Description

Antriebsanordnung mit einer Brennkraftmaschine, die ein einen Drive arrangement with an internal combustion engine that has a

Ungleichförmigkeitsgrad aufweisendes Drehmoment abgibt Die Erfindung betrifft eine Antriebsanordnung gemäß dem Oberbegriff des Patentanspruchs 1. Insbesondere bezieht sich die Erfindung auf eine Antriebsanordnung mit einer Anlaßlichtmaschine, wie sie aus der DE-OS 29 25 675 bekannt ist. Dort dient die Anlaßlichtmaschine, die zwischen zwei Kupplungen und damit sowohl vom nachgeschalteten Getriebe als auch von der vorgeschalteten Brennkraftmaschine trennbar liegt, also sowohl als Generator zur Erzeugung elektrischer Energie, d.h. zur Aufladung der Fahrzeugbatterie, als auch als Anlasser für die Brennkraftmaschine. Von besonderem Vorteil bei einer derartigen Konstruktion ist die Ausnutzung der Masse des Läufers der Anlaßlichtmaschine als Bestandteil der Masse des Schwungrads, das in bekannter Weise die Aufgabe hat, den Ungleichförmigkeitsgrad des von der Brennkraftmaschine abgegebenen Drehmoments zu verringern. Besonders betriebssicher durch Vermeidung von Stromzuführungen zum Läufer ist die bekannte Konstruktion deshalb, weil die Wicklungen der Anlaßlichtmaschine, also sowohl die gleichstromgespeiste Erregerwicklung als auch die Generator- und Motorwicklung, im Ständer untergebracht sind, also der Läufer wicklungsfrei ist. Torque exhibiting non-uniformity outputs The invention relates to a drive arrangement according to the preamble of claim 1. In particular the invention relates to a drive arrangement with a starting alternator, as known from DE-OS 29 25 675. The starter generator is used there, between two clutches and thus both from the downstream gearbox as is also separable from the upstream internal combustion engine, so both as Generator for generating electrical energy, i.e. for charging the vehicle battery, as well as a starter for the internal combustion engine. Of particular advantage with one Such a construction is the utilization of the mass of the rotor of the starting alternator as part of the mass of the flywheel, which in a known way has the task of the degree of irregularity in the torque output by the internal combustion engine to reduce. Particularly reliable by avoiding power supply to the The rotor is the well-known construction because the windings of the starting alternator, so both the DC-fed field winding and the generator and Motor winding, are housed in the stator, so the rotor is winding-free.

Zur Verringerung des Ungleichförmigkeitsgrads, der außer auf die Zündfolge der Maschine auf unterschiedliche, im einzelnen schwer zu beseitigende Störgrößen, wie schwankende Gemischzusammensetzung der Brennkraftmaschine, Schwankungen der Drehzahl und des Spitzendrucks in den Brennräumen, zurückzuführen ist, verwendet man in der Regel mechanische Einrichtungen, beispielsweise, wie bereits erwähnt, Schwungscheiben oder andere mechanische Hilfsmittel, die nach dem Trägheitsprinzip arbeiten. Insbesondere bei kleiner Brennraumzahl der Brennkraftmaschine ist eine ausreichende Verringerung des Ungleichförmigkeitsgrads aber nur mit erheblichem Mehraufwand erzielbar.To reduce the degree of irregularity other than the firing order the machine to different, individually difficult to eliminate disturbance variables, such as fluctuating mixture composition of the internal combustion engine, Fluctuations the speed and the peak pressure in the combustion chambers, is used one usually mechanical devices, for example, as already mentioned, Flywheels or other mechanical aids that work on the principle of inertia work. In particular if the internal combustion engine has a small number of combustion chambers, a sufficient reduction in the degree of nonuniformity but only with a considerable amount Additional effort achievable.

An dieser Stelle sei eingefügt, daß man unter dem Ungleichförmigkeitsgrad das Verhältnis aus größter auftretender Winkelgeschwindigkeitsdifferenz und mittlerer Winkelgeschwindigkeit versteht.At this point it should be added that under the degree of non-uniformity the ratio of the greatest occurring angular velocity difference and the mean Understand angular velocity.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebsanordnung gemäß dem Oberbegriff des Anspruchs 1 zu schaffen, bei der mit praktisch vernachlässigbarem zusätzlichen mechanischen Aufwand eine wirksame Verringerung des Ungleichförmigkeitsgrads erzielt wird.The invention is based on the object of providing a drive arrangement according to to create the preamble of claim 1, in which with practically negligible additional mechanical effort an effective reduction in the degree of non-uniformity is achieved.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Patentanspruchs 1.The inventive solution to this problem consists in the characterizing Features of claim 1.

Ein wesentlicher Vorteil der Erfindung ist also darin zu sehen, daß eine ohnehin vorhandene Einrichtung, nämlich die Lichtmaschine bzw. die Anlaß~ lichtmaschine, nicht nur zur Gewinnung der Schwungradmasse, sondern auch zur Bekämpfung des Ungleichsförmigkeitsgrads auf elektromagnetischem Wege, nämlich letztlich durch Erzielung eines kurbelwinkelabhängigen Gegendrehmoments, ausgenutzt wird, das auf die Ausgangswelle (Kurbelwelle) der Brennkraftmaschine übertragen wird. Dabei wird die an sich bekannte Tatsache ausgenutzt, daß das die Brennkraftmaschine belastende Lichtmaschinenmoment eine Funktion der abgegebenen elektrischen Lichtmaschinenleistung ist, die sich ihrerseits beispielsweise über den Erregerstrom der Lichtmaschine oder bei permanentmagnetischer Erregung über Halbleiterschalter steuern läßt.A major advantage of the invention is therefore to be seen in the fact that an already existing device, namely the alternator or the starting alternator, not only to obtain the flywheel mass, but also to combat the degree of irregularity in an electromagnetic way, namely ultimately by achieving a crank angle-dependent Counter torque, which is used on the output shaft (crankshaft) of the internal combustion engine is transmitted. The fact that is known per se is exploited that the The alternator torque that loads the internal combustion engine is a function of the output electrical alternator power is, in turn, for example about the excitation current of the alternator or in the case of permanent magnetic excitation Can control semiconductor switch.

Vorteilhafte Aus- und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Dabei ist die Aus rührung nach Patentanspruch 3 dann besonders sinnvoll, wenn beispielsweise infolge Vorhandenseins einer Kupplung zwischen Brennkraftmaschine und Läufer der Lichtmaschine keine winkeltreue Zuordnung der Stellungen von Ausgangswelle (Kurbelwelle) der Brennkraftmaschine und Läuferwelle gegeben ist. In jedem Falle muß aber zur Übertragung der mittels der Lichtmaschine erzeugten Gegendrehmomente in die Ausgangswelle der Brennkraftmaschine eine drehmomentübertragende, schlupffreie Verbindung (über Kupplung oder Zahnriemen) zwischen diesen beiden Einrichtungen vorhanden sein.Advantageous designs and developments of the invention are the subject matter of the subclaims. In this case, from the embodiment according to claim 3 is then particularly sensible, if, for example, due to the presence of a clutch between the internal combustion engine and rotor of the alternator no correct-angle assignment of the positions of the output shaft (Crankshaft) of the internal combustion engine and rotor shaft is given. In any case but must be used to transmit the counter torques generated by the alternator into the output shaft of the internal combustion engine a torque-transmitting, slip-free Connection (via coupling or toothed belt) between these two devices to be available.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert. Es zeigen: Fig. 1 schematisch eine Antriebsanordnung mit Anlaßlichtmaschine nach dem Prinzip und mit den Eigenschaften der Antriebsanordnung nach der eingangs genannten DE-OS 29 25 675 und Fig. 2 die erfindungsgemäßen Maßnahmen zur Verringerung des Ungleichförmigkeitsgrads.An embodiment of the invention is described below with reference to the Drawing explained. They show: FIG. 1 schematically a drive arrangement with a starting alternator according to the principle and with the properties of the drive arrangement according to the introduction mentioned DE-OS 29 25 675 and FIG. 2 the measures according to the invention for reducing the degree of non-uniformity.

Der Brennkraftmaschine 1 zum Antrieb der angetriebenen Räder 2 des hier angenommenen Kraftfahrzeugs ist über die Kupplung 3 der einen Bestandteil der Schwungscheibe 4 bildende wicklungsfreie Läufer 5 der ferner den Stator 6 aufweisenden Anlaßlichtmaschine 7 in Richtung des Energieflusses nachgeschaltet. Die Schwungscheibe 4 ist über die weitere Kupplung 8 mit dem Getriebe 9 verbindbar, das über das Differential 10 die angetriebenen Räder 2 antreibt.The internal combustion engine 1 for driving the driven wheels 2 of the The motor vehicle assumed here is one component of the clutch 3 via the clutch 3 Winding-free rotors 5 which form the flywheel 4 and which also have the stator 6 Starting dynamo 7 connected downstream in the direction of the energy flow. The flywheel 4 can be connected to the transmission 9 via the further clutch 8, which via the differential 10 drives the driven wheels 2.

Alle Wicklungen der Anlaßlichtmaschine 7 sind demgemäß im Ständer 6 derselben angeordnet; in Fig. 1 dargestellt sind nur die Wicklungsköpfe 11 und 12. Der Erregerstrom ist mit I1, der Generatorstrom mit I2 bezeichnet; er dient zum Aufladen der Batterie 13. Bei Umkehr der Stromrichtung (unterbrochen gezeichneter Pfeil in Fig. 1) handelt es sich um einen Motorstrom, der also bei Anlasserbetrieb vorliegt.All windings of the starting generator 7 are accordingly in the stator 6 of the same arranged; in Fig. 1 are shown only the winding heads 11 and 12. The excitation current is denoted by I1, the generator current by I2; he serves to charge the battery 13. If the current direction is reversed (interrupted drawn Arrow in Fig. 1) is a motor current, that is, when the starter is running is present.

Das Schwungrad 4 weist ferner den Zahnkranz 14 auf, dessen einzelne Zähne in konstanten Abständen aufeinanderfolgen, so daß in üblicher Weise mittels des elektromagnetischen Sensors 15 Signale für die jeweilige Drehzahl n, die der Winkelgeschwindigkeit proportional ist, der Schwungscheibe 4 und damit (bei geschlossener Kupplung 3) auch der Kurbelwelle 16 der Brennkraftmaschine gewonnen werden. Die Brennkraftmaschine 1 gibt ihrerseits das Drehmoment M ab. Bei der weiteren Betrachtung ist angenommen, daß die Kupplung 8 geöffnet ist.The flywheel 4 also has the ring gear 14, the individual Teeth follow one another at constant intervals, so that in the usual way by means of of the electromagnetic sensor 15 signals for the respective speed n, which the Angular velocity is proportional to the flywheel 4 and thus (with closed Clutch 3) can also be obtained from the crankshaft 16 of the internal combustion engine. the Internal combustion engine 1 in turn emits torque M. On further consideration it is assumed that the clutch 8 is open.

Wie bereits eingangs definiert, äußert sich der Ungleichförmigkeitsgrad durch Schwankungen der Winkelgeschwindigkeit der Kurbelwelle 16 und des Läufers 5 in Abhängigkeit von dem jeweiligen Kurbelwinkel. Diesen Schwankungen wird mit dem in Fig. 2 dargestellten Regelkreis entgegengewirkt. Regelstrecke ist die Brennkraftmaschine 1, der durch die Pfeile 20 und 21 angedeutete Störgrößen, wie unterschiedliche Gemischzusammensetzung, unterschiedliche Spitzendrücke in den Brennräumen, aufgeschaltet sind. Der mittels des Sensors 15 (Fig. 1) erfaßte Momentanwert für Drehzahl n bzw.As already defined at the beginning, the degree of non-uniformity is expressed by fluctuations in the angular velocity of the crankshaft 16 and the rotor 5 depending on the respective crank angle. These fluctuations are with counteracted the control loop shown in FIG. The controlled system is the internal combustion engine 1, the disturbance variables indicated by the arrows 20 and 21, such as different mixture compositions, different peak pressures in the combustion chambers. The means of of the sensor 15 (Fig. 1) detected instantaneous value for speed n or

Winkelgeschwindigkeit wird dem Differenzierglied 22 zur Gewinnung einer der Winkelbeschleunigung entsprechenden Größe zugeführt, die im Komparator 23 mit einem Sollwert 24 verglichen wird; die die Regelabweichung darstellende Ausgangsgröße des Komparators 23 gelangt in den Regler 25, der über den Verstärker 26 Erregerströme I1 und 11 an die das Stellglied des Regelkreises darstellende Anlaßlichtmaschine 7 liefert. Damit stellt sich ein bestimmter Generatorstrom I2, i2 und damit eine bestimmte, durch die Momente M und M gegebene kurbelwinkelabhängige Belastung der Brennkraftmaschine 1 durch die Anlaßlichtmaschine 7 ein, die im Sinne einer Ausregelung des Ungleichförmigkeitsgrads wirkt.Angular velocity is used by the differentiating element 22 to obtain a variable corresponding to the angular acceleration is fed to the comparator 23 is compared with a target value 24; the output variable representing the control deviation of the comparator 23 reaches the controller 25, which via the amplifier 26 generates excitation currents I1 and 11 to the starting generator which is the actuator of the control circuit 7 supplies. This results in a certain generator current I2, i2 and thus a certain, given by the moments M and M, the crank angle dependent load of the Internal combustion engine 1 through the starting alternator 7, which in the sense of a compensation of the degree of irregularity acts.

Es versteht sich von selbst, daß das Zeitverhalten des Stellglieds 7 demjenigen der Regelstrecke 1 angepaßt sein muß. Im übrigen ist der Aufwand für die erfindungsgemäßen Maßnahmen insbesondere dann sehr gering, wenn für den Regelkreis einschließlich Regelgrößenerfassung und Sollwertvorgabe ein üblicher Mikroprozessor Einsatz findet. Die Lichtmaschine bzw.It goes without saying that the time behavior of the actuator 7 must be adapted to that of the controlled system 1. Otherwise, the effort is for the measures according to the invention are very low in particular, if a common one for the control loop including control variable acquisition and setpoint specification Microprocessor is used. The alternator or

die Anlaßlichtmaschine kann nach unterschiedlichen Prinzipien arbeiten.the starting alternator can work according to different principles.

Beispielsweise kann eine Klauenpolmaschine, eine Reluktanzmaschine oder eine Asynchronmaschine Einsatz finden. Verwendet man eine permanent-erregte Synchronmaschine, so kann der Generatorstrom über Halbleiterschalter gesteuert bzw. geregelt werden. In allen Fällen bietet die Erfindung gegenüber rein mechanischen, nach dem Trägheitsprinzip arbeitenden Mitteln zur Verringerung des Ungleichförmigkeitsgrads den weiteren Vorteil der selbsttätigen Anpassung an den jeweils vorliegenden Ungleichförmigkeitsgrad.For example, a claw pole machine, a reluctance machine or an asynchronous machine can be used. If you use a permanently excited Synchronous machine, the generator current can be controlled or be managed. In all cases, the invention offers compared to purely mechanical, means operating on the principle of inertia to reduce the degree of non-uniformity the further advantage of the automatic adaptation to the respective degree of non-uniformity.
