Abstract

A reciprocating piston engine in which the cylinders are installed opposed to one another has the opposite-acting connecting rods flexibly connected in a connecting rod head small end and by the movable connecting rod big end swing around the main bearing by an angle (alpha ) with regard to each other in different directions.

Description

Die Erfindung betrifft die Hubkolbenmaschinen.The Invention relates to reciprocating engines.

"Das Pleuel überträgt die auf dem translatorisch bewegten Kolben wirkende Gaskräfte und die oszilierenden Massenkräfte des Triebwerks auf den rotierenden Hubzapfen der Kurbelwelle. Daraus resultieren folgende Anforderungen an dieses Bauteil:

  • – geringe Masse, da ein Teil der Pleuelmasse den oszilierenden Triebswerkmassen zu rechnen ist
  • – ausreichende Gestaltfestigkeit insbesondere in Hinblick auf: – Formsteifigkeit des Pleuelkopfes und des Pleuelauges; unzulässige Ovalverformung beeinträchtigt hydrodynamischen Schmierfilm, und im Extremfall ist "Lagerklemmen" möglich – Knicksicherheit des Pleuelschafts – dauerfeste Pleuelschraubenverbindung; ausreichende Sicherheit gegen Klaffen in der Teilungsfuge des Pleuelkopfes
  • – ausreichende Dimensionierung der Lagerstellen unter Berücksichtigung der Tragfähigkeit der Lager."
(Eduard Köhler, Verbrennungsmotoren, Vieweg Verlag, Wiesbaden, 2002, Seite 41)"The connecting rod transmits the gas forces acting on the translationally moving piston and the oscillating mass forces of the engine to the rotating crankpin of the crankshaft, resulting in the following requirements for this component:
  • - Low mass, since a part of the connecting rod mass is the oscillating engine masses to be expected
  • - sufficient structural strength, in particular with regard to: - stiffness of the connecting rod and the connecting rod eye; impermissible oval deformation impairs hydrodynamic lubricating film, and in extreme cases, "bearing clamps" are possible - buckling resistance of the connecting rod shaft - durable connecting rod screw connection; adequate safety against gape in the pitch of the connecting rod
  • - adequate dimensioning of the bearings taking into account the bearing capacity of the bearings. "
(Eduard Köhler, internal combustion engines, Vieweg Verlag, Wiesbaden, 2002, page 41)

Bei mehren Hubkolbenmaschinen, besonders bei Rotationszylindermaschinen, gibt es Probleme mit der Pleuelkopfstellung an der Kurbelwelle, da die Zylinder gegeneinander angeordnet sind. Meistens sind die Pleuelköpfe nebeneinander vorgesehen und dabei werden entweder die Zylinder von der Zentralachse verschoben oder die Pleuel in der verbogenen Form angeordnet.at several reciprocating engines, especially in rotary cylinder engines, there are problems with the connecting rod head position on the crankshaft, because the cylinders are arranged against each other. Mostly they are connecting rods provided side by side and thereby either the cylinder moved from the central axis or the connecting rods in the bent Arranged form.

Der Erfindung liegt die Aufgabe zugrunde, die Gestaltung der achselangeordneten Pleuelstangen in einem Pleuelkopf zu gewährleisten.Of the Invention is based on the object, the design of the axle-mounted To ensure connecting rods in a connecting rod.

Die Erfindung ist anhang eines in den Zeichnungen dargestellten Ausführungsbeispiels beschrieben. Es zeigt:The The invention is the appended of an embodiment shown in the drawings described. It shows:

In der 1: werden alle Komponente der Pleuelverbindung dargestellt.In the 1 : all components of the connecting rod connection are shown.
