Description

Drehantrieb, insbesondere für Fahrzeugtüren Rotary drive, in particular for vehicle doors
Die Erfindung bezieht sich auf einen Drehantrieb, insbesondere für Fahrzeugtüren, bei dem die Kolbenbewegung einer hydraulischen oder pneumatischen KolbenArbeitszylinder-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 Abtriebs- welle verbunden ist, umgesetzt wird, wobei die Schlitze an ihren Enden in eine axiale Richtung übergehen. Die bekannten Drehantriebe dieser Art weisen denThe 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, the is connected to the output shaft, is implemented, the slots at their ends merging in an axial direction. The known rotary drives of this type have the
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 disadvantage is 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. Die Erfindung bezieht sich ferner auf bauliche Ausgestaltungen des Drehantriebes.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 tightly seated 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. 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, die Fig. 2 und 3 unterschiedliche Anordnungen eines Schalters und Fig. 4 einen Schnitt nach der Linie IV-IV 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, FIGS. 2 and 3 different arrangements of a switch, and FIG. 4 shows a section along the line IV-IV in FIG. 1.
Ein aus den Teilen 1a und 1b bestehendes topfförmiges Gehäuse 1, Fig. 4, 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. 4, 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. In the interior of the cylinder 4, a further cylinder 6 is provided coaxially, which 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. 2 und 3 zeigen. 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 äußerenBoth 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. 2 and 3. 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 with respect to the outer
Zylinder 4 verdreht und auf diese Weise die Türbewegung bewirkt.Cylinder 4 rotates and in this way causes the door to move.
Dieser Aufbau des Drehantriebes ist bekannt und daher nicht Gegenstand der Erfindung. Zum dichten Abschluß dieses Antriebes ist derThis structure of the rotary drive is known and is therefore not the subject of the invention. For the tight closure of this drive is the
Deckel 2 mit einem die Abtriebswelle 7 umgehenden Kra gen 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. Auf diese Weise ist, wie Versuche gezeigt haben, eine völlige Abdichtung auch im rauhen Betrieb gewährleistet. 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. 4 zeigt.Cover 2 with a Kra bypassing the output shaft 7 gene 15 provided, from which the outer end face is inclined towards the lid edge, so that liquids are drained 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 tightly against 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. In this way, as tests have shown, a complete seal is guaranteed even in rough operation. 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. 4.
Es ist vielfach erwünscht, daß der Zustand des Drehantriebes signalisiert wird, vor allem soll der Verriegelungszustand angezeigt werden. Zu diesem Zweck war es bisher üblich, einen entsprechenden Schalter vorzusehen, der von der Lage der Achse 13 für die Rollenpaare 14 in Umfangsrichtung beeinflußt wurde. Da sich jedoch die Richtung der Schlitze 10 und 11 in ihrem Endbereich der axialen Richtung nähern, ist die Abtastgenauigkeit gering. Zur Beseitigung dieses Übelstandes ist erfindungsgemäß vorgesehen, die axiale Lage der Achse 13 abzutasten. Da die Bewegung dieser Achse 13 in den Endabschnitten der Schlitze 10 und 11 in axialer Richtung die in Umfangsrichtung bei weitem übersteigt, kann dadurch die Genauigkeit der Abtastung wesentlich erhöht werden. Wie aus Fig. 2 ersichtlich, ist an einem Arm 21 ein Schalter 22 vorgesehen, dessen Schaltarm 23 eine Tastrolle 24 trägt, die mit einer Scheibe 25, die auf der Achse 13 sitzt, zusammenwirkt. Bei der in Fig.2 dargestellten Lage des Schalters 22 wird die Endlage des Dreh- antriebes abgetastet und damit das Signal "Tür verriegelt" gegeben. Gemäß Fig. 3 ist der Schalter 22 am Arm 21 versetzt angeordnet und dieser Arm schräg angebracht, so daß die Tastrolle 24 die Scheibe 25 in einem Bewegungsabschnitt der Achse 13 überwacht, der vom Übergang der Schlitze 10, 11 in die axiale Richtung gebildet ist. Bei dieser Anordnung signalisiert der Schalter 22 "Reversierung abgeschaltet".It is often desirable that the status of the rotary actuator is signaled, above all the locking status should be displayed. For this purpose, it has previously been customary to provide a corresponding switch which was influenced in the circumferential direction by the position of the axis 13 for the roller pairs 14. However, since the direction of the slits 10 and 11 approaches the axial direction in their end portion, the scanning accuracy is poor. To eliminate this problem, the invention provides for the axial position of the axis 13 to be scanned. Since the movement of this axis 13 in the end sections of the slots 10 and 11 in the axial direction far exceeds that in the circumferential direction, the accuracy of the scanning can be significantly increased. As can be seen from FIG. 2, a switch 22 is provided on an arm 21, the switching arm 23 of which carries a sensing roller 24 which interacts with a disk 25 which is seated on the axis 13. In the position of the switch 22 shown in FIG. 2, the end position of the rotary drive is scanned and the signal "door locked" is given. 3, the switch 22 is offset on the arm 21 and this arm is mounted obliquely, so that the feeler roller 24 monitors the disc 25 in a movement section of the axis 13, which is formed by the transition of the slots 10, 11 in the axial direction. In this arrangement, the switch 22 signals "reversing switched off".
Es ist somit erfindungsgemäß ein Schalter vorgesehen, dessen Taster in einem Abschnitt der Bewegungsbahn eines aus dem äußeren, mit den schrägen Schlitzen versehenen Zylinder nach außen vorstehenden Teil des die Rollenpaare tragenden Achse ragt, wobei sich der Abschnitt am Ende der Bewegungsbahn oder am Übergang in den axialen Bereich der schrägen Schlitze befindet. Die Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt. According to the invention, a switch is thus provided, the button of which protrudes in a section of the movement path of a part of the axis bearing the roller pairs that projects outwards from the outer cylinder provided with the oblique slots, the section being located at the end of the movement path or at the transition into the axial area of the oblique slots is located. The invention is not limited to the illustrated embodiment.
