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 version for the axle guide, the bogie or vehicle frame itself via spring elements on the with longitudinal and transverse play supported axle bearing housings of the wheelset.

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 Lenkergestelle durch die Längsdämpfer mitbedämpf werden.Mit diesen Anordnungen können die relativen Drehbewegungen zwischen den Radsätzen zwar gedämpft werden, 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.
Nach US-A-4 561 360 ist eine symmetrische und minimale Dämpferanordnung für alle drei Dämpfungsebenen (vertikal, horizontal quer und horizontal längs) bekannt. Diese Vertikaldämpfung erfordert eine möglichst senkrechte Anordnung der Dämpfer. Hohe Fahrgeschwindigkeiten erfordern eine definierte Horizontaldämpfung. Der in dieser bekannten Anordnung vorgeschlagene Kompromiß ist nur für niedrige Fahrgeschwindigkeiten geeignet. 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 handlebar frames 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 complex 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.
According to US-A-4 561 360, a symmetrical and minimal damper arrangement for all three damping planes (vertical, horizontal transverse and horizontal longitudinal) is known. This vertical damping requires the dampers to be arranged as vertically as possible. High driving speeds require a defined horizontal damping. The compromise proposed in this known arrangement is only suitable for low driving speeds.

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 a drive for rail vehicles of the type mentioned at the beginning, the special design and arrangement of the Damping version for the axis guidance the damping improved, high driving speeds possible, ensures a safe curve of the vehicle while reducing the disadvantages of the aforementioned known designs. With the proposed Execution is intended to influence the damping behavior the drive are exercised with clearly defined damping sizes and with a minimized Number of components influencing 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 Fahrzeugsrahmens 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 vom dem Horizontalstoßdämpfer und dem Vertikalstoßdämpfer gleichzeitig bedämpft werden und in abgemindeter 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 Kraftwirkungslinie wird diese unterhalb der horizontalen Achsmitte geschnitten und bildet zu den Befestigungskonsolen definierte und einstellbare Winkel, so daß der Dämpfungsanteil des Vertikalstoßdämpfers variierbar ist. The object is achieved by the features of the claim solved, i.e. that vertical and Horizontal shock absorbers by their arrangement to each other and by their arrangement at attachment points of the The bogie or vehicle frame correspond to each other in such a way that when the horizontal shock absorber moves a rotational movement of the axle bearing housing is generated, which in turn by the vertical shock absorber is additionally damped, the longitudinal movements of the wheelset from the horizontal shock absorber and the Vertical shock absorbers can be damped and simultaneously in a diminished form this also applies to the transverse movements of the wheelset applies. The vertical shock absorber is in the damping characteristics of the horizontal shock absorber involved. By changing the attachment points of the horizontal shock absorber and thus by the The change in the line of force action becomes this cut below the horizontal axis and forms to the mounting brackets and defined adjustable angle so that the damping component of the Vertical shock absorber is variable.

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 zur Fahrzeuglängsrichtung und in einem zur Horizontalen geneigt zwischen Rahmen 7 des Drehgestelles bzw. Fahrzeuges und dem Achsgehäuse 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 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 Dämpfunf 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 zusätzliche Dämpfungswirkungen auch empirisch bestimmt werden können, d.h. daß durch Veränderung des Abstandes h über die Neigung des Winkels 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 Radsatzbewegung 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. On the frame 7 of the bogie or vehicle are at least one vertical shock absorber per axle bearing 3. The vertical shock absorber 3 is between Axle center 1 and axle coil spring center 2 approximately vertical and the horizontal shock absorber 8 is in an angle to the longitudinal direction of the vehicle and in one inclined to the horizontal between frame 7 of the bogie or vehicle and the axle housing 6 arranged. The horizontal shock absorber 8 is attached to the frame 7 at attachment point 4 and with his other End at articulation point 15 on one on the axle bearing housing 6 arranged mounting bracket 5. The mounting bracket 5 is arranged so that the pivot point 15 of the horizontal shock absorber 8 at a distance a to the vertical axis center 1 and a distance h to the horizontal axis center 13 is mounted. The Line of action 12 of the horizontal shock absorber 8 cuts the vertical axis center 1 in one Point that is at a distance c from the horizontal axis center 13 lies in the top view according to Fig Force line 12, the wheelset center line 10 and forms the distance b to the connecting line 11 between front and rear coil springs 14. This distance b can depend on the chosen one Articulation point 15 be greater or less than zero. The cheapest damping and thus maximum driving behavior is determined by the articulation point 15 reached, influencing the vertical shock absorber 3 through the horizontal shock absorber 8 and thus the additional damping effects also empirically can be determined, i.e. that through change of the distance h over the inclination of the angle of the Horizontal shock absorber 8 or about the change the distance h and / or the distance a the damping component of the vertical shock absorber 3 on the damping the horizontal wheelset movement adjustable is. By changing the distance b is the radial adjustment behavior of the wheel set 9 via the horizontal shock absorber 8 can be influenced. 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 in a reduced form for the wheelset transverse movements to. With this adjustability of the horizontal shock absorber 8 by fixing the mounting bracket 5 the longitudinal damping can be set in this way be that high speeds at the same time good cornering behavior can be achieved.
