Embodiment Construction

[0059] Figure 1a An electric vehicle 10 according to the invention is shown in the form of an electric vehicle having a first axle 12 in the form of a front axle and a second axle 14 in the form of a rear axle. Wheels 16.1, 16.2 are fastened to the first axle 12, wheels 16.3, 16.4 are fastened to the second axle 14. The electric motor 18 drives the wheels 16.1, 16.2 of the first axle 12 via a differential transmission 20, which can also be referred to as a differential.

[0060] The electric motor 18 is powered by a battery 22 . The battery 22 comprises at least two, in the present case eight battery cells 24.1, 24.2, . . . , 24.8. A battery is understood here to mean any type of assembly consisting of galvanic elements which is used to store or convert electrical energy for supplying the electric motor 18 .

[0061] It can be seen that the axis of rotation of the motor D 18 It extends between the battery cells 24.1, 24.3, 24.5, 24.7 on one side and the battery cells 24.2,...

Abstract

The invention relates to an electric vehicle (10) with an electric motor (18), comprising: (a) a first electric motor module (38.1) having a first rotor (42.1) with a first rotor shaft (40.1), and which rotor shaft (40.1) has a first shaft coupling structure (46a); (b) at least one second electric motor module (38.2) having a second rotor (42.2) with a second rotor shaft (40.2), and which 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; (d) wherein the first rotor shaft (40.1) andthe second rotor shaft (40.2) are interlockingly coupled to one another by means of the shaft coupling structures (46). According to the invention, the shaft coupling structures (46) are surrounded at least partially by the rotational bearing (68).

Description

technical field [0001] The invention relates to an electric vehicle having an electric motor in the form of a permanently excited synchronous motor comprising: (a) a first motor module having a first rotor having a first rotor shaft , and the rotor shaft of the first motor module has a first shaft coupling structure; and (b) at least one second motor module, the second motor module has a second rotor, the second rotor has a second rotor shaft, and the The second rotor shaft of the second motor module has a second shaft coupling structure; and (c) a rotary support by which the first rotor shaft is supported, wherein (d) the first rotor shaft and the second rotor shaft are supported by These coupling structures are positively coupled to each other. Furthermore, the invention also relates to an electric motor having the stated properties, which is designed in particular, but not necessarily, for an electric vehicle. [0002] Furthermore, the present invention relates to an elec...
