Title (EN) ELECTRIC CAR
(FR) VOITURE ÉLECTRIQUE
(DE) ELEKTROAUTO
Abstract:
(EN) The invention relates to an electric car comprising (a) a first axle (12), (b) a second axle (14), (c) an electric motor (18) for driving at least one of the axles, which has an electric motor overall height (hM), and (d) a battery (22) for supplying the electric motor (18) with electrical energy, which has a battery overall height (hB), wherein (e) the electric motor overall height (hM) corresponds to the battery overall height (hB). According to the invention, it is provided that (f) the electric motor (18) is composed of at least two electric motor modules (38.1, 38.2) and that (g) the electric motor modules (38.1, 38.2) are arranged one behind the other with respect to a motor rotation axis (D18), (h) the electric motor modules (38.1, 38.2) have a common rotor shaft (40) or coupled rotor shafts (41), (i) the electric motor (18) and the battery are arranged on the same level, and (j) a battery mass point of gravity (S22) of the battery (22) is located in a central third (Q) between the axles (12, 14).
(FR) L'invention concerne une voiture électrique comprenant (a) un premier essieu (12), (b) un deuxième essieu (14), (c) un moteur électrique (18) destiné à entraîner au moins un des essieux et ayant une hauteur de moteur électrique (hM), et (d) une batterie (22) servant à alimenter en énergie électrique le moteur électrique (18) et ayant une hauteur de batterie (hB), (e) la hauteur de moteur électrique (hM) correspondant à la hauteur de batterie (hB). Selon l'invention, (f) le moteur électrique (18) est réalisé à partir d'au moins deux modules de moteur électrique (38.1, 38.2) et (g) les modules de moteur électrique (38.1, 38.2) sont disposés l'un derrière l'autre par rapport à un axe de rotation du moteur (D18), (h) les modules de moteur électrique (38.1, 38.2) possèdent un arbre de rotor commun (40) ou des arbres de rotor accouplés (41), (i) le moteur électrique (18) et la batterie sont disposés à la même hauteur et (j) le centre de gravité (S22) de la batterie (22) est situé dans un tiers central (Q) entre les essieux (12, 14).
(DE) Die Erfindung betrifft ein Elektroauto mit (a) einer ersten Achse (12), (b) einer zweiten Achse (14), (c) einem Elektromotor (18) zum Antreiben von zumindest einer der Achsen, der eine Elektromotor-Bauhöhe (hM) hat, und (d) einer Batterie (22) zum Versorgen des Elektromotors (18) mit elektrischer Energie, die eine Batterie-Bauhöhe (hB) hat, wobei (e) die Elektromotor-Bauhöhe (hM) der Batterie-Bauhöhe (hB) entspricht. Erfindungsgemäß ist vorgesehen, dass (f) der Elektromotor (18) aus zumindest zwei Elektromotor-Modulen (38.1, 38.2) aufgebaut ist und (g) die Elektromotor-Module (38.1, 38.2) bezüglich einer Motor-Drehachse (D18) hintereinander angeordnet sind, (h) die Elektromotor-Module (38.1, 38.2) eine gemeinsame Rotorwelle (40) haben oder gekoppelte Rotorwellen (41) besitzen, (i) der Elektromotor (18) und die Batterie auf gleicher Höhe angeordnet sind und (j) ein Batterie-Massenschwerpunkt (S22) der Batterie (22) in einem zentralen Drittel (Q) zwischen den Achsen (12, 14) liegt.
