Abstract

Running gear for railway vehicles, which, by virtue of the particular arrangement of the damping components, improves damping, permits high travel speeds and ensures that bends can be travelled through safely. This object is achieved by means of the arrangement of the vertical and horizontal shock absorbers in such a way that as a result of the horizontal shock absorber force a rotational deflection of the axle bearing housing is produced, which rotational deflection is in turn additionally damped by the vertical shock absorber, the longitudinal movements of the wheel sets being simultaneously damped by the horizontal shock absorber and the vertical shock absorber and this also applying to a lesser degree to the transverse movements of the wheel sets. The vertical shock absorber is included in the damping characteristic of the horizontal shock absorber. By changing the attachment point of the horizontal shock absorber and thus by changing the points of intersection of the median lines of the shock absorbers and the median line of the axle bearing housing in the vertical and horizontal planes by means of an attachment bracket arranged in a defined manner it is possible to vary the damping ratio of the shock absorbers. The invention is suitable in particular for sets of running gear which are to be used for high speed transport. <IMAGE>

Description

Die Erfindung betrifft ein Laufwerk für Schienenfahrzeuge mit einer Dämpfungsausführung für die Achsführung, wobei der Drehgestell- oder Fahrzeugrahmen sich über Federelemente auf den mit Längs- und Querspiel geführten Achslagergehäusen des Radsatzes abstützt.The invention relates to a drive for rail vehicles with a damping design for the axle guide, wherein the bogie or vehicle frame is supported via spring elements on the axle bearing housings of the wheel set guided with longitudinal and transverse play.

Nach der DE 3904203 A1 sind Dämpfungsausführungen bekannt, bei denen zwischen den Radsatzlagern des einen Radsatzes und dem anderen Radsatz/oder den anderen Radsätzen Längsdämpfer und für die Dämpfung der Querbewegung entweder zusätzliche Querdämpfer angeordnet sind, oder die Querbewegungen über Lenkergestänge durch die Längsdämpfer mitbedämpft werden. Mit diesen Anordnungen können die relativen Drehbewegungen zwischen den Radsätzen zwar gedämpftwerden, sie haben aber den Nachteil, daß die Querdämpfer zusätzlich vorgesehen oder aufwendige Lenkergestänge mit hohen Verschleißerscheinungen angewendet werden. Darüber hinaus ist durch die deutsche Patentanmeldung Nr. P 42 42 685.5 eine in allen drei Ebenen wirkende Dämpfungseinrichtung für die Achsführung bekannt, bei der die Achse über federnd belastete reibungsgedämpfte Achslenker geführt ist. Diese Ausführung hat jedoch den Nachteil, daß sie in den beengten Einbauraum schwer montierbar ist.According to DE 3904203 A1 damping designs are known in which longitudinal dampers are arranged between the wheelset bearings of one wheel set and the other wheel set / or the other wheel sets and for the damping of the transverse movement either additional transverse dampers are arranged, or the transverse movements are also dampened by means of handlebar linkages by the longitudinal dampers. With these arrangements, the relative rotary movements between the wheel sets can be damped, but they have the disadvantage that the transverse damper is additionally provided or expensive linkage with high wear and tear is used. In addition, the German patent application No. P 42 42 685.5 discloses a damping device acting in all three levels for the axle guide, in which the axle is guided via spring-loaded, friction-damped axle links. However, this version has the disadvantage that it is difficult to install in the cramped installation space.

Aufgabe der Erfindung ist es, ein Laufwerk für Schienenfahrzeuge der eingangs genannten Art zu schaffen, das durch die besondere Gestaltung und Anordnung der Dämpfungsausführung für die Achsführung die Dämpfung verbessert, hohe Fahrgeschwindigkeiten ermöglicht, einen sicheren Kurvenverlauf des Fahrzeuges gewährleistet bei gleichzeitiger Verminderung der Nachteile der vorgenannten bekannten Ausführungen. Mit der vorgeschlagenen Ausführung soll Einfluß auf das Dämpfungsverhalten des Laufwerkes ausgeübt werden mit klar definierten Dämpfungsgrößen und bei einer minimierten Anzahl die Dämpfung beeinflussender Bauteile.The object of the invention is to provide a drive for rail vehicles of the type mentioned, which improves the damping by the special design and arrangement of the damping design for the axle guide, enables high driving speeds, ensures a safe curve of the vehicle while reducing the disadvantages of the aforementioned known versions. With the proposed design should influence the damping behavior of the drive with clearly defined damping variables and with a minimized number of components influencing the damping.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches gelöst, d.h., daß Vertikal- und Horizontalstoßdämpfer durch ihre Anordnung zueinander und durch ihre Anordnung an Befestigungspunkten des Drehgestell- oder Fahrzeugrahmens miteinander korrespondieren in der Art, daß bei Bewegungen des Horizontalstoßdämpfers eine Drehbewegung des Achslagergehäuses erzeugt wird, die wiederum durch den Vertikalstoßdämpfer zusätzlich bedämpft wird, wobei die Radsatzlängsbewegungen von dem Horizontalstoßdämpfer und dem Vertikalstoßdämpfer gleichzeitig bedämpft werden und in abgeminderter Form dies auch für die Radsatzquerbewegungen zutrifft. Der Vertikalstoßdämpfer wird in die Dämpfungscharakteristik des Horizontalstoßdämpfers einbezogen. Durch Veränderung der Befestigungspunkte des Horizontalstoßdämpfers und damit durch die Veränderung der Schnittpunkte der Dämpfermittellinien und der Mittellinie des Achslagergehäuses in senkrechter und horizontaler Ebene ist der Dämpfungsanteil des Vertikalstoßdämpfers variierbar.The object is achieved by the features of the claim, that is, that vertical and horizontal shock absorbers correspond by their arrangement to each other and by their arrangement at attachment points of the bogie or vehicle frame in such a way that when the horizontal shock absorber moves, a rotational movement of the axle bearing housing is generated , which in turn is additionally damped by the vertical shock absorber, the longitudinal movements of the wheelset being simultaneously dampened by the horizontal shock absorber and the vertical shock absorber and, in a reduced form, this also applies to the transverse movements of the wheelset. The vertical shock absorber is included in the damping characteristics of the horizontal shock absorber. By changing the attachment points of the horizontal shock absorber and thus by changing the intersection of the damper center lines and the center line of the axle bearing housing in the vertical and horizontal planes, the damping component of the vertical shock absorber can be varied.

Ein Ausführungsbeispiel der Erfindung soll anhand der Zeichnung näher erläutert werden. Die Zeichnung zeigt in:

Fig.1:

An embodiment of the invention will be explained in more detail with reference to the drawing. The drawing shows in:
Fig.1:
the view of the drive,
Fig. 2:
the diagram of a plan view, based on the center line of the wheelset and the line of action of the horizontal shock absorber.

An dem Rahmen 7 des Drehgestelles bzw. Fahrzeuges sind je Achslager mindestens ein Vertikalstoßdämpfer 3 vorgesehen. Der Vertikalstoßdämpfer 3 ist zwischen Achsmitte 1 und Achsschraubenfedermitte 2 annähernd senkrecht und der Horizontalstoßdämpfer 8 ist in einem Winkel α zur Fahrzeuglängsrichtung und in einem Winkel β zur Horizontalen geneigt zwischen Rahmen 7 des Drehgestells bzw. Fahrzeuges und dem Achslagergehäuse 6 angeordnet. Der Horizontalstoßdämpfer 8 wird an dem Rahmen 7 in dem Befestigungspunkt 4 und mit seinem anderen Ende am Anlenkpunkt 15 auf einer am Achslagergehäuse 6 angeordneten Befestigungskonsole 5 gehalten. Die Befestigungskonsole 5 ist so angeordnet, daß der Anlenkpunkt 15 des Horizontalstoßdämpfers 8 in einem Abstand a zur senkrechten Achsmitte 1 und in einem Abstand h zur horizontalen Achsmitte 13 gelagert ist. Die Kraftwirkungslinie 12 des Horizontalstoßdämpfers 8 schneidet dabei die vertikale Achsmitte 1 in einem Punkt, der im Abstand c zur horizontalen Achsmitte 13 liegt. In der Draufsicht nach Fig.2 schneidet die Kraftwirkungslinie 12 die Radsatzmittenlinie 10 und bildet dabei den Abstand b zur Verbindungslinie 11 zwischen vorderer und hinterer Schraubenfeder 14. Dieser Abstand b kann in Abhängigkeit von dem gewählten Anlenkpunkt 15 größer/kleiner gleich Null sein. Die günstigste Dämpfung und damit ein maximales Fahrverhalten wird durch die Festlegung des Anlenkpunktes 15 erreicht, wobei die Beeinflussung des Vertikalstoßdämpfers 3 durch den Horizontalstoßdämpfer 8 und damit die zusätzlichen Dämpfungswirkungen auch empirisch bestimmt werden können, d.h. daß durch Veränderung des Abstandes h über die Neigung des Winkels β des Horizontalstoßdämpfers 8 bzw. über die Veränderung des Abstandes h und/oder des Abstandes a der Dämpfungsanteil des Vertikalstoßdämpfers 3 an der Dämpfung der horizontalen Radsatzbewegungen einstellbar ist. Durch Veränderung des Abstandes b ist das Radialeinstellungsverhalten des Radsatzes 9 über den Horizontalstoßdämpfer 8 beeinflußbar. Diese gleichzeitige Bedämpfung der horizontalen Radsatzbewegungen durch den Horizontalstoßdämpfer 8 und Vertikalstoßdämpfer 3 durch Verstellung des Horizontalstoßdämpfers 8 trifft somit in abgeminderter Form auch für die Radsatzquerbewegungen zu. Mit dieser Einstellbarkeit des Horizontalstoßdämpfers 8 durch die Fixierung der Befestigungskonsole 5 kann die Längsdämpfung so eingestellt werden, daß hohe Geschwindigkeiten bei gleichzeitigem guten Kurvenverhalten erreicht werden.At least one vertical shock absorber 3 is provided on the frame 7 of the bogie or vehicle per axle bearing. The vertical shock absorber 3 is approximately vertical between the center 1 of the axle and the coil spring 2, and the horizontal shock absorber 8 is arranged at an angle α to the longitudinal direction of the vehicle and at an angle β to the horizontal between the frame 7 of the bogie or vehicle and the axle bearing housing 6. The horizontal shock absorber 8 is held on the frame 7 in the fastening point 4 and with its other end at the articulation point 15 on a fastening bracket 5 arranged on the axle bearing housing 6. The mounting bracket 5 is arranged so that the articulation point 15 of the horizontal shock absorber 8 is mounted at a distance a from the vertical axis center 1 and at a distance h from the horizontal axis center 13. The line of action 12 of the horizontal shock absorber 8 intersects the vertical axis center 1 at a point which is at a distance c from the horizontal axis center 13. In the plan view according to FIG. 2, the line of action 12 intersects the center line 10 of the wheelset and forms the distance b to the connecting line 11 between the front and rear coil springs 14. This distance b can be greater than or less than zero depending on the selected articulation point 15. The cheapest damping and thus maximum driving behavior is achieved by determining the articulation point 15, the influence of the vertical shock absorber 3 by the horizontal shock absorber 8 and thus the additional damping effects also being able to be determined empirically, ie by changing the distance h via the inclination of the angle β of the horizontal shock absorber 8 or, by changing the distance h and / or the distance a, the damping component of the vertical shock absorber 3 in the damping of the horizontal wheel set movements can be adjusted. By changing the distance b, the radial adjustment behavior of the wheel set 9 can be influenced via the horizontal shock absorber 8. This simultaneous damping of the horizontal wheel set movements by the horizontal shock absorber 8 and vertical shock absorber 3 by adjusting the horizontal shock absorber 8 thus also applies to the wheel set transverse movements in a reduced form. With this adjustability of the horizontal shock absorber 8 by fixing the mounting bracket 5, the longitudinal damping can be adjusted so that high speeds are achieved with good cornering behavior.
