Hybrid power transfer module

A hybrid power transfer module including a drive shaft, a rotor hub, and an engine clutch defined by an annular shape having an inner circumference and an outer circumference, the drive shaft being coupled with the inner circumference of the engine clutch, comprising:

• a drive plate arranged on the outer circumference of the engine clutch;
• a torsional damper, which is arranged to contact the drive plate and includes a plurality of springs;
• and
• an oil passage in fluid communication with the engine clutch and/or the torsional damper,
• wherein the drive plate and the torsional damper are arranged within the rotor hub,
• wherein the engine clutch is configured to transmit engine torque to the drive plate when the engine torque is applied to the engine clutch,
• wherein the oil passage includes a first oil passage located radially inward of the engine clutch, and
• wherein the oil passage includes a second oil passage located radially outward of the engine clutch.

A hybrid power transfer module comprising:

• a drive shaft for transmitting engine torque;
• a rotor hub in which a rotor of a motor is mounted;
• an engine clutch connected to the drive shaft;
• and
• a torsional damper disposed between the engine clutch and the rotor hub,
• wherein the torsional damper includes a drive plate, one or more springs, and a rotor hub cover, and
• wherein the rotor hub and the rotor hub cover each includes a plurality of engagement portions configured to receive the springs of the torsional damper.
