Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Getriebegehäusen, insbesondere von Getriebegehäusen für PKW und NKW, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a process for the preparation of Transmission housings, in particular of gear housings for cars and commercial vehicles, according to the generic term of claim 1
Bei Getriebegehäusen für PKW und NKW ist eine hohe Festigkeit von besonderer Bedeutung. Üblicherweise werden nach dem Stand der Technik derartige Gehäuse im Druckgussverfahren hergestellt. Es ist jedoch bekannt, einzelne Getriebebauteile mittels Umformverfahren herzustellen. Die Vorteile der Umformverfahren, insbesondere der „Hydroforming"-Umformverfahren gegenüber klassischen Umformverfahren liegen in einer gleichmäßigen und hohen Festigkeit und Steifheit, optimiertem Gewicht sowie hoher Genauigkeit der auf diese Weise hergestellten Bauteile.at gear boxes for cars and commercial vehicles is a high strength of particular importance. Usually According to the prior art, such housings are produced by die-casting. It However, it is known, individual transmission components by forming manufacture. The advantages of the forming process, especially the "hydroforming" forming process across from classical forming processes lie in a uniform and high strength and stiffness, optimized weight and high Accuracy of the components produced in this way.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Getriebegehäusen, insbesondere von Getriebegehäusen für PKW und NKW anzugeben, durch dessen Durchführung die Festigkeit der Gehäuse signifikant erhöht wird. Des weiteren sollen größere Querschnitte ermöglicht und Toleranzen reduziert werden.Of the The present invention is based on the object, a method for the manufacture of gearboxes, in particular of transmission housings for cars and Indicate by carrying out the strength of the housing significantly is increased. Furthermore, larger cross sections allows and tolerances are reduced.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.
Demnach wird vorgeschlagen, Getriebegehäuse für PKW und NKW durch ein „Hydroforming"-Umformverfahren herzustellen. Im Rahmen einer vorteilhaften Ausführungsform ist vorgesehen, stranggepresste Profile über ein „Hydroforming"-Umformverfahren zum Gehäuse umzuformen.Therefore it is proposed gearbox for cars and commercial vehicles through a "hydroforming" forming process manufacture. In the context of an advantageous embodiment is provided, extruded Profiles over a "hydroforming" forming process to the housing reshape.
Des weiteren kann gemäß der Erfindung vorgesehen sein, dass an der Außenkontur des Gehäuses Nebenfunktionsflächen und/oder -löcher erzeugt werden.Of another can according to the invention be provided that on the outer contour of the housing In addition to functional surfaces and / or holes be generated.
Es ist auch möglich, dass die Oberflächenstruktur eines durch das erfindungsgemäße Verfahren herzustellenden Gehäuses definiert verändert wird; beispielsweise kann über eine als „Golfballoberfläche" ausgebildete Gehäuseoberfläche eine Minderung der Geräusche erzielt werden.It is possible, too, that the surface texture one by the method according to the invention to be produced housing is changed defined; for example can over a designed as a "golf ball surface" housing surface a Reduction of noise be achieved.
Durch die erfindungsgemäße Konzeption können die Querschnitte mindestens 100 % aufgeweitet werden. In vorteilhafter Weise wird bei einer gleichzeitig erzielbaren Reduzierung der Toleranzen eine Festigkeitserhöhung um ca. 50 % erzielt.By the conception according to the invention can be Cross sections at least 100% be widened. In an advantageous manner Way is a simultaneously achievable reduction of tolerances increase in strength achieved by about 50%.
