Die Erfindung betrifft eine Hubkolben-Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a reciprocating internal combustion engine according to the preamble of claim 1
Eine
derartige Hubkolben-Brennkraftmaschine ist aus der
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Kolben-Brennkraftmaschine anzugeben, die bei kompakten Abmessungen und hoher Laufruhe eine hohe spezifische Leistung ermöglicht.task the present invention is to provide a generic reciprocating internal combustion engine, the compact dimensions and smooth running a high specific Performance possible.
Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Patentanspruchs 1 dadurch gelöst, daß die Kurbelzapfen der jeweiligen Kurbelwelle eine gemeinsame Achse aufweisen, die parallel zur Drehachse der zugeordneten Kurbelwelle verläuft.These Task will be according to the characterizing Part of claim 1, characterized in that the crank pin of the respective Crankshaft have a common axis which is parallel to the axis of rotation the associated crankshaft runs.
Durch diese besondere Bauweise einer Hubkolben-Brennkraftmaschine wird ein kompakter Aufbau mit geringen Einbauabmessungen erzielt. Die Reihenmotor-Bauweise mit gleichlaufenden Kolben und der Doppel-Kurbelwellen-Anordnung sorgt für einen wirksamen Ausgleich der Massenkräfte erster Ordnung und somit für einen ruhigen Motorlauf.By This particular design of a reciprocating internal combustion engine is achieved a compact design with small installation dimensions. The in-line engine design with concurrent piston and double crankshaft arrangement takes care of an effective balance of the first order inertial forces and thus for one quiet engine running.
In einer bevorzugten Ausbildungsform der erfindungsgemäßen Hubkolben-Brennkraftmaschine sind die Pleuel am jeweiligen Kolben derart gelagert, daß die jeweiligen Lager in Bezug auf die parallel zu den Achsen der Kurbelwellen verlaufende Zylinder-Mittelebene seitlich versetzt sind. Diese Ausgestaltung sorgt dafür, daß die Kolben-Kippkräfte noch weiter reduziert werden und so eine noch höhere Laufruhe erzielt wird. Auch kann durch diese Ausgestaltung die Höhe des Kolbens und damit dessen Masse sehr stark reduziert werden, so daß Kolben aus temperaturfesterem, wenn auch schwererem Material gewählt werden können, wodurch wiederum die Verbrennungstemperatur und damit die spezifische Leistung des Motors erhöht werden können.In a preferred embodiment of the reciprocating internal combustion engine according to the invention the connecting rods are mounted on the respective piston such that the respective Bearing in relation to the parallel to the axes of the crankshaft running Cylinder middle plane are offset laterally. This embodiment makes sure that the Piston tilting forces still be further reduced and thus an even smoother running is achieved. Also, by this configuration, the height of the piston and thus its mass be greatly reduced, so that pistons from temperature-resistant, although heavier material can be chosen, thereby again the combustion temperature and thus the specific power of the engine increased can be.
In einer weiteren vorteilhaften Ausführungsform ist im Bereich der axialen, stirnseitigen Enden der Kurbelwellen jeweils ein Kurbelzapfen vorgesehen und die Kurbelwellen sind jeweils an beiden axialen Enden als Stirnkurbelwellen ausgebildet, wobei in Axialrichtung zwischen den Kurbelzapfen zumindest ein Lagerabschnitt auf der jeweiligen Kurbelwelle gebildet ist. Diese Ausgestaltung ermöglicht einen sehr kompakten Aufbau des Motors.In a further advantageous embodiment is in the field of axial, front ends of the crankshafts each have a crank pin provided and the crankshafts are respectively at both axial ends designed as front crankshafts, wherein in the axial direction between the crank pin at least one bearing portion on the respective Crankshaft is formed. This embodiment allows a very compact construction of the engine.
Weiter vorzugsweise ist zumindest eine der Kurbelwellen im Bereich zwischen den stirnseitigen Kurbelzapfen mit Antriebskraft-Übertragungselementen zum Antrieb von Steuereinrichtungen und/oder von Hilfseinrichtungen versehen. In dieser Ausführungsform dient der Zwischenraum zwischen den stirnseitigen Kurbelzapfen nicht nur zur Lagerung der Kurbelwelle, sondern in ihm sind auch Antriebskraft-Übertragungselemente vorgesehen, die bei herkömmlichen Motoren an der Kurbelwelle außerhalb des Kurbeltriebs angebracht sind. Derartige Antriebskraft-Übertragungselemente können beispielsweise zum Antrieb von Ventilsteuerungen, beispielsweise Nockenwellen, oder zum Antrieb von Hilfseinrichtungen, wie einer Ölpumpe oder einer Hydraulikpumpe oder einem Kompressor dienen.Further Preferably, at least one of the crankshafts is in the range between the end crank pin with driving force transmission elements for driving control devices and / or auxiliary equipment Mistake. In this embodiment does not serve the space between the end crank pin only for the storage of the crankshaft, but in it are also driving force transmission elements provided in the conventional Engines on the crankshaft outside the crank mechanism are mounted. Such driving force transmission elements can For example, to drive valve controls, for example Camshafts, or to drive auxiliary equipment, such as an oil pump or Serve a hydraulic pump or a compressor.
Vorzugsweise stehen die Kurbelwellen über Zahnräder mit einander in Eingriff. Eine derartige Kopplung der Kurbelwellen dient nicht nur der Synchronisation, sondern überträgt außerdem die an den jeweiligen Kurbelwellen anliegenden Arbeits-Drehmomente, welche beispielsweise an einem Zahnrad einer Kurbelwelle durch ein weiteres Abtriebszahnrad über eine Abtriebswelle abgeführt werden können.Preferably are the crankshafts on gears with engaged each other. Such a coupling of the crankshafts is used not only the synchronization, but also transmits the to the respective Crankshaft applied working torques, which, for example on a gear of a crankshaft through a further driven gear via a Output shaft removed can be.
Bei einer bevorzugten Ausführungsform weist die Hubkolben-Brennkraftmaschine zwei Zylinder auf. Diese Ausführungsform gestattet einen besonders kompakten Aufbau einer erfindungsgemäßen Hubkolben-Brennkraftmaschine mit hoher Laufruhe und hoher spezifischer Leistung.at a preferred embodiment the reciprocating internal combustion engine two cylinders. This embodiment allows a particularly compact design of a reciprocating internal combustion engine according to the invention with high smoothness and high specific power.
Vorzugsweise ist die Hubkolben-Brennkraftmaschine als Dieselmotor ausgebildet.Preferably the reciprocating internal combustion engine is designed as a diesel engine.
Bevorzugt wird weiterhin, wenn die Hubkolben-Brennkraftmaschine nach dem Viertaktverfahren arbeitet.Prefers will continue when the reciprocating internal combustion engine operates on the four-stroke process.
