Description
Die Erfindung betrifft einen Krafteinleitungsknoten an einem als Hohlprofil ausgebildeten Rahmenabschnitt, der an einem Fahrerschutzdach eines Flurförderzeugs vorgesehen ist, das einen neigbaren Hubmast aufweist, wobei an dem Rahmenabschnitt ein mit dem Hubmast in Wirkverbindung stehender Neigezylinder befestigt ist.The invention relates to a force introduction node on a trained as a hollow profile frame portion which is provided on a driver's roof of a truck, which has a tiltable mast, wherein on the frame portion a standing with the mast in operative connection tilting cylinder is attached.
Gattungsgemäße Krafteinleitungsknoten sind am Fahrerschutzdach der Flurförderzeuge des Typs BR 392 der Anmelderin angeordnet und dienen jeweils der Befestigung eines Neigezylinders. Derartige Flurförderzeuge wurden vom Geschäftsbereich Material Handling der Anmelderin auf der Hannover-Messe 2002 erstmals der Öffentlichkeit präsentiert und werden seitdem in großen Stückzahlen hergestellt und verkauft.Generic force introduction nodes are arranged on the driver's roof of the forklift type BR 392 of the applicant and each serve to attach a tilting cylinder. Such material handling equipment was first presented to the public by the Applicant's Material Handling division at the Hannover Fair in 2002 and has since been produced and sold in large quantities.
Der aus dem Stand der Technik bekannte Krafteinleitungsknoten ist einstückig als Schmiedeteil ausgebildet, das an einem dafür vorgesehenen Rahmenabschnitt des Fahrerschutzdaches festgeschweißt wird.The known from the prior art force introduction node is integrally formed as a forged part, which is welded to a designated frame portion of the driver's roof.

Gegenstand der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Krafteinleitungsknoten der eingangs genannten Art zur Verfügung zu stellen, der eine einfachere und kostengünstigere Herstellung ermöglicht.The present invention is based on the object to provide a force introduction node of the type mentioned, which allows a simpler and more cost-effective production.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rahmenabschnitt zwei schalenförmige, durch Umformen hergestellte und miteinander verbundene Profilhälften und eine dazwischen angeordnete Versteifungsplatte aufweist und ein zur Verbindung mit dem Neigezylinder vorgesehener Befestigungsbolzen sich durch die Profilhälften und die Versteifungsplatte quer hindurch erstreckt.This object is achieved in that the frame portion has two shell-shaped, produced by forming and interconnected profile halves and a stiffening plate arranged therebetween and extending for connection to the tilting cylinder fastening bolt extends through the profile halves and the stiffening plate across.
Der erfindungswesentliche Gedanke besteht demnach darin, einen mehrteilig gefügten Knoten zu verwenden, der aus einfach und kostengünstig herstellbaren Umformteilen, nämlich den Profilhälften des Rahmenabschnitts und der Versteifungsplatte sowie aus einem simplen Drehteil, nämlich dem Befestigungsbolzen, besteht. Der erfindungsgemäße Krafteinleitungsknoten ist somit in den Rahmenabschnitt integriert. Es kommen dabei überwiegend Blechteile zum Einsatz. Dennoch kann durch die Formgebung der Profilhälften in Kombination mit dem Vorhandensein einer Versteifungsplatte ein hoher Verformungswiderstand des Krafteinleitungsknotens erzielt werden.The idea essential to the invention therefore consists of using a multi-part knot, which consists of simple and inexpensive to produce forming parts, namely the profile halves of the frame portion and the stiffening plate and a simple rotary member, namely the fastening bolt. The force introduction node according to the invention is thus integrated into the frame section. There are mainly sheet metal parts used. Nevertheless, the shaping of the profile halves in combination with the presence of a stiffening plate, a high deformation resistance of the force introduction node can be achieved.
Dadurch, dass zwischen den Profilhälften eine Versteifungsplatte angeordnet ist, durch die sich der Befestigungsbolzen quer hindurch erstreckt, wird einerseits die Steifigkeit des Krafteinleitungsknotens erhöht, andererseits lassen sich die beiden Profilhälften besser miteinander verbinden, insbesondere miteinander verschweißen.Characterized in that between the profile halves a stiffening plate is arranged, through which the fastening bolt extends transversely therethrough, on the one hand, the rigidity of the force introduction node is increased, on the other hand, the two profile halves can better connect together, in particular welded together.
In diesem Zusammenhang ist es auch günstig, wenn der Rahmenabschnitt an beiden Enden jeweils mittels einer mit den Profilhälften verbundenen Deckplatte abgeschlossen ist. Diese Maßnahme führt zu einer weiteren Erhöhung der Steifigkeit und erleichtert die Einbindung des Rahmenabschnitts in eine übergeordnete Rahmenstruktur.In this context, it is also advantageous if the frame section is closed at both ends in each case by means of a cover plate connected to the profile halves. This measure leads to a further increase in rigidity and facilitates the integration of the frame section into a superordinate frame structure.
Das Fahrerschutzdach weist bevorzugt zwei quer zum Flurförderzeug voneinander beabstandete Dachrohre auf, wobei jeweils im Übergangsbereich zwischen einem Dachbereich und einem heckseitigen Stützbereich des Dachrohres ein Rahmenabschnitt angeordnet ist.The driver's shelter roof preferably has two roof pipes spaced apart from one another perpendicular to the industrial truck, wherein a frame section is arranged in each case in the transition region between a roof area and a rear-side support area of the roof pipe.
Der Hubmast wird also durch zwei Neigezyilnder abgestützt, wobei die Neigezylinderkräfte von zwei erfindungsgemäßen Krafteinleitungsknoten aufgenommen und in das Fahrerschutzdach eingeleitet werden (Rahmenfunktion des Fahrerschutzdaches).The mast is thus supported by two tilting cylinders, wherein the tilting cylinder forces are absorbed by two force introduction nodes according to the invention and introduced into the driver's protection roof (frame function of the driver's protection roof).
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Konturen und/oder Querschnitte des Dachbereichs und des Stützbereichs des Dachrohres voneinander verschieden sind und im Rahmenabschnitt ineinander übergehen. Dadurch lässt sich auf einfache Weise das Fahrerschutzdach im Dach- und Stützbereich aus verschiedenen Profilrohren herstellen, wobei der Übergang zwischen den verschiedene Profilkonturen in die schalenförmigen Profilhälften des Krafteinleitungsknotens eingearbeitet ist.Another embodiment of the invention provides that the contours and / or cross sections of the roof area and the support area of the roof pipe are different from each other and merge into one another in the frame section. This makes it easy to produce the driver's roof in the roof and support area of different profile tubes, the transition between the different profile contours is incorporated into the cup-shaped profile halves of the force introduction node.
