Der Fahrzeugkasten ist über eine Federung direkt auf dem Fahrwerk abgestützt. Die Masse des Fahrwerks ist beträchtlich reduziert, da ein Rahmen fehlt. Ein Paar von Triebradsätzen wird durch zwei Motoren angetrieben, die mittels Tatzlagern auf den Radachsen angebracht sind ("Tatzlagerantrieb"). Bei stossartigen Beschleunigungen - vor allem vertikal und quer zum Fahrzeug - wirken die Massen der Radsätze, der Motoren sowie jene der Getriebe und Bremseinheiten zusammen als gemeinsame Masse, die an das übrige Fahrzeug über die Federung gekoppelt ist. Die Trägheitskraft dieser gemeinsamen Masse hat eine entsprechende Reaktion der Schienen und der Gleisanlage zur Folge, die mit Verschleisswirkungen verbunden ist. Zur Schonung der Gleisanlage ist es erforderlich, dass stossartige Einwirkungen durch Trägheitskräfte möglichst klein ausfallen. Umgekehrt haben schlechte Gleise auch einen schädigenden Effekt auf Komponenten von Tatzlagerantrieben.The vehicle body is suspended directly on the chassis supported. The mass of the undercarriage is considerably reduced since one Frame is missing. A pair of drive wheel sets is powered by two motors driven, which are attached to the wheel axles by means of paw bearings ("Tatzlagerantrieb").

Die Motoren sind jeweils über ein Getriebe und elastische Elemente, die eine Hohlwelle umfassen, mit dem zugeordneten Radsatz verbunden. Sie sind über weitere elastische Elemente am Fahrzeugkasten befestigt. Das Fahrwerk kann mit einer gleisschonenden Einrichtung zur Radialeinstellung der Radsätze ausgebildet sein.The drive unit has a chassis that frameless one Carries the vehicle body.

Der in Fig. 1 dargestellte GTW 1 umfasst eine zentrale Antriebseinheit 10, die
beidseitig über Gelenke 11 mit den für einen Fahrgasttransport vorgesehenen
Fahrzeugteilen 12 und 13 (mit Lauffahrwerken 14) verbunden ist. Die
Antriebseinheit 10 besteht aus einem Fahrzeugkasten 10' und einem
antreibbaren Fahrwerk 3, das über eine Federung 9 mit dem Fahrzeugkasten
10' verbunden ist und dessen Räder 31 auf Schienen 2 bewegbar sind.The GTW 1 shown in FIG. 1 comprises a central drive unit 10 which
on both sides via joints 11 with those provided for passenger
Das Fahrwerk 3 der Figuren 2 und 3 umfasst zwei Radsätze 30, die jeweils
über einen Motor 5 und ein Getriebe 6 antreibbar sind. Die Radsätze 30 sind
über ein Paar von Achsanlenkungen 4 gekoppelt, mit denen sie selbsttätig
radial bezüglich einer zu durchlaufenden Kurve einstellbar sind. Jede
Achsanlenkung 4 umfasst zwei Stangen 40a und 40b, die gelenkig über einen
kurzen Hebel 41 miteinander verbunden sind und die jeweils an
entsprechendenden Achslagergehäusen 36a und 36b gelenkig gelagert
(Lager 37) sind. Die Hebel 41 der beiden Achsanlenkungen 4 sind um
Koppellager 42 schwenkbar, die über eine Koppelwelle 43 in Verbindung
stehen können. In einer anderen Ausführungsform der Achsanlenkungen 4
können die Achslagergehäuse 36a und 36b mit den zugeordneten Stangen
40a bzw. 40b starr verbunden sein.The
Von der Federung 9 sind lediglich zwei Schraubenfedern 90 eines Rads 31
gezeichnet. Zwischen diesen beiden Schraubenfedern 90 ist jeweils ein
schräg stehender Vertikaldämpfer 91 angeordnet, der wie die
Schraubenfedern 90 am nicht dargestellten Fahrzeugkasten 10' befestigt ist.
Die Motoren 5 und Getriebe 6 sind über Pendel 8 (Pendelstange 80, elastisch
ausgebildetes Sphärolager 81) ebenfalls am Fahrzeugkasten 10' befestigt.Only two
Erfindungsgemäss sind die Motoren 5 jeweils über die Getriebe 6 und
elastische Elemente, die eine Hohlwelle 33 umfassen, mit dem zugeordneten
Radsatz 30 verbunden und über weitere elastische Elemente 81 am
Fahrzeugkasten 10' befestigt. (Ein Antrieb für einen Radsatz mit Hohlwelle
und elastischen Verbindungselementen ist in der EP-A 0 534 899 (= p.6453)
beschrieben.) Die Achsanlenkungen 4 stellen einen Kraftschluss zwischen
Radachsen 32 und dem Fahrzeugkasten 10' her, wobei dieser Kraftschluss
über elastische Elemente, nämlich elastisch ausgebildete Koppellager 42,
geführt wird. Durch die Gesamtheit der elastisch und nachgiebig
ausgebildeten Verbindungen zwischen den Radsätzen 30, den Motoren 5 und
dem Fahrzeugkasten 10' ergibt sich ein Fahrwerk 3 mit vollabgefedertem
Antrieb, das die hinsichtlich stossartigen Beschleunigungen geforderten
Bedingungen erfüllt.According to the invention, the
Eine weitere wichtige Komponente eines Fahrwerks 3, nämlich eine Bremse
7, ist in Fig. 4 gezeigt (Bremszylinder 70, Hebel 71 mit Bremsbacken 72). Sie
ist am Motor 5 befestigt und ist somit auch bezüglich dem Radsatz 30
abgefedert. In Fig. 4 ist auch die federnde Verbindung zwischen dem
Getriebe 6 und der Radachse 32 dargestellt. Diese ist durch die Hohlwelle 33
und zwei elastische Verbindungsteile 34 und 35 gegeben. Das Teil 34
verbindet die Hohlwelle 33 elastisch mit der Radachse 32, während das Teil
35 eine elastische Verbindung zwischen der Hohlwelle 33 und dem Getriebe
6 bildet. Strichpunktiert ist eine Bremsscheibe 37 angedeutet, die alternativ
zur Bremse 7 vorgesehen sein kann. Bei einer solchen Scheibenbremse sind
die aktivierbaren Komponenten am Fahrzeugkasten angebracht.Another important component of a
Fig. 5 zeigt ein Fahrwerk 3, dessen beiden Motoren 5 zentral über einen
Anlenkpunkt 55 derart gekoppelt sind, dass für die gekoppelten Motoren 5
eine rotatorische Pendelbewegung (Pfeile 55') um eine vertikale Zentralachse
in z-Richtung durch den Anlenkpunkt 55 möglich ist. Fig. 5 shows a
Fig. 6 zeigt ein Fahrwerk 3, dessen beiden Motoren 5 einschliesslich der
zugeordneten Getriebe 6 an zwei Stellen 56a und 56b so gekoppelt sind,
dass eine Pendelbewegung in y-Richtung (Pfeil 56'), d. h. in Richtung der
Radachsen 32, möglich ist. Die Motoren 5 können über Parallelpendel starr
gekoppelt sein, so dass die Bewegungen nur in y-Richtung frei sind. Die
Koppelung kann auch weich sein, so dass sich neben translatorischen
zusätzlich rotatorische Pendelbewegungen ergeben können. Ein weitere
Möglichkeit ist, dass die Motoren 5 in der x-y-Ebene starr gekoppelt sind und
über zwei parallele Pendel 8 am Fahrzeugkasten 10' angebracht sind, wobei
die Pendelstangen 80 an deren beiden Enden Sphärolager 81 als
Verbindungselemente aufweisen. In diesem Fall sind Bewegungen in y-Richtung
und um die vertikale Zentralachse wie beim Ausführungsbeispiel der
Fig. 5 möglich.Fig. 6 shows a
