Description

Chassis und/oder Tragstruktur eines Kraftfahrzeugs Chassis and / or support structure of a motor vehicle
Die Erfindung betrifft ein Chassis und/oder eine Tragstruktur eines Kraftfahrzeugs, insbesondere eines Personenkraftwagens, nach dem Oberbegriff des Anspruchs 1.The invention relates to a chassis and / or a support structure of a motor vehicle, in particular a passenger car, according to the preamble of claim 1.
Chassis sind übliche Baugruppen zur Gewährleistung der Strukturfestigkeit bei herkömmlichen Fahrzeugen und dementsprechend weit verbreitet. Sie weisen mehrere, zumeist aus Formstahl gefertigte, mit Befestigungsmitteln, wie z.B. Schrauben oder Schweißpunkten, miteinander verbundene Längs- und Querträger auf. Bei Kraftfahrzeugen dienen sie hauptsächlich der Aufnahme Antriebseinrichtung, Achsen und Fahrzeugkarosserie.Chassis are common assemblies to ensure the structural strength of conventional vehicles and are accordingly widespread. They have several, mostly made of shaped steel, with fasteners, such as Screws or welding spots, connected longitudinal and cross members. In the case of motor vehicles, they are used primarily to accommodate the drive device, axles and vehicle body.
Je nach Bauart des Chassis werden teilweise auch Hohlprofile verwendet, die zumeist jedoch aus Gründen des Korrosionsschutzes geschlossen ausgebildet sind und aufgrund des höheren Widerstandsmomentes von Hohlprofilen im Vergleich zu Vollprofilen relativ zu Masse eingesetzt werden.Depending on the design of the chassis, hollow profiles are also used in some cases, but these are mostly closed for reasons of corrosion protection and are used relative to mass due to the higher section modulus of hollow profiles compared to solid profiles.
Aus der DE 40 07 771 AI ist eine Vorrichtung zur Unterdrückung des Sprühnebelaustritts im Radbereich von Kraftfahrzeugen, insbesondere von Lastkraftwagen, bekannt. Hierbei ist vorgesehen, entweder zwischen einem Längsträger des Fahrzeugchassis oder zwischen einem Kotflügel und dem Fahrzeugchassis entlang der Längsträger eine Saugleitung zu verlegen, die nach dem Venturi-Prinzip eine Saugwirkung erzeugt und den Sprühnebelaustritt vermindert. In der DE 40 07 771 AI ist zwar eine separat verlegte Saugleitung erwähnt, darüber hinaus ist jedoch nichts offenbart.From DE 40 07 771 AI a device for suppressing the spray discharge in the wheel area of motor vehicles, in particular trucks, is known. In this case, it is provided either to lay a suction line between a side member of the vehicle chassis or between a fender and the vehicle chassis along the side members, which suction line uses the Venturi principle and reduces the spray discharge. In DE 40 07 771 AI Although a separately installed suction line is mentioned, nothing else is disclosed.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, eine alternative Bauart für ein Chassis und/oder eine Tragstruktur anzugeben.The present invention is concerned with the problem of specifying an alternative design for a chassis and / or a support structure.
Dieses Problem wird durch den Gegenstand des unabhängigen Anspruchs gelost. Vorteilhafte Ausfuhrungsformen sind Gegenstand der abhangigen Ansprüche.This problem is solved by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, ein Chassis und/oder eine Tragstruktur eines Kraftfahrzeugs als Hohlkammerplattenstruktur auszubilden. Durch die Hohlkammerplattenstruktur wird, im Gegensatz zu einem konventionellen Fahrzeugrohbau mit sehr wenigen Hohlräumen (z.B. Schweller), ein relativ großflächiges Kanalsystem geschaffen, wodurch sich neue Möglichkeiten ergeben, die Luftmassenstrome, die funktionsbedingt (z.B. Kuhlluft, Fahrgastzellenbeluftung) durch ein Fahrzeug geleitet werden, ganz gezielt an bestimmten Fahrzeugstellen ausströmen zu lassen. Hierdurch kann beispielsweise eine Fahrzeugumstromung positiv beeinflusst werden, indem beispielsweise ein Teil einer Motorraumabluft durch einen Hohlkammerboden zum Fahrzeugheck geleitet wird und dort einen Fahrzeugnachlauf so beeinflusst bzw. verkleinert, dass der Luftwiderstand und der Fahrzeugauftrieb reduziert und bei Vollheckfahrzeugen die Verschmutzung der Heckscheibe verringert wird.The invention is based on the general idea of designing a chassis and / or a support structure of a motor vehicle as a hollow-chamber plate structure. In contrast to a conventional vehicle bodyshell with very few cavities (e.g. sills), the hollow-chamber panel structure creates a relatively large-area duct system, which opens up new possibilities for the air mass flows that are passed through a vehicle due to its function (e.g. cooling air, passenger compartment ventilation) to let out specifically at certain vehicle locations. In this way, for example, a flow around the vehicle can be positively influenced, for example by leading part of an engine exhaust air through a hollow chamber floor to the rear of the vehicle and influencing or reducing vehicle caster there in such a way that air resistance and vehicle buoyancy are reduced, and in the case of full-rear vehicles the pollution of the rear window is reduced.
Desweiteren ist der Spielraum durch die in der Hohlkammerplattenstruktur vorhandenen Stromungskanale zur Be- und Entlüftung einer Fahrgastzelle wesentlich großer und es lassen sich voraussichtlich heute noch notwendige, separat verbaute Stromungskanale einsparen, wodurch sich die Produktionskosten verringern. Zudem wird durch eine weitgehend freie Gestaltung und Anordnung der Be- und Entlüftung der Fahrgastzelle eine Reduzierung von Turschließkraften durch einen schnelleren Druckabbau in der Fahrgastzelle erreicht.Furthermore, the scope for flow and ventilation in a passenger compartment is considerably greater due to the flow channels in the hollow-chamber plate structure, and it is likely that the separately installed flow channels that are still required can be saved today, which reduces production costs reduce. In addition, a largely free design and arrangement of the ventilation of the passenger compartment results in a reduction in door closing forces by means of faster pressure reduction in the passenger compartment.
Zweckmäßig kann vorgesehen sein, dass die Hohlkammerplatten als Leichtmetallelemente und/oder als Kunststoffelemente ausgebildet sind. Leichtmetalle und Kunststoffe sind Werkstoffe, die im allgemeinen ein geringes Gewicht und eine leichte Be- arbeitbarkeit aufweisen. Im Hinblick auf die zunehmend wichtigere Ressourcenschonung s nd leichte Materialien besonders im Fahrzeugbau von wesentlicher Bedeutung. Ein geringes Gesamtgewicht ermöglicht den Einsatz einer leistungsschwacheren Antriebseinrichtung bei gleichem Fahrkomfort und ermöglicht damit eine Senkung des Spritverbrauchs.It can expediently be provided that the hollow chamber plates are designed as light metal elements and / or as plastic elements. Light metals and plastics are materials that are generally light in weight and easy to machine. In view of the increasingly important conservation of resources, light materials are particularly important in vehicle construction. A low overall weight enables the use of a less powerful drive device with the same driving comfort and thus enables a reduction in fuel consumption.
Besonders im Bereich der Kunststoffe und der Verbundwerkstoffe, wie z.B. Glasfaser- oder Carbonfaser verstärkte Kunststoffe, besteht noch deutliches Entwicklungspotenzial . Die Leistungsfähigkeit dieser faserverstärkten Kunststoffe ist beispielsweise aus dem Rennsport (Mono-Cock) bekannt.Especially in the field of plastics and composite materials, such as Glass fiber or carbon fiber reinforced plastics, there is still significant development potential. The performance of these fiber-reinforced plastics is known, for example, from racing (mono-cock).
Entsprechende einer besonders gunstigen Ausfuhrungsform der erfindungsgemaßen Losung kann vorgesehen sein, dass die Hohlkammerplatten als Strangpressprofile und/oder als gebaute Profile, insbesondere aus Blech, ausgebildet sind. Strangpressprofile sind heutzutage einfach und kostengünstig herzustellen und erlauben eine individuelle Nachbearbeitung eines ansonsten gleichen Strangpressprofll-Grundkorpers . Dadurch besteht die Möglichkeit verschiedene Fahrzeugchassis für verschiedene Fahrzeugtypen lediglich durch eine entsprechende Nachbearbeitung, von im Grundzustand gleichen Strangpress- Profllplatten, herzustellen, wodurch eine wesentliche Vereinfachung der Produktion erreicht wird. Gebaute Hohlkammerprofile bieten dagegen den Vorteil, eine stark individuell orientierte Fertigung von Fahrzeugchassis zu ermöglichen. Besonders bei Fahrzeugen im Hochpreisssegment sind oftmals durch entsprechende Kundenwünsche individuelle Abänderungen des Fahrzeugchassis erforderlich. Diese Abänderungen können bei gebauten Profilen bereits im Bauzustand berücksichtigt werden und verhindern somit ein aufwändiges Nacharbeiten eines Standardprofils.Corresponding to a particularly favorable embodiment of the solution according to the invention, it can be provided that the hollow chamber panels are designed as extruded profiles and / or as built profiles, in particular made of sheet metal. Nowadays, extruded profiles are easy and inexpensive to manufacture and allow individual reworking of an otherwise identical extruded basic body. As a result, there is the possibility of producing different vehicle chassis for different vehicle types only by appropriate reworking, of extruded profiled sheets that are the same in the basic state, which considerably simplifies production. Constructed hollow chamber profiles, on the other hand, offer the advantage of enabling a highly individually oriented manufacture of vehicle chassis. In the case of vehicles in the high-price segment in particular, individual modifications to the vehicle chassis are often required due to customer requirements. These changes can already be taken into account in the case of built profiles and thus prevent time-consuming reworking of a standard profile.
Eine besonders vorteilhafte Ausführungsform der erfindungsgemäßen Lösung ist dadurch gekennzeichnet, dass durch Klappen an einer Ein- bzw. Ausströmöffnung die Strömungskanäle steuerbar ausgebildet sind. Eine gezielte Steuerung des Luftdurchlasses durch die Strömungskanäle bietet den Vorteil, bestimmte Eigenschaften des Fahrzeugs, wie z.B. den Andruck des Fahrzeugs auf dem Untergrund zu beeinflussen. Beispielsweise können die Klappen so angesteuert sein, dass bei höheren Geschwindigkeiten ein größerer Luftdurchsatz ermöglicht wird als bei kleiner Geschwindigkeit. Die im Fahrzeugchassis verlaufenden Strömungskanäle und die an den Ausströmöffnungen der Strömungskanäle angebrachte Klappen sowie die Form der Ein- bzw. Ausströmöffnungen bewirken dabei Effekte ähnlich jenen eines Spoilers, wodurch ein Auftrieb des Fahrzeugs verringert wird. Die Durchströmung der Kanäle kann durch Einsatz von Gebläsen unterstützt werden.A particularly advantageous embodiment of the solution according to the invention is characterized in that the flow channels are designed to be controllable by flaps on an inflow or outflow opening. A targeted control of the air passage through the flow channels offers the advantage of certain properties of the vehicle, such as to influence the pressure of the vehicle on the surface. For example, the flaps can be controlled in such a way that a higher air throughput is made possible at higher speeds than at low speeds. The flow channels running in the vehicle chassis and the flaps attached to the outflow openings of the flow channels as well as the shape of the inflow and outflow openings bring about effects similar to those of a spoiler, as a result of which the buoyancy of the vehicle is reduced. The flow through the channels can be supported by using fans.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus den zugehörigen Figurenbeschreibungen anhand der Zeichnungen.Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures with reference to the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombi- nationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden in den nachfolgenden Beschreibungen näher erläutert, wobei sich gleiche Bezugszeichen auf gleiche oder ähnliche oder funktional, gleiche Bauteile beziehen.It goes without saying that the features mentioned above and those yet to be explained below not only in the combination indicated in each case, but also in other combinations nations or alone can be used without departing from the scope of the present invention. Preferred exemplary embodiments of the invention are shown in the drawings and are explained in more detail in the following descriptions, the same reference numerals referring to the same or similar or functionally identical components.
Die Figuren zeigen schematisch,The figures show schematically
Fig. 1 eine Schrägansicht eines erfindungsgemäßen Fahrzeugchassis,1 is an oblique view of a vehicle chassis according to the invention,

Fig. 3 einen möglichen Verlauf von Strömungskanälen durch das Fahrzeugchassis.Fig. 3 shows a possible course of flow channels through the vehicle chassis.
Entsprechend Fig. 1 ist ein Chassis 6 bzw. eine Tragstruktur eines im übrigen nicht dargestellten Kraftfahrzeugs 19 ausgeführt. Das Chassis β weist mehrere plattenartige Einzelelemente, wie z.B. eine Hohlkammerbodenplatte 1 (im folgenden vereinfacht auch Hohlkammerplatte 1 genannt), vertikale Hohlkammerplatten 4 sowie die vertikale Hohlkammerplatten 4 verbindende Hohlkammerplatten 15 auf. Die Hohlkammerplatten 1,4 und 15 bilden zusammen mit einem Fahrgestell 14 die Tragstruktur des Kraftfahrzeugs 19. Die einzelnen Hohlkammerplatten 1,4,15 sind in geeigneter Weise, z.B. durch Schweißen und/oder Kleben miteinander verbunden und versteifen das Chassis 6. Gemäß der Fig. 2 ist beispielhaft ein Ausschnitt aus der Hohlkammerplatte 15 dargestellt. Es sei ausdrucklich erwähnt, dass der Ausschnitt gemäß Fig. 2 auch auf die anderen aufgeführten Hohlkammerplatten 1,4 übertragbar ist.According to FIG. 1, a chassis 6 or a support structure of a motor vehicle 19, which is otherwise not shown, is designed. The chassis β has a plurality of plate-like individual elements, such as, for example, a hollow-chamber floor plate 1 (hereinafter also referred to simply as hollow-chamber plate 1), vertical hollow-chamber plates 4 and hollow-chamber plates 15 connecting the vertical hollow-chamber plates 4. The hollow chamber plates 1, 4 and 15 together with a chassis 14 form the supporting structure of the motor vehicle 19. The individual hollow chamber plates 1, 4, 15 are connected to one another in a suitable manner, for example by welding and / or gluing, and stiffen the chassis 6. According to FIG. 2, a section of the hollow chamber plate 15 is shown as an example. It should be expressly mentioned that the cutout according to FIG. 2 can also be transferred to the other hollow chamber plates 1, 4 listed.
Die Hohlkammerplatte 15 ist aus einer oberen Platte 16 und einer unteren Platte 17 aufgebaut, die durch, zwischen der o- beren Platte 16 und der unteren Platte 17 orthogonal zu den beiden Plattenebenen verlaufende Trennwände 12, verbunden ist. Aufgrund der Trennwände 12 werden jeweils voneinander getrennte, parallel verlaufende Stromungskanale 10, die einen im wesentlichen rechteckigen Querschnitt aufweisen, erzeugt. Die Anzahl der Trennwände 12 bestimmt dabei die Anzahl sowie den Querschnitt der einzelnen Stromungskanale 10.The hollow chamber plate 15 is constructed from an upper plate 16 and a lower plate 17, which is connected by partition walls 12 which run between the upper plate 16 and the lower plate 17 orthogonal to the two plate levels. Due to the dividing walls 12, mutually separate, parallel flow channels 10, which have an essentially rectangular cross section, are produced. The number of partition walls 12 determines the number and the cross section of the individual flow channels 10.
Wie in Fig. 2 dargestellt tritt eine Luftströmung 5 durch eine Emstromoffnung 2 auf der einen Seite der Hohlkammerplatte 15 in den Stromungskanal 10 ein und auf der anderen Seite durch eine Ausströmöffnung 3 wieder aus. Dabei ist denkbar, einzelne Stromungskanale 10 zur Luftströmung 5 zu nutzen, wahrend andere Stromungskanale 10 unbenutzt bleiben. Zudem ist auch eine Umlenkung der Luftströmung 5 durch eine Öffnung 13 aus der Ebene der Hohlkammerplatte 15 heraus möglich, um diese beispielsweise in eine vertikal daran anschließende Hohlkammerplatte 4 weiterzuleiten.As shown in FIG. 2, an air flow 5 enters the flow channel 10 through an airflow opening 2 on one side of the hollow chamber plate 15 and exits again through an outflow opening 3 on the other side. It is conceivable to use individual flow channels 10 for air flow 5, while other flow channels 10 remain unused. In addition, a deflection of the air flow 5 through an opening 13 out of the plane of the hollow chamber plate 15 is also possible, for example in order to pass it on to a vertically adjoining hollow chamber plate 4.
Die Anordnung der Öffnung 13 ist dabei nicht auf die obere bzw. die untere Platte 16, 17 beschrankt, sie kann auch in die Trennwände 12 integriert sein, wodurch eine Verbindung zwischen den einzelnen Stromungskanalen 10 geschaffen wird. Durch die Anordnung einer oder mehrere Offnungen 13 in einer oder mehrerer Trennwände 12 in Verbindung mit einer in Stro- mungsrichtung davor oder dahinter gelegenen und den Querschnitt des Stromungskanals 10 verschließenden Sperrwand 18, ist es möglich, den für die Luftströmung 5 zur Verfugung stehenden Querschnitt und damit die Stromungsgeschwindigkeit zu beeinflussen.The arrangement of the opening 13 is not limited to the upper or lower plate 16, 17, it can also be integrated into the partition walls 12, thereby creating a connection between the individual flow channels 10. By arranging one or more openings 13 in one or more partition walls 12 in connection with a barrier wall 18 located upstream or downstream in the direction of flow and closing the cross section of the flow channel 10, it is possible to influence the cross section available for the air flow 5 and thus the flow rate.
So ist denkbar, dass die Luftströmung 5 durch eine einzelne Einstromoffnung 2 in den Stromungskanal 10 eintritt und dort aufgrund von zumindest einer in der Trennwand 12 vorhandenen Öffnung 13 auf zumindest zwei Stromungskanale 10 verteilt wird, und damit durch mehrere Ausströmöf nungen 3 wieder aus der Hohlkammerplatte 15 austritt. Durch eine Veränderung des Stromungsguerschnitts wahrend des Stromungsvorgangs kann somit erreicht werden, dass eine an der Einstromoffnung 2 schnelle Luftströmung 5 beim Austritt aus der Hohlkammerplatte 15 durch mehrere Ausströmöffnungen 3 eine wesentlich geringere Geschwindigkeit aufweist.It is conceivable that the air flow 5 enters the flow channel 10 through a single inflow opening 2 and is distributed there to at least two flow channels 10 due to at least one opening 13 in the partition 12, and thus through several outflow openings 3 again from the hollow chamber plate 15 exits. By changing the flow cross-section during the flow process it can thus be achieved that a rapid air flow 5 at the inflow opening 2 has a significantly lower speed when it emerges from the hollow chamber plate 15 through a plurality of outflow openings 3.
Auch der umgekehrte Fall, d.h. Eintritt der Luftströmung 5 durch mehrere Einstromoffnungen 2 und ein Zusammenfassen von mehreren Stromungskanalen 10 durch in den Trennwanden 12 integrierte Offnungen 13 zu lediglich einem Stromungskanal 10 mit einer Ausströmöffnung 3 und damit eine Erhöhung der Stromungsgeschwindigkeit ist möglich. Verstärkt wird dieser Effekt durch die orthogonal zur Stromungsrichtung, den Querschnitt des Stromungskanals 10 verschließende Sperrwande 18, die in Stromungsrichtung nach der Öffnung 13 angeordnet sind.The reverse case, i.e. Entry of the air flow 5 through a plurality of inflow openings 2 and a combination of a plurality of flow channels 10 through openings 13 integrated in the partition walls 12 to only one flow channel 10 with an outflow opening 3 and thus an increase in the flow rate is possible. This effect is reinforced by the barrier walls 18 which close the cross section of the flow channel 10 and are arranged orthogonally to the flow direction and which are arranged after the opening 13 in the flow direction.
Entsprechend Fig. 3 ist ein möglicher Verlauf der Stromungskanale 10 durch das Kraftfahrzeug 19 ausgeführt. Im Bereich eines vorderen Teils des Kraftfahrzeugs 19 und im Bereich der Hohlkammerbodenplatte 1 sind Einstromoffnungen 2 vorgesehen.According to FIG. 3, a possible course of the flow channels 10 through the motor vehicle 19 is carried out. Inflow openings 2 are provided in the area of a front part of the motor vehicle 19 and in the area of the hollow-chamber floor panel 1.
Die entgegen einer gewohnlichen Fahrtrichtung auftretende Luftströmung 5, trifft nach Eintritt in den Motorraum 21 auf den Kuhler 9, umströmt die Antriebseinrichtung 8 und gelangt in Fahrtrichtung nach einem vorderen Fahrzeugrad 7 durch eine in der Hohlkammerbodenplatte 1 angeordnete Einstromoffnung 2 in den Stromungskanal 10 und wird bodenseitig unterhalb einer Fahrgastzelle 20 in Richtung eines hinteren Fahrzeugrades 22 gefuhrt. Der Stromungskanal 10 ist dabei im Bereich des hinteren Fahrzeugrades 22 entlang eines Radlaufes angeordnet und wird in Fahrtrichtung nach dem hinteren Fahrzeugrad 22 auf Hohe einer nicht dargestellten Stoßstange zum Fahrzeugheck 23 gefuhrt .The air flow 5, which occurs against a normal direction of travel, hits the radiator 9 after entering the engine compartment 21, flows around the drive device 8 and arrives in the direction of travel after a front vehicle wheel 7 through an inflow opening 2 arranged in the hollow-chamber floor plate 1 into the flow channel 10 and is guided on the floor side below a passenger compartment 20 in the direction of a rear vehicle wheel 22. The flow channel 10 is arranged in the area of the rear vehicle wheel 22 along a wheel arch and is guided in the direction of travel after the rear vehicle wheel 22 to the height of a bumper (not shown) to the rear of the vehicle 23.
Denkbar ist hierbei ist auch, dass der Stromungskanal 10 im Bereich des hinteren Fahrzeugrads 22 in Fahrtrichtung nach dem hinteren Fahrzeugrad 22 eine Einstromoffnung 2 besitzt, wodurch bewirkt wird, dass ein eventuell bei Nasse auftretender Spruhnebel im Radlauf abgesaugt und zum Heck 23 des Fahrzeugs 19 transportiert wird. Am Fahrzeugheck 23 gelangt die im Stromungskanal 10 fließende Luftströmung 5 durch die Ausströmöffnung 3 in die Umgebung.It is also conceivable here that the flow channel 10 in the area of the rear vehicle wheel 22 has an inflow opening 2 in the direction of travel after the rear vehicle wheel 22, which causes a spray mist that may occur when wet to be sucked off in the wheel arch and transported to the rear 23 of the vehicle 19 becomes. At the rear of the vehicle 23, the air flow 5 flowing in the flow channel 10 reaches the surroundings through the outflow opening 3.
Ein weiterer Stromungskanal 10 beginnt mit einer Einstromoff- nung 2' unter einer Motorhaube 24 des Kraftfahrzeugs 19 und besitzt eine Ausströmöffnung 3', durch die die Luftströmung 5 in die Fahrgastzelle 20 gelangt. Im in Fahrtrichtung gesehen hinteren Bereich der Fahrgastzelle 20 ist zumindest eine weitere Einstromoffnung 2'' zu einem weiteren Stromungskanal 10 angeordnet, welcher die Fahrgastzelle 20 mit dem Fahrzeugheck 23 verbindet. Dieser weitere Stromungskanal 10 besitzt am Fahrzeugheck 23 eine weitere Ausströmöffnung 3 ' X Hierdurch ist eine kontinuierliche und vorbestimmbare Be- und Entlüftung der Fahrgastzelle 20 gewahrleistet.Another flow channel 10 begins with an inflow opening 2 'under a bonnet 24 of the motor vehicle 19 and has an outflow opening 3' through which the air flow 5 reaches the passenger compartment 20. In the rear area of the passenger compartment 20, as seen in the direction of travel, at least one further inflow opening 2 ″ to another flow duct 10 is arranged, which connects the passenger compartment 20 to the rear of the vehicle 23. This further flow channel 10 has a further outflow opening 3 ′ X at the rear of the vehicle 23. This ensures continuous and predeterminable ventilation of the passenger compartment 20.
Durch die vorbestimmte Anordnung der Ausströmöffnungen 3 bzw. 3'' am Fahrzeugheck 23 kann eine Verminderung der Verschmutzung des Fahrzeughecks 23 sowie eine Reduzierung des Auf- tπebs des Kraftfahrzeugs 19 erreicht werden. Gleichzeitig reduzieren sich die aus einem Umstromungsvorgang des Kraftfahrzeugs 19 resultierenden Luftwirbel, was den Treibstoffverbrauch verringert.The predetermined arrangement of the outflow openings 3 or 3 ″ on the rear of the vehicle 23 can reduce the pollution of the rear of the vehicle 23 and reduce the opening. tπebs of the motor vehicle 19 can be reached. At the same time, the air vortices resulting from a flow around the motor vehicle 19 are reduced, which reduces fuel consumption.
Zusammenfassend lasst sich die erfindungsgemaße Bauweise wie folgt charakterisieren:In summary, the construction method according to the invention can be characterized as follows:
Durch die Tragstruktur aus Hohlkammerplatten 1,4,15 wird ein großflächiges System von Stromungskanalen 10 geschaffen, wodurch die Luftstrome 5 gezielt durch oder um das Fahrzeug 19 geleitet werden. Der Luftwiderstand und der Fahrzeugauftrieb werden reduziert und die Verschmutzung des Fahrzeughecks 23 wird verringert.A large-area system of flow channels 10 is created by the support structure made of hollow chamber plates 1, 4, 15, as a result of which the air streams 5 are directed through or around the vehicle 19. The air resistance and vehicle lift are reduced and the pollution of the rear of the vehicle 23 is reduced.
Desweiteren lassen sich heute noch verbaute separate Luf- tungskanale zum Teil einsparen, wodurch sich die Produktionskosten verringern. Zudem wird eine Verbesserung der Be- und Entlüftung der Fahrgastzelle 20 und eine Reduzierung der Tur- schließkrafte durch einen schnelleren Druckabbau in der Fahrgastzelle 20 erreicht.Furthermore, built-in separate air ducts can still be partially saved, which reduces production costs. In addition, an improvement in the ventilation of the passenger compartment 20 and a reduction in the door closing forces are achieved by a faster pressure reduction in the passenger compartment 20.
Die Hohlkammerplatten 1,4,15 können dabei auch als Leichtmetall- und/oder als Kunststoffelemente ausgebildet sein, wodurch eine Senkung des Spritverbrauchs erreicht wird.The hollow chamber plates 1, 4, 15 can also be designed as light metal and / or plastic elements, thereby reducing the fuel consumption.
Durch nicht m Fig. 2 dargestellte Klappen an den Ein- bzw. Ausströmöffnungen 2,3 der Stromungskanale 10 werden bestimmte Eigenschaften des Fahrzeugs 19, wie z.B. der Andruck des Fahrzeugs 19 auf dem Untergrund beeinflusst. Die an den Ausströmöffnungen 3, bzw. 3'' der Stromungskanale 10 angebrachte Klappen sowie die Form der Ausströmöffnungen 3 bzw. 3'' bewirken dabei Spoilereffekte.By flaps not shown in Fig. 2 at the inflow or outflow openings 2, 3 of the flow channels 10 certain properties of the vehicle 19, such as e.g. affects the pressure of the vehicle 19 on the ground. The flaps attached to the outflow openings 3 or 3 ″ of the flow channels 10 and the shape of the outflow openings 3 or 3 ″ cause spoiler effects.
