Abstract:
The invention relates to an electric vehicle (10) with an electric motor (18) wherein the electric motor (18) comprises (a) a first electric motor module (38.1) that features a first rotor (42.1) with a first rotor shaft (40.1) and whose rotor shaft (40.1) has a first shaft coupling structure (46a), and (b) at least a second electric motor module (38.2) that features a second rotor (42.2) with a second rotor shaft (40.2) and whose second rotor shaft (40.2) has a second shaft coupling structure (46b), and (c) a rotational bearing (68) by means of which the first rotor shaft (40.1) is mounted, wherein (d) the first rotor shaft (40.1) and the second rotor shaft (40.2) are positively coupled with one another by means of the shaft coupling structures (46). According to the invention, the shaft coupling structures (46) are at least partially surrounded by the rotational bearing (68).
