Description
Die vorliegende Erfindung betrifft eine Ladeeinrichtung, insbesondere einen Abgasturbolader, einer Brennkraftmaschine eines Fahrzeuges, mit einer Wastegate-Ventileinrichtung, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a charging device, in particular an exhaust gas turbocharger, an internal combustion engine of a vehicle, with a wastegate valve device, according to the preamble of claim 1.
Ladeeinrichtungen, insbesondere Abgasturbolader, dienen der Leistungssteigerung von Brennkraftmaschinen. Dabei treibt ein Abgas der Brennkraftmaschine eine Turbine der Ladeeinrichtung an, welche durch eine Welle mit einem Verdichter gekoppelt ist. Somit wird eine der Brennkraftmaschine zuzuführende Ladeluft verdichtet. Um die Leistung der Ladeeinrichtung begrenzen zu können, weist die Ladeeinrichtung üblicherweise eine Wastegate-Ventileinrichtung auf, die einen Teil der Abgase an der Turbine vorbeiführen kann. Zu diesem Zweck weist die Wastegate-Ventileinrichtung einen Ventilsitz auf, auf dem ein Ventilteller sitzt, der bei Bedarf durch eine Bewegung geöffnet werden kann. Nachteilig dabei ist, dass die Wastegate-Ventileinrichtung durch thermische Verzüge bei unterschiedlichen Betriebsbedingungen und durch Verschleiß ihre dichtende Funktion im geschlossenen Zustand verliert. Hierzu tragen auch Bauteiltoleranzen der Wastegate-Ventileinrichtung bei. Weiter entstehen durch die Toleranzen, durch die thermischen Verzüge, sowie durch den Verschleiß Lücken zwischen den Bauteilen, die ein sogenanntes Spiel zwischen den einzelnen Bauteilen erlauben. Dies führt insbesondere dazu, dass bei gewissen Betriebsbedingungen der Brennkraftmaschine, insbesondere durch Anregung von Resonanzfrequenzen der Wastegate-Ventileinrichtung, unerwünschte Geräusche entstehen.Charging devices, in particular exhaust gas turbochargers, serve to increase the power of internal combustion engines. In this case, an exhaust gas of the internal combustion engine drives a turbine of the charging device, which is coupled by a shaft with a compressor. Thus, a charge air to be supplied to the internal combustion engine is compressed. In order to limit the power of the charging device, the charging device usually has a wastegate valve device, which can pass a part of the exhaust gases to the turbine. For this purpose, the wastegate valve device has a valve seat on which a valve disk is seated, which can be opened by a movement if necessary. The disadvantage here is that the wastegate valve device loses its sealing function in the closed state by thermal distortion at different operating conditions and by wear. Component tolerances of the wastegate valve device also contribute to this. Next created by the tolerances, by the thermal distortion, as well as by the wear gaps between the components, which allow a so-called game between the individual components. This leads, in particular, to unwanted noise occurring under certain operating conditions of the internal combustion engine, in particular by excitation of resonance frequencies of the wastegate valve device.
Die vorliegende Erfindung beschäftigt sich daher mit dem Problem, für eine gattungsgemäße Ladeeinrichtung eine verbesserte oder zumindest alternative Ausführungsform anzugeben, die sich insbesondere durch ein verbessertes Abdichtverhalten der Wastegate-Ventileinrichtung und/oder zu einer Verbesserung der akustischen Eigenschaften der Ladeeinrichtung beiträgt.The present invention therefore deals with the problem of providing for a generic charging device an improved or at least alternative embodiment, which contributes in particular by an improved sealing behavior of the wastegate valve device and / or to improve the acoustic properties of the charging device.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruches gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, bei einer Ladeeinrichtung, insbesondere einem Abgasturbolader einer Brennkraftmaschine eines Kraftfahrzeuges, mit einer Wastegate-Ventilvorrichtung, welche einen Ventilteller und einen Ventilsitz aufweist, den Ventilteller flexibel zu gestalten. Der Ventilteller ist also insbesondere federnd. Alternativ oder zusätzlich kann der Ventilsitz derart ausgebildet sein, dass er flexibel ist. Der Ventilsitz kann also insbesondere federnd sein. Zudem oder optional weist der Ventilsitz und/oder der Ventilteller eine gefederte Dichtung auf, welche federnd angebracht ist/sind. Diese Ausführungsformen gewährleisten durch die flexible und abdichtende Anordnung zwischen Ventilsitz und Ventilteller eine verbesserte Abdichtung der Wastegate-Ventileinrichtung, insbesondere auch bei Änderungen der thermischen Gegebenheiten, also bei unterschiedlichen Temperaturen und/oder beim Verschleiß der Ladeeinrichtung. Zudem führt die flexible Anordnung zu einer Unterdrückung der durch die Brennkraftmaschine übertragenen Schwingungen und somit zu einer Unterdrückung der unerwünschten Akustik. Von besonderem Vorteil ist zudem, dass mit der erfindungsgemäßen Ausgestaltung Bauteiltoleranzen ausgeglichen werden können.The present invention is based on the general idea, in a charging device, in particular an exhaust gas turbocharger of an internal combustion engine of a motor vehicle, with a wastegate valve device having a valve plate and a valve seat to make the valve disk flexible. The valve plate is therefore particularly resilient. Alternatively or additionally, the valve seat may be designed such that it is flexible. The valve seat can thus be particularly resilient. In addition or optionally, the valve seat and / or the valve disk to a sprung seal, which is resiliently mounted / are. These embodiments ensure by the flexible and sealing arrangement between the valve seat and valve disc an improved sealing of the wastegate valve device, in particular even with changes in the thermal conditions, ie at different temperatures and / or wear of the charger. In addition, the flexible arrangement leads to a suppression of the vibrations transmitted by the internal combustion engine and thus to a suppression of unwanted acoustics. Of particular advantage is also that can be compensated with the inventive design component tolerances.
Gemäß einer weiteren Ausführungsform ist die Dichtung am Ventilteller und/oder am Ventilsitz aus einem Werkstoff ausgebildet, der flexibel ist. Umfasst die Wastegate-Ventilvorrichtung mehrere Dichtungen am Ventilteller und/oder am Ventilsitz, so kann eine oder alternativ mehrere dieser Dichtungen eine solche flexible Eigenschaft aufweisen. Als flexible Werkstoffe seien hier beispielsweise hitzebeständige Kunststoffe erwähnt.According to a further embodiment, the seal is formed on the valve plate and / or on the valve seat made of a material which is flexible. If the wastegate valve device comprises a plurality of seals on the valve disk and / or on the valve seat, then one or, alternatively, a plurality of these seals may have such a flexible property. As flexible materials, for example, heat-resistant plastics are mentioned here.
Eine weitere vorteilhafte Ausführungsform weist zumindest eine Federeinrichtung auf, die die Dichtung des Ventiltellers gegen den Ventilsitz drückt und somit vorspannt, wodurch eine flexible Anordnung zwischen Ventilteller und Ventilsitz erreicht wird. Alternativ ist auch eine Anordnung vorstellbar, bei der die Federeinrichtung die Dichtung des Ventilsitzes gegen den Ventilteller vorspannt. Es sei bemerkt, dass benannte Federeinrichtung zumindest teilweise in den Ventilteller eingearbeitet sein kann. Die Federeinrichtung kann also insbesondere in Federöffnungen des Ventilssitzes eingearbeitet sein, die außerhalb der Öffnung des Ventilssitzes liegen, wobei die Federeinrichtung teilweise aus der entsprechenden Federöffnung herausragt. Bei Federeinrichtungen des Ventiltellers ist dieser Aufbau entsprechend anzuwenden, wobei die Federöffnungen vorzugsweise im Bereich der Dichtung liegen.A further advantageous embodiment has at least one spring device which presses the seal of the valve disk against the valve seat and thus biases, whereby a flexible arrangement between the valve disk and the valve seat is achieved. Alternatively, an arrangement is conceivable in which the spring device biases the seal of the valve seat against the valve disk. It should be noted that named spring means may be at least partially incorporated in the valve disk. The spring device can thus be incorporated in particular in spring openings of the valve seat, which lie outside the opening of the valve seat, wherein the spring device protrudes partially from the corresponding spring opening. In the case of spring devices of the valve disk, this structure is to be applied correspondingly, the spring openings preferably being in the region of the seal.
Als besonders vorteilhafte Federeinrichtungen sei hier auf Tellerfedern hingewiesen, deren Größe an die Größe der Öffnung des Ventilssitzes bzw. an die Größe des Ventiltellers angepasst ist. Auch ein Wählbalg und/oder ein Membranbalg ist Bestandteil einer bevorzugten Federeinrichtung.As a particularly advantageous spring means should be noted here on disc springs whose size is adapted to the size of the opening of the valve seat or to the size of the valve disk. A selector bellows and / or a diaphragm bellows is also part of a preferred spring device.
Die Federeinrichtung kann zweckgemäß aus Materialien bestehen, die den gegebenen Bedienungen gewachsen sind. Hierbei sei beispielsweise auf korrosionsbeständige und verschleißfeste Materialien, wie etwa Nickelbasislegierungen, hingewiesen.The spring device may suitably consist of materials that are up to the given operations. Reference is made, for example, to corrosion-resistant and wear-resistant materials, such as nickel-based alloys.
Benannte Dichtungen können auf beliebige Weise mit der entsprechenden Federeinrichtung und/oder mit dem entsprechenden Ventilteller und/oder Ventilsitz verbunden sein. Die Dichtung kann also insbesondere durch Verclipsen oder Verschweißen mit der entsprechenden Filtereinrichtung gekoppelt sein.Named seals can be connected in any way with the corresponding spring device and / or with the corresponding valve plate and / or valve seat. The seal can therefore be coupled in particular by clipping or welding to the corresponding filter device.
Bei einer vorteilhaften Ausführungsform weist die Wastegate-Ventileinrichtung eine Spindel auf, die durch die Übertragung einer Bewegung, insbesondere einer Rotation, die Öffnung zwischen Ventilteller und Ventilsitz herstellt. Die Spindel und der Ventilteller sind gemäß dieser vorteilhaften Ausführungsform aus einem einzigen zusammenhängenden Werkstoff hergestellt. Die Spindel und der Ventilteller können also insbesondere als ein einstückiges Gussteil in einem Gussverfahren hergestellt werden. Dies vereinfacht insbesondere die Herstellung und die Montage der Wastegate-Ventileinrichtung und/oder ist durch den Verzicht auf eine Verbindung zwischen Ventilteller und Spindel verschleißbeständiger.In an advantageous embodiment, the wastegate valve device has a spindle which, by the transmission of a movement, in particular a rotation, establishes the opening between the valve disk and the valve seat. The spindle and the valve disk are made according to this advantageous embodiment of a single coherent material. The spindle and the valve disk can thus be produced in particular as a one-piece casting in a casting process. This simplifies in particular the production and assembly of the wastegate valve device and / or is more resistant to wear by dispensing with a connection between valve disk and spindle.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.
