Abstract
Description
Die Erfindung betrifft einen Abgasturbolader mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to an exhaust gas turbocharger with the features of the Preamble of claim 1.
Die
Erfindung geht von der deutschen Offenlegungsschrift
Durch die, an den Leitschaufeln anliegende Gaskraft, wird beim Betrieb der Brennkraftmaschine der Dorn einseitig stärker belastet, was zu einem erhöhten Verschleiß des Dornes führt.By the gas force applied to the vanes becomes operational the internal combustion engine of the mandrel loaded on one side more heavily, which leads to increased wear of the mandrel.
Aufgabe der vorliegenden Erfindung ist es, eine Maßnahme aufzuzeigen, mit der der Verschleiß des Dornes verringert wird.task the present invention is to show a measure with which the wear of the mandrel is reduced.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.These The object is achieved by the features in the characterizing part of the claim 1 solved.
Durch die erfindungsgemäße Ausgestaltung des Dornes wird die Kontaktpressung zwischen der Kulisse und dem Dorn verringert. Dies führt zu einem geringeren Verschleiß und somit zu einer längeren Lebensdauer des Abgasturboladers. Darüber hinaus führt die erfindungsgemäße Ausgestaltung zu einer geringeren Laufzeitveränderung der Regelbarkeit des Abgasturboladers (hierunter wird die Veränderung des Ansteuertastverhältnisses verstanden). Außerdem führt die erfindungsgemäße Ausgestaltung zu einem verbesserten Verhalten bezüglich der Verstellhysterese des Abgasturboladers über die Lebensdauer. Weiter kann die erfindungsgemäße Ausgestaltung für jede vorwiegend einseitig belastete mechanische Verbindung, die eine Bewegung durch die Übertragung von Kontaktflächen zweier Körper vollzieht, umgesetzt werden.By the inventive design of the mandrel the contact pressure between the link and the mandrel is reduced. This leads to less wear and tear thus to a longer life of the exhaust gas turbocharger. In addition, the inventive leads Design for a lower maturity change of Controllability of the turbocharger (this is the change the driving duty ratio understood). Furthermore leads to the embodiment according to the invention an improved behavior with respect to the adjustment hysteresis the exhaust gas turbocharger over the life. Next can the embodiment of the invention for each mechanical connection, which is predominantly loaded on one side, the a movement through the transfer of contact surfaces of two bodies, be implemented.
Die Ausgestaltungen gemäß der Patentansprüche 2 und 3 entsprechen zwei besonders bevorzugten Ausführungsvarianten.The Embodiments according to the claims 2 and 3 correspond to two particularly preferred embodiments.
Die Ausgestaltung gemäß Patentanspruch 4 entspricht ebenfalls zwei besonders bevorzugten Ausführungsvarianten.The Design according to claim 4 corresponds also two particularly preferred embodiments.
Im Folgenden ist die Erfindung anhand eines besonders bevorzugten Ausführungsbeispieles in vier Figuren näher erläutert.in the The following is the invention with reference to a particularly preferred embodiment explained in more detail in four figures.
Im Folgenden gelten in allen Figuren für gleiche Bauteile die gleichen Bezugsziffern.in the The following apply in all figures for the same components the same reference numbers.
