The invention provides a power system for a vehicle. A cooling system for guiding a fluid medium from an internal space of a housing to a bearing and a sealing assembly is formed in the power system for the vehicle, a first channel is formed in the housing, and a second channel is formed in a motor shaft. The first channel enables the internal space of the shell to be communicated with a first space defined by the shell, the motor shaft, the first sealing assembly and the first bearing, and the second channel enables the first space to be communicated with a second space defined by the motor shaft, the output shaft, the second sealing assembly and the second bearing. Therefore, by means of the structure, a part of fluid media can be guided to the positions where the bearings and the sealing assemblies are located from the inner space of the shell, so that the bearings and the sealing assemblies are lubricated and cooled, and the cooling and lubricating effects of the bearings and the sealing assemblies are improved.
本申请提供了一种车辆用动力系统。在该车辆用动力系统中形成有将流体介质从壳体的内部空间引导到轴承和密封组件的冷却系统,其中壳体形成有第一通道,电机轴形成有第二通道,第一通道使壳体的内部空间与壳体、电机轴、第一密封组件和第一轴承限定的第一空间连通,第二通道使上述第一空间与电机轴、输出轴、第二密封组件和第二轴承限定的第二空间连通。由此,利用上述结构,能够促使一部分流体介质从壳体的内部空间被引导到各轴承和密封组件所在的位置,从而对轴承和密封组件进行润滑和冷却,以改善轴承和密封组件的冷却和润滑效果。
