A differential system includes a differential and a differential disconnect mechanism. The differential includes an outer differential housing and an inner differential housing. The differential disconnect mechanism includes a disconnect clutch, first end face teeth and second end face teeth. The first end face teeth are disposed between the outer differential housing and the inner differential housing and are movably connected with the outer differential housing so that the first end face teeth can move axially and rotate synchronously relative to the outer differential housing. The second end face teeth are fixedly connected with the inner differential housing. The disconnect clutch is connected with the first end face teeth, and is configured to drive the first end face teeth to move axially relative to the second end face teeth.
