Abstract

The element is located between the housing sections and is tensioned on one of its end plates. The tensioned end plate is stiff and is fixed to the filter housing. The end plate pref. consists of a thermoplastic. The tensioned end plate pref. has a surrounding band section.

Description

Die Erfindung betrifft eine Luftfiltereinheit für eine Brennkraftmaschine gemäß dem Oberbegriff des Patentan­ spruchs 1. Die bisher in der Praxis verwendeten Luftfilter­ gehäuse weisen im Regelfall eine Verrippung auf, die das erforderliche Maß an Volumensteifigkeit und Schwingungs­ dämpfung gewährleistet. Dadurch soll insbesondere verhin­ dert werden, daß die Gehäusewandung des Luftfilters unter dem Einfluß der Ansaugpulsation schwingt.The invention relates to an air filter unit for a Internal combustion engine according to the preamble of the patent Proverb 1. The air filters previously used in practice housings usually have ribbing that the required degree of volume rigidity and vibration cushioning guaranteed. This should prevent in particular be changed that the housing wall of the air filter under the influence of the suction pulsation swings.

Diese Verrippung beansprucht jedoch ein bestimmtes Bauvolu­ men wodurch entweder - bei Innenverrippung - der Einbauraum des Filterelements oder - bei Außenverrippung - der Motor­ raum verkleinert wird.However, this ribbing takes up a certain amount of construction which either - with internal ribbing - the installation space the filter element or - in the case of external ribbing - the motor space is reduced.

Die Erfindung beschäftigt sich daher mit dem Problem, ein Luftfiltergehäuse zu versteifen ohne gleichzeitig den Bau­ raum für das Filterelement oder den Motorraum zu verklei­ nern.The invention is therefore concerned with the problem Stiffen air filter housing without building at the same time space for the filter element or the engine compartment nern.

Erfindungsgemäß wird das Problem mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst, wobei die Merkmale der Unteransprüche vorteilhafte Aus- und Weiterbildungen kenn­ zeichnen.According to the invention the problem with the characteristic Features of claim 1 solved, the features of Advantageous training and further education to draw.

Die Ausbildung der zwischen den Gehäuseteilen eingespannten Endscheibe des Filterelements als tragendes Teil im Filter­ gehäuse ermöglicht bei gleichbleibender Steifigkeit einen weitgehenden Wegfall der Verrippung des Filtergehäuses und beansprucht keinen zusätzlichen Bauraum.The formation of the clamped between the housing parts  End plate of the filter element as a supporting part in the filter housing enables a with the same rigidity extensive elimination of the ribbing of the filter housing and does not take up any additional installation space.

Verglichen mit einer Ausbildung der Endscheibe aus Elasto­ mer führt diese Konstruktion zu einer deutlichen Erhöhung der Steifigkeit des Filtergehäuses.Compared to an end plate made of elasto This construction leads to a significant increase the rigidity of the filter housing.

Die Krafteinleitung vom Filtergehäuse in die Endscheibe des Filterelements erfolgt vorzugsweise mit einem an der End­ scheibe zumindest teilweise umlaufenden Bund, der als Zen­ trierrahmen kraft- und formschlüssig in einer Nut des Fil­ tergehäuses liegt.The force transmission from the filter housing into the end plate of the Filter element is preferably made with one at the end slice at least partially encircling covenant, which is called Zen trier frame non-positively and positively in a groove of the fil tergehäuses lies.

Bei entsprechend enger Passung der anderen Endscheibe im Filtergehäuse mit punktueller Anlage der Endscheibe an meh­ reren Anlageflächen auf dem Umfang der Gehäusewand kann auch diese Endscheibe Trag- und Versteifungsfunktionen übernehmen. Dabei muß die Passung einerseits so weit ge­ wählt werden, daß das Filterelement noch montierbar ist und andererseits so eng, daß die Endscheibe permanent am Fil­ tergehäuse anliegt und Klappern vermieden wird.With a correspondingly tight fit of the other end plate in the Filter housing with selective contact of the end plate on meh reren contact surfaces on the circumference of the housing wall this end plate also supports and stiffening functions take over. The fit must on the one hand be so far ge be chosen that the filter element is still mountable and on the other hand so narrow that the end plate is permanently attached to the fil ters housing and rattling is avoided.

Die Erfindung wird im folgenden anhand eines Beispiels be­ schrieben. Es zeigtThe invention will be based on an example wrote. It shows

Fig. 1 ein Luftfiltergehäuse mit Filter­ element im Querschnitt. Fig. 1 is an air filter housing with filter element in cross section.

Ein Luftfilter 1 besteht aus einem Deckel 2 mit einem Aus­ laßstutzen 3 und einem Gehäuse 4 zur Aufnahme eines Filter­ elements 5. Das Filterelement 5 besitzt eine Endscheibe 6, mit der es zwischen Deckel 2 und Gehäuse 4 eingespannt ist. Die Endscheibe 6 besteht aus einem formsteifen Material und weist einen zumindest teilweise umlaufenden Bund 7 auf, der form- und kraftschlüssig in eine am Gehäuse angeformte Nut 8 greift. Eine Dichtung 9 trennt die Reinseite des Filters von der Umgebung. Das Einführen des Bunds 7 in die Nut 8 wird auf der Innenseite der Nut durch eine Fase und auf der Außenseite durch einzelne, angefaste Rippen 10 erleichtert.An air filter 1 consists of a cover 2 with an outlet nozzle 3 and a housing 4 for receiving a filter element 5 . The filter element 5 has an end plate 6 with which it is clamped between the cover 2 and the housing 4 . The end plate 6 is made of a dimensionally stable material and has an at least partially circumferential collar 7 which engages in a groove 8 formed on the housing in a form-fitting and non-positive manner. A seal 9 separates the clean side of the filter from the environment. The introduction of the collar 7 into the groove 8 is facilitated on the inside of the groove by a chamfer and on the outside by individual chamfered ribs 10 .
