Description
Die Erfindung betrifft ein hydraulisches Kombinationsaggregat, umfassend einen Tank, eine Pumpenanordnung, hydraulische Steuerelemente, und einen Elektromotor für die Pumpenanordnung, welche Bauteile koaxial entlang einer geraden Achse angeordnet sind, allenfalls einander teilweise überlappend.The invention relates to a hydraulic combination unit, comprising a tank, a pump assembly, hydraulic controls, and an electric motor for the pump assembly, which components are arranged coaxially along a straight axis, at most partially overlapping each other.
Die EP 1 302 660 A2 offenbart eine als Axialkolbenpumpe ausgeführte Kraftstoffpumpe, die in einem Kraftstofftank eines Fahrzeuges eingesetzt ist. Der Motor für die Pumpenanordnung ist koaxial mit dieser Pumpenanordnung ausgeführt, die Pumpe selbst ist aber als Einheit im viel größeren Kraftstofftank eingebaut, auch ohne speziell auf eine besondere geometrische Konstellation einzugehen, wie sie beispielsweise für hydraulische Kombinationsaggregate wesentlich ist. Diese wie eingangs erwähnt aufgebauten und mit Ausnahme der Stromversorgung für den Elektromotor autarken Aggregate sind an sich bekannt und werden in steigendem Ausmaß für transportable Anwendungen und/oder für kleine aufzubringende Kräfte eingesetzt, beispielsweise im Zusammenhang mit der hydraulischen Betätigung von Fahrzeugverdecken, aber auch der Verstellung von medizinischen Behandlungsstühlen od. dgl.EP 1 302 660 A2 discloses a fuel pump designed as an axial piston pump, which is inserted in a fuel tank of a vehicle. The motor for the pump assembly is designed coaxially with this pump assembly, but the pump itself is incorporated as a unit in the much larger fuel tank, even without specifically entering into a particular geometrical constellation, as it is essential for hydraulic combination aggregates. These as mentioned above built and self-sufficient with the exception of the power supply for the electric motor units are known and used to an increasing extent for portable applications and / or small applied forces, for example in connection with the hydraulic actuation of vehicle concealment, but also the adjustment od medical treatment chairs. Like.
So ist etwa aus der DE-C3 32 27 926 bekannt, auf einer Seite eines Basisteils eine druckentlastete Zahnradpumpe und den Tank und auf der anderen Seite den abgedichtet gekapselten Motor für die Pumpe anzuordnen. Durch eine Verbindungsöffnung im Basisteil kann auch der im Motorgehäuse verbleibende Innenraum als Tankvolumen genutzt werden.For example, from DE-C3 32 27 926 known to arrange on one side of a base part a pressure-relieved gear pump and the tank and on the other side of the sealed motor encapsulated for the pump. Through a connection opening in the base part and the remaining space in the motor housing interior can be used as a tank volume.
Weiters ist aus der EP-A1 0 628 720 ein Kombinationsaggregat bekannt, bei dem an den Basisteil mit einer Radialkolbenpumpe in axialer Richtung anschließend zuerst ein rohrförmiger Tank für das Hydraulikmedium und daran anschließend koaxial der Elektromotor als Pumpenantrieb angeordnet sind, wobei die Motorwelle abgedichtet in den Tank eintritt und durch diesen hindurch zur Pumpe reicht. Dabei muß auch der Tank relativ steif und damit schwer ausgeführt sein. Ein Aggregat, bei welchem der Motor in den koaxial angeordneten Tank hineinragt, ist in der EP-A1 0 690 230 geoffenbart, und ein Kombinationsaggregat, ebenfalls mit Radialkolbenpumpe, mit den rohrförmig gekapselten Elektromotor der Pumpe ringförmig umgebendem Tank zeigt die EP-A1 0 857 871.Furthermore, from EP-A1 0 628 720 a combination unit is known in which the tubular body with a radial piston pump in the axial direction then first a tubular tank for the hydraulic medium and then coaxially the electric motor are arranged as a pump drive, the motor shaft sealed in the Tank enters and passes through this to the pump. The tank must also be relatively stiff and therefore heavy. An assembly in which the engine protrudes into the coaxially arranged tank is disclosed in EP-A1 0 690 230, and a combination unit, also with radial piston pump, annularly surrounding the pump with the tubular encapsulated electric motor of the pump shows EP-A1 0 857 871st
Die Aufgabe der vorliegenden Erfindung war ein Kombinationsaggregat mit weiter verkleinerten Abmessungen und einfacherem Aufbau. Durch höheren Integrationsgrad soll auch die Wirtschaftlichkeit bei der Herstellung erhöht und damit eine Kostensenkung erzielt werden.The object of the present invention was a combination unit with further reduced dimensions and simpler structure. The higher degree of integration should also increase the profitability of production and thus reduce costs.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Pumpenanordnung durch eine Axialkolbenpumpe gebildet ist, deren mit mehreren Pumpenelementen versehener Zylinderblock koaxial zu den anderen Bauteilen orientiert ist. Damit kann die durch den Tank ohnedies notwendige axiale Länge des Kombinationsaggregates optimal ausgenutzt werden, wobei der Durchmesser aber gegenüber anderen Pumpenausführungen wesentlich geringer gehalten werden kann, insbesonders im Vergleich zu Zahnradpumpen oder den meist in derartigen Aggregaten verwendeten Radialkolbenpumpen.To achieve this object, the invention provides that the pump assembly is formed by an axial piston pump whose cylinder block provided with a plurality of pump elements is oriented coaxially with the other components. Thus, the required by the tank anyway axial length of the Combination aggregates are optimally utilized, the diameter but can be kept substantially lower compared to other pump designs, especially in comparison to gear pumps or the radial piston pumps usually used in such aggregates.
Eine weitere Verkleinerung bzw. optimale Ausnutzung des vorhandenen Bauvolumens ist gemäß einer bevorzugten Ausführungsvariante möglich, gemäß welcher der Zylinderblock entlang seines Umfangs mit Magneten versehen und als Rotor des Elektromotors ausgeführt ist. Ein von der Pumpe separater Motor kann somit vermieden und dessen Bauvolumen eingespart werden.A further reduction or optimal utilization of the existing construction volume is possible according to a preferred embodiment, according to which the cylinder block is provided along its circumference with magnets and designed as a rotor of the electric motor. A separate from the pump motor can thus be avoided and its construction volume can be saved.
Vorteilhafterweise sind dabei die Magnetspulen des Elektromotors im Gehäuse des Kombinationsaggregates um den Zylinderblock herum angeordnet.Advantageously, the magnetic coils of the electric motor in the housing of the combination unit are arranged around the cylinder block around.
Die Leitungsführung und Ausführung der hydraulischen Elemente kann dadurch vereinfacht werden, daß der Tank und der Zylinderblock in Bezug auf den Bereich der hydraulischen Steuerelemente auf der gleichen Seite, vorzugsweise im wesentlichen koaxial zueinander, angeordnet sind.The routing and design of the hydraulic elements can be simplified by arranging the tank and cylinder block in relation to the area of the hydraulic controls on the same side, preferably substantially coaxial with each other.
Eine weitere Vereinfachung der hydraulischen Leitungsführung ist durch das Erfindungsmerkmal möglich, gemäß welchem der Zylinderblock auf einem Rohr drehbar gelagert ist, welches Rohr vom Bereich der hydraulischen Steuerelemente ausgeht und mit einer Ansaugöffnung in den Tank des Kombinationsaggregates reicht.A further simplification of the hydraulic line guide is possible by the feature of the invention, according to which the cylinder block is rotatably mounted on a tube, which pipe from the area of the hydraulic controls emanates and extends with a suction in the tank of the combination aggregate.
Vorteilhafterweise sind der Tank und der Bereich des Gehäuses des Kombinationsaggregates, in welchem sich der Zylinderblock befindet, durch eine Trennwand getrennt. Damit kann die Ansaugöffnung für die Hydraulikflüssigkeit in einen Bereich verlegt werden, der durch die schnell drehende Axialkolbenpumpe nicht verwirbelt bzw. verschäumt werden kann.Advantageously, the tank and the region of the housing of the combination aggregate, in which the cylinder block is located, are separated by a partition wall. Thus, the suction opening for the hydraulic fluid can be moved into an area that can not be swirled or foamed by the rapidly rotating axial piston pump.
Wenn dabei vorteilhafterweise das Rohr in der Trennwand gelagert ist, kann damit eine stabilere Lagerung für den Zylinderblock der Pumpe sichergestellt werden, welche gleichzeitig ja auch der Rotor des Elektromotors ist.If this advantageously the tube is mounted in the partition, so that a more stable storage for the cylinder block of the pump can be ensured, which is also the rotor of the electric motor yes at the same time.
Die bekannten Vorteile eines normalerweise komplizierten Unterölmotors können beim erfindungsgemäßen Kombinationsaggregat einfacher dadurch erzielt werden, daß in der Trennwand zumindest eine Öffnung unterhalb des Flüssigkeitsniveaus und zumindest eine Öffnung oberhalb des Flüssigkeitsniveaus, jeweils bei normaler Betriebslage des Kombinationsaggregates, vorgesehen ist, durch welche Öffnungen der Tank mit dem Bereich des Gehäuses, in welchem sich der Zylinderblock befindet, in Verbindung steht. Damit kann ein Motor mit hoher Leistung bei kleiner Baugröße zur Anwendung kommen, da die Wärme über das den Motor bzw. den Zylinderblock umspülende Hydraulikmedium abtransportiert wird.The well-known advantages of a normally complicated sub-oil engine can be achieved in the combination unit according to the invention by providing in the partition at least one opening below the liquid level and at least one opening above the liquid level, each at normal operating position of the combination aggregate, through which openings the tank with the area of the housing in which the cylinder block is in communication. Thus, a motor with high performance in a small size can be used, since the heat is removed via the motor or the cylinder block flushing hydraulic medium.
Die gleichen Vorteile lassen sich bei einer alternativen erfindungsgemäßen Ausführungsform erzielen, bei der der Bereich des Gehäuses, in welchem sich der Zylinderblock befindet, gleichzeitig der Tank ist.The same advantages can be achieved in an alternative embodiment according to the invention, in which the area of the housing in which the cylinder block is located is at the same time the tank.
Eine weitere Verbesserung der obigen Konstruktion sieht vor, daß zumindest einige der Magnetspulen von der Flüssigkeit bedeckt oder umströmt sind. Damit ist auch die Verlustleistung der Wicklungen einfach über das Hydraulikmedium abzuführen, so daß hohe Stromstärken und damit große Motorleistungen bei geringer Baugröße möglich sind.A further improvement of the above construction provides that at least some of the magnetic coils are covered or flowed around by the liquid. Thus, the power loss of the windings is easy to dissipate via the hydraulic medium, so that high currents and thus large engine power with a small size are possible.
Die oben genannten Vorteile kommen insbesonders dann zur Geltung, wenn in normaler Betriebslage des Kombinationsaggregates der Flüssigkeitsstand im Tank so hoch ist, daß zumindest der Zylinderblock und/oder die Wicklungen zu zumindest einem Großteil von der Flüssigkeit bedeckt ist/sind.The abovementioned advantages are particularly effective when, in the normal operating position of the combination aggregate, the liquid level in the tank is so high that at least the cylinder block and / or the windings are at least substantially covered by the liquid.
Im Sinn der einfachen Bauweise des erfindungsgemäßen Kombinationsaggregat kann gemäß einem weiteren Erfindungsmerkmal noch vorgesehen sein, daß die Taumelscheibe auf dem Rohr gelagert ist.In the sense of simple construction of the combination unit according to the invention can still be provided according to a further feature of the invention that the swash plate is mounted on the tube.
In der nachfolgenden Beschreibung soll ein Ausführungsbeispiel der Erfindung anhand der beigefügten Zeichnungen näher erläutert werden.In the following description, an embodiment of the invention will be explained in more detail with reference to the accompanying drawings.
Dabei zeigt die Fig. 1 einen axialen Längsschnitt durch ein Kombinationsaggregat gemäß der vorliegenden Erfindung und Fig. 2 ist ein Querschnitt durch das Kombinationsaggregat der Fig. 1 entlang der Linie II-II.1 shows an axial longitudinal section through a combination aggregate according to the present invention, and FIG. 2 is a cross-section through the combination aggregate of FIG. 1 along the line II-II.
Das hydraulische Kombinationsaggregat der Fig. 1 weist einen Bereich 1 für die hydraulischen Steuerelemente auf, welcher einerseits den Boden des Aggregates bildet und in bekannter Weise auch nierenförmige Steueröffnungen für die daran anschließende, vorzugsweise reversierbare Axialkolbenpumpe aufweist. Der Zylinderblock 2 der Axialkolbenpumpe wird mit einer seiner Stirnseiten, auf welcher die Ein- bzw. Auslässe der Zylinder 2a vorgesehen sind, in koaxialer Anordnung an den Bereich 1 angedrückt. Der Zylinderblock 2 ist dabei drehbar auf einem hohlen Rohr 3 gelagert, welches Rohr 3 vom Bereich 1 der hydraulischen Steuerelemente ausgeht und mit einer Ansaugöffnung 3a in den Tank 4, 4a ragt. Auf diesem hohlen Rohr 3 ist vorteilhafterweise koaxial zum Bereich 1 und dem Zylinderblock 2 auch die Taumelscheibe 5 drehfest gelagert, welche durch ihre gegenüber der Stirnseite des Zylinderblocks 2 geneigte Vorderseite die axiale Bewegung der in den Zylindern 2a geführten Kolben 6 der Axialkolbenpumpe bewirkt.The hydraulic combination unit of FIG. 1 has a region 1 for the hydraulic control elements, which on the one hand forms the bottom of the unit and in a known manner also has kidney-shaped control openings for the adjoining, preferably reversible axial piston pump. The
Im Zylinderblock 2 der Axialkolbenpumpe sind vier Magnete 7 vorgesehen, so daß dieser Zylinderblock 2 gleichzeitig der Rotor eines bürstenlosen Elektromotors ist. Die entsprechenden Wicklungen der Magnetspulen 8 sind um den Zylinderblock 2 herum innerhalb des Gehäuses 9 des Kombinationsaggregates angeordnet. Es ist somit kein separater Elektromotor für die Axialkolbenpumpe notwendig, sondern sie selbst ist, zusammen mit den Magnetspulen 8, ihr eigener Motor.In the
Vorteilhafterweise sind die Magnetspulen 8 und die Taumelscheibe 5 mit dem Bereich 1 der hydraulischen Steuerelemente durch eine gemeinsame Trägerstruktur 18 zu einer Einheit verbunden. Damit kann das Gehäuse 9 des Kombinationsaggregates dünner und leichter ausgeführt sein, weil die mechanische Festigkeit zu einem großen Anteil durch diese Trägerstruktur 18 bewirkt wird.Advantageously, the
Bei der dargestellten Ausführungsform des Kombinationsaggregates ist der Bereich 4a der Axialkolbenpumpe 2, 2a, 5, 6 durch eine Trennwand 10 von dem Bereich 4 des Tanks getrennt, in welchen die Ansaugöffnung 3a des Rohrs 3 hineinragt. In dieser Trennwand 10 sind Löcher 11 oder ähnliche durchgehende Öffnungen vorgesehen, durch welche der Bereich 4a mit der Axialkolbenpumpe und der Bereich 4 miteinander in Verbindung stehen, so daß sich in beiden Bereichen Hydraulikflüssigkeit bis zu einem Flüssigkeitsniveau 12 befindet. Das Niveau 12 der Hydraulikflüssigkeit ist so hoch, daß sich zumindest eines der Löcher 11a im lufterfüllten Bereich des Tanks 4, 4a befindet.In the illustrated embodiment of the combination aggregate, the
Auf der der Axialkolbenpumpe 2, 2a, 5, 6 gegenüberliegenden Seite des Tanks 4, 4a, welcher ebenfalls koaxial zum Bereich 1 und dem Zylinderblock 2 angeordnet ist, ist zwischen einer weiteren Trennwand 13 und dem Deckel 14 des Kombinationsaggregates eine Platine 15 mit der Steuerelektronik eingesetzt, welche auch über die Leitungen die Ansteuerung der Wicklungen 8 übernimmt. Die Stromversorgung und allfällige Steuersignale werden über den Zentralanschluß 17 bewerkstelligt bzw. zugeführt.On the
