The invention provides a gearless electrically-driven automobile braking system with a rotor capable of axially moving, and belongs to the technical field of automobile braking, the length of a stator of the gearless electrically-driven automobile braking system is larger than that of the rotor, the rotor can axially move within the action range of a stator magnetic field, and continuous torque is obtained in the gearless conversion process; the rotor is hollow, the motor shell is composed of a central column and an outer sleeve arranged on the outer side of the central column in a sleeving mode, threads are arranged on the inner side of the rotor and the outer side of the central column of the motor shell, the rotor and the central column of the motor shell are assembled together through the threads, and when the rotor rotates forwards and backwards, the rotor can move back and forth in the axial direction of the central column. Therefore, continuous axial thrust is obtained in the gearless conversion process; the electrically-driven automobile braking system adopts a gearless driving system, is small in size, simple in structure, low in manufacturing cost and convenient to manufacture, reduces rotation inertia force to the maximum extent, enables the braking process to be more stable, and improves operation performance.
