Description
- Kurbelwelle mit rotierendem, dezentral gelagerten, Kurbelzapfen -Anwendungsgebiet: Die Erfindung betrifft eine Kurbelwelle für Ottomotoren.- Crankshaft with rotating, decentrally mounted, crank pin -Application area: The invention relates to a crankshaft for gasoline engines.
Zweck: Durch die Erfindung soll eine bessere Ausnutzung der Kolbenkompression ermöglicht werden.Purpose: The invention aims to make better use of piston compression be made possible.
Kritik, Stand der Technik: Seit Anwendung der Kurbelwelle zur Kraftübertragung der Kolbenmotoren hat sich in ihrem Anwendungsprinzip nichts geändert. Sie überträgt die Kolbenkompression vom Oberen toten Punkt zudem Unteren, wobei sich, je nach Winkelstellung der Kurbel-Wangen, der Kolbenhub schneller oder langsamer vergrößert bezw. verkürzt. Die zur Kraftausnutzung günstigste Stellung des Kurbelarmes ist im Bereich von 90o zum Kolbenlauf, es ist dies euch die Stellung an der sich der Kolbenhub am schnellsten vergrößert.Criticism, state of the art: Since the use of the crankshaft for power transmission the principle of application of the piston engines has not changed. She transmits the piston compression from the upper dead point to the lower, whereby, depending on Angular position of the crank cheeks, the piston stroke increased faster or slower respectively shortened. The most favorable position of the crank arm for the use of force is in the range of 90o to the piston barrel, this is the position at which the Piston stroke increased fastest.
Bei zunehmender Drehzahl erreicht die Kurbelwelle und somit auch der Kolbenhub an dieser Stelle jedoch eine Ge;,chwindigkeit, welche derjenigen der Deflagration der Gase im Verbrennungs-Raum der Kolben annähernd gleich kommt und damit deren Dekompressionskraft nimmt. r Auf gab e Die wirkende Kraft auf den Kurbelwellenhebel in der Po@:; i. t i.on von cirka 900 besser ausnützen durch größere fsF:l.;@,arang in r1 ie"em Bereich.As the speed increases, the crankshaft and thus also the Piston stroke at this point, however, a speed which is that of deflagration of the gases in the combustion chamber of the pistons is approximately the same and thus their Decompression force takes. r up gave e the force acting on the crankshaft lever in the Po @ :; i. Better use t i.on of around 900 through larger fsF: l.; @, arang in r1 ie "em area.
1an@;: Dir: Kizrhf:lwel:Le erhält einen dezentrieri; gelagerten, Kurbelzapfen der den Pleuel verlängert oder verkürzt, wie es die momentane Position der Kurbelwelle, zur günstigen Ausnutzung der Kolbenkompression, erfordert.1an @ ;: Dir: Kizrhf: lwel: Le receives a decentrieri; bearing, crank pin which extends the connecting rod or shortened as it is the current position of the crankshaft, for the favorable utilization of the piston compression.
Dieser Kurbelzapfen (Zeichn. Pos..5) erhält einen inneren Zahnkranz (10) und ist in den Kurbelzapfen-Wangen (4) gelagert. Ebenfalls in den Kurbelz.-Wangen (4) gelagert sind das äußere Zahnrad (9) und das innere Zahnrad (8). Durch die Rotation der Kurbelwelle wird das Zahnr. (9) von dem Zahnkranz (7) der Kurbelwangen (6) angetrieben und über das innere Zahnr. (8) auf den inn. Zahnkranz (10) des Kurbelzapfen übertragen und diesen in Rotation gebracht.This crank pin (drawing Pos..5) has an inner ring gear (10) and is mounted in the crank pin cheeks (4). Also in the crank arm cheeks (4) the outer gear (9) and the inner gear (8) are mounted. Through the rotation the crankshaft is the tooth. (9) driven by the ring gear (7) of the crank webs (6) and about the inner tooth. (8) on the inn. Transfer the ring gear (10) of the crank pin and rotated it.
Wie aus der Schemazeichnung, Blatt 1, ersichtlich verlängert der Kurbelzapfen bei Pos. I und II den Pleuel, dadurch wird eine bessere, länger andauernde Kompression bis über die bereits oben erwähnten günstigen Kurbelhebelstellung von 90o zum Kolbenlauf erreicht. Bei Pos. III und IV wird der Pleuel wiederum verkürzt, der untere tote Punkt, nach Überschreiten der letzten Kompression giznstigen Hebelstellung, schneller erreicht und anschliessend länger gehalten, was eine bessere Zylinderfüllung ermöglicht. Vorteile: - Bessere Kraftausnutzung pro Hubraten Lind Ltr. Benzinverbrauch.As can be seen from the schematic drawing, sheet 1, the crank pin is extended at Pos. I and II the connecting rod, this results in a better, longer lasting compression up to the already mentioned favorable crank lever position of 90o to the piston run achieved. At pos. III and IV the connecting rod is shortened again, the lower dead one Point, after exceeding the last compression, favorable lever position, faster reached and then held longer, which enables better cylinder filling. Advantages: - Better utilization of force per stroke rate and liters of gasoline consumption.
- GeringererZylinderveruchleiß durch Verringerung der maximalen Kolbengeschwindigkeit pro Ki.irbeltuiidrehiuig. - Größere Kraftreserven bei geringerer Drelizaril.- Less cylinder wear by reducing the maximum piston speed per Ki.irbeltuiidrehiuig. - Greater power reserves with less drelizaril.
