Description

Die Erfindung betrifft die Befestigung von Aufnahmeelementen für Bauteile der Fahrwerkanlenkung, zu denen insbesondere Lenker und Anschläge gehören, an einer Bodengruppe eines aus Aluminium bestehenden Untergestelles eines Niederflur-Schienenfahrzeuges.The invention relates to the attachment of receiving elements for components of the suspension linkage, which include in particular handlebars and stops, on a floor assembly of an existing aluminum base of a low-floor rail vehicle.

Bei Niederflur-Schienenfahrzeugen ist wegen des niedrig angeordneten Fußbodens und damit auch des Untergestelles der Bauraum, der im Bereich des Fahrwerkes zur Verfügung steht, sehr gering. Dadurch ergibt sich insbesondere bei einer Ausführung des Untergestelles in Aluminiumtechnik ein Problem für die Befestigung von Bauteilen der Fahrwerkanlenkung, die aus Festigkeitsgründen häufig aus Stahl oder Stahlguss hergestellt sind. Außerdem ist es nicht immer möglich, diese Bauteile so zu befestigen, sie im Bedarfsfall leicht getauscht werden können, was aus Gründen der Reparaturfreundlichkeit an sich wünschenswert ist.In low-floor rail vehicles is due to the low floor and thus also the base of the space that is available in the chassis, very low. This results in particular in an embodiment of the undercarriage in aluminum technology, a problem for the attachment of components of the suspension linkage, which are often made of steel or cast steel for reasons of strength. In addition, it is not always possible to secure these components so they can be easily replaced if necessary, which is desirable for reasons of ease of repair in itself.

Bei bekannten Niederflur-Schienenfahrzeugen, insbesondere bei Straßenbahnfahrzeugen der Marke COMBINO, sind der Befestigung von Bauteilen der Fahrwerkanlenkung dienende Konsolen auf folgende Weise am Untergestell angebracht:

  • Das aus Aluminium hergestellte Untergestell hat eine Bodenplatte, die im Bereich der Fahrwerkkonsolen etwa 15 mm dick ist. Die Fahrwerkkonsolen bestehen aus Stahlguss und sind mittels Schließringbolzen an der Aluminiumbodenplatte befestigt, wobei die Köpfe der Schließringbolzen von der Oberseite dieser Bodenplatte her eingesetzt werden. Mit Rücksicht auf einen planen Fußboden, der üblicherweise mit einem Fußbodenbelag versehen ist, müssen die Schließringbolzen in die Aluminiumbodenplatte eingelassene Senkköpfe aufweisen. Dadurch ist ein Tausch der Fahrwerkkonsolen bei eventuellen Beschädigungen nur nach Entfernen von Innenausbauten des Fahrzeuges, speziell des Fußbodenbelages möglich, der alsdann ersetzt werden muss. Im Übrigen sind die durch die blechartige Aluminiumbodenplatte übertragbaren Kräfte relativ gering.
In known low-floor rail vehicles, in particular COMBINO brand tram vehicles, consoles attaching components of the chassis linkage are mounted on the undercarriage in the following manner:
  • The base made of aluminum has a base plate, which is about 15 mm thick in the area of the landing gear consoles. The chassis brackets are made of cast steel and are secured by means of lock bolts on the aluminum bottom plate, the heads of the lock bolts are used from the top of this base plate ago. With regard to a flat floor, which is usually provided with a floor covering, the lock bolts must be embedded in the aluminum floor plate Have countersunk heads. As a result, an exchange of the landing gear consoles in case of possible damage only after removal of interior fittings of the vehicle, especially the floor covering possible, which must then be replaced. Incidentally, the transferable through the sheet-like aluminum bottom plate forces are relatively low.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigung mit den gattungsgemäßen Merkmalen derart auszubilden, dass eine leichte Zugänglichkeit von außen gegeben ist und höhere Kräfte übertragen werden können.The invention has the object of providing a fastening with the generic features in such a way that easy accessibility is given from the outside and higher forces can be transmitted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an der Bodengruppe eine aus Aluminium hergestellte Grundplatte angeschweißt ist, die zumindest einen Einleger aus Stahl aufnimmt, wobei das Aufnahmeelement an diesem Einleger gehalten ist.This object is achieved in that on the floor assembly made of aluminum base plate is welded, which accommodates at least one insert made of steel, wherein the receiving element is held on this insert.

Die mit dem Gegenstand nach der Erfindung erzielbaren Vorteile bestehen insbesondere in der leichten Zugänglichkeit der Aufnahmeelemente (Konsolen) von außen und deren Austauschbarkeit, bei welcher der Innenausbau des Fahrzeuges nicht betroffen ist, sowie der Übertragbarkeit höherer Kräfte zwischen der Bodengruppe des Untergestelles und dem darunter angeordneten Fahrwerk.The achievable with the object according to the invention consist in particular in the easy accessibility of the receiving elements (consoles) from the outside and their interchangeability, in which the interior of the vehicle is not affected, and the transferability of higher forces between the bottom group of the undercarriage and the underlying Landing gear.
