ABSTRACT:
A drive assembly including a prime mover, a primary energy accumulator, such as a flywheel, and an output shaft. Power distribution means, such as a differential gear arrangement, is provided for connecting the output shaft to both the energy accumulator and the prime mover. A clutch is provided for connecting the prime mover directly to the output shaft. A hydrostatic torque converter is operatively connected between the prime mover and the power distribution means, the torque converter including a hydraulic pump operated by the prime mover, a hydraulic unit in hydraulic circuit with the pump operable as both a pump and a motor, and a buffer energy accumulator connected to the unit. The prime mover may be an internal combustion engine or an electric motor, or the assembly may include both an engine and a motor alternatively connectable to the torque converter and to the output shaft.
