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.

Abstract: A power assembly and a vehicle. The power assembly includes a housing, and a first drive motor, a first speed reducer, a first oil path, a second drive motor, a second speed reducer, a second oil path, and a third oil path that are located inside the housing. The power assembly further includes a first oil pump and a second oil pump. The housing is provided with an oil pan. The first drive motor includes a first stator and a first rotor. The second drive motor includes a second stator and a second rotor. Both the first oil pump and the second oil pump are connected to the oil pan. The power assembly simplifies the oil paths in the housing and improve an integration level.
