Description
Die vorliegende Erfindung betrifft einen Krümmer zur Montage an einem Aus- oder Einlass einer Brennkraftmaschine. Derartige Krümmer dienen zum Zuführen von Luft-Kraftstoffgemisch bzw. zum Ableiten der bei der Verbrennung des Gemisches entstehenden Abgase. Die Krümmer, insbesondere die am Auslass montierten, sind erheblichen thermischen Belastungen ausgesetzt; sie können im Laufe des Betriebs der Brennkraftmaschine Temperaturen in der Größenordnung von 1000°C erreichen.The The present invention relates to a manifold for mounting on an or inlet of an internal combustion engine. Such manifolds serve for feeding of air-fuel mixture or for the derivation of the combustion the mixture resulting exhaust gases. The manifolds, especially those at the outlet mounted, are exposed to significant thermal loads; you can during the operation of the engine temperatures in the Magnitude from 1000 ° C to reach.
Derartige Krümmer wurden lange Zeit als Gussteile gefertigt. In den letzten Jahren hat es zunehmende Bemühungen gegeben, derartige Krümmer mit Hilfe von Fügetechniken zu realisieren. Diese Techniken erlauben es prinzipiell, vergleichsweise geringe Wandstärken für den an der Brennkraftmaschine zu montierenden Flansch des Krümmers in der Größenordnung von 3 oder sogar nur 1,5 mm zu verwenden, doch haben sich mit so dünnen Flanschflächen gefertigte Krümmer bislang als für den Feldeinsatz nur beschränkt geeignet erwiesen. Die hohen thermischen Belastungen führen zu Deformationen der dünnwandigen Flansche, in deren Folge es an der Verbindung vom Flansch zum Krümmerrohr zu Undichtigkeiten und anderen Dauerhaltbarkeitsproblemen kommen kann.such elbow were made for a long time as castings. In recent years it has increasing efforts given, such manifolds with the help of joining techniques to realize. These techniques allow it in principle, comparatively small wall thickness for the to be mounted on the internal combustion engine flange of the manifold in the Magnitude of 3 or even just 1.5mm, but have to deal with so thin flange manufactured manifolds so far as for the field use only limited proved suitable. The high thermal loads lead to Deformations of thin-walled Flanges, as a result of which at the connection from the flange to the manifold pipe come to leaks and other durability issues can.

Krümmer
nach dem Oberbegriff des Anspruchs 1 ist aus
Aufgabe der vorliegenden Erfindung ist, einen in Fügetechnik aus dünnwandigem Material realisierbaren Krümmer anzugeben, der eine für den Feldeinsatz ausreichende Dauerbelastbarkeit aufweist.task The present invention is a in joining of thin-walled Material realizable manifold specify one for the field use has sufficient continuous load capacity.
Eine weitere Aufgabe ist, ein Verfahren zur Herstellung eines solchen Krümmers anzugeben.A Another object is a method for producing such elbow specify.
Die Aufgabe wird zum einen gelöst durch einen Krümmer mit den Merkmalen des Anspruchs 1 und zum anderen durch ein Herstellungsverfahren mit den Merkmalen des Anspruchs 9. Um die gewünschte Stabilität zu erreichen, genügt für die Hülse eine geringere Wandstärke als für den Flansch. Insbesondere kann die Wandstärke des Flansches 4 mm oder weniger, vorzugsweise ca. 3 mm, und die der Hülse 3 mm oder weniger, vorzugsweise ca. 2 mm, betragen.The Task is solved on the one hand through a manifold with the features of claim 1 and the other by a manufacturing method with the features of claim 9. In order to achieve the desired stability, enough for the Sleeve one lower wall thickness as for the flange. In particular, the wall thickness of the flange 4 mm or less, preferably about 3 mm, and the sleeve 3 mm or less, preferably about 2 mm, amount.
Einer besonders bevorzugten Ausgestaltung zufolge weist die Hülse wenigstens zwei Abschnitte auf, darunter einen dem Flansch benachbarten, mit dem Rohr formschlüssigen Abschnitt, der das Rohr in seiner Ausrichtung in Bezug auf den Flansch fixiert, und einen zu einem freien Ende der Hülse hin divergenten Abschnitt, der es dem Rohr ermöglicht, Hebelmomenten, die auf den Krümmer einwirken, ein Stück weit nachzugeben, und der das Rohr dabei abstützt. Der Öffnungswinkel des divergenten Abschnitts liegt zweckmäßigerweise zwischen 2 und 10°, bevorzugt bei ca. 50°.one According to a particularly preferred embodiment, the sleeve has at least two sections, including one adjacent to the flange, with the Tube form-fitting Section that holds the tube in its orientation with respect to the flange fixed, and a section diverging toward a free end of the sleeve, which allows the pipe to Leverage moments on the manifold act, a piece to give way, and the pipe supports it. The opening angle of the divergent Section is conveniently located between 2 and 10 °, preferably at about 50 °.
Vorteilhaft ist auch, dass der divergente Abschnitt in einem Schnitt senkrecht zur Ebene des Flansches eine Krümmung aufweist. Dies ermöglicht es dem Rohr, wenn es sich unter einem Hebelmoment verformt, sich über eine mit zunehmendem Hebelmoment anwachsende Länge an den divergenten Abschnitt anzuschmiegen, so dass die aus dem Hebelmoment resultierende Beanspruchung des Rohrs sich über die gesamte abgestützte Länge verteilt. Ein Krümmungsradius von 3 bis 10 mm ist hier für angemessenAdvantageous is also that the divergent section in a section perpendicular to the plane of the flange a curvature having. This allows it the tube, when it deforms under a lever moment, over a increasing length with increasing lever moment to the divergent section snug so that the stress resulting from the moment of the lever the pipe is over the entire supported Length distributed. A radius of curvature from 3 to 10 mm is here for reasonable
