Description

  

  Einrichtung zum elektrischen Bremsen von Triebfahrzeugen mit Einphasen  Reihenschlussmotoren mittels Widerstandsbremsung der letzteren.    Die bisherigen     Widerstandsbremseinrich-          tungen    zum elektrischen Bremsen von Trieb  fahrzeugen mit     Einphasen-Reihenschlussmo-          toren    eignen sich bekanntlich nicht zur Still  standsbremsung, sofern nicht besondere Hilfs  mittel angewendet werden. Um diesen Man  gel zu beheben,     ist        erfindungsgemäss    die  Bremsanordnung derart umschaltbar, dass sie  auch als eine fremdgespeiste     Rückstrom-          Stillstandsbremse    verwendbar ist.

   Der Auf  wand an Mehrmaterial ist dabei im Verhält  nis zur Sicherheitserhöhung gering.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist in der beiliegenden Zeich  nung schematisch dargestellt.     Fig.    1 zeigt die  normale Schaltung für motorische Fahrt,       Fig.    2 die entsprechende Schaltung bei Wi  derstandsbremsung und     Fig.        ä    die     Zuschal-          tungs    für     Rückstrom-Stillstandslbremsung.    In  allen drei Figuren ist 1 der Fahrzeugtrans  formator. 2 eine     Überschaltspule,   <B>3</B> ein    Wendeschalter, 4 ein     Triebmotor-Rotor,    5  die     Triebmotor-Erregerwicklung    und 6 ein  Bremswiderstand.  



  Wie ersichtlich, wird der für die Schal  tung nach     Fig.    2 benötigte Widerstand 6  auch in der Schaltung nach     Fig.    $ benützt,  also durch einfache Umschaltung unter Ver  wendung des gleichen Bremswiderstandes die  normale Widerstandsbremsung in eine fremd  gespeiste     Rückstrom-Stillstandsbremsung    um  geschaltet.



  Device for electrical braking of traction vehicles with single-phase series motors by means of resistance braking of the latter. It is known that the previous resistance braking devices for the electrical braking of traction vehicles with single-phase series motors are not suitable for braking to a standstill unless special aids are used. In order to remedy this deficiency, according to the invention the brake arrangement can be switched in such a way that it can also be used as an externally fed reverse current standstill brake.

   The cost of additional material is low in relation to the increase in security.



  An embodiment of the subject invention is shown schematically in the accompanying drawing. 1 shows the normal circuit for motorized travel, FIG. 2 shows the corresponding circuit for resistance braking, and FIG. 1 shows the connection for reverse current standstill braking. In all three figures, 1 is the vehicle transformer. 2 a switchover coil, <B> 3 </B> a reversing switch, 4 a drive motor rotor, 5 the drive motor excitation winding and 6 a braking resistor.



  As can be seen, the resistor 6 required for the circuit according to FIG. 2 is also used in the circuit according to FIG. $, That is, the normal resistance braking is switched to an externally supplied reverse current standstill braking by simply switching using the same braking resistor.
