Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand vorliegender Erfindung bildet eine Kühlungseinrichtung für zum Antrieb von Fahrzeugen dienende Elektromotoren. The subject matter of the present invention forms a cooling device for Electric motors used to drive vehicles.

Das Wesen der Erfindung besteht darin, daß der gekühlte Motor die Kühlluft von einem besonderen Ventilator erhält, welcher durch eine von einem zweiten kleineren Motor zeitweise- angetriebene Fahrzeugachse in Umdrehung versetzt wird.The essence of the invention is that the cooled engine, the cooling air of a special fan, which is powered by a second smaller motor temporarily driven vehicle axle is set in rotation.

Hierdurch wird es möglich, den zur Verfügung stehenden Raum zwischen den Rädern besser auszunutzen, indem an dem größeren Motor selbst keine Ventilationseinrichtung angebracht zu werden braucht, so daß derselbe den ganzen Raum zwischen den Rädern vollständig ausfüllen kann. Dagegen wird der an dem kleineren Hilfsmotor verbleibende Raum zwischen den Rädern zur Einbauung des Ventilators benutzt.This makes it possible to use the space available between the wheels better use by not having a ventilation device on the larger motor itself needs to be attached so that the same can completely fill the whole space between the wheels. Against it the space between the wheels on the smaller auxiliary motor is used to install the fan.

In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. In the drawing, an embodiment of the invention is shown.

α und b sind Drehstrommotoren, von denen der größere α während der Fahrt den Betrieb allein übernimmt, während b nur beim Anfahren eingeschaltet und mit a in Kaskadenschaltung verbunden ist. Auf der Achse, welche von dem Motor b angetrieben wird, sitzen die von ihr angetriebenen Ventilatoren c, ' welche mittels der Luftleitungen d dem Motor α sowohl beim Anfahren als während der Fahrt Luft zuführen. α and b are three-phase motors, of which the larger α takes over the operation while driving, while b is only switched on when starting and connected to a in a cascade connection. On the axle, which is driven by the motor b , sit the fans c, 'driven by it, which supply air to the motor α by means of the air lines d both when starting up and while driving.

Naturgemäß kann der Luftdruck auch durch die Ventilatorwirkung des Motors b selbst erzeugt werden.Of course, the air pressure can also be generated by the fan action of the motor b itself.

Endlich ist es für das Wesen der Erfindung gleichgültig, ob die Kühlluft immer von neuem aus dem Freien entnommen wird oder einen geschlossenen Kreis durchläuft und während desselben abgekühlt wird. ■Finally it is indifferent to the essence of the invention whether the cooling air is always from is taken from the open air or runs through a closed circle and while it is being cooled. ■
