Abstract
In a mixing valve (6) for an internal combustion engine (1) of a motor vehicle, the distance between pivot axes (12, 13) of two flaps (10, 11) is smaller than the diameter of the largest flap (10). The flaps (10, 11) are also connected to a single drive device (8). The drive device (8) ensures a collision-free coupling of the movements of the flaps (10, 11). As a result, the design of said mixing valve (6) is particularly compact.
Description
Beschreibung description
Mischventil einer Brennkraftmaschine eines Kraftfahrzeuges Die Erfindung betrifft ein Mischventil einer Brennkraftmaschine eines Kraftfahrzeuges mit einer in einem Ansaugkanal angeordneten Klappe und einer in einem Abgasrückführungskanal angeordneten Klappe, wobei der Ansaugkanal und der Abgasrückführungskanal in einen gemeinsamen Sammelkanal münden, und mit einer Antriebseinrichtung zum Antrieb der Klappen. The invention relates to a mixing valve of an internal combustion engine of a motor vehicle having a flap arranged in an intake passage and a flap arranged in an exhaust gas recirculation passage, the intake passage and the exhaust gas recirculation passage opening into a common collection passage, and drive means for driving the flaps.
Solche Mischventile werden bei Abgasrückführungs Systemen von Brennkraftmaschinen heutiger Kraftfahrzeuge häufig eingesetzt und sind aus der Praxis bekannt. Die Bewegungen der Ansaug- klappe und der Abgasklappe sind derart gesteuert, dass dieSuch mixing valves are often used in exhaust gas recirculation systems of internal combustion engines of modern motor vehicles and are known from practice. The movements of the intake flap and the exhaust flap are controlled such that the
Abgasklappe ausgehend von der ersten Stellung linear mit einem Ansteuersignal der Antriebseinrichtung öffnet. Die Ansaugklappe verharrt jedoch zunächst in der ersten Stellung und wird erst oberhalb eines vorgesehenen AnsteuerSignals ge- schlössen. Exhaust flap opens starting from the first position linearly with a drive signal of the drive device. However, the intake flap initially remains in the first position and is closed only above a planned drive signal.
Die Klappen der bekannten Mischventile weisen einen Abstand auf, der zumindest dem Durchmesser der größeren der Klappen entspricht. Hierdurch wird eine Kollision der Klappen verhin- dert. Die unterschiedlichen Antriebe der Klappen erfordern einen großen Bauraum, welcher jedoch häufig nicht zur Verfügung steht. The flaps of the known mixing valves have a distance which corresponds at least to the diameter of the larger of the flaps. This prevents a collision of the flaps. The different drives of the flaps require a large amount of space, which, however, is often not available.
Der Erfindung liegt das Problem zugrunde, ein Mischventil der eingangs genannten Art so zu gestalten, dass es einen besonders kleinen Bauraum aufweist. The invention is based on the problem to design a mixing valve of the type mentioned so that it has a very small space.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Abstand von Schwenkachsen der Klappen kleiner ist als der Durchmesser der größten Klappe, und dass Schwenkbewegungen der Klappen kollisionsfrei gekoppelt sind.
Durch diese Gestaltung stellt die Koppelung der Schwenkbewegungen der Klappen sicher, dass die Klappen trotz Überschneidung ihrer Schwenkbewegungen nicht miteinander kollidieren. Daher lassen sich die Schwenkachsen der Klappen besonders na- he zusammen anordnen. Gleichzeitig sind hierdurch die Mittel zum Antrieb der Klappen ebenfalls nahe zusammen angeordnet. Damit weist das Mischventil einen besonders kleinen Bauraum auf . Die kollisionsfreie Führung der Klappen gestaltet sich gemäß einer vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Klappen gleichsinnig geführt sind. This problem is inventively solved in that the distance of pivot axes of the flaps is smaller than the diameter of the largest flap, and that pivotal movements of the flaps are coupled without collision. As a result of this configuration, the coupling of the pivoting movements of the flaps ensures that the flaps do not collide with one another despite the overlapping of their pivotal movements. Therefore, the pivot axes of the flaps can be arranged particularly close together. At the same time thereby the means for driving the flaps are also arranged close together. Thus, the mixing valve has a particularly small space. The collision-free guidance of the flaps is particularly simple according to an advantageous development of the invention, when the flaps are guided in the same direction.
Der bauliche Aufwand zum Antrieb der Klappen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn die Antriebseinrichtung einen einzigen Elektromotor hat und wenn der Elektromotor über jeweils ein Stellmittel mit den Klappen verbunden ist. Damit ermöglicht das Mischventil den vollständigen Ersatz zweier einzelner Ventile. Dank der Erfindung werden zahlreiche Bauteile, wie Gehäuse, Deckel, Sensorik und Steckanschluss für den Elektromotor nur einfach benötigt. Damit bietet das erfindungsgemäße Mischventil neben dem Bauraumvorteil auch einen großen Kostenvorteil. The structural complexity for driving the flaps can be kept particularly low according to another advantageous embodiment of the invention, when the drive device has a single electric motor and when the electric motor is connected via a respective adjusting means with the flaps. Thus, the mixing valve allows the complete replacement of two individual valves. Thanks to the invention, numerous components, such as housing, cover, sensors and plug connection for the electric motor are simply needed. Thus, the mixing valve according to the invention in addition to the space advantage also offers a major cost advantage.
Der Elektromotor kann gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen Elektromotor mit besonders kleinen Abmessungen aufweisen, wenn zumindest eines der Stellmittel ein Zahnradgetriebe mit mehreren Zahnrädern auf- weist. Solche Elektromotoren weisen meist eine hohe Drehzahl auf. Das Zahnradgetriebe ermöglicht die Übersetzung der hohen Drehzahl des Elektromotors auf die vorgesehene Schwenkbewegung der Klappen. Die Bewegungsabfolge der Klappen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach steu-
ern, wenn zwischen dem einen Stellmittel und der Klappe eine Kupplung angeordnet ist. The electric motor may according to another advantageous embodiment of the invention have an electric motor with particularly small dimensions, if at least one of the actuating means has a gear transmission with multiple gears up. Such electric motors usually have a high speed. The gear transmission allows the translation of the high speed of the electric motor to the intended pivotal movement of the flaps. The sequence of movements of the flaps can be easily controlled according to another advantageous development of the invention. ern when a coupling is arranged between the one adjusting means and the flap.
Die Kupplung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die Kupplung eine Klauenkupplung mit einem Totgang ist. The coupling is structurally particularly simple according to another advantageous embodiment of the invention, when the clutch is a dog clutch with a backlash.
Die Bewegungsabfolge und die Bewegungsgeschwindigkeit der Klappen lassen sich gemäß einer anderen vorteilhaften Weiter- bildung der Erfindung besonders vielseitig gestalten, wenn zumindest eines der Stellmittel eine Steuerkurve zur Führung eines Steuerteils aufweist. The sequence of movements and the speed of movement of the flaps can be made particularly versatile according to another advantageous development of the invention, if at least one of the actuating means has a control cam for guiding a control part.
Die Steuerkurve und das Steuerteil gestalten sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn die Steuerkurve auf der Außenkontur eines angetriebenen Rades angeordnet ist und wenn das Steuerteil eine mit einer der Klappen verbundene, auf der Steuerkurve abrollende Rolle ist. Vorzugsweise ist die Klappe mit Rad gegen die Außenkontur federelastisch vorgespannt. Insbesondere die Kombination des Antriebs der einen Klappe mittels der Steuerkurve und der anderen Klappe mittels des Zahnradgetriebes ermöglicht die besonders geringen Abmessungen des Mischventils . The cam and the control part designed according to another advantageous embodiment of the invention structurally particularly simple when the control cam is arranged on the outer contour of a driven wheel and when the control part is connected to one of the flaps, rolling on the control cam role. Preferably, the flap is resiliently biased with wheel against the outer contour. In particular, the combination of the drive of a flap by means of the control cam and the other flap by means of the gear transmission allows the particularly small dimensions of the mixing valve.
Die Anzahl von Lagerstellen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn das die Steuerkurve aufweisende Rad auf einem Zahnrad des Zahnradgetriebes angeordnet ist. Dies trägt zu einer weiteren Verringerung der Abmessungen des Mischventils bei . The number of bearings can be kept particularly low according to another advantageous embodiment of the invention, when the cam having the wheel is arranged on a gear of the gear transmission. This contributes to a further reduction in the size of the mixing valve.
Die in dem Ansaugkanal und dem Abgasrückführungskanal strömenden Gase lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung beliebig mischen, wenn in einerThe flowing in the intake passage and the exhaust gas recirculation passage gases can be mixed according to another advantageous embodiment of the invention as desired, if in one

Figur 1 zeigt schematisch eine Brennkraftmaschine 1 mit einer Ansaugleitung 2 und mit einer Abgasleitung 3. Die Ansaugleitung 2 hat einen Ansaugkanal 4, über den Luft aus der Umge- bung angesaugt wird. Von der Abgasleitung 3 führt ein Abgasrückführungskanal 5 über ein Mischventil 6 in die Ansaugleitung 2. Das Mischventil 6 führt den Ansaugkanal 4 und den Abgasrückführungskanal 5 zu einem Sammelkanal 7 zusammen. Der Sammelkanal 7 führt unmittelbar zu der Brennkraftmaschine 1. Eine Antriebseinrichtung 8 mit einem Elektromotor 9 ermöglicht eine Verstellung des Mischventils 6. FIG. 1 schematically shows an internal combustion engine 1 with an intake line 2 and with an exhaust gas line 3. The intake line 2 has an intake passage 4, via which air is drawn in from the environment. From the exhaust pipe 3, an exhaust gas recirculation passage 5 leads via a mixing valve 6 into the intake passage 2. The mixing valve 6 merges the intake passage 4 and the exhaust gas recirculation passage 5 to form a collecting passage 7. The collecting channel 7 leads directly to the internal combustion engine 1. A drive device 8 with an electric motor 9 enables an adjustment of the mixing valve 6.
Figur 2 zeigt das Mischventil 6 aus Figur 1 mit der Antriebseinrichtung 8. Zur Vereinfachung ist die Antriebseinrichtung 8 schematisch dargestellt. Das Mischventil 6 hat eine in dem Ansaugkanal 4 angeordnete schwenkbare Klappe 10 und eine in dem Abgasrückführungskanal 5 angeordnete schwenkbare Klappe 11. Die im Ansaugkanal 4 angeordnete Klappe 10 ist geringfügig größer als die im Abgasrückführungskanal 5 angeordnete Klappe 11. Der Abstand von Schwenkachsen 12, 13 der Klappen 10, 11 beträgt etwa 80 % des Durchmessers der größeren, im Ansaugkanal 4 angeordneten Klappe 10.
Die Klappen 10, 11 werden über den einzigen Elektromotor 9 angetrieben. Die Schwenkrichtung der Klappen 10, 11 verläuft gleichsinnig, wie es in der Zeichnung mit Pfeilen verdeutlicht ist. Hierfür hat die Antriebseinrichtung 8 erste, zu der einen im Ansaugkanal 4 angeordneten Klappe 10 führendeFIG. 2 shows the mixing valve 6 from FIG. 1 with the drive device 8. To simplify matters, the drive device 8 is shown schematically. The mixing valve 6 has a arranged in the intake passage 4 pivotable flap 10 and arranged in the exhaust gas recirculation passage 5 pivotal flap 11. The arranged in the intake passage 4 flap 10 is slightly larger than the arranged in the exhaust gas recirculation passage 5 flap 11. The distance from pivot axes 12, 13 the flaps 10, 11 is about 80% of the diameter of the larger, arranged in the intake passage 4 flap 10th The flaps 10, 11 are driven by the single electric motor 9. The pivoting direction of the flaps 10, 11 extends in the same direction, as illustrated in the drawing with arrows. For this purpose, the drive device 8 has first, leading to the arranged in the intake passage 4 flap 10
Stellmittel 14 und zweite, zu der im Abgasrückführungskanal 5 angeordneten Klappe 11 führende Stellmittel 15. Die zu der im Ansaugkanal 4 angeordneten Klappe 10 führenden Stellmittel 14 haben ein Zahnradgetriebe 16 mit mehreren Zahnrädern 17 und eine Kupplung 18. Die Kupplung 18 hat einen Totgang 19, um den die Zahnräder 17 angetrieben werden können, ohne dass die Klappe 10 mitbewegt wird. Adjusting means 14 and second, to the arranged in the exhaust gas recirculation passage 5 flap 11 leading actuating means 15. The arranged in the intake passage 4 flap 10 leading actuating means 14 have a gear transmission 16 with a plurality of gears 17 and a clutch 18. The clutch 18 has a backlash 19, by which the gears 17 can be driven without the flap 10 is moved.
Die zu der im Abgasrückführungskanal 5 angeordneten Klappe 11 führenden Stellmittel 15 weisen eine Steuerkurve 20 zur Bewegung eines Steuerteils 21 auf. Das Steuerteil 21 ist über einen Hebel 22 mit der im Abgasrückführungskanal 5 angeordneten Kappe 11 verbunden. Die Steuerkurve 20 ist auf der Außenkontur eines von dem Zahnradgetriebe 16 angetriebenen Rades 23 angeordnet. Das Steuerteil 21 ist als auf der Außenkontur abrollende Rolle ausgebildet. The arranged in the exhaust gas recirculation passage 5 flap 11 actuating means 15 have a control cam 20 for moving a control part 21. The control part 21 is connected via a lever 22 with the arranged in the exhaust gas recirculation passage 5 cap 11. The control cam 20 is arranged on the outer contour of a gear 23 driven by the gear wheel. The control part 21 is designed as a roll rolling on the outer contour.
Beide Klappen 10, 11 sind von nicht dargestellten Federelementen in die Offenstellung vorgespannt. Die Antriebseinrich- tung 8 treibt damit die Klappen 10, 11 in die Schließrichtung an . Both flaps 10, 11 are biased by spring elements, not shown, in the open position. The drive device 8 thus drives the flaps 10, 11 in the closing direction.
Figur 3 zeigt den Öffnungswinkel Ot der Klappen 10, 11 über einen Bewegungsbereich des Zahnradgetriebes 16. Die Bewegung der im Ansaugkanal 4 angeordneten Klappe 10 ist mit I und die Bewegung der im Abgasrückführungskanal 5 angeordneten Klappe 11 ist mit II gekennzeichnet. Zur Vereinfachung ist der Bewegungsbereich in Prozentwerten dargestellt. Hierbei ist zu erkennen, dass in einem Ausgangszustand von 0 % des Bewegungs- bereichs die Klappe 10 des Ansaugkanals 4 vollständig geöffnet ist, während die Klappe 11 des Abgasrückführungskanals 5 vollständig geschlossen ist. Bei einem Antrieb des Zahnradge-
triebes 16 auf 50 % des Bewegungsbereichs sind beide Klappen 10, 11 vollständig geöffnet. Anschließend schließt sich die im Ansaugkanal 4 angeordnete Klappe 10 vollständig, während die im Abgasrückführungskanal 6 angeordnete Klappe 11 in der vollständig geöffneten Stellung verbleibt.
FIG. 3 shows the opening angle Ot of the flaps 10, 11 over a range of movement of the toothed gear 16. The movement of the flap 10 arranged in the intake channel 4 is indicated by I and the movement of the flap 11 arranged in the exhaust gas recirculation channel 5 is indicated by II. For convenience, the range of motion is shown in percentage. It can be seen here that in an initial state of 0% of the movement range, the flap 10 of the intake duct 4 is completely open, while the flap 11 of the exhaust gas recirculation duct 5 is completely closed. In a drive of the gear wheel drive 16 to 50% of the range of movement, both flaps 10, 11 are fully open. Subsequently, the flap 10 arranged in the intake passage 4 closes completely, while the flap 11 arranged in the exhaust gas recirculation passage 6 remains in the fully open position.
