Patent ID: 7695402

Claim:
A split serial-parallel hybrid dual power drive system, comprising: a first drive system ( 1001 ), including: an active rotational power source ( 100 ); and a pilot drive unit ( 1000 ), the pilot drive unit further including: at least one first load; a first transmission ( 129 ) driven by said active rotational power source ( 100 ); and a coupled clutch ( 1020 ) configured to selectively transmit rotational kinetic energy between said first transmission ( 129 ) and said at least one first load a first dynamo-electrical unit ( 101 ) configured to be driven by said first transmission ( 129 ); a brake ( 901 ); a first clutch ( 112 ) configured to selectively transmit rotational kinetic energy from the first transmission ( 129 ); the output end of the first clutch ( 112 ) being configured to drive the input end of a dual-acting dynamo-electrical unit ( 1040 ); and the output end of the first clutch ( 112 ) is configured with the brake ( 901 ); and a second drive system ( 1002 ), including: at least one second dynamo-electrical unit ( 103 ); and at least one second load configured to be driven by said at least one second dynamo-electrical unit ( 103 ); and a second clutch ( 132 ) configured to selectively transmit rotational kinetic energy between the output end of said dual-acting dynamo-electrical unit and said second drive system, wherein each said at least one second load is configured to be selectively driven either by said dual-acting dynamo-electrical unit or by a respective said second dynamo-electrical unit.
