Description

Ausschaltvorrichtung, insbesondere für elektrische Kraftfahrzeuge Im Patent 417 907 ist eine Einrichtung an Bremsen, insbesondere für Kraftfahrzeuge. beschrieben, bei .denen die Bremse beim Fahren durch einen Fußtritt entgegen einer Bremsfederkraft gelüftet wird, indem eine auf (las Bremsgestänge wirkende Klinke, welche den Fußtritt von der Bremsfederkraft entlastet, beim Abheben des Fußes durch die Bewegung des Fußtritts selbsttätig ausgelöst wird.Disconnection device, especially for electric motor vehicles. Patent 417 907 describes a device on brakes, especially for motor vehicles. where the brake is released when driving by kicking against a brake spring force, in that a pawl acting on the brake linkage, which relieves the brake spring force on the kick, is automatically triggered when the foot is lifted by the movement of the kick.

Es ist auch bereits berannt, durch die Bremsfederkraft einen Schalter zu öffnen, der den Fahrstrom abschaltet, und die Bremsfeder sowie den den Fahrstrom schaltenden Hebel mit der Fahrschaltwalze derart zu verbinden, daß das Lösen ,der Bremse :und das Einschalten des Fahrstromes nur in der Ausrückstellung der Fahrschaltwalze erfolgen kann.It is also already overrun, by the brake spring force a switch to open, which switches off the traction current, and the brake spring and the traction current to connect shifting lever with the drive shift drum in such a way that the release, the Brake: and switching on the drive current only when the drive shift drum is disengaged can be done.

Brei elektrisch betriebenen Kraftfahrzeugen nach dem Patent ist es ,aber erwünscht, daß die Fahrschaltwalze bei Abheben des Fußes selbsttätig in die Awsrückstellung zurückgeführt wird, damit nicht @beim Wiederbesteigen des Fußtrittes das Fahrzeug mit derselben Geschwindigkeit wie vor dem Bremsen anfährt.Pulp electrically powered motor vehicles according to the patent is there , but it is desirable that the drive shift drum automatically moves into the Awsrückstellung is returned, so that not @ when you step back on the kick the vehicle starts moving at the same speed as before braking.

Erfindungsgemäß erfolgt dies dadurch, daß .das Bremsgestänge derart mit der Fahrschaltwalze verbunden ist, daß diese beim Abheben des Fußes von der Trittplatte durch eine Federkraft in die Ausrückstellung gedreht wird. Als Federkraft kann eine besondere Feder oder auch die vorhandene Bremsfeder benutzt werden, wie sie bei Kraftfahrzeugen nach :dem Hauptpatent vorgesehen ist. Die Abbildung zeigt ein Ausführungsbeispiel nach der Erfindung, :bei .der die gleichen Bezeichnungen wie beim Hauptpatent gewählt sind.According to the invention, this is done in that .the brake linkage in such a way is connected to the drive shift drum that this when you lift your foot from the The step plate is rotated into the disengaged position by a spring force. As spring force a special spring or the existing brake spring can be used, such as it is provided for motor vehicles according to: the main patent. The figure shows an embodiment according to the invention: in .der the same designations as are chosen for the main patent.

Durch die Klinke k wird der Fußtritt lx von Ader Zugfeder r entlastet, die an der Stange f angreift. Die Stange f besitzt an ihrem oberen Ende einen Schlitz s, in dem sich ein Vorsprung t des Schalthebels z4 der Schaltwalze v normalerweise beim Aus- und Einschalten des Fahrwerkes bewegt. Verläßt nunmehr der Fuß den Fußtritt h, so zieht nach Ausklinken der Klinke k .die Zugfeder r die Stange f nach oben und nimmt durch das untere Ende des Schlitzes s den Vorsprung t des in Fahrstellung befindlichen Schalthebels 24 mit, so @daß die Schaltwalze selbsttätig in die Ausrückstellung biewegt wird. An der Stange f kann, wie im Hauptpatent beschrieben, auch das Bremsgestänge d angreifen, so @daß sich die besondere Zugfeder r erfibrigt und die Bremsfeder deren Arbeit übernimmt.The pawl k relieves the treadle lx from the tension spring r, which engages the rod f. The rod f has a slot s at its upper end, in which a projection t of the shift lever z4 of the shift drum v normally moves when the undercarriage is switched on and off. If the foot now leaves the footstep h, after releasing the pawl k .the tension spring r pulls the rod f upwards and through the lower end of the slot s takes the projection t of the shift lever 24 in the driving position with it, so that the shift drum automatically is moved into the disengagement position. As described in the main patent, the brake linkage d can also attack the rod f, so that the special tension spring r is required and the brake spring takes over its work.
