Abstract
A hybrid coolant pump assembly comprises a housing, a bearing shaft, and an impeller apparatus. The bearing shaft is rotatably supported within an internal cavity of the housing. A first clutch is disposed on the bearing shaft and is operable to drivingly interconnect an input member and the bearing shaft when in an engaged state. The impeller apparatus is positioned about the bearing shaft and configured to pump a fluid. A rotor, disposed within the internal cavity of the housing, extends about the bearing shaft. A stator, disposed within the internal cavity of the housing, extends about the rotor. The rotor rotates relative to the stator and the bearing shaft when the stator is electrically energized. The impeller apparatus is rotatably driven by the bearing shaft when the first clutch is in the engaged state. The impeller apparatus is rotatably driven by the rotor when the stator is electrically energized.
