Abstract
Bodenaufbau an einem Kraftfahrzeug-Heck, mit einem oberen Boden und einem dazu beabstandeten unteren Boden, und mit einer Abgasanlage, die benachbart zum Bodenaufbau verläuft, dadurch gekennzeichnet, daß der Bodenaufbau (1) zum einen einen Verstauraum (6) für Kraftfahrzeugteile (7, 8, 9) aufweist und daß der obere Boden (5) des Bodenaufbaus (1), der den Boden des Verstauraumes (6) bildet, durch Stege (11, 12, 13; 16, 17, 18) von dem unteren Boden (10) beabstandet ist, daß unterhalb des Verstauraumes (6) ausgebildete Seitenwände (25, 26) zusammen mit den Böden (5, 10) und den Stegen (11, 12, 13; 16, 17, 18) Strömungskanäle (27, 28; 35, 36) bilden, die an ihrem vorderen Ende (14) Einlaßöffnungen (29, 30; 37, 38) und an ihrem hinteren, heckseitigen Ende (15) sowie an den Seitenwänden (25, 26) Auslaßöffnungen (31, 32; 39, 40) aufweisen.Floor structure at a motor vehicle rear, with an upper floor and a lower floor spaced therefrom, and with an exhaust system, which runs adjacent to the floor structure, characterized in that the floor structure (1) on the one hand a storage compartment (6) for motor vehicle parts (7, 8, 9) and in that the upper floor (5) of the floor structure (1), which forms the bottom of the storage space (6), by webs (11, 12, 13, 16, 17, 18) of the lower floor (10 ) is spaced, that below the Verstauraumes (6) formed side walls (25, 26) together with the bottoms (5, 10) and the webs (11, 12, 13, 16, 17, 18) flow channels (27, 28, 35 , 36), which at their front end (14) inlet openings (29, 30, 37, 38) and at its rear, rear end (15) and on the side walls (25, 26) outlet openings (31, 32, 39, 40).
Description
Die Erfindung betrifft einen Bodenaufbau an einem Kraftfahrzeug-Heck gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a floor structure on a motor vehicle tail according to the preamble of Claim 1.
Es

der
Aufgabe der Erfindung ist es, einen Bodenaufbau an einem Kraftfahrzeug-Heck zu schaffen, mit dem die beim Fahren an der Kraftfahrzeugunterseite auftretende Luftströmung nutzbar ist.task The invention is a floor structure on a motor vehicle tail to create, with the occurring when driving on the vehicle underside airflow is usable.
Diese Aufgabe wird bei einem erfindungsgemäßen Bodenaufbau durch die Merkmale des Anspruchs 1 gelöst.These Task is in a floor construction according to the invention by the features of claim 1.
Der erfindungsgemäße Bodenaufbau erfüllt in vorteilhafter Weise drei Funktionen. Durch die Anordnung und Ausbildung des Bodenaufbaus unterhalb des Kofferraumbodens wird ein Verstauraum für Kraftfahrzeug-Teile oder Aggregate geschaffen. So kann in diesem Verstauraum ein Reserverad, eine Fahrzeugbatterie, ein Flüssigkeitsbehälter zur Reinigung einer Heckscheibe und/oder das Bordwerkzeug untergebracht werden. Durch die Ausbildung von Strömungskanälen an der Unterseite des Verstauraumes ist es möglich, daß die auf eine Hinterachse wirkenden Auftriebskräfte verringert werden und daß die am Fahrzeugboden entlangströmende Luft über die Strömungskanäle zur Kühlung einer Abgasanlage nutzbar ist.Of the Floor structure according to the invention fulfilled in advantageously three functions. By arrangement and training the floor structure below the trunk floor is a storage space for motor vehicle parts or aggregates created. So can in this storage space a spare tire, a vehicle battery, a liquid container for Cleaning a rear window and / or the tool kit housed become. Through the formation of flow channels at the bottom of the storage space Is it possible, that the on a rear axle acting buoyancy forces are reduced and that the am Vehicle floor flowing along Air over the Flow channels for cooling a Exhaust system is usable.
In einer vorteilhaften Ausführungsform wird bei einem nicht ausreichenden Luftstrom zur Kühlung der Abgasanlage ein Ventilator oder mehrere Ventilatoren oder Gebläse dazugeschaltet, die über die seitlichen Strömungskanäle für eine ausreichende Kühlung der Abgasanlage sorgen. Diese Ventilatoren sind vorteilhafterweise in Abhängigkeit von der Temperatur der Abgasanlage gesteuert. Ein solcher Ventilator könnte beispielsweise im Radhaus, im Bereich der Radnabe, angeordnet sein.In an advantageous embodiment is at an insufficient air flow for cooling the Exhaust system one fan or several fans or blower connected, the above the lateral flow channels for a sufficient cooling the exhaust system provide. These fans are advantageous dependent on controlled by the temperature of the exhaust system. Such a fan could be arranged for example in the wheel arch, in the region of the wheel hub.
Die Unteransprüche betreffen vorteilhafte Ausgestaltungen des erfindungsgemäßen Bodenaufbaus.The under claims relate to advantageous embodiments of the floor structure according to the invention.
Von besonderem Vorteil ist, daß eine Luftspaltisolation gegen Wärmeeinwirkung durch eine Wärmequelle wie die Abgasanlage oder die Bremsen durch eine doppelschalige oder doppelwandige Bauweise des Bodenaufbaus ermöglicht wird.From It is particularly advantageous that an air gap insulation against heat through a heat source like the exhaust system or the brakes through a double shell or the double-walled construction of the floor structure is made possible.
In einer vorteilhaften Ausführungsform ist der Bodenaufbau aus einem Kunststoff hergestellt. Dadurch ist eine preisgünstige Herstellung des Bodenaufbaus möglich. Vorzugsweise ist der erfindungsgemäße Bodenaufbau aus einer oberen Schale aus Kunststoff gebildet, die den Verstauraum zur Aufnahme, Befestigung und Ablage des Reserverads und der Batterie dient. Eine untere Schale mit den durch die Seitenwände und die Luftleitstege gebildeten Strömungskanäle ist mit der oberen Schale durch die bekannten Befestigungsmöglichkeiten, wie z. B. Verkleben, Ultraschall-Schweißen und/oder Verschrauben, verbunden. Durch diese Konstruktion wird eine einfache zweischalige Bauweise erreicht, die zusätzlich eine höhere Steifigkeit des Bodenaufbaus bewirkt.In an advantageous embodiment The floor structure is made of a plastic. This is a cheap Production of the floor structure possible. Preferably, the floor structure according to the invention is made of an upper Shell made of plastic, which accommodates the storage space, Attachment and storage of the spare wheel and the battery is used. A lower shell with the flow channels formed by the side walls and the Luftleitstege is with the upper shell by the known attachment options, such as B. bonding, ultrasonic welding and / or screwing, connected. This construction becomes a simple bivalve Construction achieved in addition a higher one Rigidity of the soil structure causes.
