Schwenkauslegerdrehgelenk am MastBoom swivel joint on the mast
Handelsübliche Schwenkauslegerdrehgelenke bestehen aus einem Gelenkbock und einem Drehgelenk, sind vornehmlich aus Aluminium gefertigt und haben kein Gleitlager und keine Welle. Die Drehachsen sind einfache Nietbolzen aus dem gleichen Material, aus dem auch die anderen Bauteile gefertigt sind (in Ausnahmefällen Nietbolzen aus nichtrostendem Stahl). Durch die Reibung zwischen den Materialien bei hohen Druckbeanspruchungen, wie sie auf diese Teile vorkommen, wird die Beweglichkeit der Schwenkausleger gegenüber der Kettenwerkswanderung ungemein erschwert. Besonders bei Auslegern in starken Innenbögen ist eine reibungslose Regulierung der Fahrleitung durch das Kettenwerk nicht gegeben.Commercially available swivel boom swivel joints consist of a swivel bracket and a swivel joint, are primarily made of aluminum and have no plain bearings or shaft. The swivel axes are simple rivet bolts made of the same material as the other components (in exceptional cases, rivet bolts made of stainless steel). The friction between the materials under high pressure loads, such as those that occur on these parts, makes the mobility of the swivel boom extremely difficult compared to the movement of the catenary. Particularly with booms in strong inner curves, the catenary cannot regulate the overhead line smoothly.
Um zu erreichen, daß das Kettenwerk ohne die Beeinflussung durch Reibung wirklich von Anfang bis Ende die Fahrleitung reguliert, werden die Schwenkauslegerdrehgelenke mit Lagerbuchsen aus selbstschmierendem seewasserfestem Sinterlagermaterial und einer entsprechenden Welle aus Edelstahl ausgestattet (Schutzansprüche 1 - 3).In order to ensure that the catenary really regulates the overhead line from start to finish without being influenced by friction, the swivel boom joints are equipped with bearing bushes made of self-lubricating, seawater-resistant sintered bearing material and a corresponding shaft made of stainless steel (protection claims 1 - 3).
Durch das Gleitlager bleibt bei Druckbeanspruchung des Auslegerrohres die Gewährleistung erhalten, daß das Auslegerrohr der Kettenwerkslängendehnung mit geringstem Kraftaufwand nachfolgt. Somit können die Nachspannvorrichtungen kontinuierlich arbeiten und benötigen keine großen Kraftdifferenzen zum Einsetzen der Regulierungsarbeit.The sliding bearing ensures that when the boom tube is subjected to pressure, the boom tube follows the lengthening of the chain system with the least amount of force. This means that the tensioning devices can work continuously and do not require large differences in force to start the adjustment work.
Diese Erfindung wurde bereits Mitte 1995 beim Neubau der Linie B der Mannheimer Verkehrsgesellschaft (MVG) in Mannheim verwendet und ist seitdem auf Interesse bei anderen Verkehrsbetrieben gestoßen.This invention was already used in mid-1995 in the new construction of Line B of the Mannheimer Verkehrsgesellschaft (MVG) in Mannheim and has since attracted interest from other transport companies.

Die Ausführung des Schwenkauslegerdrehgelenkes ist in nachfolgenden Zeichnungen dargestellt.The design of the swivel boom joint is shown in the following drawings.
Zeichnung 1 zeigt einen handelsüblichen Gelenkbock und Zeichnung 2 ein handelsübliches Drehgelenk mit Gabel.Drawing 1 shows a commercially available swivel bracket and drawing 2 shows a commercially available swivel joint with fork.
Die Zeichnungen 3 und 4 zeigen, wie die Lagerbuchsen (5) und die Welle (4) in das Schwenkauslegerdrehgelenk, bestehend aus Gelenkbock (1) und Drehgelenk (6) integriert werden. Gegen ein Herausfallen ist die Welle (4) oben durch eine angeschweißte (2) nichtrostende Scheibe (3) und unten durch einen Splint (7) gesichert.Drawings 3 and 4 show how the bearing bushes (5) and the shaft (4) are integrated into the swivel boom swivel joint, consisting of the swivel bracket (1) and swivel joint (6). The shaft (4) is secured against falling out at the top by a welded (2) stainless steel disc (3) and at the bottom by a split pin (7).
