Description
Die Erfindung betrifft eine aus Kunststoff hergestellte, Luftschall absorbierende Motorabdeckung mit Oberflächendekor für einen Verbrennungsmotor eines Kraftfahrzeuges, mit Befestigungsmitteln und/oder Ausnehmungen zur Befestigung der Motorabdeckung an einem Verbrennungsmotor.The The invention relates to a made of plastic, airborne sound absorbent engine cover with surface decoration for an internal combustion engine Motor vehicle, with fastening means and / or recesses for Attaching the engine cover to an internal combustion engine.
Kraftfahrzeuge, insbesondere Dieselfahrzeuge werden heute zunehmend mit schallabsorbierenden Motorabdeckungen ausgestattet, die als Formteile regelmäßig auch eine Designfunktion haben.Motor vehicles In particular, diesel vehicles are now becoming increasingly sound-absorbing Engine covers are equipped as moldings regularly as well have a design function.
Herkömmliche
Motorabdeckungen werden mit aufwendigen Absorbermaterialien versehen.
In der Regel bestehen diese aus Schaumstoffen oder Vliesmaterialien,
die in einem separaten Verfahren der Form der Motorabdeckung sowie
der Kontur des abzudeckenden Motors angepasst werden. So ist beispielsweise
aus der
In
Extrusions-Blasformtechnik hergestellte Schallabsorber, die zur
schallisolierenden Kapselung des Motorraums unterhalb des Motors
angeordnet werden, sind bekannt (vgl.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine schallabsorbierende Motorabdeckung mit Designfunktion bereitzustellen, die sich relativ kostengünstig herstellen und einfach recyceln lässt.Of the present invention is based on the object, a sound-absorbing To provide engine cover with design function that is relative economical produce and easy to recycle.
Erfindungsgemäß wird diese Aufgabe durch eine Motorabdeckung mit den Merkmalen des Anspruchs 1 gelöst.According to the invention this Task by an engine cover with the features of the claim 1 solved.
Die erfindungsgemäße Motorabdeckung ist im Wesentlichen dadurch gekennzeichnet, dass sie aus einem Blasformteil gebildet ist, dessen dem Verbrennungsmotor abgewandter Wandabschnitt mit dem Oberflächendekor versehen ist und dessen dem Verbrennungsmotor zugewandter Wandabschnitt eine Vielzahl kästchen- und/oder becherartige Hohlkammern aufweist, wobei zumindest eine Mehrzahl der Hohlkammern einem gemeinsamen, in dem Blasformteil eingeschlossenen Luftraum angehört, und wobei das Oberflächendekor aus mindestens einem mit dem Blasformteil hinterblasenen oder verbundenen Dekorteil gebildet ist.The Engine cover according to the invention is essentially characterized in that it consists of a blow molding is formed, facing away from the internal combustion engine wall portion with the surface decor is provided and the internal combustion engine facing wall portion a Variety box- and / or cup-like hollow chambers, wherein at least one Plurality of the hollow chambers a common, in the blow molding belongs to enclosed airspace, and where the surface decor from at least one behind-blown with the blow molding or connected Decor part is formed.
Das Blasformteil der erfindungsgemäßen Motorabdeckung lässt sich mit Kostenvorteil im so genannten „One-Shot- Verfahren" herstellen. Das Dekorteil lässt sich als vorgefertigter Einleger mit einer Oberflächengüte herstellen, die höchste Design-Anforderungen erfüllt. Das hinterblasene Dekorteil kann dabei aus dem gleichen Werkstoff (Kunststofftyp) wie das Blasformteil gefertigt sein, so dass sich die vollständige Motorabdeckung problemlos sortenrein recyceln lässt. Bei dem Dekorteil kann es sich insbesondere um ein separat gespritztes Kunststoffteil mit form- und/oder farbgestalteter Sichtseite handeln. Das Dekorteil kann insbesondere aus einem gegenüber dem Blasformteil andersfarbigen, durchgefärbten Kunststoffteil, insbesondere einer silberfarbenen Kunststofffolie bestehen.The Blow molding of the engine cover according to the invention let yourself with a cost advantage in the so-called "one-shot process." The decorative part can be manufactured as a prefabricated insert with a surface finish, the highest design requirements Fulfills. The hinterblasene decorative part can be made of the same material (Plastic type) be made as the blow molding, so that the complete Engine cover can easily be recycled sorted. In the decorative part can it is in particular a separately molded plastic part with molded and / or color-rendered visible side act. The decorative part can especially from one opposite the blow molding differently colored, through-colored plastic part, in particular consist of a silver-colored plastic film.
Sofern gewünscht, kann als Dekorteil auch ein geformtes Blech oder eine Metallfolie mit Designcharakter gewählt und mit einem extrudierten thermoplastischen Kunststoffschlauch oder zwei thermoplastischen Kunststofffolien in einem entsprechenden Formwerkzeug hinterblasen werden, so dass die Rückseite des Dekorteils stoffschlüssig mit dem eine Vielzahl von kästchen- und/oder becherartigen Hohlkammern aufweisenden Blasformteil verbunden ist.Provided desired can also be a molded sheet or a metal foil as a decorative part chosen with design character and with an extruded thermoplastic plastic tube or two thermoplastic films in a corresponding one Behind the molding tool, so that the back of the decorative part cohesively with which has a large number of and / or cup-shaped hollow chambers having blow molding connected is.
Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Motorabdeckung besteht darin, dass die Hohlkammern des Blasformteils zumindest teilweise mit einem rieselfähigen Schwermaterial, wie z.B. Quarzsand, Bariumsulfat und/oder Magnetit gefüllt sind. Hierdurch wird die Schalldämmwirkung der Motorabdeckung erhöht.A advantageous embodiment of the engine cover according to the invention consists in that the hollow chambers of the blow molding at least partially with a free-flowing Heavy material, e.g. Quartz sand, barium sulfate and / or magnetite filled are. As a result, the soundproofing effect the engine cover increased.
In der erfindungsgemäßen schallabsorbierenden Motorabdeckung können vorteilhaft auch Zusatzfunktionen integriert werden. So können in dem Blasformteil zum Beispiel ein Luftführungskanal, ein Flüssigkeitsbehälter und/oder eine Flüssigkeitsleitung integriert sein. Die durch die Motorabdeckung durchgeleitete Luft bzw. Flüssigkeit kann so energiesparend erwärmt werden. Bei dem Flüssigkeitsbehälter kann es sich insbesondere um einen Scheibenwischwasserbehälter handeln.In the sound-absorbing invention Engine cover can Advantageously, additional functions are integrated. So can in the blow molding, for example, an air duct, a liquid container and / or a liquid line be integrated. The air passing through the engine cover or liquid can be heated so energy-saving become. In the liquid container can it is in particular a windscreen wiper water tank.
Eine besonders hohe Temperaturbeständigkeit lässt sich für die erfindungsgemäße Motorabdeckung erreichen, wenn der dem Verbrennungsmotor zugewandte Wandabschnitt des Blasformteils zumindest bereichsweise mit einer mikroperforierten Aluminiumfolie abgedeckt ist. Durch die Verwendung einer mikroperforierten Aluminiumfolie lässt sich zudem eine relativ breitbandige Schallabsorption erzielen.A particularly high temperature resistance can be achieved for the engine cover according to the invention if the wall section of the blow molding part facing the internal combustion engine is covered at least in regions with a microperforated aluminum foil. By using a Microperforated aluminum foil can also achieve a relatively broadband sound absorption.
Eine weitere vorteilhafte Ausgestaltung der erfindungsgemäßen Motorabdeckung besteht darin, dass in dem dem Verbrennungsmotor zugewandten Wandabschnitt des Blasformteils Strukturen zur formschlüssigen Anbringung von Steckkupplungselementen ausgebildet sind. Hierdurch wird eine einfache und schnelle Montage der Motorabdeckung ermöglicht. Vorzugsweise sind die Steckkupplungselemente dabei schwingungsentkoppelnd ausgestaltet.A further advantageous embodiment of the engine cover according to the invention is that in the internal combustion engine facing wall section Blasformteils Structures for the positive attachment of plug-in coupling elements are formed. This is a simple and quick installation the engine cover allows. Preferably, the plug-in coupling elements are vibration decoupling designed.
Weitere bevorzugte und vorteilhafte Ausgestaltungen der erfindungsgemäßen Motorabdeckung sind in den Unteransprüchen angegeben.Further preferred and advantageous embodiments of the engine cover according to the invention are in the subclaims specified.
