(FR) ENSEMBLE MACHINE ÉLECTRIQUE
Abstract
(DE) Die Erfindung betrifft eine elektrische Maschinenanordnung (1), umfassend eine elektrische Maschine (2) für den Antrieb eines elektrisch antreibbaren Kraftfahrzeugs, mit einem Stator (3) und mit einem Rotor (4) sowie umfassend ein in drehfestem Kontakt mit dem Rotor (4) stehendes Abtriebselement (100). Gemäß der Erfindung ist zwischen der elektrischen Maschine (2) und dem Abtriebselement (100) ein axialelastisches Längenausgleichselement (5) zur Übertragung eines Drehmoments angeordnet.
(EN) The invention relates to an electric machine arrangement (1) comprising an electric machine (2) for driving an electrically drivable motor vehicle, having a stator (3) and having a rotor (4), and also comprising an output element (100) that is in rotationally fixed contact with the rotor (4). According to the invention, an axially elastic length-compensation element (5) for transmitting a torque is arranged between the electric machine (2) and the output element (100).
(FR) L'invention concerne un ensemble machine électrique (1) comprenant une machine électrique (2) pour l'entraînement d'un véhicule automobile électrique, composée d'un stator (3) et d'un rotor (4), et comprenant un élément de sortie (100) qui est en contact bloqué en rotation avec le rotor (4). Selon l'invention, un élément de compensation de longueur axialement élastique (5) destiné à transmettre un couple est disposé entre la machine électrique (2) et l'élément de sortie (100).
