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.
