Description

Die Erfindung bezieht sich auf eine Brennkraftmaschine mit Luftpresser welcher nach dem Verdrängerprinzip arbeitet und der ausgehend von einer Kurbelwelle der Brennkraftma­ schine unter Zwischenschaltung von Zahnrädern angetrieben wird.The invention relates to an internal combustion engine Air compressor that works on the displacement principle and that based on a crankshaft of the internal combustion engine machine driven with the interposition of gears becomes.

Luftpresser von Nutzfahrzeugen werden üblicherweise als Kolbenverdichter ausgeführt, welche von einer Kurbelwelle der Brennkraftmaschine angetrieben werden. Die Übertragung des Antriebsdrehmoments von der Kurbelwelle der Brennkraft­ maschine auf die Kurbelwelle des Kolbenverdichters erfolgt mittels Keilriemen oder durch Zwischenschaltung von Zahn­ rädern. Zahnräder als Übertragungsmittel gewährleisten weitestgehende Wartungsfreiheit. Bei Verwendung von Zahn­ rädern tritt allerdings das Problem erheblicher Geräusch­ emission auf, da der Kolbenverdichter eine ausgesprochen pulsierende Drehmomentcharakteristik aufweist. Besonders beim Überschreiten des oberen Totpunktes tritt durch Nach­ expansion eine Änderung des Vorzeichens des Drehmoments ein, wodurch ein Abheben der Zahnflanken erfolgt. Anschließend schlagen die Zahnflanken wieder aufeinander und führen zu der vorgenannten Geräuschemission. Darüber hinaus führt der pulsierende und sich im Vorzeichen ändernde Drehmomentver­ lauf zu Zahnbrüchen.Air compressors of commercial vehicles are usually called Piston compressor executed by a crankshaft the internal combustion engine are driven. The transfer of the drive torque from the crankshaft of the internal combustion engine machine on the crankshaft of the piston compressor by means of V-belts or by interposing tooth wheel. Ensure gears as a transmission medium largely maintenance-free. When using tooth However, wheels experience the problem of considerable noise emission on because the piston compressor pronounced a has pulsating torque characteristics. Especially when exceeding the top dead center occurs by Nach expansion changes the sign of the torque, whereby the tooth flanks are lifted off. Subsequently  the tooth flanks hit each other again and lead to the aforementioned noise emission. In addition, the pulsating and changing torque sign run to broken teeth.

Der Erfindung liegt daher die Aufgabe zugrunde, den Luft­ presser so auszubilden, daß bei Verwendung von Zahnrädern zur Drehmomentübertragung die Geräuschemission drastisch vermindert und die Lebensdauer der Zahnräder erhöht wird.The invention is therefore based on the object, the air train the presser so that when using gears noise transmission drastically for torque transmission reduced and the life of the gears is increased.

Gelöst wird diese Aufgabe dadurch, daß der Luftpresser als Rotationsverdichter ausgebildet ist.This problem is solved in that the air compressor as Rotary compressor is formed.

Der Rotationsverdichter hat ein nahezu gleichförmiges Dreh­ moment. Eine Vorzeichenumkehr des Drehmoments ist ausge­ schlossen. Daraus resultiert, daß die bei Kolbenverdichtern unangenehme Geräuschemission durch den Zahnflankenwechsel unterbleibt. Ferner wird die Lebensdauer der Zahnräder er­ höht, da sie keiner wechselnden Beanspruchung unterworfen sind. Das bei Nutzfahrzeugen erforderliche Druckniveau der Bremsluft wird durch den ebenfalls nach dem Verdrängerprin­ zip arbeitenden Rotationsverdichter ohne weiteres ebenso erreicht, wie durch den sonst üblichen Kolbenverdichter.The rotary compressor has an almost uniform rotation moment. A sign reversal of the torque is out closed. The result of this is that with piston compressors unpleasant noise emission due to the tooth flank change is omitted. Furthermore, the life of the gears he increases, since it is not subject to changing loads are. The pressure level required for commercial vehicles Brake air is also by the displacer zip-working rotary compressor as well achieved, as by the otherwise usual piston compressor.

Eine vorteilhafte Weiterbildung der Erfindung zeichnet sich dadurch aus, daß als Rotationsverdichter ein Schraubenver­ dichter verwendet wird.An advantageous development of the invention is distinguished characterized in that as a rotary compressor a screw ver is used more densely.

Der Schraubenverdichter arbeitet wegen der Berührungsfrei­ heit unter den Spindeln nahezu verschleißfrei. Außerdem weist er ein wesentlich geringeres Bauvolumen auf als ein vergleichbarer Kolbenverdichter und eignet sich auch aus diesem Grund besonders bei Nutzfahrzeugen. The screw compressor works because of the non-contact almost wear-free under the spindles. Furthermore it has a much smaller volume than one comparable piston compressor and is also suitable for this reason, especially for commercial vehicles.  

Ein weiteres Merkmal besteht nach Anspruch 3 darin, daß als Rotationsverdichter ein Flügelzellenverdichter ange­ wendet wird. Auch der Flügelzellenverdichter ergibt ein gleichförmiges Drehmoment und führt zu einer Verminderung der Geräuschemission und einer Lebensdauerverlängerung der Zahnräder.Another feature according to claim 3 is that a vane compressor as a rotary compressor is applied. The vane compressor also gives a uniform torque and leads to a decrease the noise emission and a life extension of the Gears.
