The invention provides a vehicle and an electric machine configuration for a vehicle. A vehicle includes an electric machine. The electric machine is configured to propel the vehicle. The electric machine has a stator, a rotor and a labyrinth seal. The stator is fixed to the housing. The rotor is fixed to the shaft and configured to transmit rotational power generated by the motor to the at least one drive wheel via the shaft. A labyrinth seal is disposed between the shaft and the housing. The labyrinth seal includes an inner ring and an outer ring fixed to the shaft and the housing, respectively. The inner ring and the outer ring have staggered projections that define a tortuous channel extending axially between the first end and the second end of the labyrinth seal. Conductive lubricating grease is arranged in the zigzag channel. The inner ring, the outer ring, and the conductive grease are configured to direct an electric current induced in the shaft to the housing.

    本公开提供“车辆和用于车辆的电机配置”。一种车辆包括电机。电机被配置为推进车辆。电机具有定子、转子和迷宫式密封件。定子被固定到壳体。转子被固定到轴并且被配置为经由轴将电机产生的旋转动力传送到至少一个驱动轮。迷宫式密封件设置在轴和壳体之间。迷宫式密封件包括分别固定到轴和壳体的内环和外环。内环和外环具有交错突出部,所述交错突出部限定在迷宫式密封件的第一端和第二端之间轴向延伸的曲折通道。导电润滑脂设置在曲折通道内。内环、外环和导电润滑脂被配置为将轴中感应的电流引导到壳体。
