Abstract

Elektrische Maschine, insbesonder Drehstromgenerator für Kraftfahrzeuge mit einem Läufer, der mindestens einen Schleifkontakt aufweist, und mit einem Bürstenhalter (11), der mit mindestens einer Kohlebürste (16) zur Stromversorgung des Läufers mit dessen Schleifkontakt zusammenwirkt, wobei die mindestens eine Kohlebürste in einem Köcher (17) axial beweglich geführt ist und von einer dahinter im Köcher (17) vorgespannten Schraubenfeder (18) druckbeaufschlagt ist. Eine Anschlusslitze (20) der Kohlebürste (16) ist durch die-Schraubenfeder (18) hindurchgeführt und an ihrem äußeren Ende (20a) mit einem Anschlussteil (22) mit Abstand zur Längsachse des Köchers (17) fest verbunden.Electric machine, in particular three-phase motor vehicle generator with a rotor having at least one sliding contact, and with a brush holder (11) which cooperates with at least one carbon brush (16) to supply the rotor with its sliding contact, wherein the at least one carbon brush in a quiver (17) is guided axially movable and by a behind in the quiver (17) biased coil spring (18) is pressurized. A pigtail (20) of the carbon brush (16) is passed through the coil spring (18) and at its outer end (20a) with a connecting part (22) fixedly spaced from the longitudinal axis of the quiver (17).

Um ein Stauchen und Verklemmen der Anschlusslitze im Bereich der Schraubenfeder (18) zu vermeiden, ist das äußere Ende (20a) der Anschlusslitze (20) in einem losen Bogen zu der Verbindungsstelle (21) mit dem Anschlussteil (22) geführt.

Figure imgaf001
In order to avoid compression and jamming of the pigtail in the region of the helical spring (18), the outer end (20a) of the pigtail (20) is guided in a loose arc to the connection point (21) with the connecting part (22).
