Problems solved by technology

[0004] The disadvantage here is that, on the one hand, in particular due to the subframe, a large installation space is required in order to fasten or support the drive unit with motor and transmission on the body
On the other hand, due to the limited installation space available on the corresponding axles of the electric vehicle, the production of the drive unit or the installation in the electric vehicle is labor-intensive, complex and expensive

Embodiment Construction

[0028] figure 1 A drive device with a drive unit according to the first embodiment of the invention is shown in plan view from above.

[0029] exist figure 1 In , reference numeral 1 denotes a drive unit for an electric vehicle. The drive unit 1 includes an electric motor 4 which is arranged in a housing 1 a of the drive unit 1 . The housing 1a of the drive unit 1 is in accordance with figure 1 It is substantially rectangular and is arranged with correspondingly longer sides on the cross member 2 of the bodywork of the electric vehicle. The cross member 2 is in turn connected to a side member 3 of the body of the electric vehicle, which extends parallel to the electric axle. In order to drive the wheels (not shown) of the electric vehicle, the drive unit 1 is connected with the figure 1 Cardan shafts 7 arranged on the left and right respectively in the y direction are connected. For supporting the drive unit 1 , an elastic spring guide 6 made of a fiber-plastic composite...

Abstract

The invention relates to a drive unit (1) for an electric vehicle having an electric machine (4) for driving an axle of the electric vehicle, which is arranged in a housing (1a), and having a drive axle (13) for transmitting a torque from the electric machine to the axle of the electric vehicle, and having at least one bearing device for supporting the drive unit on a bodywork of the electric vehicle, and is characterized in that the housing (1a) of the drive unit (1) is embodied as a bearing device for the drive unit on a bodywork of the electric vehicle. The invention likewise relates to a method for defining a drive unit in an electric vehicle and to a drive system for an electric vehicle having a drive unit.

Description

technical field [0001] The present invention relates to a drive unit for an electric vehicle, the drive unit comprising a motor for driving the electric vehicle, wherein the motor is arranged in a housing, and the drive unit comprises a motor for transferring torque from the motor A drive shaft, which is transmitted to an axle of the electric vehicle, and at least one bearing device for mounting the drive unit on the body of the electric vehicle. [0002] The invention also relates to a method for fastening a drive unit, in particular according to at least one of claims 1 to 12 , in an electric vehicle and to a drive system for an electric vehicle. Background technique [0003] A drive unit for an electric vehicle generally includes an electric motor with a drive shaft that ultimately drives a wheel or wheels of the electric vehicle via a transmission. In this case, instead of the internal combustion engine which is arranged centrally above the front axle in conventionally ...
