The present disclosure discloses a locking structure of a differential. The locking structure comprises a bi-stable electromagnetic clutch sleeved on an output axle shaft on one side of the differential. The bi-stable electromagnetic clutch comprises a movable locking disc and a fixed locking disc; the fixed locking disc is fixedly connected to a differential housing, and the movable locking disc and the fixed locking disc have face teeth that can engage with each other. The movable locking disc is sleeved on the output axle shaft, the bi-stable electromagnetic clutch drives the movable locking disc to move axially after being energized, the output axle shaft and the differential housing are locked when the movable face teeth engaged with the fixed face teeth so that the output axle shaft on either side of the differential and the differential housing have a same rotational speed and output torque.

A vehicle differential may have multiple gears and include a coil, a drive member movable in response to a magnetic field generated by the coil, with the drive member being movable between a first position and a second position. The drive member has an axis and includes a first body that is magnetically responsive, a second body coupled to the first body, an axis, an axially forward face and a stop surface axially spaced from the forward face, where the stop surface is arranged to limit movement of the drive member away from the first position. A lock member is engaged and driven by the forward face of the drive member to engage a gear of the differential when the drive member is in the second position, and the lock member is adapted to be disengaged from the gear when the drive member is in the first position.
