Abstract
Description
einer Brennstoffeinspritzpumpe in Abhängigkeit von der Drehzahl sind an sich bekannt. Bei Einrichtungen dieser Art ist einer bestimmten Drehzahl eine bestimmte Einstellung des Förderbeginnes der Brennstoffpumpe zugeordnet. Es besteht nun aber in manchen Fällen, beispielsweise wenn die Forderung gestellt wird, daß der Motor mit Brennstoffen, welche verschiedene Verbrennungseigenschaften aufweisen, betrieben werden soll, das Bedürfnis, den Förderbeginn der Einspritzpumpe zusätzlich zur Abhängigkeit von der Drehzahl in Abhängigkeit von anderen Kenngrößen zu variieren. Dies erfordert bei den bekannten automatischen Spritzverstellern ein zusätzliches Aggregat. Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden.a fuel injection pump as a function of the speed are known per se. With facilities of this type, a certain speed is a certain setting of the start of delivery of the fuel pump assigned. However, in some cases, for example when the demand is made, that the engine can be operated with fuels which have different combustion properties should, the need to determine the start of delivery of the injection pump in addition to the dependence on the speed in To vary depending on other parameters. This requires the known automatic Injection adjusters an additional unit. The invention is based on this disadvantage to avoid.
Die Erfindung bezieht sich auf eine solche Einrichtung zur Verstellung des Förderbeginnes einer Brennstoffeinspritzpumpe für Brennkraftmaschinen, bei welcher die die Einspritzpumpe betätigende Welle mit einerThe invention relates to such a device for adjusting the start of delivery of a fuel injection pump for internal combustion engines, in which the injection pump actuating shaft with a
Antriebswelle über eine Muffe verbunden ist, die über 60 Verzahnung 4 besteht.The drive shaft is connected via a sleeve which consists of 60 teeth 4.
verzahnungen 6 und 7 in die beiden Verzahnungen 3 und 4 eingreift. Beim axialen Verschieben der Muffe 5 werden die Wellen 1 und 2 relativ zueinander verdreht, wodurch der Förderbeginn der Einspritzpumpe verändert wird.gears 6 and 7 engages in the two gears 3 and 4. When moving the sleeve axially 5 the shafts 1 and 2 are rotated relative to each other, whereby the start of delivery of the injection pump changes will.
Die Muffe 5 ist durch eine Feder 8 belastet und als Reglermuffe eines Fliehgewichtsreglers ausgebildet, dessen Gewichte mit 9 und dessen Fliehgewichtsträger mit 10 bezeichnet sind.The sleeve 5 is loaded by a spring 8 and designed as a regulator sleeve of a flyweight regulator, the weights of which are denoted by 9 and the centrifugal weight carrier by 10.
Der Fliehgewichtsträger 10 ist nun im Gegensatz zu einer bekannten Anordnung nicht fest, sondern axial verschiebbar auf cer Welle 1 angeordnet. Mit dem Fliehgewichtsträger 10 ist eine Brücke U fest verbunden, welche das Fliehgewichtsmeßwerk übergreift. Diese Brücke weist einen ringförmigen Hals 12 auf, welcher mit einer Innenverzahnung 13 ausgebildet ist, durch welche über die Brücke 11 der Fliehgewichtsträger 10 mit der Welle 2 drehsicher gekuppelt ist, wobei jedoch eine axiale Verschiebemöglichkeit in derIn contrast to a known arrangement, the flyweight carrier 10 is not fixed, but rather axial Slidably arranged on cer shaft 1. A bridge U is fixed to the flyweight carrier 10 connected, which overlaps the flyweight measuring mechanism. This bridge has an annular neck 12 on, which is formed with an internal toothing 13, through which over the bridge 11 of the flyweight carrier 10 is rotatably coupled to the shaft 2, but there is an axial displacement option in the
Verzahnungen mit verschiedenen Steigungen mit den beiden Wellen gekuppelt ist und die von einem drehzahlabhängigen Regelorgan aus einer Ausgangsstellung axial verschoben wird.Toothing with different pitches is coupled to the two shafts and that of one speed-dependent control element is axially displaced from a starting position.
Hierbei besteht die Erfindung darin, daß die Ausgangsstellung der Muffe willkürlich axial verstellbar ist.Here, the invention consists in that the starting position of the sleeve is axially adjustable at will is.
Dadurch, daß die Ausgangsstellung der Muffe Das Fliehgewichtsmeßwerk ist innerhalb eines Gehäuses 14 gelagert, welches beispielsweise mit dem Flansch 15 an die Einspritzpumpe angeflanscht sein kann. In diesem Gehäuse ist ein Schwenkhebel 16 mittels der Welle 17 schwenkbar gelagert. Dieser Schwenkhebel 16 greift mit einem Zapfen 18 an einem Gleitring 19 an, der in einer Ringnut 2C des ringförmigen Halses 12 der Brücke 11 gelagert ist. Durch Verschwen-In that the starting position of the sleeve The flyweight measuring mechanism is mounted within a housing 14, which, for example, with the Flange 15 can be flanged to the injection pump. A pivot lever 16 is located in this housing mounted pivotably by means of the shaft 17. This Swivel lever 16 engages with a pin 18 on a sliding ring 19, which is in an annular groove 2C of the annular Neck 12 of the bridge 11 is mounted. By wasting
ken des Schwenkhebels 16 über einen Handhebel 21 kann somit der Fliehgewichtsträger willkürlich axial verschoben werden, wodurch die Ausgangsstellung der Muffe 5 willkürlich verändert wird. Auf diese Weise wird die Grundeinstellung der Muffe 5, welche automatisch in Abhängigkeit von der Fliehkraft axial verschoben wird, und welche damit den Förderbeginn automatisch verändert, willkürlich verstellt so daß derken of the pivot lever 16 via a hand lever 21 can thus the flyweight carrier arbitrarily axially are moved, whereby the initial position of the sleeve 5 is changed arbitrarily. In this way is the basic setting of the sleeve 5, which is automatically axially dependent on the centrifugal force is shifted, and which thus automatically changes the start of delivery, arbitrarily adjusted so that the
Regelbereich des Förderbeginns willkürlich verschoben werden kann.The control range of the start of funding can be arbitrarily shifted.
In der Zeichnung sind Verzahnungen 3 und 4 dargestellt, von welchen eine schräg und eine gerade ist. Es können naturgemäß auch Schrägverzahnungen mit verschiedenen Steigungen verwendet werden, und es kann die Verzahnung auf einzelne Zähne bzw. Klauen reduziert werden.In the drawing, gears 3 and 4 are shown, one of which is oblique and one is straight. Of course, helical gears with different pitches can also be used, and it the toothing can be reduced to individual teeth or claws.
