Description
Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft eine Reibpaarung mit wenigstens einem ersten Reibkörper und einem zweiten Reibkörper als Gegenkörper.The The invention relates to a friction pair with at least one first friction body and a second friction body as a counterbody.
Hintergrund der Erfindungbackground the invention
Eine derartige Reibpaarung wird beispielsweise in synchronisierten Schalt- oder Wechselgetrieben in Kraftfahrzeugen verwendet, bei der beim Schalten ein auf einer Welle frei drehbares Zahnrad durch axiales Anpressen eines Synchronrings an einen dem Zahnrad zugeordneten Kuppelring in Gleichlauf mit der Welle gebracht wird. Die Übertragung der Kräfte von einer auf der Welle drehfesten, aber axial verschiebbaren Schiebemuffe erfolgt über eine axiale oder radiale Sperr- und/oder Mitnehmerverzahnung auf den Synchronring. Anschließend wird das Zahnrad durch weiteres axiales Verschieben der Schiebemuffe, die dann in eine Mitnehmerverzahnung des Kuppelringes eingreift, formschlüssig mit der Welle verbunden. Zur Erreichung eines Gleichlaufs zwischen Syn chronring und Zahnrad weist der Synchronring außen- oder innenkonische Reibflächen auf, die beim axialen Anpressen des Synchronringes mit entsprechenden Gegenflächen am Kuppelring in Kontakt kommen und durch auftretenden Reibschluss den zum Durchschalten der formschlüssigen Kupplung erforderlichen Gleichlauf herstellen. Darüber hinaus kann bei einer sogenannten Doppelkonussynchronisierung zwischen diesen Reibflächen ein Reibring angeordnet sein.A Such friction pairing is used for example in synchronized shift or gearboxes used in motor vehicles when switching a freely rotatable on a shaft gear by axial pressing a synchronizer ring to a gear wheel associated with the coupling ring is brought into synchronism with the shaft. The transmission of forces of a rotationally fixed on the shaft, but axially displaceable sliding sleeve done via a axial or radial locking and / or driving teeth on the Synchronizer ring. Subsequently, will the gear by further axial displacement of the sliding sleeve, which then engages in a driver toothing of the coupling ring, form-fitting connected to the shaft. To achieve a synchronization between Syn chronring and gear has the synchronizer ring outside or internal conical friction surfaces on, in the axial pressing of the synchronizer ring with corresponding Counter surfaces on Coupling ring come into contact and by friction occurring required for switching through the form-locking coupling Create synchronous operation. About that In addition, in a so-called double-cone synchronization between these friction surfaces a friction ring may be arranged.
Als bekannte technische Lösungen werden in Synchronisiereinrichtungen, in denen kegelförmige Reibflächen aufeinander wirken, Reibpaarungen mit verschiedenen Gleitreibwerkstoffen verwendet wie z. B. Sondermessinge, Bronzen, molybdän-, oxid- oder mehrstoffbeschichtete Oberflächen, die gegen eine gehärtete Stahlfläche reiben.When known technical solutions are in synchronizers, in which conical friction surfaces to each other act, friction mating with different Gleitreibwerkstoffen used such as B. special brasses, bronzes, molybdenum, oxide or multi-material coated Surfaces, against a hardened steel surface rub.

Zusammenfassung der ErfindungSummary the invention
Der Erfindung liegt daher die Aufgabe zugrunde, eine leistungsfähige und gleichzeitig kostengünstige Reibpaarung zu entwickeln, welche einen geringen adhäsiven und abrasiven Verschleiß aufweist und sich dabei einfach herstellen lässt.Of the Invention is therefore based on the object, a powerful and at the same time cost-effective Friction pairing to develop, which has a low adhesive and has abrasive wear and easy to make.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil des Anspruchs 1 dadurch gelöst, dass zumindest die Oberflächen des ersten Reibkörpers einen Titandioxidanteil aufweist und dass die des zweiten Reibkörpers aus einem randzonenmodifiziertem Eisenwerkstoff ausgebildet ist.According to the invention this object is achieved by the characterizing part of claim 1 solved that at least the surfaces of the first friction body has a titanium dioxide content and that the second friction body is formed of a randzonenmodifiziertem iron material.
Für die Randzonenmodifizierung eignen sich besonders thermische Diffusionsverfahren. Dabei wird erfindungsgemäß vorzugsweise eine Nitrier-, Nitrocarburier- oder Carbonitrierbehandlung eingesetzt. Durch diese Behandlung entstehen Nitride bzw. Carbonitride, die bevorzugt in der Randschicht angereichert sind. Durch diese auch Verbindungsschicht und im folgenden Reibschicht genannte Schicht wird der metallische Charakter der Oberfläche nochmals verändert, so dass dieser zweite Reibkörper äußeren mechanischen Angriffen einen größeren Widerstand entgegensetzen kann. Die zweite Randschicht weist in besonders vorteilhafter Weise im Falle des Nitrierens oder Nitrocarburierens eine Dicke von 5 bis 20 Mikrometern und im Falle des Carbonitrierens eine Dicke von 100 bis 500 Mikrometern auf.For the edge zone modification Thermal diffusion processes are particularly suitable. It will according to the invention preferably a nitriding, nitrocarburizing or carbonitriding treatment used. By this treatment arise nitrides or carbonitrides, the preferably enriched in the surface layer. Through this too Connecting layer and in the following friction layer called the metallic character of the surface is changed again, so that this second friction body is external mechanical Attacks a greater resistance can oppose. The second edge layer is particularly advantageous In the case of nitriding or nitrocarburizing, a thickness from 5 to 20 microns and in the case of carbonitriding a thickness from 100 to 500 microns.
Erfindungsgemäß weist die Kombination des ersten und zweiten Reibkörpers einen für die Anwendung geeigneten Reibungskoeffizienten auf. Es wird die Adhäsion zum Verschleißpartner verringert und die Abriebfestigkeit erhöht. Wie aus Anspruch 6 hervorgeht, eignen sich dafür besonders Nitrierstähle wie beispielsweise 34CrAr6, 34CrAlNi7, 31CrMo12, 31CrMoV9, 39CrMoV13-9, 34CrAlMo5, 41CrAlMo7 und 15CrMoV5-9, aber auch 1000r6, 80Cr2 und 16MnCr5.According to the invention the combination of the first and second friction body one for the application suitable coefficient of friction. It becomes the adhesion to wear partner reduces and increases the abrasion resistance. As is apparent from claim 6, are suitable for it especially nitriding steels like for example 34CrAr6, 34CrAlNi7, 31CrMo12, 31CrMoV9, 39CrMoV13-9, 34CrAlMo5, 41CrAlMo7 and 15CrMoV5-9, but also 1000r6, 80Cr2 and 16MnCr5.
Erfindungsgemäß wirkt der so behandelte zweite Reibkörper mit dem ersten Reibkörper zusammen. Letzterer ist aus Titandioxid bzw. weist an seiner Oberfläche eine erste Reibschicht aus Titandioxid auf. Die erste Reibschicht kann mit herkömmlichen thermischen Spritzverfahren hergestellt werden. Er ist vorzugsweise spritzrau, und die Oxidkeramik ist nicht mit weiteren Bestandteilen versetzt. Es entfällt einerseits ein aufwändiges Anfertigen einer Legierung und andererseits ist das Herstellverfahren sehr einfach, weil der Arbeitsgang des Glättens und Kalibrierens eingespart wird. Dadurch sind Material und Herstel lungsverfahren sehr kostengünstig.Acts according to the invention the second friction body treated in this way with the first friction body together. The latter is made of titanium dioxide or has on its surface a first friction layer of titanium dioxide. The first friction layer can with conventional thermal spraying process are produced. He is preferable spray-gray, and the oxide ceramic is not with other ingredients added. It is omitted on the one hand a complex Making an alloy and on the other hand, the production process is very simply because the operation of smoothing and calibrating saved becomes. This material and manufacturing process are very cost-effective.
Die
Titandioxid-Reibschicht in Kombination mit ihrem Reibpartner weist
eine sehr geringe Verschleißneigung
auf, gleichzeitig zeigt sie einen konstanten Reibwert über die
Lebensdauer. Im Gegensatz zu der aus
Die Titandioxidschicht wird vorzugsweise durch ein thermisches Spritzverfahren aufgebracht. In Frage kommen Spritzverfahren wie Plasmaspritzen, Flammspritzen, Drahtlichtbogenspritzen oder Hochgeschwindigkeitsflammspritzverfahren. Neben dem thermischen Spritzen sind auch andere Verbindungsarten zwischen Reibschicht und Grundkörper möglich. So kann die Reibschicht auch auf den Grundkörper aufgeklebt oder aufgesintert werden. In besonders vorteilhafter Ausführung weist die Titandioxidschicht eine Dicke von 20 bis 100 Mikrometern, eine Rauigkeit von 10 bis 50 Mikrometern und eine Härte von 600 bis 1000 HV auf.The Titanium dioxide layer is preferably by a thermal spraying method applied. In question come spray methods such as plasma spraying, Flame spraying, wire arc spraying or high speed flame spraying. In addition to the thermal spraying are also other types of connection between friction layer and body possible. So The friction layer can also be glued or sintered onto the base body become. In a particularly advantageous embodiment, the titanium dioxide layer a thickness of 20 to 100 microns, a roughness of 10 to 50 microns and a hardness from 600 to 1000 HV.
Die Beschichtung ist besonders einfach zu realisieren, weil außer Titandioxid keine zusätzlichen Komponenten erforderlich sind. Dabei muss das Titandioxid nicht chemisch rein sein, was die Kosten nur unnötig erhöhen würde, sondern kann beispielsweise metallische, oxidische oder karbidische Verunreinigungen aufweisen. Eine definierte Zusatzkomponente neben dem Titandioxid ist für die erste Reibschicht jedenfalls nicht erforderlich.The Coating is particularly easy to realize because except titanium dioxide no additional components required are. The titanium dioxide does not have to be chemically pure its just unnecessary costs increase would, but may, for example, metallic, oxidic or carbidic Have impurities. A defined additional component next to the titanium dioxide is for In any case, the first friction layer is not required.
Optimal für das Reibverhalten ist ein möglichst hoher Anteil des Titandioxids in der ersten Reibschicht. Gleichwohl kann die erste Reibschicht auch einen wesentlich geringeren Anteil an Titandioxid aufweisen. Solange der Titandioxidanteil mindestens 30% beträgt, weist die Reibkupplung durch das Zusammenwirken mit der zweiten nitrierten, nitrocarburierten oder carbonitrierten Reibschicht immer noch vorteilhafte Reibeigenschaften auf.Optimal for the Frictional behavior is one possible high proportion of titanium dioxide in the first friction layer. nevertheless the first friction layer can also have a much smaller share have on titanium dioxide. As long as the titanium dioxide content at least 30%, has the friction clutch through the interaction with the second nitrided, nitrocarburized or carbonitrided friction layer still advantageous friction properties.
Die Erfindung wird an nachstehenden Ausführungsbeispielen näher erläutert.The Invention will be explained in more detail in the following embodiments.
