Description
Eine
gattungsgemäße Gangwähleinrichtung ist

Aus
der
Die
In Sperrstellung des Mittelstempels sind die Ausnehmungen versetzt zu den Sperrkugeln. In der Freigabestellung können die Sperrkugeln von dem schrägen Abschlussflansch des Sperrbolzens in die Ausnehmungen gedrückt werden, so dass sie geringfügig weiter an den schrägen Anschlagflächen entlang wandern können, was zu einer geringfügigen Axialbeweglichkeit des Sperrbolzens führt. Nachteilig bei dieser bekannten Vorrichtung ist der nur sehr geringe Bewegungsspielraum des Sperrbolzens.In Locked position of the center punch the recesses are offset to the locking balls. In the release position, the locking balls from the sloping end flange of the locking pin are pressed into the recesses so that they continue slightly further on the sloping stop surfaces can walk along resulting in a slight axial mobility of the locking bolt leads. A disadvantage of this known device is only very small Movement travel of the locking bolt.

Aufgabenstellungtask
Der Erfindung liegt die Aufgabe zugrunde, gattungsgemäße Gangwähleinrichtungen so weiterzubilden, dass die vorstehend genannten Probleme vermieden werden und dass insbesondere eine Bauraum sparende, leicht austauschbare Einheit geschaffen wird.Of the Invention is based on the object, generic Gangwähleinrichtungen educate so that the above problems avoided and that in particular a space-saving, easily replaceable Unity is created.
Diese Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Patentanspruchs 1.This problem is solved by the kenn characterizing features of claim 1.
Besonders vorteilhafte Weiterbildungen der Erfindung, insbesondere im Hinblick auf deren Konstruktion, sind Gegenstand der Unteransprüche.Especially advantageous developments of the invention, in particular with regard to on the construction, are the subject of the dependent claims.
Erfindungsgemäß ist also vorgesehen, dass das Sperrglied als eine zu dem Sperrbolzen koaxiale, den Sperrbolzen und dessen als Führungshülse ausgebildetes Führungselement glockenartig umgreifende Zughülse ausgebildet ist, gegen deren Boden sich der Sperrbolzen über eine Druckfeder abstützt. Dadurch ist für eine erfindungsgemäße Gangsperre eine besonders kompakte Bauweise möglichAccording to the invention is thus provided that the locking member as a coaxial to the locking pin, the Locking pin and its trained as a guide sleeve guide element bell-like pulling sleeve is formed, against the bottom of the locking pin on a Compressed spring supported. This is for a passage barrier according to the invention a particularly compact design possible
Besonders vorteilhaft ist die gemäß Anspruch 2 vorgeschlagene Unterbringung des Sperrbolzens in einer Hohlschraube, die ihrerseits in das Getriebegehäuse einsetzbar ist.Especially advantageous is that according to claim 2 proposed accommodation of the locking bolt in a hollow screw, which in turn can be used in the transmission housing.
Ein solches System kann darüber hinaus ohne großen Konstruktionsaufwand in bereits in Serie befindliche Getriebekonzepte eingebunden werden. Der Aufbau aus insgesamt nur wenigen Einzelbauteilen gewährleistet außerdem eine hohe Betriebssicherheit.One such system can about it also without big ones Design effort in already in series gear concepts be involved. The structure of a total of only a few individual components guaranteed Furthermore a high level of operational safety.
