Description
Die vorliegende Erfindung betrifft einen Schalldämpfer für eine Abgasanlage eines Fahrzeugs gemäß dem Oberbegriff des Patentanspruches 1 sowie ein Fahrzeug gemäß den Merkmalen des Patentanspruches 10.The present invention relates to a silencer for an exhaust system of a vehicle according to the preamble of claim 1 and a vehicle according to the features of claim 10.
Ein derartiger Schalldämpfer ist aus der
Schalldämpfer für Abgasanlagen weisen ein Gehäuse auf, wobei das Gehäuseinnere üblicherweise durch ein- oder mehrere in Längsrichtung des Gehäuses voneinander beabstandete Schottbleche in einzelne Gehäusekammern unterteilt ist. Die Gehäusekammern stehen über Durchgangsöffnungen bzw. Rohrabschnitte in Strömungsverbindung zueinander, so dass der Schalldämpfer von Abgas durchströmt werden kann. Aufeinanderfolgende Durchgangsöffnungen bzw. Rohrabschnitte sind versetzt zueinander angeordnet, so dass das Abgas beim Durchströmen des Schalldämpfers mehrmals seine Richtung ändern muss, wodurch sich der Schallpegel reduziert.Mufflers for exhaust systems have a housing, wherein the housing interior is usually divided by one or more spaced apart in the longitudinal direction of the housing partition plates into individual housing chambers. The housing chambers are in fluid communication with each other via passage openings or pipe sections, so that exhaust gas can flow through the muffler. Successive passage openings or pipe sections are arranged offset to one another, so that the exhaust gas must change its direction several times as it flows through the muffler, whereby the sound level is reduced.
Bei manchen Fahrzeugen ist der sogenannte „Endschalldämpfer” ganz hinten im Heckbereich des Fahrzeugs angeordnet und „quer” in Bezug auf die Fahrzeuglängsrichtung eingebaut. „Quer” bedeutet also, dass sich die Längsachse des Schalldämpfers parallel zu einer Querrichtung des Fahrzeugs erstreckt.In some vehicles, the so-called "rear muffler" is located at the very rear of the rear of the vehicle and installed "across" with respect to the vehicle longitudinal direction. Thus, "transverse" means that the longitudinal axis of the muffler extends parallel to a transverse direction of the vehicle.
Aufgabe der Erfindung ist es, einen Schalldämpfer, der für einen „Quereinbau” vorgesehen ist, „crashgünstig” zu gestalten.The object of the invention is to make a silencer, which is intended for a "transverse installation", "crash-priced".
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of claim 1. Advantageous embodiments and further developments of the invention can be found in the dependent claims.
Ausgangspunkt der Erfindung ist ein Schalldämpfer für eine Abgasanlage eines Fahrzeugs mit einem länglichen Gehäuse, welches einen Gehäusemantel und zwei Stirnwände aufweist, die im Wesentlichen senkrecht zu einer Längsachse des Gehäuses angeordnet sind. In dem Gehäuse ist mindestens ein „Schottelement” angeordnet, welches das Gehäuse in mindestens zwei Gehäusekammern unterteilt, die in Strömungsverbindung miteinander stehen. Das Schottelement kann durch ein Schottblech gebildet sein. Wenn im Folgenden von „Schottblech” die Rede ist, so ist dieser Begriff nicht unbedingt auf ein „Blech” beschränkt, sondern ganz allgemein im Sinne eines „Schottelements” zu interpretieren.The starting point of the invention is a silencer for an exhaust system of a vehicle having an elongated housing, which has a housing shell and two end walls, which are arranged substantially perpendicular to a longitudinal axis of the housing. At least one "bulkhead element" is arranged in the housing, which subdivides the housing into at least two housing chambers which are in fluid communication with one another. The bulkhead element may be formed by a partition plate. In the following, the term "bulkhead sheet metal" is mentioned, so this term is not necessarily limited to a "sheet metal", but rather to interpret in the sense of a "bulkhead element".
Der Kern der Erfindung besteht darin, dass das Gehäuse im Bereich des mindestens einen Schottblechs deformationsweich gestaltet ist. Dadurch unterscheidet sich die Erfindung grundlegend von der eingangs genannten
Bei Fahrzeugen mit quer eingebautem Endschalldämpfer kann es im Crashfall nämlich von Nachteil sein, wenn der Endschalldämpfer zu steif ist. Herkömmlich eingebaute Endschalldämpfer stellen im Crashfall einen vergleichsweise „massiven” Block dar, der kaum Deformationsenergie aufnehmen kann.In vehicles with transversely mounted rear silencer, it can be a disadvantage in the event of a crash, if the rear silencer is too stiff. Conventionally installed rear silencers provide a comparatively "massive" block in the event of a crash, which hardly absorbs any deformation energy.
Insbesondere bei Hybridfahrzeugen, bei denen vorderhalb des Endschalldämpfers ein Hochvoltspeicher angeordnet ist (aber auch bei herkömmlichen, d. h. „Nicht-Hybridfahrzeugen”), ist es jedoch von Vorteil, wenn der Endschalldämpfer energieabsorbierend konstruiert ist, d. h., wenn er sich im Crashfall deformieren kann und entsprechend Energie aufnehmen kann.However, in hybrid vehicles in particular, where a high-voltage accumulator is arranged in front of the rear silencer (but also in conventional, that is to say "non-hybrid vehicles"), it is advantageous if the rear silencer is designed to be energy-absorbing, i. h., If it can deform in the event of a crash and can absorb energy accordingly.
Nach einer Weiterbildung der Erfindung wird die „Deformationsweichheit” dadurch erreicht, dass das mindestens eine Schottblech nicht exakt senkrecht zur Längsachse des Schalldämpfergehäuses angeordnet ist, sondern schräg dazu, z. B. in einem Winkel zwischen 1° und 45°, vorzugsweise in einem Winkel zwischen 5° Grad und 30° Grad. Durch eine Schrägstellung des mindestens einen Schottblechs wird dessen Einknicken im Crashfall erleichtert.According to a development of the invention, the "deformation softness" is achieved in that the at least one partition plate is not arranged exactly perpendicular to the longitudinal axis of the muffler housing, but obliquely thereto, z. B. at an angle between 1 ° and 45 °, preferably at an angle between 5 ° and 30 ° degrees. By an inclination of the at least one partition plate whose buckling in the event of a crash is facilitated.
Alternativ oder ergänzend dazu kann vorgesehen sein, dass das mindestens eine Schottblech eine gezielt konstruktiv vorgesehene Schwächung oder Sollbruchstelle aufweist, welche bei einem Crash eine Deformation des Schottblechs, insbesondere ein Verbiegen bzw. Ausbeulen oder Einknicken des Schottblechs erleichtert.Alternatively or additionally, it may be provided that the at least one bulkhead plate has a deliberately designed weakening or predetermined breaking point, which facilitates a deformation of the bulkhead plate, in particular a bending or buckling or buckling of the bulkhead plate in the event of a crash.
Insbesondere kann vorgesehen sein, dass das Schottblech uneben gestaltet ist. Beispielsweise kann das Schottblech zick-zack-artig gestaltet sein, wodurch sich zusätzlich die Schallabsorption verbessert.In particular, it can be provided that the partition plate is uneven. For example, the partition plate may be zig-zag-shaped, which additionally improves the sound absorption.
Alterativ oder ergänzend dazu können in dem Schottblech eine Sicke oder eine Ausbeulung bzw. mehrere Sicken, Ausbeulungen, Erhebungen oder Vertiefungen vorgesehen sein.Alternatively or additionally, in the partition plate, a bead or a bulge or a plurality of beads, bulges, elevations or depressions may be provided.
Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen:In the following the invention will be explained in connection with the drawing. Show it:
