Abstract

The method involves providing a suitable isolator (1) between the filter (4) and the neighboring vehicle components in order to reduce the thermal radiation and/or thermal conduction to other vehicle components. Attachment elements are embedded in the isolator and further attachment elements connect the isolator to the surrounding vehicle components.

Description

Die vorliegende Erfindung betrifft die Befestigung eines Rußpartikelfilters in einem Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to the attachment of a particulate filter in a motor vehicle according to the preamble of claim 1

Nach dem Stand der Technik werden Rußpartikelfilter eingesetzt, um die Rußpartikel, die in den Abgasen eines Dieselmotors enthalten sind, zu sammeln und in vorgegebenen Zeit- oder Kilometerintervallen rückstandslos zu verbrennen. Sie sind üblicherweise am Getriebegehäuse befestigt bzw. verschraubt, können aber auch an anderen Fahrzeugbauteilen befestigt sein.To The prior art are particulate filters used to remove the soot particles, which are contained in the exhaust gases of a diesel engine and at predetermined time or kilometer intervals residue to burn. They are usually on the gearbox attached or screwed, can but also be attached to other vehicle components.

Rußpartikelfilter werden aufgrund ihrer Funktion sehr heiß und strahlen eine große Energiemenge bei hohen Temperaturen ab. Durch die Verschraubung z.B. an einem Getriebegehäuse wird die im Rußpartikelfilter entwickelte Wärme in nachteiliger Weise über die Befestigungseinrichtungen, beispielsweise Flansche, Befestigungsaugen und Laschen, auf das Getriebe bzw. auf andere Fahrzeugbauteile übertragen. Bei geringer Geschwindigkeit oder bei Stillstand des Fahrzeugs kommt noch eine zusätzliche Hitzestrahlung aufgrund mangelnder Fahrtluftkühlung dazu.Rußpartikelfilter become very hot due to their function and radiate a large amount of energy high temperatures. By screwing e.g. on a transmission housing in the soot particle filter developed heat disadvantageously about the fastening devices, such as flanges, fastening eyes and tabs, transmitted to the transmission or other vehicle components. At low speed or at standstill of the vehicle comes one more extra Heat radiation due to lack of drive air cooling.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Wärmeübertragung der in Rußpartikelfiltern entstehenden Wärme auf weitere Fahrzeugbauteile weitgehend zu reduzieren.Of the present invention is based on the object, the heat transfer in soot particle filters resulting heat To largely reduce to other vehicle components.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.

Demnach wird vorgeschlagen, zur Reduzierung der Wärmestrahlung bzw. Wärmeleitung vom Rußpartikelfilter auf andere Fahrzeugbauteile einen geeigneten Isolator zu verwenden. Hierbei wird der Isolator vorzugsweise zwischen dem Rußpartikelfilter und den benachbarten Fahrzeugbauteilen angeordnet.Therefore is proposed to reduce the heat radiation or heat conduction from the soot particle filter to use a suitable insulator on other vehicle components. Here, the insulator is preferably between the soot particle filter and arranged the adjacent vehicle components.

In vorteilhafter Weise eignet sich hierbei ein Isolator aus Keramik, Glas oder aus einem anderen hitzefesten, schlecht wärmeleitenden Material.In Advantageously, this is an insulator made of ceramic, Glass or another heat-resistant, poorly heat-conducting Material.

Gemäß einer besonders vorteilhaften Weiterbildung der Erfindung sind die Befestigungselemente des Rußpartikelfilters im Isolator eingebettet. Des weiteren sind zur Befestigung der auf diese Weise gebildeten Rußpartikelfilter-Isolator-Einheit am Fahrzeug weitere Befestigungselemente vorgesehen, die den Isolator mit den umliegenden Fahrzeugbauteilen verbinden, welche die Rußpartikelfilter-Befestigungselemente nicht berühren und den Isolator nicht durchdringen.According to one Particularly advantageous development of the invention are the fasteners of the soot particle filter embedded in the insulator. Furthermore, for fixing on This so formed particulate filter-insulator unit provided on the vehicle more fasteners that the insulator connect to the surrounding vehicle components, which are the soot particle filter fasteners do not touch and do not penetrate the insulator.

Der verwendete Isolator kann je nach Abstand und Anordnung des Rußpartikelfilters zu benachbarten Bauteilen aus mehreren Einzelteilen, Isolationsplatten oder auch ganzen Isolationskörpern bestehen.Of the used insulator may vary depending on the distance and arrangement of the particulate filter to neighboring components of several individual parts, insulation plates or even entire insulation bodies.

Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es stellen dar:The The invention will be explained in more detail below by way of example with reference to the attached figures. Put it represents:

1 eine perspektivische Darstellung der erfindungsgemäßen Befestigung eines Rußpartikelfilters in einem Kraftfahrzeug; und 1 a perspective view of the attachment according to the invention of a particulate filter in a motor vehicle; and

2 eine weitere perspektivische Darstellung der erfindungsgemäßen Befestigung eines Rußpartikelfilters gemäß 1. 2 a further perspective view of the attachment according to the invention of a particulate filter according to 1 ,

Wie den 1 und 2 zu entnehmen ist, ist gemäß der Erfindung ein Isolator 1 zwischen dem Rußpartikelfilter 4 und den benachbarten Fahrzeugbauteilen angeordnet. Hierbei sind die Befestigungselemente 3 des Rußpartikelfilters im Isolator 1 eingebettet. Erfindungsgemäß sind am Fahrzeug weitere Befestigungselemente 2 vorgesehen, die den Isolator 1 mit den umliegenden Fahrzeugbauteilen verbinden. Diese Befestigungselemente 2 berühren die Rußpartikelfilter-Befestigungselemente 3 nicht, so dass eine daraus resultierende Wärmeleitung vermieden wird.Like that 1 and 2 it can be seen, according to the invention, an insulator 1 between the soot particle filter 4 and the adjacent vehicle components. Here are the fasteners 3 of the soot particle filter in the insulator 1 embedded. According to the invention further fastening elements on the vehicle 2 provided the insulator 1 connect with the surrounding vehicle components. These fasteners 2 touch the soot particle filter fasteners 3 not, so that a resulting heat conduction is avoided.
