Description

  

  Fahrschalter,     insbesondere    für elektrische Triebfahrzeuge.    Bei Fahrschaltern, insbesondere für elek  trische Triebfahrzeuge, wird eine Kontakt  gruppe in vielen Fällen zur direkten oder  indirekten Regulierung der Geschwindigkeit  benützt, wobei mit Rücksicht auf die höchst  zulässigen     Zugkraft-bezw.Drehmomentschwan-          kungen    unter Umständen viele Regulierstufen  und dementsprechend grosse     Schattwalzen-          und        Fahrschalterabmessungen    resultieren.  



  Gegenstand vorliegender Erfindung ist  nun ein Fahrschalter, bei welchem es mög  lich ist, bei an und für sich gleicher     Regu-          lierstufenzahl,    eine wesentlich kleinere An  zahl von Kontakten und kleinere Fahrschalter  dimensionen zu erreichen.  



  Die beiliegende Zeichnung zeigt ein Aus  führungsbeispiel des Erfindungsgegenstandes.  A stellt die Fahrkurbel eines Fahrschal  ters dar; B ist ein     Regulier-Walzenbelag,     der von der Fahrkurbel aus über eine Über  setzung 1 : 1 angetrieben wird, also ebenfalls  eine Umdrehung gleichzeitig mit der Fahr  kurbel macht.     a-k    sind die zugehörigen    Kontaktfinger. C ist ein Walzenbelag, der  über eine Übersetzung 1:2 von derselben  Fahrkurbel A aus angetrieben wird, und  durch den die Kontakte     d    und<I>m</I> geschaltet  werden. Dieser Belag macht     halbsoviele    Um  drehungen wie die Fahrkurbel und der Belag  B. E und F sind Regulierwiderstände gleichen       Ohmwertes;    D ist eine Erregerwicklung für  eine Dynamo.

    



  Auf den Regulierstufen 0-10 erfolgen  die Schaltungen des Widerstandes E     mit-          telst    des Walzenbelages B und der Kontakte       a-k,    beispielsweise die allmähliche Wider  standsabschaltung. Beim     Weiterschalten    auf  Stufe 11 läuft der Walzenbelag C auf die  Kontakte     l    und<I>m</I> auf und hält die von  Belag B zuletzt herbeigeführten Widerstands  verhältnisse bezüglich des     Ohmwertes    auf  recht. Dadurch wird der Walzenbelag B mit  den Kontakten     a-k    für eine zweite Schalt  folge auf den Regulierstufen 11-20 frei,       bezw.    der Regulierwiderstand E wird ein  zweites Mal bis auf 0 abgeschaltet.

   Durch  Änderung des Übersetzungsverhältnisses zwi-      sehen Fahrkurbel und Belag C (z. B. von  1:2 auf 1:3, 1:4 usw.) und durch ent  sprechende Änderung des Belages C und Ver  wendung mehrerer Widerstände F kann der  Belag B     _    auch mehr wie zweimal benützt  werden und so die Stufenzahl entweder er  höht oder die Kontaktzahl bei gleicher Stufen  zahl vermindert werden.



  Driving switches, in particular for electric traction vehicles. With travel switches, especially for electric traction vehicles, a contact group is used in many cases for direct or indirect regulation of the speed, with many regulation levels and correspondingly large shadow roller and travel switch dimensions in consideration of the maximum permissible tensile force or torque fluctuations result.



  The subject matter of the present invention is a travel switch, in which it is possible to achieve a significantly smaller number of contacts and smaller travel switch dimensions with the same number of regulating stages.



  The accompanying drawing shows an exemplary embodiment from the subject of the invention. A represents the crank of a driving switch; B is a regulating roller covering that is driven by the travel crank via a ratio of 1: 1, i.e. it also makes one revolution at the same time as the travel crank. a-k are the associated contact fingers. C is a roller covering which is driven by the same crank A via a ratio of 1: 2 and through which the contacts d and <I> m </I> are switched. This covering makes half as many turns as the crank and the covering B. E and F are regulating resistors of the same ohmic value; D is an excitation winding for a dynamo.

    



  The switching of the resistor E by means of the roller covering B and the contacts a-k, for example the gradual switch-off of the resistor, takes place at the regulation levels 0-10. When you switch to level 11, the roller coating C runs against the contacts 1 and <I> m </I> and maintains the resistance conditions last brought about by coating B with regard to the ohmic value. As a result, the roller covering B with the contacts a-k for a second switching sequence on the regulating stages 11-20 free, respectively. the regulating resistor E is switched off a second time down to 0.

   By changing the transmission ratio between crank and surface C (e.g. from 1: 2 to 1: 3, 1: 4 etc.) and by changing the surface C accordingly and using several resistors F, surface B can be _ can also be used more than twice and so either the number of stages is increased or the number of contacts is reduced with the same number of stages.

PATENTANSPRUCH: Fahrschalter, insbesondere für elektrische Triebfahrzeuge, dadurch gekennzeichnet, dass derselbe mit zwei Kontaktgruppen ausgerüstet ist, von denen die eine zur Vornahme eines wiederholten Schaltvorganges bei gleichblei bendem Schaltsinne benützbar ist, während die andere jeweilen nach Beendigung je eines solchen Schaltvorganges die ,zur Wiederbe nützung der ersten Kontaktgruppe nötige Umschaltung vollzieht. PATENT CLAIM: Driving switch, in particular for electric traction vehicles, characterized in that it is equipped with two contact groups, one of which can be used to carry out a repeated switching process with the same switching direction, while the other can be used to re-switch after each such switching process has ended using the first contact group.
