Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine according to the preamble of claim 1.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, eine besonders vorteilhafte Brennkraftmaschine bereitzustellen, die insbesondere eine geringes Gewicht und besonders vorteilhaft einen geringen Bauraumbedarf aufweist. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is in particular the object of providing a particularly advantageous internal combustion engine, which in particular has a low weight and particularly advantageously a small space requirement. It is achieved according to the invention by the features of claim 1. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Brennkraftmaschine für ein Kraftfahrzeug, mit einem Motorgehäuse und mit einer Pumpenvorrichtung, die zumindest ein Pumpengehäuse mit einer radialen Dichtfläche, und ein innerhalb des Pumpengehäuses angeordnetes Verdrängerelement, das innerhalb des Pumpengehäuses mit der radialen Dichtfläche des Pumpengehäuses zumindest ein Pumpvolumen begrenzt, aufweist.The invention is based on an internal combustion engine for a motor vehicle, with a motor housing and with a pump device, which defines at least one pump housing with a radial sealing surface, and a displacer disposed within the pump housing, which limits at least one pumping volume within the pump housing with the radial sealing surface of the pump housing , having.
Es wird vorgeschlagen, dass zumindest das die radiale Dichtfläche ausbildende Pumpengehäuse zumindest teilweise einstückig mit dem Motorgehäuse ausgebildet ist. Dadurch kann das Pumpengehäuse vorteilhaft von dem Motorgehäuse ausgebildet werden und dadurch vorteilhaft auf ein zusätzliches Pumpengehäuse verzichtet werden, wodurch insbesondere ein geringes Gewicht und ein vorteilhaft geringer Bauraumbedarf der Brennkraftmaschine erreicht werden kann. Unter einer „Pumpenvorrichtung” soll dabei insbesondere eine Vakuum- bzw. Unterdruckpumpe verstanden werden, die zur Erzeugung eines Druckunterschieds, insbesondere zur Erzeugung eines Unterdrucks, vorgesehen ist. Unter einer „radialen Dichtfläche” soll dabei insbesondere eine vorzugsweise kreisförmige Innenwandung des Pumpengehäuses verstanden werden, welche einen Pumpenraum in radialer Richtung begrenzt. Unter einem „Verdrängerelement” soll insbesondere ein mit der radialen Dichtfläche des Pumpengehäuses in Kontakt stehendes Element verstanden werden, das einen Pumpeninnenraum in zumindest zwei voneinander abgetrennte und gegeneinander abgedichtete Bereiche abtrennt. Dabei rotiert das Verdrängerelement exzentrisch zu einer Mittelachse des Pumpeninnenraums in dem Pumpeninnenraum und erzeugt dadurch zwei Pumpvolumen, die sich in ihrer Größe mit einem Rotationswinkel des Verdrängerelements verändern. Unter einem „Pumpvolumen” soll hierbei insbesondere ein Volumen verstanden werden, das von dem Verdrängerelement, der radialen Dichtfläche und zwei axialen Dichtflächen der Pumpenvorrichtung eingeschlossen wird. Unter „axialen Dichtflächen” sollen insbesondere die Flächen verstanden werden, die den Pumpeninnenraum in einer axialen Richtung begrenzen und abdichten. Unter „einstückig” soll insbesondere stoffschlüssig verbunden, wie beispielsweise durch einen Schweißprozess und/oder Klebeprozess usw., und besonders vorteilhaft angeformt verstanden werden, wie durch die Herstellung aus einem Guss und/oder durch die Herstellung in einem Ein- oder Mehrkomponentenspritzverfahren.It is proposed that at least the pump housing forming the radial sealing surface is at least partially formed in one piece with the motor housing. As a result, the pump housing can advantageously be formed by the motor housing and thereby advantageously dispensed with an additional pump housing, which in particular a low weight and an advantageously low space requirement of the internal combustion engine can be achieved. A "pump device" is to be understood in particular as a vacuum or vacuum pump which is provided for generating a pressure difference, in particular for generating a negative pressure. A "radial sealing surface" is to be understood in particular as meaning a preferably circular inner wall of the pump housing which delimits a pump chamber in the radial direction. A "displacement element" is to be understood in particular as an element in contact with the radial sealing surface of the pump housing, which separates a pump interior into at least two separate and mutually sealed regions. In this case, the displacer rotates eccentrically to a central axis of the pump interior in the pump interior and thereby generates two pumping volumes, which vary in size with a rotation angle of the displacer. A "pump volume" is to be understood here in particular as meaning a volume which is enclosed by the displacement element, the radial sealing surface and two axial sealing surfaces of the pump device. By "axial sealing surfaces" is intended in particular to be understood as meaning the surfaces which bound and seal the pump interior in an axial direction. By "one-piece" should in particular be cohesively connected, as for example by a welding process and / or bonding process, etc., and particularly advantageous molded, as understood by the production of a cast and / or by the production in a single or Mehrkomponentenspritzverfahren.
Weiter wird vorgeschlagen, dass die Brennkraftmaschine einen Zylinderkopf und/oder einen Zylinderkopfdeckel aufweist, die zumindest einen Teil des Pumpengehäuses ausbilden. Dadurch kann die Pumpenvorrichtung besonders vorteilhaft und platzsparend in die Brennkraftmaschine integriert werden. Unter „zumindest einen Teil des Pumpengehäuses ausbilden” soll insbesondere verstanden werden, dass das Pumpengehäuse zu einem Teil von dem Zylinderkopf und zu einem Teil von dem Zylinderkopfdeckel ausgebildet ist. Dabei bilden der Zylinderkopf und der Zylinderkopfdeckel in einem montierten Zustand vorzugsweise die gesamte radiale Dichtfläche und eine axiale Dichtfläche aus. Grundsätzlich ist es auch denkbar, dass ausschließlich der Zylinderkopf oder der Zylinderkopfdeckel die gesamte radiale Dichtfläche und eine axiale Dichtfläche ausbilden.It is further proposed that the internal combustion engine has a cylinder head and / or a cylinder head cover, which form at least a part of the pump housing. As a result, the pump device can be integrated into the internal combustion engine in a particularly advantageous and space-saving manner. By "forming at least a part of the pump housing" is to be understood in particular that the pump housing is formed to a part of the cylinder head and to a part of the cylinder head cover. In this case, the cylinder head and the cylinder head cover in an assembled state preferably form the entire radial sealing surface and an axial sealing surface. In principle, it is also conceivable that only the cylinder head or the cylinder head cover form the entire radial sealing surface and an axial sealing surface.
Ferner wird vorgeschlagen, dass die Brennkraftmaschine einen lösbar mit dem Motorgehäuse verbundenen Pumpendeckel aufweist, der lediglich eine axiale Dichtfläche des Pumpengehäuses ausbildet. Dadurch kann der Pumpeninnenraum der Pumpenvorrichtung besonders vorteilhaft und einfach geschlossen werden. Grundsätzlich ist es aber auch denkbar, dass der Pumpendeckel zumindest einen Teil der radialen Dichtfläche des Pumpengehäuses ausbildet.It is also proposed that the internal combustion engine has a pump cover detachably connected to the motor housing, which only forms an axial sealing surface of the pump housing. As a result, the pump interior of the pump device can be closed particularly advantageously and simply. In principle, however, it is also conceivable that the pump cover forms at least a part of the radial sealing surface of the pump housing.

Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing.
