HubkolbenmaschineReciprocating engine

Die Erfindung betrifft eine Hubkolbenmaschine mit mindestens einem Hubkolben, der über eine Pleuelstange mit einer Kurbelwelle verbunden ist.The invention relates to a reciprocating piston machine with at least one reciprocating piston which is connected via a connecting rod is connected to a crankshaft.

Hubkolbenmaschinen sind meist derart ausgebildet, daß ein Hubkolben über eine Pleuelstange mit der Kurbelwelle verbunden ist. Die durch die Schrägstellung der Pleuelstange verursachten Seitenkräfte des Kolbens auf ' die Zylinderwand haben "Reibungskräfte und entsprechende Reibungsverluste zur Folge. Kreuzkopfmaschinen vermeiden diese Nachteile und verlegen die Reibungsverluste zur Kreuzkopflaufbahn, erfordern jedoch einen erheblichen baulichen Mehraufwand. Der Kolben einer Hubkolbenmaschine ohne Kreuzkopf muß dagegen ausreichend hoch und gut geschmiert sein, damit er nicht zum Verkanten oder gar zum Klemmen neigt.Reciprocating piston machines are usually designed in such a way that a reciprocating piston is connected to the crankshaft via a connecting rod connected is. The lateral forces of the piston caused by the inclination of the connecting rod on ' the cylinder wall "result in frictional forces and corresponding frictional losses. Avoid cross-head machines these disadvantages and relocate the frictional losses to the crosshead raceway, however, require a considerable one additional structural effort. The piston of a reciprocating piston machine without a crosshead, on the other hand, must be sufficiently high and well lubricated so that it does not tend to tilt or even jam.

Der Erfindung liegt die Aufgabe zugrunde, eine Hubkolbenmaschine der eingangs genannten Art zu schaffen, bei der diese Nachteile vermieden sind. Diese Aufgabe wird mit bei einer Hubkolbenmaschine der genannten Art dadurch gelöst, daß der oder jeder Hubkolben über eine weitere, gleichlange Pleuelstange mit einer weiteren Kurbelwelle verbunden ist, und daß die beiden Kurbelwellen mit gleicher Drehzahl gegensinnig drehen.The invention is based on the object of creating a reciprocating piston machine of the type mentioned at the outset, in which these disadvantages are avoided. This task is achieved with a reciprocating piston engine of the type mentioned solved that the or each reciprocating piston via a further connecting rod of the same length with a further crankshaft is connected, and that the two crankshafts rotate in opposite directions at the same speed.

Eine Hubkolbenmaschine nach der Erfindung hat folgende Vorteile:A reciprocating piston engine according to the invention has the following advantages:

- Seitenkräfte zwischen Kolben und Zylinder werden vermieden.- Lateral forces between piston and cylinder are avoided.

- Der Hubkolben kann, weil er durch die beiden Pleuelstangen parallel geführt ist, besonders kurz ausgeführt werden.- The reciprocating piston can, because it is guided in parallel by the two connecting rods, especially be briefly carried out.

- Im Gegensatz zur konventionellen Hubkolbenmaschine sind die Massenkräfte einer nach der- In contrast to the conventional reciprocating engine, the inertial forces are one after the other

vorliegenden Erfindung ausgeführten Hubkolbenmaschine nahezu vollständig ausgeglichen , wenn entsprechende Gegenmassen an den beiden Kurbelwellen angebracht sind.present invention executed reciprocating piston engine almost completely balanced when appropriate counterweights are attached to the two crankshafts.

- Ein nach der Erfindung gestalteter Ottomotor kann als extremer Kurzhuber ausgeführt sein, was auch ohne Überschreitung üblicher Kolbengeschwindigkeiten hohe Hubraumleistung ermöglicht.- A gasoline engine designed according to the invention can be designed as an extreme short-stroke, which enables high displacement without exceeding the usual piston speeds.

- Der flache Arbeitsraum gestattet große Ventildurchmesser und damit gute Zylinderführung.- The flat working space allows large valve diameters and thus good cylinder guidance.

- Auch erfindungsgemäße Hubkolbenmaschinen mit sehr geringer Zylinderzahl oder gar mit nur einem Zylinder haben sehr kleine freie Massenkräfte und sind als Antriebsmotor für Personenkraftwagen geeignet.- Also reciprocating piston machines according to the invention with a very small number of cylinders or even with only one Cylinders have very small free inertia forces and are used as drive motors for passenger cars suitable.

- Die Baulänge der Hubkolbenmaschine ist sehr gering, was besonders bei frontgetriebenen Fahrzeugen mit kompaktem Antriebsblock vorteilhaft ist.- The overall length of the reciprocating piston engine is very short, which is especially true for front-wheel drive vehicles compact drive block is advantageous.

Ein Ausführungsbeispiel der Erfindung ist in Fig. 1 dargestellt: An embodiment of the invention is shown in Fig. 1:

Die beiden gegensinnig drehenden Kurbelwellen 1 und 2 sind über die beiden Zahnräder 3 und 4 miteinander im Eingriff. Die beiden gleichlangen Pleuelstangen 5 und 6The two oppositely rotating crankshafts 1 and 2 are connected to each other via the two gears 3 and 4 Intervention. The two connecting rods 5 and 6 of the same length

:..= V*:»:-»: 3322 UO: .. = V * : » : -» : 3322 UO

sind durch die beiden Kolbenbolzen 7 und 8 mit dem Hubkolben 9 verbunden, der mittels Kolbenringen 10 und 11 und dem ölabstreifring 12 gegen den Zylinder abgedichtet ist. An den Kurbelwellen 1 und 2 angebrachte Gegengewichte 14 und 15 gleichen die Massenkräfte von Pleuelstangen 5 und 6 sowie von Hubkolben weitgehend aus. Der Aufbau des Zylinderkopfes 16 ist konventionell.are connected to the reciprocating piston 9 by the two piston pins 7 and 8, which piston rings 10 and 11 and the oil control ring 12 against the cylinder is sealed. Counterweights 14 and 15 attached to crankshafts 1 and 2 equal the inertia forces of connecting rods 5 and 6 and of reciprocating pistons to a large extent. The structure of the cylinder head 16 is conventional.
