Description

Die vorliegende Erfindung betrifft eine Ansaugvorrichtung für eine Vorreinigungseinrichtung in Verbindung mit einer Ventilatorverkleidung, wie sie häufig für Verbrennungsmotoren bei Fahrzeugen eingesetzt werden. Insbesondere betrifft die vorliegende Erfindung eine Vorrichtung, welche für eine Vorreinigungseinrichtung zum Vorreinigen der Verbrennungsluft eines Verbrennungsmotors zum Einsatz kommt. Im Konkreten betrifft die vorliegende Erfindung eine Ansaugvorrichtung, welche einer solchen Vorreinigungseinrichtung einen Unterdruck bzw. ein Vakuum zur Verfügung stellt.The present invention relates to a suction device for a pre-cleaning device in conjunction with a fan cowling, as they are often used for internal combustion engines in vehicles. In particular, the present invention relates to a device which is used for a pre-cleaning device for pre-cleaning the combustion air of an internal combustion engine. Specifically, the present invention relates to a suction device, which provides a vacuum or a vacuum to such a pre-cleaning device.

Lufteinlasssysteme für Verbrennungsmotoren von landwirtschaftlichen oder industriellen Nutzfahrzeugen weisen üblicherweise Vorreinigungseinrichtungen auf, mit welchen Schmutzpartikel von der Ansaugluft entfernt werden, bevor die Ansaugluft zu dem Luftfilter gelangt. Viele Vorreinigungseinrichtungen benötigen einen Unterdruck bzw. ein Vakuum, um Schmutzpartikel aus der in das Lufteinlasssystem eintretenden Frischluft herauszuziehen bzw. die Frischluft von Schmutzpartikeln zu reinigen. Auspuffsauganlagen wurden verwendet, um das erforderliche Vakuum zur Verfügung zu stellen. Eine solche Auspuffsauganlage bringt jedoch eine Beschränkung in dem Abgas des Verbrennungsmotors mit sich, erhöht die Geräuschemission und die Kosten eines Auspuff-Schalldämpfers und/oder eines Auspuffrohrs. Weiterhin ist ein Sperrventil erforderlich, um einen Rückfluss von Gasen hoher Temperatur in die Vorreinigungseinrichtung zu verhindern. Schließlich müssen Schlauchverbinder verwendet werden, die für hohe Temperaturen geeignet sind.Air intake systems for internal combustion engines of agricultural or industrial utility vehicles usually have pre-purification devices with which dirt particles are removed from the intake air before the intake air reaches the air filter. Many pre-cleaning facilities require a negative pressure or a vacuum in order to extract dirt particles from the fresh air entering the air intake system or to clean the fresh air from dirt particles. Exhaust systems were used to provide the required vacuum. However, such an exhaust system entails a restriction in the exhaust gas of the internal combustion engine, increases the noise emission and the cost of an exhaust muffler and / or an exhaust pipe. Furthermore, a check valve is required to prevent backflow of high temperature gases into the pre-cleaner. Finally, hose connectors that are suitable for high temperatures must be used.

Eine andere Möglichkeit stellt die Verwendung einer Ansaugvorrichtung für eine Ventilatorverkleidung als eine Quelle für den Unterdruck für eine Vorreinigungseinrichtung dar. Eine solche Ansaugvorrichtung ist üblicherweise durch eine Öffnung in der Ventilatorverkleidung gebildet, welche mit Hilfe einer Schlauchverbindung mit der Vorreinigungseinrichtung verbunden ist. Ein Nachteil einer solchen Ansaugvorrichtung ist der, dass hierfür zusätzliche Schlauchverbindungen und Schlauchklemmen benötigt werden. Moderne landwirtschaftliche Traktoren oder andere Nutzfahrzeuge benötigen unter Umständen eine länglich ausgebildete Ventilatorverkleidung, um den Freiraum zwischen einem Kühler und einem Lüfter auszufüllen. Ein Beispiel eines solches systems ist in der US-5427502 gezeigt.Another possibility is to use a fan cowl suction device as one Such a suction device is usually formed by an opening in the fan cowl, which is connected by means of a hose connection with the pre-cleaning device. A disadvantage of such a suction device is that this additional hose connections and hose clamps are needed. Modern agricultural tractors or other utility vehicles may require an elongated fan shroud to fill the space between a radiator and a fan. An example of such a system is in US 5427502 shown.

Die der Erfindung zugrunde liegende Aufgabe wird darin gesehen, eine Ansaugvorrichtung der eingangs genannten Art anzugeben und weiterzubilden, durch die die vorgenannten Probleme überwunden werden. Insbesondere soll eine Ansaugvorrichtung angegeben und weitergebildet werden, die kostengünstiger produziert werden kann und welche vorzugsweise weniger Einzelteile aufweist. Eine solche Ansaugvorrichtung sollte insbesondere kompatibel zu bekannten bzw. bestehenden Herstellungs- und Fertigungstechniken sein.The object underlying the invention is seen to provide and further develop a suction device of the type mentioned, by which the above-mentioned problems are overcome. In particular, a suction device should be specified and further developed, which can be produced more cheaply and which preferably has fewer individual parts. Such a suction device should be particularly compatible with known or existing manufacturing and manufacturing techniques.

Die Aufgabe wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.The object is achieved by the teaching of claim 1. Further advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Die erfindungsgemäße Ansaugvorrichtung ist für eine Vorreinigungseinrichtung in Verbindung mit einer Ventilatorverkleidung geeignet. Die Vorreinigungseinrichtung weist einen Ansauganschluss auf. Die Ventilatorverkleidung ist zwischen einem Lüfter und einem Kühler angeordnet. Die Ansaugvorrichtung weist einen Kanal auf, welcher an einer Oberfläche der Ventilatorverkleidung vorgesehen ist. Der Kanal kommuniziert bzw. verbindet zwischen einem - insbesondere in Form einer Düse ausgebildeten - Portal und einer Apertur, die an der Ventilatorverkleidung in der Nähe des Lüfters angeordnet ist. Die Vorreinigungseinrichtung ist an der Ventilatorverkleidung derart anbringbar, dass der Ansauganschluss über das Portal mit dem Kanal in unmittelbarer Verbindung steht. Der erforderliche Unterdruck bzw. das erforderliche Vakuum zum Ansaugen für die Vorreinigungseinrichtung wird von einem von dem Lüfter erzeugten Luftfluss bzw. Luftstrom durch den Kanal zur Verfügung gestellt.The suction device according to the invention is suitable for a pre-cleaning device in conjunction with a fan cowl. The pre-cleaning device has a suction port. The fan cowl is located between a fan and a radiator. The Aspirator has a channel which is provided on a surface of the fan cowl. The channel communicates or connects between a - formed in particular in the form of a nozzle - portal and an aperture, which is arranged on the fan cowl in the vicinity of the fan. The pre-cleaning device can be attached to the fan cowling in such a way that the suction port is in direct communication with the port via the portal. The required negative pressure or the required vacuum for sucking for the pre-cleaning device is provided by a generated by the fan air flow or air flow through the channel.

Gemäß einer besonders bevorzugten Ausführungsform ist eine Ventilatorverkleidung vorgesehen, welche eine darin integrierte Ansaugvorrichtung aufweist. Die Ventilatorverkleidung weist einen oberen und einen unteren Abschnitt auf. Der obere Abschnitt ist komplementär zu dem unteren Abschnitt ausgebildet, so dass hierdurch im zusammengefügten Zustand ein Kanal zwischen dem Lüfter und dem Kühlmodul bzw. den Kühler des Fahrzeugs gebildet ist. Der obere Abschnitt der Ventilatorverkleidung weist einen Kanal auf, welcher von einem Luftkanalabschnitt in der Ventilatorverkleidung und einem hierzu ähnlichen Luftkanalabschnitt in einer Kanalabdeckung gebildet ist. Somit wird der Kanal gebildet, wenn die Kanalabdeckung an dem oberen Abschnitt der Ventilatorverkleidung montiert bzw. angepasst ist. Ein erstes Ende des Kanals endet an einer Apertur, welche am Ende der Ventilatorverkleidung in der Nähe des Lüfters angeordnet ist. Ein zweites Ende des Kanals ist nach oben gebogen ausgebildet und bildet eine Düse bzw. ein Portal an der oberen Seite der Kanalabdeckung. Eine Vorreinigungseinrichtung weist einen Lufteinlass und einen Luftauslass auf und wird über einen Ansauganschluss mit Unterdruck beaufschlagt. Wenn die Vorreinigungseinrichtung an der Ventilatorverkleidung montiert ist, ist der Ansauganschluss an bzw. in dem Portal oder der Düse der Kanalabdeckung angeordnet. Mit anderen Worten ist der Ansauganschluss unmittelbar mit dem Portal oder der Düse der Kanalabdeckung verbunden, ohne dass dazwischen z.B. eine Schlauchverbindung erforderlich ist. Der Ansauganschluss ist somit mit dem Luftkanal und der in der Ventilatorverkleidung angeordneten Apertur in Kommunikation bzw. Verbindung. Das zum Betrieb der Ansaugvorrichtung erforderliche Vakuum wird durch die von dem Lüfter erzeugte Luftbewegung bereitgestellt, wobei die Luftbewegung zwischen dem Lufteinlass der Vorreinigungseinrichtung und der in der Ventilatorverkleidung angeordneten Apertur über den Ansauganschluss und den Luftkanal erfolgt. Da die Vorreinigungseinrichtung unmittelbar an den Luftkanal anpassbar bzw. adaptierbar ist, sind keine zusätzlichen Unterdruckschläuche oder Schlauchklemmen erforderlich. Daher kann in ganz besonders vorteilhafter Weise Bauraum unter einer Motorhaube gespart werden.According to a particularly preferred embodiment, a fan cowl is provided, which has a suction device integrated therein. The fan cowling has an upper and a lower section. The upper portion is formed complementary to the lower portion, so that in the assembled state, a channel between the fan and the cooling module or the radiator of the vehicle is formed. The upper portion of the fan shroud has a channel formed by an air duct section in the fan shroud and a similar air duct section in a duct cover. Thus, the channel is formed when the channel cover is fitted to the upper portion of the fan cowl. A first end of the channel terminates at an aperture located at the end of the fan cowl near the fan. A second end of the channel is formed bent upward and forms a nozzle or a portal on the upper side of the Channel cover. A pre-cleaning device has an air inlet and an air outlet and is pressurized via a suction with negative pressure. When the pre-cleaner is mounted to the fan shroud, the suction port is located at the portal or nozzle of the channel shroud. In other words, the suction port is directly connected to the portal or the nozzle of the channel cover, without intervening, for example, a hose connection is required. The suction port is thus in communication with the air passage and the aperture located in the fan shroud. The vacuum required to operate the aspirator is provided by the air movement generated by the fan, the movement of air between the air inlet of the prepurifier and the aperture located in the fan shroud being via the aspiration port and the air channel. Since the pre-cleaning device is directly adaptable or adaptable to the air duct, no additional vacuum hoses or hose clamps are required. Therefore, space under a hood can be saved in a particularly advantageous manner.

Bevorzugt weist die Ventilatorverkleidung einen ersten Abschnitt und einen zweiten Abschnitt auf. Der erste und der zweite Abschnitt könnte im zusammengesetzten Zustand eine vollständige Ventilatorverkleidung bilden. Eine Montage der beiden Abschnitte aneinander könnte dadurch ermöglicht werden, dass der erste und der zweite Abschnitt jeweils mindestens einen Flansch aufweist, wobei der Flansch des ersten Abschnitts komplementär zum Flansch des zweiten Abschnitts ausgebildet ist.The fan cover preferably has a first section and a second section. The first and second sections, when assembled, could form a complete fan cowl. An assembly of the two sections together could be made possible in that the first and the second section each have at least one flange, wherein the flange of the first section is formed complementary to the flange of the second section.

Bevorzugt weist der erste Abschnitt der Ventilatorverkleidung einen darin ausgebildeten Luftkanal auf. Auch der Kanal bzw. der Luftkanal könnte zweiteilig ausgebildet sein. So wäre es denkbar, dass der Luftkanal einen in dem ersten Abschnitt ausgebildeten ersten Kanalabschnitt und einen in einer Kanalabdeckung ausgebildeten zweiten Kanalabschnitt aufweist.Preferably, the first section of the fan cowling has an air channel formed therein. Also, the channel or the air duct could be formed in two parts. Thus, it would be conceivable that the air channel has a first channel section formed in the first section and a second channel section formed in a channel cover.

Nun könnte jeder Kanalabschnitt einen Querschnitt derart aufweisen, dass ein Kanal zwischen der Kanalabdeckung und dem ersten Abschnitt ausgebildet ist, wenn die Kanalabdeckung an dem ersten Abschnitt angebracht ist. Der Gesamtquerschnitt des Kanals könnte kreisförmig oder ellipsenförmig sein. Im Konkreten könnte die Kanalabdeckung an jeder Seite des Kanalabschnitts Flansche aufweisen, welche zu dazu komplementär ausgebildeten Oberflächen des ersten Abschnitts der Ventilatorverkleidung korrespondieren, so dass die Kanalabdeckung passend oder dichtend an dem ersten Abschnitt der Ventilatorverkleidung befestigbar ist.Now, each channel portion may have a cross section such that a channel is formed between the channel cover and the first portion when the channel cover is attached to the first portion. The overall cross section of the channel could be circular or elliptical. Concretely, the channel cover on each side of the channel portion could have flanges corresponding to complementary surfaces of the first portion of the fan shroud, such that the channel cover can be fastened to the first portion of the fan shroud.

Besonders bevorzugt weist der Kanal eine Passage mit einem im Wesentlichen kreisförmigen Querschnitt auf, und erstreckt sich zwischen der Kanalabdeckung und dem ersten Abschnitt der Ventilatorverkleidung. Der Kanal verbindet den Ansauganschluss mit der an der Ventilatorverkleidung ausgebildeten Apertur.More preferably, the channel has a passage with a substantially circular cross-section, and extends between the channel cover and the first portion of the fan cowl. The channel connects the suction port with the aperture formed on the fan shroud.

Die Kanalabdeckung könnte eine Düse aufweisen, welche das Portal zu dem Kanal bildet, wenn die Kanalabdeckung an dem ersten Abschnitt der Ventilatorverkleidung montiert ist.The channel cover could include a nozzle which forms the portal to the channel when the channel cover is mounted to the first portion of the fan cowl.

Zur Befestigung der Vorreinigungseinrichtung an der Ventilatorverkleidung könnte der erste Abschnitt der Ventilatorverkleidung mindestens einen Befestigungsvorsprung aufweisen, so dass der Ansauganschluss der Vorreinigungseinrichtung kommunizierend zu dem Portal angeordnet ist, welches durch die Düse der Kanalabdeckung gebildet sein könnte, wenn die Vorreinigungseinrichtung an den Befestigungsvorsprüngen montiert ist.To attach the pre-cleaning device on the fan cowling, the first section of the fan cowling could have at least one fastening projection such that the suction port of the pre-cleaner is arranged to communicate with the gantry which could be formed by the nozzle of the duct cover when the pre-cleaner is mounted to the mounting bosses.

Die Ventilatorverkleidung könnte aus einem thermoplastischen oder duroplastischen Material geformt sein.The fan shroud could be molded from a thermoplastic or thermosetting material.

Ein erstes Ende 44 des Kanalabschnitts 28 endet an einem Ende der Kanalabdeckung 30, wodurch im montierten Zustand der Kanalabdeckung 30 die kreisförmige Apertur 34 durch die Ventilatorverkleidung 10 vervollständigt wird. Ein Mundstück oder eine Düse 46 ist an der Oberseite der Kanalabdeckung 30 vorgesehen. Die Düse 46 kommuniziert mit dem zweiten Ende 48 des Kanalabschnitts 28 in einem Bereich, in welchem der Kanalabschnitt 26 des oberen Abschnitts 12 der Ventilatorverkleidung 10 nach oben gebogen ausgebildet ist. Dementsprechend weist der Luftkanal 24 einen Kanal mit einem im Wesentlichen kreisförmigen Querschnitt auf, der sich von der Apertur 34 nahe des Lüfters 22 und der oben angeordneten Düse 46 der Kanalabdeckung 30 erstreckt, wenn die Kanalabdeckung 30 an ihrem vorgesehenen Ort befestigt ist.A first end 44 of the channel portion 28 terminates at one end of the channel cover 30, whereby in the assembled state of the channel cover 30, the circular aperture 34 is completed by the fan cowling 10. A mouthpiece or nozzle 46 is provided at the top of the channel cover 30. The nozzle 46 communicates with the second end 48 of the channel portion 28 in a region in which the channel portion 26 of the upper portion 12 of the fan shroud 10 is formed bent upward. Accordingly, the air channel 24 has a channel with a substantially circular cross-section extending from the aperture 34 near the fan 22 and the top-mounted nozzle 46 of the channel cover 30 when the channel cover 30 is secured in place.

Eine Vorreinigungseinrichtung 50 für die Ansaugluft für den Verbrennungsmotor umfasst einen Lufteinlass bzw. einen Ansaugstutzen 52, einen Ansauganschluss 54 und einen Luftabzug bzw. einen Luftauslass 56. Im Betrieb wird Luft durch den Ansaugstutzen 52 angezogen und Schmutzpartikel werden von der Ansaugluft entfernt bzw. die Ansaugluft wird gereinigt und die gereinigte Luft tritt durch den mit einem nicht gezeigten Lufteinlass eines ebenfalls nicht gezeigten Verbrennungsmotors verbundenen Luftauslass 56 aus der Vorreinigungseinrichtung 50 aus. Die Saugwirkung für die Vorreinigungsvorrichtung 50 wird von dem vom Lüfter 22 erzeugten Vakuum bzw. Unterdruck über den Ansauganschluss 54 bereitgestellt, was im Folgenden beschrieben wird.A pre-cleaner 50 for the intake air for the internal combustion engine comprises an air intake 52, a suction port 54 and an air exhaust 56. In operation, air is drawn through the intake manifold 52 and dirt particles are removed from the intake air and the intake air is cleaned and the purified air exits through the connected to an air inlet, not shown, of an internal combustion engine, also not shown, air outlet 56 from the pre-cleaning device 50. The suction for the pre-cleaning device 50 is provided by the vacuum generated by the fan 22 via the suction port 54, which will be described below.

Es sind zwei Befestigungsvorsprünge 58 an dem oberen Abschnitt 12 der Ventilatorverkleidung 10 vorgesehen. Die Befestigungsvorsprünge 58 korrespondieren zu Befestigungslaschen 60, welche am Gehäuse der Vorreinigungseinrichtung 50 angeordnet sind. Hiermit kann die Vorreinigungseinrichtung 50 an der Ventilatorverkleidung 10 mit Hilfe entsprechender Befestigungsmittel befestigt werden. Wenn die Befestigungslaschen 60 zu den Befestigungsvorsprünge 58 ausgerichtet sind, ist der Ansauganschluss 54 derart positioniert, dass er gleitend in die Düse 46 der Kanalabdeckung 30 eingeführt werden kann. Dementsprechend steht der Ansauganschluss 54 kommunizierend mit dem Luftkanal 24 und der Apertur 34 in Verbindung. Der für die Vorreinigungseinrichtung 50 erforderliche Unterdruck wird durch eine von dem Lüfter 22 verursachte Luftbewegung bewirkt, wobei die Luftbewegung sich zwischen dem Ansaugstutzen 52 der Vorreinigungseinrichtung 50 und der Apertur 34 der Ventilatorverkleidung 10 über den Ansauganschluss 54 und den Luftkanal 24 erstreckt. Da die Vorreinigungseinrichtung 50 unmittelbar an dem Luftkanal 24 der Ventilatorverkleidung 10 angebracht bzw. angepasst ist, sind keine zusätzlichen, für Unterdruck geeignete Ansaugschläuche oder Schlauchschellen erforderlich, wodurch in vorteilhafter Weise weniger Bauraum unter der Motorhaube des Fahrzeugs benötigt wird.Two fastening projections 58 are provided on the upper portion 12 of the fan cowl 10. The fastening projections 58 correspond to fastening tabs 60, which are arranged on the housing of the pre-cleaning device 50. Hereby, the pre-cleaning device 50 can be attached to the fan cowling 10 by means of appropriate fastening means. When the attachment tabs 60 are aligned with the attachment protrusions 58, the aspiration port 54 is positioned to be slidably inserted into the nozzle 46 of the channel cover 30. Accordingly, the suction port 54 communicates with the air passage 24 and the aperture 34 in communication. The negative pressure required for the pre-cleaning device 50 is caused by an air movement caused by the fan 22, wherein the air movement between the intake port 52 of the pre-cleaning device 50 and the aperture 34 of the fan cowl 10 via the suction port 54 and the Air duct 24 extends. Since the pre-cleaning device 50 is mounted or adapted directly to the air duct 24 of the fan cowl 10, no additional, suitable for negative pressure suction hoses or hose clamps are required, which advantageously less space under the hood of the vehicle is needed.
