Abstract
Description
Die Erfindung betrifft ein Sekundärfedersystem für Fahrwerke an Niederflurfahrzeugen, insbesondere an schienengebundenen Niederflurfahrzeugen zur Aufnahme von Vertikalbewegungen zwischen Fahrwerk und Wagenkasten des Niederflurfahrzeuges.The invention relates to a secondary spring system for chassis on low-floor vehicles, especially on rail-bound low-floor vehicles for recording of vertical movements between the chassis and the body of the low-floor vehicle.
Generell verfügen Fahrwerke für Schienenfahrzeuge über Primärfederelemente zur federnden Abstützung der an Schwingen gelagerten Einzelräder oder Radachsen gegenüber dem Fahrwerksrahmen und über Sekundärfederelemente zur federnden Abstützung der Vertikalbewegung des Wagenkastens gegenüber dem Fahrwerksrahmen.In general, bogies for rail vehicles have primary spring elements for resilient support of single wheels or wheel axles mounted on rockers opposite the chassis frame and via secondary spring elements for resilient support of the vertical movement of the car body opposite the chassis frame.
Gemäß der DE 42 38 574 A1 ist ein Fahrwerk für Niederflurwagen bekannt, bei dem der Wagenkasten vertikal über Sekundärfedern auf dem Fahrwerkrahmen abgestützt ist. Als Sekundärfedern kommen Schraubenfedern zum Einsatz, die in Taschen gelagert sind, die zu beiden Seiten des Fahrzeugrahmens ausgebildet sind. Mit dieser Ausführung gelingt es, die Niederflurigkeit des Niederflurfahrzeuges zu verbessern.According to DE 42 38 574 A1, a chassis for low-floor wagons is known from which the car body vertically above secondary springs on the chassis frame is supported. Coil springs are used as secondary springs Bags are stored, which are formed on both sides of the vehicle frame are. With this design, the low-floor vehicle's low-floor vehicle succeeds to improve.
Gemäß der DE 37 23 833 A1 sind gleichfalls als Schraubenfedern ausgebildete Sekundärfedern eingesetzt, die, im Drehgestell des Schienenfahrzeuges angeordnet, den Wagenkasten abstützen.According to DE 37 23 833 A1 are also designed as coil springs Secondary springs used, which, arranged in the bogie of the rail vehicle, support the car body.
Ein gemeinsamer Nachteil des Einsatzes von Schraubenfedern als Sekundärfedern besteht darin, dass infolge der vertikalen Wirkungsrichtung der Federn das sekundäre Federsystem eine vertikale Dimension aufweist, die sich bis in den Bodenbereich des Wagenkastens erstreckt und damit ein durchgängig ebener Wagenboden nicht erreichbar ist. Die die Bauhöhe des sekundären Federsystems bestimmende Größe ist die Blocklänge der Feder, d.h. der Zustand der Schraubenfeder, wenn alle Windungen anliegen. Die im Schienenfahrzeugbau zum Einsatz gelangenden Schraubenfedern haben einen, bezogen auf die Blocklänge, geringen Federweg.A common disadvantage of using coil springs as secondary springs is that due to the vertical direction of action of the springs secondary spring system has a vertical dimension that extends down to the floor area of the car body and thus a consistently flat car floor is not available. The height of the secondary spring system the determining size is the block length of the spring, i.e. the condition of the coil spring, when all turns are present. The in rail vehicle construction for Helical springs used have one, based on the block length, low travel.
Der Erfindung liegt die Aufgabe zugrunde, ein Sekundärfedersystem für Fahrwerke an Niederflurfahrzeugen bereitzustellen, dessen vertikale Ausdehnung im wesentlichen durch den konstruktiven Abstand bestimmt wird, der zwischen Fahrwerk und Wagenkasten besteht, um einen vertikalen Ausgleich zu ermöglichen.The invention has for its object a secondary spring system for running gear to provide on low-floor vehicles, the vertical extent of which is essentially determined by the constructive distance between The undercarriage and body are made to allow vertical compensation.
Die Aufgabe wird durch die Merkmale des selbständigen Anspruches 1 gelöst.The object is achieved by the features of
Das Sekundärfedersystem besteht aus mehreren untereinander beabstandeten Sekundärfedern, die einerseits mit dem Fahrgestell und andererseits mit dem Wagenkasten verbunden sind.The secondary spring system consists of several spaced apart Secondary springs on the one hand with the chassis and on the other hand with the Car body are connected.
Bestandteil der Sekundärfeder ist eine zwischen Wagenkasten und Fahrwerk zur Aufnahme der vertikalen Schwingungen im Fahrwerk angeordnete erste vertikal einfach wirkende Zylinder/ Kolbeneinheit zur Kraftaufnahme. Der Zylinder der ersten Zylinder/ Kolbeneinheit ist mit dem Fahrwerk fest verbunden, während deren Kolben mit seiner Kolbenstange am Wagenkasten angelenkt ist - oder umgekehrt- .Part of the secondary spring is one between the body and chassis Recording the vertical vibrations in the chassis arranged first vertically single-acting cylinder / piston unit for force absorption. The cylinder of the first cylinder / piston unit is firmly connected to the chassis while whose piston is articulated with its piston rod on the car body - or vice versa- .
Der Hubraum der ersten Zylinder/ Kolbeneinheit ist über eine Hydraulikleitung mit dem Hubraum einer zweiten Zylinder/ Kolbeneinheit, die zur ersten Zylinder/Kolbeneinheit beabstandet und lageunabhängig im Schienenfahrzeug angeordnet ist, verbunden. Die zweite Zylinder/ Kolbeneinheit steht mit einer Schraubenfeder derart in Wirkverbindung, dass die Schraubenfeder mit ihrem einen Ende am Zylinder 7 abgestützt und an ihrem anderen Ende über den Kolben der zweiten Zylinder/ Kolbeneinheit beaufschlagbar ist.The displacement of the first cylinder / piston unit is via a hydraulic line with the displacement of a second cylinder / piston unit leading to the first cylinder / piston unit spaced and independent of location in the rail vehicle is connected. The second cylinder / piston unit stands with a coil spring in operative connection so that the coil spring with its one End supported on the cylinder 7 and at its other end via the piston second cylinder / piston unit can be acted upon.
Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert. Die dazugehörigen
Zeichnungen zeigen in
Fig. 1 zeigt das Schema einer einzelnen erfindungsgemäßen Sekundärfeder. Die
Feder besteht aus einer ersten Zylinder/ Kolbeneinheit 1, die in vertikaler Wirkrichtung
anstelle der dem bekannten Stand der Technik entsprechenden, als
Schraubenfeder ausgebildeten Sekundärfeder angeordnet ist, und die der Aufnahme
der Kräfte dient, die durch die bei Fahrt zwischen Fahrwerk11 und Wagenkasten
12 auftretenden Schwingungen erzeugt werden. Die Zylinder/ Kolbeneinheit
1 besteht aus einem Zylinder 2, der auf dem Fahrwerk 11 fest angeordnet
ist. Im Zylinder 2 bewegt sich ein einfach wirkender Kolben 3, dessen
Kolbenstange 4 sich in Richtung des Wagenkastens 12 erstreckt und auf der sich
der Wagenkasten 12 abstützt. Selbstverständlich kann gleichwirkend bei kinematischer
Umkehr der Zylinder 2 dem Wagenkasten 12 und der Kolben 3 dem
Fahrwerk 11 zugeordnet sein.Fig. 1 shows the diagram of a single secondary spring according to the invention. The
Spring consists of a first cylinder /
Die Zylinder/ Kolbeneinheit 1 ist über eine Hydraulikleitung 5 mit einer zweiten
Zylinder/ Kolbeneinheit 6 verbunden. Die Zylinder/Kolbeneinheit 6 dient der
Kraftabgabe der Sekundärfeder und kann an beliebiger Stelle des Fahrwerkes
11 angeordnet sein, wobei die Wirkungsrichtung und damit die Lage der Zylinder/
Kolbeneinheit 6 beliebig gewählt werden kann.The cylinder /
Die Zylinder/ Kolbeneinheit 6 besteht gleichfalls aus einem fest angeordneten
Zylinder 7 und einem darin geführten einfach wirkenden Kolben 8. Den Zylinder
7 umgibt eine Schraubenfeder 9, die mit ihrem einen Ende am Zylinder 7 fixiert
ist und mit ihrem anderen Ende an das freie Ende der Kolbenstange 10 angeschlossen
ist. Das Zusammenwirken von Zylinder/ Kolbeneinheit 6 und Schraubenfeder
9 erfolgt in gleicher Wirkrichtung. Die Schraubenfeder 9 ist so ausgelegt,
dass sie den Anforderungen als Feder- und Dämpfungselement eines Sekundärfedersystems
für den gewählten Einsatz an Schienenfahrzeugen genügt.The cylinder /
Nachfolgend wird das erfindungsgemäße Sekundärfedersystem in seiner Wirkungsweise
näher beschrieben. Ursächliche Aufgabe des Sekundärfedersystems
ist der Ausgleich von Schwingungen zwischen Fahrwerk11 und Wagenkasten 12
eines Schienenfahrzeuges, die während der Fahrt durch Unebenheiten des
Schienenweges, durch Fremdkörper, Traktionseinflüsse und dergleichen auftreten
können.The mode of operation of the secondary spring system according to the invention is described below
described in more detail. Causal task of the secondary spring system
is the compensation of vibrations between the
Die Schwingungen zwischen Fahrwerk 11 und Wagenkasten 12 stellen sich als
wechselnde Abstandsänderungen zwischen den beiden Teilen dar. Diese Abstandsänderung
wird von der Zylinder/ Kolbeneinheit 1 in der Weise aufgenommen,
dass der den Wagenkasten 12 über die Kolbenstange 4 tragende Kolben
3 bei Verringerung des Abstandes in den Zylinder 2 hinein bewegt wird.
Damit verbindet sich eine Verringerung des Hubraumes des Zylinders 2 und
damit eine Verdrängung des Hydrauliköls aus der Zylinder/ Kolbeneinheit 1.The vibrations between the
Über die Hydraulikleitung 5 wird das verdrängte Volumen dem Zylinder 7 der
Zylinder/ Kolbeneinheit 6 zugeführt. In der Folge wird der Kolben 8 aus dem
Zylinder 7 bewegt, was mit einer Beaufschlagung der die Zylinder/ Kolbeneinheit
6 umgebenden Schraubenfeder 9 einhergeht. Auf diese Weise nimmt die
Schraubenfeder 9 mittelbar die durch die Verringerung des Abstandes zwischen
Fahrwerk 11 und Wagenkasten 12 ausgelöste Kraft auf. Die Begrenzung des
Federweges der Schraubenfeder 9 erfolgt durch eine Begrenzung des Hubes des
Kolbens 8 im Zylinder 7.Via the
In umgekehrter Weise wirken die beschriebenen Elemente zusammen, wenn sich
der Abstand zwischen Fahrwerk 11 und Wagenkasten 12 vergrößert. Der sich
dabei einstellende belastungsarme Zustand der Zylinder/ Kolbeneinheit 1 führt
dazu, dass sich die Schraubenfeder 9 entspannt. Dabei wird der Kolben 8 durch
die Schraubenfeder 9 in den Zylinder 7 gedrängt und das Hydrauliköl über die
Hydraulikleitung 5 dem Zylinder 2 der Zylinder/ Kolbeneinheit 1 zugeführt. Der
sich aus dem Zylinder 2 heraus bewegende Kolben 3 folgt der Vergrößerung
des Abstandes zwischen Fahrwerk 11 und Wagenkasten 12 innerhalb festgelegter
Grenzen und übt dabei durch die Wirkung der Schraubenfeder 9 eine
Dämpfung der Bewegung des Wagenkastens 12 aus.Conversely, the elements described work together when there are
the distance between the
Das hydraulische Grundkonzept des Sekundärfedersystems hat den Vorteil, daß
durch bekannte hydraulische Bauelemente auf einfache Weise auf das Schwingungsverhalten
des Wagenkastens 12 Einfluß genommen werden kann.The basic hydraulic concept of the secondary spring system has the advantage that
through known hydraulic components in a simple way on the vibration behavior
the
Über einen parallel geschalteten Druckspeicher 13 wird nach Erreichen des
Festausschlages des Kolbens 8 im Zylinder 7 eine Progressivität der Kennlinie
erzeugt, so dass ein abruptes Abbrechen des Federweges vermieden wird.Via a
Bei Verwendung eines geeigneten Drosselventils 14 in der Hydraulikleitung 5
dient das Sekundärfedersystem gleichzeitig als Federdämpfer, so dass auf zusätzliche
Schwingungsdämpfer verzichtet werden kann. When using a
Ein weiterer Vorteil der beschriebenen Anordnung besteht darin, daß durch das zusätzliche Einspeisen eines festgelegten Volumens an Hydrauliköl ein Höhenausgleich des Fahrzeuges infolge Radreifenverschleißes und Toleranzen möglich ist, so dass weitere Beilagen nicht erforderlich sind.Another advantage of the arrangement described is that additional feed of a defined volume of hydraulic oil a height compensation of the vehicle due to tire wear and tolerances is, so that additional inserts are not required.
Der wesentlichste Vorteil des erfindungsgemäßen Sekundärfedersystems besteht
jedoch darin, dass mit der Anordnung der Zylinder/ Kolbeneinheit 1 zwischen
dem Fahrwerk 11 und dem Wagenkasten 12 eine weitere Verringerung der
Bauhöhe des in diesem Bereich wirkenden Bauteils verbunden ist. Während die
Bauhöhe bei der Verwendung der herkömmlichen Schraubenfeder durch die
Blocklänge der Schraubenfeder bestimmt ist, kann die Bauhöhe der Zylinder/Kolbeneinheit
1 auf die Länge des Federweges der herkömmlichen Ausführung
minimiert werden. Das eigentliche und für den Schwingungsausgleich notwendige
Federelement kann in Wirkverbindung mit der zweiten Zylinder/ Kolbeneinheit
6 an einer beliebigen Stelle und in einer beliebigen Lage im Fahrzeug angeordnet
sein und nimmt damit keinen Einfluß auf die konstruktive Dimensionierung
des Sekundärfedersystems. Dieser Umstand wirkt sich somit vorteilhaft
auf die weitere Verbesserung der Niederflurigkeit bei Niederflurfahrzeugen aus.The main advantage of the secondary spring system according to the invention is
however, in that with the arrangement of the cylinder /
Die Charakteristik der Schraubenfeder 9 kann vom vorgegebenen Hub der Zylinder/
Kolbeneinheit 1 unabhängig und bezogen auf den Anwendungsfall optimiert
werden, indem der Durchmesser des Kolbens 8 gegenüber dem Durchmesser
des Kolbens 3 geringer ausgelegt wird. Der damit verbundene größere
Federweg der Schraubenfeder 9 ermöglicht eine feinfühligere Funktion des Sekundärfedersystems.The characteristic of the coil spring 9 can vary from the predetermined stroke of the cylinder /
Fig. 2 macht die Position der Zylinder/ Kolbeneinheit 1 im beschriebenen Ausführungsbeispiel
deutlich. An Stelle der bisher eingesetzten vertikal wirkenden
Schraubenfedern werden die Zylinder/ Kolbeneinheiten 1 mit minimierter Bauhöhe
positioniert. Die Zylinder/ Kolbeneinheiten 6 mit den dazugehörigen
Schraubenfedern 9 liegen unterhalb des Querträgers des Fahrwerkes 11 horizontal
und quer zur Fahrtrichtung des Schienenfahrzeuges und nehmen somit
keinen Einfluß auf die Bauhöhe des Systems. Fig. 2 makes the position of the cylinder /
