Abstract
(DE)
Die Erfindung betrifft eine Bürstenvorrichtung (1) zur elektrischen Verbindung eines ersten Elements (2A) mit einem um eine Rotationsachse (L) relativ zu dem ersten Element (2A) drehbaren zweiten Element (2B), wobei die Bürstenvorrichtung (1) in einem Kontaktbereich (1A) zum elektrischen Kontakt mit dem zweiten Element (2B) eine zur Rotationsachse (L) schraubenförmig verlaufende Struktur (1B, 1B', 1B'') aufweist. Die Erfindung betrifft auch eine E-Maschine (2) mit einer solchen Bürstenvorrichtung (1), und die Erfindung betrifft auch eine Antriebsvorrichtung zum elektrischen Antrieb eines Kraftfahrzeugs mit einer solchen E-Maschine (2).
(EN)
The invention relates to a brush device (1) for electrically connecting a first element (2A) to a second element (2B) which can be rotated about a rotational axis (L) relative to the first element (2A), wherein, in a contact region (1A) for electrically contacting the second element (2B), the brush device (1) comprises a structure (1B, 1B', 1B'') extending helically with respect to the rotational axis (L). The invention further relates to an e-machine (2) having such a brush device (1) and to a drive device for electrically driving a motor vehicle having such an e-machine (2).
(FR)
L'invention concerne un dispositif à balai (1) pour la connexion électrique d'un premier élément (2A) à un deuxième élément (2B) tournant autour d’un axe de rotation (L) par rapport au premier élément (2A), ledit dispositif à balai présentant une structure (1B, 1B', 1B'') hélicoïdale par rapport à l’axe de rotation (L) dans une zone de contact (1A) pour le contact électrique avec le deuxième élément (2B). L'invention concerne également une machine électrique (2) équipée d'un tel dispositif à balai (1), et l'invention concerne aussi un dispositif d'entraînement destiné à entraîner électriquement un véhicule automobile au moyen d’une telle machine électrique (2).
