Description

Beschreibung description
Verfahren zur Herstellung einer Welle für eine Ventilvorrichtung und Ventilvorrichtung mit einer nach dem Verfahren hergestellten Welle Method for producing a shaft for a valve device and valve device with a shaft produced by the method
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. Derartige Wellen werden in Ventilvorrichtungen von Kraft¬ fahrzeugen, 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. 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. Such waves are used in valve devices of power ¬ vehicles, in particular as a 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 record two flaps and that the Vorwelle then in a region that lies between the two flaps, is cut, 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 Vereinzeins 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 instead that a pre-wave now includes two end waves and arise with the singling from a previous wave two waves. This allows machining and handling operations to be saved, so that the waves thus produced are particularly cost-effective. The additional processing step of Vereinzeins is negligible.
Gemäß einer vorteilhaften Ausgestaltung wird die Trennstelle der jeweiligen Welle nach dem Vereinzeln bearbeitet. Mit diesem Bearbeitungsschritt lassen sich eventuelle Rückstände desAccording to an advantageous embodiment, the separation point of the respective shaft is processed after separation. With this processing step, any residues of the
Vereinzeins entfernen, um zu verhindern, dass dadurch die Montage oder der spätere Betrieb der Ventilvorrichtung beeinflusst wird. Remove it one by one to prevent it from affecting the assembly or later operation of the valve device.
Die zweite Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Welle ein Ende zur Anbindung an ein Getriebe einer Ventil¬ vorrichtung, 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. 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 er¬ zeugen . 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. 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 , By this design of the shaft, in particular the extension of the recording to an end of the shaft, it is possible two waves from a previous wave and thus special testify inexpensive to he ¬. 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.

The Vorwelle 1 has two ends 2, 3 for connection to a respective transmission, and two bearing seats 4, 5. Between the bearing seats 4, 5, a slot 6 is introduced into the pre-wave 1, whose length is greater than the diameter of two valves of the valve devices , Perpendicular to the slot 6, two holes 7, 8 are arranged in the prerwelle 1. The line in the middle of the pre-wave 1 symbolizes the dividing plane when separating the waves from the pre-wave 1.
Fig. 2 zeigt eine aus einer Vorwelle vereinzelte Welle 9 mit dem Ende 2 für die Getriebeanbindung und dem Lagersitz 4. Die Welle 9 weist eine Aufnahme 10 für die Klappe der Ventilvorrichtung auf. Das Befestigen der Klappe an der Welle 9 erfolgt über eine nicht dargestellt Schraube, die in die Bohrung 7 eingesetzt wird und über die die Klappe mit der Welle 9 verschraubt wird. Das Ende 11 der Welle 9 wurde nach dem Vereinzeln mechanisch bearbeitet, z. B. Entgraten oder Schleifen, um störende Bearbeitungsspuren des Vereinzeins zu beseitigen. Fig. 2 shows an isolated from a preshaft shaft 9 with the end 2 for the gear connection and the bearing seat 4. The shaft 9 has a receptacle 10 for the flap of the valve device.

The end 11 of the shaft 9 was machined after separation, z. B. deburring or grinding to eliminate annoying processing traces of Vereinzeins.
Die Welle 12 in Fig. 3 unterscheidet sich von Fig. 2 dadurch, dass die Aufnahme für die Klappe als Absatz 13 ausgebildet ist, in den die Klappe eingesetzt wird und mittels zweier Schrauben über entsprechende Bohrungen 7, 7 x an der Welle 12 befestigt wird. Das Ende 11 der Welle 12 wurde nach dem Vereinzeln ebenfalls me¬ chanisch nachbearbeitet. The shaft 12 in Fig. 3 differs from Fig. 2 in that the receptacle for the flap is formed as a paragraph 13, in which the flap is inserted and is fastened by means of two screws via corresponding holes 7, 7 x on the shaft 12 , The end 11 of the shaft 12 was also machined me ¬ chanically after separation.
