Mit der Entwicklung schienengebundener Transportsysteme als nichttrennbare Zugeinheiten, z.B. Nahverkehrszüge, ICE, STE, ergab sich auch der Bedarf an neuen Fahrwerken, die gleichzeitig zwei Wagenkästen abstützen können. Es gibt sogenannte.Jakobsdrehgestelle, speziell bei Straßenbahnen, die o.g. Eigenschaften aufweisen. Herkömmliche Konstruktionen sind aufwenig, schwer und damit teuer.With the development of rail-bound transport systems as inseparable Train units, e.g. Local trains, ICE, STE, also resulted in the need for new ones Undercarriages that can support two car bodies at the same time. There are so-called Jacob bogies, especially for trams, the above characteristics exhibit. Conventional designs are complex, heavy and therefore expensive.
Aufgabe der vorliegenden Erfindung ist es, ein völlig neues Fahrwerkskonzept zu schaffen, mit dem gattungsgemäße Transportsysteme ausgerüstet werden können, wobei besonderes Augenmerk auf einfache Konstruktion, leichte Montage, gute Wartungseigenschaften und preiswerte Fertigung gelegt wird. Das Fahrwerk soll leichter als herkömmliche Drehgestelle sein und für hohe Radlasten mit guter Bodenlaufeigenschaft ausgelegt sein. The object of the present invention is to develop a completely new chassis concept create with which generic transport systems can be equipped, paying particular attention to simple construction, easy assembly, good Maintenance properties and inexpensive manufacturing is laid. The chassis should lighter than conventional bogies and for high wheel loads with good Ground running property should be designed.
Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß der Fahrwerksrahmen zwischen den Radsätzen in zwei Hälften geteilt ist und jeder Radsatz in einer der Fahrwerksrahmenhälfte angeordnet ist, daß beide Fahrwerksrahmenhälften in der Fahrebene einstellgelenkig und in Fahrtrichtung zueinander begrenzt axialverschiebbar miteinander verbunden sind und daß zur zugfesten Kopplung der Wagenkästen eine die Einstellbarkeit der Fahrwerksrahmenhälften zulassende Koppelstange kardanisch beweglich zwischen den Wagenkästen angeordnet ist.To solve the problem, the invention proposes that the Undercarriage frame between the wheelsets is divided in half and each Wheelset is arranged in one of the chassis half that both Undercarriage frame halves in the driving level are adjustable and in the direction of travel limited to each other axially displaceably connected and that to tensile coupling of the car bodies an the adjustability of the Coupling rod that allows the chassis frame halves to move gimbally between the car bodies is arranged.
Das erfindungsgemäße Fahrwerk unterscheidet sich von den bisherigen Fahrwerkskonstruktionen vor allem durch den zweigeteilten torsions- und einstellgelenkigen Fahrwerksrahmen, der mit einfachen konstruktiven Mitteln eine große Beweglichkeit jedes einzelnen Radsatzes ermöglicht. Das Fahrwerk weist eine gute Kurvengängigkeit auf und ist durch die Zweiteilung der Fahrwerksrahmens besonders gut für die modernen untrennbaren Zugeinheiten geeignet.The chassis according to the invention differs from the previous ones Chassis constructions mainly through the two-part torsion and single-joint chassis frame, which with simple design means a allows great mobility of each individual wheel set. The chassis has one good cornering ability and is due to the division of the chassis frame particularly well suited for modern inseparable train units.
In einer besonders günstigen Ausgestaltung der Erfindung wird jede Fahrwerksrahmenhälfte im wesentlichen aus einem den Radsatz umgreifenden Gehäuse gebildet, in dem der Radsatz und ggf. das zugeordnete Radsatzgetriebe gelagert sind und an dem sich jeweils ein Wagenkasten der Zugeinheiten über hydraulische Federelemente abstützt.In a particularly favorable embodiment of the invention, each Half of the chassis frame essentially from a wheel set encompassing the wheelset Housing formed, in which the wheelset and, if applicable, the associated wheelset gear are stored and on each of which a car body of the train units supports hydraulic spring elements.
Durch Vereinigung der bisher einzelnen Bauteile wie Fahrwerksrahmen, Radsatzgehäuse und Getriebegehäuse in einen einzigen Gehäuse erhält dieses Mehrfachfunktion und ermöglicht die durch die Erfindung angestrebte Vereinfachung. Hydraulische Federelemente sind bekannt und werden vorzugsweise für Auto- und Mobilkrane eingesetzt. Sie eignen sich für das erfindungsgemäße Fahrwerk besonders gut, weil sie in der neuen Konzeption infolge ihres geringen Platzbedarfs leicht integriert werden können. Die Ausbildung des Fahrwerksrahmens aus den beiden zueinander einstellbaren Gehäusen ermöglicht die Lagerung des Radsatzes auf der Innenseite der Räder und gleichzeitig die Aufnahme des Radsatzgetriebes in einer sehr kompakten Baueinheit. By combining the previously individual components such as chassis frames, The wheelset housing and gear housing in a single housing receives this Multiple function and enables the simplification sought by the invention. Hydraulic spring elements are known and are preferred for auto and Mobile cranes used. They are particularly suitable for the chassis according to the invention good because in the new design they are light due to their small space requirement can be integrated. Forming the chassis frame from the two mutually adjustable housings allows the wheelset to be mounted on the Inside of the wheels and at the same time the inclusion of the wheelset gear in one very compact unit.

Das Drehgelenk ermöglicht sowohl eine Winkelbewegbarkeit der Gehäuse zueinander wie eine Verdrehung der Gehäuse gegeneinander, um eine gemeinsame in Fahrtrichtung liegende Achse. Die Bolzen-Bohrungsverbindung läßt auch eine begrenzte axiale Bewegung, mit der sich die Gehäuse im Fahrbetrieb voneinander weg oder aufeinander zu bewegen, zu.The swivel joint enables both angular movement of the housing relative to one another like twisting the case against each other to make a joint in Axis lying in the direction of travel. The bolt-hole connection also leaves one limited axial movement with which the housings differ from each other when driving to move away or towards each other.
Da die Drehgelenkverbindung der Gehäuse eine Zugkraftübertragung von einem Wagenkasten zum anderen nicht ermöglicht, ist nach einem weiteren Merkmal der Erfindung die Koppelstange vorgesehen, die die Wagenkästen der Zugeinheit beidseitig über Radial-Gelenklager verbindet und zwei in einer horizontalen Ebene voneinander beabstandete Holme aufweist, zwischen denen eine Quertraverse um ihre zur Koppelstangenlängsachse quer verlaufende Längsachse verschwenkbar angeordnet ist, in der zentral eine Führungsbohrung für den die Traverse senkrecht durchgreifenden verlängerten Drehgelenkzapfen des zwischen den Gehäusen vorgesehenen Drehgelenkes aufweist.Because the swivel connection of the housing transmits traction from one Another feature of the car body is not possible Invention provided the coupling rod that the car bodies of the train unit connects on both sides via radial spherical plain bearings and two in a horizontal plane has spaced-apart spars, between which a crossbar its longitudinal axis transverse to the longitudinal axis of the coupling rod can be pivoted is arranged in the center of a guide hole for the traverse perpendicular sweeping extended pivot pin of between the housings provided swivel.
Die erfindungsgemäße Koppelstange zwischen den Wagenkästen läßt Pufferstöße bis 200 t zu und verbindet die Wagenkästen der Zugeinheit. Die Ausbildung der Koppelstange mit den beiden Holmen und der Quertraverse zur Aufnahme des vertikalen Drehgelenkzapfens stellt sicher, daß sich die beiden Wagenkästen während der Fahrt vertikal gegeneinander bewegen können.The coupling rod according to the invention between the car bodies can buffer bumps 200 t and connects the car bodies of the train unit. Training the Coupling rod with the two spars and the crossbar to accommodate the vertical pivot pin ensures that the two car bodies during can move vertically against each other during the journey.
Zur Übertragung von Fahr- bzw. Bremskräften von den Radsätzen auf die Wagenkästen sind nach einem weiteren Merkmal der Erfindung zwischen den Wagenkästen und den Gehäuse der Fahrwerksrahmenhälften Druck- bzw. Zugstützen vorgesehen. For the transmission of driving or braking forces from the wheelsets to the Car bodies are according to another feature of the invention between the Car bodies and the housing of the chassis frame halves of pressure or tension supports intended.
Vorzugsweise und nach einem anderen Merkmal der Erfindung erfolgt der Antrieb der Radsätze über an mindestens einem Gehäuse seitlich angeflanschte Antriebsmotoren, deren Abtriebszapfen unmittelbar mit dem in dem Gehäuse gelagerten Radsatzgetriebe verbunden sind.Preferably and according to another feature of the invention, the drive of the Wheel sets via drive motors flanged to the side of at least one housing, whose output pin directly with that stored in the housing Wheelset transmissions are connected.
Als Antriebe können sowohl hydrostatische Antriebsmotoren vorgesehen sein, die als Fahr- und Bremsantrieb konzipiert sind, als auch Elektromotoren.Both hydrostatic drive motors can be provided as drives, which as Travel and brake drive are designed, as well as electric motors.
Obwohl die hydrostatischen Antriebsmotoren als Fahr- und Bremsantrieb konzipiert sind, ist es von Vorteil, für Not- oder Haltebremsen Scheibenbremsen vorzusehen, die an mindestens einem Rad des Radsatzes angreifen und am Gehäuse der jeweiligen Fahrwerksrahmenhälfte befestigt sind.Although the hydrostatic drive motors are designed as travel and brake drives are, it is advantageous to provide disc brakes for emergency or holding brakes engage at least one wheel of the wheel set and the housing of the respective Half of the chassis frame are attached.
Es hat sich gezeigt, das das beste Fahrverhalten des erfindungsgemäßen Fahrwerkes
erreichbar ist, wenn für die Länge der Koppelstange L die folgenden geometrischen
Bedingungen eingehalten werden:
- a =
- den Radsatzabstand im Fahrwerk und
- b =
- den Radsatzabstand im Wagenkasten
- a =
- the wheel set distance in the chassis and
- b =
- the distance between the wheelsets in the body
Mit dem erfindungsgemäßen Fahrwerk wird ein besonders einfaches Fahrwerk geschaffen, daß bei äußerst günstiger Kurvengängigkeit allen Erfordernissen moderner Transportsysteme Rechnung trägt. Das Fahrwerk ist preisgünstig herzustellen und ist verglichen mit Standard-Drehgestellen leichter. Die Vereinfachung und Gewichtsersparnis wird vor allem dadurch erreicht, daß viele Bauteile des erfindungsgemäßen Fahrwerkes Doppelfunktionen aufweisen, wie z.B. die Vereinigung von Getriebegehäuse und Fahrwerksrahmen. Die beiden Gehäuse der Fahrwerksrahmenhälften und somit die Getriebegehäuse, die gleichzeitig die Radsätze lagern, stützen sich direkt gegeneinander ab; Lenkeinrichtungen sind in der Koppelstange und in den Zug-Druckstützen vereinigt. Die Verwendung hydropneumatischer Federungen vereinfacht die Konstruktion; es wird ein sehr kompaktes Fahrwerk geschaffen, das im Wartungsfall leicht zu handhaben ist. The chassis according to the invention becomes a particularly simple chassis created that with extremely favorable cornering all requirements takes modern transport systems into account. The chassis is inexpensive and is lighter compared to standard bogies. The simplification and weight saving is achieved primarily by the fact that many components of the chassis according to the invention have double functions, such as the Union of gear housing and chassis frame. The two housings of the Chassis frame halves and thus the gearbox housing, which simultaneously the wheelsets store, support each other directly; Steering devices are in the Coupling rod and combined in the train-pressure supports. The usage hydropneumatic suspension simplifies the design; it will be a very compact chassis created, which is easy to handle in the event of maintenance.

seitliche Auslenkung der Koppelstange. Durch die Koppelung des Drehgelenks 11a,
11b mit der Traverse 15 vermittelt des Drehgelenkzapfens 12 werden die
Auslenkbewegungen der Koppelstange 8 zwangsläufig auf die Gehäuse 4a, 4b
übertragen, so daß sich die Radsätze 2a, 2b auf den jeweiligen Kurvenradius
einstellen. Für alle Kurvenradien gilt die Beziehung:
- a =
- den Radsatzabstand im Fahrwerk und
- b =
- den Radsatzabstand im Wagenkasten
- a =
- the wheel set distance in the chassis and
- b =
- the distance between the wheelsets in the body
