Description

Differentiallaqeranordnunq  Differentiallaqeranordnunq
Die Erfindung betrifft eine Differentiallageranordnung zur Lagerung eines Differentialkorbes in einer Achsbrücke einer Kraftfahrzeugachse. The invention relates to a differential bearing arrangement for mounting a differential cage in a axle bridge of a motor vehicle axle.
Eine gattungsgemäße Differentiallageranordnung ist beispielsweise aus der DE 2006 012 342 A1 bekannt. Diese umfasst ein Achsantriebsgehäuse mit einem ersten Abschnitt und einem zweiten Abschnitt, welche durch einen Befestigungskranz zur Befestigung des Achsantriebsgehäuses an einer Achsbrücke einer Fahrzeugachse voneinander getrennt sind. An dem ersten Abschnitt des Achsantriebsgehäuses ist mindestens eine zweiteilig ausgeführte Lageraufnahmeanordnung angebracht, welche den Differentialkorb zumindest mittelbar aufnimmt. Die Lageraufnahmeanordnung besteht aus einem, einteilig mit dem Achsantriebsgehäuse ausgeführten Lageraufnahmeelement und einem Lagerbügel, welcher mit mindestens einer Befestigungsschraube mit dem Lageraufnahmeelement des Achsantriebsgehäuses fest verbunden ist. Die Verbindung des Lagerbügels mit dem Achsantriebsgehäuse ist üblicherweise derart ausgeführt, dass ein Schraubenkopf der Befestigungsschraube an dem Lagerbügel anliegt und ein zylindrischer Schraubenkörper der Befestigungsschraube durch eine im Lagerbügel ausgeführte Durchgangsbohrung durchgeführt ist und in einem im Lageraufnahmeelement des Achsantriebsgehäuses ausgeführte Bohrung eingreift, welche mit einem Innengewinde versehen ist. A generic differential bearing arrangement is known for example from DE 2006 012 342 A1. This comprises an axle drive housing having a first section and a second section, which are separated from one another by a fastening ring for fastening the final drive housing to an axle bridge of a vehicle axle. At least a two-part bearing mounting arrangement is mounted on the first portion of the axle drive housing, which accommodates the differential carrier at least indirectly. The bearing receiving arrangement consists of a one-piece bearing with the final drive housing bearing receiving element and a bearing bracket, which is fixedly connected to at least one fastening screw with the bearing receiving element of the final drive housing. The connection of the bearing bracket with the axle drive housing is usually designed such that a screw head of the fastening screw rests against the bearing bracket and a cylindrical screw body of the fastening screw is performed by a through hole made in the bearing bracket and engages in an executed in the bearing receiving element of the final drive housing bore, which with an internal thread is provided.
Die Lageraufnahmeanordnung weist eine Lageraufnahmeöffnung zur Aufnahme eines Differentiallagers auf. Die Lageraufnahmeöffnung ist teilweise in dem Lageraufnahmeelement des Antriebsgehäuses und teilweise in dem Lagerbügel ausgeführt, so dass durch den Zusammenbau dieser beiden Elemente eine vollständige Lageraufnahmeöffnung zur Aufnahme eines Differentiallagers entsteht. The bearing receiving arrangement has a bearing receiving opening for receiving a differential bearing. The bearing receiving opening is partially carried out in the bearing receiving element of the drive housing and partially in the bearing bracket, so that the assembly of these two elements creates a complete bearing receiving opening for receiving a differential bearing.
Um eine erforderliche hohe Genauigkeit der Lageraufnahmeöffnung gewährleisten zu können, müssen bei der Fertigung die Bauteile, das Lageraufnahmeelement und der Lagerbügel, zuerst montiert und dann gemeinsam bearbeitet werden. Die zusammengehörenden Teile, das Lageraufnahmeelement und der Lagerbügel, müssen dann wieder demontiert und gepaart für die Endmontage der Achsbrücke ausgeliefert werden. Diese Montagereihenfolge, die strikt eingehalten werden muss, bedeutet einen hohen Fertigungsaufwand und ist somit mit hohen Fertigungskosten verbunden. Darüber hinaus besteht eine Verwechslungsgefahr bei den ausgelieferten Lagerbügeln zu den Lageraufnahmeelementen des Achsantriebsgehäuses. Werden diese vertauscht, so kann eine einwandfreie Montage des Differentiallagers in der Differentiallageranordnung nicht gewährleistet werden. In order to ensure a required high accuracy of the bearing receiving opening, the components, the bearing receiving element and the bearing bracket, must be assembled first and then processed together. The mating parts, the bearing support element and the bearing bracket, must then be disassembled and paired delivered for final assembly of the axle. This assembly order, which must be strictly adhered to, means a high production cost and is therefore associated with high production costs. In addition, there is a likelihood of confusion in the delivered bearing brackets to the bearing receiving elements of the final drive housing. If these are interchanged, a perfect mounting of the differential bearing in the differential bearing arrangement can not be guaranteed.
Aufgabe der vorliegenden Erfindung ist es demnach eine Differentiallageranordnung zur Lagerung eines Differentialkorbes anzugeben bei der der Aufwand der Fertigung und der Montage, so wie die Montagekosten verringert sind. Object of the present invention is therefore to provide a differential bearing assembly for supporting a differential cage in which the cost of manufacturing and assembly, as the installation costs are reduced.
Diese Aufgabe wird gemäß dem Patentanspruch 1 dadurch gelöst, dass das Lageraufnahmeelement als ein separates, einteiliges Bauteil ausgeführt ist, welches mit Hilfe mindestens eines Befestigungsmittels mit dem Achsantriebsgehäuse fest verbunden ist und wobei das Lageraufnahmeelement einen daran ausgeführten La- geraufnahmedurchbruch, zur Aufnahme eines Differentiallagers für den Differentialkorb aufweist. This object is achieved according to claim 1, characterized in that the bearing receiving element is designed as a separate, one-piece component, which is fixedly connected by means of at least one fastening means with the final drive housing and wherein the bearing receiving element thereon carried out gerager opening, for receiving a differential bearing for has the differential carrier.
Dadurch kann der Lageraufnahmedurchbruch des Lageraufnahmeelements, unabhängig von dem Achsantriebsgehäuse bearbeitet werden. Eine Verwechslung der eine Lageraufnahme bildenden Bauteile ist dadurch ausgeschlossen. Thereby, the bearing receiving aperture of the bearing receiving member can be processed independently of the final drive housing. A confusion of a bearing receiving components forming is excluded.
Weitere vorteilhafte Ausführungsvarianten der vorliegenden Erfindung sind in den abhängigen Ansprüchen so wie in den Figuren angegeben. Further advantageous embodiments of the present invention are given in the dependent claims as in the figures.
Gemäß einer vorteilhaften Ausführungsvariante umfasst das Lageraufnahmeelement einen Aufnahmeabschnitt und einen daran angrenzenden Befestigungsabschnitt. Der Lageaufnahmedurchbruch ist dabei in dem Aufnahmeabschnitt des Lageraufnahmeelements ausgeführt. Der Befestigungsabschnitt umfasst mindestens einen Befestigungsdurchbruch für das Befestigungsmittel. Somit kann das Lageraufnahmeelement auf eine einfache Weise mit Hilfe eines Befestigungsmittels mit dem Achsantriebsgehäuse verbunden werden. Das Lageraufnahmeelement kann, wie in einer weiteren vorteilhaften Ausführungsvariante dargestellt, bei einer montierten Differentiallageranordnung mit dessen Befestigungsabschnitt direkt an dem Achsantriebsgehäuse zur Anlage kommen. Das Lageraufnahmeelement kann so ausgeführt sein, dass bei einer montierten Differentiallageranordnung der Befestigungsabschnitt des Lageraufnahmeelements zwischen dem Achsantriebsgehäuse und dem Aufnahmeabschnitt des Lageraufnahmeelements angeordnet ist. According to an advantageous embodiment, the bearing receiving element comprises a receiving portion and an adjoining attachment portion. The bearing receiving opening is designed in the receiving portion of the bearing receiving element. The attachment portion includes at least one attachment opening for the attachment. Thus, the bearing receiving member can be connected in a simple manner by means of a fastener with the final drive housing. The bearing receiving element can, as shown in a further advantageous embodiment, come in a mounted differential bearing assembly with its attachment portion directly to the final drive housing to the plant. The bearing receiving element may be designed so that is arranged at a mounted differential bearing assembly of the mounting portion of the bearing receiving element between the axle drive and the receiving portion of the bearing receiving member.
Gemäß einer weiteren vorteilhaften Ausführungsvariante umfasst die Differenzialla- geranordnung mindestens einen Positionierungsbolzen welcher eine Montageposition des Lagerbügels gegenüber dem Achsantriebsgehäuse festlegt. Der Positionierungsbolzen kann sowohl einteilig mit dem Lagerbügel als auch ebenfalls einteilig mit dem Achsantriebsgehäuse ausgeführt sein. Selbstverständlich kann der Positionierungsbolzen auch als ein zusätzliches separates Bauteil ausgeführt sein. According to a further advantageous embodiment, the Differenzialla- geranordnung comprises at least one positioning pin which defines a mounting position of the bearing bracket relative to the final drive housing. The positioning bolt can be designed both in one piece with the bearing bracket and also in one piece with the axle drive housing. Of course, the positioning bolt can also be designed as an additional separate component.
Ist der Positionierungsbolzen als ein separates Bauteil oder einteilig mit dem Achsantriebsgehäuse ausgeführt, so kann es vorteilhaft sein, dass der Lagerbügel zumindest eine erste Ausnehmung aufweist welche der Aufnahme des Positionierungsbolzens dient. If the positioning bolt is designed as a separate component or integrally with the axle drive housing, then it may be advantageous for the bearing bracket to have at least one first recess which serves to receive the positioning bolt.
Ist der Positionierungsbolzen einteilig mit dem Lagerbügel oder als ein separates Bauteil ausgeführt, so kann das Antriebsgehäuse zumindest eine zweite Ausnehmung zur Aufnahme des Positionierungsbolzens aufweisen. If the positioning bolt is made in one piece with the bearing bracket or as a separate component, then the drive housing can have at least one second recess for receiving the positioning bolt.
Gemäß einer weiteren vorteilhaften Ausführungsvariante der Differenziallageranord- nung weist der Lagerbügel und das Antriebsgehäuse jeweils eine Ausnehmung zur Aufnahme des Positionierungsbolzens auf. According to a further advantageous embodiment of the Differenziallageranord- tion of the bearing bracket and the drive housing each have a recess for receiving the positioning pin.
Der Lagerbügel und das Achsantriebsgehäuse werden in diesem Fall derart zueinander ausgerichtet, dass die erste Ausnehmung des Lagerbügels und die zweite Ausnehmung des Achsantriebsgehäuses einander überlagern und dass der separat ausgeführte Positionierungsbolzen innerhalb der beiden Ausnehmungen angeordnet ist und somit die Position des Lagerbügels zu dem Achsantriebsgehäuse festlegt. Anhand folgender Figuren soll die Erfindung nun näher erläutert werden. Es zeigen: The bearing bracket and the axle drive housing are in this case aligned with each other so that the first recess of the bearing bracket and the second recess of the final drive housing overlap each other and that the separately executed positioning pin is disposed within the two recesses and thus determines the position of the bearing bracket to the final drive housing. With reference to the following figures, the invention will now be explained in more detail. Show it:

Das Lageraufnahmeelement 8 ist als ein separates, einteiliges Bauteil ausgeführt. Das Lageraufnahmeelement 8 umfasst einen Aufnahmeabschnitt 14 und einen daran angrenzenden Befestigungsabschnitt 15. In dem Aufnahmeabschnitt 14 des Lageraufnahmeelements 8 ist ein Lageraufnahmedurchbruch 10 zur Aufnahme eines Differentiallagers 18 für den Differentialkorb 17 ausgeführt. Der Befestigungsabschnitt 15 des Lageraufnahmeelements 8 weist mehrere Befestigungsdurchbrüche 16 für die Befestigungsmittel 9 auf. Es ist deutlich erkennbar, dass das Lageraufnahmeelement 8 bei einer montierten Differentiallageranordnung 1 mit dessen Befestigungsabschnitt 15 an dem Achsantriebsgehäuse 2 zur Anlage kommt und dass der Befestigungsabschnitt 15 des Lageraufnahmeelements 8 zwischen dem Achsantriebsgehäuse 2 und dem Aufnahmeabschnitt 14 des Lageraufnahmeelements 8 angeordnet ist. The two-part design of the bearing receiving arrangement 7 is shown in FIG. 2 even more clearly.
