Description

Die Erfindung betrifft einen Fensterheber- bzw. Schiebedachantrieb für ein Kraftfahrzeug, gemäß oberbegriff des Patentanspruchs 1, siehe DE-A- 19 752 973.The invention relates to a window lifter or sunroof drive for a motor vehicle, according to the preamble of claim 1, see DE-A-19 752 973.

Durch die EP 0 360 911 B1 bzw. die GB 2 289 351 A bzw. die DE 92 09 929 U1 sind Verstellantriebe, insbesondere Kraftfahrzeug-Fensterheberantriebe, bekannt, bei denen ein Schließteil, insbesondere eine Kraftfahrzeug-Fensterscheibe, fremdkraftbetätigt durch einen Elektromotor zwischen einer Öffnungsstellung einerseits und einer Schließstellung andererseits verstellbar ist.Through EP 0 360 911 B1 or GB 2 289 351 A or DE 92 09 929 U1 are adjustment drives, in particular motor vehicle window lift drives, known where a Closing part, in particular a motor vehicle window pane, powered by an electric motor between one Open position on the one hand and a closed position on the other hand is adjustable.

In dem Antriebsstrang zwischen dem Elektromotor und dem Schließteil ist zumindest eine Übersetzung in Form eines Getriebes und/oder eines Seilantriebes bzw. eines Scherenheberantriebes vorgesehen; bei einem Seilantrieb wird das Schließteil durch ein Seil bewegt, das seinerseits durch Umschlingen oder Auf- bzw. Abwickeln von einer von dem Antriebsmotor in Drehbewegung versetzten Seilantriebs-Trommel angetrieben wird.In the drivetrain between the electric motor and the Locking part is at least a translation in the form of a gear and / or a cable drive or a scissor lift drive intended; in the case of a cable drive, the closing part moved by a rope, which in turn by looping or winding or unwinding one of the drive motor in Rotational movement offset driven cable drive drum becomes.

Durch die DE 197 52 973 A1 ist eine Fensterstellvorrichtung mit einem Seilantrieb mit einem auf einer Walze mit Spiralrillen auf- bzw. abgewickeltem Seil bekannt, wobei zur Vermeidung einer Schlaffheit bzw. Überspannung des Seiles die Walze aus zwei axial hintereinander angeordneten Walzenteilen zusammengesetzt ist, von denen jeder eine Spiralrille aufweist, deren Tiefe sich zum axial äußeren Ende hin vergrößert. DE 197 52 973 A1 is a window actuating device with a rope drive with one on a roller with spiral grooves wound or unwound rope known, to avoid a slackness or tension of the rope Roll consisting of two roll parts arranged axially one behind the other is composed, each of which has a spiral groove, whose depth increases towards the axially outer end.

Sowohl beim Anfahren aus der Öffnungs-Ruhestellung als beim Einfahren in die mit reibbehafteten Dichtungen versehene Schließstellung wird von dem Elektromotor eine erhöhte Leistung verlangt, für die dieser ausgelegt sein muß; diese erhöhte Leistung erschwert jedoch die Einhaltung von strengen Vorschriften eines Einklemmschutzes, bei dem, insbesondere bei Annäherung an die Schließstellung, die Bewegung des Schließteils in kürzester Zeit abbremsbar sein muß, wenn ein Hindernis die weitere Schließbewegung hemmt.Both when starting from the open rest position and when Drive into the one with friction seals The electric motor increases the closed position demands for which this must be designed; this increased However, performance complicates compliance with strict Anti-trap regulations, in particular when approaching the closed position, the movement of the Locking part must be able to be braked in the shortest possible time if a Obstacle inhibits the further closing movement.

Gemäß Aufgabe vorliegender Erfindung soll bei guter Auslastung des Antriebsmotors ein sicherer Einklemmschutz gewährleistbar sein.According to the object of the present invention, the capacity should be good safe trapping protection of the drive motor can be guaranteed his.

Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch die Lehre des Anspruchs 1.This object is achieved according to the invention by Teaching of claim 1.

Aufgrund der erfindungsgemäßen veränderlichen Übersetzung, im Sinne einer über den gesamten Stellwegbereich des Schließteils konstanten Belastung des Antriebsmotors, muß einerseits dieser nicht - wie bei konstanter Übersetzung erforderlich - entsprechend der jeweils nur kurzfristig für das Einfahren in die reibungsbelastete abgedichtete Schließstellung notwendigen erhöhten Leistung dimensioniert werden und ist andererseits trotz bei einer Schließbewegung anfänglich hoher Schließgeschwindigkeit durch die anschließende wegen der erfindungsgemäß erhöhten Übersetzung geringere Geschwindigkeit und damit geringere beschleunigte träge Masse eine leichtere und schnellere, für einen Einklemmschutz vorteilhafte Abbremsmöglichkeit des Schließteils gewährleistet.Due to the variable translation according to the invention, in the sense of an entire travel range the closing part constant load of the drive motor, on the one hand, this does not have to - as with constant Translation required - according to each one only sealed at short notice for entering the friction-loaded Dimensioned closed position necessary increased power on the other hand and is despite a closing movement initially high closing speed due to the subsequent because of the increased translation according to the invention lower speed and therefore less accelerated inert mass a lighter and faster, for a pinch protection advantageous braking possibility of the closing part guaranteed.

Eine für einen üblichen Kraftfahrzeug-Fenstheberantrieb vorteilhafte veränderliche Übersetzung weist in diesem Sinne eine gegenüber dem übrigen Bereich erhöhte Übersetzung bei Annäherung an die Schließstellung auf; ist von einer Verspannung der Führungs- und Halterungsaufnahme der Fensterscheibe in dem Türrahmen bei Einfahren in die Öffnungsstellung auszugehen, wird vorteilhaft auch für das Anfahren aus der Öffnungsstellung eine erhöhte Übersetzung und damit eine Entlastung und somit über den Gesamt-Stellbereich bessere Auslastung des Antriebsmotors vorgesehen. Eine höhere Übersetzung außerhalb des Schließstellungs- bzw. Öffnungsstellungsbereichs empfiehlt sich bei besonderen Lastanforderungen an den Antriebsmotor, z.B. bei stark gekrümmter Scheibenführung mit entsprechend hoher Reibwiderständen.An advantageous one for a conventional motor vehicle window lift drive changeable translation points in this sense a higher translation than the rest of the range when approaching the closed position; is of a bracing of the guide and bracket receptacle Window pane in the door frame when moving into the open position going out is also advantageous for starting from the open position an increased translation and thus a relief and thus over the entire adjustment range better utilization of the drive motor is provided. A higher one Translation outside the closed position or open position range is recommended for special load requirements to the drive motor, e.g. with a strongly curved disc guide with correspondingly high frictional resistances.

Bei einem Stellantrieb mit einem Seilantrieb im Antriebsstrang zwischen dem Antriebsmotor und dem Schließteil kann die erfindungsgemäß spezifische veränderliche Übersetzung auf besonders einfache Weise dadurch erreicht werden, daß die das Seil bzw. die Seilenden durch Umschlingung bzw. Ab- und Aufwicklung antreibende Seilantriebs-Trommel über ihre axiale Länge mit spiralförmig angeordnetem Seilrinnenverlauf versehen ist, über den das Seil bzw. die Seilenden mit der antriebsübertragenden Umschlingung bzw. Auf- und Abwicklung bei Antrieb der Seilantriebs-Trommel axial fortschreitend antreibbar sind und durch deren veränderlichen Seilrinnendurchmesser die jeweilige erfindungsgemäße Übersetzung umsetzbar ist; der Wechsel zwischen in diesem Sinne unterschiedlichen Seilrinnendurchmessern kann mehr oder weniger stetig, u.U. auch unstetig erfolgen.For an actuator with a cable drive in the drive train can between the drive motor and the closing part the variable translation specific to the invention can be achieved in a particularly simple manner in that the Rope or the rope ends by looping or unwinding and winding driving rope drive drum over its axial Provide the length with a spiral cable tray over which the rope or the rope ends with the drive transmitting Wrapping or winding and unwinding at Drive of the cable drive drum axially progressively drivable are and due to their variable rope trough diameter the respective translation according to the invention can be implemented is; the change between different in this sense Cable tray diameters can be more or less constant, possibly also occur discontinuously.

FIG 4-9
in axial or in front view, an axially respectively cylindrical rope drive drum with corresponding to the positions of the motor vehicle window according to FIG 1-3, in the sense of a variable translation according to the invention different rope trough diameters and each with a developable or a windable rope end.

FIG 1 - 3 zeigen drei verschiedene Stellungen einer in einem Kraftfahrzeug-Türrahmen 7 durch einen Seilantrieb 3;4;5 zwischen einer unteren Öffnungsstellung gemäß FIG 1 über eine mittlere Öffnungsstellung gemäß FIG 2 bis in eine Schließstellung gemäß FIG 3 auf- und abbewegbaren Kraftfahrzeug-Fensterscheibe 2. Zum Antrieb des fremdkraftbetätigten Fensterhebers ist ein Elektromotor 1 vorgesehen, der - wie z.B. aus der GB 2 289 351 A bekannt - über ein Schneckengetriebe eine Seiltrommel 3 bzw.4 des Seilantriebes zur Auf- bzw. Abbewegung der Kraftfahrzeug-Fensterscheibe 2 antreibt; dazu werden durch Auf- bzw. Abwicklung bzw. durch Umschlingung von der Seiltrommel 3 bzw.4 ein Seil 5 bzw. Seilenden 5.1;5.2 bewegt, die über Umlenkrollen 6.1 bzw.6.2 eines Führungsgestänges 6 an die Kraftfahrzeug-Fensterscheibe 2 angelenkt sind und diese auf- bzw. abbewegen.FIGS 1-3 show three different positions one in one Motor vehicle door frame 7 by a cable drive 3; 4; 5 between a lower open position according to FIG 1 via a middle open position according to FIG 2 to a closed position 3 up and down motor vehicle window pane 2. To drive the power window an electric motor 1 is provided which, e.g. out GB 2 289 351 A is known - via a worm gear Rope drum 3 or 4 of the rope drive for up and down movement the motor vehicle window pane 2 drives; to be by winding or unwinding or by wrapping the Rope drum 3 or 4 moves a rope 5 or rope ends 5.1; 5.2, via guide rollers 6.1 or 6.2 of a guide linkage 6 are hinged to the motor vehicle window pane 2 and these move up or down.

Die erfindungsgemäße veränderliche Übersetzung durch entsprechende konstruktiv einfache Ausbildung der jeweiligen Seiltrommel 3 bzw.4 wird im folgenden anhand von Ausführungsbeispielen mit einer durchmesserabgesetzten zylindrischen Seiltrommel 3 gemäß FIG 4 - 9 erläutert, wobei die von der Seiltrommel 3 bzw. 4 abgehenden Seilenden 5.1 bzw.5.2 des Seiles 5 in den unterschiedlichen Darstellungen gemäß FIG 4 - 9 den unterschiedlichen Stellweg-Darstellungen der Kraftfahrzeug-Fensterscheibe 2 gemäß FIG 1 - 3 zuzuordnen sind. The variable translation according to the invention by appropriate simple construction of the respective rope drum 3 and 4 will be described in the following using exemplary embodiments with a diameter-reduced cylindrical rope drum 3 according to FIGS. 4-9, the cable drum 3 or 4 outgoing rope ends 5.1 or 5.2 of the rope 5 in the different representations according to FIGS. 4-9 different travel representations of the motor vehicle window 2 according to FIGS. 1-3.

FIG 4 - 9 zeigen jeweils rechts in axialer Seitenansicht und links in axialer Stirnansicht eine abschnittsweise zylinderförmige Seiltrommel 3 mit axial über ihren Umfang spriralförmig verlaufenden Seilrillen 3.1. Die Seilrillen 3.1 weisen an ihren beiden axialen Enden im Sinne einer gegenüber dem übrigen Bereich erhöhten Übersetzung einen geringeren Durchmesser auf. Auf die Seiltrommel 3 sind in axialem Abstand je ein auf- bzw. abwickelbares Seil 5;5 aufgewickelt, deren eines Ende, z.B. stirnseitig, auf der Seiltrommel 3 befestigt ist und deren anderes Seilende 5.1 bzw.5.2 zu Anlenkpunkten der Kraftfahrzeug-Fensterscheibe 2 führt. Bei einer Drehung der Seiltrommel 3 wird das eine dieser zur Kraftfahrzeug-Fensterscheibe 2 führenden Seilenden aufgewickelt und das andere Seilende abgewickelt; dadurch ergibt sich eine Auf- bzw. Abbewegung der Kraftfahrzeug-Fensterscheibe 2 in dem Führungsgestänge 6 bzw. in dem Kraftfahrzeug-Fensterrahmens 7.FIGS. 4-9 each show on the right in an axial side view and on the left in the axial end view a cylindrical section Rope drum 3 with a spiral shape axially over its circumference running rope grooves 3.1. The rope grooves 3.1 instruct their two axial ends in the sense of one compared to the rest Area increased translation a smaller diameter on. On the cable drum 3 are each in an axial distance windable or unwound rope 5; 5 wound, one of which End, e.g. at the end, on which the cable drum 3 is fastened and their other rope end 5.1 or 5.2 to articulation points of the Motor vehicle window 2 leads. When the Rope drum 3 is one of them to the motor vehicle window pane 2 leading rope ends coiled and the other End of rope unwound; this results in an up and down movement the motor vehicle window pane 2 in the guide linkage 6 or in the motor vehicle window frame 7.

Nach einer fertigungstechnisch vorteilhaften Ausgestaltung der Erfindung ist nunmehr eine unterschiedliche Übersetzung an beiden axialen Enden der Seiltrommel 3 dadurch vorgesehen, daß der Durchmesser der Seilrillen 3.1 im Sinne einer erhöhten Übersetzung kleiner ist als im axialen Mittelbereich der Seiltrommel 3.According to an advantageous embodiment in terms of production technology the invention is now a different translation provided at both axial ends of the cable drum 3, that the diameter of the rope grooves 3.1 in the sense of an increased Gear ratio is smaller than in the axial central area of the Rope drum 3.

Es dürfte ersichtlich sein, daß aufgrund der bei Einfahren in die stärker reibbelastete Schließstellung höheren Übersetzung der Antriebsmotor nicht mehr durch die dadurch gegebene Maximalbelastung überdimensioniert werden muß und daß außerdem aufgrund der geringeren Geschwindigkeit bei Annäherung an die Schließstellung eine, insbesondere bei Gegenlage eines Hemmnisses, notwendige schnelle Einklemmschutz-Abbremsung vereinfacht ist.It should be apparent that due to the when entering the more frictionally loaded Closing position higher gear ratio of the drive motor is not more oversized by the resulting maximum load must be and that also because of the lesser Speed when approaching the closed position one, in particular if there is an obstacle rapid anti-trap braking is simplified.
