Description
Die Erfindung betrifft ein Schienenfahrzeug gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a rail vehicle according to the Preamble of the first claim.
Es ist bei Schienenfahrzeugen ganz allgemein bekannt, zur Abstützung eines Wagenkastens auf einem darunter angeordneten Laufwerk mechanisch parallel zueinander oder in Serie zueinander angeordnete Federelemente vorzusehen. Versagt eines dieser Federelemente, bleibt die Wirkung des zugeordneten zweiten Federelementes erhalten. Bei Parallelschaltung tritt dabei jedoch eine wesentliche Verminderung der Stützkraft ein, während bei einer Serienanordnung eine große Baulänge in Wirkrichtung die Folge ist.It is generally known in rail vehicles for Support of a car body on an arranged below Mechanically parallel to each other or in series to provide mutually arranged spring elements. One fails of these spring elements, the effect of the assigned remains received second spring element. When connected in parallel however, a significant reduction in the supporting force while in a series arrangement a large length in Direction of action is the result.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Schienenfahrzeug gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch die bei gedrängter Bauweise unter üblichen Betriebsbedingungen aber auch bei Ausfall der Stützfunktion einer Stützjeder nur ein Federungselement wirksam ist.The invention is based, with one Rail vehicle according to the preamble of the first claim Measures to be taken by under-crowded construction normal operating conditions, but only one suspension element is effective even if the support function of a support fails is.
Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by characteristic features of the first claim.
Bei einem Aufbau eines Schienenfahrzeugs gemäß der Erfindung wird die Notfeder bei wirkungsmäßig parallel Zuordnung zum betriebsmäßig genutzten Stützaktuator nur dann beansprucht, wenn der Stützaktuator seine federnde Stützfunktion zumindest weitgehend verliert. Nur dann setzt der Anschlag, der mit dem gegenüber der Notfeder verstellbaren Ende des Stützaktuators verbunden ist, auf die zugewandte Stirnseite der Notfeder auf. Unter üblichen Betriebsbedingungen erfolgt also keine Beeinflussung der Funktion des Stützaktuators. Dagegen übernimmt die Notfeder im Versagensfalle des Stützaktuators die volle, vom Wagenkasten herrührende Belastung, wobei der Wagenkasten lediglich auf ein niedrigeres Niveau absinkt. Die Notfeder kann somit auf die tatsächliche Belastung des Wagenkastens abgestimmt und zu diesem Zweck mechanisch vorgespannt und im Längshub begrenzt sein, so daß der für den normalen Arbeitshub erforderliche freie Abstand zwischen der Notfeder und dem Anschlag gewährleistet ist. Der Aktuator ist insbesondere ein hydropneumatisch gesteuerter Zylinder, der demgemäß Federungseigenschaften aufweist und je nach den Betriebsbedingungen hinsichtlich der von ihm auszuübenden Kraft oder Streckung gesteuert wird. Das Zylindergehäuse dieses Aktuators ist vorzugsweise starr auf dem Fahrwerkrahmen festgesetzt, auf dem auch ein Ende der Notfeder aufsitzt. Der der Kolbenstange des Aktuators zugeordnete Anschlag kann dabei unmittelbar an der Kolbenstange befestigt sein. Bevorzugt ist er jedoch über einen nach Art eines Kugelgelenks ausgebildeten Gelenkverbinder mit dem freien Ende der Kolbenstange verbunden. Dadurch kann der Anschlag fest mit einer Platte eines Schiebeadapters verbunden werden, dessen demgegenüber in einer Ebene frei verstellbare Gegenplatte fest mit dem Boden des Wagenkastens verbunden ist. Der Schiebeadapter kann dabei insbesondere als Kugeltisch ausgebildet sein. Er ist zudem nur parallel zur Ebene des Wagenkastenbodens verstellbar.When building a rail vehicle according to the invention the emergency spring is in effect parallel assignment to operational actuator used only then if the support actuator at least its resilient support function largely loses. Only then does the stop that comes with the opposite of the emergency spring adjustable end of the support actuator is connected to the facing end of the emergency spring. So, under normal operating conditions, none Influencing the function of the support actuator. On the other hand the emergency spring takes over in the event of failure of the support actuator full load originating from the car body, the The body only drops to a lower level. The Emergency spring can thus be based on the actual load on the Car body tuned and mechanical for this purpose biased and limited in the longitudinal stroke, so that for the normal working stroke required free space between the Emergency spring and the stop is guaranteed. The actuator is especially a hydropneumatically controlled cylinder that accordingly has suspension properties and depending on the Operating conditions with regard to the force to be exerted or stretch is controlled. The cylinder housing this Actuator is preferably rigid on the chassis frame fixed, on which also sits one end of the emergency spring. The the piston rod associated with the actuator can stop be attached directly to the piston rod. Is preferred However, he has a trained in the manner of a ball joint Articulated connector connected to the free end of the piston rod. This allows the stop to be firmly attached to a plate Sliding adapters are connected, the opposite in a Level freely adjustable counter plate fixed to the bottom of the Car body is connected. The sliding adapter can in particular be designed as a ball table. He is also only adjustable parallel to the level of the car body floor.
Die Notfeder wird bevorzugt zylindrisch ausgebildet und konzentrisch zum Zylindergehäuse angeordnet. Auch der Anschlag ist dabei zylindrisch ausgeführt und im Durchmesser angepaßt, so daß er im Versagensfall des Aktuators verkantungsfrei auf die zugewandte Stirnseite der Notfeder aufsetzt und an der Außenmantelfläche des Zylindergehäuses vorbei die dort sitzende Notfeder niederdrücken kann. The emergency spring is preferably cylindrical and arranged concentrically to the cylinder housing. Even the attack is cylindrical and adjusted in diameter, so that it does not tilt in the event of actuator failure the facing end of the emergency spring touches down and on the Outer lateral surface of the cylinder housing past the one sitting there Can press down the emergency spring.
Um die Notfeder im Falle ihrer mechanischen Vorspannung hubbegrenzt festlegen zu können, ist ein gegebenenfalls mehrteiliger Begrenzungsanschlag vorgesehen, der vor das dem Anschlag zugewandten Ende der Notfeder greift und der andererseits auf dem Fahrwerkrahmen festsitzt. Bei dieser Anordnung wird die Notfeder sowohl vom Zylindergehäuse des Stützaktuators als auch von den im Außenbereich der Notfeder angeordneten Teilen des Stützanschlags gegen seitliches Ausknicken geführt.To the emergency spring in the event of its mechanical preload To be able to specify a stroke-limited setting is an option Multi-part limit stop provided before the Stop facing end of the emergency spring engages and the on the other hand stuck on the chassis frame. At this Arrangement is the emergency spring from both the cylinder housing Support actuator as well as the outside of the emergency spring arranged parts of the support stop against lateral Buckling led.

Von einem Fahrzeug, insbesondere einem Schienenfahrzeug, ist
ein Wagenkasten 1 schematisch angedeutet, unter dessen
Bodenwand 2 ein Laufwerk angeordnet ist. Das Laufwerk weist
zumindest eine Achse bzw. zwei Räder 3, vorliegend zwei
parallele Achsen bzw. vier Räder 3 auf. Die Räder 3 sind als
Schienenräder ausgebildet. Ein Laufwerkrahmen 4 stützt sich
dabei mit in Fahrtrichtung des Laufwerks verlaufenden
Längsträgern 5, welche über zumindest einen Querträger 6
miteinander verbunden sind, mittels Primärfedern 7 auf
Radlagerelementen 8 der Räder 3 ab und verkoppelt so die Räder
3 laufstabil untereinander. Etwa in der Mitte von zwei in
Laufrichtung hintereinander angeordneten Rädern 3 steht auf
jedem Längsträger 5 senkrecht zu der durch diese Längsträger 5
gebildeten Ebene auf jedem der Längsträger 5 eine
Verbindungsvorrichtung 9, 10, 11, über welche der Wagenkasten 1
mit seiner Bodenwand 2 auf dem Laufwerk abgestützt ist.From a vehicle, especially a rail vehicle
a
Die Verbindungsvorrichtung besteht aus einem Aktuator 9, einem
in alle Richtungen kippbaren Gelenkverbinder 10 und einem
Gleitverbinder 11, die alle in der Wirkungsrichtung des
Aktuators 9 mechanisch in Serie angeordnet sind. Die Aktuatoren
9, die insbesondere als Hydraulikzylinder ausgebildet sein
können, weisen zwei axial nur geradlinig gegeneinander
verstellbare Stellglieder 9.1 und 9.2 auf. Die Gelenkverbinder
10 können als Kreuz- oder Kugelgelenk, als gummielastisches
Gelenk oder nach Art eines Federstabes ausgebildet sein, um nur
Schwenkbewegungen mit begrenztem Schwenkausschlag nach allen
Richtungen in einer Ebene ausführen zu können. Der
Gleitverbinder 11 besitzt nur translatorische Freiheitsgrade in
einer Ebene, die parallel zur Bodenwand 2 des Wagenkastens 1
liegt. Die in einer Ebene richtungsungebundene Verschiebbarkeit
dieses Gleitverbinders ist dabei auf vorbestimmte Werte
begrenzt. Die Zuordnung der einzelnen Bauelemente 9, 10, 11 der
Verbindungsvorrichtung hat zur Wirkung, daß nur der Aktuator
Abstandsdifferenzen zwischen dem Drehgestell 4 und dem
Wagenkasten 1 ausgleichen kann, daß der Gelenkverbinder 10
richtungsunabhängig nur Kippbewegungen ausgleichen kann und daß
der Gleitverbinder 11 nur quer zur Verstellrichtung bzw. zur
Stellachse 15 des Aktuators 9 gerichtete Bewegungen ausgleichen
kann. Hierbei ist es vom Grundsatz unabhängig, in welcher
Reihenfolge die Bauelemente 9, 10, 11 aneinandergefügt sind,
wenn jeweils die beiden endständigen Elemente einerseits am
Fahrwerk 4 und andererseits am Wagenkasten 1 festgesetzt sind.The connecting device consists of an
Beim Ausführungsbeispiel sind die Zylindergehäuse 9.1 von
beispielsweise hydraulischen Aktuatoren 9 mit senkrecht
stehender Stellachse 15 jeweils auf einem der Längsträger 5
starr festgesetzt. Das andere Stellglied 9.2 des Aktuators 9
ist eine geradlinig nur entlang der Stellachse 15 verschiebbar
im Stellglied 9.1 geführte Stösselstange des Zylinderkolbens,
wobei das freie Ende dieses Stellgliedes 9.2 mit dem ersten
Schwenkglied 10.1 des Schwenkverbinders 10 starr verbunden ist,
während das zweite Schwenkglied 10.2 mit dem primären
Gleitglied 11.1 des Gleitelements 11 starr verbunden ist. Der
als Kugelgelenk ausgebildete Gelenkverbinder 10 läßt nur
Kippbewegungen zu, die zwischen den durch die Längsträger 5 und
die Bodenwand 2 gebildeten Ebenen auftreten. Um dabei auch
laterale Bewegungen zwischen den Fahrzeugteilen 1, 3, 4 oder
aus einer Verwindung der Ebenen die sich ergebende laterale
Verstellung ausgleichen zu können, ist der Gleitverbinder 11
vorgesehen, dessen primäres Gleitglied 11.1 mit dem zweiten
Schwenkglied 10.2 des Gelenkverbinders 10 und dessen sekundäres
Gleitglied 11.2 in fester Verbindung mit der Bodenwand 2 des
Wagenkastens 1 steht.In the embodiment, the cylinder housing 9.1 of
for example,
Der Aktuator 9 kann bei diesem Aufbau federnde Elemente
ersetzen, die als Sekundärfederung wirken. Er ist dazu
insbesondere als hydropneumatisch betriebener Zylinder
ausgebildet und läßt so nicht nur einen Höhenausgleich zwischen
Wagenkasten und Drehgestellrahmen zu, sondern kann auch
Federeigenschaften aufweisen, die sonst Wendelfedern,
Luftfedern oder dergleichen besitzen. Dabei ist die
Federcharakteristik den Bedürfnissen entsprechend steuerbar.
Die Kraftkopplung zwischen dem Wagenkasten und dem Drehgestell
zur Abstützung von Längs- und Querkräften kann konventionell z.
B. über Lenkerstangen-, Drehzapfen- oder Lemniskaten-Koppelelemente
oder elastische Puffer- bzw. Federelemente
erfolgen.In this construction, the
Die Verbindungsvorrichtung 9, 10, 11 kann selbstverständlich
auch gestürzt zwischen Wagenkasten 1 und Laufwerk 4 eingebaut
werden.The connecting
Um bei einem Versagen des Stützaktuators 9 ein in dieser Weise
ausgebildetes Schienenfahrzeug mit ausreichendem Komfort und
Sicherheit weiter betreiben zu können, ist konzentrisch zum
Stützaktuator 9 eine passive Notfeder 12 angeordnet. Die
Notfeder 12 sitzt dabei wie das Zylindergehäuse 9.1 des
Stützaktuators 9 mit einem axialen Ende auf einem Längsträger 5
des Fahrwerks 4 auf. Das gegenüberliegende, zum Wagenkasten 1
gerichtete Ende 12.1. der Notfeder 12 steht mit axialem Abstand
einem Ringanschlag 13 gegenüber, der ebenfalls konzentrisch zum
Stützaktuator 9 liegt und dessen der Notfeder 12 zugewandte
freie Ringstirnfläche 13.1 den gleichen Durchmesser wie die
Notfeder 12 besitzt. Der Ringanschlag 13 ist anderenends mit
dem primären Gleitglied 11.1 des Gleitelements 11 starr
verbunden. Da das primäre Gleitglied 11.1 keine
Lateralverschiebung gegenüber der Längsmittelachse 15 des
Stützaktuators durchführt, bleibt seine axiale Zuordnung zur
Notfeder 12 stets erhalten.In the event of a failure of the
Der freie axiale Abstand zwischen dem oberen Ende 12.1 der
Notfeder 12 und der zugewandten freien Ringstirnfläche des
ringförmigen Stützanschlags 13 ist dabei so bemessen, daß bei
dem unter üblichen Betriebsbedingungen auftretenden Hub des
Stützaktuators 9 keine Berührung zwischen Stützanschlag 13 und
Notfeder 12 eintritt. Bei sehr großen Belastungen oder bei
einem Versagen des Stützaktuators 9 senkt sich dagegen der
Stützanschlag 13 durch die Führung des Stützaktuators 9 axial
auf das obere freie Ende der Notfeder 12 ab. Die Notfeder ist
dabei so bemessen, daß sie die im normalen Betriebsfall
auftretenden statischen und dynamischen Kräfte zwischen
Laufwerk 4 und Wagenkasten 1 aufnehmen kann, wobei unter diesen
Betriebsbedingungen der Hub des Aktuators 9 noch nicht auf
seinen unteren Grenzwert zurückgeführt wird. Das
Federungsverhalten bleibt somit bei lediglich abgesenktem
Wagenkasten 1 erhalten. Der Innendurchmesser des ringförmigen
Stützanschlags 13 ist dabei größer als der Außendurchmesser des
Zylindergehäuses 9.1, um den Federweg durch Überfahren
entsprechend weit ausnutzen zu können. Der zur Notfeder 12 hin
offene Stützanschlag kann somit axial in überdeckung mit dem
Mantel des Kolbenzylinders 9 treten. The free axial distance between the upper end 12.1
Um die Notfeder 12 axial kurz halten zu können, ist sie
vorliegend in axialer Richtung mechanisch vorgespannt. Hierzu
liegt ihr freies, dem Stützanschlag 13 zugewandtes Ende 12.1 an
wenigstens einem Begrenzungsanschlag 14 an, der am
Fahrwerksrahmen 5 festgesetzt ist. Der Anschlag 14 ist
zweiteilig ausgeführt und an Halbschalen 14.1 vorgesehen,
welche im Bereich der Außenmantelfläche der Notfeder 12 in
diametraler Anordnung auf dem Langträger 5 festgesetzt sind.
Die Anschläge 14 ragen dabei als Ringflächenabschnitte in
radialer Richtung horizontal vor den äußeren Rand des freien
oberen Endes 12.1 der Notfeder 12. Zwischen den beiden
Begrenzungsanschlägen 14 verbleibt in Umfangsrichtung ein
freier Bereich, in welchem der Stützanschlag 13 jedenfalls über
die gesamte radiale Breite der Notfeder 12 an diametral
gegenüber liegenden Abschnitten aufsetzen kann. Die freie Länge
zwischen dem Aufstandspunkt der Notfeder 12 auf dem
Laufwerksrahmen 4 und dem Begrenzungsanschlag 14 ist kleiner
als die axiale Länge der entspannten Notfeder. Durch Wahl des
Abstandes zwischen Längsträger 5 und Begrenzungsanschlag 14
kann somit die Vorspannkraft der Notfeder 12 den
Betriebsbedingungen angepaßt werden.In order to keep the
