Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Antrieb eines Fahrzeuges mit den Merkmalen des Patentanspruches 1.The present invention relates to a device for driving a vehicle with the features of claim 1.

Aus der DE3542059C1 ist es vorbekannt, eine Achse eines Fahrzeuges mit zwei elektrischen Maschinen anzutreiben. Die elektrischen Maschinen sind jeweils mit einer Gelenkwelle verbunden. Eine Verbindung der beiden elektrischen Maschinen untereinander besteht nicht. Die Gelenkwellen sind wiederum über schaltbare Kupplungen zum Antrieb des Fahrzeuges mit den Antriebsrädern verbunden. Gemäß diesem Stand der Technik ist keine Möglichkeit einer gezielten Beeinflussung der Fahrdynamik des Fahrzeuges beschrieben. Außerdem ist für den Fall, dass eine elektrische Maschine ausgefallen ist, lediglich der Antrieb des Fahrzeuges mit einem der beiden Antriebsräder möglich.From the DE3542059C1 It is already known to drive an axle of a vehicle with two electric machines. The electric machines are each connected to a propeller shaft. There is no connection between the two electrical machines. The propeller shafts are in turn connected via switchable clutches for driving the vehicle with the drive wheels. According to this prior art, no possibility of a specific influencing of the driving dynamics of the vehicle is described. In addition, in the event that an electrical machine has failed, only the drive of the vehicle with one of the two drive wheels possible.

Es ist Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik vorbekannte Vorrichtung derart auszubauen, dass eine gezielte Beeinflussung der Dynamik des Fahrzeuges erfolgen kann und dass, für den Fall, dass eine elektrische Maschine ausgefallen ist, weiterhin der Antrieb des Fahrzeuges mit beiden Antriebsrädern möglich ist.It is an object of the present invention, the previously known from the prior art device to expand such that a targeted influencing the dynamics of the vehicle can be done and that, in the event that an electrical machine has failed, continue the drive of the vehicle with two drive wheels is possible.

Diese Aufgabe wird mittels einer Vorrichtung mit den Merkmalen des Patentanspruches 1 gelöst.This object is achieved by means of a device having the features of claim 1.

Erfindungsgemäß umfasst diese Vorrichtung ein Gehäuse, zwei elektrische Maschinen, ein Differentialgetriebe und zwei Planetengetriebe, wobei die Sonnenräder der Planetengetriebe mit den elektrischen Maschinen verbunden sind, wobei die Hohlräder der Planetengetriebe jeweils mit dem Gehäuse verbunden sind, wobei zwischen den Hohlrädern und den Sonnenrädern der Planetengetriebe Planetenräder angeordnet sind, wobei die Planetenräder jeweils auf einem Planetenträger gelagert sind, wobei die Planetenträger jeweils über eine Kupplung mit dem Differentialgetriebe verbunden oder mit den Abtriebswellen des Differentialgetriebes verbunden werden können oder die Planetenträger weder mit dem Differentialgetriebe, noch mit den Abtriebswellen des Differentialgetriebes verbunden werden können. Erfindungsgemäß vorteilhaft ist es dadurch, dass einerseits die beiden Planetenträger jeweils über eine Kupplung mit dem Differentialgetriebe und insbesondere mit dem Differentialkorb verbunden werden können, möglich, bei gleicher abgegebener Leistung der beiden elektrischen Maschinen im motorischen Betrieb die allgemein bekannte Funktion des Differentialgetriebes beim Antrieb des Fahrzeuges zu nutzen, nämlich der Angleichung der Drehzahlen der Antriebsräder beim Durchfahren einer Kurve, wobei die Fahrdynamik des Fahrzeuges nicht negativ beeinflusst wird. Erfindungsgemäß vorteilhaft ist es dadurch, dass andererseits die Planetenträger jeweils über eine Kupplung mit den Abtriebswellen des Differentialgetriebes verbunden werden können, möglich, durch Bereitstellung unterschiedlicher Drehmomentbeiträge der beiden unabhängig voneinander betriebenen elektrischen Maschinen ein Giermoment auf das Fahrzeug zum Zweck einer Beeinflussung der Fahrdynamik des Fahrzeuges auszuüben, wobei dazu die elektrischen Maschinen mit Mitteln zur Steuerung und Regelung der Dynamik verbunden sind, wobei die Mittel Steuerung und Regelung der Dynamik wiederum mit Mitteln zur Erfassung der Fahrdynamik verbunden sind. Diese Drehmomentbeiträge können positiv oder negativ sein beziehungsweise im Sinne eines Antreibens oder eines Abbremsens, wobei ein positiver Drehmomentbeitrag beim motorischen und ein negativer Drehmomentbeitrag beim generatorischen Betrieb der jeweiligen elektrischen Maschine geleistet wird. Erfindungsgemäß vorteilhaft kann weiterhin bei Ausfall einer der beiden elektrischen Maschinen lediglich die jeweils noch funktionsfähige elektrische Maschine über die Kupplung mit dem Differentialgetriebe und insbesondere mit dem Differentialkorb verbunden werden und die ausgefallene elektrische Maschine kann über die Kupplung von dem Differentialgetriebe getrennt werden, so dass der Antrieb des Fahrzeuges mit nur einer elektrischen Maschine sichergestellt ist, wobei ebenfalls die allgemein bekannte Funktion des Differentialgetriebes beim Antrieb des Fahrzeuges sichergestellt ist. Mit anderen Worten ist es erfindungsgemäß möglich, die beiden Hohlräder unabhängig voneinander mit dem Differentialgetriebe zu verbinden oder zu trennen. Da es weiterhin erfindungsgemäß möglich ist, die Planetenträger weder mit dem Differentialgetriebe, noch mit den Abtriebswellen des Differentialgetriebes zu verbinden, können vorteilhaft die elektrischen Maschinen individuell oder gemeinsam vollständig mit dem Antrieb gekoppelt oder von dem Antrieb des Fahrzeuges entkoppelt werden. Handelt es sich beispielsweise um ein Fahrzeug mit zwei Achsen, wobei eine Achse mittels einer Verbrennungskraftmaschine und eine Achse, wie vorstehend beschrieben, mit zwei elektrischen Maschinen angetrieben wird, dann kann durch eine solche Neutralstellung die gesamte Achse abgekoppelt werden und der Antrieb des Fahrzeuges allein mit der verbleibenden Achse erfolgen. Mittels der Kupplungen ist es außerdem erfindungsgemäß vorteilhaft möglich, dadurch die Dynamik und insbesondere die Querdynamik des Fahrzeuges zu beeinflussen, in dem mindestens eine der beiden Kupplungen schlupfend betrieben wird, so dass unterschiedliche Drehmomentbeiträge an beiden Antriebsrädern des Fahrzeuges erzeugt und somit ein Giermoment auf das Fahrzeug ausgeübt werden kann.According to the invention, this device comprises a housing, two electric machines, a differential gear and two planetary gears, wherein the sun gears of the planetary gear are connected to the electric machines, wherein the ring gears of the planetary gear are respectively connected to the housing, wherein between the ring gears and the sun gears of the planetary gear Planet wheels are arranged, wherein the planet gears are each mounted on a planet carrier, wherein the planet carrier can be connected in each case via a clutch to the differential gear or connected to the output shafts of the differential gear or the planet carrier are connected to neither the differential gear, nor with the output shafts of the differential gear can. According to the invention it is advantageous in that on the one hand the two planet carriers can be connected via a clutch to the differential gear and in particular to the differential carrier, possible at the same output power of the two electric motors in the engine operation, the well-known function of the differential gear when driving the vehicle to use, namely the approximation of the rotational speeds of the drive wheels when driving through a curve, the driving dynamics of the vehicle is not adversely affected. According to the invention it is advantageous in that on the other hand, the planet carrier can be connected in each case via a clutch to the output shafts of the differential gear, possible to exert a yaw moment on the vehicle for the purpose of influencing the driving dynamics of the vehicle by providing different torque contributions of the two independently operated electric machines , to which the electrical machines are connected to means for controlling and regulating the dynamics, wherein the means for controlling and regulating the dynamics are in turn connected to means for detecting the driving dynamics. These torque contributions can be positive or negative or in the sense of driving or braking, with a positive torque contribution being made to the motor and a negative torque contribution during regenerative operation of the respective electrical machine. According to the invention can continue to be connected in case of failure of one of the two electric machines only the still functional electric machine via the clutch to the differential gear and in particular to the differential carrier and the failed electric machine can be separated via the clutch of the differential gear, so that the drive the vehicle is ensured with only one electric machine, which also ensures the well-known function of the differential gear in the drive of the vehicle. In other words, it is inventively possible to connect the two ring gears independently of each other with the differential gear or separate. Since it is still possible according to the invention to connect the planet carrier neither with the differential gear, nor with the output shafts of the differential gear, advantageously the electric machines can be individually or jointly completely coupled to the drive or decoupled from the drive of the vehicle. If, for example, a vehicle with two axles, one axle being driven by means of an internal combustion engine and one axle, as described above, with two electric machines, then by such a neutral position the entire axle can be uncoupled and the drive of the vehicle alone with the remaining axis. By means of the clutches, it is also advantageously possible according to influence the dynamics and in particular the transverse dynamics of the vehicle, in which at least one of the two clutches is slipping operated, so that generates different torque contributions to both drive wheels of the vehicle and thus a yaw moment on the vehicle can be exercised.
