Differential drive system, more particularly for use in a power train of a motor vehicle

A differential drive system for a vehicle, comprising:

• a differential drive device comprising a differential casing housing a differential gearset, the differential gearset being able to transmit torque from the differential casing to a first output side shaft and a second output side shaft which each drive a wheel of the vehicle, the first output side shaft and the second output side shaft extending along an axis of rotation,
• a dog clutch device comprising a first coupling member and a second coupling member, the second coupling member being able to be rotationally driven about the axis of rotation and being able to move axially along the axis of rotation with respect to the first coupling member so as to engage with the first coupling member or disengage therefrom, the first coupling member being formed by a toothed torque-transmission member of the differential drive device,
• an electromagnetic actuator comprising an annular electromagnet able to generate a magnetic field to move a mobile element between a first position associated with the engaged state of the dog clutch device, and a second position associated with the disengaged state of the dog clutch device,
• wherein the axis of rotation X is situated outside of the annular electromagnet of the electromagnetic actuator, and the differential drive system further comprises a force-transfer mechanism designed to transfer the forces of actuation of the mobile element of the electromagnetic actuator to the second coupling member of the dog clutch device.
