Abstract
Description
Die Erfindung betrifft einen elektrischen Antriebsmotor für ein Kraftfahrzeug zum Einbau in einen Fahrzeugantriebsstrang eines Hybrid- oder eines Elektrofahrzeuges.The invention relates to an electric drive motor for a motor vehicle for installation in a vehicle drive train of a hybrid or an electric vehicle.
Ein derartiger Antriebsmotor ist im Unterschied zu konventionellen Elektromotoren in der Regel ohne ein eigenes Gehäuse und oftmals auch ohne eine eigene Rotor-Lagerstelle ausgeführt, d. h. es werden lediglich eine Stator- und eine Rotorkomponente voneinander getrennt oder alternativ als Liefereinheit beigestellt, wobei im letzten Fall nur eine Transportsicherung für eine vorübergehende Lagezuordnung von Rotor und Statur sorgt. Als Gehäuse solcher Antriebsmotoren dient oftmals ein Getriebegehäuse oder eine Getriebeglocke des Antriebsstranges, wobei auch die Lagerung des Rotors durch die Umgebung eines primären Antriebsmotors, z. B. der Kurbelwelle eines Verbrennungsmotors oder der Eingangswelle eines Gangwechselgetriebes dargestellt wird. Bestimmte Bauformen elektrischer Maschinen erfordern zudem einen Drehstellungsgeber, mit dem eine Winkellage des Rotors bezüglich einer elektrischen Periode des Stators ermittelt wird und auf dessen Basis ein Statorspulensystem mit einem variierenden Strom beaufschlagt werden kann.Such a drive motor is carried out in contrast to conventional electric motors usually without a separate housing and often without its own rotor bearing point, d. H. Only one stator and one rotor component are separated from each other or alternatively provided as a delivery unit, with only one transport lock ensuring a temporary positional assignment of rotor and stature in the latter case. As a housing of such drive motors is often a transmission housing or a bell crank of the drive train, whereby the storage of the rotor by the environment of a primary drive motor, for. B. the crankshaft of an internal combustion engine or the input shaft of a gear change transmission is shown. Certain designs of electrical machines also require a rotary position sensor with which an angular position of the rotor is determined with respect to an electrical period of the stator and on the basis of which a stator coil system can be subjected to a varying current.
Gemäß dem mit der
Die Erfindung stellt sich daher die Aufgabe, den Montageaufwand bei der Integration eines elektrischen Antriebsmotors in einen Fahrzeugantriebsstrang und die Teilevielfalt eines solchen Antriebsmotors zu reduzieren. Gemäß einer weiteren Aufgabe soll bei einem Antriebsmotor die Signalleitung eines Drehstellungsgebers gegenüber elektromagnetischen Wechselfeldern störsicher verlegt werden.The invention therefore has the task of reducing the assembly effort in the integration of an electric drive motor in a vehicle drive train and the variety of parts of such a drive motor. According to a further object, the signal line of a rotary position sensor to electromagnetic alternating fields is to be laid without interference in a drive motor.
Die Erfindung löst die vorstehenden Aufgaben bei einem elektrischen Antriebsmotor der eingangs genannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1.The invention solves the above objects in an electric drive motor of the type mentioned by the characterizing features of claim 1.
Demnach wird ein elektrischer Antriebsmotor für ein Kraftfahrzeug vorgeschlagen, der einen ringförmigen Stator und einen unter Ausbildung eines radialen Luftspaltes koaxial zu diesem gelagerten oder lagerbaren Rotor umfasst und der weiter eine Kühleinrichtung mit einem am Stator verlaufenden Kühlkanal und mit einem Drehstellungsgeber zur Ermittlung einer Drehstellung des Rotors gegenüber dem Stator aufweist. Der Drehstellungsgeber umfasst ein mit dem Rotor umlaufendes Funktionselement und ein zu dem Rotor feststehendes Funktionselement. Gemäß der Erfindung ist vorgesehen, das feststehende Element des Drehstellungsgebers an einem, den Kühlkanal begrenzenden Deckelement anzuordnen.Accordingly, an electric drive motor for a motor vehicle is proposed, which comprises an annular stator and a radial air gap formed coaxially to this stored or storable rotor and further comprising a cooling device with a stator running on the cooling channel and a rotary position sensor for determining a rotational position of the rotor having the stator. The rotary position sensor comprises a functional element revolving around the rotor and a functional element fixed to the rotor. According to the invention, it is provided to arrange the fixed element of the rotary position sensor on a, the cooling channel limiting cover element.
Der Vorteil der vorgeschlagenen Lösung ist zum einen darin zu sehen, dass der zum Betreiben des Antriebsmotors erforderliche Drehstellungsgeber nunmehr auch vollständig zum Lieferumfang des Antriebsmotors zugeordnet ist und dass damit bereits vor dem Einbau des Antriebsmotors eine Funktionsprüfung des Drehstellungsgebers und der damit betreibbaren elektrischen Maschine möglich ist. Zu Weiteren kommt dem Deckelement des Kühlkanals mit der Aufnahme des feststehenden Funktionselements des Drehstellungsgebers eine zusätzliche Funktion zu, wozu dieses Deckelement lediglich einer Modifikation bedarf. Zusätzliche Halterungselemente zur Anordnung des feststehenden Funktionselementes des Drehstellungsgebers erübrigen sich damit, was auch einer möglichst geringen Teileanzahl des gesamten Antriebsmotors zu gute kommt. Die Erfindung kommt insbesondere dann zum Tragen, wenn der elektrische Antriebsmotor als in einen Antriebsstrang zu integrierende Baueinheit gehäuse- und/oder rotorlagerlos ausgeführt ist.The advantage of the proposed solution is firstly that the rotary position sensor required for operating the drive motor is now also completely associated with the delivery of the drive motor and that thus a functional test of the rotary position sensor and the electric machine which can be operated is possible even before the drive motor is installed , In addition, the cover element of the cooling channel with the inclusion of the fixed functional element of the rotary position sensor has an additional function, for which purpose this cover element only requires a modification. Additional support elements for the arrangement of the fixed functional element of the rotary position sensor are unnecessary so that even the smallest possible number of parts of the entire drive motor comes to good. The invention is particularly useful when the electric drive motor is designed as a unit to be integrated into a drive train housing and / or rotor storage.
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den, in den abhängigen Ansprüchen aufgeführten Merkmalen.Advantageous developments and refinements of the invention will become apparent from the features listed in the dependent claims.
Bei einem als Stahlblechteil ausgeführtem Deckelement, welches den radialen Luftspalt des Antriebsmotors radial überdeckt kann eine mit dem feststehenden Funktionselement des Drehstellungsgebers verbundene Signalleitung vorteilhaft auf der dem Rotor und dem Stator abgewandten Axialseite des Deckelements verlegt werden. Auf diese Weise fungiert das Deckelement gleichzeitig als effektive Abschirmung der Signalleitung gegenüber der beim Betreiben der elektrischen Maschine auftretenden elektromagnetischen Wechselfelder.In the case of a cover element designed as a sheet steel part, which radially covers the radial air gap of the drive motor, a signal line connected to the fixed functional element of the rotary position sensor can advantageously be laid on the axial side of the cover element facing away from the rotor and the stator. In this way, the cover element simultaneously acts as an effective shielding of the signal line relative to the electromagnetic alternating fields occurring during operation of the electrical machine.
