Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Hydroaggregat (zB DE-A-3 144 983) nach dem Oberbegriff des Anspruchs 1. Derartige, in der Praxis verwendete Hydroaggregate bestehen aus einer Pumpe und einem mit der Pumpe verbundenen Anschlußelement, das vorzugsweise aus Aluminium besteht, und im Druckgußverfahren hergestellt ist. Im Anschlußelement sind Kanäle für das Druckmittel durch spanende Verfahren wie bsw. Drehen oder Bohren ausgebildet. Das Anschlußelement ist zusammen mit der Pumpe an einen Antriebsmotor angeflanscht. Nachteilig dabei ist, daß das gesamte Anschlußelement wegen den Kanälen für das Druckmittel aus hochdruckfestem Material besteht. Dadurch ist es relativ teuer in der Herstellung und darüberhinaus auch relativ schwer. Weiterhin benötigt die Ausbildung der Kanäle bsw. durch Umspannen des Anschlußelements in einer Werkzeugmaschine einen relativ hohen Handhabungsaufwand. Das Geräusch- bzw. Vibrationsverhalten des..Hydroaggregats ist zudem relativ schlecht, da dieses durch die Ausbildung des Anschlußelements in Metall kaum Dämpfungseigenschaften besitzt.

The connection element is together with the pump flanged to a drive motor. The disadvantage is that the entire connector because of the channels for the Pressure medium consists of high pressure resistant material. Thereby it is relatively expensive to manufacture and beyond also relatively difficult. The training of Channels or by reclamping the connection element in a Machine tool requires a relatively high level of handling. The Noise or vibration behavior of the hydraulic unit also relatively bad, since this is due to the training of Connection element in metal hardly damping properties owns.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Hydroaggregat mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß es relativ preiswert in der Herstellung und besonders leicht ist. Die Handhabung während der Herstellung ist besonders einfach, da die Einsetzteile lediglich in das Anschlußelement eingesetzt werden müssen. Durch die Verwendung von Kunststoff für das Anschlußelement wird außerdem eine besonders gute Geräusch- und Vibrationsdämpfung erzielt.The hydraulic unit according to the invention with the characteristic Features of claim 1 has the advantage that it is relatively inexpensive to manufacture and particularly light is. Handling during manufacture is special easy, because the insert parts only in the Connection element must be used. Through the Use of plastic for the connection element also a particularly good noise and Vibration damping achieved.

Weitere Vorteile und vorteilhafte Weiterbildungen des erfindungsgemäßen Hydroaggregats ergeben sich aus den Unteransprüchen und der Beschreibung. Werden die Ausnehmungen jeweils stets mit demselben Durchmesser ausgebildet, können die Einsetzteile durch unterschiedliche Innendurchmesser leicht unterschiedlichen hydraulischen Parametern der angeflanschten Aggregate angepaßt werden. Günstigstenfalls kann auf jegliche spanende Verarbeitung des Anschlußelements verzichtet werden, was dessen Herstellkosten zusätzlich verringert.Further advantages and advantageous developments of the Hydraulic unit according to the invention result from the Subclaims and the description.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Figur 1 zeigt ein Hydroaggregat in Seitenansicht und teilweise im Längsschnitt.An embodiment of the invention is in the drawing shown and is described in more detail in the following description explained. Figure 1 shows a hydraulic unit in side view and partly in longitudinal section.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Das Hydroaggregat besteht aus einer Pumpe 10 und einem mit der Pumpe 10 verbundenen Anschlußelement 11. Das aus Kunststoff bestehende Anschlußelement 11 ist in etwa scheibenförmig ausgebildet und hat in seiner Mittelachse 12 verlaufend zwei Bohrungen 14, 15, die von einem durch das Anschlußelement 11 gebildeten Führungssteg 16 voneinander getrennt sind.The hydraulic unit consists of a pump 10 and a the pump 10 connected connector 11. That from Plastic existing connector 11 is approximately disc-shaped and has 12 in its central axis running two holes 14, 15, one of which through the Connection element 11 formed guide web 16 from each other are separated.

Die Pumpe 10 ist mit dem Anschlußelement 11 bsw. durch Anschrauben so verbunden, daß der Fortsatz 18 und die Antriebswelle 19 der Pumpe 10 in die erste Bohrung 14 des Anschlußelements 11 hineinragen. Die Bohrung 14 ist so ausgebildet, daß sie den Fortsatz 18 formschlüssig umschließt. Weiterhin liegen die jeweiligen Stirnflächen 20, 21 der Pumpe 10 bzw. des Anschlußelements 11 in deren Überdeckungsbereich plan aneinander an.The pump 10 is bsw with the connecting element 11. by Screwed connected so that the extension 18 and the Drive shaft 19 of the pump 10 in the first bore 14 of the Project connection element 11. The bore 14 is like this trained that they form-fitting the extension 18 encloses. Furthermore, the respective end faces 20, 21 of the pump 10 or the connecting element 11 in their Cover area flat against each other.

Auf der der Pumpe 10 gegenüberliegenden Seite des Anschlußelements 11 ist das Hydroaggregat bsw. an einen nicht dargestellten Antriebsmotor für die Pumpe 10 angeflanscht. Dazu ist in der Stirnfläche 22 des Anschlußelements 11 eine Aufnahme 23 ausgebildet, die die entsprechende Stirnseite des Antriebsmotors formschlüssig umschließt. Eine am Anschlußelement 11 angeformte Nase 24 dient der Verdrehsicherung bzw. des lagerichtigen Einbaus des Antriebsmotors. Wie bei der Pumpe 10 auf der gegenüberliegenden Seite ragt ein entsprechender Fortsatz des Antriebsmotors formschlüssig in die andere Bohrung 15. Zum Ankuppeln des Antriebsmotors an die Pumpe 10 wird die Antriebswelle des Antriebsmotors durch den Führungssteg 16 geführt.On the opposite side of the pump 10 Connection element 11 is the hydraulic unit bsw. at one Drive motor, not shown, for the pump 10 flanged. For this purpose, in the end face 22 of the Connection element 11 formed a receptacle 23, which corresponding end face of the drive motor with a positive fit encloses. A nose 24 formed on the connection element 11 serves to prevent rotation or installation in the correct position of the drive motor. As with the pump 10 on the a corresponding extension protrudes from the opposite side of the drive motor in the other hole 15. To couple the drive motor to the pump 10, the Drive shaft of the drive motor through the guide web 16 guided.

In der der Pumpe 10 zugewandten Stirnfläche 21 und am Umfang ist im Anschlußelement 11 jeweils eine Ausnehmung 26, 27 ausgebildet, die ineinander rechtwinklig münden. Die Ausnehmungen 26, 27 sind entweder bsw. durch Bohren spanend hergestellt, oder sind bevorzugt schon im Spritzwerkzeug für das Anschlußelement 11 entsprechend berücksichtigt, d.h., daß sich die Ausnehmungen 26, 27 durch das Ausspritzen des Anschlußelements 11 ergeben. In den Ausnehmungen 26, 27 ist jeweils ein aus Metall bestehendes Druckmittelrohr 28, 29 eingesetzt, wobei der Außendurchmesser des Rohres 29 größer ist als der Außendurchmesser des Rohres 28. Das Rohr 28 ragt mit einem Ende in das Rohr 29, und das andere Ende des Rohres 28 ragt aus der Stirnfläche 21 des Anschlußelements 11. Dort ist es von einer entsprechenden Druckmittelanschlußbohrung 30 der Pumpe 10 umfasst. Da die im Innern der Rohre 28, 29 ausgebildeten Bohrungen 31, 32 ebenfalls rechtwinklig ineinander münden, ist somit eine durchgehende Verbindung für ein Druckmittel von dem aus dem Anschlußelement 11 ragenden Ende des Rohres 29 zur Anschlußbohrung 30 der Pumpe 10 gebildet. Die Größe der Durchmesser der Bohrungen 31, 32 sind entsprechend des gewünschten Durchflußquerschnittes für das Druckmittel ausgebildet. Zur Abdichtung der Rohre 28, 29 gegenüber der Pumpe 10 bzw. dem Anschlußelement 11 sind in umlaufenden Nuten der Rohre 28, 29 Dichtungsringe 33 angeordnet.In the end face 21 facing the pump 10 and on the circumference there is a recess 26, 27 in the connecting element 11 trained, which open into each other at right angles. The Recesses 26, 27 are either BSW. cutting by drilling manufactured, or are preferably already in the injection mold for the connecting element 11 is taken into account accordingly, i.e. that the recesses 26, 27 by spraying the Connection element 11 result. In the recesses 26, 27 is each a pressure medium tube 28, 29 made of metal used, the outer diameter of the tube 29 larger is than the outer diameter of the tube 28. The tube 28 protrudes with one end in the tube 29, and the other end of the Tube 28 protrudes from the end face 21 of the connecting element 11. There it is from a corresponding one Pressure medium connection bore 30 of the pump 10 comprises. Since the bores 31, 32 formed in the interior of the tubes 28, 29 also merge at right angles is one continuous connection for a pressure medium from which Connection element 11 projecting end of the tube 29 for Connection bore 30 of the pump 10 is formed. The size of the Diameters of the bores 31, 32 are corresponding to the Desired flow cross section for the pressure medium educated. To seal the tubes 28, 29 against the Pump 10 and the connecting element 11 are rotating Grooves of the tubes 28, 29 sealing rings 33 are arranged.

Beim Betrieb des oben beschriebenen Hydroaggregats ist das aus dem Umfang des Anschlußelements 11 ragende Ende des Rohres 29 mittels einer nicht dargestellten Druckmittelleitung bsw. mit einem Vorratsbehälter für das Druckmittel verbunden. Die Pumpe 10 kann somit mittels der Druckmittelleitung und der Rohre 28, 29 Druckmittel aus dem Vorratsbehälter ansaugen, verdichten, und über einen nicht dargestellten Auslaß der Pumpe 10 zu einem Verbraucher weiterleiten.When operating the hydraulic unit described above, this is from the circumference of the connecting element 11 protruding end of Tube 29 by means of a not shown Pressure medium line or with a storage container for that Pressure medium connected. The pump 10 can thus by means of Pressure medium line and the tubes 28, 29 pressure medium from the Vacuum, compress, and not over one shown outlet of the pump 10 to a consumer hand off.

Wird eine Pumpe 10 mit geänderten hydraulischen Parametern an das Anschlußelement 11 angeflanscht, so kann dem über entsprechend größere oder kleinere Durchmesser der Bohrungen 31, 32 in den Rohren 28, 29 Rechnung getragen werden. Die Größe der Ausnehmungen 26, 27 in dem Anschlußelement 11 kann jedoch unverändert bleiben. If a pump 10 with changed hydraulic parameters flanged to the connecting element 11, so that can correspondingly larger or smaller diameter of the holes 31, 32 in the tubes 28, 29 are taken into account. The Size of the recesses 26, 27 in the connecting element 11 can however remain unchanged.

Ergänzend wird bemerkt, daß anstelle der Rohre 28, 29 auch andersartig ausgebildete Elemente zur Leitung bzw. Führung des Druckmittels verwendet werden können. Diese können bsw. einen mehreckigen Querschnitt aufweisen, wobei die Ausnehmungen 26, 27 entsprechend anzupassen sind.In addition, it is noted that instead of the tubes 28, 29 also differently designed elements for management or leadership of the pressure medium can be used. These can be have a polygonal cross section, the Recesses 26, 27 are to be adapted accordingly.
