Die vorliegende Erfindung betrifft eine Flanschvorrichtung für eine Luftzuführungseinrichtung einer Brennkraftmaschine, insbesondere eines Kraftfahrzeugs. Die Erfindung betrifft außerdem eine mit wenigstens einer solchen Flanschvorrichtung ausgestattete Sauganlage. The present invention relates to a flange device for an air supply device of an internal combustion engine, in particular of a motor vehicle. The invention also relates to a suction system equipped with at least one such flange device.
Aus der WO 2001/048368 A1 ist eine Flanschvorrichtung für eine Sauganlage einer Brennkraftmaschine bekannt, die ein Gehäuse aus Kunststoff aufweist und eine Kraftstoffverteilerleiste aus Metall besitzt. Das Gehäuse weist für jeden Zylinder der Brennkraftmaschine einen Einlasskanal auf, und die Kraftstoffverteilerleiste weist für jeden Zylinder einen Anschluss zum Anschließen eines Kraftstoffinjektors auf. Des Weiteren ist die bekannte Flanschvorrichtung mit einem Niederhalter aus Metall ausgestattet, mit dessen Hilfe das Gehäuse an der Brennkraftmaschine befestigt werden kann, wobei dieser Niederhalter die Kraftstoffverteilerleiste übergreift, sodass mit der Befestigung des Gehäuses gleichzeitig auch die Kraftstoffverteilerleiste festgelegt wird. From WO 2001/048368 A1 a flange device for an intake system of an internal combustion engine is known, which has a housing made of plastic and has a fuel rail of metal. The housing has an intake passage for each cylinder of the internal combustion engine, and the fuel rail has a port for connecting a fuel injector for each cylinder. Furthermore, the known flange device is equipped with a hold-down made of metal, with the aid of which the housing can be attached to the internal combustion engine, said holddown the fuel rail overlaps, so that at the same time the fuel rail is fixed with the attachment of the housing.
Aus der EP 1 270 917 A2 ist eine weitere Flanschvorrichtung bekannt, die wieder ein Gehäuse aus Kunststoff und eine Kraftstoffverteilerleiste aus Metall aufweist. Bei der bekannten Flanschvorrichtung sind an der Kraftstoffverteilerleiste Brückenabschnitte integral ausgeformt, welche das Gehäuse neben den Einlasskanälen übergreifen und mit denen die Kraftstoffverteilerleiste und somit auch das Gehäuse an der Brennkraftmaschine befestigt werden. From EP 1 270 917 A2 a further flange device is known, which again has a housing made of plastic and a fuel rail of metal. In the known Flanschvorrichtung bridge sections are integrally formed on the fuel rail, which overlap the housing adjacent to the inlet channels and with which the fuel rail and thus the housing are attached to the engine.
Aus der DE 197 42 908 A1 ist eine Sauganlage bekannt, deren Gehäuse aus Kunststoff hergestellt ist und an der eine Kraftstoffverteilerleiste aus Metall befestigt ist. Aus der DE 102 51 406 A1 ist eine weitere Flanschvorrichtung bekannt, bei der ein Kunststoffgehäuse an der Brennkraftmaschine befestigt wird, wobei das Gehäuse mit Rastausnehmungen bundförmige Rohrenden von Abzweigrohren eines Kühlmittelverteilerrohrs formschlüssig übergreift, um dadurch gleichzeitig das Kühlmittelverteilerrohr an der Brennkraftmaschine zu befestigen. Dabei verläuft das Kühlmittelverteilerrohr zwischen den Abzweigrohren an einer von der Brennkraftmaschine abgewandten Seite des Gehäuses, wodurch es die mit den Rohrenden zusammenwirkenden Abschnitte des Gehäuses übergreift. From DE 197 42 908 A1 a suction system is known, whose housing is made of plastic and to which a fuel rail made of metal is attached. From DE 102 51 406 A1 discloses a further flange device is known in which a plastic housing is attached to the internal combustion engine, wherein the housing with recesses collar-shaped pipe ends of branch pipes of a coolant manifold positively engages over, thereby at the same time to attach the coolant manifold to the internal combustion engine.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für eine Flanschvorrichtung bzw. für eine Sauganlage der eingangs genannten Art eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die sich insbesondere durch eine preiswerte Herstellbarkeit und/oder durch eine vereinfachte Montier- barkeit auszeichnet. The present invention is concerned with the problem of providing an improved or at least another embodiment for a flange device or for an intake system of the type mentioned, which is characterized in particular by a low-cost manufacturability and / or by a simplified mounting availability.
Erfindungsgemäß wird dieses Problem durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche. According to the invention, this problem is solved by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, am Gehäuse einer Flanschvorrichtung mehrere Brückenabschnitte anzuordnen, insbesondere integral auszuformen, die im montierten Zustand die Kraftstoffverteilerleiste an einer von der Brennkraftmaschine abgewandten Seite übergreifen. Im montierten Zustand ist die Kraftstoffverteilerliste an das Gehäuse angebaut, wobei Verteilerliste und Gehäuse separat hergestellte Bauteile sind. Die Abstützung der Brückenabschnitte an der Brennkraftmaschine erfolgt dabei durch Stützhülsen hindurch, die sich einerseits am Brückenabschnitt und andererseits an der Brennkraftmaschine abstützen. Das Gehäuse kann dadurch an der einen Seite der Kraftstoffverteiler- leiste direkt mit einem Flansch an der Brennkraftmaschine befestigt werden, während es auf der anderen Seite der Kraftstoffverteilerleiste durch die Stützhülsen hindurch im Bereich der Brückenabschnitte an der Brennkraftmaschine befestigt werden kann. Durch das Befestigen des Gehäuses an der Brennkraftmaschine wird dadurch auch gleichzeitig die lose in das Gehäuse eingelegte, eingeklemmte oder eingeklippte Kraftstoffverteilerleiste an der Brennkraftmaschine festgelegt, wodurch zusätzliche Befestigungsmaßnahmen entfallen können. Besonders vorteilhaft ist dabei die Integration der Brückenabschnitte in das Gehäuse. Das Gehäuse, das bevorzugt als Kunststoff-Spritzgussteil ausgestaltet ist, kann einschließlich der Brückenabschnitte mit vergleichsweise engen Herstellungstoleranzen gefertigt werden, wodurch die Befestigung an der Brennkraftmaschine einfach realisierbar ist. Des Weiteren vereinfacht sich die Handhabung, da die Brückenabschnitte mit dem Ansetzen des Gehäuses an der Brennkraftmaschine bereits ordnungsgemäß positioniert sind. Darüber hinaus ergibt sich eine signifikante Gewichtseinsparung, da auch die Brückenabschnitte aus Kunststoff hergestellt sind und somit vergleichsweise leicht sind. Bei alternativen Ausgestaltungen sind die Brückenabschnitte lösbar oder unlösbar mit dem Gehäuse verbunden und bilden so eine Baugruppe, die wie ein einstückig ausgebildetes Bauteil verwendet werden kann. The invention is based on the general idea of arranging, in particular integrally molding, a plurality of bridge sections on the housing of a flange device, which in the mounted state overlap the fuel distributor strip on a side remote from the internal combustion engine. In the mounted state, the fuel distribution list is attached to the housing, distribution list and housing are separately manufactured components. The support of the bridge sections on the internal combustion engine takes place through support sleeves which are supported on the one hand on the bridge section and on the other hand on the internal combustion engine. The housing can thereby on one side of the fuel rail bar can be attached directly to the internal combustion engine with a flange, while it can be fixed on the other side of the fuel rail through the support sleeves in the region of the bridge sections on the internal combustion engine. By attaching the housing to the internal combustion engine thereby also loosely inserted into the housing, trapped or clipped fuel rail is determined at the internal combustion engine, whereby additional fastening measures can be omitted. Particularly advantageous is the integration of the bridge sections in the housing. The housing, which is preferably designed as a plastic injection-molded part, including the bridge sections can be manufactured with comparatively tight manufacturing tolerances, whereby the attachment to the internal combustion engine is easily feasible. Furthermore, the handling is simplified, since the bridge sections are already properly positioned with the attachment of the housing to the internal combustion engine. In addition, there is a significant weight saving, since the bridge sections are made of plastic and thus are relatively easy. In alternative embodiments, the bridge sections are releasably or non-detachably connected to the housing and thus form an assembly that can be used as an integrally formed component.
Entsprechend einer vorteilhaften Ausführungsform können die Stützhülsen aus Metall hergestellt sein und in den jeweiligen Brückenabschnitt eingesetzt sein. Durch die metallischen Stützhülsen lassen sich besonders hohe Zugkräfte bzw. Druckkräfte zwischen Gehäuse und Brennkraftmaschine abstützen, um das Gehäuse mit hinreichender Kraft gegen die Brennkraftmaschine vorzuspannen. Durch die Verwendung der metallischen Stützhülsen wird ein Kriechen des Kunststoffes unter Zug- bzw. Druckbelastung verhindert. Zur Verbesserung der Kraftübertragung zwischen den Brückenabschnitten und der Kraftstoffverteilerleiste können die Brückenabschnitte in einem der Kraftstoffverteilerleiste zugewandten, Kontaktbereich komplementär zur Kraftstoffverteilerleiste geformt sein und daran flächig zur Anlage kommen. According to an advantageous embodiment, the support sleeves may be made of metal and inserted into the respective bridge section. By the metallic support sleeves can be supported particularly high tensile forces or compressive forces between the housing and the engine to bias the housing with sufficient force against the internal combustion engine. By using the metallic support sleeves creep of the plastic under tensile or compressive load is prevented. To improve the transmission of force between the bridge sections and the fuel rail, the bridge sections may be formed in a fuel rail facing the contact area complementary to the fuel rail and come to rest flat against it.
Entsprechend einer besonders vorteilhaften Ausführungsform können am Gehäuse Einlassrohre integral ausgeformt sein, die jeweils mit mindestens einem der Einlasskanäle kommunizierend verbunden sind. Hierdurch kann der Integrationsgrad der Flanschvorrichtung erhöht werden, was die Handhabung der According to a particularly advantageous embodiment, inlet pipes can be integrally formed on the housing, which are each communicatively connected to at least one of the inlet channels. As a result, the degree of integration of the flange can be increased, which the handling of the
Flanschvorrichtung bzw. deren Montage vereinfacht. Flange device or their assembly simplified.
Entsprechend einer Weiterbildung können am Gehäuse Abstützstege integral ausgeformt sein, die sich einerseits an den Brückenabschnitten und andererseits an den Einlassrohren abstützen. Über diese Abstützstege findet somit eine AbStützung der Brückenabschnitte an den Einlassrohren statt, wodurch die Stabilität der Flanschvorrichtung gesteigert werden kann. According to a development may be integrally formed on the housing Abstützstege, which are supported on the one hand on the bridge sections and on the other hand on the inlet pipes. Over this Abstützstege thus takes place a support of the bridge sections on the inlet pipes, whereby the stability of the flange device can be increased.
Gemäß einer anderen vorteilhaften Weiterbildung kann am Gehäuse außerdem ein Frischluftverteiler integral ausgeformt sein, der an einer von den Einlasskanälen abgewandten Seite mit den Einlassrohren kommunizierend verbunden ist. Auch diese Maßnahme führt zu einer Steigerung des Integrationsgrads der Flanschvorrichtung, was die Handhabung und Montierbarkeit erleichtert. According to another advantageous refinement, a fresh air distributor can also be integrally formed on the housing, which is communicatively connected to the inlet tubes at a side remote from the inlet channels. This measure also leads to an increase in the degree of integration of the flange device, which facilitates handling and assembly.
Gemäß dieser Weiterbildung ist eine Sauganlage gebildet, die sämtliche Funktionseinheiten, wie z.B. Flansch, Brückenabschnitte, Frischluftverteiler, Einlassrohre und Einlasskanäle, in einem Bauteil aufweist. In die Sauganlage wird die Kraftstoffverteilerleiste eingeklemmt oder eingeklippt oder lose eingelegt und gemeinsam mit der Sauganlage durch diese an der Brennkraftmaschine montiert. Gemäß einer anderen Ausführung kann die Flanschvorrichtung, die zumindest über den Flansch, Brückenabschnitte und die Einlasskanäle verfügt, als gesonderte Einheit ausgeführt sein und mit einem Saugrohr, das zumindest über einen Frischluftverteiler und Einlassrohre verfügt, zu einer kompletten Sauganlage zusammengefügt, insbesondere verschraubt, werden. According to this development, a suction system is formed, which has all functional units, such as flange, bridge sections, fresh air manifold, inlet pipes and inlet ducts in a component. In the intake system, the fuel rail is clamped or clipped or loosely inserted and mounted together with the intake by this on the engine. According to another embodiment, the flange device, which has at least the flange, bridge sections and the inlet channels, be designed as a separate unit and assembled with a suction pipe, which has at least one fresh air manifold and inlet pipes to a complete intake system, in particular screwed.
Bei einer alternativen Ausführung kann die Flanschvorrichtung auch mit einer anderen Luftzuführungseinheit als einem Saugrohr verbunden werden. Derartige Luftzuführungseinheiten können z.B. Kompressoren oder Luftverteiler mit/ohne Kühler, sein. In an alternative embodiment, the flange device may also be connected to a different air supply unit than a suction tube. Such air supply units may e.g. Compressors or air distributors with / without radiator.

Entsprechend Fig. 1 umfasst eine nur teilweise dargestellte Lufzuführungseinrich- tung 1 , bei der es sich bevorzugt um eine Sauganlage handeln kann, zur Frischluftversorgung einer Brennkraftmaschine, die insbesondere in einem Kraftfahrzeug angeordnet sein kann, zumindest eine Flanschvorrichtung 2 sowie eine Frischluftleitung 3, die an eine Einlassseite der Flanschvorrichtung 2 angeschlossen ist. Die Flanschvorrichtung 2 ist an die nicht dargestellte Brennkraftmaschine anschließbar. Bei der Brennkraftmaschine handelt es sich um einen Kolbenmotor, der mehrere Zylinder aufweist. Die Flanschvorrichtung 2 dient zur Versorgung aller Zylinder der Brennkraftmaschine mit Frischluft, sofern es sich bei der Brennkraftmaschine um einen Reihenmotor handelt. Alternativ dient die Flanschvorrichtung 2 zur Versorgung aller Zylinder einer Zylinderbank der Brennkraftmaschine mit Frischluft, sofern es sich bei der Brennkraftmaschine um einen V-Motor handelt. Entsprechendes gilt dann auch für andere Motortypen, wie Boxermotor und W-Motor. According to FIG. 1, an air supply device 1, which is only partially shown and may preferably be an intake system, comprises a fresh air supply to an internal combustion engine, which can be arranged in a motor vehicle, at least one flange device 2 and a fresh air line 3, which an inlet side of the flange 2 is connected. The flange device 2 can be connected to the internal combustion engine, not shown. The internal combustion engine is a piston engine having a plurality of cylinders. The flange device 2 is used to supply all cylinders of the internal combustion engine with fresh air, if it is an internal combustion engine in the internal combustion engine. Alternatively, the flange device 2 serves to supply all cylinders of a cylinder bank of the internal combustion engine with fresh air, as long as the internal combustion engine is a V-engine. The same applies to other engine types, such as the boxer engine and the W engine.
Entsprechenden den Figuren 1 -5 umfasst die Flanschvorrichtung 2 ein Gehäuse 4 sowie eine Kraftstoffverteilerleiste 5. Das Gehäuse 4 ist aus Kunststoff hergestellt, insbesondere mittels Spritzgusstechnik. Das Gehäuse 4 weist zumindest einen Einlasskanal 6 je Zylinder der Brennkraftmaschine auf. Im Beispiel sind - ohne Beschränkung der Allgemeinheit - genau vier Einlasskanäle 6 vorgesehen, die zu vier Zylindern der Brennkraftmaschine führen. Insoweit handelt es sich bei der zugehörigen Brennkraftmaschine um einen Vier-Zylinder-Reihenmotor oder um einen V-8-Zylinder-Motor oder kurz V8-Motor. Corresponding to Figures 1 -5, the flange 2 includes a housing 4 and a fuel rail 5. The housing 4 is made of plastic, in particular by means of injection molding. The housing 4 has at least one inlet channel 6 per cylinder of the internal combustion engine. In the example - without limiting the generality - exactly four inlet channels 6 are provided which lead to four cylinders of the internal combustion engine. In that regard, it is the associated internal combustion engine to a four-cylinder in-line engine or a V-8-cylinder engine or short V8 engine.
Die Kraftstoffverteilerleiste 5 ist aus Metall hergestellt und weist für jeden Zylinder einen Anschluss 7 zum Anschließen eines - hier nicht gezeigten - Kraftstoff! njek- tors auf. Diese Kraftstoffinjektoren dienen zum Einspritzen von Kraftstoff in den jeweiligen Zylinder. Sie sind über die Anschlüsse 7 gemeinsam an die gleiche Kraftstoffverteilerleiste 5 angeschlossen, sodass es sich hierbei um ein sog. Common-Rail-System handelt. Die Kraftstoffverteilerleiste 5 ist hier als Rohr ausgestaltet, das sich durch einen kreisförmigen Querschnitt auszeichnet. Ebenso sind auch andere Querschnittsgeometrien für die Kraftstoffverteilerleiste 5 denkbar, wie z. B. ein Rechteckquerschnitt. The fuel rail 5 is made of metal and has for each cylinder a connection 7 for connecting a - not shown here - fuel! njek- tor. These fuel injectors serve to inject fuel into the respective cylinder. They are connected via the connections 7 together to the same fuel rail 5, so this is a so-called. Common rail system. The fuel rail 5 is designed here as a tube, which is characterized by a circular cross-section. Likewise, other cross-sectional geometries for the fuel rail 5 are conceivable, such. B. a rectangular cross-section.
Das Gehäuse 4 weist an einer Seite, die im montierten Zustand der Brennkraftmaschine zugewandt ist, einen Flansch 8 auf. Dieser Flansch 8 umschließt die Einlasskanäle 6 bzw. deren Auslassöffnungen. Mit dem Flansch 8 kann das Gehäuse 4 an der Brennkraftmaschine befestigt werden. Außerdem sind am Gehäuse 4 mehrere Brückenabschnitte 9 integral ausgeformt. Zweckmäßig ist je Zylinder bzw. je Einlasskanal 6 ein solcher Brückenabschnitt 9 vorgesehen. The housing 4 has a flange 8 on a side facing the internal combustion engine in the mounted state. This flange 8 surrounds the inlet channels 6 and their outlet openings. With the flange 8, the housing 4 can be attached to the internal combustion engine. In addition, a plurality of bridge portions 9 are formed integrally on the housing 4. Expediently, such a bridge section 9 is provided per cylinder or per inlet channel 6.
Dementsprechend sind die Brückenabschnitte 9 jeweils auf Höhe eines der Einlasskanäle 6 angeordnet. Die Brückenabschnitte 9 übergreifen die lose in das Gehäuse 4 eingelegte bzw. eingeklemmte Kraftstoffverteilerleiste 5 an einer vom Flansch 8 abgewandten Seite. Des Weiteren sind die Brückenabschnitte 9 bezüglich der Längsrichtung des Gehäuses 4 jeweils mit einer Stützhülse 10 ausgestattet. Die jeweilige Stützhülse 10 ist dabei distal zu den Einlasskanälen 6 am jeweiligen Brückenabschnitt 9 angeordnet, derart, dass sich die Kraftstoffverteilerleiste 5 zwischen den Stützhülsen 10 und den Einlasskanälen 6 befindet. Accordingly, the bridge sections 9 are each arranged at the level of one of the inlet channels 6. The bridge sections 9 engage over the fuel rail 5, which is loosely inserted or clamped in the housing 4, on a side facing away from the flange 8. Furthermore, the bridge sections 9 are each equipped with a support sleeve 10 with respect to the longitudinal direction of the housing 4. The respective support sleeve 10 is arranged distally to the inlet channels 6 at the respective bridge section 9, such that the fuel rail 5 is located between the support sleeves 10 and the inlet channels 6.
Durch diese Stützhülsen 10 hindurch kann der jeweilige Brückenabschnitt 9 an der Brennkraftmaschine befestigt werden. Grundsätzlich können die Stützhülsen 10 aus Kunststoff hergestellt sein. In diesem Fall können sie auch integral an den Brückenabschnitten 9 und somit integral am Gehäuse 4 ausgeformt sein. Bevorzugt ist jedoch eine separate Herstellung der Stützhülsen 10, wodurch es möglich ist, die Stützhülsen 10 aus Metall herzustellen und an das Gehäuse 4 anzubauen. Hierzu werden die Stützhülsen 10 in den jeweiligen Brückenabschnitt 9 eingesetzt. Entsprechend Fig. 5 kann der jeweilige Brückenabschnitt 9 für die jeweilige Stützhülse 10 eine entsprechende Einstecköffnung 1 1 aufweisen, in welche die Hülse 10 einsteckbar ist. Die Ver- schraubung des Gehäuses 4 mit der Brennkraftmaschine erfolgt dann im Bereich der Brückenabschnitte 9 zweckmäßig so, dass ein Schraubenschaft die Stützhülse 10 koaxial durchsetzt, während ein Schraubenkopf, insbesondere über eine Scheibe, an der von der Brennkraftmaschine abgewandten axialen Stirnseite der Stützhülse 10 anliegt und dabei radial übersteht und dadurch auch axial an einem ringförmigen Sitz 12 abgestützt ist, der die Stecköffnung 1 1 an einer von der Brennkraftmaschine abgewandten Seite einfasst. Auf diese Weise werden die gesamten Schraubkräfte von der Stützhülse 10 aufgenommen, sodass das Gehäuse 4 durch die Verschraubung nicht belastet wird. Through these support sleeves 10 through the respective bridge portion 9 can be attached to the engine. In principle, the support sleeves 10 may be made of plastic. In this case, they may also be formed integrally on the bridge sections 9 and thus integrally on the housing 4. Preferably, however, is a separate production of the support sleeves 10, whereby it is possible to make the support sleeves 10 made of metal and grow on the housing 4. For this purpose, the support sleeves 10 are inserted into the respective bridge section 9. According to Fig. 5, the respective bridge portion 9 for the respective support sleeve 10 have a corresponding insertion opening 1 1, in which the sleeve 10 can be inserted. The screwed connection of the housing 4 with the internal combustion engine then expediently takes place in the region of the bridge sections 9 in such a way that a screw shaft passes coaxially through the support sleeve 10, while a screw head rests, in particular via a disc, against the axial end face of the support sleeve 10 facing away from the internal combustion engine and thereby protrudes radially and thereby also axially supported on an annular seat 12, which surrounds the plug-in opening 1 1 on a side facing away from the engine side. In this way, the entire screwing forces are absorbed by the support sleeve 10, so that the housing 4 is not loaded by the screw.
Die Stützhülsen 10 können dabei in den Stecköffnungen 1 1 durch Kraftschluss oder Reibschluss gehalten sein. Ebenso ist es möglich, die Stützhülsen 10 in das Gehäuse 4 einzuschweißen. The support sleeves 10 may be held in the insertion openings 1 1 by adhesion or frictional engagement. It is also possible to weld the support sleeves 10 in the housing 4.
Zur Verschraubung des Gehäuses 4 an der Brennkraftmaschine an einer von den Stützhülsen 10 abgewandten Seite der Kraftstoffverteilerleiste 5 kann das Gehäuse 4 entsprechend Fig. 4 mehrere Durchgangsöffnungen 13 aufweisen, in die zweckmäßig ebenfalls Hülsen 14 eingesetzt sein können, um die Verschrau- bungskräfte aufzunehmen. Diese Hülsen 14 können insbesondere eingeschweißt sein. Ebenso kann ein Schraubkopf oder eine Scheibe die von der Brennkraftma- schine abgewandte axiale Stirnseite der jeweiligen Hülse 14 radial übergreifen, um so das Gehäuse 4 an der Brennkraftmaschine festzulegen. For screwing the housing 4 to the internal combustion engine on a side facing away from the support sleeves 10 side of the fuel rail 5, the housing 4 according to FIG. 4, a plurality of through-openings 13, in which expediently sleeves 14 may be used to accommodate the Verschra- bungskräfte. These sleeves 14 may in particular be welded. Likewise, a screw head or a disk can be used by the Brennkraftma- machine axially overlap the axial end face of the respective sleeve 14 so as to fix the housing 4 to the internal combustion engine.
Gemäß Fig. 5 können die Brückenabschnitte 9 in einem der Kraftstoffverteilerleis- te 5 zugewandten Kontaktbereich 15 komplementär zur Kraftstoffverteilerleiste 5 geformt sein, derart, dass die Kraftstoffverteilerleiste 5 in diesem Kontaktbereich 15 flächig am jeweiligen Brückenabschnitt 9 zur Anlage kommt. Hierdurch kann eine besonders hohe Kraftübertragung gewährleistet werden. Im Beispiel ist die Kraftstoffverteilerleiste 5 mit einem kreisförmigen Außenquerschnitt versehen. Passend dazu ist der Kontaktbereich 15 halbkreisförmig konfiguriert. According to FIG. 5, the bridge sections 9 in a contact region 15 facing the fuel distributor strip 5 can be shaped to be complementary to the fuel distributor strip 5, such that the fuel distributor strip 5 abuts the respective bridge section 9 flatly in this contact region 15. As a result, a particularly high power transmission can be ensured. In the example, the fuel rail 5 is provided with a circular outer cross-section. Fits to the contact area 15 is configured semicircular.
Bei der hier gezeigten Ausführungsform sind am Gehäuse 4 außerdem mehrere Einlassrohre 16 integral ausgeformt. Diese Einlassrohre 16 stehen gemäß Fig. 5 jeweils mit wenigstens einem Einlasskanal 6 kommunizierend in Verbindung. Im Beispiel sind genau vier Einlassrohre 16 vorgesehen, die jeweils mit einem der vier Einlasskanäle 6 kommunizierend verbunden sind. Bei einer Ausführungsform, bei der das Gehäuse 4 je Zylinder zwei Einlasskanäle aufweist, kann auch vorgesehen sein, ein Einlassrohr 16 mit zwei Einlasskanälen kommunizierend zu verbinden, die zum gleichen Zylinder führen. In the embodiment shown here, a plurality of inlet tubes 16 are also formed integrally on the housing 4. According to FIG. 5, these inlet tubes 16 communicate with at least one inlet channel 6 in a communicating manner. In the example, exactly four inlet pipes 16 are provided, each of which communicates with one of the four inlet ducts 6. In an embodiment in which the housing 4 per cylinder has two inlet channels, it may also be provided to connect an inlet tube 16 communicating with two inlet channels that lead to the same cylinder.
Im Beispiel ist am Gehäuse 4 außerdem ein Frischluftverteiler 17 integral ausgeformt, der mit den Einlasskanälen 16 kommunizierend verbunden ist. Dabei ist der Frischluftverteiler 17 an einer von den Einlasskanälen 6 abgewandten Seite an den Einlassrohren 16 angeordnet. In the example, a fresh air manifold 17 is integrally formed on the housing 4, which is communicatively connected to the inlet channels 16. In this case, the fresh air distributor 17 is arranged on the inlet pipes 16 on a side facing away from the inlet channels 6.
Bei der hier gezeigten Ausführungsform sind außerdem Abstützstege 18 vorgesehen, die ebenfalls integral am Gehäuse 4 ausgeformt sein können. Diese Abstützstege 18 stützen die Brückenabschnitte 9 an den Einlassrohren 16 ab, und zwar an einer von der Kraftstoffverteilerleiste 5 abgewandten Seite. Hierzu erstrecken sich die Abstützstege 18 einerseits entlang der Brückenabschnitte 9 zumindest soweit, dass sie die Kraftstoffverteilerleiste 5 überlappen. Andererseits erstrecken sich die Abstützstege 18 entlang des jeweiligen Einlassrohrs 16 bis zu einem Endbereich 19 des jeweiligen Einlassrohrs 16, der zum zugehörigen Einlasskanal 6 distal angeordnet ist. Ferner sind die Abstützstege 18 je Brückenabschnitt 9 doppelt ausgeführt, wobei die beiden Abstützstege 18 des jeweiligen Brückenabschnitts 9 gemäß Fig. 4 beiderseits der jeweiligen Stützhülse 10 angeordnet sind. In the embodiment shown here also Abstützstege 18 are provided, which may also be integrally formed on the housing 4. These support webs 18 support the bridge sections 9 on the inlet pipes 16, specifically on a side facing away from the fuel rail 5. For this extend the support webs 18 on the one hand along the bridge sections 9 at least to the extent that they overlap the fuel rail 5. On the other hand, the support webs 18 extend along the respective inlet pipe 16 to an end region 19 of the respective inlet pipe 16, which is arranged distally to the associated inlet channel 6. Furthermore, the support webs 18 are executed twice per bridge section 9, the two support webs 18 of the respective bridge section 9 according to FIG. 4 being arranged on both sides of the respective support sleeve 10.
Bei der hier gezeigten Ausführungsform erstreckt sich der Frischluftverteiler 17 parallel zur einer Längsrichtung 20 der Flanschvorrichtung 2. Diese Längsrichtung 20 wird dabei durch die Richtung definiert, in welcher die Einlasskanäle 6 nebeneinander angeordnet sind. Gleichzeitig bildet diese Längsrichtung 20 auch die Längsrichtung des Flansches 8 und des Gehäuses 4. Somit erstreckt sich der Frischluftverteiler 17 bei der hier gezeigten Ausführungsform parallel zum In the embodiment shown here, the fresh air manifold 17 extends parallel to a longitudinal direction 20 of the flange device 2. This longitudinal direction 20 is defined by the direction in which the inlet channels 6 are arranged side by side. At the same time, this longitudinal direction 20 also forms the longitudinal direction of the flange 8 and the housing 4. Thus, the fresh air manifold 17 in the embodiment shown here extends parallel to
Flansch 8. Bzgl. der Längsachse 20 kann der Frischluftverteiler 17 bei der hier gezeigten Ausführungsform stirnseitig einen Anschlussflansch 21 aufweisen, ü- ber den die Frischluftleitung 3 der Sauganlage 1 an die Flanschvorrichtung 1 bzw. an den Frischluftverteiler 17 anschließbar ist. Flange 8. Bzgl. the longitudinal axis 20, the fresh air manifold 17 in the embodiment shown here frontally have a connection flange 21, via which the fresh air line 3 of the intake system 1 to the flange 1 and the fresh air manifold 17 can be connected.
Entsprechend Fig. 5 kann im Gehäuse 4 eine Klappenanordnung 22 vorgesehen sein, die mehrere Klappen 23 aufweist, mit deren Hilfe einzelne Einlasskanäle 6 oder alle Einlasskanäle 6 hinsichtlich des durchströmbaren Querschnitts steuerbar sind. Sofern je Zylinder genau ein Einlasskanal 6 vorgesehen ist, kann die Klappenanordnung 22 zweckmäßig je Einlasskanal 6 eine solche Klappe 23 aufweisen. Sofern je Zylinder zwei Einlasskanäle 6 vorgesehen sind, kann die Klappenanordnung 22 für jeden zweiten Einlasskanal 6 eine derartige Klappe 23 aufweisen. Wie insbesondere Fig. 4 entnehmbar ist, kann das Gehäuse 4 an einer vom Flansch 8 abgewandten und in Fig. 4 dem Betrachter zugewandten Seite mehrere Versteifungsstege 24 aufweisen, die zu einer intensiven Aussteifung des Gehäuses 4 im Bereich der Brückenabschnitte 9 führen. Erkennbar sind dabei die Versteifungsstege 24 hier so gestaltet, dass sich jeweils mittig zwischen zwei Brückenabschnitten 9 eine kreiszylindrische Knotenstelle 25 bildet, von der mehrere Versteifungsstege 24 sternförmig ausgehen. Einzelne Stege 24a erstrecken sich dabei parallel zur Längsachse 20 des Gehäuses 4 und verbinden dadurch die einzelnen Knotenstellen 25 geradlinig miteinander. Andere Versteifungsstege 24b verlaufen entlang des außen liegenden Randes der Brückenabschnitte 9. Wieder andere Versteifungsstege 24c verbinden die Bereiche der Brückenabschnitte 9, in denen die Stützhülsen 10 angeordnet sind, mit den Bereichen des Gehäuses 4, in denen die Hülsen 14 angeordnet sind. According to FIG. 5, a flap arrangement 22 can be provided in the housing 4, which has a plurality of flaps 23 with the aid of which individual inlet channels 6 or all inlet channels 6 can be controlled with regard to the cross-section which can be flowed through. If exactly one inlet channel 6 is provided per cylinder, the flap arrangement 22 may expediently have such a flap 23 per inlet channel 6. If two inlet channels 6 are provided for each cylinder, the flap arrangement 22 can have such a flap 23 for every second inlet channel 6. 4, the housing 4 can have a plurality of reinforcing webs 24 on a side facing away from the flange 8 and facing the observer in FIG. 4, which lead to an intensive stiffening of the housing 4 in the region of the bridge sections 9. Visible here are the stiffening webs 24 here designed so that in each case centrally between two bridge sections 9 forms a circular cylindrical node 25, go out of the more stiffening webs 24 in a star shape. Individual webs 24a extend parallel to the longitudinal axis 20 of the housing 4 and thereby connect the individual nodes 25 in a straight line with each other. Other stiffening webs 24b extend along the outer edge of the bridge sections 9. Again other stiffening webs 24c connect the areas of the bridge sections 9 in which the support sleeves 10 are arranged, with the areas of the housing 4, in which the sleeves 14 are arranged.
Zur Betätigung der Klappenanordnung 22 kann außen am Gehäuse 4 stirnseitig ein Stellantrieb 26 vorgesehen sein, der bspw. als Druckdose konfiguriert sein kann. Der Stellantrieb 26 kann mit einem Hebelelement 27 antriebsgekoppelt sein, das seinerseits mit einer hier nicht gezeigten Betätigungswelle gekoppelt ist, derart, dass eine Betätigung des Stellantriebs 26 das Hebelelement 27 verschwenkt und dadurch die Betätigungswelle mit den daran angebrachten Klappen 23 verdreht. For actuating the flap arrangement 22, an actuator 26 can be provided on the outside of the housing 4 on the front side, which can be configured, for example, as a pressure cell. The actuator 26 can be drive-coupled with a lever element 27, which in turn is coupled to an actuating shaft, not shown here, such that actuation of the actuator 26 pivots the lever element 27 and thereby rotates the actuating shaft with the flaps 23 attached thereto.
