Abstract
The invention provides a hybrid power system and a vehicle, and belongs to the technical field of vehicles. The hybrid power system comprises an engine, a generator, a motor, a planetary gear train, a clutch, a brake and an output shaft. The planetary gear train comprises a sun gear, a planet gear, a planet carrier and a gear ring, the planet gear is meshed with the sun gear and meshed with an inner ring of the gear ring, and the planet carrier is connected with the planet gear. A first output shaft of the engine is connected with a second output shaft of the generator, the second output shaft is coaxially connected with the sun gear, the sun gear and the planet carrier are combined or separated through the clutch, and the gear ring is connected with the brake. The planet carrier is in transmission connection with the output shaft, and the motor is in transmission connection with the output shaft. Switching of power sources of the hybrid power system can be achieved by controlling whether the engine and the motor work or not. Moreover, the gears of the hybrid power system can be changed by controlling the combination and separation of the clutch or the brake, and the technical scheme provided by the embodiment of the invention can enrich the structural form of the hybrid power system.
