Embodiment Construction
[0023] exist figure 1 A motor vehicle 1 is shown in , which has an electric machine 2 which is to be supplied by a battery 3 or by the on-board electrical system. Electric machine 2 may in particular be a drive motor of motor vehicle 1 . For the sake of clarity, the drive train of the motor vehicle and the shaft of the electric machine 2 connected thereto are not shown.
[0024] The electric machine 2 should be supplied with a three-phase alternating voltage, while the battery 3 or the vehicle grid supplies a direct voltage. Thus, the electric machine 2 is connected to the battery 3 or the on-board electrical network via a converter / inverter 4 . Electric machine 2 and converter 4 together form drive 29 for motor vehicle 1 . The converter 4 has a DC voltage connection 5 for connection to the battery 3 and a plurality of converter contact elements 6 electrically conductively connected to the motor contact elements 7 in order to enable the electrical machine 2 to be energized....

A drive, in particular for a motor vehicle, comprising an electric motor and a converter, wherein the motor has at least one electrically conductive motor contact element for electrical contact with a corresponding electrically conductive converter contact element of the converter, wherein the motor contact element holding directly or via a motor seal on the motor housing component of the motor housing of the electric motor and the converter contact element being held directly or via the converter seal on the converter housing component of the converter housing of the converter, The motor contact element and the converter contact element are mechanically fastened to each other by fastening means, the fastening part and the corresponding section of the motor contact element and the corresponding section of the converter contact element located outside the housing are accommodated in the fluid In the sealed receiving space, the receiving space is at least partially formed by the converter housing assembly and the motor housing assembly.
Description
technical field [0001] The invention relates to a drive, in particular for a motor vehicle, comprising an electric motor and a converter, wherein the motor comprises at least one electrically conductive motor contact element for electrically contacting a corresponding electrically conductive converter contact element of the converter. touch. Furthermore, the invention relates to a motor vehicle. Background technique [0002] Converters are often used to supply electric machines, in particular high-power electric machines, which can be used as drive motors in motor vehicles, for example, in order to provide an AC voltage for operating the electric machine. Such a converter can be fed, for example, in a motor vehicle via the direct current system of the motor vehicle or via the vehicle battery. In this case, it is often advantageous first to design the converter and the electric machine as separate components. However, since high power can be supplied via the electrical con...
