Description
Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft eine hydraulisch betätigte Ausrückvorrichtung für eine Reibungskupplung von Fahrzeugen, ausgebildet als Nehmerzylinder, der ein stirnseitig an einem Getriebegehäuse angeordnetes Druckgehäuse umfaßt, das konzentrisch zu einer Getriebeeingangswelle eingesetzt ist und in dessen Längsbohrung eine Führungshülse radial beabstandet angeordnet ist, die einen kreisringförmigen Druckraum radial innenseitig begrenzt, in dem ein Ringkolben geführt ist, der an einer dem Getriebegehäuse abgewandten Seite über ein Ausrücklager mit der Reibungskupplung verbunden ist und die Führungshülse getriebeseitig über einen Ringflansch am Druckgehäuse befestigt ist.The The invention relates to a hydraulically operated release device for a friction clutch of Vehicles, designed as a slave cylinder, the front side on a gearbox arranged pressure housing comprises which is used concentrically to a transmission input shaft and in its longitudinal bore a guide sleeve radially is arranged at a distance, the an annular pressure chamber radially inside limited, in which an annular piston is guided, which faces away from the gear housing Page over a release bearing is connected to the friction clutch and the guide sleeve on the transmission side via a Ring flange on the pressure housing is attached.

Der Erfindung liegt die Aufgabe zugrunde, eine Führungshülse kostengünstig am Druckgehäuse zu befestigen und eine Zentrierung der Ausrückvorrichtung am Getriebe zu realisieren.Of the Invention has for its object to attach a guide sleeve cost-effective on the pressure housing and a centering of the release device to realize on the gearbox.
Zusammenfassung der ErfindungSummary of the invention
Mit den Merkmalen des kennzeichnenden Teils von Anspruch 1 wird diese zuvor genannte Aufgabe gelöst. Erfindungsgemäß ist am Ringflansch der Führungshülse zumindest eine radial nach innen gerichtete Verstemmung an einer Außenwandung der Ausnehmung des Druckgehäuses vorgesehen und die Zentrierung der Ausrückvorrichtung am Getriebe wird dadurch realisiert, dass der Ringflansch über eine Schulter des Druckgehäuses geführt wird, die bei der Verbindung mit dem Getriebe in das Getriebegehäuse hineinragt. Durch diese Maßnahme ist einerseits eine wirksame drehfeste, unlösbare Befestigung der Führungshülse am Druckgehäuse sichergestellt und andererseits wird die Ausrückvorrichtung am Getriebe zentriert. Durch die erfindungsgemäße, kostengünstig herstellbare Verstemmung stellt sich eine örtlich radiale Überdeckung in Form von Haltenasen ein, die keinerlei spangebende Bearbeitung erfordern. In vorteilhafter Weise ermöglicht diese Verstemmung bei Bedarf ein einfaches Austauschen der Führungshülse bzw. begünstigt die Recyclefähigkeit der Ausrückvorrichtung, d. h. eine Trennung der aus unterschiedlichen Werkstoffen hergestellten Bauteile, Druckgehäuse und Führungshülse des Nehmerzylinders.With the features of the characterizing part of claim 1 becomes this solved the aforementioned problem. According to the invention is Ring flange of the guide sleeve at least a radially inwardly directed caulking on an outer wall of the Recess of the pressure housing provided and the centering of the release device on the transmission is realized in that the annular flange is guided over a shoulder of the pressure housing, the protrudes in the connection with the transmission in the transmission housing. By this measure On the one hand, an effective rotationally fixed, non-detachable fastening of the guide sleeve on the pressure housing is ensured and on the other hand, the release device is on Gear centered. By the inventive, inexpensive producible caulking turns a local radial coverage in the form of retaining lugs that do not require any machining. In an advantageous manner allows this caulking if necessary, a simple replacement of the guide sleeve or favored the recyclability of the disengaging, d. H. a separation made of different materials Components, pressure housing and guide sleeve of Slave cylinder.
Weitere, vorteilhafte Ausgestaltungen der Erfindung beschreiben die Ansprüche 2 bis 5.Further, advantageous embodiments of the invention describe the claims 2 to 5th
Zur weiteren Funktionsverbesserung der Führungshülsenbefestigung ist erfindungsgemäß vorgesehen, mehrere umfangsverteilte Verstemmungen vorzusehen. Alternativ bietet es sich an, eine umlaufende Verstemmung anzuordnen, d. h. der Ringflansch ist am gesamten Umfang durch eine Verstemmung am Druckgehäuse lagepositioniert.to further functional improvement of the guide sleeve fastening is provided according to the invention, provide several circumferentially distributed caulking. Alternatively offers It is to arrange a circumferential caulking, d. H. the ring flange is positionally positioned on the entire circumference by caulking the pressure housing.
Eine bevorzugte Ausbildung der Verstemmung sieht vor, daß stirnseitig am Druckgehäuse der Ausnehmung benachbart axial vorstehende Ansätze angeordnet sind, beispielsweise in Form von Gußnoppen, die ein vereinfachtes spanloses Umformen ermöglichen. Dabei bietet es sich an, die vorstehenden Ansätze lediglich sektionsweise, d. h. in einem Teilbereich zu verstemmen, so daß diese eine Mehrfachverstemmung ermöglichen, insbesondere im Hinblick auf einen beispielsweise verschleißbedingten Austausch der Führungshülse.A preferred embodiment of the caulking provides that the front side at the pressure housing the recess adjacent axially projecting lugs are arranged, for example in the form of cast studs, which allow a simplified chipless forming. It is suitable on, the above approaches only in sections, d. H. caulking in a subarea, so that this enable multiple caulking, in particular with regard to a wear-related example Replacement of the guide sleeve.
Zur Schaffung einer verbesserten drehgesicherten Befestigung des Ringflansches am Druckgehäuse ist die Randzone des Ringflansches beispielsweise mit der Wandung der Ausnehmung durch ein ineinandergreifendes bzw. verrastendes Profil formschlüssig verbunden. Dazu bietet es sich vorzugsweise an, ein umlaufendes oder partiell angeordnetes Verzahnungsprofil vorzusehen.to Creation of an improved rotationally secured attachment of the annular flange at the pressure housing is the edge zone of the annular flange, for example, with the wall the recess by an interlocking or latching Profile form-fitting connected. For this purpose, it preferably offers, a circumferential or to provide a partially arranged tooth profile.
