Description

Kurbelgetriebe für Zweizylindermotoren. Bei Zweitaktmotoren ist es unter Umständen zweckmäßig; zwei Arbeitszylinder durch einen gemeinsamen Kompressionsraum miteinander zu verbinden, so daß der eine Kolben den Einlaß, der andere den Auspuff steuert. Bei diesen Motoren müssen die beiden Arbeitskolben gleiphlaufen, damit die Steuerung richtig ist.Crank gear for two-cylinder engines. With two-stroke engines it is possibly useful; two working cylinders through a common compression space to connect with each other, so that one piston is the inlet, the other the exhaust controls. In these engines, the two working pistons must slide so the controls are correct.

Es sind Motoren bekannt, bei denen zwei Kurbelwellen nebeneinander angeordnet sind, welche durch Zahnräder miteinander verbunden sind. Dadurch wird aber der Motor sehr kompliziert und teuer, und außerdem machen die Zahnräder Yiel Lärm.Motors are known in which two crankshafts are side by side are arranged, which are connected to one another by gears. This will but the engine is very complicated and expensive, and besides, the gears make yiel Noise.

Ferner ist es bekannt, die beiden Treibstangen der Arbeitszylinder unten starr miteinander zu verbinden und an einer Kurbel angreifen zu lassen. Diese Ausführung ist aber sehr schlecht, da sie ihren Zweck nicht erfüllt; denn die Kolben laufen dadurch nicht mehr gleich, haben verschieden große Beschleunigungskräfte und wird dadurch die Treibstange und die Zylinderwandung- stark beansprucht.It is also known that the two drive rods of the working cylinder to be rigidly connected to each other at the bottom and to be attacked by a crank. These But execution is very bad because it does not serve its purpose; because the pistons therefore no longer run the same, have different acceleration forces and as a result, the drive rod and the cylinder wall are heavily stressed.

Die vorliegende Erfindung betrifft eine Konstruktion, bei der beide Zylinder auf eine Kurbel arbeiten und die Nachteile der bekannten Ausführungen vermieden werden. Diese Konstruktion ermöglicht es, auch die Kurbelwelle senkrecht zur Ebene der Zylinderachsen anzuordnen.The present invention relates to a construction in which both Cylinder work on a crank and the disadvantages of the known designs avoided will. This construction also allows the crankshaft to be perpendicular to the plane to arrange the cylinder axes.

Die Scheiben 3 sitzen- auf der Lagerbüchse 2 fest und sind durch die Bolzen welche zür - Lagerung der Treibstangen 6 dienen miteinander verbunden. Die Treibstangen 6 sind an einer Seite verzahnt und greift diese Verzahnung in das Zahnrad q. ein. Das Zahnrad ¢ ist drehbar auf der Büchse 2. Dadurch, daB die Treibstangen durch das Zahnrad ¢ miteinander verbunden sind, müssen sie immer parallel zueinander bleiben und, da sie oben im Zylinder geführt sind, muB auch das Stück 3 immer horizontal bleiben. Es müssen also auch die Kolben immer Bleichlaufen.The discs 3 sit firmly on the bearing bush 2 and are through the Bolts which are used for - storage of the connecting rods 6 connected to one another. the Driving rods 6 are toothed on one side and this interlocking engages into the gear q. a. The gear wheel ¢ can be rotated on the sleeve 2. Because The connecting rods are connected to each other by the gearwheel ¢, they always have to remain parallel to each other and, since they are guided in the top of the cylinder, must also the piece 3 always remain horizontal. So the pistons always have to run bleach.
