Description
Stand der TechnikState of the art
Die Erfindung betrifft eine Antriebseinrichtung für einen Komfortantrieb eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen Komfortantrieb mit einer erfindungsgemäßen Antriebseinrichtung.The invention relates to a drive device for a comfort drive of a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a comfort drive with a drive device according to the invention.
Eine Antriebseinrichtung nach dem Oberbegriff des Anspruchs 1 ist aus der nachveröffentlichten
Aus der
Offenbarung der ErfindungDisclosure of the invention
Die Antriebseinrichtung für einen Komfortantrieb eines Kraftfahrzeugs mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass ein Ausgleich von Bauteiltoleranzen zwischen Schneckenrad, Innengehäuse und Außengehäuse der Antriebseinrichtung bei gleichzeitig optimierten Betriebseigenschaften, insbesondere im Sinne einer Geräuscharmut erzielt wird. The drive device for a comfort drive of a motor vehicle with the features of claim 1 has the advantage that a compensation of component tolerances between the worm wheel, inner casing and outer casing of the drive device is achieved with simultaneously optimized operating characteristics, in particular in the sense of low noise.
Der Erfindung liegt die Idee zugrunde, das Schneckenrad innerhalb des Innengehäuses mit Axialspiel anzuordnen (wobei sich das Axialspiel auf das Spiel in Richtung der Längsachse des Übertragungselements bzw. des Schneckenrads bezieht) und durch eine Kraft auf das Schneckenrad das Schneckenrad in Richtung seiner Längsachse so zu beaufschlagen, so dass das Schneckenrad stets an einer Fläche des Innengehäuses anliegt. The invention is based on the idea to arrange the worm within the inner housing with axial play (the axial play refers to the game in the direction of the longitudinal axis of the transmission element or the worm wheel) and by a force on the worm wheel, the worm wheel in the direction of its longitudinal axis so apply pressure so that the worm wheel always rests against a surface of the inner housing.
Vorteilhafte Weiterbildungen der erfindungsgemäßen Antriebseinrichtung für einen Komfortantrieb eines Kraftfahrzeugs sind in den Unteransprüchen aufgeführt. Advantageous developments of the drive device according to the invention for a comfort drive of a motor vehicle are listed in the subclaims.
Besonders einfach, preisgünstig und raumsparend lässt sich eine derartige Kraftbeaufschlagung des Übertragungselements bzw. Schneckenrads durch ein Federelement in Form eines Wellrings erzeugen. Die Anordnung des Federelements zwischen dem Schneckenrad und dem Innengehäuse erfolgt in Abhängigkeit von der Drehrichtung des Antriebs. Bei einem reversierbaren bzw. drehrichtungsumkehrbaren Antrieb ist es daher ggf. sinnvoll bzw. erforderlich, beidseitig des Schneckenrads jeweils ein Federelement vorzusehen. Such a force application of the transmission element or worm wheel by a spring element in the form of a corrugated ring can be particularly simple, inexpensive and space-saving. The arrangement of the spring element between the worm wheel and the inner housing takes place in dependence on the direction of rotation of the drive. In the case of a reversible or rotationally reversible drive, it may therefore be useful or necessary to provide a spring element on both sides of the worm wheel.
In konstruktiv bevorzugter Ausgestaltung, die es ermöglicht, bei der Montage des Schneckenrads und des Federelements in dem Innengehäuse die gewünschte Kraftbeaufschlagung zu erzeugen, wird vorgeschlagen, dass das Innengehäuse aus wenigstens zwei Gehäuseelementen besteht, die eine senkrecht zur Längsachse des Übertragungselements bzw. des Schneckenrads angeordnete Trennungsebene aufweisen, dass in wenigstens einem der Gehäuseelemente die Aufnahme für das Schneckenrad ausgebildet ist, und dass die Aufnahme für das Schneckenrad in Richtung der Längsachse des Übertragungselements bzw. des Schneckenrads eine Ausdehnung aufweist, die bei miteinander verbundenen Gehäuseelementen eine Vorspannung auf das Federelement erzeugt. Mit anderen Worten gesagt bedeutet dies, dass das Innengehäuse im Bereich des Schneckenrads eine derartige Dimensionierung aufweist, dass ein Axialspalt vorhanden ist, dessen axiale Erstreckung geringer ist als die des Federelements im unbelasteten Zustand, so dass im Einbauzustand des Schneckenrads in dem Innengehäuse das Federelement innerhalb des angesprochenen Axialspalts unter elastischer Vorspannung angeordnet ist und das Schneckenrad in Richtung des Innengehäuses kraftbeaufschlagt. In a structurally preferred embodiment, which makes it possible to produce the desired application of force when mounting the worm wheel and the spring element in the inner housing, it is proposed that the inner housing consists of at least two housing elements which are arranged perpendicular to the longitudinal axis of the transmission element or worm wheel Have separation plane, that in at least one of the housing elements, the receptacle for the worm wheel is formed, and that the receptacle for the worm wheel in the direction of the longitudinal axis of the transmission element or the worm wheel has an extension which generates a bias on the spring element in interconnected housing elements. In other words, this means that the inner housing in the region of the worm wheel has a dimensioning such that an axial gap is present, the axial extent is less than that of the spring element in the unloaded state, so that in the installed state of the worm wheel in the inner housing, the spring element is disposed within the aforementioned axial gap under elastic bias and the force applied to the worm wheel in the direction of the inner housing.
Zur Vereinfachung der Montage der Gehäuseelemente kann es vorgesehen sein, dass die wenigstens zwei Gehäuseelemente während eines Vormontageschritts durch eine Rastverbindung miteinander verbunden sind. Insbesondere sind bei einer derartigen Gehäusekonstruktion auch keine separaten Befestigungselemente wie Schrauben erforderlich.To simplify the mounting of the housing elements, it can be provided that the at least two housing elements are connected to each other during a Vormontageschritts by a latching connection. In particular, no separate fasteners such as screws are required in such a housing construction.
Weiterhin ist es zur Minimierung der Reibung, insbesondere mit Blick auf die Kraftbeaufschlagung des Schneckenrads in dem Innengehäuse, vorgesehen, dass das Übertragungselement (Schneckenrad) in Richtung der Längsachse des Übertragungselements bzw. des Schneckenrads unter Zwischenlage wenigstens eines axialen Lagerelements in dem Innengehäuse gelagert ist.Furthermore, in order to minimize the friction, in particular with regard to the application of force to the worm wheel in the inner housing, it is provided that the transmission element (worm wheel) is mounted in the inner housing in the direction of the longitudinal axis of the transmission element or the worm wheel with the interposition of at least one axial bearing element.
Eine Optimierung der Lagerung bzw. Wirkungsgraderhöhung lässt sich bei einem reversierbaren Antrieb erzielen, wenn beidseitig des Übertragungselements jeweils ein axiales Lagerelement vorgesehen ist.An optimization of the storage or increase in efficiency can be achieved in a reversible drive, if on both sides of the transmission element in each case an axial bearing element is provided.
Eine konstruktiv besonders einfache und genaue radiale Lagerung des Schneckenrads wird erzielt, wenn das Schneckenrad beidseitig eines mit dem Abtriebselement zusammenwirkenden Verzahnungsbereichs jeweils einen hülsenförmigen Lagerfortsatz aufweist, der in jeweils einer Ausnehmung des Innengehäuses radial gelagert aufgenommen ist. A structurally particularly simple and accurate radial bearing of the worm wheel is achieved when the worm wheel on both sides of a cooperating with the output element toothing region each having a sleeve-shaped bearing extension, which is received radially in each case a recess of the inner housing.
Zuletzt umfasst die Erfindung auch einen Komfortantrieb mit einer soweit beschriebenen erfindungsgemäßen Antriebseinrichtung. Der Komfortantrieb weist die im Rahmen der Beschreibung der Antriebseinrichtung erwähnten Vorteile auf. Ein derartiger Komfortantrieb kann insbesondere, und nicht einschränkend, in Form eines Sitzverstellungsantriebs oder eines Lenksäulenantriebs ausgebildet sein. Finally, the invention also includes a comfort drive with a drive device according to the invention described so far. The comfort drive has the advantages mentioned in the description of the drive device. Such a comfort drive can be designed in particular, and not restrictively, in the form of a seat adjustment drive or a steering column drive.
