Definitions
- the invention describes a housing cover for an internal combustion engine, in particular cylinder head covers or oil pans, for releasable, liquid-tight attachment to the engine block, with an elastomeric seal on the edge of the housing cover wherein on the edge of the housing cover on the inside a directed towards the engine block axial extension is provided, the axially over protrudes the sealing surface, so that the housing cover is positioned at least correct position.

- they must have several features as detachable, liquid-tight engine parts and meet specific characteristics.
- a detachable connection housing cover must, among other things, be easy to assemble and position and consist of as few individual parts.
- the gasket in a housing cover must, inter alia, have a high dimensional fidelity or low relaxation, a high reusability and a good resistance to liquids in the engine and environmental influences.
- a housing cover as a valve cover for a cylinder head of an internal combustion engine proposed in which by the use of a metallic spring body, the biasing force can be adjusted to the seal.
- the seal is pressed on the cover edge, during tightening with a certain force on the engine block.
- the metallic spring body By using the metallic spring body, the valve cover is able to follow the relaxation of the seal.
- a disadvantage of this type of construction of a housing cover is that although the force on the seal can be kept relatively constant, a sliding movement of the lid edges on the sealing surface but nothing prevents it. Sliding movements of the lid edge can z. B. caused by fatigue of the housing cover material or excessive tightening torques of the cover screws.
- JP 63 083464 A or JP 06221441 A as well as the US-A-4164927 disclose generic housing cover for internal combustion engines. In the radial direction, the individual housing cover are well stirred in the axial direction but safe and good positioning during assembly is not guaranteed.
- the object of the invention is thus to develop a housing cover which counteracts the sliding movements of the lid edge and at the same time includes an assembly aid.
- the inventive axial extension of the housing cover sliding movements of the lid edge are no longer possible. Rather, it can be done a targeted positioning of the lid on the sealing surface of the engine block.
- This targeted positioning offers the advantage that the sealing surface on the engine block can be adapted exactly to the shape of the elastomeric sealing material. This in turn leads to material savings on the sealing surface, which in turn has a positive effect on the weight of the engine.
- Another advantage is that the extension of the housing cover a targeted and defined introduction of force in the elastomeric sealing material is possible, it follows that the voltages occurring can be reliably calculated and adjusted.
- the extension supports the assembly, so it serves during assembly as a joining aid and during the attachment for positioning of the housing cover.

- the extension on the edge of the lid is arranged circumferentially on the edge of the lid in a patented embodiment. Depending on the application and structural conditions, the extension on the edge of the lid may also be only partially formed.
- the partial training offers the advantage of less weight and the circumferential training the advantage of safer leadership.
- the extension projects beyond the sealing surface in the direction of the engine block and according to the invention forms an undercut relative to the engine block. According to the invention, partial as well as circumferential undercuts are conceivable.
- the housing cover is detachable and must be designed in such a way that an expansion of the housing cover without damaging the extension must be possible.
- curves at the ends of the extension serve to facilitate the joining of the housing cover.
- the slope extends from the inside of the housing cover in the direction of the outside.
- the undercut in the form of a bevel offers the advantage that when the cover edge is displaced, the housing cover is pulled in the direction of the sealing surface, at the same time increasing the sealing force. Using this advantage, the effect between sliding movement and construction of the sealing forces can be specifically influenced. Furthermore, the undercut in the form of a slope offers the possibility to bring a bias to the seal of the housing cover, so that a very accurate positioning takes place already in the joining phase, which in turn can have a positive effect on automated fastening methods.
- the handling of the housing cover in the automation of assembly processes is thus greatly facilitated.
- an additional sealing function can be generated in the production of the extension of the lid edge.

Description
Die Erfindung beschreibt einen Gehäusedeckel für eine Verbrennungskraftmaschine, insbesondere Zylinderkopfhauben oder Ölwannen, zum lösbaren, flüssigkeitsdichten Befestigen am Motorblock, mit einer elastomeren Dichtung am Rand des Gehäusedeckels wobei am Rand des Gehäusedeckel innenseitig eine in Richtung des Motorblocks gerichtete axiale Verlängerung vorgesehen ist, die axial über die Dichtfläche hinausragt, so dass der Gehäusedeckel mindestens lagegerecht positioniert ist.The invention describes a housing cover for an internal combustion engine, in particular cylinder head covers or oil pans, for releasable, liquid-tight attachment to the engine block, with an elastomeric seal on the edge of the housing cover wherein on the edge of the housing cover on the inside a directed towards the engine block axial extension is provided, the axially over protrudes the sealing surface, so that the housing cover is positioned at least correct position.
Im Rahmen komplexer Zusammenbaustrategien in der Automobilindustrie ist es heute allgemein üblich Motorenteile mit Merkmalen zu versehen, die die Montage erleichtern oder die es ermöglichen, dass Fügeeinrichtungen ganz entfallen können. Neben dieser Montagefreundlichkeit werden auch Eigenschaften, welche die Funktion der Bauteile beeinflussen in die Motorenteile integriert.As part of complex assembly strategies in the automotive industry, it is now common to provide engine parts with features that facilitate assembly or that allow joining devices can be completely eliminated. In addition to this ease of installation, features that influence the function of the components are also integrated into the engine components.
Im Besonderen sind hier Gehäusedeckel, wie Zylinderkopfhauben oder Ölwannen, angesprochen, die als fertiges Montageteil dem Motor zugeführt werden, sie müssen als lösbare, flüssigkeitsdichtende Motorenteile gleich mehrere Merkmale besitzen sowie spezifische Eigenschaften erfüllen.
Als lösbare Verbindung müssen Gehäusedeckel unter anderem leicht zu montieren und zu positionieren sein sowie aus möglichst wenig Einzelteilen bestehen.
Als spezifische Eigenschaften muß die Dichtung in einem Gehäusedeckel unter anderem eine hohe Formtreue bzw. geringe Relaxation, eine hohe Wiederverwendbarkeit sowie eine gute Beständigkeit gegen Flüssigkeiten im Motor und gegen Umgebungseinflüsse aufweisen.In particular, here housing cover, such as cylinder head covers or oil pans, addressed that are supplied as a finished mounting part of the engine, they must have several features as detachable, liquid-tight engine parts and meet specific characteristics.
As a detachable connection housing cover must, among other things, be easy to assemble and position and consist of as few individual parts.
As specific properties, the gasket in a housing cover must, inter alia, have a high dimensional fidelity or low relaxation, a high reusability and a good resistance to liquids in the engine and environmental influences.
Um der Relaxation der Dichtung entgegenzuwirken wird in der
Nachteilig bei dieser Art des Aufbaus eines Gehäusedeckels ist, dass zwar die Kraft auf die Dichtung relativ konstant gehalten werden kann, einer Schiebebewegung der Deckelränder über die Dichtfläche aber nichts entgegensteht. Schiebebewegungen des Deckelrandes können z. B. durch Ermüdung des Gehäusedeckelwerkstoffs oder durch überhöhte Anzugsmomente der Deckelschrauben entstehen. Dies gilt insbesondere wenn die Gehäusedeckelwerkstoffe keine ausreichende Festigkeit besitzen, die Bauteile nicht ausreichend steif konstruiert werden können oder eine ungünstige Verschraubungsanordnung vorliegt.
Die Dichtung kann infolge der Schiebebewegung schaden nehmen oder die Dichtkräfte auf den elastomeren Dichtungswerkstoff sind nicht mehr ausreichend um eine Leckage zu vermeiden.To counteract the relaxation of the seal is in the
A disadvantage of this type of construction of a housing cover is that although the force on the seal can be kept relatively constant, a sliding movement of the lid edges on the sealing surface but nothing prevents it. Sliding movements of the lid edge can z. B. caused by fatigue of the housing cover material or excessive tightening torques of the cover screws. This is especially true if the housing cover materials do not have sufficient strength, the components can not be designed sufficiently rigid or there is an unfavorable Verschraubungsanordnung.
The seal may be damaged as a result of the sliding movement or the sealing forces on the elastomeric sealing material are no longer sufficient to prevent leakage.
Die
Aufgabe der Erfindung ist es somit einen Gehäusedeckel zu entwickeln der den Schiebebewegungen des Deckelrandes entgegenwirkt und der gleichzeitig eine Montagehilfe beinhaltet.The object of the invention is thus to develop a housing cover which counteracts the sliding movements of the lid edge and at the same time includes an assembly aid.
Diese Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst, vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen dokumentiert.This object is achieved by the characterizing part of claim 1, advantageous developments of the invention are documented in the dependent claims.
Mittels der erfindungsgemäßen, axialen Verlängerung des Gehäusedeckels sind Schiebebewegungen des Deckelrandes nun nicht mehr möglich. Es kann vielmehr eine gezielte Positionierung des Deckels auf der Dichtfläche des Motorblocks erfolgen. Diese gezielte Positionierung bietet den Vorteil, das die Dichtfläche am Motorblock der Form des elastomeren Dichtungswerkstoffs exakt angepasst werden kann. Dies führt wiederum zu Materialersparnis an der Dichtfläche, was sich wiederum positiv auf das Gewicht des Motors auswirkt.
Ein weiterer Vorteil ist, dass durch die Verlängerung des Gehäusedeckels eine gezielte und definierte Krafteinleitung in den elastomeren Dichtungswerkstoff möglich wird, hieraus ergibt sich, dass die auftretenden Spannungen zuverlässiger berechnet und eingestellt werden können.
Neben diesen Vorteilen unterstützt die Verlängerung die Montage, so dient sie während des Zusammenbaus als Fügehilfe und während der Befestigung zur Positionierung des Gehäusedeckels. Wird die Verlängerung erfindungsgemäß so ausgebildet, dass sie den Gehäusedeckel während des Fügens bereits festklemmt so können damit Überkopfmontagen, wie sie beispielsweise an Ölwannen auftreten können, wesentlich erleichtert werden.
Die Verlängerung am Deckelrand ist in einer patentgemäßen Ausführungsform umlaufend am Deckelrand angeordnet. Je nach Anwendungfall und konstruktiven Gegebenheiten kann die Verlängerung am Deckelrand aber auch nur partiell ausgebildet sein. Dabei bietet die partielle Ausbildung den Vorteil des geringeren Gewichts und die umlaufende Ausbildung den Vorteil der sichereren Führung.
Die Verlängerung ragt in Richtung des Motorblocks über die Dichtfläche hinaus und bildet erfindungsgemäß eine Hinterschneidung bezogen auf den Motorblock. Erfindungsgemäß sind partielle wie auch umlaufende Hinterschneidungen vorstellbar. Hierbei ist jede Form der Hinterschneidung vorstellbar, wobei zu beachten bleibt, dass der Gehäusedeckel lösbar ist und in der Art ausgeführt sein muß, dass ein Ausbau des Gehäusedeckels ohne Beschädigung der Verlängerung möglich sein muß. So dienen beispielsweise Rundungen an den Enden der Verlängerung einem leichteren Fügen des Gehäusedeckels.By means of the inventive axial extension of the housing cover sliding movements of the lid edge are no longer possible. Rather, it can be done a targeted positioning of the lid on the sealing surface of the engine block. This targeted positioning offers the advantage that the sealing surface on the engine block can be adapted exactly to the shape of the elastomeric sealing material. This in turn leads to material savings on the sealing surface, which in turn has a positive effect on the weight of the engine.
Another advantage is that the extension of the housing cover a targeted and defined introduction of force in the elastomeric sealing material is possible, it follows that the voltages occurring can be reliably calculated and adjusted.
In addition to these advantages, the extension supports the assembly, so it serves during assembly as a joining aid and during the attachment for positioning of the housing cover. If the extension according to the invention is designed so that it already clamps the housing cover during joining so overhead mounting, as can occur, for example, on oil pans, can be substantially facilitated.
The extension on the edge of the lid is arranged circumferentially on the edge of the lid in a patented embodiment. Depending on the application and structural conditions, the extension on the edge of the lid may also be only partially formed. The partial training offers the advantage of less weight and the circumferential training the advantage of safer leadership.
The extension projects beyond the sealing surface in the direction of the engine block and according to the invention forms an undercut relative to the engine block. According to the invention, partial as well as circumferential undercuts are conceivable. Here, any shape of the undercut is conceivable, it should be noted that the housing cover is detachable and must be designed in such a way that an expansion of the housing cover without damaging the extension must be possible. For example, curves at the ends of the extension serve to facilitate the joining of the housing cover.
Die Schräge verläuft ausgehend von der Innenseite des Gehäusedeckels in Richtung der Außenseite. Die Hinterschneidung in Form einer Schräge bietet den Vorteil, dass bei einer Verschiebung des Deckelrandes der Gehäusedeckel in Richtung der Dichtfläche gezogen wird, wobei sich gleichzeitig die Dichtkraft erhöht. Unter Einsatz dieses Vorteils kann die Wirkung zwischen Schiebebewegung und Aufbau der Dichtkräfte gezielt beeinflusst werden. Ferner bietet die Hinterschneidung in Form einer Schräge die Möglichkeit eine Vorspannung auf die Dichtung des Gehäusedeckels zu bringen, so dass eine sehr genaue Positionierung schon in der Fügephase stattfindet, was sich wiederum positiv auf automatisierte Befestigungsverfahren auswirken kann.The slope extends from the inside of the housing cover in the direction of the outside. The undercut in the form of a bevel offers the advantage that when the cover edge is displaced, the housing cover is pulled in the direction of the sealing surface, at the same time increasing the sealing force. Using this advantage, the effect between sliding movement and construction of the sealing forces can be specifically influenced. Furthermore, the undercut in the form of a slope offers the possibility to bring a bias to the seal of the housing cover, so that a very accurate positioning takes place already in the joining phase, which in turn can have a positive effect on automated fastening methods.
Die Handhabung des Gehäusedeckels bei der Automatisierung von Zusammenbauprozessen wird somit wesentlich erleichtert.
Je nach eingestellter Maßtoleranz kann bei der Fertigung der Verlängerung des Deckelrandes eine zusätzliche Dichtfunktion erzeugt werden. Ein entscheidender Vorteil, wenn beispielsweise die Befestigungsschrauben unzureichend angezogen wurden und die Gefahr der Leckage entsteht.
Durch eine konstruktive Anpassung zwischen der Dichtfläche am Motorblock und der Verlängerung des Gehäusedeckels kann erfindungsgemäß ebenfalls eine leichteres Fügen des Gehäusedeckels ermöglicht werden. So ist es vorstellbar am Motorblock eine Fase anzuordnen, die es ermöglicht, dass die Verlängerung in den Gehäuseblock einrastet.
Der Gehäusedeckel kann aus beliebigen Werkstoffen bestehen, wird erfindungsgemäß vorzugsweise aber aus einem Kunststoff gefertigt. Die bei Kunststoffen auftretende Relaxation und die damit verbundenen Schiebebewegungen der Dichtungen auf der Dichtfläche werden nun durch die Verlängerung erfindungsgemäß vermieden.The handling of the housing cover in the automation of assembly processes is thus greatly facilitated.
Depending on the set dimensional tolerance, an additional sealing function can be generated in the production of the extension of the lid edge. A decisive advantage, for example, if the fastening screws were insufficiently tightened and the risk of leakage arises.
By a structural adaptation between the sealing surface on the engine block and the extension of the housing cover, a lighter joining of the housing cover can also be made possible according to the invention. So it is conceivable on the engine block to arrange a chamfer, which allows the extension into the housing block engages.
The housing cover may consist of any materials, but according to the invention preferably but made of a plastic. The relaxation occurring in plastics and the associated sliding movements of the seals on the sealing surface are now avoided by the extension according to the invention.
