Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist, an der zumindest ein einen Kolben tragendes Pleuel angelenkt ist, wobei der Kolben in einem von einem Zylinderkopf abgedeckten Zylinder bewegbar ist, wobei in den Zylinderkopf Gaswechselventile eingebaut sind, die über Gaswechselkanäle mit einer Abgasleitung und einer Ladeluftleitung verbunden sind und wobei ein Abgasturbolader vorgesehen ist, der mittels einer Tragvorrichtung an der Brennkraftmaschine befestigt ist und mit der Abgasleitung und der Ladeluftleitung unter Einschaltung eines Ladeluftkühlers verbunden ist.The The invention relates to an internal combustion engine with a crankcase, in a crankshaft is rotatably mounted on the at least one a piston bearing connecting rod is articulated, wherein the piston in a cylinder covered by a cylinder head is movable, wherein gas cylinder valves are installed in the cylinder head, the gas exchange channels with a Exhaust pipe and a charge air line are connected and wherein an exhaust gas turbocharger is provided, which by means of a support device is attached to the internal combustion engine and with the exhaust pipe and the charge air line connected with the involvement of a charge air cooler is.
Eine
derartige Brennkraftmaschine ist aus der
Der Erfindung liegt die Aufgabe zugrunde, solche Beschädigungen an dem Abgasturbolader und/oder der Tragvorrichtung zu vermeiden.Of the Invention is based on the object such damage to avoid the exhaust gas turbocharger and / or the support device.
Diese Aufgabe wird dadurch gelöst, dass eine schwingungsabsorbierende und längenverstellbare Abstützvorrichtung zwischen dem Abgasturbolader und der Brennkraftmaschine vorgesehen ist und dass die Abstützvorrichtung an dem Abgasturbolader fern von der Tragvorrichtung befestigt ist. Mit einer solchen schwingungsabsorbierenden und längenverstellbaren Abstützvorrichtung werden Beschädigungen sicher vermieden, wobei die Abstützvorrichtung so ausgelegt ist, dass keine Verspannungen zwischen den einzelnen Bauteilen auftreten. Die von dem Abgasturbolader wegweisende Befestigungsseite der Abstützvorrichtung ist an einem beliebigen Gehäuseteil der Brennkraftmaschine befestigt. Dieses Gehäuseteil, beispielsweise das Kurbelgehäuse, ein Zylinderkopf oder ein vorderer Deckel der Brennkraftmaschine, ist zur Aufnahme der eingeleiteten Kräfte ausgelegt. Die Längenverstellbarkeit ermöglicht die selbstständige Anpassung an wärmedehnungsbedingte Längenänderungen ohne eine Behinderung der Ausdehnung. Solche wärmedehnungsbedingten Längenänderungen ergeben sich insbesondere nach dem Kaltstart der Brennkraftmaschine bis zum Erreichen der Betriebstemperatur durch insbesondere sehr unterschiedliche Temperaturen im Bereich des Abgasturboladers. Die schwingungsabsorbierende Auslegung bedämpft kleinste Wege bei höchsten Frequenzen, die durch die sehr hohen Drehzahlen der Turbine und des Rotors des Abgasturboladers hervorgerufen werden. Die erfindungsgemäße Abstützvorrichtung gewährleistet bei einer gewichtsreduzierten Auslegung der Tragvorrichtung und sonstiger Befestigungsteile eine erhöhte Betriebssicherheit der Brennkraftmaschine, wobei diese insbesondere einen Hubraum von mehr als zehn Liter pro Zylinder, beispielsweise als achtzylindrige Brennkraftmaschine einen Gesamthubraum von ca. 135 Litern, aufweist. Bei Brennkraftmaschinen solcher Größe ist die Erfindung besonders vorteilhaft anwendbar.These Task is solved by that a vibration-absorbing and length-adjustable support device provided between the exhaust gas turbocharger and the internal combustion engine is and that the support device is attached to the exhaust gas turbocharger away from the support device. With such a vibration-absorbing and length-adjustable Support device will damage safely avoided, with the support device designed so that no tension between the individual Components occur. The pioneering from the exhaust gas turbocharger attachment side the support device is on any housing part the internal combustion engine attached. This housing part, for example the Crankcase, a Cylinder head or a front cover of the internal combustion engine, is designed to absorb the introduced forces. The length adjustability allows the self-employed Adaptation to thermal expansion-related changes in length without a disability of expansion. Such thermal expansion-related changes in length arise in particular after the cold start of the engine until reaching the operating temperature by especially very different temperatures in the region of the exhaust gas turbocharger. The vibration-absorbing design dampens the smallest paths at highest frequencies, due to the very high speeds of the turbine and rotor Turbocharger be caused. The supporting device according to the invention guaranteed in a weight-reduced design of the support device and other fasteners increased reliability of Internal combustion engine, this particular a displacement of more as ten liters per cylinder, for example, as eight-cylinder internal combustion engine a total cubic capacity of approx. 135 liters. In internal combustion engines such size is the Invention particularly advantageous applicable.
In weiterer Ausgestaltung weist die Abstützvorrichtung ein Primär- und ein Sekundärteil auf, die längenverstellbar miteinander verbunden sind. Dabei umfasst in wiederum weiterer Ausgestaltung die Längenverstelleinrichtung ein Helix, das an dem Primärteil drehbar befestigt ist und in einem mit einer drehhemmenden Füllung versehenen Gehäuse angeordnet ist, das wiederum Teil des Sekundärteils ist. Diese Ausbildung hat sich besonders bewährt, wobei darauf hinzuweisen ist, dass ein hydraulisch wirkender Stoßdämpfer als Abstützvorrichtung ungeeignet, beispielsweise wegen des auftretenden Frequenzspektrums, ist.In In another embodiment, the supporting device has a primary part and a secondary part, the length adjustable connected to each other. This includes in turn further embodiment the length adjustment a helix attached to the primary part is rotatably mounted and provided in a with a rotation-inhibiting filling casing is arranged, which in turn is part of the secondary part. This training has proven particularly effective It should be noted that a hydraulic shock absorber as Support device unsuitable, for example due to the occurring frequency spectrum, is.
In Weiterbildung ist die Füllung ein Granulat, das bezüglich der Auswahl und der Größe der einzelnen Granulatkörner so ausgewählt ist, dass beim Zusammenwirken mit dem Helix insbesondere kein Verschleiß und keine Beschädigungen und umgekehrt eine Bewegung des Helix in dem Granulat möglich ist. Als Granulat sind beispielsweise Sand, Stahlkugeln, Wolframgranulat auch in Mischungen geeignet.In Continuing education is the filling a granulate that respects the selection and the size of the individual granules so selected is that when interacting with the helix in particular no wear and no damage and conversely, a movement of the helix in the granules is possible. As granules are, for example, sand, steel balls, tungsten granules also suitable in mixtures.
In weiterer Ausgestaltung kann das Gehäuse zusätzlich gekühlt sein, indem beispielsweise ein Kühlmittel, beispielsweise Wasser, Öl oder auch Luft, gezielt durch das Gehäuse oder aber durch einen Kühlmantel an dem Gehäuse (auch in Abhängigkeit der Art des Granulats) geleitet wird.In In another embodiment, the housing may additionally be cooled by, for example a coolant, for example water, oil or air, targeted through the housing or through a cooling jacket on the housing (also depending on Type of granules) is passed.
Schließlich kann das Helix zwischen zwei in dem Gehäuse angeordneten Druckfedern eingespannt sein. Die Druckfedern bewirken eine vordefinierbare, neutrale, mittlere Länge des Dämpfers bei äußerer Kraftfreiheit.Finally, can the helix between two compression springs arranged in the housing be clamped. The compression springs cause a predefinable, neutral, medium length of the damper with external freedom.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist der Zeichnungsbeschreibung zu entnehmen, in der ein in den Fig. dargestelltes Ausführungsbeispiel näher beschrieben ist.A further advantageous embodiment of the invention is the drawing description ent take in which an embodiment shown in the figures is described in more detail.
