Description

Das P tent 8.26 451 betrifft eine Befestigungsanordnung der Widerstandswendeln in Rahmenwiderständen elektrischer Triebfahrzeuge, dergestalt, daß die Wendeln ohne angebogene Ösen oder gerade Enden mit ihrer Stirnseite unmittelbar gegen eine zur Wendelachse senkrecht stehende Fläche gepreßt werden, wobei die Achse der Befestigungssch@aube parallel' zur Wendelachse liegt und die Druckfläche des Klemmkörpers quer zur Wendelachse steht.The P tent 8.26 451 relates to a fastening arrangement of the resistance coils in frame resistors of electric traction vehicles, such that the coils without bent eyelets or straight ends are pressed with their end face directly against a surface perpendicular to the coil axis, the axis of the fastening screw parallel 'to the Helical axis lies and the pressure surface of the clamping body is transverse to the helical axis.

Die nachstehend beschriebene Erfindung stellt eine vorteilhafte Weiterbildung des Gegenstandes des Hauptpatents dar. Nach der Erfindung wird die Widerstandswendel mit ihrer Endwindung ebenfalls gegen .eine zur Wendelachse querstehende Fläche gepreB.t, jedoch nicht mit der Außenseite, sondern mit der Rück- oder Innenseite der Windung. Der die Gegenfläche bildende Träger wird also hinter die Endwindung geschoben. Diese Anordnung hat den Vorteil, daß die Wendel mit dem Träger auch, dann in Berührung bleibt, wenn die Druckschraube infolge Überbeanspruchung durch unsachgemäßes Anziehen oder infolge eines Fehlers im Werkstoff abbrechen sollte. Die Wendel bleibt dann nämlich mit ihrer Endwindung am Träger eingehängt. Bild i stellt eine konzentrische Anordnung der Wendelbefestigung nach der Erfindung dar. Der Träger wird von dem Winkelprofil i gebildet, dessen einer Schenkel senkrecht steht und ,hinter die Endwindung der Widerstandswendel 2 greift. Vor der eingehängten Windung befindet sich das Klemmstück 3, das durch ,die Schraubenmutter der Befestigungsschraube 4 angedrückt wird.The invention described below represents an advantageous development of the subject matter of the main patent. According to the invention, the resistance coil with its end turn also pressed against a surface transverse to the helix axis, but not with the outside, but with the back or inside of the turn. The carrier forming the opposite surface is thus pushed behind the end turn. These Arrangement has the advantage that the helix is then also in contact with the carrier remains if the pressure screw is overstressed due to improper tightening or should break off as a result of a fault in the material. The coil then remains namely hung with its end turn on the carrier. Image i represents a concentric Arrangement of the spiral fastening according to the invention. The carrier is of the Angular profile i formed, one leg of which is perpendicular and behind the end turn the resistance coil 2 engages. The clamping piece is located in front of the hooked-in coil 3, which is pressed by, the nut of the fastening screw 4.

In Bild 2 ist eine Doppelbefestigung für zwei Wendeln wiedergegeben. Der Winkelträger i und die Widerstandswendeln 2 haben die gleiche Lage zueinander wie in Bild i. Die ersten Windungen beider Widerstandswendeln werden von dem zwischen ihnen liegenden gemeinsamen Klemmstück 3 gegen ihre Unterlage gepreßt. Auf je zwei Wendeln entfallen daher auch nur eine gemeinsame Befestigungsschraube 4 und eine Schraubenmutter 5.Figure 2 shows a double attachment for two coils. The angle bracket i and the resistance coils 2 are in the same position with respect to one another as in picture i. The first turns of both resistance coils are from the between them lying common clamping piece 3 pressed against their base. On two each Spirals are therefore also only a common fastening screw 4 and one Screw nut 5.
