Abstract
(DE)
Die Erfindung betrifft einen elektrischer Achsantrieb (10) für ein Kraftfahrzeug, mit wenigstens einem Elektromotor (12), mit einem von dem Elektromotor (12) antreibbaren Differentialgetriebe (14), mit einem ersten Gehäuseteil (16), welches das Differentialgetriebe (14) zumindest teilweise umgibt, mit einem separat von dem ersten Gehäuseteil (16) ausgebildet zweiten Gehäuseteil (18), welches den Elektromotor (12) zumindest teilweise umgibt, und mit einem separat von dem ersten Gehäuseteil (16) und separat von dem zweiten Gehäuseteil (18) ausgebildeten dritten Gehäuseteil (20), wobei das erste Gehäuseteil (16) und das zweite Gehäuseteil (18) mittels einer ersten Flanschverbindung (22) unmittelbar miteinander verbunden sind, und wobei das zweite Gehäuseteil (18) und das dritte Gehäuseteil (20) mittels einer dritten Flanschverbindung (24) unmittelbar miteinander verbunden sind, wobei das dritte Gehäuseteil (20) dazu ausgebildet ist, ein Teilgetriebe (26) zur Anbindung des Differentialgetriebes (14) an den Elektromotor (12) zumindest teilweise zu lagern, wobei das erste Gehäuseteil (16) und das dritte Gehäuseteil (20) mittels einer zweiten Flanschverbindung (32) unmittelbar miteinander verbunden sind.
(EN)
The invention relates to an electric axle drive (10) for a motor vehicle, having at least one electric motor (12), having a differential transmission (14) which can be driven by the electric motor (12), having a first housing part (16) which at least partially surrounds the differential transmission (14), having a second housing part (18) which is formed separately from the first housing part (16) and which at least partially surrounds the electric motor (12), and having a third housing part (20) which is formed separately from the first housing part (16) and separately from the second housing part (18), wherein the first housing part (16) and the second housing part (18) are directly connected to one another by means of a first flange connection (22), and wherein the second housing part (18) and the third housing part (20) are directly connected to one another by means of a third flange connection (24), wherein the third housing part (20) is designed for at least partially bearing a partial transmission (26) for the connection of the differential transmission (14) to the electric motor (12), wherein the first housing part (16) and the third housing part (20) are directly connected to one another by means of a second flange connection (32).

L'invention concerne un entraînement (10) d'essieu électrique pour un véhicule à moteur, comprenant au moins un moteur électrique (12), un engrenage différentiel (14) pouvant être entraîné par le moteur électrique (12), une première partie de boîtier (16), laquelle entoure au moins en partie l'engrenage différentiel (14), une deuxième partie de boîtier (18) réalisée séparément de la première partie de boîtier (16), laquelle entoure au moins en partie le moteur électrique (12), et une troisième partie de boîtier (20) réalisée séparément de la première partie de boîtier (16) et séparément de la deuxième partie de boîtier (18). La première partie de boîtier (16) et la deuxième partie de boîtier (18) sont reliées entre elles directement au moyen d'un premier système de raccordement à bride (22). La deuxième partie de boîtier (18) et la troisième partie de boîtier (20) sont reliées entre elles directement au moyen d'un troisième système de raccordement à bride (24). La troisième partie de boîtier (20) est réalisée pour monter au moins en partie un engrenage partiel (26) servant à attacher l'engrenage différentiel (14) au moteur électrique (12). La première partie de boîtier (16) et la troisième partie de boîtier (20) sont reliées entre elles directement au moyen d'un deuxième système de raccordement à bride (32).
