Description

Fliehkraftregler zur selbsttätigen Verstellung des Zündzeitpunktes bei elektrischen Zündvorrichtungen. Die Fliehkraftregler zur selbsttätigen Verstellung des Zündzeitpunktes bei elektrischen Zündeinrichtungen, deren Schwungmassen unter dem Einfluß einfacher Federn stehen, haben den Nachteil, daß die Verstellkurve nicht -die günstigste Form aufweist. Diese Regler geben bei den niedrigen und mittleren Drehzahlen des Motors zu wenig, bei Jen höheren Drehzahlen aber zu viel Verstellung.Centrifugal governor for automatic adjustment of the ignition point in electrical ignition devices. The centrifugal governor for automatic adjustment of the ignition point in electrical ignition devices whose centrifugal masses are below are under the influence of simple springs, have the disadvantage that the adjustment curve is not -has the most favorable shape. These controls give at the low and medium levels Speed of the motor too little, but too much adjustment at Jen higher speeds.

Es sind bereits Fliehkraftregler bekannt, bei denen zur Vermeidung dieses Nachteils die Verstellkurve der verlangten idealen Kurve dadurch einigermaßen angenähert wird, daß der Hauptfeder Hilfsfeiern parallel geschaltet sind, die nacheinander zur Wirkung kommen und auf diese Weise die Verstellung im Bereich .der höheren Drehzahlen immer mehr verlangsamen. Diese bekannten Einrichtungen weisen aber noch den Mangel auf, daß ,der Verstellwinkel für eine bestimmte Zunahme der Drehzahl' sich stufenweise ändert und id'ie Verstellkurve in den einzelnen Stufen die alte Gestalt behält.Centrifugal governors are already known in which to avoid this disadvantage the adjustment curve of the required ideal curve to some extent it is approximated that the main spring auxiliary celebrations are connected in parallel, one after the other come into effect and in this way the adjustment in the range of the higher speeds slow down more and more. However, these known devices still have the shortcoming on that 'the angle of adjustment for a certain increase in speed' is gradual changes and I keep the adjustment curve in the individual stages the old form.

Dieser Mangel wird nach der Erfindung dadurch behoben, daß die Abfederung der Schwungmasse des Reglers durch mindestens zwei ungleich starke hintereinandergeschaltete Federn erfolgt, die von Anfang an zugleich Beansprucht werden. Bei den niedrigen Drehzahlen wird zunächst die schwächere Feder genügen, um den Schwungmassen das Gleichgewicht zu halten. Je weiter sich diese Felder ihrer Endbeanspruchung nähert, bei der die Gänge aufeinanderliegen und mithin die Federung aufhört, desto mehr wird auch die stärkere Feder ihren Einfluß ausüben, bis diese allein zu wirken beginnt. Der Übergang geschieht demnach allmählich, wodurch eine stetig verlaufende Verstell:kurve erhalten wird.This deficiency is remedied according to the invention in that the cushioning the centrifugal mass of the controller by at least two unequal strengths connected in series Springs takes place, which are stressed from the beginning at the same time. At the low At first, the weaker spring will suffice to control the centrifugal masses Keep balance. The closer this field approaches its end use, in which the gears lie on top of each other and the suspension therefore stops, the more so the stronger pen will also exert its influence until this alone begins to work. The transition takes place gradually, creating a steady adjustment curve is obtained.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes durch Abb. i schematisch wiedergegeben. Die Abb. 2 bis q. zeigen verschiedene zur Verw@endung geeignete Federzusammenstellungen.The drawing shows an embodiment of the subject matter of the invention shown schematically by Fig. i. Fig. 2 to q. show different for Use of suitable spring combinations.

Der Regler besteht bei der dargestellten Ausführungsform in bekannter Weise aus zwei Scheiben, die Mitnehmer i bzw. 2 tragen. Zwischen jedem Mitnehmerpaar i und 2 sind kugel- oder walzenförmige Schwungmassen 3 angeordnet, die infolge der Fliehkraft nach außen streben und dabei die Mitnehmer i und 2 auseinanderdrücken, id. h. die zugehörigen Scheiben gegeneinander verdrehen. Zwischen je zwei benachbarte Mitnehmer i und 2 -ist eine Federung .4 eingeschaltet, die dazu dient, der Fliehkraft das Gleichgewicht zu halten.In the embodiment shown, the regulator is a known one Way of two disks that carry drivers i and 2 respectively. Between each pair of drivers i and 2 are spherical or cylindrical centrifugal masses 3 arranged, which as a result of Strive for centrifugal force to the outside while pushing drivers i and 2 apart, id. H. twist the corresponding disks against each other. Between every two neighboring ones Driver i and 2 -is a suspension .4 switched on, which serves to reduce the centrifugal force keep your balance.

Nach der Erfindung besteht die Federung 4 aus mindestens zwei ungleich starken, hintereinandergeschalteten Federn 5, 6, die von Anfang an gleichzeitig beansprucht werden. Bei der in Abb. i dargestellten Ausführung besteht die Federung .4 aus zwei miteinander verbundenen Einzelfedern 5, 6 ungleicher Stärke, wie sie beispielsweise in @bh.2 in größerem Maßstabe idargestellt sind. Die Verbindung der beiden Federn kann auf heliebige Weise erfolgen. Wie Abb. 2 ersehen läßt, kann man ein besonderes Zwischenstück 7 zwischen den Einzelfedern 5, 6 anbringen.According to the invention, the suspension 4 consists of at least two unequal strong, series-connected springs 5, 6, which from the beginning simultaneously are claimed. In the version shown in Fig. I, there is a suspension .4 from two interconnected individual springs 5, 6 of unequal strength as they for example in @ bh.2 are shown on a larger scale i. The connection of the both springs can be done in any way. As Fig. 2 shows, one can Attach a special intermediate piece 7 between the individual springs 5, 6.

An Stelle von Schraubenfedern kann man natürlich auch jede .andere Federart benutzen. Die Ausführung nach Abb. 3 zeigt eine Federzusammenstellung, die aus einer Schraubenfeder 5 und zwei Kegelfedern 6 an jedem Ende besteht. Bei der Ausführung nach Abb. .a. sind die Kegelfedern durch Klötze aus elastischem Material, z. B. Gummi, ersetzt.Instead of coil springs, you can of course use any other Use pen type. The design according to Fig. 3 shows a spring arrangement, which consists of a helical spring 5 and two conical springs 6 at each end. at the design according to Fig. a. the conical springs are made of elastic material, z. B. rubber replaced.

Die Zahl und die Bemessung der Federn ist beliebig und richtet sich nach der Form :der Verstellungskurve, die man erzielen will.The number and dimensioning of the springs is arbitrary and depends according to the shape: the adjustment curve that you want to achieve.
