Abstract
[Subject]In a hybrid drive power apparatus, loss of drive power caused by drag torque of a friction clutch is decreased to reduce fuel consumption rate.[Solution]A hybrid drive power apparatus of the type which comprises a first gear-shift mechanism assembled with a first input shaft to be applied with drive power from an engine through a first friction clutch, a second gear-shift mechanism assembled with a second input shaft to be applied with the drive power of the engine through a second friction clutch, a motor-generator in drive connection with the second input shaft, a final output shaft in drive connection with each output shaft of both the gear-shift mechanisms, and a driven mechanism to be driven by drive power transferred from the final output shaft, wherein drive torque of the motor-generator activated as an electric motor is transferred to the final output shaft through a gear set as a shift step selected in the second gear-shift mechanism, wherein the hybrid drive power apparatus includes control means for activating the motor-generator as the electric motor in a condition where the first friction clutch is brought into engagement to transfer drive torque of the engine…
