The multi-gear speed change gear transmission mechanism comprises a first power source, a one-way clutch, a planet row, a planet carrier output shaft, a gear ring output shaft, a first-gear gear, a second-gear gear, a second power source, a sun gear output shaft, a transmission shaft, a third power source, a differential mechanism, a clutch and a brake. The first power source is connected with the planet row through the one-way clutch; a planet carrier in the planet row is connected with a planet carrier output shaft, a sun gear is connected with a sun gear output shaft, a gear ring is connected with a gear ring output shaft, the gear ring output shaft is connected with a first-gear driving gear and a second-gear driving gear, and the first-gear driving gear and the second-gear driving gear are connected with a transmission shaft. The second power source is connected with the tail end of the sun gear output shaft; the third power source is connected with the transmission shaft which is connected with the differential mechanism. The transmission device has the advantages of being capable of achieving multi-gear variable speed control, high in transmission efficiency, simple in structure and the like.
