Abstract

One hollow profile at least is used for stiffening the vehicle substructure. The hollow profile section is a torsion tube running centrally at the vehicle substructure (1) in the manner of a cardan shaft tunnel. The hollow profile sections (3) are the side thresholds (18,19) of the road vehicle substructure. A carriage (15) for the reception of the batteries (4,5) is arranged in the hollow profile section (3) and can be withdrawn from it. The opposite lying rear driven wheels (8,9), are respectively driven by separate electric motors (10,11) and for rpm balance when travelling around bends is achieved by an electronic differential (12). ADVANTAGE - Gives optimum lowering of centre of gravity of vehicle. Batteries do not reduce passive safety in event of frontal collision. Gives as favourable as possible use of space.

Description

Die Erfindung betrifft ein von einem Elektromotor ange­ triebenes, einen Batterieraum mit Batterien aufweisendes Kraftfahrzeug mit einem Fahrzeugunterbau, welcher durch zumindest ein in Fahrzeuglängsrichtung verlaufendes Hohl­ profil ausgesteift ist.The invention relates to an electric motor driven, having a battery room with batteries Motor vehicle with a vehicle substructure, which by at least one hollow extending in the longitudinal direction of the vehicle profile is stiffened.

Kraftfahrzeuge mit Elektromotor haben gegenüber solchen mit Verbrennungskraftmotor den Vorteil, besonders umwelt­ freundlich zu sein. Problematisch ist bei ihnen jedoch die Unterbringung der zahlreichen und schweren Batterien im Batterieraum. Üblicherweise ordnet man die Batterien nebeneinander und übereinander entweder dort an, wo bei herkömmlichen Kraftfahrzeugen der Verbrennungsmotor sitzt, oder im sonst als Kofferraum bestimmten Fahrzeug­ teil. Hierdurch erhöht sich die Schwerpunktlage des Fahrzeugs, was sein Fahrverhalten ungünstig beeinflußt. Weiterhin muß das Kraftfahrzeug zusätzlich ausgesteift werden, um die Batterielast im vorderen oder hinteren Fahrzeugbereich aufnehmen zu können. Hierdurch wird das Kraftfahrzeug gegenüber herkömmlichen Kraftfahrzeugen schwerer, was zu seinem Betrieb zusätzliche Energie und deshalb mehr Batterien erfordert. Die Anordnung schwerer Batterien im Fahrzeugheck führt bei einem Frontalauf­ prall zu einer erhöhten Verformung des Kraftfahrzeugs, weil dann die kinetische Energie der Batterien durch Ver­ formung des Kraftfahrzeugs vernichtet werden muß.Motor vehicles with an electric motor have compared to such with internal combustion engines the advantage, especially environmental to be friendly. However, they are problematic housing the numerous and heavy batteries in the battery room. Usually you arrange the batteries side by side and on top of each other either where conventional motor vehicles the internal combustion engine sits, or in the vehicle otherwise designated as a trunk part. This increases the center of gravity of the Vehicle, which adversely affects its driving behavior. Furthermore, the motor vehicle must also be braced be to the battery load in the front or rear To be able to record vehicle area. This will Motor vehicle compared to conventional motor vehicles heavier, resulting in additional energy and operation therefore requires more batteries. The arrangement heavier Batteries in the rear of the vehicle cause a frontal run bounces to an increased deformation of the motor vehicle, because then the kinetic energy of the batteries by Ver Formation of the motor vehicle must be destroyed.

Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahr­ zeug der eingangs genannten Art so auszubilden, daß seine Batterien für das Fahrverhalten und die passive Sicherheit sowie die Raumausnutzung des Kraftfahrzeugs möglichst günstig untergebracht sind. The invention has for its object a motor vehicle to train the type mentioned in such a way that its batteries for driving behavior and passive Security and space utilization of the motor vehicle are accommodated as cheaply as possible.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Hohlprofil den Batterieraum bildet.This object is achieved in that the hollow profile forms the battery compartment.

Durch diese Gestaltung werden die Batterien in einem bis­ her für die Unterbringung von Teilen des Kraftfahrzeugs ungenutzten Kraftfahrzeugbereich angeordnet. Da für die Unterbringung der Batterien ein Hohlprofil des Fahrzeug­ unterbaus benutzt wird, sind die Batterien in geringer Höhe angeordnet, so daß der Schwerpunkt des Kraftfahr­ zeuges niedrig ist, was sich für das Fahrverhalten vor­ teilhaft auswirkt. Für die passive Sicherheit des Kraft­ fahrzeugs ist günstig, daß die schweren Batterien in einem in Fahrzeuglängsrichtung verlaufenden Hohlprofil vorgesehen sind, weil sie dadurch bei einem Frontalauf­ prall nach vorn aus dem Hohlprofil herausgelangen können, so daß sie zu keiner Verformung des Fahrgast­ raumes beitragen. Die Erfindung ermöglicht bei der Karos­ seriegestaltung eine wesentlich größere Freiheit als bei herkömmlichen Fahrzeugen; sie ist insbesondere auch bei Kabrioletts anwendbar, weil diese aus Gründen der Tor­ sionssteifigkeit ohnehin im Querschnitt relativ groß bemessene Hohlprofile im Fahrzeugunterbau benötigen, in welchem die Batterien problemlos untergebracht werden können.With this design, the batteries are in one to forth for the accommodation of parts of the motor vehicle arranged unused motor vehicle area. As for the Housing the batteries a hollow profile of the vehicle batteries is used, the batteries are lower Height arranged so that the center of gravity of the motor vehicle stuff is low, what is for driving behavior partially affects. For the passive safety of the force vehicle is favorable that the heavy batteries in a hollow profile running in the longitudinal direction of the vehicle are provided because they are a frontal run bounce out of the hollow profile can so that they do not deform the passenger contribute space. The invention enables checks series design a much greater freedom than with conventional vehicles; it is particularly also at Convertibles applicable because these are for gate reasons Sion stiffness relatively large in cross-section anyway need dimensioned hollow profiles in the vehicle substructure, in which the batteries are easily accommodated can.

Die Erfindung ist mit besonders geringem Aufwand zu ver­ wirklichen, wenn das Hohlprofil ein zentral nach Art eines Kardantunnels am Fahrzeugunterbau vorgesehenes Tor­ sionsrohr ist. Ein solches Torsionsrohr muß aus Gründen der Torsionssteifigkeit ohnehin einen relativ großen Querschnitt haben, so daß sich in ihm die erforderlichen Batterien ohne Schwierigkeiten unterbringen lassen. The invention is very easy to ver real, if the hollow profile is a centrally according to Art of a cardan tunnel on the vehicle substructure sion tube is. Such a torsion tube must for reasons torsional stiffness is a relatively large one anyway Have a cross-section so that the necessary ones can be found in it Have batteries stored without difficulty.  

Statt ein zentrales Torsionsrohr als Batterieraum zu ver­ wenden, kann man gemäß einer vorteilhaften Weiterbildung der Erfindung auch Seitenschweller des Fahrzeugunterbaus als Batterieräume benutzen. Hierbei ist natürlich Voraus­ setzung, daß diese Seitenschweller einen ausreichend großen Querschnitt erhalten, was jedoch aus Gründen der Torsionssteifigkeit des Kraftfahrzeugs ohnehin vorteil­ haft ist.Instead of ver a central torsion tube as a battery room turn, you can according to an advantageous training the invention also side skirts of the vehicle underbody use as battery rooms. Of course, this is ahead setting that these side skirts a sufficient received large cross-section, but for reasons of Torsional rigidity of the motor vehicle is advantageous anyway is imprisoned.

Der Einbau der Batterien und ihr Austausch gegen neue oder neu geladene Batterien ist besonders rasch und ein­ fach möglich, wenn im Hohlprofil zur Aufnahme der Batte­ rien ein aus dem Hohlprofil herausziehbarer Wagen ange­ ordnet ist.The installation of the batteries and their replacement with new ones or newly charged batteries is particularly quick and a possible if in the hollow profile to hold the battery a carriage that can be pulled out of the hollow section is arranged.

Das Hohlprofil braucht zum Einsetzen der Batterien auf seiner Mantelfläche keine seine Festigkeit verringernde Öffnung aufzuweisen, wenn gemäß einer vorteilhaften Wei­ terbildung der Erfindung das Hohlprofil zum Einschieben oder Herausziehen der Batterien an der Stirnseite oder dem Fahrzeugheck eine absperrbare Öffnung hat.The hollow profile is used to insert the batteries its lateral surface does not reduce its strength Show opening if according to an advantageous Wei terbildung the invention the hollow profile for insertion or pulling out the batteries on the front or the rear of the vehicle has a lockable opening.

Der üblicherweise bei einem Kraftfahrzeug erforderliche Platz für ein Differential kann eingespart werden, wenn gegenüberliegende, angetriebene Räder jeweils durch einen separaten Elektromotor angetrieben sind und zum Drehzahlausgleich bei Kurvenfahrt ein elektronisches Differential vorgesehen ist. Bei einem solchen Kraft­ fahrzeug kann der Boden des Kofferraumes besonders tief verlaufen, so daß sein Volumen groß wird oder aber der Schwerpunkt des Kraftfahrzeugs auch bei beladenem Kof­ ferraum optimal niedrig liegt. The one usually required in a motor vehicle Space for a differential can be saved if opposite, driven wheels each by are driven by a separate electric motor and Electronic speed compensation when cornering Differential is provided. With such a force vehicle the floor of the trunk can be particularly deep run so that its volume becomes large or the Center of gravity of the motor vehicle, even when the car is loaded space is optimally low.  

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung schematisch dargestellt und wird nachfolgend beschrieben.The invention permits numerous embodiments. To further clarification of their basic principle is one of which is shown schematically in the drawing and is described below.

Fig. 4 einen Querschnitt durch ein ein zentrales Torsionsrohr bildendes Hohlprofil des Kraft­ fahrzeugs. Fig. 4 shows a cross section through a central torsion tube forming the hollow profile of the motor vehicle.

Die Fig. 1 zeigt ein Kraftfahrzeug, welches im wesent­ lichen aus einem Fahrzeugunterbau 1 und einer Fahrzeug­ karosserie 2 gebildet ist. Der Fahrzeugunterbau 1 hat ein über seine gesamte Länge sich erstreckendes, als zentrales Torsionsrohr kardantunnelartig ausgebildetes Hohlprofil 3, in welchem hintereinander Batterien, zum Beispiel die Batterien 4, 5, angeordnet sind. Da das Hohlprofil 3 sich über die gesamte Länge des Kraftfahr­ zeugs erstreckt, können in ihm alle zum Antrieb des Kraftfahrzeugs erforderlichen Batterien 4, 5 angeordnet werden. Fig. 1 shows a motor vehicle, which is formed in wesent union from a vehicle chassis 1 and a vehicle body 2 . The vehicle substructure 1 has a hollow profile 3 , which extends over its entire length and is designed as a central torsion tube, in which batteries, for example batteries 4 , 5 , are arranged one behind the other. Since the hollow section 3 extends over the entire length of the vehicle, all the batteries 4 , 5 required for driving the motor vehicle can be arranged in it.

Die Fig. 2 zeigt, daß das Hohlprofil 3 an der vorderen Stirnseite des Kraftfahrzeugs eine von einem Karosserie­ teil 6 abgedeckte Öffnung 7 hat. Im Falle eines Frontal­ aufpralls des Kraftfahrzeugs vermögen die Batterien 4, 5 und alle übrigen Batterien das Karosserieteil 6 wegzu­ drücken und nach vorn aus dem Hohlprofil 3 herauszuge­ langen oder aber sich unmittelbar am den Frontalaufprall verursachenden Hindernis abzustützen, so daß die Batte­ rien nicht zu einer Verformung des Kraftfahrzeugs bei­ tragen. Fig. 2 shows that the hollow profile 3 at the front end of the motor vehicle has an opening 7 covered by a body part 6 . In the event of a head-on collision of the motor vehicle, the batteries 4 , 5 and all the other batteries are able to push the body part 6 away and pull out from the hollow section 3 for a long time, or are supported directly on the obstacle causing the frontal impact, so that the batteries do not become one Deformation of the motor vehicle to wear.

Die Fig. 2 läßt weiterhin erkennen, daß zum Antrieb von Hinterrädern 8, 9 des Kraftfahrzeugs insgesamt zwei Elek­ tromotoren 10, 11 vorgesehen sind, welche von den Batte­ rien 4, 5 mit elektrischer Energie versorgt werden und über ein elektronisches Differential 12 derart gesteuert sind, daß bei Kurvenfahrt das jeweils äußere Hinterrad 8 oder 9 mit höherer Drehzahl angetrieben wird als das kur­ veninnere. Fig. 2 also shows that a total of two elec tric motors 10 , 11 are provided for driving rear wheels 8 , 9 of the motor vehicle, which are supplied by the batteries 4 , 5 with electrical energy and are controlled via an electronic differential 12 in this way that when cornering, the outer rear wheel 8 or 9 is driven at a higher speed than the cur veninnere.

Die Fig. 3 verdeutlicht, daß im Hohlprofil 3 ein auf Rollen 13, 14 verfahrbarer Wagen 15 angeordnet sein kann, der die Batterien 4 trägt. Dadurch ist es möglich, zum Zwecke des Batteriewechsels den Wagen mit allen Batterien 4, 5 aus dem Hohlprofil 3 herauszuziehen und ihn mit neuen Batterien zu beschicken. Fig. 3 shows that in the hollow section 3 a movable on rollers 13 , 14 carriage 15 can be arranged, which carries the batteries 4 . This makes it possible for the purpose of changing the battery to pull the car with all the batteries 4 , 5 out of the hollow profile 3 and to load it with new batteries.

In Fig. 3 sind des weiteren zwei Seitenschweller 18, 19 dargestellt, die anstelle des zentralen Hohlprofils 3 oder zusätzlich zu ihm als Batterieraum genutzt werden können, indem sie einen zur Aufnahme von Batterien er­ forderlichen Querschnitt erhalten.In Fig. 3, two side skirts 18 , 19 are also shown, which can be used instead of the central hollow profile 3 or in addition to it as a battery room by receiving a cross-section required for receiving batteries.

Die Fig. 4 zeigt gegenüber Fig. 3 vergrößert das Hohl­ profil 3 mit dem Wagen 15, welcher die Batterien 4 trägt. Zu erkennen ist, daß die Rollen 13, 14 jeweils in einer Längsprofilierung 16, 17 des Hohlprofils 3 laufen, so daß der Wagen 15 leicht in das Hohlprofil 3 hineinge­ schoben oder aus ihm herausgeschoben werden kann. Wenn er die richtige Position im Hohlprofil 3 einnimmt, muß er natürlich auf nicht gezeigte Weise fixiert werden. Fig. 4 shows compared to Fig. 3 enlarged the hollow profile 3 with the carriage 15 which carries the batteries 4 . It can be seen that the rollers 13 , 14 each run in a longitudinal profile 16 , 17 of the hollow profile 3 , so that the carriage 15 can easily be pushed into the hollow profile 3 or pushed out of it. If he takes the correct position in the hollow profile 3 , it must of course be fixed in a manner not shown.
