The invention discloses an energy saving type double-motor electric truck, and relates to the technical field of electric trucks. A transmission system of the energy saving type double-motor electric truck is composed of two motors different in power, two electromagnetic clutches, bearings and a gear. A control system is composed of a controller, the two electromagnetic clutches, a relay and a rotating handle. The motors and a shaft are connected through the electromagnetic clutches. The bearings are arranged between the electromagnetic clutches and the gear. When the truck is in the no-load state or the light-load state, the small-power motor is in the working state, the electromagnetic clutch connected with the small-power motor is powered on, and the large-power motor is in the stopped state. When the truck is in the heavy-load or light-load state, the large-power motor is in the working state, the electromagnetic clutch connected with the large-power motor is powered on, and the small-power motor is in the stopped state. The motors can be freely selected according to different loads, it is avoided that a small car is drawn by a large horse when the electric truck is in the no-load state or the light-load state, and therefore energy is saved.
