Description
Die Erfindung betrifft ein Motorpumpenaggregat gemäß Oberbegriff von Anspruch 1.The The invention relates to a motor pump unit according to the preamble of claim 1.
Der Pumpenantrieb in Motorpumpenaggregaten für elektronische Kraftfahrzeugbremssysteme ist üblicherweise mit einem Gleichstrommotor ausgestattet, welcher einen Kommutator umfasst, der entsprechend der Stellung des Rotors in geeigneter Weise die Ankerwindungen des Rotors so ansteuert, dass der Motor eine Drehbewegung ausführt.Of the Pump drive in motor pump units for electronic Automotive brake systems is usually with a DC motor equipped, which includes a commutator, the corresponding the position of the rotor in an appropriate manner, the armature windings of the Rotor controls so that the motor performs a rotary motion.

Die
Die Aufgabe der vorliegenden Erfindung besteht nun darin, ein Motorpumpenaggregat anzugeben, welches kompakter hergestellt werden kann und gleichzeitig eine hohe Druckaufbaudynamik besitzt.The Object of the present invention is now a motor pump unit to specify which can be made more compact and at the same time has a high pressure build-up dynamics.
Diese Aufgabe wird erfindungsgemäß gelöst durch das Motorpumpenaggregat gemäß Anspruch 1.These The object is achieved by the motor pump unit according to claim 1.
Das mechanische Moment eines Bürstenmotors ist definiert als das Produkt zwischen Strom I und motorspezifischer BEMF-Momentkonstante kT. Die maximal erreichbare Drehzahl stellt sich theoretisch bei I = 0 ein, denn die am Motor angelegte Spannung U ist dann gleich der Generatorspannung E des Motors. Die Spannung E ist definiert als das Produkt aus Drehzahl ω und der motorspezifischen BEMF-Konstante ke. Für ei nen theoretisch angenommenen idealen Motor mit einem Wirkungsgrad von η = 100% würde gelten, dass die Konstante ke gleich der Konstante kT ist. Daraus folgt, dass bei gegebener Versorgungsspannung U nur durch Verringerung von ke bzw. kT eine höhere Leerlaufdrehzahl erreicht werden kann. Es ergibt sich daraus jedoch auch, dass zum Erreichen eines bestimmten Moments ein in Abhängigkeit von der Verminderung von kT höherer Strom aufgewendet werden muss. Wird nun die Konstante ke bzw. kT des Motors im Betrieb geändert, kann eine Anpassung des Motors an die jeweilige Anforderung durchgeführt werden.The mechanical moment of a brush motor is defined as the product between current I and motor-specific BEMF torque constant k T. The maximum achievable speed theoretically sets at I = 0, because the voltage U applied to the motor is then equal to the generator voltage E of the motor. The voltage E is defined as the product of speed ω and the motor-specific BEMF constant k e . For a theoretically assumed ideal motor with an efficiency of η = 100%, it would hold that the constant k e is equal to the constant k T. It follows that at a given supply voltage U higher idle speed can be achieved only by reducing k e or k T. It also follows, however, that in order to achieve a certain moment, a higher current must be used as a function of the reduction of k T. If the constant k e or k T of the motor is changed during operation, an adaptation of the motor to the respective requirement can be carried out.
Das erfindungsgemäße Motorpumpenaggregat umfasst eine elektronische Ansteuerschaltung zur Ansteuerung eines elektrischen, die Pumpe antreibenden Gleichstrommotors. Der Gleichstrommotor umfasst zwei oder mehrere Kommutatorringe und bevorzugt eine entsprechende Anzahl von Bürstenpaaren, welche mit den Kommutatorringen zusammenwirken. Die Kommutatorringe erlauben eine getrennte Bestromung von mindestens zwei Sätzen der Motorwicklungen.The Motor pump unit according to the invention comprises a electronic drive circuit for controlling an electrical, the pump driving DC motor. The DC motor includes two or more commutator rings and preferably a corresponding one Number of pairs of brushes, which with the commutator rings interact. The commutator rings allow separate energization of at least two sets of motor windings.
Das Motorpumpenaggregat umfasst vorzugsweise eine Motoransteuerungsschaltung, mit der die Beschaltung der Bürsten und damit die Bestromung der Motorwicklungssätze im Betrieb umgeschaltet oder angepasst werden können, so dass eine bedarfsgerechte Anpassung des Motormoments und der Nenndrehzahl ermöglicht wird.The Motor pump unit preferably comprises a motor drive circuit, with the wiring of the brushes and thus the energization the motor winding sets switched or adjusted during operation so that a needs-based adaptation of the Engine torque and the rated speed is enabled.
Der Motor weist bevorzugt einen ersten und einen zweiten Satz (und ggf. noch weitere) getrennt bestrombarer Wicklungen auf. Je nach bevorzugter Ausführungsform weisen die Sätze die gleiche Windungszahl oder unterschiedliche Windungszahlen auf.Of the Motor preferably has a first and a second set (and possibly even more) separately energized windings on. Depending on the preferred embodiment the sets have the same number of turns or different Winding numbers on.
Vorzugsweise umfasst das Motorpumpenaggregat eine weitere Elektronik, welche eine Betriebsartenumschaltlogik und/oder einen -algorithmus bereitstellt, mit der/dem unterschiedliche Motorbetriebsmodi in Abhängigkeit von der Anwendung der Pumpe eingestellt werden können. Hierdurch kann eine erste Betriebsart der Pumpe ausgewählt werden, bei der beispielsweise mehr Motorwicklungen bestromt werden als in einer zweiten Betriebsart, wodurch sich ein höheres Motormoment in der ersten Betriebsart ergibt, und zur zeitweisen Erhöhung der Drehzahl in der zweiten Betriebsart nur ein Teil der Motorwicklungen bestromt wird, wodurch sich ein niedrigeres Motormoment ergibt. Auf diese Weise kann die Verlustleistung im Modus für die höhere Nenndrehzahl auf einem vertretbar geringen Maß gehalten werden. Vorteilhafterweise lassen sich somit an sich gegenläufige Motoreigenschaften in einem Motor realisieren.Preferably, the engine pump assembly includes further electronics that provide mode switching logic and / or algorithm that can be used to set different engine operating modes depending on the application of the pump. In this way, a first operating mode of the pump can be selected in which, for example, more motor windings are energized than in a second mode, resulting in a higher engine torque in the first mode, and for temporarily increasing the speed in the second mode, only a portion of the motor windings energized which results in a lower engine torque. In this way, the power loss in the mode for the higher rated speed can be kept at a reasonable low level. Advantageously, can thus be against realize common engine characteristics in a motor.
Die weitere Elektronik umfasst bevorzugt eine Pulsweitenmodulationsschaltung zur Leistungssteuerung des Motors.The Further electronics preferably comprise a pulse width modulation circuit for power control of the motor.
Es ist zweckmäßig, dass im Lastpfad des Motors bestehend aus zumindest einem aktiven Ansteuerhalbleiterelement und wenigstens einer Motorwicklung ein Verpolschutzhalbleiterbauelement vorgesehen ist. Besonders vorteilhaft ist es, wenn einer oder alle notwendigen Verpolschutzhalbleiter im Bereich des Motors angeordnet werden, da im Bereich des Motors eine Kühlung der Bauelemente einfacher möglich ist. Ganz besonders bevorzugt handelt es sich bei den Verpolschutzhalbleiterbauelementen ebenfalls um aktive Halbleiterbauelemente, welche in Abhängigkeit der Taktung der Ansteuerhalbleiterelemente von der PWM-Stufe angesteuert werden.It is expedient that consisting in the load path of the motor of at least one active driving semiconductor element and at least a motor winding a Verpolschutzhalbleiterbauelement provided is. It is particularly advantageous if one or all necessary Reverse polarity protection can be arranged in the area of the motor, as in the engine cooling of the components easier possible is. The polarity reversal protection semiconductor components are also very particularly preferred to active semiconductor devices, which depend on the timing of the drive semiconductor elements driven by the PWM stage become.
Weitere bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels an Hand von Figuren.Further preferred embodiments will be apparent from the dependent claims and the following description of an embodiment Hand of figures.
