Abstract
Motor/Pumpen-Aggregat, insbesondere für ein Servolenksystem, mit einem Pumpengehäuse (14) und einem Zwischengehäuse (16), wobei im Pumpengehäuse (14) eine Pumpe mit einer ersten Pumpenwelle (30) aufgenommen ist, dadurch gekennzeichnet, daß das Pumpengehäuse (14) und das Zwischengehäuse (16) über einen Flansch (20) miteinander verbunden sind und die erste Pumpenwelle (30) im Flansch (20) gelagert ist.Motor / pump unit, especially for a power steering system with a pump housing (14) and an intermediate housing (16), being in the pump housing (14) a pump with a first pump shaft (30) is received, characterized in that the pump housing (14) and the intermediate case (16) about one Flange (20) are interconnected and the first pump shaft (30) is mounted in the flange (20).
Description
Die Erfindung betrifft ein Motor/Pumpen-Aggregat, insbesondere für ein Servolenksystem, mit einem Pumpengehäuse und einem Zwischengehäuse, wobei im Pumpengehäuse eine Pumpe mit einer ersten Pumpenwelle aufgenommen ist.The The invention relates to a motor / pump unit, in particular for a power steering system, with a pump housing and an intermediate case, wherein in the pump housing a pump is received with a first pump shaft.
Solche Motorpumpenaggregate werden in der Kfz-Technik zur Bereitstellung von Hilfskräften eingesetzt. Neben der Unterstützung der Lenkkraft kann ein solches Aggregat auch bei einer aktiven Fahrwerkregelung Verwendung finden. Es besteht ein allgemeiner Bedarf, die Motor/Pumpen-Aggregate noch kompakter zu gestalten.Such Motor pump units are used in automotive engineering used by assistants. In addition to the support Such a unit can also control the steering force with active chassis control Find use. There is a general need, the motor / pump units to make it even more compact.

Die Erfindung schafft ein kompaktes, funktionsoptimiertes, aber dennoch kostengünstiges Motor/Pumpen-Aggregat.The Invention creates a compact, functionally optimized, yet cost-effective Motor / pump unit.
Gemäß der Erfindung ist bei einem Motor/Pumpen-Aggregat der eingangs genannten Art vorgesehen, daß das Pumpengehäuse und das Zwischengehäuse über einen Flansch miteinander verbunden sind und die erste Pumpenwelle im Flansch gelagert ist. Die Lagerung der Pumpenwelle im Flansch erlaubt im Gegensatz zu einer Lagerung im Zwischengehäuse eine sehr kurze Auslegung der Pumpenwelle. Dadurch ergeben sich geringere Rundlaufabweichungen, weshalb nur relativ unaufwendige Kompensationsmaßnahmen erforderlich sind.According to the invention is provided in a motor / pump unit of the type mentioned at the beginning, that this pump housing and the intermediate housing over one Flange are interconnected and the first pump shaft in Flange is mounted. The bearing of the pump shaft in the flange allows in contrast to storage in the intermediate housing, a very short design the pump shaft. This results in lower runout deviations, which is why only relatively inexpensive compensation measures are required.
Eine solche Kompensation wird insbesondere dadurch erreicht, daß die erste Pumpenwelle in einer Buchse gelagert ist, die in einem das Pumpengehäuse verschließenden Gehäusedeckel gebildet ist.A such compensation is achieved in particular in that the first Pump shaft is mounted in a socket in a housing cover that closes the pump housing is formed.
Gemäß der bevorzugten Ausführungsform der Erfindung faßt die Pumpe eine zweite Pumpenwelle, die neben der ersten Pumpenwelle angeordnet und ebenfalls im Flansch gelagert ist. Die Pumpenwellen können jeweils einstückig mit einem Zahnrad ausgebildet sein.According to the preferred Embodiment of the Invention summarizes the pump has a second pump shaft next to the first pump shaft arranged and also mounted in the flange. The pump shafts can each in one piece be formed with a gear.
Der Flansch ist vorzugsweise eine gestanzte Platte aus einer Aluminiumlegierung. Zur Verbesserung der Dichtfunktion und der Geräuschdämpfung ist der Flansch wenigstens teilweise mit einer NBR (Nitrilkautschuk)-Beschichtung versehen. Die Flanschgröße ist auf die baulichen Gegebenheiten des Motor/Pumpen-Aggregats und eventuelle zusätzliche Funktionen des Flanschs (z. B. Kühlung) abgestimmt.The The flange is preferably a stamped plate made of an aluminum alloy. To improve the sealing function and noise reduction, the flange is at least partially with an NBR (nitrile rubber) coating. The flange size is on the structural conditions of the motor / pump unit and any additional functions of the flange (e.g. cooling) Voted.
Zur Vereinfachung und Verbesserung der Zentrierung des Pumpengehäuses gegenüber dem Zwischengehäuse, welche bisher indirekt über zwischen dem Pumpengehäuse und dem Flansch sowie zwischen dem Flansch und dem Zentriergehäuse vorgesehene Zentrierstifte erfolgt, wird vorgeschlagen, daß wenigstens ein Zentrierstift vorgesehen ist, der vom Pumpengehäuse durch den Flansch hindurch in das Zwischengehäuse ragt.to Simplification and improvement of the centering of the pump housing compared to the intermediate housing, which so far indirectly via between the pump housing and the flange and provided between the flange and the centering housing Centering pins takes place, it is proposed that at least one centering pin is provided, from the pump housing through the flange in the intermediate housing protrudes.
Auf ein separates Motorgehäuse, das positionsgenau am Zwischengehäuse befestigt werden müßte, kann verzichtet werden, indem in einem Abschnitt des Zwischengehäuses ein Elektromotor des Motor/Pumpen-Aggregats aufgenommen ist.On a separate motor housing, that would have to be fixed in position on the intermediate housing, can to be dispensed with by placing it in a section of the intermediate housing Electric motor of the motor / pump unit is added.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus der beigefügten Zeichnung, auf die Bezug genommen wird. In der Zeichnung zeigt die einzige Figur eine geschnittene Seitenansicht eines erfindungsgemäßen Motor/Pumpen-Aggregats.Further Features and advantages of the invention result from the following Description and from the attached Drawing to which reference is made.
