Description

Kompressor mit Hydraulikpumpe und Verfahren zur Herstellung eines Kompressors mit Hydraulikpumpe Compressor with hydraulic pump and method for manufacturing a compressor with hydraulic pump
Die Erfindung betrifft ein System mit einem Kompressor und einer Hydraulikpumpe zur Verwendung in einem Nutzfahrzeug, wobei der Kompressor eine Kurbelwelle zum Antrieb des Kompressors umfasst und wobei die Hydraulikpumpe von einer Verlängerung der Kurbelwelle antreibbar ist.The invention relates to a system comprising a compressor and a hydraulic pump for use in a commercial vehicle, the compressor comprising a crankshaft for driving the compressor, and wherein the hydraulic pump is drivable by an extension of the crankshaft.
Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines Systems mit einem Kompressor und einer Hydraulikpumpe zur Verwendung in einem Nutzfahrzeug, wobei der Kompressor eine Kurbelwelle zum Antrieb des Kompressors umfasst, die Hydraulikpumpe von einer Verlan- gerung der Kurbelwelle antreibbar ist und der Kompressor und die Hydraulikpumpe in ein gemeinsames Gehäuse integriert sind.The invention further relates to a method for producing a system with a compressor and a hydraulic pump for use in a commercial vehicle, wherein the compressor comprises a crankshaft for driving the compressor, the hydraulic pump is driven by a request of the crankshaft and the compressor and the hydraulic pump are integrated in a common housing.
Moderne Nutzfahrzeuge weisen viele Teilsysteme auf, die mit Druckluft betrieben werden. Zu ihnen gehört beispielsweise eine druckluftbetriebene Betriebsbremse beziehungsweise eine Luftfederung. Um die Versorgung dieser Teilsysteme mit Druckluft sicherzustellen, ist normalerweise eine Druckluftversorgungseinrichtung in dem Nutz- fahrzeug vorgesehen, die einen Kompressor umfasst. Dieser Kompressor wird mechanisch von dem Verbrennungsmotor des Nutzfahrzeugs angetrieben. Die Kopplung des Kompressors erfolgt dabei üblicherweise über eine Verzahnung an einem Ende der Kurbelwelle des Verbrennungsmotors. Der Kompressor selbst besitzt eine Kurbelwelle, an dessen der Verzahnung abgewandten Seite häufig eine Hydraulikpumpe, zum Beispiel eine Lenkhilfepumpe, angeordnet ist. Der An- schluss der Hydraulikpumpe an die Welle des Kompressors erfolgt beim Stand der Technik mit Hilfe eines Radialspielausgleichlagers, zum Beispiel einem Malteser Kreuz, oder einem Vielzahnlager, welches ein höheres Drehmoment verkraftet jedoch ein geringeres Spiel im Vergleich mit dem Malteser Kreuz toleriert. Das Radialspielausgleichslager ist notwendig, da die Welle mit einem einfachen Gleitlager antriebsseitig in den Kompressor hineingeführt wird, wobei ein recht großes Spiel von bis zu 0,1 mm zugelassen wird.Modern commercial vehicles have many subsystems that are operated with compressed air. These include, for example, an air-operated service brake or air suspension. In order to ensure the supply of compressed air to these subsystems, a compressed air supply device is normally provided in the commercial vehicle, which comprises a compressor. This compressor is mechanically driven by the combustion engine of the commercial vehicle. The coupling of the compressor This is usually done via a toothing at one end of the crankshaft of the engine. The compressor itself has a crankshaft, on the side facing away from the toothing often a hydraulic pump, for example a power steering pump, is arranged. The connection of the hydraulic pump to the shaft of the compressor takes place in the prior art with the aid of a radial play balance bearing, for example a Maltese cross, or a multi-tooth bearing, which tolerates a higher torque but tolerates a lesser clearance compared to the Maltese cross. The radial play compensation bearing is necessary because the shaft is guided into the compressor on the drive side with a simple slide bearing, whereby a fairly large clearance of up to 0.1 mm is permitted.
Nachteilig hierbei ist insbesondere die aufwendige Verbindungskonstruktion zwischen Kompressor und Hydraulikpumpe sowie die notwendigen Abdichtungen zwischen den zwei separaten Gehäusen.The disadvantage here is in particular the complex connection structure between the compressor and hydraulic pump and the necessary seals between the two separate housings.
Der Erfindung liegt die Aufgabe zugrunde, die notwendigen Verbindungskonstruktionen zwischen Kompressor und Hydraulikpumpe zu vereinfachen.The invention has for its object to simplify the necessary connection structures between the compressor and hydraulic pump.
Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst.This object is achieved with the features of the independent claims.
Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben. Die Erfindung baut auf dem gattungsgemäßen System dadurch auf, dass die Kurbelwelle durch ein Kugellager gelagert ist . Durch die Verwendung eines Kugellagers zur Lagerung der Kurbelwelle des Kompressors kann die an den Kompres- sor angeschlossene Hydraulikpumpe vor radialen Kräften geschützt werden. Die Verbindung zwischen der Verlängerung und der Kurbelwelle kann daher ohne konstruktiv aufwendige Verbindungselemente, die ein Radialspiel ermöglichen, durchgeführt werden. Weiterhin kann das der Hydraulikpumpe zugewandte Kompressorlager mit dem dem Kompressor zugewandten Lager der Hydraulikpumpe kombiniert werden, da das zwei separate Lager erfordernde Radialspiel entfällt.Advantageous embodiments of the invention are indicated in the dependent claims. The invention is based on the generic system in that the crankshaft is supported by a ball bearing. By using a ball bearing to support the crankshaft of the compressor, the hydraulic pump connected to the compressor can be protected from radial forces. The connection between the extension and the crankshaft can therefore be carried out without structurally complicated connecting elements which allow a radial clearance. Furthermore, the compressor bearing facing the hydraulic pump can be combined with the compressor facing bearing of the hydraulic pump, since the two separate bearing requiring radial clearance is eliminated.
Insbesondere kann vorgesehen sein, dass die Kurbelwelle und die Verlängerung einstückig gefertigt sind. Eine einstückige Fertigung von Kurbelwelle und Verlängerung stellt sowohl die stabilste als auch die konstruktiv einfachste Möglichkeit zur Verbindung beider Teile dar.In particular, it can be provided that the crankshaft and the extension are made in one piece. A one-piece production of crankshaft and extension represents both the most stable and the structurally simplest way to connect the two parts.
Zusätzlich kann vorgesehen sein, dass der Kompressor und die Hydraulikpumpe in ein gemeinsames Gehäuse integriert sind. Durch die Integration der Hydraulikpumpe in das Kompressorgehäuse können eventuell notwendige Dichtungen zwischen beiden Gehäuseteilen entfallen. Weiterhin kann durch die Integration der Hydraulikpumpe in das Gehäuse des Kompressors die axiale Baulänge des Systems verringert werden.In addition, it can be provided that the compressor and the hydraulic pump are integrated in a common housing. By integrating the hydraulic pump in the compressor housing possibly necessary seals between the two housing parts can be omitted. Furthermore, by integrating the hydraulic pump in the housing of the compressor, the axial length of the system can be reduced.
Nützlicherweise kann dabei vorgesehen sein, dass kühlmittelführende Kanäle vorgesehen sind, die sowohl den Kompressor als auch die Hydraulikpumpe kühlen. Zusätzliche Verbindungselemente zwischen dem Gehäuse des Kompressors und dem Gehäuse der Hydraulikpumpe, die kühlmittelführende Kanäle an dem Gehäuse der Hydraulikpumpe mit kühlmittelführenden Kanälen an dem Gehäuse des Kompressors ver- binden können entfallen, was die Fertigung stark vereinfacht .Usefully, it can be provided that coolant-carrying channels are provided which cool both the compressor and the hydraulic pump. additional Connecting elements between the housing of the compressor and the housing of the hydraulic pump, which can connect coolant-carrying ducts on the housing of the hydraulic pump to coolant-carrying ducts on the housing of the compressor, which greatly simplifies the production.
Vorteilhafterweise kann vorgesehen sein, dass das Kugellager an der der Hydraulikpumpe abgewandten Seite ange- ordnet ist. Die Anordnung des Kugellagers an der der Hydraulikpumpe abgewandten Seite ermöglicht die Montage des Kugellagers nachdem die Kurbelwelle bereits in dem System mit Kompressor und Hydraulikpumpe montiert ist .Advantageously, it can be provided that the ball bearing is arranged on the side facing away from the hydraulic pump. The arrangement of the ball bearing on the side facing away from the hydraulic pump allows the assembly of the ball bearing after the crankshaft is already mounted in the system with compressor and hydraulic pump.
Das gattungsgemäße Verfahren zur Herstellung eines Systems mit einem Kompressor und einer Hydraulikpumpe wird dadurch weitergebildet, dass die Welle von der der Hydraulikpumpe abgewandten Seite in das gemeinsame Gehäuse eingesetzt wird. Durch diese Vorgehensweise kann das gemeinsame Gehäuse auf der Seite der Hydraulikpumpe geschlossen gefertigt werden, weshalb dort keine zusätzlichen Eingriffsmδglichkeiten mit Dichtungen notwendig sind. Auch das so genannte hintere Kompressorlager kann auf diese Weise gemeinsam mit der Welle montiert werden.The generic method for producing a system with a compressor and a hydraulic pump is further developed in that the shaft is inserted from the side facing away from the hydraulic pump in the common housing. By doing so, the common housing can be made closed on the side of the hydraulic pump, which is why there are no additional Eingriffsmδglichkeiten with seals necessary. Also, the so-called rear compressor bearing can be mounted in this way together with the shaft.
Das gattungsgemäße Verfahren kann insbesondere dadurch weiterentwickelt werden, dass ein Kugellager an der der Hydraulikpumpe abgewandten Seite der Kurbelwelle angeordnet wird. Nach dem Einfügen der Kurbelwelle in das ge- meinsame Gehäuse wird kein weiterer Zugriff mehr auf die Kurbelwelle zur Anbringung weiterer Lager benötigt. Weiterhin kann vorgesehen sein, dass kühlmittelführende Kanäle zur Kühlung des Kompressors und der Hydraulikpumpe an dem gemeinsamen Gehäuse angeordnet werden. Gemeinsame kühlmittelführende Kanäle ermöglichen die gleichzeitige Kühlung von Kompressor und Hydraulikpumpe.The generic method can be further developed, in particular, by arranging a ball bearing on the side of the crankshaft facing away from the hydraulic pump. After inserting the crankshaft into the common housing, no further access to the crankshaft is required for mounting additional bearings. Furthermore, it may be provided that coolant-carrying channels for cooling the compressor and the hydraulic pump are arranged on the common housing. Common coolant-carrying channels allow simultaneous cooling of the compressor and hydraulic pump.
Die vorliegende Erfindung wird nun mit Bezug auf die begleitenden Zeichnungen anhand bevorzugter Ausführungsformen beispielhaft erläutert .The present invention will now be described by way of example with reference to the accompanying drawings by way of preferred embodiments.
Es zeigt:It shows:
Figur 1 eine schematische Darstellung eines erfindungs- gemäßen Systems mit Kompressor und Hydraulik- pumpe .Figure 1 is a schematic representation of a system according to the invention with compressor and hydraulic pump.
Figur 1 zeigt eine schematische Darstellung eines erfindungsgemäßen Systems mit Kompressor und Hydraulikpumpe. Ein dargestelltes System 10 mit einem Kompressor 12 und einer Hydraulikpumpe 14 wird von einem Antriebsmotor 28 eines Nutzfahrzeugs 16 angetrieben. Der Kompressor 12 umfasst einen Zylinderkopf 36, einen Kolbenraum 32, Kolben 30, die über Pleuel 34 mit einer Kurbelwelle 18 gekoppelt sind und sich im Inneren des Kolbenraums 32 auf und nieder bewegen. Die Kurbelwelle 18 ist auf der dem Antriebsmotor 28 zugewandten Seite durch ein Kugellager 22 gelagert und auf der dem Antriebsmotor 28 abgewandten Seite durch eine Verlängerung 20 über den eigentlichen Bereich des Kompressors 12 hinaus verlängert . In dem Bereich zwischen der Verlängerung 20 und der Kurbelwelle 18 ist ein Lager 38 angeordnet, das als hinteres Kompressorlager bezeichnet wird. Das Lager 38 kombiniert zwei zuvor in diesem Bereich notwendige Lager miteinander, die beiderseits einer ein Radialspiel ermöglichenden Verbindung zwischen Kurbelwelle 18 und Verlängerung 20 angeordnet waren. Die Verlängerung 20 der Kurbelwelle 18 treibt eine Hydraulikpumpe 14 an, die gemeinsam mit dem Kompressor 12 in einem Gehäuse 24 angeordnet ist. In dem Gehäuse 24 sind weiterhin durchgängige Kühlmittelkanäle 26 angeordnet, über die sowohl der Kompressor 14 als auch die Hydraulikpumpe 14 kühlbar sind.Figure 1 shows a schematic representation of a system according to the invention with compressor and hydraulic pump. An illustrated system 10 with a compressor 12 and a hydraulic pump 14 is driven by a drive motor 28 of a commercial vehicle 16. The compressor 12 includes a cylinder head 36, a piston chamber 32, piston 30, which are coupled via connecting rods 34 with a crankshaft 18 and move up and down in the interior of the piston chamber 32. The crankshaft 18 is mounted on the side facing the drive motor 28 by a ball bearing 22 and extended on the side facing away from the drive motor 28 by an extension 20 over the actual area of the compressor 12 addition. In the area between the extension 20 and the crankshaft 18, a bearing 38 is arranged, which is referred to as a rear compressor bearing. The bearing 38 combines two previously necessary in this area bearing each other, which were arranged on both sides of a radial play enabling connection between the crankshaft 18 and extension 20. The extension 20 of the crankshaft 18 drives a hydraulic pump 14, which is arranged together with the compressor 12 in a housing 24. In the housing 24 continuous coolant channels 26 are further arranged, via which both the compressor 14 and the hydraulic pump 14 can be cooled.
Bei der Montage der Kurbelwelle 18 wird zunächst die Kurbelwelle 18 und das Lager 38 von der der Hydraulikpum- pe 14 abgewandten Seite in das Gehäuse 24 eingebracht und anschließend das Kugellager 22 zur Lagerung der Kurbel- welle 18 auf der der Hydraulikpumpe abgewandten Seite montiert. Dies bringt keine weiteren Nachteile mit sich, da sowohl Kompressor als auch Hydraulikpumpe üblicherweise eine Standzeit aufweisen, die mit der Fahrzeuglebensdauer zumindest identisch ist .When mounting the crankshaft 18, the crankshaft 18 and the bearing 38 are first introduced into the housing 24 from the side facing away from the hydraulic pump 14, and then the ball bearing 22 is mounted on the side facing away from the hydraulic pump for supporting the crankshaft 18. This brings no further disadvantages, since both compressor and hydraulic pump usually have a life that is at least identical to the vehicle life.
