Abstract

The alternator is fitted above the engine timing case cover and driven by pulley belt from the fan drive-shaft. The drive belt is adjustable by mounting the alternator on a pivot bracket in the usual manner. The advantage is gained when used in amphibious craft, since the alternator will be above the water line and no special water sealing will be required. The drive belt may be a 'V' belt.

Die Erfindung betrifft einen Antrieb der Wechselstrom-Lichtmaschine einer luftgekühlten Brennkraftmaschine für insbesondere Nutzfahrzeuge, Amphibien wag en od. dgl.The invention relates to a drive for the alternating current generator of an air-cooled internal combustion engine, in particular for commercial vehicles, Amphibian wagons or the like

Bei bekannten derartigen Antrieben wird der Wechselstromgenerator bzw. die Lichtmaschine von der Kurbelwelle oder der Nockenwelle des Motors angetrieben und ist gewöhnlich am vorderen Deckel des Motorgehäuses in der Nähe des Kurbelwellen- oder Nockenwellenaustritts angebracht.In known drives of this type, the alternator or alternator is controlled by the crankshaft or the camshaft of the engine and is usually on the front cover of the engine housing near the crankshaft or camshaft exit appropriate.

ORIGINAL INSPECTEQORIGINAL INSPECTEQ

Ein Nachteil dieser Antriebe von Wechselstrom-Lichtmaschinen besteht darin, daß die Kurbelwelle und die Nockenwelle mit mehrfach kleineren Drehzahlen umlaufen als der Läufer des Wechselstromgenerators, so daß die Übersetzung des Generatorantriebes daher sehr groß sein muß, z. B. 1 : 3 und mehr. Ferner ergeben sich Schwierigkeiten bei der Anordnung, insbesondere bei Nutzfahrzeugen oder speziellen Wasserfahrzeugen, weil der in der Nähe des Kurbelwellen- oder des Nockenwellenaustritts sitzende Generator das Niveau des Schwellwasserschutzes wesentlich erniedrigt.A disadvantage of these drives for alternating current alternators is that the crankshaft and the camshaft with multiple rotate at a lower speed than the rotor of the alternator, so that the translation of the generator drive must therefore be very large, for. B. 1: 3 and more. Difficulties also arise in the arrangement, especially in commercial vehicles or special water vehicles, because the near the crankshaft or the generator seated at the camshaft outlet, the level of the surge protection significantly degraded.

Aufgabe der Erfindung ist die Schaffung eines Antriebes für die hochtourig umlaufende Wechselstromlichtmaschine ohne die bisher notwendigen hohen Übersetzungen.The object of the invention is to create a drive for the high-speed rotating alternator without the previously necessary high gear ratios.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß auf der Antriebswelle eines Ventilators eine Riemenscheibe aufgezogen ist, die den auf dem Gehäuse der Steuerwellenräder der Maschine angeordneten Generator über einen Keilriemen und eine weitere Riemenscheibe antreibt. This object is achieved in that on the Drive shaft of a fan a pulley is drawn, which is arranged on the housing of the control shaft wheels of the machine Drives generator via a V-belt and another belt pulley.

Im folgenden wird eine Ausführung des Antriebes nach der Erfindung anhand der Zeichnung ausführlich beschrieben. Es zeigen:The following is an embodiment of the drive according to the invention described in detail using the drawing. Show it:

Der Wechselstromgenerator 1 ist an Angüssen 4, 4' des Deckels 2 des Gehäuses 3 der Steuerwellenräder gelagert. Auf einer Antriebswelle 6 für ein Kühlgebläse 7 ist eine Riemenscheibe 5 befestigt, von der das Drehmoment der Welle 6 auf eine Riemenscheibe 10 des Wechselstromgenerators 1 durch einen Keilriemen übertragen wird- Die Spannung der Riemenscheibe 11 wird auf eine bekannte Art mit Hilfe einer Führung 8, die auf dem Anguß 4 des Deckels 2 gehalten ist, und mittels einer am Wechselstromgenerator 1 angebrachten Schraube 2 durchgeführt. ■The alternator 1 is on sprues 4, 4 'of the cover 2 of the housing 3 of the control shaft gears. A belt pulley 5 is attached to a drive shaft 6 for a cooling fan 7, from of the torque of the shaft 6 on a pulley 10 of the alternator 1 is transmitted through a V-belt- The tension of the pulley 11 is in a known way with the help of a guide 8 which is held on the sprue 4 of the cover 2, and carried out by means of a screw 2 attached to the alternator 1. ■

Einen Vorteil der Vorrichtung nach der Erfindung bildet der Umstand, daß es zur Übertragung des Drehmoments nicht nötig ist, große Versetzungen zu benutzen, da die Drehzahlen des Ventilators ungefähr die gleichen sind wie die erforderlichen Generator drehzahlen.One advantage of the device according to the invention is the fact that it is not necessary to transmit the torque, large Use offsets as the fan speeds are approximate are the same as the required generator speeds.

Einen weiteren wesentlichen Vorteil bildet die Anbringung des Wechselstromgenerators am Deckel des Gehäuses der Steuerwellenräder, was insbesondere bei Nutzfahrzeugen und bei speziellen Wasserfahrzeugen von Bedeutung ist. Durch diese Anordnung wird das Niveau des Schwellwasserschutzes dieser Fahrzeuge erhöht, und es ist nicht notwendig, die wesentlich schwereren und kostspieligeren wasserdichten Wechselstromgeneratoren einzusetzen. - Another significant advantage is the fact that the alternator is attached to the cover of the control shaft gear housing, which is especially true for commercial vehicles and special watercraft matters. This arrangement increases the level of swell protection of these vehicles, and it is not necessary to use the much heavier and more expensive waterproof alternators. -
