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. At least one of the first speed reducer and the second speed reducer is multi-stage speed reduction, the speed ratio of the first speed reducer is the same as that of the second speed reducer, and the tooth number of a driving gear of the last-stage speed reduction gear set of the first speed reducer is different from that of a driving gear of the last-stage speed reduction gear set 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 and is arranged in a centralized mode can be solved.
