Abstract
Description
Die Schaltwelle 4 ist in nicht dargestellter Weise mit einem im Inneren des Kraftfahrzeuges angeordnetem Schalthabel verbunden. Auf der Schaltwelle 4 ist ein radial abragender Schaltfinger 6 über eine mit dem Schaltfinger 6 einteilig ausgebildete Hülse 8 befestigt.The shift shaft 4 is in a manner not shown with an inside of the motor vehicle arranged Shift cable connected. On the Shift shaft 4 is a radially protruding shift finger 6 over one with the shift finger 6 one-piece sleeve 8 attached.
Im Bereich des Schaltfingers 6 sind drei Schaltelemente in Form von Schaltschienen 10, 12, 14 angeordnet, die an quer zur Schaltwelle 4 verschieblichen, im Gehäuse 2 geführten Schaltstangen 16, 18, 20 befestigt sind. Die Schaltstangen 16, 18, 20 tragen in bekannter Weise Schaltgabeln, mit denen die einzelnen Getriebegänge schaltbar sind. Im gezeigten Beispiel sind mit der Schaltstange 16 der 1. und II. Getriebegang, mit der Schaltstange 18 der III. und IV. sowie mit der Schaltstange 20 der V. und Rückwärtsgang schaltbar. In the area of the shift finger 6 are three switching elements in the form of Shift rails 10, 12, 14 arranged, which are displaceable transversely to the shift shaft 4, Shift rods 16, 18, 20 guided in housing 2 are fastened. The shift rods 16, 18, 20 wear shift forks in a known manner, with which the individual transmission gears are switchable. In the example shown, the 1st and 2nd Gear, with the shift rod 18 of the III. and IV. as well as with the shift rod 20 the V. and reverse gear switchable.
Die Schaltschienen 10, 12, 14 sind mit Schaltgassen bildenden Ausnehmungen 22,24, 26 versehen, in die der Schaltfinger 6 durch entsprechendes axiales Verschieben der Schaltwelle 4 eingreifen kann. Wenn die Ausnehmungen 22, 24, 26 in einer zur Verschieberichtung des Schaltfingers 6 ausgerichteten Linie liegen, befindet sich das Wechselgetriebe in der Neutralstellung; d. h., daß kein Gang eingelegt ist. The shift rails 10, 12, 14 have recesses that form shift gates 22,24, 26 provided, in which the shift finger 6 by appropriate axial displacement the shift shaft 4 can intervene. If the recesses 22, 24, 26 in a to Shift direction of the shift finger 6 aligned line is located the gearbox in neutral; d. that is, no gear is engaged.
Nach dem Vorwählen der gewünschten Schaltgasse, beispielsweise für den V. - Rückwärts - Gang (entsprechend F i g. 1-4), wobei die Schaltwelle 4 axial derart verschoben ist, daß der Schaltfinger 6 in die Ausnehmungen 26 der Schaltschiene 14 eingreift, können durch Verdrehen der Schaltwelle 4 bzw. durch Verschwenken des Schaltfingers 6 aus der Neutralstellung N in entgegengesetzte Richtungen der vorgewählten Gänge R (Rückwärtsgang) und V. geschaltet werden (siehe F i g. 3). After preselecting the desired shift gate, for example for the fifth reverse gear (corresponding to FIGS. 1-4), with the shift shaft 4 being axially is shifted such that the shift finger 6 into the recesses 26 of the shift rail 14 engages, can by rotating the selector shaft 4 or by pivoting the Shift finger 6 from the neutral position N in opposite directions of the preselected Gears R (reverse gear) and V. are shifted (see Fig. 3).
Am Schaltfinger 6 sind zwei radial abragende Sperrnocken 28, 30 ausgebildet, die bei vertikaler Lage des Schaltfingers 6 etwa horizontal ausgerichtet sind. Two radially protruding locking cams 28, 30 are formed on the shift finger 6, which are aligned approximately horizontally when the shift finger 6 is in a vertical position.
Die Sperrnocken 28, 30 liegen in einer Ebene oberhalb der Ausnehmungen 22, 24, 26 und wirken mit bis in die Ebene der Sperrnocken 28, 30 verlängerten, gabelartigen Wandteilen 22a, 24a, 26a zusammen. Der Außenumfang der Sperrnocken 28, 30 ist kreissymmetrisch ausgebildet und wird von den ebenfalls entsprechend gekrümmten Wandteilen 22a, 24a, 26a unter Belassung eines geringen Spieles umfaßt Dementsprechend bilden die Sperrnocken 28, 30 zunächst eine Fixierung der Schaltschienen 10, 12, 14 in deren Neutralstellung. Die Breite der Sperrnocken 28,30 ist so ausgelegt, daß unter Berücksichtigung des Vorwählweges bzw. der axialen Verschiebbarkeit der Schaltwelle 4 eine jede Schaltschiene 10, 12, 14 fixiert ist In die Sperrnocken 28,30 ist je eine Schlitzführung 32, 34 eingefräst, deren Breite geringfügig größer als die Stärke einer Schaltschiene ist. Die Schlitzführungen liegen in einer gemeinsamen Schwenkebene mit dem Schaltfinger 6. Beim Vorwählen beispielsweise der Schaltgasse R - V. liegen somit der Schaltfinger 6, die Schlitzführungen 32, 34 und die Wandteile 26a der Schaltschiene 14 in einer gemeinsamen Ebene, so daß die Schaltschiene 14 geschaltet werden kann. Dabei gleiten die Wandteile 26a abwechselnd in die Schlitzführungen 32 oder 34 des Sperrnockens 28 oder 30 hinein (F i g. 3). Die Tiefe der Schlitzführungen 32,34 ist derart ausgelegt, daß deren Böden 32a, 34a im Zusammenwirken mit den Wandteilen 22a, 24a, 26a Endanschläge für die Schaltschienen 10, 12, 14 bzw. für die einzelnen Gänge bilden.The locking cams 28, 30 lie in a plane above the recesses 22, 24, 26 and act with extended into the plane of the locking cams 28, 30, fork-like wall parts 22a, 24a, 26a together. The outer circumference of the locking cams 28, 30 is circularly symmetrical and is also correspondingly comprises curved wall parts 22a, 24a, 26a leaving a small amount of play Accordingly, the locking cams 28, 30 initially form a fixation of the shift rails 10, 12, 14 in their neutral position. The width of the locking cams 28,30 is designed so that taking into account the preselection path or the axial displaceability of the Shift shaft 4 each shift rail 10, 12, 14 is fixed in the locking cam 28, 30 each has a slot guide 32, 34 milled in, the width of which is slightly larger than the strength of a shift rail. The slot guides are in a common Swivel plane with the shift finger 6. When preselecting, for example, the shift gate R - V. the shift finger 6, the slot guides 32, 34 and the wall parts are thus located 26a of the shift rail 14 in a common plane, so that the shift rail 14 can be switched. The wall parts 26a slide alternately into the slot guides 32 or 34 of the locking cam 28 or 30 in (Fig. 3). The depth of the slot guides 32,34 is designed in such a way that their bottoms 32a, 34a interact with the wall parts 22a, 24a, 26a End stops for the shift rails 10, 12, 14 or for the individual Form corridors.
Ein Schalten ist nur bei einer exakten Vorwahl möglich, weil nur dann die Schlitzführungen 32, 34 der Sperrnocken 28,30 mit der entsprechenden Schaltschiene in einer Ebene liegen. Bei einer unexakten Vorwahl überdecken sich die Schlitzführungen 32, 34 mit keiner Schaltschiene, wodurch sich die Schaltvorrichtung in sich sperrt. Switching is only possible with an exact preselection, because only then the slot guides 32, 34 of the locking cams 28,30 with the corresponding shift rail lie in one plane. If the preselection is inexact, the slot guides overlap 32, 34 with no shift rail, whereby the switching device locks itself.
Diametral gegenüber dem Schaltfinger 6 sind an der Hülse 8 axial verlaufende Rastzähne 36 angeformt, die zusammen mit einem über eine Feder 38 im Gehäuse 2 federnd abgestützten Stift 40 eine Arretierung für die Neutralstellung des Schaltfingers 6 bilden. Diametrically opposite the shift finger 6 are axially on the sleeve 8 extending latching teeth 36 formed, which together with a spring 38 in the Housing 2 resiliently supported pin 40 a lock for the neutral position of the shift finger 6 form.
