The invention relates to an electric drive assembly, a four-wheel drive system and a vehicle. The electric drive assembly comprises a first motor, a first planetary gear reducing mechanism, a second motor and a second planetary gear reducing mechanism. The first planetary gear reducing mechanism comprises a first input element, a first output element and a first intermediate element, and the second planetary gear reducing mechanism comprises a second input element, a second output element and a second intermediate element; the first intermediate element is in transmission connection with the second intermediate element, and the transmission ratio of the first intermediate element to the second intermediate element is minus 1. According to the electric drive assembly, the problem that the left and right torque consistency control difficulty of an existing four-wheel independent drive system is large is solved.
