Abstract

A compact drive for the timing adjusters in an IC engine has one of the adjusters (2) driven off the crankshaft (3, 4) by a chain or belt drive (5) and the other adjuster (1) driven directly off the first adjuster via meshing gear wheels. This provides a compact drive with easy maintenance access. Each adjuster comprises a hydraulically controlled rotor and stator design with the rotors rigidly fitted to the inlet or outlet camshaft. The chain/belt drive wheel is axially spaced from the meshing gears for improved access.

Description

Die Erfindung betrifft eine Nockenwellenverstelleinrichtung für Brennkraftmaschinen von Kraftfahrzeugen nach dem Oberbegriff des Anspruches 1.The invention relates to a camshaft adjusting device for internal combustion engines of motor vehicles according to the preamble of claim 1.

Nockenwellenverstelleinrichtungen dienen dazu, bei Brennkraftmaschinen von Kraftfahrzeugen den Öffnungszeitpunkt der Einlaßventile in Abhängigkeit vom Leistungsbedarf der Brennkraftmaschine zu steuern. Hierzu sind ein Einlaßnockenwellenversteller 1 (Fig. 2) und/oder ein Auslaßnockenwellenversteller 2 vorgesehen, die über eine endlos umlaufende Kette 5 mit einer Kurbelwelle 3 antriebsverbunden sind. Die Nockenwellenversteller 1, 2 haben jeweils einen Stator, in dem relativ drehbar ein Rotor untergebracht ist, der auf der jeweiligen Nockenwelle 12, 29 drehfest sitzt. Die Rotoren werden mit Druckmedium beaufschlagt, wenn sie relativ zum Stator gedreht werden sollen. Die Statoren der beiden Nockenwellenversteller 1, 2 sind jeweils mit einem Antriebsrad 6, 6' versehen, über das die Kette 5 geführt ist. Bei beengten Einbauverhältnissen ist es schwierig und teilweise auch nicht möglich, die Kette 5 zu montieren.Camshaft adjusting devices are used in internal combustion engines of motor vehicles to control the opening time of the intake valves as a function of the power requirement of the internal combustion engine. For this purpose, an intake camshaft adjuster 1 (FIG. 2) and / or an exhaust camshaft adjuster 2 are provided, which are drive-connected to a crankshaft 3 via an endlessly circulating chain 5. The camshaft adjusters 1, 2 each have a stator in which a rotor is relatively rotatably accommodated, which rotatably seated on the respective camshaft 12, 29. The rotors are pressurized with media when they are to be rotated relative to the stator. The stators of the two camshaft adjusters 1, 2 are each provided with a drive wheel 6, 6 'over which the chain 5 is guided. In cramped installation conditions, it is difficult and sometimes not possible to mount the chain 5.

Ähnliche Nockenwellenverstelleinrichtungen sind aus der EP-A-1 156 191, der EP-A-1 013 899 und der EP-A-0 624 717 bekannt.Similar camshaft adjusting devices are known from EP-A-1 156 191, EP-A-1 013 899 and EP-A-0 624 717.

Darüber hinaus sind Nockenwellenantriebsvorrichtungen bekannt, bei denen die Nockenwellen über ein Zahnradgetriebe miteinander antriebsverbunden sind, während eine dieser Nockenwellen über einen Endlostrieb von der Kurbelwelle angetrieben wird (US-A-4 610 224, DE 100 01 066 A, EP-A-0 420 290, EP-A-0 740 053).In addition, camshaft drive devices are known in which the camshafts are drive-connected to one another via a toothed gearing, while one of these camshafts is driven by the crankshaft via an endless drive (US Pat. No. 4,610,224, DE 100 01 066 A, EP-A-0 420,290, EP-A-0 740 053).

Bei der gattungsgemäßen Nockenwellenverstelleinrichtung (US-B-6 244 230) wird eine Nockenwelle über einen Endlostrieb von der Kurbelwelle angetrieben. Über ein Zahnradgetriebe wird eine zweite Nockenwelle drehbar angetrieben. Die Zahnräder sowie das Antriebsrad für den Endlostrieb liegen jeweils an einem Ende der Nockenwellen, so daß die entsprechenden Antriebszüge mit erheblichem Abstand voneinander vorgesehen sind und in das Kraftfahrzeug eingebaut werden müssen. Für beengte Einbauverhältnisse ist diese Einrichtung nicht geeignet.In the generic camshaft adjusting device (US Pat. No. 6,244,230), a camshaft is driven by the crankshaft via an endless drive. Via a gear transmission, a second camshaft is rotatably driven. The gears and the drive wheel for the Endlostrieb are each at one end of the camshaft, so that the corresponding drive trains are provided at a considerable distance from each other and must be installed in the vehicle. For cramped installation conditions, this device is not suitable.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Nockenwellenverstelleinrichtung so auszubilden, daß sie auch bei beengten Einbauverhältnissen einfach eingebaut werden kann.The invention has the object of providing the generic camshaft adjusting so that they can be easily installed even in confined spaces.

Diese Aufgabe wird bei der gattungsgemäßen Nockenwellenverstelleinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic camshaft adjusting device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Nockenwellenverstelleinrichtung sind die beiden Nockenwellenversteller über das Zahnradgetriebe miteinander antriebsverbunden. Das Antriebsrad des einen Nockenwellenverstellers läßt sich lagebestimmt bequem montieren, wobei auch bei beengten Einbauverhältnissen das endlos umlaufende Antriebselement einfach montiert werden kann. Das Antriebsrad liegt axial benachbart zum Zahnrad und ist mit ihm verbunden, so daß die beiden Antriebszüge nebeneinander angeordnet sind und somit nur wenig Bauraum in Anspruch nehmen.In the case of the camshaft adjusting device according to the invention, the two camshaft adjusters are drive-connected to one another via the gearwheel transmission. The drive wheel of a camshaft adjuster can be mounted in a positionally convenient manner, whereby even in cramped installation conditions, the endlessly revolving drive element can be easily mounted. The drive wheel is axially adjacent to the gear and is connected to it, so that the two drive trains are arranged side by side and thus take up little space to complete.

Die beiden Nockenwellenversteller haben jeweils einen Stator, der einen Rotor umgibt, der relativ zum Stator drehbar ist und auf der jeweiligen Nockenwelle drehfest sitzt. Die Rotoren der Nockenwellenversteller können durch Druckmedium in der gewünschten Richtung relativ zum Stator verstellt werden, um auf diese Weise den Öffnungszeitpunkt der Einlaßventile der Brennkraftmaschine zu verändern.The two camshaft adjusters each have a stator surrounding a rotor which is rotatable relative to the stator and rotatably seated on the respective camshaft. The rotors of the camshaft adjusters can be adjusted by pressure medium in the desired direction relative to the stator, so as to change the opening timing of the intake valves of the internal combustion engine in this way.

Bei einer ersten Ausführungsform sind die Nockenwellenversteller über ihre Zahnräder unmittelbar miteinander im Eingriff. In diesem Falle ist die Kurbelwelle lediglich mit dem einen Nockenwellenversteller über den Endlosantrieb verbunden.In a first embodiment, the camshaft adjuster are directly engaged with each other via their gears. In this case, the crankshaft is connected only to the one camshaft adjuster via the endless drive.

Bei einer zweiten Ausführungsform greifen die Zahnräder der beiden Nokkenwellenversteller in ein gemeinsames Zahnrad ein, das drehfest auf einer Zwischenwelle sitzt. Sie ist ihrerseits über den Endlostrieb mit der Kurbelwelle antriebsverbunden. In diesem Fall wird die Zwischenwelle über den Endlostrieb drehbar angetrieben, wodurch über das Zahnradgetriebe die Nockenwellenversteller angetrieben werden.In a second embodiment, the gears of the two Nokkenwellenversteller engage in a common gear, which sits non-rotatably on an intermediate shaft. It is in turn drive-connected to the crankshaft via the endless drive. In this case, the intermediate shaft is rotatably driven via the endless drive, whereby the camshaft adjuster are driven via the gear transmission.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.

Die Nockenwellenverstelleinrichtung gemäß den Fig. 1 und 3 bis 5 hat den Einlaßnockenwellenversteller 1 und den Auslaßnockenwellenversteller 2. Auf der Kurbelwelle 3 sitzt drehfest ein Kettenrad 4, das über die Kette 5 mit dem Kettenrad 6 des Auslaßnockenwellenverstellers 2 antriebsverbunden ist. Das Kettenrad 6 kann einspurig oder zweispurig ausgebildet sein. Wie die Fig. 3 bis 5 zeigen, ist das Kettenrad 6 im Ausführungsbeispiel zweispurig ausgebildet und weist dementsprechend zwei Zahnkränze 7 und 8 auf. Das Kettenrad 6 ist über ein Distanzglied 9 mit einem Zahnkranz 10 verbunden, der vorteilhaft einstückig mit dem Stator 11 verbunden ist. Er umgibt in bekannter Weise den Rotor, der drehfest auf der Auslaßnockenwelle 12 sitzt. Wie Fig. 3 zeigt, hat der Stator 11 einen zylindrischen Mantel 13, der den Zahnkranz 10 axial überragt und der wenigstens eine in Achsrichtung verlaufende Vertiefung 14 aufweist, die im Ausführungsbeispiel teilkreisförmigen Querschnitt hat. In diese Vertiefung 14 greift formschlüssig ein entsprechender Vorsprung 15 ein, der an der Innenseite des Kettenrades 6 vorgesehen ist. Über die Vertiefung 14 und den Vorsprung 15 erfolgt die radiale Ausrichtung des Kettenrades 6 gegenüber dem Stator 11, der Teil des Nockenwellenverstellers 2 ist. Auf den Mantel 13 werden das Distanzglied 9 und das Kettenrad 2 aufgeschoben. Anschließend werden das Distanzglied 9 und das Kettenrad 6 mit Schrauben 16 mit dem Stator 11 und dem Zahnkranz 10 verbunden.The camshaft adjusting device according to FIGS. 1 and 3 to 5 has the intake camshaft adjuster 1 and the exhaust camshaft adjuster 2. The crankshaft 3 is rotatably mounted on a chain wheel 4, which is drive-connected via the chain 5 to the sprocket wheel 6 of the exhaust camshaft adjuster 2. The sprocket 6 may be formed single track or two lanes. As shown in FIGS. 3 to 5, the sprocket 6 is formed in the embodiment of two lanes and accordingly has two sprockets 7 and 8. The sprocket 6 is connected via a spacer 9 with a sprocket 10, which is advantageous is integrally connected to the stator 11. He surrounds the rotor in a known manner, which sits non-rotatably on the exhaust camshaft 12. As shown in FIG. 3, the stator 11 has a cylindrical jacket 13, which projects axially beyond the toothed rim 10 and which has at least one recess 14 extending in the axial direction, which in the exemplary embodiment has a part-circular cross-section. In this recess 14 engages positively a corresponding projection 15, which is provided on the inside of the sprocket 6. About the recess 14 and the projection 15, the radial alignment of the sprocket 6 relative to the stator 11, which is part of the camshaft adjuster 2. On the jacket 13, the spacer 9 and the sprocket 2 are pushed. Subsequently, the spacer 9 and the sprocket 6 are connected by screws 16 to the stator 11 and the ring gear 10.

Der Zahnkranz 10 hat größeren innendurchmesser als der Mantel 13 des Stators 11. Von der Innenseite des Zahnkranzes 10 stehen über den Umfang gleichmäßig verteilt Stege 17 ab, die den Zahnkranz 10 mit dem Statormantel 13 verbinden. Die Stege 17 haben Gewindebohrungen 18, in die die Schrauben 16 geschraubt werden.The ring gear 10 has a larger inner diameter than the shell 13 of the stator 11. From the inside of the ring gear 10 are distributed over the circumference uniformly distributed webs 17, which connect the ring gear 10 with the stator shell 13. The webs 17 have threaded holes 18 into which the screws 16 are screwed.

Das Distanzglied 9 weist über den Umfang verteilt vorgesehene Verdickungen 19 auf, die über beide Seiten des Distanzgliedes 9 ragen und jeweils eine Öffnung 20 für den Durchtritt der Schrauben 16 aufweisen.The spacer 9 has distributed over the circumference provided thickenings 19 which protrude beyond both sides of the spacer member 9 and each having an opening 20 for the passage of the screws 16.

Das Kettenrad 6 hat einen inneren umlaufenden Flansch 21, der etwa in halber Breite des Kettenrades 6 vorgesehen ist und über den Umfang verteilt angeordnete Öffnungen 22 für den Durchtritt der Schrauben 16 aufweist. Da der Flansch 21 gegenüber den Stirnseiten des Kettenrades 6 zurückgesetzt ist, liegen die Köpfe 23 der Schrauben 16 vertieft im Kettenrad 6 (Fig. 4). Das Distanzglied 9 hält das Kettenrad 6 auf axialem Abstand zum Zahnkranz 10.The sprocket 6 has an inner circumferential flange 21, which is provided approximately in half the width of the sprocket 6 and distributed over the circumference arranged openings 22 for the passage of the screws 16. Since the flange 21 is set back from the end faces of the sprocket 6, the heads 23 of the screws 16 are recessed in the sprocket 6 (Figure 4). The spacer 9 holds the sprocket 6 at an axial distance from the sprocket 10th

An der dem Kettenrad 6 zugewandten Stirnseite des Statormantels 13 ist eine Deckscheibe 24 (Fig. 4) mit Schrauben 25 befestigt. Die Deckscheibe 24 sichert in bekannter Weise den drehfest auf der Nockenwelle 12 (Fig. 1) sitzenden Rotor axial. An der gegenüberliegenden Stirnseite des Mantels 13 des Stators 11 ist eine Ringscheibe 26 mit Schrauben 27 befestigt, welche den Rotor in der anderen axialen Richtung im Stator 11 sichert.At the sprocket 6 facing end side of the stator shell 13 is a cover plate 24 (Fig. 4) secured with screws 25. The cover plate 24 secures in a known manner the rotatably on the camshaft 12 (Fig. 1) seated rotor axially. On the opposite end face of the jacket 13 of the stator 11, an annular disc 26 is fastened with screws 27, which secures the rotor in the other axial direction in the stator 11.

Die Kette 5 der Nockenwellenverstelleinrichtung ist über das Kettenrad 6 geführt (Fig. 1). Der Zahnkranz 10 greift in einen Zahnkranz 28 des Einlaß-Nockenwellenverstellers 1 ein (Fig. 1), der mit dem Stator drehfest verbunden, vorzugsweise einstückig mit ihm ausgebildet ist. Vorteilhaft haben die Zahnkränze 10, 28 gleichen Durchmesser.The chain 5 of the camshaft adjusting device is guided over the sprocket 6 (FIG. 1). The sprocket 10 engages in a ring gear 28 of the intake camshaft adjuster 1 (FIG. 1), which is rotatably connected to the stator, preferably integrally formed with it. Advantageously, the sprockets 10, 28 have the same diameter.

Da der Einlaßnockenwellenversteller 1 und der Auslaßnockenwellenversteller 2 über die Zahnkränze 10, 28 unmittelbar miteinander im Eingriff sind, können die beiden Nockenwellen 12, 29 mit geringem Abstand nebeneinander angeordnet sein. Dadurch läßt sich die Nokkenwellenverstelleinrichtung bei beengten Einbauverhältnissen einfach montieren, da der Kettentrieb lediglich zwischen dem Zahnrad 4 auf der Kurbelwelle 3 und dem Zahnrad 6 des Nockenwellenverstellers 2 vorgesehen ist.Since the intake camshaft adjuster 1 and the Auslaßnockenwellenversteller 2 via the sprockets 10, 28 are directly engaged with each other, the two camshafts 12, 29 may be arranged side by side with a small distance. As a result, the Nokkenwellenverstelleinrichtung can be mounted easily in cramped installation conditions, since the chain drive is provided only between the gear 4 on the crankshaft 3 and the gear 6 of the camshaft adjuster 2.

Das Kettenrad 6 läßt sich in der beschriebenen Weise einfach auf dem Statormantel 13 befestigen. Die Kurbelwelle 3 ist über die Kette 5 mit der Nockenwelle 12 verbunden, die ihrerseits über das Zahnradgetriebe 10, 28 mit der Nockenwelle 29 antriebsverbunden ist. Der Zahnkranz 10 und das Kettenrad 6 können aus unterschiedlichen Materialien hergestellt sein, so daß eine optimale Anpassung im Material dieser Teile im Hinblick auf den Einsatzfall möglich ist.The sprocket 6 can be easily mounted on the stator shell 13 in the manner described. The crankshaft 3 is connected via the chain 5 with the camshaft 12, which in turn is drivingly connected via the gear transmission 10, 28 with the camshaft 29. The sprocket 10 and the sprocket 6 may be made of different materials, so that an optimal adaptation in the material of these parts in view of the application is possible.

Bei der Ausführungsform gemäß Fig. 6 sind der Einlaßnockenwellenversteller 1 und der Auslaßnockenwellenversteller 2 nicht unmittelbar über die Zahnkränze 10, 28 miteinander in Eingriff. Die Nockenwellenverstelleinrichtung hat eine Zwischenwelle 30, die parallel zur Kurbelwelle 3 bzw. den Nockenwellen 12, 29 liegt und ein Zahnrad 31 drehfest trägt, das mit den Zahnkränzen 10, 28 der beiden Nockenwellenversteller 1, 2 in Eingriff ist. Auf der Zwischenwelle 30 sitzt außerdem drehfest ein Kettenrad 32 für die Kette 5. Die Kurbelwelle 3 treibt somit über den Kettentrieb 4, 5, 32 die Zwischenwelle 30 an, die ihrerseits über das Zahnrad 31 die Nockenwellenversteller 1, 2 in der beschriebenen Weise antreibt. Die Zahnräder 31 und 10, 28 haben vorteilhaft gleichen Durchmesser. Es ist aber auch möglich, daß das Zahnrad 31 einen anderen Durchmesser als die Zahnkränze 10, 28 hat, so daß je nach Durchmesserverhältnis eine Über- oder Untersetzung möglich ist.In the embodiment of FIG. 6, the intake camshaft adjuster 1 and the exhaust camshaft adjuster 2 are not engaged with each other directly via the sprockets 10, 28. The camshaft adjusting device has an intermediate shaft 30, which is parallel to the crankshaft 3 and the camshafts 12, 29 and rotatably carries a gear 31 which is in engagement with the sprockets 10, 28 of the two camshaft adjusters 1, 2. The crankshaft 3 thus drives via the chain drive 4, 5, 32, the intermediate shaft 30, which in turn drives the camshaft adjuster 1, 2 in the manner described via the gear 31. The gears 31 and 10, 28 advantageously have the same diameter. But it is also possible that the gear 31 has a different diameter than the sprockets 10, 28, so that depending on the diameter ratio over- or reduction is possible.

Auch diese Ausführungsform zeichnet sich dadurch aus, daß sie bei beengten Einbauverhältnissen einfach montiert werden. Der Kettentrieb ist lediglich zwischen dem Zahnrad 4 auf der Kurbelwelle 3 und dem Zahnrad 31 auf der Zwischenwelle 30 vorgesehen.This embodiment is characterized in that they are easily mounted in confined spaces. The chain drive is only provided between the gear 4 on the crankshaft 3 and the gear 31 on the intermediate shaft 30.
