Abstract:
A drive module with a housing, an electric motor, a coolant sump, an inlet pipe and a transmission and differential assembly that is driven by the electric motor to drive a pair of output members. The electric motor is coupled to the housing and has a stator, which is fixedly coupled to the housing, and a rotor that is rotatable within the stator. The rotor has a coolant passage, which extends parallel to a rotational axis of the rotor, and a nozzle passage that intersects the coolant passage and extends radially outwardly therefrom. The coolant sump is configured to hold a coolant fluid. The inlet pipe is in fluid communication with the coolant sump and is received into the coolant passage. The inlet pipe is configured to feed the coolant fluid from the coolant sump into the coolant passage. The coolant fluid is gravity fed into the inlet pipe.
