Description
<Desc/Clms Page number 1>
Mit Nocken oder Kurvenscheiben versehenen Kontroller zur Fernsteuerung von
EMI1.1
EMI1.2
<Desc/Clms Page number 2>
gemacht. Die Nockenschaltelemente können entweder als einfache Schalter oder als Umschalter ausgebildet sein. Im letzteren Falle erfolgt die Schaltung in der einen Richtung der Kontrollerwalze durch die Nockenscheibe, wobei die Feder h zusammengedrückt wird, während die
Schaltbewegung in der anderen Richtung durch die Feder h herbeigeführt wird. Die Feder 7t muss also kräftiger sein als die Kontaktfeder e. Um nun ein zu starkes Durchbiegen der Kontaktfeder zu verhindern. ist diese mit einem Begrenzungsanschlag k versehen. Das gleiche wird erreicht durch Hubbegrenzung der Feder h.
Die Reibrollen f der Schaltelemente werden zweckmässig aus Isoliermaterial hergestellt, wodurch die spannungsführenden Teile der Kontroller gegen Erde isoliert sind.
PATENT-ANSPRÜCHE :
1. Mit Kurvenscheiben oder Nocken arbeitender Kontroller zur Fernsteuerung elektromotorisch oder pneumatisch betätigter, zur Regelung elektrischer Triebfahrzeuge dienender Schaltapparat, dadurch gekennzeichnet. dass die zur elektrischen Steuerung der die Hauptströme regelnden Schaltapparate dienenden, von der Nockenwalze direkt betätigten Schaltelemente (c. dj als Umschalter ausgebildet sind.

Controllers equipped with cams or cams for remote control of

made. The cam switching elements can either be designed as simple switches or as changeover switches. In the latter case, the control roller is switched in one direction by the cam disk, the spring h being compressed while the
Switching movement in the other direction is brought about by the spring h. The spring 7t must therefore be stronger than the contact spring e. In order to prevent the contact spring from bending too much. this is provided with a limit stop k. The same is achieved by limiting the stroke of the spring h.
The friction rollers f of the switching elements are expediently made of insulating material, as a result of which the live parts of the controller are isolated from earth.
PATENT CLAIMS:
1. Controller working with cams or cams for remote control of an electric motor or pneumatically operated switching device used to regulate electric traction vehicles, characterized. that the switching elements (c. dj) used for the electrical control of the switching devices regulating the main currents and actuated directly by the cam roller are designed as changeover switches.
