Metallische Schaltgabel zum Fuhren und Axialverschieben von metalli schen Schaltmuffen bei GetriebenMetallic shift fork for guiding and axial displacement of metalli shifter sleeves in gearboxes
Die Erfindung betrifft eine metallische Schaltgabel zum Führen und Axialverschieben von metallischen Schaltmuffen bei Getrieben. Die bisher bekannten Schaltgabeln, z. B. fUr die Synchronvorrichtung bei Getrieben, bestehen aus Sondermessing wwdr Stahl mit verchromten Anlaufflächen.The invention relates to a metallic shift fork for guiding and axial displacement of metallic shift sleeves in gearboxes. The previously known shift forks, z. B. for the synchronizing device in gearboxes, consist of special brass wwdr steel with chrome-plated contact surfaces.
Die Nachteile der Schaltgabe!η aus Sondermessing bestehen darin, daß die Gabeln nach der Bearbeitung gerichtet werden mUssen und bei hoher axialer Beanspruchung ein Verschränken der Gabelschenkel möglich ist (geringer Elastizitätsmodul). Die Schaltgabeln aus Stahl sind zwar den Schaltgabeln aus Sondermessing Überlegen, haben aber den Nachteil, daß die Verchromung der Anlaufflächen eine enorme Verteuerung mit sich bringt.The disadvantages of the switching ability! Η made of special brass are that the Forks have to be straightened after machining and, if there is high axial load, the fork legs can be twisted (less Modulus of elasticity). The shift forks made of steel are superior to the shift forks made of special brass, but have the disadvantage that the Chrome plating of the contact surfaces brings with it an enormous increase in price.
Der Erfindung liegt daher die Aufgabe zugrunde, die Nachteile der bekannten Schaltgabelausfuhrungen zu beseitigen bzw. diese und die Schaltmuffe so zu verbessern, daß eine exakte Führung erreicht wird und die Herstellungskosten gesenkt werden können.The invention is therefore based on the object of addressing the disadvantages of the known Eliminate shift fork versions or these and the shift sleeve to improve so that an exact guidance is achieved and the manufacturing costs can be lowered.
Π)«;» ΔιιίηηΚβ vi'itA «rf jnriiinotnemHß gelKst durch einen im Bereich der Anlaufflächen von Schaltgabel und Schaltmuffe auf den einen und/oder anderen der beiden metallischen Grundkörper aufgebrachten Kunststoff -belog. Der Kunststoffbelag ist vorzugsweise durch ein im Querschnitt U-förmiges Kunststoffprofil gebildet. Der Belag ist dabei durch Sicken, Noppen o.dgl. auf den jeweiligen metallischen Grundkörper festgelegt. In einer anderen Ausf Uhrungsform ist der Kunststoffbelag durch eine Kleboder Schweißverbindung auf den jeweiligen metallischen Grundkörper festgelegt.Π) «;» ΔιιίηηΚβ vi'itA «rf jnriiinotnemHß gelKt by a plastic layer applied to one and / or the other of the two metallic base bodies in the area of the contact surfaces of the shift fork and shift sleeve. The plastic covering is preferably formed by a plastic profile with a U-shaped cross section. The covering is by beads, knobs or the like. fixed on the respective metallic base body. In another embodiment, the plastic covering is fixed to the respective metallic base body by means of an adhesive or welded connection.
Der Erfindungsgedanke, der die verschiedensten AusfUhrungsmöghchkeiten zuläßt, ist in einem Ai'sfuhrungsbeispiel anhand der beiliegenden Z*ich -nung näher erläutert. Dabei zeigt :The idea of the invention, the most diverse execution possibilities allows, is explained in more detail in an example with reference to the enclosed drawing. It shows:
einer von der Schaltgabel axial verschiebiichen Schaltmuffe,one of the shift fork axially movable shift sleeve,
gabel undfork and
Die von einem Schaltgestänge 4 axial verschiebliche Schaltgabel 1, greift mit ihren Gabe !schenke in in der Üblichen Weise in die Nut der Schaltmuffe 3 ein, In der dargestellten Ausführungsform ist der vorzugsweise aus Stahl bestehende Grundkörper 1 der Schaltgabel 1,2 mit einsm Kunststoffbelag 2 versehen, welcher im Querschnitt U-förmig ausbildet ist und mit Hilfe von Sicken 2 α rutschsicher auf dem Grundkörper befestigt ist.The shift fork 1, which is axially displaceable by a shift linkage 4, Grasp with your gift! give in the usual way in the groove of the Shift sleeve 3, In the embodiment shown, the base body 1, which is preferably made of steel, is the shift fork 1,2 Einsm plastic covering 2 is provided, which is U-shaped in cross-section and with the help of beads 2 α non-slip on the base body is attached.
Durch diese erfindungsgemäße Ausbildung kann ein Werkstoff mir hohem Elastizitätsmodul veiwendet werden. Die Flächen zum Auf bringen der Kunststoffschicht bzw. des Belages 2 brauchen nicht mehr bearbeitet zu werden. Die Sicken oder eine Klebverbindung sorgen für einen sicheren Sitz des Belages auf dem Giundkörper . Der Kunststoff hat eine hohe Abriebfestigkeit und ist somit fUr hohe axiale Beanspruchung geeignet. Diese SchaltgabelausfUhrung ist in der Herstellung sehr billig und erfüllt in allen Punkten die geforderten Funktionen.This inventive training a material can me high modulus of elasticity can be used. Bring the surfaces up the plastic layer or the covering 2 no longer need to be processed. The beads or an adhesive connection ensure a secure fit of the covering on the base body. The plastic has a high abrasion resistance and is therefore suitable for high axial loads suitable. This SchaltgabelausfUhrung is in production very cheap and fulfills the required functions in all points.
In einem nicht dargestellten Ausfuhrungsbeispiel ist der Belag bzw. die Kunststoffbeschichtung als eine im Querschnitt U-förmige Auskleidung der Nut der Schaltmuffe 3 ausgebildet.In an exemplary embodiment, not shown, the covering or the plastic coating is designed as a lining of the groove of the shift sleeve 3 with a U-shaped cross-section.
