Abstract
Description
Die Erfindung betrifft eine Vakuumpumpe, insbesondere für Bremskraftverstärkersysteme für Kraftfahrzeuge, mit einem Kunststoffschieber oder -flügel, welche z. B. als Monoflügelzellenbauart bekannt ist. Dabei sind die bisher bekannten Kunststoffschieber für Flügelzellenpumpen meistens massiv ausgeführt, was zu relativ langen Zykluszeiten beim Spritzgießen und zu hohen Kosten bei der Herstellung als Spritzgussteil führt. Außerdem führt das Gewicht zu hohen Massenkräften und somit zu einer erhöhten Belastung und einem höheren Verschleiß der Pumpen. Weiterhin sind Kunststoffschieber bekannt, welche mit randoffenen Hohlräumen versehen und verrippt sind. Die randoffene Struktur hat eine geringe Stabilität. Es besteht auch die Gefahr, dass Schwachstellen durch Bindenähte, Einfallstellen und stark anisotrope Materialeigenschaften entstehen. Außerdem ist das Spritzgusswerkzeug durch Verwendung von Kernen relativ aufwendig und wenig robust.The invention relates to a vacuum pump, in particular for brake booster systems for motor vehicles, with a plastic slide or wing, which z. B. as a monoflower cell type is known. Here are the previously known plastic slides for vane pumps mostly solid, resulting in relatively long cycle times in injection molding and leads to high costs in the production as an injection molded part. It also leads Weight too high mass forces and thus to an increased Strain and a higher Pump wear. Plastic slides are also known, which have open edges cavities are provided and ribbed. The open structure has a slight Stability. There is also a risk of weak spots due to weld lines, sink marks and strongly anisotropic material properties arise. Besides, is the injection molding tool is relatively expensive due to the use of cores and not very robust.
Es ist daher Aufgabe der Erfindung, eine verbesserte Vakuumpumpe darzustellen.It is therefore an object of the invention to represent an improved vacuum pump.
Die Aufgabe wird gelöst durch eine Vakuumflügelzellenpumpe mit einem Kunststoffschieber oder -flügel, welcher sich dadurch auszeichnet, dass der Schieber oder Flügel im Inneren einen oder mehrere Hohlräume aufweist, wobei die Hohlräume bis auf je eine Injektions-Öffnung ringsum nach außen hin geschlossen sind. Erfindungsgemäß sind die Hohlräume des Kunststoffschiebers in einem Spritzgussverfahren durch Injizieren eines Fluids (Gas oder Flüssigkeit) unter Druck (Innendruck-Injektionsspritzgießen) hergestellt. Bevorzugt wird ein Kunststoffschieber, bei welchem. die Injektionsöffnung zentral auf einer der beiden breiten Seitenflächen angeordnet ist.The task is solved by a vacuum vane pump with a plastic slide or wing, which is characterized by that the slider or wing has one or more cavities inside, the cavities to one injection port each all around to the outside are closed. According to the cavities of the Plastic slide valve in an injection molding process by injection a fluid (gas or liquid) manufactured under pressure (internal pressure injection molding). Prefers becomes a plastic slide, in which. the injection opening centrally is arranged on one of the two wide side surfaces.
Weiterhin wird eine Vakuumpumpe mit einem Kunststoffschieber bevorzugt, bei welchem die Injektionsöffnung zentral auf einer der beiden schmalen Seitenflächen angeordnet ist.Furthermore, a vacuum pump with a plastic slide is preferred, in which the injection opening is central is arranged on one of the two narrow side surfaces.
Eine erfindungsgemäße Vakuumpumpe mit einem Kunststoffschieber zeichnet sich dadurch aus, dass die Injektionsöffnung nach Beendigung der Fluidinjektion verschlossen werden kann, z. B. durch Schmelze, die beim Spritzgussvorgang nachgeschoben wird, oder einen eingegossenen oder eingepressten oder eingeclipsten oder eingeschweißten oder eingeschraubten oder eingenieteten oder eingeklebten Stopfen bzw. durch nachträgliches Aufschmelzen der Injektionsstelle.A vacuum pump according to the invention with a plastic slide is characterized in that the injection port can be closed after the end of the fluid injection, e.g. B. by melt that is replenished during the injection molding process, or a cast in or pressed in or clipped in welded or screwed or riveted or glued in plugs or through subsequent Melt the injection site.
Die Aufgabe wird weiterhin gelöst durch eine Vakuumpumpe mit einem Kunststoffschieber oder -flügel, insbesondere für Bremskraftverstärkersysteme für Kraftfahrzeuge, wobei der Schieber oder Flügel im Inneren eine aufgeschäumte, poröse Materialstruktur aufweist, während er an seiner Oberfläche eine kompakte, geschlossene Außenhaut aufweist. Das hat den Vorteil, dass eine sogenannte Sandwichstruktur mit hoher Festigkeit und relativ geringem Gewicht entsteht.The task is still solved by a vacuum pump with a plastic slide or wing, in particular for brake booster systems for motor vehicles, being the slider or wing inside a foamed, porous Has material structure while he has one on his surface compact, closed outer skin having. This has the advantage of a so-called sandwich structure with high strength and relatively low weight.
Weiterhin wird eine Vakuumpumpe mit Kunststoffschieber bevorzugt, bei welchem die aufgeschäumte Materialstruktur in einem Spritzgießverfahren durch Beimischen eines Gases erzeugt wird. Das hat den Vorteil, dass beim Abkühlen des Kunststoffes sich an der Gehäusewand eine dichte Struktur bildet, während im Inneren eine poröse Struktur entsteht. Im Material baut sich ein Gasdruck auf, der weitgehend verhindert, dass das Teil beim Abkühlen schwindet und sich Einfallstellen bilden.Furthermore, a vacuum pump with a plastic slide preferred, in which the foamed material structure in one injection molding is generated by adding a gas. That has the advantage, that when cooling of the plastic on the housing wall forms a dense structure while inside a porous Structure arises. A gas pressure builds up in the material, which largely prevents the part from shrinking when cooling and sink marks form.
Eine erfindungsgemäße Vakuumpumpe zeichnet sich dadurch aus, dass das Beimischen eines Gases auf chemischem Weg durch Zusatz eines Gasbildners erfolgt. Das hat den Vorteil, dass der Gasbildner sich beim Erhitzen in der Spritzgussmaschine zersetzt und Gas freisetzt.A vacuum pump according to the invention draws is characterized by the fact that the admixing of a gas on chemical Is done by adding a gas generator. That has the advantage, that the gas generator is heated up in the injection molding machine decomposes and releases gas.
Eine weiter erfindungsgemäße Vakuumpumpe zeichnet sich dadurch aus, dass das Beimischen eines Gases durch Einblasen von Gas in die flüssige Kunststoffmasse erfolgt. Dieses Verfahren hat den Vorteil eines einfachen physikalischen Vorganges. Auch wird eine Vakuumpumpe bevorzugt, bei welcher das Beimischen eines Gases durch Einspritzen einer Flüssigkeit erfolgt, welche verdampft und somit den Aufschäumprozess verursacht.Another vacuum pump according to the invention is characterized in that the admixing of a gas by Blowing gas into the liquid plastic mass he follows. This method has the advantage of a simple physical one Process. A vacuum pump in which the admixing is also preferred a gas by injecting a liquid which evaporates and thus the foaming process caused.
Eine erfindungsgemäße Vakuumpumpe zeichnet sich dadurch aus, dass der Schieber oder Flügel einen geringen Aufschäumgrad von beispielsweise 1,5 bis 10 % aufweist. Das hat den Vorteil, dass die Maßgenauigkeit des Schiebers erhöht wird und Einfallstellen vermieden werden.A vacuum pump according to the invention draws is characterized in that the slide or wing has a low degree of foaming for example, 1.5 to 10%. This has the advantage that the dimensional accuracy of the slide increased and sink marks are avoided.
Eine weitere erfindungsgemäße Vakuumpumpe zeichnet sich dadurch aus, dass der Schieber oder Flügel einen hohen Aufschäumgrad von 10 bis 80 % aufweist. Das hat den Vorteil, dass das Gewicht des Flügels erheblich reduziert wird.Another vacuum pump according to the invention is characterized in that the slide or wing one high degree of foaming from 10 to 80%. This has the advantage that the weight of the wing is significantly reduced.
Eine weitere erfindungsgemäße Vakuumpumpe weist an einem oder beiden Enden des Schiebers, welche gleitende Dichtflächen gegenüber einer Gehäusekontur der Flügelzellenvakuumpumpe darstellen, separate Kappen auf. Erfindungsgemäß stellen die Kappen Verschleißschutzkappen und/oder reibungsarme Gleitkappen und/oder Dichtkappen dar.Another vacuum pump according to the invention has one or both ends of the slider, which sliding sealing surfaces across from a housing contour the vane vacuum pump represent separate caps. According to the invention, the caps provide wear protection caps and / or low-friction sliding caps and / or sealing caps.
Eine weitere erfindungsgemäße Vakuumpumpe zeichnet sich dadurch aus, dass die Kappen aus einem anderen Material als der Kunststoffschieber hergestellt sind.Another vacuum pump according to the invention is characterized in that the caps made of a different material than the plastic slide are made.
Bevorzugt wird auch eine Vakuumpumpe, bei welcher die Kappen durch Angießen oder Anschweißen oder Ankleben oder Aufclipsen oder Aufpressen fest mit dem Schieber verbunden sein können. Das hat den Vorteil, dass keine Relativbewegung zwischen dem Schieber und den Kappen im Betrieb auftreten kann.A vacuum pump is also preferred, in which the caps can be firmly connected to the slide by casting or welding or gluing or clipping on or pressing on. This has the advantage that there is no relative movement between the slide and the caps in the Operation may occur.
Weiterhin wird eine Vakuumpumpe bevorzugt, bei welcher die Kappen aufgesteckt sind und zwischen Schieber und Kappen eine Relativbewegung möglich ist. Dadurch können funktionsbedingte und fertigungsbedingte Spiele ausgeglichen werden.Furthermore, a vacuum pump is preferred in which the caps are attached and between slide and Caps a relative movement possible is. This allows function-related and production-related games are balanced.
