Abstract
Description
Die Erfindung betrifft ein Fahrzeug mit einer elektrochemischen Energiespeichereinheit, die in einem Mitteltunnel einer Fahrzeugkarosserie angeordnet ist.The invention relates to a vehicle with an electrochemical energy storage unit, which is arranged in a center tunnel of a vehicle body.
Aus der
Die
Der Erfindung liegt daher die Aufgabe zugrunde, das aus dem Stand der Technik bekannte Fahrzeug mit elektrochemischer Energiespeichereinheit in einer solchen Weise zu verbessern, dass die Energiespeichereinheit in besonders gewichtssparender Weise im Fahrzeug angeordnet werden kann und damit die Reichweite des Fahrzeugs optimiert werden kann.The invention is therefore based on the object to improve the known from the prior art vehicle with electrochemical energy storage unit in such a way that the energy storage unit can be arranged in a particularly weight-saving manner in the vehicle and thus the range of the vehicle can be optimized.
Die Aufgabe wird erfindungsgemäß mit einem Fahrzeug gelöst, welches die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved with a vehicle having the features specified in
Vorteilhafte Ausgestaltungen des erfindungsgemäßen Fahrzeugs sind Gegenstand der Unteransprüche.Advantageous embodiments of the vehicle according to the invention are the subject of the dependent claims.
Danach ist die elektrochemische Energiespeichereinheit in einem Mitteltunnel des Fahrzeugs angeordnet, welcher zumindest abschnittsweise aus einem faserverstärkten Kunststoff besteht. Insbesondere kann der Mitteltunnel in Gestalt eines Gehäuses ausgeführt sein, in dem die Energiespeichereinheit oder Teile der Energiespeichereinheit aufgenommen ist bzw. sind. Vorzugsweise besteht der Mitteltunnel aus einem kohlefaserverstärkten Kunststoff. Solche kohlefaserverstärkten Kunststoffe (karbonfaserverstärkte Kunststoffe oder CFK) haben eine geringe spezifische Dichte und Steifigkeit, haben somit ein hohes Leichtbau-Potential und gelten daher als vielversprechende innovative Werkstoffe für den Automobilbau. Die zur Verstärkung eingesetzten Kohlefasern haben ein geringes spezifisches Gewicht, sind hochfest und haben darüber hinaus schwingungsdämpfende Eigenschaften. CFK eignet sich somit hervorragend für die Verwendung in Strukturbauteilen in der Automobilindustrie.Thereafter, the electrochemical energy storage unit is arranged in a center tunnel of the vehicle, which at least partially consists of a fiber-reinforced plastic. In particular, the center tunnel can be designed in the form of a housing in which the energy storage unit or parts of the energy storage unit is or are received. Preferably, the center tunnel consists of a carbon fiber reinforced plastic. Such carbon fiber reinforced plastics (carbon fiber reinforced plastics or CFRP) have a low specific density and rigidity, thus have a high lightweight potential and are therefore considered promising innovative materials for the automotive industry. The carbon fibers used for reinforcement have a low specific weight, are high-strength and also have vibration-damping properties. CFRP is therefore ideally suited for use in structural components in the automotive industry.
Die erfindungsgemäße Gestaltung des Mitteltunnels als faserverstärktes Kunststoffteil, insbesondere als CFK-Bauteil, führt somit – verglichen mit herkömmlich zum Einsatz kommenden Tunnelstrukturen aus Aluminium – zu einer erheblichen Gewichtsersparnis des Fahrzeugs, was eine Erhöhung der Reichweite des Fahrzeugs mit sich bringt. in Aluminiumbauweise hergestellte Fahrzeugteile sind aufgrund der zu verwendenden Wandstärken bis zu 30% schwerer als vergleichbare CFK-Bauteile, so dass durch den Werkstoff CFK eine deutliche Gewichtsersparnis gegenüber Aluminium erreicht werden kann. Insbesondere sind Carbonfaserkomponenten bei gleicher Stabilität um bis zu 50% leichter als Stahlkomponenten. Die Verwendung faserverstärkter Kunststoffe zur Herstellung des Mitteltunnels bringt somit Bauraumgewinn für die Batteriemodule und spart gleichzeitig Fahrzeuggewicht.The design of the center tunnel according to the invention as a fiber-reinforced plastic part, in particular as a CFRP component, thus leads to a considerable weight saving of the vehicle compared to conventionally used tunnel structures made of aluminum, which entails an increase in the range of the vehicle. Due to the wall thicknesses to be used, vehicle parts produced in aluminum construction are up to 30% heavier than comparable CFRP components, so that a significant weight saving compared to aluminum can be achieved with the CFRP material. In particular, carbon fiber components with the same stability are up to 50% lighter than steel components. The use of fiber-reinforced plastics for the production of the center tunnel thus brings space savings for the battery modules and simultaneously saves vehicle weight.
Der als CFK-Leichtbaustruktur ausgestaltete Mitteltunnel kann unter Zuhilfenahme von FEM-Berechnungen in einer solchen Weise ausgelegt werden, dass Rahmensteifigkeiten und Crash-Sicherheit im Spitzenbereich gängiger Automobil-Standards bei gleichzeitiger markanter Absenkung des Systemgewichts erreicht werden. Die Realisierung der CFK-Leichtbaustruktur setzt somit einen neuen Referenzstandard bei der Kombination aus Funktion und Sicherheit: High-End Fertigungstechnik und moderne Carbon-Konzeptentwicklung ermöglichen die Realisierung technischer Rohbaufunktionen und genügen hohen Anforderungen in Bezug auf Biege- und Torsionssteifigkeit und geometrischer Gestaltungsvielfalt.The center tunnel designed as a CFRP lightweight structure can be designed with the help of FEM calculations in such a way that frame stiffness and crash safety in the top range of common automotive standards can be achieved while significantly reducing the system weight. The realization of the CFRP lightweight construction structure thus sets a new reference standard in the combination of function and safety: High-end production technology and modern carbon concept development enable the realization of technical shell construction functions and meet high requirements in terms of bending and torsional rigidity and geometric design diversity.
Im folgenden wird die Erfindung anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Dabei zeigen:In the following the invention will be explained in more detail with reference to an embodiment shown in the drawings. Showing:
