Description

Die Erfindung betrifft eine hydraulische Kupplungsbe­ tätigungs-einrichtung nach dem Oberbegriff des An­ spruchs 1.The invention relates to a hydraulic clutch activity facility according to the preamble of the An saying 1.

Aus dem DE-GM 71 29 822 ist eine derartige Kupplungs­ betätigungs-einrichtung bekannt. Auch in dem DE-GM 88 15 881 und der US PS 47 08 228 sind vom Aufbau her gleiche Kupplungsbetätigungs-einrichtungen gezeigt. Allen Ausführungen ist gemeinsam, daß sie eine zwi­ schen Gehäuse und Kupplungslager angeordnete, das Kupplungslager vorspannende zylindrische Schraubenfe­ der und eine das Gehäuse bzw die Betätigungseinrich­ tung umgebende Abdeckeinrichtung z. B. in Form eines Faltenbalgs aufweisen.Such a coupling is known from DE-GM 71 29 822 actuator known. Also in the DE-GM 88 15 881 and the US PS 47 08 228 are of the construction same clutch actuation devices shown. All versions have in common that they are a two arranged housing and clutch bearing, the Coupling bearing preloading cylindrical screw the one and the housing or the actuating device device surrounding covering device z. B. in the form of a Have bellows.

Die Schraubenfeder und die Abdeckeinrichtung sind Ein­ zelteile, die getrennt voneinander montiert werden müssen, was zusätzliche Lagerhaltung und Montageauf­ wand erfordert. Außerdem benötigen sie axial und ra­ dial Platz.The coil spring and the cover device are on individual parts that are assembled separately need what additional storage and assembly on wall requires. They also need axial and ra dial place.

Die Erfindung hat die Aufgabe, eine Kupplungsbetäti­ gungseinrichtung der eingangs genannten Art so weiter­ zuentwickeln, daß mit einfachen Mitteln eine platzspa­ rende und aus weniger Einzelteilen bestehende Kupp­ lungsbetätigungseinrichtung geschaffen wird. The invention has the task of a clutch actuator supply device of the type mentioned so on develop that with simple means a space saver rende and consisting of fewer individual parts tion actuator is created.  

Die Lösung der Aufgabe gelingt dadurch, daß die Feder als sogenannte Pufferfeder ausgebildet ist. Dadurch lassen sich die drei Erfordernisse, nämlich Lagervor­ spannung, Verdrehsicherung und Abdeckung, mit einem einzigen Element erfüllen, das zudem als allgemein be­ kanntes Maschinenelement im Handel preiswert erhält­ lich ist.The problem is solved in that the spring is designed as a so-called buffer spring. Thereby the three requirements, namely stock pre tension, anti-rotation and cover, with one fulfill only one element, which is also generally considered gets known machine element inexpensively in the trade is.

Die Erfindung soll an einem Ausführungsbeispiel darge­ stellt werden. In der einzigen Figur ist das Kupp­ lungslager mit 1 bezeichnet. Es ist radial einstellbar über eine Anstellfeder 2 auf der Verschiebehülse 3 an­ geordnet, die gleichzeitig als Kolben dient und zusam­ men mit dem Gehäuse 4, welches die Druckmittelzufuhr 5 aufweist, einen Druckraum bildet. Zwischen dem Gehäuse 4 und dem Kupplungslager 1 ist die Pufferfeder 6 ange­ ordnet, die sowohl das Kupplungslager 1 vorspannt und es gegen Verdrehen sichert, als auch als Abdeckung für den Raum dient, den sie umgibt. Somit kann die her­ kömmliche Balgdichtung entfallen.The invention is to be presented in one embodiment Darge. In the single figure, the coupling bearing is designated 1 . It is radially adjustable via an adjusting spring 2 on the sliding sleeve 3 , which also serves as a piston and together with the housing 4 , which has the pressure medium supply 5 , forms a pressure chamber. Between the housing 4 and the clutch bearing 1 , the buffer spring 6 is arranged, which both preloads the clutch bearing 1 and secures it against rotation, and also serves as a cover for the space that surrounds it. Thus, the conventional bellows seal can be omitted.
