Description

Viertaktbrennkraftmaschine Die Erfindung betrifft eine Viertaktbrennkraftmaschine mit vier an den Enden eines H-förmigen Verbindungsgliedes befestigten Kolben. Erfindungsgemäß ist das H-förmige Verbindungsglied in der Verlängerung des an die gemeinsame Pleuelstange angelenkten Querbolzens an gegenüberliegenden Stellen mittels Gleitschuhen an der Zylinderwand abgestützt. Diese Abstützung bewirkt eine von Querbeanspruchungen freie Führung des Verbindungsgliedes und daher eine günstige Aufnahme des Druckes in den Lagern der Pleuelstange. Sie gestattet Verwendung sehr kurzer Kolben und ermöglicht außerdem Schmierung zweier in der Hubrichtung gegenüberliegender Zylinder von gemeinsamen Schmiermittelzuführungen aus, die in der Gehäusewand mitten zwischen den Zylindern liegen. Das Öl wird von den Gleitschuhen weiterbefördert. Die Druckaufnahme in den Lagern der Pleuelstange wird noch weiter verbessert, wenn die gemeinsamen Kolbenstangen für _ die in der Hubrichtung gegenüberliegenden Kolben gegeneinander gekrümmt sind. Die Krümmung schafft außerdem Raum für die Anbringung der Gleitschuhe an dem H-förmigen Verbindungsglied. Zweckmäßig werden die Gleitschuhe an dem Pleuelbolzen angebracht. Das H-förmige Verbindungsglied kann aus Einzelteilen zusammengesetzt sein oder aus einem Stück bestehen.Four-stroke internal combustion engine The invention relates to a four-stroke internal combustion engine with four pistons attached to the ends of an H-shaped connecting link. According to the invention is the H-shaped connecting link in the extension of the common connecting rod hinged cross bolt at opposite points by means of sliding shoes on the Cylinder wall supported. This support results in one that is free of transverse loads Guide the connecting link and therefore a favorable absorption of the pressure in the Storage of the connecting rod. It allows the use of very short pistons and enables in addition, lubrication of two cylinders opposite one another in the stroke direction from common ones Lubricant feeds in the housing wall in the middle between the cylinders lie. The oil is carried on by the sliding shoes. The pressure absorption in the Bearing the connecting rod is further improved when the piston rods are common for _ the pistons opposite in the stroke direction are curved towards one another. The curvature also creates space for the sliding shoes to be attached to the H-shaped one Connecting link. The sliding shoes are expediently attached to the connecting rod bolt. The H-shaped connecting link can be assembled from individual parts or from consist of one piece.

Die Zeichnungen zeigen ein Beispiel für die Ausführung der Erfindung, und zwar in Fig. i einen Schnitt durch sämtliche vier Zylinder einer Viertaktbrennkraftmaschine, in Fig. 2 einen Schnitt nach Linie A-A der Fig. i.The drawings show an example of the implementation of the invention, namely in Fig. i a section through all four cylinders of a four-stroke internal combustion engine, in Fig. 2 a section along line A-A of Fig. i.

Die vier Kolben r, 2, 3, 4 sind an den Schenkeln ca eines H-förmigen Verbindungsgliedes befestigt. Das Verbindungsglied besteht aus mehreren miteinander verschraubten Einzelteilen. Die Pleuelstange c ist an dem den Querstab bildenden Pleuelbolzen b gelagert. Auf :diesem Bolzen sind an beiden über die Kolbenstangen herausragenden Enden Gleitschuhe d aufgesetzt, die an der Zylinderwand gleiten. Die oberen und unteren Zylinder werden von gemeinsamen mittleren Schmiermittelzuführungen e aus geschmiert. Das durch die Zuführungen e in die Zylinder eintretende öl wird den Kolben von den Gleitschuhen d bei der Bewegung zugeführt. Die Gleitschuhe sorgen dabei auch für Verteilung des Öls in der Zylinderumfangsrichtung.The four pistons r, 2, 3, 4 are approximately H-shaped on the legs Link attached. The connecting link consists of several with each other screwed individual parts. The connecting rod c is on the one forming the cross bar Connecting rod pin b supported. On: These bolts are on both of the piston rods protruding ends of sliding shoes placed d that slide on the cylinder wall. The upper and lower cylinders are shared by central lubricant feeds e lubricated out. The oil entering the cylinders through the feeds e becomes fed to the piston by the sliding shoes d during the movement. The sliding shoes take care of it also for the distribution of the oil in the circumferential direction of the cylinder.

Die Gleitschuhe gewähren eine günstige Aufnahme der Explosions- und Kompressionsdrücke, die in der Regel einseitig an dem Verbindungsglied angreifen. Sie ermöglichen außerdem Einbau sehr kurzer, leichter Kolben, daher Verminderung der Reibung, Verminderung des Gewichts, Verminderung des Ölverbrauchs und Steigerung der Leistung.The sliding shoes allow a favorable absorption of the explosion and Compression pressures that act on one side of the connecting link as a rule. They also allow the installation of very short, light pistons, hence a reduction of friction, reduction in weight, reduction in oil consumption and increase performance.

Bei Vermehrung der Zylinder um je vier Einheiten kann die Maschine in V-Form gebaut werden. _If the cylinders are increased by four units each, the machine can be built in V-shape. _
