Bei einem Getriebe, bei welchem das Einlegen der Gänge mittels Hilfskraft erfolgt, ist es bekannt, die Stellung des Schalthebels gegenüber einem Schalthebelgehäuse mit tels im Schalthebelgehäuse eingebauter magnetempfindli cher Sensoren und am Schalthebel befestigter Magnete kon takt- und berührungslos abzutasten (EP-PS 0 075 693).In the case of a transmission in which the gears are engaged done by assistant, it is known the position the shift lever with a shift lever housing Magnet-sensitive built into the gear lever housing cher sensors and magnets attached to the gear lever con tactile and contactless to scan (EP-PS 0 075 693).
Bei einem anderen dem Stand der Technik bekannten Schalt kontaktgehäuse sind die Schaltkontakte im wesentlichen symmetrisch zur Mittelachse des Schaltkontaktgehäuses an geordnet. Diese Anordnung erfordert einen relativ großen Bauraum. So betrug der Durchmesser des Schaltkontaktge häuses ca. 100 mm. Durch eine andere geeignetere Anord nung soll der Bauraum des Schaltkontaktgehäuses ver kleinert werden, denn dadurch entsteht eine kostengünsti gere - da kleinere Baueinheit - Lösung. In another switching known from the prior art Contact housings are essentially the switch contacts symmetrical to the central axis of the switch contact housing orderly. This arrangement requires a relatively large one Installation space. So the diameter of the Schaltkontaktge was about 100 mm. By another more appropriate arrangement The installation space of the switch contact housing should ver be reduced in size because this creates a cost-effective ger - because smaller unit - solution.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schaltwelle zwei Schaltfinger besitzt, die unter ei nem bestimmten Winkel zueinander stehen und auf der Achse der Schaltwelle durch einen Abstand beabstandet sind und die Schaltfinger beim Schalten eines Ganges diametral bzw. punktsymmetrisch zu der in der Mitte liegenden Schaltbahn des Rückwärtsganges angeordnete Schaltkontakte öffnen oder schließen. Vorzugsweise werden als Schaltkon takte Reedschalter oder Hall-Elemente verwendet.This object is achieved in that the selector shaft has two shift fingers, which are under egg stand at a certain angle to each other and on the axis the shift shaft are spaced apart by a distance and the shift fingers when shifting a gear diametrically or point symmetrical to the one in the middle Switching path of the reverse gear arranged switching contacts open or close. Preferably, as a switching con clocked reed switches or Hall elements are used.
Die erfindungsgemäße Vorrichtung hat den wesentlichen Vorteil, daß der Bauraum für sie verkleinert werden kann, was zu einer einfacheren Lösung führt. Der Durchmesser des Schaltkontaktgehäuses konnte auf 60 gegenüber 100 mm verkleinert werden.The device according to the invention has the essential Advantage that the space for them can be reduced, which leads to an easier solution. The diameter of the switch contact housing could be 60 compared to 100 mm be made smaller.
