to the longitudinal direction, while being fixed, by means of the other fastening joint thereof, to the side of the coach body facing the closest end of the coach body. The fastening joint that is fixed to the coach body is placed higher than or at the same level as the fastening joint which is fixed to the running gear at all times, even at the maximum inclination of the coach body such that a rotational movement of the running gear extends or compresses the anti-torsional element depending on the direction of the curve when the vehicle travels on a curve while a simultaneous inclination of the coach body towards the interior of the curve compresses or extends the anti-torsional element depending on the direction of the curve, resulting in the anti-torsional element not being extended or compressed, or if so, only to a minimal extent. The anti-torsional element is thus permanently operated at the optimal working point thereof.

Description

Ankopplunq von Schlinqerdämpfern an Neigetechnikfahrzeuge Coupling of shock absorbers to tilting technology vehicles
Die Erfindung betrifft Drehhemmungselemente an Laufwerken von Neigetechnikfahrzeugen auf Schienenwegen.The invention relates to anti-rotation elements on drives of tilting technology vehicles on railways.
Eisenbahnwagen bestehen i.R. aus einem Wagenkasten und zwei mit Radsätzen ausgerüsteten Laufwerken, die gelenkig mit dem Wagenkasten verbunden sind. An die gelenkige Lagerung der Laufwerke am Wagenkasten wird die For- derung nach einem hohen Fahrkomfort gestellt. Der Wagenkasten soll möglichst erschütterungsfrei bleiben und einen hohen Federungskomfort aufweisen. Zusätzlich muss vor allem bei hohen Geschwindigkeiten stabiles Laufverhalten der Laufwerke, d. h. keine Schlingerbewegungen, erzielt werden. Herkömmlicherweise werden dafür Drehhemmungselemente eingesetzt, welche einerseits am Wagenkasten und andererseits am Fahrwerkrahmen angreifen. Diese Dämpfungselemente bestehen in der Regel aus hydraulischen Schwingungsdämpfern, welche gelenkig an Konsolen der entsprechenden Angriffspunkten befestigt werden.Railway wagons usually exist. consisting of a car body and two drives equipped with wheelsets that are articulated to the car body. The articulated mounting of the drives on the car body calls for a high level of driving comfort. The body should remain as free from vibrations as possible and have a high level of suspension comfort. In addition, especially at high speeds, stable running behavior of the drives, i. H. no rolling movements can be achieved. Conventionally, anti-rotation elements are used for this purpose, which act on the one hand on the car body and on the other hand on the chassis frame. These damping elements usually consist of hydraulic vibration dampers, which are articulated to the brackets of the corresponding points of attack.
Auf bogenreichen Strecken werden Neigetechnikfahrzeuge eingesetzt, bei de- nen sich der Wagenhasten ähnlich Motorradfahrern in die Kurve neigt. Hierdurch wird im Inneren des Neigetechnikfahrzeugs eine teilweise Kompensation der durch die Bogenfahrt hervorgerufenen Fliehkraft und somit eine Erhöhung des Fahrkomforts für Reisende erreicht.Tilting technology vehicles are used on routes with a lot of arches, in which the car body leans into the curve like motorcyclists. As a result, a partial compensation of the centrifugal force caused by the bow travel and thus an increase in driving comfort for travelers is achieved in the interior of the tilting technology vehicle.
Das Drehhemmungselement eines Neigetechnikfahrzeuges wird nun bei einer Bogenfahrt zum einen durch die Drehung des Laufwerkes auf dem Kurvenbogen gelängt oder gestaucht sowie zum anderen durch die Neigung des Wagenkastens in den Bogen ebenfalls gelängt oder gestaucht.The anti-rotation element of a tilting technology vehicle is now elongated or compressed on the one hand by the rotation of the running gear on the curved curve and on the other hand also elongated or compressed by the inclination of the car body in the curve.
Gemäß dem Stand der Technik, insbesondere aus DE 41 18 366 C2, wird ein Drehhemmungselement derart zwischen Laufwerk und Wagenkasten ange- bracht, dass in einem Rechtsbogen das Drehhemmungselement z.B. gelängt sowie durch die Neigung des Wagenkastens zusätzlich gelängt wird. Das Drehhemmungselement muss somit eine große quasistatische Bewegung durchführen. Diese quasistatische Bewegung überlagert die eigentliche dynamische Bewegung des Drehhemmungselementes, die zu der Dämpfungswirkung führt. Dadurch erfährt das Fahrwerk im Bogeneinlauf ein zusätzliches nach Bogenau- ßen gerichtetes Moment, wodurch die Querkräfte am ohnehin stärker bean- spruchten bogenäußeren Rad des vorlaufenden Radsatzes weiter erhöht werden. Gleichzeitig erfährt der Wagenkasten ein Moment das gegen die Antriebe der Neigetechnik arbeitet.According to the prior art, in particular from DE 41 18 366 C2, an anti-rotation element is attached between the running gear and the body of the vehicle in such a way that the anti-rotation element is elongated in a right-hand curve, for example, and is additionally lengthened by the inclination of the body. The anti-rotation element must therefore perform a large quasi-static movement. This quasi-static movement superimposes the actual dynamic movement of the anti-rotation element, which leads to the damping effect. As a result, the undercarriage experiences an additional moment directed towards the outside of the curve, which means that the lateral forces are already subjected to greater stress. said outer wheel of the leading wheelset to be further increased. At the same time, the car body experiences a moment that works against the drives of the tilting technology.
Es ist somit Aufgabe der Erfindung, eine Ankopplung von Drehhemmungsele- menten anzugeben, bei der höhere Radkräfte und höhere innere Kräfte im Wagenkasten vermieden werden.It is therefore an object of the invention to provide a coupling of anti-rotation elements in which higher wheel forces and higher internal forces in the car body are avoided.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Hauptanspruches erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.This object is achieved in connection with the preamble of the main claim according to the invention by the features specified in claim 1.
Vorteil des erfindungsgemäßen Verfahrens ist, dass « bei einer Bogenfahrt eine Drehbewegung des Laufwerkes je nach Richtung des Bogens das Drehhemmungselement längt oder staucht undThe advantage of the method according to the invention is that, when traveling through a bend, a rotational movement of the drive, depending on the direction of the bend, elongates or compresses the rotation-inhibiting element and
• im Gegensatz dazu eine gleichzeitige Neigung des Wagenkastens zum Bo- geninneren hin das Drehhemmungselement je nach Richtung des Bogens staucht oder längt, so dass sich das Drehhemmungselement in der Summe nicht bzw. nur geringfügig längt oder staucht. Hierdurch wird das Drehhemmungselement stets in seinem optimalen Arbeitspunkt betrieben.• In contrast, a simultaneous inclination of the car body towards the inside of the sheet restricts or lengthens the anti-rotation element depending on the direction of the sheet, so that the total amount of the anti-rotation element does not lengthen or compresses only slightly. As a result, the anti-rotation element is always operated in its optimal working point.
Ansprüche 2 und 3 beinhalten vorteilhafte Ausführungsbeispiele der erfindungsgemäßen Lösung aus Anspruch 1.Claims 2 and 3 contain advantageous exemplary embodiments of the solution according to the invention from claim 1.
Die Erfindung wird nachstehend anhand einer Zeichnung mit 2 Figuren näher erläutert. Die Figuren zeigen inThe invention is explained below with reference to a drawing with 2 figures. The figures show in

Fig. 2a Rechtsbogen,2a right sheet,
Fig. 2b Linksbogen. Bei dem Neigetechnikfahrzeug nach dem Stand der Technik gemäß Fig. 2 wird das Drehhemmungselement 6 z.B. in einem Rechtsbogen (Fig. 2a) gelängt, da das Fahrwerk 3 im Uhrzeigersinn in Richtung 2 ausdrehen muss um dem Bogen zu folgen und gleichzeitig der Wagenkasten 1 in Richtung 9 nach Bogeninnen geneigt werden soll. Diese Längung erzeugt im Drehhemmungselement 7 innere Kräfte, die dazu führen, dass das Fahrwerk 2 nach Bogenaußen gedreht wird und die Neigung des Wagenkastens 1 behindert wird.Fig. 2b left bow. In the case of the tilting technology vehicle according to the prior art according to FIG. 2, the anti-rotation element 6 is elongated, for example, in a right-hand bend (FIG. 2a), since the undercarriage 3 has to turn clockwise in the direction 2 in order to follow the bend and at the same time the car body 1 in the direction 9 to be inclined towards the inside of the arch. This elongation generates internal forces in the anti-rotation element 7, which cause the undercarriage 2 to be turned towards the outside of the arch and the inclination of the car body 1 is impeded.
Bei dem Neigetechnikfahrzeug mit der erfindungsgemäßen Ankopplung des Drehhemmungselementes 7 gemäß Fig. 1 zieht die Bewegung des Wagenkas- tens 1 durch die Neigetechnik das Fahrwerk 3 in den Bogen in Position 2 hinein. Als Reaktion unterstützt die Bewegung des Fahrwerkes 2 in den Bogen die Neigebewegung des Wagenkastens 1.1, the movement of the car body 1 by the tilting technique pulls the undercarriage 3 into the bend in position 2. In response, the movement of the undercarriage 2 in the arch supports the tilting movement of the car body 1.
Die fahrwerkseitige Anbindung 5 des Drehhemmungselementes 6 muss dabei auch bei maximaler Neigung des Wagenkastens 1 niedriger oder höchstens gleich hoch liegen wie die wagenkastenseitige 4. Denn läge die fahrwerkseitige Anbindung 5 des Drehhemmungselementes 6 über der wagenkastenseitigen 4 ergäbe sich der gleiche nachteilhafte Effekt wie beim Stand der Technik. The chassis-side connection 5 of the anti-rotation element 6 must also be lower or at most the same height as the wagon body-side 4 even with the maximum inclination of the car body 1. Because if the chassis-side connection 5 of the anti-rotation element 6 were above the wagon-body side 4, the same disadvantageous effect would result as in the state of the art Technology.
