Abstract

Die Erfindung betrifft eine längenverstellbare Pleuelstange für einen Verbrennungsmotor mit einem ersten und zweiten Pleuelteil, die mit mindestens einer Zylinder-Kolben-Einheit relativ zueinander verstellbar sind, wobei die Zylinder-Kolben-Einheit eine Zylinderbohrung, einen darin längs bewegbar angeordneten Verstellkolben, eine Kolbenstange und mindestens einen in der Zylinderbohrung vorgesehenen ersten Druckraum zur Aufnahme von Motoröl, der einseitig von dem bewegbaren Verstellkolben begrenzt ist, aufweist. Erfindungsgemäß umfasst die Zylinder- Kolben-Einheit eine erste und eine zweite Schnittstelle, die Kolbenstange ist integral mit dem Verstellkolben ausgebildet und über die erste Schnittstelle der Zylinder-Kolben-Einheit mit dem ersten Pleuelteil verbunden, die Zylinderbohrung weist einen integralen oberen Anschlag für den Verstellkolben auf und die Zylinderbohrung ist über die zweite Schnittstelle der Zylinder-Kolben- Einheit mit dem zweiten Pleuelteil verbunden, wobei die erste Schnittstelle der Zylinder-Kolben- Einheit eine rein mechanische und die zweite Schnittstelle eine mechanische und eine hydraulische Schnittstelle ist. Ferner betrifft die Erfindung Montageverfahren und die Verwendung einer solchen Pleuelstange in einem Verbrennungsmotor und einen Verbrennungsmotor.The invention relates to a length-adjustable connecting rod for an internal combustion engine having a first and second connecting rod, which are adjustable relative to each other with at least one cylinder-piston unit, wherein the cylinder-piston unit, a cylinder bore, a longitudinally movably arranged adjusting piston, a piston rod and at least one provided in the cylinder bore first pressure chamber for receiving engine oil, which is bounded on one side by the movable adjusting piston has. According to the invention, the cylinder-piston unit comprises a first and a second interface, the piston rod is formed integrally with the adjusting piston and connected via the first interface of the cylinder-piston unit with the first connecting rod, the cylinder bore has an integral upper stop for the adjusting piston on and the cylinder bore is connected via the second interface of the cylinder-piston unit with the second connecting rod part, wherein the first interface of the cylinder-piston unit is a purely mechanical and the second interface is a mechanical and a hydraulic interface. Furthermore, the invention relates to assembly methods and the use of such a connecting rod in an internal combustion engine and an internal combustion engine.
