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 cowlings, as often used for internal combustion engines used in vehicles. In particular, the The present invention relates to a device which is suitable for a Pre-cleaning device for pre-cleaning the combustion air an internal combustion engine is used.

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 pre-cleaning on, with which Dirt particles are removed from the intake air before the Intake air reaches the air filter. Lots Pre-cleaning facilities need a negative pressure or a Vacuum to remove debris from the in the air intake system Incoming fresh air to extract or the fresh air from Clean dirt particles. Exhaust systems were used to provide the required vacuum put. However, such an exhaust system brings a Restriction in the exhaust gas of the internal combustion engine with itself, increases the noise emission and the cost of an exhaust silencer and / or an exhaust pipe. Furthermore, a Shut-off valve required to provide a return of gases higher Prevent temperature in the pre-cleaning device. Finally, hose connectors must be used for high temperatures are suitable.

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.Another possibility is the use of a Intake device for a fan cowl as one Source for the vacuum for a pre-cleaning device Such aspirator is usually by an opening formed in the fan cover, which with Help a hose connection with the pre-cleaning device connected is. A disadvantage of such Intake device is that for this additional Hose connections and hose clamps are needed. Modern agricultural tractors or others Commercial vehicles may require an elongated Trained fan cowl to clear the space between to fill a radiator and a fan.

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 is a Fan cover provided which integrated therein Suction device has.

Thus, the channel is formed when the Duct cover at the top of the Fan cover is mounted or adapted. A first End of the channel ends at an aperture, which at the end of the Fan cover is located near the fan. A second end of the channel is formed bent upward and forms a nozzle or portal on the upper side of the Channel cover. A pre-cleaning device has a Air intake and an air outlet on and is over one Suction connection subjected to negative pressure. If the Pre-cleaning device mounted on the fan cover is, is the suction port on or in the portal or the Nozzle of the duct cover arranged. In other words, that is Intake connection directly with the portal or the nozzle of the Channel cover, without interspersing e.g. a Hose connection is required. The suction port is thus with the air duct and in the fan cowl arranged aperture in communication or connection. That to Operation of the aspirator required vacuum is through provided the air movement generated by the fan, wherein the air movement between the air inlet of the Pre-cleaning device and in the fan cover arranged aperture over the suction port and the air duct he follows.

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 section could have a cross-section like this have a channel between the channel cover and the first section is formed when the channel cover on the first section is attached.
