Abstract

The invention relates to a hollow part (7, 11) of a chassis, running gear, or superstructure of a motor vehicle (1) that is driven by a combustion engine (4), whose exhaust gases are discharged into the atmosphere via an exhaust gas pipe assembly (12). Said part is characterised in that it is configured or positioned as an integral part of the exhaust gas pipe assembly.

Description

Hohlkammer- bzw. Strukturteil eines Kraftfahrzeuges Hollow chamber or structural part of a motor vehicle
Die Erfindung betrifft ein Hohlkammerteil bzw. ein Kavitäten aufweisendes Strukturteil eines Chassis, Fahrwerkes oder Aufbaus eines Kraftfahrzeuges, welches durch einen Verbrennungsmotor, dessen Abgase über einen Abgasstrang in die Atmosphäre abströmen, angetrieben wird bzw. antreibbar ist.The invention relates to a hollow part or a structural part of a chassis, undercarriage or body of a motor vehicle having cavities, which is driven or can be driven by an internal combustion engine, the exhaust gases of which flow into the atmosphere via an exhaust line.
Mechanisch belastbare Strukturteile sind an heutigen Kraftfahrzeugen regelmäßig als Hohlkammerteile ausgebildet, und zwar oftmals in Form von Schalenteilen. Auf diese Weise läßt sich eine hohe strukturelle Festigkeit bei vergleichsweise geringem Herstellungsaufwand erzielen.Structural parts that can withstand mechanical loads are regularly designed as hollow-chamber parts on today's motor vehicles, often in the form of shell parts. In this way, a high structural strength can be achieved with a comparatively low production cost.
Ein Beispiel für mechanisch belastbare Hohlkammerteile ist bei heutigen Fahrzeugen auch der Auspuffsträng, welcher trotz Belastungen durch Pulsationen und Vibrationen sowie korrodierende Bestandteile und vergleichsweise hohe Temperatur der Abgase regelmäßig eine lange Lebensdauer aufweist.An example of mechanically resilient hollow chamber parts in today's vehicles is also the exhaust line, which regularly has a long service life despite loads from pulsations and vibrations as well as corrosive components and comparatively high temperature of the exhaust gases.
Aufgabe der Erfindung ist es nun, eine weitere Rationalisierung zu ermöglichen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Hohlkammer- bzw. Strukturteil des Chassis, Fahrwerkes oder Aufbaus eines Kraftfahrzeuges als Teil des Abgasstranges ausgebildet oder angeordnet ist.The object of the invention is now to enable further rationalization. This object is achieved in that a hollow chamber or structural part of the chassis, chassis or body of a motor vehicle is designed or arranged as part of the exhaust line.
Die Erfindung beruht auf dem allgemeinen Gedanken, die Innenräume von an Fahrzeugen ohnehin am Fahrwerk, Chassis oder Fahrzeugaufbau vorhandenen Hohlräumen für den Abgasstrang heranzuziehen, so daß gesonderte Elemente für den Abgasstrang zumindest teilweise entfallen können. Dabei nutzt die Erfindung die Erkenntnis, daß die Abgase moderner Motoren mit hohem thermischen Wirkungsgrad vergleichsweise geringe Temperaturen haben und dementsprechend zu einer verminderten thermischen Belastung des Abgasstranges führen. Dies gilt insbesondere für Abgassysteme mit Stickoxid- Speicherkatalysatoren.The invention is based on the general idea of using the interiors of cavities for the exhaust system, which cavities are present on the chassis, chassis or vehicle structure, so that separate elements for the exhaust system can be at least partially eliminated. The invention uses the knowledge that the exhaust gases of modern engines with a high thermal efficiency have comparatively low temperatures and accordingly lead to a reduced thermal load on the exhaust system. This applies in particular to exhaust systems with nitrogen oxide storage catalysts.
Des weiteren bietet die Erfindung den Vorzug, daß vergleichsweise große Volumina für den Äbgasstrang zur Verfügung gestellt werden können, mit der Folge, daß ein weites Geräuschspektrum, insbesondere auch Geräusche mit tiefen Frequenzen, gut gedämpft werden können.Furthermore, the invention offers the advantage that comparatively large volumes can be made available for the exhaust gas line, with the result that a wide spectrum of noise, in particular also noise with low frequencies, can be damped well.
Im übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine besonders bevorzugte Ausführungsform der Erfindung näher beschrieben wird. Dabei zeigt die einzige Figur eine schematisierte Draufsicht auf ein Kraftfahrzeug, bei dem Hohlkammer-Strukturteile im Abgasstrang des den Fahrzeug antreibenden Verbrennungsmotors angeordnet sind.For the rest, with regard to preferred features of the invention, reference is made to the claims and the following explanation of the drawing, on the basis of which a particularly preferred embodiment of the invention is described in more detail. The single figure shows a schematic plan view of a motor vehicle in which hollow-chamber structural parts are arranged in the exhaust line of the internal combustion engine driving the vehicle.
Ein nur schematisch dargestelltes Kraftfahrzeug 1 besitzt vordere lenkbare Räder 2 und hintere angetriebene Räder 3. Der Antrieb erfolgt mittels eines Verbrennungsmotors 4 und einen nur schematisiert und strichliert dargestellten Antriebstrang 5.A motor vehicle 1, which is only shown schematically, has front steerable wheels 2 and rear driven wheels 3. The drive takes place by means of an internal combustion engine 4 and a drive train 5, which is only shown schematically and in broken lines.
Die angetriebenen Räder 3 sind in grundsätzlich bekannter Weise über Radführungslenker 6 an einen vom nicht dargestellten Fahrzeugaufbau gesonderten Hilfsrahmen 7 angebunden, welcher als Hohlkam er-Schalenteil ausgebildet ist.The driven wheels 3 are connected in a generally known manner via wheel guide links 6 to a subframe 7 which is separate from the vehicle body (not shown) and which is designed as a hollow chamber shell part.
Des weiteren besitzt das Fahrzeug 1 vordere und hintere Stoßfänger 8 und 9, die mit der nicht näher dargestellten Fahrzeugtragstruktur, beispielsweise eine selbsttragende Karosserie, über vordere und hintere Pralltöpfe 10 und 11 verbunden ist. Bei einer Kollision des Fahrzeuges können die Stoßfänger 8 bzw. 9 unter irreversibler Verformung der Pralltöpfe 10 und 11 nachgeben, so daß zumindest bei leichteren Kollisionen schwerwiegende Schäden an der Tragstruktur des Fahrzeuges vermieden werden können und letztendlich nur Stoßfänger 8,9 und Pralltöpfe 10 bzw. 11 ausgetauscht werden müssen. Auch die Pralltöpfe 10 und 11 können in grundsätzlich bekannter Weise als Hohlkammer-Schalenteile ausgebildet sein.Furthermore, the vehicle 1 has front and rear bumpers 8 and 9, which are connected to the vehicle support structure (not shown in more detail), for example a self-supporting body, via front and rear impact pots 10 and 11. In the event of a collision of the vehicle, the bumpers 8 and 9 can yield under irreversible deformation of the impact pots 10 and 11, so that, at least in the event of minor collisions, serious damage to the supporting structure of the vehicle can be avoided, and ultimately only bumpers 8, 9 and impact pots 10 or 11 need to be replaced. The baffles 10 and 11 can also be designed in a generally known manner as hollow-chamber shell parts.
Erfindungsgemäß ist nun vorgesehen, die vom Hilfsrahmen 7 und/oder dem hinteren großen Pralltopf 11 gebildeten Hohlkammern zur Geräuschdämpfung in einen Abgasstrang 12 des' Verbrennungsmotors 4 einzubinden.According to the invention, it is now provided to integrate the hollow chambers formed by the auxiliary frame 7 and / or the rear large baffle 11 for noise reduction into an exhaust line 12 of the ' internal combustion engine 4.
Die vom Hilfsrahmen 7 bzw. vom Pralltopf 11 gebildeten Hohlkammern können beispielsweise nach Art von Resonatorkammern an den Abgasstrang 12 angeschlossen sein.The hollow chambers formed by the auxiliary frame 7 or by the baffle 11 can be connected to the exhaust line 12, for example, in the manner of resonator chambers.
Vorzugsweise werden die Abgasleitungen des Abgasstranges 12 zumindest teilweise durch Metallschläuche, beispielsweise in Form von Wellschläuchen, gebildet, wie in der Zeichnung schematisch angegeben ist. Auf diese Weise kann die Übertragung von Vibrationen im Abgasstrang 12 vermindert werden. The exhaust pipes of the exhaust line 12 are preferably at least partially formed by metal hoses, for example in the form of corrugated hoses, as is shown schematically in the drawing. In this way, the transmission of vibrations in the exhaust line 12 can be reduced.
