Abstract
Description
Die Erfindung betrifft Veränderungen an einer mit einem Energiespeicher ausgerüsteten Pleuelstange, die der Übertragung der Energie zwischen einem Kolben und einer Kurbelwelle eines Hubkolbenmotors dient, wobei die Pleuelstange zwei voneinander getrennte, dem Kolben und der Kurbelwelle zugeordnete Pleuelstangenteile aufweist.The The invention relates to changes to an energy storage device Equipped connecting rod, the transmission the energy between a piston and a crankshaft of a reciprocating engine serves, with the connecting rod two separate, the piston and the crank shaft associated connecting rod parts.

In beiden Fällen erstrecken sich die hydraulischen und mechanischen Bauteile über die gesamte Länge der Pleuelstange, sodass eine hohe Masse des integrierten Energiespeichers sich ebenfalls in einer hohen Masse der hin- und hergehenden Bauteile äussert, was letztlich zu einer relativen Trägheit und damit hohem Energieverbrauch des Hubkolbenmotors führt.In In both cases, the hydraulic and mechanical extend Components over the entire length of the connecting rod, so that a high mass of the integrated energy storage also in a high mass of reciprocating components, which ultimately leads to a relative inertia and thus higher Energy consumption of the reciprocating engine leads.
Aufgabe der Erfindung ist es deshalb, eine Anordnung zu entwickeln, bei der in einem Hubkolbenmotor die vom Kolben über die Pleuelstange aufgebrachte Energie in einer günstigen Stellung der Kurbelwelle in diese eingeleitet wird.task The invention is therefore to develop an arrangement in in a reciprocating engine that from the piston via the connecting rod applied energy in a favorable position of the crankshaft is initiated in this.
Die Aufgabe wird durch eine Anordnung mit den im Patentanspruch 1 genannten kennzeichnenden Merkmalen gelöst.The The object is achieved by an arrangement with the mentioned in claim 1 solved characterizing features.
Weitere vorteilhafte Ausführungen des Erfindungsgegenstandes ergeben sich aus den nachgeordneten Patentansprüchen.Further yield advantageous embodiments of the subject invention from the subordinate claims.
Mit der Verwirklichung der erfindungsgemäßen Lösung wird eine masse- und und schwingungsreduzierte Bauweise erreicht. Durch die Verschiebung der Schwerpunkte des Energiespeichers in Richtung des Kurbelzapfens werden die aus der Umwandlung einer kreisförmigen Bewegung in eine hin- und hergehende Bewegung und umgekehrt resultierenden Massenkräfte abgebaut. Daraus resultiert eine größere Laufruhe der Maschine, ein geringerer Kraftstoffverbrauch und eine Reduzierung des Bauteilverschleißes. Die Anordnung ist auch ohne wesentliche Änderungen in vorhandenen üblichen Hubkolbenmotoren nachrüstbar.With the realization of the solution according to the invention a mass and vibration reduced construction is achieved. By shifting the focus of the energy storage in the direction of the crankpin are made from the transformation of a circular Moving into a reciprocating motion and vice versa Massive forces dismantled. This results in a larger one Smooth running of the machine, lower fuel consumption and a Reduction of component wear. The arrangement is even without significant changes in existing usual Reciprocable piston engines can be retrofitted.
Die Erfindung soll im folgenden an einem Ausführungsbeispiel näher beschrieben werden.The Invention is intended below in an embodiment be described in more detail.
