ABSTRACT:
An electric motor is connected solidly to the main transmission oil pump shaft on the transmission case. An off-axis chain and gear are connected to the main oil pump shaft via a single freewheeling clutch, so that either source of torque in a hybrid motor can drive the oil pump or the oil pump can be driven by the electric motor or the hybrid motor depending on which motor is traveling at a higher speed.
