In modernen Brennkraftmaschinen werden Vorrichtungen zur variablen Einstellung der Steuerzeiten von Gaswechselventilen eingesetzt, um die Phasenrelation zwischen Kurbelwelle und Nockenwelle in einem definierten Winkelbereich, zwischen einer maximalen Früh- und einer maximalen Spätposition, variabel gestalten zu können. Die Vorrichtung ist drehfest mit einer Nockenwelle verbunden und weist mehrer Druckkammern auf mittels derer durch Druckmittelzufuhr, bzw. -abfuhr eine Phasenrelation zwischen der Kurbelwelle und der Nockenwelle gezielt verändert werden kann. Die Druckmittelzufuhr zu und die Druckmittelabfuhr von den Druckkammern wird mittels eines Steuerventils gesteuert.In modern internal combustion engines devices for variable adjustment of the timing of gas exchange valves are used to make the phase relation between the crankshaft and camshaft in a defined angular range, between a maximum early and a maximum late position variable. The device is non-rotatably connected to a camshaft and has a plurality of pressure chambers by means of which by pressure medium supply, or -abfuhr a phase relation between the crankshaft and the camshaft can be selectively changed. The pressure medium supply to and the pressure medium discharge from the pressure chambers is controlled by means of a control valve.
Eine Vorrichtung und ein Steuerventil sind beispielsweise aus der
Die Nockenwelle ist mittels mehrerer Nockenwellenlager in einem Zylinderkopf der Brennkraftmaschine gelagert. Über eines der Nockenwellenlager wird einem in der Nockenwelle ausgebildeten Druckmittelkanal Druckmittel zugeführt, welches über ein Steuerventil, das in einer Aufnahme der Nockenwelle angeordnet ist, in die Druckkammern geleitet werden kann.The camshaft is supported by a plurality of camshaft bearing in a cylinder head of the internal combustion engine. Via one of the camshaft bearing, a pressure medium channel formed in the camshaft pressure medium is supplied, which can be passed via a control valve which is arranged in a receptacle of the camshaft in the pressure chambers.
Das Steuerventil besteht aus einem Ventilgehäuse und einem in dem Ventilgehäuse axial verschiebbar aufgenommenen Steuerkolben. Der Steuerkolben kann mittels einer elektromagnetischen Stelleinheit gegen die Kraft eines Federelements in axialer Richtung relativ zu dem Ventilgehäuse positioniert und somit die Druckmittelströme gesteuert werden.The control valve consists of a valve housing and an axially slidably received in the valve housing control piston. The control piston can be positioned by means of an electromagnetic actuator against the force of a spring element in the axial direction relative to the valve housing and thus the pressure medium flows are controlled.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Steuerventil anzugeben, wobei dessen Montageaufwand verringert werden soll.The present invention has for its object to provide a control valve, the assembly cost to be reduced.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass an einer Innenmantelfläche der Aufnahme eine Ringnut ausgebildet ist, in die der Sicherungsring eingreifen kann, wobei der Sicherungsring an einer axialen Seitenfläche des Ventilgehäuses anliegt und wobei an dem Ventilgehäuse zumindest ein Formschlusselement ausgebildet ist, mittels dem der Sicherungsring an dem Ventilgehäuse befestigt ist. Drüber hinaus kann vorgesehen sein, dass das Formschlusselement an der axialen Seitenfläche des Ventilgehäuses, an der der Sicherungsring anliegt, ausgebildet ist.The object is achieved in that on an inner circumferential surface of the receptacle an annular groove is formed, into which the retaining ring can engage, wherein the retaining ring rests against an axial side surface of the valve housing and wherein at least a positive locking element is formed on the valve housing, by means of which the retaining ring is attached to the valve housing. In addition, it can be provided that the positive-locking element on the axial side surface of the valve housing, against which the retaining ring is formed.
Der Sicherungsring dient zur Befestigung des Steuerventils in der Aufnahme, die beispielsweise innerhalb der Nockenwelle oder des Innenrotors ausgebildet sein kann. Das Steuerventil ist somit radial innerhalb der Vorrichtung positioniert. Der Sicherungsring ist als elastisch verformbares Bauteil ausgeführt, welches in radialer Richtung elastisch gestaucht und vergrößert werden kann, so dass dessen Durchmesser unter Krafteinwirkung aus dem Ruhezustand verkleinert und vergrößert werden kann. Entfällt die Kraft kehrt der Sicherungsring in seinen ursprünglichen Zustand zurück.The circlip is used to attach the control valve in the receptacle, which may be formed for example within the camshaft or the inner rotor. The control valve is thus positioned radially inside the device. The locking ring is designed as an elastically deformable component, which can be elastically compressed and enlarged in the radial direction, so that its diameter can be reduced and increased under the action of force from the idle state. If the force fails, the retaining ring returns to its original state.
Während der Montage des Steuerventils in der Aufnahme wird der Durchmesser des Sicherungsrings bei Eintritt in die Aufnahme durch deren Wandung in radialer Richtung gestaucht. Gelangt der Sicherungsring in den Bereich der Ringnut der Aufnahme rastet dieser in die Ringnut ein. Gleichzeitig liegt dieser in axialer Richtung an dem Ventilgehäuse, beispielsweise an einer axialen Seitenfläche des Ventilgehäuses, an, so dass die axiale Position des Ventilgehäuses und damit des Steuerventils in der Aufnahme festgelegt ist.During assembly of the control valve in the receptacle, the diameter of the securing ring is compressed when entering the receptacle by the wall in the radial direction. If the circlip arrives in the region of the annular groove of the receptacle, it engages in the annular groove. At the same time, this is in the axial direction of the valve housing, for example on an axial side surface of the valve housing, so that the axial position of the valve housing and thus of the control valve is fixed in the receptacle.
Durch die formschlüssige Verbindung des Sicherungsrings mit dem Ventilgehäuse kann das Steuerventil inklusive Sicherungsring als Baugruppe an die Montagelinie geliefert werden. Während der Montage des Steuerventils in der Aufnahme muss nur noch eine Baugruppe montiert werden und nicht zwei separate Bauteile. Darüber hinaus wird sichergestellt, dass bei der Montage der Sicherungsring verbaut wird.Due to the positive connection of the locking ring with the valve housing, the control valve including retaining ring can be delivered as an assembly to the assembly line. During assembly of the control valve in the receptacle only one assembly must be mounted and not two separate components. In addition, it is ensured that the circlip is installed during assembly.
In einer Weiterbildung der Erfindung kann vorgesehen sein, dass im Bereich der Seitenfläche des Ventilgehäuses, an der der Sicherungsring anliegt, zwei in Umfangsrichtung beabstandete, hakenförmige Formschlusselemente ausgebildet sind, die radial nach außen offen ausgebildet sind und den Sicherungsring in axialer Richtung hintergreifen, so dass der Sicherungsring sowohl an der axialen Seitenfläche des Ventilgehäuses als auch an sich radial erstreckenden Abschnitten der hakenförmigen Formschlusselemente anliegt. Somit ist die radiale Beweglichkeit des Sicherungsrings sichergestellt, wodurch die Montage weiter vereinfacht wird. Die hakenförmigen Strukturen halten den Sicherungsring an dessen vorbestimmter Position, wobei ein radiales Einfedern während der Montage ermöglicht wird. Die Montage des Sicherungsrings an dem Ventilgehäuse erfolgt dadurch, dass der Sicherungsring zunächst in radialer Richtung unter Vergrößerung dessen Durchmessers elastisch aufgebogen und in die Haken eingelegt wird. Anschließend wird die Krafteinwirkung, die zu der Vergrößerung des Durchmessers geführt hat, beendet und der Sicherungsring kehrt in seinen Ursprungszustand zurück, so dass dieser verliersicher in den Haken aufgenommen wird.In a further development of the invention it can be provided that in the region of the side surface of the valve housing, against which the retaining ring, two circumferentially spaced, hook-shaped form-locking elements are formed, which are designed to be radially outwardly open and engage behind the retaining ring in the axial direction, so that the locking ring bears against both the axial side surface of the valve housing and at radially extending portions of the hook-shaped positive locking elements. Thus, the radial mobility of the locking ring is ensured, whereby the assembly is further simplified. The hook-shaped structures hold the retaining ring at its predetermined position, wherein a radial compression during assembly is possible. The mounting of the locking ring on the valve housing is effected in that the securing ring is first bent elastically in the radial direction enlarging the diameter and inserted into the hook. Subsequently, the force, which has led to the increase in the diameter, terminated and the retaining ring returns to its original state, so that it is captive absorbed in the hook.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Sicherungsring einen sich radial nach innen erstreckenden Abschnitt aufweist, der als Axialanschlag für den Steuerkolben dient. Dadurch werden die innerhalb des Ventilgehäuses angeordneten Bauteile, wie Steuerkolben, Federelement und gegebenenfalls zwischen dem Ventilgehäuse und dem Steuerkolben angeordnete Hülsen, gegen Verlieren gesichert, so dass das gesamte Steuerventil als eine Baugruppe an die Montagelinie geliefert und verbaut werden kann.In an advantageous development of the invention it is provided that the retaining ring has a radially inwardly extending portion which serves as an axial stop for the control piston. Thereby, the arranged within the valve housing components, such as control piston, spring element and possibly arranged between the valve housing and the control piston sleeves are secured against loss, so that the entire control valve can be delivered as an assembly to the assembly line and installed.

Das Antriebselement 14 ist mittels radial innen liegender Umfangswände der Vorsprünge 22 relativ zu dem Abtriebselement 16 drehbar auf diesem gelagert.Starting from an outer
An einer äußeren Mantelfläche des ersten Gehäuses 15 ist ein Kettenrad 23 ausgebildet, über das mittels eines nicht dargestellten Kettentriebs Drehmoment von der Kurbelwelle 2 auf das Antriebselement 14 übertragen werden kann. Das Abtriebselement 16 weist eine Zentralöffnung 13 auf, die von der Nockenwelle 6,7 durchgriffen wird. Dabei ist das Abtriebselement 16 mittels einer Presspassung drehfest an der Nockenwelle 6, 7 befestigt.On an outer circumferential surface of the first housing 15, a
Innerhalb der Vorrichtung 11 ist zwischen jeweils zwei in Umfangsrichtung benachbarten Vorsprüngen 22 ein Druckraum 28 ausgebildet. Jeder der Druckräume 28 wird in Umfangsrichtung von gegenüberliegenden, im Wesentlichen radial verlaufenden Begrenzungswänden benachbarter Vorsprünge 22, in axialer Richtung von den Seitendeckeln 17, 18, radial nach innen von dem Nabenelement 19 und radial nach außen von der Umfangswand 21 begrenzt. In jeden der Druckräume 28 ragt ein Flügel 20, wobei die Flügel 20 derart ausgebildet sind, dass diese sowohl an den Seitendeckeln 17, 18, als auch an der Umfangswand 21 anliegen. Jeder Flügel 20 teilt somit den jeweiligen Druckraum 28 in zwei gegeneinander wirkende Druckkammern 29, 30.Within the
Durch Druckbeaufschlagung einer Gruppe von Druckkammern 29, 30 und Druckentlastung der anderen Gruppe kann die Phasenlage des Antriebselements 14 zum Abtriebselement 16 und damit die Phasenlage der Nockenwelle 6, 7 zur Kurbelwelle 2 variiert werden. Durch Druckbeaufschlagung beider Gruppen von Druckkammern 29, 30 kann die Phasenlage konstant gehalten werden.By pressurizing a group of
Die Druckmittelversorgung der Vorrichtung 11 erfolgt über das Innere der Nockenwelle 6, 7, die in der dargestellten Ausführungsform hohl ausgeführt ist, und ein in einer Aufnahme 31 der Nockenwelle 6, 7 angeordnetes Steuerventil 12.The pressure medium supply of the
An dem Ventilgehäuse 34 sind ein radialer Zulaufanschluss P, zwei radiale Arbeitsanschlüsse A, B und ein axialer Ablaufanschluss T ausgebildet. Der Ablaufanschluss T ist als axiale Öffnung an dem Ventilgehäuse 34 ausgebildet. Die Arbeitsanschlüsse A, B sind als radiale Öffnungen an der Mantelfläche des Ventilgehäuses 34 ausgebildet, wobei jeder der Arbeitsanschlüsse A, B über in dem Abtriebselement 16 ausgebildete Druckmittelkanäle 46 mit einer Gruppe von Druckkammern 29, 30 kommuniziert. Der Zulaufanschluss P ist ebenfalls als radiale Öffnung an der Mantelfläche des Ventilgehäuses 34 ausgebildet, wobei dieser in Umfangsrichtung versetzt zu den Arbeitsanschlüssen A, B angeordnet und als Langloch ausgebildet ist (
Das Ventilgehäuse 34 ist innerhalb der Nockenwelle 6, 7 angeordnet, wobei dessen axiale Position durch eine an der Innenmantelfläche der Nockenwelle 6, 7 und der Außenmantelfläche des Ventilgehäuses 34 ausgebildeten Schulter und einen Sicherungsring 42 festgelegt wird. Der Sicherungsring 42 überragt das Ventilgehäuse 34 in radialer Richtung, ist in einer Ringnut 44, die an der Innenmantelfläche der Nockenwelle 6, 7 ausgebildet ist, angeordnet und liegt an einer axialen Seitenfläche 43 des Ventilgehäuses 34 an.The
Innerhalb des Ventilgehäuses 34 ist die Hülse 35 angeordnet, deren Außendurchmesser dem Innendurchmesser des Ventilgehäuses 34 angepasst ist. Die Hülse 35 weist mehrere Öffnungen 37 auf, wobei jede der Öffnungen 37 mit einem der Arbeitsanschlüsse A, B oder dem Zulaufanschluss P kommuniziert.Within the
Innerhalb der Hülse 35 ist der Steuerkolben 36 axial verschiebbar aufgenommen. Der Steuerkolben 36 weist zwei Steuerabschnitte 38 auf, deren Außendurchmesser dem Innendurchmesser der Hülse 35 angepasst sind. Zwischen den Steuerabschnitten 38 ist eine ringförmig um den Steuerkolben 36 umlaufende Nut 39 vorgesehen.Within the
Der Steuerkolben 36 kann mittels einer nicht dargestellten elektromagnetischen Stelleinheit, welche auf das der Nockenwelle 6, 7 abgewandte Ende des Steuerkolbens 36 wirkt, gegen die Kraft eines Federelements 40 in axialer Richtung relativ zu dem Ventilgehäuse 34 positioniert werden. Das Federelement 40 ist in einer an dem Ventilgehäuse 34 ausgebildeten Federaufnahme 41 angeordnet und stützt sich einerseits an der Federaufnahme 41 und andererseits an Steuerkolben 36 ab. Dabei wird der Weg des Steuerkolbens 36 in axialer Richtung einerseits durch die Federaufnahme 41 und andererseits durch sich radial nach innen erstreckende Abschnitte 45 des Sicherungsrings 42 begrenzt (
Abhängig von der Stellung des Steuerkolbens 36 relativ zu dem Ventilgehäuse 34 ist einer der Arbeitsanschlüsse A, B mit dem Zulaufanschluss P verbunden, wobei gleichzeitig der andere Arbeitsanschluss A, B direkt oder über das Innere des Steuerkolbens 36 mit dem Ablaufanschluss T verbunden ist. Dabei sind an den Steuerabschnitten 38 des Steuerkolbens 36 und den Öffnungen 37 der Hülse 35 Steuerkanten ausgebildet, mittels derer die Druckmittelströme gesteuert werden.Depending on the position of the
Während des Betriebs der Brennkraftmaschine 1 wird von einer nicht dargestellten Druckmittelpumpe dem Inneren der Nockenwelle 6, 7 über Nockenwellenöffnungen 48 Druckmittel zugeführt. Das Druckmittel gelangt durch das Filterelement 47, über die nicht dargestellte Axialöffnung in dem Ventilgehäuse 34 und das Federblech 33 zu dem Zulaufanschluss P und von dort in einen ringförmigen Raum, der von der an dem Steuerkolben 36 ausgebildeten Nut 39 und der Hülse 35 begrenzt wird.During operation of the internal combustion engine 1, pressure medium is supplied to the interior of the camshaft 6, 7 via
Abhängig von der Stellung des Steuerkolbens 36 relativ zu dem Ventilgehäuse 34 wird das Druckmittel zu den ersten oder den zweiten Druckkammern 29, 30 geleitet. Gleichzeitig gelangt Druckmittel von den anderen Druckkammern 29, 30 über den Ablaufanschluss T zu einem nicht dargestellten Druckmittelreservoir der Brennkraftmaschine 1. Dadurch erfolgt eine Veränderung der Phasenlage des Abtriebselements 16 relativ zu dem Antriebselement 14 und damit der Nockenwelle 6, 7 relativ zur Kurbelwelle 2. Ist die gewünschte Phasenlage erreicht verschiebt die nicht dargestellte elektromagnetische Stelleinheit den Steuerkolben 36 in eine Neutralstellung, in der beiden Gruppen von Druckkammern 29, 30 Druckmittel zugeführt wird, so dass die relative Phasenlage konstant gehalten wird.Depending on the position of the
An der axialen Seitenfläche 43 an der der Sicherungsring 42 anliegt sind zwei in Umfangsrichtung beabstandete hakenförmige Formschlusselemente 49 ausgebildet, die radial nach außen offen ausgeführt sind. Jedes der Formschlusselemente 49 erstreckt sich ausgehend von der Seitenfläche 43 zunächst in axialer Richtung und weist einen sich daran anschließenden radialen Abschnitt 50 auf. Die Formschlusselemente 49 hintergreifen den Sicherungsring 42 in axialer Richtung, so dass dieser zwischen der axialen Seitenfläche 43 und den radialen Abschnitten 50 verliersicher aufgenommen wird. Während der Montage des Steuerventils 12 wird zunächst die Hülse 35, das Federelement 40 und der Steuerkolben 36 innerhalb des Ventilgehäuses 34 positioniert. Anschließend wird der geschlitzte Sicherungsring 42 mittels einer in Umfangsrichtung gerichteten Kraft elastisch aufgebogen und an der Seitenfläche 43 positioniert. Anschließend wird die Krafteinwirkung beendet, so dass der Sicherungsring 42 seine ursprüngliche Form kleineren Durchmessers wieder einnimmt und somit an dem Ventilgehäuse 34 befestigt ist. Auf Grund der sich radial nach innen erstreckenden Abschnitte 45 sind sowohl die Hülse 35 als auch der Steuerkolben 36 und damit das Federelement 40 verliersicher in dem Ventilgehäuse 34 aufgenommen, so dass das gesamte Steuerventil 12 als Baugruppe an die Montagelinie geliefert werden kann, ohne dass ein Verlust von Bauteilen zu befürchten ist.On the
Während der Montage des Steuerventils 12 in der Nockenwelle 6, 7 wird das Steuerventil 12 in diese eingeschoben, bis die Schulter des Ventilgehäuses 34 an der Schulter der Nockenwelle 6, 7 zur Anlage kommt. Dabei wird der Sicherungsring 42 beim Eintritt in die Nockenwelle 6, 7 elastisch gestaucht. Im Bereich der Ringnut 44 weitet sich der Sicherungsring 42 auf und greift selbsttätig in diese ein, so dass die axiale Position des Steuerventils 12 innerhalb der Nockenwelle 6, 7 festgelegt ist. Neben der einfachen Montage des Steuerventils 12 in der Nockenwelle 6, 7 besteht ein Vorteil des erfindungsgemäßen Steuerventils 12 in Einsteckbauweise darin, dass dieses als Modul an die Montagelinie geliefert werden kann ohne dass ein Verlust eines der Bauteile Steuerkolben 36, Federelement 40, Sicherungsring 42, Hülse 35 zu befürchten ist.During assembly of the
Die vorgestellten Ventilgehäuse 34 können einteilig oder mehrteilig ausgebildet sein. Im Fall von Ventilgehäusen 34, die aus mehreren sich axial erstreckenden Teilabschnitten mit sich in Umfangsrichtung gegenüberstehenden offenen Enden ausgebildet sind, ist vorzugsweise an jedem der Teilabschnitte ein Formschlusselement 49 ausgebildet, so dass die Teilabschnitte ebenfalls durch den Sicherungsring 42 relativ zueinander gesichert werden.The presented
Die Ventilgehäuse 34 können beispielsweise aus Stahl, Aluminium oder Kunststoff gefertigt sein.
