Abstract
Description
Die Erfindung betrifft einen Geberzylinder nach dem Oberbegriff des ersten Patentanspruchs, wobei eine Kolbenstangenaufnahme in einem Kolben vorgesehen ist, der in einem Gehäuse des Geberzylinders axial verschiebbar gelagert ist.The The invention relates to a master cylinder according to the preamble of first claim, wherein a piston rod receptacle in a Piston is provided in a housing of the master cylinder is mounted axially displaceable.

Ein
Geberzylinder für hydraulische Betätigungssysteme,
insbesondere für eine Kupplung oder Bremse eines Kraftfahrzeugs,
mit einem Gehäuse und einem darin axial verschiebbaren
Kolben, der stirnseitig einen Primärdruckraum begrenzt,

Eine
Kolbenstangenanbindung an einen Kolben, insbesondere für
einen Geberzylinder ist ebenfalls aus
Neben einer aufwendigen Montage besteht bei diesen bekannten Kolbenstangenaufnahmen der Nachteil, dass sich der die Kolbenstange aufnehmende Adapter zum Kolben verdrehen kann.Next a complex assembly consists in these known piston rod receptacles the disadvantage that the piston rod receiving adapter can turn to the piston.
Aufgabe der Erfindung ist es, einen Geberzylinder zu schaffen, bei welchem eine einfache montagefreundliche und verdrehsichere Aufnahme des die Kolbenstange befestigenden Adapters gewährleistet ist.task The invention is to provide a master cylinder, in which a simple assembly-friendly and torsion-proof recording of the the piston rod fastening adapter is guaranteed.
Diese Aufgabe wird erfindungsgemäß mit einem Geberzylinder mit den Merkmalen des ersten Patentanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.These Task is inventively with a master cylinder solved with the features of the first claim. advantageous Embodiments emerge from the subclaims.
Der Geberzylinder weist einen axial verschiebbaren Kolben auf, an dem eine Kolbenstange mit ihrem kolbenseitigen Ende mittels eines Adapters schwenkbar befestigt ist, wobei das kolbenseitige Ende der Kolbenstange in einer Ausnehmung des Kolbens sitzt und die Kolbenstange nach ihrem kolbenseitigen Ende eine Einschnürung aufweist, in die der Adapter mit einem Eingriffsbereich eingreifbar ist, wobei der Adapter verdrehsicher am Kolben befestigt ist.Of the Master cylinder has an axially displaceable piston on which a piston rod with its piston-side end by means of an adapter pivotally is attached, wherein the piston-side end of the piston rod in a recess of the piston sits and the piston rod after her piston-side end has a constriction, in which the Adapter is engageable with an engagement region, wherein the adapter is secured against rotation on the piston.
Bevorzugt gewährleistet der hülsenartig ausgebildete Adapter ein Hindurchführen des kolbenseitigen Endes der Kolbenstange, wozu der Eingriffsbereich insbesondere elastisch aufspreizbar ist.Prefers ensures the sleeve-like adapter passing the piston-side end of the piston rod, for which the engagement region is in particular elastically expandable.
Vorzugsweise ist der Eingriffsbereich des Adapters kegelförmig ausgebildet und mit Schlitzen zur Bildung von Lamellen versehen, die die Kolbenstange hinter deren kolbenseitigem Ende umschließen.Preferably the engagement area of the adapter is cone-shaped and provided with slots for the formation of fins that the piston rod enclose behind the piston-side end.
Dazu korrespondiert der kleinste Durchmesser des kegelförmigen Eingriffsbereiches des Adapters mit der Einschnürung. Der Eingriffsbereich ist soweit radial aufweitbar, dass das kolbenseitige Ende der Kolbenstange hindurchführbar ist.To corresponds to the smallest diameter of the cone-shaped Engagement area of the adapter with the constriction. Of the Engagement area is so far radially expandable that the piston side End of the piston rod can be passed.
Der Adapter weist vorteilhafter Weise wenigstens ein Formelement auf, welches mit einem korrespondierenden Formelement des Kolbens verdrehsicher in Eingriff bringbar ist.Of the Adapter advantageously has at least one molding element, which is against rotation with a corresponding form of the piston element can be brought into engagement.
Dazu können am Adapter ein oder mehrere Rastelemente ausgebildet sein, die in korrespondierenden Ausnehmungen des Kolbens einrastbar und bevorzugt federnd ausgebildet sind.To can be formed on the adapter one or more locking elements be latched in corresponding recesses of the piston and are preferably resilient.
Die Rastelemente werden beim Einschieben in eine entsprechende Aufnahmeöffnung des Kolbens radial nach innen gedrückt und federn bei Erreichen der Rastposition radial nach außen, wodurch sie in dafür vorgesehene Ausnehmungen des Kolbens einrasten.The Locking elements are when inserted into a corresponding receiving opening of the piston pressed radially inward and spring upon reaching the locking position radially outward, causing them in for engage provided recesses of the piston.
Dabei kann der Adapter lösbar oder unlösbar am Kolben befestigt werden.there The adapter can be detachable or unsolvable on the piston be attached.
Weiterhin ist am Adapter ein Flansch vorgesehen, der an der kolbenstangenseitigen Stirnseite des Kolbens anliegt.Farther the adapter is a flange provided on the piston rod side Front side of the piston rests.
Es ist möglich, den Adapter und die durch den Adapter ragende Kolbenstange als vormontierte Einheit mit dem Kolben zu verbinden.It is possible the adapter and the through connecting the adapter projecting piston rod as a preassembled unit with the piston.
Alternativ können Kolben und Adapter vormontiert und die Kolbenstange durch Hindurchführen deren kolbenstangenseitigen Endes am Kolben befestigt werden.alternative can pre-assembled pistons and adapters and the piston rod by passing the rod end thereof be attached to the piston.
Mit der erfindungsgemäßen Lösung wird eine überraschend einfache Möglichkeit der verdrehsicheren Befestigung der Kolbenstange am Kolben mit nur einem Bauelement in Form des Adapters geschaffen. Dieser kann z. B. als Spritzgießteil ausgebildet sein.With the solution according to the invention becomes a surprising easy way of twist-proof attachment of the Piston rod on the piston with only one component in the form of the adapter created. This can z. B. formed as an injection molded part be.
