Description
Synchronkegel.Synchro cone.
Die Erfindung bezieht sich auf Synchronkegel für Wechselgetriebe, insbesondere in Straßenfahrzeugen.The invention relates to synchronizer cones for change gears, in particular in road vehicles.
In Tourenfahrzeugen oder Fahrzeugen mit geringer Zuladung werdenSynchronkegel verwendet, die aus unterschiedlichen Werkstoffen bestehen, z.B. aus Bronze, aus Leichtmetall, insbesondereaus Sintermetall.In touring vehicles or vehicles with low payloads, synchronizer cones are used that consist of different Materials, e.g. bronze, light metal, especially sintered metal.
Bei Lastkraftwagen entwickeln die Schaltgetriebe wegen ihrer Abmessungen erhebliche Trägheitskräfte, die hohe Synchronisationsmomente zur Folge haben.In trucks, the manual transmissions develop considerable inertial forces due to their dimensions, the high synchronization torques have as a consequence.
Wenn darüber hinaus Lastwagengetriebe ein Zusatzgetriebe besitzen, mit dem die Zahl der Schaltkombinationen verdoppelt oder verdreifacht wird, läßt die Synchronisation dieser Zusatzgetriebe die Belastungen, denen die Synchronkegel ausgesetzt sind, noch zunehmen.If, in addition, truck transmissions have an additional transmission that doubles the number of shift combinations or tripled, the synchronization of these additional gears eliminates the loads to which the synchronizer cones are exposed are still increasing.
Der Erfindung liegt die Aufgabe zugrunde, Synchronkegel zu entwickeln, die diesen Beanspruchungen gewachsen sind, wobei ausser hoher Lebensdauer und gutem Wirkungsgrad noch eine wirtschaftliche Herstellung durch Formung ohne zusätzlicheThe invention is based on the object of developing synchronizing cones that can cope with these stresses, with In addition to a long service life and good efficiency, it can also be manufactured economically through molding without additional

Nacharbeit gegeben sein soll; gleichzeitig soll ein für die Arbeitsweise wichtiger Nutzen hinsichtlich des Gewichts erzielt werden.Rework should be given; at the same time, an important benefit in terms of weight is to be achieved for the working method will.
Der erfindungsgemäße Synchronkegel ist im wesentlichen dadurch gekennzeichnet, daß er aus einem Grundmaterial hergestellt ist, das aus einem glasfaserverstärkten Polyimidharz besteht, wie es beispielsweise von der Societe Rhone-Poulenc unter der Bezeichnung "KINEL" produziert wird.The synchronizing cone according to the invention is essentially characterized in that it is made from a base material is made of a glass fiber reinforced polyimide resin exists, for example from the Societe Rhone-Poulenc is produced under the name "KINEL".
Es hat sich gezeigt, daß die durch Formung erzielbaren mechanischen Eigenschaften eines solchen Materials so günstig sind, daß man ein einheitliches Werkstück ohne Metalleinlage durch Spritzgießen oder Formpressen herstellen kann, das allen in Synchronisiereinrichtungen der Getriebe von Schwerlastwagen auftretenden Belastungen gewachsen ist.It has been shown that the mechanical Properties of such a material are so favorable that you can get a uniform workpiece without a metal insert can manufacture by injection molding or compression molding, all in synchronizers of the gearboxes of heavy goods vehicles is able to cope with occurring loads.
Es hat sich ferner herausgestellt, daß das Material nur geringem Verschleiß unterliegt und gute Formbeständigkeit unter Belastung sowie Warmformbeständigkeit in dem geforderten Maße aufweist.It has also been found that the material is subject to little wear and tear and has good dimensional stability Load and heat resistance to the required extent.
Ferner liegt eine Art Selbstschmierung vor, durch die Beschädigungen durch örtlichen Heißlauf vermieden werden, womit noch ein günstiger Dauerreibungskoeffizient verbunden ist, so daß lange Lebensdauer und Wirtschaftlichkeit ebenfalls gegeben sind.Furthermore, there is a kind of self-lubrication due to the damage can be avoided by local overheating, which is also associated with a favorable coefficient of permanent friction, so that a long service life and economy are also given.
Gute Ergebnisse wurden mit den erwähnten Werkstoffen "KINEL" 5504 und 5515 erzielt.Good results have been achieved with the materials "KINEL" 5504 and 5515 mentioned.
Natürlich kann ein derartiger Aufbau bei allen Arten von Synchronisiereinrichtung verwendet werden.Such a structure can of course be used with all types of synchronizing device be used.
Eine mögliche Ausführungsform eines Synchronkegels gemäßA possible embodiment of a synchronizing cone according to
909843/1008909843/1008
der Erfindung wird nachstehend anhand der Zeichnung beschrieben; die einzige Figur stellt einen Axialschnitt durch eine Gruppe aus zwei Kegeln 1 und 2 dar, die in einer Doppelsynchronisiereinrichtung verwendet v/erden sollen und die in an sich bekannter Weise durch sechs kleine Stützen verbunden werden, im vorliegenden Falle drei Stützen 3 und drei Stützen 4, die so ausgebildet sind, daß sie mit einem Zwischenelement der Synchronisiereinrichtung in Sperrfunktion und zum Verriegeln der eingelegten Gänge zusammenwirken, welche Funktionen mit Hilfe der Synchronisiereinrichtung ausgeübt werden.the invention is described below with reference to the drawing; the single figure represents an axial section through a group of two cones 1 and 2, which are in a double synchronizer should be used and connected in a known manner by six small supports are, in the present case three supports 3 and three supports 4, which are designed so that they are with an intermediate element the synchronizing device in locking function and for locking the engaged gears cooperate, which Functions are exercised with the help of the synchronizer.
An die Kegel 1, 2 sind Löcher 5 angeformt, in die die Enden der Stützen 3 und 4 eingreifen; diese Stützen sind mit als axiale Abstützung dienenden Schultern 6 ausgestattet, und die Enden der Kegel werden, wie in der Zeichnung angedeutet, gespreizt, damit· die Kegel durch Klemmwirkung zu einem unbeweglichen Bauelement werden.On the cones 1, 2 holes 5 are formed into which the ends of the supports 3 and 4 engage; these supports are with as axial support serving shoulders 6 equipped, and the ends of the cones are, as indicated in the drawing, Spread apart, so that · the cones become an immovable structural element due to the clamping effect.
Bei der Formung der Kegel können an der wirksamen Fläche Rinnen 7 ausgespart und/oder kann ein übliches Netz von Ölablaufnuten ausgebildet sein.When the cones are formed, grooves 7 can be recessed on the effective surface and / or a conventional network of oil drainage grooves can be used be trained.
