Abstract
Gegenstand der Erfindung ist ein Verfahren zur Herstellung einer Welle zur Aufnahme einer Klappe in einer Ventilvorrichtung, bei dem eine Vorwelle erzeugt, im Bereich der beiden Enden der Vorwelle je ein Lagersitz erzeugt und in einem Bereich, der zwischen den beiden Lagersitzen angeordnet ist, eine Aufnahme erzeugt wird. Die Aufnahme wird so erzeugt, dass sie zwei Klappen aufnehmen kann und dass die Vorwelle anschließend in einem Bereich, der zwischen den beiden Klappen liegt, durchtrennt wird, so dass die Vorwelle zu zwei Wellen vereinzelt wird.The invention relates to a method for producing a shaft for receiving a flap in a valve device, in which generates a Vorwelle, generates a respective bearing seat in the region of the two ends of the Vorwelle and in a region which is arranged between the two bearing seats, a receptacle is produced. The recording is generated so that it can record two flaps and that the Vorwelle is then cut in an area that lies between the two flaps, so that the Vorwelle is separated into two waves.
Description
Gegenstand der Erfindung ist ein Verfahren zur Herstellung einer Welle zur Aufnahme einer Klappe in einer Ventilvorrichtung, bei dem eine Vorwelle erzeugt wird, im Bereich der beiden Enden der Vorwelle je ein Lagersitz erzeugt wird und in einem Bereich, der zwischen den beiden Lagersitzen angeordnet ist, eine Aufnahme erzeugt wird. Gegenstand der Erfindung ist weiter eine nach diesem Verfahren hergestellte Welle. The invention relates to a method for producing a shaft for receiving a flap in a valve device, in which a Vorwelle is generated, in the region of the two ends of the prerwn ever a bearing seat is generated and in a region which is arranged between the two bearing seats, a recording is generated. The invention further provides a shaft produced by this method.
Derartige Wellen werden in Ventilvorrichtungen von Kraftfahrzeugen, insbesondere als Drosselklappenstutzen eingesetzt und sind somit bekannt. Diese Ventilvorrichtungen besitzen ein Gehäuse, eine in dem Strömungskanal angeordnete Klappe zum Verschließen des Strömungskanals, wobei die Klappe an einer Welle befestigt ist und die Welle mittels eines Elektromotors und eines zwischengeschalteten Getriebes drehbar in dem Gehäuse gelagert ist. Jede danach hergestellte Welle besitzt zwei Lagersitze und eine Aufnahme für eine Klappe. Hierzu wird jede Welle mit dem entsprechenden Aufwand bearbeitet werden. Such waves are used in valve devices of motor vehicles, in particular as throttle body and are thus known. These valve devices have a housing, a valve arranged in the flow channel for closing the flow channel, wherein the flap is fixed to a shaft and the shaft is rotatably supported by means of an electric motor and an intermediate gear in the housing. Each shaft produced thereafter has two bearing seats and a receptacle for a flap. For this purpose, each shaft will be processed with the appropriate effort.
Aufgabe der Erfindung ist es ein Verfahren zu schaffen, mit dem eine eingangs genannte Welle einfacher herzustellen ist. Aufgabe der Erfindung ist es weiterhin, eine einfacher herzustellende Welle zu schaffen.The object of the invention is to provide a method with which an aforementioned shaft is easier to manufacture. The object of the invention is also to provide a simpler to produce shaft.
Gelöst wird die erste Aufgabe dadurch, dass die Aufnahme so erzeugt wird, dass sie zwei Klappen aufnehmen kann und dass die Vorwelle anschließend in einem Bereich, der zwischen den beiden Klappen liegt, durchtrennt wird, so dass die Vorwelle zu zwei Wellen vereinzelt wird. The first object is achieved in that the recording is generated so that it can accommodate two flaps and that the Vorwelle is then cut in an area that lies between the two flaps, so that the Vorwelle is separated into two waves.
Der Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass die Vorwelle nicht mehr als eine Endwelle erzeugt wird, sondern dass eine Vorwelle nunmehr von zwei Endwellen umfasst und mit dem Vereinzeln aus einer Vorwelle zwei Wellen entstehen. Damit lassen sich Bearbeitungs- und Handhabungsvorgänge einsparen, so dass die so hergestellten Wellen besonders kostengünstig sind. Der zusätzliche Bearbeitungsschritt des Vereinzelns ist dabei vernachlässigbar.The advantage of the method according to the invention is that the pre-wave is no longer generated as a final wave, but that a pre-wave now includes two end waves and with the singling from a pre-wave two waves arise. This allows machining and handling operations to be saved, so that the waves thus produced are particularly cost-effective. The additional processing step of the singulation is negligible.
Gemäß einer vorteilhaften Ausgestaltung wird die Trennstelle der jeweiligen Welle nach dem Vereinzeln bearbeitet. Mit diesem Bearbeitungsschritt lassen sich eventuelle Rückstände des Vereinzelns entfernen, um zu verhindern, dass dadurch die Montage oder der spätere Betrieb der Ventilvorrichtung beeinflusst wird.According to an advantageous embodiment, the separation point of the respective shaft is processed after separation. With this processing step, any residues of the separation can be removed, in order to prevent that thereby the assembly or the subsequent operation of the valve device is influenced.
Die zweite Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Welle ein Ende zur Anbindung an ein Getriebe einer Ventilvorrichtung, einen Lagersitz und eine Aufnahme für eine Klappe einer Ventilvorrichtung besitzt, wobei sich die Aufnahme für die Klappe bis an das gegenüberliegende Ende der Welle erstreckt.The second object is achieved in that the shaft has an end for connection to a transmission of a valve device, a bearing seat and a receptacle for a flap of a valve device, wherein the receptacle for the flap extends to the opposite end of the shaft.
Durch dieser Ausbildung der Welle, insbesondere der Erstreckung der Aufnahme bis zu einem Ende der Welle ist es möglich zwei Wellen aus einer Vorwelle und somit besonderes kostengünstig zu erzeugen.This design of the shaft, in particular the extension of the recording up to one end of the shaft, it is possible to produce two waves from a Vorwelle and thus special cost.
In vorteilhaften Ausgestaltungen ist die Aufnahme als Schlitz oder Absatz ausgebildet. Diese Aufnahmen haben den Vorteil, die Klappe aufgrund ihrer geometrischen Ausprägung aufzunehmen. Die erforderliche Verschraubung der Klappe dient ausnahmslos dem Fixieren der Klappe an der Welle.In advantageous embodiments, the receptacle is designed as a slot or shoulder. These recordings have the advantage of accommodating the flap due to its geometric shape. The required screw connection of the flap invariably serves to fix the flap on the shaft.
