A locking differential comprises a gearbox casing, a half shaft gear, an actuator and a shaft collar. The gearbox casing comprises a central axis and a concave part, and the half shaft gear is designed to rotate around the central axis. The half shaft gear comprises a locking component which extends outwards in the radial direction, and the locking component comprises half shaft gear sections which are separated by a plurality of grooves. The actuator encircles the central axis. The shaft collar is designed to move transversely in a bothway mode along the central axis. The shaft collar comprises a lug part and a locking component which extends inwards in the radial direction, and the locking component comprises shaft collar sections which are separated by a plurality of grooves. The actuator is designed to enable the shaft collar to move relative to the half shaft gear so that the lug part can make axial movement in the concave part. When the actuator enables the shaft collar to be moved to a locking position
