Abstract
Description
Die vorliegende Erfindung betrifft einen Nehmerzylinder, insbesondere für ein hydraulisches Ausrücksystem einer Reibungskupplung eines Kraftfahrzeuges, mit einem Nehmerzylindergehäuse, das konzentrisch zu einer Getriebeeingangswelle angeordnet ist, wobei eine Führungshülse in einer Längsbohrung des Nehmerzylindergehäuses radial beabstandet zur Bildung eines kreisringförmigen Druckraums angeordnet ist und in dem Druckraum ein Ringkolben, der druckraumseitig mit einer Dichtung versehen ist, axial verschiebbar geführt ist.The The present invention relates to a slave cylinder, in particular for a hydraulic release system of a friction clutch a motor vehicle, with a slave cylinder housing, which is arranged concentrically to a transmission input shaft, wherein a guide sleeve in a longitudinal bore the slave cylinder housing radially spaced to form a circular pressure chamber is arranged and in the pressure chamber an annular piston, the pressure chamber side provided with a seal is, is guided axially displaceable.

Eine Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Nehmerzylinder bereitzustellen, bei dem der Ringkolben aus einem alternativen Material gefertigt ist. Eine weitere Aufgabe der vorliegenden Erfindung ist es, einen Nehmerzylinder bereitzustellen, bei dem der Ringkolben kostengünstiger als durch ein bekanntes Spritzgussbauteil realisiert werden kann.A Object of the present invention is to provide a generic To provide slave cylinder, wherein the annular piston of a alternative material is made. Another task of the present Invention is to provide a slave cylinder, wherein the ring piston cheaper than by a known Injection molded component can be realized.
Dieses Problem wird gelöst durch einen Nehmerzylinder, insbesondere für ein hydraulisches Ausrücksystem einer Reibungskupplung eines Kraftfahrzeuges, mit einem Nehmerzylindergehäuse, das konzentrisch zu einer Getriebeeingangswelle angeordnet ist, wobei eine Führungshülse in einer Längsbohrung des Nehmerzylindergehäuses radial beabstandet zur Bildung eines kreisringförmigen Druckraums angeordnet ist und in dem Druckraum ein Ringkolben, der druckraumseitig mit einer Dichtung versehen ist, axial verschiebbar geführt ist, wobei der Ringkolben aus einem umgeformten Blechteil besteht. Der Ringkolben wird dabei vorzugsweise durch Stanzbiegen hergestellt, wobei zusätzlich Teile des Ringkolbens beispielsweise durch Tiefziehen oder dergleichen hergestellt sein können. Durch Blechumformung hergestellte Bauteile sind heutzutage sehr kostengünstig in großer Stückzahl zu fertigen, sodass dies eine kostengünstige Alternative zu einem Ringkolben nach Stand der Technik ist.This Problem is solved by a slave cylinder, in particular for a hydraulic release system of a friction clutch a motor vehicle, with a slave cylinder housing, which is arranged concentrically to a transmission input shaft, wherein a guide sleeve in a longitudinal bore the slave cylinder housing radially spaced to form a circular pressure chamber is arranged and in the pressure chamber an annular piston, the pressure chamber side provided with a seal is axially slidably guided, wherein the annular piston consists of a formed sheet metal part. The ring piston is doing preferably produced by stamping, in addition Parts of the annular piston, for example by deep drawing or the like can be made. Made by sheet metal forming Components are very inexpensive today in large To produce a quantity, so this is a cost-effective Alternative to a ring piston according to the prior art.
Vorzugsweise weist der Ringkolben an der dem Druckraum zugewandten Seite eine stirnseitig umlaufende Nut zur Aufnahme eines Dichtungsfußes der Dichtung auf. Die Dichtung weist dazu vorzugsweise eine radial innere und eine radial äußere Dichtlippe auf, die in einem Full punkt zusammenlaufen, der wiederum in einen im Schnitt trapezförmigen Dichtungsfuß übergeht. Dazu weist die stirnseitig umlaufende Nut vorzugsweise ebenfalls einen trapezförmigen Querschnitt auf. Durch den trapezförmigen Querschnitt sowohl von Dichtungsfuß als auch der umlaufenden Nut wird eine formschlüssige Verbindung zwischen der Ringdichtung und dem Ringkolben erzielt, wobei die formschlüssige Verbindung durch einfaches Eindrücken des Dichtungsfußes in die umlaufende Nut hergestellt wird.Preferably has the annular piston on the pressure chamber side facing a frontally circumferential groove for receiving a sealing foot of the Seal on. The seal preferably has a radially inner and a radially outer sealing lip, which in a full point converge, in turn, in an average trapezoidal sealing foot merges. For this purpose, the frontally circumferential groove preferably also a trapezoidal cross section. By the trapezoidal Cross-section of both sealing foot and the peripheral Groove becomes a positive connection between the ring seal achieved and the annular piston, wherein the positive connection by simple impressions of the seal foot in the circumferential groove is produced.
Der Ringkolben weist an der dem Druckraum abgewandten Seite vorzugsweise eine Ringnut zur Aufnahme eines Lagerinnenringes eines Ausrücklagers auf. Das Ausrücklager kann so unmittelbar mit dem Ringkolben verbunden werden, beispielsweise indem ein nach Art einer Schnappverbindung gestalteter Bereich des Lagerinnenringes auf die Nut aufgeschoben wird. Der Lagerinnenring weist dazu vorzugsweise eine zumindest teilweise radial verlaufende Scheibe mit einem zylindrisch verlaufenden Bereich an der Innenseite sowie aus der Scheibe herausgebogene und teilweise ausgestanzte Federlaschen auf.Of the Ring piston has at the side facing away from the pressure chamber preferably an annular groove for receiving a bearing inner ring of a release bearing on. The release bearing can thus directly with the ring piston be connected, for example by a snap-in type Shaped area of the bearing inner ring pushed onto the groove becomes. The bearing inner ring preferably has at least one partially radially extending disc with a cylindrically extending Area on the inside as well as out of the disc and bent partially punched spring tabs on.
Die Ringnut wird vorzugsweise durch zwei radial verlaufende Ringe gebildet. Die radial verlaufenden Ringe wiederum werden vorzugsweise durch Bördel gebildet, sodass ein dem Druckraum abgewandter Ring und/oder ein dem Druckraum zugewandter Ring nach Art eines Bördelflansches ausgeführt ist.The Ring groove is preferably formed by two radially extending rings. The radially extending rings in turn are preferably by crimping formed so that a pressure chamber facing away from the ring and / or a the pressure chamber facing ring in the manner of a Bördelflansches is executed.
Vorzugsweise ist vorgesehen, dass der Innendurchmesser des Ringkolbens im Bereich der Ringnut vergrößert ist, sodass dieser über einen Sicherungsring, der als Anschlag und Wegbegrenzung für den Ringkolben dient, ragen kann.Preferably is provided that the inner diameter of the annular piston in the range the annular groove is enlarged so that this over a retaining ring, which serves as a stop and Wegbegrenzung for the ring piston serves, can protrude.
