Abstract
Description
Die Erfindung betrifft eine Schaltwalze für den Einsatz in Ansaugvorrichtungen mit einem im Wesentlichen zylindrischen Gehäuse, mit einem Mitnehmer, der mit einer Antriebsvorrichtung in Wirkverbindung steht, und mit Öffnungen, die die fluidische Verbindung zwischen verschiedenen Bereichen der Ansaugvorrichtung gewährleistet.The The invention relates to a shift drum for use in Intake devices with a substantially cylindrical housing, with a driver, with a drive device in operative connection stands, and with openings, the fluidic connection ensured between different areas of the suction device.
Eine
derartige Schaltwalze ist beispielsweise aus der Verwendung in einem
Schaltsaugrohr gemäß der
Aufgabe der Erfindung ist es daher, eine Schaltwalze zu verschaffen, die auf besonders einfache und kostengünstige Weise herzustellen ist und vielseitig einzusetzen ist.task The invention is therefore to provide a shift drum, the to produce in a particularly simple and cost-effective manner is and is versatile.
Diese Aufgabe wird dadurch gelöst, dass die Schaltwalze als Stanzteil mit Ausstanzungen und Stegen ausgeführt ist, derart, die Schaltwalze als Stanzteil mit Ausstanzungen ausgeführt ist, derart, dass das Stanzteil im eingebauten Zustand eine im Wesentlichen zylindrische Form aufweist, wobei die Ausstanzungen die fluidische Verbindung zwischen zwei Ansaugbereichen gewährleisten.These The object is achieved in that the shift drum as a stamped part executed with cutouts and webs, such, the Shift drum executed as a stamped part with punched is such that the stamped part in the installed state is a substantially cylindrical shape, wherein the punched out the fluidic Ensure connection between two intake areas.
Auf diese Art und Weise wird eine Schaltwalze bereit gestellt, die besonders einfach und kostengünstig zu produzieren ist. Dabei ist es besonders vorteilhaft, wenn das Stanzteil Stege aufweist, die im eingebauten Zustand derart umgeformt sind, dass sie den Mitnehmer bilden, wobei der Mitnehmer kunststoffumspritzt ist und die Sachaltwalze zur Antriebsvorrichtung gerichtet fluiddicht abschließt. Das Stanzteil kann auch Prägeflächen aufweisen, derart, dass vorstehende Bereiche Dichtflächen formen. Eine derart ausgeführte Schaltwalze korrespondiert auf besonders einfache und sichere Weise mit dem jeweiligen Gehäuseteil in der Ansaugvorrichtung, in dem sie gelagert ist. Dadurch dass das Stanzteil korrespondierende Vorsprünge und Ausnehmungen aufweist, die eine formschlüssige Verbindung der Stoßseiten des Stanzteils gewährleisten, kann die Einbauform der Schaltwalze auf einfache Art und Weise realisiert werden. Als besonders vorteilhaft für die Montage der Schaltwalze in der Ansaugvorrichtung hat es sich als günstig erwiesen, dass die Schaltwelle eine gewisse Konizität aufweist. Um eine höhere Verschleißfestigkeit aufzuweisen, oder aber auch die Schaltwalze hinsichtlich ihrer Abdichtfunktion auf den Werkstoff der Ansaugrohrvorrichtung genau abstimmen zu können, kann das Stanzteil auch eine Beschichtung aufweisen.On this way, a shift drum is provided, the particular easy and inexpensive to produce. It is It is particularly advantageous if the stamped part webs, the are converted in the installed state such that they are the driver form, wherein the driver is plastic-molded and the cold roller directed towards the drive device fluid-tight manner. The stamped part can also have stamping surfaces, such that protruding areas form sealing surfaces. A thus executed shift drum corresponds to particular simple and safe way with the respective housing part in the suction device in which it is stored. As a result of that the punched part has corresponding projections and recesses, the one positive connection of the butt sides ensure the stamped part, the installation form of the shift drum be realized in a simple manner. As a particularly advantageous for mounting the shift drum in the aspirator it has proven to be favorable that the shift shaft has a certain conicity. To a higher one Have wear resistance, or even the shift drum in terms of their sealing function on the material of the Ansaugrohrvorrichtung To be able to vote exactly, the stamped part can also be a Have coating.
Insbesondere kann die Schaltwalze in einem Schaltsaugrohr eingesetzt werden mit nebeneinander angeordneten Einzelsaugrohren die jeweils zu einem Zylinder führen und zwei Öffnungen zu einem Sammelvolumen aufweisen, derart dass ein kürzerer und ein längerer wirksamer Kanal in jedem Einzelsaugrohr ansteuerbar ist, wobei im Bereich der zweiten Öffnung eine Längsbohrung vorgesehen ist, in der die Schaltwalze angeordnet ist.Especially the shift drum can be used in a intake manifold with juxtaposed individual intake pipes each to a Cylinder lead and two openings to a collection volume such that a shorter and a longer effective channel is controllable in each individual intake manifold, wherein in Area of the second opening a longitudinal bore is provided, in which the shift drum is arranged.
Auch ist es möglich die Schaltwalze in einem Resonanzsaugrohr ein zu setzen mit nebeneinander angeordneten Resonanzräumen, die durch eine Gehäuseteil getrennt sind, wobei in dem Gehäuseteil die Schaltwalze gelagert ist.Also Is it possible the shift drum in a resonance intake manifold to be set with resonance chambers arranged side by side, which are separated by a housing part, wherein in the Housing part, the shift drum is mounted.
Im Folgenden wird unter Bezugnahme auf die Zeichnung Ausführungsbeispiele der Erfindung näher erläutert.in the Embodiments will be described below with reference to the drawings the invention explained in more detail.
