The invention discloses a diesel-electricity-electricity hybrid power system for a trackless truck. The diesel-electricity-electricity hybrid power system for the trackless truck comprises a power source device, an electric power transmission device and a power transmission device, the power source device comprises a diesel engine, a generator, a pantograph, a motor and a power battery, and the electric power transmission device comprises a DC/DC, an inverter, a rectifier and a circuit connected with the rectifier. The power transmission device comprises an AMT gearbox, a transmission shaft, a main speed reducer assembly and rear wheels. By means of independent or combined operation of three power sources of the diesel engine, the external power grid and the power battery, various hybrid power modes such as pure electric mode, combined driving mode and braking energy recovery mode can be achieved; according to the system, the fuel economy and the working condition adaptability of the commercial vehicle can be effectively improved, the low-power-grade engine arranged on the system can effectively reduce the working noise and improve the driving environment of the commercial vehicle, the emission performance is excellent, and the policy requirements of energy conservation and environmental protection are met.
