Description
Die Erfindung betrifft ein Kraftfahrzeug entsprechend dem Ober begriff des Anspruchs 1.The invention relates to a motor vehicle according to the waiter Concept of claim 1.
Ein derartiges Kraftfahrzeug ist in der DE-OS 35 42 376 darge stellt. Die dort vorgesehenen Kühlluftkanäle erhöhen den Luft widerstand des Fahrzeuges, was inbesondere bei höheren Ge schwindigkeiten zu einem erhöhten Kraftstoffverbrauch und even tuell zu einer höheren Geräuschentwicklung führt. Zur Behebung dieses Nachteils ist es bekannt (DE-OS 38 13 971, 38 13 972) die Kühlluftkanäle durch Klappen zu verschließen, wenn kein Kühlluftbedarf vorliegt. Diese Klappen sind in den als ge schlossene Kanäle ausgebildeten Kühlluftkanälen angeordnet und bilden im geschlossenen Zustand einen Luftwiderstand, da sie von dem Fahrtwind beaufschlagt werden.Such a motor vehicle is shown in DE-OS 35 42 376 Darge poses. The cooling air ducts provided there increase the air resistance of the vehicle, which is particularly true at higher Ge speed to increased fuel consumption and even leads to a higher noise level. To fix this disadvantage is known (DE-OS 38 13 971, 38 13 972) close the cooling air ducts with flaps if none Cooling air is required. These flaps are in the as ge closed channels trained cooling air channels arranged and form a drag when closed, as they be impacted by the wind.
Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeug der gattungsgemäßen Art zu schaffen, das bei nicht benötigter Brem senkühlung einen besseren Luftwiderstandsbeiwert aufweist als die bekannten Kraftfahrzeuge.The invention has for its object a motor vehicle Generic type to create that when the brake is not required cooling has a better drag coefficient than the well-known motor vehicles.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the in the characteristic of Features specified claim 1 solved.
Dadurch, daß die Klappen in ihrer zweiten, die Kühlluftkanäle abdeckenden Stellung mit der Unterseite der Bodenplatte fluch ten, wird jede Beeinträchtigung des Luftwiderstandsbeiwertes durch die Klappen vermieden. The fact that the flaps in their second, the cooling air ducts covering position with the underside of the bottom plate curse any impairment in the drag coefficient avoided by the flaps.
Vorzugsweise bildet die Klappe eine Wand des Kanals. Der Kanal kann dabei von der Klappe und von einem auf der Oberseite der Bodenplatte vorgesehenen Rahmen begrenzt sein, der eine ent sprechende Öffnung in der Bodenplatte umgibt, eine sich in Richtung auf die Bremse vergrößernde senkrechte Erstreckung aufweist und an seinem der Bremse zugewandten rückwärtigen Rahmenteil mit einem Durchbruch versehen ist. Die Klappe hat dabei eine der Innenkontur des Rahmens entsprechende Form, ist innerhalb des Rahmens angeordnet und mit dem von der Bremse abgewandten vorderen Ende des Rahmens scharnierartig verbunden. Die Bodenplatte braucht also nur mit den vorher erwähnten Öff nungen versehen zu werden, da die Kühlluftkanäle nicht wie bei dem gattungsgemäßen Kraftfahrzeug durch Verformung der Boden platte hergestellt werden müssen.The flap preferably forms a wall of the channel. The channel can be from the flap and from one on the top of the Bottom plate provided frame to be limited, the one ent speaking opening in the base plate, one in Vertical extension increasing the direction of the brake has and on its rear facing the brake Frame part is provided with an opening. The flap has is a shape corresponding to the inner contour of the frame arranged within the frame and with that of the brake opposite front end of the frame connected hinge-like. So the bottom plate only needs the previously mentioned public transport to be provided since the cooling air ducts are not as in the generic motor vehicle by deforming the floor plate must be manufactured.
Die Klappe kann an ihrer der Bremse zugewandten Kante eine aufrecht stehende Wand aufweisen, welche den Durchbruch in dem rückwärtigen Rahmenteil in der zweiten Stellung der Klappe abdeckt. Diese Wand der Klappe kann an ihrer freien Kante mit einer Abkantung versehen sein, welche in der zweiten, geschlos senen Stellung der Klappe auf dem rückwärtigen Rahmenteil auf liegt und als Anschlag dient. Im offenen Zustand kann die Klappe mit ihren seitlichen Rändern an nach innen gerichteten Abkantungen des Rahmens anliegen.The flap can be on its edge facing the brake have upright wall, which the breakthrough in the rear frame part in the second position of the flap covers. This wall of the flap can with its free edge be provided with a fold, which in the second, closed open position of the flap on the rear frame part lies and serves as a stop. When open, the Flap with its side edges facing inwards Bend the frame.
Zum verschwenken der Klappe kann ein Kurbelmechanismus vorgese hen sein, der quer zur Längserstreckung der Klappe verläuft und in seitlich am Rahmen vorgesehenen Lagerböcken und dazwischen mit seiner Kurbelkröpfung in einem an der Klappe vorgesehenen Lagerbock gelagert ist.A crank mechanism can be provided to pivot the flap hen that is transverse to the longitudinal extension of the flap and in bearing blocks provided on the side of the frame and in between with its crank crank in one provided on the flap Bearing block is stored.
Der Rahmen und die Klappe können eine Einbaueinheit bilden, die an der Oberseite der Bodenplatte befestigt ist.The frame and the flap can form an installation unit which is attached to the top of the base plate.
Die Ansteuerung der Klappen kann in bekannter Weise mittels eines Stellmotors bei Betätigung des Bremspedals und/oder bei Vorliegen eines Kühlluftbedarfs durch einen auf die Erwärmung der Bremsen ansprechenden Sensor erfolgen, wobei als Korrektur parameter auch die Fahrzeuggeschwindigkeit verwendet werden kann.The control of the flaps can be done in a known manner a servomotor when the brake pedal is actuated and / or at Presence of a cooling air requirement due to the heating the brake responsive sensor take place as a correction parameters the vehicle speed can also be used can.
Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die Zeichnungen beschrieben. Es zeigt:An embodiment of the invention is described below Described with reference to the drawings. It shows:
Fig. 1 eine perspektivische Ansicht des Frontbereichs eines Kraftfahrzeuges von unten, Fig. 1 is a perspective view of the front portion of a motor vehicle from below,
Fig. 2 eine perspektivische Ansicht einer Klappe im geschlosse nen Zustand, Fig. 2 is a perspective view of a flap in the closed-end state,
Fig. 3 eine perspektivische Ansicht der Klappe im geöffneten Zustand, und Fig. 3 is a perspective view of the flap in the open state, and
Fig. 4 und 5 Schnitte entlang Linie A-A bzw. B-B in den Fig. 2 und 3. FIGS. 4 and 5 are sectional views taken along line AA and BB respectively in Figs. 2 and 3.
Das in Fig. 1 in Teilansicht dargestellte Kraftfahrzeug weist im Frontbereich eine Bodenplatte 1 auf, die zur teilweisen Abdeckung des Motorraumes nach unten dient und zur Verbesserung des Luftwiderstandsbeiwertes des Kraftfahrzeuges beiträgt. Die Bodenplatte 1 kann Teil einer nicht gezeigten Frontverkleidung, beispielsweise eines Frontspoilers, sein.The motor vehicle shown in partial view in FIG. 1 has a base plate 1 in the front area, which is used to partially cover the engine compartment downwards and to improve the drag coefficient of the motor vehicle. The base plate 1 can be part of a front cover, not shown, for example a front spoiler.
Die Bodenplatte 1 ist mit Einrichtungen zur Zuführung von Kühl luft zu den Bremsen 3 der Vorderräder 2 versehen. Zu diesem Zweck sind in der Bodenplatte 1 im wesentlichen dreieckige Öffnungen 4 vorgesehen, die sich zu den Bremsen 3 hin verbrei tern. Wie aus den Fig. 2 bis 4 ersichtlich ist, ist auf der Oberseite 5 der Bodenplatte 1 für jede Öffnung 4 ein dreiecki ger Rahmen 6 angebracht, der die Öffnung 4 umgibt und eine sich in Richtung auf die Bremse, also in Fig. 2 und 3 nach rechts zu, vergrößernde senkrechte Erstreckung hat und an seinem der Bremse zugewandten rückwärtigen Rahmenteil 7 mit einem Durch bruch 8 versehen ist. Alternativ könnte der Rahmenteil 7 auch entfallen. Innerhalb des Rahmens 6 ist eine Klappe 9 angeord net, die eine der Innenkontur des Rahmens 6 entsprechende Form hat und die mit dem von der Bremse abgewandten vorderen Ende 10 des Rahmens 6 durch ein Scharnier 11 verbunden ist. Die Klappe 9 ist an ihrem rückwärtigen, der Bremse zugewandten Ende mit einer aufrecht stehenden Wand 12 versehen, welche in der in Fig. 2 dargestellten geschlossenen Stellung den Durchbruch 8 im rückwärtigen Rahmenteil 7 abdeckt. Die Wand 12 weist an ihrer oberen Kante eine Abkantung 13 auf, die in der geschlossenen Stellung der Klappe (Fig. 2) auf dem rückwärtigen Rahmenteil 7 aufliegt. In dieser Stellung fluchtet die Klappe 9 weitgehend mit der Unterseite der Bodenplatte 1, wie aus Fig. 4 ersicht lich ist. Damit wird erreicht, daß bei geschlossener Klappe 9 der Luftwiderstandsbeiwert des Kraftfahrzeuges nicht schlechter ist als der eines Kraftfahrzeuges ohne Kühlluftkanäle. Die kleine Stufe, die durch die Wandstärke der Bodenplatte ent steht, ist dabei vernachlässigbar, zumal sie sich in Fahrtrich tung erstreckt.The base plate 1 is provided with devices for supplying cooling air to the brakes 3 of the front wheels 2 . For this purpose, essentially triangular openings 4 are provided in the base plate 1 , which spread out towards the brakes 3 . As can be seen from FIGS. 2 to 4, a triangular frame 6 is attached to the top 5 of the base plate 1 for each opening 4 , which surrounds the opening 4 and one in the direction of the brake, ie in Fig. 2 and 3 to the right, has an enlarged vertical extension and is provided on its rear-facing frame part 7 with a breakthrough 8 . Alternatively, the frame part 7 could also be omitted. Within the frame 6 , a flap 9 is angeord net, which has a shape corresponding to the inner contour of the frame 6 and which is connected to the front end 10 of the frame 6 facing away from the brake by a hinge 11 . The flap 9 is provided at its rear end facing the brake with an upright wall 12 which, in the closed position shown in FIG. 2, covers the opening 8 in the rear frame part 7 . The wall 12 has at its upper edge a bevel 13 which rests on the rear frame part 7 in the closed position of the flap ( FIG. 2). In this position, the flap 9 is largely aligned with the underside of the base plate 1 , as can be seen from FIG. 4. This ensures that when the flap 9 is closed, the drag coefficient of the motor vehicle is not worse than that of a motor vehicle without cooling air ducts. The small step, which is due to the wall thickness of the base plate, is negligible, especially since it extends in the direction of travel.
Im geöffneten Zustand (Fig. 3 und 5) liegt die Klappe 9 mit ihren seitlichen Rändern an nach innen gerichteten Abkantungen 6a des Rahmens 6 an. Sie bildet die obere Begrenzungswand des Kühlluftkanals 14, der somit von dem Rahmen 6 und der Klappe 9 gebildet wird.In the open state ( Fig. 3 and 5), the flap 9 lies with its lateral edges on inward bends 6 a of the frame 6 . It forms the upper boundary wall of the cooling air duct 14 , which is thus formed by the frame 6 and the flap 9 .
Die Verschwenkung der Klappe zwischen den in Fig. 2 und 3 gezeigten Stellungen erfolgt im Ausführungsbeispiel mit Hilfe eines Kurbelmechanismus 15, der quer zur Längserstreckung der Klappe 9 verläuft und in seitlich am Rahmen 6 vorgesehenen Lagerböcken 16 und dazwischen mit seiner Kurbelkröpfung 17 in einem an der Klappe 9 angebrachten Lagerbock 18 drehbar gela gert ist. Durch Drehen der Kurbel 15 wird die Klappe 9 um die Achse des Scharniers 11 geschwenkt, und zwar aus der geschlos senen Stellung gemäß Fig. 2 durch Drehen der Kurbel 15 im Sinne des Pfeiles 19 in die offene Stellung gemäß Fig. 3 und umge kehrt. Die Drehung der Kurbel 15 erfolgt durch einen nicht dargestellten elektrischen, pneumatischen oder hydraulischen Stellmotor in Abhängigkeit von dem Kühlluftbedarf der Bremsen. Die Klappen 9 sind also im Normalzustand in ihrer geschlosse nen, in Fig. 2 und 4 dargestellten Stellung und sie werden bei Betätigung des Bremspedals, bei Überschreiten einer bestimmten Temperatur der Bremsen und gegebenenfalls zusätzlich in Abhän gigkeit von der Fahrgeschwindigkeit oder von der Stellung des Gaspedals gesteuert, da bei Bergabfahrten, bei denen eine er höhte thermische Belastung der Bremsen auftritt, das Gaspedal in aller Regel nicht betätigt ist.The pivoting of the flap between the positions shown in FIGS. 2 and 3 takes place in the exemplary embodiment with the aid of a crank mechanism 15 which extends transversely to the longitudinal extent of the flap 9 and in bearing blocks 16 provided on the side of the frame 6 and in between with its crank offset 17 in one of the Flap 9 attached bracket 18 is rotatably gela gert. By turning the crank 15 , the flap 9 is pivoted about the axis of the hinge 11 , namely from the closed position shown in FIG. 2 by turning the crank 15 in the direction of arrow 19 in the open position shown in FIG. 3 and vice versa. The crank 15 is rotated by an electric, pneumatic or hydraulic servomotor, not shown, depending on the cooling air requirement of the brakes. The flaps 9 are in their normal state in their closed NEN, shown in Figs. 2 and 4 position and they are when the brake pedal is pressed, when a certain temperature of the brakes is exceeded and, if necessary, additionally in dependence on the driving speed or the position of the accelerator pedal controlled, because when driving downhill, where there is an increased thermal load on the brakes, the accelerator pedal is usually not operated.
Im Ausführungsbeispiel schließt sich an die Bodenplatte 1 eine senkrechte Wand 20 an. Die Öffnungen 4 erstrecken sich in diesem Fall bis zu dieser Wand 20 und setzen sich in einem Ausschnitt 21 in dieser Wand fort, der mit dem Durchbruch 8 im rückwärtigen Rahmenteil 7 übereinstimmt.In the exemplary embodiment, a vertical wall 20 adjoins the base plate 1 . In this case, the openings 4 extend as far as this wall 20 and continue in a cutout 21 in this wall which corresponds to the opening 8 in the rear frame part 7 .
