Description

Technisches GebietTechnical field

Die Erfindung bezieht sich auf eine Antriebsvorrichtung für eine Fahrzeugtür, die als Innen-oder Aussenschwenktür oder Falttür an einer mit Antriebskurbel versehenen Drehsäule aufgehängt ist, wobei das Betätigungsmoment durch ein Notauslösesystem reduzierbar ist.The invention relates to a drive device for a vehicle door, which is suspended as an inner or outer swing door or folding door on a rotating column provided with a drive crank, the actuating torque being able to be reduced by an emergency release system.

Stand der TechnikState of the art

Es ist bekannt, im Dachbereich über der Tür einen schwenkbar gelagerten, beidseitig beaufschlagbaren Druckluftzylinder anzuordnen, dessen Kolbenstange an der mit der Drehsäule fest verbundenen Kurbelstange angreift. Da die Türen meist als Doppeltüren ausgebildet sind, benötigt man pro Türsystem zwei neben- oder hintereinander liegende Druckluftzylinder. Um die Türen im geschlossenen Zustand zu arretieren, werden zusätzliche mittel benötigt. Es ist aber auch bekannt, die Druckluft anstehen zu lassen, um die Türblätter gegen Fahrtwinddruck und Erschütterungen in Schliessslage zu halten. Aus Sicherheitsgründen weisen die Türen ein Notöffnungssystem auf. Vorwiegend wird hierfür ein sogenannter Nothahn eingesetzt, dessen Betätigung den Luftdruck abbaut, so dass die Tür bei drucklosem Zylinder von Hand betätigt werden kann. Der Fahrgast muss also im Notfall die Kolbenreibung im Zylinder überwinden und die eingeschlossene Luft verdrängen, was zusätzliche Kraft kostet.It is known to arrange in the roof area above the door a pivotably mounted compressed air cylinder which can be acted upon from both sides, the piston rod of which engages the crank rod which is firmly connected to the rotating column. Since the doors are usually designed as double doors, two compressed air cylinders are required for each door system. Additional means are required to lock the doors when closed. However, it is also known to let the compressed air stand in order to keep the door leaves in the closed position against wind pressure and vibrations. For security reasons, the doors have an emergency opening system. A so-called emergency valve is mainly used for this purpose, the actuation of which reduces the air pressure so that the door can be actuated by hand when the cylinder is depressurized. In an emergency, the passenger must overcome the piston friction in the cylinder and displace the trapped air, which costs additional power.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen besonders einfachen und zuverlässigen elektromotorischen Antrieb zu schaffen, der wahlweise ein- oder zweiflügelige Türen synchron betätigen kann, der türseitig keine besonderen Verriegelungselemente benötigt und der mit einer Notauslöseeinrichtung ausgerüstet ist.The invention has for its object to provide a particularly simple and reliable electromotive drive that can optionally operate single or double-leaf doors synchronously, that does not require any special locking elements on the door side and that is equipped with an emergency release device.

Besonderer Wert wird darauf gelegt, dass die Notöffnung der Tür keine besondere Kraftanstrengung erfordert.It is particularly important that the emergency opening of the door does not require any special effort.

Diese Aufgabe wird dadurch gelöst, dass auf einer im Türdrehbereich befestigten Basisplatte eine mit Zahnkranz vesehene Antriebsscheibe mittels vertikaler Drehachse gelagert ist, dass diese Antriebsscheibe an der Unterseite mindestens einen exzentrischen Zapfen aufweist, der über eine Schubstange mit der Antriebskurbel verbunden ist, dass über der Antriebsscheibe ein Elektromotor mit Getriebe angeordnet ist, dass Motor und Getriebe auf einer Schwinge gelagert sind und dass diese Schwinge von einer mit dem Notauslösesystem verbundenen Kulisse gesteuert ist, die den zur Entkupplung erforderlichen Achsabstand zwischen Antriebsscheibe und dem schwimmend gelagerten Abtriebsrad bewirkt.This object is achieved in that a drive disk provided with a toothed ring is mounted on a base plate fastened in the door rotating area by means of a vertical axis of rotation, that this drive disk has at least one eccentric pin on the underside, which is connected to the drive crank via a push rod, that above the drive disk an electric motor with a gearbox is arranged, the motor and gearbox are mounted on a rocker arm and that this rocker arm is controlled by a link connected to the emergency release system, which causes the center distance between the drive pulley and the floating driven gear wheel, which is required for uncoupling.

Bei einem bevorzugten Ausführungsbeispiel wird die waagerecht liegende Antriebsscheibe so angeordnet, dass der Abtriebszapfen bei geschlossenem Türflügel eine Totlage einnimmt, die mit Hilfe eines Notauslösehebels überwindbar ist. Ganz besonders vorteilhaft ist es, mit dem Notauslösehebel zunächst den Antrieb zu entkuppeln und dann zwangsläufig die Antriebsscheibe aus der Totlage herauszuführen.In a preferred embodiment, the horizontally lying drive disk is arranged such that the driven pin assumes a dead position when the door leaf is closed, which can be overcome with the aid of an emergency release lever. It is particularly advantageous to first decouple the drive with the emergency release lever and then inevitably lead the drive disk out of the dead position.

In Fig. 1 ist mit 1 eine Basisplatte bezeichnet, die z.B. im Dachbereich des Fahrzeuges über der Mittellinie einer zweiflügeligen Innenschwenktür befestigt sein kann. Auf dieser Platte ist mittels vertikaler Achse 8 eine Antriebsscheibe 2 einseitig gelagert. Der äussere Rand dieser Scheibe trägt eine Verzahnung und steht im Eingriff mit einem Abtriebsrad 3 eines strichpunktiert angedeuteten Getriebemotors 4. Die Rotorwelle des Motors 4, deren Achse 5a mit strichpunktierten Linien angedeutet ist, treibt über ein Schneckengetriebe das Abtriebsrad 3 an. Die Antriebsscheibe 2 ist über einen Zapfen 8 auf der Basisplatte 1 drehbar gelagert. Sie trägt an ihrer Unterseite zwei exzentrische Zapfen 10, 11, auf denen abgekröpfte Schubstangen 12, 13 gelagert sind. Die mit ausgezogenen Linien dargestellte Lage der Schubstangen 12, 13 stellt eine Totpunktlage oder besser leicht überzogene Totpunktlage dar, die der Schliessstellung der Türflügel entspricht. Durch Drehung der Antriebsscheibe 2 entgegen dem Uhrzeigersinn wird die Öffnung der Türflügel eingeleitet. Die Kröpfung der Schubstangen ist erforderlich, damit jeweils die Schubstange des einen Türflügels in der Totpunktlage um den Zapfen des anderen Türflügels und um den Zapfen 8 herumgreifen kann. Die Ausnutzung der Kurbeltotpunkte hat den grossen Vorteil, dass man mit kleiner Antriebskraft an der Antriebsscheibe 2 grosse Schliesskräfte an den Türdichtungen erzielt und dass sich die Türflügel durch leichte Überschreitung des Totpunktes in der Schliessstellung selbst halten.In Fig. 1, 1 denotes a base plate which e.g. can be attached in the roof area of the vehicle above the center line of a double-leaf inner swing door. A drive disc 2 is supported on one side on this plate by means of a vertical axis 8. The outer edge of this disk has a toothing and is in engagement with an output gear 3 of a geared motor 4 indicated by dash-dotted lines. The rotor shaft of motor 4, the axis 5a of which is indicated by dash-dotted lines, drives the output gear 3 via a worm gear. The drive pulley 2 is rotatably mounted on the base plate 1 via a pin 8. It carries on its underside two eccentric pins 10, 11 on which cranked push rods 12, 13 are mounted. The position of the push rods 12, 13 shown in solid lines represents a dead center position or, better, slightly dead center position, which corresponds to the closed position of the door leaves. By turning the drive pulley 2 counterclockwise, the opening of the door leaves is initiated. The cranking of the push rods is required so that in each case the push rod of one door leaf can reach around the pin of the other door leaf and around the pin 8 in the dead center position. Exploiting the dead center of the crank has the great advantage that 2 small closing forces are achieved on the door seals with a small driving force on the drive disk and that the door leaves keep themselves in the closed position by slightly exceeding the dead center.

Mit 14,15 sind einstellbare Verschraubungen in den Schubstangen bezeichnet, mit denen die Schliessstellungen der Türflügel fein einjustiert werden können. In der Schliessstellung stossen die Schubstangen 12, 13 gegen die Zapfen 11 und 10.14, 15 indicates adjustable screw connections in the push rods with which the closing positions of the door leaves can be finely adjusted. In the closed position, the push rods 12, 13 push against the pins 11 and 10.

Mit 31 ist eine Schwinge bezeichnet, die mittels einer Exzenterschraube 18 schwenkbar gelagert ist und die über das Getriebe den Motor 4 trägt. Durch Schwenkung entgegen dem Uhrzeigersinn wird das Abtriebsrad 3 von der Antriebsscheibe 2 entkuppelt. Diese Bewegung wird über den Stift 31a durch eine Kulisse 32 erzwungen, die über der Scheibe 2 auf der Achse 8 drehbar gelagert ist und deren Hebelarm 32a mit der Seele 19a eines Bowdenzuges 19 verbunden ist. Die Führung 19b des Bowdenzuges ist einstellbar mit einem Winkelblech 45 verschraubt, das zugleich die Endschalter 16, 17 trägt. Wenn über den Notauslösehebel (Fig. 6 und 7) der Bowdenzug betätigt wird, schiebt zunächst die Kulisse 32 über die Aussparung 32b den Stift 31 a nach rechts, bis die Verbindung zum Antrieb gelöst ist. In dieser Ablaufphase stösst die Kulisse 32 gegen den auf der Scheibe 2 sitzenden Anschlagstift 33, so dass diese Scheibe unter Überwindung des Totpunktes entgegen dem Uhrzeigersinn mitgenommen wird. Dadurch ist es dem Fahrgast sehr leicht möglich, nach dem Umlegen des Notauslösehebels die Tür von Hand voll aufzuschieben. Auf der Achse 8 ist zwischen Scheibe 2 und Kulisse 32 eine Schenkelfeder 9 angeordnet, die die Kulisse bei Entlastung des Bowdenzuges in die Ausgangslage zurückführt und dabei das Getriebe wieder einkuppelt.With 31 a rocker is designated, which is pivotally mounted by means of an eccentric screw 18 and which carries the motor 4 via the gear. By turning it counterclockwise the driven wheel 3 is uncoupled from the drive pulley 2. This movement is forced via the pin 31a by a link 32 which is rotatably mounted on the axis 8 above the disk 2 and whose lever arm 32a is connected to the core 19a of a Bowden cable 19. The guide 19b of the Bowden cable is screwed to an angle plate 45, which also carries the limit switches 16, 17. If the Bowden cable is actuated via the emergency release lever (FIGS. 6 and 7), the link 32 first pushes the pin 31a to the right via the cutout 32b until the connection to the drive is released. In this phase, the link 32 abuts the stop pin 33 seated on the disc 2, so that this disc is taken counterclockwise while overcoming the dead center. This makes it very easy for the passenger to push open the door fully by hand after flipping the emergency release lever. On the axis 8, a leg spring 9 is arranged between the disc 2 and the link 32, which returns the link to the starting position when the Bowden cable is relieved and thereby engages the transmission again.

Bei normaler Betätigung der Tür wird der umsteuerbare Motor 4 durch Steuerbefehl in Schliess- oder Öffnungsrichtung eingeschaltet und am Ende des Vorganges durch den jeweiligen Endschalter stillgesetzt. Zur Steuerung der Endschalter dienen verstellbare Nocken 41, 42, die in zirkumpolaren Nuten 43, 44 befestigt sind.When the door is operated normally, the reversible motor 4 is switched on by a control command in the closing or opening direction and stopped at the end of the process by the respective limit switch. Adjustable cams 41, 42, which are fastened in circumpolar grooves 43, 44, serve to control the limit switches.

In Fig.2 ist mit 1 wiederum die Basisplatte bezeichnet, die mit der Achse 8, der Schraube 18 und dem Winkelblech 45 verbunden ist. Auf der Aussenverzahnung der Antriebsscheibe 2 rollt das Abtriebsrad 3 des Schneckengetriebes 6, 7 ab, das mit dem Motor 4 eine Einheit bildet. Über der Antriebsscheibe 2 und dem Abtriebsrad 3 ist die Kulisse 32 und die Schwinge 31 zu erkennen. Der Motor 4 ist über das Gehäuse des Getriebes 6, 7 und angegossene Bolzen 46, 47 mit der Schwinge 31 fest verbunden. Er wird also beim Ein- und Auskuppeln über die Kulisse 32 und die Schwinge 31 mit verschwenkt. Zwischen der Abtriebswelle 21 des Getriebes 6, 7 und dem Abtriebsrad 3 ist eine Rutschkupplung 30 vorgesehen, die durch eine Schraubenfeder 22 zusammengepresst wird.In Figure 2, 1 again designates the base plate, which is connected to the axis 8, the screw 18 and the angle plate 45. The output gear 3 of the worm gear 6, 7, which forms a unit with the motor 4, rolls on the external toothing of the drive disk 2. The link 32 and the rocker 31 can be seen above the drive pulley 2 and the driven wheel 3. The motor 4 is fixedly connected to the rocker arm 31 via the housing of the transmission 6, 7 and cast bolts 46, 47. It is pivoted with the coupling 32 and the rocker 31 when coupling and uncoupling. A slip clutch 30 is provided between the output shaft 21 of the transmission 6, 7 and the output wheel 3 and is pressed together by a helical spring 22.

Aus Fig. ist die Dreh- bzw. Türsäule 24 des rechten Türflügels, die dazugehörige Kurbel 25 und die Schubstange 12 zu erkennen. Mit ausgezogenen Linien (25) ist die Schliessstellung gezeichnet, mit strichpunktierten (25') die Offenstellung. Der Betätigungswinkel beträgt beispielsweise 80°. Zwischen der Türsäule 24 und der Kurbel 25 ist eine Keilwellenverbindung 26 vorgesehen. Mit 27 ist das Türsäulenlager bezeichnet.The rotary or door pillar 24 of the right door wing, the associated crank 25 and the push rod 12 can be seen from FIG. The closed position is drawn with solid lines (25), the open position with dash-dotted lines (25 '). The actuation angle is 80 °, for example. A spline connection 26 is provided between the door pillar 24 and the crank 25. With 27 the door pillar bearing is designated.

Fig.4 zeigt die Anordnung nach Fig.3 im Schnitt. Auf dem Trägerblech 20 ist das Gehäuse des Türsäulenlagers 27 festgeschweisst. Die Kurbel 25 ist mit der drehbar gelagerten Buchse 28 verschweisst, die innen ein Keilwellenprofil aufweist. Das Gegenstück der Keilwellenverbindung sitzt auf einem Schaft 29, der in die Türsäule übergeht. Die dargestellte Keilwellenverbindung 26 überträgt grosse Drehmomente und erlaubt zugleich einen vertikalen Höhenausgleich sowie gewisse Abweichungen des Winkels zwischen dem Trägerblech 20 und derTürsäule 24.Figure 4 shows the arrangement of Figure 3 in section. The housing of the door pillar bearing 27 is welded onto the carrier plate 20. The crank 25 is welded to the rotatably mounted bushing 28, which has a splined profile on the inside. The counterpart of the spline connection sits on a shaft 29 which merges into the door pillar. The splined shaft connection 26 shown transmits high torques and at the same time permits vertical height compensation and certain deviations in the angle between the carrier plate 20 and the door pillar 24.

Fig. ist ein Schnitt entlang der Linie AB in Fig. 1. Motor, Getriebe, Schubstangen und Basisplatte sind zwischen einem strichpunktiert angedeuteten Trägerblech 20 und der ebenfalls strichpunktiert gezeichneten gekrümmten Dachkonstruktion 23 angeordnet. Hinter dem Winkelblech 45 sind die Oberteile der Endschalter 16, 17 zu erkennen.Fig. Is a section along the line AB in Fig. 1. Motor, transmission, push rods and base plate are arranged between a dash plate 20 indicated by dash-dotted lines and the curved roof structure 23 also shown in dash-dotted lines. The upper parts of the limit switches 16, 17 can be seen behind the angle plate 45.

Fig. 6 zeigt den Notauslösehebel 34, der um die Achse 35 drehbar ist und mit dem Exzenterhebel 36 eine Einheit bildet. Mit 37 ist ein Stift bezeichnet, der über eine Seilkausche 38 das Zugseil 19a des Bowdenzuges 19 trägt. Die genannten Teile sind auf beiden Seiten einer Griffplatte 39 angeordnet.Fig. 6 shows the emergency release lever 34 which is rotatable about the axis 35 and forms a unit with the eccentric lever 36. With 37 a pin is designated, which carries the pull rope 19a of the Bowden cable 19 via a rope thimble 38. The parts mentioned are arranged on both sides of a handle plate 39.

Fig. 7 stellt einen Schnitt entlang der Linie CD in Fig. 6 dar. Die Griffplatte 39 ist auf das Karosserieblech 40 aufgesetzt. Die Kulisse 32 bewirkt aufgrund ihrer Steuerkurve 32b, dass der erforderliche Achsabstand zwischen der Antriebsscheibe 2 und dem Abtriebsrad 3 des schwimmend gelagerten Motors eingeschaltet wird. Mit Hilfe der Kulisse werden die zwischen dem Abtriebsrad und der Antriebsscheibe anstehenden Kraftkomponenten abgefangen. Vorteilhaft ist dabei ferner, dass die Kulisse ohne grossen Kraftaufwand die Antriebsscheibe vom Abtriebsrad des Motors entkuppelt.FIG. 7 shows a section along the line CD in FIG. 6. The handle plate 39 is placed on the body panel 40. Due to its control curve 32b, the link 32 causes the required center distance between the drive pulley 2 and the driven wheel 3 of the floating motor to be switched on. The force components present between the driven gear and the drive pulley are intercepted with the aid of the backdrop. It is also advantageous that the link uncouples the drive pulley from the driven gear of the motor without great effort.

Bester Weg zur Ausführung der ErfindungBest way to carry out the invention

Die gesamte Antriebsvorrichtung wird beim Hersteller montiert und vorjustiert. Beim Einbau in das Fahrzeug ist dann nur noch eine Feinabstimmung erforderlich.The entire drive device is assembled and pre-adjusted by the manufacturer. When installing in the vehicle, only fine tuning is required.

Gewerbliche VerwertbarkeitCommercial usability

Die beschriebene Erfindung ist ganz besonders vorteilhaft bei zweiflügeligen Innenschwenktüren, weil man hierbei mit einem einzigen, preisgünstigen Antriebssystem auskommt. Sie ist aber auch für einflügelige Schwenk- oder Falttüren geeignet, wobei dann die Antriebsscheibe nur mit einer Schubstange ausgerüstet ist.The described invention is particularly advantageous in the case of double-leaf swing doors, because one single, inexpensive drive system is sufficient. But it is also suitable for single-leaf swing or folding doors, in which case the drive pulley is only equipped with a push rod.
