Description

Die Erfindung bezieht sich auf einen Verstellantrieb, insbesondere Kraftfahrzeug-Fensterheberantrieb gemäß Oberbegriff des Anspruchs 1; ein derartiger Verstellantrieb ist durch die DE-C2-35 19 056 bekannt.The invention relates to an adjustment drive, in particular motor vehicle window lift drive according to the preamble of claim 1; such an adjustment drive is known from DE-C2-35 19 056.

Bei der durch die DE-C2 35 19 056 bekannten Fensterheber-Antriebseinheit sind ein Schneckenrad als Antriebsrad und eine Seiltrommel als Abtriebsrad sowie ein zwischen beiden zur gegenseitigen Drehmitnahme vorgesehenes gesondertes Zwischenteil auf einem Lagerbolzen drehbar gelagert, der an seinen axialen Enden in Lagerbuchsen gelagert ist, von denen die eine im Topfboden des topfförmigen Getriebegehäuses und die andere in einem ebenen Wandteil befestigt ist, das mit dem Getriebegehäuse unter Zwischenlegung eines ringförmigen Seiltrommel-Gehäuseteils festschraubbar ist, welches im zusammengebauten Zustand der gesamten Antriebseinheit gleichzeitig als Verschluß des ansonsten offenen topfförmigen Getriebegehäuses dient. Zum Zusammenhalt der Bauteile jeder einzelnen Bauteileinheit unter sich sind in der ersten motorseitigen Bauteileinheit lediglich das Schneckenrad auf den Lagerbolzen aufgesteckt und in der abtriebsseitigen Bauteileinheit die Lagerbuchse für den Lagerbolzen mit einem radialen Umfangsbund versehen, zwischen dem und dem ebenen Wandteil sowohl die gesonderte Mitnahmescheibe als auch die Seiltrommel bei konzentrischer Lagerung auf der Lagerbuchse mit einem korrespondierenden radialen Absatz eingepaßt sind.In the window lifter drive unit known from DE-C2 35 19 056, a worm wheel as the drive wheel and a cable drum as the driven wheel, as well as a separate intermediate part provided between the two for the mutual rotational driving, are rotatably mounted on a bearing pin, which is mounted at its axial ends in bearing bushes, one of which is fastened in the pot bottom of the pot-shaped gear housing and the other in a flat wall part which can be screwed to the gear housing with the interposition of an annular cable drum housing part, which in the assembled state of the entire drive unit also serves as a closure of the otherwise open cup-shaped gear housing. To hold the components of each individual component unit together, only the worm wheel is attached to the bearing pin in the first motor-side component unit and the bearing bush for the bearing pin in the output-side component unit is provided with a radial circumferential collar, between which and the flat wall part both the separate drive plate and the cable drum is fitted with a corresponding radial shoulder in the case of concentric storage on the bearing bush.

Durch die DE-A-29 52 408, Fig. 2,3 ist ein Kraftfahrzeug-Fensterheberantrieb mit einem topfförmig abgestuften Getriebegehäuse und einem an dessen offener Seite unter Zwischenlage einer randseitigen Dichtungsscheibe gegenliegenden ebenfalls topfförmig abgestuften Gehäusedeckel bekannt; das Getriebegehäuse ist mit dem einen Ende einer Achse und der Gehäusedeckel ist mit dem anderen Ende dieser Achse unmittelbar anliegend fest verbunden. Ein Schneckenrad in dem Getriebegehäuse erstreckt sich mit einer die Achse direkt umgreifenden Lagerhülse bis radial unterhalb einer im wesentlich innerhalb des Gehäusedeckels angeordneten Seilscheibe, die ihrerseits auf dieser Lagerhülse gelagert ist. Zur Abdichtung zwischen dem Getriebegehäuseteil und dem Seilscheibendeckelteil weist ein einerseits am Schneckenrad und andererseits an einem Kupplungsteil zur Seilscheibe in Drehmitnahme anliegendes Gummiteil axial vorstehende, gegen die Dichtungsscheibe anliegende Dichtlippen auf.From DE-A-29 52 408, Fig. 2.3 is a motor vehicle window lift drive with a cup-shaped stepped gear housing and one on its open side with an intermediate layer an edge-side sealing washer opposite cup-shaped stepped housing cover is known; the gear housing is connected to one end of an axle and the housing cover is firmly connected to the other end of this axle. A worm wheel in the gearbox housing extends with a bearing sleeve directly encompassing the axis to radially below a rope pulley which is arranged essentially within the housing cover and is in turn mounted on this bearing sleeve. For sealing between the gearbox housing part and the cable pulley cover part, a rubber part, which is on the one hand on the worm wheel and on the other hand on a coupling part for the pulley, has axially projecting sealing lips which bear against the sealing washer.

Bei einem durch die DE-A1-34 38 254 bekannten Seilfensterheberantrieb für ein Kraftfahrzeug sind der Getriebeteil und der Seilscheibenteil in einem gemeinsamen Gehäuse untergebracht, das aus zwei halbschalenförmigen, mit ihren offenen Seiten gegeneinander liegenden Gehäusehälften gebildet wird, wobei die eine Gehäusehälfte die von einem angeflanschten Elektromotor angetriebe Schneckenwelle und das damit kämmende Schneckenrad und die andere Gehäusehälfte die vom Seil umschlungene Seilscheibe jeweils topfförmig umgeben.In a cable window lifter drive for a motor vehicle known from DE-A1-34 38 254, the gear part and the cable pulley part are accommodated in a common housing, which is formed from two half-shell-shaped housing halves with their open sides against each other, one housing half surrounding the worm shaft driven by a flanged electric motor and the meshing worm wheel and the other housing half surrounding the rope pulley wrapped in the rope in a pot-shaped manner.

Gemäß Aufgabe vorliegender Erfindung soll ein Verstellantrieb für ein Kraftfahrzeug, insbesondere ein Fensterheberantrieb der eingangs genannten Art geschaffen werden, der sich durch eine verbesserte Montage- und Servicefreundlichkeit, insbesondere hinsichtlich einer einfachen Montage und Demontage der Motorgetriebeeinheit auszeichnet.According to the object of the present invention, an adjustment drive for a motor vehicle, in particular a window lift drive of the type mentioned at the outset, which is characterized by improved assembly and service friendliness, in particular with regard to simple assembly and disassembly of the motor gear unit.

Die Lösung der gestellten Aufgabe gelingt bei einem Verstellantrieb der eingangs genannten Art erfindungsgemäß durch die Lehre des Anspruchs 1. Durch die erfindungsgemäße Konstruktion wird eine vollkommene funktionelle Trennung zwischen Motorgetriebeeinheit einerseits und Seilscheibeneinheit andererseits in der Weise erreicht, daß die Motorgetriebeeinheit unabhängig von der Seilscheibeneinheit z.B. in die Tür eines Kraftfahrzeugs ein-oder ausbaubar ist. Bei der erfindungsgemäßen funktionellen Trennbarkeit zwischen Motorgetriebeeinheit und Seilscheibeneinheit kann mit besonders geringem Bauteile- und Montageaufwand für die beiden Bauteileinheiten gleichzeitig in vorteilhafter Weise eine vollständige Abdichtung der feuchtigkeitsempfindlichen Motorgetriebeeinheit gegenüber der Abtriebseinheit dadurch mit einfachen Mitteln erreicht werden, daß die gleichzeitig direkt zur Drehmitnahme mit der Abtriebsscheibe einsetzbare Antriebsscheibe, d.h. bei einem Fensterheberantrieb das im Getriebegehäuse drehbar gelagerte Schneckenrad, gegen den konzentrisch umgebenden Gehäusedeckel und die im Getriebegehäuse befestigte, die Antriebsscheibe und die Abtriebsscheibe aufnehmende Achse durch Dichtungen, insbesondere O-Ringe, abdichtbar ist.The object is achieved with an adjusting drive of the type mentioned in the invention by the teaching of claim 1. The construction according to the invention achieves a perfect functional separation between the motor gear unit on the one hand and the pulley unit on the other hand in such a way that the motor gear unit independently of the pulley unit, for example in the door of a motor vehicle can be installed or removed. With the functional separability according to the invention between the motor gear unit and the pulley unit, the moisture-sensitive motor gear unit can be sealed off from the output unit in a simple manner, with particularly low component and assembly costs for the two component units, by simple means that at the same time directly for rotary driving with the driven pulley usable drive disk, ie in a window lifter drive the worm wheel rotatably mounted in the gearbox housing can be sealed against the concentrically surrounding housing cover and the axle fastened in the gearbox housing and accommodating the drive disk and the driven disk by seals, in particular O-rings.

Bekannterweise erfolgt die Drehmitnahme zwischen der Antriebsscheibe und der Abtriebsscheibe über an diese angeformte, axial vorstehende Nocken, wobei zur Verhinderung von Stoßbelastungen Dämpfungselemente in Form von Dämpfungsscheiben mit axial offenen Mitnahmetaschen vorgesehen sind, in die die Mitnahmenocken eingreifen. Nach einer ersten Ausgestaltung der Erfindung sind derartige Mitnahmenocken an der Antriebsscheibe vorgesehen und beim Zusammenbau der Bauteileinheiten unter Zwischenlage einer Dämpfungsscheibe in korrespondierende Mitnahmetaschen der Abtriebsscheibe einsteckbar; nach einer zweiten Ausgestaltung der Erfindung sind alternativ zu der vorgenannten Lösung die Mitnahmenocken an der Abtriebsscheibe vorgesehen und beim Zusammenbau der Bauteileinheiten unter Zwischenlage einer Dämpfungsscheibe in korrespondierende Mitnahmetaschen der Antriebsscheibe einsteckbar.As is known, the rotational driving between the drive pulley and the driven pulley takes place via axially projecting cams molded onto them, damping elements in the form of damping pulleys with axially open driving pockets, in which the driving cams engage, are provided to prevent shock loads. According to a first embodiment of the invention, driving cams of this type are provided on the drive pulley and can be inserted into corresponding driving pockets of the driven pulley during assembly of the component units with the interposition of a damping pulley; According to a second embodiment of the invention, as an alternative to the aforementioned solution, the driving cams are provided on the driven pulley and can be inserted into corresponding driving pockets of the driving pulley when a component is being assembled with the interposition of a damping washer.

Zum einfachen, insbesondere durch Handhabungsautomaten mit geringem Aufwand zu bewerkstelligenden Zusammenbau der beiden Bauteileinheiten, ist vorgesehen, daß deren Bauteile im Sinne einer vorzugsweise axialen Steckverbindung zusammenfügbar sind. Eine derartige Steckverbindungstechnik eignet sich insbesondere für die Bauteile der zweiten, u.a. die Seilscheibe aufnehmenden Bauteileinheit. Dazu ist nach einer Ausgestaltung der Erfindung vorgesehen, daß das zweite Gehäuse die Abtriebsscheibe und deren Dämpfungselement und gegebenenfalls die zusätzliche Kupplungsscheibe mit gegenseitigen Rastverschlüssen im Sinne axialer gegenseitiger Steckverbindungen versehen sind.For simple assembly of the two component units, in particular to be accomplished with little effort by handling machines, it is provided that their components can be joined together in the sense of a preferably axial plug connection. Such a connector technology is particularly suitable for the components of the second, including the pulley-receiving component unit. For this purpose, according to one embodiment of the invention, it is provided that the second housing, the output disk and its damping element and, if appropriate, the additional clutch disk are provided with mutual snap locks in the sense of axial mutual plug connections.

Fig. 1 zeigt in einem axialen Längs-Teilschnittbild einen elektromotorischen Kraftfahrzeug-Fensterheberantrieb mit einem nur schematisch angedeuteten Elektromotor 1, dessen verlängerte Rotorwelle als Schneckenwelle 11 in ein an das Gehäuse des Elektromotors 1 angeflanschtes topfförmiges, mit einem Getriebegehäusedeckel 21 verschließbares Getriebegehäuse 2 ragt und ein in diesem auf einer im Getriebegehäuse 2 verankerten Achse 9 drehbar gelagertes Schneckenrad 4 antreibt.1 shows an axial longitudinal partial sectional view of an electromotive motor vehicle window lifter drive with an electric motor 1 which is only indicated schematically, the elongated rotor shaft of which extends as a worm shaft 11 into a cup-shaped gear housing 2 which is flanged to the housing of the electric motor 1 and can be closed with a gear housing cover 21 drives worm wheel 4 rotatably mounted on an axle 9 anchored in gear housing 2.

Das Schneckenrad 4 weist gemäß der Ausgestaltung nach Fig. 2,6 über seinen Umfang verteilt stirnseitig axial vorstehende Mitnahmenocken 41 auf, die unter Zwischenlage einer Dämpfungsscheibe 7 in korrespondierende Mitnahmetaschen einer derart in Drehmitnahme stehenden Seilscheibe 5 axial eingesteckbar sind. Die Seilscheibe 5 ist mit einer Achsbohrung 55 auf der Achse 9 drehbar gelagert und weist an ihrem Außenumfang Seilrillen 54 zur Aufnahme eines hier nicht dargestellten, mit mehreren Windungen die Seilscheibe 5 umschlingenden Seiles auf, dessen Enden durch Seilführungsöffnungen 31 des topfförmigen Seilscheibengehäuses 3 hinein- bzw. herausführbar sind.The worm wheel 4 has, according to the embodiment according to FIG. 2.6, axially protruding driving cams 41 distributed over its circumference on the face side, which can be inserted axially with the interposition of a damping disk 7 into corresponding driving pockets of a rope pulley 5 which is rotatably driven in this way. The rope pulley 5 is rotatably supported on the axis 9 with an axle bore 55 and has on its outer circumference rope grooves 54 for receiving a rope, not shown here, which wraps around the rope pulley 5 with several turns, the ends of which enter and exit through rope guide openings 31 of the pot-shaped rope pulley housing 3 are executable.

Weitere nähere Einzelheiten der beiden Bauteileinheiten werden im folgenden anhand der Figuren 4 bis 6 beschrieben.Further details of the two component units are described below with reference to FIGS. 4 to 6.

Fig. 4 zeigt als wesentliche Bauteile der zweiten Bauteileinheit, die an ihrem Außenumfang mit Seilrillen 54 versehene Seilscheibe 5, die mit der Seilscheibe 5 in Drehmitnahme stehende erste Dämpfungsscheibe 7 und das die Seilscheibe 5 und die Dämpfungsscheibe 7 aufnehmende Seilscheibengehäuse 3. Zur gegenseitigen Verbindung dieser Bauteile zu der in Fig. 5 im zusammenmontierten Zustand gezeigten zweiten Bauteileinheit ist das Seilscheibengehäuse 3 mit einer Bodenöffnung mit einer Rasthinterschneidung 32 versehen, hinter die Rastnasen 52 am freien Ende der Achsbohrung 55 der Seilscheibe 5 beim axialen Zusammenstecken beider Bauteile einrasten kann. Die Rastnasen 52 sind durch einen Axialschlitz 56 im freien Ende der Achsbohrung 55 beim Zusammenstecken mit dem Seilscheibengehäuse radial elastisch wegdrückbar.4 shows, as essential components of the second component unit, the rope pulley 5 provided on its outer circumference with rope grooves 54, the first damping disk 7, which is entrained in rotation with the rope disk 5, and the rope pulley housing 3 receiving the rope pulley 5 and the damping disk 7. For the mutual connection of these Components for the second component unit shown in the assembled state in FIG. 5, the sheave housing 3 is provided with a bottom opening with a catch undercut 32, behind which catches 52 can snap into place at the free end of the axis bore 55 of the sheave 5 when the two components are axially plugged together. The locking lugs 52 can be radially elastically pushed away by an axial slot 56 in the free end of the axle bore 55 when they are plugged together with the sheave housing.

An der rechten Stirnseite der Seilscheibe 5 ist eine nach radial innen vorstehende Rastnase 53 vorgesehen, hinter welche die ebenfalls axial aufsteckbare Dämpfungsscheibe 7 mit einer Rasthinterschneidung 72 elastisch einrastbar ist. Seilscheibe 5, Dämpfungsscheibe 7 und Seilscheibengehäuse 3 sind also in ihrer gegenseitigen Bauteilezuordnung miteinander verbunden.On the right end face of the rope sheave 5 there is a locking lug 53 projecting radially inward, behind which the damping disk 7, which can also be axially plugged in, can be elastically snapped in with a locking undercut 72. Sheave 5, damping sheave 7 and sheave housing 3 are thus interconnected in their mutual component assignment.

Fig. 6 zeigt die fertigmontierte erste Bauteileinheit mit dem topfförmigen Getriebegehäuse 2, der darin befestigten Achse 9, dem auf der Achse 9 drehbar gelagerten, von der Schneckenwelle 11 angetriebenen Schneckenrad 4 und dem das topfförmige Getriebegehäuse verschliessenden und sämtliche Bauteile in ihrer Bauteilzuordnung haltenden Getriebegehäusedeckel 21. Über die Außenstirnseite des Getriebegehäusedeckels 21 ragen, gegen die zweite Bauteileinheit gerichtet, über den Umfang des Schneckenrades 4 verteilt angeordnete axial vorstehende Mitnahmenocken 41 sowie die Achse 9 hervor. Nach einer Ausgestaltung der Erfindung ist der Getriebegehäusedeckel 21 gegenüber dem axial hindurchreichenden Mitnahmeteil des Schneckenrades 4 durch eine Gehäusedichtung 22, insbesondere in Form eines sogenannten O-Ringes und das Schneckenrad 4 selbst mittels einer Achsdichtung 42 gegenüber der Achse 9 vollständig abgedichtet, so daß nach dem gegenseitigen Zusammenbau beider Bauteileinheiten gegebenenfalls von der Seilführung durch die Seilführungsöffnungen 31 in das Seilscheibengehäuse 3 geförderte Feuchtigkeit nicht in die Getriebeeinheit und insbesondere auf dem Umweg über die Getriebeeinheit nicht in die Motoreinheit eindringen kann. In vorteilhafter Weise ist in dem Gehäusedeckel 21 eine umlaufende Führungsnase 23 eingeformt, der im Sinne einer axialen und u.U. auch radialen, d.h. verkantungsfreien Lagesicherung des Schneckenrades 4 eine in dieses eingeformte korrespondierende umlaufende Führungsnut 43 zugeordnet ist; Führungsnase und Führungsnut können auch gegenseitig vertauscht sein.6 shows the fully assembled first component unit with the cup-shaped gear housing 2, the shaft 9 fastened therein, the worm wheel 4 rotatably mounted on the shaft 9 and driven by the worm shaft 11 and the gear housing cover 21 closing the cup-shaped gear housing and holding all components in their component assignment Over the outer end face of the gear housing cover 21, directed against the second component unit, project axially protruding driving cams 41 and the axis 9 distributed over the circumference of the worm wheel 4. According to one embodiment of the invention, the gear housing cover 21 against the axially extending driving part of the worm wheel 4 by a housing seal 22, in particular in the form of a so-called O-ring and the worm wheel 4 itself by means of an axle seal 42 against the axis 9 completely sealed, so that after the mutual assembly of both component units, if necessary, by the cable guide the moisture in the rope guide openings 31 into the rope sheave housing 3 cannot penetrate into the gear unit and in particular cannot penetrate into the motor unit via the gear unit. Advantageously, a circumferential guide lug 23 is formed in the housing cover 21, which is associated with a corresponding circumferential guide groove 43 molded into it in the sense of an axial and possibly also radial, that is to say tilt-free positional securing of the worm wheel 4; Guide nose and guide groove can also be interchanged.

Beim Zusammenbau der beiden Bauteileinheiten werden die axial mittig vorstehenden Mitnahmenocken 41 des Schneckenrades 4 unter Zwischenlage der Dämpfungsscheibe 7 in korrespondierende Mitnahmetaschen 71 der Seilscheibe 5 eingesteckt. Nach dem Zusammenbau beider Bauteileinheiten ist die Seilscheibe 5 entgegen einer radialen Seilzugbelastung in vorteilhafter Weise auf der in die Achsbohrung 55 eingeführten Achse 9 abgestützt.When assembling the two component units, the axially central projecting driving cams 41 of the worm wheel 4 are inserted into corresponding driving pockets 71 of the rope pulley 5 with the damping disk 7 interposed. After the assembly of the two component units, the sheave 5 is advantageously supported against the radial cable pull load on the axis 9 inserted into the axle bore 55.

Fig. 3 zeigt eine Alternativausführung, die sich dadurch von der gemäß Fig. 1,2 bzw. Fig.4 bis 6 unterscheidet, daß die axial vorstehenden Mitnahmenocken 51 an die Seilscheibe 5 angeformt und unter Zwischenlage einer Dämpfungsscheibe 8 in korrespondierende Mitnahmetaschen des dadurch in Drehmitnahme stehenden Schneckenrades 4 eingesteckt. Die Dämpfungsscheibe 8 kann in ähnlicher Weise wie im Fall der ersten Dämpfungsscheibe 7 durch axiale montierbare Verrastung mit dem Schneckenrad 4 verbunden sein.Fig. 3 shows an alternative embodiment, which differs from that according to Fig. 1, 2 or 4 to 6 in that the axially projecting driving cams 51 are integrally formed on the sheave 5 and with the interposition of a damping disk 8 in corresponding driving pockets of the in Rotary driving standing Worm wheel 4 inserted. The damping disk 8 can be connected to the worm wheel 4 in a similar manner as in the case of the first damping disk 7 by means of axially mountable latching.

In vorteilhafter Weise dient beim Zusammenbau der ersten Bauteileinheit mit der zweiten Bauteileinheit der axial vorstehende Achsstummel der Achse 9 nicht nur zur drehbaren Lagerung und radialen Abstützung der Seilscheibe 5, sondern auch zur axial fluchtenden Ausrichtung der gesamten zweiten Bauteileinheit zur ersten Bauteileinheit bei deren gegenseitiger Verbindung. Diese Verbindung kann in üblicher Weise z.B. durch Klammern, Schweißen usw. erfolgen.Advantageously, when the first component unit is assembled with the second component unit, the axially projecting stub axle of the axis 9 serves not only for rotatable mounting and radial support of the rope sheave 5, but also for the axially aligned alignment of the entire second component unit to the first component unit when they are connected to one another. This connection can be e.g. by clamping, welding, etc.
