Description

Die Erfindung bezieht sich auf ein Regelgestänge für Brennstoffeinspritzvorrichtungen für Dieselmotoren mit in wenigstens einer Reihe angeordneten Motorzylindern, von derjenigen Bauart, bei welcher Einspritzpumpe und Einspritzdüse zu einer je einem Motorzylinder zugeordneten Pumpendüse-Einheit vereinigt sind, welche eine in die Pumpendüse-Einheit integrierte axial verschiebbare Regelstange aufweist, wobei die integrierte Regelstange mit einer am Motor parallel zur Motorlängsachse gelagerten Regelwelle kuppelbar ist. Eine derartige Ausbildung ist aus der US-A-4 036 196 bekannt geworden wobei bei dieser Ausbildung nach Lösung der Kupplung der integrierten Regelstange mit der am Motor parallel zur Motorlängsachse gelagerten Regelwelle ein Ausbau der Pumpedüse-Einheit ohne Schwierigkeiten möglich war.The invention relates to a control linkage for fuel injection devices for diesel engines with engine cylinders arranged in at least one row, of the type in which the injection pump and the injection nozzle are combined to form a pump nozzle unit, each associated with a motor cylinder, which has an axially displaceable integrated in the pump nozzle unit Has control rod, wherein the integrated control rod can be coupled to a control shaft mounted on the engine parallel to the engine longitudinal axis. Such a design has become known from US-A-4 036 196. In this design, after removing the coupling of the integrated control rod with the control shaft mounted on the motor parallel to the longitudinal axis of the motor, expansion of the pump nozzle unit was possible without difficulty.

Die Erfindung zielt nun darauf ab, eine derartig einfache Ausbaubarkeit der Pumpendüse-Einheit auch dann zu gewährleisten, wenn Pumpendüse-Einheiten mit zwei integrierten Regelstangen für die Beeinflussung verschiedener Betriebsparameter verwendet werden und zielt weiters darauf ab, einen derartigen Ausbau zu ermöglich, ohne daß hiebei die Einstellung der Regelung verändert wird, so daß eine Neujustierung nicht erforderlich wird.The invention now aims to ensure such a simple expansion of the pump nozzle unit even when pump nozzle units with two integrated control rods are used to influence various operating parameters, and further aims to enable such an expansion without this the setting of the control is changed so that a readjustment is not necessary.

Zur Lösung dieser Aufgabe besteht die Erfindung darin, daß eine zweite in die Pumpendüse-Einheit integrierte, axial verschiebbare Regelstange zur Beeinflussung eines weiteren Betriebsparameters mit einer zweiten am Motor parallel zur Motorachse gelagerten Regelwelle kuppelbar und ungefähr senkrecht zur Motorlängsachse im Gehäuse der Pumpen-Einheit verschiebbar geführt ist und an ihr ebenfalls ein Hebelarm angeordnet ist, daß die Hebelarme in an den Regelstangen angeordnete Gleitstücke eingreifen und, in Achsrichtung der Pumpendüse-Einheit gesehen, seitlich gegeneinander versetzt sind, und daß in Achsrichtung der Pumpendüse-Einheit gesehen, zumindest das Gleitstück der näher der Düse gelegenen Regelstange zumindest die von der Düse entferntere Regelwelle bei eingeschobener Regelstange nicht überschneidet. Auf diese Weise wird es auch bei Ausstattung der Pumpendüse-Einheit mit zwei Regelstangen ermöglicht, eine Pumpendüse-Einheit nach Lösung der Verschraubung einfach herauszuheben, da kein Teil der Regelwelle dem Ausbau im Wege steht. Hiebei können die Kipphebel in an sich bekannter Weise seitlich verschoben werden. Wesentlich hiebei ist, daß die in die Pumpendüse-Einheit integrierten Regelstangen ungefähr senkrecht zur Regelwelle stehen und durch Hebelarme betätigt werden, da dadurch der nötige freie Raum geschaffen wird. Es ist somit ein zeitraubender Ausbau der am Motor gelagerten Rege/welle nicht erforderlich und es muß keine Verbindung des Regelgestänges mit dem Regler gelöst werden. Es wird somit der Vorteil erreicht, daß die Einstellung der einzelnen Pumpendüse-Einheiten nicht verändert wird, da die Stellung der Hauptregelstange gegenüber dem Motorzylinderkopf erhalten bleibt. Wenn eine neue Pumpendüse-Einheit. eingebaut werden soll, so kann die Einstellung dieser Pumpendüse-Einheit am Prüfstand erfolgen. Die in der Pumpendüse-Einheit integrierten Regelstangen dienen in üblicher Weise zur Einstellung mehrer Betriebsparameter, wie zum Beispiel der Einspritzmenge und des Einspritzbeginnes.To achieve this object, the invention consists in that a second axially displaceable control rod integrated in the pump nozzle unit for influencing a further operating parameter can be coupled to a second control shaft mounted on the motor parallel to the motor axis and displaceable approximately perpendicular to the longitudinal axis of the motor in the housing of the pump unit is guided and a lever arm is also arranged on it, that the lever arms engage in sliders arranged on the control rods and, seen in the axial direction of the pump nozzle unit, are laterally offset from one another, and that seen in the axial direction of the pump nozzle unit, at least the slider of the control rod located closer to the nozzle does not overlap at least the control shaft which is more distant from the nozzle when the control rod is inserted. In this way, even if the pump nozzle unit is equipped with two control rods, it is possible to simply lift out a pump nozzle unit after loosening the screw connection, since no part of the control shaft stands in the way of removal. The rocker arms can be moved laterally in a manner known per se. It is essential that the control rods integrated into the pump nozzle unit are approximately perpendicular to the control shaft and are actuated by lever arms, since this creates the necessary free space. Time-consuming removal of the control shaft mounted on the motor is therefore not necessary, and there is no need to disconnect the control linkage from the controller. The advantage is thus achieved that the setting of the individual pump nozzle units is not changed, since the position of the main control rod relative to the engine cylinder head is retained. When a new pump nozzle unit. this pump nozzle unit can be set on the test bench. The control rods integrated in the pump nozzle unit are used in the usual way to set several operating parameters, such as the injection quantity and the start of injection.

Gemäß der Erfindung weisen die Hebelarme zweckmäßig Bolzen auf, welche in Achsrichtung der Pumpedüse-Einheit gesehen; seitlich in senkrecht zu den Achsen der Regelstangen angeordnete Nuten, vorzugsweise Ringnuten, der Gleitstücke eingreifen. Auf diese Weise können die Bolzen der Hebelarme beim Ausheben einer Pumpendüse-Einheit einfach aus den Nuten heraustreten.According to the invention, the lever arms expediently have bolts which are seen in the axial direction of the pump nozzle unit; engage laterally in grooves, preferably ring grooves, arranged perpendicular to the axes of the control rods, of the sliding pieces. In this way, the bolts of the lever arms can easily come out of the grooves when lifting out a pump nozzle unit.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Gleitstücke mit den Regelstangen einstellbar verbunden. Auf diese Weise wird es ermöglicht, die Pumpeneinheiten in uneingebautem Zustand zu justieren, was beispielsweise auf einem Prüfstand erfolgen kann. Gemäß der Erfindung können die Hebelarme auf den Regelwellen festgeklemmt sein, so daß auch hier die Einstellung der Hebel an der Regelwelle mittels einer Lehre erfolgen kann. Diese Einstellung kann ein für allemal beibehalten werden und da die Gleitstücke der Regelstangen der Pumpeneinheiten außerhalb der Einbaulage eingestellt werden können, ist der Wiedereinbau einer reparierten Pumpedüse-Einheit oder der Einbei einer neuen Pumpedüse-Einheit ohne Justierung der Regelung möglich.According to a preferred embodiment of the invention, the sliders are adjustably connected to the control rods. In this way it is possible to adjust the pump units in the unassembled state, which can be done for example on a test bench. According to the invention, the lever arms can be clamped on the control shafts, so that here too the setting of the levers on the control shaft can be carried out by means of a gauge. This setting can be retained once and for all, and since the slide pieces of the control rods of the pump units can be adjusted outside the installation position, it is possible to reinstall a repaired pump nozzle unit or to insert a new pump nozzle unit without adjusting the control.

In der Zeichnung ist die Erfindung an Hand von Ausführungsbeispielen schematisch erläutert.

  • Figuren 2 und 3 zeigen zwei Ausführungsformen einer Regelstange mit Gleitstück im Axialschnitt durch die Regelstange,
  • Figur 4 zeigt eine abgewandelte Anordnung der Pumpendüse-Einheit im Querschnitt durch die Regelwellen,
  • Figur 5 zeigt eine Draufsicht auf eine Pumpeneinheit nach Fig. 4 oder nach Fig. 1.
In the drawing, the invention is explained schematically using exemplary embodiments.
  • 1 shows a cross section through the upper part of a motor with an inserted pump nozzle unit.
  • FIGS. 2 and 3 show two embodiments of a control rod with a slider in axial section through the control rod,
  • FIG. 4 shows a modified arrangement of the pump nozzle unit in cross section through the control shafts,
  • FIG. 5 shows a top view of a pump unit according to FIG. 4 or according to FIG. 1.

Bei der Anordnung nach Fig. 1 stellt 1 die Pumpendüse-Einheit dar, welche in den Zylinderkopf 2 eines Reihenmotors 3 eingesetzt ist. Der Antrieb der Pumpendüse-Einheit erfolgt von einer Nockenwelle 4 über einen Kipphebel 5. Der Kipphebel 5 ist in nicht dargestellter Weise auf der Kipphebelwelle 6 seitlich verschiebbar, so daß er beim Ausbau einer Pumpendüse-Einheit diese freigibt.In the arrangement according to FIG. 1, 1 represents the pump nozzle unit, which is inserted into the cylinder head 2 of an in-line engine 3. The pump nozzle unit is driven by a camshaft 4 via a rocker arm 5. The rocker arm 5 is laterally displaceable on the rocker arm shaft 6 in a manner not shown, so that when a pump nozzle unit is removed it releases it.

In die Pumpendüse-Einheit 1 sind zwei Regelstangen 7 und 8 integriert, das heißt, sie sind im Gehäuse der Pumpendüse-Einheit 1 geführt. Eine dieser Regelstangen, beispielsweise die Regelstange 7, regelt die Einspritzmenge, und die zweite, beispielsweise die Regelstange 8, regelt den Einspritzzeitpunkt.Two control rods 7 and 8 are integrated in the pump nozzle unit 1, that is to say they are guided in the housing of the pump nozzle unit 1. A this control rod, for example control rod 7, regulates the injection quantity, and the second, for example control rod 8, regulates the injection timing.

Der Regelstange 7 ist eine Regelwelle 9 zugeordnet, welche am Motor 3 drehbar gelagert ist und von einem Regler verdreht wird. Der Regelstange 8 ist eine Regelwelle 10 zugeordnet, welche gleichfalls am Motor verdrehbar gelagert ist und von einem Regler gesteuert ist. Beide Regelwellen 9 und 10 erstrecken sich über die Länge des Reihenmotors 3. Die Regelstangen 7 und 8 sind mit Gleitstücken 11 und 12 verbunden, welche senkrecht zur Achse dieser Regelstangen stehende Ringnuten 13 und 14 aufweisen, in welche Hebelarme 15 und 16, die auf den Regelwellen 9 und 10 mittels Klemmstücken 17 aufgeklemmt sind, mit Bolzen 18 eingreifen. Die Regelstangen und die Kipphebel sind, wie Fig. 5 zeigt, in Draufsicht seitlich gegeneinander versetzt und es sind daher auch die Hebel 15 und 16 seitlich gegeneinander versetzt. Wie Fig. 4 und 5 zeigen, überschneidet bei eingeschobenen Regelstangen 7 und 8 kein Teil der unteren Regelstange 8 die obere Regelwelle 9, so daß in dieser Lage die Pumpedüse-Einheit nach seitlicher Verschiebung der Kipphebel 5 und nach Lösung der in die Bohrungen 19 eingreifenden Befestigungsschrauben nach oben ausgehoben werden kann.The control rod 7 is assigned a control shaft 9 which is rotatably mounted on the motor 3 and is rotated by a controller. The control rod 8 is assigned a control shaft 10, which is also rotatably mounted on the engine and is controlled by a controller. Both control shafts 9 and 10 extend over the length of the in-line motor 3. The control rods 7 and 8 are connected to sliders 11 and 12, which have ring grooves 13 and 14 perpendicular to the axis of these control rods, into which lever arms 15 and 16, which on the Control shafts 9 and 10 are clamped by means of clamping pieces 17, engage with bolts 18. 5, the control rods and the rocker arms are laterally offset from one another in plan view, and therefore the levers 15 and 16 are also laterally offset from one another. 4 and 5 show, with inserted control rods 7 and 8, no part of the lower control rod 8 overlaps the upper control shaft 9, so that in this position the pump nozzle unit after lateral displacement of the rocker arm 5 and after loosening the engaging in the holes 19 Fastening screws can be lifted up.

Die Gleitstücke 11 und 12 sind mit den Regelstangen 7 bzw. 8 einstellbar verbunden. Zu diesem Zweck sind die Gleitstücke 11 und 12 mit Schraubenbolzen 20 einstückig ausgebildet, welche in axiale Gewindebohrungen 21 der Regelstangen 7 und 8 eingeschraubt sind. Auf diese Weise können die möglichen Toleranzen auf der Pumpendüse-Einheit selbst ausgeglichen werden und es können die entsprechenden Betriebsparameter richtig eingestellt werden. Dies kann bei dem Ausführungsbeispiel nach Fig. 2 durch eine oder mehrere Abstimmscheiben 22 erfolgen. Es kann somit bei einem bestimmten Betriebsparameter der Abstand a richtig präzise eingestellt werden.The sliders 11 and 12 are adjustably connected to the control rods 7 and 8, respectively. For this purpose, the sliders 11 and 12 are integrally formed with bolts 20 which are screwed into axial threaded bores 21 of the control rods 7 and 8. In this way, the possible tolerances on the pump nozzle unit itself can be compensated and the corresponding operating parameters can be set correctly. In the exemplary embodiment according to FIG. 2, this can be done by one or more tuning disks 22. The distance a can thus be set precisely with a certain operating parameter.

Die Ausführungsform nach Fig. 3 zeigt eine an sich bekannte Art der Schraubensicherung, welche darin besteht, daß in den Gewindebolzen ein Kunststoffpfropfen 23 eingesetzt ist. Es kann auch ein als Sicherung an sich bekannter Kunststoffring verwendet werden oder es kann die Schraubverbindung auch verklebt werden.The embodiment of Fig. 3 shows a known type of screw locking, which consists in that a plastic plug 23 is inserted into the threaded bolt. A plastic ring known as a fuse can also be used, or the screw connection can also be glued.

Die Ausführungsform nach Fig. 4 unterscheidet sich von der Ausführungsform nach Fig. 1 lediglich dadurch, daß die Regelstangen 7 und 8 axial näher beieinander liegen. Es ist hier strichpunktiert auch die Möglichkeit eingezeichnet, daß die Regelwellen 9 und 10 auf der, anderen Seite der Pumpendüse-Einheit 1 liegen.The embodiment of FIG. 4 differs from the embodiment of FIG. 1 only in that the control rods 7 and 8 are axially closer together. The dash-dotted line also shows the possibility that the control shafts 9 and 10 are on the other side of the pump nozzle unit 1.
