The invention discloses a four-wheel-drive power assembly of a hybrid electric vehicle. The four-wheel-drive power assembly is compact in structure. A first permanent magnet synchronous motor output shaft is fixedly connected with an engine output shaft and an input shaft. The input shaft is assembled on a left input shaft bearing and a right input shaft bearing. A first permanent magnet synchronous motor is connected to the left end of the first permanent magnet synchronous motor output shaft, the input shaft is sleeved with a needle bearing in an idle mode, the needle bearing is sleeved with an input shaft gear in an idle mode, and a clutch gear sleeve and a clutch gear shell are fixedly connected with the input shaft and the input shaft gear respectively. An intermediate shaft is assembled on a left intermediate shaft bearing and a right intermediate shaft bearing. A large intermediate shaft gear and a small intermediate shaft gear are assembled on the intermediate shaft. A front axle transmission shaft is connected with front wheels. A first differential is fixed to the middle of the front axle transmission shaft. A first main reduction gear is fixed to the first differential. A transmission shaft is assembled on an upper transmission shaft bearing and a lower transmission shaft bearing. A first driven bevel gear and a second driven bevel gear are connected with the transmission shaft. A second permanent magnet synchronous motor output shaft is assembled on bearings of a second permanent magnet synchronous motor output shaft.
