Description

Die Erfindung betrifft ein Hydraulikaggregat mit zumindest einem elektronischen Bauteil, einer Pumpe, deren Kolben mittels einer angetriebenen Welle hin- und herbewegbar sind, und mit Dichtmitteln zwischen der Pumpe und dem elektronischen Bauteil.The invention relates to a hydraulic unit with at least an electronic component, a pump, the piston can be moved back and forth by means of a driven shaft, and with sealant between the pump and the electronic component.

Da sowohl die Wicklung eines Antriebsmotors der Pumpe als auch Einheiten für die elektronische Regelung von derartigen Hydraulikaggregaten insbesondere bei hydraulischen Bremsanlagen gegen das Eindringen von Hydraulikflüssigkeit, Fett, Staub und Feuchtigkeit sehr empfindlich sind, wählt man im allgemeinen eine Einbaulage, bei der die elektronischen Teile oberhalb der Pumpe angeordnet sind. Wo das nicht möglich ist, müssen besondere Maßnahmen ergriffen werden, um einerseits das Eindringen von Hydraulik­ flüssigkeit in die elektronischen Bauteile zu vermeiden, andererseits aber die notwendige Belüftung des Motors nicht zu behindern. Aber auch bei Fällen, in denen die Pumpe unterhalb des Motors angeordnet ist, kann es beispielsweise durch Fliehkräfte bei Kurvenfahrten etc. zu einem Eindringen von Verunreinigungen aus der Pumpe in den Motor bzw. andere elektronische Bauteile kommen.Because both the winding of a drive motor of the pump and also units for the electronic regulation of such Hydraulic units, especially in hydraulic Braking systems against the ingress of hydraulic fluid, Grease, dust and moisture are very sensitive chooses generally a mounting position in which the electronic parts are arranged above the pump. Where that is not possible, special measures must be taken be on the one hand the penetration of hydraulics to avoid liquid in the electronic components, on the other hand, the necessary ventilation of the engine is not to hinder. But also in cases where the pump is arranged below the engine, for example penetration by centrifugal forces when cornering etc. of contaminants from the pump to the motor or others electronic components come.

Dabei ist es bereits bekannt, daß die Lagerstelle der Welle des Antriebsmotors im Pumpengehäuse abdichtend ausgebildet ist. Es hat sich jedoch herausgestellt, daß eine gänzliche Abdichtung hier nicht oder nur mit unvertretbar hohem konstruktiven Aufwand erreicht werden kann. Man rechnet daher stets mit einer gewissen Leckageflüssigkeitsmenge, die beispielsweise durch die Lagerung in den Bereich der empfindlichen elektronischen Bauteile gelangen kann.It is already known that the bearing point of the shaft of the drive motor in the pump housing sealing is. However, it has been found that a complete Sealing not here or only with an unacceptably high constructive effort can be achieved. You do the math  therefore always with a certain amount of leakage fluid for example by storage in the area of sensitive electronic components.

Der Erfindung liegt die Aufgabe zugrunde, den dadurch möglicherweise auftretenden Schaden wirksam zu vermeiden und die gefährdeten Bauteile verläßlich gegen das Eindringen von insbesondere Hydraulikflüssigkeit zu schützen. Außerdem soll die gesuchte Maßnahme mit geringem konstruktiven und fertigungstechnischem Aufwand realisierbar sein und die Belüftung des Motorraums möglichst nicht behindern.The invention is based on the object effectively avoid possible damage and the vulnerable components reliably against the ingress of especially to protect hydraulic fluid. In addition, should the measure sought with little constructive and production engineering effort can be realized and the Avoid obstructing ventilation in the engine compartment if possible.

Zur Lösung dieser Aufgabe wird bei dem eingangs genannten Hydraulikaggregat vorgeschlagen, daß zwischen zumindest einem Dichtmittel, wie beispielsweise einem dichtend ausgeführten Wellenlager, und wenigstens einem elektronischen Bauteil zusätzlich Mittel zur Ableitung von Flüssigkeit vorgesehen sind.To solve this problem, the above mentioned Hydraulic unit suggested that between at least a sealant such as a seal executed shaft bearing, and at least one electronic component additional means for deriving Liquid are provided.

Dazu ist vorzugsweise die Welle des Antriebsmotors mit einer Schleuderscheibe versehen, mittels derer durch das Lager austretende Leckageflüssigkeit in einen Ringraum ableitbar ist, der seinerseits über einen Kanal mit einer Ölsammelstelle verbunden sein kann. Dadurch wird wirksam vermieden, daß Verunreinigungen aus der Pumpe zu deren Antriebsmotor und/oder anderen elektronischen Teilen gelangen.For this purpose, the shaft of the drive motor is preferably one Slingshot disc, by means of which through the camp escaping leakage fluid can be drained into an annular space which in turn is connected via a channel with a Oil collection point can be connected. This will take effect avoided contaminants from the pump to its Drive motor and / or other electronic parts reach.

Die erfindungsgemäßen Ableitmittel sind insbesondere dann von Vorteil, wenn der Motor bzw. andere elektronische Bauteile bezüglich eines Gravitationsfeldes unterhalb der Pumpe angeordnet sind. The discharge means according to the invention are particularly then beneficial if the engine or other electronic Components related to a gravitational field below the Pump are arranged.  

Vorzugsweise weist der Antriebsmotor einen Gehäusestutzen auf, der im Gehäuse der Pumpe dichtend geführt ist. Für die Belüftung des Motors ist insbesondere zwischen dessen Welle und dem Gehäusestutzen ein Be- bzw. Entlüftungsspalt vorgesehen. Dieser Ringspalt ist von der Schleuderscheibe überdeckt, so daß von oben kommende Leckageflüssigkeit nicht durch diesen Spalt weiter nach unten zu den elektronischen Bauteilen vordringen kann. Das Leckageöl wird bei stillstehender oder sich drehender Welle (zentrifugal) in den Ringraum abgeleitet, der über einen vorzugsweise im Gehäuse der Pumpe ausgebildeten Ableitkanal mit einer Ölsammelstelle oder dergleichen verbunden ist. Dank der Schleuderscheibe kann das Hydraulikaggregat somit auch in ungünstigen Einbaulagen verwendet werden. Damit entfallen weitestgehend alle Beschränkungen, die hinsichtlich der Einbaulage bei gebräuchlichen Hydraulikaggregaten bestehen.The drive motor preferably has a housing connection piece on, which is sealingly guided in the pump housing. For the Ventilation of the motor is particularly between the shaft and the housing connector a ventilation gap intended. This annular gap is from the centrifugal disc covered, so that leakage liquid coming from above is not through this gap further down to the electronic Components can penetrate. The leakage oil is at stationary or rotating shaft (centrifugal) in derived the annulus, which is preferably in a Housing of the pump trained discharge channel with a Oil collection point or the like is connected. thanks to the The hydraulic unit can also be used in the centrifugal disc unfavorable installation positions can be used. This eliminates as far as possible all restrictions regarding the Installation position in common hydraulic units exist.

Zweckmäßige Aus- und Weiterbildungen des Erfindungsgedankens sind in den Unteransprüchen beschrieben. Weitere Einzelheiten werden anhand eines in Fig. I dargestellten Ausführungsbeispiels näher erläutert.Appropriate training and further developments of the inventive concept are described in the subclaims. Further details will be explained in more detail using an exemplary embodiment shown in FIG .

Fig. 1 zeigt einen Längsschnitt durch ein erfindungsgemäßes Hydraulikaggregat mit elektronischen Bauteilen, wie beispielsweise einem Motor 1 und/oder einer Einheit 2 zur Regelung eines elektronischen Bremssystems, und einer Pumpe 3. Das obere Ende eines Gehäusestutzens 9 des Antriebsmotors 1 ist unter Zwischenschaltung einer Dichtung 16 in einer Bohrung des Gehäuses der Pumpe 3 angeordnet, wobei zwischen einer Welle 4 des Antriebsmotors 1 und dem Gehäuse der Pumpe 3 in ans ich bekannter Weise ein Lager 5 zur Lagerung der Antriebswelle 4 vorgesehen ist. Der endseitig an der Welle 4 angeordnete Exenter 14 treibt zumindest einen hin- und herbewegbaren Kolben 15 an. In Fig. 1 sind bezüglich des Gravitationsfeldes g sowohl der Motor 1 als auch die Einheit 2, bei der es sich beispielsweise um eine Platine 11 handeln kann, auf der einzelne Elektronikbauteile angeordnet sind, unterhalb der Pumpe 3 angeordnet. Vorzugsweise liegt die Platine 11 über eine Zwischenplatte 12 am Gehäuse der Pumpe 3 an. Die Baueinheit 2 ist vorzugsweise mittels einer Klemmverbindung auf den Gehäusestutzen 9 des Antriebsmotors 1 aufgepreßt oder in ähnlicher Weise befestigt. Fig. 1 shows a longitudinal section through an inventive hydraulic unit with electronic components, such as an engine 1 and / or a unit 2 for controlling an electronic brake system, and a pump 3. The upper end of a housing connector 9 of the drive motor 1 is arranged with the interposition of a seal 16 in a bore of the housing of the pump 3 , a bearing 5 for storing the in a known manner between a shaft 4 of the drive motor 1 and the housing of the pump 3 Drive shaft 4 is provided. The eccentric 14 arranged at the end on the shaft 4 drives at least one reciprocable piston 15 . In Fig. 1 of the gravitational field with respect g both the engine 1 and the unit 2, which may be for example a board 11, are arranged on the individual electronic components, arranged below the pump 3. The circuit board 11 preferably abuts the housing of the pump 3 via an intermediate plate 12 . The assembly 2 is preferably pressed onto the housing connector 9 of the drive motor 1 by means of a clamp connection or fastened in a similar manner.

Die erfindungsgemäßen Mittel zur Ableitung von Leckageflüssigkeit umfassen mit Vorteil wenigstens eine unterhalb des Lagers 5 auf der Welle 4 drehfest angeordnete Schleuderscheibe 6, die im gezeigten Ausführungsbeispiel aus einem ringförmigen Blechteil mit im wesentlichen L-förmigen Querschnitt besteht, wobei ein Schenkel 6a zur Befestigung auf der Welle dient und der anderer Schenkel 6b im wesentlichen radial und dachförmig leicht nach unten verlaufend von der Welle 4 absteht. Konzentrisch zur Schleuderscheibe 6 kann erfindungsgemäß desweiteren ein Ringraum 7 vorgesehen sein, der über einen Ableitkanal 8 mit einer nicht näher bezeichneten Ölsammelstelle verbunden ist. Beispielsweise kann es sich bei der Ölsammelstelle um einen Stopfen handeln, der idealerweise zur Entleerung der Leckageflüssigkeit von Außen zugänglich ist.The means according to the invention for draining leakage liquid advantageously comprise at least one centrifugal disc 6 which is arranged in a rotationally fixed manner underneath the bearing 5 on the shaft 4 and, in the exemplary embodiment shown, consists of an annular sheet metal part with an essentially L-shaped cross section, with one leg 6 a for attachment serves the shaft and the other leg 6 b protrudes essentially radially and roof-shaped slightly downward from the shaft 4 . According to the invention, an annular space 7 can also be provided concentrically to the centrifugal disc 6 , which is connected via a discharge channel 8 to an oil collection point (not specified). For example, the oil collection point can be a stopper that is ideally accessible from the outside for emptying the leakage fluid.

Erfindungsgemäß kann über die Ableitmittel 6, 7, 8 aus einem Pumpenraum 17 durch das Lager 5 hindurchtretende Flüssigkeit oder auch Lagerfett radial bzw. zentrifugal von der Welle 4 weg abgeleitet werden, womit vermieden wird, daß es insbesondere durch den zwischen Welle 4 und Gehäusestutzen 9 vorgesehenen, ringförmigen Be- bzw. Endlüftungsspalt 10 weiter nach unten in die Bereiche vordringen kann, in denen sich gegen Flüssigkeiten empfindliche elektronische Bauteile 1, 2 befinden. Das Lager 5 ist in an sich bekannter Weise mit wenigstens einer Dichtscheibe 13 ausgestattet und einerseits im Preßsitz auf der Welle 4 befestigt und andererseits per Schiebesitz im Gehäuse der Pumpe 3 montiert.According to the invention, liquid or bearing grease that is passing through the bearing 5 from a pump chamber 17 can also be drained radially or centrifugally away from the shaft 4 via the discharge means 6 , 7 , 8 , thereby avoiding the fact that it is caused particularly by the shaft 4 and the housing connector 9 provided annular ventilation or end ventilation gap 10 can penetrate further down into the areas in which there are electronic components 1 , 2 sensitive to liquids.
