Abstract
Description
Die Erfindung betrifft eine Bodengruppe gemäß dem Oberbegriff des Patentanspruchs 1. Bevorzugte Einsatzfälle der Erfindung sind Kraftfahrzeuge vom Cabrio-Typ oder Offroad-Fahrzeuge.The The invention relates to a floor assembly according to the preamble of the claim 1. Preferred applications The invention relates to convertible-type automobiles or off-road vehicles.
Betrachtet man zur Veranschaulichung der der Erfindung zugrunde liegenden Problematik ein Cabrio, so ist der Verzicht auf ein starres Dach bei derartigen Fahrzeugen mit einer beträchtlichen Einbuße an Torsions- und Biegesteifigkeit verbunden. Dieser Verlust kann in ausreichendem Maße nur durch Eingriffe in die Fahrzeugstruktur ausgeglichen werden, die aber den Einsatz von Gleichteilen bei verschiedenen Fahrzeugtypen erschweren. Ähnliche Probleme treten bei Offroad-Fahrzeugen auf, die zwar ein starres Dach haben mögen, an die aber besonders große Anforderungen hinsichtlich Biege- und Torsionssteifigkeit gestellt werden.considered to illustrate the problem underlying the invention a convertible, so is the abandonment of a rigid roof in such Vehicles with a considerable loss connected to torsional and bending stiffness. This loss can sufficiently can only be compensated by interfering with the vehicle structure, but the use of identical parts in different vehicle types difficult. Similar problems occur in off-road vehicles, although they have a rigid roof to like, but especially big ones Requirements with regard to bending and torsional rigidity become.
Bei der Behandlung des geschilderten Problems ist auch zu beachten, dass für die Unterbringung beliebiger Versteifungen innerhalb des eigentlichen Fahrzeugs kaum der erforderliche Platz zur Verfügung steht.at the treatment of the described problem should also be considered that for the accommodation of any stiffeners within the actual Vehicle hardly the required space is available.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Bodengruppe ohne Eingriff in die Fahrzeugstruktur zu schaffen, die eine erhebliche Erhöhung der Biege- und Torsionssteifigkeit des Fahrzeugs zur Folge hat, ohne Eingriffe in die Fahrzeugstruktur zu erfordern.Of the Invention is based on the object, a generic floor pan without creating any intrusion into the vehicle structure, which will significantly increase the Bending and torsional stiffness of the vehicle without To require intervention in the vehicle structure.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausführungen der Erfindung sind Gegenstand der Unteransprüche.The inventive solution this The object is the characterizing features of the main claim, advantageous embodiments The invention are the subject of the dependent claims.
Der erfindungsgemäße Versteifungsmodul nutzt also im Wesentlichen den zur Verfügung stehenden Platz unterhalb des Bodenblechs aus und schafft dort im Prinzip einen geschlossenen Träger, bestehend aus Bodenblech, seitlichen Schwellern und Versteifungsmodul. Bei einem Cabriofahrzeug bildet der Versteifungsmodul gleichsam einen unten am Fahrzeug angeordneten "Dachersatz", während er bei einem ein Dach aufweisenden Offroad-Fahrzeug eine Erhöhung der Steifigkeit zusätzlich zur Steifigkeit des eigentlichen Fahrzeugs bewirkt.Of the uses stiffening module according to the invention So essentially the available space below of the bottom plate and creates there in principle a closed Carrier, consisting from bottom plate, side sills and stiffening module. at In a convertible vehicle, the stiffening module forms, as it were, a bottom one Vehicle arranged "roof replacement" while he in a rooftop offroad vehicle an increase in the Stiffness in addition causes the rigidity of the actual vehicle.
Infolge der Tatsache, dass der Versteifungsmodul praktisch nicht nach unten über die Unterseite der Seitenschweller hinausragt, ist eine störende Beeinträchtigung der Bodenfreiheit des Fahrzeugs vermieden. Ein Zwischenraum zwischen Bodenblech und Versteifungsmodul kann zur Unterbringung von Sandwichstrukturen dienen, die insbesondere die Biegesteifigkeit weiter erhöhen.As a result the fact that the stiffening module is practically not down over the Bottom of the side skirts protrudes, is a disturbing interference the ground clearance of the vehicle avoided. A space between Base plate and stiffening module can be used to accommodate sandwich structures serve, in particular, the flexural rigidity further increase.
Ein weiterer Vorteil der Erfindung ist darin zu sehen, dass der Versteifungsmodul gleichsam von unten an das im Übrigen fertige Fahrzeug bzw. seine Bodenblech-Schweller-Anordnung angesetzt werden kann, so dass spezielle konstruktive Eigenheiten einzelner Fahrzeugtypen keinen Einfluss auf die Gestaltung des Versteifungsmoduls haben, dieser also als Gleichteil für verschiedene Fahrzeugtypen verwendet werden kann.One Another advantage of the invention is the fact that the stiffening module as it were from the bottom, by the way finished vehicle or its bottom plate sill arrangement recognized so that special constructional peculiarities of individual Vehicle types have no influence on the design of the stiffening module have, so this as a common part for different vehicle types can be used.
