Elektromotorantrieb, insbesondere Kraftfahrzeug-Fensterheberantrieb Electric motor drive, in particular motor vehicle window lifter drive

Die Erfindung bezieht sich auf einen Verstellantrieb, insbesondere Kraftfahrzeug-Fensterheberantrieb, gemäß Anspruch 1.The invention relates to an adjustment drive, in particular motor vehicle window lifter drive, according to claim 1.

Durch die EP-Al-O 3 94 512, insbesondere FIG 1, ist ein motorischer Fensterheberantrieb mit von einem Kommutatormotor angetriebenem Schneckengetriebe bekannt. Das Motorgehäuse des Kommutatormotors ist an das Getriebegehäuse des Schneckengetriebes angeflanscht; die aus Stahl gefertigte Rotorwelle ist als Getriebewelle bis in das Getriebegehäuse reichend verlängert und dort mit einer eingefrästen Schneckenwelle versehen, die mit einem abtriebsseitigen Schneckenrad kämmt. Der Kommutator sowie das Rotorblechpaket des Kommutatormotors sind in üblicher Weise auf die stählerne Rotorwelle aufge-0 drückt und im Preßsitz auf dieser gehalten.EP-Al-O 3 94 512, in particular FIG 1, discloses a motorized window lifter drive with a worm gear driven by a commutator motor. The motor housing of the commutator motor is flanged to the gear housing of the worm gear; the rotor shaft made of steel is extended as a gear shaft into the gear housing and is provided there with a milled worm shaft that meshes with a worm wheel on the output side. The commutator and the rotor lamination package of the commutator motor are pressed onto the steel rotor shaft in the usual way and held in a press fit.

Der Fertigungs- und Montageaufwand für einen Elektromotor mit zumindest einem auf einer Rotorwelle gehaltenem Rotorblechpaket und bei einem Kommutatormotor gleichartig gehaltenem Kommutatorantrieb kann erfindungsgemäß dadurch wesentlich gemindert werden, daß die Rotorwelle aus einem Kunststoff-Spritzgußteil besteht und das Rotorblechpaket sowie gegebenenfalls auch der Kommutator durch Einspritzen der Rotorwelle in ihre jeweilige Wellenbohrung auf der Rotorwelle gehalten sind. Auf gesonderte, auf die Rotorwelle aufzusteckende Isolierhülsen kann verzichtet werden, die bei einer stählernen, d.h. elektrisch nicht isolierenden Rotorwelle dann notwendig sind, wenn z.B. Gefahr besteht, daß die Leitungsverbindungen zwischen den Lamellen des Kommutators einerseits und den Nuten des Rotorblechpaketes andererseits die Rotorwelle berühren.The manufacturing and assembly costs for an electric motor with at least one rotor core held on a rotor shaft and a commutator drive held in the same way in a commutator motor can be significantly reduced according to the invention by the rotor shaft being made of a plastic injection-molded part and the rotor core and possibly also the commutator being held on the rotor shaft by injecting the rotor shaft into their respective shaft bore. Separate insulating sleeves to be plugged onto the rotor shaft can be dispensed with, which are necessary in the case of a steel, i.e. electrically non-insulating rotor shaft if, for example, there is a risk that the line connections between the laminations of the commutator on the one hand and the grooves of the rotor core on the other hand will touch the rotor shaft.

In vorteilhafter Weise kann beim gleichen Spritzvorgang das Rotorblechpaket auch mit einer Nutisolierung und stirnseitig mit aufgespritzten Isolierendscheiben versehen werden.Advantageously, the rotor core can also be provided with slot insulation and with sprayed-on insulating end disks on the front side during the same spraying process.

In herstellungstechnisch günstiger und aufwandsarmer Weise werden also beim Gegenstand der Erfindung das vorgefertigte Rotorblechpaket sowie der vorgefertigte Kommutator in eine Gießform gelegt, in der auch die Rotorwelle aus Kunststoff spritzgegossen wird, derart daß durch daß Gießen der Rotorwelle das Rotorblechpaket bzw. der Kommutator in einem Arbeitsgang gegeneinander isoliert mit der Rotorwelle im Sinne einer Bauteileinheit untereinander verbindbar ist.In a manner that is technically favorable and inexpensive to manufacture, the prefabricated rotor laminated core and the prefabricated commutator are placed in a mold in which the rotor shaft is also injection molded from plastic, in such a way that by casting the rotor shaft, the rotor laminated core and the commutator can be connected to the rotor shaft in a single operation, insulated from one another, in the sense of a component unit.

Die Erfindung sowie weitere vorteilhafte Ausgestaltungen der Erfindung werden im folgenden anhand eines schematisch dargestellten Ausführungsbeispiels in der Zeichnung näher erläutert; darin zeigen:The invention and further advantageous embodiments of the invention are explained in more detail below using a schematically illustrated embodiment in the drawing, in which:

FIG 1 In einem axialen Längsschnitt eine Rotorwelle mit darauf befestigtem Rotorblechpaket bzw. Kommutator sowie beim Spritzen der Rotorwelle gleichzeitig miteingespritzter Schneckenverzahnung;FIG 1 In an axial longitudinal section, a rotor shaft with a rotor core or commutator attached to it and the worm gearing injected at the same time as the rotor shaft was sprayed;

FIG 2 eine Ansicht gemäß Verlauf II-II in FIG 1; FIG 3 im vergrößerten Ausschnitt den mit der Rotorwelle 5 mechanisch zu verbindenden Kommutator als Einzelteil; FIG 4 die Anordnung gemäß FIG 1 im Schnittverlauf IV-IV.FIG 2 a view according to line II-II in FIG 1; FIG 3 an enlarged detail of the commutator to be mechanically connected to the rotor shaft 5 as a single part; FIG 4 the arrangement according to FIG 1 in section IV-IV.

FIG 1 zeigt eine Rotorwelle 1 eines Kraftfahrzeug-Fensterheberantriebes. In hier nicht näher dargestellter Weise reicht 0 die Rotorwelle 1 mit ihrem rechten Ende in ein Motorgehäuse eines antreibenden Kommutatormotors und mit ihrem linken Ende in ein an das Motorgehäuse angeflanschtes Getriebegehäuse, das ein Schneckengetriebe mit einem abtriebsseitigen Schneckenrad aufnimmt. Die Rotorwelle 1 kann mit an ihren axialen Enden angeformten Anlaufpilzen 1.4 gegen korrespondierende Anlagenflächen des Motorgehäuses bzw. des Getriebe-FIG 1 shows a rotor shaft 1 of a motor vehicle window lifter drive. In a manner not shown in detail here, the rotor shaft 1 extends with its right end into a motor housing of a driving commutator motor and with its left end into a gearbox housing flanged to the motor housing, which accommodates a worm gear with a worm wheel on the output side. The rotor shaft 1 can be pushed against corresponding contact surfaces of the motor housing or the gearbox with starting mushrooms 1.4 formed on its axial ends.

gehäuses axial anlaufen. Die Rotorwelle 1 trägt in ihrem rechten Teil ein hier noch unbewickeltes Rotorblechpaket 2 sowie einen Kommutator 3 mit am Außenumfang einer Preßmasse 3.3 über den Umfang verteilt angeordneten Lamellen 3.2; am linken Ende der Rotorwelle 1 ist eine Getriebeverzahnung 1.1 in Form einer Schneckenwelle vorgesehen, die mit einem hier nicht dargestellten Schneckenrad kämmt.housing. The rotor shaft 1 carries in its right-hand part a rotor laminated core 2, which is not yet wound here, as well as a commutator 3 with lamellae 3.2 distributed around the circumference of a molding compound 3.3; at the left end of the rotor shaft 1 there is a gear toothing 1.1 in the form of a worm shaft, which meshes with a worm wheel (not shown here).

Srfindungsgemäß ist die Rotorwelle 1 mit dem Rotorblechpaket 2 bzw. dem Kommutator 3 dadurch zu einer Bauteileinheit fest verbunden, daß die Rotorwelle 1 als Spritzgußteil in einer Spritzgußform hergestellt wird, in der auch das noch nicht bewickelte Rotorblechpaket 2 bzw. der Kommutator 3 positionsgenau eingelegt sind, derart daß die Rotorwelle 1 durch die Wellenbohrung des Rotorblechpaketes 2 bzw. des Kommutators 3 durchgespritzt und dadurch mit diesen Bauteilen fest verbunden ist.According to the invention, the rotor shaft 1 is firmly connected to the rotor core 2 or the commutator 3 to form a component unit in that the rotor shaft 1 is manufactured as an injection molded part in an injection mold in which the not yet wound rotor core 2 or the commutator 3 are also inserted in a precise position, such that the rotor shaft 1 is injected through the shaft bore of the rotor core 2 or the commutator 3 and is thereby firmly connected to these components.

Nach einer Ausgestaltung der Erfindung ist zwischen dem Ro-0 torblechpaket 2 bzw. dem Kommutator 3 eine zusätzliche formschlüssige Anbindung an die eingespritzte Rotorwelle 1 durch Formschluß-Vorsprünge 2.1;3.1 vorgesehen, die sich in der Kunststoffspritzgußmasse der Rotorwelle 1 verankern.According to one embodiment of the invention, an additional positive connection to the injected rotor shaft 1 is provided between the rotor lamination package 2 and the commutator 3 by means of positive-locking projections 2.1; 3.1, which are anchored in the plastic injection molding compound of the rotor shaft 1.

Der Fertigungs- und Montageaufwand kann dadurch weiter gemindert werden, daß in vorteilhafter Weise beim Spritzgußherstellen der Rotorwelle 1 und dem Spritzgußbefestigen des Rotorblechpaketes 2 bzw. des Kommutaotrs 3 auf dem Umfang der Rotorwelle 1 auch gleichzeitig eine Nutisolierung 1.21 der zur Aufnahme der Rotorwicklung in dem Rotorblechpaket 2 vorgesehenen Nuten 2.1 und/oder ein Aufspritzen von Isolierendscheiben 1.3 auf die Stirnseiten des Rotorblechpaketes 2 vorgesehen wird.The manufacturing and assembly costs can be further reduced by advantageously providing slot insulation 1.21 of the slots 2.1 provided for receiving the rotor winding in the rotor laminated core 2 and/or by spraying insulating end disks 1.3 onto the end faces of the rotor laminated core 2 during the injection molding of the rotor shaft 1 and the injection molding attachment of the rotor laminated core 2 or the commutator 3 on the circumference of the rotor shaft 1.

94 G 3 O 2 8 OE94 G 3 O 2 8 OE

In weiterer Fertigungs- und Montagevereinfachung ist vorgesehen, durch enstprechende Spritzgußformgestaltung beim Spritzgießen der Rotorwelle 1 auch gleichzeitig eine Getriebeverzahnung 1.1, insbesondere in Form einer Schneckenverzahnung, an dem Umfang der Rotorwelle 1 ein- bzw. anzuformen.In order to further simplify production and assembly, it is intended that a gear toothing 1.1, in particular in the form of a worm toothing, be simultaneously formed or molded onto the circumference of the rotor shaft 1 by means of a corresponding injection mold design during injection molding of the rotor shaft 1.

Die über den eigentlichen Elektromotor stirnseitig verlängerte Rotorwelle kann in vorteilhafter Weise auch zur Aufnahme eines Lüfterrades, insbesondere eines Kraftfahrzeug-Ventilators, vorgesehen wird.The rotor shaft, which is extended beyond the actual electric motor at the front, can also advantageously be provided to accommodate a fan wheel, in particular a motor vehicle fan.
