Abstract: The present disclosure relates to the technical field of clutches, and particularly relates to an electromagnetic jaw clutch. The electromagnetic jaw clutch includes a movable gear sleeve and a fixed gear sleeve that are in engagement transmission, a fixed armature is nested to an outer side of the fixed gear sleeve, the fixed armature and the fixed gear sleeve have a gap therebetween, and have a fixed position, a solenoid is provided inside the fixed armature, a movable armature is rotatably nested to an outer side of the movable gear sleeve, the movable armature is movable along with the movable gear sleeve in an axial direction, and when the solenoid is electrified, the solenoid attracts the movable armature to the fixed armature, to cause the movable gear sleeve and the fixed gear sleeve to be engaged. The present disclosure provides an electromagnetic clutching system that has a compact structure, has no auxiliary executing structure and can be conveniently operated, which can be applied to electrically driving systems of new-energy vehicles. The system controls the transmission and disconnection of power torque.
