Abstract
Description
Die Erfindung betrifft ein Verfahren zur Bearbeitung von Reiblamellen nach dem Oberbegriff des Patentanspruches 1 sowie eine Vorrichtung zur Durchführung des Verfahrens nach dem Oberbegriff des Patentanspruches 3.The The invention relates to a method for processing friction plates according to the preamble of claim 1 and an apparatus to carry out the method according to the preamble of claim 3.
Reiblamellen
werden in Kupplungen oder Bremsen, insbesondere bei Schaltelementen
von Automatikgetrieben für
Kraftfahrzeuge eingesetzt. Reiblamellen weisen ein ringförmiges Trägerblech, vorzugsweise
aus Stahl auf, auf dessen beiden Seiten papierartige Reibbeläge aufgebracht,
insbesondere aufgeklebt und aufgepresst sind. Ein Verfahren zur
Herstellung von Reiblamellen mit Reibbelägen wurde durch die
Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zur nachträglichen Bearbeitung von Reiblamellen bereitzustellen, wodurch eine gleichmäßige Dicke erzielbar ist. Ferner ist es Aufgabe der Erfindung, eine geeignete Vorrichtung zur Durchführung des Verfahrens vorzuschlagen.It Object of the present invention, a method for subsequent To provide processing of friction plates, whereby a uniform thickness is achievable. It is another object of the invention to provide a suitable Apparatus for carrying out to propose the procedure.
Die Aufgabe der Erfindung wird einerseits durch die Merkmale des Patentanspruches 1 und andererseits durch die Merkmale des Patentanspruches 3 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object of the invention is on the one hand by the features of claim 1 and on the other hand solved by the features of claim 3. advantageous Embodiments emerge from the subclaims.
Nach dem erfindungsgemäßen Verfahren wird ein Satz von Reiblamellen – entweder Innenlamellen oder Außenlamellen – mit einem Satz von Reibscheiben, welche raue, „abrasive" Reibflächen aufweisen, in einer Vorrichtung aufgenommen, mit einer Axialkraft zur Erzielung einer axialen Anpressung von Reibscheiben und Reiblamellen beaufschlagt und in Relativbewegung zueinander versetzt. Entweder werden die Reibscheiben in der Vorrichtung festgehalten, und die Reiblamellen (Innenlamellen) werden in Drehbewegung versetzt, oder die Reiblamellen (Außenlamellen) werden durch die Vorrichtung festgehalten, und die Reibscheiben werden in Rotation versetzt. Infolge des axialen Druckes und der Relativbewegung zwischen den Reibbelägen und den rauen Reibscheiben erfolgt eine partielle Abtragung an den Reibbelägen, welche zu einer Vergleichmäßigung der Reiblamellendicke führt. Gleichzeitig wird eine nach der Fertigung vorhandene glatte Oberfläche (Harzschicht) der Reiblamellen abgetragen, sodass die Oberfläche der Reibbeläge poröser wird. Damit wird der Vorteil einer gleichmäßigeren Drehmomentübertragung im Schaltelement erreicht.To the method according to the invention is a set of friction plates - either Inner fins or outer fins - with one Set of friction discs, which have rough, "abrasive" friction surfaces, in a device recorded, with an axial force to achieve an axial contact pressure of Friction discs and friction plates acted upon and in relative motion offset from each other. Either the friction discs in the device held, and the friction plates (inner plates) are in rotational movement offset, or the friction plates (outer plates) are through the Device held, and the friction discs are in rotation added. Due to the axial pressure and the relative movement between the friction linings and the rough friction discs is a partial removal of the friction linings, which to a homogenization of Friction lamella thickness leads. At the same time, there is a smooth surface (resin layer) after finishing worn off the friction plates, so that the surface of the friction linings is more porous. In order to The advantage of a more even torque transmission achieved in the switching element.
Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens besteht aus einem Hohlzylinder mit einem Mitnahmeprofil (Innenverzahnung), welches dem Mitnahmeprofil (Außenverzahnung) von bekannten Reiblamellen (Außenlamellen) entspricht. Die Vorrichtung besteht ferner aus einem Zylinder, welcher auf seinem Umfang ein Mitnahmeprofil (Außenverzahnung) aufweist, welches dem Mitnahmeprofil (Innenverzahnung) von bekannten Reiblamellen (Innenlamellen) entspricht. Die Vorrichtung umfasst ferner je einen Satz von Reibscheiben, die entweder ein äußeres oder inneres Mitnahmeprofil aufweisen. Schließlich gehört zu der erfindungsgemäßen Vorrichtung ein axial ver schiebbarer Ringkolben, welcher eine Axialkraft auf das Paket von Reibscheiben und Reiblamellen ausübt. Grundsätzlich kann der Hohlzylinder, d. h. der äußere Teil der Vorrichtung zur Aufnahme von Außenlamellen feststehen und der Zylinder, d. h. der innere Teil der Vorrichtung zur Aufnahme von Innenlamellen rotieren oder umgekehrt, d. h. der innere Teil steht fest und der äußere Teil der Vorrichtung rotiert. Mit dieser Vorrichtung ist es möglich, serienmäßig hergestellte Reiblamellen einer weiteren Bearbeitung zu unterziehen, welche eine gleichmäßig Dicke der Reiblamellen zum Ergebnis hat. Damit wird beim Einsatz der Reiblamellen in Schaltelementen ein gleichmäßiger Drehmomentverlauf erzielt und das Auftreten von Drehschwingungen vermieden.The inventive device to carry out the method consists of a hollow cylinder with a driving profile (Internal toothing), which is the driving profile (external toothing) of known friction plates (outer plates) corresponds. The device further consists of a cylinder, which on his Perimeter of a driving profile (external toothing) having, which the driving profile (internal toothing) of known friction plates (Inner plates) corresponds. The device further comprises one each Set of friction discs that have either an outer or inner driving profile exhibit. After all belongs to the device according to the invention an axially ver sliding ring piston, which has an axial force the package of friction discs and friction plates exerts. Basically, the hollow cylinder, d. H. the outer part stand firm the device for receiving outer plates and the cylinder, d. H. the inner part of the device for receiving rotate from inner plates or vice versa, d. H. the inner part is fixed and the outer part the device rotates. With this device, it is possible to mass-produced Reiblamellen subject to further processing, which is a even thickness the friction lamellae has the result. This is when using the friction plates in switching elements a uniform torque curve achieved and avoids the occurrence of torsional vibrations.
