MehrzylinderbrennkraftmaschineMulti-cylinder internal combustion engine
D i e E r f i n d u n g g e h t a u s v o n e i n e rThe f i n d u n g e h t a u s v o n e i n e r
Mehrzylinderbrennkraftmaschine nach der Gattung des Hauptanspruchs . Derartige Mehrzylinderbrennkraftmaschinen sind mehrfach bekannt, wobei es in erster Linie darum geht, den Wirkungsgrad des Motors dadurch zu verbessern, daß beim Explosionshub die Kräfteübertragung auf die Kurbeln möglichst in einem Bereich und dadurch optimal erfolgt, indem der Winkel zwischen Kolbenachse und Pleuelstange möglichst gering ist, während der Saughub aufgrund der Bewegungslage der Pleuelstange zu der Zylinderachse bei also einem großen Winkel einen langsameren Ansog des Motors ermöglicht, wodurch auch ohne Aufladung eine günstige Füllung des Brennraums ermöglicht wird. In zweiter Linie bietet diese Konstruktion mit zwei Pleuelstangen pro Kolben bzw. Zylindereinheit und mit zwei Kurbeln einen ruhigeren Lauf der Maschine an, auch durch den besseren Massenausgleich von Kurbelwelle und Pleuelstange. Diese Verbesserung des Wirkungsgrads führt zu einem günstigeren Kraftstoffverbrauch und einem bes seren Drehmoment im Vergleich zu Brennkraftmaschinen mit nur einer Kolbenstange, allerdings auf Kosten eines zusätzlichen Aufwandes bei der Herstellung, nämlich der zweitenMulti-cylinder internal combustion engine according to the type of the main claim. Multi-cylinder internal combustion engines of this type are known several times, the primary aim being to improve the efficiency of the engine in that the force transfer to the cranks takes place in the explosion stroke as far as possible and therefore optimally by the angle between the piston axis and the connecting rod being as small as possible, while the suction stroke enables a slower suction of the engine due to the position of the connecting rod relative to the cylinder axis at a large angle, which enables the combustion chamber to be filled cheaply even without charging. Secondly, this design with two connecting rods per piston or cylinder unit and with two cranks offers a smoother running of the machine, also thanks to the better mass balance of the crankshaft and connecting rod. This improvement in efficiency leads to cheaper fuel consumption and a better torque compared to internal combustion engines with only one piston rod, but at the expense of an additional effort in production, namely the second
Pleuelstange und der zweiten Kurbel, die für den Abtrieb mit der ersten synchronisiert werden muß.Connecting rod and the second crank, which must be synchronized with the first for the output.
Bei einer bekannten Brennkraftmaschine (DE-OS 31 29 028) sind die Vorteile von zwei Pleuelstangen pro Kolben und zwei miteinander synchronisierten gegenläufigen Kurbelwellen beschrieben. Zwar können mit solchen Motoren Unwuchten, die quer zur Kolbenachse verlaufen vollständig ausgeglichen werden - nicht aber in Richtung Achse verlaufende Unwuchten. Dies führt zu Schwingungen, die sich naturgemäß auf das Fahrzeug übertragen, unabhängig davon, ob es sich um ein Straßenfahrzeug, ein Wasser- oder Luftfahrzeug handelt.In a known internal combustion engine (DE-OS 31 29 028), the advantages of two connecting rods per piston and two counter-rotating crankshafts synchronized with one another are described. Such motors can completely compensate for imbalances that run transverse to the piston axis - but not imbalances that run in the direction of the axis. This leads to vibrations that are naturally transferred to the vehicle, regardless of whether it is a road vehicle, a watercraft or an aircraft.
Es ist ein anderer Motor bekannt (EP-PS 0 187 930), bei dem vier Zylinder symmetrisch zueinander und boxerartig angeordnet sind und mit ihren Pleuelstangen auf eine Kurbelwelle wirken, wobei durch diese Anordnung ein Ausgleich der Schwingungen angestrebt ist. Da jedoch nur eine Kurbelwelle und pro Zylinder nur eine Pleuelstange vorgesehen ist, wirkt sich dieses als Unwucht aus, auch deshalb, weil die Arbeitshübe immer mit einem außerhalb der Zylinderachse liegenden und entsprechend der Drehbewegung der Kurbelwelle sich in der Winkellage ändernden Kraftlinie erfolgt, was sich in entsprechenden Betriebsschwingungen des Motors äußert.Another engine is known (EP-PS 0 187 930), in which four cylinders are arranged symmetrically to each other and box-like and act with their connecting rods on a crankshaft, this arrangement aiming to compensate for the vibrations. However, since there is only one crankshaft and only one connecting rod per cylinder, this has an unbalance effect, also because the working strokes always take place with a force line lying outside the cylinder axis and changing in the angular position in accordance with the rotational movement of the crankshaft, which occurs in corresponding operating vibrations of the engine.
Bei wieder einer anderen bekannten Brennkraftmaschine der gattungsgemäßen Art (JP 61 14431 ) wirken die Pleuelstangen und damit quasi die Kurbeln bei einem Boxermotor auf zwei zwischen den Zylindereinheiten angeordneten Zahnrädern, die ineinanderkämmen. Abgesehen davon, daß während des Betriebs, jedenfalls in der Darstellung der Schrift, die Kurbeln der einander abgewandten Zylindereinheiten, die an einem Zahnrad angreifen, in Konflikt miteinander kommen würden, sind die beim Drehen gegebenen Massen Beschleunigungen der Kurbel nicht ausgeglichen, obwohl sie in Bezug auf die Zahnräder symmetrisch angelenkt sind, da beim Rotieren nur in den Extremlagen, nämlich bei Kolbenhubbeginn und -ende ein Massenausgleich stattfinden kann, so daß auch hier, je nach Drehzahl, entsprechende Betriebsschwingungen des Motors vorhanden sind.In yet another known internal combustion engine of the generic type (JP 61 14431), the connecting rods and thus, as it were, the cranks in a boxer engine act on two gear wheels arranged between the cylinder units, which mesh with one another. Apart from the fact that during operation, at least in the representation of the writing, the cranks of the cylinder units facing away from one another, which act on a gearwheel, would come into conflict with one another, the mass accelerations of the crank given during turning are not balanced, although they are related are articulated symmetrically on the gears, since when rotating only in the extreme positions, namely at the beginning and end of the piston stroke, mass balancing can take place, so that here, depending on the speed, corresponding operating vibrations of the engine are present.
Die erfindung sgemäße Brennkraftmaschine mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Brennkraftmaschine nahezu schwingungsfrei arbeitet. Darüber hinaus ist durch die Kombination von zwei Zylindereinheiten mit jeweils pro Zylindereinheit zwei Abtriebsrädern bei der Übertragung des Linearhubes auf die Drehbewegung ein besonders günstiges Drehmoment und ein äußerst günstiger Kraftstoffverbrauch erzielbar. Besonders die Einsparungen beim Kraftstoffverbrauch amortisieren sehr schnell die zusätzlichen Kosten für das zweite Abtriebsrad sowie sonstige notwendige Zusatzteile in der Abtriebseinheit.The fiction, contemporary internal combustion engine with the characterizing features of the main claim has the advantage that the internal combustion engine works almost vibration-free. In addition, the combination of two cylinder units, each with Cylinder unit two driven wheels in the transmission of the linear stroke to the rotary movement, a particularly favorable torque and extremely favorable fuel consumption can be achieved. The savings in fuel consumption, in particular, quickly amortize the additional costs for the second driven wheel and other necessary additional parts in the driven unit.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist die Abtriebseinheit mit ineinanderkämmenden Zahnrädern ausgestattet, welche mit den Kurbeln verbunden sind. Statt Zahnrädern könnten natürlich auch Ketten-, Riemen- oder sonstige -triebe dienen, wobei dann in manchen Ausgestaltungen allerdings gewisse Vorteile für die Pleuelstangenpaare in bezug auf spiegelsymmetrische Kraftübertragung verloren gingen.According to an advantageous embodiment of the invention, the output unit is equipped with intermeshing gear wheels which are connected to the cranks. Instead of gears, chain, belt or other drives could of course also be used, although in some configurations certain advantages for the connecting rod pairs with respect to mirror-symmetrical power transmission were lost.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weisen die Abtriebsräder den gleichen Durchmesser auf und sind symmetrisch zueinander mit parallelen Drehachsen angeordnet.According to a further advantageous embodiment of the invention, the driven wheels have the same diameter and are arranged symmetrically to one another with parallel axes of rotation.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung greifen die Antriebsräder jeweils unmittelbar ineinander bzw jedes Abtriebsrad greift in zwei der anderen Abtriebsräder.According to a further advantageous embodiment of the invention, the drive wheels mesh directly with each other or each driven wheel engages in two of the other driven wheels.
Nach einer weiteren vorteilhaften Ausgestaltunge der Erfindung sind mehrere solch eine erste, zweite oder zusätzliche Zylindereinheit aufweisende, eine Arbeitsebene bildende Einheiten reihenartig zu einem Reihenmotor kombinierbar, wobei sie eine gemeinsame Abtriebswelle aufweisen.According to a further advantageous embodiment of the invention, a plurality of such units having a first, second or additional cylinder unit and forming a working plane can be combined in rows to form a series engine, wherein they have a common output shaft.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Zylindereinheiten boxerartig mit parallelen Achsen zueinander angeordnet. Hierdurch kann ein Boxerreihenmotor entstehen mit äußerst günstigem Drehmoment und weitgehender Freiheit von Schwingungen oder Vibrationen.According to a further advantageous embodiment of the invention, the cylinder units are arranged in a box-like manner with axes parallel to one another. This enables an in-line boxer engine arise with extremely favorable torque and extensive freedom from oscillations or vibrations.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind zusätzliche dritte oder mehr Zylindereinheiten in einer Arbeitsebene, die sternförmig zueinander angeordnet sind, vorhanden. Maßgebend für die Laufruhe sind jeweils zwei Abtriebräder pro Zylindereinheit.According to a further advantageous embodiment of the invention, there are additional third or more cylinder units in a working plane which are arranged in a star shape relative to one another. Two drive wheels per cylinder unit are decisive for smooth running.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Kolben scheibenförmig ausgebildet, mit einem Minimum an Führungsflächen zur Wand des Motorzylinders hin. Die seitlichen Führungskräfte können minimiert werden, da die resultierende Kraftlinie der beiden Pleuelstangen in die Achse des Kolbens fällt, wodurch Querkräfte und Kippkräfte des Kolbens entfallen. Bei Normalmotoren besteht ein nicht unerheblicher energiefressender Gleitbahndruck. Die Masse, und damit die Dicke des Kolbens, kann bei der Erfindung durch die für die Kühlung gemachten Vorgaben bestimmt werden. So kann nach einer diesbezüglichen Ausgestaltung der Erfindung der Kolben auch aus Keramik odgl. bestehen.According to a further advantageous embodiment of the invention, the piston is disc-shaped, with a minimum of guide surfaces towards the wall of the engine cylinder. Lateral executives can be minimized because the resulting line of force of the two connecting rods falls into the axis of the piston, eliminating the transverse and tipping forces of the piston. In normal engines there is a not inconsiderable energy-consuming slide pressure. The mass, and thus the thickness of the piston, can be determined in the invention by the specifications made for the cooling. According to a related embodiment of the invention, the piston can also be made of ceramic or the like. consist.

In der sehr vereinfacht dargestellten Zeichnung ist ein Boxermotor im Längsschnitt dargestellt, mit einem Gehäuse 1 und zwei einander abgewandten Motorzylindern 2, in denen jeweils ein Kolben 3 arbeitet, und wobei die Brennräume 4 durch Zylinderköpfe 5 verschlossen sind, in denen die Motorventile 6 gelagert sind.In the very simplified drawing, a boxer engine is shown in longitudinal section with a housing 1 and two mutually facing engine cylinders 2, in each of which a piston 3 operates, and the combustion chambers 4 are closed by cylinder heads 5, in which the engine valves 6 are mounted.
Erfindungsgemäß werden von jedem Kolben 3 zwei Pleuelstangen 7 angelenkt, die auf der dem Kolben 3 abgewandten Seite jeweils als Kurbel 8 wirken, so daß entsprechend der vier Pleuelstangen auch vier Kurbel vorhanden sind, mit jeweils zueinander entgegengesetzter Drehrichtung. Diese Kurbeln greifen an Zahnrädern 9 an, von denen jeweils benachbarte Zahnräder 9 ineinander kämmen.According to the invention, two connecting rods 7 are articulated from each piston 3, each of which acts as a crank 8 on the side facing away from the piston 3, so that four crank rods are also present corresponding to the four connecting rods, each with the opposite direction of rotation. These cranks engage gear wheels 9, of which adjacent gear wheels 9 mesh with one another.
Erfindungsgemäß wirken somit eine aus Motorzylinder 2, Kolben 3, Brennraum 4 und Zylinderkopf 5 bzw. Motorventil 6 wirkende erste Zylindereinheit 1 1 einerseits und eine entsprechend ausgestattete, aber um 180° gewendete, zweite Zylindereinheit 12 über jeweils zwei Pleuelstangen 7 auf jene vier Kurbelwellen, welche mit dem Gehäuse 1 , den Zahnrädern 9 und einer nicht dargestellten Abtriebswelle eine Abtriebseinheit 13 bilden. Aufgrund de s gu t erken n b are n M as s en- und Querkräfteau sgleichs arbeitet die ser Motor nahezu schwingungsfrei . Aufgrund eines guten mechanischen Wirkungsgrads ist auch der Kraftstoffverbrauch äußerst gering.According to the invention, a first cylinder unit 11 acting from the engine cylinder 2, piston 3, combustion chamber 4 and cylinder head 5 or engine valve 6, on the one hand, and a correspondingly equipped, but turned by 180 °, second cylinder unit 12 act on those four crankshafts via two connecting rods 7, which form an output unit 13 with the housing 1, the gears 9 and an output shaft, not shown. Due to the balancing of mass and transverse forces, this motor works almost vibration-free. Thanks to its good mechanical efficiency, fuel consumption is also extremely low.
