Description

Die Erfindung betrifft einen mehrteiligen Luftführungskanal für die Anordnung im Motorraum eines durch eine Verbrennungskraftmaschine betriebenen Fahrzeuges, mit einem ersten, karosserieseitigen Kanalteil und mit einem zweiten, motorseitigen Kanalteil, wobei beide Kanalteile sowohl axial als auch radial relativ zueinander beweglich, dicht miteinander verbunden sind.The invention relates to a multi-part air duct for the arrangement in the engine compartment of a powered by an internal combustion engine vehicle, with a first, body-side channel part and a second, motor-side channel part, both channel parts are both axially and radially relative to each other movable, tightly interconnected.

Diese Beweglichkeit relativ zueinander soll einerseits den Einbau des Luftführungskanals im beschränkt zur Verfügung stehenden freien Teil des Motorraumes mit einem hierzu gekrümmten Verlauf ermöglichen und andererseits verhindern, dass sich die Verbrennungskraftmaschine über den Luftführungskanal am Fahrzeugchassis abstützt und somit auf dieses und damit den Fahrgastraum Vibrationen überträgt.This mobility relative to each other should on the one hand enable the installation of the air duct in limited available free part of the engine compartment with a curved course and on the other hand prevent the internal combustion engine is supported on the air duct on the vehicle chassis and thus transmits to this and thus the passenger compartment vibrations.

Bekannte Luftführungskanäle dieser Art sind für den genannten Zweck entweder gesamthaft oder über einen Teil ihrer Längsausdehnung aus einem elastisch verformbaren, beispielsweise faserverstärkten Material ausgeführt, wobei die Verformbarkeit durch besondere Formen der Kanalführung oder Form der Kanalwände, z. B. nach Art eines Faltenbalges, verbessert wurde. Bei letzterer Ausführung sind zwischen verschiedenen Materialbereichen Verbindungen z. B. durch Verkleben oder Verschweissen herzustellen, falls nicht mechanische Kupplungsmittel in Form von Schlauchbriden o. dgl. vorgesehen werden. Sowohl die Herstellung solcher bekannter Luftführungskanäle unter Anwendung verschiedener Herstellungsverfahren für solche unterschiedlichen Komponenten als auch ihre Montage im Motorraum eines Fahrzeuges ist jedoch verhältnismässig aufwändig und entsprechend teuer.Known air ducts of this type are designed for the purpose either total or over part of their longitudinal extent of an elastically deformable, for example, fiber-reinforced material, wherein the deformability by special forms of the channel guide or form the channel walls, z. B. in the manner of a bellows, has been improved. In the latter embodiment, connections between different material areas z. B. by gluing or welding, if not mechanical coupling means in the form of hose brackets o. The like. Be provided. However, both the production of such known air ducts using different manufacturing methods for such different components as well as their installation in the engine compartment of a vehicle is relatively complex and correspondingly expensive.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile bekannter Luftführungskanäle dieser Art zu vermeiden und somit ihre Herstellung und Montage zu vereinfachen.The invention has for its object to avoid the disadvantages of known air ducts of this type and thus to simplify their production and assembly.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäss dadurch, dass beide Kanalteile teleskopartig, relativ zueinander verschiebbar, ineinander greifen und im Bereich ihres gegenseitigen Eingriffs manschettenartig eine profilierte, weichelastische Dichtung an mindestens einem dieser Teile befestigt ist.The solution of this object is achieved according to the invention in that both channel parts telescopically, relative to each other slidably, interlock and in the region of their mutual engagement cuff-like a profiled, soft elastic seal is attached to at least one of these parts.

Vorteilhafte Ausgestaltungen der Erfindung sind der folgenden Beschreibung anhand der Zeichnungen zu entnehmen. Es zeigen in perspektivischer Darstellung:Advantageous embodiments of the invention will be apparent from the following description with reference to the drawings. In a perspective view:

1 einen erfindungsgemässen Luftführungskanal mit einem kühlerseitig zu befestigenden Kanalteil und einem luftfilterseitig zu befestigenden Kanalteil, 1 an inventive air duct with a cooler side to be fastened channel part and an air filter side to be fastened channel part,

2 den kühlerseitigen Kanalteil des Luftführungskanals nach 1, 2 the cooler side duct part of the air duct 1 .

3 einen Teilschnitt des Luftführungskanals nach 1 im Bereich des teleskopartigen Eingriff zwischen seinen beiden Kanalteilen und 3 a partial section of the air duct after 1 in the area of the telescopic engagement between its two channel parts and

4 einen Teilschnitt des Luftführungskanals nach 1 im Bereich des teleskopartigen Eingriffs zwischen seinen beiden Kanalteilen, mit einer anderen Ausführungsform seiner Dichtmanschette und mit vollständig ineinandergeschobener Eingriffsposition zwischen beiden. 4 a partial section of the air duct after 1 in the region of the telescopic engagement between its two channel parts, with another embodiment of its sealing collar and with fully nested engagement position between the two.

Die Formgebung eines erfindungsgemässen Luftführungskanals 1 mit flexibel zusammengefügten, aber unflexiblen, in Kunststoffspritztechnik geformten Kanalteilen 2, 3 entspricht der jeweiligen Anpassung an die Anordnung des Zuströmstutzens eines nichtdargestellten Luftfiltergehäuses relativ zu einem im Bereich des Fahrzeugkühlers vorgesehenen Zuströmkanal, so dass die Formgebung durch die jeweilige Motor- und Fahrzeugkonstruktion vorbestimmt ist.The shape of an inventive air duct 1 with flexibly joined, but inflexible, molded in plastic injection channel parts 2 . 3 corresponds to the respective adaptation to the arrangement of the Zuströmstutzens an unillustrated air filter housing relative to a provided in the region of the vehicle radiator inflow channel, so that the shaping by the respective engine and vehicle construction is predetermined.

Beim dargestellten Ausführungsbeispiel erfolgt diese räumliche Anpassung durch einen grösseren, mehrfach gekrümmten Kanalteil 2, so dass dessen Öffnungsrand 4 nach unten eine in der Darstellung nicht sichtbare Öffnung umschliesst, während der andere Kanalteil 3 teleskopartig von einem ungekrümmten Bereich des gekrümmten Kanalteils 2 umschlossen oder von ihm eingeschlossen ist. Dieser teleskopartige Eingriff ermöglicht eine Längenveränderung des Luftführungskanals 1 durch die er in verkürztem Zustand in den Motorraum eines Fahrzeuges einsetzbar und durch anschliessendes Verlängern fest montierbar ist. Hierzu sind im Bereich des Öffnungsrandes 4 bzw. 5 der Kanalteile 2, 3 Verrastungs- oder Riegelmittel 6, 7, 8 vorgesehen, so dass die Montage und Verbindung mit entsprechenden, im Fahrzeugraum, u. a. am Luftfiltergehäuse vorgesehenen Mitteln auf einfache und schnelle Weise von Hand ausgeführt werden kann.In the illustrated embodiment, this spatial adaptation is done by a larger, multi-curved channel part 2 so that its opening edge 4 encloses down a not visible in the representation opening, while the other channel part 3 telescoping from an unbending portion of the curved channel portion 2 enclosed or enclosed by him. This telescopic engagement allows a change in length of the air duct 1 by which he can be used in a shortened state in the engine compartment of a vehicle and fixed by subsequent extension. These are in the area of the opening edge 4 respectively. 5 the channel parts 2 . 3 Latching or locking means 6 . 7 . 8th provided, so that the assembly and connection with appropriate, provided in the vehicle compartment, including the air filter housing means can be performed in a simple and fast way by hand.

Der anfänglich verkürzte Zustand des Luftführungskanals 1, mit dem er für die Montage zugeliefert wird, kann durch gut zugängliche und somit leicht lösbare Rastmittel 9, 10 gesichert werden, die einerseits an dem Kanalteil 2 und andererseits an dem Kanalteil 3 angeformt sind.The initially shortened condition of the air duct 1 with which it is supplied for assembly, by easily accessible and thus easily releasable locking means 9 . 10 be secured, on the one hand to the channel part 2 and on the other hand, on the channel part 3 are formed.

Um den Kanalteilen 2, 3 bei relativ dünnwandiger Ausführung eine verbesserte Formsteifigkeit zu geben, sind in ihnen in Strömungsrichtung verlaufende, auch der Luftführung dienende Innenwände 11, 12, 13 vorgesehen.To the channel parts 2 . 3 to give an improved stiffness in relatively thin-walled design, are in them in the flow direction, also serving the air guide inner walls 11 . 12 . 13 intended.

Für die gegenseitige Abdichtung und Beweglichkeit der Kanalteile 2, 3 relativ zueinander ist der innere bzw. eingreifende Bereich 14 des Kanalteils 3 von einer profilierten, weichelastischen Dichtmanschette 15 oder 16 umschlossen.For the mutual sealing and mobility of the duct parts 2 . 3 relative to each other is the inner or engaging region 14 of the channel part 3 from a profiled, soft-elastic sealing collar 15 or 16 enclosed.

Entsprechend dem Ausführungsbeispiel der 3 hat diese Manschette 15 fünf parallel zueinander umlaufende, im Querschnitt nach aussen sich verjüngende Dichtrippen 17. Beim Ausführungsbeispiel nach 4 hingegen hat die Manschette 16 drei parallel zueinander umlaufende Dichtlippen 18. Diese weichelastischen Dichtrippen 17 oder Dichtlippen 18 verhindern durch ihre Verformbarkeit eine Übertragung von Schwingungen der Verbrennungskraftmaschine auf die Fahrzeugkarosserie und erleichtern das Einpassen des Luftführungskanals 1 im Motorraum des Fahrzeuges.According to the embodiment of the 3 has this cuff 15 five parallel to each other circumferential, in cross section outwardly tapered sealing ribs 17 , According to the embodiment 4 however, the cuff has 16 three parallel sealing lips 18 , These soft elastic sealing ribs 17 or sealing lips 18 prevent by their deformability, a transmission of vibrations of the internal combustion engine to the vehicle body and facilitate the fitting of the air duct 1 in the engine compartment of the vehicle.

Es versteht sich, dass ein erfindungsgemässer Luftführungskanal mindest zwei teleskopartig ineinander schiebbare Kanalteile 2, 3 aufweist, um für die Montage seine ausreichende Verkürzung zu ermöglichen. Beispielsweise zur Vereinfachung der Herstellung des mehrfach gekrümmten Kanalteiles 2 im Spritzgiessverfahren, kann dieses auch mehrteilig mit z. B. aneinander verrastbaren Teilen hergestellt sein.It is understood that an inventive air duct at least two telescopically slidable channel parts 2 . 3 has to allow for the installation of its sufficient shortening. For example, to simplify the production of the multiply curved channel part 2 In injection molding, this can also be used in several parts with z. B. be made to each other lockable parts.
