Description
Die Erfindung betrifft eine Antriebsanordnung für ein Kraftfahrzeug. Ferner betrifft die Erfindung ein Verfahren zum Betreiben der zuvor genannten Antriebsanordnung.The invention relates to a drive arrangement for a motor vehicle. Furthermore, the invention relates to a method for operating the aforementioned drive arrangement.
Um den Strom- bzw. Spannungsbedarf von elektrischen Nebenaggregaten in einem Kraftfahrzeug zu decken, wird dem Drehstromgenerator in der Regel ein zeitlich getakteter Erregerstrom zugeführt. Hierbei wird beispielsweise bei einer ersten, niedrigen Generatordrehzahl der Erregerstrom in festgelegten zeitlichen Abständen von einem Regler so ein- bzw. ausgeschaltet, dass sich ein bestimmter, erster mittlerer Erregerstrom bei einer konstanten Bordspannung einstellt. Damit bei einer zweiten, höheren Generatordrehzahl die für das Bordnetz des Kraftfahrzeuges zulässige Bordspannung auf ihren Sollwert geregelt wird, verändert der Regler das Taktsignal dahingehend, dass die ausgeschalteten Zeitanteile zunehmen und sich ein zweiter, mittlerer Erregerstrom einstellt, welcher niedriger ist als der erste. Infolgedessen bleibt die von dem Erregerstrom und der Drehzahl abhängige, in dem Generator induzierte Bordspannung konstant.In order to cover the current or voltage requirement of electrical ancillaries in a motor vehicle, the alternator is usually fed a timed excitation current. In this case, for example, at a first, low generator speed, the exciter current is switched on or off at fixed time intervals by a controller in such a way that a specific, first average exciter current sets at a constant on-board voltage. So that at a second, higher generator speed, the onboard electrical system of the motor vehicle permissible on-board voltage is controlled to its desired value, the controller changes the clock signal to the effect that the off-time components increase and a second, middle excitation current sets, which is lower than the first. As a result, the on-board voltage induced by the excitation current and the speed, which is induced in the generator, remains constant.
Die
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Antriebsanordnung mit einem Nebenaggregat und ein Verfahren zum Betreiben der Antriebsanordnung zu schaffen, wobei das Verfahren einen bedarfsgerechten Antrieb der Antriebsanordnung, insbesondere des Nebenaggregats ermöglichen soll.The object of the present invention is to provide a drive assembly with an accessory and a method for operating the drive assembly, the method should enable a demand-driven drive the drive assembly, in particular the auxiliary unit.
Die erfindungsgemäße Antriebsanordnung für ein Kraftfahrzeug umfasst einen Antriebsmotor, eine elektrische Maschine, ein Nebenaggregat sowie ein dazwischen angeordnetes Planetengetriebe, wobei das Planetengetriebe einen drehbar an einem Steg gelagerten und radial zwischen einem Hohlrad und einer Sonne angeordneten Planetensatz aufweist, wobei das Hohlrad zumindest mittelbar mit dem Antriebsmotor verbunden ist, wobei ferner die Sonne zumindest mittelbar mit der elektrischen Maschine verbunden ist, und wobei das Nebenaggregat zumindest mittelbar mit dem Steg verbunden ist, und wobei der Steg über ein Schaltelement stationär festlegbar ist, um mindestens drei Betriebsstrategien für die Antriebsanordnung zu realisieren. Vorzugsweise ist das Schaltelement als Kupplung, Bremse oder Freilaufvorrichtung ausgebildet.The drive assembly according to the invention for a motor vehicle comprises a drive motor, an electric machine, an accessory and a planetary gear arranged therebetween, wherein the planetary gear has a rotatably mounted on a web and arranged radially between a ring gear and a sun planetary gear set, wherein the ring gear at least indirectly with the Drive motor is connected, further wherein the sun is at least indirectly connected to the electric machine, and wherein the auxiliary unit is at least indirectly connected to the web, and wherein the web via a switching element is fixed stationary to realize at least three operating strategies for the drive assembly. Preferably, the switching element is designed as a clutch, brake or freewheel device.
Mit anderen Worten ermöglicht die Kopplung über das Planetengetriebe zwischen dem Antriebsmotor, der elektrischen Maschine und dem Nebenaggregat in Abhängigkeit der Schaltstellung des Schaltelements einen Betrieb der Antriebsanordnung mit mindestens drei, vorzugsweise vier Betriebsstrategien. Insbesondere ist der Steg über ein Schaltelement stationär an einem Gehäuse, einem Motorblock oder einer Karosserie des Kraftfahrzeugs festlegbar.In other words, the coupling via the planetary gear between the drive motor, the electric machine and the auxiliary unit depending on the switching position of the switching element allows operation of the drive assembly with at least three, preferably four operating strategies. In particular, the web is fixed via a switching element to a housing, an engine block or a body of the motor vehicle.
Gemäß der ersten Betriebsstrategie wird ein Schaltelement geöffnet und die elektrische Maschine sowie das Nebenaggregat werden von einem Antriebsmotor betrieben. Gemäß der zweiten Betriebsstrategie wird das Schaltelement geöffnet und das Nebenaggregat wird von der elektrischen Maschine und dem Antriebsmotor betrieben. Gemäß der dritten Betriebsstrategie wird das Schaltelement geschlossen und die elektrische Maschine wird von dem Antriebsmotor betrieben. Gemäß der vierten Betriebsstrategie wird das Schaltelement geöffnet und das Nebenaggregat wird von der elektrischen Maschine betrieben. Mithin wird in der vierten Betriebsstrategie die Antriebsmaschine ausgeschaltet.According to the first operating strategy, a switching element is opened and the electric machine and the auxiliary unit are operated by a drive motor. According to the second operating strategy, the switching element is opened and the accessory is operated by the electric machine and the drive motor. According to the third operating strategy, the switching element is closed and the electric machine is operated by the drive motor. According to the fourth operating strategy, the switching element is opened and the accessory is operated by the electric machine. Thus, in the fourth operating strategy, the prime mover is switched off.
Vorzugsweise ist das Nebenaggregat als Kältemittelverdichter ausgebildet. Insbesondere ist der Kältemittelverdichter ein Axialkolbenverdichter, der unabhängig von einer Antriebsdrehzahl, sein Drehmoment durch eine Verstellung einer Taumelscheibe variabel einstellt. Mithin erfolgt über eine Verstellung der Taumelscheibe die Einstellung des Kolbenhubs des Axialkolbenverdichters.Preferably, the auxiliary unit is designed as a refrigerant compressor. In particular, the refrigerant compressor is an axial piston compressor which variably adjusts its torque by adjusting a swash plate independently of a driving speed. Thus, adjustment of the swashplate adjusts the piston stroke of the axial piston compressor via an adjustment of the swashplate.
Ferner bevorzugt ist die elektrische Maschine als riemengetriebener Starter-Generator ausgebildet. Mithin dient der riemengetriebene Starter-Generator als Starter für den Antriebsmotor und als Lichtmaschine zur Erzeugung von elektrischer Energie. Ferner wird der riemengetriebener Starter-Generator auch zum Betrieb des Nebenaggregats verwendet. Insbesondere ist der riemengetriebene Starter-Generator dazu vorgesehen, mit einer positiven und negativen Drehzahl sowie mit einem positiven und negativen Drehmoment betrieben zu werden.Further preferably, the electric machine is designed as a belt-driven starter generator. Thus, the belt-driven starter-generator serves as a starter for the drive motor and as an alternator for generating electrical energy. Furthermore, the belt-driven starter-generator is also used to operate the accessory. In particular, the belt-driven starter-generator is intended to be operated with a positive and negative rotational speed and with a positive and negative torque.
Des Weiteren bevorzugt ist das Hohlrad über einen Riementrieb mit dem Antriebsmotor verbunden. Ebenfalls bevorzugt ist der Steg über einen Riementrieb mit dem Nebenaggregat verbunden. Ferner ist auch ein koaxialer Aufbau von elektrischer Maschine und Nebenaggregat denkbar. Beispielsweise kann eine Antriebswelle der elektrischen Maschine durch ein Gehäuse des Nebenaggregats mittels Sonne angetrieben werden. Vorzugsweise weist der jeweilige Riementrieb einen jeweiligen Keilrippenriemen auf. Furthermore, the ring gear is preferably connected to the drive motor via a belt drive. Also preferably, the web is connected via a belt drive with the accessory. Furthermore, a coaxial construction of electrical machine and auxiliary unit is conceivable. For example, a drive shaft of the electric machine can be driven by a housing of the auxiliary unit by means of the sun. The respective belt drive preferably has a respective V-ribbed belt.
