Abstract

The two-stroke radial internal combustion engine or compressor according to the invention permits a simple construction of the crankshaft and the crankcase. Due to the fact that it is controlled by the interaction of piston and cylinder, series-manufactured parts can be used for this purpose. The individual crank spaces can be sealed off from one another by simple means.

Description

Die Erfindung betrifft einen Zweitaktverbrennungs­ motor oder Zweitaktverdichter in Sternbauweise, die es ermög­ licht einen Sternmotor oder Sternverdichter so zu bauen, daß der Einzelzylinder in der ihm eigenen Art mit Schlitzsteuerung betrie­ ben werden kann.The invention relates to a two-stroke combustion motor or two-stroke compressor in star design, which made it possible light to build a radial engine or radial compressor so that the Single cylinder operated in its own way with slot control can be used.

Das heißt jedem Zylinder ist sein kurbelgehäuseseitiger Vorverdich­ tungsraum zugeordnet. Die Steuerung erfolgt in bekannter Weise durch den Kolben in Verbindung mit Einlaß- und Auslaßschlitzen und Über­ strömkanälen im Zylinder.That means each cylinder is its pre-compression on the crankcase side assigned to the room. The control is carried out in a known manner the piston in connection with inlet and outlet slots and over flow channels in the cylinder.

Nach dem Stand der Technik sind viele Lösungen für einen Zwei­ takt-Sternmotor vorgestellt worden.According to the state of the art, there are many solutions for two clock radial engine has been introduced.

Die als "König"-Motor bekannte 3- und 4-Zylinder-Sternmotore sind insofern echte Zweitaktmotore, weil jedem Zylinder sein ei­ gener Vorverdichtungsraum zugeordnet ist. Die Steuerung wird aber durch eine Kombination von Steuerscheiben, die mit der Kurbelwel­ le drehen und Schlitzsteuerung im Zylinder herbeigeführt.The 3- and 4-cylinder radial engines known as the "König" engine are real two-stroke engines because each cylinder has its own egg gener pre-compression space is assigned. The control is through a combination of control disks that are connected to the crankshaft Turn the le and control the slot in the cylinder.

Ein anderer Zweitakt-Sternmotor kann nicht als echter Zweitakt- Motor bezeichnet werden. Bei diesem Motor wird nicht jedem Zylin­ der sein eigener Vorverdichtungsraum zugeordnet. Vielmehr hat der Kurbelraum ständig Verbindung zu jedem Zylinder. Da dadurch keine Vorverdichtung entsteht, wird der für das Überströmen und Spülen nötige Druck durch einen gesonderten Verdichter erzeugt, der den Kurbelraum mit Gemisch versorgt.Another two-stroke radial engine cannot be a real two-stroke Engine. Not every cylin will work with this engine which assigned its own precompression room. Rather, the Crankcase constantly connecting to each cylinder. Because it doesn't Pre-compression occurs, that for overflow and flushing necessary pressure generated by a separate compressor that the Crankcase supplied with mixture.

Auf der Zeichnung ist die erfindungsgemäße Konstruktion eines 4- Zylindermotores gezeigt.In the drawing, the construction of a 4- Cylinder engine shown.

Das Kurbelgehäuse (1) hat eine zylindrische Bohrung und ist (nicht dargestellt) an beiden Seiten durch Lagerflansche für die Kurbel­ welle (2) abgeschlossen. Das Kurbelgehäuse hat die Auskreisungen für die Zylinderfüße (3). Zweckmäßig ist in die Bohrung des Kur­ belgehäuses ein Rohr (4) eingesteckt, daß die erfindungsgemäßen Schlitze (5) in Umfangsrichtung hat. Diese Schlitze verbinden nur den jeweiligen Kurbelraum mit dem Zylinder. Sie brauchen nur so groß sein, daß die Freigängigkeit der Pleuel gegeben ist. The crankcase ( 1 ) has a cylindrical bore and is (not shown) on both sides by bearing flanges for the crank shaft ( 2 ). The crankcase has the cutouts for the cylinder feet ( 3 ). Appropriately, a tube ( 4 ) is inserted into the bore of the cure belgehäuses that the slots ( 5 ) according to the invention has in the circumferential direction. These slots only connect the crankcase to the cylinder. They only need to be large enough to allow the connecting rods to move freely.

Die Kurbelwelle (2) setzt sich aus zwei Teilen zusammen. Der rechte Teil besteht aus der Abtriebswelle, der Kurbelwange und dem Kurbelzapfen.The crankshaft ( 2 ) consists of two parts. The right part consists of the output shaft, the crank arm and the crank pin.

Der linke Teil hat eine Welle für den Antrieb von Aggregaten (z. B. Lichtmaschine) und eine durchbohrte Kurbelwange. Die Kur­ belwelle ist deshalb geteilt, um den Zusammenbau mit den Pleueln (6) und den erfindungsgemäßen abdichtenden Scheiben (7) zu er­ möglichen. Selbstverständlich könnte auch das Kurbelgehäuse und das Innenrohr so unterteilt sein, daß ein axialer Zusammenbau möglich wird. In so einem Fall könnte die Kurbelwelle z. B. ver­ preßt sein.The left part has a shaft for driving units (e.g. alternator) and a pierced crank arm. The cure belwelle is therefore divided to enable assembly with the connecting rods ( 6 ) and the sealing washers ( 7 ) according to the invention. Of course, the crankcase and the inner tube could also be divided so that an axial assembly is possible. In such a case, the crankshaft could e.g. B. be pressed ver.

Beim Zusammenbau im vorliegenden Fall werden auf dem Kurbelzapfen die Scheiben (7) und die Innenringe (8) der Pleuellager durch an­ ziehen der Mutter (9) fest miteinander verbunden.When assembling in the present case, the washers ( 7 ) and the inner rings ( 8 ) of the connecting rod bearings are firmly connected to one another by tightening the nut ( 9 ) on the crank pin.

Eine Kurbelwellenverzahnung ( 10) des Kurbelzapfens und der Kur­ belwange verhindert ein Verdrehen. Die Kurbelwelle ist links in einem Kugellager (11) und rechts in einem Zylinderrollenlager (127 gelagert. Mögliche weiter außen liegende Lager sind nicht darge­ stellt. An den Kurbelwangen und den abdichtenden Scheiben sind Auswuchtgewichte (13) angebracht.Crankshaft teeth ( 10 ) on the crank pin and the cure prevent twisting. The crankshaft is mounted on the left in a ball bearing ( 11 ) and on the right in a cylindrical roller bearing ( 12 7. Possible bearings located further out are not shown. Balancing weights ( 13 ) are attached to the crank cheeks and the sealing washers.

Im vorliegenden Beispiel ist der erfindungsgemäße Gegenstand an­ hand eines 4-Zylindermotors mit einem in der Kurbelhausbohrung befindlichen geschlitzten Rohr (4) erklärt. Der Erfindungsgegen­ stand kann aber auch auf 3-Zylindermotore und auf mehr als 4- Zylindermotore angewendet werden. Auch kann auf das hier beschrie­ bene geschlitzte Rohr verzichtet werden, wenn das Kurbelgehäuse selbst entsprechend bearbeitet wird.In the present example, the object according to the invention is explained using a 4-cylinder engine with a slotted tube ( 4 ) located in the crankcase bore. The subject of the invention but can also be applied to 3-cylinder engines and more than 4-cylinder engines. It is also possible to do without the slotted tube described here if the crankcase itself is machined accordingly.
