Abstract:
1. A split serial-parallel hybrid dual-power drive system, more particularly a drive system configured to drive a load by rotational kinetic energy; the split serial-parallel hybrid dual-power drive system comprising two or more drive systems each configured to independently drive the load; the dual-power drive system including a first drive system and a second drive system; the first drive system including an active power source, a first dynamo-electrical unit functioning as a generator, a second dynamo-electrical unit functioning as a motor, and a first clutch driven by a drive control unit ( the second drive system including a third dynamo-electrical unit functioning as a motor to serve as a rotational power source for the second drive system; a fourth clutch configured to control mutual transmission or cut-off of the rotational kinetic energy between the first and second drive systems; by means of the control and operation of a control system or manually, the active rotational power source and the first dynamo-electrical unit of the separation serial-parallel hybrid drive system are coupled through the first clutch, and the first dynamo-electrical unit and the second dynamo-electrical unit are separated; and the active rotational kinetic energy source drives the first dynamo-electrical unit to output electric power to further drive the second dynamo-electrical unit to operate as a motor to provide functions related to a series hybrid power train; or through the control and operation of the first clutch, the rotational kinetic energy from the active rotational power source outputs rotational kinetic energy to drive either or both of a first load of the first drive system and a second load of the second drive system through the fourth clutch; or the active rotational power source is coupled to at least one of the first and the second dynamo-electrical units, and a rechargeable device to provide functions related to a parallel hybrid power train; the split serial-parallel hybrid dual-power drive system essentially comprised of the active rotational power source, first clutch, the first and second dynamo-electrical units, second clutch, fourth clutch, drive control unit, central control unit, rechargeable device, auxiliary rechargeable device, and load as follows: for the system to operate as a series hybrid power system; when the first dynamo-electrical unit ( controls the power form the main rechargeable device ( when subject to the drive control unit ( when the first dynamo-electrical unit ( the power from the main rechargeable device ( the power of dynamic braking regenerated power by the first dynamo-electrical unit (
