The utility model relates to a transmission shaft, in particular to a transmission shaft of an electrical driven instructional car. In the transmission shaft of the electrical driven instructional car, a spline safety device is arranged in a shaft tube; the spline safety device comprises a spline shaft fork, a spline sleeve, a seal ring and a safety connecting piece, and the spline shaft fork and the spline sleeve form a spline pair; a spline sleeve ring is sleeved on the spline end of the spline shaft fork and is fixedly connected with the shaft tube, and a gap is arranged between the spline sleeve and the spline shaft fork; the seal ring is arranged between the spline sleeve and the spline shaft fork; and the safety connecting piece connects the spline shaft fork and the spline sleeve to form an auxiliary spline entirety. The transmission shaft of the electrical driven instructional car is matched with a simulation control module and a power converter of an electrical driven car, and makes the control metho
