DIFFERENTIAL AND VEHICLE COMPRISING SUCH DIFFERENTIAL

A differential (12) comprises two magnetic gears (20, 30) each comprising an internal rotor (22, 32), an external rotor (24, 34), and a rotor of the ferromagnetic poles (26, 36) interposed between the internal rotor ( 22, 32) and the external rotor (24,34). The internal rotor (22, 32), the external rotor (24, 34) and the ferromagnetic pole rotor (26, 36) are coaxial and suitable to rotate about a gear axis (28, 38). The internal rotors (22, 32) are suitable to be connected to a drive (40), to be placed in rotation about the respective gear axis (26, 36) by the drive motor (40) itself. The external rotors (24, 34) are suitable to be connected to respective output semi-axes (25, 35) to place them in rotation or are connected to adjustment means (50) suitable to adjust their rotation speed. In the event that the external rotors (24, 34) are suitable to be connected to respective output semi-axes (25, 35) for placing them in rotation, the rotors of the ferromagnetic poles (26, 36) are connected to adjustment means (50) suitable to adjust the rotation speed of the rotors of the ferromagnetic poles (26, 36). In the event that the external rotors (24, 34) are connected to the adjustment means (50) suitable for adjusting their rotation speed, the rotors of the ferromagnetic poles are suitable to be connected to respective output semi-axes (25, 35) to place them in rotation
