Description
Die Erfindung betrifft ein elektrohydraulisches Aggregat zur Wandlung von elektrischer in mechanische Energie mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to an electrohydraulic aggregate for conversion from electrical to mechanical energy with the characteristics of the generic term of claim 1
Die
Aus
der
Der US 5,124,602 A ist ein Gleichstrommotor mit einem magnetischen Drehzahlsensor entnehmbar, welcher zum Antrieb einer externen Lenkhilfsvorrichtung vorgesehen ist. Der Gleichstrommotor umfasst ein topfförmiges Gehäuse, an das eine Trägerplatte für Kohlebürsten angeflanscht ist. Zwischen Trägerplatte und Gehäuse befindet sich weiterhin eine Gummimuffe, durch die elektrische Anschlusselemente zur Bestromung der Kohlebürsten nach radial außen geführt sind. Die Lager einer Motorwelle sind einerseits vollständig in dem Gehäuse des Motors und andererseits vollständig in einer Stufenbohrung der Trägerplatte aufgenommen. Zur Kupplung mit einer externen, angetriebenen Welle dient ein gesondertes Kupplungselement.Of the US 5,124,602 A is a DC motor with a magnetic speed sensor removable, which for driving an external power steering device is provided. The DC motor includes a cup-shaped housing, on the one carrier plate flanged for carbon brushes is. Between support plate and housing is still a rubber sleeve, through the electrical connection elements for energizing the carbon brushes radially outward guided are. The bearings of a motor shaft are on the one hand completely in the housing of the engine and on the other hand completely in a stepped bore the carrier plate added. For coupling with an external, driven shaft serves a separate coupling element.
Bei der im Hauptpatent beschriebenen elektrischen Maschine hat es sich gezeigt, daß zur sicheren Befestigung des wellenseitigen Festlagers im Gehäuse des Aufnahmekörpers sehr enge Passungstoleranzen eingehalten werden müssen, die zu unterschiedlichen Montagekräften führen. Als weiterer Nachteil sind die fehlenden Fixierhilfen zur exakten Positionierung des Festlagers im Gehäuse zu nennen, damit die erforderliche Einbautiefe der Welle im Aufnahmekörper eingehalten werden kann.at the electric machine described in the main patent has it shown that to secure attachment of the shaft side fixed bearing in the housing of receiving body very tight fitting tolerances must be respected to different assembly forces to lead. Another disadvantage is the lack of fixing to the exact Calling positioning of the fixed bearing in the housing, so that the required Installation depth of the shaft can be maintained in the receiving body.
Für die Befestigung konventioneller Festlager müssen enge Passungstoleranzen im Presspassungsbereich eingehalten werden. Denn Ungenauigkeiten führen zu stark unterschiedlichen Montagekräften beim Einpressen des Lagers. Wenn die Motorwelle und die Pumpenwelle einstückig ausgebildet sind, beeinflussen diese Randbedingungen auch unmittelbar die Positionierung des Festlagers und mithin der Welle. Es hat sich daher als schwierig erwiesen, eine bestimmte Einbautiefe einzuhalten.For the attachment conventional storage tight fitting tolerances are maintained in the press-fit area. Because inaccuracies lead too much different assembly forces when pressing the bearing. When the motor shaft and the pump shaft are integrally formed, influence These boundary conditions also directly the positioning of the fixed bearing and therefore the wave. It has therefore proved difficult to maintain a certain installation depth.
Der Erfindung liegt die Aufgabe zugrunde, ein elektrohydraulisches Aggregat der eingangs genannten Gattung derart weiter zu entwickeln, daß unter Umgehung der vorgenannten Nachteile eine präzise und dennoch leicht montierbare Wellenlagerung ermöglicht wird, die auch einstellbar ist.Of the Invention is based on the object, an electro-hydraulic unit of the aforementioned type to develop such that under To circumvent the aforementioned disadvantages a precise and yet easy to install Shaft bearing allows which is also adjustable.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöstThese The object is achieved by the characterizing features of claim 1 solved
Durch die in den Unteransprüchen aufgezeigten Maßnahmen sind zweckmäßige Ausbildungen der Erfindung angegeben, die im Zusammenhang mit den weiteren Merkmalen und Vorteilen der Erfindung nachfolgend anhand einer Zeichnung näher dargestellt und erläutert werden.By in the subclaims identified measures are appropriate training of the invention, in connection with the other features and advantages of the invention shown below with reference to a drawing and explained become.
