The invention discloses a torque dividing-confluence multi-gear speed change device of face gears. The torque dividing-confluence multi-gear speed change device comprises an input shaft, a clutch, a double-face gear set, two branch cylindrical gears, an output shaft, a shifting fork, a blocking piece, a photoelectric switch and a controller. When the speed change device shifts a gear, the clutch is separated, a power source is disconnected, then the face gear set rotates under the inertia effect to drive the blocking piece to pass through the optoelectronic switch, the optoelectronic switch generates a signal, at the moment, N aligned gear teeth on the face gear set just run to the position where the gear teeth are meshed with the cylindrical gear, and the shifting fork moves; the cylindrical gear is shifted to move in the axial direction of the spline and stops moving to the position where the cylindrical gear is meshed with the other face gear in the face gear set; after the cylindrical gear arrives at the
