Abstract: An electric drive assembly has a first wheel drive assembly and a second wheel drive assembly. The first wheel drive assembly includes a first motor, a first gear reduction mechanism, and a first disengaging mechanism. When the first disengaging mechanism is switched to an engagement position of the first disengaging mechanism, power of the first motor is transmitted to a first wheel through the first gear reduction mechanism. The second wheel drive assembly includes a second motor, a second gear reduction mechanism, and a second disengaging mechanism. When the second disengaging mechanism is switched to an engagement position of the second disengaging mechanism, power of the second motor is transmitted to a second wheel through the second gear reduction mechanism. When the first disengaging mechanism or the second disengaging mechanism is switched to a disengagement position, the power of the motors to the corresponding wheels is interrupted.
