Description
Technisches GebietTechnical area
Die Erfindung betrifft ein Gehäuse für eine Kurbelgehäuseentlüftungsvorrichtung mit wenigstens einem Einlassstutzen und einem dazu axial versetzt angeordneten Auslassstutzen.The The invention relates to a housing for a crankcase ventilation device with at least one inlet port and one axially offset arranged outlet.
Stand der TechnikState of the art
Die Bauräume für Motorbauteile sind oft sehr unterschiedlich und begrenzt. Daher muss die Winkelposition von Einlass- und Auslassstutzen bei einem bekannten Gehäuse für eine Kurbelgehäuseentlüftungsvorrichtung, auch Kurbelgehäuseentlüftungs-System (KGE-System) genannt, oftmals konstruktiv angepasst werden, um die Anschlussleitungen im gegebenen Bauraum verlegen zu können. Bisher werden Gehäusevarianten über gesonderte Werkzeuge hergestellt, die aber nur bei großen Serienstückzahlen rentabel sind, oder durch Wechseleinsätze in Spritzgusswerkzeugen, die einige verschiedene Positionen der Anschlüsse zulassen. Die Anzahl der Varianten ist jedoch stark durch die Entformungsrichtung im Werkzeug und den Werkzeugaufbau selbst begrenzt.The installation spaces for engine components are often very different and limited. Therefore, the angular position must be inlet and outlet ports in a known housing for a crankcase ventilation device, also crankcase ventilation system (KGE system), often adapted constructively to the To be able to lay connecting cables in the given installation space. So far Housing variants are via separate tools produced, but only with large serial numbers profitable, or through inserts in injection molds, which allow several different positions of the connections. The number of Variants is however strong due to the demoulding direction in the tool and limits the tool structure itself.
Aufgabe der Erfindung ist es daher, am Gehäuse einer Kurbelgehäuseentlüftungsvorrichtung verschiedene Winkelstellungen von Ein- zu Auslassstutzen in einfacher und kostengünstiger Weise vorsehen zu können.task The invention is therefore different on the housing of a crankcase ventilation device Angle positions from inlet to outlet in simpler and cheaper Way to provide.
Offenbarung der ErfindungDisclosure of the invention
Diese Aufgabe wird durch ein Gehäuse für eine Kurbelgehäuseentlüftungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a housing for one Crankcase ventilation device solved with the features of claim 1.
Durch die Verschnappung der beiden Gehäuseteile ist es möglich, diese bei der Fertigung in einer nahezu beliebigen Winkelstellung zueinander zu positionieren. Der in der Rastverbindung eingeschlossene Dichtring ermöglicht eine gasdichte sowie temperatur- und ölbeständige Verbindung. Dadurch, dass ein durchgängiger Rastring vorgesehen ist, sind zwar erhebliche Fügekräfte erforderlich; diese können bei der Herstellung des Gehäuses jedoch durch Pressen aufgebracht werden, wenn die zu fügenden Module entsprechend in Haltevorrichtungen positioniert sind. Im späteren Einsatz ist dann aber aufgrund der hohen Klemmkräfte ein unbeabsichtigtes Verdrehen oder gar Lösen der Ringschnappverbindung ausgeschlossen.By the snapping of the two housing parts Is it possible, These in the production in almost any angular position to position each other. The trapped in the locking connection Sealing ring allows a gastight, temperature and oil resistant connection. Thereby, that one continuous Rastring is provided, although significant joining forces are required; These can be added the manufacture of the housing however, be applied by pressing when the modules to be joined are positioned accordingly in holding devices. In later use But then due to the high clamping forces an unintentional twisting or even solve it excluded the ring snap connection.
Vorzugsweise ist an dem Rastringabsatz und/oder an dem Rastaufnahmeabsatz eine sich in eine Trennebene zwischen den Gehäuseteilen erstreckende Aufnahmenut für den Dichtring vorgesehen. Damit ist es insbesondere möglich, den Dichtring vor der Fügung der Gehäuseteile vorzumontieren, indem der Dichtring in die Aufnahmenut eingelegt wird.Preferably is at the locking ring shoulder and / or at the locking receiving shoulder a extending into a parting plane between the housing parts receiving groove for the Provided sealing ring. This makes it possible in particular, the Sealing ring before joining the housing parts vorzumontieren by the sealing ring inserted into the receiving groove becomes.
Durch die Aufnahmenut wird ein Aufnahmeraum für den Dichtring mit einer definierten Geometrie geschaffen. Besonders bevorzugt ist eine Ausführungsform, bei der der Grund der Aufnahmenut schräg in Bezug auf eine Trennebene zwischen den Gehäuseteilen angestellt ist. Am gegenüberlie genden Absatz des jeweils anderen Gehäuseteils ist eine gleichartig orientierte Schrägfläche ausgebildet, dass heißt, eine Ringfläche, die im Wesentlichen parallel zum Nutgrund der Dichtungsaufnahmenut ausgerichtet ist.By the receiving groove is a receiving space for the sealing ring with a defined Geometry created. Particularly preferred is an embodiment at the bottom of the receiving groove obliquely with respect to a parting plane between the housing parts is employed. On the opposite Paragraph of the other housing part is formed a similar oriented inclined surface, that is, a Ring surface, the substantially parallel to the groove bottom of the Dichtungsaufnahmenut is aligned.
Durch
diese Schrägstellung
wird Folgendes bewirkt:
Beim Fügen der Gehäuseteile erfolgt eine axiale
Bewegung des Rastringabsatzes auf den Rastaufnahmeabsatz zu. Die
dabei aufgebrachten axialen Kräfte erzeugen
eine Verpressung des O-Ringes quer zur Kraftrichtung. Durch die
Schrägstellung
der Nut bietet die Nut genügend
Platz zur Aufnahme des verpressten O-Ringes, ohne die Verbindungsgeometrie zu
verbreitern. Durch die dabei aufzubringenden axialen Kräfte entsteht
an den Schrägflächen auch
eine radiale Kraftkomponente, durch welche der Dichtungsring nach
außen
bewegt und entsprechend vorgespannt wird. Hierdurch können Toleranzen
im Durchmesser des Dichtrings leicht ausgeglichen werden.This skew causes:
When joining the housing parts takes place an axial movement of the locking ring paragraph on the locking receiving shoulder. The applied axial forces generate a compression of the O-ring transverse to the direction of force. Due to the inclination of the groove, the groove provides enough space to accommodate the compressed O-ring, without widening the connection geometry. Due to the axial forces to be applied thereto, a radial force component, by means of which the sealing ring is moved outwards and correspondingly prestressed, is also produced on the inclined surfaces. As a result, tolerances in the diameter of the sealing ring can be easily compensated.
Der weitere Vorteil der schrägen Ausbildung des Nutgrundes liegt darin, dass der Übergang vom Rastringabsatz bzw. Rastaufnahmeabsatz zur normalen Wandstärke des Moduls tiefer heruntergezogen werden kann, da eine ausreichend große Wandstärke oberhalb der Dichtungsaufnahmenut bestehen bleibt, um die Festigkeit des entsprechenden Wandungsbereichs zu gewährleisten.Of the further advantage of the oblique Formation of the groove bottom is that the transition from the locking ring paragraph or Rastaufnahmeabsatz down to the normal wall thickness of the module pulled down can be because a sufficiently large wall thickness above the Dichtungsaufnahmenut persists to the strength of the corresponding wall area to ensure.
Vorzugsweise gehen die Rastringlasche und der Rastaufnahmeabsatz an der hergestellten Rastverbindung bündig ineinander über, sodass keine Überstände oder sonstige Angriffspunkte gegeben sind, an denen ein Aushebeln der Gehäuseverbindungen möglich wäre. Es wird damit vermieden, dass benutzerseitig in den Aufbau des Gehäuses der Kurbelgehäuseentlüftungsvorrichtung eingegriffen wird.Preferably go the locking tab and the locking receptacle paragraph of the manufactured Flush connection flush into each other, so no supernatants or Other attack points are given, where a leveraging the housing connections possible would. It is thus avoided that the user side in the construction of the housing of the crankcase ventilation device is intervened.
