Description
Gelenkwagenzug Die vorliegende Erfindung bezieht sich auf einen Gelenkwagenzug, welcher aus mindestens zwei Ele menten besteht und mindestens drei Drehgestelle auf weist.
Bei den bekannten Gelenkwagenzügen sind zwi schen den Elementen vollkommen gelenkige Verbin- dungen vorgesehen, bei welcher Anordnung die Last verteilung auf d=ie drei Drehgestelle selbsttätig er folgt. In der Praxis wird aber je nach Anordnung der Triebdrehgestelle eine ganz bestimmte Lastverteilung vorgeschrieben. Werden z. B. die beiden Enddreh- Bestelle angetrieben, so muss ein bestimmter Anteil des Totalzuggewichtes auf diese Drehgestelle wirken, da sonst die notwendige Adhäsion nicht gewähr leistet ist.
Man hat bereits vorgeschlagen, die Gelenke zwi schen den Wagenkasten so auszubilden, dass im Unter- gestell ein kugelförmiges Gelenk verwendet wird, wäh rend im Oberteil sich die Wagenkasten gegenseitig über horizontal gelagerte Federn abstützen. In die ser Weise wird ein bestimmter Anteil der Vertikallast auf die Enddrehgestelle verlagert. Diese Anordnung hat jedoch den Nachteil, dass sie kompliziert ist.
Fer ner ist eine solche Gelenkverbindung labil, so dass die einzelnen Wagenkasten gegeneinander unkontrol lierbare Schwingungen ausführen können. Zweck der Erfindung ist die Vermeidung der erwähnten Nach- teile.
Der erfindungsgemässe Gelenkwagenzug ist da durch gekennzeichnet, dass die Elemente unter sich in der vertikalen Längsebene starr verbunden sind, wobei das mittlere Drehgestell eine Federung mit flacherer Charakteristik als die Enddrehgestelle auf weist.
In dieser Weise wird erreicht, dass die Wagen kasten gegeneinander nur einen Freiheitsgradl der Bewegung besitzen, das heisst sie können sich nur beim Kurvenlauf gegeneinander um einen bestimmten Winkel verdrehen. Dabei wird die Lastverteilung auf die drei Drehgestelle beim Fahren auf horizontalem, geradem Geleise nur durch Federsteifigkeit der Drehgestellfederungen bestimmt.
Durch eine sehr weiche Federung des Mitteldrehgestelles gegenüber den Enddrehgestellen wird ein Teil der Vertikal- last über die Gelenke zwischen den einzelnen Wagen kasten auf die Enddrehgestelle übertragen.
Auf beiliegender Zeichnung sind zwei Ausfüh rungsbeispiele des Erfindungsgegenstandes dargestellt, und zwar zeigen Fig. l eine schematische Skizze einer ersten Aus führung und Fig. 2 eine zweite Ausführung eines Gelenkwagen- Zuges. Gemäss der in der Fig. 1 dargestellten Ausfüh rung weist der Gelenkwagenzug drei Glieder 1, 2 und 3 auf, die je einen Wagenkasten 4, 5 und 6 sowie zugehörige Drehgestelle 7, 8 und 9 besitzen.
Die Glieder 1, 2 und 3 sind untereinander durch Kupplungen 10 und 11 verbunden, welche in der ver- tikalen Längsebene starr wirken, so de die Wagen kosten gegeneinander nur :
einen Freiheitsgrad der Bewegung besitzen, das heisst sie können sich nur beim Kurvenlauf gegeneinander um einen bestimm- ten Winkel verdrehen. Gemäss der dargestellten Aus- führung ist sowohl im Bereiche des Daches als auch im Bereiche des Untergestelles je :eine Kupplung 10 bzw. 11 vorgesehen.
Beim Fahren auf horizontalem, geradem Geleise wird die Lastverteilung auf die drei Drehgestelle durch die Federsteifigkeit der Drehgestellfederungen be stimmt. Durch eine weichere Federung des. Mittel- drehgestelles. gegenüber den Enddrehgestellen wird ,ein Teil der Vertikallast über die Kupplungen zwi- sehen den einzelnen Wagenkasten auf die Enddreh- gestelle übertragen.
Gemäss der zweiten, in der Fig. 2 gezeigten Aus führungsform weisen die Glieder 12, 13 und 14 wie- derum Wagenkasten 15, 16 und 17 auf, die mittels Drehgestelle 18, 19 und 20 abgestützt sind. Die Untergestelle der Wagenkasten sind d'urc'h kugel förmige Verbindungsstücke 21 miteinander verbun den, während im Bereiche des Wagendaches horizon- tale, auf Zug und Druck wirkende Anschläge 22 vorgesehen sind.
Auch hier besitzen die Wagen kasten nur einen Freiheitsgrad der Bewegung, das heisst sie können sich beim Kurvenlauf gegeneinander um einen bestimmten Winkel verdrehen. Durch die Anschläge wird eine gewisse Anpassung der einzelnen Zugsglieder an seitliche Überhöhungen der Geleise zugelassen. Auch bei dieser Ausführung erfolgt die Lastverteilung auf die drei Drehgestelle in Abhän gigkeit der Federsteifigkeit der Drehgestellfederungen.
Sowohl bei der Ausführung nach der Fig. 1 als auch nach der Fig. 2 kann durch eine sehr weiche Fe derung des Mitteldrehgestelles ein Teil der Vertikal last auf die Enddrehgestelle übertragen werden.
Unter Umständen kann jedoch vorkommen:, dass beim Über- fahren von Bodenunebenheiten, das heisst beim über gang vom horizontalen Geleise in eine Steigung und umgekehrt, sich die Lasten auf die einzelnen Dreh gestelle unerwünscht ändern, was für die Adhäsion der Triebdrehgestelle sich nachteilig auswirkt. So kann beim Übergang von einer grossen Geleisesteigung in eine kleinere oder entgegengesetzt gerichtete Stei gung die Adhäsion der Triebdrehgestelle stark ab nehmen.
Um diesen Nachteil zu beheben, kann das mittlere Drehgestell mit einer druckregulierten Luftfederung ausgerüstet sein, 'bei welcher der Feder- druck unter allen Belastungen konstant gehalten wird. Der konstant gehaltene Druck bewirkt eine Kon stanthaltung der Belastung auf das mittlere Dreh gestell' auch beim Befahren von Gefällsbrüchen. Aber auch bei dieser Federung ist dafür gesorgt, dass ihre Charakteristik flacher ist als bei den Enddrehgestellen.
Articulated vehicle train The present invention relates to an articulated vehicle train which consists of at least two elements and has at least three bogies.
In the known articulated vehicle trains, completely articulated connections are provided between the elements, in which arrangement the load is automatically distributed over the three bogies. In practice, however, a very specific load distribution is prescribed depending on the arrangement of the motor bogies. Are z. If, for example, the two final turning orders are driven, a certain proportion of the total train weight must act on these bogies, otherwise the necessary adhesion is not guaranteed.
It has already been proposed to design the joints between the car body in such a way that a spherical joint is used in the undercarriage, while in the upper part the car bodies are mutually supported by horizontally mounted springs. In this way, a certain proportion of the vertical load is shifted to the end bogies. However, this arrangement has the disadvantage that it is complicated.
Furthermore, such an articulated connection is unstable, so that the individual car bodies can perform uncontrollable vibrations against one another. The purpose of the invention is to avoid the disadvantages mentioned.
The articulated wagon train according to the invention is characterized in that the elements are rigidly connected to each other in the vertical longitudinal plane, the middle bogie having a suspension with flatter characteristics than the end bogies.
In this way it is achieved that the car bodies have only one degree of freedom of movement against each other, that is to say they can only rotate against each other by a certain angle when cornering. The load distribution on the three bogies when driving on a horizontal, straight track is only determined by the spring stiffness of the bogie suspension.
Due to the very soft suspension of the center bogie in relation to the end bogies, part of the vertical load is transferred to the end bogies via the joints between the individual car bodies.
On the accompanying drawing, two Ausfüh approximately examples of the subject invention are shown, namely Fig. 1 shows a schematic sketch of a first imple mentation and Fig. 2 shows a second embodiment of an articulated car train. According to the Ausfüh tion shown in FIG. 1, the articulated vehicle train has three members 1, 2 and 3, each of which has a car body 4, 5 and 6 and associated bogies 7, 8 and 9.
The links 1, 2 and 3 are connected to one another by couplings 10 and 11, which act rigidly in the vertical longitudinal plane, so that the cars only cost each other:
have a degree of freedom of movement, which means that they can only rotate against each other by a certain angle when cornering. According to the embodiment shown, a coupling 10 or 11 is provided both in the area of the roof and in the area of the underframe.
When driving on a horizontal, straight track, the load distribution on the three bogies is determined by the spring stiffness of the bogie suspension. By a softer suspension of the middle bogie. compared to the end bogies, part of the vertical load is transferred to the end bogies via the couplings between the individual car bodies.
According to the second embodiment shown in FIG. 2, the links 12, 13 and 14 in turn have car bodies 15, 16 and 17 which are supported by means of bogies 18, 19 and 20. The subframes of the car bodies are d 'urc'h spherical connecting pieces 21 connected to one another, while horizontal stops 22 acting on tension and pressure are provided in the area of the car roof.
Here, too, the car bodies only have one degree of freedom of movement, which means that they can twist against each other by a certain angle when cornering. The stops allow a certain adjustment of the individual tension members to the lateral elevations of the tracks. In this version, too, the load is distributed to the three bogies depending on the spring stiffness of the bogie suspension.
Both in the embodiment according to FIG. 1 and according to FIG. 2, part of the vertical load can be transferred to the end bogies by a very soft springing of the central bogie.
Under certain circumstances, however, it can happen that when driving over uneven ground, i.e. when transitioning from a horizontal track to an incline and vice versa, the loads on the individual bogies change undesirably, which has a detrimental effect on the adhesion of the motor bogies. For example, when there is a transition from a steep track gradient to a smaller or oppositely directed gradient, the adhesion of the motor bogies can decrease significantly.
To remedy this disadvantage, the middle bogie can be equipped with a pressure-regulated air suspension, in which the spring pressure is kept constant under all loads. The pressure kept constant causes the load on the middle bogie to be kept constant even when driving on downhill slopes. But even with this suspension, it is ensured that its characteristics are flatter than with the end bogies.
