HYBRID POWER DRIVING SYSTEM AND HYBRID POWER VEHICLE

The present invention belongs to the technical field of vehicles, and discloses a hybrid drive system and a hybrid vehicle. The hybrid drive system includes an engine; a first synchronization mechanism selectively abuts against a first gear pair and a second gear pair; a second synchronization mechanism selectively abuts against a third gear pair and a fifth gear pair, so as to convert rotation of a fifth shaft into rotation of a third shaft; a third synchronization mechanism is configured to selectively abut against a fourth gear pair; a first differential mechanism is connected to the third shaft and drives, by a first drive shaft, rear wheels to rotate; a second differential mechanism is connected to a sixth shaft and drives, by a second drive shaft, front wheels to rotate; and the engine drives, by a first shaft, a second shaft to rotate for power generation by a first motor, and the first motor can transfer stored electric energy to a second motor, so as to cause the second motor to drive the fifth shaft to rotate. The hybrid drive system solves the problems of transmission performance and reliability caused by frequent gear shifting, and reduces machining difficulty.
