Abstract
Description
Die Erfindung betrifft ein Flurförderzeug mit einem Fahrzeugrahmen, an dem eine Antriebsachse befestigt ist.The Invention relates to an industrial truck with a vehicle frame to which a drive axle is attached.
Ein
gattungsgemäßes Flurförderzeug
ist in der
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Flurförderzeug der eingangs genannten Art zur Verfügung zu stellen, das eine vereinfachte Befestigung der Antriebsachse aufweist und eine Körperschallabkopplung ermöglicht.Of the The present invention is based on the object, an industrial truck of the type mentioned above to provide a simplified Attachment of the drive axle has and a structure-borne noise decoupling allows.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Fahrzeugrahmen im Vorderbereich mindestens zwei parallele, stangenförmige Querstreben aufweist, an denen die Antriebsachse befestigt ist.These Task is inventively characterized solved, that the vehicle frame in the front region at least two parallel, rod-shaped cross struts has, to which the drive axle is attached.
Erfindungswesentlich ist demnach der Aufbau des Fahrzeugrahmens mit mindestens zwei stangenförmigen Querstreben, die neben der Funktion als frontseitige Querverbindungsteile des Fahrzeugrahmens zugleich als Lagerung für die Antriebsachse dienen. Die Ausbildung der Querstreben als Stangen ist günstig im Hinblick auf einen einfachen, kostengünstigen und platzsparenden Aufbau, wobei gleichzeitig große Kräfte (z. B. Achslasten, Kräfte aus Antriebs- und Bremsmomenten) aufgenommen werden können.essential to the invention is therefore the structure of the vehicle frame with at least two rod-shaped cross struts, in addition to the function as front cross-connecting parts of Vehicle frame also serve as storage for the drive axle. The formation of the cross struts as rods is favorable in terms of a simple, inexpensive and space-saving design, at the same time large forces (z. B. axle loads, forces from drive and braking torques) can be recorded.
Im Hinblick auf eine funktionssichere und leicht zu montierende Befestigung der Antriebsachse an den Querstreben ist es günstig, wenn die Querstreben an beiden Enden in Traglaschen gehaltert sind, die an einem Achsgehäuse der Antriebsachse befestigt sind.in the Regard to a functionally reliable and easy to mount attachment the drive axle on the cross braces, it is advantageous if the cross braces are supported at both ends in support plates, which on an axle housing of the Drive axle are attached.
Sofern die Traglaschen einstückig an dem Achsgehäuse angeformt sind, ergibt sich eine weitere Vereinfachung. Die Traglaschen können dabei zusammen mit dem Achsgehäuse durch Gießen hergestellt werden.Provided the support straps in one piece on the axle housing are formed, there is a further simplification. The carrying straps can along with the axle housing by pouring getting produced.
Es erweist sich als günstig, wenn der Fahrzeugrahmen zwei seitlich voneinander beabstandete Längsträger aufweist, die jeweils mit Aufnahmeschlitzen für Endabschnitte der Querstreben versehen sind. Die Querstreben können dann im bereits an der Antriebsachse vormontierten Zustand, also zusammen mit der Antriebsachse in die Aufnahmeschlitze des Fahrzeugrahmens eingehängt und dort verankert werden.It turns out to be cheap if the vehicle frame has two laterally spaced side members, each with receiving slots for end portions of the cross braces are provided. The cross struts can then in the already pre-assembled on the drive axle state, ie together with the drive axle in the receiving slots of the vehicle frame hooked and anchored there.
Hierbei ist eine Ausgestaltung zweckmäßig, wonach die Querstreben in den Längsschlitzen formschlüssig verriegelbar sind.in this connection is an embodiment appropriate, according to which the cross struts in the longitudinal slots form-fitting are lockable.
Gemäß einer nicht minder günstigen Ausgestaltung der Erfindung wird vorgeschlagen, dass der Fahrzeugrahmen zwei seitlich voneinander beabstandete Längsträger aufweist, die jeweils mit den Querstreben fest verbunden, insbesondere verschweißt sind. Dadurch wird ein sehr stabiler Fahrzeugrahmen geschaffen, an dessen vorderen, die Querstreben enthaltenden Bereich die Antriebsachse befestigt wird.According to one no less favorable Embodiment of the invention, it is proposed that the vehicle frame has two laterally spaced apart side members, each with firmly connected to the cross braces, in particular welded. This creates a very stable vehicle frame, on whose front, the transverse struts containing area attached to the drive axle becomes.
Hierbei erweist es sich von Vorteil, wenn das Achsgehäuse mittels seitlich voneinander beabstandeter, teilbarer Traglaschen an den Querstreben gehaltert ist.in this connection it proves advantageous if the axle housing by means of laterally from each other spaced, separable support tabs supported on the crossbars is.
Zur Verringerung des Körperschalldurchgangs sind in Weiterbildung der Erfindung die Querstreben in den Bereichen der Befestigung der Antriebsachse mit elastischen Abkopplungsbuchsen versehen. Die beispielsweise aus Kunststoff bestehenden Abkopplungsbuchsen dienen als geräuschdämpfende Elemente, die eine Übertragung von Körperschall vermindern.to Reduction of structure-borne sound passage are in development of the invention, the cross braces in the areas the attachment of the drive axle provided with elastic decoupling sockets. The existing example of plastic decoupling sockets serve as noise dampening Elements that are a transmission of structure-borne noise Reduce.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung kann mindestens eine Abkopplungsbuchse einen in Querrichtung wirksamen Anschlag aufweisen. Gesonderte Queranschläge sind daher nicht erforderlich.According to one advantageous embodiment of the invention can be at least one decoupling socket have a transversely effective stop. Separate transverse stops are therefore not required.
Die Längsträger können im Bereich der Befestigung der Querstreben jeweils als Radkastenwand ausgebildet sein.The Side members can in Area of attachment of the cross braces in each case as a wheel well wall be educated.
Besonders vorteilhaft ist eine Weiterbildung der Erfindung, gemäß der die Querstreben in Fahrzeuglängsrichtung voneinander beabstandet sind und an der vorderen Querstrebe ein Hubgerüst neigbar gelagert ist. Die vordere Querstrebe übernimmt somit neben der Funktion als Teil des Fahrzeugrahmens und der Funktion als Befestigungselement für die Antriebsachse noch eine Trag- und Neigelagerfunktion für das Hubgerüst.Especially advantageous is a development of the invention, according to the Cross struts in the vehicle longitudinal direction spaced apart and at the front cross member a mast tiltable is stored. The front cross strut thus takes over the function as part of the vehicle frame and the function as a fastener for the Drive axle still a supporting and tilting bearing function for the mast.
