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 ...
