Description

Drosselspule für elektrische Fahrzeuge. ,An. Drosselspulen für elektrische Fahrzeuge werden hohe Ansprüche hinsichtlich des Gewichtes und der Abmessungen, die möglichst gering-sein müssen, gestellt.Choke coil for electric vehicles. ,At. Choke coils for electrical Vehicles have high demands in terms of weight and dimensions, which must be as low as possible.

Um diesen Bedingungen nachzukommen, werden die in verschiedenen elektrischen kreisen eingeschalteten Wicklungen von Drosselspulen für elektrische Fahrzeuge entweder öl- oder luftgekühlt und erhalten einer- zwangsläufigen Umlauf des T@ühlmediums. Eine derartige nhleinrichtung stellt stets ein bestimmtes Mehrgewicht dar und nimmt ziemlich viel.Raum in Anspruch. _ Am Fahrzeugdach angeordnete Drosselspulen werden zwar durch bei der-Fahrt strömende Luft teilweise gekühlt, jedoch strömt diese Luft hier ungeordnet und-wird zu einer intensiven Kühlung nicht voll ökonomisch ausgenutzt. Eine auf diese natürliche Axt gekiihlte Drosselspule ist ziemlich groß und. schwer und von einer großen Menge aktiven Materials. Oft kann man dieselbe nicht in dem verlangten Raum unterbringen, da man hierdurch das 'zulässige-Normalprofil @berscrlreiten würde. Diese äLchtei 1e werden durch die Erfindung beseitigt. Die Erfindung, schafft eine gleichmäßige 'intensive Kühlung sämt- licher Windungen von Scheibendrosselspuler_ durch die besondere Formung Sand n.nordnurg von Schutzhauben für diese Spulen. Das Wesen der Erfinduilg besteht darin, daß im Innern einer jeden Scheibenspule eine Trennwand vorgesehen ist, um eine freie Luftströmung durch den freien zylindrischen Raum im Inneren der E;cheibens:ulen zu verhindern, so daß die-,gesamte strömende Luft für die rühlung der Scheibenspule ausgenutzt wird. Oberhalb und unterhalb der ücheibenspulen sind geformte Schutzhauben aus Isoliermaterial angeordnet. Zwischen der Scheibenspule und den geformten Schutzhauber_ sind radiale Kühlungskanäle ausgebildet, die der, Eintritt der @:ühlluft -in die ,xiallranG.1e, und zwar bei beiden Fahrtrichtux-gen des Fahrzeug-es, ih gleicher Weise ermöglichen. Das Wesen der Erfindung ist an in der Zeich...rüng scheratisch dargestellten Ausführungsbeispielen nö.her erläutert-. Es zeigen: Fig. 1 eine durch eine. Scheibenspule ausgebildete Droesel- spulenwicklung, , Fig. 2 den Gründriß der Drosselspule der Fig.'1, Fig. 3 eine aus zwei Scheibenspulen gebildete Drosselspulen- wicklung. Zwischen den.einzelnen Windungen der Scheibenspule 1 (Fig. 1) sind Distanzeinlagen angeordnet, zwischen denen . die axialen Kühlungskanäle 2 verlaufen: Im Innern der Drosselspule ist eine Trennv=and. 5 vorgesehen, die eine freie Durchströmung der Luft durch den mittleren zylindrischen freien Raum der Scheibenspule verhindert.-Oberhalb und unterhalb der Drosselspüle sind geformte Schutzhauben 6 aus Isolierstoff angeordnet, deren R.nder zur Hälfte an dem Scheibenspulenumfang anliegen und zusammen mit der Scheibenspule 1 radiale Kühlungskanäle 3 bilden. Die obere Schutzhaube 6 .öffnet sieh zu der entgegengesetzten Seite als die untere . Schutzhaube, =so daß bei der Fahrt in einer Richtung die Kühlluft in Richtung 7 entsprechend den vollen lfeilen strömt. Dei der Fahrt in eii'tLe,#,;engesetzter Richtung strömt die Kühlluft in er_itgegenr.esetüter Richtung entsprechend den punktiert angedeuteten !-feinen. ` In Fig.r 2 =st dieselbe Wic=,:I;,",t..rr@,a:@cri Zur @@er@@x@@ci-_au- lichung aer rlrennwand 5 iri. i.n__eria ü@:@ ;rc eihensr@ule 1, der geformten cliutzhaube 6 und Jer üitarzenla-=en 4 dargestellt.

Such a sewing device always represents a certain additional weight and takes up quite a lot of space. _ Choke coils arranged on the vehicle roof are partially cooled by the air flowing during the journey, but this air flows in a disordered manner and is not fully economically used for intensive cooling. A choke coil cooled on this natural ax is quite large and. heavy and of a large amount of active material. Often one cannot accommodate it in the required space because one thereby the 'permissible normal profile would @berscrlreit. These defects are eliminated by the invention. the Invention, creates a uniform 'intensive cooling of all- licher turns of disc choke coil_ by the special Forming sand n.nordnurg from protective hoods for these coils.
