Abstract

A bogie or truck for high-speed rail vehicles or railway cars includes an H-shaped bogie or truck frame, primary springs cushioning the bogie frame, and a lateral bolster being movable relative to the bogie frame, receiving a coach or car body and being cushioned relative to the bogie or truck frame by air springs. The object is to provide a bogie with a low number of contact points with the coach body, which allows a configuration for rotational retardation, which has a minimum structural width and low weight, which permits small air spring bellows, which allows the installation of additional air reservoirs for the air springs below the lateral bolster and which has additional assemblies disposed at locations which keep the bearing components free from bending or torsional stresses. According to the invention, each air spring is supported directly on the side wall of the bogie frame. The lateral bolster carries friction plates on its upper surface near its transverse ends above its bearing on the air spring for supporting the coach body. The lateral bolster is movable relative to the bogie frame only vertically and horizontally transversely within a defined path and is guided horizontally in the longitudinal direction with play in guides of the bogie frame. The lateral bolster is connected to the coach body through a journal which transmits only horizontal forces, and can be freely rotated with the bogie frame relative to the coach body.

Description

Die Erfindung betrifft ein Drehgestell für schnellauffähige Schienenfahrzeuge mit einem H-förmigen Drehgestellrahmen, den Drehgestellrahmen gegenüber den Achsen abfedernden Primärfedern und einem gegenüber dem Drehgestellrahmen vertikal und horizontal quer beweglichen, den Wagenkasten des Schienenfahrzeuges aufnehmenden Wiegenquerträger, der gegenüber dem Drehgestellrahmen über pneumatische Sekundärfedern (Luftfedern) abgefedert und mit einer Drehhemmung versehen ist.The invention relates to a bogie for high-speed rail vehicles with an H-shaped bogie frame, the bogie frame with respect to the axles cushioning primary springs and a transverse and vertically horizontally movable with respect to the bogie frame, receiving the carriage body of the rail vehicle, the opposite to the bogie frame via pneumatic secondary springs (air springs) cushioned and provided with an anti-rotation device.

Drehgestelle für schnellauffähige Schienenfahrzeuge werden heute zum Teil mit einer als Sekundärfeder angeordneten Luftfeder versehen, um einerseits die Übertragung des Körperschalls zwischen dem Drehgestell und dem Wagenkasten zu unterbrechen und andererseits neben dem ermöglichten Niveauausgleich des Wagenkastens bei unterschiedlichen Beladungen einen optimalen Federungskomfort zu erhalten. Nachteilig bei den aus der Praxis bekannten Drehgestellen dieser Bauart ist in der Regel das Ausdrehen des Wagenkastens gegenüber dem Drehgestell innerhalb der Luftfeder, das eine ungünstige Scherbeanspruchung des Luftfederbalges erzeugt sowie die Federung nachteilig beeinflußt, unerwünscht hohe Rückstellkräfte beim Bogenlauf erzeugt und große Luftfederbälge erforderlich macht. Außerdem ist eine Vielzahl von Koppelstellen zwischen Wagenkasten und Drehgestell erforderlich, die hohe Erstellungskosten, einen hohen Zeitaufwand beim Drehgestelltausch und vermehrte Körperschallübertragung verursachen. Bei den Drehgestellen, die zwischen Wagenkasten und Drehgestell einen Wiegenträger angeordnet haben, wobei zwischen Wiegenquerträger und Drehgestellrahmen die Luftfeder angeordnet ist, wird zwar zum Teil ein Ausdrehen innerhalb der Luftfeder vermieden, jedoch ist der Aufwand an Bauteilen für die Anordnung der Luftfeder innerhalb des Drehgestells sehr hoch und ungünstig und der Aufwand für die erforderlichen Drehhemmungselemente unwirtschaftlich.
Drehgestelle für schnellauffähige Schienenfahrzeuge erfordern einen hohen Aufwand bezüglich der Erzielung der erforderlichen Laufstabilität. Insbesondere bei den Drehgestellen, die zur Erzielung einer hohen Laufleistung mit Radsätzen mit "Verschleißprofil" ausgerüstet sind, müssen neben erforderlichen Vertikal- und Querdämpfern und Wankstützen auch Drehhemmungen angeordnet sein, die das Schlingern des Drehgestells behindern. Diese Drehhemmungen sind üblicherweise aufwendig hydraulisch wirkend ausgebildet und mit zu großer Freigängigkeit versehen, sowie relativ störanfällig und bilden dadurch ein Sicherheitsrisiko.Bogies for high-speed rail vehicles are today partially equipped with an air spring arranged as a secondary spring, on the one hand to interrupt the transmission of structure-borne noise between the bogie and the car body, and on the other hand to obtain optimum suspension comfort in addition to the level compensation of the car body that is possible with different loads. A disadvantage of the bogies of this type known from practice is usually the turning of the car body relative to the bogie within the air spring, which creates an unfavorable shear stress on the air bellows and adversely affects the suspension, generates undesirably high restoring forces during sheet travel and requires large air bellows. In addition, a large number of coupling points between the car body and the bogie are required, which cause high production costs, a high expenditure of time when exchanging the bogie and increased transmission of structure-borne noise. In the bogies, which have a cradle between the car body and the bogie, with the air spring being arranged between the cradle crossmember and the bogie frame, turning out within the air spring is avoided in part, but the expenditure on components for the arrangement of the air spring within the bogie is very high high and inconvenient and the effort for the required anti-rotation elements uneconomical.
Bogies for high-speed rail vehicles require a lot of effort to achieve the required running stability. In particular in the bogies, which are equipped with wheelsets with a "wear profile" to achieve high mileage, in addition to the necessary vertical and transverse dampers and anti-roll supports, there must also be anti-rotation devices that prevent the bogie from rolling. These escapements are usually designed to be hydraulically complex and have too much freedom of movement, as well as being relatively susceptible to faults, and thus constitute a safety risk.

Ein Drehgestell der genannten Art ist beispielsweise aus der DE-OS 26 11 924 bekannt. Hierbei ist mittig auf dem Wiegenquerträger eine Drehpfanne angeordnet, die den Wagenkasten aufnimmt und das Drehgestell gegenüber dem Wagenkasten horizontal führt. Der Wiegenquerträger lagert über Luftfedern an seinen Querenden auf Wiegenfedertrögen, die mittels Pendel an den äußeren Langträgern des Drehgestells aufgehangen sind. Die Wiegenfedertröge und der Wiegenquerträger sind mittels quer zum Drehgestell und gelenkig angeordneter Schubstangen miteinander verbunden. Nachteilig bei dieser Ausführung ist die komplizierte und fertigungstechnisch aufwendige Aufhängung des Wiegenquerträgers mittels Federtrögen und Pendel an dem Rahmen des Drehgestells, die verminderte Wirkung der Drehhemmung zwischen Drehgestell und Wagenkasten, da die Längslenker zu elastisch sind und die erforderlich hohe Biegesteifigkeit des Wiegenquerträgers aufgrund der mittig über die Drehpfanne eingeleiteten Last des Wagenkastens, die zu einem hohen Gewicht des Wiegenquerträgers führt.A bogie of the type mentioned is known for example from DE-OS 26 11 924. Here, a rotary pan is arranged in the middle of the cradle cross member, which receives the car body and guides the bogie horizontally opposite the car body. The cradle cross member is supported by air springs at its cross ends on cradle spring troughs which are suspended by a pendulum on the outer long members of the bogie. The cradle spring troughs and the cradle crossmember are connected to each other by means of push rods arranged transversely to the bogie. A disadvantage of this design is the complicated and technically complex suspension of the cradle cross member by means of spring troughs and pendulums on the frame of the bogie, the reduced effect of the anti-rotation between the bogie and car body, because the trailing arms are too elastic and the required high bending strength of the cradle cross member due to the center the rotating pan initiated load of the car body, which leads to a high weight of the cradle cross member.

Bei der aus der DE-OS 23 37 771 vorbekannten Konstruktion lagert die Wiege direkt auf den Seitenlangträgern des Drehgestellrahmens über Gleitstücke. Zwischen dem Wiegenquerträger und dem Wagenkasten sind auf der Oberseite des Wiegenquerträgers Luftfedern angeordnet, die mit ihrer Oberseite unter dem Wagenkasten befestigt sind. Der Wiegenquerträger ist mit dem Wagenkasten über Gestänge vertikal beweglich verbunden, die ein Ausdrehen des Wiegenquerträgers gegenüber dem Wagenkasten und damit ein Verformen der Luftfeder verhindern. Das direkt über den Wiegenquerträger auf die Gleitstücke auf den Seitenwangen des Drehgestellrahmens wirkende Gewicht des Wagenkastens bewirkt hier vorteilhaft eine Drehhemmung des Drehgestells gegenüber dem Wiegenquerträger und damit auch gegenüber dem Wagenkasten. Nachteilig bei dieser Ausführung ist jedoch neben der erschwerten Zugängigkeit und aufwendigen Montage des Drehgestells mit seinen Luftfedern und dem Gestänge zur Ansteuerung des Wiegenquerträgers an dem Wagenkasten die erforderliche zusätzliche Anordnung eines Zug-Druckelementes, das den Drehgestellrahmen mit dem Wagenkasten verbindet. Nachteilig ist weiter die tiefe Anordnung der Gleitstücke im Bereich von Flugschnee und aufgewirbeltem Schmutz, die die Wirkung der Drehhemmung nachteilig beeinflussen.In the construction known from DE-OS 23 37 771, the cradle is mounted directly on the side members of the bogie frame via sliders. Between the cradle cross member and the car body, air springs are arranged on the top of the cradle cross member, which are attached with their top under the car body. The cradle cross member is vertically movably connected to the body via rods which prevent the cradle cross member from turning out relative to the body and thus preventing the air spring from being deformed. This directly over the cradle cross member on the sliders weight of the car body acting on the side walls of the bogie frame advantageously brings about an anti-rotation of the bogie with respect to the cradle cross member and thus also with respect to the car body. A disadvantage of this design, however, in addition to the difficult access and complex assembly of the bogie with its air springs and the linkage to control the cradle cross member on the car body, the required additional arrangement of a push-pull element that connects the bogie frame to the car body. Another disadvantage is the deep arrangement of the sliders in the area of flying snow and whirled up dirt, which adversely affect the effect of the rotation inhibition.

Die Aufgabe vorliegender Erfindung bestand darin, ein Drehgestell zu schaffen, das sich durch eine geringe Anzahl von Kontaktpunkten zum Wagenkasten auszeichnet, das die Möglichkeit einer redundanten und dennoch einfachen Anordnung von Drehhemmungen ermöglicht, das eine minimale Baubreite und niedriges Gewicht aufweist, das kleine Luftfederbälge zuläßt, das den Einbau von Zusatzluftbehältern für die Luftfedern unter dem Wiegenquerträger ermöglicht, Zusatzaggregate übersichtlich und an Stellen angeordnet hat, die tragende Bauteile von Biege- oder Torsionsspannungen freihalten und das einfach und zeitsparend unter dem Wagenkasten montierbar oder austauschbar ist.The object of the present invention was to provide a bogie which is characterized by a small number of contact points to the car body, which enables the possibility of a redundant yet simple arrangement of rotation inhibitions, which has a minimal overall width and low weight, which allows small air bellows , which allows the installation of additional air tanks for the air springs under the cradle crossmember, has arranged additional units clearly and in places, keeps the load-bearing components free from bending or torsional stresses and is easy and time-saving to install or replace under the car body.

Gemäß der Erfindung wird diese Aufgabe bei einem Drehgestell der eingangs genannten Art durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention, this object is achieved in a bogie of the type mentioned by the features of the characterizing part of claim 1.

Dadurch, daß jede Luftfeder direkt auf der Seitenwange des Drehgestellrahmens abgestützt ist, wird der Drehgestellrahmen vorteilhaft keinen zusätzlichen Biegemomenten, die bei wesentlich außermittigem Kraftangriff zur Seitenwange entstehen, ausgesetzt. Die Anordnung der Reibstücke auf dem Wiegenquerträger erfolgt etwa auf der gleichen Basis wie die Luftfederabstützung zum Drehgestellrahmen, so daß Biegebeanspruchungen des Wiegenquerträgers aus der Wagenkastenabstützung nur untergeordnet sind, wodurch eine gewichtssparende Ausbildung des Mittelteils des Wiegenquerträgers ermöglicht wird. Dadurch, daß der Wiegenträger gegenüber dem Drehgestellrahmen lediglich vertikal und horizontal quer innerhalb eines definierten Weges beweglich ist, wird ein freies Ausdrehen des Drehgestelles gegenüber dem Wagenkasten ermöglicht ohne seitliche Verformung der Luftfeder. Neben der Vermeidung von unzulässig großen Rückstellkräften aus der Luftfeder wird der Einbau von kleinvolumigen Luftfedern ermöglicht. Die Baubreite des Drehgestells wird vorteilhaft reduziert. Die Verbindung des Wiegenträgers mit dem Wagenkasten über einen lediglich Horizontalkräfte übertragenden Zapfen ermöglicht neben dem erwähnten freien Ausdrehen des Drehgestells gegenüber dem Wagenkasten eine leichte Montier- und Austauschbarkeit des Drehgestells unter dem Wagenkasten.Because each air spring is supported directly on the side cheek of the bogie frame, the bogie frame is advantageously none exposed to additional bending moments that occur when the side cheek is subjected to a substantially eccentric force. The arrangement of the friction pieces on the cradle cross member is done approximately on the same basis as the air spring support to the bogie frame, so that bending stresses of the cradle cross member from the car body support are only subordinate, whereby a weight-saving design of the middle part of the cradle cross member is made possible. The fact that the cradle relative to the bogie frame is only vertically and horizontally movable transversely within a defined path, a free turning of the bogie relative to the car body is possible without lateral deformation of the air spring. In addition to avoiding impermissibly large restoring forces from the air spring, the installation of small-volume air springs is made possible. The width of the bogie is advantageously reduced. The connection of the cradle to the car body via a pin which only transmits horizontal forces enables, in addition to the aforementioned free turning of the bogie relative to the car body, the bogie being easy to mount and replace under the car body.

Der Wiegenquerträger ist in Drehgestellängsrichtung über Führungselemente nahe seinen Querenden in Führungen des Drehgestellrahmes in seinen Bewegungen horizontal begrenzt. Die elastische Führung des Wiegenquerträgers in Drehgestellängsrichtung gewährleistet die gewünschte Längsentkopplung des Drehgestellrahmens zum Wagenkasten. Dadurch wird die Anregung von Wagenkastendurchbiegungsschwingungen klein gehalten, wobei gleichzeitig das Schlingern des Drehgestells mit dem Wiegenquerträger gegenüber dem Wagenkasten über die steife Drehhemmung behindert ist. Der Wiegenquerträger besteht aus einem Mittelteil mit je einem Wiegenquerträgerkopf an seinen Querenden, wobei die Anschlußelemente für Längsanschlag, Queranschlag, Vertikalanschlag und Vertikaldämpfer des Wiegenträgers, sowie die Anschlußelemente für Wankstütze, Drehhemmung, Luftfedersteuerventil, Luftfeder und die Drehhemmungsgleitstücke des Drehgestells in die Wiegenträgerköpfe integriert sind.The cradle cross member is horizontally limited in its movements in the longitudinal direction of the bogie via guide elements near its transverse ends in guides of the bogie frame. The elastic guidance of the cradle cross member in the longitudinal direction of the bogie ensures the desired longitudinal decoupling of the bogie frame from the body. As a result, the excitation of car body deflection vibrations is kept small, and at the same time the wobbling of the bogie with the cradle cross member relative to the car body is hindered by the rigid torsion resistance. The cradle cross member consists of a middle section with a cradle cross member head at each of its cross ends, whereby the connection elements for the longitudinal stop, cross stop, vertical stop and vertical damper of the cradle, as well as the connection elements for anti-roll support, anti-rotation, air spring control valve, air spring and the anti-rotation sliders of the bogie are integrated into the cradle heads.

Durch diese erfindungsgemäße Ausbildung des Wiegenquerträgers wird gewährleistet, daß sämtliche äußeren Kräfte, die bei hohen Geschwindigkeiten auftreten, von den Wiegenträgerköpfen über dessen Führungen direkt in den Drehgestellrahmen übergeleitet werden, ohne das Mittelteil des Wiegenquerträgers wesentlich auf Torsion oder Biegung zu beanspruchen.This inventive design of the cradle cross member ensures that all external forces that occur at high speeds from the cradle heads over the guides directly into the Bogie frames are transferred without significantly stressing the middle part of the cradle cross member on torsion or bending.

Erfindungsgemäß ist beidseitig des Wiegenquerträgers je eine Drehhemmung angeordnet, wobei jede Drehhemmung aus einer parallel zum Wiegenquerträger angeordneten Torsionswelle besteht, die mit an ihren Längsenden fest angeordneten vertikalen Zapfen elastisch an den Wiegenquerträgerköpfen gelagert ist und über sphärisch an ihren Enden gelagerte Lenkerstangen ebenfalls sphärisch gelagert mit den Längsenden der Langträger des Drehgestellrahmens verbunden ist.According to the invention, a rotation inhibitor is arranged on each side of the cradle cross member, each torsion inhibitor consisting of a torsion shaft arranged parallel to the cradle cross member, which is elastically mounted on the cradle cross member heads with vertical pins fixed at its longitudinal ends and also spherically supported on the handlebar rods with spherical ends Longitudinal ends of the long beam of the bogie frame is connected.

Durch diese doppelte Anordnung der Drehhemmung werden neben der Gewährleistung einer hohen Laufsicherheit auch bei Ausfall einer Drehhemmung die Längsentkopplung zwischen Drehgestell und Wagenkasten und sehr hohe Laufgeschwindigkeiten ermöglicht.With this double arrangement of the escapement, in addition to ensuring high running safety, the longitudinal decoupling between bogie and car body and very high running speeds are possible even if an escapement fails.

Erfindungsgemäß ist weiter beidseitig unterhalb des Wiegenquerträgers je ein Zusatzluftbehälter für jede Luftfeder angeordnet, jeder Zusatzluftbehälter mit einer kurzen und im Durchmesser großen Verbindungsleitung zu der jeweiligen Luftfeder versehen, wobei jeder Zusatzluftbehälter über eine Konsole am Wiegenquerträger befestigt ist. Durch die kurzen Verbindungsleitungen wird ein schnelles und gleichmäßiges Ansprechen der Luftfedern bei allen Belastungen erzielt. Durch die Anordnung der Zusatzluftbehälter am Wiegenquerträger werden diese sekundär abgefedert und vorteilhaft von hochfrequenten Beschleunigungen freigehalten.According to the invention, an additional air tank for each air spring is arranged on both sides below the cradle cross member, each additional air tank is provided with a short and large-diameter connecting line to the respective air spring, each additional air tank being fastened to the cradle cross member via a bracket. The short connecting lines ensure that the air springs respond quickly and evenly to all loads. By arranging the additional air tanks on the cradle crossmember, these are cushioned secondarily and advantageously kept free of high-frequency accelerations.

Insgesamt wird durch die Erfindung ein gleisfreundliches Drehgestell unter Verwendung von Radsätzen mit Verschleißprofil geschaffen, das sich durch niedriges Gewicht, hohe Laufruhe, absolute Laufsicherheit, einfache Funktion, übersichtliche Anordnung der Zusatzkomponenten und niedrige Beanspruchung der Einzelbauteile sowie leichte Tauschbarkeit auszeichnet.Overall, the invention creates a track-friendly bogie using wheelsets with a wear profile, which is characterized by low weight, smooth running, absolute running safety, simple function, clear arrangement of the additional components and low stress on the individual components as well as easy interchangeability.

Durch die Anordnung der wesentlichen Funktionselemente an den Wiegenquerträgerköpfen werden im mittleren Bereich des Drehgestells Freiräume zur Anordnung von Zusatzeinrichtungen geschaffen. Durch die geringe Breite des Drehgestells können die Ausdrehöffnungen der Wagenkastenaußenverkleidung vorteilhaft klein gehalten werden.The arrangement of the essential functional elements on the cradle cross member heads creates free spaces in the central region of the bogie for the arrangement of additional devices. Due to the small width of the bogie, the opening of the outer body paneling can advantageously be kept small.

Einzelheiten der Erfindung sind anhand eines Ausführungsbeispiels in der Zeichnung erläutert.Details of the invention are explained using an exemplary embodiment in the drawing.

Der etwa H-förmige Drehgestellrahmen besteht im wesentlichen aus zwei Langträgern 1 und zwei Querträgern 2, die die Langträger 1 verbinden und mit diesen fest verschweißt sind. Die Langträger 1 sind in ihrer Längsmitte nach unten verkröpft zur Aufnahme einer Luftfeder 3 etwa mittig auf ihren Obergurten. Ober- und Untergurte der Langträger 1 weisen keine Anschweißteile auf, die der Kraftübertragung dienen. Diese Maßnahme dient dem Leichtbau des Drehgestellrahmens. Auf den Luftfedern 3 ist über Wiegenquerträgerköpfe 4a ein aus den Wiegenquerträgerköpfen 4a und einem Wiegenquerträger-Mittelteil 4b bestehender Wiegenquerträger 4 gelagert. Die Luftfeder 3 ist mit ihrem Unterteil auf den Langträgern 1 und mit ihrem Oberteil unter den Wiegenquerträgerköpfen 4a befestigt.The approximately H-shaped bogie frame consists essentially of two long beams 1 and two cross beams 2, which connect the long beams 1 and are welded to them. The long beams 1 are cranked downwards in their longitudinal center to accommodate an air spring 3 approximately in the middle on their upper belts. The upper and lower straps of the long girders 1 have no weld-on parts that serve to transmit power. This measure serves the lightweight construction of the bogie frame. On the air springs 3, a cradle cross beam 4 consisting of the cradle cross beam heads 4a and a middle cradle cross member 4b is supported via cradle cross member heads 4a. The air spring 3 is fastened with its lower part on the long beams 1 and with its upper part under the cradle cross beam heads 4a.

Die Radsätze 5 des Drehgestells sind über Federblattlenker 6 am Langträger 1 geführt und über Primärfedern 7 und Stoßdämpfer 8 am Langträger 1 federnd gelagert.The wheel sets 5 of the bogie are guided via spring leaf links 6 on the long support 1 and are spring-mounted on the long support 1 via primary springs 7 and shock absorbers 8.

Das Wiegenquerträger-Mittelteil 4b ist kastenförmig ausgeführt, zu den Wiegenquerträgerköpfen hin verjüngt und mittig mit einer in Gummi gelagerten Drehzapfenführung 9 für den Drehzapfen des Wagenkastens versehen. Die Wiegenquerträgerköpfe 4a sind zweckmäßigerweise aus Guß- oder Schmiedestücken oder in Mischbauweise aus Schmiede- und Schweißteilen hergestellt und am Wiegenquerträger-Mittelteil 4b angeschweißt. Auf den Wiegenquerträgerköpfen 4a sind oberhalb der Luftfeder 3 Reibstücke 10 zur Aufnahme entsprechend ausgebildeter Gegenlager am Wagenkasten angeordnet. Über die Reibstücke 10 wird dabei die Vertikallast des Wagenkastens über die Wiegenquerträgerköpfe 4a und die Luftfedern 3 direkt in den Langträger 1 des Drehgestellrahmens abgesetzt. Zusammenwirkend mit den Gegenlagern unter dem Wagenkasten dienen die Reibstücke 10 als Reib-Drehhemmung. Durch die direkte Lasteinleitung des Wagenkastens über die Reibstücke, Wiegenquerträgerköpfe 4a und Luftfeder 3 in die Langträger 1 des Drehgestellrahmens wird eine Torsions- oder Biegebeanspruchung der Langträger 1 vermieden. Eine direkte Kontaktverbindung zwischen Wagenkasten und Drehgestell besteht lediglich über die Reibstücke 10 zur Aufnahme der Vertikallast und die Drehzapfenführung 9 zur Aufnahme der horizontalen Führungskräfte des Wagenkastens.The middle crossbeam part 4b is box-shaped, tapered towards the crossbeam heads and provided in the center with a pivot guide 9 mounted in rubber for the pivot of the body. The cradle cross member heads 4a are expediently made of cast or forgings or in a mixed construction from forged and welded parts and welded to the middle cradle member 4b. On the cradle crossbeam heads 4a 3 friction pieces 10 are arranged above the air spring for receiving correspondingly designed counter bearings on the car body. About the friction pieces 10, the vertical load of the car body on the cradle cross beam heads 4a and the air springs 3 is deposited directly into the long beam 1 of the bogie frame. In cooperation with the counter bearings under the car body, the friction pieces 10 serve as friction-rotation inhibition. Through the direct load introduction of the car body via the friction pieces, cradle crossbeam heads 4a and air spring 3 into the long girders 1 of the bogie frame, torsional or bending stress on the long girders 1 is avoided. A direct contact connection between the car body and the bogie only exists via the friction pieces 10 for receiving the vertical load and the pivot guide 9 for receiving the horizontal executives of the car body.

Der Wiegenquerträger 4 lagert auf dem Langträger 1 des Drehgestellrahmens über die Luftfedern 3. Horizontal in Drehgestell-Längsrichtung ist der Wiegenquerträger 4 über Gleitstücke 11 in Führungen 12 der Querträger 2 des Drehgestellrahmens mit geringem Spiel geführt. Die Führungen 11 sind elastisch ausgeführt und an den Querträgern 2 des Drehgestellrahmens angeordnet. In horizontaler Querrichtung ist der Wiegenträger 4 auf den Luftfedern 3 mit erforderlichem Pendelspiel zwischen Gegenlagern 13, die an den Querträgern 2 des Drehgestellrahmens angeordnet sind, über an den Wiegenträgerköpfen 4a angeordneten Wiegenqueranschlägen 14 in seinem Querspiel begrenzt, geführt. Die Wiegenqueranschläge 14 sind elastisch mit progressiver Federkennlinie ausgebildet.The cradle cross member 4 is supported on the long beam 1 of the bogie frame via the air springs 3. Horizontal in the longitudinal direction of the bogie, the cradle cross member 4 is guided with slides 11 in guides 12 of the cross member 2 of the bogie frame with little play. The guides 11 are elastic and arranged on the cross members 2 of the bogie frame. In the horizontal transverse direction, the cradle 4 is guided in its transverse play on the air springs 3 with the required pendulum play between counter bearings 13, which are arranged on the cross beams 2 of the bogie frame, via cradle cross stops 14 arranged on the cradle heads 4a. The cradle cross stops 14 are designed to be elastic with a progressive spring characteristic.

Auf beiden Längsseiten ist an dem Wiegenquerträger 4 je eine Torsionswelle 15 zur Drehhemmung angeordnet. Jede Torsionswelle 15 lagert dabei über fest an ihren Längsenden vertikal nach unten weisend angeordneten Lagerzapfen 16 mit Abstand elastisch in Lageraugen 17 des Wiegenquerträgerkopfes 4a. An jedem Längsende jeder Torsionswelle 15 ist je eine Lenkerstange 18 sphärisch gelagert, die mit ihrem anderen Ende ebenfalls sphärisch gelagert an dem jeweiligen Längsende des Langträgers 1 des Drehgestellrahmens angebunden ist. Durch die als Drehhemmung wirkende Torsionswelle 15 ist ein Längsspiel zwischen Wiegenquerträger 4 und den Querträgern 2 des Drehgestellrahmens und damit eine Längsentkopplung des Wiegenquerträgers 4 von dem Drehgestellrahmen gewährleistet. Bei Ausdrehung des Wiegenquerträgers 4 gegen den Drehgestellrahmen wird diese Ausdrehung jedoch durch die Drehhemmung (Torsionswelle) behindert. Beim Ausdrehen des Drehgestellrahmens gegenüber dem Wagenkasten bilden der Wiegenquerträger und der Drehgestellrahmen durch die Drehhemmung ein steifes Gebilde und behindern weitgehend ein Schlingern des Drehgestells. Durch die doppelte Anordnung der Drehhemmung beidseitig des Wiegenquerträgers wird eine große Steifigkeit gegen Ausdrehung, die bei hohen Geschwindigkeiten erforderlich ist und eine Erhöhung der Laufsicherheit gewährleistet.On both longitudinal sides, a torsion shaft 15 is arranged on the cradle cross member 4 to prevent rotation. Each torsion shaft 15 is supported at a distance via bearing pins 16, which are arranged vertically downwards at their longitudinal ends and are spaced elastically in bearing eyes 17 of the cradle cross member head 4a. At each longitudinal end of each torsion shaft 15, a handlebar 18 is spherically mounted, which is also connected spherically with its other end to the respective longitudinal end of the long beam 1 of the bogie frame. Due to the torsion shaft 15 acting as a rotation inhibitor, there is a longitudinal play between the cradle cross member 4 and the cross members 2 of the bogie frame and thus a longitudinal decoupling of the cradle cross member 4 guaranteed by the bogie frame. When the cradle cross member 4 is turned out against the bogie frame, however, this turning out is impeded by the rotation inhibition (torsion shaft). When the bogie frame is turned out relative to the car body, the cradle cross member and the bogie frame form a rigid structure due to the rotation inhibition and largely prevent the bogie from rolling. The double arrangement of the escapement on both sides of the cradle cross-member ensures great rigidity against rotation, which is necessary at high speeds and increases running safety.

Der Wiegenquerträger 4 ist weiter über je eine beidseitig desselben angeordnete Wankstütze (19 - 22) gegen Wanken des Wagenkastens gesichert. Die Wankstütze besteht dabei aus je einer Torsionswelle 19, die drehbar unter dem Querträger 2 des Drehgestellrahmens gelagert ist. An jedem Ende jeder Torsionswelle 19 ist je ein Hebel 20 fest angeordnet, der an seinem freien Ende sphärisch ein Pendel 21 trägt, das mit seinem anderen Ende ebenfalls sphärisch an einem Lager 22 des Wiegenquerträgerkopfes 4a (4) gelagert ist. Bei ungleichmäßiger Einfederung der Luftfeder 3 wird die Torsionswelle 19 tordiert und damit ein Wanken des Wiegenquerträgers 4 behindert.The cradle cross member 4 is further secured against rolling of the car body by means of a roll support (19 - 22) arranged on both sides thereof. The anti-roll bracket consists of a torsion shaft 19, which is rotatably mounted under the cross member 2 of the bogie frame. At each end of each torsion shaft 19 a lever 20 is fixedly arranged, which spherically carries a pendulum 21 at its free end, which is also spherically supported at its other end on a bearing 22 of the cradle cross member head 4a (4). If the air spring 3 is deflected unevenly, the torsion shaft 19 is twisted, thus preventing the cradle cross member 4 from swaying.

An den Wiegenträgerköpfen 4a ist weiter je ein Vertikaldämpfer 23 sphärisch gelagert, der mit seinem anderen Ende am langträger 1 des Drehgestellrahmens ebenfalls sphärisch gelagert ist. Jeder Wiegenquerträgerkopf weist zusätzlich Anschlüsse für Luftfedersteuerventil 24 auf. Wiegenquerdämpfer 30, die sphärisch am Querträger 2 des Drehgestellrahmens beziehungsweise an dem Wiegenquerträger 4 gelagert sind, dämpfen zusätzlich Querbewegungen des Wiegenquerträgers. Obere und untere Vertikalanschläge (25 bzw. 26) begrenzen den Federweg des Wiegenquerträgers 4.A vertical damper 23 is also each spherically mounted on the cradle carrier heads 4a, which is also spherically supported at its other end on the long beam 1 of the bogie frame. Each cradle cross member head additionally has connections for air spring control valve 24. Cradle damper 30, which is spherically mounted on the cross member 2 of the bogie frame or on the cradle cross member 4, additionally dampen transverse movements of the cradle cross member. Upper and lower vertical stops (25 and 26) limit the spring travel of the cradle cross member 4.

Der untere Vertikalanschlag 26 ist ein Gummifederelement und dient auch als sekundäre Notfeder bei Druckausfall in der Luftfeder, indem sich die Last aus dem Wagenkasten nur nach hier vollständig absetzt.The lower vertical stop 26 is a rubber spring element and also serves as a secondary emergency spring in the event of pressure loss in the air spring, in that the load from the car body only completely settles down here.

Beidseitig unterhalb des Wiegenquerträgers (4) ist an diesem je ein Zusatzluftbehälter (27) für jede Luftfeder (3) angeordnet, wobei jeder Zusatzluftbehälter (27) mit einer kurzen und im Durchmesser großen Verbindungsleitung (28) zu der jeweiligen Luftfeder (3) versehen ist. Hierbei ist jeder Zusatzluftbehälter (27) über eine Konsole (29) am Wiegenquerträger (4) befestigt, so daß die Zusatzluftbehälter (27) und der Wiegenquerträger (4) sekundär abgefedert sind und hochfrequente Beschleunigungen der Zusatzluftbehälter vermieden werden.An additional air tank (27) for each air spring (3) is arranged on each side below the cradle cross member (4), each Additional air tank (27) is provided with a short and large diameter connecting line (28) to the respective air spring (3). Each auxiliary air tank (27) is fastened to the cradle cross member (4) via a bracket (29), so that the auxiliary air tank (27) and the cradle cross member (4) are cushioned secondarily and high-frequency accelerations of the auxiliary air tank are avoided.
