The invention provides an electrically-driven bogie and a railway engineering vehicle. The electrically-driven bogie comprises a framework, an axle box device, a center plate, a primary suspension, a secondary suspension and an electric driving force transmission device. The primary suspension comprises a conical spring and a shock absorber which are respectively arranged between the framework and the axle box device; the secondary suspension is arranged on the framework and used for buffering vertical force between the bogie and a vehicle body; the center plate is arranged in the center of the framework and used for connecting the bogie and a vehicle body. The two sides of the framework are each provided with an electric driving force transmission belt device, each electric driving force transmission belt device comprises a traction motor, and the traction motors are connected with the axle gear boxes through elastic couplings. According to the electrically-driven bogie and the railway engineering vehicle, it can be guaranteed that the vehicle has good stability and stability in the running process; and vehicles can smoothly pass through the curve.
