The invention relates to an electric drive assembly, a four-wheel drive system and a vehicle. The electric drive assembly comprises a drive motor, a first planetary gear speed reducing mechanism, an adjusting motor and a second planetary gear speed reducing mechanism. The first planetary gear speed reducing mechanism comprises a first input element, a first output element and a first middle element, the second planetary gear speed reducing mechanism comprises a second input element, a second output element and a second middle element, and the first middle element is in transmission connection with the second middle element. The transmission ratio between the first intermediate element and the second intermediate element is minus 1; the driving motor is connected with the first input element and the second input element at the same time, the first output element is connected with a first wheel, the second output element is connected with a second wheel, and the adjusting motor is connected to one of the first middle element and the second middle element. The electric drive assembly is only provided with one drive motor, so that the working condition efficiency of the whole vehicle is high, and the cost is low.
