   Elektromagnetische Bremse. 



   Um eine Bremsvorrichtung zu betätigen, hat man in Fällen, wo elektrischer Strom zur Verfügung steht, eine magnetische Bremsung in der Weise eingerichtet, dass man Strom in eine Spule sendet, dadurch einen Kern aus weichem Eisen magnetisiert und die Kraft, mit der die Spule den   Kern (Zugmagneten)   in sich hinein zieht, dazu benutzt, um 
 EMI1.2 
 durch die Spule hindurch zu senden. Um den   Stromverbrauch   herabzusetzen, kann man die Einrichtung bekanntlich auch so treffen, dass man die Spule nur so lange vom Strom 
 EMI1.3 
   man   ihn hindert, nach Unterbrechung des Stromes in seine Anfangsstellung zurückzukehren. 



  Die vorliegende Erfindung erreicht das Aufhalten des Zugmagneten und damit das Feststellen des Bremsgestänges dadurch, dass eine von dem als Kolben ausgebildeten Kern 
 EMI1.4 
 durch ein Kern k angezogen und das Ventil   11   geöffnet wird. Unterbricht man den Hilfsstrom in der Spule i, nachdem der Kolben a in seine Anfangsstellung   zurückgekehrt   ist, so   fällt   der Hilfskolben k durch sein Eigengewicht in seine Anfangsstellung   zurück.

   Electromagnetic brake.



   In order to operate a braking device, in cases where electrical power is available, magnetic braking has been set up in such a way that one sends current into a coil, thereby magnetizing a core of soft iron and the force with which the coil breaks Core (pull magnet) pulls into itself, used to
 EMI1.2
 to send through the coil. As is well known, in order to reduce power consumption, the device can also be designed in such a way that the coil is only connected to the current for so long
 EMI1.3
   it is prevented from returning to its starting position after the current has been interrupted.



  The present invention achieves the stopping of the pull magnet and thus the fixing of the brake linkage in that one of the core, which is designed as a piston
 EMI1.4
 attracted by a core k and the valve 11 is opened. If the auxiliary current in the coil i is interrupted after the piston a has returned to its initial position, the auxiliary piston k falls back into its initial position under its own weight.

Claims

PATENT CLAIMS: EMI1.5 the sealing liquid formed or connected to the suction piston core of an electromagnet is moved by the current flowing through the solenoid in such a way that the brake is tightened and at the same time in any braking position by a flowing in and against the core or piston pressing, by a check valve on If the hindered liquid or a gas escapes for any length of time, even after the solenoid current has been switched off, it can be held and only released when the liquid or the gas has escaped in order to achieve the greatest possible savings in electrical power. <Desc / Clms Page number 2>

2. Embodiment of the electromagnetic brake according to claim 1, characterized in that an auxiliary coil opens a valve by attracting a core, whereby the path for the barrier fluid to flow back is released. EMI2.1
