Description
Gegenstand der Erfindung ist eine Einrichtung zur Totpunktüberwindung an der Kurbelwelle von Verbrennungsmotoren und Dampfmaschinen, bei der ein Kraftübertragungshebel zur Anwendung kommt, der den Angriffspunkt. der Kolbenstange von -dem Kurbelzapfen auf das freie Ende des Hebels verlegt, so daß der Arbeitsweg verlängert und der Leerlaufrückweg verkürzt wird. ' Es sind bereits Einrichtungen zur Totpunktüberwindung an der Kurbelwelle von Verbrennungsmotoren bekannt. Es kommt dabei ein einfacher Kraftübertragungslhebel zur Anwendung,. der in einer Kulisse oder an enneir Schwinge geführt wird.The invention relates to a device for overcoming dead center on the crankshaft of internal combustion engines and steam engines with a power transmission lever is used, which is the point of attack. the piston rod from the crank pin Relocated to the free end of the lever, so that the work path is extended and the Idle return travel is shortened. 'There are already facilities to overcome dead center known on the crankshaft of internal combustion engines. There is a simple one Power transmission lever for use. in a backdrop or on a swing arm to be led.
Bei diesen bekannten Einrichtungen muß für jeden Zylinder bzw. jeden Kolben ein besonderer Kraftübertragungshebel angeordnet werden.In these known devices must for each cylinder or each Piston a special power transmission lever can be arranged.
Dieser Nachteil wird beim Gegenstand nach der Erfindung dadurch beseitigt, daß im Bereiche zweier Zylinder zwei Kurbelwellen parallel zueinander gelagert und durch Zahnräder gegenläufig miteinander verbunden sind, wobei die Kurbeln um 18o° zueinander versetzt sind und eine zweiteiliger Kraftübcrtragungshebel zur Anwendung kommt, der in der Längsrichtung in sich verschiebbar ist und an dessen beiden Enden die Angriffspunkte für die beiden Kolbenstangen liegen.This disadvantage is eliminated in the object according to the invention, that in the area of two cylinders two crankshafts are mounted parallel to each other and are connected to each other by gears in opposite directions, the cranks by 180 ° are offset from one another and a two-part power transmission lever is used comes, which is slidable in the longitudinal direction and at both ends the points of application for the two piston rods are.
Auf diese Weise ist mit Hilfe verhältnismäßig weniger Bäuteile ein zweckmäßiges Getriebe mit Totpunk'tüberwindung für jeweils zwei Zylinder geschaffen, die im Gegentakt zueinander arbeiten.In this way, there is relatively fewer building parts with the help appropriate gearbox with dead center overcoming created for two cylinders each, that work in push-pull to each other.
Vorzugsweise sind die Zylinder mit ihren-Längsachsen auf den Mittelpunkt der aus Arbeits- und Leerlaufrückweg gebildeten Doppelkurve bzw. auf die günstigste Richtung der Arbeitskurve. ausgerichtet.The cylinders are preferably with their longitudinal axes on the center the double curve formed from the working and idling return path or to the cheapest one Direction of the working curve. aligned.
Die Zeichnung veranschaulicht den Erfindungsgegenstand in einem Ausführungsbeispiel.The drawing illustrates the subject matter of the invention in an exemplary embodiment.
An zwei Kurbelwellen 1, 2 ist je eine Kurbel 3, 4 angebracht. Ein zweiteiliger Kraftübertragungshebel 5, 6 ist durch ein Schiebestück 7, das am Teil 6 angebracht ist und in eine Bohrung 8 des anderen Teiles 5 hineinragt, in der Längsrichtung verschiebbar und an den beiden Kurbelzapfen 9 und io befestigt. An den überragenden Enden i i und 12 greifen bei den Punkten 13 und 14 die Kolbenstangen 15 und 16 an.A crank 3, 4 is attached to each of two crankshafts 1, 2. A two-part power transmission lever 5, 6 is through a sliding piece 7 on the part 6 is attached and protrudes into a bore 8 of the other part 5, in the longitudinal direction slidable and attached to the two crank pins 9 and io. On the outstanding Ends i i and 12 engage piston rods 15 and 16 at points 13 and 14.
Die Zylinder 17 und 18 sind mit ihren Längsachsen schräg auf die äußere Kurve 1g gerichtet, welche jeweils die Angriffspunkte 13 und 14 der Kolbenstangen 15 und 16 bei der Kurbelumdrehung beschreiben.The cylinders 17 and 18 are oblique to the outer with their longitudinal axes Curve 1g directed, which respectively the points of application 13 and 14 of the piston rods 15 and 16 describe the crank rotation.
Auf den beiden Kurbelwellen i und 2 ist je ein Zahnrad 22 und 23 befestigt, die ineinandergreifen. Dadurch werden die beiden Kraftübertragungshebelteile 5, 6 an den beiden Kurbeln 3 und 4 zwangsweise gleichmäßig und gleichbleibend gesteuert. Hierdurch entstehen die Kurven i9 und 24 für den Kolbenhub, wobei die Hublänge immer die gleiche bleibt.A gear 22 and 23 is attached to each of the two crankshafts i and 2, that interlock. As a result, the two power transmission lever parts 5, 6 on the two cranks 3 and 4 forcibly evenly and consistently controlled. This creates curves i9 and 24 for the piston stroke, with the stroke length always remains the same.
Die Einrichtung kann bei allen Verbrennungskraftmaschinen - sowie bei Dampfmaschinen Anwendung finden.The device can be used with all internal combustion engines - as well as find application in steam engines.
