Abstract: A power assembly includes a rotor iron core, a gear set, a rotating shaft, and an oil-pumping system. The rotating shaft is fixedly connected to the rotor iron core and a driving gear in the gear set. The housing has an oil storage pool at a bottom and an oil collection tank at a high location, a part of a structure of a first gear in the gear set is located in the oil storage pool, and the first gear rotates to drive cooling oil in the oil storage pool to be raised and collected by the oil collection tank. The rotating shaft has a cooling oil channel inside. The cooling oil in the oil collection tank flows to the cooling oil channel, to dissipate heat from the rotor iron core.

Abstract: An oil inlet of a motor communicates with a first end of an oil pump through a first passage. A first oil sump of the motor communicates with a second end of the oil pump through a second passage. When the oil pump is rotating, a port at the first end is an oil outlet of the oil pump, and a port at the second end is an oil inlet of the oil pump. The first end of the oil pump communicates with a second oil sump through a third passage with a first valve. The second end of the oil pump communicates with the second oil sump through a fourth passage with a second valve. In this way, when the oil pump is reversing, coolant may be input into a motor cavity and accumulate in the motor cavity, so as to cool motor components in an immersion manner.
