Abstract
Description
Die Erfindung betrifft eine Schalteinrichtung eines
Schaltgetriebes nach dem Oberbegriff des Patentanspruches 1 – bekannt
durch die
Bei dem durch die
Es ist Aufgabe der vorliegenden Erfindung, den Schaltvorgang der eingangs genannten Schalteinrichtung dahingehend zu verbessern, dass ein auf die Schiebemuffe wirkendes Kippmoment vermieden oder zumindest in seiner Wirkung vermindert wird.It is an object of the present invention Switching operation of the switching device mentioned above to improve that a tilting moment acting on the sliding sleeve avoided or at least reduced in its effect.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Patentanspruches 1. In die Ringnut der Schiebemuffe ist eine ringförmige Gleitvorrichtung eingesetzt, die über zwei diametral angeordnete Zapfen im Getriebegehäuse fixiert, jedoch in axialer Richtung der Schiebemuffe gleitend gelagert ist. Die erfindungsgemäße Konstruktion hat den Vorteil, dass die resultierende Schaltkraft zur Verschiebung der Schiebemuffe zentrisch an der der Schiebemuffe und damit ohne Erzeugung eines Kippmomentes angreift. Dies wird dadurch erreicht, dass die gemeinsame Achse der beiden sich diametral gegenüberliegenden Zapfen unabhängig von der Stellung der Schaltschwinge stets durch den Mittelpunkt der Schiebemuffe verläuft. Darüber hinaus ergibt sich durch die ringförmige Ausbildung der Gleitvorrichtung eine über den Umfang verteilte Anlage und somit eine gleichmäßige Einleitung der Schaltkraft in die Schiebemuffe. Dies führt auch zu einer geringeren Flächenpressung zwischen Gleitvorrichtung und Schiebemuffe.This task is solved by the features of claim 1. In the annular groove of the sliding sleeve is an annular one Sliding device used, which has two diametrically arranged pins in the gearbox fixed, but slidably mounted in the axial direction of the sliding sleeve is. The construction according to the invention has the advantage of shifting the resulting shifting force the sliding sleeve centrally on the sliding sleeve and thus without Generation of a tilting moment attacks. This is achieved that the common axis of the two is diametrically opposite Cones independently from the position of the rocker arm always through the center the sliding sleeve runs. About that also results from the annular design of the sliding device one over the scope of the distributed system and thus a uniform introduction the switching force in the sliding sleeve. This also leads to a lower one surface pressure between sliding device and sliding sleeve.
Nach einer vorteilhaften Ausgestaltung der Erfindung sind die Zapfen mit einem vorzugsweise länglich in Form einer Passfeder ausgebildeten Gleitstück verbunden, welches in einer axial verlaufenden Nut des Getriebegehäuses geführt ist. Damit wird einerseits ein Kippen der ringförmigen Gleitvorrichtung um die gemeinsame Achse der Zapfen verhindert und andererseits eine lineare Gleitbahn – parallel zur Rotationsachse der Schiebemuffe – ermöglicht.According to an advantageous embodiment of the invention, the pins are preferably elongated in Form of a feather key slider connected, which in a axially extending groove of the gear housing is guided. So on the one hand a tilting of the annular Prevents sliding device around the common axis of the pin and on the other hand, a linear slideway - parallel to the axis of rotation the sliding sleeve - enables.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist die als Schaltgabel ausgebildete Schaltschwinge an ihren Enden Langlöcher auf, welche die Zapfen der Gleitvorrichtung aufnehmen. Durch die Langlöcher werden die abweichenden Bewegungsbahnen von Schaltschwinge (kreisförmig) und Zapfen sowie Gleitstück (linear) kompensiert. Die Zapfen können sich somit innerhalb der Langlöcher quer zur Schwenkbewegung frei bewegen.After another advantageous one Embodiment of the invention has that designed as a shift fork Switch rocker arm at its ends on elongated holes, which the pin pick up the glider. Through the elongated holes are the different ones Trajectories of the swing arm (circular) and pin as well as slide (linear) compensated. The cones can thus within the elongated holes move freely across the swivel movement.
Nach weiteren vorteilhaften Ausgestaltungen der Erfindung ist die Gleitvorrichtung entweder als geschlossener Ring ausgebildet oder aus einzelnen Ringsegmenten zusammengesetzt. Bei einem geschlossenen Ring ergibt sich eine gleichmäßige Anlage und Schaltkrafteinleitung sowie eine Fixierung und Ausrichtung der Zapfen zueinander. Bei einer Segmentbauweise ergeben sich beim Einbau bezüglich der Toleranzen Vorteile, und zwar im Hinblick auf die Lage der gemeinsamen Achse der beiden Zapfen.According to further advantageous embodiments of the Invention is the sliding device either as a closed ring trained or composed of individual ring segments. at a closed ring results in an even contact and switching force introduction as well as a fixation and alignment of the Tenon to each other. In the case of a segmental construction, the result is installation in terms of the tolerances advantages, in terms of the location of the common Axis of the two pins.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.
