Abstract:
1. A split serial-parallel hybrid dual-power drive system is more particularly to one used to drive land, surface, underwater transportation means or aircraft, industrial machines and equipment or any other load drive by rotational kinetic energy; the split serial-parallel hybrid dual-power drive system is comprised of two or more than two separation drive systems allowing independent operation to respectively drive the load, or all loads driven individually are incorporated in a common frame; in the separation drive system of the dual-power drive system, a first drive system and a second drive system are provided; the first drive system is adapted with an active power source, a first dynamo-electrical unit essentially functioning as a generator, an optional second dynamo-electrical unit essentially functioning as a motor, and a clutch set to control the transmission status of the rotational kinetic energy; and the second drive system is adapted with another second dynamo-electrical unit essentially functioning as a motor to serve as the rotational power source for the second drive system; an optional clutch is provided to control mutual transmission or cut-off of the rotational kinetic energy between two independent drive systems; by means of the control and operation of a control system or by manual, the relation of transmission between the active rotational power source and the first dynamo-electrical unit of the separation serial-parallel hybrid drive system indicates a coupled status; 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 alternatively, through the control and operation of the clutch, the rotational kinetic energy from the active rotational power source outputs rotational kinetic energy to drive either or both of the loads of the first drive system and the second drive system; or the active rotational power source is incorporated to both of the first and the second dynamo-electrical units, and an optional rechargeable device to provide functions related to a parallel hybrid power train: accordingly, said split serial-parallel hybrid dual-power drive system relates to an innovative dual-power drive system by providing more operation functions; the split serial-parallel hybrid dual-power drive system is in a configuration of systematic coupling of the active rotational power source, the first and the second dynamo-electrical units, an operational clutch and an optional transmission unit; essentially having the assembly unit or device comprised of the active rotational power source, dynamo-electrical units, transmission unit, transmission unit, clutch, drive control unit, central control unit, rechargeable device, or auxiliary rechargeable device, or power driven load each provided with its specific function to be described as follows: the active rotational power source ( the first dynamo-electrical unit ( the second dynamo-electrical unit ( if an optional clutch ( the clutch ( the clutch ( the clutch ( the clutch ( the transmission unit ( the transmission unit ( the drive control unit ( the central control unit ( the rechargeable device ( the control interface ( the auxiliary rechargeable device ( the power driven load ( given with the engine as the active rotational power source, the split serial-parallel hybrid dual-power drive system provides any or all the following functions: the rotational kinetic energy from the engine power drives the load ( when the system is operating as a series hybrid power train, the engine is controlled to run from lower rpm up to higher rpm, or at a preset rpm to drive the first dynamo-electrical unit ( when the optional rechargeable device ( the power form the rechargeable device ( the first dynamo-electrical unit ( the first dynamo-electrical unit ( when the rechargeable device ( the rechargeable device ( the clutch ( the split serial-parallel hybrid dual-power drive system is essentially comprised of the first drive system ( furthermore, a brake ( the first drive system ( the second drive system ( alternatively, by controlling the clutch ( the primary operation functions include that when the brake ( alternatively, the power generated from the first dynamo-electrical unit ( the second dynamo-electrical unit ( when the clutch ( alternatively, the power from the rechargeable device ( furthermore, the regenerated power of dynamic braking provided by the second dynamo-electrical unit ( the operation between the rotary part of the second dynamo-electrical unit ( in addition, the rotational kinetic energy output terminal of the active rotational power source (
