Abstract

The device consists of a first electric pulse generator whose output frequency is proportional to the nominal speed; a second pulse generator whose output frequency is proportional to the actual speed. Further elements serving as regulator and control element. The functions of the regulator and the control element are carried out in common by a device consisting of two electric stepping motors driving a differential gear in opposite directions. A pulse train corresponding to the nominal speed supplies one motor, and a pulse train corresponding to the actual speed the other motor.

Description

Einrichtung zur GeschwindigReitsrefelung eines mechanischDevice for speed control of a mechanical

steuerbaren Rotors Die vorliegende erfindung betrifft eine Einrichtung zur Geschwindigkeitsregelung eines mechanisch steuerbaren rotors, bestehend aus einem ersten elektrischen Impulsgeber, dessen Ausgangs frequenz zua Sollwert proportional ist, einem zweiten elektrischen Impulsgeber, dessen Ausgangsfrequenz zum Istwert proportional ist, sowie aus Elementen, die als Regler und Stellglied dienen.controllable rotor The present invention relates to a device for speed control of a mechanically controllable rotor, consisting of a first electrical pulse generator, the output frequency of which is proportional to the setpoint value is, a second electrical pulse generator, the output frequency of which corresponds to the actual value is proportional, as well as from elements that serve as regulators and actuators.

Solche Einrichtungen sind insbesondere für Kraftfahrzeuge mit Verbrennungsmotoren bekannt geworden. Dabei werden als Regler elektronische Geräte und als Stellglieder elektro-pneumatische, elektro-hydraulische o.a. Anordnungen eingesetzt, was zu erheblichen Nachteilen führt.Such devices are in particular for motor vehicles with internal combustion engines known. Electronic devices are used as regulators and actuators electro-pneumatic, electro-hydraulic or similar arrangements are used, which leads to considerable Disadvantages leads.

Elektronische Regler müssen sehr aufwendig gestaltet sein, damit Kurzschlüsse oder Polvertauschungen, die z. B. durch Unachtsamkeit oder durch mangelnde Spezialkenntnisse bei der Kfz.-Wartung entstehen, keine Zerstörungen bewirken. Elektro-pneumatische oder elektro-hydraulische Stellglieder machen elektronische Regler erforderlich und bringen es zusätzlich mit sich, daß das gesamte Regelsystem unerwünschte Schwingungen ausführt. Hydraulische Elemente erfordern darüber hinaus eine zusätzliche hydraulische Druckquelle.Electronic regulators have to be designed in a very complex way to prevent short circuits or pole reversals, e.g. B. through carelessness or a lack of specialist knowledge arise during vehicle maintenance, do not cause any damage. Electro-pneumatic or electro-hydraulic actuators require electronic regulators and also bring with it that the entire control system unwanted vibrations executes. Hydraulic elements also require an additional hydraulic system Pressure source.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache Linrichtung zur Geschwindigkeitsregelung zu schaffen, die weder pneumatische noch hydraulische Elemente enthalt und sich außerdem durch geringe @töranfälligkeit und gute Regeleigenschaften auzzeichnet.The invention is based on the object of a simple Linrichtung to create speed control that is neither pneumatic nor hydraulic Contains elements and is also characterized by low susceptibility to failure and good control properties excellent.

Dies wird erfindungsgemäß dadurch erreicht, daß die Funktionen dns Reglers und des otellgliedes gemeinsam von einer elestromechanischen Baugruppe übernommen werden. Diese eletro-mechanische Baugruppe besteht aus einem Differentialgetriebe und zwei elektrischen Uchrittmotoren, die gegenläufig auf das i)ifferentialgetriebe wirken.This is achieved according to the invention in that the functions dns Controller and the otellgliedes taken over jointly by an electromechanical assembly will. This electro-mechanical assembly consists of a differential gear and two electric stepper motors, which run in opposite directions on the i) ifferential gear works.

Die Zeichnung zeigt ein Ausführungsbeispiel der Geschwindigkeitsregeleinrichtung. Anhand der Zeichnung sei das Prinzip erläutert.The drawing shows an embodiment of the speed control device. The principle is explained using the drawing.

Der erste chrittmotor 2 wird von den Impulsen des ersten Impulsgebers 1 gespeist, dessen Ausgangsfrequenz proportional zur Soll-Geschwindig.eit ist. Der zweite Schrittmotor 3 wird von den Impulsen des zweiten Impulsgebers 4 gespeist, dessen Ausgangsfrequenz zur Ist-Geschwindigkeit proportional ist. Da die beiden Schrittnotoren gegenläufig auf das Differentialgetriebe 5 wirken, dreht sich die Ausgangswelle 6 des Getriebes mit einer Winkelgeschwindigkeit, die proportional zur Differenz aus Sollwert und Istwert ist. Die mechanische Steuervorrichtung des rotors - also z.B. das Gasgestänge 7 - wird durch die Ausgangswelle des Getriebes verstellt, wobei Verstell-ltichQung und -Geschwindigkeit der Regel abweichung entsprechen. Die Schrittweite der Schrittmotoren und das Ubersetzungsverhältnis des Differentialgetriebes werden so gewählt, daß einerseits kein Oberschwingen durch zu hohe Stell-Geschwindigkeit auftritt und andererseits die Reaktionszeit nicht zu groß wird.The first stepper motor 2 is controlled by the pulses from the first pulse generator 1, the output frequency of which is proportional to the target speed. Of the second stepping motor 3 is fed by the pulses of the second pulse generator 4, whose output frequency is proportional to the actual speed. There the two Stepper motors act in opposite directions on the differential gear 5, the rotates Output shaft 6 of the gearbox at an angular speed that is proportional to the difference between the setpoint and the actual value. The mechanical control device of the rotors - e.g. the throttle linkage 7 - is driven by the output shaft of the gearbox adjusted, whereby the adjustment speed and speed correspond to the control deviation. The step size of the stepper motors and the transmission ratio of the differential gear are chosen so that on the one hand there is no harmonic oscillation due to an excessively high setting speed occurs and on the other hand the response time is not too long.

Als Impulsgeber für die der Ist-Geschwindigkeit entsprechende Impulsfolge kann z.B. ein geeignetes elektronisches Tachometer verwendet werden. Da ein solches bei Kraftfahrzeugen z.B. nicht durchweg zur Standard-Ausrüstung gehört, wird teilweise auch ein spezielles, z.I3. mit der Tachometerwelle verbundenes, Gerät verwendet. Die Erfindung sieht nun vor, auf ein solches zusätzliches Gerät zur Impulserzeugung zu verzichten und die benötigten Impulse an) Unterbrecherkontakt oder einem anderen geeigneten Punkt der Zündanlage abzugreifen, was besonders bei stationären rotoren von Vorteil ist, die nicht niit einem Tachometer ausgestattet sind.As a pulse generator for the pulse train corresponding to the actual speed For example, a suitable electronic tachometer can be used. Since such a not always part of the standard equipment in motor vehicles, for example, is partially also a special one, e.g. I3. device connected to the speedometer shaft is used. The invention now provides for such an additional device for generating pulses to do without and the required pulses to) breaker contact or another appropriate point of the ignition system to tap, which is especially true for stationary rotors which are not equipped with a tachometer is an advantage.

Die bekannten Einrichtungen besitzen zum Teil Analog- oder Digital-Speicher, in die zu einem beliebigen Zeitpunkt der momentane Istwert übernommen werden kann, um als Sollwert zu dienen; dadurch erübrigt sich das manuelle Anstellen des Sollwertes.Some of the known devices have analog or digital memories, in which the current actual value can be adopted at any point in time, to serve as a set point; this eliminates the need to manually adjust the setpoint.

Die vorliegende Erfindung sieht dementsprechend vor, daß als Sollwert-Geber ein Impulsgeber verwendet wird, dessen Ausgangs frequenz in an sich bekannter eise durch die vorübergehend an einen entsprechenden Eingang angelegte Istwert-Impulsfolge bestimmt wird und danach für beliebig lange Zeit unverändert bleibt.The present invention accordingly provides that as a setpoint generator a pulse generator is used, the output frequency of which is known per se by the actual value pulse train temporarily applied to a corresponding input is determined and then remains unchanged for any length of time.
