Abstract: This Application pertains to an electromagnetic dog clutch, including a movable gear sleeve and a fixed toothed sleeve that are engaged to transmit power. The movable gear sleeve is provided with contrate transmission teeth or tooth spaces, and the fixed toothed sleeve is correspondingly provided with contrate tooth spaces or transmission teeth. The transmission teeth have a uniform thickness in a direction of tooth length, tooth spaces that engage with the transmission teeth have a sector-shape in a direction of tooth space length, and the width of two sides of the tooth spaces gradually increases outwardly along the radial direction of the fixed toothed sleeve and gradually decreases inwardly along the radial direction of the fixed toothed sleeve. By employing the engagement of transmission teeth of uniform thickness and sector-shaped tooth spaces, the transmission teeth can more easily engage with the tooth spaces, and more easily realize surface contact.
