Abstract
Description
Die Erfindung betrifft eine Betätigungseinrichtung für eine hydraulische Kupplungsanlage, insbesondere für Reibungskupplungen von Kraftfahrzeugen mit Unterstützung der Betätigungskraft, wobei das Pedal mittels einer Kolbenstange direkt mit einem Kolben eines Geberzylinders verbunden ist. Dadurch ergibt sich je nach Schwenkwinkel des Pedals eine nahezu konstante Übersetzung.The The invention relates to an actuating device for one Hydraulic clutch system, in particular for friction clutches of motor vehicles with support the operating force, the pedal is directly connected to a piston by means of a piston rod a master cylinder is connected. This results depending on Swing angle of the pedal a nearly constant translation.
Aus der JP 60-56 636 ist eine Pedalübersetzung bekannt, bei der ein Seilzug auf einer Auflage mit veränderlichem Durchmesser zu liegen kommt. Nachteilig ist hierbei einerseits der große Schwenkwinkel, den der Seilzug vollführen muss, sowie die eingeschränkte Möglichkeit, die Übersetzung zu variieren, da der Seilzug grundsätzlich tangential auf der Auflage zu liegen kommt.Out JP 60-56 636 is a pedal transmission known in which a cable on a pad with variable Diameter comes to rest. The disadvantage here is on the one hand the size Swing angle, the cable must perform, as well as the limited possibility the translation to vary, as the cable basically tangential to the pad to come to rest.

Aufgabe der Erfindung ist es, eine auf das Pedal seitens eines Ausrücksystems einwirkende Kraft derart zu übersetzen, dass unter Beibehaltung eines vorgegebenen Ausrückweges einer Kupplung und gleichzeitig vorgegebenem maximalem Pedalweg, das Betätigungskraftmaximum abgesenkt wird.task The invention is to provide a pedal on the part of a release system to translate acting force in such a way that while maintaining a predetermined Ausrückweges a clutch and simultaneously predetermined maximum pedal travel, the maximum actuation force is lowered.
Die Aufgabe der Erfindung wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Bei einer Einrichtung zur Pedalkraftreduktion mit einem an einem Pedalbock um einen Drehpunkt gelagerten Pedal, steht die Kolbenstange mit dem Pedal über dessen Länge in mittelbarer formschlüssiger Wirkverbindung. Durch diese über eine mittelbare Wirkverbindung ist es möglich, eine variable Übersetzung zu realisieren. Diese mittelbare Wirkverbindung ist konstruktiv so ausgeführt, dass das Ende der Kolbenstange mit einer mindestens eine Führungsbahn aufweisenden Kulissenscheibe versehen oder mit einer Kulissenstange verbunden ist und am Pedal mindestens eine Führungsrolle vorgesehen ist, die mit dieser Führungsbahn die Wirkverbindung realisiert.The The object of the invention is specified by the in claim 1 Characteristics solved. at a device for pedal force reduction with a on a Pedalbock The pedal is supported around a pivot point over the pedal its length in indirect form-locking operative connection. Through this over an indirect operative connection makes it possible to have a variable ratio to realize. This indirect active compound is constructive so executed, that the end of the piston rod having a at least one guideway Provided link plate or connected to a link rod and at least one leadership role is provided on the pedal, the with this guideway realized the active compound.
Mit dieser konstruktiven Lösung für eine variable Pedalkraftübersetzung ist es in vorteilhafter Weise möglich, auf einfache Art und Weise eine Betätigungskraftanpassung an den jeweiligen Fahrzeugtyp bzw. die darin eingesetzte Kupplung vornehmen zu können. Gegenüber einer konventionellen konstanten Pedalübersetzung steigt die Kraftkennlinie am Anfang der Pedalbetätigung steiler an, flacht sich dann jedoch im Bereich der höchsten Kupplungskräfte aufgrund der sich verändernden Übersetzung stärker ab und bleibt unterhalb der ansonsten maximalen Pedalkräfte eines konventionellen Systems. Die Anpassung an die entsprechende Kupplung erfolgt über die jeweilige Form der Führungsbahnen, wobei die Lage und Anzahl der Führungsrollen unterschiedliche Ausgestaltungen der Führungsbahnen erforderlich machen. So können mehrere Führungsbahnen jeweils eine geschlossene Form haben oder aber auch unterschiedlich ausgeführt sein, indem eine Führungsbahn beispielsweise in sich geschlossen ist und eine andere Führungsbahn eine offene Form aufweist.With this constructive solution for one variable pedal force ratio is it possible in an advantageous manner in a simple way an operating force adjustment to the make the respective vehicle type or the clutch inserted therein to be able to. Across from a conventional constant pedal ratio increases the power curve at the beginning of the pedal operation steeper, but then flattens in the area of highest coupling forces due the changing translation stronger and stays below the otherwise maximum pedal forces of a conventional system. The adaptation to the corresponding coupling done via the respective shape of the guideways, the location and number of guide rollers make different configurations of the guideways required. So can several guideways each have a closed shape or be executed differently, by a guideway for example, is self-contained and another guideway has an open shape.
In vorteilhafter Weiterbildung der Erfindung weist das Ende der Kolbenstange einen Anlenkpunkt auf, über den eine am Pedalbock befestigte Verbindungsstrebe drehbar mit diesem ver bunden ist. Eine kleine Anzahl an miteinander in Wirkverbindung stehenden Bauteile wirkt sich letztendlich positiv auf die Toleranzkette aus.In Advantageous development of the invention, the end of the piston rod a pivot point, over the one attached to the pedal bracket connecting strut rotatable with this connected is. A small number of interacting with each other standing components ultimately has a positive effect on the tolerance chain out.
