Abstract
Description
Die Erfindung betrifft einen Betätigungszylinder für hydraulische Kupplungsbetätigungen in Kraftfahrzeugen gemäß dem Oberbegriff des Schutzanspruchs.The The invention relates to an actuating cylinder for hydraulic clutch controls in motor vehicles according to the preamble of the protection claim.
Mit
der
Es ist somit die Aufgabe der Erfindung, einen gattungsgemäßen Betätigungszylinder zu schaffen, bei welchem die Dichtung bei deren Montage ohne Beschädigung das Fenster passieren und zu deren Einbauort gelangen kann.It is thus the object of the invention, a generic actuating cylinder to create, in which the seal during assembly without damaging the Pass windows and get to their installation.
Die Aufgabe wird bei einem gattungsgemäßen Zylinder durch das kennzeichnende Merkmal des Schutzanspruchs gelöst.The Task is in a generic cylinder by the characterizing Feature of the protection claim solved.
Es wird demzufolge ein Betätigungszylinder, insbesondere für hydraulische Kupplungsbetätigungen in Kraftfahrzeugen vorgeschlagen, der ein einseitig durch einen Boden geschlossenes zylinderrohrförmiges Gehäuse umfasst, welches an deren Zylinderfläche mindestens ein Fenster aufweist und wobei an einem Einbauort axial zwischen dem Fenster und dem Gehäuseboden eine Dichtung zur Anlage an der Innenumfangsfläche des Gehäuses vorgesehen ist.It is therefore an actuating cylinder, in particular for hydraulic clutch controls proposed in motor vehicles, the one-sided by a Bottom closed cylinder tube-shaped housing comprises, which at the cylinder surface at least having a window and wherein at a location axially between the window and the caseback a seal is provided for abutment with the inner peripheral surface of the housing.
Bei der Montage der Dichtung muss von dieser das Fenster passiert werden. Dabei überfährt die Dichtung zunächst einen Fenstereintrittswandungsabschnitt, d.h. den Übergang vom Gehäuse zum Fenster. Dieser Übergang ist jedoch für die Dichtung unkritisch im Gegensatz zu einem beim Wiedereintritt in das Gehäuse gebildeten Fensteraustrittswandungsabschnitt. Die Erfinder haben erkannt, dass die Ursache für eine Beschädigung der Dichtung während der Montage in dem zu dieser parallel angeordneten Fensteraustrittswandungsabschnitt zu suchen ist, welcher einen flächigen Angriff und ein zumindest momentanes Zurückhalten der Dichtung verursacht.at the assembly of the seal must be passed by this the window. The seal overflows first a window entry wall section, i. the transition from the case to the window. This transition is however for the seal uncritical as opposed to a reentry in the housing formed Fensteraustrittswandungsabschnitt. The inventors have recognized that the cause of a damage the seal during the assembly in the window exit wall portion arranged parallel thereto to seek, which is a flat Attack and caused at least a momentary retention of the seal.
Davon ausgehend wird vorgeschlagen, dass der einer Umfangsposition der Dichtung zugeordnete Fensteraustrittswandungsabschnitt mit der Dichtung einen Winkel einschließt. Somit kann sich kein großflächiger Kontakt zwischen der Dichtung und dem Fensteraustrittswandungsabschnitt ausbilden, sondern anstelle dessen lediglich ein oder mehrere, im Vergleich dazu relativ kleine Überschneidungsbereiche, welche ein kontinuierliches Eingleiten der Dichtung beim Wiedereintritt in das Gehäuse ermöglichen und wodurch im Ergebnis die Dichtung bei deren Montage das Fenster beschädigungsfrei passieren kann.From that On the basis of this proposal, it is proposed that a circumferential position of the Seal associated Fensteraustrittswandungsabschnitt with the seal a Includes angle. Thus, no large-area contact between the gasket and the window exit wall section instead of merely one or more, in comparison with relatively small overlapping areas, which is a continuous introduction of the seal on reentry in the case allow and As a result, the seal when mounting the window damage can happen.
