Abstract

The invention relates to a drive for an electric car. It consists of a battery whose direct current is converted into alternating current by means of a converter (invertor). This alternating current supplies an alternating-current motor, which drives the car, via a transformer. The battery can be buffered via a dynamo connected to the alternating-current motor. <IMAGE>

Description

Die Erfindung betrifft einen Antrieb für ein Elektroauto mit einem Umformer von Gleichstrom in Wechselstrom.The invention relates to a drive for an electric car with a Converter from direct current to alternating current.

Ziel der Erfindung ist es, bei dem Antrieb mit möglichst wenigen bzw. kleinen Batterien auszukommen.The aim of the invention is to use as few or small batteries.

Erfindungsgemäß wird dies durch die Merkmale im Kennzeichen des Haupt­ anspruches bewirkt.According to the invention this is due to the features in the identification of the main claim causes.

Eine vorteilhafte Weiterentwicklung wird durch die Merkmale des Unteran­ spruches ermöglicht.An advantageous further development is due to the characteristics of the Unteran saying enables.

Anhand der Figur soll in folgenden ein Ausführungsbeispiel der Erfindung näher erläutert werden.Based on the figure, an embodiment of the invention is intended in the following are explained in more detail.

Der Strom aus der Batterie 6 wird durch einen Umformer in Wechselstrom umgeformt. Dieser Umformer besteht aus einem kleinen Elektromotor 1 mit geringem Stromverbrauch. Auf seiner Achse 2 sitzen zwei Schleifringe 3 und 4 sowie ein zweiteiliger Kollektor 5. Dieser Kollektor ist von einer Lamellenhälfte zur anderen soweit unterbrochen, daß die Kohlen zum Abgreifen des Stromes bei der Drehung der Achse 2 nicht gleichzeitig die Lamellenhälften berühren; dadurch wird ein Kurzschluß vermieden. Der Gleichstrom von der Batterie 6 fließt vom Pluspol bzw. Minuspol zu den beiden Schleifringen 3 bzw.4. Beim dargestellten Ausführungsbeispiel ist der Schleifring 3 mit der linken Kollektorhälfte und der Schleifring 4 mit der rechten Kollektorhälfte elektrisch leitend verbunden. The current from the battery 6 is converted into alternating current by a converter. This converter consists of a small electric motor 1 with low power consumption. Two slip rings 3 and 4 and a two-part collector 5 sit on its axis 2 . This collector is interrupted from one lamella half to the other so far that the coals for tapping the current do not simultaneously touch the lamella halves when axis 2 rotates; this avoids a short circuit. The direct current from the battery 6 flows from the positive pole and the negative pole to the two slip rings 3 and 4, respectively. In the illustrated embodiment, the slip ring 3 is electrically conductively connected to the left half of the collector and the slip ring 4 is connected to the right half of the collector.

Der Gleichstrom in den Schleifringen 3, 4 ändert seine Polarität nicht. Hingegen ist am Ausgang der Kollektorhälften 5 ein bei der Drehung der Achse 2 abgreifbarer Strom wechselnder Polarität vorhanden. Dieser Wechselstrom wird einem Transformator 7 zugeführt, an dessen Ausgangs­ seite eine entsprechend transformierte Wechselspannung zum Betreiben des Wechselstrommotors 8 dient, der den Autoantrieb bewirkt.The direct current in the slip rings 3, 4 does not change its polarity. On the other hand, at the output of the collector halves 5 there is a current of alternating polarity that can be tapped when the axis 2 rotates. This alternating current is fed to a transformer 7 , on the output side of which a correspondingly transformed alternating voltage is used to operate the alternating current motor 8 , which effects the car drive.

Durch die Anwendung eines Transformators anstelle von mehreren zusammen­ gefaßten Batterien ist es möglich, eine konstante Stromversorgung herzu­ stellen. In Weiterführung der Erfindung treibt der Wechselstrommotor 8 gleichzeitig einen Dynamo 9 an. Dessen Ausgangsspannung wird der Batterie 6 zugeführt, sodaß diese beim Betrieb gepuffert wird.By using a transformer instead of several batteries combined, it is possible to establish a constant power supply. In a continuation of the invention, the AC motor 8 simultaneously drives a dynamo 9 . Its output voltage is supplied to the battery 6 so that it is buffered during operation.

Die erfindungsgemäße Ausbildung des Antriebes ist umweltfreundlich und billig im Betrieb. Sie kann auch für stationären Betrieb Verwendung finden. Das Puffern erlaubt die Verwendung kleiner Batterien. Da der Antriebsmotor 1 im wesentlichen nur den Federdruck der vier Kohlen zu überwinden hat, kann auch er klein gehalten werden.The design of the drive according to the invention is environmentally friendly and inexpensive to operate. It can also be used for stationary operation. Buffering allows the use of small batteries. Since the drive motor 1 essentially only has to overcome the spring pressure of the four coals, it can also be kept small.
