Description
Die Erfindung betrifft einen Schwenkbolzen einer an dem Schwenkbolzen um eine Schwenkachse schwenkbaren Schaltschwinge, wobei der Schwenkbolzen aus Stahl ist.The invention relates to a pivot pin on the swivel pin, swing arm pivotable about a swivel axis, the pivot pin is made of steel.
Derartige Schwenkbolzen sind in dem
vom Springer-Verlag 1996 in der 3. Auflage veröffentlichten Fachbuch „Zahnradgetriebe" des Autors Looman, J.
auf den Seiten 149 bzw. 255 in der
Die Schwenkbolzen sind in den verschiedensten Ausführungen gestaltet. Sie sind zumeist rotationssymmetrisch zu der Schwenkachse der Schaltschwinge ausgebildet. Es gibt Ausführungen, die eine zylindrische Außenfläche für die Aufnahme des Lagerauges oder eine Sitzfläche für das Wälzlager der Schwingenlagerung aufweisen. Die Schwenkbolzen sind beispielsweise durch einen Preßsitz in einer Bohrung der Umgebungskonstruktion, mittels einer Schweißverbindung, mittels einer Bördelverbindung oder durch eine Schraubverbindung am Gehäuse oder relativ zum Gehäuse des Getriebes befestigt. Mittels einer Schraubverbindung befestigte Schwenkbolzen weisen entweder ein Innengewinde oder ein Außengewinde auf. In das Innengewinde greift eine zu dem Schwenkbolzen separate Schraube ein. Mit dem Außengewinde ist der Schwenkbolzen in ein Innengewinde der Umgebungskonstruktion eingeschraubt. Schwenkbolzen sind zum Anziehen der Schraubverbindung wahlweise mit Mehrkanten, vorzugsweise mit Sechskanten, versehen.The pivot pins are in a wide variety versions designed. They are usually rotationally symmetrical to the swivel axis the shift arm. There are designs that are cylindrical Outside surface for receiving the Bearing eyes or a seat for the roller bearing the swing arm bearing. The pivot bolts are, for example through a press fit in a hole in the surrounding structure, using a welded connection, by means of a flare connection or by a screw connection on the housing or relative to the housing of the Gearbox attached. Fixed with a screw connection Swivel pins have either an internal thread or an external thread on. A separate gripping pin engages in the internal thread Screw in. With the external thread is the swivel pin in an internal thread of the surrounding construction screwed. Swivel bolts are used to tighten the screw connection optionally with polygons, preferably with hexagons.
Die Herstellung von derartigen Schwingenlagerungen ist relativ aufwändig, da die fertigen Umrisse der Schwenkbolzen in den vorgenannten Ausführungsformen teilweise recht aufwändig durch spanabhebende Bearbeitung hergestellt oder nachbearbeitet sind. Außerdem ist die Schwingenlagerung mit Wälzlagerungen relativ aufwändig zu montieren.The manufacture of such swing arm bearings is relatively complex, since the finished outline of the pivot pin in the aforementioned embodiments sometimes quite complex manufactured or reworked by machining are. Moreover is the swing arm bearing with roller bearings relatively complex to assemble.
Zu dem Zeitpunkt, an dem die Erfindung gemacht wurde, bestand die Aufgabe, einen Schwenkbolzen in den vorgenannten Ausführungsformen für eine insbesondere in der Großserien- und Massenproduktion kostengünstig herzustellende Schwingenlagerung zu schaffen.At the time the invention was made, the task was a pivot pin in the aforementioned embodiments for one especially in large series and mass production inexpensively to create swing arm bearings to be manufactured.
Diese Aufgabe ist nach dem kennzeichnenden Teil des Anspruchs 1 dadurch gelöst, dass der Schwenkbolzen einen mittels Kaltumformen fertiggestellten Umriß aufweist. Ein erfindungsgemäßer Schwenkbolzen mit den eingangs beschriebenen Merkmalen bedarf keiner spanabhebenden Bearbeitung. Die gesamte Außenkontur und bei Hohlteilen auch die Innenkontur des Bolzens, einschließlich wahlweise der Sitzfläche für das Wälzlager, des Sechskantes, des Gewindes und die Sitzfläche für den Preßsitz (beispielsweise mit einem Rändel, mit Rippen oder mit einer Kerbverzahnung) sind durch kaltumformende Fertigungsverfahren wie Ziehen aus Blech, Pressen und Fließpressen aus massiven Rohlingen, Rollieren und Prägen hergestellt. Die Herstellung derartiger Bolzen ist materialsparend, da durch die eingesetzten Technologien kein oder kaum Abfallmaterial anfällt. Die gemäß einer Ausgestaltung der Erfindung hohlen Bolzen weisen ein geringes Gewicht auf und sind außerdem wahlweise für die Aufnahme von Meßfühlern oder ähnlichem bzw. als Durchführung für weitere Elemente des Getriebes geeignet.This task is after the characteristic Part of claim 1 solved by that the swivel pin is finished by means of cold forming Outline. An inventive pivot pin with the features described at the beginning, no machining is required Processing. The entire outer contour and for hollow parts also the inner contour of the bolt, including optional the seat for the Roller bearing, of the hexagon, the thread and the seat for the press fit (for example with a knurled, with ribs or with serration) are due to cold forming Manufacturing processes such as drawing from sheet metal, pressing and extrusion made from solid blanks, burnishing and embossing. The production such bolt is material-saving, because of the used Technologies with no or hardly any waste material. According to one Embodiment of the invention hollow bolts are light in weight on and are also optionally for the inclusion of sensors or the like or as implementation for further Suitable elements of the transmission.
Als Werkstoffe sind alle kaltumformbaren Stahlwerkstoffe, wie Einsatzstähle der Materialbezeichnung 16 MnCr5, verwendbar. Für die Herstellung von Fließpreßteilen sind z.B. Rohlinge warmgeformter Drähte eingesetzt. Die Schwenkbolzen sind nach dem Kaltverformen wärmebehandelt, vorzugsweise einsatzgehärtet und angelassen und weisen bevorzugt Oberflächenhärten von 650-800 Härtegraden, gemessen nach dem Vickers-Verfahren HV10 auf.All cold-formable steel materials are like case hardening steels the material designation 16 MnCr5, can be used. For the production of extruded parts are e.g. Blanks of thermoformed wires are used. The pivot bolts are heat treated after cold working, preferably case hardened and tempered and preferably have surface hardnesses of 650-800 degrees of hardness, measured according to the Vickers method HV10.
Die Laufrille oder Laufbahn in jeder geeigneten Ausführung, z.B. mit Schmiegung für den Einsatz eines Schrägkugellagers, ist durch das Kaltverformen an der Oberfläche, insbesondere durch Rollieren so geglättet, dass ein Schleifen und/oder Finishen entfällt. Weiter ausgestaltet ist die Erfindung mit einem Schwenkbolzen, bei dem die Härte zumindest an der Oberfläche der Laufrille durch Rollieren fertig eingestellt ist. Dass durch das Kaltverformen verfestigte Material weist an der Laufbahn eine ausreichende Härte für den Wälzkontakt mit den Wälzkörpern des Wälzlagers auf. Alternativ sind nicht gehärtete Schwenkbolzen vorgesehen, an denen sich weiterhin ein Laufring eines Wälzlagers zur Lagerung einer Schaltschwinge abstützt.The raceway or track in any suitable design, for example with osculation for the use of an angular contact ball bearing, is smoothed by the cold shaping on the surface, in particular by rolling, so that grinding and / or finishing is not necessary. The invention is further developed with a pivot pin, in which the hardness is set at least on the surface of the raceway by rolling. The fact that the material is hardened by the cold-forming process is sufficient for the career de Hardness for rolling contact with the rolling elements of the rolling bearing. Alternatively, non-hardened pivot pins are provided, on which a race of a rolling bearing for supporting a shift rocker is supported.
