Description

Schaltsperren sind bei Getrieben von Fahrzeugmotoren bekannt. Sie bestehen im wesentlichen aus einem kulissenartigen Teil, der Rasten aufweist. In diese Rasten schnappt ein Sperrhebel ein und legt dadurch jeweils eine Stellung für einen Gang fest. Bei bekannten Ausführungen wird die Sperre beim Auskuppeln durch eine Verbindung mit der Betätigungsvorrichtung für die Kupplung vollständig aufgehoben.Shift locks are known in transmissions of vehicle engines. she consist essentially of a link-like part that has notches. In A locking lever snaps into these notches and thereby sets a position in each case for a gear fixed. In known designs, the lock is released when the clutch is disengaged by a connection with the actuator for the clutch completely canceled.

Der Erfindungsgegenstand bezweckt eine Vervollkommnung derartiger Schaltsperren dadurch, daß der Sperrhebel, der in die Rasten des. kulissenartigen Teils einrastet, beim Auskuppeln begrenzt gelüftet wird. Das begrenzte Lüften des Sperrhebels erfolgt durch einen Gelenkhebel, der einerseits eine Fläche zum Lüften des Sperrhebels trägt und andererseits auf einer festen oder verstellbaren Fläche zur Anlage kommt. Durch Abstimmung der Lage dieser beiden Flächen wird der Gelenkhebel durch die Hülle des die Kupplung betätigenden Kabelzuges so bewegt, daß ein begrenztes Lüften der Schaltsperre eintritt. Dies ist vorteilhaft, da der nachfolgende Schaltvorgang erleichtert wird und sofort nach dem Schalten eine Verriegelung des Ganges vorhanden ist, wenn auch mit herabgesetzter Sperrkraft.The object of the invention aims to perfect such Shift locks in that the locking lever, which is in the notches of the Partly engages, when the clutch is disengaged, there is limited ventilation. The limited ventilation of the The locking lever is carried out by an articulated lever, which on the one hand has a surface for ventilation of the locking lever and on the other hand on a fixed or adjustable surface comes to the plant. By coordinating the position of these two surfaces, the articulated lever moved through the sheath of the clutch actuating cable so that a limited Release of the lockout occurs. This is advantageous as the subsequent switching process is made easier and the gear is locked immediately after switching is, albeit with a reduced locking force.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in zwei Stellungen dargestellt.The drawing shows an embodiment of the subject matter of the invention shown in two positions.

Fig. I zeigt den Sperrhebel in der volleingerasteten Stellung; Fig. 2 zeigt den Sperrhebel in der halbangehobenen Stellung.Fig. I shows the locking lever in the fully engaged position; Fig. 2 shows the locking lever in the half-raised position.

Ein kulissenartiger Teil I ist mit Rasten 2 versehen, in welche ein spitzer Teil eines Sperrhebels 3 einrastet. Durch eine Zugfeder 4 wird der Sperrhebel 3 in die Rast gezogen. Auf einen Gelenkhebel 5 drückt die Hülle eines Kabelzuges 6. Der Gelenkhebel 5 schwenkt bei Betätigung der Kupplung um den Punkt 7 und ist mit einer geraden Fläche 8 versehen, auf der sich ein nasenartiger Teil 3a des Sperrhebels 3 abstützt.A backdrop-like part I is provided with notches 2, in which a pointed part of a locking lever 3 engages. A tension spring 4 is the locking lever 3 pulled into rest. The casing of a cable pull presses on an articulated lever 5 6. When the clutch is actuated, the articulated lever 5 pivots around point 7 and is provided with a straight surface 8 on which a nose-like part 3a of the locking lever 3 supports.

Bei der in Fig. 2 dargestellten Stellung hat die Hülle des Kabelzuges 6 auf den Gelenkhebel 5 einen Druck ausgeübt. Dieser schwenkt um den Punkt 7 bis zum Anschlag einer Fläche 9 an eine feste oder verstellbare Fläche Io. Durch die Drehung des Gelenkhebels 5 und die Bewegung des Sperrhebels 3 wird dieser teilweise angehoben. In dieser Stellung ist der kulissenartige Teil noch leicht von dem Sperrhebel 3 gesperrt, doch das Schalten ist sehr erleichtert, da die Feder 4 bereits gespannt ist. Durch Verstellen der Fläche Io kann das Anheben des Sperrhebels 5 verändert werden.In the position shown in Fig. 2, the sheath of the cable pull 6 exerted a pressure on the articulated lever 5. This swivels around point 7 to for stopping a surface 9 on a fixed or adjustable surface Io. Through the Rotation of the articulated lever 5 and the movement of the locking lever 3 becomes part of this raised. In this position, the link-like part is still slightly away from the locking lever 3 locked, but switching is very much easier because the spring 4 is already tensioned is. The lifting of the locking lever 5 can be changed by adjusting the surface Io will.
