Abstract
Die vorliegende Erfindung betrifft eine Ausgleichswelle für eine Verbrennungskraftmaschine eines Kraftfahrzeuges, bestehend aus einem Ausgleichsgewicht (AGW) innerhalb eines Rohres (R), wobei der Mantel des Rohres (R) der Außenform des Ausgleichsgewichtes (AGW) angepasst dieses umgebend gestaltet ist..The present invention relates to a balance shaft for an internal combustion engine of a motor vehicle, consisting of a balance weight (AGW) within a tube (R), the jacket of the tube (R) being adapted to the outer shape of the balance weight (AGW) to surround it.
Description
Die vorliegende Erfindung betrifft eine Ausgleichswelle für eine Verbrennungskraftmaschine der Art von Anspruch 1. The present invention relates to a balance shaft for an internal combustion engine of the type of
In modernen Verbrennungskraftmaschinen werden Ausgleichswellen zur Kompensation von motorischen Schwingungen eingesetzt. Diese Schwingungen sind als freie Massen- und/oder Massenmomente bekannt. Eine Kompensation dieser Schwingungen trägt zur Verbesserung der Laufruhe und des akustischen Verhaltens der Verbrennungskraftmaschine bei. In modern internal combustion engines, balance shafts are used to compensate for engine vibrations. These vibrations are known as free mass and / or mass moments. A compensation of these vibrations contributes to the improvement of smoothness and the acoustic behavior of the internal combustion engine.
Ausgleichswellen werden meist als einstückige Teile gesenkgeschmiedet, gegossen, gesintert oder auch durch eine Kombination der genannten Verfahren hergestellt. Balancing shafts are usually forged as one-piece parts, cast, sintered or even produced by a combination of said methods.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Ausgleichswelle in gegenüber den bekannten Lösungen verbesserter Form zu schaffen. It is an object of the present invention to provide a balance shaft in relation to the known solutions improved form.
Die Lösung der vorstehend genannten Aufgabe erfolgt durch eine Ausgleichswelle mit den Merkmalen des Anspruchs 1. Weiterbildungen ergeben sich aus den Unteransprüchen. The solution of the above object is achieved by a balance shaft having the features of
Die erfindungsgemäße Ausgleichswelle besteht aus einem Ausgleichsgewicht, welches von einem Rohrblech anliegend umschlossen ist. Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Ausgleichswelle dadurch hergestellt, dass in ein rotationssymmetrisches Rohr als Ausgangsform ein Ausgleichsgewicht eingesetzt wird und das Rohr anschließend durch ein formgebendes Verfahren derart verformt wird, dass das Blech des Rohres im Wesentlichen vollständig an dem Ausgleichsgewicht anliegt. Als formgebende Verfahren kommen Pressen oder Hochdruckumformung (Hydroforming) zur Anwendung. The balance shaft according to the invention consists of a balance weight, which is enclosed by a tube sheet fitting. According to a preferred embodiment of the invention, the balancer shaft is produced by inserting a balancing weight into a rotationally symmetrical tube as the starting shape and subsequently deforming the tube by a shaping method such that the sheet of the tube substantially fully abuts the balancing weight. As forming processes, pressing or high pressure forming (hydroforming) are used.
Die Formgebung des Rohrmantels, des Bleches kann dergestalt sein, dass der Rohrmantel in Kontakt zu der Kontur des Ausgleichsgewichtes geformt wird. Auch kann vorgesehen sein, dass in bestimmten Bereichen ein Spalt zwischen Rohrmantel, dem Blech und dem Ausgleichsgewicht verbleibt. The shape of the pipe jacket, the sheet may be such that the pipe jacket is formed in contact with the contour of the balance weight. It can also be provided that in certain areas there remains a gap between pipe jacket, the sheet metal and the balance weight.
Eine Weiterbildung der Erfindung sieht vor, dass die Verformung des Rohrkörpers neben dem Einschluss, dem sich Anlegen des Rohrmantelmaterials an die Kontur des Ausgleichsgewichtes wenigstens einen strukturversteifenden Abschnitt, bspw. in Form einer Rippe, schafft. Dieser erstreckt sich vorzugsweise in Achsrichtung zwischen zwei Lagerstellen der Welle. A further development of the invention provides that the deformation of the tubular body in addition to the inclusion, the application of the pipe casing material to the contour of the balance weight at least one structurally stiffening portion, for example. In the form of a rib creates. This preferably extends in the axial direction between two bearing points of the shaft.
Die Erfindungsgemäß bevorzugt vorgesehenen Versteifungsstrukturen können als Rippen unter Bildung von Hohlräumen – gegenüber dem Körper des Ausgleichsgewichtes – gestaltet sein. Dadurch ergibt sich insbesondere ein Vorteil gegenüber den rohrförmigen Ausgleichswellen. Gegenüber dn rohrförmigen Ausgleichswellen mit eingesetzten Ausgleichs- bzw. Unwuchtgewichten ergibt sich ferner der Voerteil, das die Ausgleichs-, die Unwuchtmasse durch das verformte und anliegende Rohrblechmaterial fest gehalten wird und zusätzliche Befestigungsmaßnahmen nicht erforderlich sind. The stiffening structures preferably provided according to the invention can be designed as ribs with the formation of cavities - in relation to the body of the balance weight. This results in particular an advantage over the tubular balance shafts. Opposite the tubular balance shafts with balancing or imbalance weights used also results in the Voerteil that the balance, the imbalance mass is held firmly by the deformed and adjacent tube sheet material and additional fastening measures are not required.
Eine bevorzugte Weiterbildung der Erfindung sieht die Verwendung eines Rohrmaterials vor, bei dem die Blechdicke, die Dicke des Mantelmaterials variiert. Insbesondere kann so eine Ausgleichswelle geschaffen werden, bei der die Manteldicke in Erstreckungsrichtung unterschiedlich ist. Auch kann ein Rohrmaterial verwendet werden, bei dem die Manteldicke in Umfangsrichtung variiert, also unterschiedlich ist. A preferred embodiment of the invention provides for the use of a tube material in which the sheet thickness, the thickness of the jacket material varies. In particular, such a balance shaft can be created, in which the jacket thickness is different in the direction of extent. Also, a pipe material can be used in which the jacket thickness varies in the circumferential direction, that is different.
Bei der erfindungsgemäßen Ausgleichswelle können mehrere Ausgleichsgewichte in Erstreckungsrichtung hintereinander eingebracht und von dem Rohrmaterial im Wesentlichen eingeschlossen werden. In the balancing shaft according to the invention, a plurality of balancing weights can be introduced one behind the other in the direction of extent and substantially enclosed by the tube material.
Nachfolgend wird eine Ausführungsform der Erfindung rein beispielhaft anhand der Figuren erläutert. Hereinafter, an embodiment of the invention will be explained purely by way of example with reference to FIGS.

Unter Aufbringung, Beaufschlagung des Innenraumes des Rohres R mit Wasser unter Druck, in Verbindung mit einer außen um das Rohr gelegten, geschlossenen Form (nicht dargestellt) lassen sich auch in dem nicht vom Ausgleichsgewicht AGW besetzten Raum Gestaltungen erzeugen. Insbesondere können so die zylindrischen Bereiche der Lagerstellen LS sowie die der Versteifung dienende Rippe, der Versteifungsbereich VBR geformt werden. Under application, pressurization of the interior of the tube R with water under pressure, in conjunction with an externally placed around the pipe, closed mold (not shown) can be in the not occupied by the balance weight AGW room designs generate. In particular, the cylindrical regions of the bearings LS and the stiffening rib, the stiffening region VBR can thus be formed.
