Abstract
Die Erfindung betrifft eine Welle, insbesondere für einen Motor eines Kraftfahrzeugs, mit zumindest einem zylindrisch ausgebildeten Lagerbereich (10), welcher sich entlang einer Drehachse (A) der Welle erstreckt und gegenüber einer kreiszylinderförmigen Umhüllungsfläche (12) wenigstens eine in Bezug auf die Drehachse (A) axiale Ausnehmung (14) umfasst, wobei der Lagerbreich (10) zusätzlich wenigstens eine gegenüber der Umhüllungsfläche (12) in Bezug auf die Drehachse (A) radiale Ausnehmung (18) umfasst. Die Erfindung betrifft weiterhin ein Verfahren zum Herstellen einer derartigen Welle, bei welchem zumindest ein Teil der Welle mittels eines Umformverfahrens hergestellt wird.The invention relates to a shaft, in particular for an engine of a motor vehicle, having at least one cylindrically shaped bearing region (10) which extends along an axis of rotation (A) of the shaft and at least one relative to the rotational axis (12) with respect to a circular cylindrical enveloping surface (12). A) axial recess (14), wherein the Lagerbreich (10) additionally comprises at least one relative to the wrapping surface (12) with respect to the axis of rotation (A) radial recess (18). The invention further relates to a method for producing such a shaft, in which at least a part of the shaft is produced by means of a forming process.
Description
Die Erfindung betrifft eine Welle, insbesondere für einen Motor eines Kraftfahrzeugs, der im Oberbegriff des Patentanspruchs 1 angegebenen Art sowie ein Verfahren zum Herstellen einer Welle der im Oberbegriff des Patentanspruchs 7 angegebenen Art.The The invention relates to a shaft, in particular for a motor a motor vehicle specified in the preamble of claim 1 Art and a method for producing a wave in the preamble of claim 7 specified type.
Eine
derartige Welle sowie ein derartiges Verfahren sind beispielsweise
bereits aus der
Aufgabe der vorliegenden Erfindung ist es, eine Welle sowie ein Verfahren zum Herstellen einer Welle zu schaffen, welche eine weitere Gewichtseinsparung ermöglichen.task It is the object of the present invention to provide a shaft and a method to create a shaft, which provides a further weight saving enable.
Die Aufgabe wird erfindungsgemäß durch eine Welle mit den Merkmalen des Patentanspruchs 1 sowie durch ein Verfahren mit den Merkmalen des Patentanspruchs 7 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen sind in den jeweiligen Unteransprüchen angegeben, wobei vorteilhafte Ausgestaltungen der Welle – soweit anwendbar – als vorteilhafte Ausgestaltungen des Verfahrens und umgekehrt anzusehen sind.The The object is achieved by a shaft with the features of claim 1 and by a method solved with the features of claim 7. advantageous Embodiments with expedient and non-trivial developments are specified in the respective subclaims, wherein advantageous embodiments of the shaft - where applicable - as to consider advantageous embodiments of the method and vice versa are.
Eine Welle, welche eine weitere Gewichtseinsparung ermöglicht, ist erfindungsgemäß dadurch geschaffen, dass der Lagerbereich wenigstens eine gegenüber der Umhüllungsfläche in Bezug auf die Drehachse radiale Ausnehmung umfasst. Mit anderen Worten ist am Umfang der Welle wenigstens eine Ausnehmung im Lagerbereich vorgesehen, welche zu einer Kürzung des zylindrischen Anteils führt. Dies ermöglicht neben der dadurch erzielten Gewichtseinsparung eine zusätzliche Verringerung der Reibleistung und dementsprechend niedrigere Lagertemperaturen während des Betriebs der Welle. Da aufgrund der radialen Ausnehmung zusätzlich ein Selbstansaugeffekt von Schmierstoff – beispielsweise Motoröl – ermöglicht ist, ergibt sich darüber hinaus eine höhere Schmierfilmdickenreserve, wodurch die Welle einen geringeren Verschleiß und somit eine erhöhte Lebensdauer besitzt.A Shaft, which allows further weight saving, is inventively created by the Storage area at least one opposite the wrapping surface includes radial recess with respect to the axis of rotation. With others Words is at the periphery of the shaft at least one recess in the storage area provided, which leads to a reduction of the cylindrical portion leads. This allows besides the achieved thereby Weight saving an additional reduction of the frictional loss and accordingly lower storage temperatures during the operation of the shaft. In addition, due to the radial recess a self-priming effect of lubricant - for example Engine oil - is possible, results In addition, a higher lubricant thickness reserve, causing the shaft to wear less and thus has an increased life.
Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zum Herstellen einer Welle gemäß einem der vorhergehenden Ausführungsbeispiele, wobei erfindungsgemäß zumindest ein Teil der Welle mittels eines Umformverfahrens hergestellt wird. Neben den dadurch erzielbaren, zusätzlichen Gewichtseinsparungen der Welle wird durch die Verwendung eines Umformverfahrens zusätzlich eine erhebliche Senkung der Stückkosten erzielt. Zudem handelt es sich bei derartigen Wellen um Massenteile, so dass sich zusätzliche Kostenvorteile mit entsprechend reduzierten Stückkosten ergeben. Dabei hat es sich als vorteilhaft gezeigt, dass als Umformverfahren ein Tiefziehverfahren und/oder ein Innenhochdruck-Umformverfahren verwendet wird. Dies erlaubt eine automatisierbare und schnelle Herstellung auch komplexer Wellengeometrien, wodurch Wellen mit einem verringerten Gesamtgewicht und verbesserten Laufeigenschaften schnell und kostengünstig hergestellt werden können.One Another aspect of the invention relates to a method for manufacturing a shaft according to one of the preceding embodiments, wherein according to the invention at least a part of the shaft is produced by means of a forming process. In addition to that achievable, additional weight savings of the shaft is added by the use of a forming process achieved a significant reduction in unit costs. moreover Such waves are mass parts, so that additional Cost advantages with correspondingly reduced unit costs result. It has proved to be advantageous that as a forming process a deep-drawing process and / or a hydroforming process is used. This allows an automatable and fast Producing even complex wave geometries, thereby creating waves a reduced total weight and improved running properties can be produced quickly and inexpensively.
