Abstract
Die Erfindung betrifft einen Stellantrieb umfassend einen Motor 1 mit Motorwelle, Ritzel 2, zwei kämmenden Doppelzahnrädern 3, 4 und einem Planetengetriebe 11 mit jeweils zueinander parallel längs einer Linie L versetzen Drehachsen I, II, III im Gehäuse 8, wobei eine Planetengetriebeachse mit einer Abtriebsachse sowie der Drehachse vom abtriebsseitigen Doppelzahnrad 4 übereinstimmt, und wobei die Drehachse II vom motorseitigen Doppelzahnrad 3 mit definiertem Achsabstand zwischen Motorwellenachse I und Planetengetriebeachse III vorliegt, sowie mit wenigstens einem Gehäusedeckel 12.Der Erfindung liegt die Aufgabe zugrunde, einen neuartig stabil und verbessert assemblierbaren Stellantrieb zu schaffen, der eine besonders kompakte Bauweise zur Verwendung in Kraftfahrzeugen mit begrenztem Bauraum ermöglicht.Die Aufgabe wird gelöst, indem die Drehachsen II, III der beiden Doppelzahnräder 3,4 einerseits im Gehäusedeckel (12) und andererseits im Gehäuse (8) unmittelbar lösbar gesteckt aufgenommen sind.The invention relates to an actuator comprising a motor 1 with motor shaft, pinion 2, two meshing double gears 3, 4 and a planetary gear 11 with each parallel to a line L offset axes of rotation I, II, III in the housing 8, wherein a planetary gear axis with an output axis and the axis of rotation of the output side double gear 4 coincides, and wherein the axis of rotation II of the motor-side double gear 3 with defined center distance between the motor shaft axis I and planetary gear III exists, as well as with at least one Gehäusedeckel 12.Der invention is based on the object, a novel stable and improved assemblable actuator The object is achieved by the axes of rotation II, III of the two double gears 3.4 on the one hand in the housing cover (12) and on the other hand gestec in the housing (8) gestec kt are included.
Description
Die Erfindung bezieht sich auf einen Stellantrieb nach den Merkmalen vom Oberbegriff vom Patentanspruch 1.The invention relates to an actuator according to the features of the preamble of claim 1.
Die
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, einen stabilen, laufruhigen und rationell verbesserten Stellantrieb unter neuartiger sowie präziser und einfach montierbarer Definition seiner Getriebelagerung vorzulegen, welcher zudem eine besonders kompakte Bauweise zwecks Verwendung in Kraftfahrzeugen mit begrenztem Einbauraum ermöglicht.The invention is based on the object to provide a stable, smooth and rationally improved actuator under novel and precise and easy montierbarer definition of its transmission mounting, which also allows a particularly compact design for use in motor vehicles with limited installation space.
Erfindungsgemäß wird die Aufgabe anhand von einem besonderen Stellantrieb wie auch anhand von einem besonderen Montageverfahren in aufgelöster Bauweise/Bestückung erfüllt. All dies erfolgt unter besonderer Verdichtung, mit Verzicht auf eine zentrale Lagerung (Träger), anhand der Merkmale vom Patentanspruch 1. Demnach sind die Achsen der beiden Doppelzahnräder einerseits im Gehäusedeckel und andererseits im Gehäuse in Lagerkavitäten lösbar eingesteckt aufgenommen. Ein gesondert eingefügtes Trägerelement ist eliminiert, indem dessen Lagerfunktion unmittelbar von den flankierenden Gehäusebauteilen übernommen wird.According to the invention the object is achieved by means of a special actuator as well as by means of a special assembly process in dissolved construction / assembly. All this is done under special compression, with no central storage (carrier), based on the features of claim 1. Accordingly, the axes of the two double gears on the one hand in the housing cover and on the other hand in the housing in bearing cavities releasably inserted added. A separately inserted carrier element is eliminated by its bearing function is taken directly from the flanking housing components.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Drehachse vom motorseitigen Doppelzahnrad als gesonderte Steckachse ausgebildet ist, und wobei die Steckachse ein Tragteil von dem Planetengetriebe außermittig durchgreift. Planetengetriebe und Doppelzahnrad sind dadurch in Ihrem Achsabstand zueinander besonders exakt ausgerichtet sowie gemeinsam im Gehäuse fixiert aufgenommen.In a further embodiment of the invention, it is provided that the axis of rotation is formed by the motor-side double gear as a separate plug-in axis, and wherein the plug-in axis passes through a support member of the planetary gear eccentrically. As a result, the planetary gear and the double gear are aligned particularly precisely with each other in their axial distance and are held together fixed in the housing.
Eine vorteilhafte Ausprägung definiert, dass das Tragteil über eine drehfeste Innenverzahnung verfügt, die zur Kooperation mit einem rotierenden Planetensatz vorgesehen ist.An advantageous embodiment defines that the support member has a rotationally fixed internal toothing, which is provided for cooperation with a rotating planetary gear set.
Eine weitere hochstabile Abwandlung der Erfindung sieht vor, dass das Planetengetriebe über das Tragteil, einschließlich formschlüssiger Aufnahme und Verdrehsicherungsmittel, mittelbar in einer Kavität vom Gehäuse am Gehäuseboden drehfest aufgenommen ist.Another highly stable modification of the invention provides that the planetary gear via the support member, including positive locking and anti-rotation, indirectly in a cavity of the housing on the housing bottom is rotatably received.
Eine fertigungstechnisch weiterentwickelte Besonderheit der Erfindung besteht darin, dass das abtriebsseitige Doppelzahnrad über einstückig angeformte Achsvorsprünge verfügt. Dies beinhaltet den Vorteil der vereinfachten Unterscheidbarkeit, weil die beiden verbauten Doppelzahnräder dadurch verschieden konstruiert sind. Dies ermöglicht zudem eine automatisierte Sortierung anhand optischer Bildverarbeitungsverfahren (Vertauschungsschutz) .A manufacturing technology further developed special feature of the invention is that the output side double gear has integrally molded axle protrusions. This has the advantage of simplified distinctness, because the two installed double gears are constructed differently. This also enables automated sorting using optical image processing methods (swapping protection).
Ein fertigungsgerechter Montageprozess vom Stellantrieb beinhaltet, dass die Getriebekomponenten zeitlich nacheinander, ausgehend von einer ersten Bezugsseite vom Gehäuse, gerichtet wie folgt im oder am Gehäuse montiert werden: a) Träger mit Planetengetriebe einschließlich Steckachse, b) abtriebsseitiges Doppelzahnrad, c) motorseitiges Doppelzahnrad, d) Getriebegehäusedeckel.A production-oriented assembly process by the actuator involves the transmission components being mounted in succession, starting from a first reference side of the housing, in or on the housing as follows: a) carrier with planetary gear including thru-axle, b) output side double gear, c) dual-side gear, d ) Gearbox housing cover.
Weiterhin kann a) der Motor und b) ein Gehäusedeckel, ausgehend von einer anders gelagerten, zweiten Bezugsseite gerichtet, zeitlich gestaffelt nacheinander wie auch zeitlich parallel im oder am Gehäuse montiert werden. Es ist in Weiterbildung vorgesehen, dass sich die beiden Bezugsseiten bzw. Kavitäten vom Gehäuse zueinander diametral versetzt am Gehäuse befinden.Furthermore, a) the motor and b) a housing cover, starting from a differently supported, second reference side directed, staggered successively as well as temporally parallel in or mounted on the housing. It is provided in a development that the two reference sides or cavities of the housing are diametrically offset from each other on the housing.
Soweit das Gehäuse zur Bestückung von unterschiedlich ausgerichteten Bezugsseiten auf einem Werkstückträger verschwenkbar fixiert eingespannt ist, ermöglicht dies den Prozessschritt, dass das Gehäuse zum Wechsel seiner Bestückung in seinem Arbeitsraum wenigstens einmal um 90° und/oder um 180° verschwenkt wird.As far as the housing is clamped fixed for mounting differently oriented reference sides on a workpiece carrier pivotally, this allows the process step that the housing is swiveled to change its placement in its working space at least once by 90 ° and / or 180 °.
