Description

Frontendbereich frontend area
Die Erfindung betrifft einen Frontendbereich eines Kraftfahrzeugs, insbesondere eines Personenkraftwagens, gemäß dem Oberbegriff des Anspruch 1.The invention relates to a front end area of a motor vehicle, in particular a passenger car, according to the preamble of claim 1.
Aus der DE 35 42 376 AI ist ein Kraftfahrzeug mit einem benachbart einer Fahrbahn verlaufenden Bugendteil bekannt . Hierbei sind die zur Kühlung der Bremsen dienenden Luftleit- kanäle einstückig mit dem Bugendteil ausgebildet, wobei jeder Luftleitkanal zumindest über einen Teilbereich seiner Längserstreckung durch eine zur Fahrbahn hin offene Rinne des Bugendteils dargestellt ist. Durch diese Anordnung wird eine im Aufbau und in der Montage einfache Vorrichtung zur Kühlung der Bremsen geschaffen. Zusätzlich wird durch die Anordnung der Luftleitkanäle in einem eine Unterbodenverkleidung bildenden Abschnitt des Bugendteils der Luftwiderstandsbeiwert des Fahrzeugs reduziert .From DE 35 42 376 AI a motor vehicle with a bent part running adjacent to a roadway is known. In this case, the air guiding channels used to cool the brakes are formed in one piece with the bending part, each air guiding channel being represented at least over part of its longitudinal extent by a groove of the bending part which is open towards the roadway. This arrangement creates a device for cooling the brakes that is simple in construction and assembly. In addition, the arrangement of the air guiding channels in a section of the bent part that forms an underbody paneling reduces the drag coefficient of the vehicle.
Aus der DE 42 08 999 C2 ist ein aerodynamisches und verstellbares Unterbodenfrontende für ein Kraftfahrzeug bekannt. Dieses besteht aus einer formfesten Bugwanne, die mit Hilfe eines Verstellmechanismus schottartig aus einer Grundposition in wenigstens eine tiefer liegende und in Fahrtrichtung vorverlagerte Wirkposition absenkbar ist, wobei vertikale Schottwände der Bugwanne in jeder Wannenposition unter vertikale Abschnitte der Karosserie greifen und einen geschlossenen Übergang mit der Karosserie bilden. Der Boden der Wanne erstreckt sich im wesentlichen über die gesamte Unterboden- Öffnung des Motorraums, wobei an den Radkästen angepasste vertikale Schottwände vorgesehen sind. Die Front der Bugwanne ist über einen Bereich zwischen den Vorderrädern als Bugschürze ausgebildet, welche in abgesenkter Wirkposition mit einer Fahrbahn einen Venturi-Querschnitt bildet, wobei die Bugwanne und eine im Boden oder in der Bugwanne unterhalb deren Grundposition angeordnete Anlenkachse verschwenkbar ausgebildet ist.An aerodynamic and adjustable underbody front end for a motor vehicle is known from DE 42 08 999 C2. This consists of a rigid bow pan, which can be lowered with the help of an adjustment mechanism into a bulkhead position from at least one lower position and forward in the direction of travel, vertical bulkhead walls of the bow pan reaching under vertical sections of the body in each pan position and a closed transition with the body form. The bottom of the tub extends essentially over the entire underbody Opening of the engine compartment, with vertical bulkheads adapted to the wheel arches. The front of the front hull is formed over a region between the front wheels as a front apron, which forms a Venturi cross-section in the lowered operative position with a roadway, the front hull and a pivot axis arranged in the floor or in the front trough below its basic position being designed to be pivotable.
Aus der DE 36 13 303 Cl ist eine absenkbare Unterbodenverkleidung für das Frontende von Kraftfahrzeugen bekannt. Diese wird durch eine eigensteife, elastisch verformbare Platte gebildet und ist mittels eines Verstellmechanismus gegen eine Fahrbahn durchbiegbar. Durch die elastische Verformungsmöglichkeit der Unterbodenverkleidung unter Beibehaltung des flächig geschlossenen Übergangs zu den frontseitigen Karosserieteilen kann die Stellung der Unterbodenverkleidung den gegebenen Fahrbedingungen angepasst werden, ohne dass zusätzlich ungewollte Luftströmungseinflüsse entstehen, die durch neue Regelvorgänge wieder ausgeglichen werden müssen.DE 36 13 303 Cl a lowerable underbody paneling for the front end of motor vehicles is known. This is formed by an inherently rigid, elastically deformable plate and can be deflected against a roadway by means of an adjustment mechanism. Due to the possibility of elastic deformation of the underbody cladding while maintaining the flat transition to the front body parts, the position of the underbody cladding can be adapted to the given driving conditions without additional unwanted air flow influences that have to be compensated for by new control processes.
Aus der DE-PS 1 286 917 ist eine Abdeckung einer Unterseite eines Personenkraftwagens bekannt . Diese besteht aus einer unter dem Fahrgestellrahmen und dem Wagenboden angeordneten flachen Wanne, die Ausschnitte für die Räder und hochgezogene Ränder aufweist . Dabei stehen die Ränder der Wanne über die Ränder des Wagenaufbaus vor. Diese vorstehenden Wannenränder ersetzen an der vorderen und hinteren Stirnseite des Kraftfahrzeugs die sonst dort vorhandenen Stoßstangen und bilden an den Längsseiten des Fahrzeugs, wo sie über den unteren Rand der Türen vorstehen, einen Stoßschutz. Um den an den Fahrzeugstirnseiten regelmäßig höheren Stoßbeanspruchungen Rechnung zu tragen, ist der Rand der Wanne am vorderen und hinteren Ende breiter als an den Längsseiten.From DE-PS 1 286 917 a cover of an underside of a passenger car is known. This consists of a flat trough arranged under the chassis frame and the vehicle floor, which has cutouts for the wheels and raised edges. The edges of the tub protrude beyond the edges of the car body. These protruding trough edges replace the bumpers that are otherwise present on the front and rear end faces of the motor vehicle and form a bumper on the long sides of the vehicle, where they protrude beyond the lower edge of the doors. In order to take into account the higher impact stresses regularly on the front of the vehicle, the edge of the trough is wider at the front and rear than at the long sides.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Frontendbereich eines Kraftfahrzeugs eine verbes- serte Ausführungsform anzugeben, bei der insbesondere die Unfallfolgen für einen Fußgänger reduziert werden sollen.The present invention is concerned with the problem of improving a front end area of a motor vehicle. Serte embodiment to specify, in particular the consequences of an accident for a pedestrian to be reduced.
Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst, vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche .This object is achieved by the subject matter of the independent claim, advantageous developments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem Frontendbereich eines Kraftfahrzeugs, anstelle des parallel und unterhalb des bekannten Stoßfängerquerträgers angeordneten zusätzlichen Querträgers, eine untere Motorraumverkleidung als steifes Formteil auszubilden und in ihrem vorderen Bereich bis unter und hinter ein vorderes Ende der Stoßfängeranordnung zu verlängern. Das Formteil erstreckt sich im wesentlichen über die gesamte Fahrzeugbreite und bietet dadurch den Vorteil einer prinzipiell über die gesamte Fahrzeugbreite gleichen Steifigkeit . Bei einer Kollision mit einem Fußgänger ist durch das derart ausgebildete Formteil eine wirkungsvolle Abstützung des Unterschenkels des Fußgängers gegeben, wodurch ein Eindringen unterhalb des Stoßfängers und damit ein großer Kniebeugewinkel vermieden werden können. Zudem bewirkt die verlängerte Motorraumverkleidung, dass der Fußgänger im Crashfall auf der leicht deformierbaren Motorhaube auftrifft und nicht vom Fahrzeug überrollt wird. Mit der erfindungsgemäßen Lösung lassen sich einerseits die in Zukunft geltenden hohen gesetzlichen Anforderungen an den Fußgängerschutz leichter erfüllen, andererseits vermindert sich das Risiko von Unfallfolgen, für Fußgänger. Darüber hinaus ist das Formteil wesentlich kostengünstiger und leichter herzustellen als ein zusätzlicher unterer Querträger.The invention is based on the general idea that, in a front end area of a motor vehicle, instead of the additional cross member arranged parallel and below the known bumper cross member, a lower engine compartment trim is designed as a rigid molded part and is extended in its front area to under and behind a front end of the bumper arrangement. The molded part extends essentially over the entire width of the vehicle and thereby offers the advantage of a rigidity which is basically the same over the entire width of the vehicle. In the event of a collision with a pedestrian, the molded part designed in this way provides effective support for the lower leg of the pedestrian, as a result of which penetration below the bumper and thus a large knee bending angle can be avoided. In addition, the extended engine compartment trim means that the pedestrian hits the easily deformable bonnet in the event of a crash and is not overrun by the vehicle. On the one hand, the solution according to the invention makes it easier to meet the high statutory requirements for pedestrian protection that will apply in the future, and on the other hand reduces the risk of accidents for pedestrians. In addition, the molded part is much cheaper and easier to manufacture than an additional lower cross member.
Gemäß einer besonders bevorzugten Ausführungsform kann vorgesehen sein, zumindest den vorderen Bereich der Motorraumverkleidung aus Kunststoff auszubilden und/oder zumindest im vorderen Bereich der Motorraumverkleidung aussteifende Strukturelemente zu integrieren. Kunststoffe gelten aufgrund ihrer Materialeigenschaften und ihrer Formgebungsmδglichkeiten als besonders geeignet für den Automobilbau. Durch die Ausbildung des Formteils aus Kunststoff und die Integration von aussteifenden Strukturelementen kann zum einen Gewicht gespart werden und zum anderen ist es möglich, die Kosten für die Herstellung des Formteils im Vergleich zu den Kosten eines bekannten Querträgers deutlich zu reduzieren. Durch die aussteifenden Strukturelemente kann zusätzlich die Steifigkeit des Formteils individuell beeinflusst werden.According to a particularly preferred embodiment, provision can be made to form at least the front area of the engine compartment lining from plastic and / or to integrate structural elements stiffening at least in the front area of the engine compartment lining. Due to their material properties and their shaping possibilities, plastics are considered to be particularly suitable for the automotive industry. By forming the molded part from plastic and integrating stiffening structural elements, weight can be saved on the one hand and on the other hand it is possible to significantly reduce the costs for the production of the molded part compared to the costs of a known cross member. The stiffness of the molded part can also be individually influenced by the stiffening structural elements.
Eine besonders günstige Ausführungsform der erfindungsgemäßen Lösung ist dadurch gekennzeichnet, dass der vordere Bereich der Motorraumverkleidung eine höhere Steifigkeit aufweist als die Stoßfängeranordnung und/oder dass zumindest der vordere Bereich der Motorraumverkleidung eine gleichmäßige Steifigkeit über die Fahrzeugbreite aufweist. Die leicht zu deformierende Stoßfängeranordnung dämpft den ersten Aufprall und damit die Unfallfolgen für den Fußgänger, wogegen die höhere Steifigkeit im vorderen Bereich der Motorraumverkleidung gewährleistet, dass der Unterschenkel des Fußgängers abgestützt wird und damit ein zu großer Kniebeugewinkel und/oder das Eindringen des Unterschenkels in einen Raum unterhalb des Stoßfängers vermieden wird. Im Crash-Fall wird dadurch der Fußgänger auf die relativ weiche und leicht zu deformierende Motorhaube geschleudert und nicht vom Fahrzeug überrollt, was zur Folge hat, dass ein mögliches Verletzungsrisiko des Fußgängers deutlich reduziert wird.A particularly favorable embodiment of the solution according to the invention is characterized in that the front region of the engine compartment lining has a higher rigidity than the bumper arrangement and / or that at least the front region of the engine compartment lining has a uniform rigidity over the vehicle width. The easily deformable bumper arrangement dampens the first impact and thus the consequences of an accident for the pedestrian, whereas the higher rigidity in the front area of the engine compartment trim ensures that the pedestrian's lower leg is supported and thus an excessive knee bending angle and / or the penetration of the lower leg into one Space below the bumper is avoided. In the event of a crash, the pedestrian is thrown onto the relatively soft and easily deformable bonnet and is not overrun by the vehicle, which has the consequence that a possible risk of injury to the pedestrian is significantly reduced.
Eine vorteilhafte Weiterbildung der Erfindung ist gekennzeichnet durch ein am vorderen Ende des Formteils angeordnetes Verkleidungselement . Das Verkleidungselement kann dabei rein designerischen Zwecken dienen und/oder gemäß einer weiteren Ausführungsform energieabsorbierend ausgebildet sein. Hierdurch ist es einerseits möglich, den vorderen unteren Endbereich des Fahrzeugs individuell zu verkleiden und damit den optischen Gesamteindruck des Frontbereichs des Fahrzeugs zu beeinflussen, andererseits gewährleistet die energieabsorbierende Ausbildung eine aufpralldämpfende Wirkung. Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus den zugehörigen Figurenbeschreibungen anhand der Zeichnungen.An advantageous development of the invention is characterized by a cladding element arranged at the front end of the molded part. The cladding element can serve purely design purposes and / or, according to a further embodiment, be designed to absorb energy. This makes it possible, on the one hand, to individually dress the front lower end region of the vehicle and thus influence the overall visual impression of the front region of the vehicle, and on the other hand, the energy-absorbing design ensures an impact-absorbing effect. 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 Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination indicated in each case, but also in other combinations or on their own without departing from the scope of the present invention.

Unabhängig von der Richtung einer einwirkenden Kraft 2, 1 " oder 2", weist die Motorraumverkleidung 1 demnach einen zumindest ähnlich großen Deformationswiderstand auf.1, the depressions 10, the beads 9 and the bulges 15 are arranged in such a way that, at least in the front region 14 of the engine compartment trim 1 along the edge 19, a uniform stiffness is achieved across the vehicle width. Regardless of the direction of an applied force 2, 1 "or 2", the engine compartment trim 1 accordingly has an at least similarly large deformation resistance.
Gemäß Fig. 2 ist die Motorraumverkleidung 1 in ihrem vorderen Bereich 14 bis unter und hinter ein vorderes Ende einer Stoßfängeranordnung 3 bzw. eines Verkleidungselements 8 verlängert . Um die Funktion der verlängerten Motorraumverkleidung 1 zu gewährleisten, ist vorgesehen, dass die Stoßfängeranordnung 3 bzw. das Verkleidungselement 8 eine geringere Steifigkeit aufweisen als zumindest der vordere Bereich 14 des Formteils 1. Das Verkleidungselement 8 kann dabei als Bestandteil der Stoßfängeranordnung 3 ausgebildet sein und energieabsorbierende Eigenschaften aufweisen. Gemäß Fig. 2 ist die Motorraumverkleidung 1 an ihrem in Fahrtrichtung gesehen hinteren Bereich 17 über ein Halterungselement 11 an einem Integralträger 6 angebracht, welcher Bestandteil einer nicht dargestellten Karosserie ist. Zusätzlich zu den Vertiefungen 10 bzw. den Aufwölbungen 15 können an der Motorraumverkleidung 1 aussteifende Strukturelemente 7 angeordnet sein. Im vorderen Bereich 14 des Formteils 1, also entlang des vorderen Randes 19 ist dieser als Rastnase 4 ausgebildet und greift in eine dazu korrespondierende Aufnahme 18 ein, welche am Verkleidungselement 8 angeordnet ist. Hierdurch kann ein strömungsgünstiger und geschlossener Übergang zwischen dem Verkleidungselement 8 und dem Formteil 1 hergestellt werden. Wie vorstehend erwähnt ist es prinzipiell auch denkbar, das Verkleidungselement 8 als integralen Bestandteil der Stoßfängeranordnung 3 auszubilden.2, the engine compartment trim 1 is extended in its front region 14 to below and behind a front end of a bumper arrangement 3 or a trim element 8. In order to ensure the function of the extended engine compartment trim 1, it is provided that the bumper arrangement 3 or the cladding element 8 have a lower rigidity than at least the front area 14 of the molded part 1. The cladding element 8 can be designed as part of the bumper arrangement 3 and absorbs energy Have properties. 2, the engine compartment trim 1 is attached to its rear region 17, viewed in the direction of travel, via a mounting element 11 on an integral support 6, which is part of a body, not shown. In addition to the depressions 10 or the bulges 15, structural elements 7 stiffening can be arranged on the engine compartment lining 1. In the front area 14 of the molded part 1, that is to say along the front edge 19, the latter is designed as a detent 4 and engages in a corresponding receptacle 18 which is arranged on the trim element 8. As a result, a streamlined and closed transition can be produced between the covering element 8 and the molded part 1. As mentioned above, it is also conceivable in principle to design the trim element 8 as an integral part of the bumper arrangement 3.
Des weiteren ist die Motorraumverkleidung 1 hinter und unter der Stoßfängeranordnung 3 derart angeordnet, dass ein vertikaler Abstand V zwischen der Stoßfängeranordnung 3 und der Motorraumverkleidung 1 größer ist als ein horizontaler Abstand H zwischen den jeweiligen vorderen Endbereichen der Stoßfängeranordnung 3 und des Formteils 1 (vgl. Fig. 2) . Um die Aufgabe des Fußgängerschutzes wirkungsvoll erfüllen zu können, weist eine frontseitig an das vordere Ende der Stoßfängeranordnung 3 und des Formteils 1 angelegte Tangente T, welche in einer vertikalen und parallel zur Fahrzeuglängsrichtung angeordneten Ebene verläuft, einen Neigungswinkel α von weniger als 15 Grad gegenüber der Vertikalen auf. Hierdurch wird die gewünschte Abstützung des Unterschenkels des Fußgängers bei einem Aufprall erreicht und ein Eindringen unterhalb der Stoßfängeranordnung 3 vermieden.Furthermore, the engine compartment trim 1 is arranged behind and under the bumper arrangement 3 such that a vertical distance V between the bumper arrangement 3 and the engine compartment trim 1 is greater than a horizontal distance H between the respective front end regions of the bumper arrangement 3 and the molded part 1 (cf. Fig. 2). In order to be able to perform the task of pedestrian protection effectively, a tangent T applied to the front of the front end of the bumper arrangement 3 and the molded part 1, which runs in a vertical plane parallel to the longitudinal direction of the vehicle, has an inclination angle α of less than 15 degrees with respect to that Vertical on. In this way, the desired support of the lower leg of the pedestrian is achieved in the event of an impact and penetration below the bumper arrangement 3 is avoided.
Zusammenfassend lassen sich die wesentlichen Merkmale der Erfindung wie folgt charakterisieren: An einem Frontendbereich 12 eines Kraftfahrzeugs ist eine untere Motorraumverkleidung 1 als steifes Formteil ausgebildet und in ihrem vorderen Bereich 14 bis unter und hinter ein vorderes Ende der Stoßfängeranordnung 3 verlängert, wodurch eine wirkungsvolle Abstützung des Unterschenkels eines Fußgängers, welcher mit dem Fahrzeug kollidiert, gegeben ist und wodurch ein Eindringen unterhalb der Stoßfängeranordnung 3 sowie ein zu großer Kniebeugewinkel vermieden werden.In summary, the essential features of the invention can be characterized as follows: At a front end region 12 of a motor vehicle, a lower engine compartment trim 1 is designed as a rigid molded part and is extended in its front region 14 to below and behind a front end of the bumper arrangement 3, thereby providing effective support for the lower leg of a pedestrian who collides with the vehicle and thereby penetration below the bumper assembly 3 and an excessive knee bending angle are avoided.
Hierdurch lassen sich die in Zukunft geltenden hohen gesetzlichen Anforderungen an den Fußgängerschütz leichter erfüllen und es vermindert sich das Risiko von Unfallfolgen für Fußgänger. Darüber hinaus ist das Formteil 1 wesentlich kostengünstiger und leichter herzustellen als beispielsweise ein zusätzlicher Querträger. This makes it easier to meet the high legal requirements for pedestrian protection that will apply in the future and reduces the risk of accidents for pedestrians. In addition, the molded part 1 is much cheaper and easier to manufacture than, for example, an additional cross member.
