Definitions

  • the invention relates to a windshield wiper device, in particular for a motor vehicle, with at least one output shaft on which a crank is arranged.
  • the output shaft has an external thread onto which a nut can be screwed for rotationally fixed attachment of the crank to the output shaft.
  • the output shaft must protrude at least about the extent of the thickness of the nut on the crank.
  • the invention therefore has the object to provide a windshield wiper device of the type mentioned, which requires less installation space than before.
  • the invention solves this problem with the windshield wiper device of the type mentioned above, in which, according to the invention, an output shaft can be fastened exclusively and / or predominantly in a form-fitting manner with a crank.
  • the positive fastening between the at least one output shaft and the crank can be realized in a particularly simple and cost-effective manner if the output shaft has a cylindrical outer knurling.
  • the crank with the cylindrical outer knurling can be reliably fixed without rotation on the output shaft without a screw.
  • the output shaft may have an inner bore.
  • the inner bore can be provided with an internal thread.
  • a screw can be used as an assembly aid. By using the screw as an assembly tool, no external pressure must be exerted on the entire windshield wiper device. Thus, pressure sensitive components, such as sensors placed below the crank, can be protected from damage.
  • the crank can be mounted with a screwing on the at least one output shaft.
  • the fastening process can be automated, while at the same time pressure-sensitive components arranged below the crank are spared.
  • the screwing tool can be screwed into the inner bore, wherein it cuts an internal thread in the inner bore or nachformt an existing internal thread, to any geometric changes after a thermal or me- to eliminate chanical treatment of the output shaft.
  • the screwed-in screwing tool arrests the output shaft during assembly in the axial direction.
  • the screwing tool can be equipped with a hold-down punch.
  • the hold-down temple presses after the complete screwing of the screwing the crank on the at least one output shaft.
  • the crank when unscrewing the screwing tool can not be solved or twisted by the at least one output shaft.
  • the screwing tool can be actuated hydraulically or pneumatically.
  • the crank can be secured axially with a short screw.
  • This screw can be significantly shorter than the screw, which can be used instead of the screwing tool.

Abstract

L'invention concerne un dispositif essuie-glace (10), en particulier pour un véhicule automobile, comprenant au moins un arbre de sortie (102) sur lequel est disposée une manivelle (101). Dans le cas des dispositifs essuie-glace connus de l'état de la technique, l'arbre de sortie présente un filetage externe sur lequel on peut visser un écrou pour la fixation solidaire en rotation à l'arbre de sortie. Ce type de fixation n'est toutefois plus adapté aux exigences actuelles croissantes en matière de réduction maximale de l'encombrement. De ce fait, avec le dispositif essuie-glace (10) selon l'invention, l'arbre de sortie (102) peut être fixé à la manivelle exclusivement et/ou essentiellement par engagement par coopération de forme.
