Description

Die Erfindung betrifft eine Stellvorrichtung für eine Kraftfahrzeugtür nach dem Hauptpatent ... (Patentanmeldung P 35 19 203.8-25).The invention relates to an actuating device for a motor vehicle door according to the main patent ... (patent application P 35 19 203.8-25).

Nach der Patentanmeldung P 35 19 203.8 wird eine Stellvorrichtung für eine Fahrzeugtür geschaffen, die ein augenblickliches Festsetzen der öffnenden Fahrzeugtür in jeder Zwischenstellung über die Betätigung eines Innen- oder Außengriffs ermöglicht. Diese Stellvorrichtung ist in der Weise ausgeführt, daß bei in Öffnungsrichtung betätigtem Griff die Tür leichtgängig zu öffnen ist. Dagegen ist bei in Schließrichtung betätigtem Griff die Tür über die Stellvorrichtung in jeder beliebigen Zwischenstellung festsetzbar. Ein Schließen der Tür erfolgt ohne Betätigung des Griffes leichtgängig, und hierbei ist kein Festsetzen in einer Zwischenstellung möglich.According to patent application P 35 19 203.8, an actuating device for a vehicle door is created, which enables the opening of the opening vehicle door to be locked in any intermediate position by actuating an inside or outside handle. This adjusting device is designed in such a way that the door can be opened easily when the handle is actuated in the opening direction. On the other hand, when the handle is actuated in the closing direction, the door can be fixed in any intermediate position via the adjusting device. The door closes smoothly without operating the handle, and it is not possible to lock it in an intermediate position.

Zur einfachen Bedienung der Tür im Bereich von kleinen Öffnungswinkeln beim anfänglichen Öffnen ist es Aufgabe der Erfindung, eine Stellvorrichtung zu schaffen, mit der unter Beibehaltung des Festsetzens der Tür gleichzeitig ein unbehindertes, leichtgängiges Öffnen möglich wird.For simple operation of the door in the range of small opening angles when opening the object, it is the object of the invention to provide an actuating device with which an unimpeded, smooth opening is simultaneously possible while maintaining the fixing of the door.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausbildungen der Erfindung beinhalten die Unteransprüche.This object is achieved by the characterizing features of claim 1. Further advantageous developments of the invention include the subclaims.

Nach dem Hauptpatent ... (Patentanmeldung P 35 19 203.8-25) kann die Tür über die Stellvorrichtung beim Öffnen in jeder beliebigen Zwischenstellung festgelegt werden und somit auch schon beim anfänglichen Öffnen mit klei­nem Öffnungswinkel. Damit nun die Tür unter Ausschaltung der Blockierung zu öffnen ist, ist ein Überströmkanal zwischen den beiden Arbeitskammern im Zylinder vorgesehen. In diesen Kanal taucht der Kolben der Einheit bei der Öffnung der Tür aus der Schließstellung heraus ein und ermöglicht einen unbehinderten Mediumaustausch zwischen den beiden Arbeitskammern. Erst nach Erreichen eines gewissen Öffnungswinkels der Tür wirkt die Blockierung über die Stellvorrichtung, d.h. der Türgriff muß wieder betätigt werden. Der Winkel zum blockierfreien Öffnen der Tür ohne Betätigung des Türinnengriffs soll ca. 30° betragen, so daß ein unbehindertes Aussteigen aus dem Fahrzeug für eine Durchschnittsperson möglich ist. Es hat sich herausgestellt, daß schon bei einem Türöffnungswinkel von ca. 20 ° die Bedingungen für eine Person zum Aussteigen optimal erfüllt sind.According to the main patent ... (patent application P 35 19 203.8-25), the door can be set in any intermediate position when opening, and thus even when it is initially opened with a small opening angle. So that the door can now be opened with the blocking switched off, an overflow channel is provided between the two working chambers in the cylinder. The piston of the unit dips into this channel when the door is opened from the closed position and enables an unimpeded medium exchange between the two working chambers. Only after When a certain opening angle of the door is reached, the blocking acts via the adjusting device, ie the door handle must be operated again. The angle for non-blocking opening of the door without actuating the inside door handle should be approximately 30 °, so that an average person can get out of the vehicle without hindrance. It has been found that even with a door opening angle of approximately 20 °, the conditions for one person to get out are optimally met.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.
Es zeigen

  • Fig. 1 eine Stellvorrichtung, bestehend aus einer Kolben-Zylinder-Einheit mit Überströmkanal, teilweise im Schnitt,
  • Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1,
  • Fig. 3 eine Stellvorrichtung bei geschlossener Tür mit im Überströmkanal eingetauchten Kolben, und
  • Fig. 4 die Stellvorrichtung bei ca. 30° geöffneter Tür mit den Überströmkanal abschließenden Kolben.
An embodiment of the invention is shown in the drawing and will be described in more detail below.
Show it
  • 1 is an actuating device consisting of a piston-cylinder unit with overflow channel, partly in section,
  • 2 shows a section along the line II-II of FIG. 1,
  • Fig. 3 is an actuator with the door closed with the plunger immersed in the overflow channel, and
  • Fig. 4, the actuator with about 30 ° open door with the overflow channel closing piston.

Die Vorrichtung 1 umfaßt im wesentlichen eine Kolben-Zylinder-Einheit 2, die einen Steuerkreis 3 aufweist, in dem ein Blockierventil 4 angeordnet ist. es kann innerhalb oder außerhalb der Einheit 2 vorgesehen werden. Sie ist zwischen einer Tür 5 und einer aufbauseitigen Konsole 6 um vertikale Achsen 7, 7a schwenkbar gehalten, wobei die Kolbenstange z.B. mit einem Scharnier 22 der Tür 5 verbunden ist. Bei einem Verschwenken der Tür 5 in Pfeilrichtung 8a (Öffnen) wird ein Kolben 9 der Einheit 2 in Pfeilrichtung 10 und bei einem Verschwenken in Pfeilrichtung 8 (Schließen) wird der Kolben 9 in Pfeilrichtung 11 bewegt. Dieser Kolben 9 weist Durchtritts­öffnung 12 für ein Druckmedium wie Gas, Hydrauliköl oder dergleichen auf. Die öffnungen 12 werden von einem durch eine Feder 14 geregelten inneren Ventil 13 in Abhängigkeit von der Türbewegung freigegeben oder geschlossen. Die den Steuerkreis 3 bildende Leitung der Vorrichtung 1 mündet mit ihrem Ein- und Auslaß in die vom Kolben 9 aufgeteilten Arbeitskammern 15 und 16 des Zylinders 25 ein. Das Blockierventil 4 ist entgegen der Strömungs­richtung 17 wirkend im Steuerkreis 3 angeordnet. Es ist über mechanische Stellmittel 18 in Abhängigkeit von einer Betätigung eines Türgriffs in eine Schließstellung (Pfeilrichtung 23) und in eine Freigabestellung (Pfeil­richtung 24) bewegbar. Das Blockierventil 4 ist über die mechanischen Stellmittel 18, welche durch Seil- oder Bowdenzug gebildet sein können, mit dem Türinnengriff und dem Türaußengriff verbunden. Über jeden Griff ist das Blockierventil 4 in die Freigabe- und Schließstellung zu verschieben.The device 1 essentially comprises a piston-cylinder unit 2 which has a control circuit 3 in which a blocking valve 4 is arranged. it can be provided inside or outside the unit 2. It is held between a door 5 and a console 6 on the body side so as to be pivotable about vertical axes 7, 7a, the piston rod being connected, for example, to a hinge 22 of the door 5. When the door 5 is pivoted in the direction of the arrow 8a (opening), a piston 9 of the unit 2 is moved in the direction of the arrow 10 and when it is pivoted in the direction of the arrow 8 (closing), the piston 9 is moved in the direction of the arrow 11. This piston 9 has passage opening 12 for a pressure medium such as gas, hydraulic oil or the like. The openings 12 are opened or closed by an inner valve 13 controlled by a spring 14 depending on the door movement. The line of the device 1 forming the control circuit 3 opens with its inlet and outlet into the working chambers 15 and 16 of the cylinder 25 divided by the piston 9. The blocking valve 4 is arranged in the control circuit 3, acting counter to the flow direction 17. It can be moved into a closed position (arrow direction 23) and into a release position (arrow direction 24) by mechanical actuating means 18 depending on an actuation of a door handle. The blocking valve 4 is on the mechanical Adjustment means 18, which can be formed by a cable or Bowden cable, connected to the inside door handle and the outside door handle. The blocking valve 4 can be moved into the release and closed position via each handle.

Wie Fig. 1 in einem Beispiel näher zeigt, weist der Zylinder 25 der Einheit 2 einen Überströmkanal 26 zwischen den beiden Arbeitskammern 15 und 16 auf. Dieser Kanal 26 erstreckt sich über einen Bereich 27, der einem Öffnungs­winkel der Tür von α 0 bis 30 ° zugeordnet ist, so daß der Kolben 9 bei diesen Öffnungswinkeln in den Kanal 26 eintaucht. Das Medium kann bei eingetauchtem Kolben 9 ungehindert von einer Arbeitskammer 15 in die andere Arbeitskammer 16 überfließen, ohne daß eine Blockierung der Tür 5 erfolgt. Erst wenn der Kolben 9 die strichpunktierte Position (Fig. 1) erreicht hat, ist der Kanal 26 abgesperrt (Fig. 4) und die Tür 5 läßt sich nicht mehr unbehindert öffnen. Eine weitere Öffnung kann erst dann erfolgen, wenn ein Türgriff angezogen und somit das Ventil 4 zum Öffnen in Pfeilrichtung 24 bewegt wird.As FIG. 1 shows in more detail in an example, the cylinder 25 of the unit 2 has an overflow channel 26 between the two working chambers 15 and 16. This channel 26 extends over a region 27 which is assigned an opening angle of the door of α 0 to 30 °, so that the piston 9 is immersed in the channel 26 at these opening angles. When the piston 9 is immersed, the medium can flow freely from one working chamber 15 into the other working chamber 16 without the door 5 being blocked. Only when the piston 9 has reached the dash-dotted position (FIG. 1) is the channel 26 blocked (FIG. 4) and the door 5 can no longer be opened without hindrance. A further opening can only take place when a door handle is tightened and thus the valve 4 is moved to open in the direction of arrow 24.

Die Wirkungsweise der Vorrichtung ist folgende:
Die Tür 5 wird durch Ziehen des Innen- oder Außengriffes geöffnet. Hierdurch wird das Ventil 4 aus seiner Schließstellung in die Frei­gabestellung im Steuerkreis 3 gezogen, so daß ein unbehindertes Öffnen möglich wird. Wenn der Türgriff nicht mehr angezogen ist, nimmt das Ventil 4 eine Blockierstellung ein und die Tür wird in der Augenblicklichen Position festgehalten. Durch den Überströmkanal ist ein freies Öffnen der Tür unabhängig von der Betätigung des Türgriffes bis zu einem Winkel von ca. α = 30 ° möglich, da der Kolben 9 die beiden Kammern 15 und 16 bis zu diesem Winkel nicht absperrt und somit ein freier Mediumfluß zwischen den Kammern 15 und 16 gewährleistet ist. Die Überströmkanäle 26 können nach einer Ausführung gemäß Fig. 2 über den Umfang des Zylinders 25 der Einheit 2 gleichmäßig verteilt angeordnet sein, aber es kann auch nur ein Kanal 26 dem Zylinder 25 zugeordnet sein.The device works as follows:
The door 5 is opened by pulling the inside or outside handle. As a result, the valve 4 is pulled from its closed position into the release position in the control circuit 3, so that an unobstructed opening is possible. When the door handle is no longer tightened, the valve 4 assumes a blocking position and the door is held in the current position. Through the overflow channel a free opening of the door is possible regardless of the actuation of the door handle up to an angle of approximately α = 30 °, since the piston 9 does not shut off the two chambers 15 and 16 up to this angle and thus a free medium flow between the chambers 15 and 16 is guaranteed. According to an embodiment according to FIG. 2, the overflow channels 26 can be arranged uniformly distributed over the circumference of the cylinder 25 of the unit 2, but only one channel 26 can also be assigned to the cylinder 25.
