Description
Die Erfindung betrifft ein Kolben-Zylinderaggregat mit einer Mittellängsachse, einem ersten Ende, einem zweiten Ende, einem mit einem Fluid gefüllten Zylinder, einem in dem Zylinder verschiebbar angeordneten Kolben, der den Zylinder in einen dem ersten Ende nahen ersten Arbeitsraum und einen dem ersten Ende fernen zweiten Arbeitsraum unterteilt, einem weiteren in dem Zylinder entlang der Mittelachse bewegbar angeordneter Kolben, der den zweiten Arbeitsraum im Zylinder in einen ersten, dem zweiten Ende fernen ersten Teilarbeitsraum und einen zweiten, dem zweiten Ende nahen zweiten Teilarbeitsraum unterteilt, einer, an dem die beiden Arbeitsräume teilenden Kolben angeordneten Kolbenstange, die den ersten Arbeitsraum durchragt und konzentrisch zur Mittellängsachse an dem ersten Ende durch eine Führungs- und Dichtungseinrichtung abgedichtet und axial bewegbar aus dem Zylinder herausgeführt ist, wobei sich an dem nach außen ragenden Ende der Kolbenstange eine erste Anschlußvorrichtung befindet, und einer, an dem die beiden Teilarbeitsräume teilenden weiteren Kolben angeordneten weitere Kolbenstange, die den zweiten Teilarbeitsraum durchragt und konzentrisch zur Mittellängsachse an dem zweiten Ende durch eine Führungs- und Dichtungseinrichtung abgedichtet und axial bewegbar aus dem Zylinder herausgeführt ist, wobei sich an dem nach außen ragenden Ende der weiteren Kolbenstange eine zweite Anschlußvorrichtung befindet.The invention relates to a piston-cylinder unit having a central longitudinal axis, a first end, a second end, a cylinder filled with a fluid, a displaceably arranged in the cylinder piston, the cylinder in a first end near the first working space and the first end divided second distant working space, another in the cylinder along the central axis movably arranged piston dividing the second working space in the cylinder in a first, the second end distant first part working space and a second, the second end near the second part working space, one on which the two working chambers dividing piston arranged piston rod which projects through the first working space and concentrically sealed to the central longitudinal axis at the first end by a guiding and sealing means and axially movable out of the cylinder, wherein at the outwardly projecting end of the piston rod, a first Anschlußvorrichtu ng is located, and one on which the two sub-working spaces dividing further piston arranged further piston rod which projects through the second part of working space and sealed concentrically to the central longitudinal axis at the second end by a guide and sealing device and axially movable out of the cylinder, which is at the outwardly projecting end of the further piston rod is a second connecting device.
Derartige Kolben-Zylinderaggregate werden in vielen Bereichen eingesetzt, um verschieden Bauteile relativ zu anderen Bauteilen zu bewegen, beispielsweise an Klappen, Hauben, Türen oder dergleichen für Kraftfahrzeuge, Möbel, Maschinen usw.Such piston-cylinder units are used in many areas to move various components relative to other components, such as flaps, hoods, doors or the like for motor vehicles, furniture, machinery, etc.
Bei Klappen, insbesondere bei Heckklappen von Fahrzeugen ist es häufig gewünscht, dass die Klappe von dem Kolben-Zylinderaggregat nicht immer bis in ihre Öffnungsposition sondern nur bis in eine Zwischenposition bewegt wird.For flaps, especially for tailgates of vehicles, it is often desired that the flap of the piston-cylinder unit is not always moved to its open position but only to an intermediate position.
Der Grund dafür kann darin liegen, dass das Kraftfahrzeug z. B. an niedrigen Unterstellplätzen abgestellt werden soll, bei denen ein Öffnen bis in die Öffnungsposition zum einem Anschlagen der Klappe an der Decke führen würde.The reason for this may be that the motor vehicle z. B. should be parked at low parking spaces in which an opening would lead to a striking the flap on the ceiling to the open position.
Ein anderer Grund kann darin liegen, dass die Person, die das Kraftfahrzeug benutzt, nicht groß genug ist, die geöffnete Klappe zum Schließen zu erreichen.Another reason may be that the person using the motor vehicle is not tall enough to reach the open door to close.

Aufgabe der Erfindung ist es ein Kolben-Zylinderaggregat der eingangs genannten Art zu schaffen, das bei einfachem Aufbau wahlweise eine Öffnung einer Klappe bis zu einer Zwischenposition oder bis zur Öffnungsposition ermöglicht.The object of the invention is to provide a piston-cylinder unit of the type mentioned above, which allows a simple construction, optionally opening a flap to an intermediate position or to the open position.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in dem Bereich der Teilarbeitsräume an der Innenwand des Zylinders ein Innengewinde vorhanden ist, das mit einem an dem die beiden Teilarbeitsräume teilenden weiteren Kolben ausgebildeten Außengewinde zusammenwirkt, wobei der weitere Kolben mittels der Gewindeverbindung aus Innengewinde und Außengewinde im eingebauten Zustand durch Drehen am Zylinder und im ausgebauten Zustand durch Drehen an der zweiten Kolbenstange in axialer Richtung entlang der Mittellängsachse verstellbar ist, wobei der zweite Arbeitsraum, der erste Teilarbeitsraum und der zweite Teilarbeitsraum miteinander verbunden sind.This object is achieved in that in the region of the partial work spaces on the inner wall of the cylinder, an internal thread is present, which cooperates with an on the two sub-working spaces dividing further piston formed external thread, wherein the further piston by means of the threaded connection of internal thread and external thread in installed state by turning the cylinder and in the disassembled state by rotating the second piston rod in the axial direction along the Center longitudinal axis is adjustable, wherein the second working space, the first sub-work space and the second sub-work space are interconnected.
In einer vorteilhaften Ausgestaltung ist das Innengewinde an einer im Zylinder angeordneten Gewindehülse ausgebildet, wodurch bereits in der Serienfertigung hergestellte Teile verwendet werden können.In an advantageous embodiment, the internal thread is formed on a threaded sleeve arranged in the cylinder, whereby parts already produced in mass production can be used.
