Abstract

A DRIVE SIDE POWER UNIT, WHICH MAY INCLUDE THE ROTATIONAL OUTPUT SHAFT OF AN INTERNAL COMBUSTION ENGINE, DRIVES A FRONT SECTION LOAD, AND IS ALSO COUPLED TO A DIFFERENTIAL DRIVE DEVICE (M101) MADE UP OF AN ELECTRICAL MACHINE (U101) AND A REAR DIFFERENTIAL GEAR BOX. THE ELECTRICAL MACHINE (U 101 ) IS COUPLED, VIA A TRANSMISSION GEAR, TO TWO DIFFERENTIAL OUTPUT SHAFTS AND AN INPUT SHAFT, WHILE THE TWO WHEEL SHAFTS OF THE DIFFERENTIAL GEARS ARE RESPECTIVELY COUPLED WITH A TRANSMISSION MIDDLE SHAFT (5101 ) DRIVEN BY THE DRIVE SIDE ROTATIONAL POWER UNIT AND WITH THE INPUT SHAFT OF THE REAR DIFFERENTIAL GEAR BOX THROUGH A CLUTCH (C1 01) SO AS TO DRIVE A REAR SECTION LOAD. ALTERNATIVELY, THE THREE END SHAFT DIFFERENTIAL GEAR SYSTEM CAN BE REPLACED BY A PLANETARY GEAR TRAIN AND THE TRANSMISSION GEAR CAN BE REPLACED BY A FRICTION WHEEL. A BRAKE (6101) INSTALLED BETWEEN THE ROTOR AND STATOR OF THE ELECTRICAL MACHINE (U 101 ) CAN BE CONTROLLED TO GENERATE MOTOR DRIVING FUNCTIONS WHEN AN INPUT CURRENT IS APPLIED OR TO GENERATE VARIABLE SPEED COUPLING FUNCTIONS THROUGH AN OUTPUT CURRENT WHEN THE ELECTRICAL MACHINE (U101) IS EMPLOYED AS A GENERATOR. THE ENGINE CAN BE OPERATED AT CONSTANT SPEED OR AT A PARTIALLY ADJUSTABLE SPEED TO MAXIMIZE ENGINE EFFICIENCY AND REDUCE POLLUTION, WITH ONE PART OF THE DIFFERENTIAL SPEED OUTPUT POWER GENERATED THROUGHOUT THE DIFFERENTIAL MIXING DRIVE DEVICE (M 101 ) BEING USED FOR DRIVING THE LOAD WHILE THE REMAINDER OF THE POWER IS CONVERTED THROUGH THE GENERATOR FUNCTION OF THE ELECTRICAL MACHINE (U101) TO CHARGE THE BATTERY (6T1 01) AND THEREBY INCREASE ENERGY EFFICIENCY.FIG.1
