Description

Brennkruftelektrischer Antrieb von Amphibienfahrzeuges Die vorliegende Erfindung betrifft einen brennkraftelektrischen Antrieb eines Amphibienfahrzeuges, bei dem die von der Verbrennungskraftmaschine gelieferte mechanische Leistung zum Antrieb von elektrischen Fahrmotoren in elektrische Leistung umgewandelt wird. Bei diesem Amphibienfahrzeug soll der Antrieb der für die Wasserfahtt dienenden Schiffsschrauben so ausgebildet sein, daß die Schiffeschrauben auch zur Fahrrichtungsänderung verwendet werden können, d.h. sie müssen mit unterschiedlichen Drehzahlen betrieben werden können. Zur Lösung dieser Aufgabe werden gemäß der Erfindung als Schraubenmotoren asynchrone Kurzschlußläufermotoren angewendet, die vom Wasser um- u'nd/oder durchspüli werden und mit der Schiffsschraube direkt oder über ein Zwischengetriebe verbunden sind und die Schraubenmotoren werden von einer Wechselspannung gespeist, deren Frequenz der Drehzahl der Verbrennungskraftmaschine proportional ist und deren Größe verändert werden kann. Die Drehzahl jedes Schraubenmotors kann mithin auf einfachste Weise, nämlich durch Änderung der Größe der zugeführten Spannung, geregelt werden. Außerdem hat der Antrieb den Vorteil, daß der Aufbau der Schra,ubenmotoren durch den Kurzschlußläufer einfach und robust ist und insbesondere durch die Ausnutzung des durchfahrenen Wassers zur Abführune, der Verlustwärme sehr klein gehalten werden kann. Da jede S)chraube von einem eigenen Motor angetrieben wird, kann auch die Drehzahl jeder Schiffsschraube unabhängig von der anderen geändert werden, wenn eine Fahrrichtungsänderung#. erwünscht ist.Internal combustion-electric drive for amphibious vehicles The present invention relates to an internal combustion-electric drive for an amphibious vehicle, in which the mechanical power supplied by the internal combustion engine is converted into electrical power for driving electric traction motors. In this amphibious vehicle, the drive of the propellers used for the waterway should be designed so that the propellers can also be used to change the direction of travel, ie they must be able to be operated at different speeds. To solve this problem, asynchronous squirrel cage motors are used as screw motors according to the invention, which are um- u'nd / or flushed by the water and are connected to the propeller directly or via an intermediate gear and the screw motors are fed by an alternating voltage, the frequency of which is the speed the internal combustion engine is proportional and its size can be changed. The speed of each screw motor can therefore be regulated in the simplest possible way, namely by changing the size of the voltage supplied. In addition, the drive has the advantage that the construction of the screw motors is simple and robust due to the squirrel cage and, in particular, by using the water passed through for discharge, the heat loss can be kept very small. Since each propeller is driven by its own motor, the speed of each propeller can also be changed independently of the other when a change of direction #. is desired.

Es empfiehlt sich, die Veränderung der Schraubenmotorenspannung mit Hilfe eines regelbaren Umspanners vorzunehmen, Man kann aber auch für jeden Schraubenmotor einen eigenen Generator vorsehen, dessen Erregerstrom dann zur Erzielung der gewüiischten Drehzahländerung verändert wird. Eine weitere Ivlöglichkeit der*Drehz ahländerung der Schiffsschrauben ergibt sich durch eine Veränderung der Drehzahl der Verbrennungskraftmaschine und - falls erforderlich - durch Polumschaltung des Schraubenmotors. Es empfiehlt sich, die Polumschaltung vorzugsweise im Verhältnis 3 : 4 auszuführen, um die Schlupfverluste bei kleinen Geschwindigkeiten des Fahrzeuges zu CD vermindern.It is advisable to change the screw motor voltage with the help of an adjustable transformer, but you can also provide a separate generator for each screw motor, the excitation current of which is then changed to achieve the desired change in speed. Another possibility of changing the speed of the propellers results from changing the speed of the internal combustion engine and - if necessary - by changing the pole of the screw motor. It is advisable to switch the pole preferably in a ratio of 3: 4 in order to reduce the slip losses at low speeds of the vehicle to CD.

Ausführungsbeispiele der Erfindung sind in den Figuren 1 und 2 dargestellt.Exemplary embodiments of the invention are shown in FIGS. 1 and 2.

P gur 1 zeigt schematisch den Aufbau des Antriebes eines Imphibienfahrzeuges, das mit Hilfe einer Verbrennungskraftmaschine 1 anget:#ieben wird. Da das Amphibienfahrzeug jedoch nur elektrische,Fahrmotoren besitzt, wird die von der Verbrennungskraftmaschine 1 gelieferte mechanische Leistung in elektrische Leistung umgewandelt. Zu diesem Zweck ist auf der Welle der Verbrennungskraftmaschine 1 der Generator 2 angeordnet, an dessen 2.214-Umen eine Wechselspannung abgenommen wird. Diese Ylechselspannung kann wahlweise über einen nicht dargestellten Umschalter entweder dem Gleichrichter 3 oder dem Umspanner 4 zugeführt werden. Der Gleichrichter 3 dient für die Fahrten auf dem Lande,.bei denen die im Gleichrichter 3 gleichgerichtete Wechselspannung des Generators 2. einen oder mehrere Gleichstromfahrmotoren 5 speist. Die Verwendung von Gleichstromfahrffiotoren hat den Vorteil, daß die Geschwindigkeit des Amphibienfahrzeuges leicht geregelt werden kann. P gur 1 shows schematically the structure of the drive of an immunization vehicle that is driven with the help of an internal combustion engine 1 . However, since the amphibious vehicle only has electric traction motors, the mechanical power supplied by the internal combustion engine 1 is converted into electrical power. For this purpose, the generator 2 is arranged on the shaft of the internal combustion engine 1 and an alternating voltage is drawn from its 2.214 Umen. This Ylechsel voltage can optionally be fed to either the rectifier 3 or the transformer 4 via a changeover switch (not shown). The rectifier 3 is used for trips in the country. In which the rectified AC voltage of the generator 2 in the rectifier 3 feeds one or more DC traction motors 5. The use of DC traction motors has the advantage that the speed of the amphibious vehicle can be easily regulated.

Bei Fahrten auf dem Wasser wird die Wechselspannung des Generators 2 dem Umspanner 4 zugeführt, der zwei Sekundär.#-wicklungen besitzt. Jede Sekundärwicklung ist mit einem Schraubenmotor 6 bzw. 7 verbunden, die direkt oder über ein Zwischengetriebe die Schraube antreiben. Die Schraubenmotoren 6, 7 sind asynchrone Kurzschlußläufermotoren. Sie sind von dem Wasser, in dem sich das Amphibienfahrzeug bewegt, durchströmt, so daß sie ihre Verlustwärme direkt an die Umgebung abgeben. Dadurch können sie sehr klein gehalten werden. Zur Regelung der Drehzahl der Schraubenmotoren 6 und 7 wird die an den Sekundärwicklungen dis Umspanners 4 abgenommene Spannung verändert. Der Umspanner 4 ist dazu so ausgebildet, daß er bei gegebener Primärspannung eine Veränderung der Sekundärspannungen unabhängig voneinander, stufenlos oder in Stufen, gestattet.When driving on the water, the alternating voltage of the generator 2 is fed to the transformer 4, which has two secondary # windings. Each secondary winding is connected to a screw motor 6 or 7 , which drive the screw directly or via an intermediate gear. The screw motors 6, 7 are asynchronous squirrel cage motors. The water in which the amphibious vehicle moves flows through them, so that they give off their heat loss directly to the environment. This allows them to be kept very small. To regulate the speed of the screw motors 6 and 7 , the voltage taken from the secondary windings of the transformer 4 is changed. To this end, the transformer 4 is designed in such a way that, for a given primary voltage, it allows the secondary voltages to be changed independently of one another, continuously or in steps.

Bei dem Ausführungsbeispiel gemäß Figur 2 ist jedem Schraubenmotor 6 und 7 ein Wechselapannungegenerator 8 bzw. 9 zugeordnet, die von der Verbrennungskraftmaschine 1 angetrieben werden. Die Veränderung der Schräubenmotorspannung erfolgt in diesem Fall über die Purregerströme der beiden Generatoren 8 bzw. 9, so daß auf einfache Weise*eine stufenlose Zinderung der Schraubenmotorenspannungen erzielt wird. Für Fahrten auf de.-.. 'Lande wird einer der Genratoren mit dem Gleichrichter 3 und den Gleichstromfahrmotoren 5 verbunden. Zur Platzersparnis empfiehlt es sich, beide Generatoren 8 und 9 mit dem Gleichrichter 3 in einem Gehäuse anzuordnen.In the exemplary embodiment according to FIG. 2, an alternating voltage generator 8 and 9 , which are driven by the internal combustion engine 1, is assigned to each screw motor 6 and 7. In this case, the screw motor voltage is changed via the purifier currents of the two generators 8 and 9, so that a stepless reduction in the screw motor voltages is achieved in a simple manner. One of the generators is connected to the rectifier 3 and the DC traction motors 5 for journeys on the land. To save space, it is advisable to arrange both generators 8 and 9 with the rectifier 3 in one housing.
