ABSTRACT:
A drive assembly for a bilaterally symmetrical machine such as a vehicle or aircraft is provided to precisely control and vary engine power delivered to a pair of opposed drive mechanisms of the assembly. Each drive mechanism includes a first differential clutch connected with a power source via a power splitter, a drive element such as a wheel or propeller connected with the first differential clutch, and a first braking device connected with the first differential clutch to independently control the delivery of power to the drive element. A second differential clutch may be provided for each drive mechanism to control movement of the drive mechanism in an opposite direction.
