Die Aufgabe der Erfindung besteht darin, eine crashenergieabsorbierende Anordnung in einem Kraftfahrzeug anzugeben, zur sicheren Aufnahme von im Crashfall auftretender kinetischer Energie einer Hybridbatterie bzw. galvanischen Zelle, bei möglichst geringem Gewicht und Zusatzaufwand.The The object of the invention is a crashenergieabsorbierende Specify arrangement in a motor vehicle, for safe recording of occurring in the event of a crash kinetic energy of a hybrid battery or galvanic cell, with the lowest possible weight and additional expenses.
Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1. Die Unteransprüche betreffen vorteilhafte Aus- und Weiterbildungen der Erfindung.The The object is solved by the features of claim 1. The dependent claims relate to advantageous training and further education the invention.
Erfindungsgemäß ist vorgesehen, dass die galvanische Zelle in Crashrichtung vor dem Fahrschemel positioniert ist und dass wenigstens ein Deformationselement zur Aufnahme von Crashenergie zwischen galvanischer Zelle und Fahrschemel vorgesehen ist, wobei galvanische Zelle, Deformationselement bzw. Deformationselemente und Fahrschemel derart konfiguriert und angeordnet sind, dass im Crashfall ein neuer, einer Verdrehung der galvanischen Zelle entgegenwirkender Lastpfad ausgebildet wird. Durch die Existenz von dem oder den Deformationselementen zwischen galvanischer Zelle und Fahrschemel wird im Crashfall bereits ein Anteil der auftretenden Crashenergie vor dem Auflaufen der galvanischen Zelle auf den Fahrschemel aufgenommen. Diese Energieaufnahme erfolgt dabei in definierter, d. h. vorhersagbarer Art und Weise. Insbesondere stellt die spezielle Konfiguration und Anordnung von galvanischer Zelle, Deformationselementen und Fahrschemel sicher, dass sich die galvanische Zelle im Crashfall nicht verdreht und in Crashrichtung liegende Bauteile, wie beispielsweise einen Kraftstofftank, beschädigt oder in den Passagierraum eindringt.According to the invention provided that the galvanic cell in Crashrichtung before the Subframe is positioned and that at least one deformation element for absorbing crash energy between galvanic cell and subframe is provided, wherein galvanic cell, deformation element or Deformation elements and subframes are configured and arranged in this way are that in the event of a crash, a new, a rotation of the galvanic Cell counteracting load path is formed. By existence of the deformation element (s) between the galvanic cell and subframe is in the event of a crash already a share of occurring Crash energy before running the galvanic cell on the subframe added. This energy absorption takes place in defined, d. H. predictable way. In particular, the special represents Configuration and arrangement of galvanic cell, deformation elements and subframe sure that the galvanic cell in the event of a crash not twisted and lying in Crashrichtung components, such as a fuel tank, damaged or enters the passenger compartment.
Anders ausgedrückt bewegt sich die träge Masse der galvanischen Zelle im Crashfall im Wesentlichen in Crashrichtung und läuft damit definiert auf den Fahrschemel auf, wo sie sicher abgebremst wird. Im Crashfall führt die galvanische Zelle also eine definierte lineare Bewegung entlang eines neu ausgebildeten Lastpfades durch. Eine derartige Anordnung erlaubt insbesondere den Einsatz einer galvanischen Zelle in einem herkömmlichen Fahrzeug mit minimalem Zusatzaufwand zur Darstellung eines Hybridfahrzeuges. Insbesondere können bestehende Träger- und Tankanordnungen übernommen werden, da erfindungsgemäß zu deren Schutz im Crashfall, zusätzlich zu bereits bestehenden Lastpfaden, ein neuer Lastpfad ausgebildet wird. Hierzu dient das oder die speziell konfigurierten und angeordneten Deformationselemente in ihrem Zusammenwirken mit galvanischer Zelle und Fahrschemel. Bedarfsweise sind gegenüber einem herkömmlichen Fahrzeug weitere geringe Zusatzaufwände nötig, beispielsweise eine lokale Verstärkung des Fahrschemels. Aufgrund der Variabilität bei Konfiguration und Anordnung von galvanischer Zelle und Deformationselementen bezüglich des herkömmlichen Fahrzeuges sind diese Zusatzaufwände jedoch sehr beschränkt.Different Expressed, the inert mass moves the galvanic Cell in the event of a crash essentially in Crashrichtung and running thus defined on the subframe, where it is braked safely. In the event of a crash, the galvanic cell thus carries a defined one linear movement along a newly formed load path through. Such an arrangement allows in particular the use of a galvanic cell in a conventional vehicle with minimal additional effort to display a hybrid vehicle. In particular, existing carrier and tank arrangements can be adopted be, since according to the invention for their protection in Crash case, in addition to existing load paths, a new load path is formed. This is the purpose or the special configured and arranged deformation elements in their interaction with galvanic cell and subframe. If necessary, are opposite a conventional vehicle further small additional effort necessary, for example a local reinforcement of the subframe. Due to the variability in configuration and arrangement of galvanic cell and deformation elements with respect to of the conventional vehicle, these additional expenses but very limited.
Zusammenfassend wird, ausgehend von einem herkömmlichen Fahrzeug, die Anordnung einer galvanischen Zelle im Lastpfad vor einem Fahrschemel möglich, wodurch im Hybridfahrzeug wertvoller Platz im Bereich des Passagierraumes gewonnen wird, bei dennoch sicherem Crashverhalten.In summary is, starting from a conventional vehicle, the arrangement a galvanic cell in the load path in front of a subframe possible, which gives the hybrid vehicle more valuable space in the area of the passenger compartment is won, yet safe crash behavior.
Der neu ausgebildete Lastpfad wird dadurch optimiert, dass die galvanische Zelle im Wesentlichen auf derselben Höhe wie der Fahrschemel vorgesehen wird. Dies bedeutet, das die Schwerpunkte von galvanischer Zelle und Fahrschemel auf einer in Crashrichtung ausgerichteten Linie angeordnet sind und/oder das die galvanische Zelle unter- und oberhalb gleich weit über den Fahrschemel hinausragt. Somit läuft die galvanische Zelle im Crashfall etwa mittig auf den Fahrschemel auf, was deren Verdrehung entgegenwirkt und relativ einfache Deformationselemente ermöglicht. Alternativ ist auch eine versetzte Anordnung (seitlich und/oder in der Höhe) von galvanischer Zelle und Fahrschemel möglich, bei entsprechend aufwendigerer unterschiedlicher Gestaltung des oder der Deformationselemente.The newly formed load path is optimized by providing the galvanic cell substantially at the same height as the subframe. This means that the focal points of galvanic cell and subframe on a in Crashrichtung aligned line are arranged and / or protrudes the galvanic cell below and above the same distance above the subframe. Thus, the galvanic cell runs in the event of a crash approximately in the middle of the subframe, which counteracts their rotation and allows relatively simple deformation elements. Alternatively, a staggered arrangement (laterally and / or in height) of galvanic cell and subframe is possible, with correspondingly more complex different design of the deformation or the elements.
Ein vereinfachter Zusammenbau ergibt sich, indem die Deformationselemente am Fahrschemel befestigt, beispielsweise angeschraubt oder angegossen, werden. Zusätzlich kann ein Spalt zwischen galvanischer Zelle und Deformationselement vorgesehen sein, um eine ungestörte Bewegung des elastisch gelagerten Fahrschemels zu ermöglichen. Alternativ sind die Deformationselemente an der galvanischen Zelle vorgesehen.One simplified assembly results by the deformation elements attached to the subframe, for example screwed on or cast on, become. In addition, a gap between galvanic Cell and deformation element be provided to an undisturbed To allow movement of the elastically mounted subframe. Alternatively, the deformation elements on the galvanic cell intended.
Eine bewährte Methode der Bereitstellung der Deformationselemente ist deren Fertigung als Aluminium-Strangpressprofile. Diese haben eine hohe Energieaufnahmefähigkeit und Stabilität und sind damit besonders geeignet die kinetische Energie im Crashfall aufzunehmen und in Verformung umzuwandeln bzw. weiterzuleiten.A proven method of providing the deformation elements is their production as aluminum extruded profiles. These have a high energy absorption capacity and stability and are therefore particularly suitable kinetic energy in the event of a crash absorb and transform into deformation.
Mit besonders geringem Aufwand wird einer Verdrehung der galvanischen Zelle dadurch entgegengewirkt, das zwei Deformationselemente vorgesehen sind, die – in Querrichtung gesehen, also quer zur Crashrichtung – jeweils seitlich in den Endbereichen der galvanischen Zelle angeordnet sind. Damit wird eine definierte lineare Bewegung der galvanischen Zelle im Crashfall bei minimalem Gewichts- und Materialaufwand sichergestellt.With especially little effort is a rotation of the galvanic Cell counteracted by the two deformation elements provided are, which - seen in the transverse direction, ie across the Crashrichtung - each are arranged laterally in the end regions of the galvanic cell. This is a defined linear movement of the galvanic cell ensured in the event of a crash with minimal weight and material costs.
Eine noch bessere Absorbtion der im Crashfall auftretenden Energie wird dadurch erreicht, dass zusätzliche Deformationselemente in Crashrichtung gesehen vor der galvanischen Zelle angeordnet werden.A Even better absorption of the energy occurring in the event of a crash is achieved by additional deformation elements as seen in the direction of the crash in front of the galvanic cell.
Noch weiter können die Crasheigenschaften verbessert werden, wenn die galvanische Zelle als Hochvoltbatterie mit einem sie umgebenden Schutzgehäuse ausgeführt ist, das ebenfalls zur Energieabsorption nutzbar ist.Yet further, the crash properties can be improved if the galvanic cell as a high-voltage battery with a surrounding Protective housing is executed, which is also for Energy absorption is available.
In einer bevorzugten Ausführungsform der Erfindung ist die galvanische Zelle im Heckbereich eines Kraftfahrzeuges, in Fahrtrichtung gesehen hinter dem hinteren Fahrschemel, angeordnet. Die Anbringung der galvanischen Zelle im Bereich des Kofferraums, insbesondere in der Reserveradmulde, ermöglicht deren Unterbringung bei minimalen Bauraumverlusten. Durch die erfindungsgemäße, crashenergieabsorbierende Anordnung ist im Falle eines Heckcrashs eine sichere Aufnahme und Weiterleitung von auftretender kinetischer Energie an den hinteren Fahrschemel gewährleistet.In a preferred embodiment of the invention is the Galvanic cell in the rear of a motor vehicle, in the direction of travel seen behind the rear subframe, arranged. The attachment the galvanic cell in the trunk area, in particular in the spare wheel well, allows their accommodation with minimal installation space losses. By the invention, Crashenergieabsorbierende arrangement is in the event of a rear crash a safe recording and transmission of occurring kinetic Ensures energy to the rear subframe.
In einer anderen, bevorzugten Ausführungsform der Erfindung ist die galvanische Zelle im Frontbereich des Kraftfahrzeuges, in Fahrtrichtung gesehen vor dem vorderen Fahrschemel, angeordnet. Damit können neue Bauräume erschlossen werden, wobei im Falle eines Frontalcrashs eine sichere Aufnahme und Weiterleitung von auftretender kinetischer Energie an den vorderen Fahrschemel gewährleistet ist.In another, preferred embodiment of the invention is the galvanic cell in the front area of the motor vehicle, in Direction seen in front of the front subframe, arranged. This new space can be developed, in case of a frontal crash, a secure recording and forwarding of occurring kinetic energy to the front subframe is guaranteed.
