The embodiment of the invention provides a driving motor for an electric vehicle, a power assembly and the electric vehicle, an end cover of a shell of the driving motor comprises a mounting groove and two side faces, one side face faces a rotor of the driving motor, and the other side face deviates from the rotor of the driving motor. The groove bottom or the groove wall of the installation groove comprises an open hole. One side face comprises a bearing groove, the other side face is used for fixing a cover plate, and the cover plate is used for enclosing the other side face to form a containing cavity. A through hole is formed in the groove bottom of the bearing groove and used for communicating the bearing groove with the containing cavity, so that oil gas on one side of the bearing groove flows into the containing cavity through the through hole. The other side surface comprises another open hole, the other open hole is exposed out of the accommodating cavity and is used for being communicated with one open hole through an internal channel of the end cover, and the axis of one open hole is intersected with the axis of the mounting groove, so that oil gas entering the accommodating cavity passes through the internal channel of the end cover from the other open hole and is arrayed through one open hole with an inclined axis; and an oil-gas condensation path is prolonged.
本申请实施例提供一种用于电动车辆的驱动电机、动力总成及电动车辆,驱动电机的壳体的端盖包括安装槽和两个侧面,一个侧面朝向驱动电机的转子,另一个侧面背离驱动电机的转子。安装槽的槽底或槽壁包括一个开孔。一个侧面包括轴承槽,另一个侧面用于固定盖板,盖板用于围合另一个侧面形成容纳腔。轴承槽的槽底包括通孔,通孔用于连通轴承槽和容纳腔,使得轴承槽一侧的油气通过通孔流动到容纳腔。另一个侧面包括另一个开孔,另一个开孔暴露于容纳腔,另一个开孔用于通过端盖的内部通道连通一个开孔,一个开孔的轴线相交于安装槽的轴线,使得进入容纳腔的油气从另一个开孔经过端盖的内部通道以及轴线倾斜的一个开孔排列,延长油气的冷凝路径。
