Description
Die Erfindung betrifft eine Brennkraftmaschinenanordnung für ein Kraftfahrzeug mit zumindest einer Brennkraftmaschine und einer über eine Befestigungsanordnung damit verbundenen Abgasanlage, wobei die Befestigungsanordnung mindestens ein starres Halterorgan und mindestens eine Verbindungsanordnung mit einer Dämpfungsanordnung aufweist, wobei die Dämpfungsanordnung zumindest einen Dämpfungskörper mit einem damit verbunden Anlenkorgan aufweist.The invention relates to an internal combustion engine arrangement for a motor vehicle with at least one internal combustion engine and an exhaust system connected to it via a fastening arrangement, the fastening arrangement having at least one rigid holder element and at least one connection arrangement with a damping arrangement, the damping arrangement having at least one damping body with an articulation element connected thereto.
Eine derartige Brennkraftmaschinenanordnung ist aus der
Aufgabe der Erfindung ist es daher, den oben genannten Nachteil auf einfache und kostengünstige Weise zu vermeiden.The object of the invention is therefore to avoid the above-mentioned disadvantage in a simple and inexpensive manner.
Diese Aufgabe wird dadurch gelöst, dass das Anlenkorgan der mindestens einen Dämpfungsanordnung unmittelbar oder mittelbar mit der Brennkraftmaschine verbunden ist und der Dämpfungskörper unmittelbar oder mittelbar mit der Abgasanlage verbunden ist. Es hat sich nämlich herausgestellt, dass in einem bestimmten Drehzahlbereich die Abgasanlage zur Eigenresonanz angeregt wird. Dadurch, dass nun das Anlenkorgan der mindestens einen Dämpfungsanordnung unmittelbar oder mittelbar mit der Brennkraftmaschine verbunden ist, kann die Resonanzhöhe deutlich reduziert werden und die Eigenfrequenz verschoben werden.This object is achieved in that the articulation element of the at least one damping arrangement is connected directly or indirectly to the internal combustion engine and the damping body is connected directly or indirectly to the exhaust system. It has been found that the exhaust system is excited to self-resonance in a certain speed range. Because the articulation element of the at least one damping arrangement is now connected directly or indirectly to the internal combustion engine, the resonance level can be significantly reduced and the natural frequency shifted.
In einer besonders vorteilhaften Ausführungsform ist es vorgesehen, dass eine Dämpfungsrichtung der Dämpfungsanordnung in Richtung einer Kraftfahrzeughochachse verläuft. Hierdurch ist eine sehr kompakte Brennkraftmaschinenanordnung gewährleistet.In a particularly advantageous embodiment, it is provided that a damping direction of the damping arrangement runs in the direction of a vertical vehicle axis. This ensures a very compact internal combustion engine arrangement.
Der Dämpfungskörper ist in vorteilhafter Weise über Verbindungsmittel der Verbindunganordnung an einem Konverter, wie z.B. einem Abgaskatalysator, befestigt. Hierzu können die Verbindungsmittel eine Klemmlasche aufweisen, die an einem Befestigungshalter befestigt ist.The damping body is advantageously connected to a converter, e.g. a catalytic converter attached. For this purpose, the connecting means can have a clamping tab which is fastened to a fastening holder.
Das Anlenkorgan greift in vorteilhafter Weise auf einen Motorträger an, der wiederum an der Brennkraftmaschine, wie zum Beispiel am Zylinderkopf, angeordnet ist.The articulation member advantageously engages a motor mount, which in turn is arranged on the internal combustion engine, such as on the cylinder head.
Für eine einfache Montierbarkeit ist das Anlenkorgan als Stangenorgan ausgebildet, das an der der Brennkraftmaschine zugewandten Seite ein Gewinde aufweist. Dieses Gewinde greift dann zwecks Montage beispielsweise in ein Gewindeauge des Motorträgers.For easy assembly, the articulation element is designed as a rod element which has a thread on the side facing the internal combustion engine. This thread then engages, for example, in a threaded eye of the motor mount for the purpose of assembly.
Der Dämpfungskörper weist in vorteilhafter Weise mehrere Kissen auf, durch die das Anlenkorgan in Einfahr- sowie in Ausfahrrichtung druckbelastet ist, um eine Reduzierung der Kraft- und Amplitudengröße im beschriebenen Schwingungssystem zu gewährleisten. The damping body advantageously has a plurality of cushions through which the articulation element is pressure-loaded in the entry and exit directions in order to ensure a reduction in the force and amplitude magnitude in the described vibration system.
