Description

Die Erfindung betrifft eine gasdynamische Druckwellenmaschine zur Aufladung einer Verbrennungskraftmaschine, mit einem in einem Gehäuse auf einer Welle drehbar gelagerten Zellenrotor, der zwischen einer Zuleitung für Ladeluft und einer Abgasleitung für Verbrennungsgase angeordnet ist, nach dem Oberbegriff von Anspruch 1.The invention relates to a gas-dynamic pressure wave machine for charging an internal combustion engine, having a cell rotor rotatably mounted in a housing on a shaft, which is arranged between a feed line for charge air and an exhaust gas line for combustion gases, according to the preamble of claim 1.

Aufladesysteme, die gasdynamische Prozesse in geschlossenen Gaskanälen erzeugen und zur Aufladung nutzen, werden im Allgemeinen als Druckwellenlader oder Druckwellenmaschinen bezeichnet. Die Zellenrotoren sind zylindrisch gestaltet und besitzen zumeist axial gerade, querschnittskonstant verlaufende Kanäle, die sich von der Heißgas- zur Kaltgasseite erstrecken. Einen aus Blechteilen aufgebauten Zellenrotor mit nicht-zylindrischer Außenkontur zeigt die DE 10 2007 021 367 A1 . Das tragende Innensystem des Zellenrotors als Welle-Nabe-Verbindung kann durch spanende Fertigung hergestellt werden. Es handelt sich hierbei um eine Welle mit entsprechenden Lagerungsmitteln, an der auch entsprechende Abdichtmittel vorgesehen sind. Die Welle trägt dabei eine kegelstumpfförmige Nabe, an welcher eine Zellenstruktur des Zellenrotors befestigt ist.Charging systems that generate gas-dynamic processes in closed gas channels and use them for charging are generally referred to as pressure wave superchargers or pressure wave machines. The cell rotors are cylindrical and usually have axially straight, cross-section constant running channels extending from the hot gas to the cold gas side. A constructed of sheet metal cell rotor with non-cylindrical outer contour shows the DE 10 2007 021 367 A1 , The supporting inner system of the cell rotor as a shaft-hub connection can be made by machining. It is a wave with corresponding storage means on which appropriate sealing means are provided. The shaft carries a frusto-conical hub, to which a cell structure of the cell rotor is attached.

Die GB 920, 624 zeigt ebenfalls einen aus Blech gebauten Zellenrotor aus einem inneren und einem äußeren Zylinder und Zwischenwänden, die sich zwischen den beiden Zylindern erstrecken und die sich in Form eines Z, eines Us oder eines Is jeweils gegenseitig berühren. Sowohl der innere als auch der äußere Zylinder sind dadurch hergestellt, dass ein Blech zu einem Zylinder entsprechender Größe zusammengerollt und dann Längsnaht geschweißt wird. Die eigentliche Welle-Nabe-Verbindung, um die der Zellenrotor rotiert, ist nicht weiter dargestellt.The GB 920, 624 also shows a built of sheet metal cell rotor of an inner and an outer cylinder and partitions that extend between the two cylinders and each touching each other in the form of a Z, a Us or an Is. Both the inner and outer cylinders are made by rolling a sheet into a cylinder of appropriate size and then welding it longitudinally. The actual shaft-hub connection about which the cell rotor rotates is not shown.

Aus der DE 10 2007 037 424 A1 ist eine gasdynamische Druckwellenmaschine zur Aufladung einer Verbrennungskraftmaschine bekannt, welche einen in einem Gehäuse auf einer Welle drehbar gelagerten Zellenrotor aufweist. Der Zellenrotor ist zwischen einer Leitung für Ladeluft und einer Abgasleitung für Verbrennungsgase angeordnet. Dabei ist die Welle in einem Rohr aus Blech als Nabenaußenkörper aufgenommen, wobei die Bohrung für die Wellenaufnahme in einer in dem Nabenaußenkörper befestigten Scheibe ausgebildet ist.From the DE 10 2007 037 424 A1 a gas-dynamic pressure wave machine for charging an internal combustion engine is known, which has a rotatably mounted in a housing on a shaft cell rotor. The cell rotor is disposed between a charge air duct and an exhaust duct for combustion gases. In this case, the shaft is received in a tube made of sheet metal as the hub outer body, wherein the bore for the shaft receiving is formed in a fixed in the hub outer body disc.

Aus der WO 97/20134 A1 geht ebenfalls eine Aufladeeinrichtung für die Ladeluft einer Verbrennungskraftmaschine hervor, deren Zellenrotor um einen Nabenaußenkörper aus Blech in Form eines Rohres angeordnet ist, wobei der Nabenaußenkörper eine innere Scheibe aufweist, welche über eine entsprechende Bohrung den Zellenrotor mit der Welle verbindet.From the WO 97/20134 A1 also shows a charging device for the charge air of an internal combustion engine, the cell rotor is arranged around a hub outer body made of sheet metal in the form of a tube, the hub outer body having an inner disc which connects the cell rotor with the shaft via a corresponding bore.

Problematisch an heutigen Systemen ist das thermische Belastungskollektiv, dem die gesamte Bauteilgeometrie des Zellenrotors unterliegt. So finden sich auf der Heißgasseite des Zellenrotors Temperaturen von bis zu 1.100° C und auf der Kaltgasseite Temperaturen von maximal 200° C. Ein thermisch verursachter Bauteilverzug und ein daraus resultierender suboptimaler Wirkungsgrad sind die Folge. Probleme treten insbesondere bei der Spaltmaßhaltigkeit zwischen den Gas führenden Elementen auf. Üblicherweise wurden daher die bei Druckwellenmaschinen bisher in der Serienproduktion für Automobile zum Einsatz gekommenen Zellenrotoren aus gegossenem Material hergestellt. Da eine gegossene Druckwellenmaschine aber relativ teuer und schwer ausfällt, gehen die Bestrebungen vermehrt in Richtung eines aus Blech gebauten Rotors. Die Welle-Nabe-Verbindung inklusive einem die Verbindung aufnehmenden Nabenaußenkörper verblieben bisher aufgrund der Bauteilkomplexität jedoch als Gussteil. Allerdings ist es aufgrund der anisotrophen thermischen Belastung problematisch, unterschiedliche Werkstoffe für die Zellenstruktur des Rotors und die Nabe zu wählen. Außerdem ergibt sich durch die bisher verwendeten hochtemperaturfesten Werkstoffe eine aufwändige, langsame Bearbeitung zum Fertigmaß.The problem with today's systems is the thermal load collective, which is subject to the entire component geometry of the cell rotor. For example, temperatures of up to 1,100 ° C can be found on the hot gas side of the cell rotor and temperatures of up to 200 ° C on the cold gas side. A thermally induced component distortion and the resulting suboptimal efficiency are the result. Problems occur especially in the Gap accuracy between the gas-conducting elements. Usually, therefore, the cell rotors used in pressure wave machines in series production for automobiles have been manufactured from cast material. However, as a cast blast machine is relatively expensive and heavy, the efforts are increasingly towards a sheet metal rotor. However, the shaft-hub connection, including a hub outer body receiving the connection, has remained as a casting due to component complexity. However, due to the anisotropic thermal stress, it is problematic to choose different materials for the cell structure of the rotor and the hub. In addition, results from the high-temperature resistant materials used so far a complex, slow processing to finished size.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine verbesserte gasdynamische Druckwellenmaschine mit einer leichteren und mit geringerem Fertigungsaufwand herstellbaren Welle-Nabe-Verbindung aufzuzeigen.It is therefore the object of the present invention to provide an improved gas-dynamic pressure wave machine with a lighter and producible with less manufacturing effort shaft-hub connection.

Diese Aufgabe löst die Erfindung, indem bei einer gasdynamischen Druckwellenmaschine zur Aufladung einer Verbrennungskraftmaschine, mit einem in einem Gehäuse auf einer Welle drehbar gelagerten Zellenrotor, der zwischen einer Zuleitung für Ladeluft und einer Abgasleitung für Verbrennungsgase angeordnet ist. Die Welle ist in einem Rohr aus Blech als Nabenaußenkörper aufgenommen,wobei in dem Nabenaußenkörper ein Stück Rohr kleineren Durchmessers als das Rohr des Nabenaußenkörpers befestigt ist, welches die Welle aufnimmt. Der Nabenaußenkörper kann dabei entsprechend dem Zellenrotor aus einem höherwertigen Blechmaterial bestehen. Das Innenleben des Nabenaußenkörpers ermöglicht dann einen neuen Freiheitsgrad in Bezug auf die Werkstoffauswahl.This object is achieved by the invention in that in a gas-dynamic pressure wave machine for charging an internal combustion engine, with a rotatably mounted in a housing on a shaft cell rotor, which is arranged between a feed line for charge air and an exhaust pipe for combustion gases. The shaft is received in a tube of sheet metal as the hub outer body, wherein in the hub outer body, a smaller diameter pipe is attached as the tube of the hub outer body which receives the shaft. The hub outer body may consist of a higher quality sheet material corresponding to the cell rotor. The interior of the hub outer body then allows a new degree of freedom in terms of material selection.

Die gesamte Nabe ist aus Blechteilen gebaut. Dazu wird ein inneres Rohr kleineren Durchmessers als der Nabenaußenkörper eingesetzt, um die Welle aufzunehmen. Dieses innere Rohr kleineren Durchmessers wird dann mittels separater Blechteile im Nabenaußenkörpers radial gehaltert. Das die Welle aufnehmende innere Rohr erstreckt sich dabei nur über eine Teillänge des äußeren Nabenkörpers. Es ist ausreichend dickwandig, um den Belastungen standzuhalten. Die Blechteile können im Nabenaußenkörper in einem Winkel zur Querschnittsebene des Nabenaußenkörpers angebracht werden. Die Blechteile sind konvex oder konkav zueinander gekrümmt sein, um Spannungen, Fertigungstoleranzen und/oder Wärmeverzug auszugleichen. Um einen sicheren Sitz des inneren Rohres zu gewährleisten, sind mehrere Blechteile zwischen innerem Rohr und Nabenaußenkörper vorgesehen, die voneinander beabstandet sind. Die innere Wandung des Nabenaußenkörpers kann in der Kontur bearbeitet sein, um einen Passsitz einzelner Teile zu gewährleisten oder Toleranzen auszugleichen. Bevorzugt sind in den Nabenaußenkörper mit Abstand zur Wellenaufnahme ein oder mehrere Hitzeschilde eingebracht, die die empfindlichen Lager der Welle vor den bis zu 950° C heißen Abgastemperaturen schützen.The entire hub is made of sheet metal parts. For this purpose, an inner tube smaller diameter than the hub outer body is used to receive the shaft. This inner tube of smaller diameter is then radially supported by means of separate sheet metal parts in the hub outer body. That's the wave receiving inner tube extends only over a partial length of the outer hub body. It is sufficiently thick-walled to withstand the stresses. The sheet metal parts may be mounted in the hub outer body at an angle to the cross-sectional plane of the hub outer body. The sheet metal parts are convex or concave curved to each other to compensate for stresses, manufacturing tolerances and / or heat distortion. In order to ensure a secure fit of the inner tube, a plurality of sheet metal parts between inner tube and hub outer body are provided, which are spaced apart. The inner wall of the hub outer body can be machined in the contour to ensure a snug fit of individual parts or to compensate for tolerances. Preferably, one or more heat shields are introduced into the hub outer body at a distance from the shaft holder, which protect the sensitive bearings of the shaft against the exhaust gas temperatures of up to 950 ° C.

Nachfolgend ist die Erfindung anhand der Figuren näher erläutert. Dabei zeigen:

The invention is explained in more detail below with reference to the figures. Showing:

FIG. 2

FIG. 3
a longitudinal section through a pressure wave supercharger in the shaft-hub connection. The hub is not designed according to the invention.

Figur 1 zeigt eine erfindungsgemäße Nabe 1 ohne Welle im Längsschnitt. Die Nabe 1 weist einen zylindrischen Nabenaußenkörper 2 auf, in dem ein inneres Rohr 3 über konvex zueinander angeordnete Blechteile 4a, 4b gehaltert ist. Die Blechteile 4a, 4b schließen hierbei eine im Wesentlichen bikonvexe Form zwischen sich ein. Die Blechteile 4a, 4b verlaufen folglich nicht parallel zu einer Querschnittsebene A-A. Damit sich die zwischen den Blechteilen 4a, 4b eingeschlossene Luft unter thermischer Belastung ausdehnen kann, sind in den Blechteilen 4a, 4b nicht näher dargestellte Ausnehmung für einen Gasaustausch vorgesehen. FIG. 1 shows a hub 1 according to the invention without a shaft in longitudinal section. The hub 1 has a cylindrical hub outer body 2, in which an inner tube 3 via convexly arranged sheet metal parts 4a, 4b is supported. The sheet metal parts 4a, 4b in this case enclose a substantially biconvex shape between them. The sheet metal parts 4a, 4b consequently do not run parallel to a cross-sectional plane AA. Thus, the trapped between the sheet metal parts 4a, 4b air can expand under thermal stress, are in the Sheet metal parts 4a, 4b not shown recess provided for a gas exchange.

Figur 2 zeigt einen ähnlichen Aufbau, allerdings ist hier das innere Rohr 3 über eine bikonkave Form zwischen sich einschließende Blechteile 5a, 5b im Nabenaußenkörper 2 festgelegt. Die Blechteile 5a, 5b sind somit konkav zueinander geformt. Der Nabenaußenkörper 2 besteht aus einem aus Blech gezogenen oder geschweißten Rohr, gleiches gilt für das innere Rohr 3. Das innere Rohr 3 dient zur Aufnahme der nicht gezeigten Welle. In einem Bereich 20, 21 sind die möglichen Konturen einer Bearbeitung der Innenwand des Nabenaußenkörpers 2 dargestellt. Durch den erfindungsgemäßen Konstruktionsaufbau können Nabenaußenkörper 2, inneres Rohr 3 und Blechteile 4a, 4b, 5a, 5b verschiedene Materialien aufweisen. Die Nabe 1 wird insgesamt leichter und flexibler herstellbar. FIG. 2 shows a similar structure, but here is the inner tube 3 via a biconcave shape between them enclosing sheet metal parts 5a, 5b set in the hub outer body 2. The sheet metal parts 5a, 5b are thus formed concave to each other. The hub outer body 2 consists of a drawn or welded sheet metal tube, the same applies to the inner tube 3. The inner tube 3 serves to receive the shaft, not shown. In a region 20, 21, the possible contours of a processing of the inner wall of the hub outer body 2 are shown. As a result of the construction according to the invention, hub outer body 2, inner tube 3 and sheet metal parts 4a, 4b, 5a, 5b can have different materials. The hub 1 is overall easier and more flexible to produce.

Figur 3 zeigt eine Druckwellenmaschine 6 im Längsschnitt. Die Druckwellenmaschine 6 weist einen Zellenrotor 7 auf, welcher aus zwei Reihen 7a, 7b von Zellen besteht, die durch ein Blech 7c voneinander getrennt sind. Die Reihen 7a, 7b des Zellenrotors 7 sind um einen zylindrischen Nabenaußenkörper 71 herum angeordnet. Der Zellenrotor 7 ist mit dem Nabenaußenkörper 71 verbunden und über dessen Verbindung zu einer Welle 13 drehbar gelagert. Der Zellenrotor 7 ist von einem feststehenden doppelwandigen Gehäuse 8 umgeben, welches über eine Gehäuseanbindung 9 mit einer nicht näher dargestellten Heißgasseite B verbindbar ist. Auf einer der Heißgasseite B gegenüberliegenden Kaltgasseite C ist der Zellenrotor 7 mit einem Ansaugtrakt 10 und einer Ladeluftleitung 11 verbunden. Sowohl Ansaugtrakt 10 als auch Ladeluftleitung 11 befinden sich in einem gemeinsamen Gussgehäuse 12. FIG. 3 shows a pressure wave machine 6 in longitudinal section. The pressure wave machine 6 has a cell rotor 7, which consists of two rows 7a, 7b of cells which are separated from each other by a plate 7c. The rows 7a, 7b of the cell rotor 7 are arranged around a cylindrical hub outer body 71 around. The cell rotor 7 is connected to the hub outer body 71 and rotatably supported via the connection thereof to a shaft 13. The cell rotor 7 is surrounded by a fixed double-walled housing 8, which is connectable via a housing connection 9 with a hot gas side B, not shown. On one of the hot gas side B opposite cold gas side C of the cell rotor 7 is connected to an intake manifold 10 and a charge air line 11. Both intake tract 10 and charge air line 11 are located in a common casting housing 12.

In dem Gussgehäuse 12 ist die Welle 13 über Kugellager 14 drehbar gelagert. An ihrem dem Zellenrotor 7 abgewandten Ende wird die Welle 13 an einem nicht näher dargestellten Antriebsmotor befestigt. Die Kugellager 14 sind über Deckel und Dichtungen 15a, 15b gegen Verschmutzungen geschützt.In the cast housing 12, the shaft 13 is rotatably supported by ball bearings 14. At its end facing away from the cell rotor 7, the shaft 13 is attached to a drive motor, not shown. The ball bearings 14 are protected by cover and seals 15a, 15b against contamination.

Erfindungsgemäß besteht der Nabenaußenkörper 71 als inneres Rohr des Zellenrotors 7 aus einem nahtlos gezogenen oder geschweißten Rohr. Die Innenwand des Nabenaußenkörpers 71 weist eine bearbeitete Kontur 72 auf, um einen Passsitz für drei hintereinander liegende Hitzeschilde 16 zu schaffen, welche mittels einer Schraube 17 miteinander verbunden sind. Die Hitzeschilde 16 trennen die Heißgasseite B von der Kaltgasseite C im Inneren des Nabenaußenkörpers 71. Damit sich die zwischen den drei Hitzeschilden 16 eingeschlossene Luft unter thermischer Belastung ausdehnen kann, sind die beiden der Kaltgasseite C zugewandten Hitzeschilde 16 mit einer nicht näher dargestellten Ausnehmung für einen Gasaustausch versehen. Der erste der Hitzeschilde 16, welcher der Heißgasseite B zugewandt ist, weist eine gasdichte Ausführung auf.According to the invention, the hub outer body 71 as the inner tube of the cell rotor 7 consists of a seamlessly drawn or welded tube. The inner wall of the hub outer body 71 has a machined contour 72 in order to provide a snug fit for three consecutive heat shields 16, which are connected to one another by means of a screw 17. The heat shields 16 separate the hot gas side B from the cold gas side C inside the hub outer body 71. Thus, the trapped between the three heat shields 16 air can expand under thermal load, the two of the cold gas side C facing heat shields 16 with a recess, not shown for a Gas exchange provided. The first of the heat shields 16, which faces the hot gas side B, has a gas-tight construction.

Weiterhin ist in dem Nabenaußenkörper 71 eine bearbeitete Kontur 73 vorgesehen, in der das Gussgehäuse 12 mit genügend Spiel für eine ungehinderte Drehbarkeit des Zellenrotors 7 eingeschoben ist. Die Welle 13 ist nicht erfindungsgemäß in eine Scheibe 18 in Form eines gegossenen Felgensterns eingesteckt und über eine Schraube 19 mit der Scheibe 18 verschraubt. Die Scheibe 18 ist mit dem Nabenaußenkörper 71 stoffschlüssig verbunden.Furthermore, a machined contour 73 is provided in the hub outer body 71, in which the cast housing 12 is inserted with sufficient clearance for unimpeded rotation of the cell rotor 7. The shaft 13 is not inserted according to the invention in a disc 18 in the form of a cast rim star and screwed by a screw 19 with the disc 18. The disc 18 is integrally connected to the hub outer body 71.

In vorteilhafter Weise können somit die Materialien der Scheibe 18 und des Nabenaußenkörpers 71 voneinander abweichen. Zwar ist der Einzelaufbau der erfindungsgemäß gebauten Welle-Nabe-Verbindung komplexer als ein einteiliges Gießen einer Nabe. Der Einzelaufbau rechnet sich aber bei größeren Stückzahlen über die Menge und ist insgesamt leichter.

Although the individual structure of the inventive shaft-hub connection is more complex than a one-piece molding of a hub. The single structure pays off but for larger quantities on the amount and is lighter overall. <B><u> reference numerals: </ u></b> 1 - hub 2 - Hub outer body 3 - inner tube 4a - sheet metal part 4b - sheet metal part 5a - sheet metal part 5b - sheet metal part 6 - Pressure wave machine 7 - cell rotor 7a - Row of cells 7b - Row of cells 7c - Sheet metal between 7a and 7b 8th - casing 9 - housing connection 10 - intake system 11 - Turbo pipe 12 - cast housing 13 - wave 14 - ball-bearing 15a - Lid and seal 15b - Lid and seal 16 - heat shield 17 - screw 18 - disc 19 - screw 20 - Range of 2 21 - Range of 2 71 - Hub outer body 72 - edited contour 73 - edited contour A - A - Cross-sectional plane B - Hot gas side C - Cold-gas side
