Description

Achsbrücke für eine angetriebene Kraftfahrzeuqachse  Axle bridge for a powered motor vehicle axle
Die Erfindung betrifft eine Achsbrücke für eine angetriebene Kraftfahrzeugachse gemäß dem Patentanspruch 1. The invention relates to an axle bridge for a driven motor vehicle axle according to claim 1.
Eine gattungsgemäße Achsbrücke ist beispielsweise aus der DE2006 012 342 A1 bekannt. Die Offenlegungsschrift offenbart eine Achsbrücke welche mit einer Differentiallageranordnung verbunden ist. Die Differentiallageranordnung umfasst einen Befestigungskranz der sich an der Achsbrücke anlegt und ist mit Hilfe mehrerer Befestigungsbolzen an der Achsbrücke festgelegt. A generic axle bridge is known for example from DE2006 012 342 A1. The published patent publication discloses an axle bridge which is connected to a differential bearing arrangement. The differential bearing arrangement comprises a fastening ring which rests against the axle bridge and is fixed to the axle bridge with the aid of a plurality of fastening bolts.
Des Weiteren umfasst die Differentiallageranordnung ein erstes und ein zweites Befestigungselement welche zumindest mittelbar über ein erstes und ein zweites Differentiallager einen Differentialkorb aufnehmen und radial sowie axial abstützen. Furthermore, the differential bearing arrangement comprises a first and a second fastening element which receive at least indirectly via a first and a second differential bearing a differential carrier and supported radially and axially.
Der Differentialkorb ist im Inneren des Achsbrückeninnenraumes der Achsbrücke angeordnet. Die Befestigungselemente der Differentiallageranordnung stützen sich an den Anlageabschnitten, welche innerhalb des Achsbrückeninnenraumes angeordnet sind, ab. Das verhindert ein Aufbiegen und damit eine Veränderung der Lagereinstellung und der Last. The differential cage is arranged inside the Achsbrückeninnenraumes the axle bridge. The fasteners of the differential bearing assembly are based on the abutment sections, which are arranged within the Achsbrückeninnenraumes from. This prevents a bending and thus a change in the bearing adjustment and the load.
Bei den bekannten Achsbrücken besteht regelmäßig das Problem, dass die Differentialanordnung nur in einer festgelegten Position an die Achsbrücke montiert werden kann. Sollte eine abweichende Montageposition gefordert sein, so müssen die beiden Befestigungselemente der Differentiallageranordnung gleich groß ausgeführt werden damit die Differentiallageranordnung gedreht verbaut werden kann. Dies hat wiederrum den Nachteil, dass die Befestigungselemente bezogen auf den Anlagedurchmesser identisch zumindest gleich groß ausgeführt werden müssen. In the known Achsbrücken there is regularly the problem that the differential assembly can be mounted only in a fixed position to the axle bridge. If a different mounting position be required, so the two fasteners of the differential bearing assembly must be made the same size so that the differential bearing assembly can be installed rotated. This in turn has the disadvantage that the fastening elements have to be identical in terms of the plant diameter at least the same size.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Achsbrücke anzugeben, welche die Nachteile des Standes der Technik überwindet. The object of the present invention is therefore to provide an axle bridge, which overcomes the disadvantages of the prior art.
Diese Aufgabe wird gemäß dem kennzeichnenden Merkmal des Patentanspruchs 1 dadurch gelöst, dass die Anlageabschnitte der Achsbrücke derart ausgeführt sind, dass die Differentiallageranordnung in wenigstens zwei unterschiedlichen Montagepositionen montierbar ist. This object is achieved according to the characterizing feature of claim 1, characterized in that the abutment sections of the axle bridge are designed such in that the differential bearing arrangement can be mounted in at least two different mounting positions.
Weitere vorteilhafte Ausführungsvarianten sind in den Figuren sowie in den abhängigen Ansprüchen angegeben. Further advantageous embodiments are given in the figures and in the dependent claims.
Gemäß einer vorteilhaften Ausführungsvariante können sich die Montagepositionen der Differentiallageranordnung dadurch unterscheiden, dass eine zweite Montageposition bezogen auf eine erste Montageposition beispielsweise um eine Drehachse der Differentiallageranordnung gedreht ist. Die Drehung kann gemäß einer weiteren vorteilhaften Ausführungsvariante eine Größe von 180 Grad aufweisen. Dadurch werden möglichst viele Montagevarianten, die für unterschiedliche Achsanwendungen vorgesehen sein können, abgedeckt. According to an advantageous embodiment, the mounting positions of the differential bearing arrangement may differ in that a second mounting position is rotated relative to a first mounting position, for example about an axis of rotation of the differential bearing assembly. The rotation can according to a further advantageous embodiment have a size of 180 degrees. As a result, as many assembly variants as possible, which can be provided for different axis applications, are covered.
Um der Achsbrücke eine noch größere Variabilität zu verleihen, kann die Differentiallageranordnung so ausgeführt sein, dass deren Befestigungselemente, welche zu einer zumindest mittelbaren Befestigung eines Differentialkorbes vorgesehen sind und welche sich an den Anlageabschnitten im Achsbrückeninnenraum abstützen unterschiedlich groß ausgeführt sein, wie es eine weitere vorteilhafte Ausführungsvariante vorsieht. In order to give the axle bridge an even greater variability, the differential bearing arrangement may be designed so that its fastening elements, which are provided for at least indirect attachment of a differential cage and which are supported on the abutment sections in Achsbrückeninnenraum be designed to be different in size, as it is a further advantageous Design variant provides.
Es kann weiterhin vorteilhaft vorgesehen sein, dass die Anlageabschnitte stufenförmig mit wie jeweils mindestens zwei unterschiedlich stark in den Achsbrückeninnenraum hineinragenden Stufen ausgeführt sind. An jeder Stufe der Anlageabschnitte der Achsbrücke kann jeweils mindestens eine Anlagefläche zur AbStützung des Befestigungselements der Differentiallageranordnung ausgeführt sein. Diese können beispielsweise entlang unterschiedlich großer konzentrisch angeordneter gedachter Anlagekreise angebracht sein. Dies hat den Vorteil, dass für die gesamte Achsbrücke eine größere Freiheit bei der Ausführung ermöglicht wird. Die unterschiedlichen Anlagekreise können in der Achsbrücke in Form einer gestuften Bearbeitung umgesetzt sein. Dadurch bleibt die Differentiallageranordnung innerhalb des Achsbrückeninnen- raumes drehbar und es wird nur eine Fertigteilvariante der Achsbrücke benötigt um unterschiedliche Varianten einer Kraftfahrzeugachse herzustellen. Gemäß folgenden Figuren soll die Erfindung nun näher erläutert werden. Es zeigen: It can also be advantageously provided that the abutment sections are designed stepwise with each other as each have at least two different degrees projecting into the Achsbrückeninnenraum stages. At each stage of the contact sections of the axle bridge, in each case at least one contact surface can be designed to support the fastening element of the differential bearing arrangement. These can be mounted, for example, along different sized concentrically arranged imaginary bearing circuits. This has the advantage that a greater freedom of execution is made possible for the entire axle bridge. The different plant circuits can be implemented in the Achsbrücke in the form of a stepped processing. As a result, the differential bearing arrangement remains rotatable within the axle bridge interior and only one finished part variant of the axle bridge is required to produce different variants of a motor vehicle axle. According to the following figures, the invention will now be explained in more detail. Show it:

Dieses Kraftfahrzeug 17 umfasst einen Kraftfahrzeugmotor 20 sowie ein mit dem Kraftfahrzeugmotor 20 in einer Wirkverbindung stehendes Kraftfahrzeuggetriebe 21 . Das Kraftfahrzeuggetriebe 21 ist zumindest mittelbar mit zumindest einem Antriebsbauteil 22 mit dem Differentialkorb 18 wirkverbunden. Fig. 1 shows schematically a motor vehicle 17 with a motor vehicle axle 2 and a axle 1 which receives a differential 19 in a differential carrier 18. This motor vehicle 17 comprises a motor vehicle engine 20 and a motor vehicle transmission 21 in operative connection with the motor vehicle engine 20. The motor vehicle transmission 21 is operatively connected at least indirectly to at least one drive component 22 with the differential cage 18.
Das von dem Kraftfahrzeugmotor 20 bereitgestellte Drehmoment wird über das Kraftfahrzeuggetriebe 21 sowie zumindest einem Antriebsbauteil 22 über das Differential 19, welches in der Achsbrücke 1 in dem Differentialkorb 18 angeordnet ist, an die Kraftfahrzeugräder 23 übertragen. The torque provided by the motor vehicle engine 20 is transmitted to the motor vehicle wheels 23 via the motor vehicle transmission 21 and at least one drive component 22 via the differential 19, which is arranged in the axle box 1 in the differential carrier 18.
In der Fig. 2 ist eine beispielsweise Ausführungsvariante einer Achsbrücke 1 gemäß dem Patentanspruch 1 perspektivisch dargestellt. 2, an exemplary embodiment of a Achsbrücke 1 according to claim 1 is shown in perspective.
Es ist deutlich erkennbar, dass in dem Achsbrückeninnenraum 3 mehrere Anlageabschnitte 5, 6 zur Abstützung einer hier nicht dargestellten Differentiallageranordnung 4 ausgeführt sind. Die Anlageabschnitte 5, 6 sind stufenförmig, mit jeweils zwei Stufen 11 , 12 ausgeführt, wobei die Stufen unterschiedlich stark in den Achsbrückeninnenraum 3 hineinragen. Die Stufen weisen jeweils eine Anlagefläche 13, 14 zur AbStützung eines hier nicht dargestellten Befestigungselements 9, 10 einer Differentiallageranordnung 4 auf. It can be clearly seen that in the Achsbrückeninnenraum 3 a plurality of contact sections 5, 6 are designed to support a differential bearing assembly 4, not shown here. The contact sections 5, 6 are step-shaped, each with two stages 11, 12 executed, wherein the steps protrude different degrees in the Achsbrückeninnenraum 3. The steps each have a contact surface 13, 14 for supporting a fastening element 9, 10, not shown here, of a differential bearing arrangement 4.
In der, in Fig. 2 dargestellten Ausführungsvariante ist die Anlagefläche 13 an der Stufe 11 und die Anlagefläche 14 an der Stufe 12 eines jeden hier sichtbar abgebildeten Anlageabschnitts 5, 6 zugeordnet. Die in Fig. 2 abgebildete Ausführungsvariante stellt nur eine mögliche Ausführungsvariante dar und kann sicherlich nicht als die einzig mögliche Ausführungsvariante für die vorliegende Erfindung gesehen werden. Selbstverständlich können erfindungsgemäß auch mehr als nur zwei Anlageabschnitte, mehr Stufen an dem jeweiligen Anlageabschnitt 5, 6, 7, 8 oder auch mehrere Anlageflächen an jeder Stufe vorgesehen sein. In the variant embodiment shown in FIG. 2, the abutment surface 13 is assigned to the step 11 and the abutment surface 14 is assigned to the step 12 of each abutment section 5, 6, which is visibly depicted here. The embodiment variant shown in FIG. 2 represents only one possible embodiment variant and certainly can not be regarded as the only possible embodiment variant for the present invention. Of course, according to the invention, more than just two abutment sections, more steps on the respective abutment section 5, 6, 7, 8 or even more abutment surfaces can be provided at each step.
Gemäß der in Fig. 2 abgebildeten Ausführungen der Achsbrücke 1 sind die Anlageabschnitte 5, 6 derart ausgeführt, dass deren Stufen 11 , 12 jeweils entlang unterschiedlich großer konzentrisch angeordneter gedachter Anlagekreise 15, 16 angebracht sind, wobei jeweils zwei Stufen 11 , 12 der Anlageabschnitte 5, 6 sich entlang eines und desselben gedachten Anlagekreises 15, 16 erstrecken. According to the embodiments of the axle 1 shown in Fig. 2, the contact sections 5, 6 are designed such that their stages 11, 12 are each mounted along different sized concentric arranged imaginary contact circles 15, 16, wherein each two stages 11, 12 of the contact sections. 5 6 extend along one and the same imaginary system 15, 16.
Die Fig. 3 unterscheidet sich von der Figur 2 dadurch dass in der Fig. 3 vier Anlageabschnitte 5, 6, 7 und 8 erkennbar sind. FIG. 3 differs from FIG. 2 in that four contact sections 5, 6, 7 and 8 can be seen in FIG.
Jeder dieser vier Anlageabschnitte 5, 6, 7, 8 umfasst jeweils zwei Stufen 11 , 12, wobei an diesen Stufen 11 , 12 jeweils Anlageflächen 13, 14 ausgeführt sind.  Each of these four bearing sections 5, 6, 7, 8 each comprises two stages 11, 12, wherein at these stages 11, 12 each contact surfaces 13, 14 are executed.
Die in der Figur 3 abgebildete Achsbrücke 1 ist so ausgeführt, dass die Stufe 11 eines jeden Anlageabschnittes 5, 6, 7, 8 entlang eines gedachten Anlagekreises 15 angeordnet sind. Die Stufen 12 eines jeden Anlageabschnittes 5, 6, 7, 8 sind entlang eines gedachten Anlagekreises 16 angeordnet. Die beiden Anlagekreise 15, 16 sind koaxial zueinander angeordnet. Die Fig. 4 und Fig. 5 zeigen eine beispielsweise Ausführungsvariante der erfindungsgemäßen Achsbrücke 1 mit einer daran montierten Differentiallageranordnung 4. Dabei zeigt die Fig. 4 eine erste mögliche Montageposition der Differentiallageranordnung 4 an der Achsbrücke 1 , wobei eine zweite mögliche Montageposition der Differentiallageranordnung 4 an der Achsbrücke 1 in der Fig. 5 dargestellt ist. Dabei ist deutlich erkennbar, dass die zweite Montageposition bezogen auf die erste Montageposition um eine Drehachse A der Differentiallageranordnung 4 gedreht ist. Diese Drehung der Differentiallageranordnung um die Drehachse A kann beispielsweise bis zu 180° betragen. Die Richtung der Drehung ist dabei irrelevant. The axle bridge 1 shown in FIG. 3 is designed so that the step 11 of each contact section 5, 6, 7, 8 is arranged along an imaginary contact circle 15. The steps 12 of each contact section 5, 6, 7, 8 are arranged along an imaginary contact circle 16. The two contact circuits 15, 16 are arranged coaxially with each other. 4 shows a first possible mounting position of the differential bearing assembly 4 on the axle 1, wherein a second possible mounting position of the differential bearing assembly 4 at the axle bridge 1 in Fig. 5 is shown. It can be clearly seen that the second mounting position is rotated relative to the first mounting position about a rotational axis A of the differential bearing assembly 4. This rotation of the differential bearing arrangement about the axis of rotation A can be, for example, up to 180 °. The direction of rotation is irrelevant.
Die in den Fig. 4 und 5 abgebildete Differentiallageranordnung 4 umfasst zwei Befestigungselemente 9, 10 welche einen Differentialkorb 18 mittelbar radial und axial festlegen.
