Abstract
Description
Die Erfindung betrifft eine Luftansaugvorrichtung nach dem Oberbegriff des Anspruchs 1 und ein Kraftfahrzeug nach dem Anspruch 5.The invention relates to an air intake device according to the preamble of claim 1 and a motor vehicle according to claim 5.
Aus der
Ferner sind zur Verringerung von Ansauggeräuschen vorgesehene Auftulpungen, die um eine Ansaugöffnung verlaufen, bekannt.Further, provided to reduce Ansauggeräuschen provided bulges, which extend around an intake opening known.
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine Ansaugung von Fließwasser kostengünstig zu vermeiden. Diese Aufgabe wird durch eine erfindungsgemäße Luftansaugvorrichtung entsprechend dem Anspruch 1 und ein Kraftfahrzeug entsprechend dem Anspruch 5 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of inexpensively avoiding an intake of flowing water. This object is achieved by an air intake device according to the invention according to claim 1 and a motor vehicle according to claim 5. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einer Luftansaugvorrichtung eines Kraftfahrzeugs, mit zumindest einem Ansaugrohr, das zumindest eine Ansaugöffnung und eine um die Ansaugöffnung verlaufende Auftulpung aufweist, die zur Verringerung von Ansauggeräuschen einen Ansaugquerschnitt vergrößert.The invention relates to an air intake device of a motor vehicle, with at least one intake pipe, which has at least one intake opening and an upturn extending around the intake opening, which increases a Ansaugquerschnitt to reduce intake noise.
Es wird vorgeschlagen, dass das Ansaugrohr zumindest einen umlaufenden Steg aufweist, der zur Wasserabscheidung von Fließwasser beabstandet zu der Auftulpung außenseitig angeordnet ist. Dadurch kann eine Auftulpung an der Ansaugöffnung zur Ansauggeräuschminimierung mit einem Steg zur Wasserabscheidung kombiniert werden, wodurch ein Randbereich an der Ansaugöffnung bereitgestellt werden kann, durch den Strömungsgeräusche reduziert und ein Ansaugen von Fließwasser verhindert werden können. Durch den umlaufenden Steg kann verhindert werden, dass das Fließwasser, welches sich beispielsweise an einem Gehäuse, insbesondere an einem Luftfiltergehäuse, bildet und/oder sammelt, in einen Bereich der Auftulpung und damit in einen Bereich hoher Strömungsgeschwindigkeiten gelangt und angesaugt wird. Das Fließwasser kann vor der Ansaugöffnung abgeschieden werden, bevor dieses aufgrund von Strömungsgeschwindigkeiten um die Auftulpung in die Ansaugöffnung gezogen wird. Das Fließwasser kann an dem Steg entlang vor der Auftulpung abfließen und abtropfen. Dadurch kann eine Ansaugung von Fließwasser kostengünstig vermieden werden. Unter einer „Auftulpung” soll insbesondere ein Aufspreizen und/oder ein Aufweiten eines die Ansaugöffnung begrenzenden Ansaugöffnungsrands verstanden werden. Durch die Auftulpung ist der Ansaugöffnungsrand vorzugsweise tulpenähnlich ausgeformt. Unter „umlaufen” soll insbesondere um einen Umfang verlaufend verstanden werden.It is proposed that the intake pipe has at least one circumferential web, which is arranged on the outside for the water separation of running water spaced from the bulge. Thereby, a bulge at the suction port for minimizing intake noise can be combined with a web for water separation, whereby an edge portion can be provided at the suction port, can be reduced by the flow noise and suction of flowing water can be prevented. By the circumferential ridge can be prevented that the flow of water, which forms, for example, on a housing, in particular on an air filter housing, and / or collects, reaches a region of the bulge and thus in a range of high flow velocities and is sucked. The flow water can be deposited in front of the suction opening before it is drawn into the suction opening around the bulge due to flow rates. The running water can flow off the web before the bulge and drip off. As a result, an intake of flowing water can be inexpensively avoided. A "bulge" should in particular be understood to mean a spreading and / or a widening of an intake opening edge delimiting the intake opening. Due to the bulge, the Ansaugöffnungsrand is preferably shaped tulip similar. By "circulate" should be understood in particular to a degree running.
Um die Fließwasserabscheidung zu verbessern, wird weiter vorgeschlagen, dass das Ansaugrohr zumindest einen quer zum umlaufenden Steg angeordneten Quersteg aufweist, der beabstandet zu der Auftulpung außenseitig angeordnet ist, wodurch das an dem umlaufenden Steg fließende Fließwasser an dem Quersteg zum Abtropfen gezwungen werden kann.In order to improve the flow-water separation, it is further proposed that the intake pipe has at least one transversely arranged to the circumferential web crosspiece which is spaced from the bulge arranged on the outside, whereby the flowing at the circumferential web flowing water can be forced to the crossbar for dripping.
Insbesondere ist es vorteilhaft, wenn der Quersteg an einer der Auftulpung abgewandten Seite des umlaufenden Stegs angebunden ist, wodurch verhindert werden kann, dass das abtropfende Fließwasser angesaugt wird.In particular, it is advantageous if the transverse web is connected to a side remote from the bulge side of the circumferential ridge, whereby it can be prevented that the dripping water flow is sucked.
Um das Ansaugen des abtropfenden Fließwassers besonders zuverlässig zu vermeiden, ist es weiter vorteilhaft, wenn die Auftulpung eine Verlängerung aufweist, die in zumindest eine Richtung entlang einer Ansaugquerschnittsebene gerichtet ist, wodurch ein Abstand zwischen der Ansaugöffnung und des abtropfenden Fließwassers vergrößert werden kann. Unter einer „Verlängerung” soll in diesem Zusammenhang insbesondere verstanden werden, dass die Auftulpung einen Bereich aufweist, der sich im Vergleich zu einem anderen Bereich der Auftulpung in die zumindest eine Richtung entlang der Ansaugquerschnittsebene weiter erstreckt. Unter einer „Ansaugquerschnittsebene” soll insbesondere eine Ebene verstanden werden, in der der Ansaugquerschnitt angeordnet ist.In order to avoid sucking the draining running water particularly reliably, it is further advantageous if the bulge has an extension which is directed in at least one direction along an intake cross-sectional plane, whereby a distance between the suction opening and the draining running water can be increased. In this context, an "extension" should be understood in particular to mean that the bulge has a region which, in comparison to another region of the bulge, extends further in the at least one direction along the intake cross-sectional plane. An "intake cross-section plane" is to be understood in particular as meaning a plane in which the intake cross-section is arranged.
Weiter wird ein Kraftfahrzeug, insbesondere ein Nutzkraftfahrzeug, mit einer Brennkraftmaschine und einer zur Luftversorgung der Brennkraftmaschine vorgesehenen, erfindungsgemäßen Luftansaugvorrichtung vorgeschlagen. Dadurch kann verhindert werden, dass Fließwasser in einen Brennraum der Brennkraftmaschine angesaugt wird, wodurch ein Motorschaden verhindert werden kann.Furthermore, a motor vehicle, in particular a commercial vehicle, with an internal combustion engine and an air intake device provided according to the invention for supplying air to the internal combustion engine is proposed. Thereby, it can be prevented that flowing water is sucked into a combustion chamber of the internal combustion engine, whereby engine damage can be prevented.
