Problems solved by technology

[0002] Existing pure electric special vehicles using the main and auxiliary dual-motor drive system, when in the working state, the main drive motor drives the traveling device of the main drive shaft of the special vehicle, and the auxiliary motor drives the operation device of the special vehicle for operation; in the non-operating state, the main drive motor The auxiliary motor of the traveling device that drives the main drive shaft of the special vehicle does not work; as the special vehicle operates at a low speed, the power required by the main drive motor is small. If it is matched with a high-power main drive motor, it will easily lead to waste of motor power; In the working state, when the special vehicle is running at high speed, accelerating rapidly, or climbing a steep slope, the main drive motor needs a large power. If it is matched with a small power main drive motor, it will easily lead to insufficient power of the special vehicle; and in the non-working state, the working motor does not Work, to a certain extent, also caused idle waste of the working motor
[0003] Most of the existing motors for special-purpose vehicles are single-ended output, without clutch function, and need to cooperate with the transmission device, and the size of the transmission device is large, which is not convenient for the reasonable arrangement of special-purpose vehicles
