Description

knickt, der an seinem freien Ende ein Handgriffstück 11 trägt. Unterhalb des Gelenkblockes 8 ist an dem Schalthebelteil 10 ein Kröpfungsteil 14 befestigt, in dem der untere Schalthebelteil 13 befestigt ist, dessen unteres Ende unmittelbar in die Schaltstangenköpfe 5 eingreift. Die Zwischenplatte 15 verhindert dabei, daß der Schalthebel 13 durch Schwenken um den Lagerbolzen 7 von einem Schaltstangenkopf 5 in den anderen Schaltstangenkopf 5 oder zurück übergeführt wird, solange nicht der eine Schaltstangenkopf 5 in der Neutrallage der Schaltstange 6 liegt. Die Gummimuffe 9 befindet sich in ihrem spannungslosen Zustand, wenn das untere Ende des Schalthebelteils 13 zwischen den beiden Schaltstangenköpfen 5 liegt.kinks, which carries a handle 11 at its free end. Below the joint block 8 is on the shift lever part 10 is attached a crank part 14 in which the lower shift lever part 13 is attached, its lower end directly into the shift rod heads 5 intervenes. The intermediate plate 15 prevents the shift lever 13 from pivoting around the bearing pin 7 transferred from one shift rod head 5 to the other shift rod head 5 or back as long as the one shift rod head 5 is not in the neutral position of the shift rod 6. The rubber sleeve 9 is in its de-energized state when the lower end of the shift lever part 13 lies between the two shift rod heads 5.

Die Wirkungsweise ist folgende: Zur Wahl der Schaltgasse wird durch Verschwenken des Handgriffstückes 11 um den Lagerbolzen 7 im Sinn der Pfeile α bzw. b auch der untere Schalthebelteil 13 um die Achse des Lagerbolzens 7 geschwenkt und dabei bei einem Verschwenken im Sinn des Pfeiles α in den einen Schaltstangenkopf 5 bzw. bei einem Verschwenken im Sinn des Pfeiles b in den anderen Schaltstangenkopf 5 geführt. Durch Verschwenken des Handgriffstückes 11 um die Längsachse des Schalthebelteiles 10 im Sinne des Pfeiles c oder d wird dieses in der Bohrung des Gelenkstückes 8 verschwenkt. Diese Schwenkbewegung macht das Kröpfungsteil 14 mit und würde entsprechend den unteren Teil 13 des Schalthebels auf einem Kreisbogen führen, wenn nicht bei dieser Verschwenkbewegung durch eine geringfügige zusätzliche Schwenkbewegung um die Achse des Lagerbolzens 7, die sich von selbst durch die Bewegung des Schaltstangenkopfes ergibt, diese Kreisbogenbewegung zu einer geradlinigen Bewegung gestreckt würde. Dadurch wird die jeweils gewählte Schaltstange 6 im Sinn der Pfeile e oder / verschoben.The mode of operation is as follows: To select the shift gate, by pivoting the handle 11 about the bearing pin 7 in the direction of the arrows α or b , the lower shift lever part 13 is also pivoted about the axis of the bearing pin 7 and while pivoting in the direction of the arrow α in one shift rod head 5 or, when pivoting in the direction of arrow b, into the other shift rod head 5. By pivoting the handle piece 11 about the longitudinal axis of the shift lever part 10 in the direction of arrow c or d , this is pivoted in the bore of the joint piece 8. This pivoting movement makes the crank part 14 and would lead accordingly the lower part 13 of the shift lever on a circular arc, if not during this pivoting movement by a slight additional pivoting movement about the axis of the bearing pin 7, which results automatically from the movement of the shift rod head Circular arc motion would be stretched to a rectilinear motion. As a result, the selected shift rod 6 is shifted in the direction of the arrows e and /.

Das direkte Eingreifen des starr mit dem Handgriffstück 11 verbundenen unteren Teiles 13 des Schalthebels in die Schaltstangenköpfe 5 ermöglicht ein feinfühliges Schalten. Das Handgriffstück 11 liegt dabei günstig in der Nähe des Lenkrades 1, und die mit diesem zurückzulegenden Wege sind entsprechend den Schwenkwinkeln um das Gelenkstück 7,8 verhältnismäßig gering, so daß das Handgriffteil 12 des Schalthebels 10,12,13 in keiner Lage desselben den Bewegungsraum des Fahrers beengt.The direct engagement of the rigidly connected to the handle 11 lower part 13 of the Shift lever in the shift rod heads 5 enables sensitive switching. The handle 11 is located cheap in the vicinity of the steering wheel 1, and the paths to be covered with this are corresponding the pivot angles around the joint piece 7, 8 are relatively small, so that the handle part 12 of the shift lever 10, 12, 13 in no position of the same restricts the driver's freedom of movement.
