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.

Neben einer aufwendigen Montage besteht bei diesen bekannten Kolbenstangenaufnahmen der Nachteil, dass immer zusätzliche Bauteile benötigt werden.Next a complex assembly consists in these known piston rod receptacles the disadvantage that always additional components are needed.
Aufgabe der Erfindung ist es, einen Geberzylinder zu schaffen, bei welchem eine einfache Montage der Kolbenstange ohne zusätzliche Bauteile gewährleistet ist.task The invention is to provide a master cylinder, in which a simple installation of the piston rod without additional Components is guaranteed.
Diese Aufgabe wird durch einen Geberzylinder für hydraulisch betätigbare Kupplungs- oder Bremssysteme gelöst, der ein Gehäuse aufweist, in dem ein Innenraum ausgebildet ist, in welchem ein Kolben entgegen der Rückstellkraft einer Rückstellfeder durch die Betätigung einer Kolbenstange axial verschiebbar ist, wobei die Kolbenstange mit ihrem kugelförmigen Ende in einer kugelkalottenförmigen Ausnehmung des von der Rückstellfeder abgewandten Ende des Kolbens schwenkbar aufgenommen wird und erfindungsgemäß das in Richtung zur Kolbenstange gerichtete Ende des Gehäuses einen Randbereich aufweist, der mit wenigstens einer Aussparung versehen ist, durch die eine Durchmessererweiterung, die sich an das kugelförmige Ende der Kolbenstange anschließt, führbar und relativ zum Gehäuse drehbar ist, derart, dass die Durchmessererweiterung nach der Montage der Kolbenstange sich im Innenraum des Gehäuses auszugsicher hinter einer inneren Anlagefläche des Randbereiches des Gehäuses befindet.These Task is done by a master cylinder for hydraulic actuated clutch or brake systems solved, having a housing in which an interior formed is, in which a piston against the restoring force a return spring by the operation of a Piston rod is axially displaceable, with the piston rod with its spherical end in a spherical cap-shaped recess of the return spring facing away from the end of the piston is pivotally received and according to the invention towards the piston rod directed end of the housing has an edge region which is provided with at least one recess is provided, through which a diameter extension, which adhere connects the spherical end of the piston rod, is rotatable and rotatable relative to the housing, in such a way that the diameter extension after assembly of the piston rod itself in the interior of the housing sure about an inner Contact surface of the edge region of the housing is located.
Dabei wird durch die Druckbeaufschlagung der Rückstellfeder der Kolben mit einer axialen Haltekraft gegen die Kolbenstange gedrückt, so dass die Kolbenstange mit ihrem kugelförmigen Ende in die kugelkalottenförmige Ausnehmung des Kolbens eingreift.there is by the pressurization of the return spring of Piston pressed against the piston rod with an axial holding force so that the piston rod with its spherical end in the spherical cap-shaped recess of the piston engages.
Durch diese erfindungsgemäße Lösung steht die Kolbenstange mit dem Kolben ohne zusätzliche Befestigungselemente immer in Wirkverbindung. Die Montage der Kolbenstange gestaltet sich ebenfalls sehr einfach.By this solution according to the invention is the Piston rod with the piston without additional fasteners always in active connection. The assembly of the piston rod designed also very easy.
Dabei erstreckt sich die Aussparung im Randbereich vorzugsweise wendelartig von einer äußeren Stirnseite des Randbereiches bis zur inneren Anlagefläche des Randbereiches und der Durchmessererweiterung der Kolbenstange ist korrespondierend zu der Aussparung ebenfalls wendelartig ausgebildet.there the recess in the edge region preferably extends helically from an outer end side of the edge region to the inner contact surface of the edge region and the Diameter extension of the piston rod is corresponding to the recess also formed like a helix.
Insbesondere ist die Durchmessererweiterung der Kolbenstange in der Art eines Außengewindes mit z. B. nur 1 bis 3 Gewindegängen ausgebildet.Especially is the diameter extension of the piston rod in the manner of a External thread with z. B. only 1 to 3 threads educated.
Dazu korrespondierend weist die Aussparung im Randbereich des Gehäuses ein Innengewinde auf, welches mit mindestens einem Gewindegang versehen ist.To Corresponding, the recess has in the edge region of the housing an internal thread, which provided with at least one thread is.
Die Kolbenstange wird bei der Montage einfach mit dem Gewinde in der Durchmessererweiterung durch das Innengewinde im Randbereich des Gehäuses geschraubt. Dabei kann der Geberzylinder inklusive Kolben und Rückstellfeder ansonsten fertig montiert sein.The Piston rod is easy to thread with in the assembly Diameter widening through the internal thread in the edge area of the housing screwed. Here, the master cylinder including piston and return spring otherwise be ready assembled.
Die Kolbenstange greift beim Einschrauben mit ihrem kugelförmigen Ende in die kugelkalottenförmige Ausnehmung des Kolbens ein, der durch die Rückstellfeder an das kugelförmige Ende des Kolbens gedrückt wird. Nach dem Hindurchschrauben liegt die Durchmessererweiterung an der inneren Anlagefläche des Randbereiches des Gehäuses auszugsicher an, da in diesem montierten Zustand keine weitere Relativdrehung zwischen Kolbenstange und Gehäuse erfolgt.The Piston rod engages with its spherical when screwing End in the spherical cap-shaped recess of the piston one, which by the return spring to the spherical End of the piston is pressed. After screwing lies the diameter extension on the inner contact surface the edge of the housing on sure, since in this mounted state no further relative rotation between piston rod and housing takes place.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles und zugehöriger Zeichnungen näher erläutert.The Invention will be described below with reference to an embodiment and associated drawings explained in more detail.

Durch die erfindungsgemäße Lösung sind keine zusätzlichen Befestigungsmittel (wie Federringe, Clips, Verbindungshülsen oder ähnliches) für die Montage des Kolbens mehr erforderlich. Der Kolben ist erstmalig nicht mehr mit der Kolbenstange verbunden sondern steht mit dieser nur noch in Wirkverbindung.By the solution according to the invention are none additional fasteners (such as spring washers, clips, Connecting sleeves or the like) for the assembly of the piston more required. The piston is first time no longer connected to the piston rod but stands with this only in active connection.
