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 second motor, a first speed reducer, a second speed reducer, a first half shaft and a second half shaft, and the speed ratio of the first speed reducer is different from that of the second speed reducer; a shell of the first speed reducer, a shell of the second speed reducer, a shell of the first motor and a shell of the second motor are arranged in a split mode and fixedly connected together. Or at least two of the shell of the first speed reducer, the shell of the second speed reducer, the shell of the first motor and the shell of the second motor are integrated. According to the electric drive assembly, the problem of abnormal jittering or buzzing abnormal sound of an existing drive system which is independently driven by double motors in a concentrated mode on the wheel edge can be effectively solved.
