Abstract
Abgasanlage für ein Kraftfahrzeug, die mit einem eine Wärmeschildvorrichtung umfassenden Schalldämpfer an Aufbaustrukturen eines Aufbaus anschließt, dadurch gekennzeichnet, dass die Wärmeschutzschildvorrichtung (15) einen Wärmeschutzmantel (16) und ein Wärmeschutzgehäuse (17) umfasst, wobei der Wärmschutzmantel (16; 21) den Schalldämpfer (13; 27) unmittelbar umgibt und das nach Art eines Kastens ausgebildete Wärmeschutzgehäuse (17) zumindest bereichsweise mit Abstand (Asl, Asll und Aslll) zum Wärmeschutzmantel (16; 21) des Schalldämpfers (13; 27) verläuft.exhaust system for a Motor vehicle, with a silencer comprising a heat shield device Construction structures of a structure connects, characterized that the heat shield device (15) a heat jacket (16) and a thermal protection housing (17) comprising, wherein the thermal protection jacket (16; 21) the muffler (13; 27) immediately surrounding and formed in the manner of a box heat protection housing (17) at least in certain areas with distance (Asl, Asll and Aslll) to the heat protection jacket (16; 21) of the muffler (13; 27).
Description
Die Erfindung bezieht sich auf eine Abgasanlage für ein Kraftfahrzeug nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an exhaust system for a motor vehicle after Preamble of claim 1.
Es
ist eine Abgasanlage eines Fahrzeugs bekannt,
Die
Es ist Aufgabe der Erfindung eine Wärmeschildvorrichtung für eine Abgasanlage so auszubilden, dass eine an die Abgasanlage angrenzende bspw. aus nicht metallischem Werkstoff bestehende Aufbaustruktur eines Aufbaus funktionsgerecht vor Strahlungswärme der Abgasanlage geschützt ist.It The object of the invention is a heat shield device for one Design exhaust system so that an adjacent to the exhaust system eg. of non-metallic material existing structure of a Structure is functionally protected against radiant heat of the exhaust system.
Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüche enthalten.To The invention achieves this object by the features of the patent claim 1 solved. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass dank der einen Wärmeschutzmantel und ein Wärmeschutzgehäuse aufweisenden Wärmeschutzschildvorrichtung der Abgasanlage bspw. nicht metallische oder aus Kunststoff bestehende Aufbaustrukturen eines Kraftfahrzeugs wirkungsvoll vor einem erhebliche Wärme abstrahlendem Schalldämpfer dieser Abgasanlage geschützt sind. Durch diese Wärmeschutzschildvorrichtung wird auch die freie Gestaltung des Kraftfahrzeugs gerade im Bereich des Schalldämpfers unterstützt, da letzterer auch relativ nahe an Aufbaustrukturen heranführbar ist. Der Wärmeschutzmantel ist aufgrund der Wärmedämmmatte gut wirksam, wobei besagte Wärmedämmmate an einer Tragschale gehalten ist, die auf einfache Weise mittels Stützelementen von Halteelementen des Schalldämpfers getragen wird. Schließlich trägt die Belüftungseinrichtung der Wärmeschutzschildvorrichtung zu einer gezielten Abfuhr der Strahlwärme des Schalldämpfers bei.The with the invention mainly The advantages that can be achieved are the fact that thanks to a heat protection jacket and a heat protection housing having Heat shield device the exhaust system, for example. Non-metallic or made of plastic Structure of a motor vehicle effectively before a significant Heat radiating silencer protected by this exhaust system are. Through this heat shield device is also the free design of the motor vehicle in the area of the muffler support since the latter is also relatively close to building structures be approached. The heat protection jacket is due to the thermal insulation mat good effective, said heat insulation rate a tray is held in a simple manner by means of support elements of holding elements of the muffler will be carried. After all wears the aerator the heat shield device to a targeted removal of the radiant heat of the muffler.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert wird.In The drawing is an embodiment of the invention, which is explained in more detail below.
