   Vorrichtung zur Steuerung des Kupplungseingriffes bei automatisch betätigten Kupplungen, insbesondere für Kraftfahrzeuge

   Kupplungen nach Patent Nr. 216907In Anbetracht des geringen Querschnittes der Bohrung 10, die nur in der Grössenordnung von etwa 1 bis 2 mm Durchmesser ausgeführt werden kann, hat diese geringfügige Nebenluft keinen Einfluss auf den Startvorgang oder den Lauf des Motors. Bei geöffneter Startklappe 36 entsprechend Fig. 2 ist der Drehschieber 40 geschlossen, so dass sich der dann im Lufttrichter 34 herrschende dynamische Unterdruck auf die Membran im Steuerventil der Kupplung voll auswirken kann. 



   Durch die erfindungsgemässe Einrichtung wird auch bei vollständig geschlossener Startklappe die Weichheit des Kupplungseingriffes nicht   beeinträchtigt,   so dass bei Einschalten eines Getriebeganges in diesem Zustand auch bei erhöhter Motordrehzahl kein Ruck auftritt.

   Couplings according to patent no. 216907 In view of the small cross-section of the bore 10, which can only be made in the order of magnitude of about 1 to 2 mm in diameter, this slight additional air has no influence on the starting process or the running of the engine. When the starting flap 36 is open, as shown in FIG. 2, the rotary slide valve 40 is closed, so that the dynamic negative pressure then prevailing in the air funnel 34 can have a full effect on the membrane in the control valve of the clutch.



   The device according to the invention does not impair the softness of the clutch engagement even when the starting flap is completely closed, so that when a gear is switched on in this state, even with increased engine speed, no jerk occurs.

PATENTANSPRUCH : Vorrichtung zur Steuerung des Kupplungseingriffes bei automatisch betätigten Kupplungen von Kraftfahrzeugen unter Verwendung eines über ein Steuerventil druck-bzw. unterdruckbeaufschlagten Servomotors, dessen RestbelUftung entsprechend dem Stammpatent Nr. 216907 nach dem Kupplungsvorgang in Abhängigkeit von dem in dem Lufttrichter des Vergasers entstehenden Unterdruck erfolgt, dadurch gekennzeichnet, dass von der Verbindungsleitung (8) des Lufttrichters (34) des Vergasers (9) zum Steuerventil eine Leitung (38) zur Atmosphäre führt und der Durchflussquerschnitt der Leitung (38) in Abhängigkeit von der StartkIappe (6) des Motors regelbar ist. PATENT CLAIM: Device for controlling the clutch engagement in automatically operated clutches of motor vehicles using a pressure or control valve. Vacuum servomotor, the residual ventilation of which takes place according to the parent patent no.216907 after the coupling process depending on the vacuum created in the air funnel of the carburetor, characterized in that from the connecting line (8) of the air funnel (34) of the carburetor (9) to the control valve a Line (38) leads to the atmosphere and the flow cross-section of line (38) can be regulated as a function of the starter flap (6) of the engine.
