Abstract

In order to supply the on-board network, the electrical power supply system has an electrical generator (6) which can be driven by an internal combustion engine (7). The generator (6) is driven by an internal combustion engine (7) which is independent of the traction engine of the motor vehicle and supplies sufficient energy to the on-board network whenever the vehicle battery power supply is no longer adequate because of a large number of electrical loads. The generator (6) and the independent internal combustion engine (7) are arranged in the rear end of the motor vehicle, to be precise in the spare-wheel recess (3). This results in a favourable axle-load distribution, since the weight of the generator is taken away from the front axle and the rear axle is essentially loaded by both the weight of the generator (6) and the weight of a small, independent internal combustion engine (7). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Stromversorgungs­ anlage für Kraftfahrzeuge, insbesondere für Personen­ kraftwagen, mit einer Batterie sowie einem durch eine Brennkraftmaschine antreibbaren elektrischen Generator, die das Bordnetz versorgen.The invention relates to a power supply Plant for motor vehicles, in particular for people motor vehicle, with a battery and one by one Internal combustion engine driven electric generator, that supply the electrical system.

An das Bordnetz eines Kraftfahrzeuges werden immer mehr elektrische Verbraucher angeschlossen, die zum Teil auch gleichzeitig arbeiten. Es kann sich um Stellmotore für Teile des Sitzes, für Schlösser, Klappen u. ä. handeln, aber auch um elektrisch heizbare Scheiben oder auch um Gebläse, die bei stehendem Fahrzeug betrieben werden sollen. Mit der Fülle der elektrischen Verbraucher, die aufgrund der immer mehr steigenden Komfortansprüche der Fahrzeugbenutzer noch zunehmen werden, ist der vom Fahrmotor des Fahrzeugs angetriebene Generator nicht mehr in der Lage, eine ausreichende Ladebilanz des Bordnetzes zu gewährleisten. Die Problematik nimmt noch zu, wenn das Kraftfahrzeug, wie häufig bei stark motori­ sierten Fahrzeugen, über weite Strecken mit niederer Drehzahl und ggf. auch nur über kürzere Strecken be­ trieben und wenn u. U. auch noch mehrere Stromverbraucher vorhanden sind, die auch bei stehendem Fahrzeug arbeiten.The electrical system of a motor vehicle is becoming more and more electrical consumers connected, some of them too work at the same time. It can be servomotors for Parts of the seat, for locks, flaps and. act. but also around electrically heated panes or around Blowers that are operated when the vehicle is stationary should. With the abundance of electrical consumers who due to the ever increasing demand for comfort Vehicle users will continue to increase, is from Driving motor of the vehicle driven generator is not more able to have a sufficient charge balance of the Ensure electrical system. The problem continues to when the motor vehicle, as is often the case with strong motori vehicles, over long distances with low Speed and possibly only over short distances driven and if u. U. also several electricity consumers are present, even when the vehicle is stationary work.

Ein entsprechendes Vergrößern der vom Fahrmotor direkt angetriebenen Lichtmaschine ist insbesondere aus Platz­ gründen nicht ohne weiteres möglich. Dies würde darüber hinaus auch noch den Achslastanteil der Vorderachse in unzuträglicher Weise erhöhen.A corresponding increase in the size of the drive motor directly driven alternator is particularly out of space start up not possible. This would be about  also the axle load share of the front axle in unreasonably increase.

Der Erfindung liegt die Aufgabe zugrunde, eine Stromver­ sorgungsanlage für Kraftfahrzeuge zu schaffen, mit der die sich aus einer unbefriedigenden Ladebilanz ergeben­ den Probleme beherrschbar sind, wobei auch die Achs­ lasten anteilsmäßig mehr auf die Hinterachse verlagert werden sollen.The invention has for its object a Stromver to create care system for motor vehicles with the which result from an unsatisfactory load balance the problems are manageable, including the axis loads shifted proportionally more to the rear axle should be.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der elektrische Generator durch eine vom Fahrmotor des Kraftfahrzeugs unabhängige Brennkraftmaschine ange­ trieben ist. Dabei ist es besonders zweckmäßig, diese Brennkraftmaschine im Heck des Kraftfahrzeuges anzu­ ordnen. Sie kann vorzugsweise im Bereich der Reserverad­ mulde eines Personenkraftwagens angeordnet werden.This object is achieved in that the electric generator by one of the traction motor of the Motor vehicle independent internal combustion engine is driven. It is particularly useful here Internal combustion engine in the rear of the motor vehicle organize. You can preferably in the area of the spare wheel trough of a passenger car can be arranged.

Dank dieser Maßnahmen ist es nicht mehr nötig, wie bisher, aufgrund der Vielzahl der elektrischen Ver­ braucher eine zweite Fahrzeugbatterie im Fahrzeug unterzubringen mit all den Kosten und Gewichtser­ höhungen. Es ist auch schon erwogen worden, zur Lösung der Probleme eine dritte Batterie einzubauen.Thanks to these measures, it is no longer necessary how so far, due to the variety of electrical Ver need a second vehicle battery in the vehicle to accommodate with all the costs and weight increases. It has also been considered to solve the problems of installing a third battery.

Die dem elektrischen Generator zugeordnete Brennkraft­ maschine wird mit dem gleichen Betriebsstoff, in der Regel Benzin, versorgt wie der eigentliche Antriebsmotor des Kraftfahrzeugs. Es sind daher keine eigenen Vorrats­ behälter erforderlich. Durch die Anordnung der unab­ hängigen Brennkraftmaschine für den Generator im Heck des Fahrzeugs, wo sich bei fast allen Personenkraftwagen auch der Brennstoffbehälter befindet, ist nur ein sehr geringer Aufwand für die Verlegung der Brennstofflei­ tungen erforderlich. Die nur für den Betrieb des elek­ trischen Generators ausgelegte Brennkraftmaschine kann stets mit einer optimalen Drehzahl betrieben werden, so daß die Leistungsausbeute sehr hoch und auch die Schad­ stoffbelastung sehr gering gehalten werden können. Auch Schalldämmungs- und Dämpfungsmaßnahmen sind gut be­ herrschbar, wenn nur ein kleiner Drehzahlbereich opti­ miert werden muß, was in gleicher Weise für den Generator gilt.The internal combustion engine assigned to the electric generator machine is operated with the same operating fluid in the Usually gasoline, supplied like the actual drive motor of the motor vehicle. It is therefore not a separate stock container required. By arranging the unab dependent internal combustion engine for the generator in the rear of the vehicle, where almost all passenger cars even the fuel tank is only a very little effort for relocating the fuel line necessary. The only for the operation of the elek tric generator designed internal combustion engine  always be operated at an optimal speed, so that the power yield is very high and the damage can be kept very low. Also Soundproofing and damping measures are good prevailable if only a small speed range opti must be lubricated, which in the same way for the Generator applies.

Die nach wie vor erforderliche Batterie des Fahrzeuges kann natürlich ebenfalls für die Versorgung des Bord­ netzes herangezogen werden, jedoch wird zumindest der größere Energieanteil bei der erfindungsgemäßen Lösung von dem durch die unabhängige Brennkraftmaschine ange­ triebenen Generator geliefert.The vehicle's battery, which is still required can of course also for the supply of the board network, but at least the greater energy share in the solution according to the invention of which by the independent internal combustion engine powered generator supplied.

Die Batterie des Fahrzeuges wird ab einem bestimmten Entleerungsgrad vom Bordnetz abgeschaltet. Der Ent­ leerungsgrad ist durch den Leistungsbedarf festgelegt, der erforderlich ist, um zumindest die kleine zusätz­ liche Brennkraftmaschine in Betrieb zu setzen, die den Generator antreibt. Die für den Generator vorgesehene eigene Brennkraftmaschine ist auf die notwendige Leistungsabgabe ausgelegt.The battery of the vehicle is determined from a certain one Degree of emptying switched off from the vehicle electrical system. The Ent degree of emptying is determined by the power requirement, which is required to at least add the little one to put into operation the internal combustion engine Generator drives. The one intended for the generator own internal combustion engine is on the necessary Power output designed.

Die unabhängig vom Fahrmotor des Fahrzeuges angetriebene Baueinheit einer Brennkraftmaschine mit Generator ermöglicht es, ohne Gefahr für die Ladebilanz auch bei stillstehendem Fahrzeug mit ausgeschaltetem Fahrmotor eine größere Zahl von elektrischen Stromverbrauchern zu versorgen. Dies können auch Verbraucher sein, die nicht fahrzeuggebunden sind, beispielsweise Kühlschränke, Heizungen oder Gebläse in einem Wohnwagen. Weiterhin läßt sich die Abwärme der Antriebsmaschine des Generators für den Betrieb einer Standheizung oder für die Ergänzung einer solchen Standheizung nutzen.The one that is driven independently of the vehicle's drive motor Unit of an internal combustion engine with generator makes it possible, even at no risk to the loading balance stationary vehicle with the drive motor switched off a larger number of electrical electricity consumers too supply. This can also be consumers who are not are vehicle-bound, for example refrigerators, Heaters or blowers in a caravan. Farther the waste heat from the engine of the Generator for the operation of a parking heater or for use the addition of such an auxiliary heater.

Die Erfindung und weitere vorteilhafte Einzelheiten der Erfindung, die auch Gegenstand von Unteransprüchen sind, sind im folgenden anhand eines in der Zeichnung darge­ stellten Ausführungsbeispieles näher erläutert. Die Zeichnung zeigt einen schematisierten Teilquerschnitt durch den Heckbereich eines Personenkraftwagens.The invention and further advantageous details of the Invention, which are also the subject of dependent claims, are Darge below using one in the drawing presented embodiment explained in more detail. The Drawing shows a schematic partial cross section through the rear of a passenger car.

Mit 1 ist der Boden des Kofferraums des Kraftfahrzeuges angedeutet, an den seitliche Wandungen 2 anschließen. Von dem Kofferraumboden erstreckt sich die Reserverad­ mulde 3 nach unten. Seitlich dieser Reserveradmulde 3 ist ein Nachschalldämpfer 4 und - auf der anderen Seite - ein Brennstoffbehälter 5 dargestellt. Der elektrische Generator 6 des Personenkraftwagens, der dessen Bordnetz versorgt, ist durch eine von dem (nicht dargestellten) Fahrmotor des Fahrzeuges unabhängige Brennkraftmaschine 7 angetrieben. Der Generator 6 wird also von einer zusätzlichen kleinen Brennkraftmaschine mit einer entsprechenden Leistungsabgabe betrieben. Diese Brenn­ kraftmaschine 7 ist, wie sich aus dem Teilschnitt ergibt, im Heck des Kraftfahrzeuges angeordnet, und zwar im wesentlichen in der Reserveradmulde 3 des Fahrzeuges. Wie man sieht, ist für die Aufnahme der Brennkraft­ maschine 7 im wesentlichen der durch die Radschüssel 8 des Reserverades 9 umschlossene Raum genutzt.The bottom of the trunk of the motor vehicle is indicated by 1 , to which side walls 2 connect. The spare wheel well 3 extends downward from the trunk floor. To the side of this spare wheel well 3 is a rear silencer 4 and - on the other side - a fuel tank 5 . The electric generator 6 of the passenger car, which supplies the vehicle electrical system, is driven by an internal combustion engine 7 which is independent of the drive motor (not shown) of the vehicle. The generator 6 is therefore operated by an additional small internal combustion engine with a corresponding power output. This internal combustion engine 7 , as can be seen from the partial section, is arranged in the rear of the motor vehicle, essentially in the spare wheel well 3 of the vehicle. As you can see, for the inclusion of the internal combustion engine 7 essentially the space enclosed by the wheel bowl 8 of the spare wheel 9 is used.

Dies kann beispielsweise in der Weise erfolgen, daß die Brennkraftmaschine 7 und der Generator 6 in einer nach oben ausgeformten Auswölbung 10 des Muldenbodens 11 mit annähernd zur Kontur der Radschüssel 8 parallelen Wandungen 12 angeordnet ist. Wie man ferner erkennen kann, sind der Generator 6 und die Brennkraftmaschine 7 zu einer Baueinheit zusammengefaßt, die in der Reserve­ radmulde 3 angeordnet ist.This can be done, for example, in such a way that the internal combustion engine 7 and the generator 6 are arranged in an upwardly shaped bulge 10 of the trough bottom 11 with walls 12 parallel to the contour of the wheel disc 8 . As can also be seen, the generator 6 and the internal combustion engine 7 are combined to form a structural unit which is arranged in the wheel well 3 in the reserve.
