Description

Die Erfindung betrifft eine elektromagnetische Verstelleinrichtung gemäß dem Oberbegriff des Patentanspruchs 1 sowie die Verwendung einer elektromagnetischen Verstelleinrichtung für eine Nockenwellenverstellung einer Brennkraftmaschine eines Fahrzeugs gemäß dem Oberbegriff des Patentanspruchs 3.The invention relates to an electromagnetic adjusting device according to the preamble of patent claim 1 and the use of an electromagnetic adjusting device for a camshaft adjustment of an internal combustion engine of a vehicle according to the preamble of patent claim 3.

Ein hydraulischer Nockenwellenversteller für eine Brennkraftmaschine eines Fahrzeugs umfasst eine elektromagnetische Verstelleinrichtung zur Betätigung eines Steuerventils des hydraulischen Nockenverstellers, wobei die elektromagnetische Verstelleinrichtung wenigstens eine Magnetspule mit einem Spulenkern und einen zur Betätigung des Steuerventils relativ zur Nockenwelle in deren axialer Richtung verschiebbaren Anker aufweist.A hydraulic camshaft adjuster for an internal combustion engine of a vehicle comprises an electromagnetic adjusting device for actuating a control valve of the hydraulic cam phaser, wherein the electromagnetic adjusting device comprises at least one solenoid having a coil core and an armature for actuating the control valve relative to the cam shaft in the axial direction.

Es sind elektromagnetische Verstelleinrichtungen für Nockenwellenversteller bekannt, welche zur Betätigung des Steuerventils zwei Magnetspulen vorsehen. Des Weiteren sind auch elektromagnetische Verstelleinrichtungen mit lediglich einer einzigen Magnetspule bekannt.There are known electromagnetic adjustment for camshaft adjuster, which provide for actuation of the control valve two magnetic coils. Furthermore, electromagnetic adjustment devices with only a single magnetic coil are known.

Um Verstelleinrichtungen für Nockenwellenversteller mittels eines Motorsteuergerätes zu steuern, werden diese mit einem Stecker ausgerüstet, über den die Verstelleinrichtung an das Motorsteuersystem angeschlossen werden kann. Ein solcher Stecker muss bei einer Verstelleinrichtung mit zwei Magnetspulen wenigstens drei Steckerkontakte für den Anschluss der beiden Magnetspulen aufweisen, wie dies schematisch in Figur 3 dargestellt ist.In order to control adjusting devices for camshaft adjusters by means of a motor control unit, they are equipped with a plug, via which the adjusting device can be connected to the engine control system. Such a plug must have at least three plug contacts for the connection of the two magnetic coils in an adjustment device with two magnetic coils, as shown schematically in FIG FIG. 3 is shown.

Diese Figur 3 zeigt eine elektromagnetische Verstelleinrichtung 100 für Nockenwellenversteller mit zwei Magnetspulen M1 und M2 eines Aktuators, wobei jede dieser Magnetspulen einen ersten und zweiten Anschluss A11 und A12 bzw. A21 und A22 aufweist. Die beiden Magnetspulen M1 und M2 sind innerhalb der Verstelleinrichtung 100 in Serie geschaltet. So ist der erste Anschluss A11 der ersten Magnetspule M1 auf einen ersten Steckerkontakt K11 geführt ist; der zweite Anschluss A12 ist mit dem zweiten Anschluss A22 der zweiten Magnetspule M2 zusammengeführt und bildet einen dritten Steckerkontakt K13. Der erste Anschluss A21 der zweiten Magnetspule M2 bildet den zweiten Steckerkontakt K12. Zur Bestromung der Serienschaltung der beiden Magnetspulen M1 und M2 wird entweder an den ersten Steckerkontakt K11 oder an den zweiten Steckerkontakt K12 der positive Pol einer Betriebsspannungsquelle angelegt, während an den dritten Steckerkontakt K13 der negative Pol der Betriebsspannung angelegt wird. Diese Steckerkontakte K11, K12 und K13 bilden gegebenenfalls zusammen mit weiteren Steckerkontakten einen Stecker SK dieser Verstelleinrichtung 100. Je nachdem, ob an dem ersten oder zweiten Steckerkontakt K11 bzw. K12 der positive Pol der Betriebsspannungsquelle angelegt wird, wird eine unterschiedliche Bestromungsrichtung des Stromes durch die beiden Magnetspulen M1 und M2 eingestellt.These FIG. 3 shows an electromagnetic adjustment device 100 for camshaft adjuster with two magnetic coils M1 and M2 of an actuator, each of these magnetic coils having a first and second terminals A11 and A12 and A21 and A22. The two magnetic coils M1 and M2 are connected in series within the adjusting device 100. Thus, the first terminal A11 of the first magnetic coil M1 is guided on a first plug contact K11; the second terminal A12 is connected to the second terminal A22 of the second solenoid M2 and forms a third plug contact K13. The first terminal A21 of the second magnetic coil M2 forms the second plug contact K12. To energize the series connection of the two magnetic coils M1 and M2, the positive pole of an operating voltage source is applied either to the first plug contact K11 or to the second plug contact K12, while the negative pole of the operating voltage is applied to the third plug contact K13. Depending on whether the positive pole of the operating voltage source is applied to the first or second plug contact K11 or K12, a different current application direction of the current is generated by the plug-in contacts K11, K12 and K13 set both magnetic coils M1 and M2.

Bei einer Verstelleinrichtung mit lediglich einer einzigen Magnetspule sind dagegen lediglich zwei Steckerkontakte erforderlich. Dies zeigt eine schematisch in Figur 2 dargestellte Verstelleinrichtung 10 mit einer einzigen Magnetspule M eines Aktuators mit einem ersten Anschluss A und einem zweiten Anschluss B, die jeweils an einen Steckerkontakt K1 und K2 geführt sind. Diese beiden Steckerkontakte bilden gegebenenfalls mit weiteren Steckerkontakten einen Stecker S der Verstelleinrichtung 10.In an adjustment with only a single solenoid, however, only two plug contacts are required. This shows a schematic in FIG. 2 illustrated adjustment device 10 with a single solenoid M of an actuator with a first terminal A and a second terminal B, which are each guided to a plug contact K1 and K2. These two plug contacts optionally form a plug S of the adjusting device 10 with further plug contacts.

Im Vergleich zur Verstelleinrichtung 100 benötigt die Verstelleinrichtung 10 einen Steckerkontakt weniger. Daher muss in Abhängigkeit der Verstelleinrichtung die jeweilige passende Buchse bereitgestellt werden. Eine "Steckerkompatibilität" zwischen diesen beiden Ausführungen von Verstelleinrichtungen 10 und 100 besteht nicht.In comparison to the adjusting device 100, the adjusting device 10 requires a plug contact less. Therefore, the respective matching socket must be provided depending on the adjustment. A "plug compatibility" between these two versions of adjusting 10 and 100 does not exist.

Der Erfindung liegt daher die Aufgabe zugrunde, die eingangs genannte elektromagnetische Verstelleinrichtung mit einer einzigen Magnetspule derart weiterzuentwickeln, dass ein Stecker verwendbar ist, der zu demjenigen Stecker einer elektromagnetischen Verstelleinrichtung mit zwei Magnetspulen kompatibel ist.The invention is therefore based on the object, the aforementioned electromagnetic adjustment with a single solenoid such that a plug can be used, which is compatible with the plug of an electromagnetic adjustment with two magnetic coils.

Diese Aufgabe wird gelöst durch eine elektromagnetische Verstelleinrichtung mit den Merkmalen des Patentanspruchs 1 sowie durch die Verwendung einer solchen elektromagnetischen Verstelleinrichtung mit den Merkmalen des Patentanspruchs 3.This object is achieved by an electromagnetic adjusting device having the features of patent claim 1 and by the use of such an electromagnetic adjusting device having the features of patent claim 3.

  • a second transistor element is provided with a control electrode which connects the second terminal of the magnetic coil to the third plug contact,

Damit kann mit dieser H-Schaltung und den dadurch geschaffenen drei Steckerkontakten ein Stecker bereitgestellt werden, der mit einem Stecker für eine Verstellvorrichtung mit zwei Magnetspulen kompatibel ist.This arrangement according to the invention with a single magnetic coil and the two transistor elements is an H-circuit, on the one hand two Bestromungsrichtungen the current through the single solenoid can be realized and on the other hand, as in an adjustment with two magnetic coils also three plug contacts are created.
