Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einem Bugbereich, in dessen der Fahrbahn zugewandten Unterseite Kanäle zur Zuführung von Kühlluft zu Radbremsen des Kraftfahrzeugs vorgesehen sind.The The invention relates to a motor vehicle with a bow area in whose the carriageway facing bottom channels for delivery provided by cooling air to wheel brakes of the motor vehicle are.

den Luftwiderstand bei nicht benötigter Bremsenkühlung
zu senken, wird in der
Die aus dem Stand der Technik bekannten Kühlluftzuführungen bewirken im Hochleistungsbereich, insbesondere bei für den Hochgeschwindigkeitsbereich ausgelegten Sportwagen, eine nur unzureichende Bremsenkühlung.The known from the prior art cooling air supply effect in the high-performance range, in particular for the sports car designed the high-speed area, one only insufficient brake cooling.
Aufgabe der vorliegenden Erfindung ist es, eine Kühlluftzuführung zu Radbremsen eines Kraftfahrzeugs bereitzustellen, die unter Vermeidung der aus dem Stand der Technik bekannten Nachteile eine effizientere und bedarfsgerechte Bremsluftzufuhr bewirkt.task It is the object of the present invention to provide a cooling air supply to provide wheel brakes of a motor vehicle, while avoiding the disadvantages known from the prior art a more efficient and needs-based brake air supply causes.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des unabhängigen Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Patentansprüche.These The object is achieved by the features of independent claim 1. Advantageous Further developments of the invention are the subject of the dependent Claims.
Ein Kraftfahrzeug der eingangs genannten Art weist in der Unterseite seines Bugbereichs Kanäle zur Zuführung von Kühlluft zu den Radbremsen des Kraftfahrzeugs auf, wobei diese Kanäle jeweils ein geschlossenes Profil aufweisen und jeweils um eine Drehachse zwischen einer ersten Stellung und einer zweiten Stellung schwenkbar ausgebildet sind, wobei die Kanäle in der ersten Stellung mit einer Bodenfläche im Frontbereich des Kraftfahrzeugs im Wesentlichen fluchten, und wobei die Kanäle in der zweiten Stellung die Zuführung von Kühlluft zu den Radbremsen ermöglichen. Erfindungsgemäß kann ein geschlossenes Einlassprofil in den Luftstrom bzw. in die Stauluft im Unterbodenbereich des Fahrzeugs ausgeschwenkt werden. Derart kann in der zweiten Stellung ein deutlich höherer Luftmassenstrom an die Radbremsen transportiert werden als bei bekannten Lösungen mit schwenkbaren Klappen. Erfindungsgemäß ist der Luftwiderstand insbesondere auch in der zweiten Stellung geringer als bei geöffneten Luftleitkanälen, wie sie aus dem Stand der Technik bekannt sind.One Motor vehicle of the type mentioned points in the bottom its bow area channels for supplying cooling air to the wheel brakes of the motor vehicle, these channels each having a closed profile and each about an axis of rotation pivotable between a first position and a second position are formed, wherein the channels in the first position with a bottom surface in the front region of the motor vehicle are substantially aligned, and wherein the channels in the second Position the supply of cooling air to the wheel brakes enable. According to the invention, a closed Inlet profile in the air flow or in the ram air in the underbody area be swung out of the vehicle. Such can be in the second position a significantly higher air mass flow to the wheel brakes be transported as in known solutions with swiveling Flaps. According to the invention, the air resistance especially in the second position less than open Air ducts, as known from the prior art.
Mit Vorteil können die Kanäle jeweils ein geschlossenes Profil in Form eines Rechtecks aufweisen. Derart kann ein besonders hoher Luftmassenstrom an die Radbremsen geführt werden.With Advantage, the channels each have a closed Profile in the form of a rectangle. That's a special way high air mass flow to the wheel brakes are performed.
Mit Vorteil können die Drehachsen der Kanäle jeweils in der hinteren Hälfte des jeweiligen Kanals angeordnet sein, d. h. die Drehachsen der Kanäle können in der vom Bug des Kraftfahrzeugs abgewandten Hälfte des jeweiligen Kanals angeordnet sein. Derart steht dem Ausschwenken des Einlassbereichs des Kanals nach unten nur eine relativ geringe Bewegung des Auslassbereichs nach oben gegenüber. Dies ist konstruktiv günstig für die Auslegung des Radkastens im Auslassbereich des Kanals.With Advantage can the axes of rotation of the channels respectively arranged in the rear half of the respective channel be, d. H. the axes of rotation of the channels can in the remote from the bow of the motor vehicle half of the respective Channel can be arranged. Such is the pivoting of the inlet area the channel down only a relatively small movement of the outlet upwards opposite. This is structurally favorable for the design of the wheel arch in the outlet area of the Channel.
Mit Vorteil können die Kanäle jeweils eine Krümmung aufweisen, derart, dass in der zweiten Stellung eine Luftführung nach oben hin ermöglicht wird. Durch die derart in der zweiten Stellung nach oben gerichtete und gekrümmte untere Begrenzungswand eines Kanals wird zusätzliche Kühlluft aus der Unterbodenströmung an die dem Kanal zugeordnete mindestens eine Radbremse geführt. Dadurch, dass die Kühlluft weiter nach oben gelenkt wird, wird sie zielgerichteter der mindestens einen Radbremse zugeführt.With Advantageously, the channels each have a curvature such that in the second position an air duct is made possible upwards. By so in the second position upward and curved lower Boundary wall of a channel will provide additional cooling air the underbody flow to the channel associated with at least a wheel brake out. Because the cooling air is directed further upward, it will be more targeted of at least fed to a wheel brake.
Mit Vorteil kann hinter den Kanälen jeweils mindestens eine Umlenkvorrichtung zum Zuführen von Kühlluft zu den Radbremsen vorgesehen sein. Dies ermöglicht eine gezielte und im Zusammenwirken der Kanäle mit den jeweiligen Umlenkvorrichtungen aerodynamisch besonders günstige Luftzuführung zu den Radbremsen.With Advantage can behind the channels at least one Deflection device for supplying cooling air be provided the wheel brakes. This allows a targeted and in cooperation of the channels with the respective deflection devices aerodynamically very favorable air supply to the wheel brakes.
Mit Vorteil können die Kanäle im Wesentlichen in Fahrzeuglängsrichtung angeordnet sein, wobei die Abweichung einer Mittelachse eines Kanals von der Fahrzeuglängsachse jeweils nicht mehr als 30° beträgt.With Advantageous channels can essentially in the vehicle longitudinal direction be arranged, wherein the deviation of a central axis of a channel of the vehicle longitudinal axis is not more than 30 °.
Mit Vorteil können die Kanäle symmetrisch zur Fahrzeuglängsachse angeordnet sein.With Advantage, the channels can be symmetrical to the vehicle longitudinal axis be arranged.
In vorteilhafter Weiterbildung der Erfindung kann eine Steuervorrichtung vorgesehen sein, die mit Stellvorrichtungen zum Schwenken der Kanäle gekoppelt sein kann.In an advantageous embodiment of the invention a control device may be provided which may be coupled with adjusting devices for pivoting the channels.
