Abstract
Description
Die Erfindung betrifft eine Anordnung einer wenigstens ein Strömungselement umfassenden Strömungseinrichtung an einem Bauelement eines Kraftwagens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement of a flow device comprising at least one flow element on a component of a motor vehicle according to the preamble of claim 1.
Eine solche Anordnung ist aus der
Es ist Aufgabe der vorliegenden Erfindung, eine Anordnung der eingangs genannten Art bereitzustellen, welche eine besonders vorteilhafte Aerodynamik des Kraftwagens ermöglicht.It is an object of the present invention to provide an arrangement of the type mentioned, which allows a particularly advantageous aerodynamics of the motor vehicle.
Diese Aufgabe wird erfindungsgemäß durch eine Anordnung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by an arrangement with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um eine Anordnung der eingangs genannten Art zu schaffen, welche eine besonders vorteilhafte Aerodynamik des Kraftwagens ermöglicht, umfasst das Strömungselement erfindungsgemäß eine sich zwischen den Seitenflächen erstreckende dreieckförmige Luftleitfläche, welche mit einer Strömungsrichtung der die Luftleitfläche anströmenden Luft einen Anströmwinkel von wenigstens 15 Grad einschließt.In order to provide an arrangement of the type mentioned above, which allows a particularly advantageous aerodynamics of the motor vehicle, the flow element according to the invention comprises a triangular air guide surface extending between the side surfaces, which encloses an inflow angle of at least 15 degrees with a flow direction of the air flowing to the air guide surface.
Durch das Strömungselement ist ein im Wesentlichen dreieckförmiger Störkörper nach Art eines Deltaflügels auf der Oberfläche des Bauelements geschaffen, dessen Luftleitfläche zur Hauptanströmrichtung der Luft um 15° oder mehr angestellt ist. Dadurch bilden sich bei der Umströmung der Luftleitfläche zwei nebeneinander angeordnete Tütenwirbel, welche sich über der Luftleitfläche einrollen und welche einen Unterdruck über der Luftleitfläche und somit Auftrieb erzeugen. Dieser Effekt wird bei der Strömungseinrichtung insoweit genutzt, als die beiden Tütenwirbel die Hauptströmung der Luft führen und zur Fahrzeugmitte des Kraftwagens nach innen ziehen. Dadurch wird der Strömungsnachlauf der Luft insbesondere im Heckbereich des Kraftwagens positiv beeinflusst und sehr gering, woraus ein nur sehr geringer aerodynamischer Widerstand und somit eine vorteilhafte Aerodynamik des Kraftwagens resultieren. Der erläuterte aerodynamische Effekt des Strömungselements ist besonders ausgeprägt, wenn die Seitenflächen und/oder die Luftleitfläche zumindest im Wesentlichen eben ausgebildet sind.By the flow element, a substantially triangular disruptive body is created in the manner of a delta wing on the surface of the device, the air guide is employed to Hauptanströmrichtung the air by 15 ° or more. As a result, two side-by-side arranged bag vortices, which curl over the air guiding surface and which generate a negative pressure over the air guiding surface and thus lift, form during the flow around the air guiding surface. This effect is used in the flow device insofar as the two bag swirls carry the main flow of air and pull the vehicle center of the motor vehicle inwards. As a result, the flow lag of the air is positively influenced in particular in the rear of the motor vehicle and very low, resulting in a very low aerodynamic resistance and thus an advantageous aerodynamics of the motor vehicle result. The explained aerodynamic effect of the flow element is particularly pronounced when the side surfaces and / or the air guide surface are at least substantially planar.
Die Strömungseinrichtung kann dabei im Heckbereich des Kraftwagens und/oder beispielsweise auf der Außenseite eines Daches, einer Fahrzeugsäule und/oder eines Klappenelements, insbesondere einer Heckklappe, als das Bauelement angeordnet sein.The flow device can be arranged as the component in the rear region of the motor vehicle and / or, for example, on the outside of a roof, a vehicle pillar and / or a flap element, in particular a tailgate.
Zur besonders positiven Beeinflussung der Aerodynamik des Kraftwagens kann die Strömungseinrichtung wenigstens ein weiteres Strömungselement oder weitere Strömungselemente umfassen, wobei die bezüglich des ersten Strömungselements geschilderten Ausführungsformen ohne Weiteres auch auf das weitere Strömungselement oder die weiteren Strömungselemente übertragbar sind.For a particularly positive influence on the aerodynamics of the motor vehicle, the flow device may comprise at least one further flow element or further flow elements, wherein the embodiments described with respect to the first flow element are readily transferable to the further flow element or the further flow elements.
