FIG 4 die Ausführung gemäß FIG 3 im Schnittverlauf IV-IV. FIG 5,6 jeweils einen Detailausschnitt aus FIG 4.FIG 4 shows the design according to FIG 3 in section IV-IV. FIG 5,6 each show a detailed section from FIG 4.
FIG 1 zeigt in einem axialen Längsschnitt den Prinzipaufbau eines elektromotorischen Kraftfahrzeug-Stellantriebes, der z.B. für einen Fensterheberantrieb bzw. einen Schiebedachantrieb in einem Kraftfahrzeug einsetzbar ist. An die rechte Stirnseite des nur mit seinem Motorgehäuse 1 schematisch angedeuteten Kommutatormotors ist ein Getriebegehäuse 2 angeflanscht, in das die Rotorwelle des Kommutatormotors als Schneckenwelle 11 hineinragt und mit einem in dem Getriebegehäuse 2 drehbar gelagerten Getrieberad 3 kämmt. Wie insbesondere aus der Zusammenschau mit der Schnittdarstellung gemäß FIG 2 ersichtlich, ist der radial äußere Getriebekranz des Getrieberades 3 über federstegartige Speichen 41 als einstückiges Spritzgußteil mit einem Mitnehmer 4 ausgebildet, der mit einem ersten Lagerbereich 42 in einer korrespondierenden Lageraufnahme 22 des Getriebegehäuses 2 und mit einem zweiten Lagerbereich 43 in einer korrespondierende &eegr; Lageraufnahme 221 des Getriebegehäusedeckels 21 drehbar gelagert ist und durch eine Mittelöffnung des Getriebegehäusedeckels 21 mit einem Ende herausragt, das ein Ritzel 5 zur Ankopplung einer Betätigung für die Bewegung eines Kraftfahrzeug-Fensters bzw. eines Kraftfahrzeug-Schiebedaches aufnimmt. Ebenso wie die federstegartigen Speichen 41 ist auch das Ritzel 5 einstückiger Bestandteil des Mitnehmers 4, der zweckmäßigerweise aus einem gute Lagerfunktion übernehmenden Material, insbesondere aus einem entsprechenden Kunststoff oder einem, gegebenenfalls ölgetränkten, Sintermaterial besteht.FIG 1 shows in an axial longitudinal section the basic structure of an electromotive motor vehicle actuator, which can be used, for example, for a window lifter drive or a sunroof drive in a motor vehicle. A gear housing 2 is flanged onto the right-hand end of the commutator motor, which is only schematically indicated by its motor housing 1, into which the rotor shaft of the commutator motor protrudes as a worm shaft 11 and meshes with a gear wheel 3 rotatably mounted in the gear housing 2. As can be seen in particular from the combination with the sectional view according to FIG 2, the radially outer gear ring of the gear wheel 3 is designed via spring-bar-like spokes 41 as a one-piece injection-molded part with a driver 4, which is connected to a first bearing area 42 in a corresponding bearing receptacle 22 of the gear housing 2 and to a second bearing area 43 in a corresponding bearing receptacle 22 of the gear housing 2. Bearing holder 221 of the gearbox housing cover 21 is rotatably mounted and protrudes through a central opening of the gearbox housing cover 21 with one end that accommodates a pinion 5 for coupling an actuation for the movement of a motor vehicle window or a motor vehicle sunroof. Just like the spring-bar-like spokes 41, the pinion 5 is also an integral part of the driver 4, which expediently consists of a material that takes on a good bearing function, in particular of a suitable plastic or a sintered material, possibly impregnated with oil.

Zum Schutz gegen ein Eindringen jeglicher Feuchtigkeit in das Getriebegehäuse und das angeflanschte Motorgehäuse sind ein erster Dichtrand 8 als statische Dichtung im Dichtungsbereich der gegenseitigen Anlage von Getriebegehäuse 2 und Getriebegehäusedeckel 21 sowie ein zweiter Dichtrand 7 als dynamische Dichtung im Bereich der Mittelöffnung des Getriebegehäusedeckels 21 zur Abdichtung gegenüber dem herausragenden Ende des Mitnehmers 4 vorgesehen. Sowohl der erste Dichtrand 8 als auch der zweite Dichtrand 7 sind an den Getriebegehäusedeckel angespritzt und werden beim Zusammenbau selbstdichtend gegen das Getriebegehäuse bzw. den Mitnehmer 4 angedrückt.To protect against the penetration of any moisture into the gearbox housing and the flanged motor housing, a first sealing edge 8 is provided as a static seal in the sealing area of the mutual contact between gearbox housing 2 and gearbox housing cover 21, and a second sealing edge 7 is provided as a dynamic seal in the area of the central opening of gearbox housing cover 21 to seal against the protruding end of driver 4. Both the first sealing edge 8 and the second sealing edge 7 are molded onto the gearbox housing cover and are pressed against the gearbox housing or driver 4 in a self-sealing manner during assembly.
Der erste als statische Dichtung wirkende Dichtrand 8 ist erfindungsgemäß als den Außenrand des Getriebegehäusedeckels 21 umgreifende Flachdichtung derart ausgebildet, daß zur formschlüssigen Verankerung auf gegebenenfalls nicht in jedem Fall das Eindringen von Feuchtigkeit verhindernde Durchbrüche im Getriebegehäusedeckel 21 verzichtet aber andererseits eine formschlüssige Sicherung gegen einen nach radial innen gerichteten Zug der elastischen Flachdichtung gewährleistet werden kann. In vorteilhafter Weise sind jeweils an den ersten Dichtrand 8 bei der Anlage gegen das Getriebegehäuse dichtend preßbare Dichtlippen 81 bzw.82 bzw. an den zweiten Dichtrand 7 gegen den Mitnehmer 4 dichtend preßbare Dichtlippen 71 bzw.72 einstückig angeformt.The first sealing edge 8 acting as a static seal is designed according to the invention as a flat seal that encompasses the outer edge of the gearbox housing cover 21 in such a way that for the positive anchoring, openings in the gearbox housing cover 21, which do not always prevent the ingress of moisture, can be dispensed with, but on the other hand, a positive locking against a radially inward pull of the elastic flat seal can be ensured. In an advantageous manner, sealing lips 81 and 82 that can be pressed to form a seal are formed in one piece on the first sealing edge 8 when it is in contact with the gearbox housing, and sealing lips 71 and 72 that can be pressed to form a seal are formed in one piece on the second sealing edge 7 against the driver 4.
Zur Befestigung zwischen dem Getriebegehäusedeckel 21 und dem Getriebegehäuse 2 sind Verschraubungen vorgesehen, deren Schraubauflagen 212 in vorteilhafter Weise radial außerhalb des ersten Dichtrandes 8 liegen und beim Auftrag des ersten Dichtrandes 8 auf den Getriebegehäusedeckel 21 von einer aufgespritzten Flachdichtung ausgespart bleiben.For fastening between the gear housing cover 21 and the gear housing 2, screw connections are provided, the screw supports 212 of which are advantageously located radially outside the first sealing edge 8 and are left untouched by a sprayed-on flat seal when the first sealing edge 8 is applied to the gear housing cover 21.
Claims (5)
20characterized in that at least one sealing lip (81 or 82) which can be pressed to form a seal when the housing cover (21) rests against the gear housing (2) is formed onto the first sealing edge (8).
