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. The first speed reducer and the second speed reducer are both multi-stage speed reduction and are the same in stage number, the speed ratio of the first speed reducer is the same as that of the second speed reducer, and at least two-stage speed ratios of the first speed reducer and the second speed reducer are different. 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.
