Abstract
Description
Die vorliegende Erfindung betrifft einen Luftfilter eines Kraftfahrzeuges mit einem Luftfiltergehäuse, das an einen zur Verfügung stehenden Bauraum in einem Kraftfahrzeug angepasste Außenkonturen aufweist.The The present invention relates to an air filter of a motor vehicle with an air filter housing attached to one having stationary space in a motor vehicle adapted outer contours.
Ein
solcher Luftfilter ist aus der
Der freie Bauraum in Motorräumen wird insbesondere durch Aerodynamik-Anforderungen, Design-Anforderungen und steigende Anforderungen an den Fußgängerschutz beschränkt.Of the free space in engine compartments is particularly due to aerodynamic requirements, Design requirements and increasing demands on pedestrian protection limited.
Bei Neukonstruktionen von Kraftfahrzeugen sind zum Beispiel Grenzwerte für ein sogenanntes Head Injury Criterion einzuhalten, das ein Maß für die Aufprallverzögerung eines Kopfes bei einer Kollision des Kraftfahrzeugs mit einem Fußgänger ist. Die Einhaltung dieser Grenzwerte erfordert zum Beispiel einen ausreichenden Abstand zwischen Motorhaube und dem darunter liegenden unnachgiebig harten Verbrennungsmotor.at New designs of motor vehicles are for example limit values to comply with a so-called Head Injury Criterion, that is a measure of the impact delay a head in a collision of the motor vehicle with a pedestrian is. Compliance with these limits, for example, requires one sufficient distance between the bonnet and the underlying relentless hard combustion engine.
Bisher übliche Luftfiltergehäuse stellen ebenfalls harte Strukturen dar, die bei einer üblichen Anordnung im Motorraum die Einhaltung der HIC-Grenzwerte erschweren. Die Einhaltung eines ausreichenden Abstands zur Motorhaube, oder allgemeiner, zu für den Fußgängerschutz relevanten möglichen Aufprallflächen, führt damit zu einer Beschränkung des im Motorraum zur Verfügung stehenden Einbauraums.So far usual Air filter housings are also hard structures, the compliance with a conventional arrangement in the engine compartment HIC limits. Adherence to a sufficient Distance to the hood, or more generally, to for pedestrian protection relevant possible impact surfaces leads thus to a restriction of the engine compartment available standing installation space.
Aus
der
Vor diesem Hintergrund besteht ein Bedarf nach einem Luftfilter, der auch bei Kraftfahrzeugen mit dicht gepackten Motorräumen verwendbar ist und der die Formgebung des Kraftfahrzeugs im Hinblick auf das Design und die Aerodynamik auch bei steigenden Anforderungen an den Fußgängerschutz im Fall von Unfällen möglichst wenig beschränkt.In front There is a need for an air filter which also in motor vehicles with tightly packed engine compartments is usable and the shape of the motor vehicle with regard to the design and the aerodynamics even with increasing requirements to the pedestrian protection in case of accidents limited as little as possible.
Ein Verzicht auf das Gehäuse des Luftfilters und eine Unterbringung des gehäuselosen Luftfilters außerhalb des Motorraums in einem Bauraum im Bug des Kraftfahrzeuges würde dieses Bedürfnis erfüllen und außerdem Gewicht und Kosten sparen. Ein solcher Bauraum kann sich zum Beispiel bei einem Kraftfahrzeug mit einer vor dem Verbrennungsmotor quer im Kraftfahrzeug liegenden Karosseriestruktur zwischen dieser Karosseriestruktur und einem sich davor und/oder darüber spannenden Karosserieabschlussteil ergeben.One Waiver of the housing of the air filter and a housing the caseless air filter outside the engine compartment in a space in the bow of the motor vehicle would this Meeting need and weight as well and save costs. Such a space can, for example, at a motor vehicle with a front of the engine transversely in Motor vehicle body structure between this body structure and in front of and / or over exciting body completion part result.
Den Vorteilen eines gehäuselosen, dort angeordneten Luftfilters stehen jedoch auch gravierende Nachteile gegenüber. So kann es Probleme mit unerwünschter Warmluftansaugung aus dem Motorraum geben. Zum Vermeiden einer unerwünschten Ansaugung warmer Luft aus dem Motorraum müssten die Spalten zwischen dem Motorraum und dem Bauraum aufwändig abgedichtet werden. Ein solcher Bauraum müsste darüber hinaus Öffnungen für einströmende Rohluft aufweisen. Bei hohen Fahrgeschwindigkeiten tritt jedoch mehr Luft durch diese Öffnungen ein, als vom Verbrennungsmotor abgesaugt wird. Die nicht benötigte Luft tritt dann unkontrolliert aus Spalten zwischen einzelnen Außenflächen der Fahrzeugkarosserie aus und stört die außen anliegende Luftströmung. Dadurch steigt der Luftwiderstand unerwünscht an.The Advantages of a caseless, arranged there air filter However, there are also serious disadvantages. So There may be problems with unwanted warm air intake enter the engine compartment. To avoid unwanted suction Warm air from the engine compartment would have the gaps between the engine compartment and the space to be sealed consuming. Such a space would have openings beyond for incoming raw air. At high Driving speeds, however, more air passes through these openings on, as sucked by the internal combustion engine. The unneeded Air then enters uncontrollably from gaps between individual outer surfaces the vehicle body and disturbs the outside adjoining air flow. This increases the air resistance undesirable.
Vor diesem Hintergrund besteht die Aufgabe der Erfindung in der Angabe eines Luftfilters, der auch bei Kraftfahrzeugen mit dicht gepackten Motorräumen verwendbar ist, der die Formgebung des Kraftfahrzeugs im Hinblick auf das Design und die Aerodynamik möglichst wenig beschränkt und der die genannten Nachteile eines gehäuselosen Luftfilters vermeidet.In front In this background, the object of the invention in the specification an air filter, which is also used in motor vehicles with tightly packed Engine compartment is usable, the shape of the motor vehicle as far as possible in terms of design and aerodynamics little limited and the disadvantages of a caseless air filter avoids.
Diese Aufgabe wird durch die Summe der Merkmale des Anspruchs 1 gelöst.These Task is solved by the sum of the features of claim 1.
Durch die Verwendung eines Luftfilters mit einem Luftfiltergehäuse werden die genannten Probleme der Warmluftansaugung und der Erhöhung des Luftwiderstandes vermieden. Die Anpassung von Außenkonturen des Luftfiltergehäuses an einen Einbauraum, der durch einen Montageträger von dem Motorraum getrennt ist und der in Fahrtrichtung nach vorne durch ein Karosserieabschlussteil begrenzt wird, erlaubt eine Unterbringung des Luftfilters außerhalb eines dicht gepackten Motorraums.By the use of an air filter with an air filter housing the mentioned problems of warm air intake and increase of the Air resistance avoided. The adaptation of outer contours the air filter housing to an installation space by a Mounting bracket is separated from the engine compartment and the in Direction of travel is limited to the front by a body end part is allowed to accommodate the air filter outside a tightly packed engine room.
Aus dieser aus dem Motorraum heraus verlagerten Anordnung des Luftfilters könnten sich Zielkonflikte mit Anforderungen an den Fußgängerschutz ergeben. Diese Zielkonflikte werden dadurch vermieden, dass das aus Schaumstoff bestehende oder mit Schaumstoff ummantelte Luftfiltergehäuse eine nachgiebige Struktur darstellt. Die Nachgiebigkeit ermöglicht zum Beispiel eine Einhaltung der HIC-Kriterien auch bei einer Anordnung des Luftfilters dicht unter und/oder hinter der Karosserieoberfläche in einem für den Fußgängerschutz relevanten Bereich.From this arrangement of the air filter displaced out of the engine compartment, there could be conflicting objectives with requirements for pedestrian protection. These conflicting goals are avoided by being made of foam or with Foam encased air filter housing represents a resilient structure. The compliance allows, for example, compliance with the HIC criteria even with an arrangement of the air filter just below and / or behind the body surface in a relevant area for pedestrian protection.
Weitere Vorteile ergeben sich aus den abhängigen Ansprüchen, der Beschreibung und den beigefügten Figuren.Further Advantages result from the dependent claims, the description and the attached figures.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
