Abstract
Stabförmiges Betätigungselement zum Überfragen von Zug- und Druckkräften, wobei das Betätigungselement (10; 20) aus einem elastisch verformbaren Material besteht, das ohne Einwirkung von Verformungskräften quer zur Längsachse die Form eines steifen Querschnittsprofils einnimmt und durch Verformungskräfte quer zur Längsachse in eine aufwickelbare Form bringbar ist, dadurch gekennzeichnet, daß das Betätigungselement (10; 20) aus zwei im Querschnitt etwa V-förmigen Bändern (1, 1'; 21, 21') aufgebaut ist, die im Scheitelbereich miteinander verbunden sind, so dass sich ein X-förmiger Querschnitt ergibt.Rod-shaped actuator for surveying of tensile and compressive forces, wherein the actuating element (10; 20) is made of an elastically deformable material, the without the action of deformation forces transverse to the longitudinal axis takes the form of a stiff cross-sectional profile and transverse by deformation forces to the longitudinal axis can be brought into a rollable form, characterized that this Actuating element (10; 20) of two in cross-section approximately V-shaped bands (1, 1 ', 21, 21') constructed is that are interconnected in the apex area, so that an X-shaped one Cross section results.
Description
Die Erfindung betrifft ein stabförmiges Betätigungselement gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a rod-shaped actuator according to the generic term of claim 1.
Insbesondere bei Mikroaktoren ist der zur Verfügung stehende Einbauraum begrenzt, während andererseits für die Verstellung eines Elements einer Armatur ein bestimmter Hubweg erforderlich ist, der bei einer starren Kolbenstange einen entsprechenden Einbauraum erfordert.Especially with microactuators, the available installation space is limited, while on the other hand for the Adjustment of an element of a fitting required a certain stroke is that with a rigid piston rod a corresponding installation space requires.
Der Erfindung liegt die Aufgabe zugrunde, ein widerstandsfähiges Betätigungselement so auszubilden, dass der Einbauraum unabhängig von der Hublänge möglichst klein gehalten werden kann.Of the Invention is based on the object, a resistant actuator in such a way that the installation space, if possible, regardless of the stroke length can be kept small.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das stabförmige Betätigungselement, im Folgenden Kolbenstange, aufwickelbar ausgebildet wird und bei Anliegen einer Druckkraft bzw. beim Abwickeln ein steifes Profil annimmt. Dadurch, dass die Kolbenstange nicht über die gesamte Hublänge verschoben wird, sondern auf- und abgewickelt wird, kann der Einbauraum insbesondere bei einem Mikroaktor sehr klein gehalten werden. Da das Betätigungselement aus zwei im Querschnitt etwa V-förmigen Bändern aufgebaut ist, die im Scheitelbereich miteinander verbunden sind, ergibt sich ein X-förmiger Querschnitt, und damit ein sehr steifes und gegen Knickkräfte widerstandsfähiges Profil.These Task is inventively characterized solved, that the rod-shaped Actuator in the following piston rod, is formed wound up and at Concerning a compressive force or when unwinding a stiff profile accepts. Because the piston rod is not moved over the entire stroke length is, but is wound up and unrolled, the installation space in particular be kept very small in a microactuator. As the actuator from two in cross-section about V-shaped bands is constructed, which are interconnected in the apex area, results in an X-shaped Cross-section, and thus a very stiff and resistant to buckling resistant profile.
Das Betätigungselement kann beispielsweise zum Übertragen von Zug- und insbesondere Druckkräften dienen, und beispielsweise als eine Kolbenstange, eine Schubstange oder dergleichen ausgebildet sein.The actuator for example, for transfer serve of tensile and especially compressive forces, and for example formed as a piston rod, a push rod or the like be.
