Abstract

The running gear has a secondary suspension stage with hydro-pneumatic springs (1), which are mounted on a pivoting support and are guided along a curved path, which is especially a circular arc (3). The support has a cradle (2) with a roller bearing. The centre of the path is coincident with the vertical axis of a spigot (6), around which the running gear can rotate with respect to the vehicle. The springs and their support are connected at the top to the cradle, and at the bottom to brackets (4) on a longitudinal beam (5) on the running gear.

Description

Die Erfindung befaßt sich mit einem Fahrwerk für Schienenfahrzeuge, insbesondere für Niederflur-Schienenfahrzeuge.The invention relates to a chassis for rail vehicles, especially for low-floor rail vehicles.

Bei Schienenfahrzeugen, speziell bei Niederflur-Schienenfahrzeugen, ist die Bauhöhe der Fahrwerke oftmals so stark eingeengt, daß kein Bauraum für eine Wiege, die eine Drehbewegung um die senkrechte Achse des Fahrwerkes während der Fahrt im Gleisbogen ermöglicht und die Stützkraft von den seitlich außen liegenden Federn zum mittig angeordneten Drehzapfen überträgt, vorhanden ist.For rail vehicles, especially low-floor rail vehicles, the overall height is Trolleys are often so tight that there is no space for a cradle that rotates around the vertical axis of the Chassis while driving in the curve and allows Support force from the springs on the outside to the center arranged pivot transmits, is present.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Fahrwerk für Schienenfahrzeuge zu schaffen, bei welcher das vorstehend genannte Problem vermieden wird.Of the The invention is therefore based on the object of a chassis To create rail vehicles in which the above mentioned problem is avoided.

Die Erfindung erreicht dieses Ziel durch den Gegenstand des Anspruchs 1. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.The invention achieves this goal through the subject of Claim 1. Advantageous further developments are See subclaims.

Die Erfindung schafft in vorteilhafter Weise ein Fahrwerk mit weit außenliegenden hydro-pneumatischen Federn mit Pendelstütze, welche keinen Bauraum über dem längsliegenden Fahrwerksrahmen für die Anlenkungs- und Übertragungsglieder benötigen.The invention advantageously creates a chassis with hydro-pneumatic springs on the outside Pendulum support, which has no space above the longitudinal one  Chassis frame for the linkage and transmission links need.

Der Fahrwerkslängsträger weist erfindungsgemäß außen seitlich angeordnete Konsolen auf, auf denen sich unten die Lager- und Abrollfläche der Pendelstütze befindet. Oberhalb der hydro-pneumatischen Federn befindet sich ein walzgelagerter Schlitten, der auf einem Abschnitt einer Kreisbahn um den Mittelpunkt der senkrechten Drehachse im Fahrzeug gleitet. Der Schlitten wird mit einem Gestänge oder ähnlich wirkenden Bauelementen vom Fahrwerksrahmen geführt, so daß die hydro-pneumatischen Federn mit Pendelstütze immer senkrecht stehen, seitlich aber ausschwenken können. Die Anordnung erfordert keine besonderen Ausführungsformen des Fahrwerkes. Dies kann sowohl einachsig als auch mehrachsig sein. Ebenso kann der Drehzapfen am Fahrwerk über eine Lenkerstange oder Lemniskatenlenker angekoppelt werden.According to the invention, the longitudinal chassis beam has a side on the outside arranged consoles on which the storage and Rolling surface of the pendulum support is located. Above the hydro-pneumatic springs there is a roller bearing Sled running on a section of a circular path around the The center of the vertical axis of rotation in the vehicle slides. Of the Sledge is used with a linkage or something similar Components guided by the chassis frame, so that the hydro-pneumatic springs with pendulum support always vertical stand, but can swing out sideways. The order does not require any special embodiments of the chassis. This can be both uniaxial and multiaxial. As well can the pivot on the chassis via a handlebar or Lemniscate handlebars are coupled.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel erläutert, wobei auch Vorteile und Optionen der Erfindung deutlich werden. Begriffe wie "oben", "unten" usw. beziehen sich auf Schienenfahrzeuge in ihrer gewöhnlichen Stellung und sind nicht einschränkend zu verstehen. Es zeigtThe invention is described below using an exemplary embodiment explained, with advantages and options of Invention become clear. Terms like "top", "bottom" etc. refer to rail vehicles in their ordinary Position and are not to be understood as restrictive. It shows

Fig. 1 einen Querschnitt eines Abschnittes eines erfindungsgemäß ausgebildeten Fahrwerkes eines Niederflur-Schienenfahrzeugs; Figure 1 shows a cross section of a portion of a chassis designed according to the invention of a low-floor rail vehicle.

Fig. 2 die Draufsicht im Schnitt I-I aus Fig. 1. Fig. 2 is a plan view in section II in FIG. 1.

Die Fig. 1 und 2 zeigen eine hydro-pneumatische Feder 1 mit Pendelstütze, die oben einen wälzgelagerten Schlitten 2 trägt. Dieser rollt auf einem Abschnitt einer Kreisbahn 3. Die Pendelstütze der hydro-pneumatischen Feder 1 ist unten auf einer Konsole 4 gelagert, die am Fahrwerkslängsträger 5 angeschlossen ist. Figs. 1 and 2 show a hydro-pneumatic spring 1 with pendulum support which carries a rolling bearing-mounted carriage 2 above. This rolls on a section of a circular path 3 . The pendulum support of the hydro-pneumatic spring 1 is mounted below on a bracket 4 , which is connected to the chassis side member 5 .

Der Abschnitt der Kreisbahn 3 hat seinen Mittelpunkt auf der senkrechten Achse des Drehzapfens 6. Dieser ist durch z. B. Lemniskatenlenker 7 mit dem Fahrwerksquerträger 8 verbunden. Der wälzgelagerte Schlitten 2 wird durch ein mit ihm verbundenes Gestänge 9, welches wiederum an einem Arm 10, der am Fahrwerkslängsträger 5 befestigt ist, bei Winkelausschlägen des Fahrwerkes so geführt, daß die hydro-pneumatische Feder 1 in der Seitenansicht des Fahrzeugs immer senkrecht steht.The section of the circular path 3 has its center on the vertical axis of the pivot pin 6 . This is by z. B. Lemniscat link 7 connected to the chassis cross member 8 . The roller-mounted carriage 2 is guided by a linkage 9 connected to it , which in turn is guided on an arm 10 which is fastened to the chassis longitudinal member 5 at angular deflections of the chassis so that the hydro-pneumatic spring 1 is always vertical in the side view of the vehicle.
