Abstract

In a rotary drive, particularly for vehicle doors, the piston stroke of a piston-cylinder unit (5) is converted into a rotary motion by pairs of cylinders (14) which engage inclined slots (10, 11). The inclined slots are formed in cylinders (4, 6) coaxially arranged into each other, one of the cylinders being connected to the output shaft (7). The slots are axially orientated at their ends. The cover (2) of a pot-shaped housing (1) traversed by the output shaft (7) is provided with a collar (15) which projects outwardly and which surrounds the output shaft. The output shaft (7) is surrounded by a seal (17) of which the envelope (18) covers the outer side of the collar (15) and of which the edge (19) sealingly bears against the cover (2). The cover is provided on its side opposite to the collar with an axial groove (20) wherein the edge of the pot-shaped housing (1) is sealingly engaged.

Description

Die Erfindung bezieht sich auf einen Drehantrieb, insbesondere für Fahrzeugtüren, bei dem die Kolbenbewegung einer hydraulischen oder pneumatischen Kolben-Arbeitszylinder-Einheit mittels Rollenpaaren, die in geneigte Schlitze, welche in koaxial ineinander angeordneten Zylindern vorgesehen sind, eingreifen, in eine Drehbewegung eines dieser Zylinder, der mit der Abtriebswelle verbunden ist, umgesetzt wird, wobei die Schlitze an ihren Enden in eine axiale Richtung übergehen.The invention relates to a rotary drive, in particular for vehicle doors, in which the piston movement of a hydraulic or pneumatic piston-working cylinder unit by means of pairs of rollers which engage in inclined slots, which are provided in cylinders arranged coaxially one inside the other, in a rotary movement of one of these cylinders , which is connected to the output shaft, is implemented, the slots merging at their ends in an axial direction.

Die bekannten Drehantriebe dieser Art (siehe z. B. AT-B-342 478) weisen den Nachteil auf, daß sie oft den schweren Bedingungen, denen sie ausgesetzt sind, nicht entsprechen. Vor allem zeigen sich immer wieder Undichtheiten im Gehäuse, vor allem im Bereich des Durchtrittes der Abtriebswelle, so daß es zu Funktionsmängeln kommt.The known rotary drives of this type (see, for example, AT-B-342 478) have the disadvantage that they often do not meet the severe conditions to which they are exposed. Above all, there are always leaks in the housing, especially in the area of the passage of the output shaft, so that there are functional deficiencies.

Die Erfindung bezweckt die Schaffung eines Drehantriebes mit dichtem Gehäuse, das jedoch die Zugänglichkeit der Bauteile des Antriebes nicht erschwert.The invention aims to create a rotary drive with a sealed housing, but which does not make the components of the drive difficult to access.

Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß der von der Abtriebswelle durchsetzte Deckel des topfförmigen Gehäuses einen nach außen ragenden, die Abtriebswelle umgebenden Kragen aufweist und die Abtriebswelle mit einer in einer Ringnut dicht sitzenden Topfdichtung versehen ist, deren Mantel den Kragen außen übergreift und mit seinem Rand dicht am Deckel anliegt, wobei dieser an seiner vom Kragen abgewendeten Seite mit einer axial gerichteten Ringnut versehen ist, in die der Rand des topfförmigen Gehäuses dicht eingesetzt ist.According to the invention, this aim is achieved in that the cover of the pot-shaped housing penetrated by the output shaft has an outwardly projecting collar surrounding the output shaft and the output shaft is provided with a cup seal which sits tightly in an annular groove, the jacket of which overlaps the collar on the outside and with it Edge lies tightly against the cover, which is provided on its side facing away from the collar with an axially directed annular groove into which the edge of the pot-shaped housing is inserted tightly.

Die Erfindung bezieht sich ferner auf bauliche Ausgestaltungen des Drehantriebes.The invention further relates to structural designs of the rotary drive.

In der Zeichnung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführungsform dargestellt. Es zeigen Fig. 1 einen Axialschnitt durch den Drehantrieb und Fig. 2 einen Schnitt nach der Linie 11-11 in Fig.1.In the drawing, the subject matter of the invention is shown in an exemplary embodiment. 1 shows an axial section through the rotary drive and FIG. 2 shows a section along the line 11-11 in FIG. 1.

Ein aus den Teilen 1a und 1b bestehendes topfförmiges Gehäuse 1, Fig. 2, ist mit einem Deckel 2 verschlossen, der einen Befestigungsflansch 3 für den Drehantrieb aufweist. Im Inneren des Gehäuses ist ein äußerer Zylinder 4 vorgesehen, der fest mit dem Deckel 2 und mit einem in seiner Gesamtheit mit 5 bezeichneten Kolbenzylindereinheit fest verbunden ist. Diese Einheit kann für hydraulische oder pneumatische Medien eingerichtet sein. Im Inneren des Zylinders 4 ist koaxial ein weiterer Zylinder 6 vorgesehen, der in eine den Deckel 2 durchsetzenden Abtriebswelle 7 übergeht. Der innere Zylinder ist mittels der Kugellager 8, 9 drehbar gelagert.A pot-shaped housing 1, FIG. 2, consisting of parts 1a and 1b, is closed with a cover 2, which has a fastening flange 3 for the rotary drive. In the interior of the housing, an outer cylinder 4 is provided, which is firmly connected to the cover 2 and to a piston-cylinder unit, designated in its entirety by 5. This unit can be set up for hydraulic or pneumatic media. A further cylinder 6 is provided coaxially inside the cylinder 4 and merges into an output shaft 7 passing through the cover 2. The inner cylinder is rotatably supported by means of the ball bearings 8, 9.

Beide Zylinder weisen Schlitze 10 und 11 auf, die schräg zur Achse des Antriebes verlaufen und an ihren Enden in eine axiale Richtung übergehen, wie dies die Fig. und 3 zeigen.Both cylinders have slots 10 and 11, which run obliquely to the axis of the drive and at their ends merge into an axial direction, as shown in FIGS. 3 and 3.

Auf der Kolbenstange 12 der Kolbenzylindereinheit 5 sitzt eine radial gerichtete Achse 13, auf der beiderseits Rollenpaare 14 drehbar gelagert sind. Die Rollen laufen in den Schlitzen 10 und 11. Bei einer Axialbewegung der Kolbenstange 12 wird der innere Zylinder 6 und somit die Abtriebswelle 7 gegenüber dem äußeren Zylinder 4 verdreht und auf diese Weise die Türbewegung bewirkt.On the piston rod 12 of the piston-cylinder unit 5 there is a radially directed axis 13 on which pairs of rollers 14 are rotatably mounted on both sides. The rollers run in the slots 10 and 11. With an axial movement of the piston rod 12, the inner cylinder 6 and thus the output shaft 7 are rotated relative to the outer cylinder 4 and in this way the door movement is effected.

Dieser Aufbau des Drehantriebes ist bekannt und daher nicht Gegenstand der Erfindung.This structure of the rotary drive is known and is therefore not the subject of the invention.

Zum dichten Abschluß dieses Antriebes ist der Deckel 2 mit einem die Abtriebswelle 7 umgebenden Kragen 15 versehen, von dem zum Deckelrand hin die äußere Stirnfläche geneigt verläuft, so daß Flüssigkeiten zum Umfang abgeleitet werden. Die Abtriebswelle 7 ist mit einer Ringnut 16 versehen, in der eine Topfdichtung 17 dicht eingesetzt ist. Der Mantel 18 dieser Dichtung umgreift den Kragen 15 und der Dichtungsrand 19 liegt dicht an der Stirnfläche des Deckels 2 an. Dieser weist an der entgegengesetzten Seite eine axial gerichtete Ringnut 20 auf, in die der Rand des Gehäuses 1 dicht eingesetzt ist.To seal this drive tightly, the cover 2 is provided with a collar 15 surrounding the output shaft 7, from which the outer end face extends inclined toward the cover edge, so that liquids are drained off to the periphery. The output shaft 7 is provided with an annular groove 16 in which a cup seal 17 is inserted tightly. The jacket 18 of this seal engages around the collar 15 and the sealing edge 19 lies close to the end face of the cover 2. This has an axially directed annular groove 20 on the opposite side, in which the edge of the housing 1 is inserted tightly.

Auf diese Weise ist, wie Versuche gezeigt haben, eine völlige Abdichtung auch im rauhen Betrieb gewährleistet.In this way, as tests have shown, a complete seal is guaranteed even in rough operation.

Um die Zugänglichkeit der einzelnen Bauteile zu erleichtern, ist das Gehäuse 1 vorzugsweise nach einer Ebene, die parallel zur Kolbenstange 12 verläuft, geteilt, wie dies Fig. 2 zeigt.In order to facilitate the accessibility of the individual components, the housing 1 is preferably divided according to a plane that runs parallel to the piston rod 12, as shown in FIG. 2.

Die Erfindung wie in den Patentansprüchen definiert ist nicht auf die dargestellte Ausführungsform beschränkt.The invention as defined in the claims is not limited to the illustrated embodiment.
