  • Patent number: 10971961
    Abstract: A rotor sleeve provides a direct cooling method in which oil flows into the rotor sleeve via a flow passage formed through an input shaft of a transmission and is distributed to a motor coil of a driving motor to cool the motor coil. The rotor sleeve has a flow passage structure capable of maintaining a balance between the amount of oil to be distributed toward a transmission and the amount of oil to be distributed toward an engine.
