Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Befestigung eines Kraftstoff einspritzenden Injektors an einer Brennkraftmaschine, insbesondere am Zylinderblock einer Brennkraftmaschine, entsprechend dem Oberbegriff des Anspruchs 1.The The invention relates to a device for fixing a fuel injection injector on an internal combustion engine, in particular on the cylinder block of an internal combustion engine, according to the preamble of claim 1.
Für Kraftstoff einspritzende Injektoren, insbesondere für Injektoren zur Verwendung in Common-Rail-Systemen, werden gemäß dem Stand der Technik zur Befestigung am Zylinderblock der Brennkraftmaschine Pratzen verwendet. Diese Pratzen üben eine axiale Spannkraft auf den Injektor aus, so dass dieser in Richtung auf den Zylinderblock gedrückt wird.For fuel injector injectors, in particular for injectors for use in common-rail systems, according to the prior art Attachment to the cylinder block of the internal combustion engine claws used. Practice these claws an axial clamping force on the injector, so this in the direction pressed on the cylinder block becomes.
Die am Motor zu befestigenden Injektoren können bei relativ großer Länge einen vergleichsweise kleinen Durchmesser aufweisen. Ein Teil des Injektors ist im Zylinderblock der Brennkraftmaschine aufgenommen. Der sich daran anschließende Teil des Injektors liegt frei und ist, bedingt durch die bei Brennkraftmaschinen auftretenden Vibrationen, einer relativ hohen Schwingbelastung ausgesetzt.The On the engine to be fastened injectors can be a relatively large length have comparatively small diameter. Part of the injector is included in the cylinder block of the internal combustion engine. Which subsequent Part of the injector is free and is due to the internal combustion engines occurring vibrations, exposed to a relatively high vibration load.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der eingangs genannten Art so weiterzubilden, dass die mechanischen Belastungen des Injektors möglichst gering sind.task The present invention is a device of the initially educate so-called type so that the mechanical loads of the Injector as possible are low.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a device having the features of the claim 1 solved.
Vorteile der ErfindungAdvantages of invention
Durch die Ergänzung der axialen Spannkraft mit radialen Spannkräften kann der freiliegende Teile des Injektors nicht nur entlang einer Achse, sondern im Raum eingespannt werden. Durch die radial nach innen wirkenden Spannkräfte kann ein Verkippen des Injektors vermieden werden. Hierdurch wird die Schwingbelastung des Injektors verringert. Außerdem werden diejenigen Bauteile des Injektors geschont, die innerhalb des Injektors beweglich angeordnet sind und mit nur sehr kleinen Toleranzen behaftet sind.By the complement the axial clamping force with radial clamping forces, the exposed Parts of the injector not only along an axis, but in space be clamped. By the radially inward clamping forces can tilting of the injector can be avoided. As a result, the vibration load of the injector is reduced. Furthermore those components of the injector are spared within the injector are movably arranged and with only very small Tolerances are affected.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.advantageous Embodiments are specified in the subclaims.
Besonders vorteilhaft ist die Verwendung eines Spannadapters mit einer Kraftübertragungsfläche, die sowohl zur Längsachse des Injektors als auch zu einer zur Längsachse des Injektors im Wesentlichen senkrechten Ebene geneigt ist. Mit dieser Kraftübertragungsfläche können gleichzeitig axiale und radiale Spannkräfte erzeugt werden.Especially advantageous is the use of a clamping adapter with a power transmission surface, the both to the longitudinal axis the injector as well as to the longitudinal axis of the injector substantially vertical plane is inclined. With this power transmission surface can simultaneously axial and radial clamping forces be generated.
