Electric drive assembly, four-wheel drive system, and vehicle

A four-wheel drive system, comprising a front drive bridge, a rear drive bridge, an electric drive assembly being disposed on the front drive bridge and the rear drive bridge, wherein the electric drive assembly comprises:

• a first wheel drive assembly configured to drive a first wheel and a second wheel drive assembly configured to drive a second wheel, one of the first wheel and the second wheel being a left side wheel, and the other one of the first wheel and the second wheel being a right side wheel;
• the first wheel drive assembly comprising a first motor, a first gear reduction mechanism, and a first disengaging mechanism;
• the first gear reduction mechanism being connected between the first motor and the first wheel;
• the first disengaging mechanism being configured to switch between an engagement position and a disengagement position of the first disengaging mechanism;
• when the first disengaging mechanism is switched to the engagement position of the first disengaging mechanism, power of the first motor being transmitted to the first wheel through the first gear reduction mechanism;
• and when the first disengaging mechanism is switched to the disengagement position of the first disengaging mechanism, power transmission between the first motor and the first wheel being interrupted;
• and
• the second wheel drive assembly comprising a second motor, a second gear reduction mechanism, and a second disengaging mechanism;
• the second gear reduction mechanism being connected between the second motor and the second wheel;
• the second disengaging mechanism being configured to switch between an engagement position and a disengagement position of the second disengaging mechanism;
• when the second disengaging mechanism is switched to the engagement position of the second disengaging mechanism, power of the second motor being transmitted to the second wheel through the second gear reduction mechanism;
• and when the second disengaging mechanism is switched to the disengagement position of the second disengaging mechanism, power transmission between the second motor and the second wheel being interrupted.
