Abstract
Es wird eine Tandemachse einer mobilen Arbeitsmaschine mit einer arbeitsmaschinenseitig befestigten Achsbrücke vorgeschlagen, wobei die Enden der Achsbrücke (1) jeweils an einem Antriebskasten (2, 3) drehbar über eine zugeordnete Lageranordnung gelagert sind, und wobei als Lageranordnung eine Gleitlagerung mit einem Außenring (4) und einem Innenring (5) vorgesehen ist.It is proposed a tandem axle of a mobile machine with a working machine side fixed axle, wherein the ends of the axle (1) are each mounted on a drive box (2, 3) rotatably via an associated bearing assembly, and wherein as a bearing assembly a slide bearing with an outer ring (4 ) and an inner ring (5) is provided.
Description
Die vorliegende Erfindung betrifft eine Tandemachse einer mobilen Arbeitsmaschine mit einer arbeitsmaschinenseitig befestigten Achsbrücke gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. The present invention relates to a tandem axle of a mobile machine with a working machine side mounted axle bridge according to the closer defined in the preamble of
Mobile Arbeitsmaschinen mit einer Tandemachse sind aus der Fahrzeugtechnik hinreichend bekannt. Die Tandemachse umfasst eine arbeitsmaschinenseitig befestigte Achsbrücke, deren Enden an einem Antriebskasten drehbar jeweils über eine Lageranordnung gelagert sind. Die Antriebskästen umfassen eine Antriebsübertragung für die zwei vorgesehenen Antriebsrädern, die von der Achsbrücke über die in den Antriebskästen vorgesehene Antriebsübertragung angetrieben werden. Um eine Fahrt der mobilen Arbeitsmaschine über Unebenheiten zu ermöglichen, ist vorgesehen, dass die Antriebskästen mit den Antriebsrädern zum Beispiel über eine Vierpunktlagerung drehbar bzw. schwenkbar an der Achsbrücke gelagert sind. Bei der vorgesehenen Vierpunktlagerung ergibt sich der Nachteil, dass ein kostenintensives Spezialfett manuell in das Lager eingebracht werden muss. Dies ist nicht nur arbeitsaufwändig, sondern beeinflusst auch die Lebensdauer der Tandemachse nachteilig. Mobile machines with a tandem axle are well known in the automotive industry. The tandem axle comprises a working machine side mounted axle bridge whose ends are rotatably mounted on a drive box each via a bearing assembly. The drive boxes comprise a drive transmission for the two intended drive wheels which are driven by the axle bridge via the drive transmission provided in the drive boxes. In order to enable a ride of the mobile machine over bumps, it is provided that the drive boxes are rotatably mounted with the drive wheels, for example via a four-point bearing or pivotally mounted on the axle bridge. In the proposed four-point storage results in the disadvantage that a costly special grease must be manually introduced into the camp. This is not only labor intensive, but also adversely affects the life of the tandem axle.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Tandemachse der eingangs beschriebenen Gattung vorzuschlagen, bei der eine kostengünstige und wartungsfreie Lageranordnung vorgesehen ist. The present invention is based on the object to propose a tandem axle of the type described above, in which a cost-effective and maintenance-free bearing assembly is provided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst, wobei sich vorteilhafte Ausgestaltungen aus den Unteransprüchen und der Beschreibung sowie den Zeichnungen ergeben. This object is achieved by the features of
Somit wird eine Tandemachse einer mobilen Arbeitsmaschine oder dergleichen mit einer arbeitsmaschinenseitig befestigbaren Achsbrücke vorgeschlagen, wobei die Enden der Achsbrücke jeweils an einem zugeordneten Antriebskasten drehbar jeweils um eine Lageranordnung gelagert sind. Um eine wartungsfreie und kostengünstige Lagerung bei der Tandemachse vorzusehen, ist erfindungsgemäß als Lageranordnung eine Gleitlagerung mit nur einem Außenring und nur einem Innenring vorgesehen. Thus, a tandem axle of a mobile work machine or the like is proposed with a working machine side attachable axle bridge, wherein the ends of the axle bridge are each mounted on an associated drive box rotatably about a bearing assembly. In order to provide a maintenance-free and cost-effective storage in the tandem axle, a slide bearing with only one outer ring and only one inner ring is provided according to the invention as a bearing assembly.
Auf diese Weise wird eine kostengünstige ohne Spezialschmiermittel funktionierende Lagerlösung bei der Tandemachse der Arbeitsmaschine realisiert. Die vorgesehene Gleitlagerung kann zum Beispiel eine kompakt aufgebaute Gleitlagerung zum Beispiel aus Buntmetall-Scheiben und Buchsen oder dergleichen als Gleitlagerbereiche umfassen. Dadurch, dass nur ein Außenring und ein Innenring vorgesehen sind, wird die Anzahl der erforderlichen Bauteile gegenüber bekannten Lösungen deutlich verringert. Hierdurch steht mehr Bauraum zur Verfügung und die beiden vorgesehenen Bauteile können massiver ausgeführt werden, so dass die Steifigkeit der Lageanordnung und damit der Tandemachse erhöht wird. In this way, a cost effective without special lubricants bearing solution is realized in the tandem axis of the machine. The proposed sliding bearing may comprise, for example, a compact sliding bearing, for example made of non-ferrous metal discs and bushes or the like as plain bearing areas. The fact that only an outer ring and an inner ring are provided, the number of required components compared to known solutions is significantly reduced. As a result, more space is available and the two components provided can be made more massive, so that the rigidity of the bearing arrangement and thus the tandem axle is increased.
Die erfindungsgemäße Tandemachse kann bevorzugt bei einem Grader als mobile Arbeitsmaschine eingesetzt werden. Andere Anwendungsmöglichkeiten bei konstruktiv ähnlich aufgebauten Arbeitsmaschinen sind auch denkbar. The tandem axle according to the invention can preferably be used in a grader as a mobile work machine. Other applications in structurally similar machines are also conceivable.
Nachfolgend wird die vorliegende Erfindung anhand der Zeichnungen weiter erläutert. Es zeigen: Hereinafter, the present invention will be further explained with reference to the drawings. Show it:
