Description

Die Erfindung betrifft eine Ansauganlage für eine mehrzylindrige Brennkraftmaschine, wobei die Ansauganlage schwingungsentkoppelt oberhalb der Zylinder an der Brennkraftmaschine gehalten ist.The invention relates to an intake system for a multi-cylinder internal combustion engine, the intake system being held in a vibration-decoupled manner above the cylinders on the internal combustion engine.

In der DE-36 41 811 C1 ist eine Ansauganlage für eine mehrzylindrige Brennkraftmaschine offenbart, die unter Zwischenschaltung von elastischen Lagerelementen schwingungsentkoppelt am Zylinderkopf gehalten ist. Die Lagerelemente sind dabei zwischen Ansauganlage und Stützen am Zylinderkopf mittels Verschraubungen auf Druck beansprucht. Bei der Montage der Ansauganlage ist der Zugang zu diesen Verschraubungen sowie zu den Verbindungsstellen zwischen Einzelsaugrohren der Ansauganlage und in einer Flanschfläche mündenden, im Zylinderkopf ausgebildeten Einlaßkanälen erschwert.DE-36 41 811 C1 discloses an intake system for a multi-cylinder internal combustion engine, which is held on the cylinder head in a vibration-decoupled manner with the interposition of elastic bearing elements. The bearing elements are stressed between the intake system and supports on the cylinder head by means of screw connections. When installing the intake system, access to these screw connections as well as to the connection points between the individual intake pipes of the intake system and inlet channels opening in a flange surface and formed in the cylinder head is made more difficult.

Der Erfindung liegt die Aufgabe zugrunde, eine Ansauganlage so zu gestalten, daß eine einfache und schnelle Montage an der Brennkraftmaschine gewährleistet ist und dabei gleichzeitig eine optimale Schwingungsentkopplung der Ansauganlage von der Brennkraftmaschine erzielt wird.The invention has for its object to design an intake system so that a simple and quick installation on the internal combustion engine is ensured and at the same time optimal vibration decoupling of the intake system from the internal combustion engine is achieved.

Die Lösung dieser Aufgabe gelingt mit den Merkmalen des Anspruches 1 oder mit den Merkmalen des Anspruches 8. Weitere, die Erfindung vorteilhaft ausgestaltende Merkmale sind in den Unteransprüchen genannt.This object is achieved with the features of claim 1 or with the features of claim 8. Further features which advantageously configure the invention are mentioned in the subclaims.

Nach einer ersten Ausführung der Erfindung ist es durch die Anordnung eines zwischen der Ansauganlage und dem Zylinderkopf wirkenden, auf Zug beanspruchten Entkoppelelementes und eines weiteren, zwischen dem Zylinderkopf und Einzelsaugrohren der Ansauganlage auf Druck beansprucht angeordneten Entkoppelelementes möglich, die Ansauganlage in wenigen Schritten zu montieren bzw. zu demontieren. Hierzu ist es lediglich erforderlich, von oben zugängliche, die Ansauganlage vertikal durchdringende Spannmitteln zu spannen, wodurch die Ansauganlage bereits über das sich am Zylinderkopf abstützende Entkoppelelement elastisch und schwingungsentkoppelt mit der Brennkraftmaschine verbunden ist. Die von den Spannmitteln dabei auf die Ansauganlage übertragenen Kräfte stützen sich an den weiteren Entkoppelelementen ab, die vor der Montage der Ansauganlage zwischen diese und die Zylinderköpfe gelegt werden.According to a first embodiment of the invention, the arrangement of a decoupling element acting between the intake system and the cylinder head, which is subjected to tensile stress, and a further decoupling element which is arranged between the cylinder head and individual intake pipes of the intake system and which is subjected to pressure, makes it possible to assemble the intake system in a few steps to disassemble. All that is required for this is access from above, vertically penetrating the intake system Clamping means, whereby the intake system is already connected to the internal combustion engine elastically and vibration-decoupled via the decoupling element supported on the cylinder head. The forces transmitted from the clamping means to the intake system are based on the further decoupling elements which are placed between the intake system and the cylinder heads before the assembly of the intake system.

Für die Montage bzw. Demontage ist somit lediglich das Einlegen der weiteren Entkoppelelemente vor dem Aufsetzen der Ansauganlage erforderlich, anschließend das Spannen der z.B. als Zugschraube ausgebildeten Spannmittel.For assembly or disassembly, all that is required is to insert the further decoupling elements before attaching the intake system, then tightening the e.g. clamping device designed as a tension screw.

Sollte die Zugänglichkeit des weiteren Entkoppelelementes bei einer Reihen-Brennkraftmaschine z.B. aufgrund der Einbauverhältnisse erschwert oder aber bei einer V-Brennkraftmaschine, deren einstückiger Ansaugverteiler der Ansauganlage die in Zylinderköpfen ausgebildeten Einlaßkanäle vollständig abdeckt, unmöglich sein, so ermöglicht diese Anordnung dennoch eine einfache und schnelle Montage.If the accessibility of the further decoupling element in a series internal combustion engine e.g. difficult because of the installation conditions or impossible with a V-type internal combustion engine, the one-piece intake manifold of the intake system which completely covers the intake ports formed in cylinder heads, this arrangement nevertheless enables simple and quick installation.

In vorteilhafter Ausgestaltung dieser Ausführung der Erfindung ist zwischen den gleichzeitig als Dichtung wirkenden weiteren Entkoppelelementen und einer Flanschfläche ein Saugrohrstutzen angeordnet, wobei sich zwischen benachbarten Saugrohrstutzen die Entkoppelelemente über Befestigungspfeifen an der Flanschfläche abstützt. Dadurch ist keine weitere, bearbeitete Flanschfläche am Zylinderkopf für die Abstützung dieser Befestigungspfeifen erforderlich.In an advantageous embodiment of this embodiment of the invention, an intake manifold socket is arranged between the further decoupling elements, which simultaneously act as a seal, and a flange surface, the decoupling elements being supported on the flange surface via fastening pipes between adjacent suction tube sockets. This means that no further machined flange surface on the cylinder head is required to support these mounting pipes.

In weiterer Ausgestaltung sind die einzelnen, zu jedem Zylinder führenden Saugrohrstutzen einer Zylinderreihe gemeinsam mit den Befestigungspfeifen einstückig als Brücke ausgebildet. Bei z.B. einer V-Brennkraftmaschine mit vier Zylindern pro Zylinderreihe sind diese Brücken mittels einer zwischen dem ersten und dem zweiten sowie einer zwischen dem dritten und dem vierten Saugrohrstutzen angeordneten Befestigungspfeife mit der Flanschfläche verschraubt. Die Entkoppelelemente sind an einstückig mit den Befestigungspfeifen ausgebildeten Armen gehalten, die sich quer zu der Brücke bis in unmittelbarer Nähe der Zylinderköpfe erstrecken. Die Zugschrauben können dadurch in einfacher Weise einen außenliegenden Bereich des Ansaugverteilers, z.B. einen Luftsammler durchdringen. Um unterhalb der Ansauganlage im V der Brennkraftmaschine angeordnete Bauteile zu erreichen, brauchen somit lediglich vier Spannschrauben gelöst zu werden, wodurch der Ansaugverteiler abnehmbar wird.In a further embodiment, the individual intake manifold connecting pieces of a row of cylinders leading to each cylinder are formed in one piece together with the fastening pipes as a bridge. In, for example, a V-type internal combustion engine with four cylinders per row of cylinders, these bridges are screwed to the flange surface by means of a fastening pipe arranged between the first and the second and between the third and the fourth intake manifold socket. The decoupling elements are held on arms which are formed in one piece with the fastening pipes and which extend transversely to the bridge in the immediate vicinity of the cylinder heads. The tension screws can thus easily penetrate an external area of the intake manifold, for example an air collector. To below the To reach the intake system in the V of the internal combustion engine, all that is required is to loosen four clamping screws, which makes the intake manifold removable.

Gemäß einer zweiten Ausführung der Erfindung ist die Ansauganlage mit Dämpfern an der Brennkraftmaschine gehalten, welche ein lösbar mit der Brennkraftmaschine verbundenes, topfartiges Gehäuse umfassen. In diesem Gehäuse ist eine gummielastische Masse angeordnet, die von einer mit einer endseitig angeordneten Scheibe versehene Spannhülse durchdrungen wird, welche mit der Ansauganlage lösbar verbunden ist. Mit dieser Anordnung ist eine einfache und schnelle Montage bzw. Demontage der Ansauganlage an der Brennkraftmaschine bei gleichzeitiger Schwingungsentkopplung durch die lösbare Verbindung zwischen Spannhülse und Ansauganlage gegeben.According to a second embodiment of the invention, the intake system is held on the internal combustion engine with dampers which comprise a pot-like housing detachably connected to the internal combustion engine. In this housing a rubber-elastic mass is arranged, which is penetrated by a clamping sleeve provided with an end disc, which is detachably connected to the intake system. With this arrangement, a simple and quick assembly or disassembly of the intake system on the internal combustion engine with simultaneous vibration decoupling is provided by the detachable connection between the adapter sleeve and the intake system.

In vorteilhafter Ausgestaltung dieser Ausführung sind Ansauganlage und Spannhülsen mit Zugschrauben verbunden, welche in der Ansauganlage ausgebildete Aufnahmen nahezu vertikal durchdringen. Dadurch ist eine gute Zugänglichkeit der Verbindung gewährleistet. Ein in der Aufnahme angeordneter Anschlag begrenzt die durch das Verschrauben von der Spannhülse auf die gummielastische Masse übertragenden Kräfte, so daß eine gewünschte Kennung des Dämpfers einstellbar ist.In an advantageous embodiment of this embodiment, the intake system and clamping sleeves are connected with lag screws which penetrate receptacles formed in the intake system almost vertically. This ensures good access to the connection. A stop arranged in the receptacle limits the forces transmitted by the screwing of the adapter sleeve to the rubber-elastic mass, so that a desired identifier of the damper can be set.

Von einer V-Brennkraftmaschine 1 ist nur eine Zylinderreihe 2 mit vier Zylindern angedeutet dargestellt. Die Brennkraftmaschine 1 ist gemeinsam mit einer Ansauganlage 3 symmetrisch zu einer senkrecht verlaufenden Ebene E ausgebildet, die eine nicht gezeigte Kurbelwelle aufnimmt. Die Zylinderreihe 2 weist einen nur angedeutet gezeigten Zylinderkopf 4 mit einer Haube 5 und einer Flanschfläche 6 auf, in der im Zylinderkopf 4 ausgebildete Einlaßkanäle 7 münden.Of a V-type internal combustion engine 1, only one row of cylinders 2 with four cylinders is shown. The internal combustion engine 1 is formed together with an intake system 3 symmetrically to a perpendicular plane E, which receives a crankshaft, not shown. The cylinder bank 2 has a cylinder head 4 (only indicated) with a hood 5 and a flange surface 6, into which inlet channels 7 formed in the cylinder head 4 open.

Oberhalb und zwischen den Zylinderreihen 2 ist die Ansauganlage 3 angeordnet, die einen Ansaugverteiler 9, bestehend aus Luftsammlern 10 und Einzelsaugrohren 11 sowie zwischen den Einzelsaugrohren 11 und den Flanschflächen 6 angeordnete Saugrohrstutzen 12 aufweist. Die Saugrohrstutzen 12 einer Zylinderreihe 2 sind einstückig als Brücke 13 ausgebildet, die einen Teil der Ansauganlage 3 bildet. Zwischen den Saugrohrstutzen 12 weist die Brücke 13 zwei einstückig mit dieser ausgebildete Befestigungspfeifen 14 auf. Quer zu der Ebene E erstrecken sich an die Befestigungspfeifen 14 angegossene Arme 15 bis in die Nähe der Zylinderköpfe 4.Above and between the rows of cylinders 2, the intake system 3 is arranged, which has an intake manifold 9, consisting of air collectors 10 and individual intake pipes 11, and intake manifold nozzles 12 arranged between the individual intake pipes 11 and the flange surfaces 6. The intake manifolds 12 of a row of cylinders 2 are formed in one piece as a bridge 13, which forms part of the intake system 3. Between the intake manifold 12, the bridge 13 has two fastening pipes 14 formed integrally therewith. Arms 15 cast onto the fastening pipes 14 extend transversely to the plane E up to the vicinity of the cylinder heads 4.

An der geodätisch höchst liegenden Stelle tragen die Arme 15 lösbar mit ihnen verbundene, als Dämpfer 16 ausgebildete, topfartige Entkoppelelemente. Die Dämpfer 16 weisen als Baueinheit innerhalb eines geschlossenen Volumens V eine gummielastische Masse 17 auf, die von einer mit einem Innengewinde 18 versehenen Spannhülse 19 durchsetzt ist, deren unterer Abschluß von einer mit der Masse 17 in Kontakt stehenden Scheibe 20 gebildet wird.At the geodetically highest point, the arms 15 releasably connect to them, designed as dampers 16, pot-like decoupling elements. The dampers 16 have as a unit within a closed volume V a rubber-elastic mass 17, which is penetrated by an internally threaded 18 clamping sleeve 19, the lower end of which is formed by a disc 20 in contact with the mass 17.

Zwischen den aneinandergrenzenden Einzelsaugrohren 11 und den Saugrohrstutzen 12 sind als Dichtung 25 ausgebildete weitere Entkoppelelemente angeordnet, welche für eine Zylinderreihe 2 zu einem Dichtstreifen 26 zusammengefaßt untereinander verbunden und mit nicht gezeigten Nasen gegen Verrutschen gesichert sind.Between the adjoining individual intake pipes 11 and the intake manifold 12, further decoupling elements configured as seals 25 are arranged, which for a row of cylinders 2 are combined to form a sealing strip 26 and are secured against slipping with noses (not shown).

Bei der erstmaligen Montage der Ansauganlage 3 an der Brennkraftmaschine 1 werden zunächst die Brücken 13 mittels der Befestigungspfeifen 14 sowie weiterer, in einem Flansch 27 ausgebildeter Öffnungen 28 mit der Flanschfläche 6 verschraubt. Die Brücken 13 weisen Kraftstoffversorgungsleitungen 30 sowie Einspritzventilaufnahmen 31 auf, die nicht näher erläutert sind. Zur weiteren Montage bzw. zur Demontage z.B. zu Servicezwecken wird ein Dichtstreifen 26 auf jede Brücke 13 gelegt. Jeweils ein Dämpfer 16 wird mit einer durch das Innengewinde 18 zugänglichen Schraube 33 mit einem Arm 15 lösbar verbunden. Anschließend wird der Ansaugverteiler 9 mit den Einzelsaugrohren 11 auf die Dichtstreifen 26 gelegt. Durch vertikal in den Luftsammlern 10 ausgebildete Aufnahmen 34 werden als Zugschrauben 35 ausgebildete Spannmittel bis zur Spannhülse 19 geführt und mit deren Innengewinde 18 verschraubt. Eine in der Aufnahme 34 als Anschlag 44 ausgebildete Anlageschulter begrenzt die Stauchung der Masse 17 auf ein für eine wirksame Entkopplung optimales Maß.When mounting the intake system 3 on the internal combustion engine 1 for the first time, the bridges 13 are first screwed to the flange surface 6 by means of the fastening pipes 14 and further openings 28 formed in a flange 27. The bridges 13 point Fuel supply lines 30 and injection valve receptacles 31, which are not explained in detail. For further assembly or disassembly, for example for service purposes, a sealing strip 26 is placed on each bridge 13. A damper 16 is detachably connected to an arm 15 by a screw 33 accessible through the internal thread 18. Subsequently, the intake manifold 9 with the individual intake pipes 11 is placed on the sealing strips 26. By means of receptacles 34 formed vertically in the air collectors 10, tensioning means designed as tension screws 35 are guided up to the clamping sleeve 19 and screwed to their internal thread 18. An abutment shoulder formed as a stop 44 in the receptacle 34 limits the compression of the mass 17 to an optimum dimension for effective decoupling.

Der gesamte Ansaugverteiler 9 ist durch die vorbeschriebene Anordnung durch das Lösen von lediglich vier Zugschrauben 35 von der Brennkraftmaschine lösbar. Anstelle der Zugschrauben 35 können als Spannmittel z.B. auch mit einem Bajonettverschluß versehene Schnellspannelemente verwendet werden, die mit einer Drehung um 180° Grad Ansaugverteiler 9 und Dämpfer 16 miteinander verspannen.The entire intake manifold 9 can be detached from the internal combustion engine by the arrangement described above by loosening only four lag screws 35. Instead of the lag screws 35, e.g. quick-release elements provided with a bayonet lock are also used, which clamp the intake manifold 9 and damper 16 to one another with a rotation of 180 °.

Die Entkoppelelemente werden unabhängig von der Art der Spannmittel ausschließlich auf Zug beansprucht, wobei die vom Dämpfer 16 mittels der Schraube 33, dem Arm 15 und der Befestigungspfeifen 14 übertragenen Zugkräfte in der Flanschfläche 6 des Zylinderkopfes 4 abgestützt werden. Die von dem Spannmittel dabei auf den Ansaugverteiler 9 übertragenen Kräfte stützen sich über das dadurch auf Druck beanspruchte weitere Entkoppelelement und die Saugrohrstutzen 12 ebenfalls auf der Flanschfläche 6 ab.The decoupling elements are only subjected to tension irrespective of the type of clamping means, the tensile forces transmitted by the damper 16 by means of the screw 33, the arm 15 and the fastening pipes 14 being supported in the flange surface 6 of the cylinder head 4. The forces transmitted from the tensioning means to the intake manifold 9 are also supported on the flange surface 6 via the further decoupling element and the intake manifold stubs 12 which are thereby subjected to pressure.

Eine zweite Ausführung der Erfindung ist in Fig. 4 dargestellt. Identische Bezugszeichen kennzeichnen in beiden Ausführungen gleiche Bauteile. Die Ansauganlage 3 ist mit Dämpfern 16 schwingungsentkoppelt an der Brennkraftmaschine 1 gehalten. Die Dämpfer 16 weisen ein topfartiges Gehäuse 36 auf, welches mit Schrauben 33 an der Brennkraftmaschine 1 lösbar befestigt ist. In dem Volumen V des Dämpfers 16 ist die von der Spannhülse 19 durchdrungene, gummielastische Masse 17 angeordnet, die sich an einem in einer Sicke 37 des Gehäuses 36 gehaltenen Deckel 38 abstützt.A second embodiment of the invention is shown in FIG. 4. Identical reference symbols denote the same components in both versions. The intake system 3 is held on the internal combustion engine 1 in a vibration-decoupled manner with dampers 16. The dampers 16 have a pot-like housing 36 which is detachably fastened to the internal combustion engine 1 with screws 33. In the volume V of the damper 16, the rubber-elastic mass 17 penetrated by the clamping sleeve 19 is arranged, which is supported on a cover 38 held in a bead 37 of the housing 36.

In der dem Deckel 38 zugewandten Oberseite der Masse 17 sind Aussparungen 39 angeordnet, in die zwei Krallen bildende ausgestanzte Fahnen 40 des Deckels 38 eingreifen.
Von einem das Innengewinde 18 aufnehmenden Hülsenkörper 41 ausgehend verlaufen radial zwei abfallend gestaltete Rippen 42 auf der Scheibe 20, die in korrespondierende Ausnehmungen 43 der Masse 17 eingreifen.Recesses 39 are arranged in the upper side of the mass 17 facing the cover 38, into which cut-out lugs 40 of the cover 38 forming two claws engage.
Starting from a sleeve body 41 receiving the internal thread 18, radially two sloping ribs 42 run radially on the disk 20, which engage in corresponding recesses 43 in the mass 17.

Die Montage bzw. Demontage der Ansauganlage erfolgt bezüglich der Dämpfer 16 in analoger Weise wie bei der ersten Ausführung der Erfindung. Vor dem Verschrauben füllt die Masse 17 das Volumen V nahezu vollständig aus und preßt dabei die Scheibe 20 an den dem Deckel 38 gegenüberliegenden Boden des Gehäuses 36. Während des Verschraubens wird die Spannhülse 19 aus dem Dämpfer 16 herausgezogen und preßt dabei die Masse 17 auf ein eine bestimmte Kennung einstellendes Maß zusammen. Dieses Maß ist durch eine in der Aufnahme 34 als Anschlag 44 ausgebildete Anlageschulter begrenzt. Bei einem Lösen oder Anziehen der Zugschrauben 35 ist ein Verdrehen der Spannhülse 19 gegenüber der Masse 17 bzw. ein Verdrehen der Masse 17 gegenüber dem Gehäuse 36 durch die in die Ausnehmungen 43 eingreifenden Rippen 42 bzw. durch die in die Aussparungen 39 eingreifenden Fahnen 40 verhindert. Die Abstützung der von den Zugschrauben 35 in den Luftsammler 10 eingeleiteten Kräfte erfolgt beispielsweise über nicht gezeigte Saugrohre der Ansauganlage 3.The assembly or disassembly of the intake system takes place with respect to the damper 16 in an analogous manner as in the first embodiment of the invention. Before screwing, the mass 17 fills the volume V almost completely and thereby presses the disk 20 against the bottom of the housing 36 opposite the cover 38. During the screwing, the clamping sleeve 19 is pulled out of the damper 16 and presses the mass 17 onto it a measure setting a certain identifier. This dimension is limited by an abutment shoulder formed in the receptacle 34 as a stop 44. When the lag screws 35 are loosened or tightened, the clamping sleeve 19 is prevented from rotating with respect to the mass 17 or the mass 17 is rotated with respect to the housing 36 by the ribs 42 engaging in the recesses 43 or by the lugs 40 engaging in the recesses 39 . The forces introduced by the tension screws 35 into the air collector 10 are supported, for example, via suction pipes (not shown) of the intake system 3.
